This works around a bug in M that prevents Breakpad from using
ftruncate() in the renderer process.
To do this, skip the calls to ftruncate() when allocating bigger
minidump files and strictly depends on write() to append to the end.
It might be less efficient but this is probably less of an issue on
SD cards. It is much better than not getting crash reports.

There is an issue in StackwalkerAMD64::GetCallerByFramePointerRecovery.
Occasionally it produces invalid frames (instruction pointer == 0) which
prevents the AMD64 stack walker from proceeding to do stack scanning and
instead leads to premature termination of the stack walking process.

Debug Gecko builds don't build with -D_DEBUG, so the ifdef in
crash_generation_server doesn't work right. The MSDN documentation for
assert says that it's enabled based on the absence of the NDEBUG define,
so using that seems sensible.

than 2013.
The Windows client gyp files were missing proc_maps_linux.cc for the
unittest build. Adding that revealed some build errors due to it
unconditionally including <inttypes.h>. Removing the workarounds in
breakpad_types.h (and a few other places) made that build, which means
that Visual C++ 2013 is now our minimum supported version of MSVC.
Additionally I tried building with VC++ 2015 and fixed a few warnings
(which were failing the build because we have /WX enabled) to ensure
that that builds as well.

Chrome started hitting some crashes in v8 jitted code which happens to be
non ABI compliant and debuggers (including WinDBG) are unable to produce
meaningful stack traces.
The Breakpad stack walker has some builtin heuristics to deal with such cases.
More specifically, when unable to find a good parent frame, it scans the raw
stack to find a suitable parent frame. The max scan size was set at 30
pointers which was (apparently) not enough to recover in this case.
I'm increasing it to 40 pointers. I confirmed that at 34 pointers it was able
to recover however I'm setting it to 40 in order to it some slack.
I needed to update two unittests which were expecting the previous scan limit.

This patch allows dump_syms to handle S_THREAD_LOCAL_ZEROFILL
and S_GB_ZEROFILL section in the same way as the more common
S_ZEROFILL section. Previously, dump_syms would fail to dump
a binary containing a __DATA,__thread_bss section, because it
tried to look up its data (and failed).

Although strictly the GPU fingerprint is defined by the build fingerprint,
there is not currently a straightforward mapping from build fingerprint
to useful GPU / GL driver information.
In order to aid debugging of WebView crashes that occur in GL drivers,
and to better understand the range of drivers and versions for feature
blacklisting purposes, it is useful to have GPU fingerprints in breakpad
microdumps.

On Android the size of the alternate stack can be very small (8k).
Even if breakpad uses sigaltstack to increase the size of the alternate
stack during initialization, that call affects only the main thread.
On Android, the libc's pthread initializer reset the sigaltstack to 8k.
When entering a signal handler, the kernel typically pushes the context
on the alternate stack. On arm64, sizeof(CrashContext) is ~5k, which
leaves 3k of usable stack for breakpad.
On top of that, breakpad allocates another struct CrashContext on the
stack. In the case of Android arm64, then, breakpad ends up using
5k + 5k > 8k of stack, which causes a stack overflow.
This got unnoticed in Android L, as the alternate stack didn't have
red-zones between them, so breakpad was often happily overflowing onto
the next thread's stack. This is not the case anymore [1].
This CL moves the CrashContext into a global variable. It should be
safe as the ExceptionHandlers are serialized on a mutex.

We're working on building our Firefox Mac builds as a Linux cross-compile
(https://bugzilla.mozilla.org/show_bug.cgi?id=921040) and we need symbol
dumping to work. This change ports the Mac dump_syms tool to build and work
on Linux. I've tested it and it produces identical output to running the
tool on Mac.
The bulk of the work here was converting src/common/mac/dump_syms.mm and
src/tools/mac/dump_syms/dump_syms_tool.mm from ObjC++ to C++ and removing
their use of Foundation classes in favor of standard C/C++.
This won't compile out-of-the-box on Linux, it requires some Mac system
headers that are not included in this patch. I have those tentatively in
a separate patch to land in Gecko
(http://hg.mozilla.org/users/tmielczarek_mozilla.com/mc/rev/5fb8da23c83c),
but I wasn't sure if you'd be interested in having them in the Breakpad tree.
We could almost certainly pare down the set of headers included there, I
didn't spend too much time trying to minimize them (we primarily just need
the Mach-O structs and a few associated bits).
I just realized that this patch is missing updating the XCode project files
(ugh). I'll fix that up in a bit.

O A arm 04 armv7l 3.4.0-perf-g4d6e88e #1 SMP PREEMPT Mon Mar 30 19:09:30 2015
and currently the field that says "armv7l" or "aarch64" is being used
to fill in the CPU arch field in crash. The problem is that on a
64-bit device this field *always* says "aarch64" even when running in
a 32-bit process, and so currently the crash reports for aarch64 are
a mix of 32-bit and 64-bit crashes. We should be using the first field
instead, which just says "arm" or "arm64" and reflects the actual
version of webview (32-bit or 64-bit) which is running.

If a crash occurred as a result to a write to unwritable memory, it is reason
to suggest exploitability. The processor checks for a bad write by
disassembling the command that caused the crash by piping the raw bytes near
the instruction pointer through objdump. This allows the processor to see if
the instruction that caused the crash is a write to memory and where the
target of the address is located.

Android's sys/user.h is missing user_regs_struct and user_fpsimd_struct.
Add them to the Android specific user.h used by breakpad to workaround
Android / glibc compatibility issues.
A bug has been filed on the Android NDK team to add the missing structures to
the NDK, at which point this hack can be removed.
Also remove the mxcsr_mask hack on x64, which is no longer required since
we have moved to the r10d NDK which fixes this issue.

The PopSeccompStackFrame was introduced to deal with stack frames
originated in the legacy seccomp sandbox. The only user of that
sandbox was Google Chrome, but the legacy sandbox has been
deprecated in 2013 (crrev.com/1290643003) in favor of the new
bpf sandbox.
Removing this dead code as it has some small bound checking bug
which causes occasional crashes in WebView (which are totally
unrelated to the sandbox).
Note: this will require a corresponding change in the chromium
GYP/GN build files to roll.

So far the microdump_writer dumped the log in logcat using the default
system log. This is simple to achieve but has some drawbacks:
1. Creates spam in the system log, pushing back other eventual useful
messages.
2. There is a high chance that the microdump gets lost if some log
spam storm happens immediately after a crash and before the log
is collected by the feedback client.
3. Since Android L, the logger is smartly throttling messages (to
reduce logcat spam). Throttling brekpad logs defeats the all
point of microdumps.
This change is conceptually very simple. Replace the use of
__android_log_write() with __android_log_buf_write(), which takes
an extra bufID argument. The main drawback is that the
__android_log_buf_write is not exported in the NDK and needs to be
dynamically looked up via dlsym.
This choice has been discussed and advocated by Android owners.
See the internal bug b/21753476.

Linux minidumps do not support MD_MEMORY_INFO_LIST_STREAM, meaning the
processor cannot retrieve its memory mappings. However, it has its own
stream, MD_LINUX_MAPS, which contains memory mappings specific to Linux
(it contains the contents of /proc/self/maps). This CL allows the minidump
to gather information from the memory mappings for Linux minidumps.
In addition, exploitability rating for Linux dumps now use memory mappings
instead of checking the ELF headers of binaries. The basis for the change
is that checking the ELF headers requires the minidumps to store the memory
from the ELF headers, while the memory mapping data is already present,
meaning the size of a minidump will be unchanged.
As a result, of removing ELF header analysis, two unit tests have been removed.
Arguably, the cases that those unit tests check do not merit a high
exploitability rating and do not warrant a solid conclusion that was given
earlier.

The exploitability rating for a dump is EXPLOITABILITY_NOT_ANALYZED if the
exploitability engine in not enabled, not EXPLOITABILITY_NONE.

The thread info expects the struct names as they expect in asm/ptrace.h,
but the header doesn't include that, it includes sys/user.h. Rename the
reg structs to match that header.
Rename the elf_siginfo to _elf_siginfo to avoid conflicting with the one
in the sys/procfs.h. It is only used locally in one place, so we don't
need to update any callers.
Otherwise, drop in aarch64 support into the minidump-2-core file.

When LLVM sees an attempt to dereference a NULL pointer, it will generate
invalid opcodes (undefined behavior) which leads to SIGILL which breaks
this unittest. Upstream's recommendation in this case is to add volatile
markings to get the actual dereference to happen.
This is documented in the blog post under "Dereferencing a NULL Pointer":

If the minidump module containing the instruction pointer has memory
containing the ELF header and program header table, when checking the
exploitability rating, the processor will use the ELF header data to determine
if the instruction pointer lies in an executable region of the module, rather
than just checking if it lies in a module.
