* cpuset(8): move to /bin/Enji Cooper2023-08-114-728/+0
| | | | | | | | | | | | | | | | | | | | | | Summary: This change moves /usr/bin/cpuset to /bin/cpuset so it is more readily available on hosts where the /usr partition might not be mounted at the time / has been mounted. Remove some complexity from rc.subr(8) since /bin is assumed to always be present if/when / is mounted. MFC after: 2 weeks MFC with: 0661f93892a2, 271d552379af Test Plan: - Test out rc.subr change. - Confirm that the installation logic does what's needed.

* Revert "cpuset: add --count"Mateusz Guzik2023-02-162-65/+2
| | | | | | | | | | | | | | | | | | | | | The patch introduced a behavior change coming from getopt_long, namely the entire argument array would be parsed looking for opts, which affected uses spawning new processes without passing '--' to delimit where cpuset arguments end. [1] Apart from that turns out the change had a bug: using CPU_LEVEL_ROOT instead of CPU_LEVEL_WHICH, returning a different cpuset than intended. [2] The intended functionality is provided with nproc(1), which landed after this change. As such, revert for the time being. This reverts commit d9d5f2c042a51a9f0dd69eb1fc349efd81ffa483.

* cpuset: add --countMateusz Guzik2023-02-042-2/+65
| | | | | | | | | | | | | | | | | | | | | | Can be used to count the number of hardware threads in the cpu set. For example: $ cpuset -g -p $$ pid 2440 mask: 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39 pid 2440 domain policy: first-touch mask: 0, 1 $ cpuset -g --count -p $$ 40 The intent is to replace calls to sysctl hw.ncpu and kern.smp.cpus which can be found in the tree, which are not adequate given existence of cpusets. Right now only -g -p combination is supported to reduce complexity. As anything else errors out, this can be expanded later as needed. Differential Revision: https://reviews.freebsd.org/D36351
* sys/bitset.h: reduce visibility of BIT_* macrosStefan Eßer2021-12-051-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add two underscore characters "__" to names of BIT_* and BITSET_* macros to move them to the implementation name space and to prevent a name space pollution due to BIT_* macros in 3rd party programs with conflicting parameter signatures. These prefixed macro names are used in kernel header files to define macros in e.g. sched.h, sys/cpuset.h and sys/domainset.h. If C programs are built with either -D_KERNEL (automatically passed when building a kernel or kernel modules) or -D_WANT_FREENBSD_BITSET (or this macros is defined in the source code before including the bitset macros), then all macros are made visible with their previous names, too. E.g., both __BIT_SET() and BIT_SET() are visible with either of _KERNEL or _WANT_FREEBSD_BITSET defined. The main reason for this change is that some 3rd party sources including sched.h have been found to contain conflicting BIT_* macros. As a work-around, parts of shed.h have been made conditional and depend on _WITH_CPU_SET_T being set when sched.h is included. Ports that expect the full functionality provided by sched.h need to be built with -D_WITH_CPU_SET_T. But this leads to conflicts if BIT_* macros are defined in that program, too. This patch set makes all of sched.h visible again without this parameter being passed and without any name space pollution due to BIT_* macros becoming visible when sched.h is included. This patch set will be backported to the STABLE branches, but ports will need to use -D_WITH_CPU_SET_T as long as there are supported releases that do not contain these patches.

* Implement several enhancements to NUMA policies.Jeff Roberson2018-03-292-6/+15
| | | | | | | | | | | | | | | | | | | | | | | | | Add a new "interleave" allocation policy which stripes pages across domains with a stride or width keeping contiguity within a multi-page region. Move the kernel to the dedicated numbered cpuset #2 making it possible to assign kernel threads and memory policy separately from user. This also eliminates the need for the complicated interrupt binding code. Add a sysctl API for viewing and manipulating domainsets. Refactor some of the cpuset_t manipulation code using the generic bitset type so that it can be used for both. This probably belongs in a dedicated subr file. Attempt to improve the include situation.

* various: general adoption of SPDX licensing ID tags.Pedro F. Giffuni2017-11-271-1/+3
| | | | | | | | | | | | | | | | | Mainly focus on files that use BSD 2-Clause license, however the tool I was using misidentified many licenses so this was mostly a manual - error prone - task. The Software Package Data Exchange (SPDX) group provides a specification to make it easier for automated tools to detect and summarize well known opensource licenses. We are gradually adopting the specification, noting that the tags are considered only advisory and do not, in any way, superceed or replace the license texts. No functional change intended.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Bring in updated jail support from bz_jail branch. This enhances the current jail implementation to permit multiple addresses per jail. In addtion to IPv4, IPv6 is supported as well. Due to updated checks it is even possible to have jails without an IP address at all, which basically gives one a chroot with restricted process view, no networking,.. SCTP support was updated and supports IPv6 in jails as well. Cpuset support permits jails to be bound to specific processor sets after creation. Jails can have an unrestricted (no duplicate protection, etc.) name in addition to the hostname. The jail name cannot be changed from within a jail and is considered to be used for management purposes or as audit-token in the future. DDB 'show jails' command was added to aid debugging. Proper compat support permits 32bit jail binaries to be used on 64bit systems to manage jails. Also backward compatibility was preserved where possible: for jail v1 syscalls, as well as with user space management utilities. Both jail as well as prison version were updated for the new features. A gap was intentionally left as the intermediate versions had been used by various patches floating around the last years. Bump __FreeBSD_version for the afore mentioned and in kernel changes. Special thanks to: - Pawel Jakub Dawidek (pjd) for his multi-IPv4 patches and Olivier Houchard (cognet) for initial single-IPv6 patches. - Jeff Roberson (jeff) and Randall Stewart (rrs) for their help, ideas and review on cpuset and SCTP support. - Robert Watson (rwatson) for lots and lots of help, discussions, suggestions and review of most of the patch at various stages. - John Baldwin (jhb) for his help. - Simon L.
