From 8222d5910dae08213b6d9d4bc9a7f8502855e624 Mon Sep 17 00:00:00 2001 From: Herbert Xu Date: Thu, 9 Feb 2023 09:09:52 +0800 Subject: [PATCH 001/976] xfrm: Zero padding when dumping algos and encap When copying data to user-space we should ensure that only valid data is copied over. Padding in structures may be filled with random (possibly sensitve) data and should never be given directly to user-space. This patch fixes the copying of xfrm algorithms and the encap template in xfrm_user so that padding is zeroed.

Specifically adreno_runtime_resume() will eventually call a6xx_pm_resume() and that may try to resume the gmu. Let's grab the GMU lock as we're destroying the GMU. That will solve the race because a6xx_pm_resume() grabs the same lock. That makes the access of `gmu->initialized` in a6xx_gmu_resume() safe. We'll also return an error code in a6xx_gmu_resume() if we see that `gmu->initialized` was false. If this happens we'll bail out of the rest of a6xx_pm_resume(), which is good because the rest of that function is also not good to do if we're racing with a6xx_destroy().

The idea was suggested by Andrii Nakryiko [1] and initial patch was created by Alexei Starovoitov [2]. Currently the env->allow_uninit_stack is allowed for programs loaded by users with CAP_PERFMON or CAP_SYS_ADMIN capabilities. A number of test cases from verifier/*.c were expecting uninitialized stack access to be an error. These test cases were updated to execute in unprivileged mode (thus preserving the tests). The test progs/test_global_func10.c expected "invalid indirect read from stack" error message because of the access to uninitialized memory region. This error is no longer possible in privileged mode. The test is updated to provoke an error "invalid indirect access to stack" because of access to invalid stack address (such error is not verified by progs/test_global_func*.c series of tests). The following tests had to be removed because these can't be made unprivileged: - verifier/sock.c: - "sk_storage_get(map, skb->sk, &stack_value, 1): partially init stack_value" BPF_PROG_TYPE_SCHED_CLS programs are not executed in unprivileged mode. - verifier/var_off.c: - "indirect variable-offset stack access, max_off+size > max_initialized" - "indirect variable-offset stack access, uninitialized" These tests verify that access to uninitialized stack values is detected when stack offset is not a constant. However, variable stack access is prohibited in unprivileged mode, thus these tests are no longer valid. * * * Here is veristat log comparing this patch with current master on a set of selftest binaries listed in tools/testing/selftests/bpf/veristat.cfg and cilium BPF binaries (see [3]): $ ./veristat -e file,prog,states -C -f 'states_pct<-30' master.log current.log File Program States (A) States (B) States (DIFF) -------------------------- -------------------------- ---------- ---------- ---------------- bpf_host.o tail_handle_ipv6_from_host 349 244 -105 (-30.09%) bpf_host.o tail_handle_nat_fwd_ipv4 1320 895 -425 (-32.20%) bpf_lxc.o tail_handle_nat_fwd_ipv4 1320 895 -425 (-32.20%) bpf_sock.o cil_sock4_connect 70 48 -22 (-31.43%) bpf_sock.o cil_sock4_sendmsg 68 46 -22 (-32.35%) bpf_xdp.o tail_handle_nat_fwd_ipv4 1554 803 -751 (-48.33%) bpf_xdp.o tail_lb_ipv4 6457 2473 -3984 (-61.70%) bpf_xdp.o tail_lb_ipv6 7249 3908 -3341 (-46.09%) pyperf600_bpf_loop.bpf.o on_event 287 145 -142 (-49.48%) strobemeta.bpf.o on_event 15915 4772 -11143 (-70.02%) strobemeta_nounroll2.bpf.o on_event 17087 3820 -13267 (-77.64%) xdp_synproxy_kern.bpf.o syncookie_tc 21271 6635 -14636 (-68.81%) xdp_synproxy_kern.bpf.o syncookie_xdp 23122 6024 -17098 (-73.95%) -------------------------- -------------------------- ---------- ---------- ---------------- Note: I limited selection by states_pct<-30%. Inspection of differences in pyperf600_bpf_loop behavior shows that the following patch for the test removes almost all differences: - a/tools/testing/selftests/bpf/progs/pyperf.h + b/tools/testing/selftests/bpf/progs/pyperf.h @ -266,8 +266,8 @ int __on_event(struct bpf_raw_tracepoint_args *ctx) } if (event->pthread_match || !pidData->use_tls) { - void* frame_ptr; - FrameData frame; + void* frame_ptr = 0; + FrameData frame = {}; Symbol sym = {}; int cur_cpu = bpf_get_smp_processor_id(); W/o this patch the difference comes from the following pattern (for different variables): static bool get_frame_data(... FrameData *frame ...) { ... bpf_probe_read_user(&frame->f_code, ...); if (!frame->f_code) return false; ... bpf_probe_read_user(&frame->co_name, ...); if (frame->co_name) ...; } int __on_event(struct bpf_raw_tracepoint_args *ctx) { FrameData frame; ... get_frame_data(... &frame ...) // indirectly via a bpf_loop & callback ... } SEC("raw_tracepoint/kfree_skb") int on_event(struct bpf_raw_tracepoint_args* ctx) { ... ret |= __on_event(ctx); ret |= __on_event(ctx); ... } With regards to value `frame->co_name` the following is important: - Because of the conditional `if (!frame->f_code)` each call to __on_event() produces two states, one with `frame->co_name` marked as STACK_MISC, another with it as is (and marked STACK_INVALID on a first call). - The call to bpf_probe_read_user() does not mark stack slots corresponding to `&frame->co_name` as REG_LIVE_WRITTEN but it marks these slots as BPF_MISC, this happens because of the following loop in the check_helper_call(): for (i = 0; i < meta.access_size; i++) { err = check_mem_access(env, insn_idx, meta.regno, i, BPF_B, BPF_WRITE, -1, false); if (err) return err; } Note the size of the write, it is a one byte write for each byte touched by a helper. The BPF_B write does not lead to write marks for the target stack slot. - Which means that w/o this patch when second __on_event() call is verified `if (frame->co_name)` will propagate read marks first to a stack slot with STACK_MISC marks and second to a stack slot with STACK_INVALID marks and these states would be considered different.

However, some low-level HID drivers allocate a reduced amount of memory to their buffers (e.g. UHID only allocates UHID_DATA_MAX (4k) buffers), rending this check inadequate in some cases. In these circumstances, if the received report ends up being smaller than the proposed report size, the remainder of the buffer is zeroed. That is, the space between sizeof(csize) (size of the current report) and the rsize (size proposed i.e. Report Size * Report Count), which can be handled up to HID_MAX_BUFFER_SIZE (16k). Meaning that memset() shoots straight past the end of the buffer boundary and starts zeroing out in-use values, often resulting in calamity. This patch introduces a new variable into 'struct hid_ll_driver' where individual low-level drivers can over-ride the default maximum value of HID_MAX_BUFFER_SIZE (16k) with something more sympathetic to the interface.

APP1 continuously creates lots of small GEMs 2. APP2 triggers `drop_caches` 3. Shrinker starts to evict APP1 GEMs, while APP1 produces new purgeable GEMs 4. msm_gem_shrinker_scan() returns non-zero number of freed pages and causes shrinker to try shrink more 5. msm_gem_shrinker_scan() returns non-zero number of freed pages again, goto 4 6. The APP2 is blocked in `drop_caches` until APP1 stops producing purgeable GEMs To prevent this blocking scenario, check number of remaining pages that GPU shrinker couldn't release due to a GEM locking contention or shrinking rejection. If there are no remaining pages left to shrink, then there is no need to free up more pages and shrinker may break out from the loop. This problem was found during shrinker/madvise IOCTL testing of virtio-gpu driver. The MSM driver is affected in the same way.

With SK_RECLAIM_THRESHOLD checks gone number of calls to enter/leave memory pressure happen much more often. For TCP indirect calls are used. We can't remove the if-set-return short-circuit check in tcp_enter_memory_pressure because there are callers other than sk_enter_memory_pressure. Doing a check in the sk wrapper too reduces the indirect calls enough to recover some performance.

In this change, we add a new field 'initial_delay' for struct target which could be shared by other subcommands. And define target__enable_on_exec() which returns whether enable_on_exec should be set on normal cases.

Fix the error reported by Enguerrand de Ribaucourt in December 2022, "Some operations during the cable switch workaround modify the register LAN88XX_INT_MASK of the PHY. However, this register is specific to the LAN8835 PHY. For instance, if a DP8322I PHY is connected to the LAN7801, that register (0x19), corresponds to the LED and MAC address configuration, resulting in unapropriate behavior."

Later on, devices in the todo list are processed by netdev_run_todo(). netdev_run_todo() waits devices' reference count become 1 while rebdoadcasting NETDEV_UNREGISTER notification. When cfusbl_device_notify() is called with NETDEV_UNREGISTER multiple times, the parent device might be freed. This could cause UAF. Processing NETDEV_UNREGISTER multiple times also causes inbalance of reference count for the module. This patch fixes the issue by accepting only first NETDEV_UNREGISTER notification.

According to the Linux system call man page, 0 should be returned in this case. Therefore, in tcp_bpf_recvmsg_parser(), if the length is 0, directly return.

A mistake was made in using round_up(pos) for the end offset, because when pos points at the first byte of a block, it does not get rounded up to point to the end byte of the block. hence the punch range is short, and this leads to unexpected behaviour in certain cases in xfs_bmap_punch_delalloc_range. e.g. pos = 0 means we call xfs_bmap_punch_delalloc_range(0,0), so there is no previous extent and it rounds up the punch to the end of the delalloc extent it found at offset 0, not the end of the range given to xfs_bmap_punch_delalloc_range(). Fix this by handling the zero block offset case correctly.

This is expected cause a bus error exception on e.g. NULL pointer dereferencing when logging a kernel task has no workqueue associated. This bus error ought to be ignored. Our 030 bus error handler is ill equipped to deal with this: Whenever ssw indicates a kernel mode access on a data fault, we don't even attempt to handle the fault and instead always send a SEGV signal (or panic). As a result, the check for exception handling at the fault PC (buried in send_sig_fault() which gets called from do_page_fault() eventually) is never used. In contrast, both 040 and 060 access error handlers do not care whether a fault happened on supervisor mode access, and will call do_page_fault() on those, ultimately honoring the exception table. Add a check in bus_error030 to call do_page_fault() in case we do have an entry for the fault PC in our exception table. I had attempted a fix for this earlier in 2019 that did rely on testing pagefault_disabled() (see link below) to achieve the same thing, but this patch should be more generic. Tested on 030 Atari Falcon.

The locking there is unconditional, even if ->skip_locking and ->search_commit_root is set. It's not meant to be used for commit roots, so it always needs to do locking. So if another task is COWing a child node of the same root node and then needs to wait for block group caching to complete when trying to allocate a metadata extent, it deadlocks.

But the returned info is not enough to determine if a device is a seed. Commit a26d60dedf9a ("btrfs: sysfs: add devinfo/fsid to retrieve actual fsid from the device") exports the same value in sysfs so this is for parity with ioctl. Add a new member, fsid, into btrfs_ioctl_dev_info_args, and populate the member with fsid value. This should not cause any compatibility problem, following the combinations: - Old user space, old kernel - Old user space, new kernel User space tool won't even check the new member. - New user space, old kernel The kernel won't touch the new member, and user space tool should zero out its argument, thus the new member is all zero. User space tool can then know the kernel doesn't support this fsid reporting, and falls back to whatever they can. - New user space, new kernel Go as planned. Would find the fsid member is no longer zero, and trust its value.

IOW, the following: for (u32 i = 0; i < 0xdead; i++) { xdpf = xdp_convert_buff_to_frame(&xdp); xdp_convert_frame_to_buff(xdpf, &xdp); } shouldn't ever modify @xdpf's contents or the pointer itself. However, "live packet" code wrongly treats &xdp_frame as part of its context placed *before* the data_hard_start. With such flow, data_hard_start is sizeof(*xdpf) off to the right and no longer points to the XDP frame. Instead of replacing `sizeof(ctx)` with `offsetof(ctx, xdpf)` in several places and praying that there are no more miscalcs left somewhere in the code, unionize ::frm with ::data in a flex array, so that both starts pointing to the actual data_hard_start and the XDP frame actually starts being a part of it, i.e. a part of the headroom, not the context. A nice side effect is that the maximum frame size for this mode gets increased by 40 bytes, as xdp_buff::frame_sz includes everything from data_hard_start (-> includes xdpf already) to the end of XDP/skb shared info. Also update %MAX_PKT_SIZE accordingly in the selftests code. Leave it hardcoded for 64 bit && 4k pages, it can be made more flexible later on. Minor: align `&head->data` with how `head->frm` is assigned for consistency. Minor #2: rename 'frm' to 'frame' in &xdp_page_head while at it for clarity.

We do this so that fw_devlink can tell when a clock driver doesn't use the driver core framework to probe/initialize its device. This ensures fw_devlink doesn't block the consumers of such a clock provider indefinitely. However, some users of CLK_OF_DECLARE() macros don't use the same node that matches the macro as the node for the clock provider, but they initialize the entire node. To cover these cases, also mark the nodes that match the macros as initialized when the init callback function is called. An example of this is "stericsson,u8500-clks" that's handled using CLK_OF_DECLARE() and looks something like this: clocks { compatible = "stericsson,u8500-clks"; prcmu_clk: prcmu-clock { #clock-cells = <1>; }; prcc_pclk: prcc-periph-clock { #clock-cells = <2>; }; prcc_kclk: prcc-kernel-clock { #clock-cells = <2>; }; prcc_reset: prcc-reset-controller { #reset-cells = <2>; }; ... }; This patch makes sure that "clocks" is marked as initialized so that fw_devlink knows that all nodes under it have been initialized. If the driver creates struct devices for some of the subnodes, fw_devlink is smart enough to know to wait for those devices to probe, so no special handling is required for those cases.

The reason is that env_stack_push is never executed for the second VAR. if (!env_type_is_resolve_sink(env, var_type) && !env_type_is_resolved(env, var_type_id)) { env_stack_set_next_member(env, i + 1); return env_stack_push(env, var_type, var_type_id); } env_type_is_resolve_sink() changes its behaviour based on resolve_mode. For RESOLVE_PTR, we can simplify the if condition to the following: (btf_type_is_modifier() || btf_type_is_ptr) && !env_type_is_resolved() Since we're dealing with a VAR the clause evaluates to false. This is not sufficient to trigger the bug however. The log output and EINVAL are only generated if btf_type_id_size() fails. if (!btf_type_id_size(btf, &type_id, &type_size)) { btf_verifier_log_vsi(env, v->t, vsi, "Invalid type"); return -EINVAL; } Most types are sized, so for example a VAR referring to an INT is not a problem. The bug is only triggered if a VAR points at a modifier. Since we skipped btf_var_resolve that modifier was also never resolved, which means that btf_resolved_type_id returns 0 aka VOID for the modifier. This in turn causes btf_type_id_size to return NULL, triggering EINVAL. To summarise, the following conditions are necessary: - VAR pointing at PTR, STRUCT, UNION or ARRAY - Followed by a VAR pointing at TYPEDEF, VOLATILE, CONST, RESTRICT or TYPE_TAG The fix is to reset resolve_mode to RESOLVE_TBD before attempting to resolve a VAR from a DATASEC.

The documented correct check for "no more cpus in the cpumask" is to check for the result being equal or larger than the number of possible CPU ids, exactly _because_ we've always done those constant-sized cpumask scans using a widened type before. So the return value of a cpumask scan should be checked with if (cpu >= nr_cpu_ids) ... because the cpumask scan did not necessarily stop exactly *at* that maximum CPU id. But a few cases ended up instead using checks like if (cpu == nr_cpumask_bits) ... which used that internal "widened" number of bits. And that used to work pretty much by accident (ok, in this case "by accident" is simply because it matched the historical internal implementation of the cpumask scanning, so it was more of a "intentionally using implementation details rather than an accident"). But the extended constant-sized optimizations then did that internal implementation differently, and now that code that did things wrong but matched the old implementation no longer worked at all. Which then causes subsequent odd problems due to using what ends up being an invalid CPU ID. Most of these cases require either unusual hardware or special uses to hit, but the random.c one triggers quite easily. All you really need is to have a sufficiently small CONFIG_NR_CPUS value for the bit scanning optimization to be triggered, but not enough CPUs to then actually fill that widened cpumask. At that point, the cpumask scanning will return the NR_CPUS constant, which is _not_ the same as nr_cpumask_bits. This just does the mindless fix with sed -i 's/== nr_cpumask_bits/>= nr_cpu_ids/' to fix the incorrect uses. The ones in the SCSI lpfc driver in particular could probably be fixed more cleanly by just removing that repeated pattern entirely, but I am not emptionally invested enough in that driver to care.

But thanks to commit a666e5c05e7c ("dm: fix deadlock when swapping to encrypted device"), the limit_swap_bios target flag can also be used for dm-thin to avoid the recursive I/O when it is used as swap. Fix is to simply set ti->limit_swap_bios to true in both pool_ctr() and thin_ctr(). In my test, I create a dm-thin volume /dev/vg/swap and use it as swap device. Then I run fio on another dm-thin volume /dev/vg/main and use large --blocksize to trigger swap I/O onto /dev/vg/swap. The following fio command line is used in my test, fio --name recursive-swap-io --lockmem 1 --iodepth 128 \ --ioengine libaio --filename /dev/vg/main --rw randrw \ --blocksize 1M --numjobs 32 --time_based --runtime=12h Without this fix, the whole system can be locked up within 15 seconds. With this fix, there is no any deadlock or hung task observed after 2 hours of running fio. Furthermore, if blocksize is changed from 1M to 128M, after around 30 seconds fio has no visible I/O, and the out-of-memory killer message shows up in kernel message. After around 20 minutes all fio processes are killed and the whole system is back to being alive. This is exactly what is expected when recursive I/O happens on dm-thin volume when it is used as swap.

The initial commit adding vadc support assumed that the driver will use the unit address along with the node name to identify the channels. But this assumption is now broken by, commit 701c875aded8 ("iio: adc: qcom-spmi-adc5: Fix the channel name") that stripped unit address from channel names. This results in probe failure of the vadc driver: [ 8.380370] iio iio:device0: tried to double register : in_temp_pmic-die-temp_input [ 8.380383] qcom-spmi-adc5 c440000.spmi:pmic@0:adc@3100: Failed to register sysfs interfaces [ 8.380386] qcom-spmi-adc5: probe of c440000.spmi:pmic@0:adc@3100 failed with error -16 Hence, let's get rid of the assumption about drivers and rely on label property to uniquely identify the channels. The labels are derived from the schematics for each PMIC. For internal adc channels such as die and xo, the PMIC names are used as a prefix.

Linus proposed to avoid any use of the list iterator variable after the loop, in the attempt to move the list iterator variable declaration into the macro to avoid any potential misuse after the loop [1].

The VHD/VHDX file format is a sparse format where real disk space on the host is assigned in chunks that the VHD/VHDX file format calls the BlockSize. This BlockSize is not to be confused with the 512-byte (or 4096-byte) sector size of the underlying storage device. The default block size for a new VHD/VHDX file is 32 Mbytes. When a guest VM touches any disk space within a 32 Mbyte chunk of the VHD/VHDX file, Hyper-V allocates 32 Mbytes of real disk space for that section of the VHD/VHDX. Similarly, if a discard operation is done that covers an entire 32 Mbyte chunk, Hyper-V will free the real disk space for that portion of the VHD/VHDX. This BlockSize is surfaced in Linux as the "discard_granularity" in /sys/block/sd/queue, which makes sense. Hyper-V also has differencing disks that can overlay a VHD/VHDX file to capture changes to the VHD/VHDX while preserving the original VHD/VHDX. One example of this differencing functionality is for VM snapshots. When a snapshot is created, a differencing disk is created. If the snapshot is rolled back, Hyper-V can just delete the differencing disk, and the VM will see the original disk contents at the time the snapshot was taken. Differencing disks are used in other scenarios as well. The BlockSize for a differencing disk defaults to 2 Mbytes, not 32 Mbytes. The smaller default is used because changes to differencing disks are typically scattered all over, and Hyper-V doesn't want to allocate 32 Mbytes of real disk space for a stray write here or there. The smaller BlockSize provides more efficient use of real disk space. When a differencing disk is added to a VHD/VHDX, Hyper-V reports UNIT_ATTENTION with a sense code indicating "Operating parameters have changed", because the value of discard_granularity should be changed to 2 Mbytes. When the differencing disk is removed, discard_granularity should be changed back to 32 Mbytes. However, current code simply reports a message from scsi_report_sense() and the value of /sys/block/sd/queue/discard_granularity is not updated. The message isn't very actionable by a sysadmin. Fix this by having the storvsc driver check for the sense code indicating that the underly VHD/VHDX block size has changed, and do a rescan of the device to pick up the new discard_granularity. With this change the entire transition to/from differencing disks is handled automatically and transparently, with no confusing messages being output.

After that, the sd driver overwrites the value in sd_zbc_read_zone() with the physical block size, since ZBC/ZAC requires this for host-managed disks. Between the calls to disk_set_zoned() and sd_zbc_read_zone(), there exists a window where the attribute shows the logical block size as the zone_write_granularity value, which is wrong for host-managed disks. The duration of the window is from 20ms to 200ms, depending on report zone command execution time. To avoid the wrong zone_write_granularity value between disk_set_zoned() and sd_zbc_read_zone(), modify the value not in sd_zbc_read_zone() but just after disk_set_zoned() call.

This fixes in-place decompression for x86-64 kernel decompression. It uses a bound of 131072 + (uncompressed_size >> 8), which can be violated after upstream commit 6a7ede3d [1], as zstd can use part of the output buffer as temporary storage, and without this patch needs a bound of ~262144. The fix is for zstd to detect that the input and output buffers overlap, so that zstd knows it can't use the overlapping portion of the output buffer as tempoary storage. If the margin is not large enough, this will ensure that zstd will fail the decompression, rather than overwriting part of the input data, and causing corruption. This fix has been landed upstream and is in release v1.5.4. That commit also adds unit and fuzz tests to verify that the margin we use is respected, and correct. That means that the fix is well tested upstream. I have not been able to reproduce the potential bug in x86-64 kernel decompression locally, nor have I recieved reports of failures to decompress the kernel. It is possible that compression saves enough space to make it very hard for the issue to appear. I've boot tested the zstd compressed kernel on x86-64 and i386 with this patch, which uses in-place decompression, and sanity tested zstd compression in btrfs / squashfs to make sure that we don't see any issues, but other uses of zstd shouldn't be affected, because they don't use in-place decompression. Thanks to Vasily Gorbik for debugging a related issue on s390, which was triggered by the same commit, but was a bug in how __decompress() was called [2]. And to Sasha Levin for the CC alerting me of the issue.

Even if we assume Uniform Hashing, a bucket often reachs 8 chained items while the load factor of the hash table is smaller than 0.5 With a limit of 16, we reach load factors of 3. With a limit of 32, we reach load factors of 11. With a limit of 40, we reach load factors of 15. With a limit of 50, we reach load factors of 24. This patch changes MIN_CHAINLEN to 50, to minimize risks.

Part of this broken ACPI code is that sometimes these boards have _AEI ACPI GPIO event handlers which are broken. So far this has been dealt with in the platform/x86/x86-android-tablets.c module, which contains various workarounds for these devices, by it calling acpi_gpiochip_free_interrupts() on gpiochip-s with troublesome handlers to disable the handlers. But in some cases this is too late, if the handlers are of the edge type then gpiolib-acpi.c's code will already have run them at boot. This can cause issues such as GPIOs ending up as owned by "ACPI:OpRegion", making them unavailable for drivers which actually need them. Boards with these broken ACPI tables are already listed in drivers/acpi/x86/utils.c for e.g. acpi_quirk_skip_i2c_client_enumeration(). Extend the quirks mechanism for a new acpi_quirk_skip_gpio_event_handlers() helper, this re-uses the DMI-ids rather then having to duplicate the same DMI table in gpiolib-acpi.c . Also add the new ACPI_QUIRK_SKIP_GPIO_EVENT_HANDLERS quirk to existing boards with troublesome ACPI gpio event handlers, so that the current acpi_gpiochip_free_interrupts() hack can be removed from x86-android-tablets.c .

The BAR size defined in hardware specifications is 2MB. The commit 5947b2726beb6 ("ASoC: SOF: Intel: Check the bar size before remapping") tried to find the BAR size by querying the resource length instead of a pre-canned value, but by requesting the size for index 3 it only gets the size of the IRAM. That's obviously wrong and prevents the probe from proceeding. This commit attempted to fix an issue in a fuzzing/simulated environment but created another on actual devices, so the best course of action is to revert that change.

This means that the early bit clock feature required for certain codecs will be broken. Fix this by saving the config flags sent during BE DAI hw_params and reusing it when the DAI_CONFIG IPC is sent after the DAI widget is set up. Also, free the DAI config before the widget is freed. The DAI_CONFIG IPC sent during the sof_widget_free() does not have the DAI index information. So, save the dai_index in the config during hw_params and reuse it during hw_free. For IPC4, do not clear the node ID during hw_free. It will be needed for freeing the group_ida during unprepare.

A simple solution would be to change the definition, but unfortunately the ASoC topology framework only supports up to 32 bit tokens. This patch suggests breaking the 64 bit value in low and high parts, with only the low-part extracted from topology and high-part only zeroes. Since the curve duration is represented in hundred of nanoseconds, we can still represent a 400s ramp, which is just fine. The defacto ABI change has no effect on existing users since the IPC4 firmware has not been released just yet.

However, Yury correctly points out that while "bitmap_set()" does indeed only set bits up to the required bitmap size, it doesn't _clear_ bits above that size, so the upper bits would still not have well-defined values. Now, none of this should really matter, since any bits set past 'nr_cpu_ids' should always be ignored in the first place. Yes, the bit scanning functions might return them as a result, but since users should always consider the ">= nr_cpu_ids" condition to mean "no more bits", that shouldn't have any actual effect (see previous commit 8ca09d5fa354 "cpumask: fix incorrect cpumask scanning result checks"). But let's just do it right, the way the code was _intended_ to work. We have had enough lazy code that works but bites us in the *rse later (again, see previous commit) that there's no reason to not just do this properly. It turns out that "bitmap_fill()" gets this all right for the complex case, and really only fails for the inlined optimized case that just fills the whole word. And while we could just fix bitmap_fill() to use the proper last word mask, there's two issues with that: - the cpumask case wants to do the _optimization_ based on "NR_CPUS is a small constant", but then wants to do the actual bit _fill_ based on "nr_cpu_ids" that isn't necessarily that same constant - we have lots of non-cpumask users of bitmap_fill(), and while they hopefully don't care, and probably would want the proper semantics anyway ("only set bits up to the limit"), I do not want the cpumask changes to impact other parts So this ends up just doing the single-word optimization by hand in the cpumask code. If our cpumask is fundamentally limited to a single word, just do the proper "fill in that word" exactly. And if it's the more complex multi-word case, then the generic bitmap_fill() will DTRT. This is all an example of how our bitmap function optimizations really are somewhat broken. They conflate the "this is size of the bitmap" optimizations with the actual bit(s) we want to set. In many cases we really want to have the two be separate things: sometimes we base our optimizations on the size of the whole bitmap ("I know this whole bitmap fits in a single word, so I'll just use single-word accesses"), and sometimes we base them on the bit we are looking at ("this is just acting on bits that are in the first word, so I'll use single-word accesses"). Notice how the end result of the two optimizations are the same, but the way we get to them are quite different. And all our cpumask optimization games are really about that fundamental distinction, and we'd often really want to pass in both the "this is the bit I'm working on" (which _can_ be a small constant but might be variable), and "I know it's in this range even if it's variable" (based on CONFIG_NR_CPUS). So this cpumask_setall() implementation just makes that explicit. It checks the "I statically know the size is small" using the known static size of the cpumask (which is what that 'small_cpumask_bits' is all about), but then sets the actual bits using the exact number of cpus we have (ie 'nr_cpumask_bits') Of course, in a perfect world, the compiler would have done all the range analysis (possibly with help from us just telling it that "this value is always in this range"), and would do all of this for us. But that is not the world we live in. While we dream of that perfect world, this does that manual logic to make it all work out. And this was a very long explanation for a small code change that shouldn't even matter.

Userspace is expected to read the EDID and set an appropriate HDR_OUTPUT_METADATA. In drm_parse_hdr_metadata_block the kernel reads the supported EOTFs from the EDID and stores them in the drm_connector->hdr_sink_metadata. While doing so it also filters the EOTFs to the EOTFs the kernel knows about. When an HDR_OUTPUT_METADATA is set it then checks to make sure the EOTF is a supported EOTF. In cases where the kernel doesn't know about a new EOTF this check will fail, even if the EDID advertises support. Since it is expected that userspace reads the EDID to understand what the display supports it doesn't make sense for DRM to block an HDR_OUTPUT_METADATA if it contains an EOTF the kernel doesn't understand. This comes with the added benefit of future-proofing metadata support. If the spec defines a new EOTF there is no need to update DRM and an compositor can immediately make use of it.

This happens if for the new allocated block group, in the same transaction that created the block group, we have tasks allocating extents from it as well as tasks removing extents from it. For example: 1) Task A creates a metadata block group X; 2) Two extents are allocated from block group X, so its "used" field is updated to 32K, and its "commit_used" field remains as 0; 3) Transaction commit starts, by some task B, and it enters btrfs_start_dirty_block_groups(). There it tries to update the block group item for block group X, which currently has its "used" field with a value of 32K. But that fails since the block group item was not yet inserted, and so on failure update_block_group_item() sets the "commit_used" field of the block group back to 0; 4) The block group item is inserted by task A, when for example btrfs_create_pending_block_groups() is called when releasing its transaction handle. This results in insert_block_group_item() inserting the block group item in the extent tree (or block group tree), with a "used" field having a value of 32K, but without updating the "commit_used" field in the block group, which remains with value of 0; 5) The two extents are freed from block X, so its "used" field changes from 32K to 0; 6) The transaction commit by task B continues, it enters btrfs_write_dirty_block_groups() which calls update_block_group_item() for block group X, and there it decides to skip the block group item update, because "used" has a value of 0 and "commit_used" has a value of 0 too. As a result, we end up with a block item having a 32K "used" field but no extents allocated from it. When this issue happens, a btrfs check reports an error like this: [1/7] checking root items [2/7] checking extents block group [1104150528 1073741824] used 39796736 but extent items used 0 ERROR: errors found in extent allocation tree or chunk allocation (...) Fix this by making insert_block_group_item() update the block group's "commit_used" field.

Two deadlock bugs were reported for the migrate_pages() batching series. Thanks Hugh and Pengfei. Analysis shows that if we have locked some other folios except the one we are migrating, it's not safe in general to wait synchronously, for example, to wait the writeback to complete or wait to lock the buffer head. So 1/3 fixes the deadlock in a simple way, where the batching support for the synchronous migration is disabled. The change is straightforward and easy to be understood. While 3/3 re-introduce the batching for synchronous migration via trying to migrate asynchronously in batch optimistically, then fall back to migrate synchronously one by one for fail-to-migrate folios. Test shows that this can restore the TLB flushing batching performance for synchronous migration effectively. This patch (of 3): Two deadlock bugs were reported for the migrate_pages() batching series. Thanks Hugh and Pengfei!

While the loop worker task which writes back the folio B is waiting to lock the shmem folio A, because the folio A backs the folio B in the loop device. Thus deadlock is triggered. In general, if we have locked some other folios except the one we are migrating, it's not safe to wait synchronously, for example, to wait the writeback to complete or wait to lock the buffer head. To fix the deadlock, in this patch, we avoid to batch the page migration except for MIGRATE_ASYNC mode. In MIGRATE_ASYNC mode, synchronous waiting is avoided. The fix can be improved further. We will do that as soon as possible.

Otherwise deadlock may be triggered. This make it hard to batch the synchronous migration directly. This patch re-enables batching synchronous migration via trying to migrate in batch asynchronously firstly. And any folios that are failed to be migrated asynchronously will be migrated synchronously one by one. Test shows that this can restore the TLB flushing batching performance for synchronous migration effectively.

The xfstests include: ext4/057, 058, and 307; generic/013, 051, 068, 070, 076, 078, 083, 232, 269, 270, 390, 461, 475, 476, 482, 579, 585, 589, 626, 631, and 650. In this situation, the warning message indicates a bug in the code that performs the RENAME_WHITEOUT operation on a directory entry that has been stored inline. It doesn't detect that the directory is stored inline, and incorrectly attempts to compute a dirent block checksum on the whiteout inode when creating it. This attempt fails as a result of the integrity checking in get_dirent_tail (usually due to a failure to match the EXT4_FT_DIR_CSUM magic cookie), and the warning message is then emitted. Fix this by simply collecting the inlined data state at the time the search for the source directory entry is performed. Existing code handles the rest, and this is sufficient to eliminate all spurious warning messages produced by the tests above. Go one step further and do the same in the code that resets the source directory entry in the event of failure. The inlined state should be present in the "old" struct, but given the possibility of a race there's no harm in taking a conservative approach and getting that information again since the directory entry is being reread anyway.

To query mappings for a subrange of the device, the starting byte of the range is written to fsmap_head.fmh_keys[0].fmr_physical and the last byte of the range goes in fsmap_head.fmh_keys[1].fmr_physical. IOWs, to query what mappings overlap with bytes 3-14 of /dev/sda, you'd set the inputs as follows: fmh_keys[0] = { .fmr_device = major(8, 0), .fmr_physical = 3}, fmh_keys[1] = { .fmr_device = major(8, 0), .fmr_physical = 14}, Which would return you whatever is mapped in the 12 bytes starting at physical offset 3. The crash is due to insufficient range validation of keys[1] in ext4_getfsmap_datadev. On 1k-block filesystems, block 0 is not part of the filesystem, which means that s_first_data_block is nonzero. ext4_get_group_no_and_offset subtracts this quantity from the blocknr argument before cracking it into a group number and a block number within a group. IOWs, block group 0 spans blocks 1-8192 (1-based) instead of 0-8191 (0-based) like what happens with larger blocksizes. The net result of this encoding is that blocknr < s_first_data_block is not a valid input to this function. The end_fsb variable is set from the keys that are copied from userspace, which means that in the above example, its value is zero. That leads to an underflow here: blocknr = blocknr - le32_to_cpu(es->s_first_data_block); The division then operates on -1: offset = do_div(blocknr, EXT4_BLOCKS_PER_GROUP(sb)) >> EXT4_SB(sb)->s_cluster_bits; Leaving an impossibly large group number (2^32-1) in blocknr. ext4_getfsmap_check_keys checked that keys[0].fmr_physical and keys[1].fmr_physical are in increasing order, but ext4_getfsmap_datadev adjusts keys[0].fmr_physical to be at least s_first_data_block. This implies that we have to check it again after the adjustment, which is the piece that I forgot.

This happens because they set PF_NO_SETAFFINITY as part of their creation, as io-wq organizes workers into groups based on what CPU they are running on. However, this is purely an optimization and not a functional requirement. We can allow setting affinity, and just lazily update our worker to wqe mappings. If a given io-wq thread times out, it normally exits if there's no more work to do. The exception is if it's the last worker available. For the timeout case, check the affinity of the worker against group mask and exit even if it's the last worker. New workers should be created with the right mask and in the right location.

The non WEP key stores can store keys with indexes 0 - BIP_MAX_KEYID, this means that they should be an array with BIP_MAX_KEYID + 1 entries. But some of the arrays where just BIP_MAX_KEYID entries big. While one other array was hardcoded to a size of 6 entries, instead of using the BIP_MAX_KEYID define. 2. The rtw_cfg80211_set_encryption() and wpa_set_encryption() functions index check where checking that the passed in key-index would fit inside both the WEP key store (which only has 4 entries) as well as in the non WEP key stores. This breaks any attempts to set non WEP keys with index 4 or 5. Issue 2. specifically breaks wifi connection with some access points which advertise PMF support. Without this fix connecting to these access points fails with the following wpa_supplicant messages: nl80211: kernel reports: key addition failed wlan0: WPA: Failed to configure IGTK to the driver wlan0: RSN: Failed to configure IGTK wlan0: CTRL-EVENT-DISCONNECTED bssid=... reason=1 locally_generated=1 Fix 1. by using the right size for the key-stores. After this 2. can safely be fixed by checking the right max-index value depending on the used algorithm, fixing wifi not working with some PMF capable APs.

And the keyword in there is 'stable': the current thread pointer never changes as far as a single thread is concerned. Even if when a thread is preempted, or moved to another CPU, or even across an explicit call 'schedule()' that thread will still have the same value for 'current'. It is, after all, the kernel base pointer to thread-local storage. That's why it's stable to begin with, but it's also why it's important enough that we have that special 'this_cpu_read_stable()' access for it. So this is all done very intentionally to allow the compiler to treat 'current' as a value that never visibly changes, so that the compiler can do CSE and combine multiple different 'current' accesses into one. However, there is obviously one very special situation when the currently running thread does actually change: inside the scheduler itself. So the scheduler code paths are special, and do not have a 'current' thread at all. Instead there are _two_ threads: the previous and the next thread - typically called 'prev' and 'next' (or prev_p/next_p) internally. So this is all actually quite straightforward and simple, and not all that complicated. Except for when you then have special code that is run in scheduler context, that code then has to be aware that 'current' isn't really a valid thing. Did you mean 'prev'? Did you mean 'next'? In fact, even if then look at the code, and you use 'current' after the new value has been assigned to the percpu variable, we have explicitly told the compiler that 'current' is magical and always stable. So the compiler is quite free to use an older (or newer) value of 'current', and the actual assignment to the percpu storage is not relevant even if it might look that way. Which is exactly what happened in the resctl code, that blithely used 'current' in '__resctrl_sched_in()' when it really wanted the new process state (as implied by the name: we're scheduling 'into' that new resctl state). And clang would end up just using the old thread pointer value at least in some configurations. This could have happened with gcc too, and purely depends on random compiler details. Clang just seems to have been more aggressive about moving the read of the per-cpu current_task pointer around. The fix is trivial: just make the resctl code adhere to the scheduler rules of using the prev/next thread pointer explicitly, instead of using 'current' in a situation where it just wasn't valid. That same code is then also used outside of the scheduler context (when a thread resctl state is explicitly changed), and then we will just pass in 'current' as that pointer, of course. There is no ambiguity in that case. The fix may be trivial, but noticing and figuring out what went wrong was not. The credit for that goes to Stephane Eranian.

Arınç reports that the GMAC1 attached to port 5 receives corrupted frames, unless port 6 (attached to GMAC0) has been brought up by the driver. This is true regardless of whether port 5 is used as a user port or as a CPU port (carrying DSA tags). Offline debugging (blind for me) which began in the linked thread showed experimentally that the configuration done by the driver for port 6 contains a step which is needed by port 5 as well - the write to CORE_GSWPLL_GRP2 (note that I've no idea as to what it does, apart from the comment "Set core clock into 500Mhz"). Prints put by Arınç show that the reset value of CORE_GSWPLL_GRP2 is RG_GSWPLL_POSDIV_500M(1) | RG_GSWPLL_FBKDIV_500M(40) (0x128), both on the MCM MT7530 from the MT7621 SoC, as well as on the standalone MT7530 from MT7623NI Bananapi BPI-R2. Apparently, port 5 on the standalone MT7530 can work under both values of the register, while on the MT7621 SoC it cannot. The call path that triggers the register write is: mt753x_phylink_mac_config() for port 6 -> mt753x_pad_setup() -> mt7530_pad_clk_setup() so this fully explains the behavior noticed by Arınç, that bringing port 6 up is necessary. The simplest fix for the problem is to extract the register writes which are needed for both port 5 and 6 into a common mt7530_pll_setup() function, which is called at mt7530_setup() time, immediately after switch reset. We can argue that this mirrors the code layout introduced in mt7531_setup() by commit 42bc4fafe359 ("net: mt7531: only do PLL once after the reset"), in that the PLL setup has the exact same positioning, and further work to consolidate the separate setup() functions is not hindered. Testing confirms that: - the slight reordering of writes to MT7530_P6ECR and to CORE_GSWPLL_GRP1 / CORE_GSWPLL_GRP2 introduced by this change does not appear to cause problems for the operation of port 6 on MT7621 and on MT7623 (where port 5 also always worked) - packets sent through port 5 are not corrupted anymore, regardless of whether port 6 is enabled by phylink or not (or even present in the device tree) My algorithm for determining the Fixes: tag is as follows. Testing shows that some logic from mt7530_pad_clk_setup() is needed even for port 5. Prior to commit ca366d6c889b ("net: dsa: mt7530: Convert to PHYLINK API"), a call did exist for all phy_is_pseudo_fixed_link() ports - so port 5 included. That commit replaced it with a temporary "Port 5 is not supported!" comment, and the following commit 38f790a80560 ("net: dsa: mt7530: Add support for port 5") replaced that comment with a configuration procedure in mt7530_setup_port5() which was insufficient for port 5 to work. I'm laying the blame on the patch that claimed support for port 5, although one would have also needed the change from commit c3b8e07909db ("net: dsa: mt7530: setup core clock even in TRGMII mode") for the write to be performed completely independently from port 6's configuration. Thanks go to Arınç for describing the problem, for debugging and for testing.

Issue is that queue_oob() calls maybe_add_creds() which potentially holds a reference on a pid. But skb->destructor is not set (either directly or by calling unix_scm_to_skb()) This means that subsequent kfree_skb() or consume_skb() would leak this reference. In this fix, I chose to fully support scm even for the OOB message.

Also the rtl8xxxu driver supports way more devices, and is a fraction of the overall size, making this a much better overall solution. Thanks to the r8188eu developers and maintainers and reviewers over the years, your work allowed Linux users to use their hardware before the real driver was implemented properly.

This was due to the fact that there was a GUCTL2 bit field which enabled synchronous completion of the end transfer command once the CMDACT bit was cleared in the DEPCMD register. Since this bit does not exist for all controller revisions and the current implementation heavily relies on utizling the EndTransfer command completion interrupt, add the delay back in for uses where the interrupt on completion bit is not set, and increase the duration to 1ms for the controller to complete the command. An issue was seen where the USB request buffer was unmapped while the DWC3 controller was still accessing the TRB. However, it was confirmed that the end transfer command was successfully submitted. (no end transfer timeout) In situations, such as dwc3_gadget_soft_disconnect() and __dwc3_gadget_ep_disable(), the dwc3_remove_request() is utilized, which will issue the end transfer command, and follow up with dwc3_gadget_giveback(). At least for the USB ep disable path, it is required for any pending and started requests to be completed and returned to the function driver in the same context of the disable call. Without the GUCTL2 bit, it is not ensured that the end transfer is completed before the buffers are unmapped.

This can cause a deadlock during reboot, as evidenced by the following blocked task observed on my machine: task:reboot state:D stack:0 pid:2827 ppid:569 flags:0x0000000c Call trace: __switch_to+0xc8/0x140 __schedule+0x2f0/0x7c0 schedule+0x60/0xd0 schedule_timeout+0x180/0x1d4 wait_for_completion+0x78/0x180 snd_card_free+0x90/0xa0 g_audio_cleanup+0x2c/0x64 afunc_unbind+0x28/0x60 ... kernel_restart+0x4c/0xac __do_sys_reboot+0xcc/0x1ec __arm64_sys_reboot+0x28/0x30 invoke_syscall+0x4c/0x110 ...

It is intended to run on a Linux system that has USB device-side +hardware such as boards with an OTG port. + +On the device system, once the driver is bound it appears as a V4L2 device with +the output capability. + +On the host side (once connected via USB cable), a device running the UVC Gadget +driver *and controlled by an appropriate userspace program* should appear as a UVC +specification compliant camera, and function appropriately with any program +designed to handle them. The userspace program running on the device system can +queue image buffers from a variety of sources to be transmitted via the USB +connection. Typically this would mean forwarding the buffers from a camera sensor +peripheral, but the source of the buffer is entirely dependent on the userspace +companion program. + +Configuring the device kernel +----------------------------- +The Kconfig options USB_CONFIGFS, USB_LIBCOMPOSITE, USB_CONFIGFS_F_UVC and +USB_F_UVC must be selected to enable support for the UVC gadget. + +Configuring the gadget through configfs +--------------------------------------- +The UVC Gadget expects to be configured through configfs using the UVC function. +This allows a significant degree of flexibility, as many of a UVC device's +settings can be controlled this way. + +Not all of the available attributes are described here. For a complete enumeration +see Documentation/ABI/testing/configfs-usb-gadget-uvc + +Assumptions +~~~~~~~~~~~ +This section assumes that you have mounted configfs at `/sys/kernel/config` and +created a gadget as `/sys/kernel/config/usb_gadget/g1`. + +The UVC Function +~~~~~~~~~~~~~~~~ + +The first step is to create the UVC function: + +.. code-block:: bash + + # These variables will be assumed throughout the rest of the document + CONFIGFS="/sys/kernel/config" + GADGET="$CONFIGFS/usb_gadget/g1" + FUNCTION="$GADGET/functions/uvc.0" + + mkdir -p $FUNCTION + +Formats and Frames +~~~~~~~~~~~~~~~~~~ + +You must configure the gadget by telling it which formats you support, as well +as the frame sizes and frame intervals that are supported for each format. In +the current implementation there is no way for the gadget to refuse to set a +format that the host instructs it to set, so it is important that this step is +completed *accurately* to ensure that the host never asks for a format that +can't be provided. + +Formats are created under the streaming/uncompressed and streaming/mjpeg configfs +groups, with the framesizes created under the formats in the following +structure: + +:: + + uvc.0 + + | + + streaming + + | + + mjpeg + + | | + | + mjpeg + + | | + | + 720p + | | + | + 1080p + | + + uncompressed + + | + + yuyv + + | + + 720p + | + + 1080p + +Each frame can then be configured with a width and height, plus the maximum +buffer size required to store a single frame, and finally with the supported +frame intervals for that format and framesize. Width and height are enumerated in +units of pixels, frame interval in units of 100ns. To create the structure +above with 2, 15 and 100 fps frameintervals for each framesize for example you +might do: + +.. code-block:: bash + + create_frame() { + # Example usage: + # create_frame + + WIDTH=$1 + HEIGHT=$2 + FORMAT=$3 + NAME=$4 + + wdir=$FUNCTION/streaming/$FORMAT/$NAME/${HEIGHT}p + + mkdir -p $wdir + echo $WIDTH > $wdir/wWidth + echo $HEIGHT > $wdir/wHeight + echo $(( $WIDTH * $HEIGHT * 2 )) > $wdir/dwMaxVideoFrameBufferSize + cat < $wdir/dwFrameInterval + 666666 + 100000 + 5000000 + EOF + } + + create_frame 1280 720 mjpeg mjpeg + create_frame 1920 1080 mjpeg mjpeg + create_frame 1280 720 uncompressed yuyv + create_frame 1920 1080 uncompressed yuyv + +The only uncompressed format currently supported is YUYV, which is detailed at +Documentation/userspace-api/media/v4l/pixfmt-packed.yuv.rst. + +Color Matching Descriptors +~~~~~~~~~~~~~~~~~~~~~~~~~~ +It's possible to specify some colometry information for each format you create. +This step is optional, and default information will be included if this step is +skipped; those default values follow those defined in the Color Matching Descriptor +section of the UVC specification. + +To create a Color Matching Descriptor, create a configfs item and set its three +attributes to your desired settings and then link to it from the format you wish +it to be associated with: + +.. code-block:: bash + + # Create a new Color Matching Descriptor + + mkdir $FUNCTION/streaming/color_matching/yuyv + pushd $FUNCTION/streaming/color_matching/yuyv + + echo 1 > bColorPrimaries + echo 1 > bTransferCharacteristics + echo 4 > bMatrixCoefficients + + popd + + # Create a symlink to the Color Matching Descriptor from the format's config item + ln -s $FUNCTION/streaming/color_matching/yuyv $FUNCTION/streaming/uncompressed/yuyv + +For details about the valid values, consult the UVC specification.

It's possible to +change the attribute settings for the default descriptor, so bear in mind that if +you do that you are altering the defaults for any format that does not link to +a different one. + + +Header linking +~~~~~~~~~~~~~~ + +The UVC specification requires that Format and Frame descriptors be preceded by +Headers detailing things such as the number and cumulative size of the different +Format descriptors that follow. This and similar operations are acheived in +configfs by linking between the configfs item representing the header and the +config items representing those other descriptors, in this manner: + +.. code-block:: bash + + mkdir $FUNCTION/streaming/header/h + + # This section links the format descriptors and their associated frames + # to the header + cd $FUNCTION/streaming/header/h + ln -s ../../uncompressed/yuyv + ln -s ../../mjpeg/mjpeg + + # This section ensures that the header will be transmitted for each + # speed's set of descriptors.

The meaning of those control requests is +entirely implementation dependent, but may be used to control settings outside +of the UVC specification (for example enabling or disabling video effects). An +XU can be inserted into the UVC unit chain or left free-hanging. + +Configuring an extension unit involves creating an entry in the appropriate +directory and setting its attributes appropriately, like so: + +.. code-block:: bash + + mkdir $FUNCTION/control/extensions/xu.0 + pushd $FUNCTION/control/extensions/xu.0 + + # Set the bUnitID of the Processing Unit as the source for this + # Extension Unit + echo 2 > baSourceID + + # Set this XU as the source of the default output terminal. This inserts + # the XU into the UVC chain between the PU and OT such that the final + # chain is IT > PU > XU.0 > OT + cat bUnitID > ../../terminal/output/default/baSourceID + + # Flag some controls as being available for use. The bmControl field is + # a bitmap with each bit denoting the availability of a particular + # control. For example to flag the 0th, 2nd and 3rd controls available: + echo 0x0d > bmControls + + # Set the GUID; this is a vendor-specific code identifying the XU. + echo -e -n "\x01\x02\x03\x04\x05\x06\x07\x08\x09\x0a\x0b\x0c\x0d\x0e\x0f\x10" > guidExtensionCode + + popd + +The bmControls attribute and the baSourceID attribute are multi-value attributes. +This means that you may write multiple newline separated values to them. For +example to flag the 1st, 2nd, 9th and 10th controls as being available you would +need to write two values to bmControls, like so: + +.. code-block:: bash + + cat << EOF > bmControls + 0x03 + 0x03 + EOF + +The multi-value nature of the baSourceID attribute belies the fact that XUs can +be multiple-input, though note that this currently has no significant effect. + +The bControlSize attribute reflects the size of the bmControls attribute, and +similarly bNrInPins reflects the size of the baSourceID attributes. Both +attributes are automatically increased / decreased as you set bmControls and +baSourceID. It is also possible to manually increase or decrease bControlSize +which has the effect of truncating entries to the new size, or padding entries +out with 0x00, for example: + +:: + + $ cat bmControls + 0x03 + 0x05 + + $ cat bControlSize + 2 + + $ echo 1 > bControlSize + $ cat bmControls + 0x03 + + $ echo 2 > bControlSize + $ cat bmControls + 0x03 + 0x00 + +bNrInPins and baSourceID function in the same way. + +Custom Strings Support +~~~~~~~~~~~~~~~~~~~~~~ + +String descriptors that provide a textual description for various parts of a +USB device can be defined in the usual place within USB configfs, and may then +be linked to from the UVC function root or from Extension Unit directories to +assign those strings as descriptors: + +.. code-block:: bash + + # Create a string descriptor in us-EN and link to it from the function + # root.

This is intended to support delayed response control set requests for +UVC (which should respond through the interrupt endpoint rather than tying up +endpoint 0). At present support for sending data through this endpoint is missing +and so it is left disabled to avoid confusion.

In con_font_get, we were not checking that it is within the maximum height value, and thus userland could make the vc->vc_sw->con_font_get(vc, &font, vpitch); call possibly overflow the allocated max_font_size bytes, and the copy_to_user(op->data, font.data, c) call possibly read out of that allocated buffer. By checking vpitch against max_font_height, the max_font_size buffer will always be large enough for the vc->vc_sw->con_font_get(vc, &font, vpitch) call (since we already prevent loading a font larger than that), and c = (font.width+7)/8 * vpitch * font.charcount will always remain below max_font_size.

Now that all in-tree drivers are converted to the temporary .probe_new() callback, .probe() can be modified to match the desired prototype. Now that .probe() and .probe_new() have the same semantic, they can be defined as members of an anonymous union to save some memory and simplify the core code a bit.

As notifier callbacks, when (un)registering I2C adapters created or destroyed after i2c_dev_init(), 2. As bus iterator callbacks, for registering already existing adapters from i2c_dev_init(), and for cleanup. Unfortunately both use cases expect different return values: the former expects NOTIFY_* return codes, while the latter expects zero or error codes, and aborts in case of error. Hence in case 2, as soon as i2cdev_{at,de}tach_adapter() returns (non-zero) NOTIFY_OK, the bus iterator aborts. This causes (a) only the first already existing adapter to be registered, leading to missing /dev/i2c-* entries, and (b) a failure to unregister all but the first I2C adapter during cleanup. Fix this by introducing separate callbacks for the bus iterator, wrapping the notifier functions, and always returning succes. Any errors inside these callback functions are unlikely to happen, and are fatal anyway.

Because only using cpumask_clear_cpu without local_flush_tlb_all couldn't guarantee CPU's TLB entries were fresh. Then set_mm_asid would cause the user space application to get a stale value by stale TLB entry, but set_mm_noasid is okay. Here is the symptom of the bug: unhandled signal 11 code 0x1 (coredump) 0x0000003fd6d22524 <+4>: auipc s0,0x70 0x0000003fd6d22528 <+8>: ld s0,-148(s0) # 0x3fd6d92490 => 0x0000003fd6d2252c <+12>: ld a5,0(s0) (gdb) i r s0 s0 0x8082ed1cc3198b21 0x8082ed1cc3198b21 (gdb) x /2x 0x3fd6d92490 0x3fd6d92490: 0xd80ac8a8 0x0000003f The core dump file shows that register s0 is wrong, but the value in memory is correct. Because 'ld s0, -148(s0)' used a stale mapping entry in TLB and got a wrong result from an incorrect physical address. When the task ran on CPU0, which loaded/speculative-loaded the value of address(0x3fd6d92490), then the first version of the mapping entry was PTWed into CPU0's TLB. When the task switched from CPU0 to CPU1 (No local_tlb_flush_all here by asid), it happened to write a value on the address (0x3fd6d92490). It caused do_page_fault -> wp_page_copy -> ptep_clear_flush -> ptep_get_and_clear & flush_tlb_page. The flush_tlb_page used mm_cpumask(mm) to determine which CPUs need TLB flush, but CPU0 had cleared the CPU0's mm_cpumask in the previous switch_mm. So we only flushed the CPU1 TLB and set the second version mapping of the PTE. When the task switched from CPU1 to CPU0 again, CPU0 still used a stale TLB mapping entry which contained a wrong target physical address. It raised a bug when the task happened to read that value. CPU0 CPU1 - switch 'task' in - read addr (Fill stale mapping entry into TLB) - switch 'task' out (no tlb_flush) - switch 'task' in (no tlb_flush) - write addr cause pagefault do_page_fault() (change to new addr mapping) wp_page_copy() ptep_clear_flush() ptep_get_and_clear() & flush_tlb_page() write new value into addr - switch 'task' out (no tlb_flush) - switch 'task' in (no tlb_flush) - read addr again (Use stale mapping entry in TLB) get wrong value from old phyical addr, BUG! The solution is to keep all CPUs' footmarks of cpumask(mm) in switch_mm, which could guarantee to invalidate all stale TLB entries during TLB flush.

Particularly, if of_property_match_string() returned -EINVAL, that return code was passed as the index to of_parse_phandle(), which then detected it as invalid and returned NULL. That led to an return code of -ENOENT.

Even though the arm64 version of the EFI stub may relocate the kernel before executing it, it always did so after disabling the MMU, and so we were always in line with what the NX compat flag conveys, we just never bothered to set it.

It resulted in a frozen screen even if something is redrawn there after the close. The breakage is because the patch was made under a wrong assumption of a single open; in the current code, fb_deferred_io_release() cleans up the page mapping of the pageref list and it calls cancel_delayed_work_sync() unconditionally, where both are no correct behavior for multiple opens. This patch adds a refcount for the opens of the device, and applies the cleanup only when all files get closed. As both fb_deferred_io_open() and _close() are called always in the fb_info lock (mutex), it's safe to use the normal int for the refcounting. Also, a useless BUG_ON() is dropped.

The "default y" was added in 2010 by commit df486a25900f ("NFS: Fix the selection of security flavours in Kconfig"). However, svc_gss_principal was removed in 2012 by commit 03a4e1f6ddf2 ("nfsd4: move principal name into svc_cred"), so the 2010 fix is no longer necessary. We can safely change the NFS_V4 and NFSD_V4 dependencies back to RPCSEC_GSS_KRB5 to get the nicer v6.2 behavior back. Selecting KRB5 symbolically represents the true requirement here: that all spec-compliant NFSv4 implementations must have Kerberos available to use.

Note that the above is actually a lockdep false positive, as the chain involves two separate sockets. A different per-socket lockdep key will address the issue, but such a change will be quite invasive. Instead, we can simply stop earlier the socket error handling for orphaned or unaccepted subflows, breaking the critical lockdep chain. Error handling in such a scenario is a no-op.

It needs to be synchronized on each update, and expands badly to a setup where different timers can have different offsets, or have composite offsets (as with NV). So let's start by replacing the use of the CNTVOFF_EL2 shadow register (which we want to reclaim for NV anyway), and make the virtual timer carry a pointer to a VM-wide offset. This simplifies the code significantly. It also addresses two terrible bugs: - The use of CNTVOFF_EL2 leads to some nice offset corruption when the sysreg gets reset, as reported by Joey. - The kvm mutex is taken from a vcpu ioctl, which goes against the locking rules...

We have a number of users that take the previous return value of one of the bit scanning functions and subtract one to keep it in "range". But since the scanning functions end up returning up to 'small_cpumask_bits' instead of the tighter 'nr_cpumask_bits', the range really needs to be using that widened form. [ This "previous-1" behavior is also the reason we have all those comments about /* -1 is a legal arg here. */ and separate checks for that being ok. So we could have just made "small_cpumask_bits-1" be a similar special "don't check this" value. Tetsuo Handa even suggested a patch that only does that for cpumask_next(), since that seems to be the only actual case that triggers, but that all makes it even _more_ magical and special. So just relax the check ] One example of this kind of pattern being the 'c_start()' function in arch/x86/kernel/cpu/proc.c, but also duplicated in various forms on other architectures.

These errors will be processed during late init once the MCE subsystem is fully set up. A number of sysfs updates call mce_restart() which goes through a subset of the CPU init flow. This includes polling MCA banks and logging any errors found. Since the same function is used as boot-time polling, errors will be queued. However, the system is now past late init, so the errors will remain queued until another error is found and the workqueue is triggered. Call mce_schedule_work() at the end of mce_restart() so that queued errors are processed.

This issue has been fixed in newer versions of the fTPM firmware, but it's up to system designers to decide whether to distribute it. This issue has existed for a while, but is more prevalent starting with kernel 6.1 because commit b006c439d58db ("hwrng: core - start hwrng kthread also for untrusted sources") started to use the fTPM for hwrng by default. However, all uses of /dev/hwrng result in unacceptable stuttering. So, simply disable registration of the defective hwrng when detecting these faulty fTPM versions. As this is caused by faulty firmware, it is plausible that such a problem could also be reproduced by other TPM interactions, but this hasn't been shown by any user's testing or reports. It is hypothesized to be triggered more frequently by the use of the RNG because userspace software will fetch random numbers regularly. Intentionally continue to register other TPM functionality so that users that rely upon PCR measurements or any storage of data will still have access to it. If it's found later that another TPM functionality is exacerbating this problem a module parameter it can be turned off entirely and a module parameter can be introduced to allow users who rely upon fTPM functionality to turn it on even though this problem is present.

However, the IOMMU domain referred to by `v->domain` is freed in vhost_vdpa_free_domain() before vhost_vdpa_cleanup() in vhost_vdpa_release() which results in NULL pointer de-reference. Accordingly, moving the call to vhost_vdpa_free_domain() in vhost_vdpa_cleanup() would makes sense. This will also help detaching the dma device in error handling of vhost_vdpa_alloc_domain().

In particular on an SR-IOV device VFs may be removed and later re-added. In commit a50297cf8235 ("s390/pci: separate zbus creation from scanning") it was missed however that struct pci_bus and struct zpci_bus's resource list retained a reference to the PCI functions MMIO resources even though those resources are released and freed on hot-unplug. These stale resources may subsequently be claimed when the PCI function re-appears resulting in use-after-free. One idea of fixing this use-after-free in s390 specific code that was investigated was to simply keep resources around from the moment a PCI function first appeared until the whole virtual PCI bus created for a multi-function device disappears. The problem with this however is that due to the requirement of artificial MMIO addreesses (address cookies) extra logic is then needed to keep the address cookies compatible on re-plug. At the same time the MMIO resources semantically belong to the PCI function so tying their lifecycle to the function seems more logical. Instead a simpler approach is to remove the resources of an individually hot-unplugged PCI function from the PCI bus's resource list while keeping the resources of other PCI functions on the PCI bus untouched. This is done by introducing pci_bus_remove_resource() to remove an individual resource. Similarly the resource also needs to be removed from the struct zpci_bus's resource list. It turns out however, that there is really no need to add the MMIO resources to the struct zpci_bus's resource list at all and instead we can simply use the zpci_bar_struct's resource pointer directly.

Root cause analysis pointed at an issue in barrier processing code -- a race among perf open / close replacing active barriers with perf requests on kernel context and concurrent barrier preallocate / acquire operations performed during user context first pin / last unpin. When adding a request to a composite tracker, we try to reuse an existing fence tracker, already allocated and registered with that composite. The tracker we obtain may already track another fence, may be an idle barrier, or an active barrier. If the tracker we get occurs a non-idle barrier then we try to delete that barrier from a list of barrier tasks it belongs to. However, while doing that we don't respect return value from a function that performs the barrier deletion. Should the deletion ever fail, we would end up reusing the tracker still registered as a barrier task. Since the same structure field is reused with both fence callback lists and barrier tasks list, list corruptions would likely occur. Barriers are now deleted from a barrier tasks list by temporarily removing the list content, traversing that content with skip over the node to be deleted, then populating the list back with the modified content. Should that intentionally racy concurrent deletion attempts be not serialized, one or more of those may fail because of the list being temporary empty. Related code that ignores the results of barrier deletion was initially introduced in v5.4 by commit d8af05ff38ae ("drm/i915: Allow sharing the idle-barrier from other kernel requests"). However, all users of the barrier deletion routine were apparently serialized at that time, then the issue didn't exhibit itself. Results of git bisect with help of a newly developed igt@gem_barrier_race@remote-request IGT test indicate that list corruptions might start to appear after commit 311770173fac ("drm/i915/gt: Schedule request retirement when timeline idles"), introduced in v5.5. Respect results of barrier deletion attempts -- mark the barrier as idle only if successfully deleted from the list. Then, before proceeding with setting our fence as the one currently tracked, make sure that the tracker we've got is not a non-idle barrier. If that check fails then don't use that tracker but go back and try to acquire a new, usable one. v3: use unlikely() to document what outcome we expect (Andi), - fix bad grammar in commit description. v2: no code changes, - blame commit 311770173fac ("drm/i915/gt: Schedule request retirement when timeline idles"), v5.5, not commit d8af05ff38ae ("drm/i915: Allow sharing the idle-barrier from other kernel requests"), v5.4, - reword commit description.

Therefore, the host is permitted and encouraged to throttle such guest requests. Add the capability to handle the case when the hypervisor throttles excessive numbers of requests issued by the guest. Otherwise, the VM platform communication key will be disabled, preventing the guest from attesting itself. Realistically speaking, a well-behaved guest should not even care about throttling. During its lifetime, it would end up issuing a handful of requests which the hardware can easily handle. This is more to address the case of a malicious guest. Such guest should get throttled and if its VMPCK gets disabled, then that's its own wrongdoing and perhaps that guest even deserves it. To the implementation: the hypervisor signals with SNP_GUEST_REQ_ERR_BUSY that the guest requests should be throttled. That error code is returned in the upper 32-bit half of exitinfo2 and this is part of the GHCB spec v2. So the guest is given a throttling period of 1 minute in which it retries the request every 2 seconds. This is a good default but if it turns out to not pan out in practice, it can be tweaked later. For safety, since the encryption algorithm in GHCBv2 is AES_GCM, control must remain in the kernel to complete the request with the current sequence number. Returning without finishing the request allows the guest to make another request but with different message contents. This is IV reuse, and breaks cryptographic protections.

This can result in a negative slot number if the unsigned int value is very large. A negative number means that the slot is empty, but setting a negative slot number this way will not remove the device from the array. I don't think this is a serious problem, but it could cause confusion and it is best to fix it.

However, this means that struct screen_info may not have been populated yet by the time the earlycon probe takes place, and this results in a non-functional early console. So let's probe again right after parsing the config tables and populating struct screen_info. Note that this means that earlycon output starts a bit later than before, and so it may fail to capture issues that occur while doing the early EFI initialization.

It became possible because we now specify all GSI register offsets explicitly for every version of IPA. Unfortunately, a large number of register offsets were *not* updated as they should have been in that commit. For IPA v4.5+, the offset for every GSI register *except* the two inter-EE interrupt masking registers were supposed to have been reduced by 0xd000.

The bug is benign as bit 9 is reserved and never set by KVM, i.e. KVM is just clearing bits that are guaranteed to be zero. Note, as of this writing, APM "Rev. 3.39-October 2022" incorrectly states that bits 11:8 are reserved in Table B-1. VMCB Layout, Control Area. I.e. that table wasn't updated when x2AVIC support was added. Opportunistically fix the comment for the max AVIC ID to align with the code, and clean up comment formatting too.

The AVIC GATag is programmed into the AMD IOMMU IRTE to provide a reference back to KVM in case the IOMMU cannot inject an interrupt into a non-running vCPU. In such a case, the IOMMU notifies software by creating a GALog entry with the corresponded GATag, and KVM then uses the GATag to find the correct VM+vCPU to kick. Dropping bit 8 from the GATag results in kicking the wrong vCPU when targeting vCPUs with x2APIC ID > 255.

Now that lockdep is learning to catch such things, make sure that code path is exercised by the selftest.

Preserve only some user-defined settings in user_overdrive_table if they're set. Copy restored user_overdrive_table into od_table to get correct values. On cold boot, BTC was triggered and GfxVfCurve was calibrated. We got VfCurve settings (a). On resuming back, BTC will be triggered again and GfxVfCurve will be recalibrated. VfCurve settings (b) got may be different from those of cold boot. So if we reuse those VfCurve settings (a) got on cold boot on suspend, we can run into discrepencies.

We might have some cases of FW issues that prevents this mode to working properly though, ending-up in a failed probe. An example below, observed in the Steam Deck: [...] [drm] failed to load ucode VCN0_RAM(0x3A) [drm] psp gfx command LOAD_IP_FW(0x6) failed and response status is (0xFFFF0000) amdgpu 0000:04:00.0: [drm:amdgpu_ring_test_helper [amdgpu]] *ERROR* ring vcn_dec_0 test failed (-110) [drm:amdgpu_device_init.cold [amdgpu]] *ERROR* hw_init of IP block failed -110 amdgpu 0000:04:00.0: amdgpu: amdgpu_device_ip_init failed amdgpu 0000:04:00.0: amdgpu: Fatal error during GPU init [...] Disabling the VCN block circumvents this, but it's a very invasive workaround that turns off the entire feature. So, let's add a quirk on VCN loading that checks for known problematic BIOSes on Vangogh, so we can proactively disable the indirect SRAM mode and allow the HW proper probe and VCN IP block to work fine.

However while doing that it also started using list_add_tail() instead of list_add() used previously thus effectively submitting requests in reverse order. Also when forming a rq_list with remaining requests (in case two or more devices are used), we effectively reverse the ordering of the plug list for each device we process. Submitting requests in reverse order has negative impact on performance for rotational disks (when BFQ is not in use). We observe 10-25% regression in random 4k write throughput, as well as ~20% regression in MariaDB OLTP benchmark on rotational storage on btrfs filesystem. Fix the problem by preserving ordering of the plug list when inserting requests into the queuelist as well as by appending to requeue_list instead of prepending to it.

Since inodes that are in-use by the Landlock LSM don't get evicted until security_sb_delete(), this means that fscrypt_destroy_keyring() must be called *after* security_sb_delete(). This fixes a WARN_ON followed by a NULL dereference, only possible if Landlock was being used on encrypted files.

After this commit, nfs_readpages() is converted to nfs_readahead(), which now uses the new mm interface readahead_page(). The new interface requires callers to call task_io_account_read() themselves. In addition, to nfs_readahead() task_io_account_read() should also be called from nfs_read_folio().

This includes random binary data in the device name, which makes its way into the ftrace output and ends up crashing sleepgraph because it expects the ftrace output to be ASCII only. For example: "HID-SENSOR-INT-020b?.39.auto" ends up in ftrace instead of "HID-SENSOR-INT-020b.39.auto". It causes this crash in sleepgraph: File "/usr/bin/sleepgraph", line 5579, in executeSuspend for line in fp: File "/usr/lib/python3.10/codecs.py", line 322, in decode (result, consumed) = self._buffer_decode(data, self.errors, final) UnicodeDecodeError: 'utf-8' codec can't decode byte 0xff in position 1568: invalid start byte The issue is present in 6.3-rc1 and is described in full here: https://bugzilla.kernel.org/show_bug.cgi?id=217169 A separate fix has been submitted to have this issue repaired, but it has also exposed a larger bug in sleepgraph, since nothing should make sleepgraph crash. Sleepgraph needs to be able to handle binary data showing up in ftrace gracefully. Modify the ftrace processing code to treat it as potentially binary and to filter out binary data and leave just the ASCII.

And this warning was only triggered if lockdep was enabled. If the tracepoint was never enabled with lockdep, the bug would not be caught. To handle this, the above sequence was done when lockdep was enabled regardless if the tracepoint was enabled or not (although the always enabled code really didn't do anything, it would still trigger a warning). But a lot has changed since that lockdep code was added. One is, that sequence no longer triggers any warning. Another is, the tracepoint when enabled doesn't even do that sequence anymore. The main check we care about today is whether RCU is "watching" or not. So if lockdep is enabled, always check if rcu_is_watching() which will trigger a warning if it is not (tracepoints require RCU to be watching). Note, that old sequence did add a bit of overhead when lockdep was enabled, and with the latest kernel updates, would cause the system to slow down enough to trigger kernel "stalled" warnings.

Make DFS root sessions have same lifetime as DFS tcons so we can avoid the use-after-free bug is DFS cache refresher and other places that require IPCs to get new DFS referrals on.

It is indeed the allocation size of a cpumask. But the code also assumes that the whole allocation is initialized without actually doing so itself. That's wrong, because we might have fixed-size allocations (making copying and clearing more efficient), but not all of it is then necessarily used if 'nr_cpu_ids' is smaller. Having checked other users of 'cpumask_size()', they all seem to be ok, either using it purely for the allocation size, or explicitly zeroing the cpumask before using the size in bytes to copy it. See for example the ublk_ctrl_get_queue_affinity() function that uses the proper 'zalloc_cpumask_var()' to make sure that the whole mask is cleared, whether the storage is on the stack or if it was an external allocation. Fix this by just zeroing the allocation before using it. Do the same for the compat version of sched_getaffinity(), which had the same logic. Also, for consistency, make sched_getaffinity() use 'cpumask_bits()' to access the bits. For a cpumask_var_t, it ends up being a pointer to the same data either way, but it's just a good idea to treat it like you would a 'cpumask_t'. The compat case already did that.

With this, debian/control lists which binary packages will be produced. Previously, ARCH=um listed linux-libc-dev in debian/control, but it was not generated because each of mkdebian and builddeb independently maintained the if-conditionals. Another motivation is to allow scripts/package/builddeb to get the package name (linux-image-*, etc.) dynamically from debian/control. This will also allow the BuildProfile to control the generation of the binary packages.

To enforce this, when an interface enters a bond, we unplug the auxiliary device that supports RDMA functionality. This unplug currently happens in the context of handling the netdev bonding event. This event is sent to the ice driver under RTNL context. This is causing a deadlock where the RDMA driver is waiting for the RTNL lock to complete the removal. Defer the unplugging/re-plugging of the auxiliary device to the service task so that it is not performed under the RTNL lock context.

Paul Holzinger reported [0] that commit 5456262d2baa ("net: Fix incorrect address comparison when searching for a bind2 bucket") introduced a bind() regression. Paul also gave a nice repro that calls two types of bind() on the same port, both of which now succeed, but the second call should fail: bind(fd1, ::, port) + bind(fd2, 127.0.0.1, port) The cited commit added address family tests in three functions to fix the uninit-value KMSAN report. [1] However, the test added to inet_bind2_bucket_match_addr_any() removed a necessary conflict check; the dual-stack wildcard address no longer conflicts with an IPv4 non-wildcard address. If tb->family is AF_INET6 and sk->sk_family is AF_INET in inet_bind2_bucket_match_addr_any(), we still need to check if tb has the dual-stack wildcard address. Note that the IPv4 wildcard address does not conflict with IPv6 non-wildcard addresses.

By default, the limit is 96 bytes. There are several cases where this parsing depth is not enough and there is a need to increase it. For example, timestamping of PTP packets and a FIB multipath hash policy that requires hashing on inner fields. The driver therefore maintains a reference count that reflects the number of consumers that require an increased parsing depth. During reload_down() the parsing depth reference count does not necessarily drop to zero, but the parsing depth itself is restored to the default during reload_up() when the firmware is reset. It is therefore possible to end up in situations where the driver thinks that the parsing depth was increased (reference count is non-zero), when it is not. Fix by making sure that all the consumers that increase the parsing depth reference count also decrease it during reload_down(). Specifically, make sure that when the routing code is de-initialized it drops the reference count if it was increased because of a FIB multipath hash policy that requires hashing on inner fields. Add a warning if the reference count is not zero after the driver was de-initialized and explicitly reset it to zero during initialization for good measures.

This is incorrect, as it ignores that both VM_WRITE and VM_EXEC imply read on powerpc, as defined in protection_map[]. This causes mappings containing VM_WRITE or VM_EXEC without VM_READ to misreport the cause of page faults, since the MMU is still allowing reads. Correct this by restoring the original vma_is_accessible() check for PROT_NONE mappings, and adding a separate check for Radix PROT_EXEC-only mappings.

However if the request times out the core expects to find the opcode in the start of the request, which we override. In order to prevent that, without sacrificing additional 24 bytes per request, we just use the tail of the command pdu space instead (last 24 bytes from the 72 bytes command pdu). That should make the command opcode always available, and we get away from allocating more space. If in the future we would need the last 24 bytes of the nvme command available we would need to allocate a dedicated space for it in the request, but until then we can avoid doing so.

This results a read on a range which has no chunk mapping.

It counts not only active block groups but also full ones which are previously active but now inactive. That confusion results in a bug not counting the full BGs into active_total_bytes on mount time. For a background, there are three kinds of block groups in terms of activation. 1. Block groups never activated 2. Block groups currently active 3. Block groups previously active and currently inactive (due to fully written or zone finish) What we really wanted to exclude from "total_bytes" is the total size of BGs #1. They seem empty and allocatable but since they are not activated, we cannot rely on them to do the space reservation. And, since BGs #1 never get activated, they should have no "used", "reserved" and "pinned" bytes. OTOH, BGs #3 can be counted in the "total", since they are already full we cannot allocate from them anyway. For them, "total_bytes == used + reserved + pinned + zone_unusable" should hold. Tracking #2 and #3 as "active_total_bytes" (current implementation) is confusing. And, tracking #1 and subtract that properly from "total_bytes" every time you need space reservation is cumbersome. Instead, we can count the whole region of a newly allocated block group as zone_unusable. Then, once that block group is activated, release [0 .. zone_capacity] from the zone_unusable counters. With this, we can eliminate the confusing ->active_total_bytes and the code will be common among regular and the zoned mode. Also, no additional counter is needed with this approach.

For PAGE_SIZE=4K, MTU shouldn't exceed 3498. Features that contradict with XDP such HW-LRO and HW-GRO are enforced by the driver in advance, during XSK params validation, except for MTU, which was not enforced before this patch. This has been spotted during test scenario described below: Attaching xdpsock program (PAGE_SIZE=4K), with MTU < 3498, detaching XDP program, changing the MTU to arbitrary value in the range [3499, 3754], attaching XDP program again, which ended up with failure since MTU is > 3498. This commit lowers the XSK MTU limitation to be aligned with XDP MTU limitation, since XSK socket is meaningless without XDP program.

My intention was to create source packages without cleaning the source tree, without relying on git. Linus strongly objected to it, and suggested using 'git archive' instead. [1] [2] [3] This commit goes in that direction - Remove scripts/list-gitignored.c and rewrites Makefiles and scripts to use 'git archive' for building Debian and RPM source packages. It also makes 'make perf-tar*-src-pkg' use 'git archive' again. Going forward, building source packages is only possible in a git-managed tree. Building binary packages does not require git.

The reason is that we try to drop excessive references with folio_put_refs(), but pages were acquired with pin_user_pages(), which has extra accounting and so should be put down with matching unpin_user_pages() or at least gup_put_folio(). As a fix unpin_user_pages() all but first page instead, and let's figure out a better API after.

For instance, tc qdisc replace ... taprio num_tc 4 ... sched-entry S 0x01 100000 # slot#1 sched-entry S 0x03 100000 # slot#2 sched-entry S 0x04 100000 # slot#3 sched-entry S 0x08 200000 # slot#4 flags 0x02 # hardware offload Here the queue#0 (the first queue) is on at the slot#1 and #2, and off at the slot#3 and #4. Under the current logic, when the slot#4 is examined, validate_schedule() returns *false* since the enablement count for the queue#0 is two and it is already off at the previous slot (i.e. #3). But this definition is truely correct. Let's fix the logic to enforce a strict validation for consecutively-opened slots.

But it would be good if the logic went through, for example if the DSA master really depends on an MTU adjustment to accept DSA-tagged frames. To make the code pass through the check, we need to adjust mtu_limit for the overhead as well, if the minimum restriction was caused by the DSA user port's MTU (dev->max_mtu). A DSA user port MTU and a DSA master MTU are always offset by the protocol overhead. Currently no drivers return 1500 .port_max_mtu(), but this is only temporary and a bug in itself - mv88e6xxx should have done that, but since commit b9c587fed61c ("dsa: mv88e6xxx: Include tagger overhead when setting MTU for DSA and CPU ports") it no longer does.

Here, the chip->info->ops->port_set_jumbo_size() method will be present. - MTU configuration is global to the switch. Here, the chip->info->ops->set_max_frame_size() method will be present. - We don't know how to change the MTU. Here, none of the above methods will be present. Switch families MV88E6165, MV88E6191, MV88E6220, MV88E6250 and MV88E6290 fall in category 3. The blamed commit has adjusted the MTU for all 3 categories by EDSA_HLEN (8 bytes), resulting in a new maximum MTU of 1492 being reported by the driver for these switches. I don't have the hardware to test, but I do have a MV88E6390 switch on which I can simulate this by commenting out its .port_set_jumbo_size definition from mv88e6390_ops. The result is this set of messages at probe time: mv88e6085 d0032004.mdio-mii:10: nonfatal error -34 setting MTU to 1500 on port 1 mv88e6085 d0032004.mdio-mii:10: nonfatal error -34 setting MTU to 1500 on port 2 mv88e6085 d0032004.mdio-mii:10: nonfatal error -34 setting MTU to 1500 on port 3 mv88e6085 d0032004.mdio-mii:10: nonfatal error -34 setting MTU to 1500 on port 4 mv88e6085 d0032004.mdio-mii:10: nonfatal error -34 setting MTU to 1500 on port 5 mv88e6085 d0032004.mdio-mii:10: nonfatal error -34 setting MTU to 1500 on port 6 mv88e6085 d0032004.mdio-mii:10: nonfatal error -34 setting MTU to 1500 on port 7 mv88e6085 d0032004.mdio-mii:10: nonfatal error -34 setting MTU to 1500 on port 8 It is highly implausible that there exist Ethernet switches which don't support the standard MTU of 1500 octets, and this is what the DSA framework says as well - the error comes from dsa_slave_create() -> dsa_slave_change_mtu(slave_dev, ETH_DATA_LEN). But the error messages are alarming, and it would be good to suppress them. As a consequence of this unlikeliness, we reimplement mv88e6xxx_get_max_mtu() and mv88e6xxx_change_mtu() on switches from the 3rd category as follows: the maximum supported MTU is 1500, and any request to set the MTU to a value larger than that fails in dev_validate_mtu().

This is caused by the i2c-mxs driver using DMA transfers even for messages without the I2C_M_DMA_SAFE flag, and the aforementioned commit enabling vmapped stacks. As the MXS I2C controller requires DMA for reads of >4 bytes, DMA can't be disabled, so the issue is fixed by using i2c_get_dma_safe_msg_buf() to create a bounce buffer when needed.

This field is initialized using the 'fc_table' field in the route configuration structure, which is not set when adding a route via IOCTL. The above can result in user space being able to install two identical routes that only differ in the table ID field of their associated FIB info. Fix by initializing the table ID field in the route configuration structure in the IOCTL path. Before the fix: # ip route add default via 192.0.2.2 # route add default gw 192.0.2.2 # ip -4 r show default # default via 192.0.2.2 dev dummy10 # default via 192.0.2.2 dev dummy10 After the fix: # ip route add default via 192.0.2.2 # route add default gw 192.0.2.2 SIOCADDRT: File exists # ip -4 r show default default via 192.0.2.2 dev dummy10 Audited the code paths to ensure there are no other paths that do not properly initialize the route configuration structure when installing a route.

The XDP_ABORTED handler in turn calls the bpf_warn_invalid_xdp_action() tracepoint. However, the function also jumps into the XDP_PASS helper if no XDP program is loaded on the device, which means the XDP_ABORTED handler can be run with a NULL program pointer. This results in a NULL pointer deref because the tracepoint dereferences the 'prog' pointer passed to it. This situation can happen in multiple ways: - If a packet arrives between the removal of the program from the interface and the static_branch_dec() in aq_xdp_setup() - If there are multiple devices using the same driver in the system and one of them has an XDP program loaded and the other does not. Fix this by refactoring the aq_xdp_run_prog() function to remove the 'goto pass' handling if there is no XDP program loaded. Instead, factor out the skb building in a separate small helper function.

When looking at the conflict, I noticed it is in fact the v1 [3] that has been applied in -net and the v2 [4] in net-next. Maybe the v1 was applied by accident. As mentioned by Jakub Kicinski [5], the new condition makes more sense before the net_ratelimit(), not to update net_ratelimit's state which is unnecessary if we're not going to print either way. Here, this modification applies the v2 but in -net.

The trouble is that, when compared to ksz_write8(), ksz_pwrite8() also adjusts the register offset with the port base address. So in reality, ksz_pwrite8(offset=0x56) accesses register 0x56 + 0x50 = 0xa6, which in this switch appears to be unmapped, and the RGMII delay configuration on the CPU port does nothing. So if the switch wasn't fine with the RGMII delay configuration done through pin strapping and relied on Linux to apply a different one in order to pass traffic, this is now broken. Using the offset translation logic imposed by ksz_pwrite8(), the correct value for regs[P_XMII_CTRL_1] should have been 0x6 on ksz8795_regs[], in order to really end up accessing register 0x56. Static code analysis shows that, despite there being multiple other accesses to regs[P_XMII_CTRL_1] in this driver, the only code path that is applicable to ksz8795_regs[] and ksz8_dev_ops is ksz_set_xmii(). Therefore, the problem is isolated to RGMII delays. In its current form, ksz8795_regs[] contains the same value for P_XMII_CTRL_0 and for P_XMII_CTRL_1, and this raises valid suspicions that writes made by the driver to regs[P_XMII_CTRL_0] might overwrite writes made to regs[P_XMII_CTRL_1] or vice versa. Again, static analysis shows that the only accesses to P_XMII_CTRL_0 from the driver are made from code paths which are not reachable with ksz8_dev_ops. So the accesses made by ksz_set_xmii() are safe for this switch family.

It's possible however to get a splice result that only has a partial page at the end, if (e.g.) the filesystem hands back a short read that doesn't cover the whole page. nfsd_splice_actor will plop the partial page into its rq_pages array and return. Then later, when nfsd_splice_actor is called again, the remainder of the page may end up being filled out. At this point, nfsd_splice_actor will put the page into the array _again_ corrupting the reply. If this is done enough times, rq_next_page will overrun the array and corrupt the trailing fields -- the rq_respages and rq_next_page pointers themselves. If we've already added the page to the array in the last pass, don't add it to the array a second time when dealing with a splice continuation. This was originally handled properly in nfsd_splice_actor, but commit 91e23b1c3982 ("NFSD: Clean up nfsd_splice_actor()") removed the check for it.

But sysfb_apply_efi_quirks() modifies the global screen_info struct which [sysfb_]parse_mode() parses, so doing it later is too late. This has broken all DMI based quirks for correcting wrong firmware efifb settings when simpledrm is used. To fix this move the sysfb_apply_efi_quirks() call back to its old place and split the new setup of the efifb_fwnode (which requires the platform_device) into its own function and call that at the place of the moved sysfb_apply_efi_quirks(pd) calls.

Now, in practice this doesn't likely matter, because the code will always find the entry it looks for, and will thus return early and never hit that last extra iteration. But it turns out that clang will unroll the loop fully, because it has only two iterations (well, three due to the off-by-one bug), and then clang will end up just giving up in the middle of the loop unrolling when it notices that the code walks past the end of the array. And that made 'objtool' very unhappy indeed, because the generated code just falls off the edge of the universe, and ends up falling through to the next function, causing this warning: drivers/media/i2c/m5mols/m5mols.o: warning: objtool: m5mols_set_fmt() falls through to next function m5mols_get_frame_desc() Fix the loop ending condition.

But it used to be possible due to the bug, now fixed, where fscrypt_destroy_keyring() was called before security_sb_delete(). To be consistent with how fscrypt_destroy_keyring() uses WARN_ON for the same issue, WARN and leak the fscrypt_master_key if the keyring is NULL instead of dereferencing the NULL pointer. This is a robustness improvement, not a fix.

This breaks DMA when the host DMA address width is <=32it but the device is >32bit. Right now the driver may decide to use a 2nd DMA descriptor for another buffer (happens in case of TSO xmit) assuming that 32bit addressing is used due to platform configuration but the device will still use both descriptor addresses as one address. This can be observed with the Intel EHL platform driver that sets 32bit for addr64 but the MAC reports 40bit. The TX queue gets stuck in case of TCP with iptables NAT configuration on TSO packets. The logic should be like this: Whatever we do on the host side (memory allocation GFP flags) should happen with the host DMA width, whenever we decide how to set addresses on the device registers we must use the device DMA address width. This patch renames the platform address width field from addr64 (term used in device datasheet) to host_addr and uses this value exclusively for host side operations while all chip operations consider the device DMA width as read from the device register.

What makes SFF modules different from SFPs is they typically have an inverted LOS, which uncovered this issue. When we read the hardware state, we mask it with state_hw_mask so we ignore anything we're not interested in. However, we don't re-read when state_hw_mask changes, leading to sfp->state being stale. Arrange for a software poll of the module state after we have parsed the EEPROM in sfp_sm_mod_probe() and updated state_*_mask. This will generate any necessary events for signal changes for the state machine as well as updating sfp->state.

Due to an off-by-one error, the last element in the array was not initialized, causing it to be set to zero, which in turn lead to fans being configured with a 0% duty cycle in maximum cooling state. Since commit 332fdf951df8 ("mlxsw: thermal: Fix out-of-bounds memory accesses") the contents of the array are static. Therefore, instead of fixing the initialization of the array, simply remove it and adjust thermal_cooling_device_ops::set_cur_state() so that the configured duty cycle is never set below 20%.

Wong" Date: Wed, 15 Mar 2023 17:30:33 -0700 Subject: [PATCH 792/976] xfs: walk all AGs if TRYLOCK passed to xfs_alloc_vextent_iterate_ags Callers of xfs_alloc_vextent_iterate_ags that pass in the TRYLOCK flag want us to perform a non-blocking scan of the AGs for free space. There are no ordering constraints for non-blocking AGF lock acquisition, so the scan can freely start over at AG 0 even when minimum_agno > 0. This manifests fairly reliably on xfs/294 on 6.3-rc2 with the parent pointer patchset applied and the realtime volume enabled. I observed the following sequence as part of an xfs_dir_createname call: 0. Fragment the free space, then allocate nearly all the free space in all AGs except AG 0. 1. Create a directory in AG 2 and let it grow for a while. 2. Try to allocate 2 blocks to expand the dirent part of a directory. The space will be allocated out of AG 0, but the allocation will not be contiguous. This (I think) activates the LOWMODE allocator. 3. The bmapi call decides to convert from extents to bmbt format and tries to allocate 1 block. This allocation request calls xfs_alloc_vextent_start_ag with the inode number, which starts the scan at AG 2. We ignore AG 0 (with all its free space) and instead scrape AG 2 and 3 for more space. We find one block, but this now kicks t_highest_agno to 3. 4. The createname call decides it needs to split the dabtree. It tries to allocate even more space with xfs_alloc_vextent_start_ag, but now we're constrained to AG 3, and we don't find the space. The createname returns ENOSPC and the filesystem shuts down. This change fixes the problem by making the trylock scan wrap around to AG 0 if it doesn't like the AGs that it finds. Since the current transaction itself holds AGF 0, the trylock of AGF 0 will succeed, and we take space from the AG that has plenty. Signed-off-by: Darrick J.

Wong" Date: Thu, 16 Mar 2023 09:31:20 -0700 Subject: [PATCH 794/976] xfs: test dir/attr hash when loading module Back in the 6.2-rc1 days, Eric Whitney reported a fstests regression in ext4 against generic/454. The cause of this test failure was the unfortunate combination of setting an xattr name containing UTF8 encoded emoji, an xattr hash function that accepted a char pointer with no explicit signedness, signed type extension of those chars to an int, and the 6.2 build tools maintainers deciding to mandate -funsigned-char across the board. As a result, the ondisk extended attribute structure written out by 6.1 and 6.2 were not the same. This discrepancy, in fact, had been noticeable if a filesystem with such an xattr were moved between any two architectures that don't employ the same signedness of a raw "char" declaration. The only reason anyone noticed is that x86 gcc defaults to signed, and no such -funsigned-char update was made to e2fsprogs, so e2fsck immediately started reporting data corruption. After a day and a half of discussing how to handle this use case (xattrs with bit 7 set anywhere in the name) without breaking existing users, Linus merged his own patch and didn't tell the maintainer. None of the ext4 developers realized this until AUTOSEL announced that the commit had been backported to stable. In the end, this problem could have been detected much earlier if there had been any useful tests of hash function(s) in use inside ext4 to make sure that they always produce the same outputs given the same inputs. The XFS dirent/xattr name hash takes a uint8_t*, so I don't think it's vulnerable to this problem. However, let's avoid all this drama by adding our own self test to check that the da hash produces the same outputs for a static pile of inputs on various platforms. This enables us to fix any breakage that may result in a controlled fashion. The buffer and test data are identical to the patches submitted to xfsprogs.

The solution was to iterate all possible CPUs for summation via percpu_counter_sum_all(). We recently had a percpu_counter_sum() call in XFS trip over this same race condition and it fired a debug assert because the filesystem was unmounting and the counter *should* be zero just before we destroy it. That was reported here: https://lore.kernel.org/linux-kernel/20230314090649.326642-1-yebin@huaweicloud.com/ likely as a result of running generic/648 which exercises filesystems in the presence of CPU online/offline events. The solution to use percpu_counter_sum_all() is an awful one. We use percpu counters and percpu_counter_sum() for accurate and reliable threshold detection for space management, so a summation race condition during these operations can result in overcommit of available space and that may result in filesystem shutdowns. As percpu_counter_sum_all() iterates all possible CPUs rather than just those online or even those present, the mask can include CPUs that aren't even installed in the machine, or in the case of machines that can hot-plug CPU capable nodes, even have physical sockets present in the machine. Fundamentally, this race condition is caused by the CPU being offlined being removed from the cpu_online_mask before the notifier that cleans up per-cpu state is run. Hence percpu_counter_sum() will not sum the count for a cpu currently being taken offline, regardless of whether the notifier has run or not. This is the root cause of the bug. The percpu counter notifier iterates all the registered counters, locks the counter and moves the percpu count to the global sum. This is serialised against other operations that move the percpu counter to the global sum as well as percpu_counter_sum() operations that sum the percpu counts while holding the counter lock. Hence the notifier is safe to run concurrently with sum operations, and the only thing we actually need to care about is that percpu_counter_sum() iterates dying CPUs. That's trivial to do, and when there are no CPUs dying, it has no addition overhead except for a cpumask_or() operation. This change makes percpu_counter_sum() always do the right thing in the presence of CPU hot unplug events and makes percpu_counter_sum_all() unnecessary. This, in turn, means that filesystems like XFS, ext4, and btrfs don't have to work out when they should use percpu_counter_sum() vs percpu_counter_sum_all() in their space accounting algorithms Signed-off-by: Dave Chinner Reviewed-by: Darrick J.

This will happen if intel_initial_commit() is forced to go through the full modeset calculations for whatever reason. Afterwards the first real commit from userspace will not get forced to the full modeset path, and thus eg. audio state may not get recomputed properly.

As of now it is getting handled while __gt_unpark, __gt_park. But there are various corner cases where forcewakes are taken without __gt_unpark i.e. without sending Busy Mailbox especially during register reads. Forcewakes are taken without busy mailbox leads to GPU HANG. So bringing mailbox calls under forcewake calls are no feasible option as forcewake calls are atomic and mailbox calls are blocking.

Note that only crtc_clock and framedur_ns can actually end up changing here during fastsets. Everything else we touch can only change during full modesets. Technically we should try to do this exactly at the start of vblank, but that would require some kind of double buffering scheme. Let's skip that for now and just update things right after the commit has been submitted to the hardware. This means the information will be properly up to date when the vblank irq handler goes to work. Only if someone ends up querying some vblanky stuff in between the commit and start of vblank may we see a slight discrepancy. Also this same problem really exists for the DRRS downclocking stuff. But as that is supposed to be more or less transparent to the user, and it only drops to low gear after a long delay (1 sec currently) we probably don't have to worry about it. Any time something is actively submitting updates DRRS will remain in high gear and so the timestamping constants will match the hardware state.

This means that when connecting 2 DSA interfaces back to back and sending 1 packet with length 100, the sending interface will report tx_bytes as incrementing by 100, and the receiving interface will report rx_bytes as incrementing by 86. Since accounting for that in scripts is quirky and is something that would be DSA-specific behavior (requiring users to know that they are running on a DSA interface in the first place), the proposal is that we treat it as a bug and fix it. This design bug has always existed in DSA, according to my analysis: commit 91da11f870f0 ("net: Distributed Switch Architecture protocol support") also updates skb->dev->stats.rx_bytes += skb->len after the eth_type_trans() call. Technically, prior to Florian's commit a86d8becc3f0 ("net: dsa: Factor bottom tag receive functions"), each and every vendor-specific tagging protocol driver open-coded the same bug, until the buggy code was consolidated into something resembling what can be seen now. So each and every driver should have its own Fixes: tag, because of their different histories until the convergence point. I'm not going to do that, for the sake of simplicity, but just blame the oldest appearance of buggy code. There are 2 ways to fix the problem. One is the obvious way, and the other is how I ended up doing it. Obvious would have been to move dev_sw_netstats_rx_add() one line above eth_type_trans(), and below skb_push(skb, ETH_HLEN). But DSA processing is not as simple as that. We count the bytes after removing everything DSA-related from the packet, to emulate what the packet's length was, on the wire, when the user port received it. When eth_type_trans() executes, dsa_untag_bridge_pvid() has not run yet, so in case the switch driver requests this behavior - commit 412a1526d067 ("net: dsa: untag the bridge pvid from rx skbs") has the details - the obvious variant of the fix wouldn't have worked, because the positioning there would have also counted the not-yet-stripped VLAN header length, something which is absent from the packet as seen on the wire (there it may be untagged, whereas software will see it as PVID-tagged).

These wakeups are performed by timers and upon entry to idle (also to guest and to user on nohz_full). However the delayed wake-up on kernel exit is actually performed after the thread flags are fetched towards the fast path check for work to do on exit to user. As a result, and if there is no other pending work to do upon that kernel exit, the current task will resume to userspace with TIF_RESCHED set and the pending wake up ignored. Fix this with fetching the thread flags _after_ the delayed RCU-nocb kthread wake-up.

To fix this issue, we can not simply increase the number in the test script because the test bootconfig file becomes too big (>32KB). To fix that, we can use a combination of three alphabets (26^3 = 17576). But with that, we can not express the 8193 (just one exceed from the limitation) because it also exceeds the max size of bootconfig. So, the first 26 nodes will just use one alphabet. With this fix, test-bootconfig.sh passes all tests.

Due to which, a new key request from kernel thread will be served with the cached key if it's present in task struct irrespective of the key validity. The change is to not cache key in task_struct when key requested from kernel thread so that kernel thread gets a valid key on every key request. The problem has been seen with the cifs module doing DNS lookups from a kernel thread and the results getting pinned by being attached to that kernel thread's cache - and thus not something that can be easily got rid of. The cache would ordinarily be cleared by notify-resume, but kernel threads don't do that. This isn't seen with AFS because AFS is doing request_key() within the kernel half of a user thread - which will do notify-resume.

As a result, only first flow director filter can be added, adding next filter leads to NULL pointer dereference attached below. Rx buffer handling and reallocation logic has been optimized, however flow director specific traffic was not accounted for. As a result driver handled those packets incorrectly since new logic was based on ice_rx_ring::first_desc which was not set in this case. Fix this by setting struct ice_rx_ring::first_desc to next_to_clean for flow director received packets.

In iavf_shutdown() the adapter state is changed to __IAVF_REMOVE. In ice_shutdown() the call chain above is executed, which at some point calls iavf_remove(). However iavf_remove() expects the VF to be in one of the states __IAVF_RUNNING, __IAVF_DOWN or __IAVF_INIT_FAILED. If that's not the case it sleeps forever. So if iavf_shutdown() gets invoked before iavf_remove() the system will hang indefinitely because the adapter is already in state __IAVF_REMOVE. Fix this by returning from iavf_remove() if the state is __IAVF_REMOVE, as we already went through iavf_shutdown().

We tried the suggestions from that issue (sysctl net.core.bpf_jit_limit=452534528) which helped to immediately allow containers to be created and probes to execute but after approximately a day the issue returned and the value returned by cat /proc/vmallocinfo | grep bpf_jit | awk '{s+=$2} END {print s}' was steadily increasing. I tested bpf tree to observe bpf_jit_charge_modmem, bpf_jit_uncharge_modmem their sizes passed in as well as bpf_jit_current under tcpdump BPF filter, seccomp BPF and native (e)BPF programs, and the behavior all looks sane and expected, that is nothing "leaking" from an upstream perspective. The bpf_jit_limit knob was originally added in order to avoid a situation where unprivileged applications loading BPF programs (e.g. seccomp BPF policies) consuming all the module memory space via BPF JIT such that loading of kernel modules would be prevented. The default limit was defined back in 2018 and while good enough back then, we are generally seeing far more BPF consumers today. Adjust the limit for the BPF JIT pool from originally 1/4 to now 1/2 of the module memory space to better reflect today's needs and avoid more users running into potentially hard to debug issues.

Therefore, if a PF net device's namespace is different from its parent devlink net namespace, entering switchdev mode can create an illegal situation where all representors sharing the same core device are NOT in the same net namespace.

However, "u32 reg" is not quite a register address, but an enum ocelot_reg, which in itself encodes an enum ocelot_target target in the upper bits, and an index into the ocelot->map[target][] array in the lower bits. So, whereas the previous code comparison between stats_layout[i].offset and last + 1 was correct (because those "offsets" at the time were 32-bit relative addresses), the new code, comparing layout[i].reg to last + 4 is not correct, because the "reg" here is an enum/index, not an actual register address. What we want to compare are indeed register addresses, but to do that, we need to actually go through the same motions as __ocelot_bulk_read_ix() itself.

The driver is aware of multiple counters (enum ocelot_stat), yet not all switches supported by the driver implement all counters. There are 2 statistics layouts: ocelot_stats_layout and ocelot_mm_stats_layout, the latter having 36 counters more than the former. ocelot->stats[] is not a compact array, i.e. there are elements within it which are not going to be populated for ocelot_stats_layout. On the other hand, ocelot->stats[] is easily indexable, for example "tx_octets" for port 3 can be found at ocelot->stats[3 * OCELOT_NUM_STATS + OCELOT_STAT_TX_OCTETS], and that is why we keep it sparse. Regions, as created by ocelot_prepare_stats_regions(), are compact (every element from region->buf will correspond to a counter that is present in this switch's layout) but are not easily indexable. Let's define holes as the ranges of values of enum ocelot_stat for which ocelot_stats_layout doesn't have a "reg" defined. For example, there is a hole between OCELOT_STAT_RX_GREEN_PRIO_7 and OCELOT_STAT_TX_OCTETS which is of 23 elements that are only present on ocelot_mm_stats_layout, and as such, they are also present in enum ocelot_stat. Let's define the left extremity of the hole - the last enum ocelot_stat still defined - as A (in this case OCELOT_STAT_RX_GREEN_PRIO_7) and the right extremity - the first enum ocelot_stat that is defined after a series of undefined ones - as B (in this case OCELOT_STAT_TX_OCTETS). There is a bug in the procedure which transfers stats from region->buf[] to ocelot->stats[]. For each hole in the ocelot_stats_layout, the logic transfers the stats starting with enum ocelot_stat B to ocelot->stats[] index A + 1. So all stats after a hole are saved to a position which is off by B - A + 1 elements. This causes 2 kinds of issues: (a) counters which shouldn't increment increment (b) counters which should increment don't Holes in the ocelot_stat_layout automatically imply the end of a region and the beginning of a new one; however the reverse is not necessarily true. For example, for ocelot_mm_stat_layout, there could be multiple regions (which indicate discontinuities in register addresses) while there is no hole (which indicates discontinuities in enum ocelot_stat values). In the example above, the stats from the second region->buf[] are not transferred to ocelot->stats starting with index "port * OCELOT_NUM_STATS + OCELOT_STAT_TX_OCTETS" as they should, but rather, starting with element "port * OCELOT_NUM_STATS + OCELOT_STAT_RX_GREEN_PRIO_7 + 1". That stats[] array element is not reported to user space for switches that use ocelot_stat_layout, and that is how issue (b) occurs. However, if the length of the second region is larger than the hole, then some stats will start to be transferred to the ocelot->stats[] indices which *are* reported to user space, but those indices contain wrong values (corresponding to unexpected counters). This is how issue (a) occurs. The procedure, as it was introduced in commit d87b1c08f38a ("net: mscc: ocelot: use bulk reads for stats"), was not buggy, because there were no holes in the struct ocelot_stat_layout instances at that time. The problem is that when those holes were introduced, the function was not updated to take them into consideration. To update the procedure, we need to know, for each region, which enum ocelot_stat corresponds to its region->base. We have no way of deducing that based on the contents of struct ocelot_stats_region, so we need to add this information.

When TX_MM_HOLD is defined in enum ocelot_stat but not in struct ocelot_stat_layout ocelot_mm_stats_layout, this creates a hole, which due to the aforementioned bug, makes all counters following TX_MM_HOLD be recorded off by one compared to their correct position. So for example, a non-zero TX_PMAC_OCTETS would be reported as TX_MERGE_FRAGMENTS, TX_PMAC_UNICAST would be reported as TX_PMAC_OCTETS, TX_PMAC_64 would be reported as TX_PMAC_PAUSE, etc etc. This is because the size of the hole (1) is much smaller than the size of the region, so the phenomenon where the stats are off-by-one, rather than lost, prevails. However, the phenomenon where stats are lost can be seen too, for example with DROP_LOCAL, which is at the beginning of its own region (offset 0x000400 vs the previous 0x0002b0 constitutes a discontinuity). This is also reported as off by one and saved to TX_PMAC_1527_MAX, but that counter is not reported to the unstructured "ethtool -S", as opposed to DROP_LOCAL which is (as "drop_local").

Let's show just an information message to notice skipping the bootconfig in that case.

Change the ordering in acpi_processor_driver_init() accordingly to prevent the max_state value from remaining 0 permanently for all ACPI CPU cooling devices due to setting acpi_processor_cpufreq_init too late. [Note that processor_get_max_state() may still return different values at different times after this change, depending on the cpufreq driver registration time, but that issue needs to be addressed separately.] Fixes: a365105c685c("thermal: sysfs: Reuse cdev->max_state") Reported-by: Wang, Quanxian Link: https://lore.kernel.org/linux-pm/53ec1f06f61c984100868926f282647e57ecfb2d.camel@intel.com Signed-off-by: Rafael J.

That callback is now invoked only once, during cooling device registration, to populate the max_state field in the cooling device object, so if its return value changes, it needs to be invoked again and the new return value needs to be stored as max_state. Moreover, the statistics presented in sysfs need to be rearranged in general, because there may not be enough room in them to store data for all of the possible states (in the case when max_state grows). The new function takes care of that (and some other minor things related to it), but some extra locking and lockdep annotations are added in several places too to protect against crashes in the cases when the statistics are not present or when a stale max_state value might be used by sysfs attributes. Note that the actual user of the new function will be added separately. Link: https://lore.kernel.org/linux-pm/53ec1f06f61c984100868926f282647e57ecfb2d.camel@intel.com/ Signed-off-by: Rafael J.

Those two interfaces however have different locks, and there's no single locks that's shared between the tty and the console implementations, hence the driver needs to protect itself against concurrent accesses. Otherwise concurrent calls using the split interfaces are likely to corrupt the ring indexes, leaving the console unusable. Introduce a lock to xencons_info to serialize accesses to the shared ring. This is only required when using the shared memory console, concurrent accesses to the hypercall based console implementation are not an issue. Note the conditional logic in domU_read_console() is slightly modified so the notify_daemon() call can be done outside of the locked region: it's an hypercall and there's no need for it to be done with the lock held.

Currently many drivers also return EOPNOTSUPP when the hint isn't available, which is ambiguous from an API point of view. Instead change drivers to return ENODATA in these cases. There can be natural cases why a driver doesn't provide any hardware info for a specific hint, even on a frame to frame basis (e.g. PTP). Lets keep these cases as separate return codes.

Dynamic features, like XTILEDATA, have an all zeroes init state and are not saved in init_fpstate, which means the corresponding bit is not set in the xfeatures bitmap of the init_fpstate header. But __copy_xstate_to_uabi_buf() retrieves addresses for both the tasks xstate and init_fpstate unconditionally via __raw_xsave_addr(). So if the tasks XSAVE buffer has a dynamic feature set, then the address retrieval for init_fpstate triggers the warning in __raw_xsave_addr() which checks the feature bit in the init_fpstate header. Remove the address retrieval from init_fpstate for extended features. They have an all zeroes init state so init_fpstate has zeros for them. Then zeroing the user buffer for the init state is the same as copying them from init_fpstate.

Instead they provide the fixed length of the hmac buffer. This length happens to be larger than the value returned by crypto_ahash_digestsize().

Chrome OS team hit the same issue in Feb, 2023 when trying to find work arounds for other issues with AX88172 devices. The use of devm_mdiobus_register() with usbnet devices results in the MDIO data being associated with the USB device. When the asix driver is unloaded, the USB device continues to exist and the corresponding "mdiobus_unregister()" is NOT called until the USB device is unplugged or unauthorized. So the next "modprobe asix" will fail because the MDIO phy sysfs attributes still exist. The 'easy' (from a design PoV) fix is to use the non-devm variants of mdiobus_* functions and explicitly manage this use in the asix_bind and asix_unbind function calls. I've not explored trying to fix usbnet initialization so devm_* stuff will work.

This means the early console is available as soon as the early param parsing happens, which is nice. It also means we need two different ways to pass this information, as this trick only works if the EFI stub is baked into the core kernel image, which is not always the case. Huacai reports that the preparatory refactoring that was needed to implement this alternative method for zboot resulted in a non-functional efifb earlycon for other cases as well, due to the reordering of the kernel image relocation with the population of the screen_info struct, and the latter now takes place after copying the image to its new location, which means we copy the old, uninitialized state. So let's ensure that the same-image version of alloc_screen_info() produces the correct screen_info pointer, by taking the displacement of the loaded image into account.

This adds a new devres each time. This may also happen at runtime, as dwc2_lowlevel_hw_enable() can be called from udc_start(). This can be seen with tracing: - echo 1 > /sys/kernel/debug/tracing/events/dev/devres_log/enable - go to low power - cat /sys/kernel/debug/tracing/trace A new "ADD" entry is found upon each low power cycle: ... devres_log: 49000000.usb-otg ADD 82a13bba devm_action_release (8 bytes) ... devres_log: 49000000.usb-otg ADD 49889daf devm_action_release (8 bytes) ... A second issue is addressed here: - regulator_bulk_enable() is called upon each PM cycle (suspend/resume). - regulator_bulk_disable() never gets called. So the reference count for these regulators constantly increase, by one upon each low power cycle, due to missing regulator_bulk_disable() call in __dwc2_lowlevel_hw_disable(). The original fix that introduced the devm_add_action_or_reset() call, fixed an issue during probe, that happens due to other errors in dwc2_driver_probe() -> dwc2_core_reset(). Then the probe fails without disabling regulators, when dr_mode == USB_DR_MODE_PERIPHERAL. Rather fix the error path: disable all the low level hardware in the error path, by using the "hsotg->ll_hw_enabled" flag. Checking dr_mode has been introduced to avoid a dual call to dwc2_lowlevel_hw_disable(). "ll_hw_enabled" should achieve the same (and is used currently in the remove() routine).

On STM32 this creates some weird race condition upon boot, when: - initially attached as a device, to a HOST - and there is a gadget script invoked to setup the device part. Below issue becomes systematic, as long as the gadget script isn't started by userland: the hardware PHYs (and so the clocks provided by the PHYs) remains disabled. It ends up in having an endless interrupt storm, before the watchdog resets the platform.

The host part is also not functional, until the gadget part is configured. The HW may only be disabled for peripheral mode (original init), e.g. dr_mode == USB_DR_MODE_PERIPHERAL, until the gadget driver initializes. But when in USB_DR_MODE_OTG, the HW should remain enabled, as the HCD part is able to run, while the gadget part isn't necessarily configured. I don't fully get the of purpose the original change, that claims disabling the hardware is missing. It creates conditions on SOCs using the PHY initialization to be completely non working in OTG mode. Original change [1] should be reworked to be platform specific.

The first occurs when a version of clang that supports zicsr or zifencei via '-march=' [1] (i.e, >= 17.x) is used in combination with a version of GNU binutils that do not recognize zicsr and zifencei in the '-march=' value (i.e., < 2.36): riscv64-linux-gnu-ld: -march=rv64i2p0_m2p0_a2p0_c2p0_zicsr2p0_zifencei2p0: Invalid or unknown z ISA extension: 'zifencei' riscv64-linux-gnu-ld: failed to merge target specific data of file fs/efivarfs/file.o riscv64-linux-gnu-ld: -march=rv64i2p0_m2p0_a2p0_c2p0_zicsr2p0_zifencei2p0: Invalid or unknown z ISA extension: 'zifencei' riscv64-linux-gnu-ld: failed to merge target specific data of file fs/efivarfs/super.o The second occurs when a version of clang that does not support zicsr or zifencei via '-march=' (i.e., <= 16.x) is used in combination with a version of GNU as that defaults to a newer ISA base spec, which requires specifying zicsr and zifencei in the '-march=' value explicitly (i.e, >= 2.38): ../arch/riscv/kernel/kexec_relocate.S: Assembler messages: ../arch/riscv/kernel/kexec_relocate.S:147: Error: unrecognized opcode `fence.i', extension `zifencei' required clang-12: error: assembler command failed with exit code 1 (use -v to see invocation) This is the same issue addressed by commit 6df2a016c0c8 ("riscv: fix build with binutils 2.38") (see [2] for additional information) but older versions of clang miss out on it because the cc-option check fails: clang-12: error: invalid arch name 'rv64imac_zicsr_zifencei', unsupported standard user-level extension 'zicsr' clang-12: error: invalid arch name 'rv64imac_zicsr_zifencei', unsupported standard user-level extension 'zicsr' To resolve the first issue, only attempt to add zicsr and zifencei to the march string when using the GNU assembler 2.38 or newer, which is when the default ISA spec was updated, requiring these extensions to be specified explicitly. LLVM implements an older version of the base specification for all currently released versions, so these instructions are available as part of the 'i' extension. If LLVM's implementation is updated in the future, a CONFIG_AS_IS_LLVM condition can be added to CONFIG_TOOLCHAIN_NEEDS_EXPLICIT_ZICSR_ZIFENCEI. To resolve the second issue, use version 2.2 of the base ISA spec when using an older version of clang that does not support zicsr or zifencei via '-march=', as that is the spec version most compatible with the one clang/LLVM implements and avoids the need to specify zicsr and zifencei explicitly due to still being a part of 'i'.

SoCs) the Bluetooth firmware seems to become unresponsive for a while after setting the BD address. On recent kernel versions (at least 5.17+) this often causes timeouts for subsequent commands, e.g. the HCI reset sent by the Bluetooth core during initialization: Bluetooth: hci0: Opcode 0x c03 failed: -110 Unfortunately this behavior does not seem to be documented anywhere. Experimentation suggests that the minimum necessary delay to avoid the problem is ~150us. However, to be sure add a sleep for > 1ms in case it is a bit longer on other firmware versions. Older kernel versions are likely also affected, although perhaps with slightly different errors or less probability. Side effects can easily hide the issue in most cases, e.g. unrelated incoming interrupts that cause the necessary delay.

Howlett" Date: Tue, 7 Mar 2023 13:02:46 -0500 Subject: [PATCH 943/976] maple_tree: fix mas_skip_node() end slot detection Patch series "Fix mas_skip_node() for mas_empty_area()", v2. mas_empty_area() was incorrectly returning an error when there was room. The issue was tracked down to mas_skip_node() using the incorrect end-of-slot count. Instead of using the nodes hard limit, the limit of data should be used. mas_skip_node() was also setting the min and max to that of the child node, which was unnecessary. Within these limits being set, there was also a bug that corrupted the maple state's max if the offset was set to the maximum node pivot. The bug was without consequence unless there was a sufficient gap in the next child node which would cause an error to be returned. This patch set fixes these errors by removing the limit setting from mas_skip_node() and uses the mas_data_end() for slot limits, and adds tests for all failures discovered. This patch (of 2): mas_skip_node() is used to move the maple state to the node with a higher limit. It does this by walking up the tree and increasing the slot count. Since slot count may not be able to be increased, it may need to walk up multiple times to find room to walk right to a higher limit node. The limit of slots that was being used was the node limit and not the last location of data in the node. This would cause the maple state to be shifted outside actual data and enter an error state, thus returning -EBUSY. The result of the incorrect error state means that mas_awalk() would return an error instead of finding the allocation space. The fix is to use mas_data_end() in mas_skip_node() to detect the nodes data end point and continue walking the tree up until it is safe to move to a node with a higher limit. The walk up the tree also sets the maple state limits so remove the buggy code from mas_skip_node(). Setting the limits had the unfortunate side effect of triggering another bug if the parent node was full and the there was no suitable gap in the second last child, but room in the next child. mas_skip_node() may also be passed a maple state in an error state from mas_anode_descend() when no allocations are available. Return on such an error state immediately.

This is to test the walking back up the tree at the end of nodes and error condition. Test inspired by the reproducer code provided by Snild Dolkow. The last test in the function tests for the case of a corrupted maple state caused by the incorrect limits set during mas_skip_node(). There needs to be a gap in the second last child and last child, but the search must rule out the second last child's gap. This would avoid correcting the maple state to the correct max limit and return an error.

Ensure that the maple tree is still valid by checking ksm_test_exit() after taking the mmap_lock in read mode, but before the for_each_vma() iterator dereferences a destroyed maple tree. Since the maple tree is destroyed, the flags telling lockdep to check an external lock has been cleared. Skip the for_each_vma() iterator to avoid dereferencing a maple tree without the external lock flag, which would create a lockdep warning.

However, this line of code in free_pages_prepare(): page->flags &= ~PAGE_FLAGS_CHECK_AT_PREP; clears most of page->flags, including PG_skip_kasan_poison, before calling should_skip_kasan_poison(), which meant that it would never return true as a result of the page flag being set. Therefore, fix the code to call should_skip_kasan_poison() before clearing the flags, as we were doing before the reverted patch. This fixes a measurable performance regression introduced in the reverted commit, where munmap() takes longer than intended if HW tags KASAN is supported and enabled at runtime. Without this patch, we see a single-digit percentage performance regression in a particular mmap()-heavy benchmark when enabling HW tags KASAN, and with the patch, there is no statistically significant performance impact when enabling HW tags KASAN.

Wong" Date: Tue, 21 Mar 2023 16:33:20 -0700 Subject: [PATCH 969/976] xfs: clear incore AGFL_RESET state if it's not needed Prior to commit 7ac2ff8bb371, when we loaded the incore perag structure with information from the AGF header, we would set or clear the pagf_agfl_reset field based on whether or not the AGFL list was misaligned within the block. IOWs, it's an incore state bit that's supposed to cache something in the ondisk metadata. Therefore, the code still needs to support clearing the incore bit if (somehow) the AGFL were to correct itself. It turns out that xfs_repair does exactly this -- phase 4 loads the AGF to scan the rmapbt for corrupt records, which can set NEEDS_AGFL_RESET. The scan unsets AGF_INIT but doesn't unset NEEDS_AGFL_RESET. Phase 5 totally rewrites the AGFL and fixes the alignment problem, didn't clear NEEDS_AGFL_RESET historically, and reloads the perag state to fix the freelist. This results in the AGFL being reset based on stale data, which then causes the new AGFL blocks to be leaked. A subsequent xfs_repair -n then complains about the leaks. One could argue that phase 5 ought to clear this bit directly when it reloads the perag AGF data after rewriting the AGFL, but libxfs used to handle this for us, so it should go back to doing that. Found by fuzzing flfirst = ones in xfs/352. Fixes: 7ac2ff8bb371 ("xfs: perags need atomic operational state") Signed-off-by: Darrick J.

Kubernetes had example when they were doing umount -f when files were open which caused the share to become unusable until the files were closed (and the umount retried). Fix this so that TID_EXITING is not set until we are about to send the tree disconnect (not at the beginning of forced umounts in umount_begin) so that if "umount -f" fails (due to open files or references) the mount is still usable.
