This preserves full build ids in minidumps, which are useful for
tracking down the right version of system libraries from Linux
distributions.
The default build id produced by GNU binutils' ld is a 160-bit SHA-1
hash of some parts of the binary, which is exactly 20 bytes:
https://sourceware.org/binutils/docs-2.26/ld/Options.html#index-g_t_002d_002dbuild_002did-292
The bulk of the changes here are to change the signatures of the
FileID methods to use a wasteful_vector instead of raw pointers, since
build ids can be of arbitrary length.
The previous change that added support for this in the processor code
preserved the return value of `Minidump::debug_identifier()` as the
current `GUID+age` treatment for backwards-compatibility, and exposed
the full build id from `Minidump::code_identifier()`, which was
previously stubbed out for Linux dumps. This change keeps the debug ID
in the `dump_syms` output the same to match.

The Linux dumpers use absolute paths for shared libraries referenced by
dumps, so they fail to locate them if the crash originated in a chroot.
This CL enables callers to specify a root prefix, which is prepended to
mapping paths before opening them.

If the Linux minidump writer crashes while writing a dump, the dump
might contain some useful information, but the header will be empty
because TypedMDRVA's destructor flushes the data, and the header var
doesn't go out of scope until the end of the `Dump` method. This
fixes that problem by putting the header in a shorter block scope.
We've seen this problem in some Android dumps in the wild, like:

This reverts CL https://codereview.chromium.org/1563223004/
This reverts commit 7cc0d8562bf8b20b88cc941ba72593cb7230ecf6.
CL 1563223004 introduces two bugs on iOS.
- Encoding the minidump name with extra percent causing crash server to fail
processing the file.
- Using a released pointer causing random crashes on upload. The
data, resp, err pointers returned in the NSURLSession completion
handler is released at the end of the block. When used later (to get
the crash ID), it causes a crash.

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.

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.

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.

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.

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

Shared libraries containing Android packed relocations have a load
bias that differs from the start address in /proc/$$/maps. Current
breakpad assumes that the load bias and mapping start address are
the same.
Fixed by changing the client to detect the presence of Android packed
relocations in the address space of a loaded library, and adjusting the
stored mapping start address of any that are packed so that it contains
the linker's load bias.
For this to work properly, it is important that the non-packed library
is symbolized for breakpad. Either packed or non-packed libraries may
be run on the device; the client detects which has been loaded by the
linker.

This is to add build fingerprint and product name/version to

The current code is relying on info->si_pid to figure out whether
the exception handler was triggered by a signal coming from the kernel
(that will re-trigger until the cause that triggered the signal has
been cleared) or from user-space e.g., kill -SIGNAL pid, which will NOT
automatically re-trigger in the next signal handler in the chain.
While the intentions are good (manually re-triggering user-space
signals), the current implementation mistakenly looks at the si_pid
field in siginfo_t, assuming that it is coming from the kernel if
si_pid == 0.
This is wrong. siginfo_t, in fact, is a union and si_pid is meaningful
only for userspace signals. For signals originated by the kernel,
instead, si_pid overlaps with si_addr (the faulting address).
As a matter of facts, the current implementation is mistakenly
re-triggering the signal using tgkill for most of the kernel-space
signals (unless the fault address is exactly 0x0).
This is not completelly correct for the case of SIGSEGV/SIGBUS. The
next handler in the chain will stil see the signal, but the |siginfo|
and the |context| arguments of the handler will be meaningless
(retriggering a signal with tgkill doesn't preserve them).
Therefore, if the next handler in the chain expects those arguments
to be set, it will fail.
Concretelly, this is causing problems to WebView. In some rare
circumstances, the next handler in the chain is a user-space runtime
which does SIGSEGV handling to implement speculative null pointer
managed exceptions (see as an example
http://www.mono-project.com/docs/advanced/runtime/docs/exception-handling/)
The fix herein proposed consists in using the si_code (see SI_FROMUSER
macros) to determine whether a signal is coming form the kernel
(and therefore just re-establish the next signal handler) or from
userspace (and use the tgkill logic).
Repro case:
This issue is visible in Chrome for Android with this simple repro case:
- Add a non-null pointer dereference in the codebase:
*((volatile int*)0xbeef) = 42
Without this change: the next handler (the libc trap) prints:
F/libc ( 595): Fatal signal 11 (SIGSEGV), code 1, fault addr 0x487
where 0x487 is actually the PID of the process (which is wrong).
With this change: the next handler prints:
F/libc ( 595): Fatal signal 11 (SIGSEGV), code 1, fault addr 0xbeef
which is the correct answer.

Despite the fact that many places imply that sigaction and rt_sigaction
are essentially the same, rt_sigaction's signature is actually
different-- it takes the size of the kernel's sigset_t as an extra argument.

With this change Breakpad can be compiled for MIPS64,
but it is not yet functional.

__NR_sigaction is not defined on arm64/x64/etc (or rather, it's defined
in unistd-32.h instead of unistd.h).

On Android L+, signal and sigaction symbols are provided by libsigchain
that override the system's versions. There is a bug in these functions
where they essentially ignore requests to install SIG_DFL.
Workaround this issue by explicitly performing a syscall to
__NR_rt_sigaction to install SIG_DFL on Android.

This is a reland of the previous CL (r1433). r1433 did not achieve what
intended and failed the x86_64 build of Chrome with NDK r10c.
The workaround logic in this CL is identical to r1433, but the #define
magic is applied in a more appropriate proper place this time. Turns
out Breakpad already has an Android compatibility layer, which is
common/android/include. Piggybacking the fix there.

r1397 did introduce a workaround to deal with a typo in sys/user.h
in the Android NDK. The typo has been fixed in [1]. However, breakpad
cannot just switch to the fixed version as this would require atomic
rolls of Breakpad and NDK in chromium, which would make reverts hard
to handle.
This change introduces an inelegant yet functional hack which makes
breakpad compatible with both versions of the NDK, with and without
the typo. It can be reverted once Chrome has stably rolled to NDK
r10d.

A recent change in the client-side microdump write (r1404) ended up
introducing a call to new() to instantiate the line buffer that
microdump uses to dump its lines. new/malloc is a luxury we cannot
afford in a compromised context.
This change switches the line buffer to be backed by the dumper
page allocator, which on Linux/Android ends up requesting pages
via mmap.
Also, the microdump write bails out without crashing if the page
allocator failed (crash during severe OOM).

A computation in the stack unwind algorithm could cause an overflow if a base
pointer read from crashed process is sufficiently close to top of address space.
This causes a memory read that causes the dump thread to crash, resulting in a
failure to generate crash dump. Check fixed to properly detect that this pointer
is greater than actual memory range of current stack.

When LinuxCoreDumper fails to copy process data from a core file, it
fills the return buffer with a repeated sequence of a special marker.
However, MinidumpWriter doesn't know about that and may incorrectly
interpret the data. In many cases, MinidumpWriter simply copies the
gibberish data to the minidump, which isn't too bad. However, the
gibberish data may cause MinidumpWriter to behave badly in some other
cases. For example, when MinidumpWriter tries to iterate through the
linked list of all loaded DSOs via the r_map field of a r_debug struct,
if the linked list is filed with the special marker, the code keeps
iterating through the same address.
This CL addresses the issue by having LinuxCoreDumper::CopyFromProcess()
returns a Boolean value to indicate if the expected data is found from
the core file. MinidumpWriter can then decide how to handle that.
