You may have noticed that I've been doing a bit of hacking on the
SYN_cache_branch of the source tree recently. The reason for this is
that I want to get "compressed state for all embryonic connections" into
the main line for NetBSD 1.3.
I've done a fair bit of testing on i386, SPARC, and Alpha systems, and
fixed numerous bugs in the code. I _think_ I have worked out the last
of the semantic kinks...
Unfortunately, I can't test the code in all situations, only the in
normal regular usage these systems get... which is typically just
ssh connections (they do a lot of UDP traffic because they're either
NFS servers or the clients of those servers, but that doesn't test
out TCP connection creation :-).
What I really need is for this code to be tested in an environment
where there are MANY legitimate TCP connections being made... a WWW
server or busy mail server would be ideal. I would also like to know
how well it performs on these system when under attack from a SYN
flood. I can make my testing tools available.
Requirements for testing this code:
(a) You must be running NetBSD 1.2G. The diffs are relative to
that, and I can't really afford the time to back-port them
(b) You must be able to give me detailed information on how the
code fails, if it fails.
(c) You must be able to _really_ pound on it.
If you're unsure about (b) and (c), ask me for more details, and I can
fill you in...
That said, I'd love to get as many testers as possible... I don't want
to mainline this code if it's going to be buggy... If you can help me
out, I would really appreciate it...
