Hi all,
This patch provides i) support for Shared Use of Experimental TCP Options
(draft-ietf-tcpm-experimental-options-03) and ii) support for TCP Fast Open
(draft-ietf-tcpm-fastopen-02).
A new 'TFO=R' string is appended at the column info in case a client sends a
SYN packet with a Fast Open Cookie Request. Moreover, if the server responds
with a SYN-ACK containing a Fast Open Cookie option a 'TFO=C' is shown (as well
as in any subsequent client attempt to send SYN + DATA).
tcp.options.tfo display filter can be used in order to easily select the
complete TFO three-way handshake.
Chrome (and I think also Firefox) has support for client-side TFO. Linux 3.7
got both client and server-side support.
Fuzz-tested. Please check it in.
thanks a lot!
Ciao
FF
