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.

RAND_bytes rarely uses large enough inputs for bsaes to be worth it.
https://boringssl-review.googlesource.com/c/boringssl/+/33589 includes some
rough benchmarks of various bits here. Some observations:
- 8 blocks of bsaes costs roughly 6.5 blocks of vpaes. Note the comparison
isn't quite accurate because I'm measuring bsaes_ctr32_encrypt_blocks against
vpaes_encrypt and vpaes in CTR mode today must make do with a C loop. Even
assuming a cutoff of 6 rather than 7 blocks, it's rare to ask for 96 bytes
of entropy at a time.
- CTR-DRBG performs some stray block operations (ctr_drbg_update), which bsaes
is bad at without extra work to fold them into the CTR loop (not really worth
it).
- CTR-DRBG calculates a couple new key schedules every RAND_bytes call. We
don't currently have a constant-time bsaes key schedule. Unfortunately, even
plain vpaes loses to the current aes_nohw used by bsaes, but it's not
constant-time. Also taking CTR-DRBG out of the bsaes equation
- Machines without AES hardware (clients) are not going to be RNG-bound. It's
mostly servers pushing way too many CBC IVs that care. This means bsaes's
current side channel tradeoffs make even less sense here.
I'm not sure yet what we should do for the rest of the bsaes mess, but it seems
clear that we want to stick with vpaes for the RNG.

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.

OpenSSL's EVP-level EC API involves a separate "paramgen" operation,
which is ultimately just a roundabout way to go from a NID to an
EC_GROUP. But Node uses this, and it's the pattern used within OpenSSL
these days, so this appears to be the official upstream recommendation.
Also add a #define for OPENSSL_EC_EXPLICIT_CURVE, because Node uses it,
but fail attempts to use it. Explicit curve encodings are forbidden by
RFC 5480 and generally a bad idea. (Parsing such keys back into OpenSSL
will cause it to lose the optimized path.)

Our tests are fast, so this does not particularly matter, but SDE
inflates a 13 second test run to 8 minutes. On Windows (MSVC), where we
don't but would like to test with SDE, the difference between optimized

This suggests running SDE tests in release mode. Release mode tests,

This new version makes it much easier to tell which code is handwritten
and which is verified. For some reason, it also is *dramatically* faster
for 32-bit x86 GCC. Clang x86_64, however, does take a small hit.
Benchmarks below.
x86, GCC 7.3.0, OPENSSL_SMALL
(For some reason, GCC used to be really bad at compiling the 32-bit curve25519
code. The new one fixes this. I'm not sure what changed.)

pkg-config gets confused and doesn't know to look in, say,
/usr/lib/i386-linux-gnu when building for 32-bit. Fortunately, CMake
sets a CMAKE_CROSSCOMPILING variable whenever CMAKE_SYSTEM_NAME is set
manually (as done in util/32-bit-toolchain.cmake).

_byteswap_ulong and _byteswap_uint64 are documented (see below link) as coming from stdlib.h.
On some build configurations stdlib.h is pulled in by intrin.h but that is not guaranteed. In particular,
this assumption causes build breaks when building Chromium for Windows ARM64 with clang-cl. This
change switches the #include to use the documented header file, thus fixing Windows ARM64 with clang-cl.

In doing so, update delocate.go so that OPENSSL_ia32cap_get is consistently
callable outside the module. Right now it's callable both inside and outside
normally, but not in FIPS mode because the function is generated. This is
needed for tests and the module to share headers that touch OPENSSL_ia32cap_P.

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.)
