2017-09-15ubsan: Unbreak ubsan_cxx runtime library on Windows.Peter Collingbourne
This was originally broken by r258744 which introduced a weak reference from ubsan to ubsan_cxx. This reference does not work directly on Windows because COFF has no direct concept of weak symbols. The fix is to use /alternatename to create a weak external reference to ubsan_cxx. Also fix the definition (and the name, so that we drop cached values) of the cmake flag that controls whether to build ubsan_cxx. Now the user-controllable flag is always on, and we turn it off internally depending on whether we support building it.

2017-09-15[sanitizer][mips64] fix MIPS64 kernel_stat_to_stat()Petar Jovanovic
This patch tackles with two issues: Output stat st_[a|m|c]time fields were holding wrong values. st_[a|m|c]time fields should have contained value of seconds and instead these are filled with st_[a|m|c]time_nsec fields which hold nanoseconds. Build fails for MIPS64 if SANITIZER_ANDROID. Recently <sys/stat.h> from bionic introduced st_[a|m|c]time_nsec macros for compatibility with old NDKs and those clashed with the field names of the <asm/stat.h> kernel_stat structure. To fix both issues and make sure sanitizer builds on all platforms, we must un-define all compatibility macros and access the fields directly when copying the 'time' fields.

2017-09-14[scudo] Fix bad request handling when allocator has not been initializedKostya Kortchinsky
Summary: In a few functions (`scudoMemalign` and the like), we would call `ScudoAllocator::FailureHandler::OnBadRequest` if the parameters didn't check out. The issue is that if the allocator had not been initialized (eg: if this is the first heap related function called), we would use variables like `allocator_may_return_null` and `exitcode` that still had their default value (as opposed to the one set by the user or the initialization path). To solve this, we introduce `handleBadRequest` that will call `initThreadMaybe`, allowing the options to be correctly initialized. Unfortunately, the tests were passing because `exitcode` was still 0, so the results looked like success. Change those tests to do what they were supposed to.

2017-09-11[scudo] Fix improper TSD init after TLS destructors are calledKostya Kortchinsky
Summary: Some of glibc's own thread local data is destroyed after a user's thread local destructors are called, via __libc_thread_freeres. This might involve calling free, as is the case for strerror_thread_freeres. If there is no prior heap operation in the thread, this free would end up initializing some thread specific data that would never be destroyed properly (as user's pthread destructors have already been called), while still being deallocated when the TLS goes away. As a result, a program could SEGV, usually in __sanitizer::AllocatorGlobalStats::Unregister, where one of the doubly linked list links would refer to a now unmapped memory area. To prevent this from happening, we will not do a full initialization from the deallocation path. This means that the fallback cache & quarantine will be used if no other heap operation has been called, and we effectively prevent the TSD being initialized and never destroyed. The TSD will be fully initialized for all other paths. In the event of a thread doing only frees and nothing else, a TSD would never be initialized for that thread, but this situation is unlikely and we can live with that.
