Ahhh. Sounds like many of the bugs I've found in my own software. > I also agree with Mikael that this isn't an important issue, given that > syn-ack packets are quite tiny.

It's certainly not a security-threatening issue... but, as you said, it is a bug. > Phil: In the future, please try a bit harder to notify someone if you > believe that a bug is serious enough for posting to bugtraq. freebsd-net > is a relatively busy list, and things do get missed. Certainly. I appologize if I caused the FreeBSD developers any grief over my post. I'm not a FreeBSD user myself and wasn't aware of the http://www.freebsd.org/send-pr.html page until yesterday. I did submit a bug report there yesterday, which got assigned an ID of kern/39141, so when you commit the fix, you can update/close that case as well. Thanks again for your quick response.
