* Stop tracking atexit/__cxa_atexit/pthread_atfork allocations in LSan/NetBSDKamil Rytarowski2019-09-211-0/+12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Summary: The atexit(3) and __cxa_atexit() calls allocate internally memory and free on exit, after executing all callback. This causes false positives as DoLeakCheck() is called from the atexit handler. In the LSan/ASan tests there are strict checks triggering false positives here. Intercept all atexit(3) and __cxa_atexit() calls and disable LSan when calling the real functions. Stop tracing allocations in pthread_atfork(3) funtions, as there are performed internal allocations that are not freed for the time of running StopTheWorld() code. This avoids false-positives. The same changes have to be replicated in the ASan and LSan runtime. Non-NetBSD OSs are not tested and this code is restricted to NetBSD only.

* [Sanitizer] Reland "Cleanup INTERCEPT_FUNCTION macro"Julian Lettner2019-05-011-2/+2
| | | | | | | | | | | | | | | | | | | | | | On Linux both version of the INTERCEPT_FUNCTION macro now return true when interception was successful. Adapt and cleanup some usages. Also note that `&(func) == &WRAP(func)` is a link-time property, but we do a runtime check. Tested on Linux and macOS. Previous attempt reverted by: 5642c3feb03d020dc06a62e3dc54f3206a97a391 This attempt to bring order to the interceptor macro goes the other direction and aligns the Linux implementation with the way things are done on Windows.

| | | | | | | | | | | | | | | to void" Changing INTERCEPT_FUNCTION to return void is not functionally correct. IMO the best way to communicate failure or success of interception is with a return value, not some external address comparison.

* [asan] Replace vfork with fork.Evgeniy Stepanov2018-03-161-0/+2
| | | | | | | | | | | | | | | | | | | | Summary: vfork is not ASan-friendly because it modifies stack shadow in the parent process address space. While it is possible to compensate for that with, for example, __asan_handle_no_return before each call to _exit or execve and friends, simply replacing vfork with fork looks like by far the easiest solution. Posix compliant programs can not detect the difference between vfork and fork.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Summary: Fixes Bug 32434 See https://bugs.llvm.org/show_bug.cgi?id=32434 Short summary: std::rethrow_exception does not use __cxa_throw to rethrow the exception, so if it is called from uninstrumented code, it will leave the stack poisoned. This can lead to false positives. Long description: For functions which don't return normally (e.g. via exceptions), asan needs to unpoison the entire stack. It is not known before a call to such a function where execution will continue, some function which don't contain cleanup code like destructors might be skipped. After stack unwinding, execution might continue in uninstrumented code. If the stack has been poisoned before such a function is called, but the stack is unwound during the unconventional return, then zombie redzones (entries) for no longer existing stack variables can remain in the shadow memory. Normally, this is avoided by asan generating a call to asan_handle_no_return before all functions marked as [[noreturn]]. This asan_handle_no_return unpoisons the entire stack. Since these [[noreturn]] functions can be called from uninstrumented code, asan also introduces interceptor functions which call asan_handle_no_return before running the original [[noreturn]] function; for example, cxa_throw is intercepted. If a [[noreturn]] function is called from uninstrumented code (so the stack is left poisoned) and additionally, execution continues in uninstrumented code, new stack variables might be introduced and overlap with the stack variables which have been removed during stack unwinding. Since the redzones are not cleared nor overwritten by uninstrumented code, they remain but now contain invalid data. Now, if the redzones are checked against the new stack variables, false positive reports can occur. This can happen for example by the uninstrumented code calling an intercepted function such as memcpy, or an instrumented function. Intercepting std::rethrow_exception directly is not easily possible since it depends on the C++ standard library implementation (e.g. libcxx vs libstdc++) and the mangled name it produces for this function. As a rather simple workaround, we're intercepting _Unwind_RaiseException for libstdc++. For libcxxabi, we can intercept the ABI function __cxa_rethrow_primary_exception. Patch by Robert Schneider.

* [Sanitizers] Basic sanitizer Solaris support (PR 33274)Kamil Rytarowski2017-12-141-3/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Summary: This is the first mostly working version of the Sanitizer port to 32-bit Solaris/x86. It is currently based on Solaris 11.4 Beta. This part was initially developed inside libsanitizer in the GCC tree and should apply to both. Subsequent parts will address changes to clang, the compiler-rt build system and testsuite. I'm not yet sure what the right patch granularity is: if it's profitable to split the patch up, I'd like to get guidance on how to do so. Most of the changes are probably straightforward with a few exceptions: * The Solaris syscall interface isn't stable, undocumented and can change within an OS release. The stable interface is the libc interface, which I'm using here, if possible using the internal _-prefixed names. * While the patch primarily target 32-bit x86, I've left a few sparc changes in. They cannot currently be used with clang due to a backend limitation, but have worked fine inside the gcc tree. * Some functions (e.g. largefile versions of functions like open64) only exist in 32-bit Solaris, so I've introduced a separate SANITIZER_SOLARIS32 to check for that. The patch (with the subsequent ones to be submitted shortly) was tested on i386-pc-solaris2.11. Only a few failures remain, some of them analyzed, some still TBD: AddressSanitizer-i386-sunos :: TestCases/Posix/concurrent_overflow.cc AddressSanitizer-i386-sunos :: TestCases/init-order-atexit.cc AddressSanitizer-i386-sunos :: TestCases/log-path_test.cc AddressSanitizer-i386-sunos :: TestCases/malloc-no-intercept.c AddressSanitizer-i386-sunos-dynamic :: TestCases/Posix/concurrent_overflow.cc AddressSanitizer-i386-sunos-dynamic :: TestCases/Posix/start-deactivated.cc AddressSanitizer-i386-sunos-dynamic :: TestCases/default_options.cc AddressSanitizer-i386-sunos-dynamic :: TestCases/init-order-atexit.cc AddressSanitizer-i386-sunos-dynamic :: TestCases/log-path_test.cc AddressSanitizer-i386-sunos-dynamic :: TestCases/malloc-no-intercept.c SanitizerCommon-Unit :: ./Sanitizer-i386-Test/MemoryMappingLayout.DumpListOfModules SanitizerCommon-Unit :: ./Sanitizer-i386-Test/SanitizerCommon.PthreadDestructorIterations Maybe this is good enough the get the ball rolling.
