2018-07-23[libFuzzer] Handle unstable edges by using minimum hit countsMax Moroz
Summary: Created unstable_handle flag that takes 1 or 2, depending on the handling type. Modified RunOne to accommodate the following heuristic: Use the first CollectFeatures to count how many features there are. If no new features, CollectFeatures like before. If there is new feature, we run CB 2 more times, Check which edges are unstable per input and we store the least amount of hit counts for each edge. Apply these hit counts back to inline8bitcounters so that CollectFeatures can work as intended. Modified UnstableCounters to 8int_t and created a bitset UnstableSet to tell which edges are unstable.

2018-07-20Mark REAL(swapcontext) with indirect_return attribute on x86H.J. Lu
When shadow stack from Intel CET is enabled, the first instruction of all indirect branch targets must be a special instruction, ENDBR. lib/asan/asan_interceptors.cc has ... int res = REAL(swapcontext)(oucp, ucp); ... REAL(swapcontext) is a function pointer to swapcontext in libc. Since swapcontext may return via indirect branch on x86 when shadow stack is enabled, as in this case, int res = REAL(swapcontext)(oucp, ucp); ^^^^^^^^^^^^^^^^^^^^^^^^^^^^ This function may be returned via an indirect branch. Here compiler must insert ENDBR after call, like call *bar(%rip) endbr64 I opened an LLVM bug: https://bugs.llvm.org/show_bug.cgi?id=38207 to add the indirect_return attribute so that it can be used to inform compiler to insert ENDBR after REAL(swapcontext) call. We mark REAL(swapcontext) with the indirect_return attribute if it is available.

2018-07-20[scudo] Simplify internal names (NFC)Kostya Kortchinsky
Summary: There is currently too much redundancy in the class/variable/* names in Scudo: - we are in the namespace `__scudo`, so there is no point in having something named `ScudoX` to end up with a final name of `__scudo::ScudoX`; - there are a lot of types/* that have `Allocator` in the name, given that Scudo is an allocator I figure this doubles up as well. So change a bunch of the Scudo names to make them shorter, less redundant, and overall simpler. They should still be pretty self explaining (or at least it looks so to me). The TSD part will be done in another CL (eg `__scudo::ScudoTSD`).

2018-07-18[Fuzzer] Improve crash unwinding on FuchsiaPetr Hosek
Fuchsia doesn't have signals; instead it expects processes to have a dedicated exception thread that binds to the process' exception port and waits for exception packets to be delivered. On the other hand, libFuzzer and sanitizer_common use expect to collect crash information via libunwind from the same thread that caused the exception. The long term fix is to improve support for remote unwinding in libunbwind, plumb this through sanitizer_common and libFuzzer, and handle the exception exclusively on the exception thread. In the meantime, this revision has the exception thread "resurrect" the crashing thread by: * saving its general purpose register state onto the crashing thread's stack, * setting the crashing thread's program counter to an assembly trampoline with the CFI information needed by libunwind, and * resuming the crashed thread.

2018-07-18[XRay][compiler-rt] Segmented Array: Simplify and OptimiseDean Michael Berris
Summary: This is a follow-on to D49217 which simplifies and optimises the implementation of the segmented array. In this patch we co-locate the book-keeping for segments in the `__xray::Array<T>` with the data it's managing. We take the chance in this patch to actually rename `Chunk` to `Segment` to better align with the high-level description of the segmented array. With measurements using benchmarks landed in D48879, we've identified that calls to `pthread_getspecific` started dominating the cycles, which led us to revert the change made in D49217 to use C++ thread_local initialisation instead (it reduces the cost by a huge margin, since we save one PLT-based call to pthread functions in the hot path). In particular, this is in `__xray::getThreadLocalData()`. We also took the opportunity to remove the least-common-multiple based calculation and instead pack as much data into segments of the array. This greatly simplifies the API of the container which hides as much of the implementation details as possible. For instance, we calculate the number of elements we need for the each segment internally in the Array instead of making it part of the type. With the changes here, we're able to get a measurable improvement on the performance of profiling mode on top of what D48879 already provides. Depends on D48879.

2018-07-18[XRay][compiler-rt] Simplify Allocator ImplementationDean Michael Berris
Summary: This change simplifies the XRay Allocator implementation to self-manage an mmap'ed memory segment instead of using the internal allocator implementation in sanitizer_common. We've found through benchmarks and profiling these benchmarks in D48879 that using the internal allocator in sanitizer_common introduces a bottleneck on allocating memory through a central spinlock. This change allows thread-local allocators to eliminate contention on the centralized allocator. To get the most benefit from this approach, we also use a managed allocator for the chunk elements used by the segmented array implementation. This gives us the chance to amortize the cost of allocating memory when creating these internal segmented array data structures. We also took the opportunity to remove the preallocation argument from the allocator API, simplifying the usage of the allocator throughout the profiling implementation. In this change we also tweak some of the flag values to reduce the amount of maximum memory we use/need for each thread, when requesting memory through mmap. Depends on D48956.

2018-07-16[libFuzzer] Implement stat::stability_rate based on the percentage of ↵Max Moroz
unstable edges. Summary: Created a -print_unstable_stats flag. When -print_unstable_stats=1, we run it 2 more times on interesting inputs poisoning unstable edges in an array. On program termination, we run PrintUnstableStats() which will print a line with a stability percentage like AFL does. Patch by Kyungtak Woo (@kevinwkt).

2018-07-16[XRay][compiler-rt] Use `SANITIZER_CXX_ABI_LIBRARY` for XRay unit testsDean Michael Berris
Summary: Fix a TODO in CMake config for XRay tests to use the detected C++ ABI library in the tests. Also make the tests depend on the llvm-xray target when built in-tree.

2018-07-15[CMake] Change the flag to use compiler-rt builtins to booleanPetr Hosek
This changes the name and the type to what it was prior to r333037 which matches the name of the flag used in other runtimes: libc++, libc++abi and libunwind. We don't need the type to be a string since there's only binary choice between libgcc and compiler-rt unlike in the case of C++ library where there're multiple options.
