Mon, 18 May 2026 04:16:40 +0200

selftests/futex: Provide thread creation and synchronization helpersThere are timing issues in the use of threads in some selftests for futexesas the tests rely on timed waits to ensure that the other test thread[s]reached the lock wait function in the kernel.That "works" on halfways idle systems, but fails under load which resultsin tests failing.Provide a set of helper functions to create test threads and to wait forthem to reach the lock wait by monitoring /proc/$PID/wchan.[ tglx: Fixup coding style, move the timeout into the helper, adapt to test harness changes and massage change log ]Signed-off-by: Yuwen Chen Signed-off-by: Thomas Gleixner Link: https://patch.msgid.link/tencent_4C90BE98BBC48B38B9FBC6A95C45CF49F309@qq.com List of files: /linux/tools/testing/selftests/futex/functional/Makefile

90a0286c7d3591295a55c97319de322159993c21 - selftests/futex: Add FUTEX_LOCK_PI owner-exiting coverage

Sun, 07 Jun 2026 20:32:48 +0200

selftests/futex: Add FUTEX_LOCK_PI owner-exiting coverageThe futex functional tests cover FUTEX_LOCK_PI timeout semantics(futex_wait_timeout.c) and robust-list owner death (robust_list.c), butnothing exercises a non-robust PI owner exiting while holding the lock,nor the basic ownership / EDEADLK / unlock word semantics ofFUTEX_LOCK_PI.Add futex_lock_pi_exiting.c with three tests: - lock_unlock_basic: an uncontended FUTEX_LOCK_PI puts the owner TID in the futex word, a recursive lock by the owner returns EDEADLK, and FUTEX_UNLOCK_PI clears the word. - owner_dies_with_blocked_waiter: a thread acquires a PI futex and exits while holding it; a blocked FUTEX_LOCK_PI waiter must come out cleanly (0, EOWNERDEAD or ESRCH) and own the lock when it acquires. - stress_owner_exits: repeatedly drive the same exiting-owner path.The exiting-owner retry path is where commit 210d36d892de ("futex: Clearstale exiting pointer in futex_lock_pi() retry path") fixed a stale taskpointer that tripped WARN_ON_ONCE() in wait_for_owner_exiting(). Thatwarning does not change the syscall return value, so this test does notassert on it directly; the stress loop exists to give a kernel bootedwith panic_on_warn=1 (as fuzzers and CI commonly run) a chance to tripon it.Signed-off-by: Valery Borovsky Signed-off-by: Thomas Gleixner Link: https://patch.msgid.link/20260607183249.246037-1-vebohr@gmail.com List of files: /linux/tools/testing/selftests/futex/functional/Makefile
