:Amongst all these `stream.c' emails, I noticed at least one which
:had a FreeBSD panic message saying there were no mbuf's free. I
:think it was for a 3.4 system. *That* is the bug which should be
:fixed.

I noticed that one too, but the author's email (if we are talking
about the same one) also said that the attack went on for an hour
before his machine paniced, which leads me to believe that the
TCP stack is not to blame. I've emailed the author some things
to try. Specifically, it is possible that the problem is related
to the machine's route table eating all available KVM from temporary
routes created by the spoofed source addresses. There are sysctl's
available to limit that sort of damage. It is also possible that we
still have a leak somewhere.
