(See earlier parts of thread here: 
http://netdev.vger.kernel.narkive.com/mwurLsMT/socket-receives-packet-to-multicast-
group-to-which-it-was-not-joined-since-kernel-3-13-10-1)

Was a bug report filed for this / was this fixed? 
I looked at the diffs from the referenced commit and the current version of 
udp_v4_early_demux and the changes appear to be 
minimal,
it doesn't look like ip_check_mc_rcu was added. Is that all that's needed?
