Mainly, it's possible to get the iphdr and tcphdr from a sk_buff structure. As a consequence, a TCP probe called tcp.receive() was created and is probed every time a TCP packet is received, and a lot of useful fields is available, as the TCP flags. Also a small example that works like tcpdump for received TCP packets was created. This patch was tested on x86 and ppc machines, on 2.6.18 kernel and also on mainline one.
