9 daysrandom: replace use of system_unbound_wq with system_dfl_wqMarco Crivellari1-4/+4
system_unbound_wq has been renamed to system_dfl_wq in 128ea9f6ccfb ("workqueue: Add system_percpu_wq and system_dfl_wq"), so update random.c's usage of it system_unbound_wq to reflect the new change. The old system_unbound_wq is slated for removal in the next few cycles. Suggested-by: Tejun Heo <tj@kernel.org> Signed-off-by: Marco Crivellari <marco.crivellari@suse.com> Signed-off-by: Jason A.

12 dayssmb: server: let smb_direct_cm_handler() call ib_drain_qp() after smb_direct_disconnect_rdma_work()Stefan Metzmacher1-3/+8
All handlers triggered by ib_drain_qp() should already see the broken connection. smb_direct_cm_handler() is called under a mutex of the rdma_cm, we should make sure ib_drain_qp() and all rdma layer logic completes and unlocks the mutex. It means free_transport() will also already see the connection as SMBDIRECT_SOCKET_DISCONNECTED, so we need to call crdma_[un]lock_handler(sc->rdma.cm_id) around ib_drain_qp(), rdma_destroy_qp(), ib_free_cq() and ib_dealloc_pd(). Otherwise we free resources while the ib_drain_qp() within smb_direct_cm_handler() is still running. We have to unlock before rdma_destroy_id() as it locks again.

12 dayssmb: server: call smb_direct_post_recv_credits() when the negotiation is doneStefan Metzmacher1-8/+28
We now activate sc->recv_io.posted.refill_work and sc->idle.immediate_work only after a successful negotiation, before sending the negotiation response. It means the queue_work(sc->workqueue, &sc->recv_io.posted.refill_work) in put_recvmsg() of the negotiate request, is a no-op now. It also means our explicit smb_direct_post_recv_credits() will have queue_work(sc->workqueue, &sc->idle.immediate_work) as no-op. This should make sure we don't have races and post any immediate data_transfer message that tries to grant credits to the peer, before we send the negotiation response, as that will grant the initial credits to the peer.

handle_response() dereferences the payload as a 4-byte handle without verifying that the declared payload size is at least 4 bytes. A malformed or truncated message from ksmbd.mountd can lead to a 4-byte read past the declared payload size. Validate the size before dereferencing.

2025-10-24slab: Fix obj_ext mistakenly considered NULL due to race conditionHao Ge1-5/+11
If two competing threads enter alloc_slab_obj_exts(), and the one that allocates the vector wins the cmpxchg(), the other thread that failed allocation mistakenly assumes that slab->obj_exts is still empty due to its own allocation failure. This will then trigger warnings with CONFIG_MEM_ALLOC_PROFILING_DEBUG checks in the subsequent free path. Therefore, let's check the result of cmpxchg() to see if marking the allocation as failed was successful. If it wasn't, check whether the winning side has succeeded its allocation (it might have been also marking it as failed) and if yes, return success.

2025-10-23io_uring: fix buffer auto-commit for multishot uring_cmdMing Lei1-11/+22
Commit 620a50c92700 ("io_uring: uring_cmd: add multishot support") added multishot uring_cmd support with explicit buffer upfront commit via io_uring_mshot_cmd_post_cqe(). However, the buffer selection path in io_ring_buffer_select() was auto-committing buffers for non-pollable files, which conflicts with uring_cmd's explicit upfront commit model. This way consumes the whole selected buffer immediately, and causes failure on the following buffer selection. Fix this by checking uring_cmd to identify operations that handle buffer commit explicitly, and skip auto-commit for these operations.

However, following commit 060913999d7a ("mm: migrate: support poisoned recover from migrate folio"), folio_mc_copy() is called before __folio_migrate_mapping(). If the latter fails (-EAGAIN), the copy will be done again to the same destination page. Since copy_highpage() already set the PG_mte_tagged flag, this second copy will warn.

2025-10-23slab: fix slab accounting imbalance due to defer_deactivate_slab()Vlastimil Babka1-3/+5
Since commit af92793e52c3 ("slab: Introduce kmalloc_nolock() and kfree_nolock().") there's a possibility in alloc_single_from_new_slab() that we discard the newly allocated slab if we can't spin and we fail to trylock. As a result we don't perform inc_slabs_node() later in the function. Instead we perform a deferred deactivate_slab() which can either put the unacounted slab on partial list, or discard it immediately while performing dec_slabs_node(). Either way will cause an accounting imbalance. Fix this by not marking the slab as frozen, and using free_slab() instead of deactivate_slab() for non-frozen slabs in free_deferred_objects(). For CONFIG_SLUB_TINY, that's the only possible case. By not using discard_slab() we avoid dec_slabs_node(). Fixes: af92793e52c3 ("slab: Introduce kmalloc_nolock() and kfree_nolock().")

Currently, during the LAN8814 PTP probe shared->phydev is only set if PTP clock gets actually set, otherwise the function will return before setting it. This is an issue as shared->phydev is unconditionally being used when IRQ is being handled, especially in lan8814_gpio_process_cap and since it was not set it will cause a NULL pointer exception and crash the kernel.

2025-10-23vsock: fix lock inversion in vsock_assign_transport()Stefano Garzarella1-19/+19
Syzbot reported a potential lock inversion deadlock between vsock_register_mutex and sk_lock-AF_VSOCK when vsock_linger() is called. The issue was introduced by commit 687aa0c5581b ("vsock: Fix transport_* TOCTOU") which added vsock_register_mutex locking in vsock_assign_transport() around the transport->release() call, that can call vsock_linger(). vsock_assign_transport() can be called with sk_lock held. vsock_linger() calls sk_wait_event() that temporarily releases and re-acquires sk_lock. During this window, if another thread hold vsock_register_mutex while trying to acquire sk_lock, a circular dependency is created. Fix this by releasing vsock_register_mutex before calling transport->release() and vsock_deassign_transport(). This is safe because we don't need to hold vsock_register_mutex while releasing the old transport, and we ensure the new transport won't disappear by obtaining a module reference first via try_module_get().

openvpn TCP encapsulation uses a custom queue to deliver packets to userspace.

Switch ovpn_tcp_poll to use datagram_poll_queue with the peer's user_queue, ensuring poll only signals readiness when userspace data is actually available.

Some protocols using TCP encapsulation (e.g., espintcp, openvpn) deliver userspace-bound packets through a custom skb queue rather than the standard sk_receive_queue. Introduce datagram_poll_queue that accepts an explicit receive queue, and convert datagram_poll into a wrapper around datagram_poll_queue.

Before this patch: - If should_notify_peers is true and the lock for send_peer_notif-- fails, peer event may be sent again in next mii_monitor loop, because should_notify_peers is still true. - If should_notify_peers is true and the lock for send_peer_notif-- succeeded, but the lock for peer event fails, the peer event will be lost.

The SMB3 calc_signature then jumps to the SMB2 variant if necessary.

2025-10-23gpiolib: acpi: Make set debounce errors non fatalHans de Goede1-12/+15
Commit 16c07342b542 ("gpiolib: acpi: Program debounce when finding GPIO") adds a gpio_set_debounce_timeout() call to acpi_find_gpio() and makes acpi_find_gpio() fail if this fails. But gpio_set_debounce_timeout() failing is a somewhat normal occurrence, since not all debounce values are supported on all GPIO/pinctrl chips. Making this an error for example break getting the card-detect GPIO for the micro-sd slot found on many Bay Trail tablets, breaking support for the micro-sd slot on these tablets. acpi_request_own_gpiod() already treats gpio_set_debounce_timeout() failures as non-fatal, just warning about them. Add a acpi_gpio_set_debounce_timeout() helper which wraps gpio_set_debounce_timeout() and warns on failures and replace both existing gpio_set_debounce_timeout() calls with the helper. Since the helper only warns on failures this fixes the card-detect issue.

2025-10-22net: hsr: prevent creation of HSR device with slaves from another netnsFernando Fernandez Mancera1-1/+7
HSR/PRP driver does not handle correctly having slaves/interlink devices in a different net namespace. Currently, it is possible to create a HSR link in a different net namespace than the slaves/interlink with the following command: ip link add hsr0 netns hsr-ns type hsr slave1 eth1 slave2 eth2 As there is no use-case on supporting this scenario, enforce that HSR device link matches netns defined by IFLA_LINK_NETNSID. The iproute2 command mentioned above will throw the following error: Error: hsr: HSR slaves/interlink must be on the same net namespace than HSR link.

2025-10-22sctp: avoid NULL dereference when chunk data buffer is missingAlexey Simakov1-6/+7
chunk->skb pointer is dereferenced in the if-block where it's supposed to be NULL only. chunk->skb can only be NULL if chunk->head_skb is not. Check for frag_list instead and do it just before replacing chunk->skb. We're sure that otherwise chunk->skb is non-NULL because of outer if() condition.

In ptp_ocp_sma_fb_init(), the code mistakenly used bp->sma[1] instead of bp->sma[i] inside a for-loop, which caused only SMA[1] to have its DIRECTION_CAN_CHANGE capability cleared. This led to inconsistent capability flags across SMA pins.

2025-10-22net: ravb: Ensure memory write completes before ringing TX doorbellLad Prabhakar1-0/+8
Add a final dma_wmb() barrier before triggering the transmit request (TCCR_TSRQ) to ensure all descriptor and buffer writes are visible to the DMA engine. According to the hardware manual, a read-back operation is required before writing to the doorbell register to guarantee completion of previous writes. Instead of performing a dummy read, a dma_wmb() is used to both enforce the same ordering semantics on the CPU side and also to ensure completion of writes.
