Alexey Samsonov 434984ef58 [UBSan] Make sure proper error summary is printed for -fsanitize=float-cast-overflow.
float-cast-overflow handler doesn't have source location provided by the
compiler, but we still have *some* source location if we have a
symbolizer.

Daniel Sanders 7ea4cfcf83 [ubsan] Stop cast-overflow.cpp test leaking undefined behaviour into the exit code.
Summary:
ubsan was correctly catching the undefined behaviour but lit's shell was
failing the test anyway because the exit code was non-zero as a result of the
undefined behaviour.

This fixes the test on a mips-linux-gnu target.

Daniel Sanders ffa272ebbb [mips] Support building compiler-rt with gcc.
Summary:
This will allow us to enable it on the buildbot (and then enable a
sanitizer buildbot).

The problem is that gcc for Mips does not accept -m32/-m64 like clang does.
We therefore need to use the nearest equivalent -mips32r2/-mips64r2. We must
also specify -mabi=64 in the -mips64r2 case since gcc's default ABI has
traditionally been N32 whereas clang's is N64.

Summary:
When running the compiler-rt testsuite on FreeBSD (it didn't matter which version), I always got the same error result:

After some investigation, it turns out to be due to the regex used for search test_ symbols in lib/dfsan/scripts/check_customer_wrappers.sh:

    grep -E "^\\s*test_.*\(\);" ${DFSAN_CUSTOM_TESTS}

This uses \s to search for whitespace at start of line, but support for \s was only introduced in GNU grep v2.5.4-112-gf979ca0, while both FreeBSD and OSX only have grep 2.5.1 (the last version released under GPLv2).

I propose to change \s into [[:space:]], which is the more portable notation.

Test Plan: Run regression tests, and see that they work now. :)

Sergey Dmitrouk f3206d6278 Add hard float versions of FP to LL conversions
This adds hard-float implementation for the following builtins:

* __fixdfdi()
* __fixsfdi()
* __fixunsdfdi()
* __fixunssfdi()

The soft-float implementation does never raise floating point
exceptions, which doesn't allow clients to detect floating point
conversion errors.

I must mention that I had to refer to libgcc's implementation to
write these functions.

Related unit-tests of compiler-rt passed with these changes.

Patch was somewhat out-dated, so was updated locally without any

This avoids crashing or corrupting data if multiple concurrent

the previous behaviour was a data race that often worked out, and it
ignores errors in flock to fall back to the old racy behaviour so that
it won't degrade the behaviour on filesystems that don't support
flock.

2015-04-01 23:00:02 +00:00
Alexey Samsonov 09dce3b7e5 [UBSan] Embed UBSan into ASan runtime (compiler-rt part).
Summary:
Change the way we use ASan and UBSan together. Instead of keeping two
separate runtimes (libclang_rt.asan and libclang_rt.ubsan), embed UBSan
into ASan and get rid of libclang_rt.ubsan. If UBSan is not supported on
a platform, all UBSan sources are just compiled into dummy empty object
files. UBSan initialization code (e.g. flag parsing) is directly called
from ASan initialization, so we are able to enforce correct
initialization order.

This mirrors the approach we already use for ASan+LSan. This change
doesn't modify the way we use standalone UBSan.

Alexander Potapenko 2dee295a89 [ASan] Suppress the deprecation warning from atos that breaks AtosSymbolizer on OSX 10.9
On OS X 10.9 /usr/bin/atos prints the following warning upon invocation:

 --
Warning: /usr/bin/atos is moving and will be removed from a future OS X release.
It is now available in the Xcode developer tools to be invoked via: `xcrun atos`
To silence this warning, pass the '-d' command-line flag to this tool.
 --

AtosSymbolizer treats the warning as the symbolization result for the first PC passed to the symbolizer. As a result, for each of the following PCs the file:line info for the previous PC is printed, e.g.:

==97926==ERROR: AddressSanitizer: attempting double-free on 0x60200000dfb0 in thread T0:
==97926==Using atos at user-specified path: /usr/bin/atos
==97926==Using dladdr symbolizer.
   #0 0x1007407e0 in  --  (+0x427e0)
   #1 0x1006f6f25 in wrap_free asan_malloc_mac.cc:114
   #2 0x7fff916e05fc in main atos-symbolizer.cc:17
   #3 0x0  (<unknown module>)

Unfortunately atos doesn't accept the -d switch on OSX versions other than 10.9, thus we have to check for the OSX version.

* By default, use LLVMSymbolizer -> DlAddrSymbolizer.
* If the llvm-symbolizer binary is not found, use AtosSymbolizer 
    -> DlAddrSymbolizer.
* If the user specifies ASAN_SYMBOLIZER_PATH=.../atos, then use AtosSymbolizer
    -> DlAddrSymbolizer.
* If neither llvm-symbolizer or atos is found, or external symbolication is
    disabled with ASAN_SYMBOLIZER_PATH="", use DlAddrSymbolizer.

Dmitry Vyukov 6bd917a31f asan: optimization experiments
The experiments can be used to evaluate potential optimizations that remove
instrumentation (assess false negatives). Instead of completely removing
some instrumentation, you set Exp to a non-zero value (mask of optimization
experiments that want to remove instrumentation of this instruction).
If Exp is non-zero, this pass will emit special calls into runtime
(e.g. __asan_report_exp_load1 instead of __asan_report_load1). These calls
make runtime terminate the program in a special way (with a different
exit status). Then you run the new compiler on a buggy corpus, collect
the special terminations (ideally, you don't see them at all -- no false
negatives) and make the decision on the optimization.

The exact reaction to experiments in runtime is not implemented in this patch.
It will be defined and implemented in a subsequent patch.

- SIGSEGV during leak checking
- StopTheWorld operation during signal storm from an external process

Kostya Serebryany be5e0ed919 [sanitizer/coverage] Add AFL-style coverage counters (search heuristic for fuzzing).
Introduce -mllvm -sanitizer-coverage-8bit-counters=1
which adds imprecise thread-unfriendly 8-bit coverage counters.

The run-time library maps these 8-bit counters to 8-bit bitsets in the same way
AFL (http://lcamtuf.coredump.cx/afl/technical_details.txt) does:
counter values are divided into 8 ranges and based on the counter
value one of the bits in the bitset is set.
The AFL ranges are used here: 1, 2, 3, 4-7, 8-15, 16-31, 32-127, 128+.

These counters provide a search heuristic for single-threaded
coverage-guided fuzzers, we do not expect them to be useful for other purposes.

Depending on the value of -fsanitize-coverage=[123] flag,
these counters will be added to the function entry blocks (=1),
every basic block (=2), or every edge (=3).

Use these counters as an optional search heuristic in the Fuzzer library.
Add a test where this heuristic is critical.

The problem is that without SA_RESTORER flag, kernel ignores the handler. So tracer actually did not setup any handler.
Add SA_RESTORER flag when setting up handlers.
Add a test that causes SIGSEGV in stoptheworld callback.
Move SignalContext from asan to sanitizer_common to print better diagnostics about signal in the tracer thread.
