[PATCH] kselftests/net: adapt the timeout to the largest runtime

by Li Zhijian

timeout in settings is used by each case under the same directory, so it should adapt to the maximum runtime. A normally running net/fib_nexthops.sh may be killed by this unsuitable timeout. Furthermore, since the defect[1] of kselftests framework, net/fib_nexthops.sh which might take at least (300 * 4) seconds would block the whole kselftests framework previously. $ git grep -w 'sleep 300' tools/testing/selftests/net tools/testing/selftests/net/fib_nexthops.sh: sleep 300 tools/testing/selftests/net/fib_nexthops.sh: sleep 300 tools/testing/selftests/net/fib_nexthops.sh: sleep 300 tools/testing/selftests/net/fib_nexthops.sh: sleep 300 Enlarge the timeout by plus 300 based on the obvious largest runtime to avoid the blocking.

[PATCH v2] ksefltest: pidfd: Fix wait_states: Test terminated by timeout

by Li Zhijian

0Day/LKP observed that the kselftest blocks foever since one of the pidfd_wait doesn't terminate in 1 of 30 runs. After digging into the source, we found that it blocks at: ASSERT_EQ(sys_waitid(P_PIDFD, pidfd, &info, WCONTINUED, NULL), 0); we can reproduce it by: $ while true; do make run_tests -C pidfd; done Introduce a blocking read in child process to make sure the parent can check its WCONTINUED.

[PATCH v9 0/7] cgroup/cpuset: Add new cpuset partition type & empty effecitve cpus

by Waiman Long

v9: - Add a new patch 1 to remove the child cpuset restriction on parent's "cpuset.cpus". - Relax initial root partition entry limitation to allow cpuset.cpus to overlap that of parent's. - An "isolated invalid" displayed type is added to cpuset.cpus.partition. - Resetting partition root to "member" will leave child partition root as invalid. - Update documentation and test accordingly. v8: - Reorganize the patch series and rationalize the features and constraints of a partition. - Update patch descriptions and documentation accordingly. v7: - Simplify the documentation patch (patch 5) as suggested by Tejun. - Fix a typo in patch 2 and improper commit log in patch 3. This patchset includes one bug fix and four enhancements to the cpuset v2 code. Patch 1: Allow parent to set "cpuset.cpus" that may not be a superset of children's "cpuset.cpus" for default hierarchy. Patch 2: Enable partition with no task to have empty cpuset.cpus.effective. Patch 3: Refining the features and constraints of a cpuset partition clarifying what changes are allowed. Patch 4: Add a new partition state "isolated" to create a partition root without load balancing. This is for handling intermitten workloads that have a strict low latency requirement. Patch 5: Enable the "cpuset.cpus.partition" file to show the reason that causes invalid partition like "root invalid (No cpu available due to hotplug)". Patch 6 updates the cgroup-v2.rst file accordingly. Patch 7 adds a new cpuset test to test the new cpuset partition code. Waiman Long (7): cgroup/cpuset: Don't let child cpusets restrict parent in default hierarchy cgroup/cpuset: Allow no-task partition to have empty cpuset.cpus.effective cgroup/cpuset: Refining features and constraints of a partition cgroup/cpuset: Add a new isolated cpus.partition type cgroup/cpuset: Show invalid partition reason string cgroup/cpuset: Update description of cpuset.cpus.partition in cgroup-v2.rst kselftest/cgroup: Add cpuset v2 partition root state test Documentation/admin-guide/cgroup-v2.rst | 168 +++-- kernel/cgroup/cpuset.c | 440 +++++++----- tools/testing/selftests/cgroup/Makefile | 5 +- .../selftests/cgroup/test_cpuset_prs.sh | 667 ++++++++++++++++++ tools/testing/selftests/cgroup/wait_inotify.c | 87 +++ 5 files changed, 1142 insertions(+), 225 deletions(-) create mode 100755 tools/testing/selftests/cgroup/test_cpuset_prs.sh create mode 100644 tools/testing/selftests/cgroup/wait_inotify.c -- 2.27.0

[PATCH] selftests: rtc: Increase test timeout so that all tests run

by Nícolas F. R. A. Prado

The timeout setting for the rtc kselftest is currently 90 seconds. However, two of the tests set alarms, which take one minute to complete each. So the timeout should be at least 120. Set it to 180, so that all tests are able to complete and still have some slack. Signed-off-by: Nícolas F. R. A. Prado <nfraprado(a)collabora.com> --- This issue was discovered as part of adding the rtc kselftest to run on KernelCI for the rk3399-gru-kevin device, which uses rtc-cros-ec as the RTC driver. The output log with the current timeout is shown in [1]. As can be seen, the whole test times out before the alarm_wkalm_set_minute test has had a chance to complete: # # RUN rtc.alarm_wkalm_set_minute ... # # rtctest.c:294:alarm_wkalm_set_minute:Alarm time now set to 11/01/2022 23:03:00. # not ok 1 selftests: rtc: rtctest # TIMEOUT 90 seconds With the increased timeout, as shown in [2], the alarm_wkalm_set_minute test does complete its run: # # RUN rtc.alarm_wkalm_set_minute ... # # rtctest.c:294:alarm_wkalm_set_minute:Alarm time now set to 12/01/2022 15:54:00. # # OK rtc.alarm_wkalm_set_minute # ok 7 rtc.alarm_wkalm_set_minute # # FAILED: 6 / 7 tests passed. The fact that the alarm_alm_set_minute test times out on its own is probably an issue with the rtc-cros-ec driver. Still, since the tests are independent, all of them should be able to run regardless of how long each one takes (so, assuming the worst case scenario).
