2017-11-17Enable PDB generation with lld in asan and cfi tests on Windows.Peter Collingbourne
PDB emission now works well enough that we can rely on it for these tests to pass. Differential Revision: https://reviews.llvm.org/D40188 git-svn-id: https://llvm.org/svn/llvm-project/compiler-rt/trunk@318546 91177308-0d34-0410-b5e6-96231b3b80d8
2017-11-16[asan] Properly mark or disable tests that only work with shadow scale of 3Walter Lee

2017-11-16[asan] Port tests to shadow scale of 5Walter Lee
The tests are ported as follows: contiguous_container_crash.cc use-after-delete.cc use-after-free.cc Replace hardwired shadow granularity in CHECK statements with regex. max_redzone.cc Bump max_redzone parameter to 32. memset_test.cc Bump size parameter of __asan_poison_memory_region to 32. scariness_score_test.cc For "far-from-bounds" heap overflow, make sure overflow is more than one shadow granularity away. At large shadow granularity, there is not enough redzone between stack elements to detect far-from-bounds, so fake out that test.

2017-10-25[Sanitizers] ASan: detect new/delete calls with mismatched alignment.Alex Shlyapnikov
ASan allocator stores the requested alignment for new and new[] calls and on delete and delete[] verifies that alignments do match. The representable alignments are: default alignment, 8, 16, 32, 64, 128, 256 and 512 bytes. Alignments > 512 are stored as 512, hence two different alignments > 512 will pass the check (possibly masking the bug), but limited memory requirements deemed to be a resonable tradeoff for relaxed conditions. The feature is controlled by new_delete_type_mismatch flag, the same one protecting new/delete matching size check.

2017-10-23[Sanitizers] New sanitizer API to purge allocator quarantine.Alex Shlyapnikov
Summary: Purging allocator quarantine and returning memory to OS might be desired between fuzzer iterations since, most likely, the quarantine is not going to catch bugs in the code under fuzz, but reducing RSS might significantly prolong the fuzzing session.

2017-09-27ASan allocates a global data initialization array at the tail end of eachDmitry Mikulin
compunit's .data section. This vector is not poisoned. Because of this the first symbol of the following section has no left red zone. As a result, ASan cannot detect underflow for such symbols. Poison ASan allocated metadata, it should not be accessible to user code. This fix does not eliminate the problem with missing left red zones but it reduces the set of vulnerable symbols from first symbols in each input data section to first symbols in the output section of the binary.

2017-08-28Reland r311842 - [cmake] Remove i686 target that is duplicate to i386Michal Gorny
Remove the explicit i686 target that is completely duplicate to the i386 target, with the latter being used more commonly. 1. The runtime built for i686 will be identical to the one built for i386. 2. Supporting both -i386 and -i686 suffixes causes unnecessary confusion on the clang end which has to expect either of them. 3. The checks are based on wrong assumption that __i686__ is defined for all newer x86 CPUs. In fact, it is only declared when -march=i686 is explicitly used. It is not available when a more specific (or newer) -march is used. Curious enough, if CFLAGS contain -march=i686, the runtime will be built both for i386 and i686.
