2017-12-13[XRay][compiler-rt] Reduce XRay log spamDean Michael Berris
This change makes XRay print the log file output only when the verbosity level is higher than 0. It reduces the log spam in the default case when we want XRay running silently, except when there are actual fatal/serious errors. We also update the documentation to show how to get the information after the change to the default behaviour. git-svn-id: https://llvm.org/svn/llvm-project/compiler-rt/trunk@320550 91177308-0d34-0410-b5e6-96231b3b80d8

2017-12-11[sanitizer] Introduce a vDSO aware time function, and use it in the ↵Kostya Kortchinsky
allocator [redo] Summary: Redo of D40657, which had the initial discussion. The initial code had to move into a libcdep file, and things had to be shuffled accordingly. `NanoTime` is a time sink when checking whether or not to release memory to the OS. While reducing the amount of calls to said function is in the works, another solution that was found to be beneficial was to use a timing function that can leverage the vDSO. We hit a couple of snags along the way, like the fact that the glibc crashes when clock_gettime is called from a preinit_array, or the fact that `__vdso_clock_gettime` is mangled (for security purposes) and can't be used directly, and also that clock_gettime can be intercepted. The proposed solution takes care of all this as far as I can tell, and significantly improve performances and some Scudo load tests with memory reclaiming enabled. @mcgrathr: please feel free to follow up on https://reviews.llvm.org/D40657#940857 here.

2017-12-08[libFuzzer] Add support for Fuchsia OS.Matt Morehouse
Summary: This patch adds the initial support for Fuchsia. - LIBFUZZER_FUCHSIA is added as an OS type in FuzzerDefs.h - Fuchsia is, by design, not POSIX compliant. However, it does use ELF and supports common POSIX I/O functions. Thus, FuzzerExtFunctions.h and FuzzerIO.h are implemented by extending the header guards in FuzzerExtFunctionsWeak.cpp and FuzzerIOPosix.cpp to include LIBFUZZER_FUCHSIA. - The platform-specific portions of FuzzerUtil.h are implemented by FuzzerUtilFuchsia.cpp, which makes use of exception ports, syscalls, and the launchpad library. - The experimental equivalence server is not currently supported, so FuzzerShmem.h is implemented by stub methods in FuzzerShmemFuchsia.cpp. Any future implementation will likely involve VMOs. Tested with ASAN/SanCov on Fuchsia/x86-64 with the canonical toy fuzzer.

2017-12-08[scudo] Minor code generation improvementKostya Kortchinsky
Summary: It looks like clang was generating somewhat weird assembly with the current code. `FromPrimary`, even though `const`, was replaced every time with the code generated for `size <= SizeClassMap::kMaxSize` instead of using a variable or register, and `FromPrimary` didn't induce `ClassId != 0` for the compiler, so a dead branch was generated for `getActuallyAllocatedSize(Ptr, ClassId)` since it's never called for `ClassId = 0` (Secondary backed allocations) [this one was more wishful thinking on my side than anything else]. I rearranged the code bit so that the generated assembly is less clunky. Also changed 2 whitespace inconsistencies that were bothering me.

Summary: With 3 Dictionary objects, each containing space of ~16k DictionaryEntry objects, the MutationDispatcher object is fairly memory heavy. On platforms with a lower default stack size, this can cause panics in FuzzerUnittest as those tests stack-allocate the MutationDispatcher. This may be especially problematic for platforms that do not (yet) have a way to programmatically change their stack size, aside from link-time flags. In general, it seems more prudent to use the heap for an object of this size.

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. - Allow usage of global vars with ctors in interceptors. This allows to use Vector without automatic cleaning up the structures. This code has been modeled after TSan implementation for the same functions.

Summary: Unlike the rest of the sanitizer code, lib/interception uses native macros like __linux__ to check for specific targets instead of the common ones like SANITIZER_LINUX. When working on the Solaris port of the sanitizers, the current style was found to not only be inconsistent, but clumsy to use because the canonical way to check for Solaris is to check for __sun__ && __svr4__ which is a mouthful. Therefore, this patch switches to use SANITIZER_* macros instead. Tested on x86_64-pc-linux-gnu.

The compiler can now optimize the associated computations accordingly. Also looking at the produced assembly, `PageSize` was fetched multiple times during `Allocate`, so keep a local value of it.
