Kostya Serebryany 8cc7b627b4 [asan] asan_allocator2: do less work under the quarantine lock; make the strcasecmp test more resistant to the contents of unaddressable memory

Kostya Serebryany 9479a85963 [asan] fix a build warning
llvm-svn: 171200
2012-12-28 15:55:43 +00:00
Kostya Serebryany cb510e50e2 [asan] implement more strict checking for memset/etc parameters. Instead of checking the first and the last byte, we check the entire shadow region. This costs ~10 slowdown for the instrumented functions. Motivated by a nasty memset-buffer-overflow-by-140-bytes in chrome which was reported as a use-after-free or not at all

Kostya Serebryany 4a0d946a43 [asan] relax asan/lit_tests/malloc_delete_mismatch.cc to make it pass on Mac 10.7 (where extra frames creep in between malloc and main)

Kostya Serebryany 390cf94f88 [asan] asan_allocator2: do not align the requested size to the redzone size (saves a bit more memory)
llvm-svn: 171111
2012-12-26 12:20:35 +00:00
Kostya Serebryany 35cc75876a [asan] asan_allocator2: implement adaptive redzones. Now with asan_allocator2 allocations <= 48 bytes have 16 byte redzone, allocations of 48-96 bytes -- have 32 bytes redzone, etc (max redzone is 2048). If ASAN_OPTIONS=redzone=n is set, it changes the minimal redzone size

2012-12-26 10:41:24 +00:00
Kostya Serebryany a11cd57a78 [asan] asan_allocator2: by default use the StackDepot to store the stack traces instead of storing them in the redzones
llvm-svn: 171099
2012-12-26 06:30:02 +00:00
Kostya Serebryany 27ad15e165 [asan] asan_allocator2: store the user requested size in just 32 bits (larger sizes use metadata). This allows to put one more 32-bit field into the chunk header
llvm-svn: 171089
2012-12-26 04:52:07 +00:00
Kostya Serebryany eff9b4b9b1 [asan] add a test for right OOB with special large sizes. Fix this test in asan_allocator2. More test tweaking for allocator2
llvm-svn: 171058
2012-12-25 09:40:20 +00:00
Kostya Serebryany 181f504d82 [asan] properly define ASAN_LOW_MEMORY. Due to a mistake it has been always true causing redzone and quarantine sizes to be smaller than it was some time before (and out of sync with the documentation). Also make one test less greedy

Alexey Samsonov 53a965e125 [Sanitizer] Don't implicitly add object files to the list of dependencies when building compiler_rt unittests. Fix sanitizer_common and asan build rules accordingly. This also fixes check-sanitizer command on Ninja.

2012-12-21 08:56:14 +00:00
Kostya Serebryany 3674c6b13b [asan] add a flag alloc_dealloc_mismatch (off by default for now) which finds malloc/delete, new/free, new/delete[], etc mismatches

Kostya Serebryany c0d8ca5537 [asan] asan_allocator2: implement memalign
llvm-svn: 170697
2012-12-20 14:35:06 +00:00
Alexander Potapenko 5e9e51874e [ASan] Make the FileCheck pattern more c++filt-resistant.
This test didn't pass for me locally because of "T0's stack" being converted to "T0'short stack" by c++filt.
Strange enough this doesn't show up on our bots.

2012-12-19 13:46:58 +00:00
Alexey Samsonov ca7fcf2354 Significantly change the way we build ASan unittests in CMake
build tree. Now just-built Clang is used to:
  1) compile instrumented sources (as before);
  2) compile non-instrumented sources;
  3) compile our own instrumented version of googletest;
  4) link it all together using -fsanitize=address flag
     (instead of trying to copy linker behavior in
      CMake build rules).

This makes ASan unittests pretty much self-consistent
and independent of other LLVM libraries.
