"value": "In the Linux kernel, the following vulnerability has been resolved:\n\niavf: Fix hang during reboot/shutdown\n\nRecent commit 974578017fc1 (\"iavf: Add waiting so the port is\ninitialized in remove\") adds a wait-loop at the beginning of\niavf_remove() to ensure that port initialization is finished\nprior unregistering net device. This causes a regression\nin reboot/shutdown scenario because in this case callback\niavf_shutdown() is called and this callback detaches the device,\nmakes it down if it is running and sets its state to __IAVF_REMOVE.\nLater shutdown callback of associated PF driver (e.g. ice_shutdown)\nis called. That callback calls among other things sriov_disable()\nthat calls indirectly iavf_remove() (see stack trace below).\nAs the adapter state is already __IAVF_REMOVE then the mentioned\nloop is end-less and shutdown process hangs.\n\nThe patch fixes this by checking adapter's state at the beginning\nof iavf_remove() and skips the rest of the function if the adapter\nis already in remove state (shutdown is in progress).\n\nReproducer:\n1. Create VF on PF driven by ice or i40e driver\n2. Ensure that the VF is bound to iavf driver\n3. Reboot\n\n[52625.981294] sysrq: SysRq : Show Blocked State\n[52625.988377] task:reboot state:D stack: 0 pid:17359 ppid: 1 f2\n[52625.996732] Call Trace:\n[52625.999187] __schedule+0x2d1/0x830\n[52626.007400] schedule+0x35/0xa0\n[52626.010545] schedule_hrtimeout_range_clock+0x83/0x100\n[52626.020046] usleep_range+0x5b/0x80\n[52626.023540] iavf_remove+0x63/0x5b0 [iavf]\n[52626.027645] pci_device_remove+0x3b/0xc0\n[52626.031572] device_release_driver_internal+0x103/0x1f0\n[52626.036805] pci_stop_bus_device+0x72/0xa0\n[52626.040904] pci_stop_and_remove_bus_device+0xe/0x20\n[52626.045870] pci_iov_remove_virtfn+0xba/0x120\n[52626.050232] sriov_disable+0x2f/0xe0\n[52626.053813] ice_free_vfs+0x7c/0x340 [ice]\n[52626.057946] ice_remove+0x220/0x240 [ice]\n[52626.061967] ice_shutdown+0x16/0x50 [ice]\n[52626.065987] pci_device_shutdown+0x34/0x60\n[52626.070086] device_shutdown+0x165/0x1c5\n[52626.074011] kernel_restart+0xe/0x30\n[52626.077593] __do_sys_reboot+0x1d2/0x210\n[52626.093815] do_syscall_64+0x5b/0x1a0\n[52626.097483] entry_SYSCALL_64_after_hwframe+0x65/0xca"
