In the Linux kernel, the following vulnerability has been resolved:
af unix: Return immediately when manage oob() returns NULL for 0-length buffer.
Fahad Alharbi reported that recv(0, MSG PEEK) triggers busy-wait
in unix stream read generic() if recv() is blocking and the last
skb in the queue is MSG OOB skb.
In such a situation, TCP returns 0 immediately regardless of
blocking or non-blocking.
Let's follow the behaviour.
