* Add missing decoding patterns toRoundUpToInstrBoundaryEtienne Bergeron2016-06-201-0/+16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Summary: The RoundUpToInstrBoundary determines intructions boundary and it's used to determine how to patch (intercept) functions. The current x64-bit implementation is incomplete. This patch is adding patterns observed when trying to sanitize a 64-bit executable on my computer. Thw two current functions not intercepted are: ``` RaiseExceptionStub: 000000007720C3B0 EB 06 jmp RaiseException (07720C3B8h) 000000007720C3B2 90 nop 000000007720C3B3 90 nop 000000007720C3B4 90 nop 000000007720C3B5 90 nop 000000007720C3B6 90 nop 000000007720C3B7 90 nop RaiseException: 000000007720C3B8 FF 25 3A 18 09 00 jmp qword ptr [__imp_RaiseException (07729DBF8h)] 000000007720C3BE 8B 44 24 54 mov eax,dword ptr [rsp+54h] 000000007720C3C2 85 C0 test eax,eax 000000007720C3C4 0F 84 F5 05 00 00 je Wow64NtCreateKey+12Fh (07720C9BFh) ``` ``` CreateThreadStub: 0000000077215A10 48 83 EC 48 sub rsp,48h 0000000077215A14 48 8B 44 24 78 mov rax,qword ptr [rsp+78h] 0000000077215A19 48 89 44 24 38 mov qword ptr [rsp+38h],rax 0000000077215A1E 8B 44 24 70 mov eax,dword ptr [rsp+70h] ``` Reviewers: rnk Subscribers: wang0109, chrisha Differential Revision: http://reviews.llvm.org/D21519 git-svn-id: https://llvm.org/svn/llvm-project/compiler-rt/trunk@273176 91177308-0d34-0410-b5e6-96231b3b80d8
* This patch attempts to primitive support for Win64 asanEtienne Bergeron2016-06-061-26/+147
| | | | | | | | | | | | | | | | Some known issues are: When "head" include instructions that involve branching, the "cut and paste" approach may break down in a way that function interception still work but calling back the original function does not work. The jmp [rip -8] saves some bytes in the "head" but finding the safe zone of 0xCC is not implemented yet. So it may stomp on preceding codes. The shadow offset is not working yet on Win64. More complexity maybe involved since there are some differences regarding virtual address space between Window 8 and Windows 8.1/10. Patch by: Wang Wei Differential Revision: http://reviews.llvm.org/D20884 git-svn-id: https://llvm.org/svn/llvm-project/compiler-rt/trunk@271915 91177308-0d34-0410-b5e6-96231b3b80d8

Missing features: OverrideFunction for x64 an equiv function for inline asm (atomic_compare_exchange_strong) shadow memory offset needs to be adjusted RoundUpToInstrBoundary for x64 They will be implemented by subsequent patches.

* [asan] Intercept all Heap* related imports from ucrtbase.dllReid Kleckner2016-03-242-8/+86
| | | | | | | | | | | | | | | | | | | | | | ucrtbase.dll appears to be built with some kind of cross-module inlining, because there are calls to imported Heap* routines sprinkled throughout the code. This inlining defeats our attempts to hotpatch malloc, _malloc_base, and related functions. Failing to intercept an allocation or deallocation results in a crash when the program attempts to deallocate or reallocate memory with the wrong allocator. This change patches the IAT of ucrtbase.dll to replace the addresses of the imported Heap* functions with implementations provided by ASan. We don't globally intercept the win32 Heap* functions because they are typically used by system DLLs that run before ASan initializes. Eventually, we may want to intercept them, but for now I think this is the minimal change that will keep ASan stable.

* [windows] Implement GetProcAddress internally to avoid initializing the CRTReid Kleckner2015-08-182-4/+59
| | | | | | | | | | | | | | | | | ASan uses GetProcAddress to get the address of malloc so it can patch it. Newer versions of Windows make GetProcAddress initialize the DLL before returning a function pointer into it. That's perfectly reasonable, but ASan needs to finish patching malloc before CRT initialization. So now we roll our own GetProcAddress.

No direct link to 2.8.8 doc): http://www.cmake.org/cmake/help/v3.0/module/CMakeParseArguments.html?highlight=cmake_parse_arguments Since I was already changing these calls, I changed ARCH and LIB into ARCHS and LIBS to make it more clear that they're lists of arguments.

* [ASan] Add CMake configs for libclang_rt.asan_iossim_dynamic.dylib Alexander Potapenko2013-11-071-4/+6
| | | | | | | | | | | CMake changes to build the ASan runtime for the iOS simulator. This is a universal library targeting the same architectures as the OSX ASan runtime does, thus the iossim version can't live in the same universal libclang_rt.asan_osx_dynamic.dylib The difference between the OSX and iossim builds is in the -mios-simulator-version-min and -ios_simulator_version_min flags that tell Clang to compile and link iossim code. The iossim runtime can only be built on a machine with both Xcode and the iOS Simulator SDK installed. If xcodebuild -version -sdk iphonesimulator Path returns a nonempty path, it is used when compiling and linking the iossim runtime. git-svn-id: https://llvm.org/svn/llvm-project/compiler-rt/trunk@194199 91177308-0d34-0410-b5e6-96231b3b80d8
