3.13-stable review patch. If anyone has any objections, please let me know. ------------------ From: Xin Long <lucien.xin@xxxxxxxxx> [ Upstream commit 10ddceb22bab11dab10ba645c7df2e4a8e7a5db5 ] when ip_tunnel process multicast packets, it may check if the packet is looped back packet though 'rt_is_output_route(skb_rtable(skb))' in ip_tunnel_rcv(), but before that , skb->_skb_refdst has been dropped in iptunnel_pull_header(), so which leads to a panic. fix the bug: https://bugzilla.kernel.org/show_bug.cgi?id=70681 Signed-off-by: Xin Long <lucien.xin@xxxxxxxxx> Signed-off-by: David S.
