This will let us use the same test scenarios for testing messages with
trailing garbage or skipped messages.

5510863fbd Temporary remove the TLS 1.3 anti-downgrade mechanism.
This mechanism is incompatible with deploying draft versions of TLS 1.3.

Suppose a draft M client talks to a draft N server, M != N. (Either M or
N could also be the final standard revision should there be lingering
draft clients or servers.) The server will notice the mismatch and
pretend ClientHello.version is TLS 1.2, not TLS 1.3. But this will
trigger anti-downgrade signal and cause an interop failure! And if it
doesn't trigger, all the clever tricks around ServerHello.random being
signed in TLS 1.2 are moot.

We'll put this back when the dust has settled.

abe94e3b0d Test that SNI warning alerts are ignored.
Although RFC 6066 recommends against it, some servers send a warning
alert prior to ServerHello on SNI mismatch, and, per spec, TLS 1.2
allows it.

We're fine here, but add a test for it. It interacts interestingly with
TLS 1.3 forbidding warning alerts because it happens before version
negotiation.

Add a test that RSA-PSS is available in TLS 1.2 by default, both for
signing and verifying. Note that if a custom SSL_PRIVATE_KEY_METHOD is
used and it sets signing preferences, it won't use RSA-PSS if it doesn't
know about it. (See *-Sign-Negotiate-* tests.)

163c95691a Forbid EMS from changing during renegotation.
Changing parameters on renegotiation makes all our APIs confusing. This
one has no reason to change, so lock it down. In particular, our
preference to forbid Token Binding + renego may be overridden at the
IETF, even though it's insane. Loosening it will be a bit less of a
headache if EMS can't change.

https://www.ietf.org/mail-archive/web/unbearable/current/msg00690.html
claims that this is already in the specification and enforced by NSS. I
can't find anything to this effect in the specification. It just says
the client MUST disable renegotiation when EMS is missing, which is
wishful thinking. At a glance, NSS doesn't seem to check, though I could
be misunderstanding the code.

Nonetheless, locking this down is a good idea anyway. Accurate or not,
take the email as an implicit endorsement of this from Mozilla.

46662482b8 Test resuming renewed sessions.
In TLS 1.3 draft 14, due to resumption using a different cipher, this
is actually not too hard to mess up. (In fact BoGo didn't quite get it
right.)

Fortunately, the new cipher suite negotiation in draft 15 should make
this reasonable again once we implement it. In the meantime, test it.

37646838e9 Have |SSL_get_verify_result| return |X509_V_OK| when no client certificate is given.
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.

[1] See BUGS in https://www.openssl.org/docs/manmaster/ssl/SSL_get_verify_result.html

The TLS 1.3 state machine is actually less in need of the aggressive

handshake shapes. PSK resumption and HelloRetryRequest were missing.

We were also accidentally running "DTLS" versions of the TLS 1.3 tests
but silently running TLS 1.2.

These are probably a good idea to ship so long as we have the PSK

tests otherwise need updating to know about them. We don't care enough
about PSK to be in a rush to ship them, and taking them out is an easier
default action until then.

25fe85b38c Insert a state before cert_cb.
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.

It seems much safer for the default value of |verify_result| to be an
error value.

163f29af07 Move post-handshake message handling out of read_app_data.
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.

4792110b2b Forbid interleaving app data in a HelloRequest.
We already forbid renego/app-data interleave. Forbid it within a
HelloRequest too because that's nonsense. No one would ever send:

   [hs:HelloReq-] [app:Hello world] [hs:-uest]

Add tests for this case.

This is in preparation for our more complex TLS 1.3 post-handshake logic
which is going to go through the usual handshake reassembly logic and,
for sanity, will want to enforce this anyway.

02edcd0098 Reject stray post-Finished messages in DTLS.
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.)

7baf681a8b Convert all of our test private keys to PKCS#8 PEM blobs.
Right now they're RSA PRIVATE KEY or EC PRIVATE KEY which requires a bit
more effort to parse. It means the PEM header is necessary to parse
these. OpenSSL and Go automagically convert the format, but other shims
(namely NSS) may not.
