--- Comment #1 from ***@wizmail.org ---
Related, though possibly should be a separate bz:
API for a server application to arrange for Fast Open data to travel in
the SYN,ACK packet. I can see two possible implementations:
a) where the application pre-loads data before the SYN arrives
b) where the application supplies data between the SYN arriving and the
SYN,ACK being sent, permitting the data to depend on the initiating IP
Primary use-case is for SMTP, where the server banner is the first data sent
for the application-level protocol. I could see it being of use for TLS also,
where the Client Hello can travel on the SYN and the Server Hello on the
SYN,ACK (in fact, with kTLS this may not need a kernel/user API).
