------- Comment #1 from guy@xxxxxxxxxxxx  2007-08-01 18:33 GMT -------
To quote RFC 793:

    For sequence number purposes, the SYN is considered to occur before the
first actual data octet of the segment in which it occurs, while the FIN is
considered to occur after the last actual data octet in a segment in which it
occurs.

which, at least as I read it, indicates that a SYN or FIN segment can contain
data.

Given that, I'd say it's clearly a bug that DESEGMENT_UNTIL_FIN ignores data in
a FIN segment.
