fe3b1bf1 - selftests: cgroup: add test_zswap program

Wed, 21 Jun 2023 15:35:46 +0000

selftests: cgroup: add test_zswap programPatch series "selftests: cgroup: add zswap test program".This series adds 2 zswap related selftests that verify known and fixedissues. A new dedicated test program (test_zswap) is proposed since thetest cases are specific to zswap and hosts specific helpers.The first patch adds the (empty) test program, while the other 2 add anactual test function each.This patch (of 3):Add empty cgroup-zswap self test scaffold program, test functions to beadded in the next commits.Link: https://lkml.kernel.org/r/20230621153548.428093-1-cerasuolodomenico@gmail.comLink: https://lkml.kernel.org/r/20230621153548.428093-2-cerasuolodomenico@gmail.comSigned-off-by: Domenico Cerasuolo Cc: Dan Streetman Cc: Johannes Weiner Cc: Michal Hocko Cc: Muchun Song Cc: Nhat Pham Cc: Rik van Riel Cc: Roman Gushchin Cc: Seth Jennings Cc: Shakeel Butt Cc: Shuah Khan Cc: Tejun Heo Cc: Vitaly Wool Cc: Zefan Li Signed-off-by: Andrew Morton List of files: /linux-6.15/tools/testing/selftests/cgroup/.gitignore

selftests: cgroup: Add cpuset migrations testcaseAdd a separate testfile to verify treating permissions when tasks aremigrated on cgroup v2 hierarchy between cpuset cgroups.In accordance with v2 design, migration should be allowed based ondelegation boundaries (i.e. cgroup.procs permissions) and does notdepend on the migrated object (i.e. unprivileged process can migrateanother process (even privileged) as long as it remains in the originaldedicated scope).Signed-off-by: Michal Koutný Signed-off-by: Tejun Heo List of files: /linux-6.15/tools/testing/selftests/cgroup/.gitignore

820a4f88 - cgroup: Add new test_cpu.c test suite in cgroup selftests

Fri, 22 Apr 2022 17:33:49 +0000

cgroup: Add new test_cpu.c test suite in cgroup selftestsThe cgroup selftests suite currently contains tests that validate variousaspects of cgroup, such as validating the expected behavior for memorycontrollers, the expected behavior of cgroup.procs, etc. There are no teststhat validate the expected behavior of the cgroup cpu controller.This patch therefore adds a new test_cpu.c file that will contain cpucontroller testcases. The file currently only contains a single testcasethat validates creating nested cgroups with cgroup.subtree_controlincluding cpu. Future patches will add more sophisticated testcases thatvalidate functional aspects of the cpu controller.Signed-off-by: David Vernet Signed-off-by: Tejun Heo List of files: /linux-6.15/tools/testing/selftests/cgroup/.gitignore

933dc80e - kselftests: cgroup: add kernel memory accounting tests

Fri, 07 Aug 2020 06:21:30 +0000

kselftests: cgroup: add kernel memory accounting testsAdd some tests to cover the kernel memory accounting functionality. Theseare covering some issues (and changes) we had recently.1) A test which allocates a lot of negative dentries, checks memcg slab statistics, creates memory pressure by setting memory.max to some low value and checks that some number of slabs was reclaimed.2) A test which covers side effects of memcg destruction: it creates and destroys a large number of sub-cgroups, each containing a multi-threaded workload which allocates and releases some kernel memory. Then it checks that the charge ans memory.stats do add up on the parent level.3) A test which reads /proc/kpagecgroup and implicitly checks that it doesn't crash the system.4) A test which spawns a large number of threads and checks that the kernel stacks accounting works as expected.5) A test which checks that living charged slab objects are not preventing the memory cgroup from being released after being deleted by a user.Signed-off-by: Roman Gushchin Signed-off-by: Andrew Morton Cc: Christoph Lameter Cc: Johannes Weiner Cc: Michal Hocko Cc: Shakeel Butt Cc: Tejun Heo Cc: Vlastimil Babka Link: http://lkml.kernel.org/r/20200623174037.3951353-19-guro@fb.comSigned-off-by: Linus Torvalds List of files: /linux-6.15/tools/testing/selftests/cgroup/.gitignore

5313bfe4 - kselftests: cgroup: add freezer controller self-tests

Fri, 19 Apr 2019 17:03:06 +0000

kselftests: cgroup: add freezer controller self-testsThis patch implements 9 tests for the freezer controller forcgroup v2:1) a simple test, which aims to freeze and unfreeze a cgroup with 100processes2) a more complicated tree test, which creates a hierarchy of cgroups,puts some processes in some cgroups, and tries to freeze and unfreezedifferent parts of the subtree3) a forkbomb test: the test aims to freeze a forkbomb running in acgroup, kill all tasks in the cgroup and remove the cgroup withoutthe unfreezing.4) rmdir test: the test creates two nested cgroups, freezes the parentone, checks that the child can be successfully removed, and a newchild can be created5) migration tests: the test checks migration of a task betweenfrozen cgroups: from a frozen to a running, from a running to afrozen, and from a frozen to a frozen.6) ptrace test: the test checks that it's possible to attach toa process in a frozen cgroup, get some information and detach, andthe cgroup will remain frozen.7) stopped test: the test checks that it's possible to freeze a cgroupwith a stopped task8) ptraced test: the test checks that it's possible to freeze a cgroupwith a ptraced task9) vfork test: the test checks that it's possible to freeze a cgroupwith a parent process waiting for the child process in vfork()Expected output: $ ./test_freezer ok 1 test_cgfreezer_simple ok 2 test_cgfreezer_tree ok 3 test_cgfreezer_forkbomb ok 4 test_cgrreezer_rmdir ok 5 test_cgfreezer_migrate ok 6 test_cgfreezer_ptrace ok 7 test_cgfreezer_stopped ok 8 test_cgfreezer_ptraced ok 9 test_cgfreezer_vforkSigned-off-by: Roman Gushchin Signed-off-by: Tejun Heo Cc: Shuah Khan Cc: kernel-team@fb.comCc: linux-kselftest@vger.kernel.org List of files: /linux-6.15/tools/testing/selftests/cgroup/.gitignore
