3.12-stable review patch. If anyone has any objections, please let me know.
------------------
From: Chad Hanson <chanson@xxxxxxxxxxxxx>
commit 46d01d63221c3508421dd72ff9c879f61053cffc upstream.
Fix a broken networking check. Return an error if peer recv fails. If
secmark is active and the packet recv succeeds the peer recv error is
ignored.
