If anyone has any objections, please let me know. ------------------ From: Tommi Rantala [ Upstream commit 41ab3e31bd50b42c85ac0aa0469642866aee2a9a ] ip6gre_tunnel_xmit() is leaking the skb when we hit this error branch, and the -1 return value from this function is bogus. Use the error handling we already have in place in ip6gre_tunnel_xmit() for this error case to fix this. Signed-off-by: Tommi Rantala Acked-by: Eric Dumazet Signed-off-by: David S.
