4773a37f0a Crashpad: Adding PAC bit stripping to stack sanitization.
Pointer Authentication works by adding a signature to the top bits of
an instruction or data pointer (only instruction pointers on the stack
are currently signed in Chromium). This can confuse range checks,
because they need to strip the top bits. Masking these bits during sanitization range checks prevents confusion.


Test: Testing was done manually on a device with pointer authentication enabled.

fdf7b9e8e9 Skip tests that create symbol links when not allowed
Several tests in filesystem_test.cc create symbol links. The privilege
needed to do this is not enabled on all Windows systems so several of
the tests check for the privilege and are skipped if it is not
available.

However, two tests that created symbol links were not doing this check
and therefore failed on some Windows machines. This corrects those
failures by adding the checks.

eeb3cad132 Raise extra-memory cap in ProcessSnapshotTest.CrashpadInfoChild
The extra_memory cap in ProcessSnapshotTest.CrashpadInfoChild is not
high enough to avoid test failures on all machines. The actual amount
recorded has been seen to vary between 726,556 and 1,152,803. This
change rases the limit from 1,000,000 to 1,200,000 to avoid the
failures.

The highest amount was seen on a 64-GB gWindows ThinkPad laptop.

Instrumentation shows that the low and high cases both have 104 threads.
The low case has 304 ExtraMemory() blocks, whereas the high case has
409. In both cases the sizes range from 384 to 6,024.

3cd7b5bf7f ios: Fix crash in ObjcExceptionPreprocessor.
ObjcExceptionPreprocessor is a 'reasonable effort' attempt to catch an
NSException minidump at time the exception is thrown as opposed to when the application terminates due to the exception. If multiple
exceptions are thrown at the same time, Crashpad should correctly
report the final uncaught exception, but the minidump may not
represent the full `caught-at-thrown` minidump.

 - Don't assume ObjcExceptionPreprocessor throws an NSException.
 - Don't retain/release the exception. Instead of calling isEqual,
   just use a simple pointer comparison.
 - Make last_exception atomic.

Adds the dump_minidump_annotations tool (modified from jperaza's WIP
code). This works similarly to Breakpad's minidump_dump tool, but:

1. Is available on Windows
2. Only dumps simple/vectored annotations and annotation objects instead
   of the entire minidump contents.

Current use case for this is to be able to get a minidump's process
type on Windows without having to go through symbolization, but there
may be other use cases in the future.

c7d9c710f2 [ios] Support guarding concurrent reads and writes to Annotations
Since iOS reads Annotations in-process, this CL updates the iOS
intermediate dump handler to check each Annotation to see if it supports
guarding concurrent reads and writes using ScopedSpinGuard.

For any such Annotation, the in-process dump handler now tries (without
spinning) to obtain the ScopedSpinGuard for the Annotation before
reading its memory.

If the ScopedSpinGuard cannot immediately be obtained, the in-process
dump handler just skips writing the memory of the Annotation to the
intermediate dump. (I'd like to follow up and thread down a Params
object so we can experiment with adding an optional timeout to make
this more reliable.)

212b8f6b8c [client] New RingBufferAnnotation
This CL integrates the new ScopedSpinGuard with the new
LengthDelimitedRingBuffer into a new class, RingBufferAnnotation.

RingBufferAnnotation is thread-safe both for reading and writing, and is
suitable for streaming logs, trace events, and other high-throughput
data streams.

I included a load test (ring_buffer_annotation_load_test) which launches
two threads which simultaneously write to and read from the
RingBufferAnnotation.

By default, reads and writes are serialized using ScopedSpinGuard, but
passing the flag "--disable_spin_guard" to the test disables the spin
guard on the reading side (which is expected to make the test fail).

This is useful for Annotations which use ScopedSpinGuard to

dump handler can try to take the spin guard when reading such
an Annotation and skip reading it if it the spin guard could not
be obtained.

1a7918b716 [client] New class LengthDelimitedRingBuffer
This CL implements LengthDelimitedRingBuffer, a general-purpose
ringbuffer suitable for use as a Crashpad Annotation.

This ringbuffer supports writing variably-sized data delimited by a Base
128 varint-encoded length separator.

LengthDelimitedRingBuffer is backed by a std::array, so it has a fixed
maximum size. It supports reading via RingBufferReader as well as
writing via RingBufferWriter.

c902f6b1c9 Fix Crashpad CI failures on mac, linux, and fuchsia
Crashpad CI is currently failing the mac, linux, and fuchsia builds:

The breakage was introduced by https://crrev.com/c/3990128, but CI
didn't start failing until depot_tools started using it in
https://crrev.com/c/3925341 .

This CL fixes two issues in that CL:

2) host_cpu in DEPS is x64, not amd64, for x86_64 platforms

fca8871ca3 Add SA_EXPOSE_TAGBITS to crashpad's signal handler.
SA_EXPOSE_TAGBITS is a Linux >= 5.11 feature that allows si_addr to
contain the upper tag bits. This is a feature that allows signal
handlers to see the full upper address bits on aarch64, which consist of
TBI and MTE nibbles. For MTE, preserving these bits is of significant
importance, as it allows for precise use-after-free and buffer-overflow
diagnosis that's impossible without seeing these bits in the fault
address.

We unconditionally enable this feature on all kernels, as it's ignored
when unsupported (even on older kernels).

Tested on:
 1. Linux x86 host, which is a no-op.

72e51701c7 [MSAN] Suppress false-positive in HTTPTransportLibcurl::WriteResponseBody
This bug was found when trying to upgrading the MSAN bots from Ubuntu
18.04 (where this codepath was not hit) to 20.04.  The following MSAN
error is produced when running HTTPTransport/HTTPTransport.*

  ORIGIN: invalid (0). Might be a bug in MemorySanitizer origin tracking.

The memory is initialized in http_transport_test.cc:293, but MSAN gets
confused.  Given the message output by MSAN (ORIGIN: invalid (0).
Might be a bug in MemorySanitizer origin tracking), this appears
to be a bug in MSAN, not crashpad, so this CL suppresses the error.

a91f197a26 [tests] Make the infinite recursion actually recurse with clang
On gLinux, tests don't pass in the default configuration (empty GN
args), because the infinite recursion test doesn't crash
anymore. Locally, forcing the function to stay out of line is sufficient
to fix it. This is inherently brittle, and may need to be revisited at a
later point.

- Mac: third_party/ninja/mac/ninja
- Windows: third_party/ninja/ninja.exe

This supports a workflow with VMs on the same host machine.

On Unix, `ninja` command wrapper in depot_tools will trigger third_party/ninja/ninja, which call linux or mac ninja.
On Windows, the depot_tools wrapper will trigger third_party/ninja/ninja.exe.

See the the discussions on the previous CL https://crrev.com/c/3924593 for more context.

Fixes locking not working on some Android filesystems due to flock not

non-rooted Android devices, as we need files to be written to a
location accessible without root, but the chosen location might not

833219f1ad [ios] Add optional UploadBehavior enum to InProcessHandler::StartProcessingPendingReports()
Previously, StartProcessingPendingReports() only started the prune and
upload threads if it thought the application was actively running in
the foreground.

However, some Crashpad clients would like to replicate Breakpad's
behavior of allowing uploads while the application is starting up
(before it moves to the foreground).

This CL introdues an optional UploadBehavior enum to
InProcessHandler::StartProcessingPendingReports(), defaulting to the
current behavior of only uploading processed crash reports while the
application is in the foreground.

If the enum is set to UploadBehavior::kUploadImmediately, then
InProcessHandler will start the prune and upload threads regardless
of the application state. (If the application state later transitions
to a non-active state, then InProcessHandler will stop the prune and
upload threads as normal.)

ca3cf2f4e3 [ios] Add an optional upload complete observation callback to the in-process handler

This adds an equivalent observation callback to Crashpad on iOS which is invoked each time an upload attempt completes (whether it succeeds or fails).

I couldn't find any existing unit tests for the upload thread, but
I tested this manually by integrating it into a client. Please
let me know the best way to test this.

54da37c2d2 Remove std::vector from crashpad_wer
When assertions were enabled in Chrome in https://crrev.com/c/3833545,
crashpad_wer now requires libc++ to be explicitly included if compiled
with -std=c++20 because <vector> would now reference symbols defined
outside the libc++ headers. We attempted to add libc++ as a dependency
in https://crrev.com/c/3862974; however, that was deemed unacceptable
because the library needs to be kept small in order for Windows to load
it to handle crashes. Therefore, the only alternative is to update the
library to remove std::vector

bfc0eb5709 Close handler_sock after starting crashpad server.
handler_sock end of the socketpair is donated to the crashpad server
process which owns it. The client should not keep it open. Otherwise
if the crashpad server process crashes and the client is reading from
client_sock, the client will hang forever because the other end is still
open.

This happens when:
- /proc/sys/kernel/yama/ptrace_scope file is present.
- crashpad is invoked with missing required fields, like --database.

In this case, chrome hangs until timeout.

On iOS, holding a lock during a slow upload can lead to watchdog kills
if the app is suspended mid-upload. Instead, if the client can obtain
the lock, the database sets a lock-time file attribute and releases the
flock. The file attribute is cleared when the upload is completed. The
lock-time attribute can be used to prevent file access from other
processes, or to discard reports that likely were terminated mid-upload.

Adds a new IOSIntermediateDumpWriter::AddPropertyCString method which
takes an address to a cstring of unknown length and page-by-page
searches for a NUL-byte terminator.

This is necessary because currently WriteModuleInfo calls strlen
directly on the dyld and module filePath without first using vm_read.
On iOS14 this occasionally crashes, and is generally unwise. Instead,
use AddPropertyCString.

This patch also removes WriteDyldErrorStringAnnotation, as it's no
longer used going forward with iOS 15.

80520bd937 Add WER runtime exception helper module for Windows
This adds a runtime exception helper (& test module) for Windows and
plumbing to allow the module to be registered by the crashpad client,
and to trigger the crashpad handler. Embedders can build their own
module to control which exceptions are passed to the handler.

See: go/chrome-windows-runtime-exception-helper for motivation.

When registered (which is the responsibility of the embedding
application), the helper is loaded by WerFault.exe when Windows
Error Reporting receives crashes that are not caught by crashpad's
normal handlers - for instance a control-flow violation when a
module is compiled with /guard:cf.

Registration:

The embedder must arrange for the full path to the helper to
be added in the appropriate Windows Error Reporting\
RuntimeExceptionHelperModules registry key.

Once an embedder's crashpad client is connected to a crashpad
handler (e.g. through SetIpcPipeName()) the embedder calls
RegisterWerModule. Internally, this registration includes handles
used to trigger the crashpad handler, an area reserved to hold an
exception and context, and structures needed by the crashpad handler.

Following a crash:

WerFault.exe handles the crash then validates and loads the helper
module. WER hands the helper module a handle to the crashing target
process and copies of the exception and context for the faulting thread.

The helper then copies out the client's registration data and
duplicates handles to the crashpad handler, then fills back the various structures in the paused client that the crashpad handler will need.

The helper then signals the crashpad handler, which collects a dump then
notifies the helper that it is done.

Support:

WerRegisterExceptionHelperModule has been availble since at least
Windows 7 but WerFault would not pass on the exceptions that crashpad
could not already handle. This changed in Windows 10 20H1 (19041),
which supports HKCU and HKLM registrations, and passes in more types of
crashes. It is harmless to register the module for earlier versions
of Windows as it simply won't be loaded by WerFault.exe.

Tests:

snapshot/win/end_to_end_test.py has been refactored slightly to
group crash generation and output validation in main() by breaking
up RunTests into smaller functions.

As the module works by being loaded in WerFault.exe it is tested
in end_to_end_test.py.

The DoubleForkAndExec() function was taking over 622 milliseconds to run
on macOS 11 (BigSur) on Intel i5-1038NG7. I did some debugging by adding
some custom traces and found that the fork() syscall is the bottleneck
here, i.e., the first fork() takes around 359 milliseconds and the
nested fork() takes around 263 milliseconds. Replacing the nested fork()
and exec() with posix_spawn() reduces the time consumption to 257
milliseconds!

See https://github.com/libuv/libuv/pull/3064 to know why fork() is so
slow on macOS and why posix_spawn() is a better replacement.

Another point to note is that even base::LaunchProcess() from Chromium
calls posix_spawnp() on macOS -

3ae34b169b [test] Fix test build failures in Chromium
Importing Crashpad into Chromium revealed a few build failures:

1) The MSVC compiler needed assistance constructing SleepingThreads

2) scoped_set_thread_name_posix.cc did not build on Android, where
   BUILDFLAG(IS_LINUX) is not defined and __ANDROID_API__ must be
   set to 24 or higher to use pthread_getname_np()

This fixes the build failures, which I tested with a Chromium CQ
dry-run:

2bf08e6223 Detect blocked signal installation by sanitizers
Sanitizers can prevent the installation of signal handlers, but
sigaction would still return 0 (for success). Detect this by checking
the installed signal handler via a second call to sigaction.

0a14d52dad Update buildtools (gn and clang-format)
This updates buildtools to 8b16338d17cd. gn has migrated out of
buildtools and into its own cipd package, so gn is pulled at
2ecd43a10266 (current). This provides a mac-x86_64 or mac-arm64 gn as
appropriate for the host CPU architecture. The buildtools update also
brings distinct clang-format executables for mac-x86_64 and mac-arm64 as
appropriate.

816c5572b8 Lazy load settings in CrashReportDatabase.
Before this patch, settings.dat is read from and written to during
database initialization. This happens within Crashpad for iOS, and
within Chrome during startup here:
https://source.chromium.org/chromium/chromium/src/+/main:components/crash/core/app/crashpad.cc;l=209
These are blocking calls on the main thread.

CrashReportDatabaseMac::Initialize will still fail if the various
directory create/ensure calls fail.
