2025-09-09igb: fix link test skipping when interface is admin downKohei Enju1-4/+1
The igb driver incorrectly skips the link test when the network interface is admin down (if_running == false), causing the test to always report PASS regardless of the actual physical link state. This behavior is inconsistent with other drivers (e.g. i40e, ice, ixgbe, etc.) which correctly test the physical link state regardless of admin state. Remove the if_running check to ensure link test always reflects the physical link state.

2025-09-09igb: Fix NULL pointer dereference in ethtool loopback testTianyu Xu1-2/+1
The igb driver currently causes a NULL pointer dereference when executing the ethtool loopback test. This occurs because there is no associated q_vector for the test ring when it is set up, as interrupts are typically not added to the test rings. Since commit 5ef44b3cb43b removed the napi_id assignment in __xdp_rxq_info_reg(), there is no longer a need to pass a napi_id to it. Therefore, simply use 0 as the last parameter.

2025-09-09amd/amdkfd: correct mem limit calculation for small APUsYifan Zhang1-12/+32
Current mem limit check leaks some GTT memory (reserved_for_pt reserved_for_ras + adev->vram_pin_size) for small APUs. Since carveout VRAM is tunable on APUs, there are three case regarding the carveout VRAM size relative to GTT: 1. 0 < carveout < gtt apu_prefer_gtt = true, is_app_apu = false 2. carveout > gtt / 2 apu_prefer_gtt = false, is_app_apu = false 3. 0 = carveout apu_prefer_gtt = true, is_app_apu = true It doesn't make sense to check below limitation in case 1 (default case, small carveout) because the values in the below expression are mixed with carveout and gtt. adev->kfd.vram_used[xcp_id] + vram_needed > vram_size - reserved_for_pt - reserved_for_ras - atomic64_read(&adev->vram_pin_size) gtt: kfd.vram_used, vram_needed, vram_size carveout: reserved_for_pt, reserved_for_ras, adev->vram_pin_size In case 1, vram allocation will go to gtt domain, skip vram check since ttm_mem_limit check already cover this allocation.

2025-09-09drm/amd/display: Drop dm_prepare_suspend() and dm_complete()Mario Limonciello (AMD)1-21/+0
[Why] dm_prepare_suspend() was added in commit 50e0bae34fa6b ("drm/amd/display: Add and use new dm_prepare_suspend() callback") to allow display to turn off earlier in the suspend sequence. This caused a regression that HDMI audio sometimes didn't work properly after resume unless audio was playing during suspend. [How] Drop dm_prepare_suspend() callback. All code in it will still run during dm_suspend(). Also drop unnecessary dm_complete() callback. dm_complete() was used for failed prepare and also for any case of successful resume. The code in it already runs in dm_resume(). This change will introduce more time that the display is turned on during suspend sequence. The compositor can turn it off sooner if desired.

2025-09-09hrtimers: Unconditionally update target CPU base after offline timer migrationXiongfeng Wang1-8/+3
When testing softirq based hrtimers on an ARM32 board, with high resolution mode and NOHZ inactive, softirq based hrtimers fail to expire after being moved away from an offline CPU: CPU0 CPU1 hrtimer_start(..., HRTIMER_MODE_SOFT); cpu_down(CPU1) ... hrtimers_cpu_dying() // Migrate timers to CPU0 smp_call_function_single(CPU0, returgger_next_event); retrigger_next_event() if (!highres && !nohz) return; As retrigger_next_event() is a NOOP when both high resolution timers and NOHZ are inactive CPU0's hrtimer_cpu_base::softirq_expires_next is not updated and the migrated softirq timers never expire unless there is a softirq based hrtimer queued on CPU0 later. Fix this by removing the hrtimer_hres_active() and tick_nohz_active() check in retrigger_next_event(), which enforces a full update of the CPU base. As this is not a fast path the extra cost does not matter.

2025-09-09tunnels: reset the GSO metadata before reusing the skbAntoine Tenart1-0/+6
If a GSO skb is sent through a Geneve tunnel and if Geneve options are added, the split GSO skb might not fit in the MTU anymore and an ICMP frag needed packet can be generated. In such case the ICMP packet might go through the segmentation logic (and dropped) later if it reaches a path were the GSO status is checked and segmentation is required. This is especially true when an OvS bridge is used with a Geneve tunnel attached to it. The following set of actions could lead to the ICMP packet being wrongfully segmented: 1. An skb is constructed by the TCP layer (e.g. gso_type SKB_GSO_TCPV4, segs >= 2). 2. The skb hits the OvS bridge where Geneve options are added by an OvS action before being sent through the tunnel. 3. When the skb is xmited in the tunnel, the split skb does not fit anymore in the MTU and iptunnel_pmtud_build_icmp is called to generate an ICMP fragmentation needed packet. This is done by reusing the original (GSO!) skb. The GSO metadata is not cleared. 4. The ICMP packet being sent back hits the OvS bridge again and because skb_is_gso returns true, it goes through queue_gso_packets... 5. ...where __skb_gso_segment is called. The skb is then dropped. 6. Note that in the above example on re-transmission the skb won't be a GSO one as it would be segmented (len > MSS) and the ICMP packet should go through. Fix this by resetting the GSO information before reusing an skb in iptunnel_pmtud_build_icmp and iptunnel_pmtud_build_icmpv6.

2025-09-09ceph: fix crash after fscrypt_encrypt_pagecache_blocks() errorMax Kellermann1-2/+4
The function move_dirty_folio_in_page_array() was created by commit ce80b76dd327 ("ceph: introduce ceph_process_folio_batch() method") by moving code from ceph_writepages_start() to this function. This new function is supposed to return an error code which is checked by the caller (now ceph_process_folio_batch()), and on error, the caller invokes redirty_page_for_writepage() and then breaks from the loop. However, the refactoring commit has gone wrong, and it by accident, it always returns 0 (= success) because it first NULLs the pointer and then returns PTR_ERR(NULL) which is always 0. This means errors are silently ignored, leaving NULL entries in the page array, which may later crash the kernel. The simple solution is to call PTR_ERR() before clearing the pointer.

2025-09-09ceph: always call ceph_shift_unused_folios_left()Max Kellermann1-2/+1
The function ceph_process_folio_batch() sets folio_batch entries to NULL, which is an illegal state. Before folio_batch_release() crashes due to this API violation, the function ceph_shift_unused_folios_left() is supposed to remove those NULLs from the array. However, since commit ce80b76dd327 ("ceph: introduce ceph_process_folio_batch() method"), this shifting doesn't happen anymore because the "for" loop got moved to ceph_process_folio_batch(), and now the `i` variable that remains in ceph_writepages_start() doesn't get incremented anymore, making the shifting effectively unreachable much of the time. Later, commit 1551ec61dc55 ("ceph: introduce ceph_submit_write() method") added more preconditions for doing the shift, replacing the `i` check (with something that is still just as broken): - if ceph_process_folio_batch() fails, shifting never happens - if ceph_move_dirty_page_in_page_array() was never called (because ceph_process_folio_batch() has returned early for some of various reasons), shifting never happens - if `processed_in_fbatch` is zero (because ceph_process_folio_batch() has returned early for some of the reasons mentioned above or because ceph_move_dirty_page_in_page_array() has failed), shifting never happens Since those two commits, any problem in ceph_process_folio_batch() could crash the kernel, e.g. this way: BUG: kernel NULL pointer dereference, address: 0000000000000034 #PF: supervisor write access in kernel mode #PF: error_code(0x0002) - not-present page PGD 0 P4D 0 Oops: Oops: 0002 [#1] SMP NOPTI CPU: 172 UID: 0 PID: 2342707 Comm: kworker/u778:8 Not tainted 6.15.10-cm4all1-es #714 NONE Hardware name: Dell Inc.

(Interestingly, the crash happens only if `huge_zero_folio` has already been allocated; without `huge_zero_folio`, is_huge_zero_folio(NULL) returns true and folios_put_refs() skips NULL entries instead of dereferencing them. That makes reproducing the bug somewhat unreliable. See https://lore.kernel.org/20250826231626.218675-1-max.kellermann@ionos.com for a discussion of this detail.)

2025-09-09ceph: fix race condition where r_parent becomes stale before sending messageAlex Markuze1-12/+69
When the parent directory's i_rwsem is not locked, req->r_parent may become stale due to concurrent operations (e.g. rename) between dentry lookup and message creation.

2025-09-09ceph: fix race condition validating r_parent before applying stateAlex Markuze6-107/+145
Add validation to ensure the cached parent directory inode matches the directory info in MDS replies. This prevents client-side race conditions where concurrent operations (e.g. rename) cause r_parent to become stale between request initiation and reply processing, which could lead to applying state changes to incorrect directory inodes. [ idryomov: folded a kerneldoc fixup and a follow-up fix from Alex to move CEPH_CAP_PIN reference when r_parent is updated: When the parent directory lock is not held, req->r_parent can become stale and is updated to point to the correct inode. However, the associated CEPH_CAP_PIN reference was not being adjusted. The CEPH_CAP_PIN is a reference on an inode that is tracked for accounting purposes. Moving this pin is important to keep the accounting balanced. When the pin was not moved from the old parent to the new one, it created two problems: The reference on the old, stale parent was never released, causing a reference leak. A reference for the new parent was never acquired, creating the risk of a reference underflow later in ceph_mdsc_release_request(). This patch corrects the logic by releasing the pin from the old parent and acquiring it for the new parent when r_parent is switched. This ensures reference accounting stays balanced. ] Cc: stable@vger.kernel.org Signed-off-by: Alex Markuze <amarkuze@redhat.com> Reviewed-by: Viacheslav Dubeyko <Slava.Dubeyko@ibm.com> Signed-off-by: Ilya Dryomov <idryomov@gmail.com>

The hotplug lock is indeed held during this time, as confirmed by the lockdep_assert_cpus_held() within mon_event_read() that calls mon_event_count() via IPI, but the lockdep tracking is not able to follow the IPI. Fresh CPU cache information via get_cpu_cacheinfo_level() from __mon_event_count() was added to support the fix for the issue where resctrl inappropriately maintained links to L3 cache information that will be stale in the case when the associated CPU goes offline. Keep the cacheinfo ID in struct rdt_mon_domain to ensure that resctrl does not maintain stale cache information while CPUs can go offline. Return to using a pointer to the L3 cache information (struct cacheinfo) in struct rmid_read, rmid_read::ci. Initialize rmid_read::ci before the IPI where it is used. CPU hotplug lock is held across rmid_read::ci initialization and use to ensure that it points to accurate cache information.

If mmu_notifier_register() fails, for example because a signal was pending, the mmu_notifier will not be registered. But when the VM gets destroyed, it will get unregistered anyway and that will cause one extra mmdrop(), which will eventually cause the mm of the process to be freed too early, and cause a use-after free. This bug happens rarely, and only when secure guests are involved. The solution is to check the return value of mmu_notifier_register() and return it to the caller (ultimately it will be propagated all the way to userspace).

2025-09-09mm/vmalloc, mm/kasan: respect gfp mask in kasan_populate_vmalloc()Uladzislau Rezki (Sony)3-14/+31
kasan_populate_vmalloc() and its helpers ignore the caller's gfp_mask and always allocate memory using the hardcoded GFP_KERNEL flag. This makes them inconsistent with vmalloc(), which was recently extended to support GFP_NOFS and GFP_NOIO allocations. Page table allocations performed during shadow population also ignore the external gfp_mask. To preserve the intended semantics of GFP_NOFS and GFP_NOIO, wrap the apply_to_page_range() calls into the appropriate memalloc scope. xfs calls vmalloc with GFP_NOFS, so this bug could lead to deadlock. There was a report here https://lkml.kernel.org/r/686ea951.050a0220.385921.0016.GAE@google.com This patch: - Extends kasan_populate_vmalloc() and helpers to take gfp_mask; - Passes gfp_mask down to alloc_pages_bulk() and __get_free_page(); - Enforces GFP_NOFS/NOIO semantics with memalloc_*_save()/restore() around apply_to_page_range(); - Updates vmalloc.c and percpu allocator call sites accordingly.

The user supplied buffer to hold the fiemap information page faults calling ocfs2_page_mkwrite() which will take a write lock (since v2.6.27-38-g00dc417fa3e7) of the same semaphore.

2025-09-09mm/mremap: fix regression in vrm->new_addr checkCarlos Llamas1-3/+6
Commit 3215eaceca87 ("mm/mremap: refactor initial parameter sanity checks") moved the sanity check for vrm->new_addr from mremap_to() to check_mremap_params(). However, this caused a regression as vrm->new_addr is now checked even when MREMAP_FIXED and MREMAP_DONTUNMAP flags are not specified. In this case, vrm->new_addr can be garbage and create unexpected failures. Fix this by moving the new_addr check after the vrm_implies_new_addr() guard. This ensures that the new_addr is only checked when the user has specified one explicitly.

2025-09-09percpu: fix race on alloc failed warning limitVlad Dumitrescu1-8/+12
The 'allocation failed, ...' warning messages can cause unlimited log spam, contrary to the implementation's intent. The warn_limit variable is accessed without synchronization. If more than <warn_limit> threads enter the warning path at the same time, the variable will get decremented past 0. Once it becomes negative, the non-zero check will always return true leading to unlimited log spam. Use atomic operation to access warn_limit and change condition to test for non-negative (>= 0) - atomic_dec_if_positive will return -1 once warn_limit becomes 0. Continue to print disable message alongside the last warning. While the change cited in Fixes is only adjacent, the warning limit implementation was correct before it. Only non-atomic allocations were considered for warnings, and those happened to hold pcpu_alloc_mutex while accessing warn_limit.

2025-09-09net: dsa: b53: fix ageing time for BCM53101Jonas Gorski1-4/+13
For some reason Broadcom decided that BCM53101 uses 0.5s increments for the ageing time register, but kept the field width the same [1]. Due to this, the actual ageing time was always half of what was configured. Fix this by adapting the limits and value calculation for BCM53101.

2025-09-09genetlink: fix genl_bind() invoking bind() after -EPERMAlok Tiwari1-0/+3
Per family bind/unbind callbacks were introduced to allow families to track multicast group consumer presence, e.g. to start or stop producing events depending on listeners. However, in genl_bind() the bind() callback was invoked even if capability checks failed and ret was set to -EPERM. This means that callbacks could run on behalf of unauthorized callers while the syscall still returned failure to user space. Fix this by only invoking bind() after "if (ret) break;" check i.e. after permission checks have succeeded.

2025-09-08PCI: mvebu: Fix use of for_each_of_range() iteratorKlaus Kudielka1-17/+4
5da3d94a23c6 ("PCI: mvebu: Use for_each_of_range() iterator for parsing "ranges"") simplified code by using the for_each_of_range() iterator, but it broke PCI enumeration on Turris Omnia (and probably other mvebu targets). Issue #1: To determine range.flags, of_pci_range_parser_one() uses bus->get_flags(), which resolves to of_bus_pci_get_flags(), which already returns an IORESOURCE bit field, and NOT the original flags from the "ranges" resource. Then mvebu_get_tgt_attr() attempts the very same conversion again. Remove the misinterpretation of range.flags in mvebu_get_tgt_attr(), to restore the intended behavior. Issue #2: The driver needs target and attributes, which are encoded in the raw address values of the "/soc/pcie/ranges" resource. According to of_pci_range_parser_one(), the raw values are stored in range.bus_addr and range.parent_bus_addr, respectively. range.cpu_addr is a translated version of range.parent_bus_addr, and not relevant here. Use the correct range structure member, to extract target and attributes. This restores the intended behavior.

The reason is that syzkaller injects a fault into the chunk allocation in trace_pid_list_alloc, causing a failure in trace_pid_list_set, which may trigger double register of the same tracepoint.

When buf_len is not 4-byte aligned in ath12k_wmi_mgmt_send(), the firmware asserts and triggers a recovery. The following error messages are observed: ath12k_pci 0004:01:00.0: failed to submit WMI_MGMT_TX_SEND_CMDID cmd ath12k_pci 0004:01:00.0: failed to send mgmt frame: -108 ath12k_pci 0004:01:00.0: failed to tx mgmt frame, vdev_id 0 :-108 ath12k_pci 0004:01:00.0: waiting recovery start... This issue was observed when running 'iw wlanx set power_save off/on' in MLO station mode, which triggers the sending of an SMPS action frame with a length of 27 bytes to the AP. To resolve the misalignment, use buf_len_aligned instead of buf_len when constructing the WMI TLV header.

git://git.kernel.org/pub/scm/linux/kernel/git/vfs/vfs Pull vfs fixes from Christian Brauner: "fuse: - Prevent opening of non-regular backing files. Fuse doesn't support non-regular files anyway. - Check whether copy_file_range() returns a larger size than requested. - Prevent overflow in copy_file_range() as fuse currently only supports 32-bit sized copies. - Cache the blocksize value if the server returned a new value as inode->i_blkbits isn't modified directly anymore. - Fix i_blkbits handling for iomap partial writes. By default i_blkbits is set to PAGE_SIZE which causes iomap to mark the whole folio as uptodate even on a partial write. But fuseblk filesystems support choosing a blocksize smaller than PAGE_SIZE risking data corruption. Simply enforce PAGE_SIZE as blocksize for fuseblk's internal inode for now. - Prevent out-of-bounds acces in fuse_dev_write() when the number of bytes to be retrieved is truncated to the fc->max_pages limit. virtiofs: - Fix page faults for DAX page addresses. Misc: - Tighten file handle decoding from userns. Check that the decoded dentry itself has a valid idmapping in the user namespace. - Fix mount-notify selftests. - Fix some indentation errors. - Add an FMODE_ flag to indicate IOCB_HAS_METADATA availability. This will be moved to an FOP_* flag with a bit more rework needed for that to happen not suitable for a fix. - Don't silently ignore metadata for sync read/write. - Don't pointlessly log warning when reading coredump sysctls" * tag 'vfs-6.17-rc6.fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/vfs/vfs: fuse: virtio_fs: fix page fault for DAX page address selftests/fs/mount-notify: Fix compilation failure. fhandle: use more consistent rules for decoding file handle from userns fuse: Block access to folio overlimit fuse: fix fuseblk i_blkbits for iomap partial writes fuse: reflect cached blocksize if blocksize was changed fuse: prevent overflow in copy_file_range return value fuse: check if copy_file_range() returns larger than requested size fuse: do not allow mapping a non-regular backing file coredump: don't pointlessly check and spew warnings fs: fix indentation style block: don't silently ignore metadata for sync read/write fs: add a FMODE_ flag to indicate IOCB_HAS_METADATA availability Please enter a commit message to explain why this merge is necessary, especially if it merges an updated upstream into a topic branch.
