> Fix signal propagation logic for Linux/Android exception handler.
>
> 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

> 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,

> 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

> 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.

> The fix herein proposed consists in using the si_code (see SI_FROMUSER

> Repro case:
> This issue is visible in Chrome for Android with this simple repro case:

> 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:

Workaround Android sigaction bug

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.

622588226d Fix compatibility with Android NDK r10d. 
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.

be470f3a11 Make breakpad compatible with Android NDK r10d. 
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.

eb81077a4f Microdump writer: stop using new/malloc in compromised context 
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).

19a35ba066 Fix overflow error in breakpad for linux 
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.

d6eb7fa1b8 Handle failures of copying process data from a core file. 
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.

aad5d66fa5 Breakpad: Fix build with new clang versions. 
gcc has a single exception setting for all languages. Saying -fno-exceptions
in gcc disables exceptions and cleanups for cc files, but has no effect for mm
files.

In clang, -fno-exceptions only disables c++ exceptions, but keeps objective-c
exceptions and cleanups enabled.

http://llvm.org/viewvc/llvm-project?view=revision&revision=220714 changed
__EXCEPTIONS to be defined for clang when cleanups are enabled, independent of
if c++ exceptions are enabled. (This was necessary to have clang work with
glibc which looks at __EXCEPTIONS to decide if cleanups are enabled.)

Breakpad tried to use __EXCEPTIONS to figure out if c++ exceptions are enabled.
In cc files, this works: -fno-exceptions will disable c++ exceptions and
cleanups. But in mm files, -fno-exceptions will disable c++ exceptions and
objective-c exceptions will still be enabled, and so cleanups must run and hence
__EXCEPTIONS is defined.

To make things work with both old and new compilers, do the try/catch hack in
mm files either if __EXCEPTIONS is not defined (for old compilers) or if the
compiler is clang and __has_feature(cxx_exceptions) isn't set (which will work
for new clangs too, and which cleanly maps to if c++ exceptions are enabled).

e9df0305d3 dump_syms: Fix handling of DW_FORM_ref_addr to work with DWARF 4 
Previously, dump_syms did not handle DW_FORM_ref_addr if it appeared
in DWARF 4 debugging info.

Also fix a DW_FORM_ref_addr case so that it doesn't fall through to
the next switch case when assertions are disabled and the DWARF
version isn't recognised.

The following steps will reproduce the problem when using LLVM 3.4:

cat <<END >example1.c
int main() { return 0; }
END
cat <<END >example2.c
void foo(int x) {}
END

clang -emit-llvm -g -c example1.c -o example1.bc
clang -emit-llvm -g -c example2.c -o example2.bc
llvm-link-3.4 example1.bc example2.bc -o combined.bc
clang combined.bc -o executable
./google-breakpad/build/src/tools/linux/dump_syms/dump_syms executable

When using LLVM bitcode linking in this way, LLVM's backend generates
partially-merged DWARF debugging info in which some of the references
to the "int" type go via "DW_FORM_ref_addr".  Since PNaCl uses LLVM
bitcode linking, this dump_syms failure occurs with nexes produced by
the PNaCl toolchain.

a4283fc4cf Microdumps: support aarch64 and lib mapping from APK 
- Filter modules by prot flags (only +x) not extensions. It wouldn't
  otherwise catch the case of Chrome mapping the library from the
  apk (which is mapped r-x but doesn't end in .so).
- Use compile-time detection of target arch, in order to cope with
  multilib OSes, where uname() doesn't reflect the run-time arch.
- Add OS information and CPU arch / count.
- Add support for aarch64.
- Add tests and stackwalk expectations for aarch64.
- Fix a potential overflow bug in the processor.
- Rebaseline the tests using smaller symbols.
- Fix microdump_writer_unittest.cc on 32-bit host.

259512f933 Surfacing the process create time in google_breakpad::ProcessState 
and updating minidump_stackwalk to show process uptime.

I tested this with a minidump from Chrome and I got a result that
is inline with what the Windows debugger is showing for that dump:

minidump_stackwalk output:
--------------------------
Process uptime: 601 seconds

WinDBG output:
--------------
Process Uptime: 0 days 0:10:01.000

I didn't update the machine readable output of minidump_stackwalk
on purpose in order to avoid breaking someone that uses it.
It can be added later to the machine output if needed.

725a5dff8a Introduce microdump_stackwalk comand line executable 
This introduces the microdump_stackwalk binary which takes advantage
of the MicrodumpProcessor to symbolize microdumps.
Its operation is identical to the one of minidump_stackwalk.
This CL, in fact, is also refactoring most of the common bits into
stackwalk_common.
