From 457c4cbc5a3dde259d2a1f15d5f9785290397267 Mon Sep 17 00:00:00 2001 From: "Eric W. Biederman" Date: Wed, 12 Sep 2007 12:01:34 +0200 Subject: [NET]: Make /proc/net per network namespace This patch makes /proc/net per network namespace. It modifies the global variables proc_net and proc_net_stat to be per network namespace. The proc_net file helpers are modified to take a network namespace argument, and all of their callers are fixed to pass &init_net for that argument. This ensures that all of the /proc/net files are only visible and usable in the initial network namespace until the code behind them has been updated to be handle multiple network namespaces. Making /proc/net per namespace is necessary as at least some files in /proc/net depend upon the set of network devices which is per network namespace, and even more files in /proc/net have contents that are relevant to a single network namespace.
