Unfortunately, due to most OpenSSL assembly using custom exception
handlers to unwind, most of our assembly doesn't work with
non-destructive unwind. For now, CHECK_ABI behaves like
CHECK_ABI_NO_UNWIND on Windows, and CHECK_ABI_SEH will test unwinding on
both platforms.
The tests do, however, work with the unwind-code-based assembly we
recently added, as well as the clmul-based GHASH which is also
code-based. Remove the ad-hoc SEH tests which intentionally hit memory
access exceptions, now that we can test unwind directly.
Now that we can test it, the next step is to implement SEH directives in
perlasm so writing these unwind codes is less of a chore.

Calling conventions must specify how to handle arguments smaller than a
machine word. Should the caller pad them up to a machine word size with
predictable values (zero/sign-extended), or should the callee tolerate
an arbitrary bit pattern?
Annoyingly, I found no text in either SysV or Win64 ABI documentation
describing any of this and resorted to experiment. The short answer is
that callees must tolerate an arbitrary bit pattern on x86_64, which
means we must test this. See the comment in abi_test::internal::ToWord
for the long answer.
CHECK_ABI now, if the type of the parameter is smaller than
crypto_word_t, fills the remaining bytes with 0xaa. This is so the
number is out of bounds for code expecting either zero or sign
extension. (Not that crypto assembly has any business seeing negative
numbers.)
Doing so reveals a bug in ecp_nistz256_ord_sqr_mont. The rep parameter
is typed int, but the code expected uint64_t. In practice, the compiler
will always compile this correctly because:
- On both Win64 and SysV, rep is a register parameter.
- The rep parameter is always a constant, so the compiler has no reason
to leave garbage in the upper half.
However, I was indeed able to get a bug out of GCC via:
uint64_t foo = (1ull << 63) | 2; // Some global the compiler can't
// prove constant.
ecp_nistz256_ord_sqr_mont(res, a, foo >> 1);
Were ecp_nistz256_ord_sqr_mont a true int-taking function, this would
act like ecp_nistz256_ord_sqr_mont(res, a, 1). Instead, it hung. Fix
this by having it take a full-width word.
This mess has several consequences:
- ABI testing now ideally needs a functional testing component to fully cover
this case. A bad input might merely produce the wrong answer. Still,
this is fairly effective as it will cause most code to either segfault
or loop forever. (Not the enc parameter to AES however...)
- We cannot freely change the type of assembly function prototypes. If the
prototype says int or unsigned, it must be ignoring the upper half and
thus "fixing" it to size_t cannot have handled the full range. (Unless
it was simply wrong of the parameter is already bounded.) If the
prototype says size_t, switching to int or unsigned will hit this type
of bug. The former is a safer failure mode though.
- The simplest path out of this mess: new assembly code should *only*
ever take word-sized parameters. This is not a tall order as the bad
parameters are usually ints that should have been size_t.
Calling conventions are hard.

This is much less interesting (stack-based parameters, Windows and SysV
match, no SEH concerns as far as I can tell) than x86_64, but it was
easy to do and I'm more familiar with x86 than ARM, so it made a better
second architecture to make sure all the architecture ifdefs worked out.
Also fix a bug in the x86_64 direction flag code. It was shifting in the
wrong direction, making give 0 or 1<<20 rather than 0 or 1.
(Happily, x86_64 appears to be unique in having vastly different calling
conventions between OSs. x86 is the same between SysV and Windows, and
ARM had the good sense to specify a (mostly) common set of rules.)
Since a lot of the assembly functions use the same names and the tests
were written generically, merely dropping in a trampoline and
CallerState implementation gives us a bunch of ABI tests for free.

Linux and Windows ABIs both require that the direction flag be cleared
on function exit, so that functions can rely on it being cleared on
entry. (Some OpenSSL assembly preserves it, which is stronger, but we
only require what is specified by the ABI so CHECK_ABI works with C
compiler output.)

This uses the x86 trap flag and libunwind to test CFI works at each
instruction. For now, it just uses the system one out of pkg-config and
disables unwind tests if unavailable. We'll probably want to stick a
copy into //third_party and perhaps try the LLVM one later.
This tester caught two bugs in P-256 CFI annotations already:
I47b5f9798b3bcee1748e537b21c173d312a14b42 and
I9f576d868850312d6c14d1386f8fbfa85021b347
An earlier design used PTRACE_SINGLESTEP with libunwind's remote
unwinding features. ptrace is a mess around stop signals (see group-stop
discussion in ptrace(2)) and this is 10x faster, so I went with it. The
question of which is more future-proof is complex:
- There are two libunwinds with the same API,
https://www.nongnu.org/libunwind/ and LLVM's. This currently uses the
system nongnu.org for convenience. In future, LLVM's should be easier
to bundle (less complex build) and appears to even support Windows,
but I haven't tested this. Moreover, setting the trap flag keeps the
test single-process, which is less complex on Windows. That suggests
the trap flag design and switching to LLVM later. However...
- Not all architectures have a trap flag settable by userspace. As far
as I can tell, ARMv8's PSTATE.SS can only be set from the kernel. If
we stick with nongnu.org libunwind, we can use PTRACE_SINGLESTEP and
remote unwinding. Or we implement it for LLVM. Another thought is for
the ptracer to bounce SIGTRAP back into the process, to share the
local unwinding code.
- ARMv7 has no trap flag at all and PTRACE_SINGLESTEP fails. Debuggers
single-step by injecting breakpoints instead. However, ARMv8's trap
flag seems to work in both AArch32 and AArch64 modes, so we may be
able to condition it on a 64-bit kernel.
Sadly, neither strategy works with Intel SDE. Adding flags to cpucap
vectors as we do with ARM would help, but it would not emulate CPUs
newer than the host CPU. For now, I've just had SDE tests disable these.
Annoyingly, CMake does not allow object libraries to have dependencies,
so make test_support a proper static library. Rename the target to
test_support_lib to avoid
https://gitlab.kitware.com/cmake/cmake/issues/17785
Update-Note: This adds a new optional test dependency, but it's disabled
by default (define BORINGSSL_HAVE_LIBUNWIND), so consumers do not need
to do anything. We'll probably want to adjust this in the future.

Unwind testing will make CHECK_ABI much slower. The original
ptrace-based design is some 10,000x slower. I've found an alternate
design that's a mere 1,000x slower, but this probably warrants being
more straightforward. It also removes the weirdness where NDEBUG
controlled which tests were run.
While it does mean we need to write some extra tests for p256-x86_64.pl,
we otherwise do not directly unit test our assembly anyway. Usually we
test the public crypto APIs themselves. So, for most files, this isn't
actually extra work.

Dear reader, I must apologize in advance. This CL contains the following:
- A new 256-line perlasm file with non-trivial perl bits and a dual-ABI
variadic function caller.
- C preprocessor gymnastics, with variadic macros and fun facts about
__VA_ARGS__'s behavior on empty argument lists.
- C++ template gymnastics, including variadic arguments, template
specialization, std::enable_if, and machinery to control template argument
deduction.
Enjoy.
This tests that our assembly functions correctly honor platform ABI
conventions. Right now this only tests callee-saved registers, but it should be
extendable to SEH/CFI unwind testing with single-step debugging APIs.
Register-checking does not involve anything funny and should be compatible with
SDE. (The future unwind testing is unlikely to be compatible.)
This CL adds support for x86_64 SysV and Win64 ABIs. ARM, AArch64, and x86 can
be added in the future. The testing is injected in two places. First, all the
assembly tests in p256-x86_64-test.cc are now instrumented. This is the
intended workflow and should capture all registers.
However, we currently do not unit-test our assembly much directly. We should do
that as follow-up work[0] but, in the meantime, I've also wrapped all of the GTest
main function in an ABI test. This is imperfect as ABI failures may be masked
by other stack frames, but it costs nothing[1] and is pretty reliable at
catching Win64 xmm register failures.
[0] An alternate strategy would be, in debug builds, unconditionally instrument
every assembly call in libcrypto. But the CHECK_ABI macro would be difficult to
replicate in pure C, and unwind testing may be too invasive for this. Still,
something to consider when we C++ libcrypto.
[1] When single-stepped unwind testing exists, it won't cost nothing. The
gtest_main.cc call will turn unwind testing off.

This introduces machinery to start embedding the test data files into
the crypto_test binary. Figuring out every CI's test data story is more
trouble than is worth it. The GTest FileTest runner is considerably
different from the old one:
- It returns void and expects failures to use the GTest EXPECT_* and
ASSERT_* macros, rather than ExpectBytesEqual. This is more monkey
work to convert, but ultimately less work to add new tests. I think
it's also valuable for our FileTest and normal test patterns to align
as much as possible. The line number is emitted via SCOPED_TRACE.
- I've intentionally omitted the Error attribute handling, since that
doesn't work very well with the new callback. This means evp_test.cc
will take a little more work to convert, but this is again to keep our
two test patterns aligned.
- The callback takes a std::function rather than a C-style void pointer.
This means we can go nuts with lambdas. It also places the path first
so clang-format doesn't go nuts.

Chromium's test infrastruction does not actually support GTest. It
requires a custom test runner in //base. Split gtest_main.cc up into a
gtest_main.h which defines a support function we maintain and a default
runner. Chromium's build will swap that file out for a custom one.

We compare pointer/length pairs constantly. To avoid needing to type it
everywhere and get GTest's output, add a StringPiece-alike for byte
slices which supports ==, !=, and std::ostream.
