"value": "In the Linux kernel, the following vulnerability has been resolved:\n\nPCI: Avoid pci_dev_lock() AB/BA deadlock with sriov_numvfs_store()\n\nThe sysfs sriov_numvfs_store() path acquires the device lock before the\nconfig space access lock:\n\n sriov_numvfs_store\n device_lock # A (1) acquire device lock\n sriov_configure\n vfio_pci_sriov_configure # (for example)\n vfio_pci_core_sriov_configure\n pci_disable_sriov\n sriov_disable\n pci_cfg_access_lock\n pci_wait_cfg # B (4) wait for dev->block_cfg_access == 0\n\nPreviously, pci_dev_lock() acquired the config space access lock before the\ndevice lock:\n\n pci_dev_lock\n pci_cfg_access_lock\n dev->block_cfg_access = 1 # B (2) set dev->block_cfg_access = 1\n device_lock # A (3) wait for device lock\n\nAny path that uses pci_dev_lock(), e.g., pci_reset_function(), may\ndeadlock with sriov_numvfs_store() if the operations occur in the sequence\n(1) (2) (3) (4).\n\nAvoid the deadlock by reversing the order in pci_dev_lock() so it acquires\nthe device lock before the config space access lock, the same as the\nsriov_numvfs_store() path.\n\n[bhelgaas: combined and adapted commit log from Jay Zhou's independent\nsubsequent posting:\nhttps://lore.kernel.org/r/20220404062539.1710-1-jianjay.zhou@huawei.com]"
