From 4110cc255ddec59c79fba4d71cdd948d0a382140 Mon Sep 17 00:00:00 2001 From: "Eric W. Biederman" Date: Mon, 6 Aug 2012 08:41:13 +0000 Subject: sctp: Make the association hashtable handle multiple network namespaces - Use struct net in the hash calculation - Use sock_net(association.base.sk) in the association lookups. - On receive calculate the network namespace from skb->dev. - Pass struct net from receive down to the functions that actually do the association lookup.
