Chandler Carruth 2946cd7010 Update the file headers across all of the LLVM projects in the monorepo
to reflect the new license.

We understand that people may be surprised that we're moving the header
entirely to discuss the new license. We checked this carefully with the
Foundation's lawyer and we believe this is the correct approach.

Essentially, all code in the project is now made available by the LLVM
project under our new license, so you will see that the license headers
include that license only. Some of our contributors have contributed
code under our old license, and accordingly, we have retained a copy of
our old license notice in the top-level files in each project and
repository.

Michal Gorny 5b2b63e524 [sanitizer_common] Remove support for tirpc/rpc/xdr.h
Remove the partial support for rpc/xdr.h from libtirpc.  Since it is
an entirely external library, we ought to build it sanitized separately
and not attempt to intercept like the libc implementation.  Besides,
the existing code for tirpc support was neither complete nor working.

Summary:
The pthread_once(3)/NetBSD type is built with the following structure:

struct __pthread_once_st {
 pthread_mutex_t pto_mutex;
 int pto_done;
};

Set the pto_done position as shifted by __sanitizer::pthread_mutex_t_sz
from the beginning of the pthread_once struct.

This corrects deadlocks when the pthread_once(3) function
is used.

Anna Zaks 691644f3ca [compiler-rt] Do not introduce __sanitizer namespace globally
The definitions in sanitizer_common may conflict with definitions from system headers because:

The runtime includes the system headers after the project headers (as per LLVM coding guidelines).
lib/sanitizer_common/sanitizer_internal_defs.h pollutes the namespace of everything defined after it, which is all/most of the sanitizer .h and .cc files and the included system headers with: using namespace __sanitizer; // NOLINT
This patch solves the problem by introducing the namespace only within the sanitizer namespaces as proposed by Dmitry.

Adhemerval Zanella 19074450ee [MSan] Enable MSAN for aarch64
This patch enabled msan for aarch64 with 39-bit VMA and 42-bit VMA.
As defined by lib/msan/msan.h the memory layout used is for 39-bit is:

   00 0000 0000 - 40 0000 0000:  invalid
   40 0000 0000 - 43 0000 0000:  shadow
   43 0000 0000 - 46 0000 0000:  origin
   46 0000 0000 - 55 0000 0000:  invalid
   55 0000 0000 - 56 0000 0000:  app (low)
   56 0000 0000 - 70 0000 0000:  invalid
   70 0000 0000 - 80 0000 0000:  app (high)

And for 42-bit VMA:

   000 0000 0000 - 100 0000 0000:  invalid
   100 0000 0000 - 11b 0000 0000:  shadow
   11b 0000 0000 - 120 0000 0000:  invalid
   120 0000 0000 - 13b 0000 0000:  origin
   13b 0000 0000 - 2aa 0000 0000:  invalid
   2aa 0000 0000 - 2ab 0000 0000:  app (low)
   2ab 0000 0000 - 3f0 0000 0000:  invalid
   3f0 0000 0000 - 400 0000 0000:  app (high)

Most of tests are passing with exception of:

   * Linux/mallinfo.cc
   * chained_origin_limits.cc
   * dlerror.cc
   * param_tls_limit.cc
   * signal_stress_test.cc
   * nonnull-arg.cpp

The 'Linux/mallinfo.cc' is due the fact AArch64 returns the sret in 'x8'
instead of default first argument 'x1'.  So a function prototype that
aims  to mimic (by using first argument as the return of function) won't
work. For GCC one can make a register alias (register var asm ("r8")), but
for clang it detects is an unused variable and generate wrong code.

The 'chained_origin_limits' is probably due a wrong code generation,
since it fails only when origin memory is used
(-fsanitize-memory-track-origins=2) and only in the returned code
(return buf[50]).

The 'signal_streess_test' and 'nonnull-arg' are due currently missing variadic
argument handling in memory sanitizer code instrumentation on LLVM side.

Both 'dlerror' and 'param_tls_test' are unknown failures that require
further investigation.

All the failures are XFAIL for aarch64 for now.

Instead of having unsigned short mode; unsigned short __pad1; it now has
unsigned int mode; field in ipc_perm structure.

This patch allows to build against the recent glibc and disables the
ipc_perm.mode verification for older versions of glibc.

I think it shouldn't be a big deal even for older glibcs, I couldn't find
any place which would actually care about the exact mode field, rather than
the whole structure, appart from the CHECK_SIZE_AND_OFFSET macro.
