2008-11-08fix macros up so they use the do { } while (/* CONSTCOND */ 0) idiomDavid Gwynne
ok deraadt@ otto@
2008-05-24Remove {tcp/udp}6_usrreq(); Since the normal ones nowThordur I. Bjornsson
take a proc argument, theres no need for these, since they are just wrappers. OK claudio@
2008-05-23Deal with the situation when TCP nfs mounts timeout and processesThordur I. Bjornsson
get hung in nfs_reconnect() because they do not have the proper privilages to bind to a socket, by adding a struct proc * argument to sobind() (and the *_usrreq() routines, and finally in{6}_pcbbind) and do the sobind() with proc0 in nfs_connect. OK markus@, blambert@. "go ahead" deraadt@. Fixes an issue reported by bernd@ (Tested by bernd@). Fixes PR5135 too.
2008-05-06remove tcp_drain code since it's not longer used; ok henning, feedback thibMarkus Friedl

relying on the mbuf chain layout; with claudio@ and krw@; ok henning@
2007-12-13implement sysctls to report IP, TCP, UDP, and ICMP statistics andReyk Floeter
change netstat to use them instead of accessing kvm for it. more protocols will be added later. discussed with deraadt@ claudio@ gilles@ ok deraadt@
2007-06-25merge tcp_set_iss() and tcp_set_tsm(); ok mcbride, djm (on earlier version)Markus Friedl
2007-06-15Drop the current random timestamps and the current ISN generationMarkus Friedl
code and replace both with a RFC1948 based method, so TCP clients now have monotonic ISN/timestamps. The server side uses completely random ISN/timestamps and does time-wait recycling (on port reuse). ok djm@, mcbride@; thanks to lots of testers

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@

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@
