[PATCH] s390/vfio-ap: lock mdev object when handling mdev remove request

by Anthony Krowiak

The vfio_ap_mdev_request function in drivers/s390/crypto/vfio_ap_ops.c accesses fields of an ap_matrix_mdev object without ensuring that the object is accessed by only one thread at a time.

[PATCH 6.12.y 00/60] `alloc`, `#[expect]` and "Custom FFI"

by Miguel Ojeda

Hi Greg, Sasha, Please consider this series for 6.12.y. It should apply cleanly on top of v6.12.18. These are the patches to backport the `alloc` series for Rust, which will be useful for Rust Android Binder and others. It also means that, with this applied, we will not rely on the standard library `alloc` (and the unstable `cfg` option we used) anymore in any stable kernel that supports several Rust versions, so e.g. upstream Rust could consider removing that `cfg` if they needed. The entire series of cherry-picks apply almost cleanly (only 2 trivial conflicts) -- to achieve that, I included the `#[expect]` support, which will make future backports that use that feature easier anyway. That series also enabled some Clippy warnings. We could reduce the series, but the end result is warning-free and Clippy is opt-in anyway. Out-of-tree code could, of course, see some warnings if they use it. I also included a bunch of Clippy warnings cleanups for the DRM QR Code to have this series clean up to Rust 1.85.0 (the latest stable), but I could send them separately if needed. Finally, I included the "Custom FFI" series backport, which in turn solves the arm64 + Rust 1.85.0 + `CONFIG_RUST_FW_LOADER_ABSTRACTIONS=y` issue. It will also make future patches easier to backport, since we will have the same `ffi::` types. I tested that the entire series builds between every commit for x86_64 `LLVM=1` with the latest stable and minimum supported Rust compiler versions. I also ran my usual stable kernel tests on the end result; that is, boot-tested in QEMU for several architectures etc. In v6.12.18 for loongarch there is an unrelated error that was not there in v6.12.17 when I did a previous test run -- reported separately. Things could still break, so extra tests on the next -rc from users in Cc here would be welcome -- thanks!

[PATCH v3 1/2] regulator: dummy: force synchronous probing

by Christian Eggers

Sometimes I get a NULL pointer dereference at boot time in kobject_get() with the following call stack: anatop_regulator_probe() devm_regulator_register() regulator_register() regulator_resolve_supply() kobject_get() By placing some extra BUG_ON() statements I could verify that this is raised because probing of the 'dummy' regulator driver is not completed ('dummy_regulator_rdev' is still NULL). In the JTAG debugger I can see that dummy_regulator_probe() and anatop_regulator_probe() can be run by different kernel threads (kworker/u4:*). I haven't further investigated whether this can be changed or if there are other possibilities to force synchronization between these two probe routines. On the other hand I don't expect much boot time penalty by probing the 'dummy' regulator synchronously.

[PATCH 5.15.y] fs/ntfs3: Fix shift-out-of-bounds in ntfs_fill_super

by Miguel García

From: Konstantin Komarov <almaz.alexandrovich(a)paragon-software.com> commit 91a4b1ee78cb ("fs/ntfs3: Fix shift-out-of-bounds in ntfs_fill_super") This patch is a backport and fixes an UBSAN warning about shift-out-of-bounds in ntfs_fill_super() function of the NTFS3 driver. The original code incorrectly calculated MFT record size, causing undefined behavior when performing bit shifts with values that exceed type limits. The fix has been verified by executing the syzkaller reproducer test case. After applying this patch, the system successfully handles the test case without kernel panic or UBSAN warnings.

This approach is incorrect because, even if the PTE is a swap entry, it can still reference a folio that remains in the swap cache. This creates a race window between steps 2 and 4. 1. add_to_swap: The folio is added to the swapcache. 2. try_to_unmap: PTEs are converted to swap entries. 3. pageout: The folio is written back. 4. Swapcache is cleared. If userfaultfd_move() occurs in the window between steps 2 and 4, after the swap PTE has been moved to the destination, accessing the destination triggers do_swap_page(), which may locate the folio in the swapcache. However, since the folio's index has not been updated to match the destination VMA, do_swap_page() will detect a mismatch. This can result in two critical issues depending on the system configuration. If KSM is disabled, both small and large folios can trigger a BUG during the add_rmap operation due to: page_pgoff(folio, page) != linear_page_index(vma, address) [ 13.336953] page: refcount:6 mapcount:1 mapping:00000000f43db19c index:0xffffaf150 pfn:0x4667c [ 13.337520] head: order:2 mapcount:1 entire_mapcount:0 nr_pages_mapped:1 pincount:0 [ 13.337716] memcg:ffff00000405f000 [ 13.337849] anon flags: 0x3fffc0000020459(locked|uptodate|dirty|owner_priv_1|head|swapbacked|node=0|zone=0|lastcpupid=0xffff) [ 13.338630] raw: 03fffc0000020459 ffff80008507b538 ffff80008507b538 ffff000006260361 [ 13.338831] raw: 0000000ffffaf150 0000000000004000 0000000600000000 ffff00000405f000 [ 13.339031] head: 03fffc0000020459 ffff80008507b538 ffff80008507b538 ffff000006260361 [ 13.339204] head: 0000000ffffaf150 0000000000004000 0000000600000000 ffff00000405f000 [ 13.339375] head: 03fffc0000000202 fffffdffc0199f01 ffffffff00000000 0000000000000001 [ 13.339546] head: 0000000000000004 0000000000000000 00000000ffffffff 0000000000000000 [ 13.339736] page dumped because: VM_BUG_ON_PAGE(page_pgoff(folio, page) != linear_page_index(vma, address)) [ 13.340190] ------------[ cut here ]------------ [ 13.340316] kernel BUG at mm/rmap.c:1380!

This patch also checks the swapcache when handling swap entries. If a match is found in the swapcache, it processes it similarly to a present PTE. However, there are some differences. For example, the folio is no longer exclusive because folio_try_share_anon_rmap_pte() is performed during unmapping. Furthermore, in the case of swapcache, the folio has already been unmapped, eliminating the risk of concurrent rmap walks and removing the need to acquire src_folio's anon_vma or lock. Note that for large folios, in the swapcache handling path, we directly return -EBUSY since split_folio() will return -EBUSY regardless if the folio is under writeback or unmapped. This is not an urgent issue, so a follow-up patch may address it separately.

[PATCH 6.1.y 1/1] hrtimer: Use and report correct timerslack values for realtime tasks

by Felix Moessbauer

commit ed4fb6d7ef68111bb539283561953e5c6e9a6e38 upstream. The timerslack_ns setting is used to specify how much the hardware timers should be delayed, to potentially dispatch multiple timers in a single interrupt. This is a performance optimization. Timers of realtime tasks (having a realtime scheduling policy) should not be delayed. This logic was inconsitently applied to the hrtimers, leading to delays of realtime tasks which used timed waits for events (e.g. condition variables). Due to the downstream override of the slack for rt tasks, the procfs reported incorrect (non-zero) timerslack_ns values. This is changed by setting the timer_slack_ns task attribute to 0 for all tasks with a rt policy. By that, downstream users do not need to specially handle rt tasks (w.r.t. the slack), and the procfs entry shows the correct value of "0".

[PATCH 5.4 0/4] sctp: sysctl: fix argument passed to container_of

by Magali Lemes

Patches "sctp: sysctl: cookie_hmac_alg: avoid using current->nsproxy" and "sctp: sysctl: auth_enable: avoid using current->nsproxy" have been mixed up when backported to 5.4. The `member` argument passed to `container_of` has been swapped in both proc_sctp_do_auth() and proc_sctp_do_hmac_alg(). For instance, accessing /proc/sys/net/sctp/cookie_hmac_alg can now cause a kernel oops. Fix this by reverting the wrong backports and re-applying them correctly.

[PATCH 6.6.y 1/1] hrtimer: Use and report correct timerslack values for realtime tasks

by Felix Moessbauer

commit ed4fb6d7ef68111bb539283561953e5c6e9a6e38 upstream. The timerslack_ns setting is used to specify how much the hardware timers should be delayed, to potentially dispatch multiple timers in a single interrupt. This is a performance optimization. Timers of realtime tasks (having a realtime scheduling policy) should not be delayed. This logic was inconsitently applied to the hrtimers, leading to delays of realtime tasks which used timed waits for events (e.g. condition variables). Due to the downstream override of the slack for rt tasks, the procfs reported incorrect (non-zero) timerslack_ns values. This is changed by setting the timer_slack_ns task attribute to 0 for all tasks with a rt policy. By that, downstream users do not need to specially handle rt tasks (w.r.t. the slack), and the procfs entry shows the correct value of "0". Setting non-zero slack values (either via procfs or PR_SET_TIMERSLACK) on tasks with a rt policy is ignored, as stated in "man 2 PR_SET_TIMERSLACK": Timer slack is not applied to threads that are scheduled under a real-time scheduling policy (see sched_setscheduler(2)). The special handling of timerslack on rt tasks in downstream users is removed as well.

[PATCH v2] x86/microcode/AMD: Fix out-of-bounds on systems with CPU-less NUMA nodes

by Florent Revest

Currently, load_microcode_amd() iterates over all NUMA nodes, retrieves their CPU masks and unconditonally accesses per-CPU data for the first CPU of each mask. According to Documentation/admin-guide/mm/numaperf.rst: "Some memory may share the same node as a CPU, and others are provided as memory only nodes." Therefore, some node CPU masks may be empty and wouldn't have a "first CPU". On a machine with far memory (and therefore CPU-less NUMA nodes): - cpumask_of_node(nid) is 0 - cpumask_first(0) is CONFIG_NR_CPUS - cpu_data(CONFIG_NR_CPUS) accesses the cpu_info per-CPU array at an index that is 1 out of bounds This does not have any security implications since flashing microcode is a privileged operation but I believe this has reliability implications by potentially corrupting memory while flashing a microcode update. When booting with CONFIG_UBSAN_BOUNDS=y on an AMD machine that flashes a microcode update. I get the following splat: UBSAN: array-index-out-of-bounds in arch/x86/kernel/cpu/microcode/amd.c:X:Y index 512 is out of range for type 'unsigned long[512]' [...] Call Trace: dump_stack+0xdb/0x143 __ubsan_handle_out_of_bounds+0xf5/0x120 load_microcode_amd+0x58f/0x6b0 request_microcode_amd+0x17c/0x250 reload_store+0x174/0x2b0 kernfs_fop_write_iter+0x227/0x2d0 vfs_write+0x322/0x510 ksys_write+0xb5/0x160 do_syscall_64+0x6b/0xa0 entry_SYSCALL_64_after_hwframe+0x67/0xd1 This changes the iteration to only loop on NUMA nodes which have CPUs before attempting to update their microcodes.

It also appears that if the prefetched TRBs belong to a different ring whose doorbell is later rung, they may be used without refreshing from system RAM and the endpoint will stay idle if their cycle bit is stale. Other users complain about IOMMU faults on x86 systems, unsurprisingly. Deal with it by using existing quirk which allocates a dummy page after each transfer ring segment. This was seen to resolve both problems. RPi came up with a more efficient solution, shortening each segment by four TRBs, but it complicated the driver and they ditched it for this quirk. Also rename the quirk and add VL805 device ID macro.

This approach is incorrect because, even if the PTE is a swap entry, it can still reference a folio that remains in the swap cache. This creates a race window between steps 2 and 4. 1. add_to_swap: The folio is added to the swapcache. 2. try_to_unmap: PTEs are converted to swap entries. 3. pageout: The folio is written back. 4. Swapcache is cleared. If userfaultfd_move() occurs in the window between steps 2 and 4, after the swap PTE has been moved to the destination, accessing the destination triggers do_swap_page(), which may locate the folio in the swapcache. However, since the folio's index has not been updated to match the destination VMA, do_swap_page() will detect a mismatch. This can result in two critical issues depending on the system configuration.

This patch also checks the swapcache when handling swap entries. If a match is found in the swapcache, it processes it similarly to a present PTE. However, there are some differences. For example, the folio is no longer exclusive because folio_try_share_anon_rmap_pte() is performed during unmapping. Furthermore, in the case of swapcache, the folio has already been unmapped, eliminating the risk of concurrent rmap walks and removing the need to acquire src_folio's anon_vma or lock. Note that for large folios, in the swapcache handling path, we directly return -EBUSY since split_folio() will return -EBUSY regardless if the folio is under writeback or unmapped. This is not an urgent issue, so a follow-up patch may address it separately.

[PATCH 0/2] ARM: Fix ARM_VECTORS with CONFIG_LD_DEAD_CODE_DATA_ELIMINATION

by Nathan Chancellor

Hi all, Christian sent a fix [1] for ARM_VECTORS with CONFIG_LD_DEAD_CODE_DATA_ELIMINATION that exposed a deficiency in ld.lld with regards to KEEP() within an OVERLAY description. I have fixed that in ld.lld [2] and added a patch before Christian's to disallow CONFIG_LD_DEAD_CODE_DATA_ELIMINATION when KEEP() cannot be used within OVERLAY to keep everything working for all linkers.

[PATCH v2 1/2] regulator: dummy: force synchronous probing

by Christian Eggers

Sometimes I get a NULL pointer dereference at boot time in kobject_get() with the following call stack: anatop_regulator_probe() devm_regulator_register() regulator_register() regulator_resolve_supply() kobject_get() By placing some extra BUG_ON() statements I could verify that this is raised because probing of the 'dummy' regulator driver is not completed ('dummy_regulator_rdev' is still NULL). In the JTAG debugger I can see that dummy_regulator_probe() and anatop_regulator_probe() can be run by different kernel threads (kworker/u4:*). I haven't further investigated whether this can be changed or if there are other possibilities to force synchronization between these two probe routines. On the other hand I don't expect much boot time penalty by probing the 'dummy' regulator synchronously.

This was overkill because it's not an urgent problem that no core is on the verge of consuming that bad data. It's also found that multi SRAO UCE may cause nested MCE interrupts and finally become an IERR. Hence, Intel downgrades the machine check bank signature of patrol scrub from SRAO to UCNA (Uncorrected, No Action required), and signal changed to #CMCI. Just to add to the confusion, Linux does take an action (in uc_decode_notifier()) to try to offline the page despite the UC*NA* signature name. - Background: why #CMCI and #MCE race when poison is consuming in Intel platform [1] Having decided that CMCI/UCNA is the best action for patrol scrub errors, the memory controller uses it for reads too. But the memory controller is executing asynchronously from the core, and can't tell the difference between a "real" read and a speculative read. So it will do CMCI/UCNA if an error is found in any read. Thus: 1) Core is clever and thinks address A is needed soon, issues a speculative read. 2) Core finds it is going to use address A soon after sending the read request 3) The CMCI from the memory controller is in a race with MCE from the core that will soon try to retire the load from address A. Quite often (because speculation has got better) the CMCI from the memory controller is delivered before the core is committed to the instruction reading address A, so the interrupt is taken, and Linux offlines the page (marking it as poison). - Why user process is killed for instr case Commit 046545a661af ("mm/hwpoison: fix error page recovered but reported "not recovered"") tries to fix noise message "Memory error not recovered" and skips duplicate SIGBUSs due to the race. But it also introduced a bug that kill_accessing_process() return -EHWPOISON for instr case, as result, kill_me_maybe() send a SIGBUS to user process. If the CMCI wins that race, the page is marked poisoned when uc_decode_notifier() calls memory_failure(). For dirty pages, memory_failure() invokes try_to_unmap() with the TTU_HWPOISON flag, converting the PTE to a hwpoison entry. As a result, kill_accessing_process(): - call walk_page_range() and return 1 regardless of whether try_to_unmap() succeeds or fails, - call kill_proc() to make sure a SIGBUS is sent - return -EHWPOISON to indicate that SIGBUS is already sent to the process and kill_me_maybe() doesn't have to send it again. However, for clean pages, the TTU_HWPOISON flag is cleared, leaving the PTE unchanged and not converted to a hwpoison entry. Conversely, for clean pages where PTE entries are not marked as hwpoison, kill_accessing_process() returns -EFAULT, causing kill_me_maybe() to send a SIGBUS. Console log looks like this: Memory failure: 0x827ca68: corrupted page was clean: dropped without side effects Memory failure: 0x827ca68: recovery action for clean LRU page: Recovered Memory failure: 0x827ca68: already hardware poisoned mce: Memory error not recovered To fix it, return 0 for "corrupted page was clean", preventing an unnecessary SIGBUS to user process.

What am I trying to do: This patchset resolves two critical regressions related to memory failure handling that have appeared in the upstream kernel since version 5.17, as compared to 5.10 LTS. - copyin case: poison found in user page while kernel copying from user space - instr case: poison found while instruction fetching in user space ## 2. What is the expected outcome and why - For copyin case: Kernel can recover from poison found where kernel is doing get_user() or copy_from_user() if those places get an error return and the kernel return -EFAULT to the process instead of crashing. More specifily, MCE handler checks the fixup handler type to decide whether an in kernel #MC can be recovered. When EX_TYPE_UACCESS is found, the PC jumps to recovery code specified in _ASM_EXTABLE_FAULT() and return a -EFAULT to user space. - For instr case: If a poison found while instruction fetching in user space, full recovery is possible. User process takes #PF, Linux allocates a new page and fills by reading from storage. ## 3. What actually happens and why - For copyin case: kernel panic since v5.17 Commit 4c132d1d844a ("x86/futex: Remove .fixup usage") introduced a new extable fixup type, EX_TYPE_EFAULT_REG, and later patches updated the extable fixup type for copy-from-user operations, changing it from EX_TYPE_UACCESS to EX_TYPE_EFAULT_REG. It breaks previous EX_TYPE_UACCESS handling when posion found in get_user() or copy_from_user(). - For instr case: user process is killed by a SIGBUS signal due to #CMCI and #MCE race When an uncorrected memory error is consumed there is a race between the CMCI from the memory controller reporting an uncorrected error with a UCNA signature, and the core reporting and SRAR signature machine check when the data is about to be consumed. ### Background: why *UN*corrected errors tied to *C*MCI in Intel platform [1] Prior to Icelake memory controllers reported patrol scrub events that detected a previously unseen uncorrected error in memory by signaling a broadcast machine check with an SRAO (Software Recoverable Action Optional) signature in the machine check bank. This was overkill because it's not an urgent problem that no core is on the verge of consuming that bad data. It's also found that multi SRAO UCE may cause nested MCE interrupts and finally become an IERR. Hence, Intel downgrades the machine check bank signature of patrol scrub from SRAO to UCNA (Uncorrected, No Action required), and signal changed to #CMCI. Just to add to the confusion, Linux does take an action (in uc_decode_notifier()) to try to offline the page despite the UC*NA* signature name. ### Background: why #CMCI and #MCE race when poison is consuming in Intel platform [1] Having decided that CMCI/UCNA is the best action for patrol scrub errors, the memory controller uses it for reads too. But the memory controller is executing asynchronously from the core, and can't tell the difference between a "real" read and a speculative read. So it will do CMCI/UCNA if an error is found in any read. Thus: 1) Core is clever and thinks address A is needed soon, issues a speculative read. 2) Core finds it is going to use address A soon after sending the read request 3) The CMCI from the memory controller is in a race with MCE from the core that will soon try to retire the load from address A. Quite often (because speculation has got better) the CMCI from the memory controller is delivered before the core is committed to the instruction reading address A, so the interrupt is taken, and Linux offlines the page (marking it as poison). ## Why user process is killed for instr case Commit 046545a661af ("mm/hwpoison: fix error page recovered but reported "not recovered"") tries to fix noise message "Memory error not recovered" and skips duplicate SIGBUSs due to the race. But it also introduced a bug that kill_accessing_process() return -EHWPOISON for instr case, as result, kill_me_maybe() send a SIGBUS to user process. # 4. The fix, in my opinion, should be: - For copyin case: The key point is whether the error context is in a read from user memory. We do not care about the ex-type if we know its a MOV reading from userspace. is_copy_from_user() return true when both of the following two checks are true: - the current instruction is copy - source address is user memory If copy_user is true, we set m->kflags |= MCE_IN_KERNEL_COPYIN | MCE_IN_KERNEL_RECOV; Then do_machine_check() will try fixup_exception() first. - For instr case: let kill_accessing_process() return 0 to prevent a SIGBUS. - For patch 3: The return value of memory_failure() is quite important while discussed instr case regression with Tony and Miaohe for patch 2, so add comment about the return value. This patch (of 3): Commit 4c132d1d844a ("x86/futex: Remove .fixup usage") introduced a new extable fixup type, EX_TYPE_EFAULT_REG, and commit 4c132d1d844a ("x86/futex: Remove .fixup usage") updated the extable fixup type for copy-from-user operations, changing it from EX_TYPE_UACCESS to EX_TYPE_EFAULT_REG. The error context for copy-from-user operations no longer functions as an in-kernel recovery context. Consequently, the error context for copy-from-user operations no longer functions as an in-kernel recovery context, resulting in kernel panics with the message: "Machine check: Data load in unrecoverable area of kernel." To address this, it is crucial to identify if an error context involves a read operation from user memory. The function is_copy_from_user() can be utilized to determine: - the current operation is copy - when reading user memory When these conditions are met, is_copy_from_user() will return true, confirming that it is indeed a direct copy from user memory. This check is essential for correctly handling the context of errors in these operations without relying on the extable fixup types that previously allowed for in-kernel recovery.

It is "locked" with a test_and_set_bit (similarly to a try lock) which provides full ordering with respect to loads and stores done within __node_reclaim(). It is "unlocked" with clear_bit(), which does not provide any ordering with respect to loads and stores done before clearing the bit. The lack of clear_bit() memory ordering with respect to stores within __node_reclaim() can cause a subsequent CPU to fail to observe stores from a prior node reclaim. This is not an issue in practice on TSO (e.g. x86), but it is an issue on weakly-ordered architectures (e.g. arm64). Fix this by using clear_bit_unlock rather than clear_bit to clear PGDAT_RECLAIM_LOCKED with a release memory ordering semantic. This provides stronger memory ordering (release rather than relaxed).

This problem was initially reported by Dimitris Siakavaras in July 2023 [1] in a firecracker use case. Firecracker has a separate process handling page faults remotely, and when the process releases the userfaultfd it can race with a concurrent GUP from KVM trying to fault in a guest page during the secondary MMU page fault process. A similar problem was reported recently again by Jinjiang Tu in March 2025 [2], even though the race happened this time with a mlockall() operation, which does GUP in a similar fashion. In 2017, commit 656710a60e36 ("userfaultfd: non-cooperative: closing the uffd without triggering SIGBUS") was trying to fix this issue. AFAIU, that fixes well the fault paths but may not work yet for GUP. In GUP, the issue is NOPAGE will be almost treated the same as "page fault resolved" in faultin_page(), then the GUP will follow page again, seeing page missing, and it'll keep going into a live lock situation as reported. This change makes core mm return RETRY instead of NOPAGE for both the GUP and fault paths, proactively releasing the mmap read lock. This should guarantee the other release thread make progress on taking the write lock and avoid the live lock even for GUP. When at it, rearrange the comments to make sure it's uptodate.

[PATCH v3] svc-i3c-master: Fix read from unreadable memory at svc_i3c_master_ibi_work

by Manjunatha Venkatesh

As part of I3C driver probing sequence for particular device instance, While adding to queue it is trying to access ibi variable of dev which is not yet initialized causing "Unable to handle kernel read from unreadable memory" resulting in kernel panic. Below is the sequence where this issue happened. 1. During boot up sequence IBI is received at host from the slave device before requesting for IBI, Usually will request IBI by calling i3c_device_request_ibi() during probe of slave driver. 2. Since master code trying to access IBI Variable for the particular device instance before actually it initialized by slave driver, due to this randomly accessing the address and causing kernel panic. 3. i3c_device_request_ibi() function invoked by the slave driver where dev->ibi = ibi; assigned as part of function call i3c_dev_request_ibi_locked(). 4. But when IBI request sent by slave device, master code trying to access this variable before its initialized due to this race condition situation kernel panic happened. fixes: dd3c52846d595 (i3c: master: svc: Add Silvaco I3C master driver) Cc: stable(a)vger.kernel.org Signed-off-by: Manjunatha Venkatesh <manjunatha.venkatesh(a)nxp.com> --- Changes since v2: - Description updated as per the review feedback drivers/i3c/master/svc-i3c-master.c | 7 +++++-- 1 file changed, 5 insertions(+), 2 deletions(-) diff --git a/drivers/i3c/master/svc-i3c-master.c b/drivers/i3c/master/svc-i3c-master.c index d6057d8c7dec..98c4d2e5cd8d 100644 --- a/drivers/i3c/master/svc-i3c-master.c +++ b/drivers/i3c/master/svc-i3c-master.c @@ -534,8 +534,11 @@ static void svc_i3c_master_ibi_work(struct work_struct *work) switch (ibitype) { case SVC_I3C_MSTATUS_IBITYPE_IBI: if (dev) { - i3c_master_queue_ibi(dev, master->ibi.tbq_slot); - master->ibi.tbq_slot = NULL; + data = i3c_dev_get_master_data(dev); + if (master->ibi.slots[data->ibi]) { + i3c_master_queue_ibi(dev, master->ibi.tbq_slot); + master->ibi.tbq_slot = NULL; + } } svc_i3c_master_emit_stop(master); break; -- 2.46.1

[PATCH 1/3] mm/memblock: pass size instead of end to memblock_set_node()

[PATCH v4 0/4] samsung: pinctrl: Add support for eint_fltcon_offset and filter selection on gs101

by Peter Griffin

Hi folks, This series fixes support for correctly saving and restoring fltcon0 and fltcon1 registers on gs101 for non-alive banks where the fltcon register offset is not at a fixed offset (unlike previous SoCs). This is done by adding a eint_fltcon_offset and providing GS101 specific pin macros that take an additional parameter (similar to how exynosautov920 handles it's eint_con_offset). Additionally the SoC specific suspend and resume callbacks are re-factored so that each SoC variant has it's own callback containing the peculiarities for that SoC. Finally support for filter selection on alive banks is added, this is currently only enabled for gs101. The code path can be excercised using `echo mem > /sys/power/state` regards, Peter To: Krzysztof Kozlowski <krzk(a)kernel.org> To: Sylwester Nawrocki <s.nawrocki(a)samsung.com> To: Alim Akhtar <alim.akhtar(a)samsung.com> To: Linus Walleij <linus.walleij(a)linaro.org> Cc: linux-arm-kernel(a)lists.infradead.org Cc: linux-samsung-soc(a)vger.kernel.org Cc: linux-gpio(a)vger.kernel.org Cc: linux-kernel(a)vger.kernel.org Cc: andre.draszik(a)linaro.org Cc: tudor.ambarus(a)linaro.org Cc: willmcvicker(a)google.com Cc: semen.protsenko(a)linaro.org Cc: kernel-team(a)android.com Cc: jaewon02.kim(a)samsung.com Signed-off-by: Peter Griffin <peter.griffin(a)linaro.org> --- Changes in v4: - save->eint_fltcon1 is an argument to pr_debug(), not readl() change alignment accordingly (Andre) - Link to v3: https://lore.kernel.org/r/20250306-pinctrl-fltcon-suspend-v3-0-f9ab4ff6a24e… Changes in v3: - Ensure EXYNOS_FLTCON_DIGITAL bit is cleared (Andre) - Make it obvious that exynos_eint_set_filter() is conditional on bank type (Andre) - Make it obvious exynos_set_wakeup() is conditional on bank type (Andre) - Align style where the '+' is placed first (Andre) - Remove unnecessary braces (Andre) - Link to v2: https://lore.kernel.org/r/20250301-pinctrl-fltcon-suspend-v2-0-a7eef9bb443b… Changes in v2: - Remove eint_flt_selectable bool as it can be deduced from EINT_TYPE_WKUP (Peter) - Move filter config register comment to header file (Andre) - Rename EXYNOS_FLTCON_DELAY to EXYNOS_FLTCON_ANALOG (Andre) - Remove misleading old comment (Andre) - Refactor exynos_eint_update_flt_reg() into a loop (Andre) - Split refactor of suspend/resume callbacks & gs101 parts into separate patches (Andre) - Link to v1: https://lore.kernel.org/r/20250120-pinctrl-fltcon-suspend-v1-0-e77900b2a854… --- Peter Griffin (4): pinctrl: samsung: add support for eint_fltcon_offset pinctrl: samsung: add dedicated SoC eint suspend/resume callbacks pinctrl: samsung: add gs101 specific eint suspend/resume callbacks pinctrl: samsung: Add filter selection support for alive bank on gs101 drivers/pinctrl/samsung/pinctrl-exynos-arm64.c | 150 ++++++------- drivers/pinctrl/samsung/pinctrl-exynos.c | 294 +++++++++++++++---------- drivers/pinctrl/samsung/pinctrl-exynos.h | 50 ++++- drivers/pinctrl/samsung/pinctrl-samsung.c | 12 +- drivers/pinctrl/samsung/pinctrl-samsung.h | 12 +- 5 files changed, 318 insertions(+), 200 deletions(-) --- base-commit: 0761652a3b3b607787aebc386d412b1d0ae8008c change-id: 20250120-pinctrl-fltcon-suspend-2333a137c4d4 Best regards, -- Peter Griffin <peter.griffin(a)linaro.org>

[PATCH v3 0/6] KVM: arm64: PMU: Fix SET_ONE_REG for vPMC regs

by Akihiko Odaki

Prepare vPMC registers for user-initiated changes after first run. This is important specifically for debugging Windows on QEMU with GDB; QEMU tries to write back all visible registers when resuming the VM execution with GDB, corrupting the PMU state. Windows always uses the PMU so this can cause adverse effects on that particular OS.

[PATCH] usb: typec: tcpm: fix state transition for SNK_WAIT_CAPABILITIES state in run_state_machine()

by Amit Sunil Dhamne via B4 Relay

From: Amit Sunil Dhamne <amitsd(a)google.com> A subtle error got introduced while manually fixing merge conflict in tcpm.c for commit 85c4efbe6088 ("Merge v6.12-rc6 into usb-next"). As a result of this error, the next state is unconditionally set to SNK_WAIT_CAPABILITIES_TIMEOUT while handling SNK_WAIT_CAPABILITIES state in run_state_machine(...). Fix this by setting new state of TCPM state machine to `upcoming_state` (that is set to different values based on conditions).

[PATCH v3 0/7] drm/v3d: Fix GPU reset issues on the Raspberry Pi 5

by Maíra Canal

This series addresses GPU reset issues reported in [1], where running a long compute job would trigger repeated GPU resets, leading to a UI freeze. Patches #1 and #2 prevent the same faulty job from being resubmitted in a loop, mitigating the first cause of the issue. However, the issue isn't entirely solved. Even with only a single GPU reset, the UI still freezes on the Raspberry Pi 5, indicating a GPU hang. Patches #3 to #6 address this by properly configuring the V3D_SMS registers, which are required for power management and resets in V3D 7.1. Patch #7 updates the DT maintainership, replacing Emma with the current v3d driver maintainer.

[PATCH v5 01/16] x86/stackprotector: Work around strict Clang TLS symbol requirements

by Brian Gerst

From: Ard Biesheuvel <ardb(a)kernel.org> GCC and Clang both implement stack protector support based on Thread Local Storage (TLS) variables, and this is used in the kernel to implement per-task stack cookies, by copying a task's stack cookie into a per-CPU variable every time it is scheduled in. Both now also implement -mstack-protector-guard-symbol=, which permits the TLS variable to be specified directly. This is useful because it will allow us to move away from using a fixed offset of 40 bytes into the per-CPU area on x86_64, which requires a lot of special handling in the per-CPU code and the runtime relocation code. However, while GCC is rather lax in its implementation of this command line option, Clang actually requires that the provided symbol name refers to a TLS variable (i.e., one declared with __thread), although it also permits the variable to be undeclared entirely, in which case it will use an implicit declaration of the right type. The upshot of this is that Clang will emit the correct references to the stack cookie variable in most cases, e.g., 10d: 64 a1 00 00 00 00 mov %fs:0x0,%eax 10f: R_386_32 __stack_chk_guard However, if a non-TLS definition of the symbol in question is visible in the same compilation unit (which amounts to the whole of vmlinux if LTO is enabled), it will drop the per-CPU prefix and emit a load from a bogus address. Work around this by using a symbol name that never occurs in C code, and emit it as an alias in the linker script.

[PATCH v3 1/2] PCI: Fix wrong length of devres array

by Philipp Stanner

The array for the iomapping cookie addresses has a length of PCI_STD_NUM_BARS. This constant, however, only describes standard BARs; while PCI can allow for additional, special BARs. The total number of PCI resources is described by constant PCI_NUM_RESOURCES, which is also used in, e.g., pci_select_bars(). Thus, the devres array has so far been too small. Change the length of the devres array to PCI_NUM_RESOURCES.

[PATCH 07/11] drm/amd/display: Use HW lock mgr for PSR1 when only one eDP

by Alex Hung

From: Mario Limonciello <mario.limonciello(a)amd.com> [WHY] DMUB locking is important to make sure that registers aren't accessed while in PSR. Previously it was enabled but caused a deadlock in situations with multiple eDP panels. [HOW] Detect if multiple eDP panels are in use to decide whether to use lock. Refactor the function so that the first check is for PSR-SU and then replay is in use to prevent having to look up number of eDP panels for those configurations.

The include/linux/pgalloc.h is going to be the home of generic page table population functions. Start with including asm/pgalloc.h to include/linux/pgalloc.h and adding functions that if an architecture needs to synchronize global pgds when populating the init_mm's pgd. The newly introduced p4d_populate_kernel() and pgd_populate_kernel() functions synchronize global pgds after populating init_mm's p4d/pgd. If the architecture requires to synchronize global pgds, add ARCH_USE_SYNC_GLOBAL_PGDS to the Kconfig of the required architecture and implement arch_sync_global_p4ds() and arch_sync_global_pgds() to the architecture. And this patch adds an implementation to the x86 architecture. Through using new introduced p4d_populate_kernel() and pgd_populate_kernel() functions, it addresses an Oops issues when performing test of loading XE GPU driver module after applying the GPU SVM and Xe SVM patch series[1] and the Dept patch series[2]. The issue occurs when loading the xe driver via modprobe [3], which adds a struct page for device memory via devm_memremap_pages(). When a process leads the addition of a struct page to vmemmap (e.g. hot-plug), the page table update for the newly added vmemmap-based virtual address is updated first in init_mm's page table and then synchronized later. If the vmemmap-based virtual address is accessed through the process's page table before this sync, a page fault will occur. This addresses the issue by synchronizing with the global pgds immediately after populating the init_mm's pgd.

Until then, all watermarks are set to zero. This causes cond_accept_memory() to incorrectly skip memory acceptance because a watermark of 0 is always met. This can lead to a premature OOM on boot.

[PATCH] kbuild: deb-pkg: don't set KBUILD_BUILD_VERSION indiscriminately

by Alexandru Gagniuc

In ThinPro, we use the convention <upstream_ver>+hp<patchlevel> for the kernel package. This does not have a dash in the name or version. This is built by editing ".version" before a build, and setting EXTRAVERSION="+hp" and KDEB_PKGVERSION make variables: echo 68 > .version make -j<n> EXTRAVERSION="+hp" bindeb-pkg KDEB_PKGVERSION=6.6.6+hp69 .deb name: linux-image-6.6.6+hp_6.6.6+hp69_amd64.deb Since commit 7d4f07d5cb71 ("kbuild: deb-pkg: squash scripts/package/deb-build-option to debian/rules"), this no longer works. The deb build logic changed, even though, the commit message implies that the logic should be unmodified. Before, KBUILD_BUILD_VERSION was not set if the KDEB_PKGVERSION did not contain a dash. After the change KBUILD_BUILD_VERSION is always set to KDEB_PKGVERSION. Since this determines UTS_VERSION,the uname output to look off: (now) uname -a: version 6.6.6+hp ... #6.6.6+hp69 (expected) uname -a: version 6.6.6+hp ... #69 Update the debian/rules logic to restore the original behavior.

[PATCH] memcg: drain obj stock on cpu hotplug teardown

by Shakeel Butt

Currently on cpu hotplug teardown, only memcg stock is drained but we need to drain the obj stock as well otherwise we will miss the stats accumulated on the target cpu as well as the nr_bytes cached. The stats include MEMCG_KMEM, NR_SLAB_RECLAIMABLE_B & NR_SLAB_UNRECLAIMABLE_B. In addition we are leaking reference to struct obj_cgroup object.

[PATCH v2] kbuild: exclude .rodata.(cst|str)* when building ranges

by Kris Van Hees

The .rodata.(cst|str)* sections are often resized during the final linking and since these sections do not cover actual symbols there is no need to include them in the modules.builtin.ranges data. When these sections were included in processing and resizing occurred, modules were reported with ranges that extended beyond their true end, causing subsequent symbols (in address order) to be associated with the wrong module.

[PATCH 6.1.y] selftests/vm: fix undefined reference of the `default_huge_page_size`

by Andrey Kalachev

The commit a584c7734a4d ("selftests: mm: fix map_hugetlb failure on 64K page size systems") backported the fix from v6.8 to stable v6.1. The patch uses default_huge_page_size() function, which definition moved into vm_util.[ch] by commit bd4d67e76f699 ("selftests/mm: merge default_huge_page_size() into one") merged to upsream since v6.4. However, in v6.1 common definition/declaration for the default_huge_page_size() we doesn't have, the following build error is seen: map_hugetlb.c:79:25: warning: implicit declaration of function ‘default_huge_page_size’ [-Wimplicit-function-declaration] 79 | hugepage_size = default_huge_page_size(); | ^~~~~~~~~~~~~~~~~~~~~~ /usr/bin/ld: /tmp/ccx95BZz.o: in function `main': map_hugetlb.c:(.text+0x104): undefined reference to `default_huge_page_size' Place default_huge_page_size() function body into map_hugetlb.c to fix this issue.

[PATCH] fpga: bridge: incorrect set to clear freeze_illegal_request register

by Tanmay Kathpalia

A Partial Region Controller can be connected to one or more Freeze Bridge. Each Freeze Bridge has an illegal_request bit represented in the freeze_illegal_request register. Thus, instead of just set to clear the illegal_request bit for first Freeze Bridge, we need to ensure the set to clear action is applied to which ever Freeze Bridge that has occurrence of illegal request.

On our board, the 0002:00:07.0 bridge is misconfigured by the bootloader. Both its secondary and subordinate bus numbers are initialized to 0, while its fixed secondary bus number is set to 8. However, bus number 8 is also assigned to another bridge (0002:00:0f.0). Although this is a bootloader issue, before the change in commit 7246a4520b4b, the PCI_REASSIGN_ALL_BUS flag was set by default when PCI_PROBE_ONLY was not enabled, ensuing that all the bus number for these bridges were reassigned, avoiding any conflicts. After the change introduced in commit 7246a4520b4b, the bus numbers assigned by the bootloader are reused by all other bridges, except the misconfigured 0002:00:07.0 bridge. The kernel attempt to reconfigure 0002:00:07.0 by reusing the fixed secondary bus number 8 assigned by bootloader. However, since a pci_bus has already been allocated for bus 8 due to the probe of 0002:00:0f.0, no new pci_bus allocated for 0002:00:07.0. This results in a pci bridge device without a pci_bus attached (pdev->subordinate == NULL). Consequently, accessing pdev->subordinate in of_pci_prop_bus_range() leads to a NULL pointer dereference. To summarize, we need to set the PCI_REASSIGN_ALL_BUS flag when PCI_PROBE_ONLY is not enabled in order to work around issue like the one described above.

[PATCH v9] arm64: mm: Populate vmemmap at the page level if not section aligned

by Zhenhua Huang

On the arm64 platform with 4K base page config, SECTION_SIZE_BITS is set to 27, making one section 128M. The related page struct which vmemmap points to is 2M then. Commit c1cc1552616d ("arm64: MMU initialisation") optimizes the vmemmap to populate at the PMD section level which was suitable initially since hot plug granule is always one section(128M). However, commit ba72b4c8cf60 ("mm/sparsemem: support sub-section hotplug") introduced a 2M(SUBSECTION_SIZE) hot plug granule, which disrupted the existing arm64 assumptions. The first problem is that if start or end is not aligned to a section boundary, such as when a subsection is hot added, populating the entire section is wasteful. The next problem is if we hotplug something that spans part of 128 MiB section (subsections, let's call it memblock1), and then hotplug something that spans another part of a 128 MiB section(subsections, let's call it memblock2), and subsequently unplug memblock1, vmemmap_free() will clear the entire PMD entry which also supports memblock2 even though memblock2 is still active. Assuming hotplug/unplug sizes are guaranteed to be symmetric. Do the fix similar to x86-64: populate to pages levels if start/end is not aligned with section boundary.

[PATCH] media: ov08x40: Extend sleep after reset to 5 ms

by Hans de Goede

Some users are reporting that ov08x40_identify_module() fails to identify the chip reading 0x00 as value for OV08X40_REG_CHIP_ID. Intel's out of tree IPU6 drivers include some ov08x40 changes including adding support for the reset GPIO for older kernels and Intel's patch for this uses 5 ms. Extend the sleep to 5 ms following Intel's example, this fixes the ov08x40_identify_module() problem.

The existing mremap() logic has grown organically over a very long period of time, resulting in code that is in many parts, very difficult to follow and full of subtleties and sources of confusion. In addition, it is difficult to thread state through the operation correctly, as function arguments have expanded, some parameters are expected to be temporarily altered during the operation, others are intended to remain static and some can be overridden. This series completely refactors the mremap implementation, sensibly separating functions, adding comments to explain the more subtle aspects of the implementation and making use of small structs to thread state through everything. The reason for doing so is to lay the groundwork for planned future changes to the mremap logic, changes which require the ability to easily pass around state. Additionally, it would be unhelpful to add yet more logic to code that is already difficult to follow without first refactoring it like this. The first patch in this series additionally fixes a bug when a VMA with start address zero is partially remapped. Tested on real hardware under heavy workload and all self tests are passing. This patch (of 3): Consider the case of a partial mremap() (that results in a VMA split) of an accountable VMA (i.e. which has the VM_ACCOUNT flag set) whose start address is zero, with the MREMAP_MAYMOVE flag specified and a scenario where a move does in fact occur: addr end | | v v |-------------| | vma | |-------------| 0 This move is affected by unmapping the range [addr, end). In order to prevent an incorrect decrement of accounted memory which has already been determined, the mremap() code in move_vma() clears VM_ACCOUNT from the VMA prior to doing so, before reestablishing it in each of the VMAs post-split: addr end | | v v |---| |---| | A | | B | |---| |---| Commit 6b73cff239e5 ("mm: change munmap splitting order and move_vma()") changed this logic such as to determine whether there is a need to do so by establishing account_start and account_end and, in the instance where such an operation is required, assigning them to vma->vm_start and vma->vm_end. Later the code checks if the operation is required for 'A' referenced above thusly: if (account_start) { ... } However, if the VMA described above has vma->vm_start == 0, which is now assigned to account_start, this branch will not be executed. As a result, the VMA 'A' above will remain stripped of its VM_ACCOUNT flag, incorrectly. The fix is to simply convert these variables to booleans and set them as required.

[PATCH] drm/dp_mst: Fix locking when skipping CSN before topology probing

by Imre Deak

The handling of the MST Connection Status Notify message is skipped if the probing of the topology is still pending. Acquiring the drm_dp_mst_topology_mgr::probe_lock for this in drm_dp_mst_handle_up_req() is problematic: the task/work this function is called from is also responsible for handling MST down-request replies (in drm_dp_mst_handle_down_rep()). Thus drm_dp_mst_link_probe_work() - holding already probe_lock - could be blocked waiting for an MST down-request reply while drm_dp_mst_handle_up_req() is waiting for probe_lock while processing a CSN message. This leads to the probe work's down-request message timing out. A scenario similar to the above leading to a down-request timeout is handling a CSN message in drm_dp_mst_handle_conn_stat(), holding the probe_lock and sending down-request messages while a second CSN message sent by the sink subsequently is handled by drm_dp_mst_handle_up_req(). Fix the above by moving the logic to skip the CSN handling to drm_dp_mst_process_up_req(). This function is called from a work (separate from the task/work handling new up/down messages), already holding probe_lock. This solves the above timeout issue, since handling of down-request replies won't be blocked by probe_lock.

[5.4/5.10/5.15/6.1/6.6] spi-mxs: Fix chipselect glitch

by Stefan Wahren

Dear stable team, I noticed that ceeeb99cd821 ("dmaengine: mxs: rename custom flag") got backported, but the additional fix 269e31aecdd0 ("spi-mxs: Fix chipselect glitch") hasn't. I think was caused by the lack of Cc to stable. Without the latter patch the SPI is causing glitches on MXS platform. Please backport it from 5.4 to 6.6. Thanks Stefan

Sometimes I get a NULL pointer dereference at boot time in kobject_get() with the following call stack: anatop_regulator_probe() devm_regulator_register() regulator_register() regulator_resolve_supply() kobject_get() By placing some extra BUG_ON() statements I could verify that this is raised because probing of the 'dummy' regulator driver is not completed ('dummy_regulator_rdev' is still NULL). In the JTAG debugger I can see that dummy_regulator_probe() and anatop_regulator_probe() can be run by different kernel threads (kworker/u4:*). I haven't further investigated whether this can be changed or if there are other possibilities to force synchronization between these two probe routines. On the other hand I don't expect much boot time penalty by probing the 'dummy' regulator synchronously.

[PATCH 2/3] usb: chipidea: ci_hdrc_imx: disable regulator on error path in probe

by Fedor Pchelkin

Upon encountering errors during the HSIC pinctrl handling section the regulator should be disabled. After the above-stated changes it is possible to jump onto "disable_hsic_regulator" label without having added the CPU latency QoS request previously. This would result in cpu_latency_qos_remove_request() yielding a WARNING. So rearrange the error handling path to follow the reverse order of different probing phases.

[PATCH] mm/huge_memory: drop beyond-EOF folios with the right number of refs.

by Zi Yan

When an after-split folio is large and needs to be dropped due to EOF, folio_put_refs(folio, folio_nr_pages(folio)) should be used to drop all page cache refs. Otherwise, the folio will not be freed, causing memory leak. This leak would happen on a filesystem with blocksize > page_size and a truncate is performed, where the blocksize makes folios split to >0 order ones, causing truncated folios not being freed.

net: cadence: macb: Enable software IRQ coalescing by default

by Daniel J Blueman

The macb ethernet driver (Raspberry Pi 5) delivers interrupts only to the first core, quickly saturating it at higher packet rates. Introducing software interrupt coalescing dramatically alleviates this limitation; the oneliner fix is upstream at d57f7b45945ac0517ff8ea50655f00db6e8d637c. Please backport this fix to 6.6 -stable to bring this benefit to more Raspberry Pis; it applies cleanly on this branch. Many thanks, Daniel -- Daniel J Blueman

[PATCH v3 2/2] phy: freescale: imx8m-pcie: assert phy reset and perst in power off

by Stefan Eichenberger

From: Stefan Eichenberger <stefan.eichenberger(a)toradex.com> Ensure the PHY reset and perst is asserted during power-off to guarantee it is in a reset state upon repeated power-on calls. This resolves an issue where the PHY may not properly initialize during subsequent power-on cycles. Power-on will deassert the reset at the appropriate time after tuning the PHY parameters. During suspend/resume cycles, we observed that the PHY PLL failed to lock during resume when the CPU temperature increased from 65C to 75C. The observed errors were: phy phy-32f00000.pcie-phy.3: phy poweron failed --> -110 imx6q-pcie 33800000.pcie: waiting for PHY ready timeout! imx6q-pcie 33800000.pcie: PM: dpm_run_callback(): genpd_resume_noirq+0x0/0x80 returns -110 imx6q-pcie 33800000.pcie: PM: failed to resume noirq: error -110 This resulted in a complete CPU freeze, which is resolved by ensuring the PHY is in reset during power-on, thus preventing PHY PLL failures.

[PATCH net] net: mana: Support holes in device list reply msg

by Haiyang Zhang

According to GDMA protocol, holes (zeros) are allowed at the beginning or middle of the gdma_list_devices_resp message. The existing code cannot properly handle this, and may miss some devices in the list. To fix, scan the entire list until the num_of_devs are found, or until the end of the list.

Provide for this by adding an `unsigned long sz` parameter to the function. This follows the same pattern as huge_pte_clear() and set_huge_pte_at(). This commit makes the required interface modifications to the core mm as well as all arches that implement this function (arm64, loongarch, mips, parisc, powerpc, riscv, s390, sparc). The actual arm64 bug will be fixed in a separate commit.

The driver_override_store() function uses driver_set_override() to update the driver_override value, and driver_set_override() internally locks the device (device_lock(dev)).

Additionally, a similar pattern is used in drivers/amba/bus.c, as well as many other bus drivers, where device_lock() is taken in the show function, and it has been working without issues.

These functions can be executed concurrently in sysfs. The driver_override_store() function uses driver_set_override() to update the driver_override value, and driver_set_override() internally locks the device (device_lock(dev)). If driver_override_show() reads cdx_dev->driver_override without locking, it could potentially access a freed pointer if driver_override_store() frees the string concurrently. This could lead to printing a kernel address, which is a security risk since DEVICE_ATTR can be read by all users.

AMD CPUs have a quirk (some would say "bug"), where the STI shadow bleeds into the guest's intr_state field if a #VMEXIT occurs during injection of an event, i.e. if the VMRUN doesn't complete before the subsequent #VMEXIT. The spurious "interrupts masked" state is relatively benign, as it only occurs during event injection and is transient. Because KVM is already injecting an event, the guest can't be in HLT, and if KVM is querying IRQ blocking for injection, then KVM would need to force an immediate exit anyways since injecting multiple events is impossible. However, because KVM copies int_state verbatim from vmcb02 to vmcb12, the spurious STI shadow is visible to L1 when running a nested VM, which can trip sanity checks, e.g. in VMware's VMM. Hoist the STI+CLI all the way to C code, as the aforementioned calls to guest_state_{enter,exit}_irqoff() already inform lockdep that IRQs are enabled/disabled, and taking a fault on VMRUN with RFLAGS.IF=1 is already possible. I.e. if there's kernel code that is confused by running with RFLAGS.IF=1, then it's already a problem. In practice, since GIF=0 also blocks NMIs, the only change in exposure to non-KVM code (relative to surrounding VMRUN with STI+CLI) is exception handling code, and except for the kvm_rebooting=1 case, all exception in the core VM-Enter/VM-Exit path are fatal. Use the "raw" variants to enable/disable IRQs to avoid tracing in the "no instrumentation" code; the guest state helpers also take care of tracing IRQ state. Oppurtunstically document why KVM needs to do STI in the first place.

AMD CPUs have a quirk (some would say "bug"), where the STI shadow bleeds into the guest's intr_state field if a #VMEXIT occurs during injection of an event, i.e. if the VMRUN doesn't complete before the subsequent #VMEXIT. The spurious "interrupts masked" state is relatively benign, as it only occurs during event injection and is transient. Because KVM is already injecting an event, the guest can't be in HLT, and if KVM is querying IRQ blocking for injection, then KVM would need to force an immediate exit anyways since injecting multiple events is impossible.

Re: Patch "fs/pipe: Read pipe->{head,tail} atomically outside pipe->mutex" has been added to the 5.10-stable tree

by Linus Torvalds

Note that this was a real fix, but the fix only matters if commit aaec5a95d596 ("pipe_read: don't wake up the writer if the pipe is still full") is in the tree. Now, the bug was pre-existing, and *maybe* it could be hit without that commit aaec5a95d596, but nobody has ever reported it, so it's very very unlikely. Also, this fix then had some fall-out, and while I think you've queued all the fallout fixes too, I think it might be a good idea to wait for more reports from the development tree before considering these for stable. Put another way: this fix caused some pain. It might not be worth back-porting to stable at all, and if it is, it might be worth waiting to see that there's no other fallout.

[PATCH 5.15] sched: sch_cake: add bounds checks to host bulk flow fairness counts

by Hagar Hemdan

From: Toke Høiland-Jørgensen <toke(a)redhat.com> [ Upstream commit 737d4d91d35b5f7fa5bb442651472277318b0bfd ] Even though we fixed a logic error in the commit cited below, syzbot still managed to trigger an underflow of the per-host bulk flow counters, leading to an out of bounds memory access. To avoid any such logic errors causing out of bounds memory accesses, this commit factors out all accesses to the per-host bulk flow counters to a series of helpers that perform bounds-checking before any increments and decrements. This also has the benefit of improving readability by moving the conditional checks for the flow mode into these helpers, instead of having them spread out throughout the code (which was the cause of the original logic error). As part of this change, the flow quantum calculation is consolidated into a helper function, which means that the dithering applied to the ost load scaling is now applied both in the DRR rotation and when a sparse flow's quantum is first initiated. The only user-visible effect of this is that the maximum packet size that can be sent while a flow stays sparse will now vary with +/- one byte in some cases. This should not make a noticeable difference in practice, and thus it's not worth complicating the code to preserve the old behaviour.

[PATCH v4] sched/topology: Enable topology_span_sane check only for debug builds

by Naman Jain

From: Saurabh Sengar <ssengar(a)linux.microsoft.com> On a x86 system under test with 1780 CPUs, topology_span_sane() takes around 8 seconds cumulatively for all the iterations. It is an expensive operation which does the sanity of non-NUMA topology masks. CPU topology is not something which changes very frequently hence make this check optional for the systems where the topology is trusted and need faster bootup. Restrict this to sched_verbose kernel cmdline option so that this penalty can be avoided for the systems who want to avoid it.

From: David Hildenbrand <david(a)redhat.com> commit 091c1dd2d4df6edd1beebe0e5863d4034ade9572 upstream. We currently assume that there is at least one VMA in a MM, which isn't true. So we might end up having find_vma() return NULL, to then de-reference NULL. So properly handle find_vma() returning NULL. This fixes the report: Oops: general protection fault, probably for non-canonical address 0xdffffc0000000000: 0000 [#1] PREEMPT SMP KASAN PTI KASAN: null-ptr-deref in range [0x0000000000000000-0x0000000000000007] CPU: 1 UID: 0 PID: 6021 Comm: syz-executor284 Not tainted 6.12.0-rc7-syzkaller-00187-gf868cd251776 #0 Hardware name: Google Google Compute Engine/Google Compute Engine, BIOS Google 10/30/2024 RIP: 0010:migrate_to_node mm/mempolicy.c:1090 [inline] RIP: 0010:do_migrate_pages+0x403/0x6f0 mm/mempolicy.c:1194 Code: ...

[PATCH 6.12/6.13] loongarch: Use ASM_REACHABLE

by Huacai Chen

From: Peter Zijlstra <peterz(a)infradead.org> commit 624bde3465f660e54a7cd4c1efc3e536349fead5 upstream. annotate_reachable() is unreliable since the compiler is free to place random code inbetween two consecutive asm() statements. This removes the last and only annotate_reachable() user. Backport to solve a build error since relevant commits have already been backported.

[PATCH linux-6.12.y] selftests/bpf: Clean up open-coded gettid syscall invocations

From: Kumar Kartikeya Dwivedi <memxor(a)gmail.com> Availability of the gettid definition across glibc versions supported by BPF selftests is not certain.

[PATCH 1/2] virt: sev-guest: Allocate request data dynamically

by Alexey Kardashevskiy

From: Nikunj A Dadhania <nikunj(a)amd.com> Commit ae596615d93d ("virt: sev-guest: Reduce the scope of SNP command mutex") narrowed the command mutex scope to snp_send_guest_request. However, GET_REPORT, GET_DERIVED_KEY, and GET_EXT_REPORT share the req structure in snp_guest_dev. Without the mutex protection, concurrent requests can overwrite each other's data. Fix it by dynamically allocating the request structure.

[PATCH 5.10] crypto: hisilicon/qm - inject error before stopping queue

by Xiangyu Chen

From: Weili Qian <qianweili(a)huawei.com> commit b04f06fc0243600665b3b50253869533b7938468 upstream. The master ooo cannot be completely closed when the accelerator core reports memory error. Therefore, the driver needs to inject the qm error to close the master ooo. Currently, the qm error is injected after stopping queue, memory may be released immediately after stopping queue, causing the device to access the released memory. Therefore, error is injected to close master ooo before stopping queue to ensure that the device does not access the released memory.

[PATCH v2 6.6] mm/mempolicy: fix unbalanced unlock in backported VMA check

by Alexey Panov

No upstream commit exists for this commit. The issue was introduced with backporting upstream commit 091c1dd2d4df ("mm/mempolicy: fix migrate_to_node() assuming there is at least one VMA in a MM"). The backport incorrectly added unlock logic to a path where mmap_lock was provided by external context in do_migrate_pages(), creating lock imbalance when no VMAs are found. This fixes the report: WARNING: bad unlock balance detected! 6.6.79 #1 Not tainted ------------------------------------- repro/9655 is trying to release lock (&mm->mmap_lock) at: [<ffffffff81daa36f>] mmap_read_unlock include/linux/mmap_lock.h:173 [inline] [<ffffffff81daa36f>] do_migrate_pages+0x59f/0x700 mm/mempolicy.c:1196 but there are no more locks to release! other info that might help us debug this: no locks held by repro/9655. stack backtrace: CPU: 1 PID: 9655 Comm: a Not tainted 6.6.79 #1 Hardware name: QEMU Standard PC (i440FX + PIIX, 1996), BIOS 1.16.2-debian-1.16.2-1 04/01/2014 Call Trace: <TASK> __dump_stack lib/dump_stack.c:88 [inline] dump_stack_lvl+0xd5/0x1b0 lib/dump_stack.c:106 __lock_release kernel/locking/lockdep.c:5431 [inline] lock_release+0x4b1/0x680 kernel/locking/lockdep.c:5774 up_read+0x12/0x20 kernel/locking/rwsem.c:1615 mmap_read_unlock include/linux/mmap_lock.h:173 [inline] do_migrate_pages+0x59f/0x700 mm/mempolicy.c:1196 kernel_migrate_pages+0x59b/0x780 mm/mempolicy.c:1665 __do_sys_migrate_pages mm/mempolicy.c:1684 [inline] __se_sys_migrate_pages mm/mempolicy.c:1680 [inline] __x64_sys_migrate_pages+0x92/0xf0 mm/mempolicy.c:1680 do_syscall_x64 arch/x86/entry/common.c:51 [inline] do_syscall_64+0x34/0xb0 arch/x86/entry/common.c:81 entry_SYSCALL_64_after_hwframe+0x68/0xd2 Found by Linux Verification Center (linuxtesting.org) with Syzkaller.

[PATCH] ASoC: amd: yc: Support mic on another Lenovo ThinkPad E16 Gen 2 model

by Thomas Mizrahi

The internal microphone on the Lenovo ThinkPad E16 model requires a quirk entry to work properly. This was fixed in a previous patch (linked below), but depending on the specific variant of the model, the product name may be "21M5" or "21M6". The following patch fixed this issue for the 21M5 variant: https://lore.kernel.org/all/20240725065442.9293-1-tiwai@suse.de/ This patch adds support for the microphone on the 21M6 variant. Link: https://github.com/ramaureirac/thinkpad-e14-linux/issues/31 Cc: <stable(a)vger.kernel.org> Signed-off-by: Thomas Mizrahi <thomasmizra(a)gmail.com> --- I recently acquired a ThinkPad E16 Gen 2 AMD and could not get the internal microphone working. After some research, I discovered this issue. Since my machine is a 21M6 variant, the required quirk was not applied by the existing patch. After applying this patch and testing on my machine, the microphone was immediately recognized and worked without further issues. sound/soc/amd/yc/acp6x-mach.c | 7 +++++++ 1 file changed, 7 insertions(+) diff --git a/sound/soc/amd/yc/acp6x-mach.c b/sound/soc/amd/yc/acp6x-mach.c index b16587d8f97a..a7637056972a 100644 --- a/sound/soc/amd/yc/acp6x-mach.c +++ b/sound/soc/amd/yc/acp6x-mach.c @@ -248,6 +248,13 @@ static const struct dmi_system_id yc_acp_quirk_table[] = { DMI_MATCH(DMI_PRODUCT_NAME, "21M5"), } }, + { + .driver_data = &acp6x_card, + .matches = { + DMI_MATCH(DMI_BOARD_VENDOR, "LENOVO"), + DMI_MATCH(DMI_PRODUCT_NAME, "21M6"), + } + }, { .driver_data = &acp6x_card, .matches = { -- 2.48.1

[PATCH v3] usb: hub: lack of clearing xHC resources

by Pawel Laszczak

The xHC resources allocated for USB devices are not released in correct order after resuming in case when while suspend device was reconnected. This issue has been detected during the fallowing scenario: - connect hub HS to root port - connect LS/FS device to hub port - wait for enumeration to finish - force host to suspend - reconnect hub attached to root port - wake host For this scenario during enumeration of USB LS/FS device the Cadence xHC reports completion error code for xHC commands because the xHC resources used for devices has not been properly released. XHCI specification doesn't mention that device can be reset in any order so, we should not treat this issue as Cadence xHC controller bug. Similar as during disconnecting in this case the device resources should be cleared starting form the last usb device in tree toward the root hub. To fix this issue usbcore driver should call hcd->driver->reset_device for all USB devices connected to hub which was reconnected while suspending.

It also appears that if the prefetched TRBs belong to a different ring whose doorbell is later rung, they may be used without refreshing from system RAM and the endpoint will stay idle if their cycle bit is stale. Other users complain about IOMMU faults on x86 systems, unsurprisingly. Deal with it by using existing quirk which allocates a dummy page after each transfer ring segment. This was seen to resolve both problems. RPi came up with a more efficient solution, shortening each segment by four TRBs, but it complicated the driver and they ditched it for this quirk. Also rename the quirk and add VL805 device ID macro.

It also appears that if the prefetched TRBs belong to a different ring whose doorbell is later rung, they may be used without refreshing from system RAM and the endpoint will stay idle if their cycle bit is stale. Other users complain about IOMMU faults on x86 systems, unsurprisingly. Deal with it by using existing quirk which allocates a dummy page after each transfer ring segment.

In the CMA allocation process, if it is found that the CMA area is occupied by in-use hugetlb folios, these in-use hugetlb folios need to be migrated to another location. When there are no available hugetlb folios in the free hugetlb pool during the migration of in-use hugetlb folios, new folios are allocated from the buddy system. A temporary state is set on the newly allocated folio. Upon completion of the hugetlb folio migration, the temporary state is transferred from the new folios to the old folios. Normally, when the old folios with the temporary state are freed, it is directly released back to the buddy system. However, due to the deferred freeing of hugetlb pages, the PageBuddy() check fails, ultimately leading to the failure of cma_alloc().

This function ensures that the hugetlb folios are properly released back to the buddy system after their migration is completed.

In the CMA allocation process, if it is found that the CMA area is occupied by in-use hugetlb folios, these in-use hugetlb folios need to be migrated to another location. When there are no available hugetlb folios in the free hugetlb pool during the migration of in-use hugetlb folios, new folios are allocated from the buddy system. A temporary state is set on the newly allocated folio. Upon completion of the hugetlb folio migration, the temporary state is transferred from the new folios to the old folios. Normally, when the old folios with the temporary state are freed, it is directly released back to the buddy system. However, due to the deferred freeing of hugetlb pages, the PageBuddy() check fails, ultimately leading to the failure of cma_alloc(). Here is a simplified call trace illustrating the process: cma_alloc() ->__alloc_contig_migrate_range() // Migrate in-use hugetlb folios ->unmap_and_move_huge_page() ->folio_putback_hugetlb() // Free old folios ->test_pages_isolated() ->__test_page_isolated_in_pageblock() ->PageBuddy(page) // Check if the page is in buddy To resolve this issue, we have implemented a function named wait_for_freed_hugetlb_folios().

This is especially easy to reproduce when the tmpfs is mount with the 'huge=within_size' parameter. Thanks to Kairui's reproducer, the issue can be easily replicated. The root cause of the problem is that swap readahead may asynchronously swap in order 0 folios into the swap cache, while the shmem mapping can still store large swap entries. Then an order 0 folio is inserted into the shmem mapping without splitting the large swap entry, which overwrites the original large swap entry, leading to data corruption. When getting a folio from the swap cache, we should split the large swap entry stored in the shmem mapping if the orders do not match, to fix this issue.

Fix two bugs during folio migration if the folio is poisoned. This patch (of 3): Commit 6da6b1d4a7df ("mm/hwpoison: convert TTU_IGNORE_HWPOISON to TTU_HWPOISON") introduce TTU_HWPOISON to replace TTU_IGNORE_HWPOISON in order to stop send SIGBUS signal when accessing an error page after a memory error on a clean folio. However during page migration, anon folio must be set with TTU_HWPOISON during unmap_*(). For pagecache we need some policy just like the one in hwpoison_user_mappings to set this flag. So move this policy from hwpoison_user_mappings to unmap_poisoned_folio to handle this warning properly.

Fix two bugs during folio migration if the folio is poisoned. This patch (of 3): Commit 6da6b1d4a7df ("mm/hwpoison: convert TTU_IGNORE_HWPOISON to TTU_HWPOISON") introduce TTU_HWPOISON to replace TTU_IGNORE_HWPOISON in order to stop send SIGBUS signal when accessing an error page after a memory error on a clean folio. However during page migration, anon folio must be set with TTU_HWPOISON during unmap_*(). For pagecache we need some policy just like the one in hwpoison_user_mappings to set this flag. So move this policy from hwpoison_user_mappings to unmap_poisoned_folio to handle this warning properly.

[PATCH 3/3] usb: chipidea: ci_hdrc_imx: implement usb_phy_init() error handling

by Fedor Pchelkin

usb_phy_init() may return an error code if e.g. its implementation fails to prepare/enable some clocks. Detect this early. Trying to disable it later on driver removal would result in a WARNING splat. And properly rollback on probe error path by calling the counterpart usb_phy_shutdown().

This triggers an early boot crash when using syslinux-efi to boot a recent kernel built with CONFIG_X86_5LEVEL=y and CONFIG_EFI_STUB=n, as the 0xff padding that now fills the unused PE/COFF header is copied into boot_params by the bootloader, and interpreted as the top half of the command line pointer. Fix this by sanitizing the boot_params before use. Note that there is no harm in calling this more than once; subsequent invocations are able to spot that the boot_params have already been cleaned up.

This triggers an early boot crash when using syslinux-efi to boot a recent kernel built with CONFIG_X86_5LEVEL=y and CONFIG_EFI_STUB=n, as the 0xff padding that now fills the unused PE/COFF header is copied into boot_params by the bootloader, and interpreted as the top half of the command line pointer. Fix this by sanitizing the boot_params before use. Note that there is no harm in calling this more than once; subsequent invocations are able to spot that the boot_params have already been cleaned up.

[PATCH v2 0/6] drm/v3d: Fix GPU reset issues on the Raspberry Pi 5

by Maíra Canal

This series addresses GPU reset issues reported in [1], where running a long compute job would trigger repeated GPU resets, leading to a UI freeze. Patches #1 and #2 prevent the same faulty job from being resubmitted in a loop, mitigating the first cause of the issue. However, the issue isn't entirely solved. Even with only a single GPU reset, the UI still freezes on the Raspberry Pi 5, indicating a GPU hang. Patches #3 to #5 address this by properly configuring the V3D_SMS registers, which are required for power management and resets in V3D 7.1. Patch #6 updates the DT maintainership, replacing Emma with the current v3d driver maintainer.

[REGRESSION] Long boot times due to USB enumeration

by Seïfane Idouchach

Dear all, I am reporting what I believe to be regression due to c0a40097f0bc81deafc15f9195d1fb54595cd6d0. After this change I am experiencing long boot times on a setup that has what seems like a bad usb. The progress of the boot gets halted while retrying (and ultimately failing) to enumerate the USB device and is only allowed to continue after giving up enumerating the USB device. On Arch Linux this manifests itself by a message from SystemD having a wait job on journald. Journald starts just after the enumeration fails with "unable to enumerate USB device". This results in longer boot times on average 1 minute longer than usual (usually around 10s). No stable kernel before this change exhibits the issue all stable kernels after this change exhibit the issue. See the related USB messages attached below (these messages are continuous and have not been snipped) : [...] [ 9.640854] usb 1-9: device descriptor read/64, error -110 [ 25.147505] usb 1-9: device descriptor read/64, error -110 [ 25.650779] usb 1-9: new high-speed USB device number 5 using xhci_hcd [ 30.907482] usb 1-9: device descriptor read/64, error -110 [ 46.480900] usb 1-9: device descriptor read/64, error -110 [ 46.589883] usb usb1-port9: attempt power cycle [ 46.990815] usb 1-9: new high-speed USB device number 6 using xhci_hcd [ 51.791571] usb 1-9: Device not responding to setup address.

[ 67.154086] usb 1-9: device not accepting address 7, error -71 [ 67.156426] usb usb1-port9: unable to enumerate USB device [...] This issue does not manifest in 44a45be57f85. I am available to test any patches to address this on my system since I understand this could be quite hard to replicate on any system. I am available to provide more information if I am able or with guidance to help troubleshoot the issue further. Wishing you all a good day. #regzbot introduced: c0a40097f0bc81deafc15f9195d1fb54595cd6d0

[PATCH] x86/microcode/AMD: Fix out-of-bounds on systems with CPU-less NUMA nodes

by Florent Revest

Currently, load_microcode_amd() iterates over all NUMA nodes, retrieves their CPU masks and unconditonally accesses per-CPU data for the first CPU of each mask. According to Documentation/admin-guide/mm/numaperf.rst: "Some memory may share the same node as a CPU, and others are provided as memory only nodes." Therefore, some node CPU masks may be empty and wouldn't have a "first CPU". On a machine with far memory (and therefore CPU-less NUMA nodes): - cpumask_of_node(nid) is 0 - cpumask_first(0) is CONFIG_NR_CPUS - cpu_data(CONFIG_NR_CPUS) accesses the cpu_info per-CPU array at an index that is 1 out of bounds This does not have any security implications since flashing microcode is a privileged operation but I believe this has reliability implications by potentially corrupting memory while flashing a microcode update. When booting with CONFIG_UBSAN_BOUNDS=y on an AMD machine that flashes a microcode update. I get the following splat: UBSAN: array-index-out-of-bounds in arch/x86/kernel/cpu/microcode/amd.c:X:Y index 512 is out of range for type 'unsigned long[512]' [...] Call Trace: dump_stack+0xdb/0x143 __ubsan_handle_out_of_bounds+0xf5/0x120 load_microcode_amd+0x58f/0x6b0 request_microcode_amd+0x17c/0x250 reload_store+0x174/0x2b0 kernfs_fop_write_iter+0x227/0x2d0 vfs_write+0x322/0x510 ksys_write+0xb5/0x160 do_syscall_64+0x6b/0xa0 entry_SYSCALL_64_after_hwframe+0x67/0xd1 This patch checks that a NUMA node has CPUs before attempting to update its first CPU's microcode.

Apply 0c5928deada1 for 6.12.y and 6.13.y

by Miguel Ojeda

Hi Greg, Sasha, Please consider applying the following commits for 6.12.y and 6.13.y: 0c5928deada1 ("rust: block: fix formatting in GenDisk doc") It is trivial, and should apply cleanly. This avoids a Clippy warning in the upcoming Rust 1.86.0 release (to be released in a few weeks). Thanks! Cheers, Miguel
