2018-07-06[MSan] Add functions to enable/disable interceptor checks.Matt Morehouse
Summary: The motivation for this change is to make libFuzzer+MSan possible without instrumenting libFuzzer. See https://github.com/google/sanitizers/issues/958.

2017-12-21[sanitizer] Make function declarations C-compatiblePetr Hosek
The public sanitizer headers are intended to be usable from either C++ or C, but they declare no-argument functions with the syntax that is not a proper prototype declaration in C. This goes unnoticed until someone uses -Wsystem-headers.

2015-08-21[Sanitizers] Unify the semantics and usage of "exitcode" runtime flag across ↵Alexey Samsonov
all sanitizers. Summary: Merge "exitcode" flag from ASan, LSan, TSan and "exit_code" from MSan into one entity. Additionally, make sure sanitizer_common now uses the value of common_flags()->exitcode when dying on error, so that this flag will automatically work for other sanitizers (UBSan and DFSan) as well. User-visible changes: * "exit_code" MSan runtime flag is now deprecated. If explicitly specified, this flag will take precedence over "exitcode". The users are encouraged to migrate to the new version. * __asan_set_error_exit_code() and __msan_set_exit_code() functions are removed. With few exceptions, we don't support changing runtime flags during program execution - we can't make them thread-safe. The users should use __sanitizer_set_death_callback() that would call _exit() with proper exit code instead. * Plugin tools (LSan and UBSan) now inherit the exit code of the parent tool. In particular, this means that ASan would now crash the program with exit code "1" instead of "23" if it detects leaks.

2014-07-07Generalize sanitizer allocator public interface.Alexey Samsonov
Introduce new public header <sanitizer/allocator_interface.h> and a set of functions __sanitizer_get_ownership(), __sanitizer_malloc_hook() etc. that will eventually replace their tool-specific equivalents (__asan_get_ownership(), __msan_get_ownership() etc.). Tool-specific functions are now deprecated and implemented as stubs redirecting to __sanitizer_ versions (which are implemented differently in each tool). Replace all uses of __xsan_ versions with __sanitizer_ versions in unit and lit tests. git-svn-id: https://llvm.org/svn/llvm-project/compiler-rt/trunk@212469 91177308-0d34-0410-b5e6-96231b3b80d8
2014-05-21[msan] Chained origins re-design.Evgeniy Stepanov
Generalize StackDepot and create a new specialized instance of it to efficiently (i.e. without duplicating stack trace data) store the origin history tree. This reduces memory usage for chained origins roughly by an order of magnitude. Most importantly, this new design allows us to put two limits on stored history data (exposed in MSAN_OPTIONS) that help avoid exponential growth in used memory on certain workloads. See comments in lib/msan/msan_origin.h for more details. git-svn-id: https://llvm.org/svn/llvm-project/compiler-rt/trunk@209284 91177308-0d34-0410-b5e6-96231b3b80d8
