From f51d599fbecf4881a36466f0355da6b0b346ea70 Mon Sep 17 00:00:00 2001 From: Pavel Emelyanov Date: Mon, 14 Jan 2008 05:35:57 -0800 Subject: [PATCH] [NETNS][RAW]: Make /proc/net/raw(6) show per-namespace socket list. Pull the struct net pointer up to the showing functions to filter the sockets depending on their namespaces. Signed-off-by: Pavel Emelyanov Signed-off-by: David S.
