123fd2a9 - Add the BBR and RACK stacks to the LINT kernel.

Wed, 18 Oct 2023 14:13:12 +0000

Add the BBR and RACK stacks to the LINT kernel.While here, drop the EXTRA_TCP_STACKS option, which serves no purpose andshould never have been added. 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(cherry picked from commit 3a338c534154164504005beb00a3c6feb03756cc) List of files: /freebsd-14.2/sys/conf/options

4ef1c6f7 - base: Remove support for the VTOC8 partitioning scheme

Wed, 26 Jul 2023 11:08:37 +0000

base: Remove support for the VTOC8 partitioning schemeThe removal of the sparc64 support in February 2020 obsoleted theVTOC8 partitioning scheme as no other FreeBSD platform makes useof it. Moreover, the code is bitrotting as nothing defines e. g.LOADER_VTOC8_SUPPORT any more and, thus, should go now, too. Withthis change, the following commits are reverted as far as VTOC8is concerned and parts haven't already previously been deletedalong with prior sparc64 removals:094fcb157d4c98211899cf09d06e2cf19149b7e0a7d366e9589c95feda6f3bc78c59c6355d51f126ba8d50d08b9df4e8213f9a6997ff6792ecebcd9bThe alignment example d9711c28efc4ec89ba5ea11f8fd63e9d0a7fc81badded to the VTOC8 section of gpart.8 is folded into the MBR one.This should finally conclude the deorbit of sparc64-specific bits.

96eb0d90 - tcp: With the right options in the kernel cc_cubic stays in slowstart always.

Wed, 28 Jun 2023 15:18:47 +0000

tcp: With the right options in the kernel cc_cubic stays in slowstart always.So this is a subtle bug I have found in cubic. If you compile a number of options into the kernel (accounting and tracking) thenall of the kernel code "knows" the proper offset of t_rttupdatecnt however cubic does not see the options (and htcp too) and thuswill look for the count in the wrong place seeing 0. Which then means it never builds an MIN RTT which then means italways hangs in slowstart.The solution is to put all options that effect tcpcb size into the opt_global.h so that the kernelhas a consistent view of the tcpcb size.Reviewed by: tuexen, rscheffSponsored by: Netflix IncDifferential Revision:https://reviews.freebsd.org/D40761 List of files: /freebsd-14.2/sys/conf/options

2404380a - tslog: Optionally instrument pmap_zero_page

Mon, 29 May 2023 23:03:14 +0000

tslog: Optionally instrument pmap_zero_pageBooting an amd64 kernel on Firecracker with 1 CPU and 128 MB of RAM,pmap_zero_page is responsible for 4.6 ms of the 25.0 ms of boot time.This is not in fact time spent zeroing pages though; almost all ofthat time is spent in a first-touch penalty, presumably due to thehost Linux kernel faulting in backing pages one by one.There's probably a way to improve that by teaching Firecracker tofault in all the VM's pages from the start rather than having themfaulted in one at a time, but that's outside of FreeBSD's control.This commit adds a TSLOG_PAGEZERO option which enables TSLOG on theamd64 pmap_zero_page function; it's a separate option (turned offby default even if TSLOG is enabled) since zeroing pages happensenough that it can easily fill the TSLOG buffer and prevent othertiming information from being recorded.Sponsored by: https://www.patreon.com/cpercivaDifferential Revision: https://reviews.freebsd.org/D40326 List of files: /freebsd-14.2/sys/conf/options

73ee5756 - Fixes in the tcp infrastructure with respect to stack changes as well as other infrastructure updates for incoming rack features.

Sat, 01 Apr 2023 05:46:38 +0000

Fixes in the tcp infrastructure with respect to stack changes as well as other infrastructure updates for incoming rack features.So stack switching as always been a bit of a issue. We currently use a break before make setup which means thatif something goes wrong you have to try to get back to a stack. This patch among a lot of other things changes that sothat it is a make before break. We also expand some of the function blocks in prep for new features in rack that will allowmore controlled pacing. We also add other abilities such as the pathway for a stack to query a previous stack to acquire fromit critical state information so things in flight don't get dropped or mis-handled when switching stacks. We also add theconcept of a timer granularity. This allows an alternate stack to change from the old ticks granularity to microseconds andof course this even gives us a pathway to go to nanosecond timekeeping if we need to (something for the data center to considerfor sure).Once all this lands I will then update rack to begin using all these new features.Reviewed by: tuexenSponsored by: Netflix IncDifferential Revision: https://reviews.freebsd.org/D39210 List of files: /freebsd-14.2/sys/conf/options

19e43c16 - netlink: add netlink KPI to the kernel by default

Mon, 27 Mar 2023 11:59:30 +0000

netlink: add netlink KPI to the kernel by defaultThis change does the following:Base Netlink KPIs (ability to register the family, parse and/or write a Netlink message) are always present in the kernel. Specifically,* Implementation of genetlink family/group registration/removal, some base accessors (netlink_generic_kpi.c, 260 LoC) are compiled in unconditionally.* Basic TLV parser functions (netlink_message_parser.c, 507 LoC) are compiled in unconditionally.* Glue functions (netlink<>rtsock), malloc/core sysctl definitions (netlink_glue.c, 259 LoC) are compiled in unconditionally.* The rest of the KPI _functions_ are defined in the netlink_glue.c, but their implementation calls a pointer to either the stub function or the actual function, depending on whether the module is loaded or not.This approach allows to have only 1k LoC out of ~3.7k LoC (current sys/netlink implementation) in the kernel, which will not grow further.It also allows for the generic netlink kernel customers to load successfully without requiring Netlink module and operate correctly once Netlink module is loaded.Reviewed by: impMFC after: 2 weeksDifferential Revision: https://reviews.freebsd.org/D39269 List of files: /freebsd-14.2/sys/conf/options

Move access to tcp's t_logstate into inline functions and provide new tracepoint and bbpoint capabilities.The TCP stacks have long accessed t_logstate directly, but in order to do tracepoints and the new bbpointswe need to move to using the new inline functions.
