| * | implement sysctls to report IP, TCP, UDP, and ICMP statistics and |   reyk | 2007-12-13 | 1 | -2/+5 | |
| | | | | | | | | | change netstat to use them instead of accessing kvm for it. more protocols will be added later. discussed with deraadt@ claudio@ gilles@ ok deraadt@ | |||||
| * | merge tcp_set_iss() and tcp_set_tsm(); ok mcbride, djm (on earlier version) |   markus | 2007-06-25 | 1 | -3/+2 | |
| | | ||||||
| * | Drop the current random timestamps and the current ISN generation | markus | 2007-06-15 | 1 | -2/+4 | |
| | | | | | | | | 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 | |||||
| * | correct rfc; from Kris Katterjohn |   jmc | 2007-02-01 | 1 | -2/+2 | |

| * | implement PMTU checks from | markus | 2005-06-30 | 1 | -1/+11 | |
| | | | | | | | | 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. | |||||
| * | Ignore ICMP Source Quench messages meant for TCP connections. (Details in |   fgont | 2005-05-24 | 1 | -2/+1 | |

| | | ||||||
| * | from freebsd: | markus | 2005-03-09 | 1 | -4/+2 | |
| | | | | | | | 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 | |||||
| * | - check th_ack against snd_una/max; from Raja Mukerji via hugh@ | markus | 2005-03-04 | 1 | -3/+7 | |
| | | | | | | | | - 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 | |||||
| * | 1. tcp_xmit_timer(): remove extra rtt decrement (t_rtttime is 0-based | markus | 2005-02-27 | 1 | -10/+9 | |
| | | | | | | | | | | | | 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 | |||||
| * | Make sure bogus values don't make their way into tcp_xmit_timer() calculations. |   mcbride | 2005-01-10 | 1 | -1/+2 | |
| | | | | | | | | | | | - 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@ | |||||
| * | fix for race between invocation for timer and network input | markus | 2004-11-25 | 1 | -1/+6 | |
| | | | | | | | 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@ | |||||
