2016-01-26[cfi] Better handling of wild target address.Evgeniy Stepanov
This change enables diagnostics when the target address for a CFI check is out of bounds of any known library, or even not in the limits of the address space. This happens when casting pointers to uninitialized memory. Ubsan code does not yet handle some of these situations correctly, so it is still possible to see a segmentation fault instead of a proper diagnostic message once in a while. git-svn-id: https://llvm.org/svn/llvm-project/compiler-rt/trunk@258879 91177308-0d34-0410-b5e6-96231b3b80d8

2016-01-25[cfi] Cross-DSO CFI diagnostic mode (compiler-rt part)Evgeniy Stepanov
* add __cfi_slowpath_diag with a 3rd parameter which is a pointer to the diagnostic info for the ubsan handlers. *__cfi_check gets a 3rd parameter as well. * unify vcall/cast/etc and icall diagnostic info format, and merge the handlers to have a single entry point (actually two points due to abort/noabort variants). * tests Note that this comes with a tiny overhead in the non-diag mode: cfi_slowpath must pass 0 as the 3rd argument to cfi_check. git-svn-id: https://llvm.org/svn/llvm-project/compiler-rt/trunk@258744 91177308-0d34-0410-b5e6-96231b3b80d8

2016-01-20[MSan] Clear parameters shadow before invoking malloc/free hooks.Alexey Samsonov

2016-01-16[LSan] Ignore all allocations made inside pthread_create.Alexey Samsonov
Thread stack/TLS may be stored by libpthread for future reuse after thread destruction, and the linked list it's stored in doesn't even hold valid pointers to the objects, the latter are calculated by obscure pointer arithmetic. With this change applied, LSan test suite passes with "use_ld_allocations" flag defaulted to "false". It still requires more testing to check if the default can be switched. git-svn-id: https://llvm.org/svn/llvm-project/compiler-rt/trunk@257975 91177308-0d34-0410-b5e6-96231b3b80d8

2016-01-15[tsan] Store the pointer to ThreadState in TLS slot on Android.Yabin Cui
Summary: 1. Android doesn't support __thread keyword. So allocate ThreadState dynamically and store its pointer in one TLS slot provided by Android. 2. On Android, intercepted functions can be called before ThreadState is initialized. So add test of thr_->is_inited in some places. 3. On Android, intercepted functions can be called after ThreadState is destroyed. So add a fake dead_thread_state to represent all destroyed ThreadStates. And that is also why we don't store the pointer to ThreadState in shadow memory of pthread_self().

2016-01-14[LSan] Add "use_ld_allocations" flag to disable old way of DTLS handling.Alexey Samsonov
This flag allows to disable old way of determining dynamic TLS by filtering out allocations from dynamic linker. This will be eventually superseded by __tls_get_addr interceptor (see r257785), after we: 1) Test it in several supported environments 2) Deal with existing problems (currently we can't find a pointer to DTV which is calloc()-ed in pthread_create). git-svn-id: https://llvm.org/svn/llvm-project/compiler-rt/trunk@257789 91177308-0d34-0410-b5e6-96231b3b80d8
2016-01-14[LSan] Use __tls_get_addr interceptor to keep track of dynamic TLS.Alexey Samsonov
Summary: We have a way to keep track of allocated DTLS segments: let's use it in LSan. Although this code is fragile and relies on glibc implementation details, in some cases it proves to be better than existing way of tracking DTLS in LSan: marking as "reachable" all memory chunks allocated directly by "ld". The plan is to eventually get rid of the latter, once we are sure it's safe to remove.

2016-01-14[tsan] Introduce a "ignore_interceptors_accesses" optionKuba Brecka
On OS X, TSan already passes all unit and lit tests, but for real-world applications (even very simple ones), we currently produce a lot of false positive reports about data races. This makes TSan useless at this point, because the noise dominates real bugs. This introduces a runtime flag, "ignore_interceptors_accesses", off by default, which makes TSan ignore all memory accesses that happen from interceptors. This will significantly lower the coverage and miss a lot of bugs, but it eliminates most of the current false positives on OS X.
