Alexey Samsonov aac36b345a [ASan] intercept swapcontext on Linux only 
llvm-svn: 168509
 2012-11-23 10:14:44 +00:00
Kostya Serebryany 734f1eb5f4 [asan/tsan] do not use __WORDSIZE macro, as it is glibc-private thing. Instead, define our own SANITIZER_WORDSIZE

Alexander Potapenko 1eef2b813c [ASan] Rename ReplaceCFAllocator to MaybeReplaceCFAllocator. 
Replace the allocator only if the replace_cfallocator flag is set (in some cases it wasn't checked)

llvm-svn: 166550
 2012-10-24 09:35:23 +00:00
Alexander Potapenko e3e80d607f Do not call ReplaceCFAllocator() before __CFInitialize(), otherwise crashes are possible on 10.8. 
Fixes http://code.google.com/p/address-sanitizer/issues/detail?id=122

llvm-svn: 166029

Kostya Serebryany ee92877f17 [asan] more refactoring to move StackTrace to sanitizer_common 
llvm-svn: 162752
 2012-08-28 13:25:55 +00:00
Kostya Serebryany 6b0d775229 [asan] some renaming before we move StackTrace into sanitizer_common 
llvm-svn: 162747
 2012-08-28 11:54:30 +00:00
Alexander Potapenko fefc1e989c If the program is linked to a dynamic ASan runtime which is not present in DYLD_INSERT_LIBRARIES 
(which, in turn, is required for our interceptors to take effect), re-exec the program with
DYLD_INSERT_LIBRARIES set.

llvm-svn: 162547
 2012-08-24 09:22:05 +00:00
Alexander Potapenko 2ebe619340 Re-implement the wrappers for libdispatch functions using blocks where appropriate 
(kudos to Anna Zaks for a good example).
This simplifies the code much and lets us not implement internal parts of libdispatch.

All ASan tests from t32 and t64 should pass with the dylib runtime now.

llvm-svn: 162202
 2012-08-20 11:59:26 +00:00
Alexander Potapenko 1233d558dc Minor refactoring: reduce code duplication by introducing a macro for dispatch_sync_f, dispatch_async_f, dispatch_barrier_async_f bodies. 
llvm-svn: 162199
 2012-08-20 09:25:10 +00:00
Alexander Potapenko 20f9fcc285 Move the prototype of __CFInitialize to asan_mac.h so that asan_malloc_mac.cc may use it in the dynamic library mode.

Alexey Samsonov 36d2dff143 [ASan] fix cmake build warning 
llvm-svn: 160957
 2012-07-30 10:18:31 +00:00
Alexander Potapenko 51e6488b31 Intercept CFAllocator for each thread in the program. 
Test that child threads use the ASan allocator, that allocated memory can be passed to another thread and deallocated on it.
This should fix http://code.google.com/p/address-sanitizer/issues/detail?id=81

llvm-svn: 160630
 2012-07-23 14:07:58 +00:00
Alexey Samsonov 34efb8e9b9 [ASan] Use common flags parsing machinery. 
llvm-svn: 159933
 2012-07-09 14:36:04 +00:00
Alexander Potapenko 89f9270366 A portable way to check whether __CFInitialize has been called: compare kCFAllocatorSystemDefault._base._cfisa to 0. 
This should fix http://code.google.com/p/address-sanitizer/issues/detail?id=87 on both Lion and Snow Leopard.

llvm-svn: 159821
 2012-07-06 13:04:12 +00:00
Alexander Potapenko d2ff0b087a Do not check for __CFRuntimeClassTableSize on non-10.6 systems, where this symbol is private. 
This change may cause http://code.google.com/p/address-sanitizer/issues/detail?id=87 to re-appear on Lion.

llvm-svn: 159819
 2012-07-06 11:58:54 +00:00
Alexander Potapenko 25b567dd0d Fix http://code.google.com/p/address-sanitizer/issues/detail?id=87 by making sure we replace the default CFAllocator only after __CFInitialize has been called. 
llvm-svn: 159749

Alexey Samsonov 70386aaffa [ASan] cleanup: trailing semicolons, trailing colons in enums 
llvm-svn: 159338
 2012-06-28 08:27:24 +00:00
Alexander Potapenko f9f2fbacb3 Actually intercept free() to ensure that the deallocations caused by other functions directly calling it are routed to our allocator. 
For the allocations that do not belong to any malloc zone check whether they're padded with a pointer to ASan's CFAllocator. If so, free the original (unpadded) pointer.
This should fix AddressSanitizerMac.NSURLDeallocation and issue 70.
