Subject: [PATCH v2 net 0/4] af_unix: Fix two OOB issues.

From: Kuniyuki Iwashima <kuniyu@...gle.com>

Recently, two issues are reported regarding MSG_OOB.

Patch 1 fixes issues that happen when multiple consumed OOB
skbs are placed consecutively in the recv queue.

Patch 2 fixes an inconsistent behaviour that close()ing a socket
with a consumed OOB skb at the head of the recv queue triggers
-ECONNRESET on the peer's recv().


Changes:
  v2:
    * Patch 3: skip the leading consumed OOB skb instead of freeing it

  v1: https://lore.kernel.org/netdev/20250618043453.281247-1-kuni1840@gmail.com/


Kuniyuki Iwashima (4):
  af_unix: Don't leave consecutive consumed OOB skbs.
  af_unix: Add test for consecutive consumed OOB.
  af_unix: Don't set -ECONNRESET for consumed OOB skb.
  selftest: af_unix: Add tests for -ECONNRESET.
