[PATCH v1 net 0/3] af_unix: Minor fixes for MSG_OOB and MSG_PEEK.

Fahad Alharbi reported blocking recv(MSG_PEEK) could hog CPU
due to OOB skb.

Patch 1 and 2 fixes the issues and Patch 3 adds tests.


Kuniyuki Iwashima (3):
  af_unix: Update last skb marker in manage_oob().
  af_unix: Return immediately when manage_oob() returns NULL for
    0-length buffer.
  selftest: af_unix: Add zero-buffer test for msg_oob.c
