 2013-01-09 12:03:27 +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 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

Chandler Carruth 1aa4fef601 Relocate the external headers provided by ASan and the common sanitizer 
library.

These headers are intended to be available to user code when built with
AddressSanitizer (or one of the other sanitizer's in the future) to
interface with the runtime library. As such, they form stable external
C interfaces, and the headers shouldn't be located within the
implementation.

I've pulled them out into what seem like fairly obvious locations and
names, but I'm wide open to further bikeshedding of these names and
locations.

I've updated the code and the build system to cope with the new
locations, both CMake and Makefile. Please let me know if this breaks
anyone's build.

The eventual goal is to install these headers along side the Clang
builtin headers when we build the ASan runtime and install it. My
current thinking is to locate them at:

  <prefix>/lib/clang/X.Y/include/sanitizer/common_interface_defs.h
  <prefix>/lib/clang/X.Y/include/sanitizer/asan_interface.h
  <prefix>/lib/clang/X.Y/include/sanitizer/...

But maybe others have different suggestions?

Fixing the style of the #include between these headers at least unblocks
experimentation with installing them as they now should work when
installed in these locations.

Chandler Carruth c1c9d5818f Some flag cleanup for the sanitizer runtimes. 
This hoists most of the CFLAGS into a common variable. It also adds
detection for -Wno-c99-extensions and uses it to silence a pile of
warnings.

Finally, it switches to the proper flag -rdynamic.

With this, the cmake build is warning free on my bootstrap Linux build.

Dmitry Vyukov 7e6347402d tsan: fix new memory allocator 
Deallocate: drain blocks to central cache if cached too much (instead of never drain).
Allocate: batch allocate fixed amount of blocks (instead of all blocks).
This significantly reduces memory consumption of large heavy-multithreaded programs.

Alexey Samsonov 563fb4113c [Sanitizer] Add external symbolizer binary. Next steps - include it in CMake build (produce 32-bit and 64-bit version of it, make sure we can compile LLVM sources with our own flags) and add tests for it.

Alexey Samsonov 419f610a74 [Sanitizer] Switch the symbolization strategy that would be used by sanitizer tools family: as compiling in-process symbolizer into runtime involves certain difficulties, we may instead launch an external symbolizer program (fork + execl) in a subprocess and communicate with it via pipe.

Alexey Samsonov 500e99639d [Sanitizer] Wrapper around llvm::DIContext from LLVM DebugInfo library. If a macro SANITIZER_USES_LLVM_LIBS is defined (by default it is not), then sanitizer runtime includes llvm headers and tries to use LLVM libs for in-process symbolization. To make it functional, we have to link with these LLVM libs - either pass them to linker from Clang driver, or link them into static ASan runtime when we build it.
