Alexander Potapenko 4672bacaef [ASan] Get rid of asan_mac.h, which contents have been moved to sanitizer_mac.h

Alexander Potapenko 844a3cf77e [ASan] Use replace_str=0 and replace_intrin=0 in printf-{2,4}.c to avoid triggering a buffer overflow in strlen and memcpy.

Alexander Potapenko 2e7dc60ee3 [ASan] Replace the call to "vname" with "WRAP(vname)" in FORMAT_INTERCEPTOR_IMPL
It's incorrect to call the function by its name in the interceptor, because that means WRAP(vname) on Linux and REAL(vname) on OSX.

This patch fixes asan/lit_tests/TestCases/printf-3.c on Mac.

Dmitry Vyukov 8aaa44c43d tsan: relax check for errno spoiling more
We do not detect errno spoiling for SIGTERM,
because some SIGTERM handlers do spoil errno but reraise SIGTERM,
tsan reports false positive in such case.
It's difficult to properly detect this situation (reraise),
because in async signal processing case (when handler is called directly
from rtl_generic_sighandler) we have not yet received the reraised
signal; and it looks too fragile to intercept all ways to reraise a signal.

Renato Golin 66e2b70e59 Enable compilation of RT on ARM
Adding the ARM RT sources to the CMake files, and enabling some
sanitizers to also build on ARM. This is far from supported or
production quality, but enabling it to build will get us errors
that we can actually fix.

Having said that, the Compiler-RT and the Asan libraries are
know to work on some variations of ARM.

Dmitry Vyukov 16e7a758b0 tsan: do not deadlock on fork
Currently correct programs can deadlock after fork, because atomic operations and async-signal-safe calls are not async-signal-safe under tsan.
With this change:
- if a single-threaded program forks, the child continues running with verification enabled (the tsan background thread is recreated as well)
- if a multi-threaded program forks, then the child runs with verification disabled (memory accesses, atomic operations and interceptors are disabled); it's expected that it will exec soon anyway
- if the child tries to create more threads after multi-threaded fork, the program aborts with error message
- die_after_fork flag is added that allows to continue running, but all bets are off

New/delete implementations in system libraries almost always are built without
frame pointers. As we switched to frame pointer based unwinder on ARM, they no
longer work for us, resulting in broken allocation/deallocation stacks.

Note that this does not work with statically linked
libstdc++/libc++/libstlport.

Tim Northover bea1cafde8 Macho-embedded: update build script for newer Clang behaviour.
Clang now uses the *-apple-macho triples for embedded targets using MachO. The
environment makes less pretences to be running an actual Mach kernel with all
the support that would imply, so a few changes are needed to the build scripts:
    
+ The Apple way of detecting endianness applies in all cases so drop the
  __MACH__ test.
+ A quick rename since "darwin_embedded" no longer makes any sense. If there's
  no Mach going on, there's certainly no Darwin.
+ Change how we test for support for a platform. The functions we build don't
  need any SDK support (stdio.h, ...) so we don't need to check for it.

Kostya Serebryany 714c67c31e [asan] extend asan-coverage (still experimental).
- add a mode for collecting per-block coverage (-asan-coverage=2).
   So far the implementation is naive (all blocks are instrumented),
   the performance overhead on top of asan could be as high as 30%.
 - Make sure the one-time calls to __sanitizer_cov are moved to function buttom,
   which in turn required to copy the original debug info into the call insn.

Here is the performance data on SPEC 2006
(train data, comparing asan with asan-coverage={0,1,2}):

This change adds ASAN_OPTIONS=start_deactivated=1 flag. When present, ASan will

Chandler Carruth a989fb5ce7 Fix an ODR violation in the sanitizer runtimes.
A helper function is a C++ function, and so even though one of the two
definitions is weak, it still technically triggers the ODR. Perhaps
these two definitions are ODR equivalent, but I'm not even confident in
that.

Instead, just define the function once, declare it as weak, and use
a wrapper that is clearly file-local. This avoids two definitions. Also
make the function extern "C" so that we can't even mess up the type
signature somehow or otherwise fail to match up the weak declaration
here with the interceptor defined elsewhere.

Dmitry Vyukov ce3721057d tsan: remove in_rtl counter
This is intended to address the following problem.
Episodically we see CHECK-failures when recursive interceptors call back into user code. Effectively we are not "in_rtl" at this point, but it's very complicated and fragile to properly maintain in_rtl property. Instead get rid of it. It was used mostly for sanity CHECKs, which basically never uncover real problems.
Instead introduce ignore_interceptors flag, which is used in very few narrow places to disable recursive interceptors (e.g. during runtime initialization).

Alexey Samsonov 1c256cbcc4 [Sanitizer] Add rudimentary support for using libbacktrace in symbolizer.
More steps are needed to actually make it usable:
* sanitizer runtimes should be compiled with -DSANITIZER_LIBBACKTRACE.
* libbacktrace headers should be installed.
* user has to manually link in libbacktrace.a into the executable.

We can easily solve the first two problems in the build system, but
detecting/linking libbacktrace to all the tests we have and end-user programs
is more challenging (and will unlikely work w/o Driver support).

Based on the patch by Jakub Jelinek!

Some linux headers are broken on older kernels.
Instead of depending on the constants and types from such headers directly,
we provide our own definitions and then verify them with compile-time

switching to some other way of testing on older kernels, or even disable the
tests as the last resort (after all, kernel interfaces are supposed to be
stable).

Summary:
Definitions we use in public sanitizer headers may

Moreover, we generally forbid to include any system headers (like <stdint.h>)
in sanitizer runtime headers. This leads to inevitable duplication of selected
interface function declarations, but we decided to live with it.

Alexey Samsonov 4d369187ec [Sanitizer] Print symbolized stack frame using a single Printf() call.
This reduces the number of "write" syscalls performed to print a single
stack frame description, and makes sanitizer output less intermixed with
program output. Also, add a number of unit tests.

Alexey Samsonov 9ff4598225 [ASan] Do not rely on malloc context in allocator reports.
Invoke a fatal stack trace unwinder when ASan prints allocator-relevant
error reports (double-free, alloc-dealloc-mismatch, invalid-free).
Thus we'll be able to print complete stack trace even if allocation/free
stacks are not stored (malloc_context_size=0).

Based on the patch by Yuri Gribov!

Alexander Potapenko fa82ba91f9 [ASan] Don't call __asan_init() from certain interceptors on Darwin.
Fixes http://gcc.gnu.org/bugzilla/show_bug.cgi?id=58994, which hadn't
manifested in LLVM because libclang_rt.asan_osx_dynamic.dylib used to depend on
the Foundation framework.
Without that dependency some interceptors may be called from the system
libraries before libSystem_initializer() is called, which lead to assertion
failures in sanitizer_mac.cc (_NSGetEnviron() returns NULL).

To fix the problem we fall back to the original functions in the common
libsanitizer interceptors and the __cxa_atexit() interceptor on Darwin.

This patch also prints a better error message in the case _NSGetEnviron()
returns NULL.

Tim Northover 38a0cb5201 ARM: make assembly files compile Thumb2 with nop IT block.
ARM's UAL syntax allows the same assembly file to be compiled in both ARM and
Thumb mode. Conditional execution is handled by requiring the Thumb IT blocks,
but essentially ignoring them when compiling for ARM.
