In the Linux kernel, the following vulnerability has been resolved: fou: Dont allow 0 for FOU_ATTR_IPPROTO. fou_udp_recv() has the same problem mentioned in the previous patch. If FOU_ATTR_IPPROTO is set to 0, skb is not freed by fou_udp_recv() nor "resubmit"-ted in ip_protocol_deliver_rcu(). Lets forbid 0 for FOU_ATTR_IPPROTO.
