Detecting TCP regressions with tcpdiff
Determining if a TCP stack is working correctly is
hard. The tcpdiff project aims for a simpler goal:
To automatically detect differences in TCP behavior
between different versions of an operating system
and display those differences in an easy to understand
format. The value judgement of whether a certain
change between version X and Y of a TCP stack is
good or bad will be left to human eyes.

The initial version of tcpdiff presented at NYCBSDCon
2008 demonstrated that it could be used to detect
at least two major TCP bugs that were introduced
into FreeBSD in the past few years. The work from
that presentation can be viewed at
http://www.silby.com/nycbsdcon08/.
For BSDCan 2009, I hope to fix a number of bugs in
tcpdiff, make it easier to use, set up nightly tests
of FreeBSD, and improve it so that additional known
bugs can be detected. Additionally, I plan to run
it on OSes other than FreeBSD.
