UAC3 class segment descriptors need to be verified whether their sizes match with the declared lengths and whether they fit with the allocated buffer sizes, too. Otherwise malicious firmware may lead to the unexpected OOB accesses.

2025-08-14net: usb: asix_devices: add phy_mask for ax88772 mdio busXu Yang
Without setting phy_mask for ax88772 mdio bus, current driver may create at most 32 mdio phy devices with phy address range from 0x00 ~ 0x1f. DLink DUB-E100 H/W Ver B1 is such a device. However, only one main phy device will bind to net phy driver. This is creating issue during system suspend/resume since phy_polling_mode() in phy_state_machine() will directly deference member of phydev->drv for non-main phy devices. Then NULL pointer dereference issue will occur. Due to only external phy or internal phy is necessary, add phy_mask for ax88772 mdio bus to workarnoud the issue.

2025-08-13net: kcm: Fix race condition in kcm_unattach()Sven Stegemann
syzbot found a race condition when kcm_unattach(psock) and kcm_release(kcm) are executed at the same time. kcm_unattach() is missing a check of the flag kcm->tx_stopped before calling queue_work(). If the kcm has a reserved psock, kcm_unattach() might get executed between cancel_work_sync() and unreserve_psock() in kcm_release(), requeuing kcm->tx_work right before kcm gets freed in kcm_done(). Remove kcm->tx_stopped and replace it by the less error-prone disable_work_sync().

2025-08-13net/sched: ets: use old 'nbands' while purging unused classesDavide Caratti
Shuang reported sch_ets test-case [1] crashing in ets_class_qlen_notify() after recent changes from Lion [2]. The problem is: in ets_qdisc_change() we purge unused DWRR queues; the value of 'q->nbands' is the new one, and the cleanup should be done with the old one. The problem is here since my first attempts to fix ets_qdisc_change(), but it surfaced again after the recent qdisc len accounting fixes. Fix it purging idle DWRR queues before assigning a new value of 'q->nbands', so that all purge operations find a consistent configuration: - old 'q->nbands' because it's needed by ets_class_find() - old 'q->nstrict' because it's needed by ets_class_is_strict() BUG: kernel NULL pointer dereference, address: 0000000000000000 #PF: supervisor read access in kernel mode #PF: error_code(0x0000) - not-present page PGD 0 P4D 0 Oops: Oops: 0000 [#1] SMP NOPTI CPU: 62 UID: 0 PID: 39457 Comm: tc Kdump: loaded Not tainted 6.12.0-116.el10.x86_64 #1 PREEMPT(voluntary) Hardware name: Dell Inc.

2025-08-13bnxt: fill data page pool with frags if PAGE_SIZE > BNXT_RX_PAGE_SIZEDavid Wei
The data page pool always fills the HW rx ring with pages. On arm64 with 64K pages, this will waste _at least_ 32K of memory per entry in the rx ring. Fix by fragmenting the pages if PAGE_SIZE > BNXT_RX_PAGE_SIZE. This makes the data page pool the same as the header pool. Tested with iperf3 with a small (64 entries) rx ring to encourage buffer circulation.

2025-08-13smb: client: remove redundant lstrp update in negotiate protocolWang Zhaolong
Commit 34331d7beed7 ("smb: client: fix first command failure during re-negotiation") addressed a race condition by updating lstrp before entering negotiate state. However, this approach may have some unintended side effects. The lstrp field is documented as "when we got last response from this server", and updating it before actually receiving a server response could potentially affect other mechanisms that rely on this timestamp. For example, the SMB echo detection logic also uses lstrp as a reference point. In scenarios with frequent user operations during reconnect states, the repeated calls to cifs_negotiate_protocol() might continuously update lstrp, which could interfere with the echo detection timing. Additionally, commit 266b5d02e14f ("smb: client: fix race condition in negotiate timeout by using more precise timing") introduced a dedicated neg_start field specifically for tracking negotiate start time. This provides a more precise solution for the original race condition while preserving the intended semantics of lstrp. Since the race condition is now properly handled by the neg_start mechanism, the lstrp update in cifs_negotiate_protocol() is no longer necessary and can be safely removed.

2025-08-13smb: client: fix mid_q_entry memleak leak with per-mid lockingWang Zhaolong
This is step 4/4 of a patch series to fix mid_q_entry memory leaks caused by race conditions in callback execution. In compound_send_recv(), when wait_for_response() is interrupted by signals, the code attempts to cancel pending requests by changing their callbacks to cifs_cancelled_callback. However, there's a race condition between signal interruption and network response processing that causes both mid_q_entry and server buffer leaks: ``` User foreground process cifsd cifs_readdir open_cached_dir cifs_send_recv compound_send_recv smb2_setup_request smb2_mid_entry_alloc smb2_get_mid_entry smb2_mid_entry_alloc mempool_alloc // alloc mid kref_init(&temp->refcount); // refcount = 1 mid[0]->callback = cifs_compound_callback; mid[1]->callback = cifs_compound_last_callback; smb_send_rqst rc = wait_for_response wait_event_state TASK_KILLABLE cifs_demultiplex_thread allocate_buffers server->bigbuf = cifs_buf_get() standard_receive3 ->find_mid() smb2_find_mid __smb2_find_mid kref_get(&mid->refcount) // +1 cifs_handle_standard handle_mid /* bigbuf will also leak */ mid->resp_buf = server->bigbuf server->bigbuf = NULL; dequeue_mid /* in for loop */ mids[0]->callback cifs_compound_callback /* Signal interrupts wait: rc = -ERESTARTSYS */ /* if (... || midQ[i]->mid_state == MID_RESPONSE_RECEIVED) *? midQ[0]->callback = cifs_cancelled_callback; cancelled_mid[i] = true; /* The change comes too late */ mid->mid_state = MID_RESPONSE_READY release_mid // -1 /* cancelled_mid[i] == true causes mid won't be released in compound_send_recv cleanup */ /* cifs_cancelled_callback won't executed to release mid */ ``` The root cause is that there's a race between callback assignment and execution. Fix this by introducing per-mid locking: - Add spinlock_t mid_lock to struct mid_q_entry - Add mid_execute_callback() for atomic callback execution - Use mid_lock in cancellation paths to ensure atomicity This ensures that either the original callback or the cancellation callback executes atomically, preventing reference count leaks when requests are interrupted by signals.

2025-08-13io_uring/io-wq: add check free worker before create new workerFengnan Chang
After commit 0b2b066f8a85 ("io_uring/io-wq: only create a new worker if it can make progress"), in our produce environment, we still observe that part of io_worker threads keeps creating and destroying. After analysis, it was confirmed that this was due to a more complex scenario involving a large number of fsync operations, which can be abstracted as frequent write + fsync operations on multiple files in a single uring instance. Since write is a hash operation while fsync is not, and fsync is likely to be suspended during execution, the action of checking the hash value in io_wqe_dec_running cannot handle such scenarios. Similarly, if hash-based work and non-hash-based work are sent at the same time, similar issues are likely to occur. Returning to the starting point of the issue, when a new work arrives, io_wq_enqueue may wake up free worker A, while io_wq_dec_running may create worker B. Ultimately, only one of A and B can obtain and process the task, leaving the other in an idle state. In the end, the issue is caused by inconsistent logic in the checks performed by io_wq_enqueue and io_wq_dec_running. Therefore, the problem can be resolved by checking for available workers in io_wq_dec_running.

2025-08-13block: restore default wbt enablementJulian Sun
The commit 245618f8e45f ("block: protect wbt_lat_usec using q->elevator_lock") protected wbt_enable_default() with q->elevator_lock; however, it also placed wbt_enable_default() before blk_queue_flag_set(QUEUE_FLAG_REGISTERED, q);, resulting in wbt failing to be enabled. Moreover, the protection of wbt_enable_default() by q->elevator_lock was removed in commit 78c271344b6f ("block: move wbt_enable_default() out of queue freezing from sched ->exit()"), so we can directly fix this issue by placing wbt_enable_default() after blk_queue_flag_set(QUEUE_FLAG_REGISTERED, q);. Additionally, this issue also causes the inability to read the wbt_lat_usec file, and the scenario is as follows: root@q:/sys/block/sda/queue# cat wbt_lat_usec cat: wbt_lat_usec: Invalid argument root@q:/data00/sjc/linux# ls /sys/kernel/debug/block/sda/rqos cannot access '/sys/kernel/debug/block/sda/rqos': No such file or directory root@q:/data00/sjc/linux# find /sys -name wbt /sys/kernel/debug/tracing/events/wbt After testing with this patch, wbt can be enabled normally.

2025-08-13locking: Fix __clear_task_blocked_on() warning from __ww_mutex_wound() pathJohn Stultz
The __clear_task_blocked_on() helper added a number of sanity checks ensuring we hold the mutex wait lock and that the task we are clearing blocked_on pointer (if set) matches the mutex. However, there is an edge case in the _ww_mutex_wound() logic where we need to clear the blocked_on pointer for the task that owns the mutex, not the task that is waiting on the mutex. For this case the sanity checks aren't valid, so handle this by allowing a NULL lock to skip the additional checks. K Prateek Nayak and Maarten Lankhorst also pointed out that in this case where we don't hold the owner's mutex wait_lock, we need to be a bit more careful using READ_ONCE/WRITE_ONCE in both the __clear_task_blocked_on() and __set_task_blocked_on() implementations to avoid accidentally tripping WARN_ONs if two instances race. So do that here as well. This issue was easier to miss, I realized, as the test-ww_mutex driver only exercises the wait-die class of ww_mutexes. I've sent a patch[1] to address this so the logic will be easier to test.

2025-08-12tls: handle data disappearing from under the TLS ULPJakub Kicinski
TLS expects that it owns the receive queue of the TCP socket. This cannot be guaranteed in case the reader of the TCP socket entered before the TLS ULP was installed, or uses some non-standard read API (eg. zerocopy ones). Replace the WARN_ON() and a buggy early exit (which leaves anchor pointing to a freed skb) with real error handling. Wipe the parsing state and tell the reader to retry. We already reload the anchor every time we (re)acquire the socket lock, so the only condition we need to avoid is an out of bounds read (not having enough bytes in the socket for previously parsed record len). If some data was read from under TLS but there's enough in the queue we'll reload and decrypt what is most likely not a valid TLS record. Leading to some undefined behavior from TLS perspective (corrupting a stream? missing an alert? missing an attack?) but no kernel crash should take place.

syzbot reported the following ABBA deadlock: CPU0 CPU1 ---- ---- n_vclocks_store() lock(&ptp->n_vclocks_mux) [1] (physical clock) pc_clock_adjtime() lock(&clk->rwsem) [2] (physical clock) ... ptp_clock_freerun() ptp_vclock_in_use() lock(&ptp->n_vclocks_mux) [3] (physical clock) ptp_clock_unregister() posix_clock_unregister() lock(&clk->rwsem) [4] (virtual clock) Since ptp virtual clock is registered only under ptp physical clock, both ptp_clock and posix_clock must be physical clocks for ptp_vclock_in_use() to lock &ptp->n_vclocks_mux and check ptp->n_vclocks. However, when unregistering vclocks in n_vclocks_store(), the locking ptp->n_vclocks_mux is a physical clock lock, but clk->rwsem of ptp_clock_unregister() called through device_for_each_child_reverse() is a virtual clock lock. Therefore, clk->rwsem used in CPU0 and clk->rwsem used in CPU1 are different locks, but in lockdep, a false positive occurs because the possibility of deadlock is determined through lock-class. To solve this, lock subclass annotation must be added to the posix_clock rwsem of the vclock.

2025-08-12ixgbe: prevent from unwanted interface name changesJedrzej Jagielski
Users of the ixgbe driver report that after adding devlink support by the commit a0285236ab93 ("ixgbe: add initial devlink support") their configs got broken due to unwanted changes of interface names. It's caused by automatic phys_port_name generation during devlink port initialization flow. To prevent from that set no_phys_port_name flag for ixgbe devlink ports.

2025-08-12devlink: let driver opt out of automatic phys_port_name generationJedrzej Jagielski
Currently when adding devlink port, phys_port_name is automatically generated within devlink port initialization flow. As a result adding devlink port support to driver may result in forced changes of interface names, which breaks already existing network configs. This is an expected behavior but in some scenarios it would not be preferable to provide such limitation for legacy driver not being able to keep 'pre-devlink' interface name. Add flag no_phys_port_name to devlink_port_attrs struct which indicates if devlink should not alter name of interface.

2025-08-12drm/amdgpu: fix task hang from failed job submission during process killLiu01 Tong
During process kill, drm_sched_entity_flush() will kill the vm entities. The following job submissions of this process will fail, and the resources of these jobs have not been released, nor have the fences been signalled, causing tasks to hang and timeout. Fix by check entity status in amdgpu_vm_ready() and avoid submit jobs to stopped entity. v2: add amdgpu_vm_ready() check before amdgpu_vm_clear_freed() in function amdgpu_cs_vm_handling().

2025-08-12ASoC: stm: stm32_i2s: Fix calc_clk_div() error handling in determine_rate()Sergio Perez Gonzalez
calc_clk_div() will only return a non-zero value (-EINVAL) in case of error. On the other hand, req->rate is an unsigned long. It seems quite odd that req->rate would be assigned a negative value, which is clearly not a rate, and success would be returned. Reinstate previous logic, which would just return error.

2025-08-12drm/amdgpu: Add PSP fw version check for fw reserve GFX commandFrank Min
The fw reserved GFX command is only supported starting from PSP fw version 0x3a0e14 and 0x3b0e0d. Older versions do not support this command. Add a version guard to ensure the command is only used when the running PSP fw meets the minimum version requirement. This ensures backward compatibility and safe operation across fw revisions.

2025-08-12io_uring/net: commit partial buffers on retryJens Axboe
Ring provided buffers are potentially only valid within the single execution context in which they were acquired. io_uring deals with this and invalidates them on retry. But on the networking side, if MSG_WAITALL is set, or if the socket is of the streaming type and too little was processed, then it will hang on to the buffer rather than recycle or commit it. This is problematic for two reasons: 1) If someone unregisters the provided buffer ring before a later retry, then the req->buf_list will no longer be valid. 2) If multiple sockers are using the same buffer group, then multiple receives can consume the same memory. This can cause data corruption in the application, as either receive could land in the same userspace buffer. Fix this by disallowing partial retries from pinning a provided buffer across multiple executions, if ring provided buffers are used.

2025-08-12rust: kbuild: clean output before running `rustdoc`Miguel Ojeda
`rustdoc` can get confused when generating documentation into a folder that contains generated files from other `rustdoc` versions. For instance, running something like: rustup default 1.78.0 make LLVM=1 rustdoc rustup default 1.88.0 make LLVM=1 rustdoc may generate errors like: error: couldn't generate documentation: invalid template: last line expected to start with a comment | = note: failed to create or modify "./Documentation/output/rust/rustdoc/src-files.js" Thus just always clean the output folder before generating the documentation -- we are anyway regenerating it every time the `rustdoc` target gets called, at least for the time being.
