9498e74 changed the default value of verify_result to an error. This
tripped up NGINX, which depends on a bug[1] in OpenSSL. netty-tcnative
also uses this behavior, though it currently isn't tripped up by 9498e74
because it calls |SSL_set_verify_result|. However, we would like to
remove |SSL_set_verify_result| and with two data points, it seems this
is behavior we must preserve.
This change sets |verify_result| to |X509_V_OK| when a) no client
certificate is requested or b) none is given and it's optional.

If cert_cb runs asynchronously, we end up repeating a large part of very
stateful ClientHello processing. This seems to be mostly fine and there
are few users of server-side cert_cb (it's a new API in 1.0.2), but it's
a little scary.
This is also visible to external consumers because some callbacks get
called multiple times. We especially should try to avoid that as there
is no guarantee that these callbacks are idempotent and give the same
answer each time.

You can provide a per-shim configuration file that includes:

This finishes getting rid of ssl_read_bytes! Now we have separate
entry-points for the various cases. For now, I've kept TLS handshake
consuming records partially. When we do the BIO-less API, I expect that
will need to change, since we won't have the record buffer available.
(Instead, the ssl3_read_handshake_bytes and extend_handshake_buffer pair
will look more like the DTLS side or Go and pull the entire record into
init_buf.)
This change opts to make read_app_data drive the message to completion
in anticipation of DTLS 1.3. That hasn't been specified, but
NewSessionTicket certainly will exist. Knowing that DTLS necessarily has
interleave seems something better suited for the SSL_PROTOCOL_METHOD
internals to drive.
It needs refining, but SSL_PROTOCOL_METHOD is now actually a half-decent
abstraction boundary between the higher-level protocol logic and
DTLS/TLS-specific record-layer and message dispatchy bits.

This is in preparation for switching finish_handshake to a
release_current_message hook. finish_handshake in DTLS is also
responsible for releasing any memory associated with extra messages in
the handshake.
Except that's not right and we need to make it an error anyway. Given
that the rest of the DTLS dispatch layer already strongly assumes there
is only one message in epoch one, putting the check in the fragment
processing works fine enough. Add tests for this.
This will certainly need revising when DTLS 1.3 happens (perhaps just a
version check, perhaps bringing finish_handshake back as a function that
can fail... which means we need a state just before SSL_ST_OK), but DTLS
1.3 post-handshake messages haven't really been written down, so let's
do the easy thing for now and add a test for when it gets more
interesting.
This removes the sequence number reset in the DTLS code. That reset
never did anything becase we don't and never will renego. We should make
sure DTLS 1.3 does not bring the reset back for post-handshake stuff.
(It was wrong in 1.2 too. Penultimate-flight retransmits and renego
requests are ambiguous in DTLS.)

This is the equivalent of FragmentAcrossChangeCipherSuite for DTLS. It
is possible for us to, while receiving pre-CCS handshake messages, to
buffer up a message with sequence number meant for a post-CCS Finished.
When we then get to the new epoch and attempt to read the Finished, we
will process the buffered Finished although it was sent with the wrong
encryption.
Move ssl_set_{read,write}_state to SSL_PROTOCOL_METHOD hooks as this is
a property of the transport. Notably, read_state may fail. In DTLS
check the handshake buffer size. We could place this check in
read_change_cipher_spec, but TLS 1.3 has no ChangeCipherSpec message, so
we will need to implement this at the cipher change point anyway. (For
now, there is only an assert on the TLS side. This will be replaced with
a proper check in TLS 1.3.)

TLS 1.3 will need to call it under different circumstances. We will also
wish to test TLS 1.3 post-handshake auth, so this function must work
without being passed handshake state.
In doing so, implement matching based on signature algorithms as 1.3
does away with the certificate type list.

In TLS 1.3, every extension the server previously sent gets moved to a
separate EncryptedExtensions message. To be able to share code between
the two, parse those extensions separately. For now, the handshake reads
from serverHello.extensions.foo, though later much of the extensions
logic will probably handle serverExtensions independent of whether it
resides in ServerHello or EncryptedExtensions.

TLS 1.3 defines a new SignatureScheme uint16 enum that is backwards
compatible on the wire with TLS1.2's SignatureAndHashAlgorithm. This
change updates the go testing code to use a single signatureAlgorithm
enum (instead of 2 separate signature and hash enums) in preparation for
TLS 1.3. It also unifies all the signing around this new scheme,
effectively backporting the change to TLS 1.2.
For now, it does not distinguish signature algorithms between 1.2 and
1.3 (RSA-PSS instead of RSA-PKCS1, ECDSA must match curve types). When
the C code is ready make a similar change, the Go code will be updated
to match.

This replaces the old key_exchange_info APIs and does not require the
caller be aware of the mess around SSL_SESSION management. They
currently have the same bugs around renegotiation as before, but later
work to fix up SSL_SESSION tracking will fix their internals.
For consistency with the existing functions, I've kept the public API at
'curve' rather than 'group' for now. I think it's probably better to
have only one name with a single explanation in the section header
rather than half and half. (I also wouldn't be surprised if the IETF
ends up renaming 'group' again to 'key exchange' at some point. We'll
see what happens.)

This isn't filled in on the client and Chromium no longer uses it for
plain RSA. It's redundant with existing APIs. This is part of removing
the need for callers to call SSL_get_session where possible.
SSL_get_session is ambiguous when it comes to renego. Some code wants
the current connection state which should not include the pending
handshake and some code wants the handshake scratch space which should.
Renego doesn't exist in TLS 1.3, but TLS 1.3 makes NewSessionTicket a
post-handshake message, so SSL_get_session is somewhat silly of an API
there too.
SSL_SESSION_get_key_exchange_info is a BoringSSL-only API, so we can
freely change it and replace it with APIs keyed on SSL. In doing so, I
think it is better to provide APIs like "SSL_get_dhe_group_size" and
"SSL_get_curve_id" rather than make the caller do the multi-step
SSL_get_current_cipher / SSL_CIPHER_is_ECDHE dance. To that end, RSA
key_exchange_info is pointless as it can already be determined from the
peer certificate.

This is the only codepath where ssl->version can get a garbage value, which is
a little concerning. Since, in all these cases, the peer is failing to connect
and speaks so low a version we don't even accept it anymore, there is probably
not much value in letting them distinguish protocol_version from a record-layer
version number mismatch, where enforced (which will give a version-related
error anyway).
Should we get a decode_error or so just before version negotiation, we'd have
this behavior already.

This was probably the worst offender of them all as read_bytes is the wrong

This API does not work for NEWHOPE, because the client-to-server message

client.
Solve this by introducing a new method which consumes data from the

OpenSSL used to only forbid it on the server in plain PSK and allow it on the

non-anonymous server can optionally request a certificate") and in RFC 4279
("The Certificate and CertificateRequest payloads are omitted from the
response.") is that client auth happens iff we're certificate-based.
The line in RFC 4279 is under the plain PSK section, but that doesn't make a
whole lot of sense and there is only one diagram. PSK already authenticates
both sides. I think the most plausible interpretation is that this is for
certificate-based ciphers.

The DTLS bbio logic is rather problematic, but this shouldn't make things
worse. In the in-handshake case, the new code merges the per-message
(unchecked) BIO_flush calls into one call at the end but otherwise the BIO is
treated as is. Otherwise any behavior around non-block writes should be
preserved.
In the post-handshake case, we now install the buffer when we didn't
previously. On write error, the buffer will have garbage in it, but it will be
discarded, so that will preserve any existing retry behavior. (Arguably the
existing retry behavior is a bug, but that's another matter.)
Add a test for all this, otherwise it is sure to regress. Testing for
