2017-12-14[scudo] Refactor ScudoChunkKostya Kortchinsky
Summary: The initial implementation used an ASan like Chunk class that was deriving from a Header class. Due to potential races, we ended up working with local copies of the Header and never using the parent class fields. ScudoChunk was never constructed but cast, and we were using `this` as the pointer needed for our computations. This was meh. So we refactored ScudoChunk to be now a series of static functions within the namespace `__scudo::Chunk` that take a "user" pointer as first parameter (former `this`). A compiled binary doesn't really change, but the code is more sensible. Clang tends to inline all those small function (in -O2), but GCC left a few not inlined, so we add the `INLINE` keyword to all. Since we don't have `ScudoChunk` pointers anymore, a few variables were renamed here and there to introduce a clearer distinction between a user pointer (usually `Ptr`) and a backend pointer (`BackendPtr`).

2017-12-14[Sanitizers] Basic sanitizer Solaris support (PR 33274)Kamil Rytarowski
Summary: This is the first mostly working version of the Sanitizer port to 32-bit Solaris/x86. It is currently based on Solaris 11.4 Beta. This part was initially developed inside libsanitizer in the GCC tree and should apply to both. Subsequent parts will address changes to clang, the compiler-rt build system and testsuite. I'm not yet sure what the right patch granularity is: if it's profitable to split the patch up, I'd like to get guidance on how to do so. Most of the changes are probably straightforward with a few exceptions: * The Solaris syscall interface isn't stable, undocumented and can change within an OS release. The stable interface is the libc interface, which I'm using here, if possible using the internal _-prefixed names. * While the patch primarily target 32-bit x86, I've left a few sparc changes in. They cannot currently be used with clang due to a backend limitation, but have worked fine inside the gcc tree. * Some functions (e.g. largefile versions of functions like open64) only exist in 32-bit Solaris, so I've introduced a separate SANITIZER_SOLARIS32 to check for that. The patch (with the subsequent ones to be submitted shortly) was tested on i386-pc-solaris2.11. Only a few failures remain, some of them analyzed, some still TBD: AddressSanitizer-i386-sunos :: TestCases/Posix/concurrent_overflow.cc AddressSanitizer-i386-sunos :: TestCases/init-order-atexit.cc AddressSanitizer-i386-sunos :: TestCases/log-path_test.cc AddressSanitizer-i386-sunos :: TestCases/malloc-no-intercept.c AddressSanitizer-i386-sunos-dynamic :: TestCases/Posix/concurrent_overflow.cc AddressSanitizer-i386-sunos-dynamic :: TestCases/Posix/start-deactivated.cc AddressSanitizer-i386-sunos-dynamic :: TestCases/default_options.cc AddressSanitizer-i386-sunos-dynamic :: TestCases/init-order-atexit.cc AddressSanitizer-i386-sunos-dynamic :: TestCases/log-path_test.cc AddressSanitizer-i386-sunos-dynamic :: TestCases/malloc-no-intercept.c SanitizerCommon-Unit :: ./Sanitizer-i386-Test/MemoryMappingLayout.DumpListOfModules SanitizerCommon-Unit :: ./Sanitizer-i386-Test/SanitizerCommon.PthreadDestructorIterations Maybe this is good enough the get the ball rolling.

2017-12-14[XRay][compiler-rt] Coalesce calls to mprotect to reduce patching overheadDean Michael Berris
Summary: Before this change, XRay would conservatively patch sections of the code one sled at a time. Upon testing/profiling, this turns out to take an inordinate amount of time and cycles. For an instrumented clang binary, the cycles spent both in the patching/unpatching routine constituted 4% of the cycles -- this didn't count the time spent in the kernel while performing the mprotect calls in quick succession. With this change, we're coalescing the number of calls to mprotect from being linear to the number of instrumentation points, to now being a lower constant when patching all the sleds through `__xray_patch()` or `__xray_unpatch()`. In the case of calling `__xray_patch_function()` or `__xray_unpatch_function()` we're now doing an mprotect call once for all the sleds for that function (reduction of at least 2x calls to mprotect).

This is feature is not enabled by default on NetBSD as it's unfinished. - Switch intercepting from UTMP to UTMPX functions.

I changed the workaround for the glibc vDSO issue: `__progname` is initialized after the vDSO and is actually public and of known type, unlike `__vdso_clock_gettime`.

2017-12-11[sanitizer] Introduce a vDSO aware time function, and use it in the ↵Kostya Kortchinsky
allocator [redo] Summary: Redo of D40657, which had the initial discussion. The initial code had to move into a libcdep file, and things had to be shuffled accordingly. `NanoTime` is a time sink when checking whether or not to release memory to the OS. While reducing the amount of calls to said function is in the works, another solution that was found to be beneficial was to use a timing function that can leverage the vDSO. We hit a couple of snags along the way, like the fact that the glibc crashes when clock_gettime is called from a preinit_array, or the fact that `__vdso_clock_gettime` is mangled (for security purposes) and can't be used directly, and also that clock_gettime can be intercepted. The proposed solution takes care of all this as far as I can tell, and significantly improve performances and some Scudo load tests with memory reclaiming enabled. @mcgrathr: please feel free to follow up on https://reviews.llvm.org/D40657#940857 here.

2017-12-08[libFuzzer] Add support for Fuchsia OS.Matt Morehouse
Summary: This patch adds the initial support for Fuchsia. - LIBFUZZER_FUCHSIA is added as an OS type in FuzzerDefs.h - Fuchsia is, by design, not POSIX compliant. However, it does use ELF and supports common POSIX I/O functions. Thus, FuzzerExtFunctions.h and FuzzerIO.h are implemented by extending the header guards in FuzzerExtFunctionsWeak.cpp and FuzzerIOPosix.cpp to include LIBFUZZER_FUCHSIA. - The platform-specific portions of FuzzerUtil.h are implemented by FuzzerUtilFuchsia.cpp, which makes use of exception ports, syscalls, and the launchpad library. - The experimental equivalence server is not currently supported, so FuzzerShmem.h is implemented by stub methods in FuzzerShmemFuchsia.cpp. Any future implementation will likely involve VMOs. Tested with ASAN/SanCov on Fuchsia/x86-64 with the canonical toy fuzzer.

2017-12-08[scudo] Minor code generation improvementKostya Kortchinsky
Summary: It looks like clang was generating somewhat weird assembly with the current code. `FromPrimary`, even though `const`, was replaced every time with the code generated for `size <= SizeClassMap::kMaxSize` instead of using a variable or register, and `FromPrimary` didn't induce `ClassId != 0` for the compiler, so a dead branch was generated for `getActuallyAllocatedSize(Ptr, ClassId)` since it's never called for `ClassId = 0` (Secondary backed allocations) [this one was more wishful thinking on my side than anything else]. I rearranged the code bit so that the generated assembly is less clunky. Also changed 2 whitespace inconsistencies that were bothering me.

In more recent Linux kernels with 47 bit VMAs the layout of virtual memory for powerpc64 changed causing the address sanitizer to not work properly. This patch adds support for 47 bit VMA kernels for powerpc64 and fixes up test cases. https://reviews.llvm.org/D40908 There is an associated patch for trunk.

2017-12-06[libFuzzer] Decrease stack usage in unit testsKostya Serebryany
Summary: With 3 Dictionary objects, each containing space of ~16k DictionaryEntry objects, the MutationDispatcher object is fairly memory heavy. On platforms with a lower default stack size, this can cause panics in FuzzerUnittest as those tests stack-allocate the MutationDispatcher. This may be especially problematic for platforms that do not (yet) have a way to programmatically change their stack size, aside from link-time flags. In general, it seems more prudent to use the heap for an object of this size.
