From fbd02dd405d0724a0f25897ed4a6813297c9b96f Mon Sep 17 00:00:00 2001 From: Pravin B Shelar Date: Sun, 23 Mar 2014 22:06:36 -0700 Subject: ip_tunnel: Fix dst ref-count. Commit 10ddceb22ba (ip_tunnel:multicast process cause panic due to skb->_skb_refdst NULL pointer) removed dst-drop call from ip-tunnel-recv. Following commit reintroduce dst-drop and fix the original bug by checking loopback packet before releasing dst.
