2016-04-14[sanitizer] [SystemZ] Add/fix kernel and libc type definitions.Marcin Koscielnicki
This is the first part of upcoming asan support for s390 and s390x. Note that there are bits for 31-bit support in this and subsequent patches - while LLVM itself doesn't support it, gcc should be able to make use of it just fine.

2015-10-26[compiler-rt] Enable ptrace sanitizer for armAdhemerval Zanella
This patch enables the ptrace syscall interceptors for arm and adds support for both PTRACE_GETVFPREGS and PTRACE_SETVFPREGS used to get the VFP register from ARM. The ptrace tests is also updated with arm and PTRACE_GETVFPREGS tests. git-svn-id: https://llvm.org/svn/llvm-project/compiler-rt/trunk@251321 91177308-0d34-0410-b5e6-96231b3b80d8
2015-10-12[asan] Zero initialize sem_t in sem_init.Evgeniy Stepanov
Old version of sem_init (GLIBC_2.0) fails to initialize parts of sem_t that are used in sem_timedwait. This is fixed in GLIBC_2.1, but since ASan interceptors downgrade sem_* to the oldest available version, this can introduce bugs that are only present in sanitized build. Workaround by zero-initializing sem_t in sem_init. git-svn-id: https://llvm.org/svn/llvm-project/compiler-rt/trunk@250113 91177308-0d34-0410-b5e6-96231b3b80d8
2015-09-16[MSan] Enable MSAN for aarch64Adhemerval Zanella
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. git-svn-id: https://llvm.org/svn/llvm-project/compiler-rt/trunk@247809 91177308-0d34-0410-b5e6-96231b3b80d8
2015-09-08[msan] Unpoison dlpi_phdr in dl_iterate_phdr.Evgeniy Stepanov

2015-01-21[sanitizer] Fix aarch64 sanitizer build with recent glibcKostya Serebryany
glibc recently changed ABI on aarch64-linux: https://sourceware.org/git/?p=glibc.git;a=commit;h=5c40c3bab2fddaca8cfe12d75944d1fef8adf1a4 Instead of having unsigned short mode; unsigned short __pad1; it now has unsigned int mode; field in ipc_perm structure. This patch allows to build against the recent glibc and disables the ipc_perm.mode verification for older versions of glibc. I think it shouldn't be a big deal even for older glibcs, I couldn't find any place which would actually care about the exact mode field, rather than the whole structure, appart from the CHECK_SIZE_AND_OFFSET macro.
