My only concern is - If syn+data is sent by client and syn-ack only acks the ISN, then isnt this a sufficient indication that server now is not supporting the TFO? So for further connections to this server instead of sending syn+data, only ask for cookie. (fall back to the state where it was all started) (Note that this condition is different from syn+data is dropped in the nw.) Yuchung might be right in saying it doesn't lead to any performance penalty, however sending syn+data to a server seems a little odd when we know we have sufficient information to believe that it may not be accepted at first, retransmitted later. And otherwise we also have a way to fall back and re-attempt the TFO. If you guys still insist, I can stop here and continue on netdev. > Ketan has been busily adding support for TFO to a couple tools used in > cerowrt.
