--- Comment #1 from Michael Tuexen <tuexen@freebsd.org> ---
I guess you are referring to a race between
a) an incoming ACK segment being the third segment of the three way hand shake
b) an incoming non-SYN segment (for example the first data segment from the
peer
The non-SYN segment is responded with a RST, right?
If that is true, I discussed such a race with glebius@ recently...
