d2242407bb Don't accept signature OIDs in EVP_get_digestby{nid,obj}.
This is a remnant of signature EVP_MDs. Detach them from
EVP_get_digestby{nid,obj}. Nothing appears to rely on this for those two
functions. Alas, Node.js appears to rely on it for EVP_get_digestbyname,
so keep that working.

This avoids causing every consumer's parsing to be unintentionally lax.
It also means fewer OIDs to transcribe when detaching the last of
libcrypto from the legacy ASN.1 stack and its giant OID table.

Note this is an externally visible change. There was one consumer I had
to fix, but otherwise everything handled things incorrectly due to this
quirk, so it seemed better to just fix the API rather than fork off a
second set.

0b8dc30932 Don't use BN_mod_inverse for inverses mod p in RSA keygen.
Instead, use BN_mod_exp_mont_consttime of p - 2. This removes two more
call sites sensitive to BN_FLG_CONSTTIME. We're down to just that last
BN_mod_inverse modulo φ(n). (Sort of. It's actually not sensitive
because even mod inverses always hit the other codepath. Perhaps we
should just leave it alone.)

Note this comes with a slight behavior change. The BN_MONT_CTXs are
initialized a little earlier. If a caller calls RSA_generate_* and then
reaches into the struct to scrap all the fields on it, they'll get
confused. Before, they had to perform an operation on it to get
confused. This is a completely ridiculous thing to do.

Since we do this a lot, this introduces some convenience functions for
doing the Fermat's Little Theorem mod inverse and fixes a leak in the
DSA code should computing kinv hit a malloc error.

14e18ca257 Fix AES-GCM-SIV on large inputs.
This was noticed by observing we had one line of missing test coverage
in polyval.c. CRYPTO_POLYVAL_update_blocks acts 32 blocks at a time and
all existing test vectors are smaller than that.

Test vector obtained by just picking random values and seeing what our
existing implementation did if I modified CRYPTO_POLYVAL_update_blocks
to consume many more blocks at a time. Then I fixed the bug and ensured
the answer was still the same.

ca0642287d Rewrite lhash_test in C++.
Use a std::map as the dummy lhash and use unique_ptr. This also improves
the test to check on pointer equality; we wish to ensure the lhash
stores the particular pointer value we asked for.

dummy_lh now also owns the pointers. It makes things simpler and since
LHASH doesn't free things, we weren't getting anything out of testing
that.

c7df7967fa Don't chain to next_bio for buffer BIO BIO_[w]pending.
Chaining doesn't make much sense. This means we have a discontinuity
when buffer BIOs are empty. For a general filter BIO, this isn't even
meaningful. E.g., the base64 BIO's next_bio doesn't use the same units

(There's one consumer which does call BIO_pending on a base64 BIO, hits
this case, and is only working on accident, I've left it alone for this
CL until we can fix that consumer.)

The DTLS code, notably, assumes BIO_wpending to only report what's in
the buffer BIO. Ideally we'd get rid of the buffer BIO (I'll work on
this next), but, in the meantime, get the sizing right. The immediate
motivation is ssl_test using a BIO pair for DTLS doesn't work.  We've
just been lucky none of the tests have been near the MTU.

The buffer BIO is actually unused outside of the SSL stack, so this
shouldn't break external consumers. But for the base64 BIO consumer
mentioned above, I see nothing else which relies on this BIO_[w]pending
chaining.

720ff53d07 Trim and simplify obj_xref.c.
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.)

9f05de4ebb Remove the non-no_branch branch of BN_div.
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.

16bfff7169 Calculate Montgomery RR without division.
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

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.

4cc1ccd3fc Add minimal tests for 1024-bit RSAZ BN_mod_exp_mont_consttime.
The input base, |a|, isn't reduced mod |m| in the RSAZ case so
incorrect results are given for out-of-range |a| when the RSAZ
implementation is used. On the other hand, the RSAZ implementation is
more correct as far as constant-time operation w.r.t. |a| is concerned.

fa99197b9d perlasm/x86_64-xlate.pl: refine sign extension in ea package.
$1<<32>>32 worked fine with either 32- or 64-bit perl for a good while,
relying on quirk that [pure] 32-bit perl performed it as $1<<0>>0.  But
this apparently changed in some version past minimally required 5.10,
and operation result became 0. Yet, it went unnoticed for another while,
because most perl package providers configure their packages with
-Duse64bitint option.

A recent change to curl[1] added support for HTTPS proxies, which
involves running a TLS connection inside another TLS connection. This
was done by using SSL BIOs, which we removed from BoringSSL for being
crazy.

This change adds a stripped-down version of the SSL BIO to decrepit in

Though it meant a new ring buffer implementation, custom BIOs seem a
better solution for folks who wish to do particularly complicated

were effectively a really confusing and leaky abstraction over a ring
buffer anyway.

df447ba3a9 Add generic AES-GCM-SIV support.
AES-GCM-SIV is an AEAD with nonce-misuse resistance. It can reuse
hardware support for AES-GCM and thus encrypt at ~66% the speed, and
decrypt at 100% the speed, of AES-GCM.

See https://tools.ietf.org/html/draft-irtf-cfrg-gcmsiv-02

This implementation is generic, not optimised, and reuses existing AES
and GHASH support as much as possible. It is guarded by !OPENSSL_SMALL,
at least for now.

14ebb4ff27 Don't compute the Kronecker symbol in ec_GFp_simple_set_compressed_coordinates.
If y is zero, there is no point with odd y, so the odd bit may not be
set, hence EC_R_INVALID_COMPRESSION_BIT. This code instead computed the
Kronecker symbol of x and changed the error code to
EC_R_INVALID_COMPRESSED_POINT if not a square.

As the comment says, this was (intended to be) unreachable. But it
seems x was a typo for tmp1. It dates to before upstream's
6fb60a84dd1ec81953917e0444dab50186617432, when BN_mod_sqrt gave
garbage if its input was not square. Now it emits BN_R_NOT_A_SQUARE.
Upstream's 48fe4d6233ac2d60745742a27f820dd88bc6689d then mapped
BN_R_NOT_A_SQUARE to EC_R_INVALID_COMPRESSED_POINT.

5f04b6bc3a Add ppc64le vector implementation of SHA-1.
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.

Before:

SHA-1 @ 16 bytes: ~30 MB/s
SHA-1 @ 8K: ~140 MB/s

After:

SHA-1 @ 16 bytes: ~70 MB/s
SHA-1 @ 8K: ~480 MB/s

dc16f38685 ec/ecp_nistz256: harmonize is_infinity with ec_GFp_simple_is_at_infinity.
RT#4625

(Imported from upstream's e3057a57caf4274ea1fb074518e4714059dfcabf.)

Add a test in ec_test to cover the ecp_nistz256_points_mul change. Also
revise the low-level infinity tests to cover the changes in
ecp_nistz256_point_add. Upstream's 'infty' logic was also cleaned up to
be simpler and take advantage of the only cases where |p| is infinity.
