2005-06-30implement PMTU checks fromMarkus Friedl
http://www.gont.com.ar/drafts/icmp-attacks-against-tcp.html i.e. don't act on ICMP-need-frag immediately if adhoc checks on the advertised mtu fail. the mtu update is delayed until a tcp retransmit happens. initial patch by Fernando Gont, tested by many.
2005-05-24Ignore ICMP Source Quench messages meant for TCP connections. (Details inFernando Gont

2005-04-05add tcp sack stats, similar to freebsd; ok deraadtMarkus Friedl
2005-03-09from freebsd:Markus Friedl
1. set rcv_laststart/rcv_lastend after checking the tcp window 2. pass rcv_laststart and rcv_lastend on the stack (shrink tcp state) ok henning, djm
2005-03-04- check th_ack against snd_una/max; from Raja Mukerji via hugh@Markus Friedl
- limit pool to tcp_sackhole_limit entries (sysctl-able) - stop sack option processing on pool_get errors - use SEQ_MIN/SEQ_MAX ok henning, hshoexer, deraadt
2005-02-271. tcp_xmit_timer(): remove extra rtt decrement (t_rtttime is 0-basedMarkus Friedl
while t_rtt was 1-based), update callers 2. define and use TCP_RTT_BASE_SHIFT instead of the hardcoded 2. 3. add missing shifts when t_srtt/t_rttvar are used. 4. update the comments: t_srtt uses 5 bits of fraction (not 3) and t_rttvar uses 4 bits 5. remove obsolete/unused macros TCP_RTT_SCALE and TCP_RTTVAR_SCALE 6. make sure rttmin is not > TCPTV_REXMTMAX parts from netbsd, ok mcbride, henning
2005-01-10Make sure bogus values don't make their way into tcp_xmit_timer() calculations.Ryan Thomas McBride
- Ignore ts_ecr if it is 0, or the resulting rtt is out of range. (use tp->t_rtttime instead) - Initialise tcp_now to 1, to avoid the 500ms window where a valid ts_ecr of 0 could be ignored. - Convert out-of-range rtt values to valid ones in tcp_xmit_timer(). ok frantzen@ markus@
2004-11-25fix for race between invocation for timer and network inputMarkus Friedl
1) add a reaper for TCP and SYN cache states (cf. netbsd pr 20390) 2) additional check for TCP_TIMER_ISARMED(TCPT_REXMT) in tcp_timer_persist() with mickey@; ok deraadt@

2002-05-16bring in ECN support from KAME.Kenjiro Cho
it consists of - ECN support in TCP - tunnel-egress and fragment reassembly rules in layer-3 not to lose congestion info at tunnel-egress and fragment reassembly to enable ECN in TCP, build a kernel with TCP_ECN, and then, turn it on by "sysctl -w net.inet.tcp.ecn=1". ok deraadt@

validate ICMPv6 too big messages (pmtud) based on pcb. we accept certain amount of non-validated ones, as IPv6 mandates ICMPv6 (so even for traffic from unconnected pcb, we need pmtud). sync with kame

2000-09-18Path MTU discovery based on NetBSD but with the decision to use the DFNiels Provos
flag delayed to ip_output(). That halves the code and reduces most of the route lookups. okay deraadt@
