Hannes Frederic Sowa a8c4a2522a ipv4: only create late gso-skb if skb is already set up with CHECKSUM_PARTIAL ... Otherwise we break the contract with GSO to only pass CHECKSUM_PARTIAL skbs down. This can easily happen with UDP+IPv4 sockets with the first MSG_MORE write smaller than the MTU, second write is a sendfile. Returning -EOPNOTSUPP lets the callers fall back into normal sendmsg path, were we calculate the checksum manually during copying. Commit d749c9cbff ("ipv4: no CHECKSUM_PARTIAL on MSG_MORE corked sockets") started to exposes this bug.
