From cdb1876192dbe680b3ac955717fdf7f863c1762d Mon Sep 17 00:00:00 2001 From: Daniel Lezcano Date: Tue, 4 Mar 2008 13:45:33 -0800 Subject: [PATCH] [NETNS][IPV6] route6 - create route6 proc files for the namespace Make /proc/net/ipv6_route and /proc/net/rt6_stats to be per namespace. These proc files are now created when the network namespace is initialized. Signed-off-by: Daniel Lezcano Signed-off-by: Benjamin Thery Signed-off-by: David S.
