https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D242492 --- Comment #1 from j2465@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 al= so, 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). --=20 You are receiving this mail because: You are on the CC list for the bug.=
