a5ee83f67e Test different chunk sizes in cipher_test.
This change causes cipher_test to test the EVP cipher interfaces with
various chunk sizes and adds a couple of large tests of GCM. This is
sufficient to uncover the issue that would have been caused by a3d9528e,
had the AVX code been enabled.

b9824e2417 Handle SSL_shutdown while in init more appropriately
Calling SSL_shutdown while in init previously gave a "1" response,
meaning everything was successfully closed down (even though it
wasn't). Better is to send our close_notify, but fail when trying to
receive one.

The problem with doing a shutdown while in the middle of a handshake
is that once our close_notify is sent we shouldn't really do anything
else (including process handshake/CCS messages) until we've received a
close_notify back from the peer. However the peer might send a CCS
before acting on our close_notify - so we won't be able to read it
because we're not acting on CCS messages!

85003903fc Remove CRYPTO_set_NEON_functional.
This depends on https://codereview.chromium.org/1730823002/. The bit was only
ever targetted to one (rather old) CPU. Disable NEON on it uniformly, so we
don't have to worry about whether any new NEON code breaks it.

a3d9528e9e Unify AEAD and EVP code paths for AES-GCM.
This change makes the AEAD and EVP code paths use the same code for
AES-GCM. When AVX instructions are enabled in the assembly this will
allow them to use the stitched AES-GCM implementation.

Note that the stitched implementations are no-ops for small inputs
(smaller than 288 bytes for encryption; smaller than 96 bytes for
decryption). This means that only a handful of test cases with longish
inputs actually test the stitched code.

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.

f4ef9b517e otherPrimeInfos is not optional in version 1 RSAPrivateKeys.
Currently, we correctly refuse to parse version 0 multi-prime keys, but we
still parse version 1 two-prime keys. Both should be rejected.

I missed an additional clause in the spec originally. It seems otherPrimeInfos
is marked OPTIONAL not because it is actually optional, but because they wanted
the two RSAPrivateKey forms to share one definition. The prose rules following
the definition imply that otherPrimeInfos' presence is entirely determined by
the version:

    * version is the version number, for compatibility with future
      revisions of this document.  It shall be 0 for this version of the
      document, unless multi-prime is used, in which case it shall be 1.

            Version ::= INTEGER { two-prime(0), multi(1) }
               (CONSTRAINED BY
               {-- version must be multi if otherPrimeInfos present --})

and:

    * otherPrimeInfos contains the information for the additional primes
      r_3, ..., r_u, in order.  It shall be omitted if version is 0 and
      shall contain at least one instance of OtherPrimeInfo if version
      is 1.

e30a09e604 Implement new PKCS#8 parsers.
As with SPKI parsers, the intent is make EVP_PKEY capture the key's
constraints in full fidelity, so we'd have to add new types or store the
information in the underlying key object if people introduce variant key
types with weird constraints on them.

Note that because PKCS#8 has a space for arbitrary attributes, this
parser must admit a hole. I'm assuming for now that we don't need an API
that enforces no attributes and just ignore trailing data in the
structure for simplicity.

Previously, OpenSSL supported many different DSA PKCS#8 encodings. Only
support the standard format. One of the workaround formats (SEQUENCE of
private key and public key) seems to be a workaround for an old Netscape

239a0abfd5 Slightly simplify and deprecate i2d_{Public,Private}Key.
There are all the type-specific serializations rather than something
tagged with a type. i2d_PrivateKey's PKCS#8 codepath was unreachable
because every EVP_PKEY type has an old_priv_encode function.

To prune EVP_PKEY_ASN1_METHOD further, replace i2d_PrivateKey into a
switch case so we don't need to keep old_priv_encode around. This cuts
down on a case of outside modules reaching into crypto/evp method
tables.

68772b31b0 Implement new SPKI parsers.
Many consumers need SPKI support (X.509, TLS, QUIC, WebCrypto), each
with different ways to set signature parameters. SPKIs themselves can
get complex with id-RSASSA-PSS keys which come with various constraints
in the key parameters. This suggests we want a common in-library
representation of an SPKI.

This adds two new functions EVP_parse_public_key and
EVP_marshal_public_key which converts EVP_PKEY to and from SPKI and
implements X509_PUBKEY functions with them. EVP_PKEY seems to have been
intended to be able to express the supported SPKI types with
full-fidelity, so these APIs will continue this.

This means future support for id-RSASSA-PSS would *not* repurpose
EVP_PKEY_RSA. I'm worried about code assuming EVP_PKEY_RSA implies
acting on the RSA* is legal. Instead, it'd add an EVP_PKEY_RSA_PSS and
the data pointer would be some (exposed, so the caller may still check
key size, etc.) RSA_PSS_KEY struct. Internally, the EVP_PKEY_CTX
implementation would enforce the key constraints. If RSA_PSS_KEY would
later need its own API, that code would move there, but that seems
unlikely.

Ideally we'd have a 1:1 correspondence with key OID, although we may
have to fudge things if mistakes happen in standardization. (Whether or
not X.509 reuses id-ecPublicKey for Ed25519, we'll give it a separate
EVP_PKEY type.)

DSA parsing hooks are still implemented, missing parameters and all for
now. This isn't any worse than before.

Decoupling from the giant crypto/obj OID table will be a later task.

3cadf63c68 Remove DSA write_params.
This imports upstream's ea6b07b54c1f8fc2275a121cdda071e2df7bd6c1 along
with a bugfix in 987157f6f63fa70dbeffca3c8bc62f26e9767ff2.

In an SPKI, a DSA key is only an INTEGER, with the group information in
the AlgorithmIdentifier. But a standalone DSAPublicKey is more complex
(and apparently made up by OpenSSL). OpenSSL implemented this with a
write_params boolean and making DSAPublicKey a CHOICE.

Instead, have p_dsa_asn1.c encode an INTEGER directly. d2i_DSAPublicKey
only parses the standalone form. (That code will be replaced later, but
first do this in preparation for rewriting the DSA ASN.1 code.)

2f6410ba4e Rewrite ECPrivateKey serialization.
Functions which lose object reuse and need auditing:
- d2i_ECParameters
- d2i_ECPrivateKey

This adds a handful of bytestring-based APIs to handle EC key
serialization. Deprecate all the old serialization APIs. Notes:

- An EC_KEY has additional state that controls its encoding, enc_flags
  and conv_form. conv_form is left alone, but enc_flags in the new API
  is an explicit parameter.

- d2i_ECPrivateKey interpreted its T** argument unlike nearly every
  other d2i function. This is an explicit EC_GROUP parameter in the new
  function.

- The new specified curve code is much stricter and should parse enough
  to uniquely identify the curve.

- I've not bothered with a new version of i2d_ECParameters. It just
  writes an OID. This may change later when decoupling from the giant
  OID table.

- Likewise, I've not bothered with new APIs for the public key since the
  EC_POINT APIs should suffice.

- Previously, d2i_ECPrivateKey would not call EC_KEY_check_key and it
  was possible for the imported public and private key to mismatch. It
  now calls it.

666973b8e9 Add tests for EC keys with specified curves.
In c0d9484902, we had to add support for
recognizing specified versions of named curves. I believe the motivation
was an ECPrivateKey encoded by OpenSSL without the EC_KEY's asn1_flag
set to OPENSSL_EC_NAMED_CURVE. Annoyingly, it appears OpenSSL's API
defaulted to the specified form while the tool defaulted to the named
form.

Add tests for this at the ECPrivateKey and the PKCS#8 level. The latter
was taken from Chromium's ec_private_key_unittest.cc which was the
original impetus for this.

375124b162 Parse BER for PKCS#12 more accurately.
CBS_asn1_ber_to_der currently uses heuristics because implicitly-tagged
constructed strings in BER are ambiguous with implicitly-tagged sequences. It's
not possible to convert BER to DER without knowing the schema.

Fortunately, implicitly tagged strings don't appear often so instead split the
job up: CBS_asn1_ber_to_der fixes indefinite-length elements and constructed
strings it can see. Implicitly-tagged strings it leaves uncoverted, but they
will only nest one level down (because BER kindly allows one to nest
constructed strings arbitrarily!).

CBS_get_asn1_implicit_string then performs the final concatenation at parse
time. This isn't much more complex and lets us parse BER more accurately and
also reject a number of mis-encoded values (e.g. constructed INTEGERs are not a
thing) we'd previously let through. The downside is the post-conversion parsing
code must be aware of this limitation of CBS_asn1_ber_to_der. Fortunately,
there's only one implicitly-tagged string in our PKCS#12 code.

(In the category of things that really really don't matter, but I had spare
cycles and the old BER converter is weird.)

47ebec1210 Validate DH public keys for RFC 5114 groups.
This is CVE-2016-0701 for OpenSSL, reported by Antonio Sanso. It is a no-op for
us as we'd long removed SSL_OP_DH_SINGLE_USE and static DH cipher suites. (We
also do not parse or generate X9.42 DH parameters.)

However, we do still have the APIs which return RFC 5114 groups, so we should
perform the necessary checks in case later consumers reuse keys.

Unlike groups we generate, RFC 5114 groups do not use "safe primes" and have
many small subgroups. In those cases, the subprime q is available. Before using
a public key, ensure its order is q by checking y^q = 1 (mod p). (q is assumed
to be prime and the existing range checks ensure y is not 1.)

0a2c9938a5 Don't allow the specifiedCurve form of ECParameters in SPKIs.
Although RFC 3279 allows both, per RFC 5912, keys must use a named curve
rather than spelling out the curve parameters. Although we do not allow
arbitrary curves, we do have to (pretty hackishly) recognize built-in
curves in ECPrivateKeys.

It seems the cause of this was that OpenSSL, unless you set asn1_flag on
the EC_GROUP, likes to encode keys by spelling out the parameters. This
is in violation of RFC 5915, though probably not in violation of one of
the other redundant ECC specifications. For more fun, it appears
asn1_flag defaults to *off* in the API and *on* in the command-line
tools.

I think the original cause was these defaults meant the pre-BoringSSL
Android/OpenSSL Chromium port wrote out Channel ID keys in this format.
By now this should no longer by an issue, but it'll warrant a bit more
investigation to be sure we can drop it.

For now, keep this logic out of SPKIs by not calling d2i_ECParameters.
d2i_ECParameters is a fairly pointless function when only named curves
are allowed. In testing other implementations, none of Firefox, Safari,
or IE11/Win will parse such certificates (i.e. the error is fatal and
unbypassable). Likewise, because Mac and Windows' underlying libraries
reject this, Chrome on Mac and Windows already rejects such things. Thus
this change should be compatible.

The following is the certificate and key I constructed to test with:

f6094e05ef Don't allow EVP_PKEY_RSA2.
OpenSSL accepts both OID 2.5.8.1.1 and OID 1.2.840.113549.1.1.1 for RSA
public keys. The latter comes from RFC 3279 and is widely implemented.
The former comes from the ITU-T version of X.509. Interestingly,
2.5.8.1.1 actually has a parameter, which OpenSSL ignores:

  rsa ALGORITHM ::= {
     KeySize
     IDENTIFIED BY id-ea-rsa
  }
  KeySize ::= INTEGER

Remove support for 2.5.8.1.1 completely. In tests with a self-signed
certificate and code inspection:

- IE11 on Win8 does not accept the certificate in a TLS handshake at
  all. Such a certificate is fatal and unbypassable. However Microsoft's
  libraries do seem to parse it, so Chrome on Windows allows one to
  click through the error. I'm guessing either the X.509 stack accepts
  it while the TLS stack doesn't recognize it as RSA or the X.509 stack
  is able to lightly parse it but not actually understand the key. (The
  system certificate UI didn't display it as an RSA key, so probably the
  latter?)

- Apple's certificate library on 10.11.2 does not parse the certificate
  at all. Both Safari and Chrome on Mac treat it as a fatal and
  unbypassable error.

- mozilla::pkix, from code inspection, does not accept such
  certificates. However, Firefox does allow clicking through the error.
  This is likely a consequence of mozilla::pkix and NSS having different
  ASN.1 stacks. I did not test this, but I expect this means Chrome on
  Linux also accepts it.

Given IE and Safari's results, it should be safe to simply remove this.
Firefox's data point is weak (perhaps someone is relying on being able
to click-through a self-signed 2.5.8.1.1 certificate), but it does
further ensure no valid certificate could be doing this.

The following is the 2.5.8.1.1 certificate I constructed to test with.
The private key is key.pem from ssl/test/runner:

719594e512 Un-const EVP_PKEY_CTX_set0_rsa_oaep_label and fix overflow check.
It takes ownership of the buffer, so it's not actually const. The
const-ness gets dropped once it transits through EVP_PKEY_CTX_ctrl.

Also compare against INT_MAX explicitly for the overflow check. I'm not sure
whether the casting version is undefined, but comparing against INT_MAX matches
the rest of the codebase when transiting in and out of signed ints.

EVP_PKEY_CTX has no way for callers to register callbacks, which means
there shouldn't be a way for the library to present you an EVP_PKEY_CTX
out-of-context. (Whereas app_data/ex_data makes sense on SSL because of
its numerous callbacks or RSA because of RSA_METHOD.)

f5f4be8fac Fix pointer-to-non-volatile cast in thread_win.c.
Casting a pointer-to-non-volatile to pointer-to-volatile can be a no-op
as the compiler only requires volatile semantics when the pointed-to
object is a volatile object and there are no pointers-to-non-volatile
involved. This probably doesn't matter unless building with the MSVC
-volatile:iso flag, and maybe not even then, but it is good practice
anyway.

54a8d7c14f Use Barrett reduction in CBC processing rather than tricks.
Division isn't constant-time on Intel chips so the code was adding a
large multiple of md_size to try and force the operation to always take
the maximum amount of time.

I'm less convinced, these days, that compilers aren't going to get smart
enough to optimise that away so use Barrett reduction instead.

ce9d85eedd Tweaks for node.js
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.

With these stubs, cURL should not need any BoringSSL #ifdefs at all,
except for their OCSP #ifdefs (which can switch to the more generally
useful OPENSSL_NO_OCSP) and the workaround for wincrypt.h macro
collisions. That we intentionally leave to the consumer rather than add
a partial hack that makes the build sensitive to include order.

(I'll send them a patch upstream once this cycles in.)

62882187c9 Update comments to better document in-place semantics.
(Comment-only change; no functional difference.)

Some code was broken by the |d2i_ECDSA_SIG| change in 87897a8c. It was
passing in a pointer to an existing |ECDSA_SIG| as the first argument
and then simply assuming that the structure would be updated in place.
The comments on the function suggested that this was reasonable.

This change updates the comments that use similar wording to either note
that the function will never update in-place, or else to note that
depending on that is a bad idea for the future.

I've also audited all the uses of these functions that I can find and,
in addition to the one case with |d2i_ECDSA_SIG|, there are several
users of |d2i_PrivateKey| that could become a problem in the future.
I'll try to fix them before it does become an issue.
