From b76c4b27fee9c88294d3152784291fc6f6d23401 Mon Sep 17 00:00:00 2001 From: Pavel Emelyanov Date: Sun, 13 Apr 2008 22:29:59 -0700 Subject: [PATCH] [NETNS][DCCPV4]: Actually create ctl socket on each net and use it. Move the call to inet_ctl_sock_create to init callback (and inet_ctl_sock_destroy to exit one) and use proper ctl sock in dccp_v4_ctl_send_reset.
