Subject: TCP conntrack patch

Hello,

The attached patch is an implementation of TCP connection tracking
according to the article 'Real Stateful TCP Packet Filtering in
IP Filter' by Guido van Rooij [1]. It contains the new TCP connection
tracking with support to handle already established connections. Window
scaling support is added but it is untested.

The second patch contains the reworked conntrack testsuite with a new test
added.

The patch passed my simple, stupid, real-life tests, the modified
conntrack testsuite and the new test as well, but you are forewarned! :-)

Regards,
Jozsef
