I've cherry-picked following fix from llvm-project. Recent glibcs have _thread_db_sizeof_pthread symbol variable which contains the size of struct pthread, so that sanitizers don't need to guess that and risk that it will change again. 2022-02-15 Jakub Jelinek <jakub@redhat.com> * sanitizer_common/sanitizer_linux_libcdep.cpp: Cherry-pick llvm-project revision ef14b78d9a144ba81ba02083fe21eb286a88732b.

Bump asan/tsan versions for upstream commits: commit f1bb30a4956f83e46406d6082e5d376ce65391e0 Author: Vitaly Buka <vitalybuka@google.com> Date: Thu Aug 26 10:25:09 2021 -0700 [sanitizer] No THREADLOCAL in qsort and bsearch qsort can reuse qsort_r if available. bsearch always passes key as the first comparator argument, so we can use it to wrap the original comparator. Differential Revision: https://reviews.llvm.org/D108751 commit d77b476c1953bcb0a608b2d6a4f2dd9fe0b43967 Author: Dmitry Vyukov <dvyukov@google.com> Date: Mon Aug 2 16:52:53 2021 +0200 tsan: avoid extra call indirection in unaligned access functions Currently unaligned access functions are defined in tsan_interface.cpp and do a real call to MemoryAccess. This means we have a real call and no read/write constant propagation. Unaligned memory access can be quite hot for some programs (observed on some compression algorithms with ~90% of unaligned accesses). Move them to tsan_interface_inl.h to avoid the additional call and enable constant propagation. Also reorder the actual store and memory access handling for __sanitizer_unaligned_store callbacks to enable tail calling in MemoryAccess. Depends on D107282. Reviewed By: vitalybuka, melver commit 97795be22f634667ce7a022398c59ccc9f7440eb Author: Dmitry Vyukov <dvyukov@google.com> Date: Fri Jul 30 08:35:11 2021 +0200 tsan: optimize test-only barrier The updated lots_of_threads.c test with 300 threads started running for too long on machines with low hardware parallelism (e.g. taskset -c 0-1). On lots of CPUs it finishes in ~2 secs. But with taskset -c 0-1 it runs for hundreds of seconds effectively spinning in the barrier in the sleep loop. We now have the handy futex API in sanitizer_common. Use it instead of the passive spin loop. It makes the test run only faster with taskset -c 0-1, it runs for ~1.5 secs, while with full parallelism it still runs for ~2 secs (but consumes less CPU time). Depends on D107131.

2021-08-11sanitizer: Cherry-pick realpath fixJakub Jelinek1-11/+1
tsan in some cases starts ignoring interceptors and only calls the intercepted functions. But for realpath the behavior for NULL second argument was only handled in the interceptor and intercepted function was the one found by dlsym which is often one that doesn't handle NULL as second argument. Fixed by using dlvsym with "GLIBC_2.3" if possible for intercepted function and don't emulate behavior in the wrapper. 2021-08-11 Jakub Jelinek <jakub@redhat.com> * sanitizer_common/sanitizer_common_interceptors.inc: Cherry-pick llvm-project revision faef0d042f523357fe5590e7cb6a8391cf0351a8.
