The broker attempts to use sbrk() to allocate memory to track ptrace
attachments. If the process failed due to an OOM, this system call might
fail, the broker falls back to saving attachments on the stack, and then
overruns the stack.
This change updates the broker to use sys_mmap() instead of sbrk(),
which is expected to work at least as well. If sys_mmap() fails or
the first mapped page is exhausted, further attachments fail without
attempting to save them to the stack.

Previously, these tests expected a specifically formatted prefix to log

prefix.
This change updates the tests to expect log messages at the end of a log
line, but ignores the prefix.

LogOutputStreamTest.{WriteAbort,FlushAbort} are flaky because the logcat
is sometimes overloaded earlier than expected causing FlushAbort to fail
during Write() or either test to fail to write the abort message.
This change updates LogOutputStream to detect logcat overloads (EAGAIN)
and make one attempt at writing the abort message, even if the output
cap hasn't been reached.
This change also updates LogOutputStream's interface to defer log writes
to a Delegate. In tests, the Delegate implements a mock log and in
production, writes to Android's logcat.
I've removed VerifyGuards because LogOutputStream no longer writes
guards if Write() has never been called and the guards are tested in
other tests.

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' \
$(git grep -E -l '<AvailabilityMacros.h>' |
grep -v AvailabilityMacros.h)
sed -i '' -Ee 's/(MAC_OS_X_VERSION_(MIN_REQUIRED|MAX_ALLOWED))/__\1/g' \
$(git grep -E -l 'MAC_OS_X_VERSION_(MIN_REQUIRED|MAX_ALLOWED)' |
grep -v AvailabilityMacros.h)
sed -i '' -Ee 's/(MAC_OS_X_VERSION_(10_[0-9]+))/__MAC_\2/g' \

This updates the way that the .defs files added in 1bfd7d06ed60 are
treated, by putting them in compat/ios, using compat as intended. The
.defs files in compat forward, via #include, to the ones in
third_party/xnu. Additionally, compat/mac is enabled for iOS, as
everything in compat/mac is sensible on iOS, and will have no effect
when rendered unnecessary by the iOS SDK.
This also changes util:mig_output to a static_library instead of a
source_set. I don’t think there was any reason for it to have been a
source_set to begin with. static_library is preferred for nearly
everything.

This makes UniversalMachExcServer available on iOS.
UniversalMachExcServer is the foundation for a Mach exc and mach_exc
server.
Some code in UniversalMachExcServer needs to be evaluated to ensure that
portions that run in the same process that has sustained the exception
are safe to do so at that time. For example,
SimplifiedExcServer<ExcTraits>::Interface instantiates and appends to a
std::vector<>, which is generally unsafe in this context. However, that
code responds to exc requests. The mach_exc equivalent,
SimplifiedMachExcServer<MachExcTraits>::Interface, does not use a vector
at all.
This also enables support code in the form of CompositeMachMessageServer
and UniversalExceptionRaise, all of the tests for
CompositeMachMessageServer, and most of the test for
exc_server_variants.cc. The multiprocess-based exc_server_variants tests
remain disabled on iOS.

mig was being invoked without any -arch argument, causing it to assume
the build system’s native architecture, which would be x86_64. This is
not correct for iOS device builds, which use arm64. The -arch argument
must be plumbed to mig for correct behavior.
When building for iOS, mig was being invoked without any -isysroot
argument, causing it to use the root for the build system, which runs
macOS and not iOS. The macOS SDK doesn’t include the ARM definitions
needed for iOS device builds.
<mach/exc.defs> and <mach/mach_exc.defs> depend on a small number of
other .defs files to provide definitions of standard types. All .defs
files are absent from the iOS SDK. These .defs files are borrowed from
xnu and placed in third_party/xnu. An additional --include argument is
added to allow mig to locate these files.

This updates (and corrects) 8dbbaff2e1a5, which added exc.defs, by
adding mach_exc.defs too.
The difference betwen the exc and mach_exc subsystems is that the |code|
parameter is int[] in exc and int64_t[] in mach_exc. Many exceptions
carry the exception address in code[1], and a 32-bit int results in the
exception address being truncated in exc. No information is lost in
mach_exc, where a 64-bit int64_t is used.
In 8dbbaff2e1a5, I misremembered the type of the |code| parameter as a
type derived from uintptr_t, such as vm_address_t, an integer as wide as
a pointer. I was wrong, and mach_exc is necessary. I also noted that
Apple normally forbids mach_-prefixed interfaces in favor of the
prefix-less ones for the reasons I mentioned, and that, all else being
equal, it was desirable to adhere to the spirit of that convention.
Because neither exc nor mach_exc are available in the SDK, it’s moot
from a technical perspective, as we need to provide our own stubs either
way.

This enables the following code in util/mach on iOS:
- exception_behaviors.{cc,h}
- exception_ports.{cc,h}
- mach_message.{cc,h}
- mach_message_server.{cc,h}
Only the ExceptionBehaviors and MachMessage tests are built, because the
other two are tested by multiprocess tests that won’t run on iOS.
The AuditPIDFromMachMessageTrailer function from mach_message.h is
excluded on iOS because it relies on <bsm/libbsm.h>, which is broken on
iOS: it depends on <bsm/audit_record.h>, which is missing from the SDK.
Additionally, the BSM function that Crashpad uses, audit_token_to_au32,
is marked as unavailable on iOS. Crashpad uses it on macOS to
authenticate Mach messages sent by other processes, but this is moot on
iOS.

The iOS SDK doesn’t include a copy of <mach/exc.defs>. It only provides
<mach/exc.h>, which is just the user-side header. To obtain declarations
and implementations of the server-side stubs, a current copy of
<mach/exc.defs> is added to third_party, and the mig action in util is
updated to use it on iOS.
The three other mig subsystems that Crashpad uses are not brought to
iOS:
- mach_exc is identical to exc except it always uses 64-bit quantities
for addresses in place of exc’s use of quantiies sized for native
pointers. Because all iOS work is limited to a single process, there
is no need to consider cross-process operation with variable bitness,
so mach_exc is unnecessary. We’re also only targeting 64-bit for iOS,
so exc will always suffice. This follows the spirit of other
mach_-prefixed routines on iOS, where Apple forbids mach_vm_read to
user applications but permits vm_read.
- notify is primarily used on macOS in the Crashpad handler process to
receive a no-senders notification, which is used to trigger handler
shutdown when it has no more clients. This is not believed to be
useful to Crashpad on iOS, which is restricted to single-process
operation.
- child_port is a Crashpad-specific subsystem used to pass Mach rights
between processes, but is similarly useless when restricted to
single-process operation as on iOS.

When code raises an Objective-C exception, unwind the stack looking for
any exception handlers. If an exception handler is encountered, test to
see if it is a function known to be a catch-and-rethrow 'sinkhole'
exception handler. Various routines in UIKit and elsewhere do this, and
they obscure the exception stack, since the original throw location is
no longer present on the stack (just the re-throw) when Crashpad
captures the crash report. In the case of sinkholes, trigger an
immediate exception to capture the original stack.
The is an improvement over the alternative,
NSSetUncaughtExceptionHandler, which passes along the stack frames, but
not the stack memory contents and full exception context itself.
The details of what happens after a fatal exception is triggered are
unresolved in this CL. For now, simply call std::terminate.
This code was inspired by chromium/src/chrome/browser/mac/
exception_processor.mm.

Bionic installs signal handlers which request crash
dumps from Android's debuggerd, but there are errors
in how signals which aren't automatically re-raised
are handled on Marshmallow (API 23).
Before requesting a dump, Bionic acquires a lock to
communicate with debuggerd and expecting imminent
death, never releases it.
While handling the dump request, debuggerd allows
the dying process to continue before
ptrace-detaching it. So, when Bionic manually
re-raises a signal, it is intercepted by debuggerd
and the dying process is allowed to live.
Bionic restores SIG_DFL for the signal it's just
handled, but if a different crash signal is later
recieved, Bionic attempts to reacquire the lock to
communicate with debuggerd and blocks forever.
Disable Bionic's signal handlers for these signals
on Marshmallow.

Since _ZN8crashpad14CaptureContextEP10ucontext_t wasn't marked as a function,

crashpads non-thumb assembly (in arm32).
So mark the symbol as function, so that things work even if that patch

I also did this for aarch64 since it seems like The Right Thing To Do

main thread. The start time is returned in a timeval, with microsecond
precision, but the measurement of boot time requires two system calls
and the time between those system calls can be approximately a
microsecond. An unlucky event such as a change in system time could
make this imprecision arbitrarily bad.
This patch lets the caller of ProcStatReader.StartTime() inject the
boot time, allowing ProcStatReader to guarantee that threads have

As a workaround, use a prebuilt .obj file when the Microsoft-dialect

The obj file is generated from the capture_context_win_arm64.asm
by armasm64 macro assembler. If this asm file is modified,

This patch also updates WorkerThread to execute DoWork() when
DoWorkNow() has been called, which is relevant when DoWorkNow() and
Stop() have both been called. This occurs regularly on Android where
the handler's current normal mode is to dump a single process and exit.
This change ensures the upload thread has a chance to upload the report
before the handler exits.
This change should not affect upload on Chrome/WebView/Chromecast which
don't pass Crashpad a --url option and are still responsible for their
own uploads.

sendmsg() and recvmsg() are complicated to use. Refactor their usage
into functions with a simpler, tested interface and use those instead.
This also adds CreateCredentialSocketpair() to create a pair of
connected sockets with SO_PASSCRED set. This option should be set
before the possibility of any calls to sendmsg() with the socket pair
to avoid race conditions in properly setting credentials.
Also update the handler to use Strategy::kNoPtrace (which causes the
crash dump to fail without breaking the socket connection) if the
credentials were invalid, which can happen if SO_PASSCRED was set after
the call to sendmsg() or if the sending process does not exist in this

This connection mode does not support using a broker process which

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.

zx_task_suspend() now supports suspending processes. This is somewhat
more reliable than suspending the constituent threads because after the
call returns and the token is being held, any subsequently started
threads will start in the the suspended state.
However, because the suspend is asynchronous the threads of the process
still need to be iterated to wait for them to assert ZX_THREAD_SUSPENDED
(and that can and does still fail to happen for a number of reasons). So
while improved, this class is still only best-effort.
Additionally, as the version of ScopedTaskSuspend that took a thread

Currently, TaskMemory::ReadCStringInternal() treats the
ReadCStringSizeLimited(size=0) case by returning an empty string;
however, that is inconsistent with the documentation for that function
and the equivalent implementation in ProcessMemory. The comment for the
size parameter is: "The maximum number of bytes to read. The string is
required to be `NUL`-terminated within this many bytes." My
interpretation is that the ProcessMemory behavior is correct in failing
on size=0 as a NUL can never be read.
ReadCStringSizeLimited() is only used with a possibly null size in
MachOImageReader::ReadDylinkerCommand(). In that case we read the
dylinker_command string, which appears to also be verified to be a
non-zero length null terminated string in load_dylinker() in
bsd/kern/mach_loader.c so we shouldn't hit this case in the wild.

Beginning with API 21, Bionic provides android_dlopen_ext() which
allows passing a file descriptor with an existing relro segment to the
loader. This means that the mapping containing the dynamic segment
could have a name, device, and inode which are different than the
other mappings for the module.
The revised strategy for Android at API 21+ is to search all mappings
in reverse order from they dynamic array mapping until a module is
parsed with the expected dynamic array address.
Linux and Android 20- continue to select mappings using the device,
inode, and file offsets of the mappings.

Currently, ProcessMemory is only implemented for Linux and Fuchsia.
Implement the interface for Windows as well and re-factor tests to
support it, mostly this consists of using a new ScopedGuardedPage class
instead of ScopedMmap in the ProcessMemory tests.

The HTTPS tests are flaky on Fuchsia bots, so TLS transport was disabled.
However, a different CHECK fails in prod when a crash is attempted to be
uploaded via an 'https' url. So for now, re-enable the https transport,
but disable the https tests that were flaky, so they can be debugged
separately.
Additionally, there was a small error in
21edfd3c3a
that wasn't caught because these tests were disabled; fix the path to
test server certs on Fuchsia.

The build broke because x30 was used instead of r14 in place of LR
which gcc doesn't recognize when building for 64-bit ARM. gcc does
recognize LR for 32-bit ARM, however, so revert to that since it's
more readable.
Also, de-duplicate saving of FP/IP which are synonyms of r11/r12,
saved above.

The general strategy used by Crashpad to determine loaded modules is to
read the link_map to get the addresses of the dynamic arrays for all
loaded modules. Those addresses can then be used to query the MemoryMap
to locate the module's mappings, and in particular the base mapping
from which Crashpad can parse the entire loaded ELF file.
ELF modules are typically loaded in several mappings with varying
permissions for different segments. The previous strategy used to find
the base mapping for a module was to search backwards from the mapping
for the dynamic array until a mapping from file offset 0 was found for
the same file. This fails when the file is mapped multiple times from
file offset 0, which can happen if the first page of the file contains
a GNU_RELRO segment.
This new strategy queries the MemoryMap for ALL mappings associated
with the dynamic array's mapping, mapped from offset 0. The consumer
(process_reader_linux.cc) can then determine which mapping is the
correct base by attempting to parse a module at that address and
corroborating the PT_DYNAMIC or program header table address from the
parsed module with the values Crashpad gets from the link_map or
auxiliary vector.
