-Subject: [PATCH] wireguard: device: do not generate ICMP for non-IP packets
-
-commit 99fff5264e7ab06f45b0ad60243475be0a8d0559 upstream.
-
-If skb->protocol doesn't match the actual skb->data header, it's
-probably not a good idea to pass it off to icmp{,v6}_ndo_send, which is
-expecting to reply to a valid IP packet. So this commit has that early
-mismatch case jump to a later error label.
-
-Fixes: e7096c131e51 ("net: WireGuard secure network tunnel")
