59b0fccb51 Define BORINGSSL_201510.
I've used these defines to easy the update of BoringSSL in Android
because Android's external/boringssl is a different git repository from
the rest of Android and thus it's not possible to land changes the
atomically update several things at once.

For this I tended just to add this define in the Android copy of
BoringSSL, but we're starting to see that bleed into other situations
now so it's looking like this will be generally useful.

These defines may be added when useful but shouldn't build up: once the
change has been done, the #if'ed code elsewhere that uses it should be
cleaned up. So far, that's worked ok. (I.e. we've had a BORINGSSL_201509
that correctly disappeared.)

38feb990a1 Require that EC points are on the curve.
This removes a sharp corner in the API where |ECDH_compute_key| assumed
that callers were either using ephemeral keys, or else had already
checked that the public key was on the curve.

A public key that's not on the curve can be in a small subgroup and thus
the result can leak information about the private key.

This change causes |EC_POINT_set_affine_coordinates_GFp| to require that
points are on the curve. |EC_POINT_oct2point| already does this.

ac9404c3a8 Improve crypto/digest/md32_common.h mechanism.
The documentation in md32_common.h is now (more) correct with respect
to the most important details of the layout of |HASH_CTX|. The
documentation explaining why sha512.c doesn't use md32_common.h is now
more accurate as well.

Before, the C implementations of HASH_BLOCK_DATA_ORDER took a pointer
to the |HASH_CTX| and the assembly language implementations took a
pointer to the hash state |h| member of |HASH_CTX|. (This worked
because |h| is always the first member of |HASH_CTX|.) Now, the C
implementations take a pointer directly to |h| too.

The definitions of |MD4_CTX|, |MD5_CTX|, and |SHA1_CTX| were changed to
be consistent with |SHA256_CTX| and |SHA512_CTX| in storing the hash
state in an array. This will break source compatibility with any
external code that accesses the hash state directly, but will not
affect binary compatibility.

The second parameter of |HASH_BLOCK_DATA_ORDER| is now of type
|const uint8_t *|; previously it was |void *| and all implementations
had a |uint8_t *data| variable to access it as an array of bytes.

This change paves the way for future refactorings such as automatically
generating the |*_Init| functions and/or sharing one I-U-F
implementation across all digest algorithms.

3fc138eccd Don't bother sampling __func__.
Removing the function codes continued to sample __func__ for compatibility with
ERR_print_errors_cb, but not ERR_error_string_n. We can just emit
OPENSSL_internal for both. ERR_print_errors_cb already has the file and line
number available which is strictly more information than the function name.
(ERR_error_string_n does not, but we'd already turned that to
OPENSSL_internal.)

This shaves 100kb from a release build of the bssl tool.

In doing so, put an unused function code parameter back into ERR_put_error to
align with OpenSSL. We don't need to pass an additional string in anymore, so
OpenSSL compatibility with anything which uses ERR_LIB_USER or
ERR_get_next_error_library costs nothing. (Not that we need it.)

13e81fc971 Fix DTLS asynchronous write handling.
Although the DTLS transport layer logic drops failed writes on the floor, it is
actually set up to work correctly. If an SSL_write fails at the transport,
dropping the buffer is fine. Arguably it works better than in TLS because we
don't have the weird "half-committed to data" behavior. Likewise, the handshake
keeps track of how far its gotten and resumes the message at the right point.

This broke when the buffering logic was rewritten because I didn't understand
what the DTLS code was doing. The one thing that doesn't work as one might
expect is non-fatal write errors during rexmit are not recoverable. The next
timeout must fire before we try again.

This code is quite badly sprinkled in here, so add tests to guard it against
future turbulence. Because of the rexmit issues, the tests need some hacks
around calls which may trigger them. It also changes the Go DTLS implementation
from being completely strict about sequence numbers to only requiring they be
monotonic.

The tests also revealed another bug. This one seems to be upstream's fault, not
mine. The logic to reset the handshake hash on the second ClientHello (in the
HelloVerifyRequest case) was a little overenthusiastic and breaks if the
ClientHello took multiple tries to send.

091c4b9869 Add an option to disable NPN on a per-SSL basis.
Right whether NPN is advertised can only be configured globally on the SSL_CTX.
Rather than adding two pointers to each SSL*, add an options bit to disable it
so we may plumb in a field trial to disable NPN.

Chromium wants to be able to route a bit in to disable NPN, but it uses SSL_CTX
incorrectly and has a global one, so it can't disconnect the callback. (That
really needs to get fixed. Although it's not clear this necessarily wants to be
lifted up to SSL_CTX as far as Chromium's SSLClientSocket is concerned since
NPN doesn't interact with the session cache.)

12f7737d32 Remove BN_MONT_CTX_init.
One less exported function. Nothing ever stack-allocates them, within BoringSSL
or in consumers. This avoids the slightly odd mechanism where BN_MONT_CTX_free
might or might not free the BN_MONT_CTX itself based on a flag.

(This is also consistent with OpenSSL 1.1.x which does away with the _init
variants of both this and BIGNUM so it shouldn't be a compatibility concern
long-term either.)

1269ddd377 Never use the internal session cache for a client.
The internal session cache is keyed on session ID, so this is completely
useless for clients (indeed we never look it up internally). Along the way,
tidy up ssl_update_cache to be more readable. The slight behavior change is
that SSL_CTX_add_session's return code no longer controls the external
callback. It's not clear to me what that could have accomplished. (It can only
fail on allocation error. We only call it for new sessions, so the duplicate
case is impossible.)

The one thing of value the internal cache might have provided is managing the
timeout. The SSL_CTX_flush_sessions logic would flip the not_resumable bit and
cause us not to offer expired sessions (modulo SSL_CTX_flush_sessions's delay
and any discrepancies between the two caches). Instead, just check expiration
when deciding whether or not to offer a session.

This way clients that set SSL_SESS_CACHE_CLIENT blindly don't accidentally
consume gobs of memory.

dc2aea2231 Remove all the logic around custom session IDs and retrying on collisions.
A random 32-byte (so 256-bit) session ID is never going to collide with
an existing one. (And, if it does, SSL_CTX_add_session does account for
this, so the server won't explode. Just attempting to resume some
session will fail.)

That logic didn't completely work anyway as it didn't account for
external session caches or multiple connections picking the same ID in
parallel (generation and insertion happen at different times) or
multiple servers sharing one cache. In theory one could fix this by
passing in a sufficiently clever generate_session_id, but no one does
that.

I found no callers of these functions, so just remove them altogether.

Although Chromium actually uses SSL_(get_)state as part of its fallback
reason heuristic, that function really should go in the deprecated
bucket. I kept SSL_state_string_long since having a human-readable
string is probably useful for logging.

SSL_set_SSL_CTX was only half-documented as the behavior of this
function is very weird. This warrants further investigation and
rethinking.

SSL_set_shutdown is absurd. I added an assert to trip up clearing bits
and set it to a bitwise OR since clearing bits may mess up the state
machine. Otherwise there's enough consumers and it's not quite the same
as SSL_CTX_set_quiet_shutdown that I've left it alone for now.

1d5ef3bb1e Add SSL_set_renegotiate_mode.
Add a slightly richer API. Notably, one can configure ssl_renegotiate_once to
only accept the first renego.

Also, this API doesn't repeat the mistake I made with
SSL_set_reject_peer_renegotiations which is super-confusing with the negation.

df6a3f8b95 Move SSL_CIPHER section just above cipher suite configuration.
Putting it at the top was probably a mistake? Even though SSL_CIPHER
(like SSL_SESSION) doesn't depend on SSL, if you're reading through the
header, SSL_CTX and SSL are the most important types. You could even use
the library without touch cipher suite configs if you don't care since
the default is decently reasonable, though it does include a lot of
ciphers. (Hard to change that if we wanted to because DEFAULT is often
used somewhat like ALL and then people subtract from it.)

32876b3dbb Document cipher suite configuration.
The cipher suite rules could also be anchored on SSL_TXT_* if desired. I
currently documented them in prose largely because SSL_TXT_* also
defines protocol version strings and those are weird; SSL_TXT_TLSV1_1
isn't even a cipher rule. (And, in fact, those are the only SSL_TXT_*
macros that we can't blindly remove. I found some code that #ifdef's the
version SSL_TXT_* macros to decide if version-locked SSL_METHODs are
available.)

Also they clutter the header. I was thinking maybe we should dump a lot
of the random constants into a separate undocumented header or perhaps
just unexport them.

I'm slightly torn on this though and could easily be convinced in the
other direction. (Playing devil's advocate, anchoring on SSL_TXT_* means
we're less likely to forget to document one so long as adding a
SSL_TXT_* macro is the convention.)

97a33939a3 Deprecate basically the entire base64 implementation.
The IUF functions were added for PEM and internally are very lenient to
whitespace and include other PEM-specific behaviors (notably they treat
hyphens as EOF). They also decode a ton of invalid input (see upstream's
RT #3757).

Upstream has a rewrite with tests that resolves the latter issue which
we should review and import. But this is still a very PEM-specific
interface. As this code has basically no callers outside the PEM code
(and any such callers likely don't want a PEM-specific API), it's
probably not worth the trouble to massage this and PEM into a strict IUF
base64 API with PEM whitespace and hyphen bits outside. Just deprecate
it all and leave it in a corner.
