From 9dd776b6d7b0b85966b6ddd03e2b2aae59012ab1 Mon Sep 17 00:00:00 2001 From: Eric W. Biederman Date: Wed, 26 Sep 2007 22:04:26 -0700 Subject: [NET]: Add network namespace clone & unshare support. This patch allows you to create a new network namespace using sys_clone, or sys_unshare. As the network namespace is still experimental and under development clone and unshare support is only made available when CONFIG_NET_NS is selected at compile time. As this patch introduces network namespace support into code paths that exist when the CONFIG_NET is not selected there are a few additions made to net_namespace.h to allow a few more functions to be used when the networking stack is not compiled in.
