What it is

In the Linux kernel, the following vulnerability has been resolved:

af_unix: Fix a data-race in unix_dgram_peer_wake_me().

unix_dgram_poll() calls unix_dgram_peer_wake_me() without `other`'s

lock held and check if its receive queue is full. Here we need to

use unix_recvq_full_lockless() instead of unix_recvq_full(), otherwise

KCSAN will report a data-race.
