IPVS netns exit causes crash in conntrack
commit 8f4e0a18682d91abfad72ede3d3cb5f3ebdf54b4 upstream.
Quote from Patric Mc Hardy
"This looks like nfnetlink.c excited and destroyed the nfnl socket, but
ip_vs was still holding a reference to a conntrack. When the conntrack
got destroyed it created a ctnetlink event, causing an oops in
netlink_has_listeners when trying to use the destroyed nfnetlink
socket."
If nf_conntrack_netlink is loaded before ip_vs this is not a problem.
This patch simply avoids calling ip_vs_conn_drop_conntrack()
when netns is dying as suggested by Julian.
