| * | 1. tcp_xmit_timer(): remove extra rtt decrement (t_rtttime is 0-based | markus | 2005-02-27 | 1 | -2/+2 | |
| | | | | | | | | | | | | 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 | |||||
| * | Modulate tcp_now by a random amount on a per-connection basis. |   mcbride | 2004-10-28 | 1 | -2/+2 | |
| | | | | | ok markus@ frantzen@ | |||||
| * | set the congestion window to two segments (instead of only one), this matches | markus | 2004-10-06 | 1 | -2/+2 | |
| | | | | | the window size he have when entering the established state. ok deraadt@ | |||||
| * | don't send partial segments if SS_ISSENDING is set, remember | markus | 2004-09-16 | 1 | -4/+12 | |

| * | work around an LP64 problem where we report an excessively large window | brad | 2004-05-31 | 1 | -3/+3 | |
| | | | | | | | | | due to incorrect mixing of types. From NetBSD ok cedric@ markus@ | |||||
| * | Replace RSA-derived md5 code with code derived from Colin Plumb's PD version. |   millert | 2004-05-07 | 1 | -2/+2 | |
| | | | | | | | This moves md5.c out of libkern and into sys/crypto where it belongs (as requested by markus@). Note that md5.c is still mandatory (dev/rnd.c uses it). Verified with IPsec + hmac-md5 and tcp md5sig. OK henning@ and hshoexer@ | |||||

| | | | | | | | | | interface MTU. - break a tcp_output() -> tcp_mtudisc() -> tcp_output() infinite recursion when the TCP mss ends up larger than the interface MTU (when the if_mtu is smaller than the tcp header). connections will still stall feedback from itojun@, claudio@ and provos and testing from beck@ | |||||

| | | | | | | | one tcp segment, improves performance of tcp over interfaces with large mtu (e.g. lo0); based on similar change in netbsd; ok djm, henning, henric, millert, deraadt | |||||
| * | Fix a problem where passing NULL as a pointer with varargs does not promote |   pefo | 2002-08-28 | 1 | -2/+2 | |
| | | | | | | | | | NULL to full 64 bits on a 64 bit address system. Soultion is to add a (void *) cast before NULL. This makes a 64 bit MIPS kernel work and will probably help future 64 bit ports as well. OK from art@ | |||||

| * | bring in ECN support from KAME. |   kjc | 2002-05-16 | 1 | -1/+62 | |
| | | | | | | | | | | | | | 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@ | |||||

| * | Always defer output TCP checksumming until ip_output() (or hardware, |   angelos | 2001-06-25 | 1 | -43/+8 | |
| | | | | | | if it exists). Cuts down on code a bit, and we don't need to look at the routing entry at TCP. Based on NetBSD. UDP case to follow. | |||||
| * | Use in_cksum_phdr() rather than in_cksum() -- from NetBSD | angelos | 2001-06-25 | 1 | -2/+8 | |
| | | ||||||
| * | Likewise, only use outgoing TCP/UDP hardware checksumming if the | angelos | 2001-06-23 | 1 | -2/+3 | |
| | | | | | interface is not in bridge mode. | |||||
| * | Keep stats on TCP/UDP hardware checksumming. | angelos | 2001-06-23 | 1 | -1/+2 | |

| * | TCP/UDP hardware checksumming. Untested, since txp dies when it tries | angelos | 2001-06-23 | 1 | -1/+18 | |
| | | | | | to compute the checksums. Still, it shouldn't affect anything. | |||||
| * | fix up mtu for routes and ongoing tcp connection when if mtu changes | provos | 2001-06-23 | 1 | -1/+11 | |

| * | Two fixes from Stevens via davidg@freebsd, bug report by | provos | 2001-05-31 | 1 | -5/+8 | |
| | | | | | | | | | | | armin@wolfermann.org - set the persist timer so that connections in CLOSING state timeout - honor keep-alive timer in CLOSING state. Fixes the problem in simulaneous close situation where connections would never leave the CLOSING state and stay arround indefinitly. | |||||
| * | on expiry of pmtu route, retry higher mtu. okay angelos@ | provos | 2000-09-25 | 1 | -3/+2 | |

| * | Path MTU discovery based on NetBSD but with the decision to use the DF | provos | 2000-09-18 | 1 | -2/+4 | |
| | | | | | | flag delayed to ip_output(). That halves the code and reduces most of the route lookups. okay deraadt@ | |||||

| * | TCP SACK fixes via Tom Henderson (tomh@cs.berkeley.edu): | provos | 2000-02-21 | 1 | -21/+32 | |
| | | | | | | | | | | | | | - tcp_sack_adjust() was completely rewritten, since it was erroneously referencing receiver side sequence numbers and comparing with sender side sequence numbers (thanks to Arun Desai (adesai@cisco.com) who discovered the problem) - in tcp_output(), moved assignment of sendalot=0 to the piece of code immediately following the search for sack-eligible retransmissions (bug identified by Arun Desai). - tcp_input() was not clearing t_dupacks if fewer than three dupacks arrived between acks of new data. (bug identified by Gaurav Banga (gaurav@netapp.com)) | |||||
