2018-07-24[tsan] Fix crash in objc_sync_enter/objc_sync_exit when using an Obj-C ↵Kuba Mracek
tagged pointer Objective-C tagged pointers (either bottom-most or top-most bit is 1) are valid Obj-C objects but are not valid pointers. Make sure we don't crash on them when used in objc_sync_enter/objc_sync_exit. Instead, let's synchronize on a global object.

2018-07-10[compiler-rt] Get rid of "%T" expansionsFilipe Cabecinhas
Summary: Original patch by Kuba Mracek The %T lit expansion expands to a common directory shared between all the tests in the same directory, which is unexpected and unintuitive, and more importantly, it's been a source of subtle race conditions and flaky tests. In https://reviews.llvm.org/D35396, it was agreed that it would be best to simply ban %T and only keep %t, which is unique to each test. When a test needs a temporary directory, it can just create one using mkdir %t. This patch removes %T in compiler-rt.

2018-06-18[TSan] Report proper error on allocator failures instead of CHECK(0)-ingAlex Shlyapnikov
Summary: Following up on and complementing D44404 and other sanitizer allocators. Currently many allocator specific errors (OOM, for example) are reported as a text message and CHECK(0) termination, no stack, no details, not too helpful nor informative. To improve the situation, detailed and structured common errors were defined and reported under the appropriate conditions. Common tests were generalized a bit to cover a slightly different TSan stack reporting format, extended to verify errno value and returned pointer value check is now explicit to facilitate debugging.

Given that this is the second occurance of this problem it seemed worth fixing this problem in a more generic way. r328775 has been reverted and now a substitution `%linux_static_libstdcplusplus` has been provided.

1. Allow to suppress by current stack. We generally allow to suppress by all main stacks. Current is probably the stack one wants to use to suppress such reports. 2. Fix last lock stack restoration.

Objective-C's @synchronize synchronization primitive uses calls to objc_sync_enter and objc_sync_exit runtime functions. In most cases, they end up just calling pthread_mutex_lock/pthread_mutex_unlock, but there are some cases where the synchronization from pthread_mutex_lock/pthread_mutex_unlock interceptors isn't enough. Let's add explicit interceptors for objc_sync_enter and objc_sync_exit to handle all cases.

There was a failure on a bot: http://lab.llvm.org:8011/builders/clang-cmake-mipsel/builds/1283 strerror test is indeed flaky. We protect all races by a barrier in other tests to eliminate flakiness. Do the same here. No idea why tls_race2.cc failed. Add output at the end of the test as we do in other tests. Sometimes test process crashes somewhere in the middle (e.g. during race reporting) and it looks like empty output. Output at the end of test allows to understand if the process has crashed, or it has finished but produced no race reports.

The current implementation of commands in `test/sanitizer_common/ios_commands/` for iOS devices cannot be executed in parallel which results in the ASan and TSan tests failing when executed in parallel by lit which was the default behaviour. We now force the ASan and TSan tests to be a new parallelism group named `darwin-ios-device-sanitizer` which allows only one test to be run at a time. We also emit a warning informing the user that tests are being run sequentially. This only applies if the target is an iOS device.

Summary: As discussed in https://github.com/google/oss-fuzz/issues/933, it would be really awesome to be able to use ThinLTO for fuzzing. However, as @kcc has pointed out, it is currently undefined (untested) whether the sanitizers actually function properly with LLD and/or LTO. This patch is inspired by the cfi test, which already do test with LTO (and/or LLD), since LTO is required for CFI to function. I started with UBSan, because it's cmakelists / lit.* files appeared to be the cleanest. This patch adds the infrastructure to easily add LLD and/or LTO sub-variants of the existing lit test configurations. Also, this patch adds the LLD flavor, that explicitly does use LLD to link. The check-ubsan does pass on my machine. And to minimize the [initial] potential buildbot breakage i have put some restrictions on this flavour. Please review carefully, i have not worked with lit/sanitizer tests before. The original attempt, r319525 was reverted in r319526 due to the failures in compiler-rt standalone builds.

2017-10-20[tsan] Add Mutex annotation flag for constant-initialized ↵Dmitry Vyukov
__tsan_mutex_linker_init behavior Add a new flag, _⁠_tsan_mutex_not_static, which has the opposite sense of _⁠_tsan_mutex_linker_init. When the new _⁠_tsan_mutex_not_static flag is passed to _⁠_tsan_mutex_destroy, tsan ignores the destruction unless the mutex was also created with the _⁠_tsan_mutex_not_static flag. This is useful for constructors that otherwise woud set _⁠_tsan_mutex_linker_init but cannot, because they are declared constexpr. Google has a custom mutex with two constructors, a "linker initialized" constructor that relies on zero-initialization and sets ⁠_⁠_tsan_mutex_linker_init, and a normal one which sets no tsan flags. The "linker initialized" constructor is morally constexpr, but we can't declare it constexpr because of the need to call into tsan as a side effect. With this new flag, the normal c'tor can set _⁠_tsan_mutex_not_static, the "linker initialized" constructor can rely on tsan's lazy initialization, and _⁠_tsan_mutex_destroy can still handle both cases correctly.

2017-07-24[Sanitizers] TSan allocator set errno on failure.Alex Shlyapnikov
Summary: Set proper errno code on allocation failures and change realloc, pvalloc, aligned_alloc, memalign and posix_memalign implementation to satisfy their man-specified requirements. Modify allocator API implementation to bring it closer to other sanitizers allocators.

2017-07-05[tsan] Use pthread_sigmask instead of sigprocmask to block signals in a ↵Kuba Mracek
thread on Darwin On Darwin, sigprocmask changes the signal mask for the entire process. This has some unwanted consequences, because e.g. internal_start_thread wants to disable signals only in the current thread (to make the new thread inherit the signal mask), which is currently broken on Darwin. This patch switches to pthread_sigmask.

2017-06-28[Sanitizers] Operator new() interceptors always die on allocation errorAlex Shlyapnikov
Summary: Operator new interceptors behavior is now controlled by their nothrow property as well as by allocator_may_return_null flag value: - allocator_may_return_null=* + new() - die on allocation error - allocator_may_return_null=0 + new(nothrow) - die on allocation error - allocator_may_return_null=1 + new(nothrow) - return null Ideally new() should throw std::bad_alloc exception, but that is not trivial to achieve, hence TODO.
