5ecb88b95b Make EnableAllCiphers client-only and rename.
EnableAllCiphers is problematic since some (version, cipher)
combinations aren't even defined and crash. Instead, use the
SendCipherSuite bug to mask the true cipher (which is becomes arbitrary)
for failure tests. The shim should fail long before we get further.

This lets us remove a number of weird checks in the TLS 1.3 code.

This also fixes the UnknownCipher tests which weren't actually testing
anything. EnableAllCiphers is now AdvertiseAllConfiguredCiphers and
does not filter out garbage values.

3c6a1ea674 Apply version/wire mapping at a higher layer in runner.
This is in preparation for implementing the version extension and is
probably what we should have done from the beginning as it makes
intolerance bugs simpler.

This means knobs like SendClientVersion and SendServerVersion deal with
the wire values while knobs like NegotiateVersion and MaxVersion deal
with logical versions. (This matches how the bugs have always worked.
SendFoo is just a weird post-processing bit on the handshake messages
while NegotiateVersion actually changes how BoGo behaves.)

65ac997f20 Implement draft-davidben-tls-grease-01.
This GREASEs cipher suites, groups, and extensions. For now, we'll
always place them in a hard-coded position. We can experiment with more
interesting strategies later.

If we add new ciphers and curves, presumably we prefer them over current
ones, so place GREASE values at the front. This prevents implementations
from parsing only the first value and ignoring the rest.

Add two new extensions, one empty and one non-empty. Place the empty one
in front (IBM WebSphere can't handle trailing empty extensions) and the
non-empty one at the end.

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.

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.

The TLS 1.3 state machine is actually less in need of the aggressive
state machine coverage tests, but nonetheless, we should cover all
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.

0c40a96455 Send unsupported_extension on unexpected ServerHello extensions.
We were sending decode_error, but the spec explicitly says (RFC 5246):

   unsupported_extension
      sent by clients that receive an extended server hello containing
      an extension that they did not put in the corresponding client
      hello.  This message is always fatal.

Also add a test for this when it's a known but unoffered extension. We
actually end up putting these in different codepaths now due to the
custom extensions stuff.

Thanks to Eric Rescorla for pointing this out.

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.)

61672818ef Check for buffered handshake messages on cipher change 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.)

2aad406b1b Switch application traffic keys at the right time in Go TLS 1.3.
The server must switch the outgoing keys early so that client
certificate alerts are sent with the right keys. (Also so that half-RTT
data may be sent.)

Tested by having client and server talk to each other. This adds the
certificate_extensions field to CertificateRequest which I'd previously
missed. (We completely ignore the field, with the expectation that the C
code won't have anything useful to do with it either.)

For now, skip the 1.2 -> 1.1 signal since that will affect shipping
code. We may as well enable it too, but wait until things have settled
down. This implements the version in draft-14 since draft-13's isn't
backwards-compatible.

1fb125c74a Enforce ECDSA curve matching in TLS 1.3.
Implement in both C and Go. To test this, route config into all the
sign.go functions so we can expose bugs to skip the check.

Unfortunately, custom private keys are going to be a little weird since
we can't check their curve type. We may need to muse on what to do here.
Perhaps the key type bit should return an enum that includes the curve?
It's weird because, going forward, hopefully all new key types have
exactly one kind of signature so key type == sig alg == sig alg prefs.
