fbf4dec7 - selftests/futex: Order calls to futex_lock_pi

Mon, 14 Aug 2023 08:09:27 +0000

selftests/futex: Order calls to futex_lock_piObserved occassional failures in the futex_wait_timeout test:ok 1 futex_wait relative succeedsok 2 futex_wait_bitset realtime succeedsok 3 futex_wait_bitset monotonic succeedsok 4 futex_wait_requeue_pi realtime succeedsok 5 futex_wait_requeue_pi monotonic succeedsnot ok 6 futex_lock_pi realtime returned 0......The test expects the child thread to complete some steps beforethe parent thread gets to run. There is an implicit expectationof the order of invocation of futex_lock_pi between the child threadand the parent thread. Make this order explicit. If the order isnot met, the futex_lock_pi call in the parent thread succeeds andwill not timeout.Fixes: f4addd54b161 ("selftests: futex: Expand timeout test")Signed-off-by: Nysal Jan K.A Signed-off-by: Shuah Khan List of files: /linux-6.15/tools/testing/selftests/futex/functional/futex_wait_timeout.c

1f666e52 - selftests: futex: print testcase-name and PASS/FAIL/ERROR status

Mon, 22 May 2017 07:17:43 +0000

selftests: futex: print testcase-name and PASS/FAIL/ERROR statusMost of the tests under selftests follow a pattern for their results,which can then be parsed easily by other external tools easily. Thoughfutex tests do print the test results very well, it doesn't reallyfollow the general selftests pattern.This patch makes necessary changes to fix that.Output before this patch:futex_requeue_pi: Test requeue functionality Arguments: broadcast=0 locked=0 owner=0 timeout=0nsResult: PASSOutput after this patch:futex_requeue_pi: Test requeue functionality Arguments: broadcast=0 locked=0 owner=0 timeout=0nsselftests: futex-requeue-pi [PASS]Signed-off-by: Naresh Kamboju Signed-off-by: Shuah Khan List of files: /linux-6.15/tools/testing/selftests/futex/functional/futex_wait_timeout.c

2aa8470f - selftests: Add futex functional tests

Wed, 13 May 2015 04:07:52 +0000

selftests: Add futex functional testsThe futextest testsuite [1] provides functional, stress, andperformance tests for the various futex op codes. Those tests will be ofmore use to futex developers if they are included with the kernelsource.Copy the core infrastructure and the functional tests into selftests,but adapt them for inclusion in the kernel:- Update the Makefile to include the run_tests target, remove reference to the performance and stress tests from the contributed sources.- Replace my dead IBM email address with my current Intel email address.- Remove the warrantee and write-to paragraphs from the license blurbs.- Remove the NAME section as the filename is easily determined. ;-)- Make the whitespace usage consistent in a couple of places.- Cleanup various CodingStyle violations.A future effort will explore moving the performance and stress testsinto the kernel.1. http://git.kernel.org/cgit/linux/kernel/git/dvhart/futextest.gitCc: Shuah Khan Cc: linux-api@vger.kernel.orgCc: Ingo Molnar Cc: Peter Zijlstra Cc: Thomas Gleixner Cc: Davidlohr Bueso Cc: KOSAKI Motohiro Signed-off-by: Darren Hart Signed-off-by: Shuah Khan List of files: /linux-6.15/tools/testing/selftests/futex/functional/futex_wait_timeout.c
