{"id":"CVE-2022-50053","summary":"iavf: Fix reset error handling","details":"In the Linux kernel, the following vulnerability has been resolved:\n\niavf: Fix reset error handling\n\nDo not call iavf_close in iavf_reset_task error handling. Doing so can\nlead to double call of napi_disable, which can lead to deadlock there.\nRemoving VF would lead to iavf_remove task being stuck, because it\nrequires crit_lock, which is held by iavf_close.\nCall iavf_disable_vf if reset fail, so that driver will clean up\nremaining invalid resources.\nDuring rapid VF resets, HW can fail to setup VF mailbox. Wrong\nerror handling can lead to iavf_remove being stuck with:\n[ 5218.999087] iavf 0000:82:01.0: Failed to init adminq: -53\n...\n[ 5267.189211] INFO: task repro.sh:11219 blocked for more than 30 seconds.\n[ 5267.189520]       Tainted: G S          E     5.18.0-04958-ga54ce3703613-dirty #1\n[ 5267.189764] \"echo 0 \u003e /proc/sys/kernel/hung_task_timeout_secs\" disables this message.\n[ 5267.190062] task:repro.sh        state:D stack:    0 pid:11219 ppid:  8162 flags:0x00000000\n[ 5267.190347] Call Trace:\n[ 5267.190647]  \u003cTASK\u003e\n[ 5267.190927]  __schedule+0x460/0x9f0\n[ 5267.191264]  schedule+0x44/0xb0\n[ 5267.191563]  schedule_preempt_disabled+0x14/0x20\n[ 5267.191890]  __mutex_lock.isra.12+0x6e3/0xac0\n[ 5267.192237]  ? iavf_remove+0xf9/0x6c0 [iavf]\n[ 5267.192565]  iavf_remove+0x12a/0x6c0 [iavf]\n[ 5267.192911]  ? _raw_spin_unlock_irqrestore+0x1e/0x40\n[ 5267.193285]  pci_device_remove+0x36/0xb0\n[ 5267.193619]  device_release_driver_internal+0xc1/0x150\n[ 5267.193974]  pci_stop_bus_device+0x69/0x90\n[ 5267.194361]  pci_stop_and_remove_bus_device+0xe/0x20\n[ 5267.194735]  pci_iov_remove_virtfn+0xba/0x120\n[ 5267.195130]  sriov_disable+0x2f/0xe0\n[ 5267.195506]  ice_free_vfs+0x7d/0x2f0 [ice]\n[ 5267.196056]  ? pci_get_device+0x4f/0x70\n[ 5267.196496]  ice_sriov_configure+0x78/0x1a0 [ice]\n[ 5267.196995]  sriov_numvfs_store+0xfe/0x140\n[ 5267.197466]  kernfs_fop_write_iter+0x12e/0x1c0\n[ 5267.197918]  new_sync_write+0x10c/0x190\n[ 5267.198404]  vfs_write+0x24e/0x2d0\n[ 5267.198886]  ksys_write+0x5c/0xd0\n[ 5267.199367]  do_syscall_64+0x3a/0x80\n[ 5267.199827]  entry_SYSCALL_64_after_hwframe+0x46/0xb0\n[ 5267.200317] RIP: 0033:0x7f5b381205c8\n[ 5267.200814] RSP: 002b:00007fff8c7e8c78 EFLAGS: 00000246 ORIG_RAX: 0000000000000001\n[ 5267.201981] RAX: ffffffffffffffda RBX: 0000000000000002 RCX: 00007f5b381205c8\n[ 5267.202620] RDX: 0000000000000002 RSI: 00005569420ee900 RDI: 0000000000000001\n[ 5267.203426] RBP: 00005569420ee900 R08: 000000000000000a R09: 00007f5b38180820\n[ 5267.204327] R10: 000000000000000a R11: 0000000000000246 R12: 00007f5b383c06e0\n[ 5267.205193] R13: 0000000000000002 R14: 00007f5b383bb880 R15: 0000000000000002\n[ 5267.206041]  \u003c/TASK\u003e\n[ 5267.206970] Kernel panic - not syncing: hung_task: blocked tasks\n[ 5267.207809] CPU: 48 PID: 551 Comm: khungtaskd Kdump: loaded Tainted: G S          E     5.18.0-04958-ga54ce3703613-dirty #1\n[ 5267.208726] Hardware name: Dell Inc.
