d7166d07ad Add a standalone ChaCha test.
The coverage tool revealed that we weren't testing all codepaths of the ChaCha
assembly. Add a standalone test as it's much easier to iterate over all lengths
when there isn't the entire AEAD in the way.

I wasn't able to find a really long test vector, so I generated a random one
with the Go implementation we have in runner.

This test gives us full coverage on the ChaCha20_ssse3 variant. (We'll see how
it fares on the other codepaths when the multi-variant test harnesses get in. I
certainly hope there isn't a more novel way to call ChaCha20 than this...)

ab14a4a440 Adding scripts to generate line coverage.
Uses LCOV for C(++) line coverage and Valgrind's Callgrind tool to
generate assembly-level line coverage for the generated assembly
code.

8b9e7802ac Fix up all_tests.go parallelism support.
A len(tests) should have been len(testCases), the code never added to the
sync.WaitGroup, and feeding tests to the tests channel blocks on the tests
completing, so with one worker the results didn't stream. (And if the results
channel wasn't large enough, we'd deadlock.)

f27459e412 Add SPAKE2 over Ed25519.
SPAKE2 is a password-authenticated key exchange. This implementation is
over the twisted Edwards curve Ed25519, and uses SHA-512 as the hash
primitive.

fb2c6f8c85 ASN1_get_object should not accept large universal tags.
The high bits of the type get used for the V_ASN1_NEG bit, so when used with
ASN1_ANY/ASN1_TYPE, universal tags become ambiguous. This allows one to create
a negative zero, which should be impossible. Impose an upper bound on universal
tags accepted by crypto/asn1 and add a test.

6f0c4db90e Enable upstream's Poly1305 code.
The C implementation is still our existing C implementation, but slightly
tweaked to fit with upstream's init/block/emits convention.

I've tested this by looking at code coverage in kcachegrind and

  valgrind --tool=callgrind --dump-instr=yes --collect-jumps=yes

(NB: valgrind 3.11.0 is needed for AVX2. And even that only does 64-bit AVX2,
so we can't get coverage for the 32-bit code yet. But I had to disable that
anyway.)

This was paired with a hacked up version of poly1305_test that would repeat
tests with different ia32cap and armcap values. This isn't checked in, but we
badly need a story for testing all the different variants.

I'm not happy with upstream's code in either the C/asm boundary or how it
dispatches between different versions, but just debugging the code has been a
significant time investment. I'd hoped to extract the SIMD parts and do the
rest in C, but I think we need to focus on testing first (and use that to
guide what modifications would help). For now, this version seems to work at
least.

The x86 (not x86_64) AVX2 code needs to be disabled because it's broken. It
also seems pretty unnecessary.
https://rt.openssl.org/Ticket/Display.html?id=4346

Otherwise it seems to work and buys us a decent performance improvement.
Notably, my Nexus 6P is finally faster at ChaCha20-Poly1305 than my Nexus 4!

35be688078 Enable upstream's ChaCha20 assembly for x86 and ARM (32- and 64-bit).
This removes chacha_vec_arm.S and chacha_vec.c in favor of unifying on
upstream's code. Upstream's is faster and this cuts down on the number of
distinct codepaths. Our old scheme also didn't give vectorized code on
Windows or aarch64.

BoringSSL-specific modifications made to the assembly:

- As usual, the shelling out to $CC is replaced with hardcoding $avx. I've
  tested up to the AVX2 codepath, so enable it all.

- I've removed the AMD XOP code as I have not tested it.

- As usual, the ARM file need the arm_arch.h include tweaked.

Speed numbers follow. We can hope for further wins on these benchmarks after
importing the Poly1305 assembly.

There was a bug in skipPast; it was skipping to the start of the string,
rather than the end of it. But more of an issue is that it would skip if
it was in the middle of the string, which caused problems when
STACK_OF(FOO) was used as a parameter.

At some point, we'll probably need to give this a real C declaration
parser. We still have declarations (like those that return function
pointers) which we can't parse. But for now let's clear the low-hanging
fruit.

34248d4cb7 Get rid of err function codes.
Running make_errors.go every time a function is renamed is incredibly
tedious. Plus we keep getting them wrong.

Instead, sample __func__ (__FUNCTION__ in MSVC) in the OPENSSL_PUT_ERROR macro
and store it alongside file and line number. This doesn't change the format of
ERR_print_errors, however ERR_error_string_n now uses the placeholder
"OPENSSL_internal" rather than an actual function name since that only takes
the uint32_t packed error code as input.

This updates err scripts to not emit the function string table. The
OPENSSL_PUT_ERROR invocations, for now, still include the extra
parameter. That will be removed in a follow-up.

rolled out because “boringssl_lib_sources” has been broken into
“boringssl_crypto_sources” and “boringssl_ssl_sources”.

efad697813 Sync vs_toolschain.py up with Chromium.
win8sdk got renamed to win_sdk. Also minor fixes from upstream, mostly pylint.
Upstream also no longer keeps the toolchain hash in a separate file.

0b635c52b2 Add malloc test support to unit tests.
Currently far from passing and I haven't even tried with a leak checker yet.
Also bn_test is slow.

One of these days we may need to get a more aggressive C parser...

6f2e733bab Add infrastructure for reference counts.
OpenSSL has traditionally done reference counting with |int|s and the
|CRYPTO_add| function. Unless a special callback is installed (rare),
this is implemented by doing the reference count operations under a
lock.

This change adds infrastructure for handling reference counts and uses
atomic operations when C11 support is available.

2607383e72 Fix generate_build_files.py to account for crypto/test.
crypto/test contains not tests, but a test support library that should be
linked into each test.

5c694e3fef Add evp_test, loosely based on upstream's version.
This imports the EVP_PKEY test data of upstream's evptests.txt, but
modified to fit our test framework and with a new test driver. The
remainder of the test data will be imported separately into aead_test
and cipher_test.

Some minor changes to the test format were made to account for test
framework differences. One test has different results since we don't
support RSA signatures with omitted (rather than NULL) parameters.
Otherwise, the biggest difference in test format is that the ad-hoc
result strings are replaced with checking ERR_peek_error.

0f86965ca0 Rename evp_test to evp_extra_test.
This matches how upstream imported that test. evp_test will be used for
the subset of upstream's evp_test which land in our crypto/evp layer.
(Some of crypto/evp is in crypto/cipher for us, so those tests will be
in a ported cipher_test.)
