2017-11-09ubsan: Allow programs to use setenv to configure ubsan_standalone.Peter Collingbourne
Previously ubsan_standalone used the GetEnv function to read the environment variables UBSAN_OPTIONS and UBSAN_SYMBOLIZER_PATH. The problem with GetEnv is that it does not respect changes to the environment variables made using the libc setenv function, which prevents clients from setting environment variables to configure ubsan before loading ubsan-instrumented libraries. The reason why we have GetEnv is that some runtimes need to read environment variables while they initialize using .preinit_array, and getenv does not work while .preinit_array functions are being called. However, it is unnecessary for ubsan_standalone to initialize that early. So this change switches ubsan_standalone to using getenv and removes the .preinit_array entry. The static version of the runtime still ends up being initialized using a C++ constructor that exists to support the shared runtime.

2017-11-08[Sanitizers, CMake] Also use version script for libclang_rt.asan-i386.soEvgeniy Stepanov

It seems the error has been hit before (cf. https://reviews.llvm.org/rL314085), but no real explanation has been found. However, the problem goes away when linking the i386 libclang_rt.asan with a version script just like every other variant is. Not using the version script in this single case dates back to the initial introduction of the version script in r236551, but this change was just checked in without any explanation AFAICT. Since I've not found any other workaround and no reason for not always using the version script, I propose to do so. Tested on x86_64-pc-linux-gnu. Patch by Rainer Orth.

2017-11-08Correct atexit(3) support in TSan/NetBSDKamil Rytarowski
Summary: The NetBSD specific implementation of cxa_atexit() does not preserve the 2nd argument if dso is equal to NULL. Changes: - Split paths of handling intercepted __cxa_atexit() and atexit(3). This affects all supported Operating Systems. - Add a local stack-like structure to hold the __cxa_atexit() context. atexit(3) is documented in the C standard as calling callback from the earliest to the oldest entry. This path also fixes potential ABI problem of passing an argument to a function from the atexit(3) callback mechanism. - Add new test to ensure LIFO style of atexit(3) callbacks: atexit3.cc Proposal to change the behavior of __cxa_atexit() in NetBSD has been rejected. With the above changes TSan/NetBSD with the current tsan_interceptors.cc can bootstrap into operation.

We allow usage of global/per-thread data with non-trivial ctors/dtors throughout tsan code base by placing all global/per-thread data into Context/ThreadState and then explicitly constructing them with placement new.

NetBSD's libpthread still calls at least pthread_mutex_lock and pthread_mutex_unlock. Detect _lwp_exit(2) call as it is really the latest operation called from a detaching POSIX thread.

2017-11-01[scudo] Implement stricter separation of C vs C++Kostya Kortchinsky
Summary: Initially, Scudo had a monolithic design where both C and C++ functions were living in the same library. This was not necessarily ideal, and with the work on -fsanitize=scudo, it became more apparent that this needed to change. We are splitting the new/delete interceptor in their own C++ library. This allows more flexibility, notably with regard to std::bad_alloc when the work is done. This also allows us to not link new & delete when using pure C. Additionally, we add the UBSan runtimes with Scudo, in order to be able to have a -fsanitize=scudo,undefined in Clang (see work in D39334). The changes in this patch: - split the cxx specific code in the scudo cmake file into a new library; (remove the spurious foreach loop, that was not necessary) - add the UBSan runtimes (both C and C++); - change the test cmake file to allow for specific C & C++ tests; - make C tests pure C, rename their extension accordingly.

2017-10-30Introduce ReservedAddressRange to sanitizer_common.Kostya Kortchinsky
Summary: Fixed version of https://reviews.llvm.org/D38437 (fixes Win/Fuchsia failures). Creating a new revision, since the old one was getting a bit old/crowded. In Fuchsia, MmapNoAccess/MmapFixedOrDie are implemented using a global VMAR, which means that MmapNoAccess can only be called once. This works for the sanitizer allocator but *not* for the Scudo allocator. Hence, this changeset introduces a new ReservedAddressRange object to serve as the new API for these calls. In this changeset, the object still calls into the old Mmap implementations. The next changeset two changesets will convert the sanitizer and scudo allocators to use the new APIs, respectively. (ReservedAddressRange will replace the SecondaryHeader in Scudo.) Finally, a last changeset will update the Fuchsia implementation.

2017-10-27[XRay][compiler-rt] Remove more STL dependenices from FDR modeDean Michael Berris
Summary: This change removes dependencies on STL types: - std::aligned_storage -- we're using manually-aligned character buffers instead for metadata and function records. - std::tuple -- use a plain old struct instead. This is an incremental step in removing all STL references from the compiler-rt implementation of XRay (llvm.org/PR32274).

2017-10-27[scudo] Allow to specify the maximum number of TSDs at compile timeKostya Kortchinsky
Summary: This introduces `SCUDO_MAX_CACHES` allowing to define an upper bound to the number of `ScudoTSD` created in the Shared TSD model (by default 32U). This name felt clearer than `SCUDO_MAX_TSDS` which is technically what it really is. I am opened to suggestions if that doesn't feel right. Additionally change `getNumberOfCPUs` to return a `u32` to be more consistent.
