This test expects pthread_mutex_init in the frame #0 of thread T1 but we
get memset at frame #0 because memset that is called from pthread_init_mutex
is being intercepted by TSan
llvm-svn: 261986
Summary: Msan was intercepting version 2.1 of the pthread_create function which was making it to crash in libc because __pthread_create_2_1 modifies the stack attributes of the thread. Intercepting the correct version fixes the test SmallPreAllocatedStackThread.

Compiler-rt miscalculates the number of entries in the __llvm_prf_data section
on i386 Darwin. This results in a number of test failures (which we started
catching after r261344).
The fix we attempted earlier is insufficient (r261683). It caused some tests to
start passing again, but that hid the fact that we drop some data entries.
This patch should fix the real problem. It fixes the way we compute DataSize by
taking into account the way the Darwin linker lays out __llvm_prf_data.

Fix a crash when gathering value profile data on i386 Darwin.
The Darwin linker shrinks sections containing aligned structures when
padding is not explicitly added to the end of the structure. When
iterating over these structures, be sure to not walk past the end of the

No tests added, since running `ninja check-profile` on i386 Darwin is

The first issue is that we longjmp from ScopedInterceptor scope
when called from an ignored lib. This leaves thr->in_ignored_lib set.
This, in turn, disables handling of sigaction. This, in turn,
corrupts tsan state since signals delivered asynchronously.
Another issue is that we can ignore synchronization in asignal
handler, if the signal is delivered into an IgnoreSync region.
Since signals are generally asynchronous, they should ignore
memory access/synchronization/interceptor ignores.
This could lead to false positives in signal handlers.

I ran the test suite yesterday and when I came back this morning the
queue_user_work_item.cc test was hung. This could be why the
sanitizer-windows buildbot keeps randomly timing out. I updated all the
usages of WaitForSingleObject involving threading events. I'm assuming
the API can reliably wait for subprocesses, which is what the majority

While I'm at it, we can simplify some EH tests now that clang can

We were erroneously reporting 16K as the page size on Windows because

Summary:
In some cases stack pointer register (SP) doesn't point into the thread
stack: e.g. if one is using swapcontext(). In this case LSan
conservatively tries to scan the whole thread stack for pointers.
However, thread stack (at least in glibc implementation) may also
include guard pages, causing LSan to crash when it's reading from them.
One of the solutions is to use a pthread_attr_getguardsize() to adjust
the calculated stack boundaries. However, here we're just using
IsAccessibleMemoryRange to skip guard pages and make the code (slightly)
less platform-specific.

llvm-svn: 257110
Summary:
In rL255491, the safestack overflow test was disabled for aarch64, since
it "is currently failing on an AArch64 buildbot with a segfault, but it
is currently passing on other configuration".
While testing on FreeBSD on x86, I also encountered a segfault. This is
because the `fct()` function actually writes before and after `buffer`,
and on FreeBSD this crashes because `buffer` is usually allocated at the
end of a page. That this runs correctly on Linux is probably just by
accident.
I propose to fix this by adding a pre and post buffer, to act as a
safety zone. The pre and post buffers must be accessed in an 'unsafe'
way, otherwise -fsanitize=safestack will allocate them on the safe
stack, and they will not bookend `buffer` itself. Therefore, I create
them large enough for `fct()`, and call it on both of them.
On FreeBSD, this makes the test run as expected, without segfaulting,
and I suppose this will also fix the segfault on AArch64. I do not have
AArch64 testing capabilities, so if someone could try that out, I would
be much obliged.
