That is exactly where I'd like to go :)
This will be part of a stateless engine, but some part of it are needed for a more complex (aka stateful) engine to help with connexion tracking for instance.

That is exactly what I am working on (TCP I mean, and the sample file is called tcp_handshake.c)

But, there is another very efficient tool to handle TCP stream reassembly and IP fragmentation, libnids :

What I intend to do here is to detect the proper SYN|ACK when a SYN has been sent (for instance), nothing more.
