BTRFS: error (device vdc: state EA) in cleanup_transaction:2055: errno=-2 No such entry This happens because create_pending_snapshot() initializes the new root item as a copy of the source root item. This includes the refs field, which is 0 for a deleted subvolume. The call to btrfs_insert_root() therefore inserts a root with refs == 0. btrfs_get_new_fs_root() then finds the root and returns -ENOENT if refs == 0, which causes create_pending_snapshot() to abort. Fix it by checking the source root's refs before attempting the snapshot, but after locking subvol_sem to avoid racing with deletion.

In the Linux kernel, the following vulnerability has been resolved: wifi: ath11k: rely on mac80211 debugfs handling for vif mac80211 started to delete debugfs entries in certain cases, causing a ath11k to crash when it tried to delete the entries later. Fix this by relying on mac80211 to delete the entries when appropriate and adding them from the vif_add_debugfs handler.

In the Linux kernel, the following vulnerability has been resolved: llc: make llc_ui_sendmsg() more robust against bonding changes syzbot was able to trick llc_ui_sendmsg(), allocating an skb with no headroom, but subsequently trying to push 14 bytes of Ethernet header [1] Like some others, llc_ui_sendmsg() releases the socket lock before calling sock_alloc_send_skb(). Then it acquires it again, but does not redo all the sanity checks that were performed. This fix: - Uses LL_RESERVED_SPACE() to reserve space. - Check all conditions again after socket lock is held again. - Do not account Ethernet header for mtu limitation.

That means it's impossible that svm_range_bo_release is running concurrently. However, there is no good way to annotate this. To avoid the problem, take a BO reference in svm_range_schedule_evict_svm_bo instead of in the worker. That way it's impossible for a BO to get freed while eviction work is pending and the cancel_work_sync call in svm_range_bo_release can be eliminated. v2: Use svm_bo_ref_unless_zero and explained why that's safe. Also removed redundant checks that are already done in amdkfd_fence_enable_signaling.

In the Linux kernel, the following vulnerability has been resolved: pds_core: Prevent race issues involving the adminq There are multiple paths that can result in using the pdsc's adminq. [1] pdsc_adminq_isr and the resulting work from queue_work(), i.e. pdsc_work_thread()->pdsc_process_adminq() [2] pdsc_adminq_post() When the device goes through reset via PCIe reset and/or a fw_down/fw_up cycle due to bad PCIe state or bad device state the adminq is destroyed and recreated. A NULL pointer dereference can happen if [1] or [2] happens after the adminq is already destroyed. In order to fix this, add some further state checks and implement reference counting for adminq uses. Reference counting was used because multiple threads can attempt to access the adminq at the same time via [1] or [2]. Additionally, multiple clients (i.e. pds-vfio-pci) can be using [2] at the same time. The adminq_refcnt is initialized to 1 when the adminq has been allocated and is ready to use. Users/clients of the adminq (i.e. [1] and [2]) will increment the refcnt when they are using the adminq. When the driver goes into a fw_down cycle it will set the PDSC_S_FW_DEAD bit and then wait for the adminq_refcnt to hit 1. Setting the PDSC_S_FW_DEAD before waiting will prevent any further adminq_refcnt increments. Waiting for the adminq_refcnt to hit 1 allows for any current users of the adminq to finish before the driver frees the adminq. Once the adminq_refcnt hits 1 the driver clears the refcnt to signify that the adminq is deleted and cannot be used. On the fw_up cycle the driver will once again initialize the adminq_refcnt to 1 allowing the adminq to be used again.

In the Linux kernel, the following vulnerability has been resolved: net: netdevsim: don't try to destroy PHC on VFs PHC gets initialized in nsim_init_netdevsim(), which is only called if (nsim_dev_port_is_pf()). Create a counterpart of nsim_init_netdevsim() and move the mock_phc_destroy() there. This fixes a crash trying to destroy netdevsim with VFs instantiated, as caught by running the devlink.sh test: BUG: kernel NULL pointer dereference, address: 00000000000000b8 RIP: 0010:mock_phc_destroy+0xd/0x30 Call Trace: <TASK> nsim_destroy+0x4a/0x70 [netdevsim] __nsim_dev_port_del+0x47/0x70 [netdevsim] nsim_dev_reload_destroy+0x105/0x120 [netdevsim] nsim_drv_remove+0x2f/0xb0 [netdevsim] device_release_driver_internal+0x1a1/0x210 bus_remove_device+0xd5/0x120 device_del+0x159/0x490 device_unregister+0x12/0x30 del_device_store+0x11a/0x1a0 [netdevsim] kernfs_fop_write_iter+0x130/0x1d0 vfs_write+0x30b/0x4b0 ksys_write+0x69/0xf0 do_syscall_64+0xcc/0x1e0 entry_SYSCALL_64_after_hwframe+0x6f/0x77
