From 7bddd0db6248d92adb1f547fd45507af4368d6fa Mon Sep 17 00:00:00 2001 From: Eric Dumazet Date: Sun, 4 Apr 2010 01:02:46 -0700 Subject: [PATCH] l2tp: unmanaged L2TPv3 tunnels fixes Followup to commit 789a4a2c (l2tp: Add support for static unmanaged L2TPv3 tunnels) One missing init in l2tp_tunnel_sock_create() could access random kernel memory, and a bit field should be unsigned.
