[comp.protocols.tcp-ip] TCP state diagram mistake

BRUCE@UMDD.BITNET (Bruce Crabill) (04/17/88)

This is probably a rediscovery of an old mistake, but in RFC-793 (TCP
Protocol Specification) in the TCP Connection State Diagram on page 23,
the transition from the SYN-SENT state to the SYN-RECEIVED state by the
reception of a bare SYN, indicates that this should case a bare ACK to
be sent.  However, on page 32 (Simultaneous Connection Synchronizaton)
and text on page 68, it would appear that the correct thing to do is to
send a SYN,ACK.  If this is a known problem, is there an RFC or other
location where known problems are kept?

Bruce,

    There is actually a move afoot to write a Host specification
document ala RFC 1009 (the Gateway specification).  One of the sections
in this document will be devoted to TCP.  I'm responsible for writing
the first draft of that section, and I plan to incorporate a list of
known problems in the TCP RFC.

    Anyone who has a list of errors they've found in the TCP specification
is encouraged to send those errors to me so they can be noted in the
RFC.
