For AF_PACKET -injection, we need to support its call chain of: - - packet_sendmsg -> packet_snd -> packet_parse_headers -> - dev_parse_header_protocol -> parse_protocol - -Without a valid parse_protocol, this returns zero, and wireguard then -rejects the skb. So, this wires up the ip_tunnel handler for layer 3 -packets for that case. - -Reported-by: Hans Wippel <ndev@hwipl.net> -Signed-off-by: Jason A. Donenfeld <Jason@zx2c4.com> -Signed-off-by: David S.
