Further the appendix of RFC 791 gives the following example: Man, if it weren't for RAW sockets I would be now asking you "Now show me a legitimate IP packet that has one byte of data". Probably the correct test is therefore something like: if (ipprot_exists(iph->protocol) && pskb_may_pull(skb, ihl + 8)) goto out; And at that point this added overhead defeats the whole purpose of consolidating the pskb_may_pull() from the protocol inputs, into the generic IP input. :-( So I'm going to ask anyways, what cool RAW sockets app uses these 1 byte packets? :-) Franks a lot, David S.
