The iOS crashpad client was mistakenly setting the process annotations
(typically things like version and product name) when converting the
intermediate dump into a minidump. This is incorrect, as those
annotations are determined at intermediate dump creation time.
Instead, correctly write those annotations during intermediate dump
creation. Passing extra annotations during intermediate dump to
minidump is still supported.

This change was partially scripted and partially done manually with vim
regex + manually placing the deleted constructors.
The script change looked for destructors in the public: section of a
class, if that existed the deleted constructors would go before the
destructor.
For manual placement I looked for any constructor in the public: section
of the corresponding class. If there wasn't one, then it would ideally
have gone as the first entry except below enums, classes and typedefs.
This may not have been perfect, but is hopefully good enough. Fingers
crossed.

This will accommodate moving third_party/mini_chromium around.
The default location is unchanged for now.
There are GN variables that may need to be updated when Fuchsia's source
re-organizes its layout:
* mini_chromium_source_parent : this contains a BUILD.gn with groups and
encloses the mini_chromium_source_root. This is controlled by the
structure of the project that depends on this project.
* _mini_chromium_source_root : this is what is normally checked out from
git, the upstream source directory
* mini_chromium_import_root : points inside source_root to make GN files
accessible.
This first step breaks out case logic for "if (crashpad_is_in_fuchsia)"
even if the value is unchanged for now. This will faciliate a smaller
change when Fuchsia re-structures third_party sources.

The load bias is documented to be the difference between
the preferred and actual load address for a module, but
is declared as an unsigned number, and math using it relies
on it being a pointer-precisioned two's complement number
that might cause over- or under-flow.
ElfImageReader and DebugRendezvous both provide ways to get
the load bias for a module and are corroborated in tests.
However, the load bias computed by DebugRendezvous does
not have access to the preferred address, so there is not
enough information to determine the signedness to use with
a VMOffset.
This patch compares the load biases modulo the numeric range
for a pointer to ignore the signedness of the value.
Also update the test module to trigger a negative load bias.

The macOS 11.0 SDK, as of Xcode 12b6 12A8189n, has not updated
<AvailabilityMacros.h> with a MAC_OS_X_VERSION_11_0 or
MAC_OS_X_VERSION_10_16 constant. However, the <Availability.h> interface
has been updated to provide both __MAC_11_0 and __MAC_10_16.
<AvailabilityMacros.h>’s MAC_OS_X_VERSION_MAX_ALLOWED, which is supposed
to identify the SDK version, is broken in the 11.0 SDK in that whenever
the deployment target is set to 10.15 or earlier, the SDK will be
mis-identified through this interface as 10.15. When using the
<Availability.h> equivalent, __MAC_OS_X_VERSION_MAX_ALLOWED, the 11.0
SDK is identified as 10.16 (arguably it should be internally versioned
as 11.0, but at least this interface allows it to be detected
unambiguously.) It’s clear that the <AvailabilityMacros.h> interface
provides no meaningful support for the macOS 11.0 SDK at all, but
<Availability.h> does.
<Availability.h> was introduced in the Mac OS X 10.5 SDK, so there is no
relevant SDK version compatibility problem with this interface.
Key differences between these interfaces for the purposes used by
Crashpad:
- <AvailabilityMacros.h> → <Availability.h>
- MAC_OS_X_VERSION_MIN_REQUIRED (DT) → __MAC_OS_X_VERSION_MIN_REQUIRED
- MAC_OS_X_VERSION_MAX_ALLOWED (SDK) → __MAC_OS_X_VERSION_MAX_ALLOWED
- MAC_OS_X_VERSION_x_y → __MAC_x_y
- <Availability.h> __MAC_OS_X_VERSION_* SDK/DT macros are only
available when targeting macOS, while <AvailabilityMacros.h>
MAC_OS_X_VERSION_* SDK/DT macros are available on all Apple platforms,
which may be a source of confusion. (<Availability.h> __MAC_* macros
do remain available on all Apple platforms.)
This change was made mostly mechanically by:
sed -i '' -Ee 's/<AvailabilityMacros.h>/<Availability.h>/g' \

In contrast to macOS on x86, there’s no need to support 32-bit arm on
macOS, because this new platform is 64-bit-only from its inception.

If the file just needs the CHECK/CHECK_OP/NOTREACHED
macros, use the appropriate header for that instead.
Or if logging.h is not needed at all, remove it.
This is both a nice cleanup (logging.h is a big header,
and including it unnecessarily has compile-time costs),
and part of the final step towards making logging.h no
longer include check.h and the others.

The “and not memory after range” follow-up to the “extra memory range
captured” test is very flaky in debug builds
(https://ci.chromium.org/p/crashpad/builders/ci/crashpad_win_dbg/388),
and occasionally flaky in release builds too
(https://ci.chromium.org/p/crashpad/builders/ci/crashpad_win_rel/363).
As with the already-disabled “extra memory removal” test, it’s likely
that Crashpad is discovering a pointer that references the memory
immediately beyond the intended range, and capturing that too. Unless
the environment is very tightly controlled, it’s difficult to prevent
valid memory from being pointed to, and thus to guarantee that Crashpad
won’t capture a particular block of memory.
These are probably never going to be fixed. The flaky tests are removed.

In a stack overflow test from the Fuchsia tree, an intentional crash was
being induced that at the point it was reported to Crashpad resulted in
a stack pointer outside of the stack. This caused two problems:
- Crashpad attempted to capture that whole "thing" which could have been
anything, and in the failing test was a 1G guard region
- The whole wrong thing could be very large, resulting in OOM when
trying to write the minidump, which was the symptom of the bug.
Don't attempt to continue of SP isn't at least in a mapping, and don't
capture too-large regions for the stack as nothing useful can come of
that anyway.
New test added: ProcessSnapshotFuchsiaTest.InvalidStackPointer.

Use the new standard pattern, and remove all vestiges of the custom

This was done previously in 79f4a3970a64, but was reverted in

GTEST_SKIP() at the time. The deficiency is on file as

macOS 10.15 (“Catalina”) introduces a single new field to its
dyld_all_image_infos structure, and uses structure version 16.
macOS 10.13 and 10.14 were documented in <mach-o/dyld_images.h> as using
structure version 16, but they actually use version 15. They should have
used version 16, as they do use a structure expanded from macOS 10.12,
which also uses version 15. Previously, process_types was true to the
documentation, but now that this is known to be incorrect, it’s been
revised to reflect reality. Because two variants of the version 15
structure exist, run-time OS version detection is used to disambiguate.

This allows partial reading of the current process (e.g. modules or
CrashpadInfo), even though the memory map read (and so thread retrieval)
will fail if ProcessSnapshotFuchsia is used on the current process.
This is a follow up to
db6f51d3fc
which broke the CrashpadInfoClientOptions.* tests.

From looking at some syzkaller logs, the earliest error seems to be
[...ERROR memory_map_fuchsia.cc:47] zx_object_get_info ZX_INFO_PROCESS_MAPS: ZX_ERR_BAD_STATE (-20)
which might be caused by a failure to suspend. That error causes
ProcessReaderFuchsia's memory_map_ Initialize() to fail, but that was
mistakenly being ignored. Later calls then fail as well.
While we're here, also check a couple other Initialize()s that were
sometimes triggering later on.

When a crash dump request is received over a socket, the message
includes a stack address of the thread requesting the dump. This can
be used to override the ExceptionInfo's thread ID which may be
incorrect in the handler's PID namespace.

Stack mappings can be enormous for some processes dwarfing all other
data and making the .dmp useless. It isn't useful to capture beyond the
stack pointer, so grab only from the stack base to the stack pointer.
In the default config (safestack enabled), this isn't a major problem.
However, Chromium has safestack disabled, along with a large stack size,
so dumps with many threads become very large.

This test will break if there is an unusual character in the vendor
string. Moreover, std::regex is banned in Chromium so the test is
blocking the roll.
Probably all that can meaningfully be tested here is that the vendor
string is non-empty, so do that instead.

When a crashing process is in a different PID namespace than the
handler, the crasher doesn't have a way of knowing its own thread ID in
the handler's namespace and the kernel lacks mechanisms to perform this
translation before Linux 4.1 (where the information is present in
/proc/<pid>/status:NSPid).
This patch gives the handler a way of identifying the requesting thread
by sending a stack address along with the crash dump request, which
the handler can search for in each of the process' threads.
This information is useful both for attaching exception information
to the right thread and to allow the handler to send signals to the
correct thread when using a shared socket connection.

As of Android Q, the android_set_abort_message() function copies the
abort message into a mapping with a specific name that starts with a magic
number. This makes it possible for Crashpad to collect the abort message
by looking for the mapping with this name in procmaps and checking for the
magic number. The abort message is stored in a process annotation named
"abort_message".
