https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D217637 --- Comment #21 from Sepherosa Ziehau <sepherosa@gmail.com> --- (In reply to Michael Tuexen from comment #18) Hmm, do any OS's TCP stacks really send data along w/ the last ACK in the 3= -way handshake at all? And if we are checking the syncookie, it indicates we suffered short-of-mem= ory previously. I don't think we need to record that situation. Let me rephrase my original suggestion (I am not a native speaker, sorry): Drop the last ACK w/ data, before syncookie is going to be checked. --=20 You are receiving this mail because: You are the assignee for the bug.=
