Subject: [PATCH 0001/1451] pcmcia: cs: fix possible hung task and memory leak
 pccardd()

If device_register() returns error in pccardd(), it leads two issues:

1. The socket_released has never been completed, it will block
   pcmcia_unregister_socket(), because of waiting for completion
   of socket_released.
2. The device name allocated by dev_set_name() is leaked.

Fix this two issues by calling put_device() when device_register() fails.
socket_released can be completed in pcmcia_release_socket(), the name can
be freed in kobject_cleanup().

Subject: [PATCH 0002/1451] pcmcia: ds: fix refcount leak in
 pcmcia_device_add()

As the comment of device_register() says, it should use put_device()
to give up the reference in the error path. Then, insofar resources
will be freed in pcmcia_release_dev(), the error path is no longer
needed. In particular, this means that the (previously missing) dropping
of the reference to &p_dev->function_config->ref is now handled by
pcmcia_release_dev().

Subject: [PATCH 0003/1451] pcmcia: ds: fix possible name leak in error path in
 pcmcia_device_add()

Afer commit 1fa5ae857bb1 ("driver core: get rid of struct device's
bus_id string array"), the name of device is allocated dynamically.
Therefore, it needs to be freed, which is done by the driver core for
us once all references to the device are gone. Therefore, move the
dev_set_name() call immediately before the call device_register(), which
either succeeds (then the freeing will be done upon subsequent remvoal),
or puts the reference in the error call. Also, it is not unusual that the
return value of dev_set_name is not checked.

Subject: [PATCH 0028/1451] remoteproc: stm32: Clean up redundant
 dev_err_probe()

Referring to platform_get_irq()'s definition, the return value has
already been checked if ret < 0, and printed via dev_err_probe().
Calling dev_err_probe() one more time outside platform_get_irq()
is obviously redundant. Removing outside dev_err_probe() to
clean it up.

Besides, switch to use platform_get_irq_optional() since the irq
is optional here.

Subject: [PATCH 0032/1451] remoteproc: mediatek: Extract SCP common registers

This is the 1st preliminary steps for probing multi-core SCP.
The registers of config and l1tcm are common on single-core SCP
and multi-core SCP. Extract these registers out to reduce duplicated
fields in mtk_scp when multiple SCP instances are created.

This is the 2nd preliminary step for probing multi-core SCP.
Initialization of configuration and L1TCM registers is extracted
to only performed once on multi-core SCP. The rest of remoteproc
initialization procedure is similar for both single and multi-core
SCP and is applied to each core.

Subject: [PATCH 0035/1451] remoteproc: mediatek: Probe SCP cluster on
 multi-core SCP

The difference of single-core SCP and multi-core SCP device tree is
the presence of child device nodes described SCP cores. The SCP
driver populates the platform device and checks the child nodes
to identify whether it's a single-core SCP or a multi-core SCP.

Add the remoteproc instances of multi-core SCP to the SCP cluster list.
When the SCP driver is removed, it cleanup resources by walking
through the cluster list.

Subject: [PATCH 0036/1451] remoteproc: mediatek: Remove dependency of MT8195
 SCP L2TCM power control on dual-core SCP

Previously, SCP core 0 controlled the power of L2TCM and dictated that
SCP core 1 could only boot after SCP core 0. To address this constraint,
extracted the power control flow of L2TCM and made it shared
between both cores, enabling support for arbitrary boot order.

The flow for controlling L2TCM power has been incorporated into the
mt8195_scp_before_load() and mt8195_scp_stop() APIs, which are
respectively invoked during the rproc->ops->start() and
rproc->ops->stop() operations. These APIs effectively serve the same
purpose as the rproc prepare()/unprepare() APIs."

Subject: [PATCH 0037/1451] remoteproc: mediatek: Setup MT8195 SCP core 1 SRAM
 offset

Because MT8195 SCP core 0 and core 1 both boot from head of SRAM and
have the same viewpoint of SRAM, SCP has a "core 1 SRAM offset"
configuration to control the access destination of SCP core 1 to boot
core 1 from different SRAM location.

The "core 1 SRAM offset" configuration is composed by a range
and an offset. It works like a simple memory mapped mechanism.
When SCP core 1 accesses a SRAM address located in the range,
the SCP bus adds the configured offset to the address to
shift the physical destination address on SCP SRAM. This shifting is
transparent to the software running on SCP core 1.

The MT8195 SCP core 1 watchdog timeout needs to be handled in the

IRQ is wired on the same IRQ entry for core 0 watchdog timeout.
MT8195 SCP has a watchdog status register to identify the watchdog
timeout source when IRQ triggered.

Subject: [PATCH 0040/1451] remoteproc: mediatek: Refine ipi handler error
 message

The error message doesn't accurately reflect the cause of
the error. The error is due to a handler not being found,
not an invalid IPI ID.

Subject: [PATCH 0041/1451] remoteproc: zynqmp: fix TCM carveouts in lockstep
 mode

In lockstep mode following is TCM address map:

|      *TCM*         |   *R5 View* | *Linux view* |
| R5_0 ATCM (128 KB) | 0x0000_0000 | 0xFFE0_0000  |
| R5_0 BTCM (128 KB) | 0x0002_0000 | 0xFFE2_0000  |

Current driver keeps single TCM carveout in lockstep mode
as ATCM and BTCM addresses form contiguous memory region.

Although the addresses are contiguous, it is not same type
of memory. ATCM typically holds interrupt or exception code
that must be accessed at high speed. BTCM typically holds
a block of data for intensive processing, such as audio or
video processing. As both are different types of memory,
they should be allocated as different carveout. This patch
is fixing TCM carveout allocation in lockstep mode.

Subject: [PATCH 0042/1451] gfs2: Simplify function gfs2_upgrade_iopen_glock

When trying to upgrade the iopen glock, gfs2_upgrade_iopen_glock() tries
to take the iopen glock with the LM_FLAG_TRY_1CB flag set before trying
to take it without the LM_FLAG_TRY or LM_FLAG_TRY_1CB flags set.  Both
calls will cause the lock contention bast callbacks to be invoked
throughout the cluster, and we really don't need them to be invoked
twice.  Remove the first LM_FLAG_TRY_1CB call to eliminate unnecessary
dlm traffic.

Subject: [PATCH 0043/1451] gfs2: Remove freeze_go_demote_ok

Before commit b77b4a4815a9 ("gfs2: Rework freeze / thaw logic"), the
freeze glock was kept around in the glock cache in shared mode without
being actively held while a filesystem is in thawed state.  In that
state, memory pressure could have eventually evicted the freeze glock,
and the freeze_go_demote_ok callback was needed to prevent that from
happening.

With the freeze / thaw rework, the freeze glock is now always actively
held in shared mode while a filesystem is thawed, and the
freeze_go_demote_ok hack is no longer needed.

For readability and simplicity, cleanup the riscv_kexec_relocate code:

- Re-sort the first 4 `mv` instructions against `riscv_kexec_method()`
- Eliminate registers for debugging (s9,s10,s11) and storing const-value (s5,s6)
- Replace `jalr` with `jr` for no-link jump

I tested this on Qemu virt machine and works as it was.

Subject: [PATCH 0047/1451] riscv: kexec: Align the kexeced kernel entry

The current riscv boot protocol requires 2MB alignment for RV64
and 4MB alignment for RV32.

In KEXEC_FILE path, the elf_find_pbase() function should align
the kexeced kernel entry according to the requirement, otherwise
the kexeced kernel would silently BUG at the setup_vm().

Subject: [PATCH 0048/1451] riscv: kexec: Remove -fPIE for PURGATORY_CFLAGS

With CONFIG_RELOCATABLE enabled, KBUILD_CFLAGS had a -fPIE option
and then the purgatory/string.o was built to reference _ctype symbol
via R_RISCV_GOT_HI20 relocations which can't be handled by purgatory.

As a consequence, the kernel failed kexec_load_file() with:

[  880.386562] kexec_image: The entry point of kernel at 0x80200000
[  880.388650] kexec_image: Unknown rela relocation: 20
[  880.389173] kexec_image: Error loading purgatory ret=-8

So remove the -fPIE option for PURGATORY_CFLAGS to generate
R_RISCV_PCREL_HI20 relocations type making puragtory work as it was.

Subject: [PATCH 0059/1451] RISC-V: Enable cbo.zero in usermode

When Zicboz is present, enable its instruction (cbo.zero) in
usermode by setting its respective senvcfg bit. We don't bother
trying to set this bit per-task, which would also require an
interface for tasks to request enabling and/or disabling. Instead,
permanently set the bit for each hart which has the extension when
bringing it online.

This patch also introduces riscv_cpu_has_extension_[un]likely()
functions to check a specific hart's ISA bitmap for extensions.
Prior to checking the specific hart's bitmap in these functions
we try the bitmap which represents the LCD of extensions, but only
when we know it will use its optimized, alternatives path by gating
its call on CONFIG_RISCV_ALTERNATIVE. When alternatives are used, the
compiler ensures that the invocation of the LCD search becomes a
constant true or false. When it's true, even the new functions will
completely vanish from their callsites. OTOH, when the LCD check is
false, we need to do a search of the hart's ISA bitmap. Had we also
checked the LCD bitmap without the use of alternatives, then we would
have ended up with two bitmap searches instead of one.

Subject: [PATCH 0062/1451] RISC-V: selftests: Convert hwprobe test to
 kselftest API

Returning (exiting with) negative exit codes isn't user friendly,
because the user must output the exit code with the shell, convert it
from its unsigned 8-bit value back to the negative value, and then
look up where that comes from in the code (which may be multiple
places). Use the kselftests TAP interface, instead.

Subject: [PATCH 0063/1451] RISC-V: selftests: Add CBO tests

Add hwprobe test for Zicboz and its block size. Also, when Zicboz is
present, test that cbo.zero may be issued and works. Additionally
provide a command line option that enables testing that the Zicbom
instructions cause SIGILL and also that cbo.zero causes SIGILL when
Zicboz it's not present. The SIGILL tests require "opt-in" with a
command line option because the RISC-V ISA does not require
unimplemented standard opcodes to issue illegal-instruction
exceptions (but hopefully most platforms do).

Pinning the test to a subset of cpus with taskset will also restrict
the hwprobe calls to that set.

Subject: [PATCH 0064/1451] remoteproc: mediatek: Refactor single core check
 and fix retrocompatibility

In older devicetrees we had the ChromeOS EC in a node called "cros-ec"
instead of the newer "cros-ec-rpmsg", but this driver is now checking
only for the latter, breaking compatibility with those.

Besides, we can check if the SCP is single or dual core by simply
walking through the children of the main SCP node and checking if
if there's more than one "mediatek,scp-core" compatible node.

Fixes: 1fdbf0cdde98 ("remoteproc: mediatek: Probe SCP cluster on multi-core SCP")

Subject: [PATCH 0066/1451] gfs2: Don't update inode timestamps for direct
 writes

During direct reads and writes, the caller is holding the inode glock in
deferred mode, which doesn't allow metadata updates.  However, a previous
change caused callers to update the inode modification time before carrying out
direct writes, which caused the inode glock to be converted to exclusive mode
for the timestamp update, only to be immediately converted back to deferred
mode for the direct write.  This locks out other direct readers and writers
and wreaks havoc on performance.

Fix that by reverting to not updating the inode modification time for direct
writes.

 callback returning void
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The .remove() callback for a platform driver returns an int which makes
many driver authors wrongly assume it's possible to do error handling by
returning an error code. However the value returned is ignored (apart
from emitting a warning) and this typically results in resource leaks.
To improve here there is a quest to make the remove callback return
void. In the first step of this quest all drivers are converted to
.remove_new() which already returns void. Eventually after all drivers
are converted, .remove_new() will be renamed to .remove().

Trivially convert this driver from always returning zero in the remove
callback to the void returning variant.

Subject: [PATCH 0071/1451] Input: matrix_keypad - convert to platform remove
 callback returning void
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The .remove() callback for a platform driver returns an int which makes
many driver authors wrongly assume it's possible to do error handling by
returning an error code. However the value returned is ignored (apart
from emitting a warning) and this typically results in resource leaks.
To improve here there is a quest to make the remove callback return
void. In the first step of this quest all drivers are converted to
.remove_new() which already returns void. Eventually after all drivers
are converted, .remove_new() will be renamed to .remove().

Trivially convert this driver from always returning zero in the remove
callback to the void returning variant.

Subject: [PATCH 0080/1451] Input: da9055_onkey - convert to platform remove
 callback returning void
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The .remove() callback for a platform driver returns an int which makes
many driver authors wrongly assume it's possible to do error handling by
returning an error code. However the value returned is ignored (apart
from emitting a warning) and this typically results in resource leaks.
To improve here there is a quest to make the remove callback return
void. In the first step of this quest all drivers are converted to
.remove_new() which already returns void. Eventually after all drivers
are converted, .remove_new() will be renamed to .remove().

Trivially convert this driver from always returning zero in the remove
callback to the void returning variant.

Subject: [PATCH 0089/1451] Input: pm8941-pwrkey - convert to platform remove
 callback returning void
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The .remove() callback for a platform driver returns an int which makes
many driver authors wrongly assume it's possible to do error handling by
returning an error code. However the value returned is ignored (apart
from emitting a warning) and this typically results in resource leaks.
To improve here there is a quest to make the remove callback return
void. In the first step of this quest all drivers are converted to
.remove_new() which already returns void. Eventually after all drivers
are converted, .remove_new() will be renamed to .remove().

Trivially convert this driver from always returning zero in the remove
callback to the void returning variant.

Subject: [PATCH 0097/1451] Input: apbps2 - convert to platform remove callback
 returning void
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The .remove() callback for a platform driver returns an int which makes
many driver authors wrongly assume it's possible to do error handling by
returning an error code. However the value returned is ignored (apart
from emitting a warning) and this typically results in resource leaks.
To improve here there is a quest to make the remove callback return
void. In the first step of this quest all drivers are converted to
.remove_new() which already returns void. Eventually after all drivers
are converted, .remove_new() will be renamed to .remove().

Trivially convert this driver from always returning zero in the remove
callback to the void returning variant.

Subject: [PATCH 0106/1451] Input: q40kbd - convert to platform remove callback
 returning void
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The .remove() callback for a platform driver returns an int which makes
many driver authors wrongly assume it's possible to do error handling by
returning an error code. However the value returned is ignored (apart
from emitting a warning) and this typically results in resource leaks.
To improve here there is a quest to make the remove callback return
void. In the first step of this quest all drivers are converted to
.remove_new() which already returns void. Eventually after all drivers
are converted, .remove_new() will be renamed to .remove().

Trivially convert this driver from always returning zero in the remove
callback to the void returning variant.

Subject: [PATCH 0115/1451] Input: sun4i-ts - convert to platform remove
 callback returning void
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The .remove() callback for a platform driver returns an int which makes
many driver authors wrongly assume it's possible to do error handling by
returning an error code. However the value returned is ignored (apart
from emitting a warning) and this typically results in resource leaks.
To improve here there is a quest to make the remove callback return
void. In the first step of this quest all drivers are converted to
.remove_new() which already returns void. Eventually after all drivers
are converted, .remove_new() will be renamed to .remove().

Trivially convert this driver from always returning zero in the remove
callback to the void returning variant.

Subject: [PATCH 0119/1451] iommu: Add iommu_ops->identity_domain

This allows a driver to set a global static to an IDENTITY domain and
the core code will automatically use it whenever an IDENTITY domain
is requested.

By making it always available it means the IDENTITY can be used in error
handling paths to force the iommu driver into a known state. Devices
implementing global static identity domains should avoid failing their
attach_dev ops.

To make global static domains simpler allow drivers to omit their free
function and update the iommufd selftest.

Convert rockchip to use the new mechanism.

Subject: [PATCH 0120/1451] iommu: Add IOMMU_DOMAIN_PLATFORM

This is used when the iommu driver is taking control of the dma_ops,
currently only on S390 and power spapr. It is designed to preserve the
original ops->detach_dev() semantic that these S390 was built around.

Provide an opaque domain type and a 'default_domain' ops value that allows
the driver to trivially force any single domain as the default domain.

Update iommufd selftest to use this instead of set_platform_dma_ops

Subject: [PATCH 0121/1451] powerpc/iommu: Setup a default domain and remove
 set_platform_dma_ops

POWER is using the set_platform_dma_ops() callback to hook up its private
dma_ops, but this is buired under some indirection and is weirdly
happening for a BLOCKED domain as well.

For better documentation create a PLATFORM domain to manage the dma_ops,
since that is what it is for, and make the BLOCKED domain an alias for
it. BLOCKED is required for VFIO.

Also removes the leaky allocation of the BLOCKED domain by using a global
static.

Subject: [PATCH 0122/1451] iommu: Add IOMMU_DOMAIN_PLATFORM for S390

The PLATFORM domain will be set as the default domain and attached as
normal during probe. The driver will ignore the initial attach from a NULL
domain to the PLATFORM domain.

After this, the PLATFORM domain's attach_dev will be called whenever we
detach from an UNMANAGED domain (eg for VFIO). This is the same time the
original design would have called op->detach_dev().

This is temporary until the S390 dma-iommu.c conversion is merged.

This driver is nonsensical. To not block migrating the core API away from
NULL default_domains give it a hacky of a PLATFORM domain that keeps it
working exactly as it always did.

Leave some comments around to warn away any future people looking at this.

Subject: [PATCH 0124/1451] iommu/tegra-gart: Remove tegra-gart

Thierry says this is not used anymore, and doesn't think it makes sense as
an iommu driver. The HW it supports is about 10 years old now and newer HW
uses different IOMMU drivers.

As this is the only driver with a GART approach, and it doesn't really
meet the driver expectations from the IOMMU core, let's just remove it
so we don't have to think about how to make it fit in.

It has a number of identified problems:
 - The assignment of iommu_groups doesn't match the HW behavior

 - It claims to have an UNMANAGED domain but it is really an IDENTITY
   domain with a translation aperture. This is inconsistent with the core
   expectation for security sensitive operations

 - It doesn't implement a SW page table under struct iommu_domain so
   * It can't accept a map until the domain is attached
   * It forgets about all maps after the domain is detached
   * It doesn't clear the HW of maps once the domain is detached
     (made worse by having the wrong groups)

Subject: [PATCH 0125/1451] iommu/mtk_iommu_v1: Implement an IDENTITY domain

What mtk does during mtk_iommu_v1_set_platform_dma() is actually putting
the iommu into identity mode. Make this available as a proper IDENTITY
domain.

The mtk_iommu_v1_def_domain_type() from
commit 8bbe13f52cb7 ("iommu/mediatek-v1: Add def_domain_type") explains
this was needed to allow probe_finalize() to be called, but now the
IDENTITY domain will do the same job so change the returned
def_domain_type.

mkt_v1 is the only driver that returns IOMMU_DOMAIN_UNMANAGED from
def_domain_type().  This allows the next patch to enforce an IDENTITY
domain policy for this driver.

Subject: [PATCH 0126/1451] iommu: Reorganize iommu_get_default_domain_type()
 to respect def_domain_type()

Except for dart (which forces IOMMU_DOMAIN_DMA) every driver returns 0 or
IDENTITY from ops->def_domain_type().

The drivers that return IDENTITY have some kind of good reason, typically
that quirky hardware really can't support anything other than IDENTITY.

Arrange things so that if the driver says it needs IDENTITY then
iommu_get_default_domain_type() either fails or returns IDENTITY.  It will
not ignore the driver's override to IDENTITY.

Split the function into two steps, reducing the group device list to the
driver's def_domain_type() and the untrusted flag.

Then compute the result based on those two reduced variables. Fully reject
combining untrusted with IDENTITY.

Remove the debugging print on the iommu_group_store_type() failure path,
userspace should not be able to trigger kernel prints.

This makes the next patch cleaner that wants to force IDENTITY always for
ARM_IOMMU because there is no support for DMA.

Subject: [PATCH 0127/1451] iommu: Allow an IDENTITY domain as the
 default_domain in ARM32

Even though dma-iommu.c and CONFIG_ARM_DMA_USE_IOMMU do approximately the
same stuff, the way they relate to the IOMMU core is quiet different.

dma-iommu.c expects the core code to setup an UNMANAGED domain (of type
IOMMU_DOMAIN_DMA) and then configures itself to use that domain. This
becomes the default_domain for the group.

ARM_DMA_USE_IOMMU does not use the default_domain, instead it directly
allocates an UNMANAGED domain and operates it just like an external
driver. In this case group->default_domain is NULL.

If the driver provides a global static identity_domain then automatically
use it as the default_domain when in ARM_DMA_USE_IOMMU mode.

This allows drivers that implemented default_domain == NULL as an IDENTITY
translation to trivially get a properly labeled non-NULL default_domain on
ARM32 configs.

With this arrangment when ARM_DMA_USE_IOMMU wants to disconnect from the
device the normal detach_domain flow will restore the IDENTITY domain as
the default domain. Overall this makes attach_dev() of the IDENTITY domain
called in the same places as detach_dev().

This effectively migrates these drivers to default_domain mode. For
drivers that support ARM64 they will gain support for the IDENTITY
translation mode for the dma_api and behave in a uniform way.

Drivers use this by setting ops->identity_domain to a static singleton
iommu_domain that implements the identity attach. If the core detects
ARM_DMA_USE_IOMMU mode then it automatically attaches the IDENTITY domain
during probe.

Drivers can continue to prevent the use of DMA translation by returning
IOMMU_DOMAIN_IDENTITY from def_domain_type, this will completely prevent
IOMMU_DMA from running but will not impact ARM_DMA_USE_IOMMU.

This allows removing the set_platform_dma_ops() from every remaining
driver.

Remove the set_platform_dma_ops from rockchip and mkt_v1 as all it does
is set an existing global static identity domain. mkt_v1 does not support
IOMMU_DOMAIN_DMA and it does not compile on ARM64 so this transformation
is safe.

Subject: [PATCH 0130/1451] iommu/tegra-smmu: Support DMA domains in tegra

All ARM64 iommu drivers should support IOMMU_DOMAIN_DMA to enable
dma-iommu.c.

tegra is blocking dma-iommu usage, and also default_domain's, because it
wants an identity translation. This is needed for some device quirk. The
correct way to do this is to support IDENTITY domains and use
ops->def_domain_type() to return IOMMU_DOMAIN_IDENTITY for only the quirky
devices.

Add support for IOMMU_DOMAIN_DMA and force IOMMU_DOMAIN_IDENTITY mode for
everything so no behavior changes.

Subject: [PATCH 0132/1451] iommu/msm: Implement an IDENTITY domain

What msm does during msm_iommu_set_platform_dma() is actually putting the
iommu into identity mode.

Move to the new core support for ARM_DMA_USE_IOMMU by defining
ops->identity_domain.

This driver does not support IOMMU_DOMAIN_DMA, however it cannot be
compiled on ARM64 either. Most likely it is fine to support dma-iommu.c

Prior to commit 1b932ceddd19 ("iommu: Remove detach_dev callbacks") the
sun50i_iommu_detach_device() function was being called by
ops->detach_dev().

This is an IDENTITY domain so convert sun50i_iommu_detach_device() into
sun50i_iommu_identity_attach() and a full IDENTITY domain and thus hook it
back up the same was as the old ops->detach_dev().

Subject: [PATCH 0138/1451] iommu: Require a default_domain for all iommu
 drivers

At this point every iommu driver will cause a default_domain to be
selected, so we can finally remove this gap from the core code.

The following table explains what each driver supports and what the
resulting default_domain will be:

                                        ops->defaut_domain

 * G means ops->identity_domain is used
 * N/A means the driver will not compile in this configuration

ARM32 drivers select an IDENTITY default domain through either the
ops->identity_domain or directly requesting an IDENTIY domain through
alloc_domain().

In ARM64 mode tegra-smmu will still block the use of dma-iommu.c and
forces an IDENTITY domain.

S390 uses a PLATFORM domain to represent when the dma_ops are set to the
s390 iommu code.

fsl_pamu uses an PLATFORM domain.

POWER SPAPR uses PLATFORM and blocking to enable its weird VFIO mode.

The x86 drivers continue unchanged.

After this patch group->default_domain is only NULL for a short period
during bus iommu probing while all the groups are constituted. Otherwise
it is always !NULL.

This completes changing the iommu subsystem driver contract to a system
where the current iommu_domain always represents some form of translation
and the driver is continuously asserting a definable translation mode.

It resolves the confusion that the original ops->detach_dev() caused
around what translation, exactly, is the IOMMU performing after
detach. There were at least three different answers to that question in
the tree, they are all now clearly named with domain types.

Subject: [PATCH 0140/1451] iommu: Add ops->domain_alloc_paging()

This callback requests the driver to create only a __IOMMU_DOMAIN_PAGING
domain, so it saves a few lines in a lot of drivers needlessly checking
the type.

More critically, this allows us to sweep out all the
IOMMU_DOMAIN_UNMANAGED and IOMMU_DOMAIN_DMA checks from a lot of the
drivers, simplifying what is going on in the code and ultimately removing
the now-unused special cases in drivers where they did not support
IOMMU_DOMAIN_DMA.

domain_alloc_paging() should return a struct iommu_domain that is
functionally compatible with ARM_DMA_USE_IOMMU, dma-iommu.c and iommufd.

Be forwards looking and pass in a 'struct device *' argument. We can
provide this when allocating the default_domain. No drivers will look at
this.

Subject: [PATCH 0141/1451] iommu: Convert simple drivers with DOMAIN_DMA to
 domain_alloc_paging()

These drivers are all trivially converted since the function is only
called if the domain type is going to be
IOMMU_DOMAIN_UNMANAGED/DMA.

Subject: [PATCH 0142/1451] iommu: Convert remaining simple drivers to
 domain_alloc_paging()

These drivers don't support IOMMU_DOMAIN_DMA, so this commit effectively
allows them to support that mode.

The prior work to require default_domains makes this safe because every
one of these drivers is either compilation incompatible with dma-iommu.c,
or already establishing a default_domain. In both cases alloc_domain()
will never be called with IOMMU_DOMAIN_DMA for these drivers so it is safe
to drop the test.

Removing these tests clarifies that the domain allocation path is only
about the functionality of a paging domain and has nothing to do with
policy of how the paging domain is used for UNMANAGED/DMA/DMA_FQ.

Subject: [PATCH 0143/1451] iommu: Remove useless group refcounting

Several functions obtain the group reference and then release it before
returning. This gives the impression that the refcount is protecting
something for the duration of the function.

In truth all of these functions are called in places that know a device
driver is probed to the device and our locking rules already require
that dev->iommu_group cannot change while a driver is attached to the
struct device.

If this was not the case then this code is already at risk of triggering
UAF as it is racy if the dev->iommu_group is concurrently going to
NULL/free. refcount debugging will throw a WARN if kobject_get() is
called on a 0 refcount object to highlight the bug.

Remove the confusing refcounting and leave behind a comment about the
restriction.

Subject: [PATCH 0144/1451] iommu: Add generic_single_device_group()

This implements the common pattern seen in drivers of a single iommu_group
for the entire iommu driver instance. Implement this in core code so the
drivers that want this can select it from their ops.

Subject: [PATCH 0148/1451] iommu/ipmmu-vmsa: Convert to
 generic_single_device_group()

Use the new helper.

This driver is kind of weird since in ARM mode it pretends it has
per-device groups, but ARM64 mode does not.

Subject: [PATCH 0149/1451] iommu/omap: Convert to
 generic_single_device_group()

Use the new helper.

For some reason omap will probe its driver even if it doesn't load an
iommu driver. Keep this working by keeping a bool to track if the iommu
driver was started.

Subject: [PATCH 0156/1451] iommu: Improve map/unmap sanity checks

The current checks for the __IOMMU_DOMAIN_PAGING capability seem a
bit stifled, since it is quite likely now that a non-paging domain
won't have a pgsize_bitmap and/or mapping ops, and thus get caught
by the earlier condition anyway. Swap them around to test the more
fundamental condition first, then we can reasonably also upgrade
the other to a WARN_ON, since if a driver does ever expose a paging
domain without the means to actually page, it's clearly very broken.

Subject: [PATCH 0157/1451] iommu/iova: Make the rcache depot scale better

The algorithm in the original paper specifies the storage of full
magazines in the depot as an unbounded list rather than a fixed-size
array. It turns out to be pretty straightforward to do this in our
implementation with no significant loss of efficiency. This allows
the depot to scale up to the working set sizes of larger systems,
while also potentially saving some memory on smaller ones too.

Since this involves touching struct iova_magazine with the requisite
care, we may as well reinforce the comment with a proper assertion too.

Subject: [PATCH 0158/1451] iommu/iova: Manage the depot list size

Automatically scaling the depot up to suit the peak capacity of a
workload is all well and good, but it would be nice to have a way to
scale it back down again if the workload changes. To that end, add
backround reclaim that will gradually free surplus magazines if the
depot size remains above a reasonable threshold for long enough.

Subject: [PATCH 0165/1451] iommu/amd: Miscellaneous clean up when free domain

* Use the protection_domain_free() helper function to free domain.
  The function has been modified to also free memory used for the v1 and v2
  page tables. Also clear gcr3 table in v2 page table free path.

* Refactor code into cleanup_domain() for reusability. Change BUG_ON to
  WARN_ON in cleanup path.

* Protection domain dev_cnt should be read when the domain is locked.

Subject: [PATCH 0166/1451] iommu/amd: Consolidate feature detection and
 reporting logic

Currently, IOMMU driver assumes capabilities on all IOMMU instances to be
homogeneous. During early_amd_iommu_init(), the driver probes all IVHD
blocks and do sanity check to make sure that only features common among all
IOMMU instances are supported. This is tracked in the global amd_iommu_efr
and amd_iommu_efr2, which should be used whenever the driver need to check
hardware capabilities.

Therefore, introduce check_feature() and check_feature2(), and modify
the driver to adopt the new helper functions.

In addition, clean up the print_iommu_info() to avoid reporting redundant
EFR/EFR2 for each IOMMU instance.

Subject: [PATCH 0167/1451] iommu/amd: Modify logic for checking GT and PPR
 features

In order to support v2 page table, IOMMU driver need to check if the
hardware can support Guest Translation (GT) and Peripheral Page Request
(PPR) features. Currently, IOMMU driver uses global (amd_iommu_v2_present)
and per-iommu (struct amd_iommu.is_iommu_v2) variables to track the
features. There variables area redundant since we could simply just check
the global EFR mask.

Therefore, replace it with a helper function with appropriate name.

Subject: [PATCH 0169/1451] iommu/amd: Introduce iommu_dev_data.ppr

For AMD IOMMU, the PPR feature is needed to support IO page fault (IOPF).
PPR is enabled per PCI end-point device, and is configured by the PPR bit
in the IOMMU device table entry (i.e DTE[PPR]).

Introducing struct iommu_dev_data.ppr track PPR setting for each device.

Also iommu_dev_data.ppr will be set only when IOMMU supports PPR. Hence
remove redundant feature support check in set_dte_entry().

Subject: [PATCH 0170/1451] iommu/amd: Introduce iommu_dev_data.flags to track
 device capabilities

Currently we use struct iommu_dev_data.iommu_v2 to keep track of the device
ATS, PRI, and PASID capabilities. But these capabilities can be enabled
independently (except PRI requires ATS support). Hence, replace
the iommu_v2 variable with a flags variable, which keep track of the device
capabilities.

From commit 9bf49e36d718 ("PCI/ATS: Handle sharing of PF PRI Capability
with all VFs"), device PRI/PASID is shared between PF and any associated
VFs. Hence use pci_pri_supported() and pci_pasid_features() instead of
pci_find_ext_capability() to check device PRI/PASID support.

Subject: [PATCH 0172/1451] iommu/amd: Initialize iommu_device->max_pasids

Commit 1adf3cc20d69 ("iommu: Add max_pasids field in struct iommu_device")
introduced a variable struct iommu_device.max_pasids to track max
PASIDS supported by each IOMMU.

Let us initialize this field for AMD IOMMU. IOMMU core will use this value
to set max PASIDs per device (see __iommu_probe_device()).

Also remove unused global 'amd_iommu_max_pasid' variable.

Subject: [PATCH 0174/1451] iommu/tegra-smmu: Drop unnecessary error check for
 for debugfs_create_dir()

The debugfs_create_dir() function returns error pointers.
It never returns NULL.

As Baolu suggested, this patch removes the error checking for
debugfs_create_dir in tegra-smmu.c. This is because the DebugFS kernel API
is developed in a way that the caller can safely ignore the errors that
occur during the creation of DebugFS nodes. The debugfs APIs have
a IS_ERR() judge in start_creating() which can handle it gracefully. So
these checks are unnecessary.

Subject: [PATCH 0175/1451] media: qcom: camss: Fix pm_domain_on sequence in
 probe

We need to make sure camss_configure_pd() happens before
camss_register_entities() as the vfe_get() path relies on the pointer
provided by camss_configure_pd().

Fix the ordering sequence in probe to ensure the pointers vfe_get() demands
are present by the time camss_register_entities() runs.

In order to facilitate backporting to stable kernels I've moved the
configure_pd() call pretty early on the probe() function so that
irrespective of the existence of the old error handling jump labels this
patch should still apply to -next circa Aug 2023 to v5.13 inclusive.

Subject: [PATCH 0176/1451] media: qcom: camss: Fix V4L2 async notifier error
 path

Previously the jump label err_cleanup was used higher in the probe()
function to release the async notifier however the async notifier
registration was moved later in the code rendering the previous four jumps
redundant.

Rename the label from err_cleanup to err_v4l2_device_unregister to capture
what the jump does.

Subject: [PATCH 0178/1451] media: qcom: camss: Fix vfe_get() error jump

Right now it is possible to do a vfe_get() with the internal reference
count at 1. If vfe_check_clock_rates() returns non-zero then we will
leave the reference count as-is and

run:
- pm_runtime_put_sync()
- vfe->ops->pm_domain_off()

skip:
- camss_disable_clocks()

Subsequent vfe_put() calls will when the ref-count is non-zero
unconditionally run:

- pm_runtime_put_sync()
- vfe->ops->pm_domain_off()
- camss_disable_clocks()

vfe_get() should not attempt to roll-back on error when the ref-count is
non-zero as the upper layers will still do their own vfe_put() operations.

vfe_put() will drop the reference count and do the necessary power
domain release, the cleanup jumps in vfe_get() should only be run when
the ref-count is zero.

Subject: [PATCH 0179/1451] media: qcom: camss: Fix VFE-17x
 vfe_disable_output()

There are two problems with the current vfe_disable_output() routine.

Firstly we rightly use a spinlock to protect output->gen2.active_num
everywhere except for in the IDLE timeout path of vfe_disable_output().
Even if that is not racy "in practice" somehow it is by happenstance not
by design.

Secondly we do not get consistent behaviour from this routine. On
sc8280xp 50% of the time I get "VFE idle timeout - resetting". In this
case the subsequent capture will succeed. The other 50% of the time, we
don't hit the idle timeout, never do the VFE reset and subsequent
captures stall indefinitely.

Rewrite the vfe_disable_output() routine to

- Quiesce write masters with vfe_wm_stop()
- Set active_num = 0

remembering to hold the spinlock when we do so followed by

- Reset the VFE

Testing on sc8280xp and sdm845 shows this to be a valid fix.

Subject: [PATCH 0180/1451] media: qcom: camss: Fix VFE-480
 vfe_disable_output()

vfe-480 is copied from vfe-17x and has the same racy idle timeout bug as in
17x.

Fix the vfe_disable_output() logic to no longer be racy and to conform
to the 17x way of quiescing and then resetting the VFE.

Subject: [PATCH 0184/1451] media: qcom: camss: Fix csid-gen2 for test pattern
 generator

In the current driver csid Test Pattern Generator (TPG) doesn't work.
This change:
- fixes writing frame width and height values into CSID_TPG_DT_n_CFG_0
- fixes the shift by one between test_pattern control value and the
  actual pattern.
- drops fixed VC of 0x0a which testing showed prohibited some test
  patterns in the CSID to produce output.
So that TPG starts working, but with the below limitations:
- only test_pattern=9 works as it should
- test_pattern=8 and test_pattern=7 produce black frame (all zeroes)
- the rest of test_pattern's don't work (yavta doesn't get the data)
- regardless of the CFA pattern set by 'media-ctl -V' the actual pixel
  order is always the same (RGGB for any RAW8 or RAW10P format in
  4608x2592 resolution).

Tested with:

RAW10P format, VC0:
 media-ctl -V '"msm_csid0":0[fmt:SRGGB10/4608x2592 field:none]'
 media-ctl -V '"msm_vfe0_rdi0":0[fmt:SRGGB10/4608x2592 field:none]'
 media-ctl -l '"msm_csid0":1->"msm_vfe0_rdi0":0[1]'

 yavta -B capture-mplane --capture=3 -n 3 -f SRGGB10P -s 4608x2592 /dev/video0

RAW10P format, VC1:
 media-ctl -V '"msm_csid0":2[fmt:SRGGB10/4608x2592 field:none]'
 media-ctl -V '"msm_vfe0_rdi1":0[fmt:SRGGB10/4608x2592 field:none]'

Subject: [PATCH 0186/1451] media: qcom/camss: use 1X16 formats instead of 2X8
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Platforms with qcom-camss use CSI-2, which means 1X16 is more correct
than 2X8. The fact that qcom-camss supported only 2X8 meant it was
incompatible with camera sensors it should have been compatible with.

For example, the ov5645 driver (correctly) reports that its format is
UYVY8_1X16 (after ba449bb56203aedc4530a82b0f3f83358808b7f2).
Since qcom-camss only supports 2X8, the qcom-camss system is
incompatible with the ov5645 driver, even though they should be
compatible.

This patch replaces all uses of UYVY8_2X8/VYUY8_2X8/YUYV8_2X8/YVYU8_2X8
with the equivalent 1X16 formats.

Subject: [PATCH 0188/1451] media: cros-ec-cec: Manage an array of ports

To support multiple CEC ports, change cros_ec_cec to contain an array of
ports, each with their own CEC adapter, etc.

For now, only create a single port and use that port everywhere, so
there is no functional change. Support for multiple ports will be added
in the following patches.

Subject: [PATCH 0189/1451] media: cros-ec-cec: Support multiple ports in
 set/get host commands

Reuse the top four bits of the cmd field to specify the port number.
The reason for doing this as opposed to adding a separate uint8_t field
is it avoids the need to add new versions of these commands. The change
is backwards compatible since these bits were previously always zero, so
the default behaviour is to always operate on port 0.

Subject: [PATCH 0190/1451] media: cros-ec-cec: Support multiple ports in write
 command

Add a v1 of the CEC write command which contains a port parameter. Check
which versions of the write command the EC supports and use the highest
supported version. If it only supports v0, check that there is only one
port. With v0, the EC will assume all write commands are for port 0.

Subject: [PATCH 0192/1451] media: cros-ec-cec: Support receiving messages from
 multiple ports

Currently, received messages are sent from the EC in the cec_message
MKBP event. Since the size of ec_response_get_next_data_v1 is 16 bytes,
which is also the maximum size of a CEC message, there is no space to
add a port parameter. Increasing the size of
ec_response_get_next_data_v1 is an option, but this would increase
EC-kernel traffic for all MKBP event types.

Instead, use an event to notify that data is ready, and add a new read
command to read the data.

For backwards compatibility with old EC firmware, continue to handle
cec_message events as well.

Subject: [PATCH 0194/1451] media: cros-ec-cec: Get number of CEC ports from EC

Add a new CEC port count host command and use it to query the number of
CEC ports from the EC. If the host command is not supported then it must
be old EC firmware which only supports one port, so fall back to
assuming one port.

Subject: [PATCH 0203/1451] media: imx-jpeg: initiate a drain of the capture
 queue in dynamic resolution change

The last buffer from before the change must be marked,
with the V4L2_BUF_FLAG_LAST flag,
similarly to the Drain sequence above.

Meanwhile if V4L2_DEC_CMD_STOP is sent before
the source change triggered,
we need to restore the is_draing flag after
the draining in dynamic resolution change.

Subject: [PATCH 0205/1451] media: hantro: Check whether reset op is defined
 before use

The i.MX8MM/N/P does not define the .reset op since reset of the VPU is
done by genpd. Check whether the .reset op is defined before calling it
to avoid NULL pointer dereference.

Note that the Fixes tag is set to the commit which removed the reset op
from i.MX8M Hantro G2 implementation, this is because before this commit
all the implementations did define the .reset op.

Subject: [PATCH 0206/1451] media: verisilicon: Do not enable G2 postproc
 downscale if source is narrower than destination

In case of encoded input VP9 data width that is not multiple of macroblock
size, which is 16 (e.g. 1080x1920 frames, where 1080 is multiple of 8), the
width is padded to be a multiple of macroblock size (for 1080x1920 frames,
that is 1088x1920).

The hantro_postproc_g2_enable() checks whether the encoded data width is
equal to decoded frame width, and if not, enables down-scale mode. For a
frame where input is 1080x1920 and output is 1088x1920, this is incorrect
as no down-scale happens, the frame is only padded. Enabling the down-scale
mode in this case results in corrupted frames.

Fix this by adjusting the check to test whether encoded data width is
greater than decoded frame width, and only in that case enable the
down-scale mode.

To generate input test data to trigger this bug, use e.g.:
$ gst-launch-1.0 videotestsrc ! video/x-raw,width=272,height=256,format=I420 ! \
                 vp9enc ! matroskamux ! filesink location=/tmp/test.vp9
To trigger the bug upon decoding (note that the NV12 must be forced, as
that assures the output data would pass the G2 postproc):
$ gst-launch-1.0 filesrc location=/tmp/test.vp9 ! matroskademux ! vp9parse ! \
                 v4l2slvp9dec ! video/x-raw,format=NV12 ! videoconvert ! fbdevsink

Subject: [PATCH 0207/1451] media: gspca: cpia1: shift-out-of-bounds in
 set_flicker

Syzkaller reported the following issue:
UBSAN: shift-out-of-bounds in drivers/media/usb/gspca/cpia1.c:1031:27
shift exponent 245 is too large for 32-bit type 'int'

When the value of the variable "sd->params.exposure.gain" exceeds the
number of bits in an integer, a shift-out-of-bounds error is reported. It
is triggered because the variable "currentexp" cannot be left-shifted by
more than the number of bits in an integer. In order to avoid invalid
range during left-shift, the conditional expression is added.

Subject: [PATCH 0216/1451] media: staging: ipu3-imgu: Initialise
 height_per_slice in the stripes

While playing with low resolutions for the grid, it appeared that
height_per_slice is not initialised if we are not using both stripes for
the calculations. This pattern occurs three times:
- for the awb_fr processing block
- for the af processing block
- for the awb processing block

The idea of this small portion of code is to reduce complexity in
loading the statistics, it could be done also when only one stripe is
used. Fix it by getting this initialisation code outside of the else()
test case.

 is initialized.

During probe ivsc ace device, acpi_dev_clear_dependencies() will be
called to clear the consumer and supplier relationship between camera
sensor device and ivsc device. But IPU bridge will setup the connection
swnodes for ivsc device and camera sensor device based on this consumer
and supplier relationship. This patch defers ivsc ace's probe to make
sure IPU bridge is initialized before this consumer and supplier
relationship between camera sensor device and IVSC device is cleared.

Subject: [PATCH 0223/1451] media: i2c: max9286: Fix some redundant
 of_node_put() calls

This is odd to have a of_node_put() just after a for_each_child_of_node()
or a for_each_endpoint_of_node() loop. It should already be called
during the last iteration.

Remove these calls.

Subject: [PATCH 0224/1451] media: i2c: imx415: Use v4l2_subdev_get_fmt()

The imx415 driver uses the subdev active state, there's
no need to implement the .get_fmt() operation manually. Use
the v4l2_subdev_get_fmt() helper instead.

Routing support, through the subdev .set_routing() operation, requires

anywhere. Fix it by expanding the operation's documentation to indicate
that subdevs must set the V4L2_SUBDEV_FL_STREAMS flag.

Convert enum->pointer for data in the match tables, so that

bus type match support added to it.

Replace enum->struct *video_i2c_chip for data in the match table. Simplify
the probe() by replacing device_get_match_data() and ID lookup for
retrieving data by i2c_get_match_data().

Subject: [PATCH 0229/1451] media: i2c: mt9v032: Extend match support for OF
 tables

The driver has an OF match table, still, it uses an ID lookup table for
retrieving match data. Currently, the driver is working on the
assumption that an I2C device registered via OF will always match a
legacy I2C device ID. The correct approach is to have an OF device ID
table using i2c_get_match_data() if the devices are registered via OF/ID.

Unify the OF/ID table by using mt9v032_model_info as match data for both
these tables and replace the ID lookup table for the match data by
i2c_get_match_data() and simplifly probe().

Subject: [PATCH 0231/1451] media: i2c: ov7670: Extend match support for OF
 tables

The driver has an OF match table, still, it uses an ID lookup table for
retrieving match data. Currently, the driver is working on the
assumption that an I2C device registered via OF will always match a
legacy I2C device ID. The correct approach is to have an OF device ID
table using i2c_get_match_data() if the devices are registered via OF/ID.

Unify the OF/ID table by using struct ov7670_devtype as match data for
both these tables and replace the ID lookup table for the match data by
i2c_get_match_data().

Split the array ov7670_devdata[] as individual variables, and
make lines shorter by referring to e.g. &ov7670_devdata instead of
&ov7670_devdata[MODEL_OV7670].

Drop enum ov7670_model as there is no user.

While at it, remove the trailing comma in the terminator entry for the OF
table making code robust against (theoretical) misrebases or other similar
things where the new entry goes _after_ the termination without the
compiler noticing.

Subject: [PATCH 0235/1451] media: i2c: Use pm_runtime_resume_and_get()

Simplify error handling by using pm_runtime_resume_and_get() instead of
pm_runtime_get_sync() with a put call in the error path.

Subject: [PATCH 0240/1451] media: dt-bindings: Add OV5642

As explained in the description text from trivial-devices.yaml:

"This is a list of trivial I2C and SPI devices that have simple device tree
bindings, consisting only of a compatible field, an address and possibly an
interrupt line."

A camera device does not fall into this category as it needs other
properties such as regulators, reset and powerdown GPIOs, clocks,
media endpoint.

Remove the OV5642 entry from trivial-devices.yaml and add its own
ovti,ov5642.yaml.

Subject: [PATCH 0242/1451] media: v4l2-subdev: Document and enforce
 .s_stream() requirements

The subdev .s_stream() operation must not be called to start an already
started subdev, or stop an already stopped one. This requirement has
never been formally documented. Fix it, and catch possible offenders
with a WARN_ON() in the call_s_stream() wrapper.

Subject: [PATCH 0260/1451] media: i2c: ov13b10: Drop check for reentrant
 .s_stream()

The subdev .s_stream() operation shall not be called to start streaming
on an already started subdev, or stop streaming on a stopped subdev.
Remove the check that guards against that condition.

The subdev .s_stream() operation shall not be called to start streaming
on an already started subdev, or stop streaming on a stopped subdev.
Remove the check that guards against that condition.

Subject: [PATCH 0275/1451] Documentation: media: camera-sensor: Improve power

Camera sensor drivers are highly subject to cargo cult programming, with
back practices being copied from old to new drivers. In particular, many
drivers implement system and runtime PM incorrectly. As a first step
towards fixing this situation, refactor and expand the power management
documentation to detail correct usage of system and runtime PM.

+Camera sensors are used in conjunction with other devices to form a camera
+pipeline. They must obey the rules listed herein to ensure coherent power
+management over the pipeline.
+
+Camera sensor drivers are responsible for controlling the power state of the
+device they otherwise control as well. They shall use runtime PM to manage
+power states. Runtime PM shall be enabled at probe time and disabled at remove
+time. Drivers should enable runtime PM autosuspend.
+
+The runtime PM handlers shall handle clocks, regulators, GPIOs, and other
+system resources required to power the sensor up and down. For drivers that
+don't use any of those resources (such as drivers that support ACPI systems
+only), the runtime PM handlers may be left unimplemented.
+
+In general, the device shall be powered on at least when its registers are
+being accessed and when it is streaming. Drivers should use
+``pm_runtime_resume_and_get()`` when starting streaming and
+``pm_runtime_put()`` or ``pm_runtime_put_autosuspend()`` when stopping
+streaming. They may power the device up at probe time (for example to read
+identification registers), but should not keep it powered unconditionally after
+probe.
+
+At system suspend time, the whole camera pipeline must stop streaming, and
+restart when the system is resumed. This requires coordination between the
+camera sensor and the rest of the camera pipeline. Bridge drivers are
+responsible for this coordination, and instruct camera sensors to stop and
+restart streaming by calling the appropriate subdev operations
+(``.s_stream()``, ``.enable_streams()`` or ``.disable_streams()``). Camera
+sensor drivers shall therefore **not** keep track of the streaming state to
+stop streaming in the PM suspend handler and restart it in the resume handler.
+Drivers should in general not implement the system PM handlers.
+
+Camera sensor drivers shall **not** implement the subdev ``.s_power()``
+operation, as it is deprecated. While this operation is implemented in some
+existing drivers as they predate the deprecation, new drivers shall use runtime
+PM instead. If you feel you need to begin calling ``.s_power()`` from an ISP or
+a bridge driver, instead add runtime PM support to the sensor driver you are
+using and drop its ``.s_power()`` handler.
+
+See examples of runtime PM handling in e.g. ``drivers/media/i2c/ov8856.c`` and
+``drivers/media/i2c/ccs/ccs-core.c``. The two drivers work in both ACPI and DT
+based systems.

Stopping streaming on a camera pipeline at system suspend time, and
restarting it at system resume time, requires coordinated action between
the bridge driver and the camera sensor driver. This is handled by the
bridge driver calling the sensor's .s_stream() handler at system suspend
and resume time. There is thus no need for the sensor to independently
implement system sleep PM operations. Drop them.

The streaming field of the driver's private structure is now unused,
drop it as well.

Subject: [PATCH 0279/1451] media: i2c: hi846: Drop system suspend and resume
 handlers

Stopping streaming on a camera pipeline at system suspend time, and
restarting it at system resume time, requires coordinated action between
the bridge driver and the camera sensor driver. This is handled by the
bridge driver calling the sensor's .s_stream() handler at system suspend
and resume time. There is thus no need for the sensor to independently
implement system sleep PM operations. Drop them.

Now that the runtime PM operations are not called from the system PM
handlers, the sensor is guaranteed not to be streaming when the runtime
PM resume handler is called, and to have been stopped already when the
runtime PM suspend handler is called. Drop the manual stream start/stop
from the runtime PM handlers.

Subject: [PATCH 0294/1451] media: i2c: ov13b10: Drop stream handling in
 runtime PM handlers

The sensor is guaranteed not to be streaming when the runtime PM resume
handler is called, as the resume handler is only called from the
.s_stream() operation when starting streaming. Similarly, the sensor has
been stopped when the runtime PM suspend handler is called. There is
thus no need for manual stream start/stop from the runtime PM handlers.
Drop them.

The streaming field of the driver's private structure is now unused,
drop it as well.

the bridge driver and the camera sensor driver. This is handled by the
bridge driver calling the sensor's .s_stream() handler at system suspend
and resume time. There is thus no need for the sensor to independently
implement system sleep PM operations. Drop them.

The streaming field of the driver's private structure is now unused,
drop it as well.

Subject: [PATCH 0299/1451] media: bttv: fix use after free error due to
 btv->timeout timer

There may be some a race condition between timer function
bttv_irq_timeout and bttv_remove. The timer is setup in
probe and there is no timer_delete operation in remove
function. When it hit kfree btv, the function might still be
invoked, which will cause use after free bug.

This bug is found by static analysis, it may be false positive.

Fix it by adding del_timer_sync invoking to the remove function.

It is possible that dma_request_chan will return EPROBE_DEFER,
which means that dma->xdev->dev is not ready yet. In this case,
dev_err(dma->xdev->dev), there will be no output. This patch
fixes the bug.

Subject: [PATCH 0306/1451] media: dt-bindings: samsung,exynos4212-fimc-is:
 replace duplicate pmu node with phandle

The FIMC IS camera must access the PMU (Power Management Unit) IO memory
to control camera power.  This was achieved by duplicating the PMU node
as its child like:

  soc@0 {
    system-controller@10020000 { ... }; // Real PMU

    camera@11800000 {
      fimc-is@12000000 {
        // FIMC IS camera node
        pmu@10020000 {
          reg = <0x10020000 0x3000>; // Fake PMU node
        };
      };
    };
  };

This is not a correct representation of the hardware.  Mapping the PMU
(Power Management Unit) IO memory should be via syscon-like phandle
(samsung,pmu-syscon, already used for other drivers), not by duplicating
"pmu" Devicetree node inside the FIMC IS.

Subject: [PATCH 0308/1451] media: exynos4-is: fimc-is: replace duplicate pmu
 node with phandle

Devicetree for the FIMC IS camera included duplicated PMU node as its
child like:

  soc@0 {
    system-controller@10020000 { ... }; // Real PMU

    camera@11800000 {
      fimc-is@12000000 {
        // FIMC IS camera node
        pmu@10020000 {
          reg = <0x10020000 0x3000>; // Fake PMU node
        };
      };
    };
  };

This is not a correct representation of the hardware.  Mapping the PMU
(Power Management Unit) IO memory should be via syscon-like phandle
(samsung,pmu-syscon, already used for other drivers), not by duplicating
"pmu" Devicetree node inside the FIMC IS.  Backward compatibility is
preserved.

-Videobuf Framework
-==================
-
-Author: Jonathan Corbet <corbet@lwn.net>
-
-Current as of 2.6.33
-
-.. note::
-
-   The videobuf framework was deprecated in favor of videobuf2. Shouldn't
-   be used on new drivers.
-
-Introduction
-------------
-
-The videobuf layer functions as a sort of glue layer between a V4L2 driver
-and user space.  It handles the allocation and management of buffers for
-the storage of video frames.  There is a set of functions which can be used
-to implement many of the standard POSIX I/O system calls, including read(),
-poll(), and, happily, mmap().  Another set of functions can be used to
-implement the bulk of the V4L2 ioctl() calls related to streaming I/O,
-including buffer allocation, queueing and dequeueing, and streaming
-control.  Using videobuf imposes a few design decisions on the driver
-author, but the payback comes in the form of reduced code in the driver and
-a consistent implementation of the V4L2 user-space API.
-
-Buffer types
-------------
-
-Not all video devices use the same kind of buffers.  In fact, there are (at
-least) three common variations:
-
- - Buffers which are scattered in both the physical and (kernel) virtual
-   address spaces.  (Almost) all user-space buffers are like this, but it
-   makes great sense to allocate kernel-space buffers this way as well when
-   it is possible.  Unfortunately, it is not always possible; working with
-   this kind of buffer normally requires hardware which can do
-   scatter/gather DMA operations.
-
- - Buffers which are physically scattered, but which are virtually
-   contiguous; buffers allocated with vmalloc(), in other words.  These
-   buffers are just as hard to use for DMA operations, but they can be
-   useful in situations where DMA is not available but virtually-contiguous
-   buffers are convenient.
-
- - Buffers which are physically contiguous.  Allocation of this kind of
-   buffer can be unreliable on fragmented systems, but simpler DMA
-   controllers cannot deal with anything else.
-
-Videobuf can work with all three types of buffers, but the driver author
-must pick one at the outset and design the driver around that decision.
-
-[It's worth noting that there's a fourth kind of buffer: "overlay" buffers
-which are located within the system's video memory.  The overlay
-functionality is considered to be deprecated for most use, but it still
-shows up occasionally in system-on-chip drivers where the performance
-benefits merit the use of this technique.  Overlay buffers can be handled
-as a form of scattered buffer, but there are very few implementations in
-the kernel and a description of this technique is currently beyond the
-scope of this document.]
-
-Data structures, callbacks, and initialization
-----------------------------------------------
-
-Depending on which type of buffers are being used, the driver should
-include one of the following files:
-
-.. code-block:: none
-
-    <media/videobuf-dma-sg.h>		/* Physically scattered */
-    <media/videobuf-vmalloc.h>		/* vmalloc() buffers	*/
-    <media/videobuf-dma-contig.h>	/* Physically contiguous */
-
-The driver's data structure describing a V4L2 device should include a
-struct videobuf_queue instance for the management of the buffer queue,
-along with a list_head for the queue of available buffers.  There will also
-need to be an interrupt-safe spinlock which is used to protect (at least)
-the queue.
-
-The next step is to write four simple callbacks to help videobuf deal with
-the management of buffers:
-
-.. code-block:: none
-
-    struct videobuf_queue_ops {
-	int (*buf_setup)(struct videobuf_queue *q,
-			 unsigned int *count, unsigned int *size);
-	int (*buf_prepare)(struct videobuf_queue *q,
-			   struct videobuf_buffer *vb,
-			   enum v4l2_field field);
-	void (*buf_queue)(struct videobuf_queue *q,
-			  struct videobuf_buffer *vb);
-	void (*buf_release)(struct videobuf_queue *q,
-			    struct videobuf_buffer *vb);
-    };
-
-buf_setup() is called early in the I/O process, when streaming is being
-initiated; its purpose is to tell videobuf about the I/O stream.  The count
-parameter will be a suggested number of buffers to use; the driver should
-check it for rationality and adjust it if need be.  As a practical rule, a
-minimum of two buffers are needed for proper streaming, and there is
-usually a maximum (which cannot exceed 32) which makes sense for each
-device.  The size parameter should be set to the expected (maximum) size
-for each frame of data.
-
-Each buffer (in the form of a struct videobuf_buffer pointer) will be
-passed to buf_prepare(), which should set the buffer's size, width, height,
-and field fields properly.  If the buffer's state field is
-VIDEOBUF_NEEDS_INIT, the driver should pass it to:
-
-.. code-block:: none
-
-    int videobuf_iolock(struct videobuf_queue* q, struct videobuf_buffer *vb,
-			struct v4l2_framebuffer *fbuf);
-
-Among other things, this call will usually allocate memory for the buffer.
-Finally, the buf_prepare() function should set the buffer's state to
-VIDEOBUF_PREPARED.
-
-When a buffer is queued for I/O, it is passed to buf_queue(), which should
-put it onto the driver's list of available buffers and set its state to
-VIDEOBUF_QUEUED.  Note that this function is called with the queue spinlock
-held; if it tries to acquire it as well things will come to a screeching
-halt.  Yes, this is the voice of experience.  Note also that videobuf may
-wait on the first buffer in the queue; placing other buffers in front of it
-could again gum up the works.  So use list_add_tail() to enqueue buffers.
-
-Finally, buf_release() is called when a buffer is no longer intended to be
-used.  The driver should ensure that there is no I/O active on the buffer,
-then pass it to the appropriate free routine(s):
-
-.. code-block:: none
-
-    /* Scatter/gather drivers */
-    int videobuf_dma_unmap(struct videobuf_queue *q,
-			   struct videobuf_dmabuf *dma);
-    int videobuf_dma_free(struct videobuf_dmabuf *dma);
-
-    /* vmalloc drivers */
-    void videobuf_vmalloc_free (struct videobuf_buffer *buf);
-
-    /* Contiguous drivers */
-    void videobuf_dma_contig_free(struct videobuf_queue *q,
-				  struct videobuf_buffer *buf);
-
-One way to ensure that a buffer is no longer under I/O is to pass it to:
-
-.. code-block:: none
-
-    int videobuf_waiton(struct videobuf_buffer *vb, int non_blocking, int intr);
-
-Here, vb is the buffer, non_blocking indicates whether non-blocking I/O
-should be used (it should be zero in the buf_release() case), and intr
-controls whether an interruptible wait is used.
-
-File operations
----------------
-
-At this point, much of the work is done; much of the rest is slipping
-videobuf calls into the implementation of the other driver callbacks.  The
-first step is in the open() function, which must initialize the
-videobuf queue.  The function to use depends on the type of buffer used:
-
-.. code-block:: none
-
-    void videobuf_queue_sg_init(struct videobuf_queue *q,
-				struct videobuf_queue_ops *ops,
-				struct device *dev,
-				spinlock_t *irqlock,
-				enum v4l2_buf_type type,
-				enum v4l2_field field,
-				unsigned int msize,
-				void *priv);
-
-    void videobuf_queue_vmalloc_init(struct videobuf_queue *q,
-				struct videobuf_queue_ops *ops,
-				struct device *dev,
-				spinlock_t *irqlock,
-				enum v4l2_buf_type type,
-				enum v4l2_field field,
-				unsigned int msize,
-				void *priv);
-
-    void videobuf_queue_dma_contig_init(struct videobuf_queue *q,
-				       struct videobuf_queue_ops *ops,
-				       struct device *dev,
-				       spinlock_t *irqlock,
-				       enum v4l2_buf_type type,
-				       enum v4l2_field field,
-				       unsigned int msize,
-				       void *priv);
-
-In each case, the parameters are the same: q is the queue structure for the
-device, ops is the set of callbacks as described above, dev is the device
-structure for this video device, irqlock is an interrupt-safe spinlock to
-protect access to the data structures, type is the buffer type used by the
-device (cameras will use V4L2_BUF_TYPE_VIDEO_CAPTURE, for example), field
-describes which field is being captured (often V4L2_FIELD_NONE for
-progressive devices), msize is the size of any containing structure used
-around struct videobuf_buffer, and priv is a private data pointer which
-shows up in the priv_data field of struct videobuf_queue.  Note that these
-are void functions which, evidently, are immune to failure.
-
-V4L2 capture drivers can be written to support either of two APIs: the
-read() system call and the rather more complicated streaming mechanism.  As
-a general rule, it is necessary to support both to ensure that all
-applications have a chance of working with the device.  Videobuf makes it
-easy to do that with the same code.  To implement read(), the driver need
-only make a call to one of:
-
-.. code-block:: none
-
-    ssize_t videobuf_read_one(struct videobuf_queue *q,
-			      char __user *data, size_t count,
-			      loff_t *ppos, int nonblocking);
-
-    ssize_t videobuf_read_stream(struct videobuf_queue *q,
-				 char __user *data, size_t count,
-				 loff_t *ppos, int vbihack, int nonblocking);
-
-Either one of these functions will read frame data into data, returning the
-amount actually read; the difference is that videobuf_read_one() will only
-read a single frame, while videobuf_read_stream() will read multiple frames
-if they are needed to satisfy the count requested by the application.  A
-typical driver read() implementation will start the capture engine, call
-one of the above functions, then stop the engine before returning (though a
-smarter implementation might leave the engine running for a little while in
-anticipation of another read() call happening in the near future).
-
-The poll() function can usually be implemented with a direct call to:
-
-.. code-block:: none
-
-    unsigned int videobuf_poll_stream(struct file *file,
-				      struct videobuf_queue *q,
-				      poll_table *wait);
-
-Note that the actual wait queue eventually used will be the one associated
-with the first available buffer.
-
-When streaming I/O is done to kernel-space buffers, the driver must support
-the mmap() system call to enable user space to access the data.  In many
-V4L2 drivers, the often-complex mmap() implementation simplifies to a
-single call to:
-
-.. code-block:: none
-
-    int videobuf_mmap_mapper(struct videobuf_queue *q,
-			     struct vm_area_struct *vma);
-
-Everything else is handled by the videobuf code.
-
-The release() function requires two separate videobuf calls:
-
-.. code-block:: none
-
-    void videobuf_stop(struct videobuf_queue *q);
-    int videobuf_mmap_free(struct videobuf_queue *q);
-
-The call to videobuf_stop() terminates any I/O in progress - though it is
-still up to the driver to stop the capture engine.  The call to
-videobuf_mmap_free() will ensure that all buffers have been unmapped; if
-so, they will all be passed to the buf_release() callback.  If buffers
-remain mapped, videobuf_mmap_free() returns an error code instead.  The
-purpose is clearly to cause the closing of the file descriptor to fail if
-buffers are still mapped, but every driver in the 2.6.32 kernel cheerfully
-ignores its return value.
-
-ioctl() operations
-------------------
-
-The V4L2 API includes a very long list of driver callbacks to respond to
-the many ioctl() commands made available to user space.  A number of these
-- those associated with streaming I/O - turn almost directly into videobuf
-calls.  The relevant helper functions are:
-
-.. code-block:: none
-
-    int videobuf_reqbufs(struct videobuf_queue *q,
-			 struct v4l2_requestbuffers *req);
-    int videobuf_querybuf(struct videobuf_queue *q, struct v4l2_buffer *b);
-    int videobuf_qbuf(struct videobuf_queue *q, struct v4l2_buffer *b);
-    int videobuf_dqbuf(struct videobuf_queue *q, struct v4l2_buffer *b,
-		       int nonblocking);
-    int videobuf_streamon(struct videobuf_queue *q);
-    int videobuf_streamoff(struct videobuf_queue *q);
-
-So, for example, a VIDIOC_REQBUFS call turns into a call to the driver's
-vidioc_reqbufs() callback which, in turn, usually only needs to locate the
-proper struct videobuf_queue pointer and pass it to videobuf_reqbufs().
-These support functions can replace a great deal of buffer management
-boilerplate in a lot of V4L2 drivers.
-
-The vidioc_streamon() and vidioc_streamoff() functions will be a bit more
-complex, of course, since they will also need to deal with starting and
-stopping the capture engine.
-
-Buffer allocation
------------------
-
-Thus far, we have talked about buffers, but have not looked at how they are
-allocated.  The scatter/gather case is the most complex on this front.  For
-allocation, the driver can leave buffer allocation entirely up to the
-videobuf layer; in this case, buffers will be allocated as anonymous
-user-space pages and will be very scattered indeed.  If the application is
-using user-space buffers, no allocation is needed; the videobuf layer will
-take care of calling get_user_pages() and filling in the scatterlist array.
-
-If the driver needs to do its own memory allocation, it should be done in
-the vidioc_reqbufs() function, *after* calling videobuf_reqbufs().  The
-first step is a call to:
-
-.. code-block:: none
-
-    struct videobuf_dmabuf *videobuf_to_dma(struct videobuf_buffer *buf);
-
-The returned videobuf_dmabuf structure (defined in
-<media/videobuf-dma-sg.h>) includes a couple of relevant fields:
-
-.. code-block:: none
-
-    struct scatterlist  *sglist;
-    int                 sglen;
-
-The driver must allocate an appropriately-sized scatterlist array and
-populate it with pointers to the pieces of the allocated buffer; sglen
-should be set to the length of the array.
-
-Drivers using the vmalloc() method need not (and cannot) concern themselves
-with buffer allocation at all; videobuf will handle those details.  The
-same is normally true of contiguous-DMA drivers as well; videobuf will
-allocate the buffers (with dma_alloc_coherent()) when it sees fit.  That
-means that these drivers may be trying to do high-order allocations at any
-time, an operation which is not always guaranteed to work.  Some drivers
-play tricks by allocating DMA space at system boot time; videobuf does not
-currently play well with those drivers.
-
-As of 2.6.31, contiguous-DMA drivers can work with a user-supplied buffer,
-as long as that buffer is physically contiguous.  Normal user-space
-allocations will not meet that criterion, but buffers obtained from other
-kernel drivers, or those contained within huge pages, will work with these
-drivers.
-
-Filling the buffers
--------------------
-
-The final part of a videobuf implementation has no direct callback - it's
-the portion of the code which actually puts frame data into the buffers,
-usually in response to interrupts from the device.  For all types of
-drivers, this process works approximately as follows:
-
- - Obtain the next available buffer and make sure that somebody is actually
-   waiting for it.
-
- - Get a pointer to the memory and put video data there.
-
- - Mark the buffer as done and wake up the process waiting for it.
-
-Step (1) above is done by looking at the driver-managed list_head structure
-- the one which is filled in the buf_queue() callback.  Because starting
-the engine and enqueueing buffers are done in separate steps, it's possible
-for the engine to be running without any buffers available - in the
-vmalloc() case especially.  So the driver should be prepared for the list
-to be empty.  It is equally possible that nobody is yet interested in the
-buffer; the driver should not remove it from the list or fill it until a
-process is waiting on it.  That test can be done by examining the buffer's
-done field (a wait_queue_head_t structure) with waitqueue_active().
-
-A buffer's state should be set to VIDEOBUF_ACTIVE before being mapped for
-DMA; that ensures that the videobuf layer will not try to do anything with
-it while the device is transferring data.
-
-For scatter/gather drivers, the needed memory pointers will be found in the
-scatterlist structure described above.  Drivers using the vmalloc() method
-can get a memory pointer with:
-
-.. code-block:: none
-
-    void *videobuf_to_vmalloc(struct videobuf_buffer *buf);
-
-For contiguous DMA drivers, the function to use is:
-
-.. code-block:: none
-
-    dma_addr_t videobuf_to_dma_contig(struct videobuf_buffer *buf);
-
-The contiguous DMA API goes out of its way to hide the kernel-space address
-of the DMA buffer from drivers.
-
-The final step is to set the size field of the relevant videobuf_buffer
-structure to the actual size of the captured image, set state to
-VIDEOBUF_DONE, then call wake_up() on the done queue.  At this point, the
-buffer is owned by the videobuf layer and the driver should not touch it
-again.
-
-Developers who are interested in more information can go into the relevant
-header files; there are a few low-level functions declared there which have
-not been talked about here.  Note also that all of these calls are exported
-GPL-only, so they will not be available to non-GPL kernel modules.

-视频缓冲辅助函数
----------------
-
-v4l2 核心 API 提供了一个处理视频缓冲的标准方法(称为“videobuf”)。
-这些方法使驱动可以通过统一的方式实现 read()、mmap() 和 overlay()。
-目前在设备上支持视频缓冲的方法有分散/聚集 DMA(videobuf-dma-sg)、
-线性 DMA(videobuf-dma-contig)以及大多用于 USB 设备的用 vmalloc
-分配的缓冲(videobuf-vmalloc)。
-
-请参阅 Documentation/driver-api/media/v4l2-videobuf.rst，以获得更多关于 videobuf
-层的使用信息。

+NPCM video driver
+=================
+
+This driver is used to control the Video Capture/Differentiation (VCD) engine
+and Encoding Compression Engine (ECE) present on Nuvoton NPCM SoCs. The VCD can
+capture a frame from digital video input and compare two frames in memory, and
+the ECE can compress the frame data into HEXTILE format.
+
+Driver-specific Controls
+------------------------
+
+V4L2_CID_NPCM_CAPTURE_MODE
+~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+The VCD engine supports two modes:
+
+- COMPLETE mode:
+
+  Capture the next complete frame into memory.
+
+- DIFF mode:
+
+  Compare the incoming frame with the frame stored in memory, and updates the
+  differentiated frame in memory.
+
+Application can use ``V4L2_CID_NPCM_CAPTURE_MODE`` control to set the VCD mode
+with different control values (enum v4l2_npcm_capture_mode):
+
+- ``V4L2_NPCM_CAPTURE_MODE_COMPLETE``: will set VCD to COMPLETE mode.
+- ``V4L2_NPCM_CAPTURE_MODE_DIFF``: will set VCD to DIFF mode.
+
+V4L2_CID_NPCM_RECT_COUNT
+~~~~~~~~~~~~~~~~~~~~~~~~
+
+If using V4L2_PIX_FMT_HEXTILE format, VCD will capture frame data and then ECE
+will compress the data into HEXTILE rectangles and store them in V4L2 video
+buffer with the layout defined in Remote Framebuffer Protocol:
+::
+
+           (RFC 6143, https://www.rfc-editor.org/rfc/rfc6143.html#section-7.6.1)
+
+           +--------------+--------------+-------------------+
+           | No. of bytes | Type [Value] | Description       |
+           +--------------+--------------+-------------------+
+           | 2            | U16          | x-position        |
+           | 2            | U16          | y-position        |
+           | 2            | U16          | width             |
+           | 2            | U16          | height            |
+           | 4            | S32          | encoding-type (5) |
+           +--------------+--------------+-------------------+
+           |             HEXTILE rectangle data              |
+           +-------------------------------------------------+
+
+Application can get the video buffer through VIDIOC_DQBUF, and followed by
+calling ``V4L2_CID_NPCM_RECT_COUNT`` control to get the number of HEXTILE
+rectangles in this buffer.

Subject: [PATCH 0319/1451] media: nuvoton: Add driver for NPCM video capture
 and encoding engine

Add driver for Video Capture/Differentiation Engine (VCD) and Encoding
Compression Engine (ECE) present on Nuvoton NPCM SoCs. As described in
the datasheet NPCM750D_DS_Rev_1.0, the VCD can capture frames from
digital video input and compare two frames in memory, and then the ECE
can compress the frame data into HEXTILE format. This driver implements
V4L2 interfaces and provides user controls to support KVM feature, also
tested with VNC Viewer ver.6.22.826 and openbmc/obmc-ikvm.

+	  Support for the Video Capture/Differentiation Engine (VCD) and
+	  Encoding Compression Engine (ECE) present on Nuvoton NPCM SoCs.
+	  The VCD can capture a frame from digital video input and compare
+	  two frames in memory, and then the ECE can compress the frame
+	  data into HEXTILE format.

From 5ce19a501673b72cf57ce1908a29a3c5b3cd30bb Mon Sep 17 00:00:00 2001

Subject: [PATCH 0321/1451] media: rc: remove ir-rx51 in favour of generic
 pwm-ir-tx
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The ir-rx51 is a pwm-based TX driver specific to the N900. This can be
handled entirely by the generic pwm-ir-tx driver, and in fact the
pwm-ir-tx driver has been compatible with ir-rx51 from the start.

Note that the suspend code in the ir-rx51 driver is unnecessary, since
during transmit, the process is not in interruptable sleep. The process
is not put to sleep until the transmit completes.

Subject: [PATCH 0326/1451] media: atomisp: sh_css_internal: sh_css_params:
 Unifying sh_css_sp_group data structure

Since some parts of the data structure elements are determined in compile
time, the configuration data structure should be compiled for both two
ISP models. In order to set the configuration for both ISP models in
runtime, The sh_css_sp_group is unified to one data structure for the
configuration to ensure the data structure can be used for both ISP2400
and 2401 in runtime. Also, the unused codes for debug purpose are removed.

Form the aspect of ISP setting, the length and the content of the
configuration structure for ISP2400 and ISP2401 are different. So, we
need to pick up the necessary part of sp_group configuration for both
models and then copy those parts into a temporary buffer. This buffer
is finally written to the ISP with the corresponding length.

Subject: [PATCH 0328/1451] media: atomisp: Clamp width to max 1920 pixels when
 in ATOMISP_RUN_MODE_PREVIEW

The pipeline firmware-binaries used in previed mode have
ia_css_binary_xinfo.output.max_width set to 1920.

This causes ia_css_binary_find() to fail when trying to set a higher
resolution resulting in the dump_stack() call in ia_css_binary_find()
triggering and resulting in the try_fmt() or set_fmt() IOCTL failing.

Fix this by clamping the width to max 1920 when in preview mode.

Change atomisp_enum_framesizes() cut off for too small resolutions
from 2/3th to 5/8th this results in more resolutions being available
with some sensors.

E.g. this allows using 800x600 with a 1280x960 sensor.

Subject: [PATCH 0330/1451] media: atomisp: Add some higher resolutions to
 atomisp_enum_framesizes()

Add some higher resolutions to the fixed list of resolutions which
atomisp_enum_framesizes() uses on sensors which can do cropping and can
thus make any resolution that will fit.

This is useful for higher resolution sensors like the 2560x1920 ov5693
sensor.

Note the highest resolutions added here are 1920x<height> because
the atomisp firmware does not support widths > 1920 with the default
asd->run_mode->val == ATOMISP_RUN_MODE_PREVIEW setting.

Subject: [PATCH 0331/1451] media: atomisp: Remove support for custom run-mode
 v4l2-ctrl on sensors

Remove the support to update a V4L2_CID_RUN_MODE run-mode control
on sensors when changing the atomisp run-mode or directly by calling
the custom ATOMISP_IOC_S_SENSOR_RUNMODE IOCTL.

No sensor drivers implement this and having custom controls / IOCTLs
is undesirable.

Even if there was such a control on sensors then userspace should directly
talk to the sensor v4l2-subdev, rather than relying on a custom IOCTLs
on the output /dev/video# node to pass this through to the senor.

Subject: [PATCH 0332/1451] media: atomisp: Remove
 v4l2_ctrl_s_ctrl(asd->run_mode) calls from atomisp_open()

The v4l2_ctrl_s_ctrl(asd->run_mode) call in atomisp_subdev_init_struct()
gets immediately overridden by a second call directly after
atomisp_subdev_init_struct() is called.

And the second call in atomisp_open() also is not helpful.
ATOMISP_RUN_MODE_PREVIEW is the default and if changed controls
are supposed to stay changed over an open/close of the /dev/video#
node. So drop both calls.

Date: Thu, 13 Jul 2023 12:02:21 +0200
Subject: [PATCH 0333/1451] media: atomisp: ia_css_debug: Removed debug codes
 for dumping status

This portion of debug code was based on a structure for both ISP2400 and
2401 with the same name and controlled by #if defined(ISP2401). This
structure was only used to dump the status of atomisp. So, to make the
driver generic, this part of debug codes can be removed.

From 8fc67b18fa1ccaf8c35919f27ccb119fdc2a35a8 Mon Sep 17 00:00:00 2001
From: Kate Hsuan <hpa@redhat.com>
Date: Thu, 13 Jul 2023 12:02:22 +0200
Subject: [PATCH 0334/1451] media: atomisp: Make two individual enum to define
 the MIPI format

The original mipi_format_t represents the MIPI format settings for both
atomisp with the same name and the enum member was controlled by #if
defined(ISP2401). However, if we want to make this driver generic, this
enum should be individually defined for them.

Since the format type is redefined, the format setting function
ia_css_isys_set_fmt_type() should be reworked for ISP2400 and ISP2401
called ia_css_isys_2400_set_fmt_type() and ia_css_isys_2401_set_fmt_type()
.

Additionally, the function called is_mipi_format_yuv420() isn't used by any
functions so it can be removed.

From 2aea82b03cd4e57f3d639d3bedb0876082416052 Mon Sep 17 00:00:00 2001
From: Kate Hsuan <hpa@redhat.com>
Date: Thu, 13 Jul 2023 12:02:23 +0200
Subject: [PATCH 0335/1451] media: atomisp: Included both input system headers

Included necessary input system header files (local, private, public
scopes) for both types of atomisp. There is also a conflict of
declaration issue so the unused input_system_state_s is removed.

Subject: [PATCH 0341/1451] media: atomisp: Compile the object codes for a

Since a generic driver should support every type of atomisp, all the
codes need to be compiled. The ISP2401 flag controls the Makefile to build
the binary file for ISP2400 and ISP2401. Therefore, this section of
Makefile should be removed allowing all the necessary codes can be built.
Moreover, some parts of "removing #ifdef ISP2401" works are related to it
so they were also removed here.

Subject: [PATCH 0343/1451] media: atomisp: isys_init: Initiate atomisp in a
 generic manner

The original implementation distinguishes and initiates atomisp during
compiler time. This commit allows isys_init to initiate isys for both types
of atomisp in a generic manner.

Subject: [PATCH 0345/1451] media: atomisp: Remove aliases for
 MIPI_FORMAT_2400_CUSTOM0

isp2400_input_system_local.h defines 2 aliases for MIPI_FORMAT_2400_CUSTOM0
MIPI_FORMAT_JPEG, which is entirely unused and MIPI_FORMAT_BINARY_8 which
is used once in ia_css_isys_2400_set_fmt_type().

Drop these aliases and directly use MIPI_FORMAT_2400_CUSTOM0 in
ia_css_isys_2400_set_fmt_type().

Subject: [PATCH 0355/1451] media: atomisp: sh_css: Renamed
 sh_css_config_input_network()

sh_css_config_input_network() is renamed to
sh_css_config_input_network_2400() and sh_css_config_input_network_2401()
since a generic driver should cover the implementation for both types.

Subject: [PATCH 0358/1451] media: atomisp: atomisp_v4l2: Removed unnecessary
 code

Here is the last step of #ifdef ISP2401 removal work. Since the driver
became generic, this part of the code was no longer needed and can
be removed.

Subject: [PATCH 0359/1451] media: atomisp: Simplify some if (IS_ISP2401...)
 statements

Replace:

 if (!IS_ISP2401 || (IS_ISP2401 && xxx))

with:

 if (!IS_ISP2401 || xxx)

If the right side of the '||' needs to be evaluated then it is
already known that IS_ISP2401 is true, so no need to check for it.

Subject: [PATCH 0360/1451] media: atomisp: Drop ia_css_debug_dump_debug_info()
 and functions only used by it

ia_css_debug_dump_debug_info() is defined but never called anywhere,
drop it.

Also drop all the other ia_css_debug_dump_* functions only called by
ia_css_debug_dump_debug_info(), as well as *_get_state() functions only
used by those.

Subject: [PATCH 0361/1451] media: atomisp: Drop VIDEO_ATOMISP_ISP2401 Kconfig
 option

Drop the VIDEO_ATOMISP_ISP2401 Kconfig option and the -DISP2401
cflags.

This is no longer necessary since all ISP2400 vs ISP2401 differences
are now dealt with at runtime.

Many thanks to Kate Hsuan for all her work on this.

 2. Items which SHOULD also be fixed eventually:
 
-* Remove VIDEO_ATOMISP_ISP2401, making the driver to auto-detect the
-  register address differences between ISP2400 and ISP2401
-
 * The driver is intended to drive the PCI exposed versions of the device.
   It will not detect those devices enumerated via ACPI as a field of the
   i915 GPU driver (only a problem on BYT).

Subject: [PATCH 0363/1451] media: atomisp: Disable VCM for OV5693 for now

ov5693 sensor modules have a VCM, but for unknown reasons
the sensor fails to start streaming when instantiating
a VCM i2c-client (and the runtime-pm link between VCM
and sensor).

Disable the VCM for now, until this is resolved.

After recent improvements to atomisp driver, the atomisp driver
now works fine with the standard ov5693 driver.

Drop the no longer necessary atomisp specific atomisp-ov5693
sensor driver.

Just show the Camera index as input name in VIDIOC_ENUM_INPUT,
no need to show the subdev name as well as that is meaningless for

Don't rely on a define, let the compiler use the actual
field size.

Remove all uses of the V4L2_SUBDEV_NAME_SIZE define and also
drop the define itself.

Subject: [PATCH 0379/1451] media: v4l2-device.h: drop V4L2_DEVICE_NAME_SIZE

Don't use defines for the size of a name field, everyone
should just use sizeof(). In this case it was never used,
but it is bad practice, so just drop it.

Subject: [PATCH 0389/1451] memblock: report failures when memblock_can_resize
 is not set

The callers of memblock_reserve() do not check the return value
presuming that memblock_reserve() always succeeds, but there are
cases where it may fail.

Having numerous memblock reservations at early boot where
memblock_can_resize is unset may exhaust the INIT_MEMBLOCK_REGIONS sized
memblock.reserved regions array and an attempt to double this array via
memblock_double_array() will fail and will return -1 to the caller.

When this happens the system crashes anyway, but it's hard to identify
the reason for the crash.

Add a panic message to memblock_double_array() to aid debugging of the
cases when too many regions are reserved before memblock can resize
memblock.reserved array.

Let's use memcpy() as the bounds have already been checked and this
decays into a simple byte copy from one buffer to another removing any
ambiguity that strncpy has.

 __counted_by

Prepare for the coming implementation by GCC and Clang of the __counted_by
attribute. Flexible array members annotated with __counted_by can have
their accesses bounds-checked at run-time checking via CONFIG_UBSAN_BOUNDS
(for array indexing) and CONFIG_FORTIFY_SOURCE (for strcpy/memcpy-family
functions).

As found with Coccinelle[1], add __counted_by for struct evdev_client.

Subject: [PATCH 0393/1451] Input: leds - annotate struct input_leds with
 __counted_by

Prepare for the coming implementation by GCC and Clang of the __counted_by
attribute. Flexible array members annotated with __counted_by can have
their accesses bounds-checked at run-time checking via CONFIG_UBSAN_BOUNDS
(for array indexing) and CONFIG_FORTIFY_SOURCE (for strcpy/memcpy-family
functions).

As found with Coccinelle[1], add __counted_by for struct input_leds.

Subject: [PATCH 0395/1451] Input: axp20x-pek - avoid needless newline removal

This code is doing more work than it needs to.

Before handing off `val_str` to `kstrtouint()` we are eagerly removing
any trailing newline which requires copying `buf`, validating it's
length and checking/replacing any potential newlines.

kstrtouint() handles this implicitly:
kstrtouint ->
  kstrotoull -> (documentation)
|   /**
|    * kstrtoull - convert a string to an unsigned long long
|    * @s: The start of the string. The string must be null-terminated, and may also
|    *  include a single newline before its terminating null. The first character
|    ...

Let's remove the redundant functionality and let kstrtouint handle it.

Subject: [PATCH 0396/1451] iommu: Allow .iotlb_sync_map to fail and handle
 s390's -ENOMEM return

On s390 when using a paging hypervisor, .iotlb_sync_map is used to sync
mappings by letting the hypervisor inspect the synced IOVA range and
updating a shadow table. This however means that .iotlb_sync_map can
fail as the hypervisor may run out of resources while doing the sync.
This can be due to the hypervisor being unable to pin guest pages, due
to a limit on mapped addresses such as vfio_iommu_type1.dma_entry_limit
or lack of other resources. Either way such a failure to sync a mapping
should result in a DMA_MAPPING_ERROR.

Now especially when running with batched IOTLB flushes for unmap it may
be that some IOVAs have already been invalidated but not yet synced via
.iotlb_sync_map. Thus if the hypervisor indicates running out of
resources, first do a global flush allowing the hypervisor to free
resources associated with these mappings as well a retry creating the
new mappings and only if that also fails report this error to callers.

From c76c067e488ccd55734c3e750799caf2c5956db6 Mon Sep 17 00:00:00 2001

Subject: [PATCH 0398/1451] s390/pci: Use dma-iommu layer

While s390 already has a standard IOMMU driver and previous changes have
added I/O TLB flushing operations this driver is currently only used for
user-space PCI access such as vfio-pci. For the DMA API s390 instead
utilizes its own implementation in arch/s390/pci/pci_dma.c which drives
the same hardware and shares some code but requires a complex and
fragile hand over between DMA API and IOMMU API use of a device and
despite code sharing still leads to significant duplication and
maintenance effort. Let's utilize the common code DMAP API
implementation from drivers/iommu/dma-iommu.c instead allowing us to
get rid of arch/s390/pci/pci_dma.c.

Subject: [PATCH 0399/1451] iommu/s390: Disable deferred flush for ISM devices

ISM devices are virtual PCI devices used for cross-LPAR communication.
Unlike real PCI devices ISM devices do not use the hardware IOMMU but
inspects IOMMU translation tables directly on IOTLB flush (s390 RPCIT
instruction).

ISM devices keep their DMA allocations static and only very rarely DMA
unmap at all. For each IOTLB flush that occurs after unmap the ISM
devices will however inspect the area of the IOVA space indicated by the
flush. This means that for the global IOTLB flushes used by the flush
queue mechanism the entire IOVA space would be inspected. In principle
this would be fine, albeit potentially unnecessarily slow, it turns out
however that ISM devices are sensitive to seeing IOVA addresses that are
currently in use in the IOVA range being flushed. Seeing such in-use
IOVA addresses will cause the ISM device to enter an error state and
become unusable.

Fix this by claiming IOMMU_CAP_DEFERRED_FLUSH only for non-ISM devices.
This makes sure IOTLB flushes only cover IOVAs that have been unmapped
and also restricts the range of the IOTLB flush potentially reducing
latency spikes.

Subject: [PATCH 0400/1451] iommu/dma: Allow a single FQ in addition to per-CPU
 FQs

In some virtualized environments, including s390 paged memory guests,
IOTLB flushes are used to update IOMMU shadow tables. Due to this, they
are much more expensive than in typical bare metal environments or
non-paged s390 guests. In addition they may parallelize poorly in
virtualized environments. This changes the trade off for flushing IOVAs
such that minimizing the number of IOTLB flushes trumps any benefit of
cheaper queuing operations or increased paralellism.

In this scenario per-CPU flush queues pose several problems. Firstly
per-CPU memory is often quite limited prohibiting larger queues.
Secondly collecting IOVAs per-CPU but flushing via a global timeout
reduces the number of IOVAs flushed for each timeout especially on s390
where PCI interrupts may not be bound to a specific CPU.

Let's introduce a single flush queue mode that reuses the same queue
logic but only allocates a single global queue. This mode is selected by
dma-iommu if a newly introduced .shadow_on_flush flag is set in struct
dev_iommu. As a first user the s390 IOMMU driver sets this flag during
probe_device. With the unchanged small FQ size and timeouts this setting
is worse than per-CPU queues but a follow up patch will make the FQ size
and timeout variable. Together this allows the common IOVA flushing code
to more closely resemble the global flush behavior used on s390's
previous internal DMA API implementation.

Subject: [PATCH 0401/1451] iommu/dma: Use a large flush queue and timeout for
 shadow_on_flush

Flush queues currently use a fixed compile time size of 256 entries.
This being a power of 2 allows the compiler to use shift and mask
instead of more expensive modulo operations. With per-CPU flush queues
larger queue sizes would hit per-CPU allocation limits, with a single
flush queue these limits do not apply however. Also with single queues
being particularly suitable for virtualized environments with expensive
IOTLB flushes these benefit especially from larger queues and thus fewer
flushes.

To this end re-order struct iova_fq so we can use a dynamic array and
introduce the flush queue size and timeouts as new options in the
iommu_dma_options struct. So as not to lose the shift and mask
optimization, use a power of 2 for the length and use explicit shift and
mask instead of letting the compiler optimize this.

A large queue size and 1 second timeout is then set for the shadow on
flush case set by s390 paged memory guests. This then brings performance
on par with the previous s390 specific DMA API implementation.

Subject: [PATCH 0402/1451] gfs2: ignore negated quota changes

When lots of quota changes are made, there may be cases in which an
inode's quota information is increased and then decreased, such as when
blocks are added to a file, then deleted from it. If the timing is
right, function do_qc can add pending quota changes to a transaction,
then later, another call to do_qc can negate those changes, resulting
in a net gain of 0. The quota_change information is recorded in the qc
buffer (and qd element of the inode as well). The buffer is added to the
transaction by the first call to do_qc, but a subsequent call changes
the value from non-zero back to zero. At that point it's too late to
remove the buffer_head from the transaction. Later, when the quota sync
code is called, the zero-change qd element is discovered and flagged as
an assert warning. If the fs is mounted with errors=panic, the kernel
will panic.

This is usually seen when files are truncated and the quota changes are
negated by punch_hole/truncate which uses gfs2_quota_hold and
gfs2_quota_unhold rather than block allocations that use gfs2_quota_lock
and gfs2_quota_unlock which automatically do quota sync.

This patch solves the problem by adding a check to qd_check_sync such
that net-zero quota changes already added to the transaction are no
longer deemed necessary to be synced, and skipped.

In this case references are taken for the qd and the slot from do_qc
so those need to be put. The normal sequence of events for a normal
non-zero quota change is as follows:

gfs2_quota_change
   do_qc
      qd_hold
      slot_hold

Later, when the changes are to be synced:

gfs2_quota_sync
   qd_fish
      qd_check_sync
         gets qd ref via lockref_get_not_dead
   do_sync
      do_qc(QC_SYNC)
         qd_put
	    lockref_put_or_lock
   qd_unlock
      qd_put
         lockref_put_or_lock

In the net-zero change case, we add a check to qd_check_sync so it puts
the qd and slot references acquired in gfs2_quota_change and skip the
unneeded sync.

Subject: [PATCH 0403/1451] gfs2: fix an oops in gfs2_permission

In RCU mode, we might race with gfs2_evict_inode(), which zeroes
->i_gl.  Freeing of the object it points to is RCU-delayed, so
if we manage to fetch the pointer before it's been replaced with
NULL, we are fine.  Check if we'd fetched NULL and treat that
as "bail out and tell the caller to get out of RCU mode".

Subject: [PATCH 0404/1451] iommu: Do not use IOMMU_DOMAIN_DMA if
 CONFIG_IOMMU_DMA is not enabled

msm_iommu platforms do not select either CONFIG_IOMMU_DMA or
CONFIG_ARM_DMA_USE_IOMMU so they create a IOMMU_DOMAIN_DMA domain by
default and never populate it. This acts like a BLOCKED domain and breaks
the GPU driver on the platform.

Detect this and force use of IDENTITY instead.

Subject: [PATCH 0405/1451] s390/pci: Fix reset of IOMMU software counters

Together with enabling the Function Measurement Block
zpci_fmb_enable_device() also resets the software counters. This allows
to use "echo 0 > /sys/kernel/debug/pci/<dev>/statistics" followed by
echo "1 > /../statistics" to reset all counters. In commit c76c067e488c
("s390/pci: Use dma-iommu layer") this use of the now obsolete counters
in struct zpci_device was missed as was their removal. Fix this by
resetting the new counters and removing the old ones.

Subject: [PATCH 0417/1451] iommu/amd: Remove iommu_v2 module

AMD GPU driver which was the only in-kernel user of iommu_v2 module
removed dependency on iommu_v2 module.

Also we are working on adding SVA support in AMD IOMMU driver. Device
drivers are expected to use common SVA framework to enable device
PASID/PRI features.

Removing iommu_v2 module and then adding SVA simplifies the development.
Hence remove iommu_v2 module.

Subject: [PATCH 0421/1451] Revert "iommu: Fix false ownership failure on AMD
 systems with PASID activated"

This reverts commit 2380f1e8195ef612deea1dc7a3d611c5d2b9b56a.

Previous patch removed AMD iommu_v2 module. Hence its safe to revert this
workaround.

Subject: [PATCH 0422/1451] powerpc/iommu: Do not do platform domain attach
 atctions after probe

POWER throws a splat at boot, it looks like the DMA ops were probably
changed while a driver was attached. Something is still weird about how
power sequences its bootup. Previously this was hidden since the core
iommu code did nothing during probe, now it calls
spapr_tce_platform_iommu_attach_dev().

Make spapr_tce_platform_iommu_attach_dev() do nothing on the probe time
call like it did before.

 driver
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Digiteq Automotive MGB4 is a modular frame grabber PCIe card for automotive
video interfaces. As for now, two modules - FPD-Link and GMSL - are
available and supported by the driver. The card has two inputs and two
outputs (FPD-Link only).

In addition to the video interfaces it also provides a trigger signal
interface and a MTD interface for FPGA firmware upload.

+====================
+mgb4 sysfs interface
+====================
+
+The mgb4 driver provides a sysfs interface, that is used to configure video
+stream related parameters (some of them must be set properly before the v4l2
+device can be opened) and obtain the video device/stream status.
+
+There are two types of parameters - global / PCI card related, found under
+``/sys/class/video4linux/videoX/device`` and module specific found under
+``/sys/class/video4linux/videoX``.
+
+
+Global (PCI card) parameters
+============================
+
+**module_type** (R):
+    Module type.
+
+    | 0 - No module present
+    | 1 - FPDL3

+
+**fw_type** (R):
+    Firmware type.
+
+    | 1 - FPDL3
+    | 2 - GMSL
+
+**fw_version** (R):
+    Firmware version number.
+
+**serial_number** (R):
+    Card serial number. The format is::
+
+        PRODUCT-REVISION-SERIES-SERIAL
+
+    where each component is a 8b number.
+

+
+**stream_status** (R):

+    field of the v4l2_bt_timings struct.
+
+**video_height** (R):

+    | 2 - not available
+
+**vsync_gap_length** (RW):

+    internal HSYNC pulse. The value must be greater than 1 and smaller than
+    vsync_gap_length.
+
+**pclk_frequency** (R):
+    Input pixel clock frequency in kHz.
+
+    The value is identical to what VIDIOC_QUERY_DV_TIMINGS returns in

+    the vbackporch field of the v4l2_bt_timings struct.
+
+**vfront_porch** (R):

+    "dual".
+
+    | 0 - PLL < 50MHz (default)
+    | 1 - PLL >= 50MHz
+
+    *Note: This parameter can not be changed while the input v4l2 device is

+
+
+Common FPDL3/GMSL output parameters
+===================================
+
+**output_id** (R):
+    Output number ID, zero based.
+
+**video_source** (RW):
+    Output video source. If set to 0 or 1, the source is the corresponding card
+    input and the v4l2 output devices are disabled. If set to 2 or 3, the source
+    is the corresponding v4l2 video output device. The default is
+    the corresponding v4l2 output, i.e. 2 for OUT1 and 3 for OUT2.
+
+    | 0 - input 0
+    | 1 - input 1
+    | 2 - v4l2 output 0
+    | 3 - v4l2 output 1
+
+    *Note: This parameter can not be changed while ANY of the input/output v4l2
+    devices is open.*
+
+**display_width** (RW):
+    Display width. There is no autodetection of the connected display, so the
+    proper value must be set before the start of streaming. The default width
+    is 1280.
+
+    *Note: This parameter can not be changed while the output v4l2 device is
+    open.*
+
+**display_height** (RW):
+    Display height. There is no autodetection of the connected display, so the
+    proper value must be set before the start of streaming. The default height
+    is 640.
+
+    *Note: This parameter can not be changed while the output v4l2 device is
+    open.*

+    DE signal polarity.
+
+    | 0 - active low

+
+**pclk_frequency** (RW):
+    Output pixel clock frequency. Allowed values are between 25000-190000(kHz)
+    and there is a non-linear stepping between two consecutive allowed
+    frequencies. The driver finds the nearest allowed frequency to the given
+    value and sets it. When reading this property, you get the exact
+    frequency set by the driver. The default frequency is 70000kHz.
+
+    *Note: This parameter can not be changed while the output v4l2 device is
+    open.*
+
+**hsync_width** (RW):
+    Width of the HSYNC signal in pixels. The default value is 16.
+
+**vsync_width** (RW):

+
+**fpdl3_input_width** (RW):
+    Number of deserializer input lines.
+
+    | 0 - auto (default)
+    | 1 - single
+    | 2 - dual
+
+FPDL3 specific output parameters

+    The GMSL multi-stream contains up to four video streams. This parameter
+    selects which stream is captured by the video input. The value is the
+    zero-based index of the stream. The default stream id is 0.
+
+    *Note: This parameter can not be changed while the input v4l2 device is
+    open.*
+
+**gmsl_fec** (RW):
+    GMSL Forward Error Correction (FEC).
+
+    | 0 - disabled
+    | 1 - enabled (default)
+
+
+====================
+mgb4 mtd partitions
+====================
+
+The mgb4 driver creates a MTD device with two partitions:
+ - mgb4-fw.X - FPGA firmware.
+ - mgb4-data.X - Factory settings, e.g. card serial number.
+
+The *mgb4-fw* partition is writable and is used for FW updates, *mgb4-data* is
+read-only. The *X* attached to the partition name represents the card number.
+Depending on the CONFIG_MTD_PARTITIONED_MASTER kernel configuration, you may
+also have a third partition named *mgb4-flash* available in the system. This
+partition represents the whole, unpartitioned, card's FLASH memory and one should
+not fiddle with it...
+
+====================
+mgb4 iio (triggers)
+====================
+
+The mgb4 driver creates an Industrial I/O (IIO) device that provides trigger and
+signal level status capability. The following scan elements are available:
+
+**activity**:
+	The trigger levels and pending status.
+
+	| bit 1 - trigger 1 pending
+	| bit 2 - trigger 2 pending
+	| bit 5 - trigger 1 level
+	| bit 6 - trigger 2 level
+
+**timestamp**:
+	The trigger event timestamp.
+
+The iio device can operate either in "raw" mode where you can fetch the signal
+levels (activity bits 5 and 6) using sysfs access or in triggered buffer mode.
+In the triggered buffer mode you can follow the signal level changes (activity
+bits 1 and 2) using the iio device in /dev. If you enable the timestamps, you
+will also get the exact trigger event time that can be matched to a video frame
+(every mgb4 video frame has a timestamp with the same clock source).
+
+*Note: although the activity sample always contains all the status bits, it makes
+no sense to get the pending bits in raw mode or the level bits in the triggered
+buffer mode - the values do not represent valid data in such case.*

Subject: [PATCH 0425/1451] media: qcom: camss: Amalgamate struct resource with
 struct resource_ispif

There is no good reason to differentiate the two resource structures
here. As part of a general tidyup of the declaration and passing of
resources within in the CAMSS driver it will be advantageous to have
one unified resource structure.

The two structures are very similar anyway thus leading more credence
still to the argument there should be only one.

Subject: [PATCH 0426/1451] media: qcom: camss: Rename camss struct resources
 to camss_subdev_resources

Rename non-specific struct resources {} to struct camss_subdev_resources {}

Each logical block in CAMSS has a number of regulators, clocks and resets
associated with it. We represent these blocks as v4l subdevices.

The name "struct camss_subdev_resources" is a more descriptive and accurate
name.

Subject: [PATCH 0427/1451] media: qcom: camss: Start to move to module compat
 matched resources

There is a lot of unnecessary if/elsing in this code that arguably
should never have made it upstream when adding a second let alone
subsequent SoC.

I'm guilty of not fixing the mess myself when adding in the sm8250.
Before adding in any new SoCs or resources lets take the time to cleanup
the resource passing.

First step is to pass the generic struct camss_resources as a parameter
per the compatible list.

Subsequent patches will address the other somewhat disparate strutures
which we are also doing if/else on and assigning statically.

Squashed down a commit to drop useless NULL assignment for ispif resources.

From 5900b051959ebf56eb5c6687d8cafb48fc34b973 Mon Sep 17 00:00:00 2001
From: Bryan O'Donoghue <bryan.odonoghue@linaro.org>
Date: Mon, 25 Sep 2023 16:46:55 +0100
Subject: [PATCH 0429/1451] media: qcom: camss: Pass remainder of variables as
 resources

The following variables are being assigned statically based on
compatible strings in the probe path.

* enum camss_version version;
* unsigned int csiphy_num;
* unsigned int csid_num;
* unsigned int vfe_num;
* unsigned int vfe_lite_num;
* unsigned int vfe_total_num;

Migrate those variables to resource parameters passed in on platform
probe arguments. The one caveat is for VFE it has been necessary to
intoduce a new variable vfe_total_num to capture the aggregate value of
vfe_num + vfe_lite_num.

All the rest of the changes are rote camss->variable to
camss->res->variable with the parameter tables now populating the listed
variables.

From 91719b27926a2e382dba8cb161cb244aebddad71 Mon Sep 17 00:00:00 2001

Subject: [PATCH 0430/1451] media: qcom: camss: Pass line_num from compat
 resources

line_num indicates the number of RDI - raw data interface channels which
are associated with a given IFE/VFE - image/video front end.

On several SoCs the RDI number is not static for each VFE - for example
on sm8250 VFE Lite has four RDIs where regular VFE has three.

Assigning line_num statically in the subdev_init() phase initialises
each VFE to the lower number, meaning in practical terms that we are
lobbing off one RDI on some VFEs.

Interrupt handling uses static for (i = RDI0; i < RDI2; i++) {} in some
of our VFE blocks but this can't work for situations where we have a
mixture of VFE @ 3 RDI and VFE-lite @ 4 RDI blocks.

First step to remediate is to pass line_num from a compat string
controlled data-structure and do so on a per-VFE basis.

Later patches will assign the correct number of RDI blocks per VFE.

Subject: [PATCH 0431/1451] media: qcom: camss: Pass CAMSS subdev callbacks via
 resource ops pointer

It is possible to pass all of the CAMSS subdevice internal operations
pointers from the controlling resources structure with an additional
pointer added to the resources structure.

This allows for the removal of most of the probe-time control structures.

From 7c1340e4c2964d1839c0f9c2e0a4397ab4278b84 Mon Sep 17 00:00:00 2001
From: Bryan O'Donoghue <bryan.odonoghue@linaro.org>

Subject: [PATCH 0432/1451] media: qcom: camss: Assign the correct number of
 RDIs per VFE

Each Video Front End - VFE - has a variable number of Raw Data Interfaces -
RDIs associated with it.

The CAMSS code started from a naive implementation where a fixed define was
used as a control in a for(){} loop iterating through RDIs.

That model scales badly. An attempt was made with  VFE_LINE_NUM_GEN2 and
VFE_LINE_NUM_GEN1 to differentiate between SoCs but, the problem with that
is "gen1" and "gen2" have no meaning in the silicon. There is no fixed
constraint in the silicon between VFE and RDI, it is entirely up to the SoC
designers how many VFEs are populated and how many RDIs to associate with
each VFE.

As an example sdm845 has VFE version 175 and sm8250 VFE version 480.
sdm845 has 2 VFEs with 4 RDIs and 1 VFE Lite with 4 RDIs.
sm8250 has 2 VFEs with 3 RDIs and 2 VFE Lite with 4 RDIs.

Clearly then we need a more granular model to capture the necessary data.

The defines have gone away to be replaced with per-SoC data but, we haven't
populated the parameter data with the real values.

Let's call those values out now

msm8916:
1 x VFE
3 x RDI per VFE (not 4)

msm8996:
2 x VFE
3 x RDI per VFE (not 4)

sdm660:
2 x VFE
3 x RDI per VFE (not 4)

sdm845:
2 x VFE
4 x RDI per VFE (not 3)
1 x VFE Lite
4 x RDI per VFE Lite (not 3)

sm8250:
2 x VFE
3 x RDI per VFE (not 4)
2 x VFE Lite
4 x RDI per VFE Lite

This more complex and correct mapping was not possible prior to passing
values via driver data. Now that we have that change in place we can
correctly map VFEs to RDIs for each VFE.

Subject: [PATCH 0433/1451] media: qcom: camss: Remove special case for VFE
 get/put

From sdm845 onwards we need to ensure the VFE is powered on prior to
switching on the CSID.

Currently the code tests for sdm845, sm8250 and then does get/set. This is
not extensible and it turns out is not necessary either since vfe_get and
vfe_set reference count.

Remove the over-conservative SoC version check.

We have a very convoluted if/else legacy here which needs to be
rationalised to make it more sustainable.

Adding in another Soc or two will make some of these if statements into
increasingly large multi-clause behemoths.

Introduce switches in the obvious places to despaghetiify.

Subject: [PATCH 0435/1451] media: qcom: camss: Allow clocks vfeN vfe_liteN or
 vfe_lite

The number of Video Front End - VFE or Image Front End - IFE supported
with new SoCs can vary both for the full and lite cases.

For example sdm845 has one vfe_lite and two vfe interfaces with the vfe
clock called simply "vfe_lite" with no integer postfix. sc8280xp has four
vfe and four vfe lite blocks.

At the moment we declare vfe_lite0 and vfe_lite1 for sm8250 but never set
those clocks because we don't match the strings.

We need to support the following clock name formats

- vfeN
- vfe_liteN
- vfe_lite

with N being any reasonably sized integer.

There are two sites in this code which need to do the same thing,
constructing and matching strings with the pattern above, so encapsulate
the logic in one function.

Subject: [PATCH 0436/1451] media: qcom: camss: Functionally decompose CSIPHY
 clock lookups

The csiphyX_timer and csiX_phy values need not be hard-coded. We can
functionally decompose the string matching inside of a loop.

Static string values are brittle, difficult to extend and not required
anyway since the camss->res->csiphy_num value informs us of the number
of CSIPHYs and hence the set of potential clocks for a given CSIPHY.

In simple terms if we have five CSIPHYs we can have no more and no less
than five csiphy_timer clocks. Similarly csi_phy core clocks have a 1:1
relationship with the PHY they clock.

Subject: [PATCH 0437/1451] media: qcom: camss: Fix support for setting CSIPHY
 clock name csiphyX

Several of our upstream and soon-to-be upstream SoC CAMSS dtsi declare
csiphyX as opposed to the older clock name csiX_phy.

Right now the CAMSS code will fail to set the csiphyX clock even if we have
declared it in our list of clocks. For sdm845 and sm8250 we appear to "get
away" with this error, however on sc8280xp we don't.

The right approach here is to set the clock when it is declared. If a SoC
doesn't require or a SoC driver implementer doesn't think we need, then the
clock ought to simply be omitted from the clock list.

Include csiphyX in the set of permissible strings which will subsequently
lead to the csiphyX clock being set during csiphy_set_clock_rates() phase.

sdm845 and sm8250 will work with the code as-is so I've omitted this from a
suggested Fixes list.

Subject: [PATCH 0438/1451] media: qcom: camss: Support RDI3 for VFE 17x

Some VFEs have four RDIs apiece. Right now the ISR code has a hard-coded
value which tops-out at RDI2 meaning only three RDIs can be utilised in
practice.

Extend out the various routines in camss-vfe-17x.c to support the higher
RDI count.

Subject: [PATCH 0439/1451] media: qcom: camss: Move vfe_disable into a common
 routine where applicable

We can move vfe_disable() into a common routine in the core VFE file
provided we make wm_stop() a VFE specific callback.

The callback is required to capture the case where VFE 17x currently isn't
VC enabled where as VFE 480 is.

Subject: [PATCH 0440/1451] media: qcom: camss: Propagate vfe_reset error up

A previous patch I had removed the returns from vfe_disable() since we
didn't trap any meaningful errors. Konrad pointed out vfe_reset() could
return an error, which is true.

Trap the vfe_reset() error code and throw it up the callstack.

Subject: [PATCH 0441/1451] media: qcom: camss: Comment CSID dt_id field

Digging into the documentation we find that the DT_ID bitfield is used to
map the six bit DT to a two bit ID code. This value is concatenated to the
VC bitfield to create a CID value. DT_ID is the two least significant bits
of CID and VC the most significant bits.

Originally we set dt_id = vc * 4 in and then subsequently set dt_id = vc.

commit 3c4ed72a16bc ("media: camss: sm8250: Virtual channels for CSID")
silently fixed the multiplication by four which would give a better
value for the generated CID without mentioning what was being done or why.

Next up I haplessly changed the value back to "dt_id = vc * 4" since there
didn't appear to be any logic behind it.

Hans asked what the change was for and I honestly couldn't remember the
provenance of it, so I dug in.

Link: https://lore.kernel.org/linux-arm-msm/edd4bf9b-0e1b-883c-1a4d-50f4102c3924@xs4all.nl/

Add a comment so the next hapless programmer doesn't make this same
mistake.

Subject: [PATCH 0445/1451] media: mtk-jpegenc: Fix bug in JPEG encode quality
 selection

The driver uses the upper-bound approach to decide the target JPEG
encode quality, but there's a logic bug that if the desired quality is
higher than what the driver can support, the driver falls back to using
the worst quality.

Fix the bug by assuming using the best quality in the beginning, and
with trivial refactor to avoid long lines.

Subject: [PATCH 0446/1451] media: i2c: adv7180: Extend match support for OF
 tables

The driver has an OF match table, still, it uses an ID lookup table for
retrieving match data. Currently, the driver is working on the
assumption that an I2C device registered via OF will always match a
legacy I2C device ID. The correct approach is to have an OF device ID
table using i2c_get_match_data() if the devices are registered via OF/ID.

Unify the OF/ID table by using struct adv7180_chip_info as match data for
both these tables and replace the ID lookup table for the match data by
i2c_get_match_data().

While at it, remove the trailing comma in the terminator entry for the OF
table making code robust against (theoretical) misrebases or other similar
things where the new entry goes _after_ the termination without the
compiler noticing.

Drop of_match_ptr() from adv7180_driver and get rid of ugly CONFIG_OF
if check. This slightly increases the size of adv7180_driver on non-OF
system and shouldn't be an issue.

Add mod_devicetable.h include.

It also allows, in case if needed, to enumerate this device via ACPI with
PRP0001 magic.

Subject: [PATCH 0450/1451] media: allegro: Annotate struct
 mcu_msg_push_buffers_internal with __counted_by

Prepare for the coming implementation by GCC and Clang of the __counted_by
attribute. Flexible array members annotated with __counted_by can have
their accesses bounds-checked at run-time checking via CONFIG_UBSAN_BOUNDS
(for array indexing) and CONFIG_FORTIFY_SOURCE (for strcpy/memcpy-family
functions).

As found with Coccinelle[1], add __counted_by for
struct mcu_msg_push_buffers_internal.

Subject: [PATCH 0452/1451] media: tvp541x: Extend match support for OF tables

The driver has an OF match table, still, it uses an ID lookup table for
retrieving match data. Currently, the driver is working on the
assumption that an I2C device registered via OF will always match a
legacy I2C device ID. The correct approach is to have an OF device ID
table using i2c_get_match_data() if the devices are registered via OF/ID.

Unify the OF/ID table by using tvp514x_reg as match data for both
these tables and replace the ID lookup table for the match data by
i2c_get_match_data() and simplifly probe().

While at it, remove the trailing comma in the terminator entry for the OF
table making code robust against (theoretical) misrebases or other similar
things where the new entry goes _after_ the termination without the
compiler noticing.

Subject: [PATCH 0453/1451] media: tvp541x: Drop CONFIG_OF ifdeffery

Drop of_match_ptr() from tvp514x_driver and get rid of ugly CONFIG_OF
if check. This slightly increases the size of tvp514x_driver on non-OF
system and shouldn't be an issue.

Add mod_devicetable.h include.

It also allows, in case if needed, to enumerate this device via ACPI with
PRP0001 magic.

Subject: [PATCH 0456/1451] media: s5p-mfc: Fix potential deadlock on condlock

As &dev->condlock is acquired under irq context along the following
call chain from s5p_mfc_irq(), other acquisition of the same lock
inside process context or softirq context should disable irq avoid double
lock. enc_post_frame_start() seems to be one such function that execute
under process context or softirq context.

<deadlock #1>

enc_post_frame_start()
--> clear_work_bit()
--> spin_loc(&dev->condlock)
<interrupt>
   --> s5p_mfc_irq()
   --> s5p_mfc_handle_frame()
   --> clear_work_bit()
   --> spin_lock(&dev->condlock)

This flaw was found by an experimental static analysis tool I am
developing for irq-related deadlock.

To prevent the potential deadlock, the patch change clear_work_bit()
inside enc_post_frame_start() to clear_work_bit_irqsave().

Subject: [PATCH 0460/1451] media: visl: use canonical ftrace path

The canonical location for the tracefs filesystem is at
/sys/kernel/tracing.

But, from Documentation/trace/ftrace.rst:

  Before 4.1, all ftrace tracing control files were within the debugfs
  file system, which is typically located at /sys/kernel/debug/tracing.
  For backward compatibility, when mounting the debugfs file system,
  the tracefs file system will be automatically mounted at:

  /sys/kernel/debug/tracing

Update the visl decoder driver documentation to use this tracefs path.

Subject: [PATCH 0472/1451] media: i2c: Add driver for onsemi MT9M114 camera
 sensor

The MT9M114 is a CMOS camera sensor that combines a 1296x976 pixel array
with a 10-bit dynamic range together with an internal ISP. The driver
exposes two subdevs, one for the pixel array and one for the ISP (named
IFP for Image Flow Processor). Major supported features are

- Full configuration of analog crop and binning in the pixel array
- Full configuration of scaling in the ISP
- Automatic exposure and white balance
- Manual exposure and analog gain
- Horizontal and vertical flip

Subject: [PATCH 0473/1451] media: i2c: imx219: Convert to CCI register access
 helpers

Use the new common CCI register access helpers to replace the private
register access helpers in the imx219 driver. This simplifies the driver
by reducing the amount of code.

Subject: [PATCH 0476/1451] media: i2c: imx219: Drop IMX219_REG_CSI_LANE_MODE
 from common regs array

The IMX219_REG_CSI_LANE_MODE is configured twice, once with a hardcoded
value in the imx219_common_regs registers array, and once with the value
appropriate for the system in imx219_configure_lanes(). The latter is
enough, drop the former.

Subject: [PATCH 0477/1451] media: i2c: imx219: Fix test pattern window for
 640x480 mode

The 640x480 mode specifies incorrect values for the TP_WINDOW_WIDTH and
TP_WINDOW_HEIGHT registers, which likely got copied from the 1640x1232
mode. They should be identical to the X_OUTPUT_SIZE and Y_OUTPUT_SIZE
registers as for all the other modes, to avoid cropping the test
pattern. Fix them.

Subject: [PATCH 0478/1451] media: i2c: imx219: Set mode registers
 programmatically

Replace the per-mode register arrays with code that sets the same
register values using the mode definitions. This avoids duplicating
information in two different places.

The error check for invalid formats in imx219_set_framefmt() is dropped
as the format is guaranteed to be valid.

Subject: [PATCH 0479/1451] media: i2c: imx219: Merge format and binning
 setting functions

The imx219_set_binning() function sets registers based on the bpp value,
which is computed in imx219_set_framefmt(). As both functions are called
from the same place consecutively, and set registers based on the
selected mode, merge them together to simplify the code.

Subject: [PATCH 0480/1451] media: i2c: imx219: Initialize ycbcr_enc

While the ycbcr_enc field doesn't apply to raw formats, leaving it
uninitialized makes the driver behave in a less deterministic way. Fix
it by picking the default value for the colorspace.

Subject: [PATCH 0483/1451] media: i2c: imx219: Access height from active
 format in imx219_set_ctrl

Use the active format height instead of the mode height in
imx219_set_ctrl(). This prepares for dropping the mode field from the
imx219 structure.

The state is retrieved using v4l2_subdev_get_locked_active_state() as
the subdev active state and the control handler share the same lock.

Subject: [PATCH 0484/1451] media: i2c: imx219: Don't store the current mode in
 the imx219 structure

The mode field of the imx219 structure is only used in
imx219_init_controls(), after the probe function sets it to point to the
default mode. Use the default mode directly when initializing controls,
and drop the mode field from the imx219 structure.

Subject: [PATCH 0485/1451] media: i2c: imx219: Drop IMX219_VTS_* macros

The IMX219_VTS_* macros define default VTS values for the modes
supported by the driver. They are used in a single place, and hinder
readability compared to using the value directly as a decimal number.
Drop them.

Subject: [PATCH 0487/1451] media: i2c: imx219: Remove unneeded goto

Simplify the imx219_set_stream() by removing an unneeded goto statement,
and its corresponding error label. The natural flow of the function is
correct.

While at it, drop a useless comment.

Subject: [PATCH 0488/1451] media: i2c: imx219: Implement .init_cfg() using
 .set_fmt()

Instead of duplicating the logical implemented in the .set_fmt()
operation in .init_cfg(), call .set_fmt() directly. This centralizes the
format and crop rectangle calculations in a single place.

The ccs_create_subdev() function initialises a sub-device in the CCS
driver, including CCS specific needs. Rename it as ccs_init_subdev() as it
better reflects what the function does.

Subject: [PATCH 0500/1451] media: ccs: Obtain media bus formats before
 initialising up sub-devices

The available mbus codes will soon be needed earlier, at the time
sub-devices are initialisaed. This is due to calling init_cfg() op via the
v4l2_subdev_init_finalize().

Move ccs_get_mbus_formats() before ccs_init_subdev() calls.

Subject: [PATCH 0501/1451] media: ccs: Use sub-device active state

Make use of sub-device active state. In most cases the effect on need for
acquiring the mutex is non-existent as access to the driver's core data
structure still needs to be serialised.

This still removes a lot of code as the code paths for active and try
state are the same in many cases.

Subject: [PATCH 0502/1451] media: ccs: Partially revert "media: i2c: Use
 pm_runtime_resume_and_get()"

ccs_pm_get_init() depends on the return values > 0 of
pm_runtime_get_sync(), thus it can't use pm_runtime_resume_and_get().
There's even a comment in the driver on this, a few lines above the code.

Fixes: aa0adb399d09 ("media: i2c: Use pm_runtime_resume_and_get()")

Subject: [PATCH 0503/1451] media: ccs: Drop re-entrant s_stream support

The s_stream is called to enable and to disable streaming on a sub-device.
The caller may only call it to change the state, enabling streaming is not
allowed when it is already disabled, and similarly for disabling
streaming. Remove the check from the CCS driver.

-Frame size
-----------
-
-There are two distinct ways to configure the frame size produced by camera
-sensors.
-
-Freely configurable camera sensor drivers
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-Freely configurable camera sensor drivers expose the device's internal
-processing pipeline as one or more sub-devices with different cropping and
-scaling configurations. The output size of the device is the result of a series
-of cropping and scaling operations from the device's pixel array's size.
-
-An example of such a driver is the CCS driver (see ``drivers/media/i2c/ccs``).
-
-Register list based drivers
-~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-Register list based drivers generally, instead of able to configure the device
-they control based on user requests, are limited to a number of preset
-configurations that combine a number of different parameters that on hardware
-level are independent. How a driver picks such configuration is based on the
-format set on a source pad at the end of the device's internal pipeline.
-
-Most sensor drivers are implemented this way, see e.g.
-``drivers/media/i2c/imx319.c`` for an example.
-
-Frame interval configuration
-----------------------------
-
-There are two different methods for obtaining possibilities for different frame
-intervals as well as configuring the frame interval. Which one to implement
-depends on the type of the device.
-
-Raw camera sensors
-~~~~~~~~~~~~~~~~~~
-
-Instead of a high level parameter such as frame interval, the frame interval is
-a result of the configuration of a number of camera sensor implementation
-specific parameters. Luckily, these parameters tend to be the same for more or
-less all modern raw camera sensors.
-
-The frame interval is calculated using the following equation::
-
-	frame interval = (analogue crop width + horizontal blanking) *
-			 (analogue crop height + vertical blanking) / pixel rate
-
-The formula is bus independent and is applicable for raw timing parameters on
-large variety of devices beyond camera sensors. Devices that have no analogue
-crop, use the full source image size, i.e. pixel array size.
-
-Horizontal and vertical blanking are specified by ``V4L2_CID_HBLANK`` and
-``V4L2_CID_VBLANK``, respectively. The unit of the ``V4L2_CID_HBLANK`` control
-is pixels and the unit of the ``V4L2_CID_VBLANK`` is lines. The pixel rate in
-the sensor's **pixel array** is specified by ``V4L2_CID_PIXEL_RATE`` in the same
-sub-device. The unit of that control is pixels per second.
-
-Register list based drivers need to implement read-only sub-device nodes for the
-purpose. Devices that are not register list based need these to configure the
-device's internal processing pipeline.
-
-The first entity in the linear pipeline is the pixel array. The pixel array may
-be followed by other entities that are there to allow configuring binning,
-skipping, scaling or digital crop :ref:`v4l2-subdev-selections`.
-
-USB cameras etc. devices
-~~~~~~~~~~~~~~~~~~~~~~~~
-
-USB video class hardware, as well as many cameras offering a similar higher
-level interface natively, generally use the concept of frame interval (or frame
-rate) on device level in firmware or hardware. This means lower level controls
-implemented by raw cameras may not be used on uAPI (or even kAPI) to control the
-frame interval on these devices.
-
 Rotation, orientation and flipping
 ----------------------------------
 
-Some systems have the camera sensor mounted upside down compared to its natural
-mounting rotation. In such cases, drivers shall expose the information to
-userspace with the :ref:`V4L2_CID_CAMERA_SENSOR_ROTATION
-<v4l2-camera-sensor-rotation>` control.
-
-Sensor drivers shall also report the sensor's mounting orientation with the
-:ref:`V4L2_CID_CAMERA_SENSOR_ORIENTATION <v4l2-camera-sensor-orientation>`.
-
 Use ``v4l2_fwnode_device_parse()`` to obtain rotation and orientation
 information from system firmware and ``v4l2_ctrl_new_fwnode_properties()`` to
 register the appropriate controls.
 
-Sensor drivers that have any vertical or horizontal flips embedded in the
-register programming sequences shall initialize the V4L2_CID_HFLIP and
-V4L2_CID_VFLIP controls with the values programmed by the register sequences.
-The default values of these controls shall be 0 (disabled). Especially these
-controls shall not be inverted, independently of the sensor's mounting
-rotation.

+Example drivers

+level interface natively, generally use the concept of frame interval (or frame
+rate) on device level in firmware or hardware. This means lower level controls
+implemented by raw cameras may not be used on uAPI (or even kAPI) to control the
+frame interval on these devices.
+
+Rotation, orientation and flipping
+----------------------------------
+
+Some systems have the camera sensor mounted upside down compared to its natural
+mounting rotation. In such cases, drivers shall expose the information to
+userspace with the :ref:`V4L2_CID_CAMERA_SENSOR_ROTATION
+<v4l2-camera-sensor-rotation>` control.
+
+Sensor drivers shall also report the sensor's mounting orientation with the
+:ref:`V4L2_CID_CAMERA_SENSOR_ORIENTATION <v4l2-camera-sensor-orientation>`.
+
+Sensor drivers that have any vertical or horizontal flips embedded in the
+register programming sequences shall initialize the :ref:`V4L2_CID_HFLIP
+<v4l2-cid-hflip>` and :ref:`V4L2_CID_VFLIP <v4l2-cid-vflip>` controls with the
+values programmed by the register sequences. The default values of these
+controls shall be 0 (disabled). Especially these controls shall not be inverted,
+independently of the sensor's mounting rotation.

Subject: [PATCH 0512/1451] media: rc: keymaps: add missing MODULE_DESCRIPTION
 to keymaps

When building the modules 'modpost' warns about missing MODULE_DESCRIPTION.

Since almost none of the rc keymap modules have this, it produces a lot of
warnings.

As a first step to fixing all media modules, add this line to all keymaps.
The description should be a human-readable string describing the remote
or the remote controller that the keymap can be used with.

Note that keymaps/rc-cec.c is actually compiled into the rc-core, so that
is the sole keymap source that didn't need this.

Subject: [PATCH 0513/1451] media: imon: fix access to invalid resource for the
 second interface

imon driver probes two USB interfaces, and at the probe of the second
interface, the driver assumes blindly that the first interface got
bound with the same imon driver.  It's usually true, but it's still
possible that the first interface is bound with another driver via a
malformed descriptor.  Then it may lead to a memory corruption, as
spotted by syzkaller; imon driver accesses the data from drvdata as
struct imon_context object although it's a completely different one
that was assigned by another driver.

This patch adds a sanity check -- whether the first interface is
really bound with the imon driver or not -- for avoiding the problem
above at the probe time.

Subject: [PATCH 0514/1451] staging: media: atomisp: drop check for reentrant
 .s_stream()

The subdev .s_stream() operation shall not be called to start streaming
on an already started subdev, or stop streaming on a stopped subdev.
Remove the check that guards against that condition.

Also fixes a smatch warning:

Subject: [PATCH 0522/1451] watchdog: of_xilinx_wdt: Remove unnecessary clock
 disable call in the remove path

There is a mismatch in axi clock enable and disable calls.
The axi clock is enabled and disabled by the probe function,
then it is again disabled in the remove path.
So observed the call trace while removing the module.
Use the clk_enable() and devm_clk_get_prepared() functions
instead of devm_clk_get_enable() to avoid an extra clock disable
call from the remove path.

 Call trace:
  clk_core_disable+0xb0/0xc0
  clk_disable+0x30/0x4c
  clk_disable_unprepare+0x18/0x30
  devm_clk_release+0x24/0x40
  devres_release_all+0xc8/0x190
  device_unbind_cleanup+0x18/0x6c

Subject: [PATCH 0523/1451] Watchdog: marvell_gti_wdt: Remove redundant
 dev_err_probe() for platform_get_irq()

Since commit 7723f4c5ecdb ("driver core: platform: Add an error message
to platform_get_irq*()"), there is no need to call the dev_err_probe()
function directly to print a custom message when handling an error
from platform_get_irq() function as it is going to display an appropriate
error message in case of a failure.

The data-lanes property maps the logical lane numbers to the physical

its value is the physical lane number. Since one physical lane can only
map to one logical lane, no number in the list should repeat. Add the

The notifier is added to the global notifier list when registered. When
the module is removed, the struct csi2rx_priv in which the notifier is
embedded, is destroyed. As a result the notifier list has a reference to
a notifier that no longer exists. This causes invalid memory accesses
when the list is iterated over. Similar for when the probe fails.
Unregister and clean up the notifier to avoid this.

Some platforms like TI's J721E can have the CSI2RX paired with an
external DPHY. Use the generic PHY framework to configure the DPHY with
the correct link frequency.

This resets the stream state machines and FIFOs, giving them a clean
slate. On J721E if the streams are not reset before starting the
capture, the captured frame gets wrapped around vertically on every run
after the first.

Subject: [PATCH 0535/1451] media: cadence: csi2rx: Fix stream data
 configuration

Firstly, there is no VC_EN bit present in the STREAM_DATA_CFG register.
Bit 31 is part of the VL_SELECT field. Remove it completely.

Secondly, it makes little sense to enable ith virtual channel for ith
stream. Sure, there might be a use-case that demands it. But there might
also be a use case that demands all streams to use the 0th virtual
channel. Prefer this case over the former because it is less arbitrary
and also makes it very clear what the limitations of the current driver
is instead of giving a false impression that multiple virtual channels
are supported.

Subject: [PATCH 0539/1451] media: ti: Add CSI2RX support for J721E

TI's J721E uses the Cadence CSI2RX and DPHY peripherals to facilitate
capture over a CSI-2 bus.

The Cadence CSI2RX IP acts as a bridge between the TI specific parts and
the CSI-2 protocol parts. TI then has a wrapper on top of this bridge
called the SHIM layer. It takes in data from stream 0, repacks it, and
sends it to memory over PSI-L DMA.

This driver acts as the "front end" to V4L2 client applications. It
implements the required ioctls and buffer operations, passes the
necessary calls on to the bridge, programs the SHIM layer, and performs
DMA via the dmaengine API to finally return the data to a buffer
supplied by the application.

Subject: [PATCH 0540/1451] media: dt-bindings: hynix,hi846: Add
 video-interface-devices properties

Allow properties from video-interface-devices.yaml for the SK Hynix Hi-846
sensor.

All properties specified in video-interface-devices.yaml schema are
valid, so make them accepted by changing "additionalProperties: false"
to "unevaluatedProperties: false" at the schema top-level.

Add two properties from video-interface-devices.yaml to the example
to validate the new schema.

Subject: [PATCH 0547/1451] media: ccs: Rework initialising sub-device state

Initialise sub-device state in init_cfg callback using ccs_propagate() to
the extent it covers of the initialisation. This fixes a bug where the
driver configuration was incorrectly initialised.

Subject: [PATCH 0548/1451] media: ccs: Fix a (harmless) lockdep warning

The v4l2_subdev_init_finalize() is a macro that creates an unique lockdep
key and name. As the CCS driver initialises all three of its sub-devices
using the same call site, this creates a lockdep warning. Address it.

Subject: [PATCH 0550/1451] media: rkisp1: resizer: Use V4L2 subdev active
 state

Use the V4L2 subdev active state API to store the active format and crop
rectangle. This simplifies the driver not only by dropping the state
stored in the rkisp1_resizer structure, but also by replacing the
ops_lock with the state lock.

From 2cce0a369dbdb59d806f9c0c3599ff74a864c0f4 Mon Sep 17 00:00:00 2001
From: Laurent Pinchart <laurent.pinchart@ideasonboard.com>
Date: Thu, 26 Jan 2023 03:10:01 +0200
Subject: [PATCH 0551/1451] media: rkisp1: isp: Use V4L2 subdev active state

Use the V4L2 subdev active state API to store the active format and crop
rectangle. This simplifies the driver not only by dropping the state
stored in the rkisp1_isp structure, but also by replacing the ops_lock
with the state lock.

The rkisp1_isp.sink_fmt field needs to be kept, as it is accessed from
the stats interrupt handler. To simplify the rkisp1_isp_set_sink_fmt()
implementation, the field is now set when starting the ISP, instead of
when setting the format.

From c7e26218820786d23d999ec9b33c812d07f98199 Mon Sep 17 00:00:00 2001
From: Laurent Pinchart <laurent.pinchart@ideasonboard.com>

Subject: [PATCH 0552/1451] media: rkisp1: csi: Use V4L2 subdev active state

Use the V4L2 subdev active state API to store the active format and crop
rectangle. This simplifies the driver not only by dropping the state
stored in the rkisp1_csi structure, but also by replacing the ops_lock
with the state lock.

Subject: [PATCH 0553/1451] media: rkisp1: Convert hex constants to lowercase

Hex constants in the media subsystem are typically in lowercase. The
rkisp1 driver mostly follows that convention already, except in the
register definitions. Convert all hex constants to lowercase for
consistency.

Subject: [PATCH 0561/1451] media: rkisp1: resizer: Improve debug message when
 configuring resizer

The debug messages that show the resizer configuration are only printed
if the driver enables the resizer. This prevents checking the resizer
configuration when the driver believes it should be disabled. Fix it by
moving the dev_dbg() statements earlier.

Also, combine the two debug prints into a single one to gather all the
information in one place, which makes reading the log easier.

While at it, use %u instead of %d to print unsigned values.

Subject: [PATCH 0562/1451] media: rkisp1: resizer: Fix resizer disable check
 when starting stream

The resizer is used to scale the image, but also to change the
subsampling of YUV formats. Both the luma and chroma dimensions need to
be taken into account to decide whether or not to enable the resizer.
The current implementation disables the resizer if the chroma vertical
size isn't changed, which would be the case when scaling up by a factor
of 2 vertically while at the same time converting from YUV 4:2:2 to
4:2:0. Fix it by checking the luma sizes too.

While at it, reflow and clarify comments in the function.

Subject: [PATCH 0563/1451] media: i2c: adp1653: don't reuse the same node

The child device_node pointer was used for two different children.
This confused smatch, causing this warning:

drivers/media/i2c/adp1653.c:444 adp1653_of_init() warn: missing unwind goto?

Use two different pointers, one for each child node, and add separate
goto labels for each node as well. This also improves error logging
since it will now state for which node the property was missing.

Subject: [PATCH 0568/1451] iommu/arm-smmu-v3: Move ctx_desc out of s1_cfg

arm_smmu_s1_cfg (and by extension arm_smmu_domain) owns both a CD table
and the CD inserted into that table's non-pasid CD entry. This limits
arm_smmu_domain's ability to represent non-pasid domains, where multiple
domains need to be inserted into a common CD table. Rather than describing
an STE entry (which may have multiple domains installed into it with
PASID), a domain should describe a single CD entry instead. This is
precisely the role of arm_smmu_ctx_desc. A subsequent commit will also
move the CD table outside of arm_smmu_domain.

Subject: [PATCH 0569/1451] iommu/arm-smmu-v3: Replace s1_cfg with cdtab_cfg

Remove struct arm_smmu_s1_cfg. This is really just a CD table with a
bit of extra information. Move other attributes of the CD table that
were held there into the existing CD table structure, struct
arm_smmu_ctx_desc_cfg, and replace all usages of arm_smmu_s1_cfg with
arm_smmu_ctx_desc_cfg.

For clarity, use the name "cd_table" for the variables pointing to
arm_smmu_ctx_desc_cfg in the new code instead of cdcfg. A later patch
will make this fully consistent.

This is slighlty cleaner: arm_smmu_ctx_desc_cfg is initialized in a
single function instead of having pieces set ahead-of time by its caller.

Subject: [PATCH 0571/1451] iommu/arm-smmu-v3: move stall_enabled to the cd
 table

A domain can be attached to multiple masters with different
master->stall_enabled values. The stall bit of a CD entry should follow
master->stall_enabled and has an inverse relationship with the
STE.S1STALLD bit.

The stall_enabled bit does not depend on any property of the domain, so
move it out of the arm_smmu_domain struct.  Move it to the CD table
struct so that it can fully describe how CD entries should be written to
it.

Subject: [PATCH 0572/1451] iommu/arm-smmu-v3: Refactor write_ctx_desc

Update arm_smmu_write_ctx_desc and downstream functions to operate on
a master instead of an smmu domain. We expect arm_smmu_write_ctx_desc()
to only be called to write a CD entry into a CD table owned by the
master. Under the hood, arm_smmu_write_ctx_desc still fetches the CD
table from the domain that is attached to the master, but a subsequent
commit will move that table's ownership to the master.

Note that this change isn't a nop refactor since SVA will call
arm_smmu_write_ctx_desc in a loop for every master the domain is
attached to despite the fact that they all share the same CD table. This
loop may look weird but becomes necessary when the CD table becomes
per-master in a subsequent commit.

Subject: [PATCH 0573/1451] iommu/arm-smmu-v3: Move CD table to arm_smmu_master

With this change, each master will now own its own CD table instead of
sharing one with other masters attached to the same domain. Attaching a
stage 1 domain installs CD entries into the master's CD table. SVA
writes its CD entries into each master's CD table if the domain is
shared across masters.

Also add the device to the devices list before writing the CD to the
table so that SVA will know that the CD needs to be re-written to this
device's CD table as well if it decides to update the CD's ASID
concurrently with this function.

Subject: [PATCH 0578/1451] iommu/arm-smmu-v3-sva: Remove bond refcount

Always allocate a new arm_smmu_bond in __arm_smmu_sva_bind and remove
the bond refcount since arm_smmu_bond can never be shared across calls
to __arm_smmu_sva_bind.

The iommu framework will not allocate multiple SVA domains for the same
(device/mm) pair, nor will it call set_dev_pasid for a device if a
domain is already attached on the given pasid. There's also a one-to-one
mapping between MM and PASID. __arm_smmu_sva_bind is therefore never
called with the same (device/mm) pair, and so there's no reason to try
and normalize allocations of the arm_smmu_bond struct for a (device/mm)
pair across set_dev_pasid.

Subject: [PATCH 0579/1451] pwm: jz4740: Consistently name driver data "jz"
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Most but not all pointers to driver data are already called "jz":

	$ git grep 'struct jz4740_pwm_chip \*' v6.5-rc1 -- drivers/pwm/pwm-jz4740.c
	v6.5-rc1:drivers/pwm/pwm-jz4740.c:static inline struct jz4740_pwm_chip *to_jz4740(struct pwm_chip *chip)
	v6.5-rc1:drivers/pwm/pwm-jz4740.c:static bool jz4740_pwm_can_use_chn(struct jz4740_pwm_chip *jz,
	v6.5-rc1:drivers/pwm/pwm-jz4740.c:      struct jz4740_pwm_chip *jz = to_jz4740(chip);
	v6.5-rc1:drivers/pwm/pwm-jz4740.c:      struct jz4740_pwm_chip *jz = to_jz4740(chip);
	v6.5-rc1:drivers/pwm/pwm-jz4740.c:      struct jz4740_pwm_chip *jz = to_jz4740(chip);
	v6.5-rc1:drivers/pwm/pwm-jz4740.c:      struct jz4740_pwm_chip *jz4740 = to_jz4740(pwm->chip);
	v6.5-rc1:drivers/pwm/pwm-jz4740.c:      struct jz4740_pwm_chip *jz4740;

Adapt the two variables called "jz4740" to use the same name for
consistency.

Subject: [PATCH 0580/1451] pwm: Manage owner assignment implicitly for drivers
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Instead of requiring each driver to care for assigning the owner member
of struct pwm_ops, handle that implicitly using a macro. Note that the
owner member has to be moved to struct pwm_chip, as the ops structure
usually lives in read-only memory and so cannot be modified.

The upside is that new low level drivers cannot forget the assignment and
save one line each. The pwm-crc driver didn't assign .owner, that's not
a problem in practice though as the driver cannot be compiled as a
module.

 COMPILE_TEST
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The driver compiles just fine as a module. The parent driver's Kconfig
symbol already depends on X86 || COMPILE_TEST, so X86 can just be
dropped from the dependencies allowing compilation on other platforms
than x86.

Subject: [PATCH 0582/1451] pwm: berlin: Put per-channel config into driver
 data
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Instead of allocating extra data in .request() provide the needed memory
in struct berlin_pwm_chip. This reduces the number of allocations. A
side effect is that on suspend and resume the state for all four
channels is always saved and restored. This is easier (and probably
quicker) than looking up the matching pwm_device and checking its
PWMF_REQUESTED bit.

MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Instead of allocating extra data in .request() provide the needed memory
in struct samsung_pwm_chip. This reduces the number of allocations. Even
though now all 5 channel structs are allocated this is probably
outweighed by the reduced overhead to track up to 6 smaller allocations.

Subject: [PATCH 0587/1451] pwm: sti: Reduce number of allocations and drop
 usage of chip_data
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Instead of using one allocation per capture channel, use a single one. Also
store it in driver data instead of chip data.

This has several advantages:

 - driver data isn't cleared when pwm_put() is called
 - Reduces memory fragmentation

Also register the pwm chip only after the per capture channel data is
initialized as the capture callback relies on this initialization and it
might be called even before pwmchip_add() returns.

It would be still better to have struct sti_pwm_compat_data and the
per-channel data struct sti_cpt_ddata in a single memory chunk, but that's
not easily possible because the number of capture channels isn't known yet
when the driver data struct is allocated.

Fixes: e926b12c611c ("pwm: Clear chip_data in pwm_put()")
Reported-by: George Stark <gnstark@sberdevices.ru>
Fixes: c97267ae831d ("pwm: sti: Add PWM capture callback")

Subject: [PATCH 0588/1451] pwm: cros-ec: Put per-channel data into driver data
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Instead of an allocation of a single u16 per channel, allocate them all in
a single chunk which greatly reduces memory fragmentation and also the
overhead to track the allocated memory. Also put the channel data in
driver data where it's cheaper to determine the address (no function call
involved, just a trivial pointer addition).

This also allows to get rid of the request and free callbacks.

The only cost is that the channel data is allocated early, and even for
unused channels.

Content-Transfer-Encoding: 8bit

The semantic of chip_data is a bit surprising as it's cleared when
pwm_put() is called. Also there is a big overlap with the standard driver
data.

All drivers were adapted to not make use of chip_data any more, so it can
go away.

MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

With devm_clk_get_enabled() the call to clk_disable_unprepare() can be
dropped from the error path and the remove callback. With
devm_pwmchip_add() pwmchip_remove() can be dropped. Then the remove
callback is empty and can go away, too.

MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Moving towards adding non-pci support for the driver, move the pci
parts out of the core into their own module. This is partly due to
the module_driver() code only being allowed once in a module and also
to avoid a number of #ifdef if we build a single file in a system
without pci support.

Subject: [PATCH 0593/1451] pwm: dwc: add PWM bit unset in get_state call
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

If we are not in PWM mode, then the output is technically a 50%
output based on a single timer instead of the high-low based on
the two counters. Add a check for the PWM mode in dwc_pwm_get_state()
and if DWC_TIM_CTRL_PWM is not set, then return a 50% cycle.

This may only be an issue on initialisation, as the rest of the
code currently assumes we're always going to have the extended
PWM mode using two counters.

MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8

Most low-level PWM drivers support duty_cycle == period, and so does the
sysfs API. Also polarity can be changed for enabled PWMs since commit
39100ceea79f ("pwm: Switch to the atomic API").

MIME-Version: 1.0

Content-Transfer-Encoding: 8bit

With devm_clk_get_enabled() the call to clk_disable_unprepare() can be
dropped from the error path and the remove callback. With
devm_pwmchip_add() pwmchip_remove() can be dropped. Then the remove
callback is empty and can go away, too.

Also use dev_err_probe() for simplified (and improved) error reporting.

Subject: [PATCH 0596/1451] pwm: bcm2835: Simplify using devm functions
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

With devm_clk_get_enabled() the call to clk_disable_unprepare() can be
dropped from the error path and the remove callback. With
devm_pwmchip_add() pwmchip_remove() can be dropped. Then the remove
callback is empty and can go away, too. With bcm2835_pwm_remove() the only
user of platform_get_drvdata() is gone and so platform_set_drvdata() can
be dropped from .probe(), too.

Also use dev_err_probe() for simplified (and improved) error reporting.

MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Using devm_pwmchip_add() allows to drop pwmchip_remove() from the remove
function which makes this function empty. Then there is no user of
drvdata left and platform_set_drvdata() can be dropped, too.

Further simplify and improve error returning using dev_err_probe().

Subject: [PATCH 0603/1451] pwm: vt8500: Simplify using devm functions
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

With devm_clk_get_prepared() the call to clk_unprepare() can be dropped
from the error path and the remove callback. With devm_pwmchip_add()
pwmchip_remove() can be dropped. Then the remove callback is empty and
can go away, too. With vt8500_pwm_remove() the last user of
platform_get_drvdata() is gone and so platform_set_drvdata() can be
dropped, too.

Also use dev_err_probe() for simplified (and improved) error reporting.

Subject: [PATCH 0604/1451] pwm: samsung: Consistently use the same name for
 driver data
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The driver uses mostly "chip" to name samsung_pwm_chip pointers:

$ git grep -Pho 'samsung_pwm_chip \*[a-zA-Z0-9_]+(*nla:[a-zA-Z0-9_(])' v6.5-rc1 -- drivers/pwm/pwm-samsung.c | sort | uniq -c
     10 samsung_pwm_chip *chip
      6 samsung_pwm_chip *our_chip
      1 samsung_pwm_chip *pwm

However "chip" is supposed to be used for struct pwm_chip pointers and
"pwm" for struct pwm_device pointers. So consistently use "our_chip".

Subject: [PATCH 0605/1451] pwm: cros-ec: Simplify using devm_pwmchip_add() and
 dev_err_probe()
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Using devm_pwmchip_add() allows to drop pwmchip_remove() from the remove
function which makes this function empty. Then there is no user of
drvdata left and platform_set_drvdata() can be dropped, too.

Further simplify and improve error returning using dev_err_probe().

Subject: [PATCH 0606/1451] pwm: pxa: Explicitly include correct DT includes
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The DT of_device.h and of_platform.h date back to the separate
of_platform_bus_type before it as merged into the regular platform bus.
As part of that merge prepping Arm DT support 13 years ago, they
"temporarily" include each other. They also include platform_device.h
and of.h. As a result, there's a pretty much random mix of those include
files used throughout the tree. In order to detangle these headers and
replace the implicit includes with struct declarations, users need to
explicitly include the correct includes.

The suspend/resume functions currently utilize
clk_disable()/clk_enable() respectively which may be no-ops with certain
clock providers such as SCMI. Fix this to use clk_disable_unprepare()
and clk_prepare_enable() respectively as we should.

Subject: [PATCH 0617/1451] Documentation: media: gen-errors.rst: fix confusing
 ENOTTY description

The text is very, very old and predates /dev/mediaX devices, so the
reference to "media device" is today very confusing.

It also says that the ioctl is not supported by the driver, but a
driver may have multiple device nodes, some support a given ioctl,
and some don't.

Simplify the description: ENOTTY means that the ioctl is not supported
by the file descriptor.

When calling debugfs functions, there is no need to ever check the
return value. The function can work or not, but the code logic should
never do something different based on this.

Subject: [PATCH 0621/1451] media: siano: Drop unnecessary error check for
 debugfs_create_dir/file()

Both debugfs_create_dir() and debugfs_create_file() return ERR_PTR
and never return NULL.

As Hans suggested, this patch removes the error checking for both
debugfs_create_dir() and debugfs_create_file() in smsdvb_debugfs_create().
This is because the DebugFS kernel API is developed in a way that the
caller can safely ignore the errors that occur during the creation of
DebugFS nodes. The debugfs APIs have a IS_ERR() judge in start_creating()
which can handle it gracefully. So these checks are unnecessary.

And as Hans pointed out, it's much better to first allocate debug_data
before calling debugfs_create_dir, which need not to clean anything up in
that case.

Subject: [PATCH 0623/1451] media: imx-jpeg: notify source chagne event when
 the first picture parsed

After gstreamer rework the dynamic resolution change handling, gstreamer
stop doing capture buffer allocation based on guesses and wait for the
source change event when available. It requires driver always notify
source change event in the initialization, even if the size parsed is
equal to the size set on capture queue. otherwise, the pipeline will be
stalled.

Currently driver may not notify source change event if the parsed format
and size are equal to those previously established, but it may stall the
gstreamer pipeline.

Prepare for the coming implementation by GCC and Clang of the __counted_by
attribute. Flexible array members annotated with __counted_by can have
their accesses bounds-checked at run-time via CONFIG_UBSAN_BOUNDS (for
array indexing) and CONFIG_FORTIFY_SOURCE (for strcpy/memcpy-family
functions).

As found with Coccinelle[1], add __counted_by for struct ff_device.

Subject: [PATCH 0630/1451] kgdb: Flush console before entering kgdb on panic

When entering kdb/kgdb on a kernel panic, it was be observed that the
console isn't flushed before the `kdb` prompt came up. Specifically,
when using the buddy lockup detector on arm64 and running:
  echo HARDLOCKUP > /sys/kernel/debug/provoke-crash/DIRECT

I could see:
  [   26.161099] lkdtm: Performing direct entry HARDLOCKUP
  [   32.499881] watchdog: Watchdog detected hard LOCKUP on cpu 6
  [   32.552865] Sending NMI from CPU 5 to CPUs 6:

  [   32.872321] NMI backtrace forP cpuANC: Hard LOCKUP

  Entering kdb (current=..., pid 0) on processor 5 due to Keyboard Entry
  [5]kdb>

As you can see, backtraces for the other CPUs start printing and get
interleaved with the kdb PANIC print.

Let's replicate the commands to flush the console in the kdb panic
entry point to avoid this.

 {device, pasid}

Add a debugfs directory per pair of {device, pasid} if the mappings of
its page table are created and destroyed by the iommu_map/unmap()
interfaces. i.e. /sys/kernel/debug/iommu/intel/<device source id>/<pasid>.
Create a debugfs file in the directory for users to dump the page
table corresponding to {device, pasid}. e.g.
/sys/kernel/debug/iommu/intel/0000:00:02.0/1/domain_translation_struct.
For the default domain without pasid, it creates a debugfs file in the
debugfs device directory for users to dump its page table. e.g.
/sys/kernel/debug/iommu/intel/0000:00:02.0/domain_translation_struct.

When setting a domain to a PASID of device, create a debugfs file in
the pasid debugfs directory for users to dump the page table of the
specified pasid. Remove the debugfs device directory of the device
when releasing a device. e.g.
/sys/kernel/debug/iommu/intel/0000:00:01.0

Subject: [PATCH 0634/1451] iommu/vt-d: debugfs: Support dumping a specified
 page table

The original debugfs only dumps all page tables without pasid. With
pasid supported, the page table with pasid also needs to be dumped.

This patch supports dumping a specified page table in legacy mode or
scalable mode with or without a specified pasid.

For legacy mode, according to bus number and DEVFN, traverse the root
table and context table to get the pointer of page table in the
context table entry, then dump the specified page table.

For scalable mode, according to bus number, DEVFN and pasid, traverse
the root table, context table, pasid directory and pasid table to get
the pointer of page table in the pasid table entry, then dump the
specified page table..

Examples are as follows:
1) Dump the page table of device "0000:00:1f.0" that only supports
   legacy mode.
   $ sudo cat
   /sys/kernel/debug/iommu/intel/0000:00:1f.0/domain_translation_struct

2) Dump the page table of device "0000:00:0a.0" with PASID "1" that
   supports scalable mode.
   $ sudo cat
   /sys/kernel/debug/iommu/intel/0000:00:0a.0/1/domain_translation_struct

Subject: [PATCH 0635/1451] iommu/virtio: Add __counted_by for struct
 viommu_request and use struct_size()

Prepare for the coming implementation by GCC and Clang of the __counted_by
attribute. Flexible array members annotated with __counted_by can have
their accesses bounds-checked at run-time via CONFIG_UBSAN_BOUNDS (for
array indexing) and CONFIG_FORTIFY_SOURCE (for strcpy/memcpy-family
functions).

While there, use struct_size() helper, instead of the open-coded
version, to calculate the size for the allocation of the whole
flexible structure, including of course, the flexible-array member.

This code was found with the help of Coccinelle, and audited and
fixed manually.

Subject: [PATCH 0636/1451] iommu: change iommu_map_sgtable to return signed
 values

The iommu_map_sgtable() function returns ssize_t and negative error
codes but it's declared as size_t instead.  I think that static checkers
would have complained if this caused a bug, but even though it doesn't
cause a bug, it's definitely worth fixing.

Subject: [PATCH 0641/1451] drm: renesas: shmobile: Fix overlay plane disable

Merely writing zero to the CHn Source Image Format Register is not
sufficient to disable a plane, as the programmed register value is not
propagated immediately to the current side.  This can be seen when using
the -P option of modetest: the extra plane is displayed correctly, but
does not disappear after exit.

Fix this by doing the full update dance using the Blend Control
Register, like is done when enabling the plane.

Subject: [PATCH 0642/1451] drm: renesas: shmobile: Fix ARGB32 overlay format
 typo

When configuring a CHn Source Image Format Register (LDBBSIFR), one
should use the corresponding LDBBSIFR_RPKF_* definition for overlay
planes, not the DDFR_PKF_* definition for the primary plane.

Fortunately both definitions resolve to the same value, so this bug did
not cause any harm.

Subject: [PATCH 0643/1451] drm: renesas: shmobile: Correct encoder/connector
 types

The first encoder output on the SH-Mobile LCD Controller is a DPI
parallel bus.  However, at the time of introduction of the driver, no
encoder or connector types were defined yet for the DPI parallel bus,
hence the driver used the ones for LVDS instead.

Adjust the types accordingly.

Subject: [PATCH 0644/1451] drm: renesas: shmobile: Add support for Runtime PM

The SH-Mobile LCD Controller is part of a PM Domain on all relevant SoCs
(clock domain on all, power domain on some).  Hence it may not be
sufficient to manage the LCDC module clock explicitly (e.g. if the
selected clock source differs from SHMOB_DRM_CLK_BUS).

Fix this by using Runtime PM for all clock handling.  Add an explicit
dependency on CONFIG_PM, which should already be met on all affected
platforms.

Subject: [PATCH 0648/1451] drm: renesas: shmobile: Improve
 shmob_drm_format_info table

Improve the table containing hardware information related to the
supported plane formats:
  1. Move (part of) the overlay format register settings from multiple
     switch() statements spread across the code into the table, like is
     already done for the primary plane register settings,
  2. Remove the .yuv field, as that information can easily be extracted
     from the register settings using a new helper macro,
  3. Shrink and move the .bpp field to reduce table size.

From: Laurent Pinchart <laurent.pinchart+renesas@ideasonboard.com>
Date: Fri, 15 Sep 2023 10:53:27 +0200
Subject: [PATCH 0649/1451] drm: renesas: shmobile: Remove backlight support

Backlight support should be implemented by panels, not by the LCDC
driver.  As the feature is currently unused anyway, remove it.

Subject: [PATCH 0651/1451] drm: renesas: shmobile: Rename input clocks

Prepare for DT bindings by using more appropriate names for the input
clocks.

Note that all LDDCKR_ICKSEL_* definitions but the one for the bus clock
are valid only for SH7724, so the clock selection code needs to be
updated when extending clock support to other SoCs.

Prepare for DT conversion, where panel probe can be deferred, by
streamlining error propagation and handling:
  - Use dev_err_probe() to avoid printing error messages in case of
    probe deferral,
  - Propagate errors where needed.

Subject: [PATCH 0655/1451] drm: renesas: shmobile: Remove custom plane destroy
 callback

There is no need to call drm_plane_force_disable() from the plane's
.destroy() callback, as the plane should have been disabled already
before.  See also commit 3c858a33858baa8c ("drm/plane_helper: don't
disable plane in destroy function") for the generic plane helper case.

After removing this call, shmob_drm_plane_destroy() becomes a simple
wrapper around shmob_drm_plane_destroy(), hence replace it by the
latter.

Subject: [PATCH 0659/1451] drm: renesas: shmobile: Replace .dev_private with
 container_of()

Now that drm_device is embedded in shmob_drm_device, we can use
a container_of()-based helper to get the shmob_drm_device pointer from
the drm_device, instead of using the deprecated drm_device.dev_private
field.

While at it, restore reverse Xmas tree ordering of local variable
declarations.

 platform data

Replace the drm_mode_modeinfo field with videomode that includes more
signal polarity flags.  This simplifies driver handling of panel modes
and prepares for DT support.

Replace the custom shmob_drm_interface enumeration values with standard
media bus formats.  This simplifies driver handling of bus formats and
prepares for DT support.

Subject: [PATCH 0662/1451] drm: renesas: shmobile: Move interface handling to
 connector setup

Move legacy interface handling to the connector setup code.
Set up bus_flags and bus_formats in display_info according to the
bus format and panel information from platform data, to make it more
similar with DT-based connector/bridge/panel setup.
This will allow us to use the same LCD interface setup code for both
legacy and DT-based systems.

Subject: [PATCH 0663/1451] drm: renesas: shmobile: Unify plane allocation

Unify primary and overlay plane allocation:
  - Enhance shmob_drm_plane_create() so it can be used to create the
    primary plane, too,
  - Move overlay plane creation next to primary plane creation.

Subject: [PATCH 0670/1451] drm: renesas: shmobile: Turn vblank on/off when
 enabling/disabling CRTC

The DRM core vblank handling mechanism requires drivers to forcefully
turn vblank reporting off when disabling the CRTC, and to restore the
vblank reporting status when enabling the CRTC.
Implement this using the drm_crtc_vblank_{on,off}() helpers.

Note that drm_crtc_vblank_off() must be called at startup to synchronize
the state of the vblank core code with the hardware, which is initially
disabled.  This is performed at CRTC creation time, requiring vertical
blank initialization to be moved before creating CRTCs.

    plane handling shared by primary and overlay planes,
  - Adding basic CRTC and mode config atomic mode setting ops, which

Subject: [PATCH 0676/1451] drm: renesas: shmobile: Remove internal CRTC state
 tracking

Now the suspend/resume methods no longer need to look at internal driver
state, the dpms and started fields in the shmob_drm_crtc structure can
be removed, as well as the shmob_drm_crtc_dpms() wrapper.  After this,
shmob_drm_crtc_atomic_{en,dis}able() became just wrappers around
shmob_drm_crtc_st{art,op}(), so inline the latter.

Subject: [PATCH 0678/1451] drm: renesas: shmobile: Add DT support

Add DT support, by:
  1. Creating a panel bridge from DT, and attaching it to the encoder,
  2. Replacing the custom connector with a bridge connector,
  3. Obtaining clock configuration based on the compatible value.

Note that for now the driver uses a fixed clock configuration selecting
the bus clock, as the current code to select other clock inputs needs
changes to support any other SoCs than SH7724.

Set ret to -ENODEV, which seems to be a standard return code when
device_get_match_data() returns NULL.

Subject: [PATCH 0680/1451] xfs: bump max fsgeom struct version

The latest version of the fs geometry structure is v5.  Bump this
constant so that xfs_db and mkfs calls to libxfs_fs_geometry will fill
out all the fields.

IOWs, this commit is a no-op for the kernel, but will be useful for
userspace reporting in later changes.

Subject: [PATCH 0681/1451] xfs: hoist freeing of rt data fork extent mappings

Currently, xfs_bmap_del_extent_real contains a bunch of code to convert
the physical extent of a data fork mapping for a realtime file into rt
extents and pass that to the rt extent freeing function.  Since the
details of this aren't needed when CONFIG_XFS_REALTIME=n, move it to
xfs_rtbitmap.c to reduce code size when realtime isn't enabled.

This will (one day) enable realtime EFIs to reuse the same
unit-converting call with less code duplication.

Quotas aren't (yet) supported with realtime, so we shouldn't allow
userspace to set up a realtime section when quotas are enabled, even if
they attached one via mount options.  IOWS, you shouldn't be able to do:

# mkfs.xfs -f /dev/sda
# mount /dev/sda /mnt -o rtdev=/dev/sdb,usrquota
# xfs_growfs -r /mnt

Subject: [PATCH 0683/1451] xfs: rt stubs should return negative errnos when rt
 disabled

When realtime support is not compiled into the kernel, these functions
should return negative errnos, not positive errnos.  While we're at it,
fix a broken macro declaration.

Subject: [PATCH 0684/1451] xfs: fix units conversion error in
 xfs_bmap_del_extent_delay

The unit conversions in this function do not make sense.  First we
convert a block count to bytes, then divide that bytes value by
rextsize, which is in blocks, to get an rt extent count.  You can't
divide bytes by blocks to get a (possibly multiblock) extent value.

Fortunately nobody uses delalloc on the rt volume so this hasn't
mattered.

Subject: [PATCH 0685/1451] xfs: make sure maxlen is still congruent with prod
 when rounding down

In commit 2a6ca4baed62, we tried to fix an overflow problem in the
realtime allocator that was caused by an overly large maxlen value
causing xfs_rtcheck_range to run off the end of the realtime bitmap.
Unfortunately, there is a subtle bug here -- maxlen (and minlen) both
have to be aligned with @prod, but @prod can be larger than 1 if the
user has set an extent size hint on the file, and that extent size hint
is larger than the realtime extent size.

If the rt free space extents are not aligned to this file's extszhint
because other files without extent size hints allocated space (or the
number of rt extents is similarly not aligned), then it's possible that
maxlen after clamping to sb_rextents will no longer be aligned to prod.
The allocation will succeed just fine, but we still trip the assertion.

Fix the problem by reducing maxlen by any misalignment with prod.  While
we're at it, split the assertions into two so that we can tell which
value had the bad alignment.

Subject: [PATCH 0687/1451] xfs: convert xfs_extlen_t to xfs_rtxlen_t in the rt
 allocator

In most of the filesystem, we use xfs_extlen_t to store the length of a
file (or AG) space mapping in units of fs blocks.  Unfortunately, the
realtime allocator also uses it to store the length of a rt space
mapping in units of rt extents.  This is confusing, since one rt extent
can consist of many fs blocks.

Separate the two by introducing a new type (xfs_rtxlen_t) to store the
length of a space mapping (in units of realtime extents) that would be
found in a file.

Subject: [PATCH 0688/1451] xfs: create a helper to convert rtextents to
 rtblocks

Create a helper to convert a realtime extent to a realtime block.  Later
on we'll change the helper to use bit shifts when possible.

Subject: [PATCH 0691/1451] xfs: convert rt bitmap extent lengths to
 xfs_rtbxlen_t

XFS uses xfs_rtblock_t for many different uses, which makes it much more
difficult to perform a unit analysis on the codebase.  One of these
(ab)uses is when we need to store the length of a free space extent as
stored in the realtime bitmap.  Because there can be up to 2^64 realtime
extents in a filesystem, we need a new type that is larger than
xfs_rtxlen_t for callers that are querying the bitmap directly.  This
means scrub and growfs.

Create this type as "xfs_rtbxlen_t" and use it to store 64-bit rtx
lengths.  'b' stands for 'bitmap' or 'big'; reader's choice.

Subject: [PATCH 0693/1451] xfs: rename xfs_verify_rtext to xfs_verify_rtbext

This helper function validates that a range of *blocks* in the
realtime section is completely contained within the realtime section.
It does /not/ validate ranges of *rtextents*.  Rename the function to
avoid suggesting that it does, and change the type of the @len parameter
since xfs_rtblock_t is a position unit, not a length unit.

Subject: [PATCH 0694/1451] xfs: create helpers to convert rt block numbers to
 rt extent numbers

Create helpers to do unit conversions of rt block numbers to rt extent
numbers.  There are three variations -- one to compute the rt extent
number from an rt block number; one to compute the offset of an rt block
within an rt extent; and one to extract both.

Subject: [PATCH 0695/1451] xfs: convert rt extent numbers to xfs_rtxnum_t

Further disambiguate the xfs_rtblock_t uses by creating a new type,
xfs_rtxnum_t, to store the position of an extent within the realtime
section, in units of rtextents.

Subject: [PATCH 0696/1451] xfs: convert do_div calls to xfs_rtb_to_rtx helper
 calls

Convert these calls to use the helpers, and clean up all these places
where the same variable can have different units depending on where it
is in the function.

Replace these macros with typechecked helper functions.  Eventually
we're going to add more logic to the helpers and it'll be easier if we
don't have to macro it up.

Subject: [PATCH 0699/1451] xfs: use shifting and masking when converting rt
 extents, if possible

Avoid the costs of integer division (32-bit and 64-bit) if the realtime
extent size is a power of two.

Subject: [PATCH 0701/1451] xfs: convert open-coded xfs_rtword_t pointer
 accesses to helper

There are a bunch of places where we use open-coded logic to find a
pointer to an xfs_rtword_t within a rt bitmap buffer.  Convert all that
to helper functions for better type safety.

Subject: [PATCH 0705/1451] xfs: create a helper to handle logging parts of rt
 bitmap/summary blocks

Create an explicit helper function to log parts of rt bitmap and summary
blocks.  While we're at it, fix an off-by-one error in two of the
rtbitmap logging calls that led to unnecessarily large log items but was
otherwise benign.

Note that the upcoming rtgroups patchset will add block headers to the
rtbitmap and rtsummary files.  The helpers in this and the next few
patches take a less than direct route through xfs_rbmblock_wordptr and
xfs_rsumblock_infoptr to avoid helper churn in that patchset.

Subject: [PATCH 0707/1451] xfs: use accessor functions for bitmap words

Create get and set functions for rtbitmap words so that we can redefine
the ondisk format with a specific endianness.  Note that this requires
the definition of a distinct type for ondisk rtbitmap words so that the
compiler can perform proper typechecking as we go back and forth.

In the upcoming rtgroups feature, we're going to fix the problem that
rtwords are written in host endian order, which means we'll need the
distinct rtword/rtword_raw types.

Subject: [PATCH 0710/1451] xfs: use accessor functions for summary info words

Create get and set functions for rtsummary words so that we can redefine
the ondisk format with a specific endianness.  Note that this requires
the definition of a distinct type for ondisk summary info words so that
the compiler can perform proper typechecking.

After commit 411740f5422a ("KVM: MIPS/MMU: Implement KVM_CAP_SYNC_MMU")
old_pte is no longer used in kvm_mips_map_page(). So remove it to fix a
build warning about variable set but not used:

   arch/mips/kvm/mmu.c: In function 'kvm_mips_map_page':

Subject: [PATCH 0712/1451] MIPS: lantiq: Fix pcibios_plat_dev_init() "no
 previous prototype" warning
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

After bbd8810d3998 ("PCI: Remove unused includes and superfluous struct
declaration"), <linux/of_pci.h> no longer includes <linux/pci.h>, which
provides the extern declarations for pcibios_plat_dev_init() and
pcibios_map_irq() via <asm/pci.h>.

This results in these new warnings:

  arch/mips/pci/fixup-lantiq.c:13:5: warning: no previous prototype for 'pcibios_plat_dev_init' [-Wmissing-prototypes]
  arch/mips/pci/fixup-lantiq.c:24:5: warning: no previous prototype for 'pcibios_map_irq' [-Wmissing-prototypes]

Include <linux/pci.h> directly to get these declarations.

Subject: [PATCH 0714/1451] arch: mips: remove ReiserFS from defconfig

ReiserFS has been deprecated for a year and a half, yet is still built
as part of a defconfig kernel.

According to commit eb103a51640e ("reiserfs: Deprecate reiserfs"), the
filesystem is slated to be removed in 2025. Remove it from the defconfig
profiles now, as part of its deprecation process.

AR7 is going to be removed from the Kernel, so remove its type
definition from 8250 code. As with previous removals, I checked with
Debian Code Search that 'PORT_AR7' is not used in userspace.

Subject: [PATCH 0717/1451] vlynq: remove bus driver

There are no users with a vlynq_driver in the Kernel tree. Also, only
the AR7 platform ever initialized a VLYNQ bus, but AR7 is going to be
removed from the Kernel. OpenWRT had some out-of-tree drivers which they
probably intended to upport, but AR7 devices are even there not
supported anymore because they are "stuck with Kernel
3.18" [1]. This code can go.

Subject: [PATCH 0718/1451] watchdog: ar7_wdt: remove driver to prepare for
 platform removal

AR7 is going to be removed from the Kernel, so remove its watchdog
support. This allows us to remove the platform because this driver
includes a platform specific header.

Subject: [PATCH 0719/1451] MIPS: AR7: remove platform

After a discussion about removing VLYNQ support from the Kernel, it was
concluded that its only user, the AR7 platform can go [1]. Even OpenWRT
has removed support because these devices are "stuck with 3.18" [2].

From e94b53ff699c2674a9ec083342a5254866210ade Mon Sep 17 00:00:00 2001
From: Omar Sandoval <osandov@fb.com>

Subject: [PATCH 0720/1451] xfs: cache last bitmap block in realtime allocator

Profiling a workload on a highly fragmented realtime device showed a ton
of CPU cycles being spent in xfs_trans_read_buf() called by
xfs_rtbuf_get(). Further tracing showed that much of that was repeated
calls to xfs_rtbuf_get() for the same block of the realtime bitmap.
These come from xfs_rtallocate_extent_block(): as it walks through
ranges of free bits in the bitmap, each call to xfs_rtcheck_range() and
xfs_rtfind_{forw,back}() gets the same bitmap block. If the bitmap block
is very fragmented, then this is _a lot_ of buffer lookups.

The realtime allocator already passes around a cache of the last used
realtime summary block to avoid repeated reads (the parameters rbpp and
rsb). We can do the same for the realtime bitmap.

This replaces rbpp and rsb with a struct xfs_rtbuf_cache, which caches
the most recently used block for both the realtime bitmap and summary.
xfs_rtbuf_get() now handles the caching instead of the callers, which
requires plumbing xfs_rtbuf_cache to more functions but also makes sure
we don't miss anything.

From 5b1d0ae9753f0654ab56c1e06155b3abf2919d71 Mon Sep 17 00:00:00 2001

Subject: [PATCH 0721/1451] xfs: simplify xfs_rtbuf_get calling conventions

Now that xfs_rtalloc_args holds references to the last-read bitmap and
summary blocks, we don't need to pass the buffer pointer out of
xfs_rtbuf_get.

Callers no longer have to xfs_trans_brelse on their own, though they are
required to call xfs_rtbuf_cache_relse before the xfs_rtalloc_args goes
out of scope.

While we're at it, create some trivial helpers so that we don't have to
remember if "0" means "bitmap" and "1" means "summary".

Subject: [PATCH 0723/1451] xfs: invert the realtime summary cache

In commit 355e3532132b ("xfs: cache minimum realtime summary level"), I
added a cache of the minimum level of the realtime summary that has any
free extents. However, it turns out that the _maximum_ level is more
useful for upcoming optimizations, and basically equivalent for the
existing usage. So, let's change the meaning of the cache to be the
maximum level + 1, or 0 if there are no free extents.

For example, if the cache contains:

{0, 4}

then there are no free extents starting in realtime bitmap block 0, and
there are no free extents larger than or equal to 2^4 blocks starting in
realtime bitmap block 1. The cache is a loose upper bound, so there may
or may not be free extents smaller than 2^4 blocks in realtime bitmap
block 1.

 xfs_rtany_summary()

Instead of only returning whether there is any free space, return the
maximum size, which is fast thanks to the previous commit. This will be
used by two upcoming optimizations.

Subject: [PATCH 0725/1451] xfs: limit maxlen based on available space in
 xfs_rtallocate_extent_near()

xfs_rtallocate_extent_near() calls xfs_rtallocate_extent_block() with
the minlen and maxlen that were passed to it.
xfs_rtallocate_extent_block() then scans the bitmap block looking for a
free range of size maxlen. If there is none, it has to scan the whole
bitmap block before returning the largest range of at least size minlen.
For a fragmented realtime device and a large allocation request, it's
almost certain that this will have to search the whole bitmap block,
leading to high CPU usage.

However, the realtime summary tells us the maximum size available in the
bitmap block. We can limit the search in xfs_rtallocate_extent_block()
to that size and often stop before scanning the whole bitmap block.

Subject: [PATCH 0726/1451] xfs: don't try redundant allocations in
 xfs_rtallocate_extent_near()

xfs_rtallocate_extent_near() tries to find a free extent as close to a
target bitmap block given by bbno as possible, which may be before or
after bbno. Searching backwards has a complication: the realtime summary
accounts for free space _starting_ in a bitmap block, but not straddling
or ending in a bitmap block. So, when the negative search finds a free
extent in the realtime summary, in order to end up closer to the target,
it looks for the end of the free extent. For example, if bbno - 2 has a
free extent, then it will check bbno - 1, then bbno - 2. But then if
bbno - 3 has a free extent, it will check bbno - 1 again, then bbno - 2
again, and then bbno - 3. This results in a quadratic loop, which is
completely pointless since the repeated checks won't find anything new.

Fix it by remembering where we last checked up to and continue from
there. This also obviates the need for a check of the realtime summary.

Subject: [PATCH 0727/1451] xfs: don't look for end of extent further than
 necessary in xfs_rtallocate_extent_near()

As explained in the previous commit, xfs_rtallocate_extent_near() looks
for the end of a free extent when searching backwards from the target
bitmap block. Since the previous commit, it searches from the last
bitmap block it checked to the bitmap block containing the start of the
extent.

This may still be more than necessary, since the free extent may not be
that long. We know the maximum size of the free extent from the realtime
summary. Use that to compute how many bitmap blocks we actually need to
check.

Subject: [PATCH 0728/1451] NFSv4: Add a parameter to limit the number of
 retries after NFS4ERR_DELAY

When using a 'softerr' mount, the NFSv4 client can get stuck waiting
forever while the server just returns NFS4ERR_DELAY. Among other things,
this causes the knfsd server threads to busy wait.
Add a parameter that tells the NFSv4 client how many times to retry
before giving up.

Subject: [PATCH 0735/1451] xfs: handle nimaps=0 from xfs_bmapi_write in
 xfs_alloc_file_space

If xfs_bmapi_write finds a delalloc extent at the requested range, it
tries to convert the entire delalloc extent to a real allocation.

But if the allocator cannot find a single free extent large enough to
cover the start block of the requested range, xfs_bmapi_write will
return 0 but leave *nimaps set to 0.

In that case we simply need to keep looping with the same startoffset_fsb
so that one of the following allocations will eventually reach the
requested range.

Note that this could affect any caller of xfs_bmapi_write that covers
an existing delayed allocation.  As far as I can tell we do not have
any other such caller, though - the regular writeback path uses
xfs_bmapi_convert_delalloc to convert delayed allocations to real ones,
and direct I/O invalidates the page cache first.

Subject: [PATCH 0736/1451] xfs: allow read IO and FICLONE to run concurrently

One of our VM cluster management products needs to snapshot KVM image
files so that they can be restored in case of failure. Snapshotting is
done by redirecting VM disk writes to a sidecar file and using reflink
on the disk image, specifically the FICLONE ioctl as used by
"cp --reflink". Reflink locks the source and destination files while it
operates, which means that reads from the main vm disk image are blocked,
causing the vm to stall. When an image file is heavily fragmented, the
copy process could take several minutes. Some of the vm image files have
50-100 million extent records, and duplicating that much metadata locks
the file for 30 minutes or more. Having activities suspended for such
a long time in a cluster node could result in node eviction.

Clone operations and read IO do not change any data in the source file,
so they should be able to run concurrently. Demote the exclusive locks
taken by FICLONE to shared locks to allow reads while cloning. While a
clone is in progress, writes will take the IOLOCK_EXCL, so they block
until the clone completes.

Subject: [PATCH 0738/1451] gfs2: Stop using GFS2_BASIC_BLOCK and
 GFS2_BASIC_BLOCK_SHIFT

Header gfs2_ondisk.h defines GFS2_BASIC_BLOCK and GFS2_BASIC_BLOCK_SHIFT
in a misguided attempt to abstract away the fact that sectors on block
devices are 512 or (1 << 9) bytes in size.  Stop using those definitions.

I would be inclinded to remove those definitions altogether, but the
gfs2 user-space tools are using them.

In addition, instead of GFS2_SB(inode)->sd_sb.sb_bsize_shift, simply use
inode->i_blkbits.

Subject: [PATCH 0741/1451] media: venus: hfi: add checks to handle
 capabilities from firmware

The hfi parser, parses the capabilities received from venus firmware and
copies them to core capabilities. Consider below api, for example,
fill_caps - In this api, caps in core structure gets updated with the
number of capabilities received in firmware data payload. If the same api
is called multiple times, there is a possibility of copying beyond the max
allocated size in core caps.
Similar possibilities in fill_raw_fmts and fill_profile_level functions.

Subject: [PATCH 0742/1451] media: venus: hfi_parser: Add check to keep the
 number of codecs within range

Supported codec bitmask is populated from the payload from venus firmware.
There is a possible case when all the bits in the codec bitmask is set. In
such case, core cap for decoder is filled  and MAX_CODEC_NUM is utilized.
Now while filling the caps for encoder, it can lead to access the caps
array beyong 32 index. Hence leading to OOB write.
The fix counts the supported encoder and decoder. If the count is more than
max, then it skips accessing the caps.

Subject: [PATCH 0743/1451] media: venus: hfi_cmds: Replace one-element array
 with flex-array member and use __counted_by

Array `data` in `struct hfi_sfr` is being used as a fake flexible array
at run-time:

drivers/media/platform/qcom/venus/hfi_venus.c:
1033         p = memchr(sfr->data, '\0', sfr->buf_size);
1034         /*
1035          * SFR isn't guaranteed to be NULL terminated since SYS_ERROR indicates
1036          * that Venus is in the process of crashing.
1037          */
1038         if (!p)
1039                 sfr->data[sfr->buf_size - 1] = '\0';
1040
1041         dev_err_ratelimited(dev, "SFR message from FW: %s\n", sfr->data);

Fake flexible arrays are deprecated, and should be replaced by
flexible-array members. So, replace one-element array with a
flexible-array member in `struct hfi_sfr`.

While there, also annotate array `data` with __counted_by() to prepare
for the coming implementation by GCC and Clang of the __counted_by
attribute. Flexible array members annotated with __counted_by can have
their accesses bounds-checked at run-time via CONFIG_UBSAN_BOUNDS (for
array indexing) and CONFIG_FORTIFY_SOURCE (for strcpy/memcpy-family
functions).

This results in no differences in binary output.

This issue was found with the help of Coccinelle, and audited and fixed
manually.

Subject: [PATCH 0745/1451] rpmsg: core: Replace deprecated strncpy with
 strscpy

strncpy() is deprecated for use on NUL-terminated destination strings
[1] and as such we should prefer more robust and less ambiguous string
interfaces.

We expect chinfo.name to be NUL-terminated based on its usage with
strncmp():

rpmsg_core.c:
389: if (strncmp(chinfo->name, rpdev->id.name, RPMSG_NAME_SIZE))

Moreover, NUL-padding is not required as chinfo has stack default
initialized all fields to zero:

rpmsg_core.c:
539: struct rpmsg_channel_info chinfo = {};

Considering the above, a suitable replacement is `strscpy` [2] due to
the fact that it guarantees NUL-termination on the destination buffer
without unnecessarily NUL-padding.

Also, favor the more idiomatic strscpy() usage of:
(dest, src, sizeof(dest)).

Since chinfo is not default initialized, we should NUL-pad the `name`

Considering the above, a suitable replacement is `strscpy_pad` due to

Subject: [PATCH 0747/1451] rpmsg: virtio: Replace deprecated strncpy with
 strscpy/_pad

strncpy() is deprecated for use on NUL-terminated destination strings
[1] and as such we should prefer more robust and less ambiguous string
interfaces.

This patch replaces 3 callsites of strncpy().

The first two populate the destination buffer `nsm.name` -- which we
expect to be NUL-terminated based on their use with format strings.

Firstly, as I understand it, virtio_rpmsg_announce_create() creates an
rpmsg_ns_msg and sends via:

virtio_rpmsg_bus.c:
336: err = rpmsg_sendto(rpdev->ept, &nsm, sizeof(nsm), RPMSG_NS_ADDR);

... which uses:
virtio_rpmsg_sendto() -> rpmsg_send_offchannel_raw()

... which copies its data into an rpmsg_hdr `msg` in virtio_rpmsg_bus.c
618: memcpy(msg->data, data, len);

This callback is invoked when a message is received from the remote
processor:

rpmsg_ns.c:
30: /* invoked when a name service announcement arrives */
31: static int rpmsg_ns_cb(struct rpmsg_device *rpdev, void *data, int len,
32: 		       void *priv, u32 src)
33: {
34:         struct rpmsg_ns_msg *msg = data;
...
50:         /* don't trust the remote processor for null terminating the name */
51:         msg->name[RPMSG_NAME_SIZE - 1] = '\0';

... which leads into the use of `name` within a format string:
rpmsg_ns.c:
57: dev_info(dev, "%sing channel %s addr 0x%x\n",
58:          rpmsg32_to_cpu(rpdev, msg->flags) & RPMSG_NS_DESTROY ?
59:          "destroy" : "creat", msg->name, chinfo.dst);

We can also observe that `nsm` is not zero-initialized and as such we
should maintain the NUL-padding behavior that strncpy() provides:

virtio_rpmsg_bus.c:
330: struct rpmsg_ns_msg nsm;

Considering the above, a suitable replacement is `strscpy_pad` due to
the fact that it guarantees both NUL-termination and NUL-padding on the
destination buffer.

Now, for the third and final destination buffer rpdev->id.name we can
just go for strscpy() (not _pad()) as rpdev points to &vch->rpdev:
|       rpdev = &vch->rpdev;

... and vch is zero-allocated:
|       vch = kzalloc(sizeof(*vch), GFP_KERNEL);

... this renders any additional NUL-byte assignments (like the ones
strncpy() or strscpy_pad() does) redundant.

Subject: [PATCH 0748/1451] exportfs: add helpers to check if filesystem can
 encode/decode file handles

The logic of whether filesystem can encode/decode file handles is open
coded in many places.

In preparation to changing the logic, move the open coded logic into
inline helpers.

The VC4 mock helpers allocate the CRTC, encoders and connectors using a
call to kunit_kzalloc(), but the DRM device they are attache to survives
for longer than the test itself which leads to use-after-frees reported
by KASAN.

Switch to drmm_kzalloc to tie the lifetime of these objects to the main
DRM device.

Subject: [PATCH 0760/1451] iommu/dart: Remove the force_bypass variable

This flag just caches if the IO page size is larger than the CPU
PAGE_SIZE. This only needs to be checked in two places so remove the
confusingly named cache.

dart would like to not support paging domains at all if the IO page size
is larger than the CPU page size. In this case we should ideally fail
domain_alloc_paging(), as there is no point in creating a domain that can
never be attached. Move the test into apple_dart_finalize_domain().

The check in apple_dart_mod_streams() will prevent the domain from being
attached to the wrong dart

There is no HW limitation that prevents BLOCKED domains from working,
remove that test.

The check in apple_dart_of_xlate() is redundant since immediately after
the pgsize is checked. Remove it.

Remove the variable.

Subject: [PATCH 0765/1451] drm/syncobj: fix
 DRM_SYNCOBJ_WAIT_FLAGS_WAIT_AVAILABLE

If DRM_IOCTL_SYNCOBJ_TIMELINE_WAIT is invoked with the
DRM_SYNCOBJ_WAIT_FLAGS_WAIT_AVAILABLE flag set but no fence has yet been
submitted for the given timeline point the call will fail immediately
with EINVAL. This does not match the intended behavior where the call
should wait until the fence has been submitted (or the timeout expires).

The following small example program illustrates the issue. It should
wait for 5 seconds and then print ETIME, but instead it terminates right
away after printing EINVAL.

  #include <stdio.h>
  #include <fcntl.h>
  #include <time.h>
  #include <errno.h>
  #include <xf86drm.h>
  int main(void)
  {
      int fd = open("/dev/dri/card0", O_RDWR);
      uint32_t syncobj;
      drmSyncobjCreate(fd, 0, &syncobj);
      struct timespec ts;
      clock_gettime(CLOCK_MONOTONIC, &ts);
      uint64_t point = 1;
      if (drmSyncobjTimelineWait(fd, &syncobj, &point, 1,
                                 ts.tv_sec * 1000000000 + ts.tv_nsec + 5000000000, // 5s
                                 DRM_SYNCOBJ_WAIT_FLAGS_WAIT_AVAILABLE, NULL)) {
          printf("drmSyncobjTimelineWait failed %d\n", errno);
      }
  }

 ARCH_NPCM

The Nuvoton NPCM Video Capture/Differentiation Engine (VCD) and Encoding
Compression Engine (ECE) are only present on Nuvoton NPCM SoCs.  Hence
add a dependency on ARCH_NPCM, to prevent asking the user about these
drivers when configuring a kernel without  Nuvoton NPCM Architecture
support.

Subject: [PATCH 0767/1451] riscv: VMAP_STACK overflow detection thread-safe

commit 31da94c25aea ("riscv: add VMAP_STACK overflow detection") added
support for CONFIG_VMAP_STACK. If overflow is detected, CPU switches to
`shadow_stack` temporarily before switching finally to per-cpu
`overflow_stack`.

If two CPUs/harts are racing and end up in over flowing kernel stack, one
or both will end up corrupting each other state because `shadow_stack` is
not per-cpu. This patch optimizes per-cpu overflow stack switch by
directly picking per-cpu `overflow_stack` and gets rid of `shadow_stack`.

Following are the changes in this patch

 - Defines an asm macro to obtain per-cpu symbols in destination
   register.
 - In entry.S, when overflow is detected, per-cpu overflow stack is
   located using per-cpu asm macro. Computing per-cpu symbol requires
   a temporary register. x31 is saved away into CSR_SCRATCH
   (CSR_SCRATCH is anyways zero since we're in kernel).

Please see Links for additional relevant disccussion and alternative
solution.

Subject: [PATCH 0768/1451] riscv: Deduplicate IRQ stack switching

With CONFIG_IRQ_STACKS, we switch to a separate per-CPU IRQ stack
before calling handle_riscv_irq or __do_softirq. We currently
have duplicate inline assembly snippets for stack switching in
both code paths. Now that we can access per-CPU variables in
assembly, implement call_on_irq_stack in assembly, and use that
instead of redundant inline assembly.

Subject: [PATCH 0769/1451] riscv: Move global pointer loading to a macro

In Clang 17, -fsanitize=shadow-call-stack uses the newly declared
platform register gp for storing shadow call stack pointers. As
this is obviously incompatible with gp relaxation, in preparation
for CONFIG_SHADOW_CALL_STACK support, move global pointer loading
to a single macro, which we can cleanly disable when SCS is used
instead.

Subject: [PATCH 0770/1451] riscv: Implement Shadow Call Stack

Implement CONFIG_SHADOW_CALL_STACK for RISC-V. When enabled, the
compiler injects instructions to all non-leaf C functions to
store the return address to the shadow stack and unconditionally
load it again before returning, which makes it harder to corrupt
the return address through a stack overflow, for example.

The active shadow call stack pointer is stored in the gp
register, which makes SCS incompatible with gp relaxation. Use
--no-relax-gp to ensure gp relaxation is disabled and disable
global pointer loading.  Add SCS pointers to struct thread_info,
implement SCS initialization, and task switching

The Samsung touchscreen controllers are often used with external pull-up

a regulator to bring the lines into usable state. Otherwise, this might
cause spurious interrupts and reading from I2C will fail.

Document support for a "vddio-supply" that is enabled by the cyttsp5
driver so that the regulator gets enabled when needed.

Subject: [PATCH 0775/1451] exportfs: make ->encode_fh() a mandatory method for
 NFS export

Rename the default helper for encoding FILEID_INO32_GEN* file handles to
generic_encode_ino32_fh() and convert the filesystems that used the
default implementation to use the generic helper explicitly.

After this change, exportfs_encode_inode_fh() no longer has a default
implementation to encode FILEID_INO32_GEN* file handles.

This is a step towards allowing filesystems to encode non-decodeable
file handles for fanotify without having to implement any
export_operations.

Subject: [PATCH 0776/1451] exportfs: define FILEID_INO64_GEN* file handle
 types

Similar to the common FILEID_INO32* file handle types, define common
FILEID_INO64* file handle types.

The type values of FILEID_INO64_GEN and FILEID_INO64_GEN_PARENT are the
values returned by fuse and xfs for 64bit ino encoded file handle types.

Note that these type value are filesystem specific and they do not define
a universal file handle format, for example:
fuse encodes FILEID_INO64_GEN as [ino-hi32,ino-lo32,gen] and xfs encodes
FILEID_INO64_GEN as [hostr-order-ino64,gen] (a.k.a xfs_fid64).

The FILEID_INO64_GEN fhandle type is going to be used for file ids for
fanotify from filesystems that do not support NFS export.

Subject: [PATCH 0777/1451] exportfs: support encoding non-decodeable file
 handles by default

AT_HANDLE_FID was added as an API for name_to_handle_at() that request
the encoding of a file id, which is not intended to be decoded.

This file id is used by fanotify to describe objects in events.

So far, overlayfs is the only filesystem that supports encoding
non-decodeable file ids, by providing export_operations with an
->encode_fh() method and without a ->decode_fh() method.

Add support for encoding non-decodeable file ids to all the filesystems
that do not provide export_operations, by encoding a file id of type
FILEID_INO64_GEN from { i_ino, i_generation }.

A filesystem may that does not support NFS export, can opt-out of
encoding non-decodeable file ids for fanotify by defining an empty
export_operations struct (i.e. with a NULL ->encode_fh() method).

This allows the use of fanotify events with file ids on filesystems
like 9p which do not support NFS export to bring fanotify in feature
parity with inotify on those filesystems.

Note that fanotify also requires that the filesystems report a non-null
fsid.  Currently, many simple filesystems that have support for inotify
(e.g. debugfs, tracefs, sysfs) report a null fsid, so can still not be
used with fanotify in file id reporting mode.

Subject: [PATCH 0778/1451] fs: report f_fsid from s_dev for "simple"
 filesystems

There are many "simple" filesystems (*) that report null f_fsid in
statfs(2).  Those "simple" filesystems report sb->s_dev as the st_dev
field of the stat syscalls for all inodes of the filesystem (**).

In order to enable fanotify reporting of events with fsid on those
"simple" filesystems, report the sb->s_dev number in f_fsid field of
statfs(2).

(*) For most of the "simple" filesystem refered to in this commit, the
->statfs() operation is simple_statfs(). Some of those fs assign the
simple_statfs() method directly in their ->s_op struct and some assign it
indirectly via a call to simple_fill_super() or to pseudo_fs_fill_super()
with either custom or "simple" s_op.
We also make the same change to efivarfs and hugetlbfs, although they do
not use simple_statfs(), because they use the simple_* inode opreations
(e.g. simple_lookup()).

(**) For most of the "simple" filesystems, the ->getattr() method is not
assigned, so stat() is implemented by generic_fillattr().  A few "simple"
filesystem use the simple_getattr() method which also calls
generic_fillattr() to fill most of the stat struct.

The two exceptions are procfs and 9p. procfs implements several different
->getattr() methods, but they all end up calling generic_fillattr() to
fill the st_dev field from sb->s_dev.

9p has more complicated ->getattr() methods, but they too, end up calling
generic_fillattr() to fill the st_dev field from sb->s_dev.

Note that 9p and kernfs also call simple_statfs() from custom ->statfs()
methods which already fill the f_fsid field, but v9fs_statfs() calls
simple_statfs() only in case f_fsid was not filled and kenrfs_statfs()
overwrites f_fsid after calling simple_statfs().

Subject: [PATCH 0779/1451] freevxfs: derive f_fsid from bdev->bd_dev

The majority of blockdev filesystems, which do not have a UUID in their
on-disk format, derive f_fsid of statfs(2) from bdev->bd_dev.

Use the same practice for freevxfs.

This will allow reporting fanotify events with fanotify_event_info_fid.

Subject: [PATCH 0780/1451] fs: fix build error with CONFIG_EXPORTFS=m or not
 defined

Many of the filesystems that call the generic exportfs helpers do not
select the EXPORTFS config.

Move generic_encode_ino32_fh() to libfs.c, same as generic_fh_to_*()
to avoid having to fix all those config dependencies.

Subject: [PATCH 0785/1451] watchdog: it87_wdt: add IT8613 ID

This patch adds watchdog support for the ITE IT8613 watchdog.
IT8613 watchdog works in the same way as the other watchdogs supported
by it87_wdt.

Before this patch, IT8613 watchdog is not supported. After a modprobe,
dmesg reports:
  it87_wdt: Unknown Chip found, Chip 8613 Revision 000c
With this patch, modprobe it87_wdt recognizes the watchdog as the dmesg
output shows:
  it87_wdt: Chip IT8613 revision 12 initialized. timeout=60 sec (nowayout=0 testmode=0)

Watchdog tests on a LES v4 have been successful, the watchdog works as
expected with this patch [1].

Subject: [PATCH 0787/1451] sbsa_gwdt: Calculate timeout with 64-bit math

Commit abd3ac7902fb ("watchdog: sbsa: Support architecture version 1")
introduced new timer math for watchdog revision 1 with the 48 bit offset
register.

The gwdt->clk and timeout are u32, but the argument being calculated is
u64. Without a cast, the compiler performs u32 operations, truncating
intermediate steps, resulting in incorrect values.

A watchdog revision 1 implementation with a gwdt->clk of 1GHz and a
timeout of 600s writes 3647256576 to the one shot watchdog instead of
300000000000, resulting in the watchdog firing in 3.6s instead of 600s.

Force u64 math by casting the first argument (gwdt->clk) as a u64. Make
the order of operations explicit with parenthesis.

Subject: [PATCH 0789/1451] watchdog: wdat_wdt: Add timeout value as a param in
 ping method

According to the WDAT spec that states about WATCHDOG_ACTION_SET_COUNTDOWN_PERIOD:
"This action is required if WATCHDOG_ACTION_RESET does not explicitly write a new
countdown value to a register during a reset."
And that implies, WATCHDOG_ACTION_RESET may write a countdown value, thus may come
with a WATCHDOG_INSTRUCTION_WRITE_COUNTDOWN, thus need the timeout value as parameter
or would otherwise write 0.
The watchdog for SIONCT6126 need a entry WATCHDOG_INSTRUCTION_WRITE_COUNTDOWN for
WATCHDOG_ACTION_RESET action, I send this patch to support it.

Subject: [PATCH 0792/1451] watchdog: marvell_gti: Replace of_platform.h with
 explicit includes

The DT of_device.h and of_platform.h date back to the separate
of_platform_bus_type before it was merged into the regular platform bus.
As part of that merge prepping Arm DT support 13 years ago, they
"temporarily" include each other and pull in various other headers. In
preparation to fix this, adjust the includes for what is actually needed.

of_platform.h isn't needed, but of.h was implicitly included by it (via
of_device.h).

Subject: [PATCH 0799/1451] dt-bindings: watchdog: aspeed-wdt: Add
 aspeed,reset-mask property

This property configures the Aspeed watchdog timer's reset mask, which
controls which peripherals are reset when the watchdog timer expires.
Some platforms require that certain devices be left untouched across a
reboot; aspeed,reset-mask can now be used to express such constraints.

Subject: [PATCH 0803/1451] dt-bindings: display: ssd132x: Remove '-' before
 compatible enum

This is a leftover from when the binding schema had the compatible string
property enum as a 'oneOf' child and the '-' was not removed when 'oneOf'
got dropped during the binding review process.

Change it to an normal initializer and an added memcpy() that does not have

Subject: [PATCH 0806/1451] drm/i915: Flush WC GGTT only on required platforms
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

gen8_ggtt_invalidate() is only needed for limited set of platforms
where GGTT is mapped as WC. This was added as way to fix WC based GGTT in
commit 0f9b91c754b7 ("drm/i915: flush system agent TLBs on SNB") and
there are no reference in HW docs that forces us to use this on non-WC
backed GGTT.

This can also cause unwanted side-effects on XE_HP platforms where
GFX_FLSH_CNTL_GEN6 is not valid anymore.

v2: Add a func to detect wc ggtt detection (Ville)
v3: Improve commit log and add reference commit (Daniel)

Subject: [PATCH 0810/1451] ASoC: rockchip: Fix unused rockchip_i2s_tdm_match
 warning for !CONFIG_OF

Commit 9958d85968ed ("ASoC: Use device_get_match_data()") dropped the
unconditional use of rockchip_i2s_tdm_match resulting in this warning:

sound/soc/rockchip/rockchip_i2s_tdm.c:1315:34: warning: 'rockchip_i2s_tdm_match' defined but not used [-Wunused-const-variable=]

The fix is to drop of_match_ptr() which is not necessary because DT is
always used for this driver.

Overlayfs implements its own function to translate iocb flags into rw
flags, so that they can be passed into another vfs call.

With commit ce71bfea207b4 ("fs: align IOCB_* flags with RWF_* flags")
Jens created a 1:1 matching between the iocb flags and rw flags,
simplifying the conversion.

Subject: [PATCH 0814/1451] ovl: propagate IOCB_APPEND flag on writes to
 realfile

If ovl file is opened O_APPEND, the underlying realfile is also
opened O_APPEND, so it makes sense to propagate the IOCB_APPEND flags
on sync writes to realfile, just as we do with aio writes.

Effectively, because sync ovl writes are protected by inode lock,
this change only makes a difference if the realfile is written to (size
extending writes) from underneath overlayfs.  The behavior in this case
is undefined, so it is ok if we change the behavior (to fail the ovl
IOCB_APPEND write).

Subject: [PATCH 0815/1451] ovl: punt write aio completion to workqueue

We want to protect concurrent updates of ovl inode size and mtime
(i.e. ovl_copyattr()) from aio completion context.

Punt write aio completion to a workqueue so that we can protect
ovl_copyattr() with a spinlock.

Export sb_init_dio_done_wq(), so that overlayfs can use its own
dio workqueue to punt aio completions.

Subject: [PATCH 0819/1451] ovl: reorder ovl_want_write() after
 ovl_inode_lock()

Make the locking order of ovl_inode_lock() strictly between the two
vfs stacked layers, i.e.:
- ovl vfs locks: sb_writers, inode_lock, ...
- ovl_inode_lock
- upper vfs locks: sb_writers, inode_lock, ...

To that effect, move ovl_want_write() into the helpers ovl_nlink_start()
and ovl_copy_up_start which currently take the ovl_inode_lock() after
ovl_want_write().

Subject: [PATCH 0820/1451] ovl: do not open/llseek lower file with upper
 sb_writers held

overlayfs file open (ovl_maybe_lookup_lowerdata) and overlay file llseek
take the ovl_inode_lock, without holding upper sb_writers.

In case of nested lower overlay that uses same upper fs as this overlay,
lockdep will warn about (possibly false positive) circular lock
dependency when doing open/llseek of lower ovl file during copy up with
our upper sb_writers held, because the locking ordering seems reverse to
the locking order in ovl_copy_up_start():

- lower ovl_inode_lock
- upper sb_writers

Let the copy up "transaction" keeps an elevated mnt write count on upper
mnt, but leaves taking upper sb_writers to lower level helpers only when
they actually need it.  This allows to avoid holding upper sb_writers
during lower file open/llseek and prevents the lockdep warning.

Minimizing the scope of upper sb_writers during copy up is also needed
for fixing another possible deadlocks by a following patch.

Subject: [PATCH 0821/1451] ovl: do not encode lower fh with upper sb_writers
 held

When lower fs is a nested overlayfs, calling encode_fh() on a lower
directory dentry may trigger copy up and take sb_writers on the upper fs
of the lower nested overlayfs.

The lower nested overlayfs may have the same upper fs as this overlayfs,
so nested sb_writers lock is illegal.

Move all the callers that encode lower fh to before ovl_want_write().

Subject: [PATCH 0822/1451] ovl: Move xattr support to new xattrs.c file

This moves the code from super.c and inode.c, and makes ovl_xattr_get/set()
static.

This is in preparation for doing more work on xattrs support.

Subject: [PATCH 0824/1451] ovl: Support escaped overlay.* xattrs

There are cases where you want to use an overlayfs mount as a lowerdir
for another overlayfs mount. For example, if the system rootfs is on
overlayfs due to composefs, or to make it volatile (via tmps), then
you cannot currently store a lowerdir on the rootfs. This means you
can't e.g. store on the rootfs a prepared container image for use
using overlayfs.

To work around this, we introduce an escapment mechanism for overlayfs
xattrs. Whenever the lower/upper dir has a xattr named
"overlay.overlay.XYZ", we list it as "overlay.XYZ" in listxattrs, and
when the user calls getxattr or setxattr on "overlay.XYZ", we apply to
"overlay.overlay.XYZ" in the backing directories.

This allows storing any kind of overlay xattrs in a overlayfs mount
that can be used as a lowerdir in another mount. It is possible to
stack this mechanism multiple times, such that
"overlay.overlay.overlay.XYZ" will survive two levels of overlay mounts,
however this is not all that useful in practice because of stack depth
limitations of overlayfs mounts.

Note: These escaped xattrs are copied to upper during copy-up.

Subject: [PATCH 0825/1451] ovl: Add an alternative type of whiteout

An xattr whiteout (called "xwhiteout" in the code) is a reguar file of
zero size with the "overlay.whiteout" xattr set. A file like this in a
directory with the "overlay.whiteouts" xattrs set will be treated the
same way as a regular whiteout.

The "overlay.whiteouts" directory xattr is used in order to
efficiently handle overlay checks in readdir(), as we only need to
checks xattrs in affected directories.

The advantage of this kind of whiteout is that they can be escaped
using the standard overlay xattr escaping mechanism. So, a file with a
"overlay.overlay.whiteout" xattr would be unescaped to
"overlay.whiteout", which could then be consumed by another overlayfs
as a whiteout.

Overlayfs itself doesn't create whiteouts like this, but a userspace
mechanism could use this alternative mechanism to convert images that
may contain whiteouts to be used with overlayfs.

To work as a whiteout for both regular overlayfs mounts as well as
userxattr mounts both the "user.overlay.whiteout*" and the
"trusted.overlay.whiteout*" xattrs will need to be created.

 the copied layers will fail the verification of the lower root file handle.
 
+Nesting overlayfs mounts
+------------------------
+
+It is possible to use a lower directory that is stored on an overlayfs
+mount. For regular files this does not need any special care. However, files
+that have overlayfs attributes, such as whiteouts or "overlay.*" xattrs will be
+interpreted by the underlying overlayfs mount and stripped out. In order to
+allow the second overlayfs mount to see the attributes they must be escaped.
+
+Overlayfs specific xattrs are escaped by using a special prefix of
+"overlay.overlay.". So, a file with a "trusted.overlay.overlay.metacopy" xattr
+in the lower dir will be exposed as a regular file with a
+"trusted.overlay.metacopy" xattr in the overlayfs mount. This can be nested by
+repeating the prefix multiple time, as each instance only removes one prefix.
+
+A lower dir with a regular whiteout will always be handled by the overlayfs
+mount, so to support storing an effective whiteout file in an overlayfs mount an
+alternative form of whiteout is supported. This form is a regular, zero-size
+file with the "overlay.whiteout" xattr set, inside a directory with the
+"overlay.whiteouts" xattr set. Such whiteouts are never created by overlayfs,
+but can be used by userspace tools (like containers) that generate lower layers.
+These alternative whiteouts can be escaped using the standard xattr escape
+mechanism in order to properly nest to any depth.

Commit beae836e9c61 ("ovl: temporarily disable appending lowedirs")
removed the ability to append lowerdirs with syntax lowerdir=":<path>".
Remove leftover code and comments that are irrelevant with lowerdir
append mode disabled.

Subject: [PATCH 0828/1451] ovl: store and show the user provided lowerdir
 mount option

We are about to add new mount options for adding lowerdir one by one,
but those mount options will not support escaping.

For the existing case, where lowerdir mount option is provided as a colon
separated list, store the user provided (possibly escaped) string and
display it as is when showing the lowerdir mount option.

Subject: [PATCH 0830/1451] ovl: add support for appending lowerdirs one by one

Add new mount options lowerdir+ and datadir+ that can be used to add
layers to lower layers stack one by one.

Unlike the legacy lowerdir mount option, special characters (i.e. colons
and cammas) are not unescaped with these new mount options.

The new mount options can be repeated to compose a large stack of lower
layers, but they may not be mixed with the lagacy lowerdir mount option,
because for displaying lower layers in mountinfo, we do not want to mix
escaped with unescaped lower layers path syntax.

Similar to data-only layer rules with the lowerdir mount option, the
datadir+ option must follow at least one lowerdir+ option and the
lowerdir+ option must not follow the datadir+ option.

If the legacy lowerdir mount option follows lowerdir+ and datadir+
mount options, it overrides them.  Sepcifically, calling:

  fsconfig(FSCONFIG_SET_STRING, "lowerdir", "", 0);

can be used to reset previously setup lower layers.

Subject: [PATCH 0831/1451] closures: Better memory barriers

atomic_(dec|sub)_return_release() are a thing now - use them.

Also, delete the useless barrier in set_closure_fn(): it's redundant
with the memory barrier in closure_put(0.

Since closure_put() would now otherwise just have a release barrier, we
also need a new barrier when the ref hits 0 -
smp_acquire__after_ctrl_dep().

Subject: [PATCH 0832/1451] closures: Fix race in closure_sync()

As pointed out by Linus, closure_sync() was racy; we could skip blocking
immediately after a get() and a put(), but then that would skip any
barrier corresponding to the other thread's put() barrier.

To fix this, always do the full __closure_sync() sequence whenever any
get() has happened and the closure might have been used by other
threads.

From b0b5bbf99fc269e10d01c2a9873de5a042bdc7f5 Mon Sep 17 00:00:00 2001

Subject: [PATCH 0836/1451] bcachefs: Don't run bch2_delete_dead_snapshots()
 unnecessarily

Be a bit more careful about when bch2_delete_dead_snapshots needs to
run: it only needs to run synchronously if we're running fsck, and it
only needs to run at all if we have snapshot nodes to delete or if fsck
has noticed that it needs to run.

Also:
  Rename BCH_FS_HAVE_DELETED_SNAPSHOTS -> BCH_FS_NEED_DELETE_DEAD_SNAPSHOTS

  Kill bch2_delete_dead_snapshots_hook(), move functionality to
  bch2_mark_snapshot()

  Factor out bch2_check_snapshot_needs_deletion(), to explicitly check
  if we need to be running snapshot deletion.

Subject: [PATCH 0837/1451] bcachefs: bch2_btree_id_str()

Since we can run with unknown btree IDs, we can't directly index btree
IDs into fixed size arrays.

Subject: [PATCH 0838/1451] bcachefs: Fix btree_node_type enum

More forwards compatibility fixups: having BKEY_TYPE_btree at the end of
the enum conflicts with unnkown btree IDs, this shifts BKEY_TYPE_btree
to slot 0 and fixes things up accordingly.

Subject: [PATCH 0840/1451] bcachefs: Fix ca->oldest_gen allocation

The ca->oldest_gen array needs to be the same size as the bucket_gens
array; ca->mi.nbuckets is updated with only state_lock held, not
gc_lock, so bch2_gc_gens() could race with device resize and allocate
too small of an oldest_gens array.

Subject: [PATCH 0843/1451] bcachefs: Ensure devices are always correctly
 initialized

We can't mark device superblocks or allocate journal on a device that
isn't online.

That means we may need to do this on every mount, because we may have
formatted a new filesystem and then done the first mount
(bch2_fs_initialize()) in degraded mode.

Upcoming rebalance_work btree will require extent triggers to be
BTREE_TRIGGER_WANTS_OLD_AND_NEW - so to reduce potential confusion,
let's just make all triggers BTREE_TRIGGER_WANTS_OLD_AND_NEW.

From bf0d9e89de2e62fe9967ebb77b68d58d3812e4db Mon Sep 17 00:00:00 2001
From: Kent Overstreet <kent.overstreet@linux.dev>
Date: Sun, 22 Oct 2023 10:54:24 -0400
Subject: [PATCH 0846/1451] bcachefs: Split apart bch2_target_to_text(),
 bch2_target_to_text_sb()

Previously we just had bch2_opt_target_to_text() which could be passed
either a filesystem object or just a superblock - depending on if we
have a running filesystem or not.

Split these into two functions for clarity.

Subject: [PATCH 0848/1451] bcachefs: bch2_disk_path_to_text() no longer takes
 sb_lock

We're going to be using bch2_target_to_text() ->
bch2_disk_path_to_text() from bch2_bkey_ptrs_to_text() and
bch2_bkey_ptrs_invalid(), which can be called in any context.

This patch adds the actual label to bch_disk_group_cpu so that it can be
used by bch2_disk_path_to_text, and splits out bch2_disk_path_to_text()
into two variants - like the previous patch, one for when we have a
running filesystem and another for when we only have a superblock.

Subject: [PATCH 0849/1451] bcachefs: Ensure we don't exceed encoded_extent_max

The write path may (rarely) see an encoded (checksummed) extent that
exceeds encoded_extent_max - this can happen when we're moving an
existing extent that was not checksummed, but was given a checksum by
bch2_write_rechecksum().

Date: Sun, 22 Oct 2023 18:29:54 -0400
Subject: [PATCH 0853/1451] bcachefs: Guard against unknown compression options

Since compression options now include compression level, proper
validation is a bit more involved.

This adds bch2_compression_opt_valid(), and plumbs it around
appropriately.

From 633169035a7ccdfe3a9eba0202dc2135baa07c72 Mon Sep 17 00:00:00 2001
From: Kent Overstreet <kent.overstreet@linux.dev>
Date: Fri, 20 Oct 2023 13:32:42 -0400
Subject: [PATCH 0855/1451] bcachefs: moving_context now owns a btree_trans

btree_trans and moving_context are used together, and having the
moving_context owns the transaction object reduces some plumbing.

From 96a363a7e68832054f2a93249335fd3efd870aa3 Mon Sep 17 00:00:00 2001
From: Kent Overstreet <kent.overstreet@linux.dev>
Date: Mon, 23 Oct 2023 16:21:54 -0400
Subject: [PATCH 0857/1451] bcachefs: move: move_stats refactoring

data_progress_list is gone - it was redundant with moving_context_list

The upcoming rebalance rewrite is going to have it using two different
move_stats objects with the same moving_context, depending on whether
it's scanning or using the rebalance_work btree - this patch plumbs
stats around a bit differently so that will work.

 recover
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

gpu tlb flush is skipped if reset sem is held, it makes
mes_self_test fail since it involves add_hw_queue/remove_hw_queue
which needs tlb flush functional. Remove mes_self_test in gpu
recover sequence.

This patch is to fix the recover failure in gfx11.

Subject: [PATCH 0864/1451] drm/amdgpu: add unmap latency when gfx11 set kiq
 resources

[why]
If driver does not set unmap latency for KIQ, the default value of KIQ
unmap latency is zero. When do unmap queue, KIQ will return that almost
immediately after receiving unmap command. So, the queue status will be
saved to MQD incorrectly or lost in some chance.

[how]
Set unmap latency when do kiq set resources. The unmap latency is set to
be 1 second that is synchronized with Windows driver.

MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

If the size returned by drm buddy allocator is higher than
the required size, we take the higher size to calculate
the buffer start address. This is required if we couldn't
trim the buffer to the requested size. This will fix the
display corruption issue on APU's which has limited VRAM
size.

Subject: [PATCH 0869/1451] clocksource: timer-riscv: Don't enable/disable
 timer interrupt

Currently, we enable/disable timer interrupt at runtime to start/stop
timer events. This makes timer interrupt state go out-of-sync with
the Linux interrupt subsystem.

To address the above issue, we can stop a per-HART timer interrupt
by setting U64_MAX in timecmp CSR (or sbi_set_timer()) at the time
of handling timer interrupt.

Subject: [PATCH 0872/1451] riscv: correct pt_level name via
 pgtable_l5/4_enabled

The pt_level uses CONFIG_PGTABLE_LEVELS to display page table names.
But if page mode is downgraded from kernel cmdline or restricted by
the hardware in 64BIT, it will give a wrong name.

Like, using no4lvl for sv39, ptdump named the 1G-mapping as "PUD"
that should be "PGD":

0xffffffd840000000-0xffffffd900000000    0x00000000c0000000         3G PUD     D A G . . W R V

So select "P4D/PUD" or "PGD" via pgtable_l5/4_enabled to correct it.

Subject: [PATCH 0873/1451] RISC-V: clarify the QEMU workaround in ISA parser

Extensions prefixed with "Su" won't corrupt the workaround in many
cases.  The only exception is when the first multi-letter extension in the
ISA string begins with "Su" and is not prefixed with an underscore.

For instance, following ISA string can confuse this QEMU workaround.

*   "rv64imacsuclic" (RV64I + M + A + C + "Suclic")

However, this case is very unlikely because extensions prefixed by either
"Z", "Sm" or "Ss" will most likely precede first.

For instance, the "Suclic" extension (draft as of now) will be placed after
related "Smclic" and "Ssclic" extensions.  It's also highly likely that
other unprivileged extensions like "Zba" will precede.

It's also possible to suppress the issue in the QEMU workaround with an
underscore.  Following ISA string won't confuse the QEMU workaround.

*   "rv64imac_suclic" (RV64I + M + A + C + delimited "Suclic")

This fix is to tell kernel developers the nature of this workaround
precisely.  There are some "Su*" extensions to be ratified but don't worry
about this workaround too much.

This commit comes with other minor editorial fixes (for minor wording and
spacing issues, without changing the meaning).

It is looks like a merge issue. Samuel's

The value of vsense_select should be either 32
or 0 in both cases, so modify the
AW88399_DEV_VDSEL_VSENSE macro to 32.

 S-mode
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Misalignment trap handling is only supported for M-mode and uses direct
accesses to user memory. In S-mode, when handling usermode fault, this
requires to use the get_user()/put_user() accessors. Implement
load_u8(), store_u8() and get_insn() using these accessors for
userspace and direct text access for kernel.

Subject: [PATCH 0885/1451] riscv: add floating point insn support to
 misaligned access emulation
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

This support is partially based of openSBI misaligned emulation floating
point instruction support. It provides support for the existing
floating point instructions (both for 32/64 bits as well as compressed
ones). Since floating point registers are not part of the pt_regs
struct, we need to modify them directly using some assembly. We also
dirty the pt_regs status in case we modify them to be sure context
switch will save FP state. With this support, Linux is on par with
openSBI support.

This sysctl tuning option allows the user to disable misaligned access
handling globally on the system. This will also be used by misaligned
detection code to temporarily disable misaligned access handling.

Subject: [PATCH 0888/1451] riscv: report misaligned accesses emulation to
 hwprobe
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

hwprobe provides a way to report if misaligned access are emulated. In
order to correctly populate that feature, we can check if it actually
traps when doing a misaligned access. This can be checked using an
exception table entry which will actually be used when a misaligned
access is done from kernel mode.

Subject: [PATCH 0889/1451] riscv: add support for PR_SET_UNALIGN and
 PR_GET_UNALIGN
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Now that trap support is ready to handle misalignment errors in S-mode,
allow the user to control the behavior of misaligned accesses using
prctl(PR_SET_UNALIGN). Add an align_ctl flag in thread_struct which
will be used to determine if we should SIGBUS the process or not on
such fault.

Per a discussion last week, let's improve coordination between fs/iomap/
and the rest of the VFS by shifting Christian into the role of git tree
maintainer.  I'll stay on as reviewer and main developer, which will
free up some more time to clean up the code base a bit and help
filesystem maintainers port off of bufferheads and onto iomap.

Subject: [PATCH 0891/1451] NFSv4: fairly test all delegations on a SEQ4_
 revocation

When the client is required to use TEST_STATEID to discover which
delegation(s) have been revoked, it may continually test delegations at the
head of the list if the server continues to be unsatisfied and send
SEQ4_STATUS_RECALLABLE_STATE_REVOKED.  For a large number of delegations
this behavior is prone to live-lock because the client may never be able to
test and free revoked state at the end of the list since the
SEQ4_STATUS_RECALLABLE_STATE_REVOKED will cause us to flag delegations at
the head of the list to be tested.  This problem is further exacerbated by
the state manager's willingness to be scheduled out on a busy system while
testing the list of delegations.

Keep a generation counter for each attempt to test all delegations, and
skip delegations that have already been tested in the current pass.

Subject: [PATCH 0892/1451] nfs41: drop dependency between flexfiles layout
 driver and NFSv3 modules

The flexfiles layout driver depends on NFSv3 module as data servers
might be configure to provide nfsv3 only.

Disabling the nfsv3 protocol completely disables the flexfiles layout driver,
however, the data server still might support v4.1 protocol. Thus the strond
couling betwwen flexfiles and nfsv3 modules should be relaxed, as layout driver
will return UNSUPPORTED if not matching protocol is found.

Subject: [PATCH 0896/1451] SUNRPC: Fix RPC client cleaned up the freed pipefs
 dentries

RPC client pipefs dentries cleanup is in separated rpc_remove_pipedir()
workqueue,which takes care about pipefs superblock locking.
In some special scenarios, when kernel frees the pipefs sb of the
current client and immediately alloctes a new pipefs sb,
rpc_remove_pipedir function would misjudge the existence of pipefs
sb which is not the one it used to hold. As a result,
the rpc_remove_pipedir would clean the released freed pipefs dentries.

To fix this issue, rpc_remove_pipedir should check whether the
current pipefs sb is consistent with the original pipefs sb.

Subject: [PATCH 0898/1451] regmap: prevent noinc writes from clobbering cache

Currently, noinc writes are cached as if they were standard incrementing
writes, overwriting unrelated register values in the cache. Instead, we
want to cache the last value written to the register, as is done in the
accelerated noinc handler (regmap_noinc_readwrite).

Subject: [PATCH 0899/1451] rcu: Break rcu_node_0 --> &rq->__lock order

Commit 851a723e45d1 ("sched: Always clear user_cpus_ptr in
do_set_cpus_allowed()") added a kfree() call to free any user
provided affinity mask, if present. It was changed later to use
kfree_rcu() in commit 9a5418bc48ba ("sched/core: Use kfree_rcu()
in do_set_cpus_allowed()") to avoid a circular locking dependency
problem.

It turns out that even kfree_rcu() isn't safe for avoiding
circular locking problem. As reported by kernel test robot,
the following circular locking dependency now exists:

  &rdp->nocb_lock --> rcu_node_0 --> &rq->__lock

Solve this by breaking the rcu_node_0 --> &rq->__lock chain by moving
the resched_cpu() out from under rcu_node lock.

[peterz: heavily borrowed from Waiman's Changelog]
[paulmck: applied Z qiang feedback]

Subject: [PATCH 0900/1451] rcu: Introduce rcu_cpu_online()

Export the RCU point of view as to when a CPU is considered offline
(ie: when does RCU consider that a CPU is sufficiently down in the
hotplug process to not feature any possible read side).

This will be used by RCU-tasks whose vision of an offline CPU should
reasonably match the one of RCU core.

Subject: [PATCH 0901/1451] rcu/tasks: Handle new PF_IDLE semantics

The commit:

	cff9b2332ab7 ("kernel/sched: Modify initial boot task idle setup")

has changed the semantics of what is to be considered an idle task in
such a way that CPU boot code preceding the actual idle loop is excluded
from it.

This has however introduced new potential RCU-tasks stalls when either:

1) Grace period is started before init/0 had a chance to set PF_IDLE,
   keeping it stuck in the holdout list until idle ever schedules.

2) Grace period is started when some possible CPUs have never been
   online, keeping their idle tasks stuck in the holdout list until the
   CPU ever boots up.

3) Similar to 1) but with secondary CPUs: Grace period is started
   concurrently with secondary CPU booting, putting its idle task in
   the holdout list because PF_IDLE isn't yet observed on it. It stays
   then stuck in the holdout list until that CPU ever schedules. The
   effect is mitigated here by the hotplug AP thread that must run to
   bring the CPU up.

Fix this with handling the new semantics of PF_IDLE, keeping in mind
that it may or may not be set on an idle task. Take advantage of that to
strengthen the coverage of an RCU-tasks quiescent state within an idle
task, excluding the CPU boot code from it. Only the code running within
the idle loop is now a quiescent state, along with offline CPUs.

Subject: [PATCH 0902/1451] rcu/tasks-trace: Handle new PF_IDLE semantics

The commit:

	cff9b2332ab7 ("kernel/sched: Modify initial boot task idle setup")

has changed the semantics of what is to be considered an idle task in
such a way that the idle task of an offline CPU may not carry the
PF_IDLE flag anymore.

However RCU-tasks-trace tests the opposite assertion, still assuming
that idle tasks carry the PF_IDLE flag during their whole lifecycle.

Remove this assumption to avoid spurious warnings but keep the initial
test verifying that the idle task is the current task on any offline
CPU.

Subject: [PATCH 0903/1451] bcachefs: rebalance_work

This adds a new btree, rebalance_work, to eliminate scanning required
for finding extents that need work done on them in the background - i.e.
for the background_target and background_compression options.

rebalance_work is a bitset btree, where a KEY_TYPE_set corresponds to an
extent in the extents or reflink btree at the same pos.

A new extent field is added, bch_extent_rebalance, which indicates that
this extent has work that needs to be done in the background - and which
options to use. This allows per-inode options to be propagated to
indirect extents - at least in some circumstances. In this patch,
changing IO options on a file will not propagate the new options to
indirect extents pointed to by that file.

Updating (setting/clearing) the rebalance_work btree is done by the
extent trigger, which looks at the bch_extent_rebalance field.

Scanning is still requrired after changing IO path options - either just
for a given inode, or for the whole filesystem. We indicate that
scanning is required by adding a KEY_TYPE_cookie key to the
rebalance_work btree: the cookie counter is so that we can detect that
scanning is still required when an option has been flipped mid-way
through an existing scan.

Future possible work:
 - Propagate options to indirect extents when being changed
 - Add other IO path options - nr_replicas, ec, to rebalance_work so
   they can be applied in the background when they change
 - Add a counter, for bcachefs fs usage output, showing the pending
   amount of rebalance work: we'll probably want to do this after the
   disk space accounting rewrite (moving it to a new btree)

Subject: [PATCH 0904/1451] bcachefs: Fix kasan splat in members_v1_get()

This fixes an incorrect memcpy() in the recent members_v2 code - a
members_v1 member is BCH_MEMBER_V1_BYTES, not sizeof(struct bch_member).

Subject: [PATCH 0905/1451] bcachefs: Fix a kasan splat in bch2_dev_add()

This fixes a use after free - mi is dangling after the resize call.

Additionally, resizing the device's member info section was useless - we
were attempting to preallocate the space required before adding it to
the filesystem superblock, but there's other sections that we should
have been preallocating as well for that to work.

Subject: [PATCH 0907/1451] bcachefs: Add IO error counts to bch_member

We now track IO errors per device since filesystem creation.

IO error counts can be viewed in sysfs, or with the 'bcachefs
show-super' command.

From f5d26fa31ed2e260589f0bc8af010bb742f1231e Mon Sep 17 00:00:00 2001
From: Kent Overstreet <kent.overstreet@linux.dev>
Date: Wed, 25 Oct 2023 15:51:16 -0400
Subject: [PATCH 0908/1451] bcachefs: bch_sb_field_errors

Add a new superblock section to keep counts of errors seen since
filesystem creation: we'll be addingcounters for every distinct fsck
error.

The new superblock section has entries of the for [ id, count,
time_of_last_error ]; this is intended to let us see what errors are
occuring - and getting fixed - via show-super output.

Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev>

From b65db750e2bb9252321fd54c284edd73c1595a09 Mon Sep 17 00:00:00 2001
From: Kent Overstreet <kent.overstreet@linux.dev>
Date: Tue, 24 Oct 2023 20:44:36 -0400
Subject: [PATCH 0909/1451] bcachefs: Enumerate fsck errors

This patch adds a superblock error counter for every distinct fsck
error; this means that when analyzing filesystems out in the wild we'll
be able to see what sorts of inconsistencies are being found and repair,
and hence what bugs to look for.

Errors validating bkeys are not yet considered distinct fsck errors, but
this patch adds a new helper, bkey_fsck_err(), in order to add distinct
error types for them as well.

We should only be downgrading locks on success - otherwise, our
transaction restarts won't be getting the correct locks and we'll
livelock.

Subject: [PATCH 0921/1451] tools: ynl-gen: don't touch the output file if
 content is the same

I often regenerate all YNL files in the tree to make sure they
are in sync with the codegen and specs. Generator rewrites
the files unconditionally, so since make looks at file modification
time to decide what to rebuild - my next build takes longer.

We already generate the code to a tempfile most of the time,
only overwrite the target when we have to.

Subject: [PATCH 0923/1451] llc: verify mac len before reading mac header

LLC reads the mac header with eth_hdr without verifying that the skb
has an Ethernet header.

Syzbot was able to enter llc_rcv on a tun device. Tun can insert
packets without mac len and with user configurable skb->protocol
(passing a tun_pi header when not configuring IFF_NO_PI).

    tun_get_user+0x54c5/0x69c0 drivers/net/tun.c:2002

Add a mac_len test before all three eth_hdr(skb) calls under net/llc.

There are further uses in include/net/llc_pdu.h. All these are
protected by a test skb->protocol == ETH_P_802_2. Which does not
protect against this tun scenario.

But the mac_len test added in this patch in llc_fixup_skb will
indirectly protect those too. That is called from llc_rcv before any
other LLC code.

It is tempting to just add a blanket mac_len check in llc_rcv, but
not sure whether that could break valid LLC paths that do not assume
an Ethernet header. 802.2 LLC may be used on top of non-802.3
protocols in principle. The below referenced commit shows that used
to, on top of Token Ring.

At least one of the three eth_hdr uses goes back to before the start
of git history. But the one that syzbot exercises is introduced in
this commit. That commit is old enough (2008), that effectively all
stable kernels should receive this.

TIPC bearer-related names including link names must be null-terminated
strings. If a link name which is not null-terminated is passed through
netlink, strstr() and similar functions can cause buffer overrun. This
causes the above issue.

This patch changes the nla_policy for bearer-related names from NLA_STRING
to NLA_NUL_STRING. This resolves the issue by ensuring that only
null-terminated strings are accepted as bearer-related names.

syzbot reported similar uninit-value issue related to bearer names [2]. The
root cause of this issue is that a non-null-terminated bearer name was
passed. This patch also resolved this issue.

Fixes: 0655f6a8635b ("tipc: add bearer disable/enable to new netlink api")

Subject: [PATCH 0926/1451] net/tcp_sigpool: Fix some off by one bugs

The "cpool_populated" variable is the number of elements in the cpool[]
array that have been populated.  It is incremented in
tcp_sigpool_alloc_ahash() every time we populate a new element.
Unpopulated elements are NULL but if we have populated every element then
this code will read one element beyond the end of the array.

This patch simply surrounds with a #ifdef the new code requiring CGroups
support. It seems enough for the compiler and this is similar to
bpf_iter_css_{new,next,destroy}() functions where no other #ifdef have
been added in kernel/bpf/helpers.c and in the selftests.

Subject: [PATCH 0928/1451] rxrpc: Fix two connection reaping bugs

Fix two connection reaping bugs:

 (1) rxrpc_connection_expiry is in units of seconds, so
     rxrpc_disconnect_call() needs to multiply it by HZ when adding it to
     jiffies.

 (2) rxrpc_client_conn_reap_timeout() should set RXRPC_CLIENT_REAP_TIMER if
     local->kill_all_client_conns is clear, not if it is set (in which case
     we don't need the timer).  Without this, old client connections don't
     get cleaned up until the local endpoint is cleaned up.

Fixes: 5040011d073d ("rxrpc: Make the local endpoint hold a ref on a connected call")
Fixes: 0d6bf319bc5a ("rxrpc: Move the client conn cache management to the I/O thread")

Subject: [PATCH 0929/1451] bpf: Fix check_stack_write_fixed_off() to correctly
 spill imm

In check_stack_write_fixed_off(), imm value is cast to u32 before being
spilled to the stack. Therefore, the sign information is lost, and the
range information is incorrect when load from the stack again.

For the following prog:
0: r2 = r10
1: *(u64*)(r2 -40) = -44
2: r0 = *(u64*)(r2 - 40)
3: if r0 s<= 0xa goto +2
4: r0 = 1
5: exit
6: r0  = 0
7: exit

The verifier gives:
func#0 @0
0: R1=ctx(off=0,imm=0) R10=fp0
0: (bf) r2 = r10                      ; R2_w=fp0 R10=fp0
1: (7a) *(u64 *)(r2 -40) = -44        ; R2_w=fp0 fp-40_w=4294967252
2: (79) r0 = *(u64 *)(r2 -40)         ; R0_w=4294967252 R2_w=fp0
fp-40_w=4294967252
3: (c5) if r0 s< 0xa goto pc+2
mark_precise: frame0: last_idx 3 first_idx 0 subseq_idx -1
mark_precise: frame0: regs=r0 stack= before 2: (79) r0 = *(u64 *)(r2 -40)
3: R0_w=4294967252
4: (b7) r0 = 1                        ; R0_w=1
5: (95) exit
verification time 7971 usec
stack depth 40
processed 6 insns (limit 1000000) max_states_per_insn 0 total_states 0
peak_states 0 mark_read 0

So remove the incorrect cast, since imm field is declared as s32, and
__mark_reg_known() takes u64, so imm would be correctly sign extended
by compiler.

Subject: [PATCH 0931/1451] selftests/bpf: fix test_bpffs

Currently this tests tries to umount /sys/kernel/debug (TDIR) but the
system it is running on may have mounts below.

For example, danobi/vmtest [0] VMs have
    mount -t tracefs tracefs /sys/kernel/debug/tracing
as part of their init.

This change instead creates a "random" directory under /tmp and uses this
as TDIR.
If the directory already exists, ignore the error and keep moving on.

Test:

Originally:

    $ vmtest -k $KERNEL_REPO/arch/x86_64/boot/bzImage "./test_progs -vv -a test_bpffs"

Subject: [PATCH 0932/1451] bpf: Add __bpf_kfunc_{start,end}_defs macros

BPF kfuncs are meant to be called from BPF programs. Accordingly, most
kfuncs are not called from anywhere in the kernel, which the
-Wmissing-prototypes warning is unhappy about. We've peppered
__diag_ignore_all("-Wmissing-prototypes", ... everywhere kfuncs are
defined in the codebase to suppress this warning.

This patch adds two macros meant to bound one or many kfunc definitions.
All existing kfunc definitions which use these __diag calls to suppress
-Wmissing-prototypes are migrated to use the newly-introduced macros.
A new __diag_ignore_all - for "-Wmissing-declarations" - is added to the
__bpf_kfunc_start_defs macro based on feedback from Andrii on an earlier
version of this patch [0] and another recent mailing list thread [1].

In the future we might need to ignore different warnings or do other
kfunc-specific things. This change will make it easier to make such
modifications for all kfunc defs.

Subject: [PATCH 0933/1451] bpf: Add __bpf_hook_{start,end} macros

Not all uses of __diag_ignore_all(...) in BPF-related code in order to
suppress warnings are wrapping kfunc definitions. Some "hook point"
definitions - small functions meant to be used as attach points for
fentry and similar BPF progs - need to suppress -Wmissing-declarations.

We could use __bpf_kfunc_{start,end}_defs added in the previous patch in
such cases, but this might be confusing to someone unfamiliar with BPF
internals. Instead, this patch adds __bpf_hook_{start,end} macros,
currently having the same effect as __bpf_kfunc_{start,end}_defs, then
uses them to suppress warnings for two hook points in the kernel itself
and some bpf_testmod hook points as well.

Subject: [PATCH 0934/1451] cpufreq: qcom-nvmem: add support for IPQ8074

IPQ8074 comes in 3 families:
* IPQ8070A/IPQ8071A (Acorn) up to 1.4GHz
* IPQ8172/IPQ8173/IPQ8174 (Oak) up to 1.4GHz
* IPQ8072A/IPQ8074A/IPQ8076A/IPQ8078A (Hawkeye) up to 2.2GHz

So, in order to be able to share one OPP table lets add support for IPQ8074
family based of SMEM SoC ID-s as speedbin fuse is always 0 on IPQ8074.

IPQ8074 compatible is blacklisted from DT platdev as the cpufreq device
will get created by NVMEM CPUFreq driver.

Subject: [PATCH 0935/1451] cpufreq: qcom-nvmem: Enable cpufreq for ipq53xx

IPQ53xx have different OPPs available for the CPU based on
SoC variant. This can be determined through use of an eFuse
register present in the silicon.

Added support for ipq53xx on nvmem driver which helps to
determine OPPs at runtime based on the eFuse register which
has the CPU frequency limits. opp-supported-hw dt binding
can be used to indicate the available OPPs for each limit.

nvmem driver also creates the "cpufreq-dt" platform_device after
passing the version matching data to the OPP framework so that the
cpufreq-dt handles the actual cpufreq implementation.

Subject: [PATCH 0936/1451] cpufreq: qcom-nvmem: Introduce cpufreq for ipq95xx

IPQ95xx SoCs have different OPPs available for the CPU based on
the SoC variant. This can be determined from an eFuse register
present in the silicon.

Added support for ipq95xx on nvmem driver which helps to
determine OPPs at runtime based on the eFuse register which
has the CPU frequency limits. opp-supported-hw dt binding
can be used to indicate the available OPPs for each limit.

Subject: [PATCH 0937/1451] bpf: Check map->usercnt after timer->timer is
 assigned

When there are concurrent uref release and bpf timer init operations,
the following sequence diagram is possible. It will break the guarantee
provided by bpf_timer: bpf_timer will still be alive after userspace
application releases or unpins the map. It also will lead to kmemleak
for old kernel version which doesn't release bpf_timer when map is
released.

bpf program X:

bpf_timer_init()
  lock timer->lock
    read timer->timer as NULL
    read map->usercnt != 0

                process Y:

                close(map_fd)
                  // put last uref
                  bpf_map_put_uref()
                    atomic_dec_and_test(map->usercnt)
                      array_map_free_timers()
                        bpf_timer_cancel_and_free()
                          // just return
                          read timer->timer is NULL

    t = bpf_map_kmalloc_node()
    timer->timer = t
  unlock timer->lock

Fix the problem by checking map->usercnt after timer->timer is assigned,
so when there are concurrent uref release and bpf timer init, either
bpf_timer_cancel_and_free() from uref release reads a no-NULL timer
or the newly-added atomic64_read() returns a zero usercnt.

Because atomic_dec_and_test(map->usercnt) and READ_ONCE(timer->timer)
in bpf_timer_cancel_and_free() are not protected by a lock, so add
a memory barrier to guarantee the order between map->usercnt and
timer->timer. Also use WRITE_ONCE(timer->timer, x) to match the lockless
read of timer->timer in bpf_timer_cancel_and_free().

Subject: [PATCH 0939/1451] bpf: Relax allowlist for css_task iter

The newly added open-coded css_task iter would try to hold the global
css_set_lock in bpf_iter_css_task_new, so the bpf side has to be careful in
where it allows to use this iter. The mainly concern is dead locking on
css_set_lock. check_css_task_iter_allowlist() in verifier enforced css_task
can only be used in bpf_lsm hooks and sleepable bpf_iter.

This patch relax the allowlist for css_task iter. Any lsm and any iter
(even non-sleepable) and any sleepable are safe since they would not hold
the css_set_lock before entering BPF progs context.

This patch also fixes the misused BPF_TRACE_ITER in
check_css_task_iter_allowlist which compared bpf_prog_type with
bpf_attach_type.

Date: Thu, 2 Nov 2023 13:39:03 +0800
Subject: [PATCH 0942/1451] bpf: Fix precision tracking for BPF_ALU | BPF_TO_BE
 | BPF_END
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

BPF_END and BPF_NEG has a different specification for the source bit in
the opcode compared to other ALU/ALU64 instructions, and is either
reserved or use to specify the byte swap endianness. In both cases the
source bit does not encode source operand location, and src_reg is a
reserved field.

backtrack_insn() currently does not differentiate BPF_END and BPF_NEG
from other ALU/ALU64 instructions, which leads to r0 being incorrectly
marked as precise when processing BPF_ALU | BPF_TO_BE | BPF_END
instructions. This commit teaches backtrack_insn() to correctly mark
precision for such case.

While precise tracking of BPF_NEG and other BPF_END instructions are
correct and does not need fixing, this commit opt to process all BPF_NEG
and BPF_END instructions within the same if-clause to better align with
current convention used in the verifier (e.g. check_alu_op).

Subject: [PATCH 0943/1451] selftests/bpf: precision tracking test for BPF_NEG
 and BPF_END

As seen from previous commit that fix backtracking for BPF_ALU | BPF_TO_BE
| BPF_END, both BPF_NEG and BPF_END require special handling. Add tests
written with inline assembly to check that the verifier does not incorrecly
use the src_reg field of BPF_NEG and BPF_END (including bswap added in v4).

I am looking at syzbot reports triggering kernel stack overflows
involving a cascade of ipvlan devices.

We can save 8 bytes in struct flowi_common.

This patch alone will not fix the issue, but is a start.

Subject: [PATCH 0947/1451] net: dsa: lan9303: consequently nested-lock
 physical MDIO

When LAN9303 is MDIO-connected two callchains exist into
mdio->bus->write():

1. switch ports 1&2 ("physical" PHYs):

virtual (switch-internal) MDIO bus (lan9303_switch_ops->phy_{read|write})->
  lan9303_mdio_phy_{read|write} -> mdiobus_{read|write}_nested

2. LAN9303 virtual PHY:

virtual MDIO bus (lan9303_phy_{read|write}) ->
  lan9303_virt_phy_reg_{read|write} -> regmap -> lan9303_mdio_{read|write}

If the latter functions just take
mutex_lock(&sw_dev->device->bus->mdio_lock) it triggers a LOCKDEP
false-positive splat. It's false-positive because the first
mdio_lock in the second callchain above belongs to virtual MDIO bus, the
second mdio_lock belongs to physical MDIO bus.

Consequent annotation in lan9303_mdio_{read|write} as nested lock
(similar to lan9303_mdio_phy_{read|write}, it's the same physical MDIO bus)
prevents the following splat:

Since commit 833bac7ec392 ("net/smc: Fix setsockopt and sysctl to

default values for the smc.rmem and smc.wmem sysctl variables
which are no longer derived from the TCP IPv4 buffer sizes.

Fixup the kernel documentation to reflect this change, too.

Subject: [PATCH 0951/1451] dccp: Call security_inet_conn_request() after
 setting IPv4 addresses.

Initially, commit 4237c75c0a35 ("[MLSXFRM]: Auto-labeling of child
sockets") introduced security_inet_conn_request() in some functions
where reqsk is allocated.  The hook is added just after the allocation,
so reqsk's IPv4 remote address was not initialised then.

However, SELinux/Smack started to read it in netlbl_req_setattr()
after the cited commits.

This bug was partially fixed by commit 284904aa7946 ("lsm: Relocate
the IPv4 security_inet_conn_request() hooks").

This patch fixes the last bug in DCCPv4.

after commit e1adea927080 ("calipso: Allow request sockets to be
relabelled by the lsm.").

Commit 284904aa7946 ("lsm: Relocate the IPv4 security_inet_conn_request()
hooks") fixed that kind of issue only in TCPv4 because IPv6 labeling was
not supported at that time.  Finally, the same issue was introduced again
in IPv6.

Let's apply the same fix on DCCPv6 and TCPv6.

Fixes: e1adea927080 ("calipso: Allow request sockets to be relabelled by the lsm.")

Subject: [PATCH 0953/1451] net: r8169: Disable multicast filter for RTL8168H
 and RTL8107E

RTL8168H and RTL8107E ethernet adapters erroneously filter unicast
eapol packets unless allmulti is enabled. These devices correspond to
RTL_GIGA_MAC_VER_46 and VER_48. Add an exception for VER_46 and VER_48
in the same way that VER_35 has an exception.

There are architectures where char is not signed. If so, the following

Subject: [PATCH 0960/1451] riscv: configs: defconfig: Enable configs required
 for RZ/Five SoC

Enable the configs required by the below IP blocks which are
present on RZ/Five SoC:
* ADC
* CANFD
* DMAC
* eMMC/SDHI
* OSTM
* RAVB (+ Micrel PHY)
* RIIC
* RSPI
* SSI (Sound+WM8978 codec)
* Thermal
* USB (PHY/RESET/OTG)

Along with the above some core configs are enabled too,
-> CPU frequency scaling as RZ/Five does support this.
-> MTD is enabled as RSPI can be connected to flash chips
-> Enabled I2C chardev so that it enables userspace to read/write
   i2c devices (similar to arm64)
-> Thermal configs as RZ/Five SoC does have thermal unit
-> GPIO regulator as we might have IP blocks for which voltage
   levels are controlled by GPIOs
-> OTG configs as RZ/Five USB can support host/function
-> Gadget configs so that we can test USB function (as done in arm64

Subject: [PATCH 0961/1451] RISC-V: hwprobe: Fix vDSO SIGSEGV

A hwprobe pair key is signed, but the hwprobe vDSO function was
only checking that the upper bound was valid. In order to help
avoid this type of problem in the future, and in anticipation of
this check becoming more complicated with sparse keys, introduce
and use a "key is valid" predicate function for the check.

Subject: [PATCH 0962/1451] swiotlb: do not free decrypted pages if dynamic

Fix these two error paths:

1. When set_memory_decrypted() fails, pages may be left fully or partially
   decrypted.

2. Decrypted pages may be freed if swiotlb_alloc_tlb() determines that the
   physical address is too high.

To fix the first issue, call set_memory_encrypted() on the allocated region
after a failed decryption attempt. If that also fails, leak the pages.

To fix the second issue, check that the TLB physical address is below the
requested limit before decrypting.

Let the caller differentiate between unsuitable physical address (=> retry
from a lower zone) and allocation failures (=> no point in retrying).

Subject: [PATCH 0963/1451] Fix termination state for idr_for_each_entry_ul()

The comment for idr_for_each_entry_ul() states

  after normal termination @entry is left with the value NULL

This is not correct in the case where UINT_MAX has an entry in the idr.
In that case @entry will be non-NULL after termination.
No current code depends on the documentation being correct, but to
save future code we should fix it.

Also fix idr_for_each_entry_continue_ul().  While this is not documented
as leaving @entry as NULL, the mellanox driver appears to depend on
it doing so.  So make that explicit in the documentation as well as in
the code.

In the PMTU test, when all previous tests are skipped and the new test

treats this as an assignment, causing the check to pass every time.

Consequently, regardless of how many tests have failed, if the latest test
passes, the PMTU test will report a pass.

Subject: [PATCH 0966/1451] tcp: fix fastopen code vs usec TS

After blamed commit, TFO client-ack-dropped-then-recovery-ms-timestamps
packetdrill test failed.

David Morley and Neal Cardwell started investigating and Neal pointed
that we had :

tcp_conn_request()
  tcp_try_fastopen()
   -> tcp_fastopen_create_child
     -> child = inet_csk(sk)->icsk_af_ops->syn_recv_sock()
       -> tcp_create_openreq_child()
          -> copy req_usec_ts from req:
          newtp->tcp_usec_ts = treq->req_usec_ts;
          // now the new TFO server socket always does usec TS, no matter
          // what the route options are...
  send_synack()
    -> tcp_make_synack()
        // disable tcp_rsk(req)->req_usec_ts if route option is not present:
        if (tcp_rsk(req)->req_usec_ts < 0)
                tcp_rsk(req)->req_usec_ts = dst_tcp_usec_ts(dst);

tcp_conn_request() has the initial dst, we can initialize
tcp_rsk(req)->req_usec_ts there instead of later in send_synack();

This means tcp_rsk(req)->req_usec_ts can be a boolean.

Many thanks to David an Neal for their help.

 value parsing

ti,otap-del-sel-legacy/ti,itap-del-sel-legacy passed from DT
are currently ignored for all SD/MMC and eMMC modes. Fix this
by making start loop index to MMC_TIMING_LEGACY.

Subject: [PATCH 0971/1451] Revert "mmc: core: Capture correct oemid-bits for
 eMMC cards"

This reverts commit 84ee19bffc9306128cd0f1c650e89767079efeff.

The commit above made quirks with an OEMID fail to be applied, as they
were checking card->cid.oemid for the full 16 bits defined in MMC_FIXUP
macros but the field would only contain the bottom 8 bits.

eMMC v5.1A might have bogus values in OEMID's higher bits so another fix
will be made, but it has been decided to revert this until that is ready.

 - While fixing this bug, add PSH flag handling and represent
   flags the way tcpdump does : [S], [S.], [P.]
 - Print 4-tuples more consistently between families.

Subject: [PATCH 0976/1451] exfat: fix setting uninitialized time to
 ctime/atime

An uninitialized time is set to ctime/atime in __exfat_write_inode().
It causes xfstests generic/003 and generic/192 to fail.

And since there will be a time gap between setting ctime/atime to
the inode and writing back the inode, so ctime/atime should not be
set again when writing back the inode.

Subject: [PATCH 0977/1451] exfat: fix ctime is not updated

Commit 4c72a36edd54 ("exfat: convert to new timestamp accessors")
removed attr_copy() from exfat_set_attr().
It causes xfstests generic/221 to fail. In xfstests generic/221,
it tests ctime should be updated even if futimens() update atime
only. But in this case, ctime will not be updated if attr_copy()
is removed.

attr_copy() may also update other attributes, and removing it may
cause other bugs, so this commit restores to call attr_copy() in
exfat_set_attr().

Subject: [PATCH 0978/1451] io_uring/rw: don't attempt to allocate async data
 if opcode doesn't need it

The new read multishot method doesn't need to allocate async data ever,
as it doesn't do vectored IO and it must only be used with provided
buffers. While it doesn't have ->prep_async() set, it also sets
->async_size to 0, which is different from any other read/write type we
otherwise support.

If it's used on a file type that isn't pollable, we do try and allocate
this async data, and then try and use that data. But since we passed in
a size of 0 for the data, we get a NULL back on data allocation. We then
proceed to dereference that to copy state, and that obviously won't end
well.

Add a check in io_setup_async_rw() for this condition, and avoid copying
state. Also add a check for whether or not buffer selection is specified
in prep while at it.

Subject: [PATCH 0983/1451] drm/amdgpu: don't use ATRM for external devices

The ATRM ACPI method is for fetching the dGPU vbios rom
image on laptops and all-in-one systems.  It should not be
used for external add in cards.  If the dGPU is thunderbolt
connected, don't try ATRM.

v2: pci_is_thunderbolt_attached only works for Intel.  Use
    pdev->external_facing instead.
v3: dev_is_removable() seems to be what we want

Subject: [PATCH 0984/1451] drm/amdgpu: don't use pci_is_thunderbolt_attached()

It's only valid on Intel systems with the Intel VSEC.
Use dev_is_removable() instead.  This should do the right
thing regardless of the platform.

Subject: [PATCH 0987/1451] drm/amdgpu: ungate power gating when system suspend

[Why] During suspend, if GFX DPM is enabled and GFXOFF feature is
enabled the system may get hung. So, it is suggested to disable
GFXOFF feature during suspend and enable it after resume.

[How] Update the code to disable GFXOFF feature during suspend and enable
it after resume.

Subject: [PATCH 0988/1451] drm/amdgpu: add a retry for IP discovery init

AMD dGPUs have integrated FW that runs as soon as the
device gets power and initializes the board (determines
the amount of memory, provides configuration details to
the driver, etc.).  For direct PCIe attached cards this
happens as soon as power is applied and normally completes
well before the OS has even started loading.  However, with
hotpluggable ports like USB4, the driver needs to wait for
this to complete before initializing the device.

This normally takes 60-100ms, but could take longer on
some older boards periodically due to memory training.

Retry for up to a second.  In the non-hotplug case, there
should be no change in behavior and this should complete
on the first try.

v2: adjust test criteria
v3: adjust checks for the masks, only enable on removable devices
v4: skip bif_fb_en check

Subject: [PATCH 0990/1451] drm/amdgpu: don't put MQDs in VRAM on ARM | ARM64
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Issues were reported with commit 1cfb4d612127
("drm/amdgpu: put MQDs in VRAM") on an ADLINK Ampere
Altra Developer Platform (AVA developer platform).

Various ARM systems seem to have problems related
to PCIe and MMIO access.  In this case, I'm not sure
if this is specific to the ADLINK platform or ARM
in general.  Seems to be some coherency issue with
VRAM.  For now, just don't put MQDs in VRAM on ARM.

Subject: [PATCH 0991/1451] drm/amdkfd: Populate cache info for GFX 9.4.3

GFX 9.4.3 uses a new version of the GC info table which
contains the cache info. This patch adds a new function
to populate the cache info from IP discovery for GFX 9.4.3.

Subject: [PATCH 0994/1451] drm/amd/display: Increase frame warning limit with
 KASAN or KCSAN in dml2

When building ARCH=x86_64 allmodconfig with clang, which will typically
have sanitizers enabled, there is a warning about a large stack frame.

  drivers/gpu/drm/amd/amdgpu/../display/dc/dml2/display_mode_core.c:6265:13: error: stack frame size (2520) exceeds limit (2048) in 'dml_prefetch_check' [-Werror,-Wframe-larger-than]
   6265 | static void dml_prefetch_check(struct display_mode_lib_st *mode_lib)
        |             ^
  1 error generated.

Notably, GCC 13.2.0 does not do too much of a better job, as it is right
at the current limit of 2048 (and others have reported being over with
older GCC versions):

  drivers/gpu/drm/amd/amdgpu/../display/dc/dml2/display_mode_core.c: In function 'dml_prefetch_check':
  drivers/gpu/drm/amd/amdgpu/../display/dc/dml2/display_mode_core.c:6705:1: error: the frame size of 2048 bytes is larger than 1800 bytes [-Werror=frame-larger-than=]
   6705 | }
        | ^

In the past, these warnings have been avoided by reducing the number of
parameters to various functions so that not as many arguments need to be
passed on the stack. However, these patches take a good amount of effort
to write despite being mechanical due to code structure and complexity
and they are never carried forward to new generations of the code so
that effort has to be expended every new hardware generation, which
becomes harder to justify as time goes on.

To avoid having a noticeable or lengthy breakage in all{mod,yes}config,
which are easy testing targets that have -Werror enabled, increase the
limit for configurations that have KASAN or KCSAN enabled by 50% so that
cases of extremely poor code generation can still be caught while not
breaking the majority of builds. CONFIG_KMSAN also causes high stack
usage but the frame limit is already set to zero when it is enabled,
which is accounted for by the check for CONFIG_FRAME_WARN=0 in the dml2
Makefile.

 mes_self_test

Use a proper MEID to make sure the CP_HQD_* and CP_GFX_HQD_* registers
can be touched when initialize the compute and gfx mqd in mes_self_test.
Otherwise, we expect no response from CP and an GRBM eventual timeout.

Subject: [PATCH 1002/1451] drm/amd/swsmu: update smu v14_0_0 driver if and
 metrics table

Update driver if headers and metrics table in smu v14_0_0 after smu fw promotion.
Drop the legacy metrics table and add warning of checking pmfw version.

Subject: [PATCH 1006/1451] drm/amd/display: Program plane color setting
 correctly

[why]
There are some registers for plane
color that are skipped programming
on resume. Need to add those as part
of the sequence.

[how]
Add new function hook for programming
plane color control.

Subject: [PATCH 1007/1451] drm/amd/display: Fix blend LUT programming

[Why]
LUT write index does not get reset to zero when writing the LUT values
for each separate RGB component, which results in wrong data for 2 of
the 3 components.

[How]
Reset LUT write index to zero before writing each component's data.

Subject: [PATCH 1009/1451] io_uring/net: ensure socket is marked connected on
 connect retry

io_uring does non-blocking connection attempts, which can yield some
unexpected results if a connect request is re-attempted by an an
application. This is equivalent to the following sync syscall sequence:

sock = socket(AF_INET, SOCK_STREAM | SOCK_NONBLOCK, IPPROTO_TCP);
connect(sock, &addr, sizeof(addr);

ret == -1 and errno == EINPROGRESS expected here. Now poll for POLLOUT
on sock, and when that returns, we expect the socket to be connected.
But if we follow that procedure with:

connect(sock, &addr, sizeof(addr));

you'd expect ret == -1 and errno == EISCONN here, but you actually get
ret == 0. If we attempt the connection one more time, then we get EISCON
as expected.

io_uring used to do this, but turns out that bluetooth fails with EBADFD
if you attempt to re-connect. Also looks like EISCONN _could_ occur with
this sequence.

Retain the ->in_progress logic, but work-around a potential EISCONN or
EBADFD error and only in those cases look at the sock_error(). This
should work in general and avoid the odd sequence of a repeated connect
request returning success when the socket is already connected.

This is all a side effect of the socket state being in a CONNECTING
state when we get EINPROGRESS, and only a re-connect or other related
operation will turn that into CONNECTED.

From 5995d90d2d19f337df6a50bcf4699ef053214dac Mon Sep 17 00:00:00 2001
From: Xiubo Li <xiubli@redhat.com>
Date: Mon, 12 Jun 2023 10:50:38 +0800
Subject: [PATCH 1012/1451] ceph: rename _to_client() to _to_fs_client()

We need to covert the inode to ceph_client in the following commit,
and will add one new helper for that, here we rename the old helper
to _fs_client().

From 38d46409c4639a1d659ebfa70e27a8bed6b8ee1d Mon Sep 17 00:00:00 2001
From: Xiubo Li <xiubli@redhat.com>
Date: Mon, 12 Jun 2023 09:04:07 +0800
Subject: [PATCH 1013/1451] ceph: print cluster fsid and client global_id in
 all debug logs

Multiple CephFS mounts on a host is increasingly common so
disambiguating messages like this is necessary and will make it easier
to debug issues.

At the same this will improve the debug logs to make them easier to
troubleshooting issues, such as print the ino# instead only printing
the memory addresses of the corresponding inodes and print the dentry
names instead of the corresponding memory addresses for the dentry,etc.

Subject: [PATCH 1016/1451] ceph: stash idmapping in mdsc request

When sending a mds request cephfs will send relevant data for the
requested operation. For creation requests the caller's fs{g,u}id is
used to set the ownership of the newly created filesystem object. For
setattr requests the caller can pass in arbitrary {g,u}id values to
which the relevant filesystem object is supposed to be changed.

If the caller is performing the relevant operation via an idmapped mount
cephfs simply needs to take the idmapping into account when it sends the
relevant mds request.

In order to support idmapped mounts for cephfs we stash the idmapping
whenever they are relevant for the operation for the duration of the
request. Since mds requests can be queued and performed asynchronously
we make sure to keep the idmapping around and release it once the
request has finished.

In follow-up patches we will use this to send correct ownership
information over the wire. This patch just adds the basic infrastructure
to keep the idmapping around. The actual conversion patches are all
fairly minimal.

Subject: [PATCH 1017/1451] ceph: handle idmapped mounts in
 create_request_message()

Inode operations that create a new filesystem object such as ->mknod,
->create, ->mkdir() and others don't take a {g,u}id argument explicitly.
Instead the caller's fs{g,u}id is used for the {g,u}id of the new
filesystem object.

In order to ensure that the correct {g,u}id is used map the caller's
fs{g,u}id for creation requests. This doesn't require complex changes.
It suffices to pass in the relevant idmapping recorded in the request
message. If this request message was triggered from an inode operation
that creates filesystem objects it will have passed down the relevant
idmaping. If this is a request message that was triggered from an inode
operation that doens't need to take idmappings into account the initial
idmapping is passed down which is an identity mapping.

This change uses a new cephfs protocol extension CEPHFS_FEATURE_HAS_OWNER_UIDGID
which adds two new fields (owner_{u,g}id) to the request head structure.
So, we need to ensure that MDS supports it otherwise we need to fail
any IO that comes through an idmapped mount because we can't process it
in a proper way. MDS server without such an extension will use caller_{u,g}id
fields to set a new inode owner UID/GID which is incorrect because caller_{u,g}id
values are unmapped. At the same time we can't map these fields with an
idmapping as it can break UID/GID-based permission checks logic on the
MDS side. This problem was described with a lot of details at [1], [2].

Subject: [PATCH 1018/1451] ceph: add enable_unsafe_idmap module parameter
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

This parameter is used to decide if we allow
to perform IO on idmapped mount in case when MDS lacks
support of CEPHFS_FEATURE_HAS_OWNER_UIDGID feature.

In this case we can't properly handle MDS permission
checks and if UID/GID-based restrictions are enabled
on the MDS side then IO requests which go through an
idmapped mount may fail with -EACCESS/-EPERM.
Fortunately, for most of users it's not a case and
everything should work fine. But we put work "unsafe"
in the module parameter name to warn users about
possible problems with this feature and encourage
update of cephfs MDS.

Subject: [PATCH 1029/1451] pinctrl: provide new GPIO-to-pinctrl glue helpers

Currently the pinctrl GPIO helpers all take a number from the global
GPIO numberspace - of which we're trying to get rid of as argument.

These helpers are almost universally called from GPIOLIB driver
callbacks which take a pointer to the backing gpio_chip and the
controller-relative offset as arguments.

Let's provide improved variants of these functions that match the
GPIOLIB signatures as the first step in removing the older flavor.

Subject: [PATCH 1052/1451] pinctrl: mediatek: common: use new pinctrl GPIO
 helpers

Replace the pinctrl helpers taking the global GPIO number as argument
with the improved variants that instead take a pointer to the GPIO chip
and the controller-relative offset.

From acb38be654f9af05fe626b37ea83e119cd310c3c Mon Sep 17 00:00:00 2001
From: Bartosz Golaszewski <bartosz.golaszewski@linaro.org>
Date: Tue, 3 Oct 2023 11:56:03 +0200
Subject: [PATCH 1070/1451] treewide: rename pinctrl_gpio_request_new()

Now that pinctrl_gpio_request() is no longer used, let's drop the '_new'
suffix from its improved variant.

From 315c46f9b696be82972290d50349c7824276b844 Mon Sep 17 00:00:00 2001
From: Bartosz Golaszewski <bartosz.golaszewski@linaro.org>
Date: Tue, 3 Oct 2023 11:58:30 +0200
Subject: [PATCH 1072/1451] treewide: rename pinctrl_gpio_direction_input_new()

Now that pinctrl_gpio_direction_input() is no longer used, let's drop the
'_new' suffix from its improved variant.

Signed-off-by: Bartosz Golaszewski <bartosz.golaszewski@linaro.org>
Acked-by: Linus Walleij <linus.walleij@linaro.org>

From b679d6c06b2b29187374f9f4da7eea1961c2eeaa Mon Sep 17 00:00:00 2001
From: Bartosz Golaszewski <bartosz.golaszewski@linaro.org>
Date: Tue, 3 Oct 2023 11:59:51 +0200
Subject: [PATCH 1073/1451] treewide: rename
 pinctrl_gpio_direction_output_new()

Now that pinctrl_gpio_direction_output() is no longer used, let's drop
the '_new' suffix from its improved variant.

Subject: [PATCH 1074/1451] treewide: rename pinctrl_gpio_set_config_new()

Now that pinctrl_gpio_set_config() is no longer used, let's drop the
'_new' suffix from its improved variant.

Subject: [PATCH 1079/1451] pinctrl: change the signature of
 pinctrl_ready_for_gpio_range()

Modify pinctrl_ready_for_gpio_range() to be in line with public GPIO
helpers and take a pair of GPIO chip & offset as arguments

Subject: [PATCH 1089/1451] pinctrl: ocelot: drop the wrapper around
 pinctrl_gpio_direction_input()

pinctrl_gpio_direction_input() now has the same signature as the
wrapper around it so we can drop them.

Subject: [PATCH 1099/1451] bcachefs: Fix build errors with gcc 10

gcc 10 seems to complain about array bounds in situations where gcc 11
does not - curious.

This unfortunately requires adding some casts for now; we may
investigate getting rid of our __u64 _data[] VLA in a future patch so
that our start[0] members can be VLAs.

Subject: [PATCH 1100/1451] bcachefs: Ensure srcu lock is not held too long

The SRCU read lock that btree_trans takes exists to make it safe for
bch2_trans_relock() to deref pointers to btree nodes/key cache items we
don't have locked, but as a side effect it blocks reclaim from freeing
those items.

Thus, it's important to not hold it for too long: we need to
differentiate between bch2_trans_unlock() calls that will be only for a
short duration, and ones that will be for an unbounded duration.

This introduces bch2_trans_unlock_long(), to be used mainly by the data
move paths.

Subject: [PATCH 1102/1451] bcachefs: serialize on cached key in early bucket
 allocator

bcachefs had a transient bug where freespace_initialized was not
properly being set, which lead to unexpected use of the early bucket
allocator at runtime. This issue has been fixed, but the existence
of it uncovered a coherency issue in the early bucket allocation
code that is somewhat related to how uncached iterators deal with
the key cache.

The problem itself manifests as occasional failure of generic/113
due to corruption, often seen as a duplicate backpointer or multiple
data types per-bucket error. The immediate cause of the error is a
racing bucket allocation along the lines of the following sequence:

- Task 1 selects key A in bch2_bucket_alloc_early() and schedules.
- Task 2 selects the same key A, but proceeds to complete the
  allocation and associated I/O, after which it releases the
  open_bucket.
- Task 1 resumes with key A, but does not recognize the bucket is
  now allocated because the open_bucket has been removed
  from the hash when it was released in the previous step.

This generally shouldn't happen because the allocating task updates
the alloc btree key before releasing the bucket. This is not
sufficient in this particular instance, however, because an uncached
iterator for a cached btree doesn't actually lock the key cache slot
when no key exists for a given slot in the cache. Thus the fact that
the allocation side updates the cached key means that multiple
uncached iters can stumble across the same alloc key and duplicate
the bucket allocation as described above.

This is something that probably needs a longer term fix in the
iterator code. As a short term fix, close the race through explicit
use of a cached iterator for likely allocation candidates. We don't
want to scan the btree with a cached iterator because that would
unnecessarily pollute the cache. This mitigates cache pollution by
primarily scanning the tree with an uncached iterator, but closes
the race by creating a key cache entry for any prospective slot
prior to the bucket allocation attempt (also similar to how
_alloc_freelist() works via try_alloc_bucket()). This survives many
iterations of generic/113 on a kernel hacked to always use the early
bucket allocator.

Subject: [PATCH 1103/1451] bcachefs: update alloc cursor in early bucket
 allocator

A recent bug report uncovered a scenario where a filesystem never
runs with freespace_initialized, and therefore the user observes
significantly degraded write performance by virtue of running the
early bucket allocator. The associated bug aside, the primary cause
of the performance drop in this particular instance is that the
early bucket allocator does not update the allocation cursor. This
means that every allocation walks the alloc btree from the first
bucket of the associated device looking for a bucket marked as free
space.

Update the early allocator code to set the alloc cursor to the last
processed position in the tree, similar to how the freelist
allocator behaves. With the alloc_cursor being updated, the retry
logic also needs to be updated to restart from the beginning of the
device when a free bucket is not available between the cursor and
the end of the device. Track the restart position in a first_bucket
variable to make the code a bit more easily readable and consistent
with the freelist allocator.

Subject: [PATCH 1104/1451] bcachefs: fix odebug warn and lockdep splat due to
 on-stack rhashtable

Guenter Roeck reports a lockdep splat and DEBUG_OBJECTS_WORK related
warning when bch2_copygc_thread() initializes its rhashtable. The
lockdep splat relates to a warning print caused by the fact that the
rhashtable exists on the stack but is not annotated as so. This is
something that could be addressed by INIT_WORK_ONSTACK(), but
rhashtable doesn't expose that control and probably isnt worth the
churn for just one user. Instead, dynamically allocate the
buckets_in_flight structure and avoid the splat that way.

Subject: [PATCH 1105/1451] bcachefs: allow writeback to fill bio completely

The bcachefs folio writeback code includes a bio full check as well
as a fixed size check to determine when to split off and submit
writeback I/O. The inclusive check of the latter against the limit
means that writeback can submit slightly prematurely. This is not a
functional problem, but results in unnecessarily split I/Os and
extent merging.

This can be observed with a buffered write sized exactly to the
current maximum value (1MB) and with key_merging_disabled=1. The
latter prevents the merge from the second write such that a
subsequent check of the extent list shows a 1020k extent followed by
a contiguous 4k extent.

The purpose for the fixed size check is also undocumented and
somewhat obscure. Lift this check into a new helper that wraps the
bio check, fix the comparison logic, and add a comment to document
the purpose and how we might improve on this in the future.

Subject: [PATCH 1106/1451] bcachefs: byte order swap
 bch_alloc_v4.fragmentation_lru field

A simple test to populate a filesystem on one CPU architecture and
fsck on an arch of the opposite byte order produces errors related
to the fragmentation LRU. This occurs because the 64-bit
fragmentation_lru field is not byte-order swapped when reads detect
that the on-disk/bset key values were written in opposite byte-order
of the current CPU.

Update the bch2_alloc_v4 swab callback to handle fragmentation_lru
as is done for other multi-byte fields. This doesn't affect existing
filesystems when accessed by CPUs of the same endianness because the
->swab() callback is only called when the bset flags indicate an
endianness mismatch between the CPU and on-disk data.

The bucket_offset field of bch_backpointer is a 40-bit bitfield, but the

when an on-disk fs is accessed from an opposite endian machine.

As it turns out, we already have an internal swab40() helper that is

header file and use it consistently in both places.

 JSET_NO_FLUSH journal entry

When we didn't find anything in the journal that we'd like to use, and
we're forced to use whatever we can find - that entry will have been a
JSET_NO_FLUSH entry with a garbage last_seq value, since it's not
normally used.

Initialize it to something sane, for bch2_fs_journal_start().

Subject: [PATCH 1112/1451] bcachefs: rebalance_work btree is not a snapshots
 btree

rebalance_work entries may refer to entries in the extents btree, which
is a snapshots btree, or they may also refer to entries in the reflink
btree, which is not.

Hence rebalance_work keys may use the snapshot field but it's not
required to be nonzero - add a new btree flag to reflect this.

BCACHEFS_DEBUG_TRANSACTIONS is useful, but it's too expensive to have on
by default - and it hasn't been coming up in bug reports.

Turn it off by default until we figure out a way to make it cheaper.

Subject: [PATCH 1115/1451] riscv: signal: handle syscall restart before
 get_signal

In the current riscv implementation, blocking syscalls like read() may
not correctly restart after being interrupted by ptrace. This problem
arises when the syscall restart process in arch_do_signal_or_restart()
is bypassed due to changes to the regs->cause register, such as an
ebreak instruction.

Steps to reproduce:
1. Interrupt the tracee process with PTRACE_SEIZE & PTRACE_INTERRUPT.
2. Backup original registers and instruction at new_pc.
3. Change pc to new_pc, and inject an instruction (like ebreak) to this
   address.
4. Resume with PTRACE_CONT and wait for the process to stop again after
   executing ebreak.
5. Restore original registers and instructions, and detach from the
   tracee process.
6. Now the read() syscall in tracee will return -1 with errno set to
   ERESTARTSYS.

Specifically, during an interrupt, the regs->cause changes from
EXC_SYSCALL to EXC_BREAKPOINT due to the injected ebreak, which is
inaccessible via ptrace so we cannot restore it. This alteration breaks
the syscall restart condition and ends the read() syscall with an
ERESTARTSYS error. According to include/linux/errno.h, it should never
be seen by user programs. X86 can avoid this issue as it checks the
syscall condition using a register (orig_ax) exposed to user space.
Arm64 handles syscall restart before calling get_signal, where it could
be paused and inspected by ptrace/debugger.

This patch adjusts the riscv implementation to arm64 style, which also
checks syscall using a kernel register (syscallno). It ensures the
syscall restart process is not bypassed when changes to the cause
register occur, providing more consistent behavior across various
architectures.

If these config not set, mmc can't run for jh7110, rootfs can't
be found when using SD card. So set CONFIG_MMC_DW=y like arm64
defconfig, and set CONFIG_MMC_DW_STARFIVE=y for starfive. Then
starfive vf2 board can start SD card rootfs with mainline defconfig
and dtb.

Subject: [PATCH 1118/1451] RISC-V: capitalise CMO op macros

The CMO op macros initially used lower case, as the original iteration
of the ALT_CMO_OP alternative stringified the first parameter to
finalise the assembly for the standard variant.
As a knock-on, the T-Head versions of these CMOs had to use mixed case
defines. Commit dd23e9535889 ("RISC-V: replace cbom instructions with
an insn-def") removed the asm construction with stringify, replacing it
an insn-def macro, rending the lower-case surplus to requirements.
As far as I can tell from a brief check, CBO_zero does not see similar
use and didn't require the mixed case define in the first place.
Replace the lower case characters now for consistency with other
insn-def macros in the standard and T-Head forms, and adjust the
callsites.

Subject: [PATCH 1119/1451] riscv: Improve PTDUMP to show RSW with non-zero
 value

RSW field can be used to encode 2 bits of software
defined information. Currently, PTDUMP only prints
"RSW" when its value is 1 or 3.

To fix this issue and improve the debugging experience
with PTDUMP, we redefine _PAGE_SPECIAL to its original
value and use _PAGE_SOFT as the RSW mask, allow it to
print the RSW with any non-zero value.

This patch also removes the val from the struct prot_bits
as it is no longer needed.

Subject: [PATCH 1128/1451] bcachefs: Break up bch2_journal_write()

Split up bch2_journal_write() to simplify locking:
 - bch2_journal_write_pick_flush(), which needs j->lock
 - bch2_journal_write_prep, which operates on the journal buffer to be
   written and will need the upcoming buf_lock for synchronization with
   the btree write buffer flush path

We're not supposed to have more than one btree_trans at a time in a
given thread - that causes recursive locking deadlocks.

Subject: [PATCH 1133/1451] bcachefs: Simplify, fix bch2_backpointer_get_key()

 - backpointer_not_found() checks backpointers_no_use_write_buffer, no
   need to do it inbackpointer_get_key().

 - always use backpointer_get_node() for pointers to nodes:
   backpointer_get_key() was sometimes returning the key from the root
   node unlocked.

Subject: [PATCH 1136/1451] s390/ap: rework to use irq info from ap queue
 status

This patch reworks the irq handling and reporting code
for the AP queue interrupt handling to always use the
irq info from the queue status.

Until now the interrupt status of an AP queue was stored
into a bool variable within the ap_queue struct. This
variable was set on a successful interrupt enablement
and cleared with kicking a reset. However, it may be
that the interrupt state is manipulated outband for
example by a hypervisor. This patch removes this variable
and instead the irq bit from the AP queue status which is
always reflecting the current irq state is used.

Subject: [PATCH 1137/1451] s390/ap: re-enable interrupt for AP queues

This patch introduces some code lines which check
for interrupt support enabled on an AP queue after
a reply has been received. This invocation has been
chosen as there is a good chance to have the queue
empty at that time. As the enablement of the irq
imples a state machine change the queue should not
have any pending requests or unreceived replies.

Subject: [PATCH 1138/1451] s390/ap: fix AP bus crash on early config change
 callback invocation

Fix kernel crash in AP bus code caused by very early invocation of the
config change callback function via SCLP.

After a fresh IML of the machine the crypto cards are still offline and
will get switched online only with activation of any LPAR which has the
card in it's configuration. A crypto card coming online is reported
to the LPAR via SCLP and the AP bus offers a callback function to get
this kind of information. However, it may happen that the callback is
invoked before the AP bus init function is complete. As the callback
triggers a synchronous AP bus scan, the scan may already run but some
internal states are not initialized by the AP bus init function resulting
in a crash like this:

This patch improves the ap_bus_force_rescan() function which is
invoked by the config change callback by checking if a first
initial AP bus scan has been done. If not, the force rescan request
is simple ignored. Anyhow it does not make sense to trigger AP bus
re-scans even before the very first bus scan is complete.

Subject: [PATCH 1139/1451] s390/perf: implement perf_callchain_user()

Daan De Meyer and Neal Gompa reported that s390 does not support perf user
stack unwinding.

This was never implemented since this requires user space to be compiled
with the -mbackchain compile option, which until now no distribution
did. However this is going to change with Fedora. Therefore provide a
perf_callchain_user() implementation.

Note that due to the way s390 sets up stack frames the provided call chains
can contain invalid values. This is especially true for the first stack
frame, where it is not possible to tell if the return address has been
written to the stack already or not.

Subject: [PATCH 1140/1451] s390: add USER_STACKTRACE support

Use the perf_callchain_user() code as blueprint to also add support for
USER_STACKTRACE. To describe how to use this cite the commit message of the
LoongArch implementation which came with commit 4d7bf939df08 ("LoongArch:
Add USER_STACKTRACE support"), but replace -fno-omit-frame-pointer option
with the s390 specific -mbackchain option:
====================================================================== To
get the best stacktrace output, you can compile your userspace programs
with frame pointers (at least glibc + the app you are tracing).

1, export "CC = gcc -mbackchain";
2, compile your programs with "CC";
3, use uprobe to get stacktrace output.

...
     echo 'p:malloc /usr/lib64/libc.so.6:0x0a4704 size=%r2:u64' > uprobe_events
     echo 'p:free /usr/lib64/libc.so.6:0x0a4d50 ptr=%r2:u64' >> uprobe_events
     echo 'comm == "demo"' > ./events/uprobes/malloc/filter
     echo 'comm == "demo"' > ./events/uprobes/free/filter
     echo 1 > ./options/userstacktrace
     echo 1 > ./options/sym-userobj

Subject: [PATCH 1141/1451] s390/zcrypt: don't report online if card or queue
 is in check-stop state

If a card or a queue is in check-stop state, it can't be used by
applications to perform crypto operations. Applications check the 'online'
sysfs attribute to check if a card or queue is usable.

Report a card or queue as offline in case it is in check-stop state.
Furthermore, don't allow to set a card or queue online, if it is in
check-stop state.

This is similar to when the card or the queue is in deconfigured state,
there it is also reported as being offline, and it can't be set online.

Subject: [PATCH 1142/1451] s390/ap: fix vanishing crypto cards in SE
 environment

A secure execution (SE, also known as confidential computing)
guest may see asynchronous errors on a crypto firmware queue.
The current implementation to gather information about cards
and queues in ap_queue_info() simple returns if an asynchronous
error is hanging on the firmware queue. If such a situation
happened and it was the only queue visible for a crypto card
within an SE guest, then the card vanished from sysfs as
the AP bus scan function refuses to hold a card without any
type information. As lszcrypt evaluates the sysfs such
a card vanished from the lszcrypt card listing and the
user is baffled and has no way to reset and thus clear the
pending asynchronous error.

This patch improves the named function to also evaluate GR2
of the TAPQ in case of asynchronous error pending. If there
is a not-null value stored in, the info is processed now.
In the end, a queue with pending asynchronous error does not
lead to a vanishing card any more.

 early boot code

The "cmma=" kernel command line parameter needs to be parsed early for
upcoming changes. Therefore move the parsing code.

Note that EX_TABLE handling of cmma_test_essa() needs to be open-coded,
since the early boot code doesn't have infrastructure for handling expected
exceptions.

Subject: [PATCH 1145/1451] s390/cmma: move set_page_stable() and friends to
 header file

In order to be usable for early boot code move the simple set_page_xxx()
function to header file. Also change the parameters, and the function names
slightly.

This is required since there aren't any struct pages available in early
boot code, and renaming of functions is done to make sure that all users
are converted to the new API.

Instead of a pointer to a struct page a virtual address is passed, and
instead of an order the number of pages for which the page state needs be
set.

Subject: [PATCH 1146/1451] s390/cmma: move arch_set_page_dat() to header file

In order to be usable for early boot code move the simple
arch_set_page_dat() function to header file, and add its counter-part
arch_set_page_nodat(). Also change the parameters, and the function name
slightly.

This is required since there aren't any struct pages available in early
boot code, and renaming of functions is done to make sure that all users
are converted to the new API.

Instead of a pointer to a struct page a virtual address is passed, and
instead of an order the number of pages for which the page state needs be
set.

Subject: [PATCH 1147/1451] s390/cmma: rework no-dat handling

Rework the way physical pages are set no-dat / dat:

The old way is:

- Rely on that all pages are initially marked "dat"
- Allocate page tables for the kernel mapping
- Enable dat
- Walk the whole kernel mapping and set PG_arch_1 bit in all struct pages
  that belong to pages of kernel page tables
- Walk all struct pages and test and clear the PG_arch_1 bit. If the bit is
  not set, set the page state to no-dat
- For all subsequent page table allocations, set the page state to dat
  (remove the no-dat state) on allocation time

Change this rather complex logic to a simpler approach:

- Set the whole physical memory (all pages) to "no-dat"
- Explicitly set those page table pages to "dat" which are part of the
  kernel image (e.g. swapper_pg_dir)
- For all subsequent page table allocations, set the page state to dat
  (remove the no-dat state) on allocation time

In result the code is simpler, and this also allows to get rid of one
odd usage of the PG_arch_1 bit.

Subject: [PATCH 1148/1451] s390/mm: use full 4KB page for 2KB PTE

Cease using 4KB pages to host two 2KB PTEs. That greatly
simplifies the memory management code at the expense of
page tables memory footprint.

Instead of two PTEs per 4KB page use only upper half of
the parent page for a single PTE. With that the list of
half-used pages pgtable_list becomes unneeded.

Further, the upper byte of the parent page _refcount
counter does not need to be used for fragments tracking
and could be left alone.

Commit 8211dad62798 ("s390: add pte_free_defer() for
pgtables sharing page") introduced the use of PageActive
flag to coordinate a deferred free with 2KB page table
fragments tracking. Since there is no tracking anymore,
there is no need for using PageActive flag.

- * A 2KB-pgtable is either upper or lower half of a normal page.

- *
- * Whenever possible the parent page for a new 2KB-pgtable is picked
- * from the list of partially allocated pages mm_context_t::pgtable_list.
- * In case the list is empty a new parent page is allocated and added to

- *
- * When a parent page gets fully allocated it contains 2KB-pgtables in both

- *
- * When 2KB-pgtable is freed from to fully allocated parent page that
- * page turns partially allocated and added to mm_context_t::pgtable_list.
- *
- * If 2KB-pgtable is freed from the partially allocated parent page that
- * page turns unused and gets removed from mm_context_t::pgtable_list.
- * Furthermore, the unused parent page is released.
- *
- * As follows from the above, no unallocated or fully allocated parent
- * pages are contained in mm_context_t::pgtable_list.
- *
- * The upper byte (bits 24-31) of the parent page _refcount is used
- * for tracking contained 2KB-pgtables and has the following format:

- *   PP  AA
- * 01234567    upper byte (bits 24-31) of struct page::_refcount

- *   ||  +---- lower 2KB-pgtable is allocated
- *   |+------- upper 2KB-pgtable is pending for removal
- *   +-------- lower 2KB-pgtable is pending for removal
- *
- * (See commit 620b4e903179 ("s390: use _refcount for pgtables") on why
- * using _refcount is possible).
- *
- * When 2KB-pgtable is allocated the corresponding AA bit is set to 1.
- * The parent page is either:
- *   - added to mm_context_t::pgtable_list in case the second half of the
- *     parent page is still unallocated;
- *   - removed from mm_context_t::pgtable_list in case both hales of the
- *     parent page are allocated;
- * These operations are protected with mm_context_t::lock.
- *
- * When 2KB-pgtable is deallocated the corresponding AA bit is set to 0
- * and the corresponding PP bit is set to 1 in a single atomic operation.
- * Thus, PP and AA bits corresponding to the same 2KB-pgtable are mutually
- * exclusive and may never be both set to 1!
- * The parent page is either:
- *   - added to mm_context_t::pgtable_list in case the second half of the
- *     parent page is still allocated;
- *   - removed from mm_context_t::pgtable_list in case the second half of
- *     the parent page is unallocated;
- * These operations are protected with mm_context_t::lock.
- *
- * It is important to understand that mm_context_t::lock only protects
- * mm_context_t::pgtable_list and AA bits, but not the parent page itself
- * and PP bits.
- *
- * Releasing the parent page happens whenever the PP bit turns from 1 to 0,
- * while both AA bits and the second PP bit are already unset. Then the
- * parent page does not contain any 2KB-pgtable fragment anymore, and it has
- * also been removed from mm_context_t::pgtable_list. It is safe to release
- * the page therefore.
- *
- * PGSTE memory spaces use full 4KB-pgtables and do not need most of the
- * logic described above. Both AA bits are set to 1 to denote a 4KB-pgtable
- * while the PP bits are never used, nor such a page is added to or removed
- * from mm_context_t::pgtable_list.
- *
- * pte_free_defer() overrides those rules: it takes the page off pgtable_list,
- * and prevents both 2K fragments from being reused. pte_free_defer() has to
- * guarantee that its pgtable cannot be reused before the RCU grace period
- * has elapsed (which page_table_free_rcu() does not actually guarantee).
- * But for simplicity, because page->rcu_head overlays page->lru, and because
- * the RCU callback might not be called before the mm_context_t has been freed,
- * pte_free_defer() in this implementation prevents both fragments from being
- * reused, and delays making the call to RCU until both fragments are freed.

CRSTs always have size of four pages, while 2KB-size page tables

Subject: [PATCH 1151/1451] riscv: provide riscv-specific is_trap_insn()
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

uprobes expects is_trap_insn() to return true for any trap instructions,
not just the one used for installing uprobe. The current default
implementation only returns true for 16-bit c.ebreak if C extension is
enabled. This can confuse uprobes if a 32-bit ebreak generates a trap
exception from userspace: uprobes asks is_trap_insn() who says there is no
trap, so uprobes assume a probe was there before but has been removed, and
return to the trap instruction. This causes an infinite loop of entering
and exiting trap handler.

Instead of using the default implementation, implement this function
speficially for riscv with checks for both ebreak and c.ebreak.

Subject: [PATCH 1156/1451] riscv: vdso.lds.S: remove hardcoded 0x800 .text
 start addr

I believe the hardcoded 0x800 and related comments come from the long
history VDSO_TEXT_OFFSET in x86 vdso code, but commit 5b9304933730
("x86 vDSO: generate vdso-syms.lds") and commit f6b46ebf904f ("x86
vDSO: new layout") removes the comment and hard coding for x86.

Similar as x86 and other arch, riscv doesn't need the rigid layout
using VDSO_TEXT_OFFSET since it "no longer matters to the kernel".
so we could remove the hard coding now, and removing it brings a
small vdso.so and aligns with other architectures.

Also, having enough separation between data and text is important for
I-cache, so similar as x86, move .note, .eh_frame_hdr, and .eh_frame
between .rodata and .text.

Subject: [PATCH 1158/1451] gfs2: Get rid of gfs2_alloc_blocks generation
 parameter

Get rid of the generation parameter of gfs2_alloc_blocks(): we only ever
set the generation of the current inode while creating it, so do so
directly.

Subject: [PATCH 1159/1451] gfs2: Minor gfs2_write_jdata_batch PAGE_SIZE
 cleanup

In gfs2_write_jdata_batch(), to compute the number of blocks, compute
the total size of the folio batch instead of the number of pages it
contains.  Not a functional change.

Note that we don't currently allow mounting filesystems with a block
size bigger than the page size.  We could change that after converting
the page cache to folios.  The page cache would then only contain
block-size or bigger folios, so rounding wouldn't become an issue here.

Function gfs2_lookup_simple() is used for looking up inodes in the

match its purpose.  Clean the function up a little on the way.

From 0b2355fe91ac3756a9e29c8b833ba33f9affb520 Mon Sep 17 00:00:00 2001
From: Andreas Gruenbacher <agruenba@redhat.com>
Date: Mon, 9 Oct 2023 18:49:31 +0200
Subject: [PATCH 1163/1451] gfs2: No longer use 'extern' in function
 declarations

For non-static function declarations, external linkage is implied and
the 'extern' keyword isn't needed.  Some static checkers complain about
the overuse of 'extern', so clean up all the function declarations.

In addition, remove 'extern' from the definition of
free_local_statfs_inodes(); it isn't needed there, either.

Subject: [PATCH 1164/1451] gfs2: fs: derive f_fsid from s_uuid

gfs2 already has optional persistent uuid.

Use that uuid to report f_fsid in statfs(2), same as ext2/ext4/zonefs.

This allows gfs2 to be monitored by fanotify filesystem watch.
for example, with inotify-tools 4.23.8.0, the following command can be
used to watch changes over entire filesystem:

  fsnotifywatch --filesystem /mnt/gfs2

Subject: [PATCH 1165/1451] gfs2: Silence "suspicious RCU usage in
 gfs2_permission" warning

Commit 0abd1557e21c added rcu_dereference() for dereferencing ip->i_gl
in gfs2_permission.  This now causes lockdep to complain when
gfs2_permission is called in non-RCU context:

    WARNING: suspicious RCU usage in gfs2_permission

Switch to rcu_dereference_check() and check for the MAY_NOT_BLOCK flag
to shut up lockdep when we know that dereferencing ip->i_gl is safe.

Fixes: 0abd1557e21c ("gfs2: fix an oops in gfs2_permission")

Subject: [PATCH 1166/1451] gfs2: Fix slab-use-after-free in gfs2_qd_dealloc

In gfs2_put_super(), whether withdrawn or not, the quota should
be cleaned up by gfs2_quota_cleanup().

Otherwise, struct gfs2_sbd will be freed before gfs2_qd_dealloc (rcu
callback) has run for all gfs2_quota_data objects, resulting in
use-after-free.

Also, gfs2_destroy_threads() and gfs2_quota_cleanup() is already called
by gfs2_make_fs_ro(), so in gfs2_put_super(), after calling
gfs2_make_fs_ro(), there is no need to call them again.

Subject: [PATCH 1168/1451] gfs2: don't withdraw if init_threads() got
 interrupted

In gfs2_fill_super(), when mounting a gfs2 filesystem is interrupted,
kthread_create() can return -EINTR.  When that happens, we roll back
what has already been done and abort the mount.

Since commit 62dd0f98a0e5 ("gfs2: Flag a withdraw if init_threads()
fails), we are calling gfs2_withdraw_delayed() in gfs2_fill_super();
first via gfs2_make_fs_rw(), then directly.  But gfs2_withdraw_delayed()
only marks the filesystem as withdrawing and relies on a caller further
up the stack to do the actual withdraw, which doesn't exist in the
gfs2_fill_super() case.  Because the filesystem is marked as withdrawing
/ withdrawn, function gfs2_lm_unmount() doesn't release the dlm
lockspace, so when we try to mount that filesystem again, we get:

    gfs2: fsid=gohan:gohan0: Trying to join cluster "lock_dlm", "gohan:gohan0"
    gfs2: fsid=gohan:gohan0: dlm_new_lockspace error -17

Since commit b77b4a4815a9 ("gfs2: Rework freeze / thaw logic"), the
deadlock this gfs2_withdraw_delayed() call was supposed to work around
cannot occur anymore because freeze_go_callback() won't take the
sb->s_umount semaphore unconditionally anymore, so we can get rid of the
gfs2_withdraw_delayed() in gfs2_fill_super() entirely.

This patch moves dma_addressing_limited() out of line, serving as a
preliminary step to prevent the introduction of a new publicly accessible
low-level helper when validating whether all system RAM is mapped within
the DMA mapping range.

Subject: [PATCH 1173/1451] dma-mapping: fix dma_addressing_limited() if
 dma_range_map can't cover all system RAM

There is an unusual case that the range map covers right up to the top
of system RAM, but leaves a hole somewhere lower down. Then it prevents
the nvme device dma mapping in the checking path of phys_to_dma() and
causes the hangs at boot.

E.g. On an Armv8 Ampere server, the dsdt ACPI table is:
 Method (_DMA, 0, Serialized)  // _DMA: Direct Memory Access
            {
                Name (RBUF, ResourceTemplate ()
                {
                    QWordMemory (ResourceConsumer, PosDecode, MinFixed,
MaxFixed, Cacheable, ReadWrite,
                        0x0000000000000000, // Granularity
                        0x0000000000000000, // Range Minimum
                        0x00000000FFFFFFFF, // Range Maximum
                        0x0000000000000000, // Translation Offset
                        0x0000000100000000, // Length
                        ,, , AddressRangeMemory, TypeStatic)
                    QWordMemory (ResourceConsumer, PosDecode, MinFixed,

                        0x0000000010000000, // Length
                        ,, , AddressRangeMemory, TypeStatic)
                    QWordMemory (ResourceConsumer, PosDecode, MinFixed,
MaxFixed, Cacheable, ReadWrite,
                        0x0000000000000000, // Granularity
                        0x0000007000000000, // Range Minimum
                        0x000003FFFFFFFFFF, // Range Maximum
                        0x0000000000000000, // Translation Offset
                        0x0000039000000000, // Length
                        ,, , AddressRangeMemory, TypeStatic)
                })

But the System RAM ranges are:
cat /proc/iomem |grep -i ram
90000000-91ffffff : System RAM
92900000-fffbffff : System RAM
880000000-fffffffff : System RAM
8800000000-bff5990fff : System RAM
bff59d0000-bff5a4ffff : System RAM
bff8000000-bfffffffff : System RAM
So some RAM ranges are out of dma_range_map.

Fix it by checking whether each of the system RAM resources can be
properly encompassed within the dma_range_map.

Getting the following splat [1] with CONFIG_DEBUG_NET=y and this
reproducer [2]. Problem seems to be that classifiers clear 'struct

__kfree_skb_reason() due to reason being 'SKB_NOT_DROPPED_YET' (0).

Fixed by disambiguating a legit error from a verdict with a bogus drop_reason

What happens is that inside most classifiers the tcf_result is copied over
from a filter template e.g. *res = f->res which then implicitly overrides
the prior SKB_DROP_REASON_TC_{INGRESS,EGRESS} default drop code which was
set via sch_handle_{ingress,egress}() for kfree_skb_reason().

Commit text above copied verbatim from Daniel. The general idea of the patch
is not very different from what Ido originally posted but instead done at the
cls_api codepath.

Subject: [PATCH 1176/1451] octeontx2-pf: Free pending and dropped SQEs

On interface down, the pending SQEs in the NIX get dropped
or drained out during SMQ flush. But skb's pointed by these
SQEs never get free or updated to the stack as respective CQE
never get added.
This patch fixes the issue by freeing all valid skb's in SQ SG list.

Subject: [PATCH 1177/1451] tcp: Fix SYN option room calculation for TCP-AO.

When building SYN packet in tcp_syn_options(), MSS, TS, WS, and
SACKPERM are used without checking the remaining bytes in the
options area.

To keep that logic as is, we limit the TCP-AO MAC length in
tcp_ao_parse_crypto().  Currently, the limit is calculated as below.

  MAX_TCP_OPTION_SPACE - TCPOLEN_TSTAMP_ALIGNED
                       - TCPOLEN_WSCALE_ALIGNED
                       - TCPOLEN_SACKPERM_ALIGNED

This looks confusing as (1) we pack SACKPERM into the leading
2-bytes of the aligned 12-bytes of TS and (2) TCPOLEN_MSS_ALIGNED
is not used.  Fortunately, the calculated limit is not wrong as
TCPOLEN_SACKPERM_ALIGNED and TCPOLEN_MSS_ALIGNED are the same value.

However, we should use the proper constant in the formula.

  MAX_TCP_OPTION_SPACE - TCPOLEN_MSS_ALIGNED
                       - TCPOLEN_TSTAMP_ALIGNED
                       - TCPOLEN_WSCALE_ALIGNED

Subject: [PATCH 1179/1451] net/smc: fix dangling sock under state
 SMC_APPFINCLOSEWAIT

Considering scenario:

				smc_cdc_rx_handler
__smc_release
				sock_set_flag
smc_close_active()
sock_set_flag

__set_bit(DEAD)			__set_bit(DONE)

Dues to __set_bit is not atomic, the DEAD or DONE might be lost.
if the DEAD flag lost, the state SMC_CLOSED  will be never be reached
in smc_close_passive_work:

if (sock_flag(sk, SOCK_DEAD) &&
	smc_close_sent_any_close(conn)) {
	sk->sk_state = SMC_CLOSED;
} else {
	/* just shutdown, but not yet closed locally */
	sk->sk_state = SMC_APPFINCLOSEWAIT;
}

Replace sock_set_flags or __set_bit to set_bit will fix this problem.
Since set_bit is atomic.

This patch re-fix the issues mentioned by commit 22a825c541d7
("net/smc: fix NULL sndbuf_desc in smc_cdc_tx_handler()").

Blocking sending message do solve the issues though, but it also
prevents the peer to receive the final message. Besides, in logic,
whether the sndbuf_desc is NULL or not have no impact on the processing
of cdc message sending.

Hence that, this patch allows the cdc message sending but to check the
sndbuf_desc with care in smc_cdc_tx_handler().

 component probe

The HDMI hotplug callback to the hdmi-codec is currently registered when
jack is set.

The hotplug not only serves to report the ASoC jack state but also to get
the ELD. It should be registered when the component probes instead, so it
does not depend on the card driver registering a jack for the HDMI to
properly report the ELD.

Subject: [PATCH 1186/1451] drm/i915: Bump GLK CDCLK frequency when driving
 multiple pipes
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

On GLK CDCLK frequency needs to be at least 2*96 MHz when accessing
the audio hardware. Currently we bump the CDCLK frequency up
temporarily (if not high enough already) whenever audio hardware
is being accessed, and drop it back down afterwards.

With a single active pipe this works just fine as we can switch
between all the valid CDCLK frequencies by changing the cd2x
divider, which doesn't require a full modeset. However with
multiple active pipes the cd2x divider trick no longer works,
and thus we end up blinking all displays off and back on.

To avoid this let's just bump the CDCLK frequency to >=2*96MHz
whenever multiple pipes are active. The downside is slightly
higher power consumption, but that seems like an acceptable
tradeoff. With a single active pipe we can stick to the current
more optiomal (from power comsumption POV) behaviour.

fine-grained flush of the TLB.

Subject: [PATCH 1192/1451] riscv: Improve flush_tlb_range() for hugetlb pages

flush_tlb_range() uses a fixed stride of PAGE_SIZE and in its current form,
when a hugetlb mapping needs to be flushed, flush_tlb_range() flushes the
whole tlb: so set a stride of the size of the hugetlb mapping in order to
only flush the hugetlb mapping. However, if the hugepage is a NAPOT region,
all PTEs that constitute this mapping must be invalidated, so the stride
size must actually be the size of the PTE.

Note that THPs are directly handled by flush_pmd_tlb_range().

Subject: [PATCH 1193/1451] riscv: Make __flush_tlb_range() loop over pte
 instead of flushing the whole tlb

Currently, when the range to flush covers more than one page (a 4K page or
a hugepage), __flush_tlb_range() flushes the whole tlb. Flushing the whole
tlb comes with a greater cost than flushing a single entry so we should
flush single entries up to a certain threshold so that:
threshold * cost of flushing a single entry < cost of flushing the whole
tlb.

Subject: [PATCH 1194/1451] riscv: Improve flush_tlb_kernel_range()

This function used to simply flush the whole tlb of all harts, be more
subtile and try to only flush the range.

The problem is that we can only use PAGE_SIZE as stride since we don't know
the size of the underlying mapping and then this function will be improved
only if the size of the region to flush is < threshold * PAGE_SIZE.

When flashing loader.bin for K210 using kflash:

    [ERROR] This is an ELF file and cannot be programmed to flash directly: arch/riscv/boot/loader.bin

Before, loader.bin relied on "OBJCOPYFLAGS := -O binary" in the main
RISC-V Makefile to create a boot image with the right format.  With this
removed, the image is now created in the wrong (ELF) format.

Fix this by adding an explicit rule.

Content-Transfer-Encoding: 8bit

For the sake of coherency, use local labels in assembly when
applicable. This also avoid kprobes being confused when applying a
kprobe since the size of function is computed by checking where the
next visible symbol is located. This might end up in computing some
function size to be way shorter than expected and thus failing to apply
kprobes to the specified offset.

Subject: [PATCH 1208/1451] riscv: Use SYM_*() assembly macros instead of
 deprecated ones
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

ENTRY()/END()/WEAK() macros are deprecated and we should make use of the
new SYM_*() macros [1] for better annotation of symbols. Replace the
deprecated ones with the new ones and fix wrong usage of END()/ENDPROC()
to correctly describe the symbols.

Subject: [PATCH 1211/1451] io_uring: do not allow multishot read to set addr
 or len

For addr: this field is not used, since buffer select is forced.
But by forcing it to be zero it leaves open future uses of the field.

len is actually usable, you could imagine that you want to receive
multishot up to a certain length.
However right now this is not how it is implemented, and it seems
safer to force this to be zero.

Subject: [PATCH 1212/1451] io_uring: do not clamp read length for multishot
 read

When doing a multishot read, the code path reuses the old read
paths. However this breaks an assumption built into those paths,
namely that struct io_rw::len is available for reuse by __io_import_iovec.

For multishot this results in len being set for the first receive
call, and then subsequent calls are clamped to that buffer length
incorrectly.

Instead keep len as zero after recycling buffers, to reuse the full
buffer size of the next selected buffer.

Subject: [PATCH 1216/1451] ice: Fix SRIOV LAG disable on non-compliant
 aggregate

If an attribute of an aggregate interface disqualifies it from supporting
SRIOV, the driver will unwind the SRIOV support.  Currently the driver is
clearing the feature bit for all interfaces in the aggregate, but this is
not allowing the other interfaces to unwind successfully on driver unload.

Only clear the feature bit for the interface that is currently unwinding.

Subject: [PATCH 1219/1451] ice: Fix VF-VF direction matching in drop rule in
 switchdev

When adding a drop rule on a VF, rule direction is not being set, which
results in it always being set to ingress (ICE_ESWITCH_FLTR_INGRESS
equals 0). Because of this, drop rules added on port representors don't
match any packets.

To fix it, set rule direction in drop action to egress when netdev is a
port representor, otherwise set it to ingress.

Subject: [PATCH 1220/1451] tg3: power down device only on SYSTEM_POWER_OFF

Dell R650xs servers hangs on reboot if tg3 driver calls
tg3_power_down.

This happens only if network adapters (BCM5720 for R650xs) were
initialized using SNP (e.g. by booting ipxe.efi).

The actual problem is on Dell side, but this fix allows servers
to come back alive after reboot.

Subject: [PATCH 1221/1451] idpf: fix potential use-after-free in idpf_tso()

skb_cow_head() can change skb->head (and thus skb_shinfo(skb))

We must not cache skb_shinfo(skb) before skb_cow_head().

Fixes: 6818c4d5b3c2 ("idpf: add splitq start_xmit")

For now, tlb_flush() simply calls flush_tlb_mm() which results in a
flush of the whole TLB. So let's use mmu_gather fields to provide a more
fine-grained flush of the TLB.

Subject: [PATCH 1225/1451] riscv: Improve flush_tlb_range() for hugetlb pages

flush_tlb_range() uses a fixed stride of PAGE_SIZE and in its current form,
when a hugetlb mapping needs to be flushed, flush_tlb_range() flushes the
whole tlb: so set a stride of the size of the hugetlb mapping in order to
only flush the hugetlb mapping. However, if the hugepage is a NAPOT region,
all PTEs that constitute this mapping must be invalidated, so the stride
size must actually be the size of the PTE.

Note that THPs are directly handled by flush_pmd_tlb_range().

Subject: [PATCH 1226/1451] riscv: Make __flush_tlb_range() loop over pte
 instead of flushing the whole tlb

Currently, when the range to flush covers more than one page (a 4K page or
a hugepage), __flush_tlb_range() flushes the whole tlb. Flushing the whole
tlb comes with a greater cost than flushing a single entry so we should
flush single entries up to a certain threshold so that:
threshold * cost of flushing a single entry < cost of flushing the whole
tlb.

Subject: [PATCH 1227/1451] riscv: Improve flush_tlb_kernel_range()

This function used to simply flush the whole tlb of all harts, be more
subtile and try to only flush the range.

The problem is that we can only use PAGE_SIZE as stride since we don't know
the size of the underlying mapping and then this function will be improved
only if the size of the region to flush is < threshold * PAGE_SIZE.

Subject: [PATCH 1233/1451] arm64/arm: arm_pmuv3: perf: Don't truncate 64-bit
 registers

The driver used to truncate several 64-bit registers such as PMCEID[n]
registers used to describe whether architectural and microarchitectural
events in range 0x4000-0x401f exist. Due to discarding the bits, the
driver made the events invisible, even if they existed.

Moreover, PMCCFILTR and PMCR registers have additional bits in the upper
32 bits. This patch makes them available although they aren't currently
used. Finally, functions handling PMXEVCNTR and PMXEVTYPER registers are
removed as they not being used at all.

MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

OMAP2_VRFB is a bool, so the vrfb driver can never be compiled as a
module. With that __exit_p(vrfb_remove) always evaluates to NULL and
vrfb_remove() is unused.

If the driver was compilable as a module, it would fail to build because
the type of vrfb_remove() isn't compatible with struct
platform_driver::remove(). (The former returns void, the latter int.)

Subject: [PATCH 1241/1451] fbdev: viafb: use new array-copying-wrapper

viafbdev.c utilizes memdup_user() to copy an array from userspace.

There is a new wrapper, specifically designed for copying arrays. Use
this one instead.

Commit 4af5f2e03013 ("nbd: use blk_mq_alloc_disk and
blk_cleanup_disk") cleans up disk by blk_cleanup_disk() and it won't set
disk->private_data as NULL as before. UAF may be triggered in nbd_open()
if someone tries to open nbd device right after nbd_put() since nbd has
been free in nbd_dev_remove().

Fix this by implementing ->free_disk and free private data in it.

If one of the underlying disks of raid or dm is set to read-only, then
each io will generate new log, which will cause message storm. This
environment is indeed problematic, however we can't make sure our
naive custormer won't do this, hence use pr_warn_ratelimited() to
prevent message storm in this case.

Subject: [PATCH 1252/1451] drm/amd/display: decouple dmcub execution to reduce
 lock granularity

[Why]
On some systems dmub commands run at high IRQ, so long running
commands will block other interrupts.

[How]
Decouple wait_for_idle from dmcub queue/execute/wait.

[why]
To help isolate static screen and
video playback tests, we want to enable
an IPS option to allow IPS only on D3 cycle.

[How]
Add new translation to match the SCR update. Keep old translation for
backwards compatibility.

It's useful to disable the recovery mechanism when debugging replay
desync errors.

MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

[Why]
For Replay, if we receive HPD, it doesn’t need to reboot the display.
We don’t need to return anything exactly.

[How]
Return nothing just because we don’t need to reboot the display.

Subject: [PATCH 1264/1451] drm/amd/display: Fix OTG disable workaround logic

[Why]
DENTIST was hanging when performing DISPCLK update with OTG enabled, as
OTG disable workaround was not executing.

[How]
Workaround was checking against current_state before running, but when
called from optimize_bandwidth (safe_to_lower), we should be checking
against context instead.

Subject: [PATCH 1270/1451] drm/amd/display: Create optc.h file

For all the components that participate in DCN architecture, there is a
header in the dc/inch/hw. For some reason, OPTC broke this pattern and
added all the primary functions/structs associated with that in the
dcn10_optc.h file. For consistency's sake, this commit introduces a new
optc.h file and extracts the code from dcn10_optc to this new file.

 applying minimal transition

[why]
There is a case when we are switching from ODM combine to Subvp where
minimal transition based off subvp state is required. In thise case, we
need to save and restore mall state when applying minimal transition.

Subject: [PATCH 1275/1451] drm/amd/display: Enable physymclk RCO

[Why]
Enable the last of the RCO options for dcn35

[How]
Breakout RCO from dccg35_set_physymclk so that
physymclk RCO can be set in dccg_init without
disabling physymclk

[Description]
- Similar to FPO, SubVP should also force cursor P-State
  allow instead of relying on natural assertion
- Implement code path to force and unforce cursor P-State
  allow for SubVP

Subject: [PATCH 1277/1451] drm/amd/display: Fix handling duplicate planes on
 one stream

[why]
DML2 does not handle the case when we have
a single stream sourcing 2 or more planes
that are duplicates of one another. To properly
handle this scenario, pipe index to plane index
mapping is used to decide which plane is being
processed and programmed.

[how]
Create static array of pipe index to plane index map.

Subject: [PATCH 1278/1451] drm/amd/display: Set stream's DP test pattern upon
 test request

[Why]
A recent refactor of DC's DP test pattern automation code requires the
DC stream's test pattern and test pattern color space fields to be
correctly populated before calling dc_link_dp_set_test_pattern.

[How]
Populate stream's test pattern type and color space fields before
calling into DC to program DP test pattern.

Subject: [PATCH 1280/1451] drm/amdgpu: Fix sdma 4.4.2 doorbell rptr/wptr init

Doorbell rptr/wptr can be set through multiple ways including direct
register initialization. Disable doorbell during hw_fini once the ring
is disabled so that during next module reload direct initialization
takes effect. Also, move the direct initialization after minor update is
set to 1 since rptr/wptr are reinitialized back to 0 which could be
lower than the previous doorbell value (ex: cases like module reload).

Subject: [PATCH 1287/1451] nvme: common: make keyring and auth separate
 modules

When only the keyring module is included but auth is not, modpost
complains about the lack of a module license tag:

ERROR: modpost: missing MODULE_LICENSE() in drivers/nvme/common/nvme-common.o

Address this by making both modules buildable standalone,
removing the now unnecessary CONFIG_NVME_COMMON symbol
in the process.

Also, now that NVME_KEYRING config symbol can be either a module or
built-in, the stubs need to check for '#if IS_ENABLED' rather than a
simple '#ifdef'.

on physical hardware which uses less physical address bits, but in

Subject: [PATCH 1290/1451] tg3: Fix the TX ring stall

The TX ring maintained by the tg3 driver can end up in the state, when it
has packets queued for sending but the NIC hardware is not informed, so no
progress is made. This leads to a multi-second interruption in network
traffic followed by dev_watchdog() firing and resetting the queue.

The specific sequence of steps is:

1. tg3_start_xmit() is called at least once and queues packet(s) without
   updating tnapi->prodmbox (netdev_xmit_more() returns true)
2. tg3_start_xmit() is called with an SKB which causes tg3_tso_bug() to be
   called.
3. tg3_tso_bug() determines that the SKB is too large, ...

        if (unlikely(tg3_tx_avail(tnapi) <= frag_cnt_est)) {

   ... stops the queue, and returns NETDEV_TX_BUSY:

        netif_tx_stop_queue(txq);
        ...
        if (tg3_tx_avail(tnapi) <= frag_cnt_est)
                return NETDEV_TX_BUSY;

4. Since all tg3_tso_bug() call sites directly return, the code updating
   tnapi->prodmbox is skipped.

5. The queue is stuck now. tg3_start_xmit() is not called while the queue
   is stopped. The NIC is not processing new packets because
   tnapi->prodmbox wasn't updated. tg3_tx() is not called by
   tg3_poll_work() because the all TX descriptions that could be freed has
   been freed:

        /* run TX completion thread */
        if (tnapi->hw_status->idx[0].tx_consumer != tnapi->tx_cons) {
                tg3_tx(tnapi);

6. Eventually, dev_watchdog() fires triggering a reset of the queue.

This fix makes sure that the tnapi->prodmbox update happens regardless of
the reason tg3_start_xmit() returned.

Subject: [PATCH 1291/1451] tcp: Fix -Wc23-extensions in tcp_options_write()

Clang warns (or errors with CONFIG_WERROR=y) when CONFIG_TCP_AO is set:

  net/ipv4/tcp_output.c:663:2: error: label at end of compound statement is a C23 extension [-Werror,-Wc23-extensions]
    663 |         }
        |         ^
  1 error generated.

On earlier releases (such as clang-11, the current minimum supported
version for building the kernel) that do not support C23, this was a
hard error unconditionally:

  net/ipv4/tcp_output.c:663:2: error: expected statement
          }
          ^
  1 error generated.

While adding a semicolon after the label would resolve this, it is more
in line with the kernel as a whole to refactor this block into a
standalone function, which means the goto a label construct can just be
replaced with a return statement. Do so to resolve the warning.

Closes: https://github.com/ClangBuiltLinux/linux/issues/1953

Subject: [PATCH 1292/1451] vsock/virtio: remove socket from connected/bound
 list on shutdown

If the same remote peer, using the same port, tries to connect
to a server on a listening port more than once, the server will
reject the connection, causing a "connection reset by peer"
error on the remote peer. This is due to the presence of a
dangling socket from a previous connection in both the connected
and bound socket lists.
The inconsistency of the above lists only occurs when the remote
peer disconnects and the server remains active.

This bug does not occur when the server socket is closed:
virtio_transport_release() will eventually schedule a call to
virtio_transport_do_close() and the latter will remove the socket
from the bound and connected socket lists and clear the sk_buff.

However, virtio_transport_do_close() will only perform the above
actions if it has been scheduled, and this will not happen
if the server is processing the shutdown message from a remote peer.

To fix this, introduce a call to vsock_remove_sock()
when the server is handling a client disconnect.
This is to remove the socket from the bound and connected socket
lists without clearing the sk_buff.

Subject: [PATCH 1296/1451] net: phylink: initialize carrier state at creation

Background: Turris Omnia (Armada 385); eth2 (mvneta) connected to SFP bus;
SFP module is present, but no fiber connected, so definitely no carrier.

After booting, eth2 is down, but netdev LED trigger surprisingly reports
link active. Then, after "ip link set eth2 up", the link indicator goes
away - as I would have expected it from the beginning.

It turns out, that the default carrier state after netdev creation is
"carrier ok". Some ethernet drivers explicitly call netif_carrier_off
during probing, others (like mvneta) don't - which explains the current
behaviour: only when the device is brought up, phylink_start calls
netif_carrier_off.

Fix this for all drivers using phylink, by calling netif_carrier_off in
phylink_create.

Fixes: 089381b27abe ("leds: initial support for Turris Omnia LEDs")

Subject: [PATCH 1297/1451] riscv: Avoid unaligned access when relocating
 modules

With the C-extension regular 32bit instructions are not
necessarily aligned on 4-byte boundaries. RISC-V instructions
are in fact an ordered list of 16bit little-endian
"parcels", so access the instruction as such.

This should also make the code work in case someone builds
a big-endian RISC-V machine.

From 28ea54bade76e2d47cb8cdb96e427cfb90d3eea7 Mon Sep 17 00:00:00 2001
From: Palmer Dabbelt <palmer@rivosinc.com>
Date: Tue, 7 Nov 2023 07:55:29 -0800
Subject: [PATCH 1300/1451] RISC-V: Don't rely on positional structure
 initialization

Without this I get a bunch of warnings along the lines of

    arch/riscv/kernel/module.c:535:26: error: positional initialization of field in 'struct' declared with 'designated_init' attribute [-Werror=designated-init]
      535 |         [R_RISCV_32] = { apply_r_riscv_32_rela },

This just mades the member initializers explicit instead of positional.
I also aligned some of the table, but mostly just to make the batch
editing go faster.

Fixes: b51fc88cb35e ("Merge patch series "riscv: Add remaining module relocations and tests"")

Subject: [PATCH 1301/1451] RISC-V: Show accurate per-hart isa in /proc/cpuinfo

In /proc/cpuinfo, most of the information we show for each processor is
specific to that hart: marchid, mvendorid, mimpid, processor, hart,
compatible, and the mmu size. But the ISA string gets filtered through a
lowest common denominator mask, so that if one CPU is missing an ISA
extension, no CPUs will show it.

Now that we track the ISA extensions for each hart, let's report ISA
extension info accurately per-hart in /proc/cpuinfo. We cannot change
the "isa:" line, as usermode may be relying on that line to show only
the common set of extensions supported across all harts. Add a new "hart
isa" line instead, which reports the true set of extensions for that
hart.

+"isa" and "hart isa" lines in /proc/cpuinfo
+-------------------------------------------
+
+The "isa" line in /proc/cpuinfo describes the lowest common denominator of
+RISC-V ISA extensions recognized by the kernel and implemented on all harts. The
+"hart isa" line, in contrast, describes the set of extensions recognized by the
+kernel on the particular hart being described, even if those extensions may not
+be present on all harts in the system.
+
+In both lines, the presence of an extension guarantees only that the hardware
+has the described capability. Additional kernel support or policy changes may be
+required before an extension's capability is fully usable by userspace programs.
+Similarly, for S-mode extensions, presence in one of these lines does not
+guarantee that the kernel is taking advantage of the extension, or that the
+feature will be visible in guest VMs managed by this kernel.
+
+Inversely, the absence of an extension in these lines does not necessarily mean
+the hardware does not support that feature. The running kernel may not recognize
+the extension, or may have deliberately removed it from the listing.

Subject: [PATCH 1303/1451] RISC-V: Probe misaligned access speed in parallel

Probing for misaligned access speed takes about 0.06 seconds. On a
system with 64 cores, doing this in smp_callin() means it's done
serially, extending boot time by 3.8 seconds. That's a lot of boot time.

Instead of measuring each CPU serially, let's do the measurements on
all CPUs in parallel. If we disable preemption on all CPUs, the
jiffies stop ticking, so we can do this in stages of 1) everybody
except core 0, then 2) core 0. The allocations are all done outside of
on_each_cpu() to avoid calling alloc_pages() with interrupts disabled.

For hotplugged CPUs that come in after the boot time measurement,
register CPU hotplug callbacks, and do the measurement there. Interrupts
are enabled in those callbacks, so they're fine to do alloc_pages() in.

Subject: [PATCH 1304/1451] bpf: Let verifier consider {task,cgroup} is trusted
 in bpf_iter_reg

BTF_TYPE_SAFE_TRUSTED(struct bpf_iter__task) in verifier.c wanted to
teach BPF verifier that bpf_iter__task -> task is a trusted ptr. But it
doesn't work well.

The reason is, bpf_iter__task -> task would go through btf_ctx_access()
which enforces the reg_type of 'task' is ctx_arg_info->reg_type, and in
task_iter.c, we actually explicitly declare that the
ctx_arg_info->reg_type is PTR_TO_BTF_ID_OR_NULL.

Actually we have a previous case like this[1] where PTR_TRUSTED is added to
the arg flag for map_iter.

This patch sets ctx_arg_info->reg_type is PTR_TO_BTF_ID_OR_NULL |
PTR_TRUSTED in task_reg_info.

Similarly, bpf_cgroup_reg_info -> cgroup is also PTR_TRUSTED since we are
under the protection of cgroup_mutex and we would check cgroup_is_dead()
in __cgroup_iter_seq_show().

This patch is to improve the user experience of the newly introduced
bpf_iter_css_task kfunc before hitting the mainline. The Fixes tag is
pointing to the commit introduced the bpf_iter_css_task kfunc.

Subject: [PATCH 1305/1451] selftests/bpf: get trusted cgrp from
 bpf_iter__cgroup directly

Commit f49843afde (selftests/bpf: Add tests for css_task iter combining
with cgroup iter) added a test which demonstrates how css_task iter can be
combined with cgroup iter. That test used bpf_cgroup_from_id() to convert
bpf_iter__cgroup->cgroup to a trusted ptr which is pointless now, since
with the previous fix, we can get a trusted cgroup directly from
bpf_iter__cgroup.

Subject: [PATCH 1306/1451] ata: libata-core: Fix ata_pci_shutdown_one()

This reverts commit 5b6fba546da246b3d0dd8465c07783e22629cc53.

Commit 5b6fba546da2 ("ata: libata-core: Detach a port devices on
shutdown") modified the function ata_pci_shutdown_one() to stop
(suspend) devices attached to the ports of a PCI AHCI adapter to ensure
that drives are spun down before shutting down a system. However, this
is done only for PCI adapters and not for other types of adapters. This
limitation was addressed with commit 24eca2dce0f8 ("scsi: sd: Introduce
manage_shutdown device flag"). With this, all ATA disks are spun down on
system shutdown, which make the changes introduced with 5b6fba546da2
useless.

MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

On today's platforms the benefit of platform_driver_probe() isn't that
relevant any more. It allows to drop some code after booting (or module
loading) for .probe() and discard the .remove() function completely if
the driver is built-in. This typically saves a few 100k.

The downside of platform_driver_probe() is that the driver cannot be
bound and unbound at runtime which is ancient and so slightly
complicates testing. There are also thoughts to deprecate
platform_driver_probe() because it adds some complexity in the driver
core for little gain. Also many drivers don't use it correctly. This
driver for example misses to mark the driver struct with __ref which is
needed to suppress a (W=1) modpost warning.

The .remove() callback for a platform driver returns an int which makes
many driver authors wrongly assume it's possible to do error handling by
returning an error code. However the value returned is ignored (apart
from emitting a warning) and this typically results in resource leaks.

To improve here there is a quest to make the remove callback return
void. In the first step of this quest all drivers are converted to
.remove_new(), which already returns void. Eventually after all drivers
are converted, .remove_new() will be renamed to .remove().

Trivially convert this driver from always returning zero in the remove
callback to the void returning variant.

So far we ignore the setting of IFF_MULTICAST. Fix this and clear bit
AcceptMulticast if IFF_MULTICAST isn't set.

Note: Based on the implementations I've seen it doesn't seem to be 100% clear
what a driver is supposed to do if IFF_ALLMULTI is set but IFF_MULTICAST
is not. This patch is based on the understanding that IFF_MULTICAST has
precedence.

=====================================================

The following simple reproducer can cause the issue described above:

int main(void)
{
  int sock;
  struct sockaddr_vm addr = {
    .svm_family = AF_VSOCK,
    .svm_cid = VMADDR_CID_ANY,
    .svm_port = 1234,
  };

  sock = socket(AF_VSOCK, SOCK_STREAM, 0);
  connect(sock, (struct sockaddr *)&addr, sizeof(addr));
  return 0;
}

This issue occurs because the `buf_alloc` and `fwd_cnt` fields of the
`struct virtio_vsock_hdr` are not initialized when a new skb is allocated
in `virtio_transport_init_hdr()`. This patch resolves the issue by
initializing these fields during allocation.

 message to fit NETLINK_MAX_FMTMSG_LEN

NETLINK_MAX_FMTMSG_LEN is currently hardcoded to 80, and we provide an
error printf-formatted string having 96 characters including the
terminating \0. Assuming each %d (representing a queue) gets replaced by
a number having at most 2 digits (a reasonable assumption), the final
string is also 96 characters wide, which is too much.

Reduce the verbiage a bit by removing some (partially) redundant words,
which makes the new printf-formatted string be 73 characters wide with
the trailing newline.

The distance between vmlinux and the module is too far so that PC-REL
cannot be accessed directly, only GOT.

When compiling module with GCC, the option `-mdirect-extern-access` is
disabled by default. The Clang option `-fdirect-access-external-data` is
enabled by default, so it needs to be explicitly disabled.

  1 error generated.

If these functions are not inlined (which the compiler is free to do
even with functions marked with the standard 'inline' keyword), the
BUILD_BUG() in the default case cannot be eliminated since the compiler
cannot prove it is never used, resulting in a build failure due to the
error attribute.

Mark these functions as __always_inline to guarantee inlining so that
the BUILD_BUG() only triggers when the default case genuinely cannot be
eliminated due to an unexpected size.

Subject: [PATCH 1321/1451] LoongArch/smp: Call rcutree_report_cpu_starting()

rcutree_report_cpu_starting() must be called before cpu_probe() to avoid

raw_smp_processor_id() is required in order to avoid calling into lockdep
before RCU has declared the CPU to be watched for readers.

commit de5d9dae150c ("s390/smp: move rcu_cpu_starting() earlier") and commit

Add support for unconditional bswap instruction. Since LoongArch is
always little-endian, just treat unconditional bswap the same as big-
endian conversion.

MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Add support for 32-bit offset jmp instruction. Currently, we use b
instruction which supports range within ±128MB for such jumps. This
should be large enough for BPF progs.

Subject: [PATCH 1331/1451] i2c: iproc: handle invalid slave state

Add the code to handle an invalid state when both bits S_RX_EVENT
(indicating a transaction) and S_START_BUSY (indicating the end
of transaction - transition of START_BUSY from 1 to 0) are set in
the interrupt status register during a slave read.

Subject: [PATCH 1332/1451] i2c: designware: Disable TX_EMPTY irq while waiting
 for block length byte

During SMBus block data read process, we have seen high interrupt rate
because of TX_EMPTY irq status while waiting for block length byte (the
first data byte after the address phase). The interrupt handler does not
do anything because the internal state is kept as STATUS_WRITE_IN_PROGRESS.
Hence, we should disable TX_EMPTY IRQ until I2C DesignWare receives
first data byte from I2C device, then re-enable it to resume SMBus
transaction.

It takes 0.789 ms for host to receive data length from slave.
Without the patch, i2c_dw_isr() is called 99 times by TX_EMPTY interrupt.
And it is none after applying the patch.

Subject: [PATCH 1335/1451] drivers/net/ppp: use standard array-copy-function

In ppp_generic.c, memdup_user() is utilized to copy a userspace array.
This is done without an overflow-check, which is, however, not critical
because the multiplicands are an unsigned short and struct sock_filter,
which is currently of size 8.

Regardless, string.h now provides memdup_array_user(), a wrapper for
copying userspace arrays in a standardized manner, which has the
advantage of making it more obvious to the reader that an array is being
copied.
The wrapper additionally performs an obligatory overflow check, saving
the reader the effort of analyzing the potential for overflow, and
making the code a bit more robust in case of future changes to the
multiplicands len * size.

Replace memdup_user() with memdup_array_user().

From 93995bf4af2c5a99e2a87f0cd5ce547d31eb7630 Mon Sep 17 00:00:00 2001
From: Pablo Neira Ayuso <pablo@netfilter.org>
Date: Mon, 6 Nov 2023 10:53:09 +0100
Subject: [PATCH 1337/1451] netfilter: nf_tables: remove catchall element in GC
 sync path

The expired catchall element is not deactivated and removed from GC sync
path. This path holds mutex so just call nft_setelem_data_deactivate()
and nft_setelem_catchall_remove() before queueing the GC work.

Fixes: 4a9e12ea7e70 ("netfilter: nft_set_pipapo: call nft_trans_gc_queue_sync() in catchall GC")

Subject: [PATCH 1339/1451] netfilter: xt_recent: fix (increase) ipv6 literal
 buffer length
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

in6_pton() supports 'low-32-bit dot-decimal representation'
(this is useful with DNS64/NAT64 networks for example):

  # echo +aaaa:bbbb:cccc:dddd:eeee:ffff:1.2.3.4 > /proc/self/net/xt_recent/DEFAULT
  # cat /proc/self/net/xt_recent/DEFAULT
  src=aaaa:bbbb:cccc:dddd:eeee:ffff:0102:0304 ttl: 0 last_seen: 9733848829 oldest_pkt: 1 9733848829

but the provided buffer is too short:

  # echo +aaaa:bbbb:cccc:dddd:eeee:ffff:255.255.255.255 > /proc/self/net/xt_recent/DEFAULT
  -bash: echo: write error: Invalid argument

Subject: [PATCH 1341/1451] riscv: Don't use PGD entries for the linear mapping

Propagating changes at this level is cumbersome as we need to go through
all the page tables when that happens (either when changing the
permissions or when splitting the mapping).

Note that this prevents the use of 4MB mapping for sv32 and 1GB mapping for
sv39 in the linear mapping.

Subject: [PATCH 1342/1451] riscv: Fix set_memory_XX() and set_direct_map_XX()
 by splitting huge linear mappings

When STRICT_KERNEL_RWX is set, any change of permissions on any kernel
mapping (vmalloc/modules/kernel text...etc) should be applied on its
linear mapping alias. The problem is that the riscv kernel uses huge
mappings for the linear mapping and walk_page_range_novma() does not
split those huge mappings.

So this patchset implements such split in order to apply fine-grained
permissions on the linear mapping.

Below is the difference before and after (the first PUD mapping is split
into PTE/PMD mappings):

Note that this also fixes memfd_secret() syscall which uses
set_direct_map_invalid_noflush() and set_direct_map_default_noflush() to
remove the pages from the linear mapping. Below is the kernel page table
while a memfd_secret() syscall is running, you can see all the !valid

Subject: [PATCH 1343/1451] swiotlb: fix out-of-bounds TLB allocations with
 CONFIG_SWIOTLB_DYNAMIC

Limit the free list length to the size of the IO TLB. Transient pool can be
smaller than IO_TLB_SEGSIZE, but the free list is initialized with the
assumption that the total number of slots is a multiple of IO_TLB_SEGSIZE.
As a result, swiotlb_area_find_slots() may allocate slots past the end of
a transient IO TLB buffer.

From: Douglas Anderson <dianders@chromium.org>
Date: Tue, 7 Nov 2023 07:26:56 -0800
Subject: [PATCH 1344/1451] arm64: Move MediaTek GIC quirk handling from
 irqchip to core

In commit 44bd78dd2b88 ("irqchip/gic-v3: Disable pseudo NMIs on
MediaTek devices w/ firmware issues") we added a method for detecting
MediaTek devices with broken firmware and disabled pseudo-NMI. While
that worked, it didn't address the problem at a deep enough level.

The fundamental issue with this broken firmware is that it's not
saving and restoring several important GICR registers. The current
list is believed to be:
* GICR_NUM_IPRIORITYR
* GICR_CTLR
* GICR_ISPENDR0
* GICR_ISACTIVER0
* GICR_NSACR

Pseudo-NMI didn't work because it was the only thing (currently) in
the kernel that relied on the broken registers, so forcing pseudo-NMI
off was an effective fix. However, it could be observed that calling
system_uses_irq_prio_masking() on these systems still returned
"true". That caused confusion and led to the need for
commit a07a59415217 ("arm64: smp: avoid NMI IPIs with broken MediaTek
FW"). It's worried that the incorrect value returned by
system_uses_irq_prio_masking() on these systems will continue to
confuse future developers.

Let's fix the issue a little more completely by disabling IRQ
priorities at a deeper level in the kernel. Once we do this we can
revert some of the other bits of code dealing with this quirk.

This includes a partial revert of commit 44bd78dd2b88
("irqchip/gic-v3: Disable pseudo NMIs on MediaTek devices w/ firmware
issues"). This isn't a full revert because it leaves some of the
changes to the "quirks" structure around in case future code needs it.

Subject: [PATCH 1346/1451] netfilter: nat: fix ipv6 nat redirect with mapped
 and scoped addresses

The ipv6 redirect target was derived from the ipv4 one, i.e. its
identical to a 'dnat' with the first (primary) address assigned to the
network interface.  The code has been moved around to make it usable
from nf_tables too, but its still the same as it was back when this
was added in 2012.

IPv6, however, has different types of addresses, if the 'wrong' address
comes first the redirection does not work.

In Daniels case, the addresses are:
  inet6 ::ffff:192 ...
  inet6 2a01: ...

... so the function attempts to redirect to the mapped address.

Add more checks before the address is deemed correct:
1. If the packets' daddr is scoped, search for a scoped address too
2. skip tentative addresses
3. skip mapped addresses

Use the first address that appears to match our needs.

Subject: [PATCH 1347/1451] cifs: Fix encryption of cleared, but unset rq_iter
 data buffers

Each smb_rqst struct contains two things: an array of kvecs (rq_iov) that
contains the protocol data for an RPC op and an iterator (rq_iter) that
contains the data payload of an RPC op.  When an smb_rqst is allocated
rq_iter is it always cleared, but we don't set it up unless we're going to
use it.

The functions that determines the size of the ciphertext buffer that will
be needed to encrypt a request, cifs_get_num_sgs(), assumes that rq_iter is
always initialised - and employs user_backed_iter() to check that the
iterator isn't user-backed.  This used to incidentally work, because
->user_backed was set to false because the iterator has never been
initialised, but with commit f1b4cb650b9a0eeba206d8f069fcdc532bfbcd74[1]
which changes user_backed_iter() to determine this based on the iterator
type insted, a warning is now emitted:

        WARNING: CPU: 7 PID: 4584 at fs/smb/client/cifsglob.h:2165 smb2_get_aead_req+0x3fc/0x420 [cifs]

         do_new_mount+0x124/0x340
         __se_sys_mount+0x143/0x1a0

The problem is that rq_iter was never set, so the type is 0 (ie. ITER_UBUF)
which causes user_backed_iter() to return true.  The code doesn't
malfunction because it checks the size of the iterator - which is 0.

Fix cifs_get_num_sgs() to ignore rq_iter if its count is 0, thereby
bypassing the warnings.

It might be better to explicitly initialise rq_iter to a zero-length
ITER_BVEC, say, as it can always be reinitialised later.

Subject: [PATCH 1348/1451] nvme: keyring: fix conditional compilation

The keyring and auth functions can be called from both the host and
the target side and are controlled by Kconfig options for each of the
combinations, but the declarations are controlled by #ifdef checks
on the shared Kconfig symbols.

This leads to link failures in combinations where one of the frontends
is built-in and the other one is a module, and the keyring code
ends up in a module that is not reachable from the builtin code:

ld: drivers/nvme/host/core.o: in function `nvme_core_exit':
core.c:(.exit.text+0x4): undefined reference to `nvme_keyring_exit'
ld: drivers/nvme/host/core.o: in function `nvme_core_init':
core.c:(.init.text+0x94): undefined reference to `nvme_keyring_init

ld: drivers/nvme/host/tcp.o: in function `nvme_tcp_setup_ctrl':
tcp.c:(.text+0x4c18): undefined reference to `nvme_tls_psk_default'

Address this by moving nvme_keyring_init()/nvme_keyring_exit() into
module init/exit functions for the keyring module.

-EOPNOTSUPP is the return value that implements a "no-op" hook, not 0.

Without this fix having only the BPF LSM enabled (with no programs
attached) can cause uninitialized variable reads in
nfsd4_encode_fattr(), because the BPF hook returns 0 without touching
the 'ctxlen' variable and the corresponding 'contextlen' variable in
nfsd4_encode_fattr() remains uninitialized, yet being treated as valid
based on the 0 return value.

Subject: [PATCH 1351/1451] MAINTAINERS: update lists.linuxfoundation.org
 migrated lists

The mailman-2 system behind lists.linux[-]foundation.org is being
retired, so the lists are being migrated to lists.linux.dev.

Since both domains belong to LF and setting up proper forwards is
possible, the old addresses will continue to work for a while, but all
new patches should be sent to the new canonical addresses for each list.

Subject: [PATCH 1352/1451] net/sched: act_ct: Always fill offloading tuple
 iifidx

Referenced commit doesn't always set iifidx when offloading the flow to
hardware. Fix the following cases:

- nf_conn_act_ct_ext_fill() is called before extension is created with
nf_conn_act_ct_ext_add() in tcf_ct_act(). This can cause rule offload with
unspecified iifidx when connection is offloaded after only single
original-direction packet has been processed by tc data path. Always fill
the new nf_conn_act_ct_ext instance after creating it in
nf_conn_act_ct_ext_add().

- Offloading of unidirectional UDP NEW connections is now supported, but ct
flow iifidx field is not updated when connection is promoted to
bidirectional which can result reply-direction iifidx to be zero when
refreshing the connection. Fill in the extension and update flow iifidx
before calling flow_offload_refresh().

Subject: [PATCH 1356/1451] ptp: fix corrupted list in ptp_open

There is no lock protection when writing ptp->tsevqs in ptp_open() and
ptp_release(), which can cause data corruption, use spin lock to avoid this
issue.

Moreover, ptp_release() should not be used to release the queue in ptp_read(),
and it should be deleted altogether.

Subject: [PATCH 1357/1451] RISC-V: Don't fail in riscv_of_parent_hartid() for
 disabled HARTs

The riscv_of_processor_hartid() used by riscv_of_parent_hartid() fails
for HARTs disabled in the DT. This results in the following warning
thrown by the RISC-V INTC driver for the E-core on SiFive boards:

[    0.000000] riscv-intc: unable to find hart id for /cpus/cpu@0/interrupt-controller

The riscv_of_parent_hartid() is only expected to read the hartid
from the DT so we directly call of_get_cpu_hwid() instead of calling
riscv_of_processor_hartid().

That's because the fix in commit 3fec323339a4 ("drivers: perf: Fix panic
in riscv SBI mmap support") was wrong since there is no need to broadcast
to other cpus when starting a counter, that's only needed in mmap when
the counters could have already been started on other cpus, so simply
remove this broadcast.

Subject: [PATCH 1362/1451] ALSA: info: Fix potential deadlock at disconnection

As reported recently, ALSA core info helper may cause a deadlock at
the forced device disconnection during the procfs operation.

The proc_remove() (that is called from the snd_card_disconnect()
helper) has a synchronization of the pending procfs accesses via
wait_for_completion().  Meanwhile, ALSA procfs helper takes the global
mutex_lock(&info_mutex) at both the proc_open callback and
snd_card_info_disconnect() helper.  Since the proc_open can't finish
due to the mutex lock, wait_for_completion() never returns, either,
hence it deadlocks.

	TASK#1				TASK#2
	proc_reg_open()
	  takes use_pde()
	snd_info_text_entry_open()
					snd_card_disconnect()
					snd_info_card_disconnect()
					  takes mutex_lock(&info_mutex)
					proc_remove()
					wait_for_completion(unused_pde)
					  ... waiting task#1 closes
	mutex_lock(&info_mutex)
		=> DEADLOCK

This patch is a workaround for avoiding the deadlock scenario above.

The basic strategy is to move proc_remove() call outside the mutex
lock.  proc_remove() can work gracefully without extra locking, and it
can delete the tree recursively alone.  So, we call proc_remove() at
snd_info_card_disconnection() at first, then delete the rest resources
recursively within the info_mutex lock.

After the change, the function snd_info_disconnect() doesn't do
disconnection by itself any longer, but it merely clears the procfs
pointer.  So rename the function to snd_info_clear_entries() for
avoiding confusion.

The similar change is applied to snd_info_free_entry(), too.  Since
the proc_remove() is called only conditionally with the non-NULL
entry->p, it's skipped after the snd_info_clear_entries() call.

Subject: [PATCH 1363/1451] ALSA: hda: ASUS UM5302LA: Added quirks for
 cs35L41/10431A83 on i2c bus

Proposed patch fixes initialization of CSC3551 on the UM5302LA laptop.
Patching DSDT table is not required since ASUS did added _DSD entry.
Nothing new introduced but reused work started by Stefan B.

Currently there is no official firmware available for 10431A83 on
cirrus git unfortunately.
For testing used 104317f3 (which is also seems on i2c bus):

$ cd /lib/firmware/cirrus/ && \
for fw in $(find ./ -name '*104317f3*'); do newfw=$(echo $fw | sed 's/104317f3/10431a83/g'); echo echo "$fw -> $newfw"; ln -s $f $newfw; done

With the patch applied to 6.6.0 and obviously symlinks to 104317F3 FW,
speakers works and to my susrprise they sound quite good and loud
without distortion.

Probably confirmation from cirrus team is needed on firmware.

Subject: [PATCH 1366/1451] cifs: handle cases where a channel is closed

So far, SMB multichannel could only scale up, but not
scale down the number of channels. In this series of
patch, we now allow the client to deal with the case
of multichannel disabled on the server when the share
is mounted. With that change, we now need the ability
to scale down the channels.

This change allows the client to deal with cases of
missing channels more gracefully.

Subject: [PATCH 1367/1451] cifs: distribute channels across interfaces based
 on speed

Today, if the server interfaces RSS capable, we simply
choose the fastest interface to setup a channel. This is not
a scalable approach, and does not make a lot of attempt to
distribute the connections.

This change does a weighted distribution of channels across
all the available server interfaces, where the weight is
a function of the advertised interface speed.

Also make sure that we don't mix rdma and non-rdma for channels.

Subject: [PATCH 1368/1451] cifs: account for primary channel in the interface
 list

The refcounting of server interfaces should account
for the primary channel too. Although this is not
strictly necessary, doing so will account for the primary
channel in DebugData.

Subject: [PATCH 1369/1451] cifs: do not pass cifs_sb when trying to add
 channels

The only reason why cifs_sb gets passed today to cifs_try_adding_channels
is to pass the local_nls field for the new channels and binding session.
However, the ses struct already has local_nls field that is setup during
the first cifs_setup_session. So there is no need to pass cifs_sb.

This change removes cifs_sb from the arg list for this and the functions
that it calls and uses ses->local_nls instead.

Subject: [PATCH 1370/1451] cifs: reconnect work should have reference on
 server struct

The delayed work for reconnect takes server struct
as a parameter. But it does so without holding a ref
to it. Normally, this may not show a problem as
the reconnect work is only cancelled on umount.

However, since we now plan to support scaling down of
channels, and the scale down can happen from reconnect
work itself, we need to fix it.

This change takes a reference on the server struct
before it is passed to the delayed work. And drops
the reference in the delayed work itself. Or if
the delayed work is successfully cancelled, by the
process that cancels it.

 callback returning void
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The .remove() callback for a platform driver returns an int which makes
many driver authors wrongly assume it's possible to do error handling by
returning an error code. However the value returned is ignored (apart
from emitting a warning) and this typically results in resource leaks.

To improve here there is a quest to make the remove callback return
void. In the first step of this quest all drivers are converted to
.remove_new(), which already returns void. Eventually after all drivers
are converted, .remove_new() will be renamed to .remove().

Trivially convert this driver from always returning zero in the remove
callback to the void returning variant.

Commit 6ac19f96515e ("arm64: avoid prototype warnings for syscalls")
added missing declarations to various syscall wrapper macros. It
however proved a little too zealous in __SYSCALL_DEFINEx(), as a
declaration for __arm64_sys##name was already present. A declaration
is required before the call to ALLOW_ERROR_INJECTION(), so keep
the original one and remove the new one.

Subject: [PATCH 1375/1451] riscv: Rearrange hwcap.h and cpufeature.h

Now hwcap.h and cpufeature.h are mutually including each other, and most of
the variable/API declarations in hwcap.h are implemented in cpufeature.c,
so, it's better to move them into cpufeature.h and leave only macros for
ISA extension logical IDs in hwcap.h.

BTW, the riscv_isa_extension_mask macro is not used now, so this patch
removes it.

Subject: [PATCH 1376/1451] riscv: Optimize bitops with Zbb extension

This patch leverages the alternative mechanism to dynamically optimize
bitops (including __ffs, __fls, ffs, fls) with Zbb instructions. When
Zbb ext is not supported by the runtime CPU, legacy implementation is
used. If Zbb is supported, then the optimized variants will be selected
via alternative patching.

The legacy bitops support is taken from the generic C implementation as
fallback.

If the parameter is a build-time constant, we leverage compiler builtin to
calculate the result directly, this approach is inspired by x86 bitops
implementation.

EFI stub runs before the kernel, so alternative mechanism should not be
used there, this patch introduces a macro NO_ALTERNATIVE for this purpose.

Subject: [PATCH 1377/1451] smb: client: fix mount when dns_resolver key is not
 available

There was a wrong assumption that with CONFIG_CIFS_DFS_UPCALL=y there
would always be a dns_resolver key set up so we could unconditionally
upcall to resolve UNC hostname rather than using the value provided by
mount(2).

Only require it when performing automount of junctions within a DFS
share so users that don't have dns_resolver key still can mount their
regular shares with server hostname resolved by mount.cifs(8).

We should not leak the pointer where we couldn't grab the reference
on to the caller because it can be that the error handling still
tries to put the reference then.

Subject: [PATCH 1386/1451] drm/amdgpu: Add xcc param to SRIOV kiq write and
 WREG32_SOC15_IP_NO_KIQ (v4)

WREG32/RREG32_SOC15_IP_NO_KIQ and amdgpu_virt_kiq_reg_write_reg_wait
are not using the correct rlcg interface or mec engine, respectively.

Add xcc instance parameter to them.

v4: Use GET_INST and squash commit with:
"drm/amdgpu: Add xcc_inst param to amdgpu_virt_kiq_reg_write_reg_wait"

v3: xcc not needed for MMMHUB

v2: rebase

Spotted by coccicheck, there is a redundant check for
v->SourcePixelFormat[k] != dm_444_16. This patch will
remove it. The corresponding output follows.

Subject: [PATCH 1401/1451] drm/amdgpu: Use correct KIQ MEC engine for gfx9.4.3
 (v5)

amdgpu_kiq_wreg/rreg is hardcoded to use MEC engine 0.

Add an xcc_id parameter to amdgpu_kiq_wreg/rreg, define W/RREG32_XCC
and amdgpu_device_xcc_wreg/rreg to use the new xcc_id parameter.

Using amdgpu_sriov_runtime to determine whether to access via kiq or
RLC is sufficient for now.

v5: add condition in amdgpu_device_xcc_w/rreg, remove trace func call

v4: avoid using amdgpu_sriov_w/rreg

v3: use W/RREG32_XCC to handle non-kiq case

v2: define amdgpu_device_xcc_wreg/rreg instead of changing parameters
    of amdgpu_device_wreg/rreg

From 197264284303b30b26e885d83680f594e69840e5 Mon Sep 17 00:00:00 2001
From: Victor Lu <victorchengchi.lu@amd.com>
Date: Tue, 8 Aug 2023 14:28:56 -0400
Subject: [PATCH 1402/1451] drm/amdgpu: Change WREG32_RLC to WREG32_SOC15_RLC
 where inst != 0 (v2)

W/RREG32_RLC is hardedcoded to use instance 0. W/RREG32_SOC15_RLC
should be used instead when inst != 0.

v2: rebase

Subject: [PATCH 1403/1451] fbdev: atmel_lcdfb: Stop using
 platform_driver_probe()
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

On today's platforms the benefit of platform_driver_probe() isn't that
relevant any more. It allows to drop some code after booting (or module
loading) for .probe() and discard the .remove() function completely if
the driver is built-in. This typically saves a few 100k.

The downside of platform_driver_probe() is that the driver cannot be
bound and unbound at runtime which is ancient and also slightly
complicates testing. There are also thoughts to deprecate
platform_driver_probe() because it adds some complexity in the driver
core for little gain. Also many drivers don't use it correctly. This
driver for example misses to mark the driver struct with __refdata which
is needed to suppress a (W=1) modpost warning:

	WARNING: modpost: drivers/video/fbdev/atmel_lcdfb: section mismatch in reference: atmel_lcdfb_driver+0x4 (section: .data) -> atmel_lcdfb_remove (section: .exit.text)

Subject: [PATCH 1408/1451] fbdev: omapfb/hdmi: Don't put .remove() in
 .exit.text and drop suppress_bind_attrs
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

On today's platforms the memory savings of putting the remove function
in .exit isn't that relevant any more. It only matters for built-in
drivers and typically saves a few 100k.

The downside is that the driver cannot be unbound at runtime which is
ancient and also slightly complicates testing. Also it requires to mark
the driver struct with __refdata which is needed to suppress a (W=1)
modpost warning:

	WARNING: modpost: drivers/video/fbdev/omap2/omapfb/displays/connector-hdmi: section mismatch in reference: hdmi_connector_driver+0x4 (section: .data) -> hdmic_remove (section: .exit.text)

To simplify matters, move the remove callback to .text and drop
.suppress_bind_attrs = true.

The .remove() callback for a platform driver returns an int which makes
many driver authors wrongly assume it's possible to do error handling by
returning an error code. However the value returned is ignored (apart
from emitting a warning) and this typically results in resource leaks.

To improve here there is a quest to make the remove callback return
void. In the first step of this quest all drivers are converted to
.remove_new(), which already returns void. Eventually after all drivers
are converted, .remove_new() will be renamed to .remove().

Trivially convert this driver from always returning zero in the remove
callback to the void returning variant.

Subject: [PATCH 1416/1451] fbdev: omapfb/dsi-cm: Convert to platform remove
 callback returning void
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The .remove() callback for a platform driver returns an int which makes
many driver authors wrongly assume it's possible to do error handling by
returning an error code. However the value returned is ignored (apart
from emitting a warning) and this typically results in resource leaks.

To improve here there is a quest to make the remove callback return
void. In the first step of this quest all drivers are converted to
.remove_new(), which already returns void. Eventually after all drivers
are converted, .remove_new() will be renamed to .remove().

Trivially convert this driver from always returning zero in the remove
callback to the void returning variant.

Subject: [PATCH 1423/1451] fbdev: hyperv_fb: fix uninitialized local variable
 use

When CONFIG_SYSFB is disabled, the hyperv_fb driver can now run into
undefined behavior on a gen2 VM, as indicated by this smatch warning:

drivers/video/fbdev/hyperv_fb.c:1077 hvfb_getmem() error: uninitialized symbol 'base'.
drivers/video/fbdev/hyperv_fb.c:1077 hvfb_getmem() error: uninitialized symbol 'size'.

Since there is no way to know the actual framebuffer in this configuration,
just return an allocation failure here, which should avoid the build
warning and the undefined behavior.

Reported-by: kernel test robot <lkp@intel.com>
Reported-by: Dan Carpenter <dan.carpenter@linaro.org>
Closes: https://lore.kernel.org/r/202311070802.YCpvehaz-lkp@intel.com/

Subject: [PATCH 1425/1451] smb3: allow dumping session and tcon id to improve
 stats analysis and debugging

When multiple mounts are to the same share from the same client it was not
possible to determine which section of /proc/fs/cifs/Stats (and DebugData)
correspond to that mount.  In some recent examples this turned out to  be
a significant problem when trying to analyze performance data - since
there are many cases where unless we know the tree id and session id we
can't figure out which stats (e.g. number of SMB3.1.1 requests by type,
the total time they take, which is slowest, how many fail etc.) apply to
which mount. The only existing loosely related ioctl CIFS_IOC_GET_MNT_INFO
does not return the information needed to uniquely identify which tcon
is which mount although it does return various flags and device info.

Add a cifs.ko ioctl CIFS_IOC_GET_TCON_INFO (0x800ccf0c) to return tid,
session id, tree connect count.

Subject: [PATCH 1427/1451] fbdev: amifb: Convert to platform remove callback
 returning void
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The .remove() callback for a platform driver returns an int which makes
many driver authors wrongly assume it's possible to do error handling by
returning an error code. However the value returned is ignored (apart
from emitting a warning) and this typically results in resource leaks.

To improve here there is a quest to make the remove callback return
void. In the first step of this quest all drivers are converted to
.remove_new(), which already returns void. Eventually after all drivers
are converted, .remove_new() will be renamed to .remove().

Trivially convert this driver from always returning zero in the remove
callback to the void returning variant.

These enums are passed to set/test_bit().  The set/test_bit() functions
take a bit number instead of a shifted value.  Passing a shifted value
is a double shift bug like doing BIT(BIT(1)).  The double shift bug
doesn't cause a problem here because we are only checking 0 and 1 but
if the value was 5 or above then it can lead to a buffer overflow.

Most architectures that support kprobes declare this function in their
own asm/kprobes.h header and provide an override, but some are missing
the prototype, which causes a warning for the __weak stub implementation:

Move the prototype into linux/kprobes.h so it is visible to all
the definitions.

Subject: [PATCH 1434/1451] tracing: fprobe-event: Fix to check tracepoint
 event and return

Fix to check the tracepoint event is not valid with $retval.
The commit 08c9306fc2e3 ("tracing/fprobe-event: Assume fprobe is
a return event by $retval") introduced automatic return probe
conversion with $retval. But since tracepoint event does not
support return probe, $retval is not acceptable.

Without this fix, ftracetest, tprobe_syntax_errors.tc fails;

[22] Tracepoint probe event parser error log check      [FAIL]
 ----
 # tail 22-tprobe_syntax_errors.tc-log.mRKroL
 + ftrace_errlog_check trace_fprobe t kfree ^$retval dynamic_events
 + printf %s t kfree
 + wc -c
 + pos=8
 + printf %s t kfree ^$retval
 + tr -d ^
 + command=t kfree $retval
 + echo Test command: t kfree $retval
 Test command: t kfree $retval
 + echo
 ----

So 't kfree $retval' should fail (tracepoint doesn't support
return probe) but passed it.

Subject: [PATCH 1435/1451] spi: Fix null dereference on suspend

A race condition exists where a synchronous (noqueue) transfer can be
active during a system suspend. This can cause a null pointer
dereference exception to occur when the system resumes.

Example order of events leading to the exception:
1. spi_sync() calls __spi_transfer_message_noqueue() which sets
   ctlr->cur_msg
2. Spi transfer begins via spi_transfer_one_message()
3. System is suspended interrupting the transfer context
4. System is resumed
6. spi_controller_resume() calls spi_start_queue() which resets cur_msg
   to NULL
7. Spi transfer context resumes and spi_finalize_current_message() is
   called which dereferences cur_msg (which is now NULL)

Wait for synchronous transfers to complete before suspending by
acquiring the bus mutex and setting/checking a suspend flag.

If a user has disabled GFXOFF this may cause problems for the suspend
sequence.  Ensure that it is enabled in amdgpu_acpi_is_s0ix_active().

The system won't reach the deepest state but it also won't hang.

Subject: [PATCH 1442/1451] drm/amdgpu: move kfd_resume before the ip late init

The kfd_resume needs to touch GC registers to enable the interrupts,
it needs to be done before GFXOFF is enabled to ensure that the GFX is
not off and GC registers can be touched. So move kfd_resume before the
amdgpu_device_ip_late_init which enables the CGPG/GFXOFF.

 after sched init
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

We need kernel scheduling entities to deal with handle clean up
if apps are not cleaned up properly.  With commit 56e449603f0ac5
("drm/sched: Convert the GPU scheduler to variable number of run-queues")
the scheduler entities have to be created after scheduler init, so
change the ordering to fix this.

v2: Leave logic in UVD and VCE code

 switch

We should send uevent to userspace whenever the link speed or width
changes but tb_switch_asym_enable() and tb_switch_asym_disable() set the
sw->link_width already so tb_switch_update_link_attributes() never
noticed the change.

Fix this so that we let tb_switch_update_link_attributes() update the
fields accordingly.

Subject: [PATCH 1451/1451] thunderbolt: Only add device router DP IN to the
 head of the DP resource list

When pairing DP IN and DP OUT adapters for DisplayPort tunneling, we
should prioritize the possible external GPU DP IN adapters to take
advantage of the its capabilities. However the commit in question did
this for host router DP IN adapters too and that changes ordering of the
initial DP IN resources in such way that resuming from suspend may end
up using different resource and that may confuse the user.

Fix this so that we only put DP IN adapters of device routers to the top
of the resource list and leave host routers as is.
