commit a6222602("ip_tunnel: fix kernel panic with icmp_dest_unreach") clear IPCB in ip_tunnel_xmit() , or else skb->cb[] may contain garbage from GSO segmentation layer. But commit 0e6fbc5b("ip_tunnels: extend iptunnel_xmit()") refactor codes, and it clear IPCB behind the dst_link_failure(). So clear IPCB in ip_tunnel_xmit() just like commti a6222602("ip_tunnel: fix kernel panic with icmp_dest_unreach"). Signed-off-by:
