--- Comment #41 from Mike Karels <kar...@freebsd.org> ---
Yes, if new data are received after the close, there is no way to deliver data
anywhere. If we ack it, the peer may just keep sending data, the window may go
closed, and the peer could probe it forever. The appropriate response is an
RST. And the connection can't do anything further, so CLOSED is the correct
state.
It seems to me that this situation is an unavoidable flaw of syn cookies.
