afec9538 - [sanitizer] Simplify GetTls with dl_iterate_phdr on Linux and use it on musl/FreeBSD

Thu, 15 Apr 2021 22:34:43 +0000

[sanitizer] Simplify GetTls with dl_iterate_phdr on Linux and use it on musl/FreeBSD... so that FreeBSD specific GetTls/glibc specific pthread_self code can beremoved. This also helps FreeBSD arm64/powerpc64 which don't have GetTlsimplementation yet.GetTls is the range of* thread control block and optional TLS_PRE_TCB_SIZE* static TLS blocks plus static TLS surplusOn glibc, lsan requires the range to include`pthread::{specific_1stblock,specific}` so that allocations only referenced by`pthread_setspecific` can be scanned.This patch uses `dl_iterate_phdr` to collect TLS blocks. Find the onewith `dlpi_tls_modid==1` as one of the initially loaded module, then findconsecutive ranges. The boundaries give us addr and size.This allows us to drop the glibc internal `_dl_get_tls_static_info` and`InitTlsSize`. However, huge glibc x86-64 binaries with numerous shared objectsmay observe time complexity penalty, so exclude them for now. Use the simplifiedmethod with non-Android Linux for now, but in theory this can be used with *BSDand potentially other ELF OSes.This removal of RISC-V `__builtin_thread_pointer` makes the code compilable withmore compiler versions (added in Clang in 2020-03, added in GCC in 2020-07).This simplification enables D99566 for TLS Variant I architectures.Note: as of musl 1.2.2 and FreeBSD 12.2, dlpi_tls_data returned bydl_iterate_phdr is not desired: https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=254774This can be worked around by using `__tls_get_addr({modid,0})` insteadof `dlpi_tls_data`. The workaround can be shared with the workaround for glibc<2.25.This fixes some tests on Alpine Linux x86-64 (musl)```test/lsan/Linux/cleanup_in_tsd_destructor.ctest/lsan/Linux/fork.cpptest/lsan/Linux/fork_threaded.cpptest/lsan/Linux/use_tls_static.cpptest/lsan/many_tls_keys_thread.cpptest/msan/tls_reuse.cpp```and `test/lsan/TestCases/many_tls_keys_pthread.cpp` on glibc aarch64.The number of sanitizer test failures does not change on FreeBSD/amd64 12.2.Differential Revision: https://reviews.llvm.org/D98926 List of files: /llvm-project-15.0.7/compiler-rt/test/lsan/TestCases/many_tls_keys_pthread.cpp

[lsan][test] Disable many_tls_keys_pthread.cpp on AArch64Partially reverts 04dbb63400c5fa2f263d7473272509be572a367a.This test requires 9be8f8b34d9b150cd1811e3556fe9d0cd735ae29which is/has been reverted a few times but this test wasleft enabled.Currently that change is reverted and this test is failing:http://lab.llvm.org:8011/#/builders/7/builds/2327 List of files: /llvm-project-15.0.7/compiler-rt/test/lsan/TestCases/many_tls_keys_pthread.cpp

04dbb634 - [lsan][test] Enable many_tls_keys_pthread.cpp and disable swapcontext.cpp/fork_and_leak.cpp

[lsan][test] Enable many_tls_keys_pthread.cpp and disable swapcontext.cpp/fork_and_leak.cppWith D98926, many_tls_keys_pthread.cpp appears to be working.On glibc 2.30-0ubuntu2, swapcontext.cpp and Linux/fork_and_leak.cpp work finebut they strangely fail on clang-cmake-aarch64-full(https://lab.llvm.org/buildbot/#/builders/7/builds/2240).Disable them for now.Note: check-lsan was recently enabled on AArch64 in D98985. A test takes10+ seconds. We should figure out the bottleneck. List of files: /llvm-project-15.0.7/compiler-rt/test/lsan/TestCases/many_tls_keys_pthread.cpp
