2017-09-18[scudo] Android build supportKostya Kortchinsky
Summary: Mark Android as supported in the cmake configuration for Scudo. Scudo is not added yet in the Android build bots, but code builds and tests pass locally. It is for a later CL. I also checked that Scudo builds as part of the Android toolchain. A few modifications had to be made: - Android defaults to `abort_on_error=1`, which doesn't work well with the current tests. So change the default way to pass `SCUDO_OPTIONS` to the tests to account for this, setting it to 0 by default; - Disable the `valloc.cpp` & `random_shuffle.cpp` tests on Android; - There is a bit of gymnatic to be done with the `SCUDO_TEST_TARGET_ARCH` string, due to android using the `-android` suffix, and `i686` instead of `i386`; - Android doesn't need `-lrt`.

2017-08-30Add preliminary NetBSD support in libfuzzerKamil Rytarowski
Summary: This code already works and passes some number of tests. There is need to finish remaining sanitizers to get better coverage. Many tests fail due to overly long file names of executables (>31). This is a current shortcoming of the NetBSD 8(beta) kernel, as certain functions can fail (like retrieving file name of executable).

2017-08-29Minimal runtime for UBSan.Evgeniy Stepanov
Summary: An implementation of ubsan runtime library suitable for use in production. Minimal attack surface. * No stack traces. * Definitely no C++ demangling. * No UBSAN_OPTIONS=log_file=/path (very suid-unfriendly). And no UBSAN_OPTIONS in general. * as simple as possible Minimal CPU and RAM overhead. * Source locations unnecessary in the presence of (split) debug info. * Values and types (as in A+B overflows T) can be reconstructed from register/stack dumps, once you know what type of error you are looking at. * above two items save 3% binary size. When UBSan is used with -ftrap-function=abort, sometimes it is hard to reason about failures. This library replaces abort with a slightly more informative message without much extra overhead. Since ubsan interface in not stable, this code must reside in compiler-rt.

2017-08-28Reland r311842 - [cmake] Remove i686 target that is duplicate to i386Michal Gorny
Remove the explicit i686 target that is completely duplicate to the i386 target, with the latter being used more commonly. 1. The runtime built for i686 will be identical to the one built for i386. 2. Supporting both -i386 and -i686 suffixes causes unnecessary confusion on the clang end which has to expect either of them. 3. The checks are based on wrong assumption that __i686__ is defined for all newer x86 CPUs. In fact, it is only declared when -march=i686 is explicitly used. It is not available when a more specific (or newer) -march is used. Curious enough, if CFLAGS contain -march=i686, the runtime will be built both for i386 and i686. For any other value, only i386 variant will be built.

Summary: Adding ARM64 as a supported architecture for Scudo. The random shuffle is not yet supported for SizeClassAllocator32, which is used by the AArch64 allocator, so disable the associated test for now.

2017-01-23[lsan] Enable LSan for x86 Linux.Maxim Ostapenko
People keep asking LSan to be available on 32 bit targets (e.g. https://github.com/google/sanitizers/issues/403) despite the fact that false negative ratio might be huge (up to 85%). This happens for big real world applications that may contain random binary data (e.g. browser), but for smaller apps situation is not so terrible and LSan still might be useful. This patch adds initial support for x86 Linux (disabled by default), ARM32 is in TODO list. We used this patch (well, ported to GCC) on our 32 bit mobile emulators and it worked pretty fine thus I'm posting it here to initiate further discussion.
