2017-10-25Add NetBSD improvements in sanitizersKamil Rytarowski
Summary: Changes: * Add initial msan stub support. * Handle NetBSD specific pthread_setname_np(3). * NetBSD supports __attribute__((tls_model("initial-exec"))), define it in SANITIZER_TLS_INITIAL_EXEC_ATTRIBUTE. * Add ReExec() specific bits for NetBSD. * Simplify code and add syscall64 and syscall_ptr for !NetBSD. * Correct bunch of syscall wrappers for NetBSD. * Disable test/tsan/map32bit on NetBSD as not applicable. * Port test/tsan/strerror_r to a POSIX-compliant OSes. * Disable __libc_stack_end on NetBSD. * Disable ReadNullSepFileToArray() on NetBSD. * Define struct_ElfW_Phdr_sz, detected missing symbol by msan. * Change type of __sanitizer_FILE from void to char. This helps to reuse this type as an array. Long term it will be properly implemented along with SANITIZER_HAS_STRUCT_FILE setting to 1. * Add initial NetBSD support in lib/tsan/go/buildgo.sh. * Correct referencing stdout and stderr in tsan_interceptors.cc on NetBSD. * Document NetBSD x86_64 specific virtual memory layout in tsan_platform.h. * Port tests/rtl/tsan_test_util_posix.cc to NetBSD. * Enable NetBSD tests in test/msan/lit.cfg. * Enable NetBSD tests in test/tsan/lit.cfg.

This is a very poorly named feature. I think originally it meant to cover linux only, but the use of it in msan seems to be about any aarch64 platform.

Summary: Check sigset_t arguments in ppoll, sig*wait*, sigprocmask interceptors, and the entire "struct sigaction" in sigaction.

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.

This patch adds 48-bits VMA support for msan on aarch64. As current mappings for aarch64, 48-bit VMA also supports PIE executable. The 48-bits segments only cover the usual PIE/default segments plus some more segments (262144GB total, 0.39% total VMA). Memory avaliability can be increase by adding multiple application segments like 39 and 42 mapping (some mappings were added on this patch as well).
