[PATCH -stable-3.9 13/15] ipvs: SCTP ports should be writable in ICMP packets

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Julian Anastasov <ja@xxxxxx>

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