ipv4: raw: Fix sending packets from raw sockets via IPsec tunnels
[ Upstream commit c9b3b81716c5b92132a6c1d4ac3c48a7b44082ab ] Since the referenced commit, the xfrm_inner_extract_output() function uses the protocol field to determine the address family. So not setting it for IPv4 raw sockets meant that such packets couldn't be tunneled via IPsec anymore. IPv6 raw sockets are not affected as they already set the protocol since 9c9c9ad ("ipv6: set skb->protocol on tcp, raw and ip6_append_data genereated skbs").
