* Adding Msan support to FreeBSDKamil Rytarowski2018-03-031-0/+2
| | | | | | | | | | | | | | | | | | | | Summary: Enabling the memory sanitizer support for FreeBSD, most of unit tests are compatible. - Adding fstat and stressor_r interceptors. - Updating the struct link_map access since most likely the struct Obj_Entry had been updated since. - Disabling few unit tests until further work is needed (or we can assume it can work in real world code).

* [compiler-rt] [msan] Unify aarch64 mappingAdhemerval Zanella2015-10-291-15/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch unify the 39-bit and 42-bit mapping for aarch64 to use only one instrumentation algorithm. A runtime check avoid mapping 42-bit only segments for 39-bit kernels.

* New MSan mapping layout (compiler-rt part).Evgeniy Stepanov2015-10-081-1/+1
| | | | | | | | | | | | | | | | | | This is an implementation of https://github.com/google/sanitizers/issues/579 It has a number of advantages over the current mapping: * Works for non-PIE executables. * Does not require ASLR; as a consequence, debugging MSan programs in gdb no longer requires "set disable-randomization off". * Supports linux kernels >=4.1.2. * The code is marginally faster and smaller. This is an ABI break. We never really promised ABI stability, but this patch includes a courtesy escape hatch: a compile-time macro that reverts back to the old mapping layout. llvm-svn: 249754
* [MSan] Enable MSAN for aarch64Adhemerval Zanella2015-09-161-0/+18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch enabled msan for aarch64 with 39-bit VMA and 42-bit VMA. As defined by lib/msan/msan.h the memory layout used is for 39-bit is: 00 0000 0000 - 40 0000 0000: invalid 40 0000 0000 - 43 0000 0000: shadow 43 0000 0000 - 46 0000 0000: origin 46 0000 0000 - 55 0000 0000: invalid 55 0000 0000 - 56 0000 0000: app (low) 56 0000 0000 - 70 0000 0000: invalid 70 0000 0000 - 80 0000 0000: app (high) And for 42-bit VMA: 000 0000 0000 - 100 0000 0000: invalid 100 0000 0000 - 11b 0000 0000: shadow 11b 0000 0000 - 120 0000 0000: invalid 120 0000 0000 - 13b 0000 0000: origin 13b 0000 0000 - 2aa 0000 0000: invalid 2aa 0000 0000 - 2ab 0000 0000: app (low) 2ab 0000 0000 - 3f0 0000 0000: invalid 3f0 0000 0000 - 400 0000 0000: app (high) Most of tests are passing with exception of: * Linux/mallinfo.cc * chained_origin_limits.cc * dlerror.cc * param_tls_limit.cc * signal_stress_test.cc * nonnull-arg.cpp The 'Linux/mallinfo.cc' is due the fact AArch64 returns the sret in 'x8' instead of default first argument 'x1'. So a function prototype that aims to mimic (by using first argument as the return of function) won't work. For GCC one can make a register alias (register var asm ("r8")), but for clang it detects is an unused variable and generate wrong code. The 'chained_origin_limits' is probably due a wrong code generation, since it fails only when origin memory is used (-fsanitize-memory-track-origins=2) and only in the returned code (return buf[50]). The 'signal_streess_test' and 'nonnull-arg' are due currently missing variadic argument handling in memory sanitizer code instrumentation on LLVM side. Both 'dlerror' and 'param_tls_test' are unknown failures that require further investigation. All the failures are XFAIL for aarch64 for now. llvm-svn: 247809
