2017-12-07[PowerPC][asan] Update asan to handle changed memory layouts in newer kernelsBill Seurer
In more recent Linux kernels with 47 bit VMAs the layout of virtual memory for powerpc64 changed causing the address sanitizer to not work properly. This patch adds support for 47 bit VMA kernels for powerpc64 and fixes up test cases. https://reviews.llvm.org/D40908 There is an associated patch for trunk. Tested on several 4.x and 3.x kernel releases. git-svn-id: https://llvm.org/svn/llvm-project/compiler-rt/trunk@320110 91177308-0d34-0410-b5e6-96231b3b80d8

2017-12-04[ASan] Enhance libsanitizer support for invalid-pointer-pair.Alex Shlyapnikov
Following patch adds support of all memory origins in CheckForInvalidPointerPair function. For small difference of pointers, it's directly done in shadow memory (the limit was set to 2048B). Then we search for origin of first pointer and verify that the second one has the same origin. If so, we verify that it points either to a same variable (in case of stack memory or a global variable), or to a same heap segment. Committing on behanf of marxin and jakubjelinek.

2017-12-01[ubsan] Re-commit: lit changes for lld testing, future lto testing.Roman Lebedev
Summary: As discussed in https://github.com/google/oss-fuzz/issues/933, it would be really awesome to be able to use ThinLTO for fuzzing. However, as @kcc has pointed out, it is currently undefined (untested) whether the sanitizers actually function properly with LLD and/or LTO. This patch is inspired by the cfi test, which already do test with LTO (and/or LLD), since LTO is required for CFI to function. I started with UBSan, because it's cmakelists / lit.* files appeared to be the cleanest. This patch adds the infrastructure to easily add LLD and/or LTO sub-variants of the existing lit test configurations. Also, this patch adds the LLD flavor, that explicitly does use LLD to link. The check-ubsan does pass on my machine. And to minimize the [initial] potential buildbot breakage i have put some restrictions on this flavour. Please review carefully, i have not worked with lit/sanitizer tests before. The original attempt, r319525 was reverted in r319526 due to the failures in compiler-rt standalone builds.

2017-11-29[sanitizer] Add 'strip_env' flag to enable/disable removing sanitizer dylib ↵Kuba Mracek
from DYLD_INSERT_LIBRARIES On macOS, we usually don't require launching the target with DYLD_INSERT_LIBRARIES anymore. However, it is still necessary when running a target that is not instrumented (and e.g. dlopen's an instrument library later). In any case, ASan and TSan currently remove themselves from the DYLD_INSERT_LIBRARIES environment variable to avoid passing it onto children. This works well e.g. when instrumenting a shell. A problem arises when the target is a non-instrumented shim (e.g. "xcrun") that either re-execs or launches a child that is supposed to get DYLD_INSERT_LIBRARIES propagated. To support this mode, this patch introduces 'strip_env' flag that can be used to keep DYLD_INSERT_LIBRARIES untouched.

2017-11-29[asan] Don't crash on fclose(NULL)Kuba Mracek

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.

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.
