4793cb59 - selftests: cgroup: skip test_cgcore_lesser_ns_open when cgroup2 mounted without nsdelegate

Wed, 27 Mar 2024 02:44:37 +0000

selftests: cgroup: skip test_cgcore_lesser_ns_open when cgroup2 mounted without nsdelegateThe test case test_cgcore_lesser_ns_open only tasks effect when cgroup2is mounted with "nsdelegate" mount option. If it misses this option, oris remounted without "nsdelegate", the test case will fail. For example,running bpf/test_cgroup_storage first, and then run cgroup/test_core willfail on test_cgcore_lesser_ns_open. Skip it if "nsdelegate" is notdetected in cgroup2 mount options.Fixes: bf35a7879f1d ("selftests: cgroup: Test open-time cgroup namespace usage for migration checks")Signed-off-by: Tianchen Ding Reviewed-by: Muhammad Usama Anjum Signed-off-by: Tejun Heo List of files: /linux-6.15/tools/testing/selftests/cgroup/test_core.c

kselftest/cgroup: add cgroup destruction testAdd new test to verify that a cgroup with dead processes can be destroyed.The test spawns a child process which allocates and touches 100MB of RAMto ensure prolonged exit. Subsequently it kills the child, waits untilthe cgroup containing the child is empty and destroys the cgroup.Signed-off-by: Suren Baghdasaryan [mkoutny@suse.com: Fix typo in test_cgcore_destroy comment]Acked-by: Michal Koutný Signed-off-by: Michal Koutný Signed-off-by: Tejun Heo List of files: /linux-6.15/tools/testing/selftests/cgroup/test_core.c

d863cb03 - Add cgroup core selftests

Wed, 18 Jul 2018 17:33:58 +0000

Add cgroup core selftestsThis commit adds tests for some of the core functionalitiesof cgroups v2.The commit adds tests for some core principles of croup V2 API:- test_cgcore_internal_process_constraint Tests internal process constraint. You can't add a pid to a domain parent if a controller is enabled.- test_cgcore_top_down_constraint_enable Tests that you can't enable a controller on a child if it's not enabled on the parent.- test_cgcore_top_down_constraint_disable Tests that you can't disable a controller on a parent if it's enabled in a child.- test_cgcore_no_internal_process_constraint_on_threads Tests that there's no internal process constrain on threaded cgroups. You can add threads/processes on a parent with a controller enabled.- test_cgcore_parent_becomes_threaded Tests that when a child becomes threaded the parent type becomes domain threaded.- test_cgcore_invalid_domain In a situation like: A (domain threaded) - B (threaded) - C (domain) it tests that C can't be used until it is turned into a threaded cgroup. The "cgroup.type" file will report "domain (invalid)" in these cases. Operations which fail due to invalid topology use EOPNOTSUPP as the errno.- test_cgcore_populated In a situation like: A(0) - B(0) - C(1) \ D(0) It tests that A, B and C's "populated" fields would be 1 while D's 0. It tests that after the one process in C is moved to root, A,B and C's "populated" fields would flip to "0" and file modified events will be generated on the "cgroup.events" files of both cgroups.Signed-off-by: Claudio Zumbo Cc: Shuah Khan Cc: Roman Gushchin Cc: Tejun Heo Cc: kernel-team@fb.comAcked-by: Tejun Heo Reviewed-by: Roman Gushchin Signed-off-by: Shuah Khan (Samsung OSG) List of files: /linux-6.15/tools/testing/selftests/cgroup/test_core.c
