From aed069df099cd1a27900acb56bb892ec24c66ac4 Mon Sep 17 00:00:00 2001 From: Alexander Duyck Date: Thu, 14 Apr 2016 15:33:37 -0400 Subject: ip_tunnel_core: iptunnel_handle_offloads returns int and doesn't free skb This patch updates the IP tunnel core function iptunnel_handle_offloads so that we return an int and do not free the skb inside the function. This actually allows us to clean up several paths in several tunnels so that we can free the skb at one point in the path without having to have a secondary path if we are supporting tunnel offloads. In addition it should resolve some double-free issues I have found in the tunnels paths as I believe it is possible for us to end up triggering such an event in the case of fou or gue.
