2017-11-21Correct NetBSD support in pthread_once(3)/TSanKamil Rytarowski
Summary: The pthread_once(3)/NetBSD type is built with the following structure: struct __pthread_once_st { pthread_mutex_t pto_mutex; int pto_done; }; Set the pto_done position as shifted by __sanitizer::pthread_mutex_t_sz from the beginning of the pthread_once struct. This corrects deadlocks when the pthread_once(3) function is used.

2016-09-15[compiler-rt] Do not introduce __sanitizer namespace globallyAnna Zaks
The definitions in sanitizer_common may conflict with definitions from system headers because: The runtime includes the system headers after the project headers (as per LLVM coding guidelines). lib/sanitizer_common/sanitizer_internal_defs.h pollutes the namespace of everything defined after it, which is all/most of the sanitizer .h and .cc files and the included system headers with: using namespace __sanitizer; // NOLINT This patch solves the problem by introducing the namespace only within the sanitizer namespaces as proposed by Dmitry.

Old version of sem_init (GLIBC_2.0) fails to initialize parts of sem_t that are used in sem_timedwait.

This patch enabled msan for aarch64 with 39-bit VMA and 42-bit VMA.

So a function prototype that aims to mimic (by using first argument as the return of function) won't work. For GCC one can make a register alias (register var asm ("r8")), but for clang it detects is an unused variable and generate wrong code. The 'chained_origin_limits' is probably due a wrong code generation, since it fails only when origin memory is used (-fsanitize-memory-track-origins=2) and only in the returned code (return buf[50]). The 'signal_streess_test' and 'nonnull-arg' are due currently missing variadic argument handling in memory sanitizer code instrumentation on LLVM side. Both 'dlerror' and 'param_tls_test' are unknown failures that require further investigation. All the failures are XFAIL for aarch64 for now. git-svn-id: https://llvm.org/svn/llvm-project/compiler-rt/trunk@247809 91177308-0d34-0410-b5e6-96231b3b80d8

2015-02-24Allow sanitizer to work with "old" kernel headersRenato Golin
Sanitizers work on ancient kernels and were depending on types existing. When those types were removed, the sanitizer build broke. See bug https://gcc.gnu.org/bugzilla/show_bug.cgi?id=59009 for more information. This patch fixes it by isolating the need for those types only when the feature is actually needed, thus allowing one to compile the kernel with or without that change, irrespective of its version.

This patch allows to build against the recent glibc and disables the ipc_perm.mode verification for older versions of glibc.
