From 1c4f0197323254e463b642abf2c8361e2a924859 Mon Sep 17 00:00:00 2001 From: Daniel Lezcano Date: Wed, 14 Apr 2010 23:11:14 +0000 Subject: packet : remove init_net restriction The af_packet protocol is used by Perl to do ioctls as reported by Stephane Riviere: "Net::RawIP relies on SIOCGIFADDR et SIOCGIFHWADDR to get the IP and MAC addresses of the network interface." But in a new network namespace these ioctl fail because it is disabled for a namespace different from the init_net_ns. These two lines should not be there as af_inet and af_packet are namespace aware since a long time now. I suppose we forget to remove these lines because we sent the af_packet first, before af_inet was supported. Signed-off-by: Daniel Lezcano Reported-by: Stephane Riviere Signed-off-by: David S.
