In the Linux kernel, the following vulnerability has been resolved:
btrfs: fix match incorrectly in dev_args_match_device
syzkaller found a failed assertion:
assertion failed: (args->devid != (u64)-1) || args->missing, in fs/btrfs/volumes.c:6921
This can be triggered when we set devid to (u64)-1 by ioctl. In this
case, the match of devid will be skipped and the match of device may
succeed incorrectly.
Patch 562d7b1512f7 introduced this function which is used to match device.
This function contains two matching scenarios, we can distinguish them by
checking the value of args->missing rather than check whether args->devid
and args->uuid is default value.
