node.js is, effectively, another bindings library. However, it's better
written than most and, with these changes, only a couple of tiny fixes
are needed in node.js. Some of these changes are a little depressing
however so we'll need to push node.js to use APIs where possible.
Changes:
∙ Support verify_recover. This is very obscure and the motivation
appears to be https://github.com/nodejs/node/issues/477 – where it's
not clear that anyone understands what it means :(
∙ Add a few, no-op #defines
∙ Add some members to |SSL_CTX| and |SSL| – node.js needs to not
reach into these structs in the future.
∙ Add EC_get_builtin_curves.
∙ Add EVP_[CIPHER|MD]_do_all_sorted – these functions are limited to
decrepit.

There is some messiness around saving and restoring the CBB, but this is
still significantly clearer.
Note that the BUF_MEM_grow line is gone in favor of a fixed CBB like the
other functions ported thus far. This line was never necessary as
init_buf is initialized to 16k and none of our key exchanges get that
large. (The largest one can get is DHE_RSA. Even so, it'd take a roughly
30k-bit DH group with a 30k-bit RSA key.)
Having such limits and tight assumptions on init_buf's initial size is
poor (but on par for the old code which usually just blindly assumed the
message would not get too large) and the size of the certificate chain
is much less obviously bounded, so those BUF_MEM_grows can't easily go.
My current plan is convert everything but those which legitimately need
BUF_MEM_grow to CBB, then atomically convert the rest, remove init_buf,
and switch everything to non-fixed CBBs. This will hopefully also
simplify async resumption. In the meantime, having a story for
resumption means the future atomic change is smaller and, more
importantly, relieves some complexity budget in the ServerKeyExchange
code for adding Curve25519.

The function X509_verify_cert checks the value of |ctx->chain| at the
beginning, and if it is NULL then it initialises it, along with the value
of |ctx->untrusted|. The normal way to use X509_verify_cert() is to first
call X509_STORE_CTX_init(); then set up various parameters etc; then call
X509_verify_cert(); then check the results; and finally call
X509_STORE_CTX_cleanup(). The initial call to X509_STORE_CTX_init() sets
|ctx->chain| to NULL. The only place in the OpenSSL codebase where
|ctx->chain| is set to anything other than a non NULL value is in
X509_verify_cert itself. Therefore the only ways that |ctx->chain| could be
non NULL on entry to X509_verify_cert is if one of the following occurs:
1) An application calls X509_verify_cert() twice without re-initialising
in between.
2) An application reaches inside the X509_STORE_CTX structure and changes
the value of |ctx->chain| directly.
With regards to the second of these, we should discount this - it should
not be supported to allow this.
With regards to the first of these, the documentation is not exactly
crystal clear, but the implication is that you must call
X509_STORE_CTX_init() before each call to X509_verify_cert(). If you fail
to do this then, at best, the results would be undefined.
Calling X509_verify_cert() with |ctx->chain| set to a non NULL value is
likely to have unexpected results, and could be dangerous. This commit
changes the behaviour of X509_verify_cert() so that it causes an error if
|ctx->chain| is anything other than NULL (because this indicates that we
have not been initialised properly). It also clarifies the associated
documentation.

We can reuse the HMAC_CTX that stores the key. The API is kind of unfortunate
as, in principle, it should be possible to do an allocation-averse HMAC with a
shared key on multiple threads at once (EVP_AEAD_CTX is normally logically
const). At some point it may be worth rethinking those APIs somewhat. But
these "stateful AEADs" are already stateful in their EVP_CIPHER_CTX, so this is
fine.
Each cipher was run individually to minimize the effect of other ciphers doing
their mallocs. (Although the cost of a malloc is presumably going to depend a
lot on the malloc implementation and what's happened before in the process, so
take these numbers with a bucket of salt. They vary widely even with the same
arguments.)
Taking malloc out of seal/open also helps with the malloc tests. DTLS currently
cannot distinguish a malloc failure (should be fatal) from a decryption failure
(not fatal), so the malloc tests get stuck. But this doesn't completely get us
there since tls_cbc.c mallocs. This also assumes EVP_CIPHER_CTX, EVP_MD_CTX,
and HMAC_CTX are all clever about reusing their allocations when reset (which
they are).

The consumers have all been updated, so we can move EVP_aead_chacha20_poly1305
to its final state. Unfortunately, the _rfc7539-suffixed version will need to
stick around for just a hair longer. Also the tls1.h macros, but the remaining
consumers are okay with that changing underneath them.

https://boringssl-review.googlesource.com/6101 was mismerged from *ring* and
lost some tests. Also add the corresponding tag truncation tests for the new
construction. So long as we have that feature, we should have tests for it.
(Although, do we actually need to support it?)

clang scan-build is annoyed it's not obvious the sizeof line matches the
pointer type. This is easy to fix and makes it be quiet.

Rather than the length of the top-level CBB, which is kind of odd when ASN.1
length prefixes are not yet determined, return the number of bytes written to
the CBB so far. This can be computed without increasing the size of CBB at all.
Have offset and pending_*.
This means functions which take in a CBB as argument will not be sensitive to
whether the CBB is a top-level or child CBB. The extensions logic had to be
careful to only ever compare differences of lengths, which was awkward.
The reversal will also allow for the following pattern in the future, once
CBB_add_space is split into, say, CBB_reserve and CBB_did_write and we add a
CBB_data:
uint8_t *signature;
size_t signature_len = 0;
if (!CBB_add_asn1(out, &cert, CBB_ASN1_SEQUENCE) ||
/* Emit the TBSCertificate. */
!CBB_add_asn1(&cert, &tbs_cert, CBS_ASN1_SEQUENCE) ||
!CBB_add_tbs_cert_stuff(&tbs_cert, stuff) ||
!CBB_flush(&cert) ||
/* Feed it into md_ctx. */
!EVP_DigestSignInit(&md_ctx, NULL, EVP_sha256(), NULL, pkey) ||
!EVP_DigestSignUpdate(&md_ctx, CBB_data(&cert), CBB_len(&cert)) ||
/* Emit the signature algorithm. */
!CBB_add_asn1(&cert, &sig_alg, CBS_ASN1_SEQUENCE) ||
!CBB_add_sigalg_stuff(&sig_alg, other_stuff) ||
/* Emit the signature. */
!EVP_DigestSignFinal(&md_ctx, NULL, &signature_len) ||
!CBB_reserve(&cert, &signature, signature_len) ||
!EVP_DigestSignFinal(&md_ctx, signature, &signature_len) ||
!CBB_did_write(&cert, signature_len)) {
goto err;
}
(Were TBSCertificate not the first field, we'd still have to sample
CBB_len(&cert), but at least that's reasonable straight-forward. The
alternative would be if CBB_data and CBB_len somehow worked on
recently-invalidated CBBs, but that would go wrong once the invalidated CBB's
parent flushed and possibly shifts everything.)
And similar for signing ServerKeyExchange.

Nothing ever uses the return value. It'd be better off discarding it rather
than make callers stick (void) everywhere.

The uint32_t likely dates to them using HASH_LONG everywhere. Nothing ever
touches c->data as a uint32_t, only bytes. (Which makes sense seeing as it
stores the partial block.)

I would hope any sensible compiler would recognize the rotation. (If
not, we should at least pull this into crypto/internal.h.) Confirmed
that clang at least produces the exact same instructions for
sha256_block_data_order for release + NO_ASM. This is also mostly moot
as SHA-1 and SHA-256 both have assembly versions on x86 that sidestep
most of this.
For the digests, take it out of md32_common.h since it doesn't use the
macro. md32_common.h isn't sure whether it's a multiply-included header
or not. It should be, but it has an #include guard (doesn't quite do
what you'd want) and will get HOST_c2l, etc., confused if one tries to
include it twice.
