[PATCH 3.14 222/238] ipvs: avoid netns exit crash on ip_vs_conn_drop_conntrack

From: Greg Kroah-Hartman
Date: Fri Oct 03 2014 - 18:23:15 EST


3.14-stable review patch. If anyone has any objections, please let me know.

------------------

From: Julian Anastasov <ja@xxxxxx>

commit 2627b7e15c5064ddd5e578e4efd948d48d531a3f upstream.

commit 8f4e0a18682d91 ("IPVS netns exit causes crash in conntrack")
added second ip_vs_conn_drop_conntrack call instead of just adding
the needed check. As result, the first call still can cause
crash on netns exit. Remove it.
