We should backport the following commits: commit 6c29942cbf059aca47fd4bbd852ea42c9d46b71f Author: Stefan Liebler <stli.com> Date: Mon Feb 18 16:12:01 2019 +0100 misc/tst-clone3: Fix waiting for exited thread. From time to time the test misc/tst-clone3 fails with a timeout. Then futex_wait is blocking. Usually ctid should be set to zero due to CLONE_CHILD_CLEARTID and the futex should be waken up. But the fail occures if the thread has already exited before ctid is set to the return value of clone(). Then futex_wait() will block as there will be nobody who wakes the futex up again. This patch initializes ctid to a known value before calling clone and the kernel is the only one who updates the value to zero after clone. If futex_wait is called then it is either waked up due to the exited thread or the futex syscall fails as *ctid_ptr is already zero instead of the specified value 1. ChangeLog: * sysdeps/unix/sysv/linux/tst-clone3.c (do_test): Initialize ctid with a known value and remove update of ctid after clone. (wait_tid): Adjust arguments and call futex_wait with ctid_val as assumed current value of ctid_ptr. commit 481c30cb9573a280649fbf27251e6a0f4af1b2b1 Author: Alexandra Hájková <ahajkova> Date: Thu May 9 13:51:40 2019 +0200 elf: Add tst-ldconfig-bad-aux-cache test [BZ #18093] This test corrupts /var/cache/ldconfig/aux-cache and executes ldconfig to check it will not segfault using the corrupted aux_cache. The test uses the test-in-container framework. Verified no regressions on x86_64. commit a6c1ce778e5c05a2e6925883b410157ef47654fd Author: Alexandra Hájková <ahajkova> Date: Mon Aug 5 13:18:57 2019 +0200 elf: tst-ldconfig-bad-aux-cache: use support_capture_subprocess
