Modified files:
sys/netinet tcp_input.c
Log:
Remove the PAWS ack-on-ack debugging printf().
Note that the original RFC 1323 (PAWS) says in 4.2.1 that the out of
order / reverse-time-indexed packet should be acknowledged as specified
in RFC-793 page 69 then dropped. The original PAWS code in FreeBSD (1994)
simply acknowledged the segment unconditionally, which is incorrect, and
was fixed in 1.183 (2002). At the moment we do not do checks for SYN or FIN
in addition to (tlen != 0), which may or may not be correct, but the
worst that ought to happen should be a retry by the sender.
