Kostya Serebryany 1cc54f0218 [asan] one more change missed at r171198 
llvm-svn: 171199
 2012-12-28 15:28:19 +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 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

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

 2012-12-25 09:20:58 +00:00
Kostya Serebryany ad24c58e16 [sanitizer] increase the maximum size class of the fast allocator. This should save quite a bit of memory in tsan/msan (and later in asan). This also puts more stress on the large allocator. Add a couple of checks

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
