https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=217637 Mike Karels <karels@freebsd.org> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |karels@freebsd.org --- Comment #41 from Mike Karels <karels@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. -- You are receiving this mail because: You are the assignee for the bug.help
