Instead, build bbr and rack as long aseither or both of INET and INET6 is enabled. There is no risk to anyonewho doesn't load one or both and then twiddle the relevant sysctls.Differential Revision: https://reviews.freebsd.org/D42088 List of files: /freebsd/sys/modules/tcp/Makefile Wed, 18 Oct 2023 16:13:12 +0200 Dag-Erling Smørgrav <des@FreeBSD.org> http://kernelsources.org:8080/source/history/freebsd/sys/modules/tcp/Makefile#031beb4e239bfce798af17f5fe8dba8bcaf13d99 sys: Remove $FreeBSD$: one-line sh patternRemove /^\s*#[#!]?\s*\$FreeBSD\$.*$\n/ List of files: /freebsd/sys/modules/tcp/Makefile Wed, 16 Aug 2023 19:54:58 +0200 Warner Losh <imp@FreeBSD.org> http://kernelsources.org:8080/source/history/freebsd/sys/modules/tcp/Makefile#093a8f8daf309b6cefc6a9f3ebd217938fcceb6a Revise r361712 to disable tcpmd5.ko for 'options TCP_SIGNATURE' List of files: /freebsd/sys/modules/tcp/Makefile Wed, 03 Jun 2020 20:42:28 +0200 John Baldwin <jhb@FreeBSD.org> http://kernelsources.org:8080/source/history/freebsd/sys/modules/tcp/Makefile#f45b1312960772485acf4b4c8f35a0cfb4f3dfbf modules: don't build ipsec/tcpmd5 if the kernel is configured for IPSECIPSEC_SUPPORT can currently only cope with either IPSEC || IPSEC_SUPPORT,not both. Refrain from building if IPSEC is set, as the resulting modulewon't be able to load anyways if it's built into the kernel.KERN_OPTS is safe here; for tied modules, it will reflect the kernelconfiguration. For untied modules, it will defer to whatever is set in^/sys/conf/config.mk, which doesn't set IPSEC for modules. The lattersituation has some risk to it for uncommon scenarios, but such is the lifeof untied kernel modules.Reported by: jenkins (a lot), O.

Thisis a completely separate TCP stack (tcp_bbr.ko) that will be built only ifyou add the make options WITH_EXTRA_TCP_STACKS=1 and also include the optionTCPHPTS. You can also include the RATELIMIT option if you have a NIC interface thatsupports hardware pacing, BBR understands how to use such a feature.Note that this commit also adds in a general purpose time-filter whichallows you to have a min-filter or max-filter. A filter allows you tohave a low (or high) value for some period of time and degrade slowlyto another value has time passes. You can find out the details ofBBR by looking at the original paper at:https://queue.acm.org/detail.cfm?id=3022184or consult many other web resources you can find on the webreferenced by "BBR congestion control". It should be noted thatBBRv1 (which this is) does tend to unfairness in cases of smallbuffered paths, and it will usually get less bandwidth in the caseof large BDP paths(when competing with new-reno or cubic flows). BBRis still an active research area and we do plan on implementing V2of BBR to see if it is an improvement over V1.Sponsored by: Netflix Inc.Differential Revision: https://reviews.freebsd.org/D21582 List of files: /freebsd/sys/modules/tcp/Makefile Tue, 24 Sep 2019 20:18:11 +0200 Randall Stewart <rrs@FreeBSD.org> http://kernelsources.org:8080/source/history/freebsd/sys/modules/tcp/Makefile#14b841d4a8e6c25d964f5e3bbda379a1541a27ec MFH @ r337607, in preparation for boarding List of files: /freebsd/sys/modules/tcp/Makefile Sat, 11 Aug 2018 06:26:29 +0200 Kyle Evans <kevans@FreeBSD.org> http://kernelsources.org:8080/source/history/freebsd/sys/modules/tcp/Makefile#399973c33d862e8860ecda55664179de0dd2e7bc Delete the example tcp stack "fastpath" whichwas only put in has an example.Sponsored by: Netflix inc.Differential Revision: https://reviews.freebsd.org/D16420 List of files: /freebsd/sys/modules/tcp/Makefile Tue, 24 Jul 2018 16:55:47 +0200 Randall Stewart <rrs@FreeBSD.org> http://kernelsources.org:8080/source/history/freebsd/sys/modules/tcp/Makefile#89e560f441bb214495715039288c99442b3b5aea This commit brings in a new refactored TCP stack called Rack.Rack includes the following features: - A different SACK processing scheme (the old sack structures are not used). - RACK (Recent acknowledgment) where counting dup-acks is no longer done instead time is used to knwo when to retransmit. (see the I-D) - TLP (Tail Loss Probe) where we will probe for tail-losses to attempt to try not to take a retransmit time-out. (see the I-D) - Burst mitigation using TCPHTPS - PRR (partial rate reduction) see the RFC.Once built into your kernel, you can select this stack by eithersocket option with the name of the stack is "rack" or by settingthe global sysctl so the default is rack.Note that any connection that does not support SACK will be kickedback to the "default" base FreeBSD stack (currently known as "default").To build this into your kernel you will need to enable in yourkernel: makeoptions WITH_EXTRA_TCP_STACKS=1 options TCPHPTSSponsored by: Netflix Inc.Differential Revision: https://reviews.freebsd.org/D15525 List of files: /freebsd/sys/modules/tcp/Makefile Thu, 07 Jun 2018 20:18:13 +0200 Randall Stewart <rrs@FreeBSD.org> http://kernelsources.org:8080/source/history/freebsd/sys/modules/tcp/Makefile#4222f9685c59013425ddbc1ee8c474536a56494e Tweak the Makefiles a bit to allow using "tcp" in MODULES_OVERRIDEto build the tcp modules.Sponsored by: Netflix, Inc.
