Kuniyuki IwashimaandGreg Kroah-Hartman c7498f9bc3 fou: Don't allow 0 for FOU_ATTR_IPPROTO. ...

[ Upstream commit 7a9bc9e3f4 ]

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().

Let's forbid 0 for FOU_ATTR_IPPROTO.

Fixes: 23461551c0 ("fou: Support for foo-over-udp RX path")
