https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D217637 --- Comment #27 from Michael Tuexen <tuexen@freebsd.org> --- (In reply to slw from comment #24) Consider a client doing a connect() call followed by a send() call. The con= nect call triggers the three way handshake. Assume that the third message is los= t. So the send call triggers the sending of a TCP segment with the same sequen= ce number as the third message of the handshake and it contains data. From the server perspective this TCP segment passes the syncookie checks. --=20 You are receiving this mail because: You are the assignee for the bug.=
