[PATCH can] can: netlink: can_changelink(): allow disabling of automatic restart

by Marc Kleine-Budde

Since the commit c1f3f9797c1f ("can: netlink: can_changelink(): fix NULL pointer deref of struct can_priv::do_set_mode"), the automatic restart delay can only be set for devices that implement the restart handler struct can_priv::do_set_mode. As it makes no sense to configure a automatic restart for devices that doesn't support it. However, since systemd commit 13ce5d4632e3 ("network/can: properly handle CAN.RestartSec=0") [1], systemd-networkd correctly handles a restart delay of "0" (i.e. the restart is disabled). Which means that a disabled restart is always configured in the kernel. On systems with both changes active this causes that CAN interfaces that don't implement a restart handler cannot be brought up by systemd-networkd. Solve this problem by allowing a delay of "0" to be configured, even if the device does not implement a restart handler.

[PATCH 1/2] ASoC: qcom: sdw: fix memory leak for sdw_stream_runtime

by Srinivas Kandagatla

For some reason we endedup allocating sdw_stream_runtime for every cpu dai, this has two issues. 1. we never set snd_soc_dai_set_stream for non soundwire dai, which means there is no way that we can free this, resulting in memory leak 2. startup and shutdown callbacks can be called without hw_params callback called. This combination results in memory leak because machine driver sruntime array pointer is only set in hw_params callback. Fix this by 1. adding a helper function to get sdw_runtime for substream which can be used by shutdown callback to get hold of sruntime to free. 2. only allocate sdw_runtime for soundwire dais.

[syzbot ci] Re: Fix stale IOTLB entries for kernel address space

by syzbot ci

syzbot ci has tested the following series [v6] Fix stale IOTLB entries for kernel address space https://lore.kernel.org/all/20251014130437.1090448-1-baolu.lu@linux.intel.c… * [PATCH v6 1/7] mm: Add a ptdesc flag to mark kernel page tables * [PATCH v6 2/7] mm: Actually mark kernel page table pages * [PATCH v6 3/7] x86/mm: Use 'ptdesc' when freeing PMD pages * [PATCH v6 4/7] mm: Introduce pure page table freeing function * [PATCH v6 5/7] x86/mm: Use pagetable_free() * [PATCH v6 6/7] mm: Introduce deferred freeing for kernel page tables * [PATCH v6 7/7] iommu/sva: Invalidate stale IOTLB entries for kernel address space and found the following issues: * KASAN: use-after-free Read in pmd_set_huge * KASAN: use-after-free Read in vmap_range_noflush * PANIC: double fault in search_extable Full

[DISCUSSION] Fixing bad pmd due to a race condition between change_prot_numa() and THP migration in pre-6.5 kernels.

by Harry Yoo

Hi. This is supposed to be a patch, but I think it's worth discussing how it should be backported to -stable, so I've labeled it as [DISCUSSION]. The bug described below was unintentionally fixed in v6.5 and not backported to -stable. So technically I would need to use "Option 3" [A], but since the original patch [B] did not intend to fix a bug (and it's also part of a larger patch series), it looks quite different from the patch below, and I'm not sure what the backport should look like. I think there are probably two options: 1. Provide the description of the original patch along with a very long, detailed explanation of why the patch deviates from the upstream version, or 2. Post the patch below with a clarification that it was fixed upstream by commit 670ddd8cdcbd1. Any thoughts? [A] https://www.kernel.org/doc/html/latest/process/stable-kernel-rules.html#opt… [B] https://lkml.kernel.org/r/725a42a9-91e9-c868-925-e3a5fd40bb4f@google.com (Upstream commit 670ddd8cdcbd1) In any case, no matter how we backport this, it needs some review and feedback would be appreciated. The patch applies to v6.1 and v5.15, and v5.10 but not v5.4.

For the race condition described above to occur: 1) AutoNUMA must be unmapping a range of pages, with at least part of the range already unmapped by AutoNUMA. 2) While AutoNUMA is in the process of unmapping, a NUMA hinting fault occurs within that range, specifically when we are about to unmap the PMD entry, between the is_swap_pmd() and pmd_trans_huge() checks. So this is a really rare race condition and it's observed that it takes usually a few days of autonuma-intensive testing to trigger. A bit of history on a similar race condition in the past: In fact, a similar race condition caused by not checking pmd_trans_huge() atomically was reported [1] in 2017. However, instead of the patch [1], another patch series [3] fixed the problem [2] by not clearing the pmd entry but invaliding it instead (so that pmd_trans_huge() would still return true). Despite patch series [3], the bad pmd error continued to be reported in mainline. As a result, [1] was resurrected [4] and it landed mainline in 2020 in a hope that it would resolve the issue. However, now it turns out that [3] was not sufficient. Fix this race condition by checking is_swap_pmd() and pmd_trans_huge() atomically. With that, the kernel should see either pmd_trans_huge() == true, or is_swap_pmd() == true when another task is migrating the page concurrently. This bug was introduced when THP migration support was added. More specifically, by commit 84c3fc4e9c56 ("mm: thp: check pmd migration entry in common path")). It is unintentionally fixed since v6.5 by commit 670ddd8cdcbd1 ("mm/mprotect: delete pmd_none_or_clear_bad_unless_trans_huge()") while removing pmd_none_or_clear_bad_unless_trans_huge() function. But it's not backported to -stable because it was fixed unintentionally.

[PATCH 6.12.y] drm/amd/display: fix dmub access race condition

by Timothy Pearson

From: Aurabindo Pillai <aurabindo.pillai(a)amd.com> Justificiation: This fixes DisplayPort lockups on Polaris GPUs during DPMS transitions, which have been a major headache on our POWER9 platforms. Backport to Debian stable kernel version. [ Upstream commit c210b757b400959577a5a17b783b5959b82baed8 ] Accessing DC from amdgpu_dm is usually preceded by acquisition of dc_lock mutex. Most of the DC API that DM calls are under a DC lock. However, there are a few that are not. Some DC API called from interrupt context end up sending DMUB commands via a DC API, while other threads were using DMUB. This was apparent from a race between calls for setting idle optimization enable/disable and the DC API to set vmin/vmax. Offload the call to dc_stream_adjust_vmin_vmax() to a thread instead of directly calling them from the interrupt handler such that it waits for dc_lock.

[PATCH 0/3] gpio: idio-16: Fix regmap initialization errors

by William Breathitt Gray

The migration of IDIO-16 GPIO drivers to the regmap API resulted in some regressions to the gpio-104-idio-16, gpio-pci-idio-16, and gpio-idio-16 modules. Specifically, the 104-idio-16 and pci-idio-16 GPIO drivers utilize regmap caching and thus must set max_register for their regmap_config, while gpio-idio-16 requires fixed_direction_output to represent the fixed direction of the IDIO-16 GPIO lines. Fixes for these regressions are provided by this series.

Remove the separate inv_icm42600_disable_pm callback, as it's no longer needed with the devm-managed approach. Using devm_pm_runtime_enable() also fixes the missing disable of autosuspend. Update inv_icm42600_disable_vddio_reg() to only disable the regulator if the device is not suspended i.e. powered-down, preventing unbalanced disables. Also remove redundant error msg on regulator_disable(), the regulator framework already emits an error message when regulator_disable() fails. This simplifies the PM setup and avoids manipulating the usage counter unnecessarily.

This is as per the DPHY initialization sequence as mentioned in J721E TRM [1] at section "12.7.2.4.1.2.1 Start-up Sequence Timing Diagram". It shows O_CMN_READY polling at the end after common configuration pin setup where the common configuration pin setup step enables state machine as referenced in "Table 12-1533.

If no_newoffset is FALSE, an offset is not given. This means that client does not try to update the file size.

Truncating head block from 0xc. This is because the CRCs generated by i386 and other architectures always diff. The reason for that is that sizeof(struct xlog_rec_header) returns different values for i386 vs the rest (324 vs 328), because the struct is not sizeof(uint64_t) aligned, and i386 has odd struct size alignment rules. This issue goes back to commit 13cdc853c519 ("Add log versioning, and new super block field for the log stripe") in the xfs-import tree, which adds log v2 support and the h_size field that causes the unaligned size. At that time it only mattered for the crude debug only log header checksum, but with commit 0e446be44806 ("xfs: add CRC checks to the log") it became a real issue for v5 file system, because now there is a proper CRC, and regular builds actually expect it match. Fix this by allowing checksums with and without the padding.

Truncating head block from 0xc. This is because the CRCs generated by i386 and other architectures always diff. The reason for that is that sizeof(struct xlog_rec_header) returns different values for i386 vs the rest (324 vs 328), because the struct is not sizeof(uint64_t) aligned, and i386 has odd struct size alignment rules. This issue goes back to commit 13cdc853c519 ("Add log versioning, and new super block field for the log stripe") in the xfs-import tree, which adds log v2 support and the h_size field that causes the unaligned size. At that time it only mattered for the crude debug only log header checksum, but with commit 0e446be44806 ("xfs: add CRC checks to the log") it became a real issue for v5 file system, because now there is a proper CRC, and regular builds actually expect it match. Fix this by allowing checksums with and without the padding.

Truncating head block from 0xc. This is because the CRCs generated by i386 and other architectures always diff. The reason for that is that sizeof(struct xlog_rec_header) returns different values for i386 vs the rest (324 vs 328), because the struct is not sizeof(uint64_t) aligned, and i386 has odd struct size alignment rules. This issue goes back to commit 13cdc853c519 ("Add log versioning, and new super block field for the log stripe") in the xfs-import tree, which adds log v2 support and the h_size field that causes the unaligned size. At that time it only mattered for the crude debug only log header checksum, but with commit 0e446be44806 ("xfs: add CRC checks to the log") it became a real issue for v5 file system, because now there is a proper CRC, and regular builds actually expect it match. Fix this by allowing checksums with and without the padding.

[PATCH 6.6 1/2] block: fix race between set_blocksize and read paths

by Mahmoud Adam

From: "Darrick J. Wong" <djwong(a)kernel.org> commit c0e473a0d226479e8e925d5ba93f751d8df628e9 upstream. With the new large sector size support, it's now the case that set_blocksize can change i_blksize and the folio order in a manner that conflicts with a concurrent reader and causes a kernel crash. Specifically, let's say that udev-worker calls libblkid to detect the labels on a block device. The read call can create an order-0 folio to read the first 4096 bytes from the disk. But then udev is preempted. Next, someone tries to mount an 8k-sectorsize filesystem from the same block device. The filesystem calls set_blksize, which sets i_blksize to 8192 and the minimum folio order to 1. Now udev resumes, still holding the order-0 folio it allocated. It then tries to schedule a read bio and do_mpage_readahead tries to create bufferheads for the folio. Unfortunately, blocks_per_folio == 0 because the page size is 4096 but the blocksize is 8192 so no bufferheads are attached and the bh walk never sets bdev. We then submit the bio with a NULL block device and crash. Therefore, truncate the page cache after flushing but before updating i_blksize. However, that's not enough -- we also need to lock out file IO and page faults during the update. Take both the i_rwsem and the invalidate_lock in exclusive mode for invalidations, and in shared mode for read/write operations. I don't know if this is the correct fix, but xfs/259 found it.

[PATCH v3 1/5] mm: fix off-by-one error in VMA count limit checks

by Kalesh Singh

The VMA count limit check in do_mmap() and do_brk_flags() uses a strict inequality (>), which allows a process's VMA count to exceed the configured sysctl_max_map_count limit by one. A process with mm->map_count == sysctl_max_map_count will incorrectly pass this check and then exceed the limit upon allocation of a new VMA when its map_count is incremented. Other VMA allocation paths, such as split_vma(), already use the correct, inclusive (>=) comparison. Fix this bug by changing the comparison to be inclusive in do_mmap() and do_brk_flags(), bringing them in line with the correct behavior of other allocation paths.

[PATCH 6.1.y 00/12] timers: Provide timer_shutdown[_sync]()

by Jeongjun Park

The "timers: Provide timer_shutdown[_sync]()" patch series implemented a useful feature that addresses various bugs caused by attempts to rearm shutdown timers. https://lore.kernel.org/all/20221123201306.823305113@linutronix.de/ However, this patch series was not fully backported to versions prior to 6.2, requiring separate patches for older kernels if these bugs were encountered. The biggest problem with this is that even if these bugs were discovered and patched in the upstream kernel, if the maintainer or author didn't create a separate backport patch for versions prior to 6.2, the bugs would remain untouched in older kernels. Therefore, to reduce the hassle of having to write a separate patch, we should backport the remaining unbackported commits from the "timers: Provide timer_shutdown[_sync]()" patch series to versions prior to 6.2. --- Documentation/RCU/Design/Requirements/Requirements.rst | 2 +- Documentation/core-api/local_ops.rst | 2 +- Documentation/kernel-hacking/locking.rst | 17 ++++--- Documentation/timers/hrtimers.rst | 2 +- Documentation/translations/it_IT/kernel-hacking/locking.rst | 14 +++-- Documentation/translations/zh_CN/core-api/local_ops.rst | 2 +- arch/arm/mach-spear/time.c | 8 +-- drivers/bluetooth/hci_qca.c | 10 +++- drivers/clocksource/arm_arch_timer.c | 12 ++--- drivers/clocksource/timer-sp804.c | 6 +-- include/linux/timer.h | 2 + kernel/time/timer.c | 311 ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++-------------------- 12 files changed, 299 insertions(+), 89 deletions(-)

When completing single-step of a suspended breakpoint, we do not call local_daif_restore(DAIF_PROCCTX) before calling exit_to_user_mode(), leaving all DAIF exceptions masked. When pseudo-NMIs are not in use this is benign. When pseudo-NMIs are in use, this is unsound. At this point interrupts are masked by both DAIF.IF and PMR_EL1, and subsequent irq flag manipulation may not work correctly. For example, a subsequent local_irq_enable() within exit_to_user_mode_loop() will only unmask interrupts via PMR_EL1 (leaving those masked via DAIF.IF), and anything depending on interrupts being unmasked (e.g. delivery of signals) will not work correctly. This was detected by CONFIG_ARM64_DEBUG_PRIORITY_MASKING. Move the call to `try_step_suspended_breakpoints()` outside of the check so that interrupts can be unmasked even if we don't call the step handler.

[PATCH mt76 v3] wifi: mt76: Fix DTS power-limits on little endian systems

by Sven Eckelmann (Plasma Cloud)

The power-limits for ru and mcs and stored in the devicetree as bytewise array (often with sizes which are not a multiple of 4). These arrays have a prefix which defines for how many modes a line is applied. This prefix is also only a byte - but the code still tried to fix the endianness of this byte with a be32 operation. As result, loading was mostly failing or was sending completely unexpected values to the firmware. Since the other rates are also stored in the devicetree as bytewise arrays, just drop the u32 access + be32_to_cpu conversion and directly access them as bytes arrays.

[PATCH v2] tcpm: switch check for role_sw device with fw_node

by Michael Grzeschik

When there is no port entry in the tcpci entry itself, the driver will trigger an error message "OF: graph: no port node found in /...../typec" . It is documented that the dts node should contain an connector entry with ports and several port pointing to devices with usb-role-switch property set. Only when those connector entry is missing, it should check for port entries in the main node. We switch the search order for looking after ports, which will avoid the failure message while there are explicit connector entries.

[PATCH 5.4-6.17 0/2] arm64: errata: Apply workarounds for Neoverse-V3AE

by Ryan Roberts

Hi All, This series is a backport intended for all supported stable kernels (5.4-6.17) of the recent errata workarounds for Neoverse-V3AE, which were originally posted at: https://lore.kernel.org/all/20250919145832.4035534-1-ryan.roberts@arm.com/ ... and were originally merged upstream in v6.18-rc1. I've tested that these patches apply to 5.4-6.12 without issue, but there is a trivial conflict to resolve in silicon-errata.rst for it to apply to 6.16 and 6.17. Are you happy to deal with that or should I send a separate series? Thanks, Ryan Mark Rutland (2): arm64: cputype: Add Neoverse-V3AE definitions arm64: errata: Apply workarounds for Neoverse-V3AE Documentation/arch/arm64/silicon-errata.rst | 2 ++ arch/arm64/Kconfig | 1 + arch/arm64/include/asm/cputype.h | 2 ++ arch/arm64/kernel/cpu_errata.c | 1 + 4 files changed, 6 insertions(+) -- 2.43.0

However if it's not released, the BAR2 resize fails. During the vram probe it can't be released as it's already in use by xe_mmio for early register access. Add a new function in xe_vram and let xe_pci call it directly before even early device probe. This allows the BAR2 to resize in cases BAR0 also needs to move, assuming there aren't other reasons to hold that move: [] xe 0000:03:00.0: vgaarb: deactivate vga console [] xe 0000:03:00.0: [drm] Attempting to resize bar from 8192MiB -> 16384MiB [] xe 0000:03:00.0: BAR 0 [mem 0x83000000-0x83ffffff 64bit]: releasing [] xe 0000:03:00.0: BAR 2 [mem 0x4000000000-0x41ffffffff 64bit pref]: releasing [] pcieport 0000:02:01.0: bridge window [mem 0x4000000000-0x41ffffffff 64bit pref]: releasing [] pcieport 0000:01:00.0: bridge window [mem 0x4000000000-0x41ffffffff 64bit pref]: releasing [] pcieport 0000:01:00.0: bridge window [mem 0x4000000000-0x43ffffffff 64bit pref]: assigned [] pcieport 0000:02:01.0: bridge window [mem 0x4000000000-0x43ffffffff 64bit pref]: assigned [] xe 0000:03:00.0: BAR 2 [mem 0x4000000000-0x43ffffffff 64bit pref]: assigned [] xe 0000:03:00.0: BAR 0 [mem 0x83000000-0x83ffffff 64bit]: assigned [] pcieport 0000:00:01.0: PCI bridge to [bus 01-04] [] pcieport 0000:00:01.0: bridge window [mem 0x83000000-0x840fffff] [] pcieport 0000:00:01.0: bridge window [mem 0x4000000000-0x44007fffff 64bit pref] [] pcieport 0000:01:00.0: PCI bridge to [bus 02-04] [] pcieport 0000:01:00.0: bridge window [mem 0x83000000-0x840fffff] [] pcieport 0000:01:00.0: bridge window [mem 0x4000000000-0x43ffffffff 64bit pref] [] pcieport 0000:02:01.0: PCI bridge to [bus 03] [] pcieport 0000:02:01.0: bridge window [mem 0x83000000-0x83ffffff] [] pcieport 0000:02:01.0: bridge window [mem 0x4000000000-0x43ffffffff 64bit pref] [] xe 0000:03:00.0: [drm] BAR2 resized to 16384M [] xe 0000:03:00.0: [drm:xe_pci_probe [xe]] BATTLEMAGE e221:0000 dgfx:1 gfx:Xe2_HPG (20.02) ... For BMG there are additional fix needed in the PCI side, but this helps getting it to a working resize. All the rebar logic is more pci-specific than xe-specific and can be done very early in the probe sequence. In future it would be good to move it out of xe_vram.c, but this refactor is left for later.

[PATCH v2 0/3] ASoC: SOF: ipc4/Intel: Fix the host buffer constraint

by Peter Ujfalusi

Hi, Changes since v1: - SHAs for Fixes tag corrected (sorry) The size of the DSP host buffer was incorrectly defined as 2ms while it is 4ms and the ChainDMA PCMs are using 5ms as host facing buffer. The constraint will be set against the period time rather than the buffer time to make sure that application will not face with xruns when the DMA bursts to refill the host buffer. The minimal period size will be also used by Pipewire in case of SOF cards to set the headroom to a length which will avoid the cases when the hw_ptr jumps over the appl_ptr because of a burst. Iow, it will make Pipewire to keep a safe distance from the hw_ptr. https://github.com/thesofproject/linux/issues/5284 https://gitlab.freedesktop.org/pipewire/wireplumber/-/merge_requests/740 https://gitlab.freedesktop.org/pipewire/pipewire/-/merge_requests/2548 Regards, Peter --- Peter Ujfalusi (3): ASoC: SOF: ipc4-topology: Correct the minimum host DMA buffer size ASoC: SOF: ipc4-topology: Account for different ChainDMA host buffer size ASoC: SOF: Intel: hda-pcm: Place the constraint on period time instead of buffer time sound/soc/sof/intel/hda-pcm.c | 29 +++++++++++++++++++++-------- sound/soc/sof/ipc4-topology.c | 9 +++++++-- sound/soc/sof/ipc4-topology.h | 7 +++++-- 3 files changed, 33 insertions(+), 12 deletions(-) -- 2.51.0

[PATCH 5.10] comedi: Make insn_rw_emulate_bits() do insn->n samples

by Andrey Troshin

From: Ian Abbott <abbotti(a)mev.co.uk> commit 7afba9221f70d4cbce0f417c558879cba0eb5e66 upstream. The `insn_rw_emulate_bits()` function is used as a default handler for `INSN_READ` instructions for subdevices that have a handler for `INSN_BITS` but not for `INSN_READ`. Similarly, it is used as a default handler for `INSN_WRITE` instructions for subdevices that have a handler for `INSN_BITS` but not for `INSN_WRITE`. It works by emulating the `INSN_READ` or `INSN_WRITE` instruction handling with a constructed `INSN_BITS` instruction. However, `INSN_READ` and `INSN_WRITE` instructions are supposed to be able read or write multiple samples, indicated by the `insn->n` value, but `insn_rw_emulate_bits()` currently only handles a single sample. For `INSN_READ`, the comedi core will copy `insn->n` samples back to user-space. (That triggered KASAN kernel-infoleak errors when `insn->n` was greater than 1, but that is being fixed more generally elsewhere in the comedi core.) Make `insn_rw_emulate_bits()` either handle `insn->n` samples, or return an error, to conform to the general expectation for `INSN_READ` and `INSN_WRITE` handlers.

[PATCH v2 06/14] iommu/mediatek: fix device leaks on probe()

by Johan Hovold

Re: [PATCH v4 15/19] lib/crc32: make crc32c() go directly to lib

by Askar Safin

Eric Biggers <ebiggers(a)kernel.org>: > Now that the lower level __crc32c_le() library function is optimized for This patch (i. e. 38a9a5121c3b ("lib/crc32: make crc32c() go directly to lib")) solves actual bug I found in practice. So, please, backport it to stable kernels. I did bisect. It is possible to apply this patch on top of v6.12.48 without conflicts. The bug actually prevents me for using my system (more details below). Here is steps to reproduce bug I noticed. Build kernel so: $ cat /tmp/mini CONFIG_64BIT=y CONFIG_PRINTK=y CONFIG_SERIAL_8250=y CONFIG_TTY=y CONFIG_SERIAL_8250_CONSOLE=y CONFIG_BLK_DEV_INITRD=y CONFIG_RD_GZIP=y CONFIG_BINFMT_ELF=y CONFIG_BINFMT_SCRIPT=y CONFIG_PROC_FS=y CONFIG_SYSFS=y CONFIG_DEVTMPFS=y CONFIG_MODULES=y CONFIG_BTRFS_FS=m CONFIG_MODULE_COMPRESS=y CONFIG_MODULE_COMPRESS_XZ=y CONFIG_MODULE_COMPRESS_ALL=y CONFIG_MODULE_DECOMPRESS=y CONFIG_PRINTK_TIME=y $ make allnoconfig KCONFIG_ALLCONFIG=/tmp/mini $ make Then create initramfs, which contains statically built busybox (I used busybox v1.37.0 (Debian 1:1.37.0-6+b3)) and modules we just created. Then run Qemu using command line similar to this: qemu-system-x86_64 -kernel arch/x86/boot/bzImage -initrd i.gz -append 'console=ttyS0 panic=1 rdinit=/bin/busybox sh' -m 256 -no-reboot -enable-kvm -serial stdio -display none Then in busybox shell type this: # mkdir /proc # busybox mount -t proc proc /proc # modprobe btrfs On buggy kernels I get this output: # modprobe btrfs [ 19.614228] raid6: skipped pq benchmark and selected sse2x4 [ 19.614638] raid6: using intx1 recovery algorithm [ 19.616569] xor: measuring software checksum speed [ 19.616937] prefetch64-sse : 42616 MB/sec [ 19.617270] generic_sse : 41320 MB/sec [ 19.617531] xor: using function: prefetch64-sse (42616 MB/sec) [ 19.619731] Invalid ELF header magic: != ELF modprobe: can't load module libcrc32c (kernel/lib/libcrc32c.ko.xz): unknown symbol in module, or unknown parameter The bug is reproducible on all kernels from v6.12 until this commit. And it is not reproducible on all kernels, which contain this commit. I found this using bisect. This bug actually breaks my workflow. I have btrfs as root filesystem. Initramfs, generated by Debian, doesn't suit my needs. So I'm going to create my own initramfs from scratch. (Note that I use Debian Trixie, which has v6.12.48 kernel.) During testing this initramfs in Qemu I noticed that command "modprobe btrfs" fails with error given above. (I not yet tried to test this initramfs on real hardware.) So, this bug actually breaks my workflow. So, please backport this patch (i. e. 38a9a5121c3b ("lib/crc32: make crc32c() go directly to lib")) to stable kernels. I tested that this patch can be applied without conflicts on top of v6.12.48, and this patch indeed fixes the bug for v6.12.48. If you want, I can give more info. It is possible that this is in fact bug in busybox, not in Linux. But still I think that backporting this patch is good idea. This busybox thread my be related: https://lists.busybox.net/pipermail/busybox/2023-May/090309.html -- Askar Safin

[PATCH v2 00/27 5.10.y] Backport minmax.h updates from v6.17-rc7

by Eliav Farber

This series backports 27 patches to update minmax.h in the 5.10.y branch, aligning it with v6.17-rc7. The ultimate goal is to synchronize all long-term branches so that they include the full set of minmax.h changes. - 6.12.y has already been backported; the changes are included in v6.12.49. - 6.6.y has already been backported; the changes are included in v6.6.109. - 6.1.y has already been backported; the changes are currently in the 6.1-stable tree. - 5.15.y has already been backported; the changes are currently in the 5.15-stable tree. The key motivation is to bring in commit d03eba99f5bf ("minmax: allow min()/max()/clamp() if the arguments have the same signedness"), which is missing in kernel 5.10.y. In mainline, this change enables min()/max()/clamp() to accept mixed argument types, provided both have the same signedness. Without it, backported patches that use these forms may trigger compiler warnings, which escalate to build failures when -Werror is enabled. The first two patches in this series were added to prevent build failures caused by changes introduced later in minmax.h. - Commit 92d23c6e9415 ("overflow, tracing: Define the is_signed_type() macro once") is needed for commit 75ca38c1960f ("minmax: allow min()/max()/clamp()"). - Commit cea628008fc8 ("btrfs: remove duplicated in_range() macro") is needed for commit f9bff0e31881 ("minmax: add in_range() macro"). The changes were tested using `make allyesconfig` and `make allmodconfig` for arm64, arm, x86_64 and i386 architectures. Changes in v2: The series was updated after initially backporting and approving the newer long-term branches. Andy Shevchenko (2): minmax: deduplicate __unconst_integer_typeof() minmax: fix header inclusions Bart Van Assche (1): overflow, tracing: Define the is_signed_type() macro once David Laight (11): minmax: allow min()/max()/clamp() if the arguments have the same signedness. minmax: fix indentation of __cmp_once() and __clamp_once() minmax: allow comparisons of 'int' against 'unsigned char/short' minmax: relax check to allow comparison between unsigned arguments and signed constants minmax.h: add whitespace around operators and after commas minmax.h: update some comments minmax.h: reduce the #define expansion of min(), max() and clamp() minmax.h: use BUILD_BUG_ON_MSG() for the lo < hi test in clamp() minmax.h: move all the clamp() definitions after the min/max() ones minmax.h: simplify the variants of clamp() minmax.h: remove some #defines that are only expanded once Herve Codina (1): minmax: Introduce {min,max}_array() Jason A.

[PATCH v3] serial: 8250_dw: handle reset control deassert error

by Artem Shimko

Check the return value of reset_control_deassert() in the probe function to prevent continuing probe when reset deassertion fails. Previously, reset_control_deassert() was called without checking its return value, which could lead to probe continuing even when the device reset wasn't properly deasserted. The fix checks the return value and returns an error with dev_err_probe() if reset deassertion fails, providing better error handling and diagnostics.

[PATCH wireless-next v2 1/4] wifi: cfg80211: add an hrtimer based delayed work item

by Miri Korenblit

From: Benjamin Berg <benjamin.berg(a)intel.com> The normal timer mechanism assume that timeout further in the future need a lower accuracy. As an example, the granularity for a timer scheduled 4096 ms in the future on a 1000 Hz system is already 512 ms. This granularity is perfectly sufficient for e.g. timeouts, but there are other types of events that will happen at a future point in time and require a higher accuracy. Add a new wiphy_hrtimer_work type that uses an hrtimer internally. The API is almost identical to the existing wiphy_delayed_work and it can be used as a drop-in replacement after minor adjustments. The work will be scheduled relative to the current time with a slack of 1 millisecond.

[PATCH 1/4] wifi: cfg80211: add an hrtimer based delayed work item

by Miri Korenblit

From: Benjamin Berg <benjamin.berg(a)intel.com> The normal timer mechanism assume that timeout further in the future need a lower accuracy. As an example, the granularity for a timer scheduled 4096 ms in the future on a 1000 Hz system is already 512 ms. This granularity is perfectly sufficient for e.g. timeouts, but there are other types of events that will happen at a future point in time and require a higher accuracy. Add a new wiphy_hrtimer_work type that uses an hrtimer internally. The API is almost identical to the existing wiphy_delayed_work and it can be used as a drop-in replacement after minor adjustments. The work will be scheduled relative to the current time with a slack of 1 millisecond.

[PATCH 5.10.y] wifi: rt2x00: use explicitly signed or unsigned types

by Eliav Farber

From: "Jason A. Donenfeld" <Jason(a)zx2c4.com> commit 66063033f77e10b985258126a97573f84bb8d3b4 upstream. On some platforms, `char` is unsigned, but this driver, for the most part, assumed it was signed. In other places, it uses `char` to mean an unsigned number, but only in cases when the values are small. And in still other places, `char` is used as a boolean. Put an end to this confusion by declaring explicit types, depending on the context.

The point of this design is enabling epoll to scale well with large number of producers, as multiple producers can hold the read lock at the same time. Unfortunately, this implementation may cause scheduling priority inversion problem. Suppose the consumer has higher scheduling priority than the producer. The consumer needs to acquire the write lock, but may be blocked by the producer holding the read lock. Since read-write semaphore does not support priority-boosting for the readers (even with CONFIG_PREEMPT_RT=y), we have a case of priority inversion: a higher priority consumer is blocked by a lower priority producer. This problem was reported in [1]. Furthermore, this could also cause stall problem, as described in [2]. Fix this problem by replacing rwlock with spinlock. This reduces the event bandwidth, as the producers now have to contend with each other for the spinlock. According to the benchmark from https://github.com/rouming/test-tools/blob/master/stress-epoll.c: On 12 x86 CPUs: Before After Diff threads events/ms events/ms 8 7162 4956 -31% 16 8733 5383 -38% 32 7968 5572 -30% 64 10652 5739 -46% 128 11236 5931 -47% On 4 riscv CPUs: Before After Diff threads events/ms events/ms 8 2958 2833 -4% 16 3323 3097 -7% 32 3451 3240 -6% 64 3554 3178 -11% 128 3601 3235 -10% Although the numbers look bad, it should be noted that this benchmark creates multiple threads who do nothing except constantly generating new epoll events, thus contention on the spinlock is high. For real workload, the event rate is likely much lower, and the performance drop is not as bad. Using another benchmark (perf bench epoll wait) where spinlock contention is lower, improvement is even observed on x86: On 12 x86 CPUs: Before: Averaged 110279 operations/sec (+- 1.09%), total secs = 8 After: Averaged 114577 operations/sec (+- 2.25%), total secs = 8 On 4 riscv CPUs: Before: Averaged 175767 operations/sec (+- 0.62%), total secs = 8 After: Averaged 167396 operations/sec (+- 0.23%), total secs = 8 In conclusion, no one is likely to be upset over this change. After all, spinlock was used originally for years, and the commit which converted to rwlock didn't mention a real workload, just that the benchmark numbers are nice. This patch is not exactly the revert of commit a218cc491420 ("epoll: use rwlock in order to reduce ep_poll_callback() contention"), because git revert conflicts in some places which are not obvious on the resolution. This patch is intended to be backported, therefore go with the obvious approach: - Replace rwlock_t with spinlock_t one to one - Delete list_add_tail_lockless() and chain_epi_lockless(). These were introduced to allow producers to concurrently add items to the list. But now that spinlock no longer allows producers to touch the event list concurrently, these two functions are not necessary anymore.
