a5f1b38de5 Use vec_vsx_ld to performance unaligned load instead of dereferencing a pointer
and relying on a compiler to generate code for unaligned access.  Both gcc
and llvm currently do that but llvm is going to change to generate code for
aligned access.  The change in llvm will break SHA-1 on POWER without this fix.

e94ec3f85b Use a union in tls_cbc.c.
This is slightly tidier than casting through function pointers. (Also
more defined? But we cast T* => void* within a function pointer all over
the place, so that's probably a lost cause.)

d1c0de6fe0 Add size_t variants of constant-time functions.
These will be used in follow-up commits. The _s names are taken from
upstream, to ease importing code. I've also promoted the CONSTTIME_*
macros from the test. None of them are really necessary except
~0u cannot substitute for CONSTTIME_TRUE_S on 64-bit platforms, so
having the macros seems safer.

Once everything is converted, I expect the unsigned versions can be
removed, so I've made the _8 and _int functions act on size_t rather
than unsigned. The users of these functions basically only believe that
array indices and bytes exist.

764ab9802e Support and test P-224 certificates.
Previously we only needed to be able to serve P-224 certificates, but
now we anticipate a need to be able to connect and validate them also.
Since this requires advertising support for P-224 in the handshake, we
need to support P-224 ECDHE too.

P-224 support is disabled by default and so clients need to both set the
enabled curves explicitly and set a maximum version of TLS 1.2.

0f5d7d3f04 Just allocate what's needed for SSL write buffers.
When we refactored all the buffering logic, we retained upstream
OpenSSL's allocation patterns. In particular, we always allocated fixed
size write buffer, even though, unlike when reading, we trivially know a
tighter bound (namely however much we happen to be writing right now).

Since the cutoff for when Windows' malloc starts having a hard time is
just below the TLS maximum record size, do the more natural thing of
allocating what we need to hold outgoing ciphertext.

(This only does anything to the write half. Read half is a bit more
involved.)

2a0707210a Prevent Channel ID and Custom Extensions on 0-RTT.
Channel ID is incompatible with 0-RTT, so we gracefully decline 0-RTT
as a server and forbid their combination as a client. We'll keep this
logic around until Channel ID is removed.

Channel ID will be replaced by tokbind which currently uses custom
extensions. Those will need additional logic to work with 0-RTT.
This is not implemented yet so, for now, fail if both are ever
configured together at all. A later change will allow the two to
combine.

794cc59e25 Send half-RTT tickets when negotiating 0-RTT.
Once 0-RTT data is added to the current 0-RTT logic, the server will
trigger a write when processing incoming data via SSL_read. This means
SSL_read will block on transport write, which is something we've not
tried to avoid far (assuming no renegotiation).

The specification allows for tickets to be sent at half-RTT by
predicting the client Finished. By doing this we both get the tickets on
the wire sooner and avoid confusing I/O patterns. Moreover, we
anticipate we will need this mode for one of the QUIC stateless reject
patterns.

This is tested by always processing NewSessionTickets in the
ExpectHalfRTTData path on 0-RTT connections. As not other
implementations using BoGo may not do this, this is configurable via the
shim config.

02084ea398 Decouple PKCS8_encrypt and PKCS8_decrypt's core from crypto/asn1.
These will be used by Chromium's crypto::ECPrivateKey to work with
EncryptedPrivateKeyInfo structures.

Note this comes with a behavior change: PKCS8_encrypt and PKCS8_decrypt
will no longer preserve PKCS#8 PrivateKeyInfo attributes. However, those
functions are only called by Chromium which does not care. They are also
called by the PEM code, but not in a way which exposes attributes.

The PKCS#12 PFX code is made to use PKCS8_parse_encrypted_private_key
because it's cleaner (no more tossing X509_SIG around) and to ease
decoupling that in the future.

crypto/pkcs8's dependency on the legacy ASN.1 stack is now limited to
pkcs8_x509.c.

3cb12467cc Remove session_tickets_sent.
This is a remnant of before we made the handshake write
flight by flight.

7ce10d5da7 Partially split out crypto/pkcs8's legacy ASN.1 dependencies.
PKCS8_encrypt and PKCS8_decrypt still need to be split. The code for
processing PKCS#12 files is, for now, placed entirely in pkcs8_x509.c.
If we need to split it up, it should be straightforward to do so.
(Introduce a CRYPTO_BUFFER version of PKCS12_get_key_and_certs and go
from there.)

e3843d41b9 Run all state machine coverage tests on implicit handshake.
The tests all work fine under it except for tests where the shim shuts
down. (In those the shim calls SSL_shutdown as the first function, so it
wouldn't do anything useful.)

f466cdb5e0 size_t the RSA padding add functions.
The padding check functions will need to tweak their calling conventions
and the constant-time helpers, so leaving those alone for now. These
were the easy ones.

8cd7bbf514 Push password encoding back into pkcs12_key_gen.
With PKCS8_encrypt_pbe and PKCS8_decrypt_pbe gone in
3e8b782c0c, we can restore the old
arrangement where the password encoding was handled in pkcs12_key_gen.
This simplifies the interface for the follow-up crypto/asn1 split.

Note this change is *not* a no-op for PKCS#12 files which use PBES2.
Before, we would perform the PKCS#12 password encoding for all parts of
PKCS#12 processing. The new behavior is we only perform it for the parts
that go through the PKCS#12 KDF. For such a file, it would only be the
MAC.

I believe the specification supports our new behavior. Although RFC 7292
B.1 says something which implies that the transformation is about
converting passwords to byte strings and would thus be universal,
appendix B itself is prefaced with:

   Note that this method for password privacy mode is not recommended
   and is deprecated for new usage.  The procedures and algorithms
   defined in PKCS #5 v2.1 [13] [22] should be used instead.
   Specifically, PBES2 should be used as encryption scheme, with PBKDF2
   as the key derivation function.

"This method" refers to the key derivation and not the password
formatting, but it does give support to the theory that password
formatting is tied to PKCS#12 key derivation.

(Of course, if one believes PKCS#12's assertion that their inane
encoding (NUL-terminated UTF-16!) is because PKCS#5 failed to talk about
passwords as Unicode strings, one would think that PBES2 (also in
PKCS#5) would have the same issue and thus need PKCS#12 to valiantly
save the day with an encoding...)

This matches OpenSSL's behavior and that of recent versions of NSS. See
https://bugzilla.mozilla.org/show_bug.cgi?id=1268141. I was unable to
figure out what variants, if any, macOS accepts.

3cb047e56c Decouple PKCS#12 hash lookup from the OID table.
This isn't strictly necessary for Chromium yet, but we already have a
decoupled version of hash algorithm parsing available. For now, don't
export it but eventually we may wish to use it for OCSP.

This adds support on the server and client to accept data-less early
data. The server will still fail to parse early data with any
contents, so this should remain disabled.

f35e8384a8 Fix parsing of PBKDF2 parameters.
The OPTIONAL prf field is an AlgorithmIdentifier, not an OID.  I messed
this up in the recent rewrite.

Fix the parsing and add a test, produced by commenting out the logic in
OpenSSL to omit the field for hmacWithSHA1. (We don't currently support
any other PBKDF2, or I'd just add a test for that.)
