In a future change, the driver will need to determine whether PTP RX
timestamping is enabled on a port (including whether traps were set up
on that port in particular) and that is currently not possible.

The driver supports different RX filters (L2, L4) and kinds of TX
timestamping (one-step, two-step) on its ports, but it saves all
configuration in a single struct hwtstamp_config that is global to the
switch. So, the latest timestamping configuration on one port
(including a request to disable timestamping) affects what gets reported
for all ports, even though the configuration itself is still individual
to each port.

The port timestamping configurations are only coupled because of the
common structure, so replace the hwtstamp_config with a mask of trapped
protocols saved per port. We also have the ptp_cmd to distinguish
between one-step and two-step PTP timestamping, so with those 2 bits of
information we can fully reconstruct a descriptive struct
hwtstamp_config for each port, during the SIOCGHWTSTAMP ioctl.

PTP RX timestamping should be enabled when the user requests it, not by
default. If it is enabled by default, it can be problematic when the
ocelot driver is a DSA master, and it sidesteps what DSA tries to avoid
through __dsa_master_hwtstamp_validate().

Additionally, after the change which made ocelot trap PTP packets only
to the CPU at ocelot_hwtstamp_set() time, it is no longer even true that
RX timestamping is enabled by default, because until ocelot_hwtstamp_set()
is called, the PTP traps are actually not set up. So the rx_filter field
of ocelot->hwtstamp_config reflects an incorrect reality.

====================
net/sched: act_ipt bug fixes

v3: prefer skb_header() helper in patch 2.  No other changes.
I've retained Acks and RvB-Tags of v2.

While checking if netfilter could be updated to replace selected
instances of NF_DROP with kfree_skb_reason+NF_STOLEN to improve
debugging info via drop monitor I found that act_ipt is incompatible
with such an approach.  Moreover, it lacks multiple sanity checks
to avoid certain code paths that make assumptions that the tc layer
doesn't meet, such as header sanity checks, availability of skb_dst,
skb_nfct() and so on.

act_ipt test in the tc selftest still pass with this applied.

I think that we should consider removal of this module, while
this should take care of all problems, its ipv4 only and I don't
think there are any netfilter targets that lack a native tc
equivalent, even when ignoring bpf.

xtables relies on skb being owned by ip stack, i.e. with ipv4
check in place skb->cb is supposed to be IPCB.

I don't see an immediate problem (REJECT target cannot be used anymore
now that PRE/POSTROUTING hook validation has been fixed), but better be
safe than sorry.

A much better patch would be to either mark act_ipt as
"depends on BROKEN" or remove it altogether. I plan to do this
for -next in the near future.

This tc extension is broken in the sense that tc lacks an
equivalent of NF_STOLEN verdict.

With NF_STOLEN, target function takes complete ownership of skb, caller
cannot dereference it anymore.

ACT_STOLEN cannot be used for this: it has a different meaning, caller
is allowed to dereference the skb.

At this time NF_STOLEN won't be returned by any targets as far as I can
see, but this may change in the future.

It might be possible to work around this via list of allowed
target extensions known to only return DROP or ACCEPT verdicts, but this
is error prone/fragile.

Existing selftest only validates xt_LOG and act_ipt is restricted
to ipv4 so I don't think this action is used widely.

Netfilter targets make assumptions on the skb state, for example
iphdr is supposed to be in the linear area.

This is normally done by IP stack, but in act_ipt case no
such checks are made.

Some targets can even assume that skb_dst will be valid.
Make a minimum effort to check for this:

- Don't call the targets eval function for non-ipv4 skbs.
- Don't call the targets eval function for POSTROUTING
  emulation when the skb has no dst set.

Looks like "tc" hard-codes "mangle" as the only supported table
name, but on kernel side there are no checks.

This is wrong.  Not all xtables targets are safe to call from tc.
E.g. "nat" targets assume skb has a conntrack object assigned to it.
Normally those get called from netfilter nat core which consults the
nat table to obtain the address mapping.

"tc" userspace either sets PRE or POSTROUTING as hook number, but there
is no validation of this on kernel side, so update netlink policy to
reject bogus numbers.  Some targets may assume skb_dst is set for
input/forward hooks, so prevent those from being used.

act_ipt uses the hook number in two places:
1. the state hook number, this is fine as-is
2. to set par.hook_mask

The latter is a bit mask, so update the assignment to make
xt_check_target() to the right thing.

Followup patch adds required checks for the skb/packet headers before
calling the targets evaluation function.

As &net->sctp.addr_wq_lock is also acquired by the timer
sctp_addr_wq_timeout_handler() in protocal.c, the same lock acquisition
at sctp_auto_asconf_init() seems should disable irq since it is called
from sctp_accept() under process context.

Possible deadlock scenario:
sctp_accept()
    -> sctp_sock_migrate()

Pull networking changes from Jakub Kicinski:
 "WiFi 7 and sendpage changes are the biggest pieces of work for this
  release. The latter will definitely require fixes but I think that we
  got it to a reasonable point.

  Core:

   - Rework the sendpage & splice implementations

     Instead of feeding data into sockets page by page extend sendmsg
     handlers to support taking a reference on the data, controlled by a
     new flag called MSG_SPLICE_PAGES

     Rework the handling of unexpected-end-of-file to invoke an
     additional callback instead of trying to predict what the right
     combination of MORE/NOTLAST flags is

     Remove the MSG_SENDPAGE_NOTLAST flag completely

   - Implement SCM_PIDFD, a new type of CMSG type analogous to
     SCM_CREDENTIALS, but it contains pidfd instead of plain pid

   - Enable socket busy polling with CONFIG_RT

   - Improve reliability and efficiency of reporting for ref_tracker

   - Auto-generate a user space C library for various Netlink families

  Protocols:

   - Allow TCP to shrink the advertised window when necessary, prevent
     sk_rcvbuf auto-tuning from growing the window all the way up to
     tcp_rmem[2]

   - Use per-VMA locking for "page-flipping" TCP receive zerocopy

   - Prepare TCP for device-to-device data transfers, by making sure
     that payloads are always attached to skbs as page frags

   - Make the backoff time for the first N TCP SYN retransmissions
     linear. Exponential backoff is unnecessarily conservative

   - Create a new MPTCP getsockopt to retrieve all info
     (MPTCP_FULL_INFO)

   - Avoid waking up applications using TLS sockets until we have a full
     record

   - Allow using kernel memory for protocol ioctl callbacks, paving the
     way to issuing ioctls over io_uring

   - Add nolocalbypass option to VxLAN, forcing packets to be fully
     encapsulated even if they are destined for a local IP address

   - Make TCPv4 use consistent hash in TIME_WAIT and SYN_RECV. Ensure
     in-kernel ECMP implementation (e.g. Open vSwitch) select the same
     link for all packets. Support L4 symmetric hashing in Open vSwitch

   - PPPoE: make number of hash bits configurable

   - Allow DNS to be overwritten by DHCPACK in the in-kernel DHCP client
     (ipconfig)

   - Add layer 2 miss indication and filtering, allowing higher layers
     (e.g. ACL filters) to make forwarding decisions based on whether
     packet matched forwarding state in lower devices (bridge)

   - Support matching on Connectivity Fault Management (CFM) packets

   - Hide the "link becomes ready" IPv6 messages by demoting their
     printk level to debug

   - HSR: don't enable promiscuous mode if device offloads the proto

   - Support active scanning in IEEE 802.15.4

   - Continue work on Multi-Link Operation for WiFi 7

  BPF:

   - Add precision propagation for subprogs and callbacks. This allows
     maintaining verification efficiency when subprograms are used, or
     in fact passing the verifier at all for complex programs,
     especially those using open-coded iterators

   - Improve BPF's {g,s}setsockopt() length handling. Previously BPF
     assumed the length is always equal to the amount of written data.
     But some protos allow passing a NULL buffer to discover what the
     output buffer *should* be, without writing anything

   - Accept dynptr memory as memory arguments passed to helpers

   - Add routing table ID to bpf_fib_lookup BPF helper

   - Support O_PATH FDs in BPF_OBJ_PIN and BPF_OBJ_GET commands

   - Drop bpf_capable() check in BPF_MAP_FREEZE command (used to mark
     maps as read-only)

   - Show target_{obj,btf}_id in tracing link fdinfo

   - Addition of several new kfuncs (most of the names are
     self-explanatory):
      - Add a set of new dynptr kfuncs: bpf_dynptr_adjust(),
        bpf_dynptr_is_null(), bpf_dynptr_is_rdonly(), bpf_dynptr_size()
        and bpf_dynptr_clone().
      - bpf_task_under_cgroup()
      - bpf_sock_destroy() - force closing sockets
      - bpf_cpumask_first_and(), rework bpf_cpumask_any*() kfuncs

  Netfilter:

   - Relax set/map validation checks in nf_tables. Allow checking
     presence of an entry in a map without using the value

   - Increase ip_vs_conn_tab_bits range for 64BIT builds

   - Allow updating size of a set

   - Improve NAT tuple selection when connection is closing

  Driver API:

   - Integrate netdev with LED subsystem, to allow configuring HW
     "offloaded" blinking of LEDs based on link state and activity
     (i.e. packets coming in and out)

   - Support configuring rate selection pins of SFP modules

   - Factor Clause 73 auto-negotiation code out of the drivers, provide
     common helper routines

   - Add more fool-proof helpers for managing lifetime of MDIO devices
     associated with the PCS layer

   - Allow drivers to report advanced statistics related to Time Aware
     scheduler offload (taprio)

   - Allow opting out of VF statistics in link dump, to allow more VFs
     to fit into the message

   - Split devlink instance and devlink port operations

  The most difficult user to modify was parport which required a bit of

  bytes according to bloat-o-meter. Since we gained a few bloat-o-meter
  karma points I moved two rather small sysctl arrays from
  kernel/sysctl.c leaving us only two more sysctl arrays to move left.

  last straggler patches are a minor parport fix, changes to the sysctl
  kernel selftest so to verify correctness and prevent regressions for
  the future change he made to provide an alternative solution for the
  special sysctl mount point target which was using the now deprecated
  sysctl child element.

  This is all prep work to now finally be able to remove the empty array
  element in all sysctl declarations / registrations which is expected
  to save us a bit of bytes all over the kernel. That work will be

This is the new-and-improved attempt at avoiding huge memory load spikes
when the user space boot sequence tries to load hundreds (or even
thousands) of redundant duplicate modules in parallel.

See commit 9828ed3f ("module: error out early on concurrent load of
the same module file") for background and an earlier failed attempt that
was reverted.

That earlier attempt just said "concurrently loading the same module is
silly, just open the module file exclusively and return -ETXTBSY if
somebody else is already loading it".

While it is true that concurrent module loads of the same module is
silly, the reason that earlier attempt then failed was that the
concurrently loaded module would often be a prerequisite for another
module.

Thus failing to load the prerequisite would then cause cascading
failures of the other modules, rather than just short-circuiting that
one unnecessary module load.

At the same time, we still really don't want to load the contents of the
same module file hundreds of times, only to then wait for an eventually
successful load, and have everybody else return -EEXIST.

As a result, this takes another approach, and treats concurrent module
loads from the same file as "idempotent" in the inode.  So if one module
load is ongoing, we don't start a new one, but instead just wait for the
first one to complete and return the same return value as it did.

So unlike the first attempt, this does not return early: the intent is
not to speed up the boot, but to avoid a thundering herd problem in
allocating memory (both physical and virtual) for a module more than
once.

Also note that this does change behavior: it used to be that when you
had concurrent loads, you'd have one "winner" that would return success,
and everybody else would return -EEXIST.

In contrast, this idempotent logic goes all Oprah on the problem, and
says "You are a winner! And you are a winner! We are ALL winners".  But
since there's no possible actual real semantic difference between "you
loaded the module" and "somebody else already loaded the module", this
is more of a feel-good change than an actual honest-to-goodness semantic
change.

Of course, any true Johnny-come-latelies that don't get caught in the
concurrency filter will still return -EEXIST.  It's no different from
not even getting a seat at an Oprah taping.  That's life.

See the long thread on the kernel mailing list about this all, which
includes some numbers for memory use before and after the patch.

Pull regmap updates from Mark Brown:
 "Another busy release for regmap with the second half of the maple tree
  register cache implementation, there's some smaller optimisations that
  could be done but this should now be able to replace the rbtree cache
  for most devices.

  We also had a followup from Aidan MacDonald's refactoring of some of
  the regmap-irq interfaces, the conversion is complete so the old
  interfaces are removed. This means that even with the new features for
  the maple tree cache we'd have a nice negative diffstat were it not
  for the addition of a bunch more KUnit coverage.

  There's one GPIO patch in here, it was a dependency for a cleanup of
  an API in the regmap-irq code for which the gpio-104-dio-48e driver
  was the only user.

  Highlights:

   - The maple tree cache can now load in default values more
     efficiently, and is capabale of syncing multiple registers
     in a single write during cache sync

   - More KUnit coverage, including some coverage for raw I/O
     and a dummy RAM backed cache to support it

   - Removal of several old interfaces in regmap-irq now all
     users have been modernised"

The memory encryption initialization logic was moved from init/main.c
into arch_cpu_finalize_init() in commit 439e1757 ("init, x86: Move
mem_encrypt_init() into arch_cpu_finalize_init()"), but a stale
declaration for the init function was left in <linux/init.h>.

And didn't cause any problems if you had X86_MEM_ENCRYPT enabled, which
apparently everybody involved did have.  See also commit 0a9567ac
("x86/mem_encrypt: Unbreak the AMD_MEM_ENCRYPT=n build") in this whole
sad saga of conflicting declarations for different situations.

Commit ca5e8632 ("mm/gup: remove vmas parameter from
get_user_pages_remote()") removed the vma argument from GUP handling,
and instead added a helper function (get_user_page_vma_remote()) that
looks it up separately using 'vma_lookup()'.  And then converted
existing users that needed a vma to use the helper instead.

However, the helper function intentionally acts exactly like the old
get_user_pages_remote() did, and only fills in 'vma' on successful page
lookup.  Fine so far.

However, __access_remote_vm() wants the vma even for the unsuccessful
case, and used to do a

	vma = vma_lookup(mm, addr);

explicitly to look it up when the get_user_page() failed.

However, that conversion commit incorrectly removed that vma lookup,
thinking that get_user_page_vma_remote() would have done it.  Not so.

So add the vma_lookup() back in.

Pull hardening updates from Kees Cook:
 "There are three areas of note:

  A bunch of strlcpy()->strscpy() conversions ended up living in my tree
  since they were either Acked by maintainers for me to carry, or got
  ignored for multiple weeks (and were trivial changes).

  The compiler option '-fstrict-flex-arrays=3' has been enabled
  globally, and has been in -next for the entire devel cycle. This
  changes compiler diagnostics (though mainly just -Warray-bounds which
  is disabled) and potential UBSAN_BOUNDS and FORTIFY _warning_
  coverage. In other words, there are no new restrictions, just
  potentially new warnings. Any new FORTIFY warnings we've seen have
  been fixed (usually in their respective subsystem trees). For more
  details, see commit df8fc4e9.

  The under-development compiler attribute __counted_by has been added
  so that we can start annotating flexible array members with their
  associated structure member that tracks the count of flexible array
  elements at run-time. It is possible (likely?) that the exact syntax
  of the attribute will change before it is finalized, but GCC and Clang
  are working together to sort it out. Any changes can be made to the
  macro while we continue to add annotations.

  As an example of that last case, I have a treewide commit waiting with
  such annotations found via Coccinelle:

    https://git.kernel.org/linus/adc5b3cb48a049563dc673f348eab7b6beba8a9b

   - Flexible array conversions (Arnd Bergmann, Wyes Karny, Kees Cook)

 - A SafeSetID patch to correct what appears to be a cut-n-paste typo in

   This is coming via the LSM tree because we haven't been able to get a
   response from the SafeSetID maintainer (Micah Morton) in several
   months. Hopefully we are able to get in touch with Micah, but until
   we do I'm going to pick them up in the LSM tree.

 - A small fix to the reiserfs LSM xattr code.

   We're continuing to work through some issues with the reiserfs code
   as we try to fixup the LSM xattr handling, but in the process we're
   uncovering some ugly problems in reiserfs and we may just end up
   removing the LSM xattr support in reiserfs prior to reiserfs'
   removal.

   For better or worse, this shouldn't impact any of the reiserfs users,
   as we discovered that LSM xattrs on reiserfs were completely broken,
   meaning no one is currently using the combo of reiserfs and a file
   labeling LSM.

 - A tweak to how the cap_user_data_t struct/typedef is declared in the
   header file to appease the Sparse gods.

 - In the process of trying to sort out the SafeSetID lost-maintainer
   problem I realized that I needed to update the labeled networking
   entry to "Supported".

Pull selinux updates from Paul Moore:

 - Thanks to help from the MPTCP folks, it looks like we have finally
   sorted out a proper solution to the MPTCP socket labeling issue, see
   the new security_mptcp_add_subflow() LSM hook.

 - Fix the labeled NFS handling such that a labeled NFS share mounted
   prior to the initial SELinux policy load is properly labeled once a
   policy is loaded; more information in the commit description.

 - Two patches to security/selinux/Makefile, the first took the cleanups
   in v6.4 a bit further and the second removed the grouped targets
   support as that functionality doesn't appear to be properly supported
   prior to make v4.3.

 - Deprecate the "fs" object context type in SELinux policies. The fs
   object context type was an old vestige that was introduced back in
   v2.6.12-rc2 but never really used.

 - A number of small changes that remove dead code, clean up some
   awkward bits, and generally improve the quality of the code. See the
   individual commit descriptions for more information.

Pull landlock updates from Mickaël Salaün:
 "Add support for Landlock to UML.

  To do this, this fixes the way hostfs manages inodes according to the
  underlying filesystem [1]. They are now properly handled as for other
  filesystems, which enables Landlock support (and probably other
  features).

  This also extends Landlock's tests with 6 pseudo filesystems,

Pull cgroup updates from Tejun Heo:

 - Whenever cpuset needs to rebuild sched_domain, it walked all tasks
   looking for DEADLINE tasks as they need to be accounted on the new
   domain. Walking all tasks can be expensive and there may not be any
   DEADLINE tasks at all. Task iteration is now omitted if there are no
   DEADLINE tasks

 - Fixes DEADLINE bandwidth misaccounting after task migration failures

 - When no controller is enabled, -Wstringop-overflow warning is
   triggered. The fix patch added an early exit which is too eager and
   got reverted for now. Will fix later

 - Everything else is minor cleanups

Pull ordered workqueue creation updates from Tejun Heo:
 "For historical reasons, unbound workqueues with max concurrency limit
  of 1 are considered ordered, even though the concurrency limit hasn't
  been system-wide for a long time.

  This creates ambiguity around whether ordered execution is actually
  required for correctness, which was actually confusing for e.g. btrfs
  (btrfs updates are being routed through the btrfs tree).

  There aren't that many users in the tree which use the combination and
  there are pending improvements to unbound workqueue affinity handling
  which will make inadvertent use of ordered workqueue a bigger loss.

  This clarifies the situation for most of them by updating the ones
  which require ordered execution to use alloc_ordered_workqueue().

  There are some conversions being routed through subsystem-specific
  trees and likely a few stragglers. Once they're all converted,
  workqueue can trigger a warning on unbound + @max_active==1 usages and
  eventually drop the implicit ordered behavior"

Pull s390 updates from Alexander Gordeev:

 - Fix the style of protected key API driver source: use x-mas tree for
   all local variable declarations

 - Rework protected key API driver to not use the struct pkey_protkey
   and pkey_clrkey anymore. Both structures have a fixed size buffer,
   but with the support of ECC protected key these buffers are not big
   enough. Use dynamic buffers internally and transparently for
   userspace

 - Add support for a new 'non CCA clear key token' with ECC clear keys
   supported: ECC P256, ECC P384, ECC P521, ECC ED25519 and ECC ED448.
   This makes it possible to derive a protected key from the ECC clear
   key input via PKEY_KBLOB2PROTK3 ioctl, while currently the only way
   to derive is via PCKMO instruction

 - The s390 PMU of PAI crypto and extension 1 NNPA counters use atomic_t
   for reference counting. Replace this with the proper data type
   refcount_t

 - Select ARCH_SUPPORTS_INT128, but limit this to clang for now, since
   gcc generates inefficient code, which may lead to stack overflows

 - Replace one-element array with flexible-array member in struct
   vfio_ccw_parent and refactor the rest of the code accordingly. Also,
   prefer struct_size() over sizeof() open- coded versions

 - Introduce OS_INFO_FLAGS_ENTRY pointing to a flags field and
   OS_INFO_FLAG_REIPL_CLEAR flag that informs a dumper whether the
   system memory should be cleared or not once dumped

 - Fix a hang when a user attempts to remove a VFIO-AP mediated device
   attached to a guest: add VFIO_DEVICE_GET_IRQ_INFO and
   VFIO_DEVICE_SET_IRQS IOCTLs and wire up the VFIO bus driver callback
   to request a release of the device

 - Fix calculation for R_390_GOTENT relocations for modules

 - Allow any user space process with CAP_PERFMON capability read and
   display the CPU Measurement facility counter sets

   and replace it with dynamically allocated structures created when a
   perf_event_open() system call is invoked or /dev/hwctr device is

to go together with a patchset that Vishal Moola had planned taking it
through the mm tree. By just having this patch, all NIOS2 builds are
broken.

Pull objtool updates from Ingo Molar:
 "Build footprint & performance improvements:

   - Reduce memory usage with CONFIG_DEBUG_INFO=y

     In the worst case of an allyesconfig+CONFIG_DEBUG_INFO=y kernel,
     DWARF creates almost 200 million relocations, ballooning objtool's
     peak heap usage to 53GB. These patches reduce that to 25GB.

     On a distro-type kernel with kernel IBT enabled, they reduce
     objtool's peak heap usage from 4.2GB to 2.8GB.

     These changes also improve the runtime significantly.

  Debuggability improvements:

   - Add the unwind_debug command-line option, for more extend unwinding
     debugging output
   - Limit unreachable warnings to once per function
   - Add verbose option for disassembling affected functions
   - Include backtrace in verbose mode
   - Detect missing __noreturn annotations
   - Ignore exc_double_fault() __noreturn warnings
   - Remove superfluous global_noreturns entries
   - Move noreturn function list to separate file
   - Add __kunit_abort() to noreturns

  Unwinder improvements:

   - Allow stack operations in UNWIND_HINT_UNDEFINED regions
   - drm/vmwgfx: Add unwind hints around RBP clobber

  Cleanups:

   - Move the x86 entry thunk restore code into thunk functions
   - x86/unwind/orc: Use swap() instead of open coding it
   - Remove unnecessary/unused variables
