2015-02-06[compiler-rt] Make MaybeReexec properly process DYLD_INSERT_LIBRARIES when ↵Kuba Brecka
using non-absolute paths MaybeReexec() in asan_mac.cc checks for presence of the ASan dylib in DYLD_INSERT_LIBRARIES, and if it is there, it will process this env. var. and remove the dylib from its value, so that spawned children don't have this variable set. However, the current implementation only works when using a canonical absolute path to the dylib, it fails to remove the dylib for example when using @executable_path. This patch changes the processing of DYLD_INSERT_LIBRARIES to comparing values only based on filenames (ignoring directories).

2015-01-23[compiler-rt] Ensure AsanInitFromRtl is called from a static initializer on ↵Kuba Brecka
OS X by using ASAN_DYNAMIC=1 The idea is to ensure that the ASan runtime gets initialized early (i.e. before other initializers/constructors) even when DYLD_INSERT_LIBRARIES is not used. In that case, the interceptors are not installed (on OS X, DYLD_INSERT_LIBRARIES is required for interceptors to work), and therefore ASan gets currently initialized quite late -- from the main executable's module initializer. The following issues are a consequence of this: https://code.google.com/p/address-sanitizer/issues/detail?id=363 https://code.google.com/p/address-sanitizer/issues/detail?id=357 Both of them are fixed with this patch.

2015-01-22Fix/workaround for OS X truncated stacktraces taken by external toolsKuba Brecka
This patch is a proposed solution for https://code.google.com/p/address-sanitizer/issues/detail?id=375: When the stacktraces are captured and printed by ASan itself, they are fine, but when the program has already printed the report (or is just printing it), capturing a stacktrace via other means is broken. "Other means" include OS X CrashReporter, debuggers or calling backtrace() within the program. For example calling backtrace() from a sanitizer_set_death_callback function prints a very truncated stacktrace.

2015-01-21[msan] Fix origins in realloc.Evgeniy Stepanov
Fixes 2 issues in origins arising from realloc() calls: * In the in-place grow case origin for the new memory is not set at all. * In the copy-realloc case __msan_memcpy is used, which unwinds stack from inside the MSan runtime. This does not generally work (as we may be built w/o frame pointers), and produces "bad" stack trace anyway, with several uninteresting (internal) frames on top. This change also makes realloc() honor "zeroise" and "poison_in_malloc" flags.

This test casts 0x4 to a function pointer and calls it. Unfortunately, the faulting address may not exactly be 0x4 on PPC64 ELFv1 systems. The LLVM PPC backend used to always generate the loads "in order", so we'd fault at 0x4 anyway. However, at upcoming change to loosen that ordering, and we'll pick a different order on some targets.
