[PATCH 083/145] ipvs: SCTP ports should be writable in ICMP packets

From: Kamal Mostafa
Date: Wed Jul 17 2013 - 19:17:18 EST


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

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

From: Julian Anastasov <ja@xxxxxx>

commit 06f3d7f973ec04290d86b7dd91b48d38d90433dc upstream.

Make sure that SCTP ports are writable when embedded in ICMP
from client, so that ip_vs_nat_icmp can translate them safely.
