This avoids having more generated bits. The table is quite small,
especially so when we take out anything we don't implement. There's no
real need to do the binary search. (Exotic things like GOST, the legacy
NID_rsa and NID_dsa_2 spellings of RSA and DSA, and hash functions we
don't implement.)
Mostly this saves me from having to reimplement obj_xref.pl.
(obj_xref.pl processes nid.h, formerly obj_mac.h, so we can't just use
the existing one and still change nid.h.)

Simplify the code, and in particular make |BN_div|, |BN_mod|, and
|BN_nnmod| insensitive to |BN_FLG_CONSTTIME|. This improves the
effectiveness of testing by reducing the number of branches that are
likely to go untested or less tested.
There is no performance-sensitive code that uses BN_div but doesn't
already use BN_FLG_CONSTTIME except RSA signature verification and
EC_GROUP creation. RSA signature verification, ECDH, and ECDSA
performance aren't significantly different with this change.

MSAN doesn't hook |syscall| and thus doesn't know that the kernel has
filled the output buffer when |getrandom| is called.
This change tells MSAN to trust that the memory that |getrandom| writes
to has been initialised. This should avoid false-positives when code
operates on |RAND_bytes| output.

Get one step closer to removing the dependency on |BN_div| from most
programs. Also get one step closer to a constant-time implementation of
|BN_MONT_CTX_set|; we now "just" need to create a constant-time variant
of |BN_mod_lshift1_quick|.
Note that this version might actually increase the side channel signal,
since the variance in timing in |BN_div| is probably less than the variance
from the many conditional reductions in the new method.
On one Windows x64 machine, the speed of RSA verification using the new
version is not too different from the speed of the old code. However,
|BN_div| is generally slow on Windows x64 so I expect this isn't faster
on all platforms. Regardless, we generally consider ECDSA/EdDSA
signature verification performance to be adaquate and RSA signature
verification is much, much faster even with this change.
For RSA signing the performance is not a significant factor since
performance-sensitive applications will cache the |RSA| structure and
the |RSA| structure will cache the Montgomery contexts.

Call |RSA_check_key| after parsing an RSA private key in order to
verify that the key is consistent. This is consistent with ECC key
parsing, which does a similar key check.
Call |RSA_check_key| after key generation mostly as a way of
double-checking the key generation was done correctly. A similar check
was not added to |EC_KEY_generate| because |EC_KEY_generate| is used
for generating ephemeral ECDH keys, and the check would be too
expensive for that use.

This change contains a C implementation of SHA-1 for POWER using
AltiVec. It is almost as fast as the scalar-only assembly implementation
for POWER/POWERPC family in OpenSSL but it is easier to maintain and it
allows error checking with tools like ASAN.
This is tested only for ppc64le. It may nor may not work for other
platforms in the POWER/POWERPC familiy.

obvious fix of marking things as visible causes crashes when built with
ASan (ASan's malloc interceptors and ours are conflicting somehow).

This clears the last of Android's build warnings from BoringSSL. These
pragmas aren't actually no-ops, but it just means that MinGW consumers

There may be something to be said for removing those and having everyone
list dependencies, but I don't really want to chase down every
consumer's build files. Probably not worth the trouble.

This finally removes the last Android hack. Both Chromium and Android
end up needing this thing (Chromium needs it for WebCrypto but currently
uses the EVP_AEAD version and Android needs it by way of
wpa_supplicant).
On the Android side, the alternative is we finish upstream's
NEED_INTERNAL_AES_WRAP patch, but then it just uses its own key-wrap
implementation. This seems a little silly, considering we have a version
of key-wrap under a different API anyway.
It also doesn't make much sense to leave the EVP_AEAD API around if we
don't want people to use it and Chromium's the only consumer. Remove it
and I'll switch Chromium to the new---er, old--- APIs next roll.

If asn1_item_ex_combine_new fails in one of the ASN1_template_new calls
just before the ASN1_OP_NEW_POST call, ASN1_item_ex_free will free the
temporary object which ultimately calls ASN1_OP_FREE_POST. This means
that ASN1_OP_FREE_POST needs to account for zero-initialized objects.

This change adds AES and GHASH assembly from upstream, with the aim of
speeding up AES-GCM.
The PPC64LE assembly matches the interface of the ARMv8 assembly so I've
changed the prefix of both sets of asm functions to be the same
("aes_hw_").
Otherwise, the new assmebly files and Perlasm match exactly those from
upstream's c536b6be1a (from their master branch).

We'd previously been assuming we'd want to predict P-256 and X25519 but,
on reflection, that's nonsense. Although, today, P-256 is widespread and
X25519 is less so, that's not the right question to ask. Those servers
are all 1.2.
The right question is whether we believe enough servers will get to TLS
1.3 before X25519 to justify wasting 64 bytes on all other connections.
Given that OpenSSL has already shipped X25519 and Microsoft was doing
interop testing on X25519 around when we were shipping it, I think the
answer is no.
Moreover, if we are wrong, it will be easier to go from predicting one
group to two rather than the inverse (provided we send a fake one with
GREASE). I anticipate prediction-miss HelloRetryRequest logic across the
TLS/TCP ecosystem will be largely untested (no one wants to pay an RTT),
so taking a group out of the predicted set will likely be a risky
operation.
Only predicting one group also makes things a bit simpler. I haven't
done this here, but we'll be able to fold the 1.2 and 1.3 ecdh_ctx's
together, even.

Really the only thing we should be doing with these ciphers is hastening
their demise, but it was the weekend and this seemed like fun.
EVP_tls_cbc_copy_mac needs to rotate a buffer by a secret amount. (It
extracts the MAC, but rotated.) We have two codepaths for this. If
CBC_MAC_ROTATE_IN_PLACE is defined (always on), we make some assumptions
abuot cache lines, play games with volatile, and hope that doesn't leak
anything. Otherwise, we do O(N^2) work to constant-time select the
rotation incidences.
But we can do O(N lg N). Rotate by powers of two and constant-time
select by the offset's bit positions. (Handwaivy lower-bound: an array
position has N possible values, so, armed with only a constant-time
select, we need O(lg N) work to resolve it. There's N array positions,
so O(N lg N).)
A microbenchmark of EVP_tls_cbc_copy_mac shows this is 27% faster than
the old one, but still 32% slower than the in-place version.
in-place:
Did 15724000 CopyFromMAC operations in 20000744us (786170.8 ops/sec)
N^2:
Did 8443000 CopyFromMAC operations in 20001582us (422116.6 ops/sec)
N lg N:
Did 10718000 CopyFromMAC operations in 20000763us (535879.6 ops/sec)
This results in the following the CBC ciphers. I measured
AES-128-CBC-SHA1 and AES-256-CBC-SHA384 which are, respectively, the
cipher where the other bits are the fastest and the cipher where N is
largest.

TLS CBC performance isn't as important as it was before, and the costs
aren't that high, so avoid making assumptions about cache lines. (If we
care much about CBC open performance, we probably should get the malloc
out of EVP_tls_cbc_digest_record at the end.)

Changing parameters on renegotiation makes all our APIs confusing. This
one has no reason to change, so lock it down. In particular, our
preference to forbid Token Binding + renego may be overridden at the
IETF, even though it's insane. Loosening it will be a bit less of a
headache if EMS can't change.
https://www.ietf.org/mail-archive/web/unbearable/current/msg00690.html
claims that this is already in the specification and enforced by NSS. I
can't find anything to this effect in the specification. It just says
the client MUST disable renegotiation when EMS is missing, which is
wishful thinking. At a glance, NSS doesn't seem to check, though I could
be misunderstanding the code.
Nonetheless, locking this down is a good idea anyway. Accurate or not,
take the email as an implicit endorsement of this from Mozilla.

This and the following commits will import NIST's ECC test vectors.
Right now all our tests pass if I make P-224 act like P-521, which is
kind of embarrassing. (Other curves are actually tested, but only
because runner.go tests them against BoGo.)

We may need to implement high tag number form someday. CBS_get_asn1 has
an unsigned output to allow for this, but CBB_add_asn1 takes a uint8_t
(I think this might be my fault). Fix that which also fixes a
-Wconversion warning.
Simply leaving room in tag representation will still cause troubles
because the class and constructed bits overlap with bits for tag numbers
above 31. Probably the cleanest option would be to shift them to the top
3 bits of a u32 and thus not quite match the DER representation. Then
CBS_get_asn1 and CBB_add_asn1 will internally munge that into the DER
representation and consumers may continue to write things like:
tag_number | CBS_ASN1_CONTEXT_SPECIFIC
I haven't done that here, but in preparation for that, document that
consumers need to use the values and should refrain from assuming the
correspond to DER.

Some, very recent, versions of Clang now support `.arch`. Allow them to
see these directives with BORINGSSL_CLANG_SUPPORTS_DOT_ARCH.

nginx consumes these error codes without #ifdefs. Continue to define

958aaf1ea1, imported from upstream, had an
off-by-one error. Reproducing the failure is fairly easy as it can't
even serialize 1. See also upstream's
099e2968ed3c7d256cda048995626664082b1b30.
Rewrite the function completely with CBB and add a basic test.

I found an earlier reference for an algorithm for the optimized
computation of n0 that is very similar to the one in the "Montgomery
Multiplication" paper cited in the comments. Add a reference to it.
Henry S. Warren, Jr. pointed out that his "Montgomery Multiplication"
paper is not a chapter of his book, but a supplement to the book.
Correct the reference to it.

This was causing some Android breakage. The real bug is actually
entirely in Android for getting its error-handling code wrong and not
handling multiple errors. I'll fix that. (See b/30917411.)
That said, BN_R_NO_INVERSE is a perfectly legitimate reason for those
operations to fail, so ERR_R_INTERNAL_ERROR isn't really a right thing
to push in front anyway. We're usually happy enough with single-error
returns (I'm still a little skeptical of this queue idea), so let's just
leave it at that.

If an oversize BIGNUM is presented to BN_bn2dec() it can cause
BN_div_word() to fail and not reduce the value of 't' resulting
in OOB writes to the bn_data buffer and eventually crashing.
Fix by checking return value of BN_div_word() and checking writes
don't overflow buffer.
Thanks to Shi Lei for reporting this bug.

RT#4530
(Imported from upstream's 7123aa81e9fb19afb11fdf3850662c5f7ff1f19c.)
We've yet to enable this code, but this confirms that we do indeed need
to get our future all-variants stuff working on Windows as well as
Linux and find an AVX2-capable CI setup on each.
The crash here is caused by some win64-only code using %rax as a frame
pointer (perlasm injects a mov rax,rsp in the prologue of every win64
function).
