From e730c15519d09ea528b4d2f1103681fa5937c0e6 Mon Sep 17 00:00:00 2001 From: "Eric W. Biederman" Date: Mon, 17 Sep 2007 11:53:39 -0700 Subject: [NET]: Make packet reception network namespace safe This patch modifies every packet receive function registered with dev_add_pack() to drop packets if they are not from the initial network namespace. This should ensure that the various network stacks do not receive packets in a anything but the initial network namespace until the code has been converted and is ready for them.
