From 0be43f82c4f4c4a999b53cf794513f7f1a4ed7f3 Mon Sep 17 00:00:00 2001 From: "Denis V. Lunev" Date: Mon, 24 Mar 2008 15:32:09 -0700 Subject: [NETNS]: Process netfilter hooks in initial namespace only. There were no packets in the namespace other than initial previously. This will be changed in the neareast future. Netfilters are not namespace aware and should be processed in the initial namespace only for now. Signed-off-by: Denis V. Lunev Signed-off-by: David S.
