From 5c8cafd65e1448b1d55cad3fb1e42ad42607e5be Mon Sep 17 00:00:00 2001 From: "Denis V. Lunev" Date: Fri, 29 Feb 2008 11:19:22 -0800 Subject: [NETNS]: icmp(v6)_sk should not pin a namespace. So, change icmp(v6)_sk creation/disposal to the scheme used in the netlink for rtnl, i.e. create a socket in the context of the init_net and assign the namespace without getting a referrence later. Also use sk_release_kernel instead of sock_release to properly destroy such sockets. Signed-off-by: Denis V. Lunev Acked-by: Daniel Lezcano Signed-off-by: David S.
