e1cc35e581 Tolerate cipher changes on TLS 1.3 resumption as a client.
As a client, we must tolerate this to avoid interoperability failures
with allowed server behaviors.

2b02f4b67d Loosen TLS 1.3 session/cipher matching in BoGo.
Draft 18 sadly loosens the requirements to only requiring the PRF hash
stay fixed.

This is generally much cleaner and makes it possible to implement the
more lax cipher matching in draft 18.

71186e85d1 Move ExpectTicketAge out of AcceptAnySession.
It doesn't particular matter, but AcceptAnySession should only skip the
things that would cause us to note accept a ticket. ExpectTicketAge is
an assertion, not part of protocol logic. Accordingly, fix the text.

53210cb48e Do not send unsolicited SCTs in TLS 1.3.
The draft 18 implementation did not compute scts_requested correctly. As
a result, it always believed SCTs were requested. Fix this and add tests
for unsolicited OCSP responses and SCTs at all versions.

Thanks to Daniel Hirche for the report.

75f9914e17 Align TLS 1.2 and 1.3 server session validity checks.
Having that logic in two different places is a nuisance when we go to
add new checks like resumption stuff. Along the way, this adds missing
tests for the ClientHello cipher/session consistency check. (We'll
eventually get it for free once the cipher/resumption change is
unblocked, but get this working in the meantime.)

This also fixes a bug where the session validity checks happened in the
wrong order relative to whether tickets_supported or renew_ticket was
looked at. Fix that by lifting that logic closer to the handshake.

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.

since those may be negotiated via either mechanism. (Those two cases are
actually kinda weird and we may wish to change the spec. But, in the

Also test that we ignore true TLS 1.3's number for now, until we use it,
and that TLS 1.3 suitably ignores ClientHello.version.

This is in preparation for implementing the version extension and is

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.)

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.

2dc0204603 Don't return invalid versions in version_from_wire.
This is in preparation for using the supported_versions extension to
experiment with draft TLS 1.3 versions, since we don't wish to restore
the fallback. With versions begin opaque values, we will want
version_from_wire to reject unknown values, not attempt to preserve
order in some way.

This means ClientHello.version processing needs to be separate code.
That's just written out fully in negotiate_version now. It also means
SSL_set_{min,max}_version will notice invalid inputs which aligns us
better with upstream's versions of those APIs.

This CL doesn't replace ssl->version with an internal-representation
version, though follow work should do it once a couple of changes land
in consumers.

Runner needs to implement fuzzer mode as well so we can record
transcripts from it. A bunch of tests were failing:

- C and Go disagreed on what fuzzer mode did to TLS 1.3 padding. So we
  fuzz more code, align Go with C. Fuzzer mode TLS 1.3 still pads but
  just skips the final AEAD.

- The deterministic RNG should be applied per test, not per exchange. It
  turns out, if your RNG is deterministic, one tends to pick the same
  session ID over and over which confuses clients. (Resumption is
  signaled by echoing the session ID.)

Now the only failing tests are the ones one would expect to fail.

786793411a Do not distinguish NULL and empty PSK identity hints.
Plain PSK omits the ServerKeyExchange when there is no hint and includes
it otherwise (it should have always sent it), while other PSK ciphers
like ECDHE_PSK cannot omit the hint. Having different capabilities here
is odd and RFC 4279 5.2 suggests that all PSK ciphers are capable of
"[not] provid[ing] an identity hint".

Interpret this to mean no identity hint and empty identity hint are the
same state. Annoyingly, this gives a plain PSK implementation two
options for spelling an empty hint. The spec isn't clear and this is not
really a battle worth fighting, so I've left both acceptable and added a
test for this case.

See also https://android-review.googlesource.com/c/275217/. This is also
consistent with Android's PskKeyManager API, our only consumer anyway.

2c66e079ab Don't send the access_denied alert innappropriately.
access_denied is only used to indicate client cert errors and Chrome
maps it to ERR_SSL_BAD_CLIENT_AUTH_CERT accordingly:

   access_denied
      A valid certificate was received, but when access control was
      applied, the sender decided not to proceed with negotiation.  This
      message is always fatal.

We don't appear to be the cause of Chrome's recent
ERR_SSL_BAD_CLIENT_AUTH_CERT spike, but we should send these correctly
nonetheless.

If the early callback fails, handshake_failure seems the most
appropriate ("I was unable to find suitable parameters"). There isn't
really an alert that matches DoS, but internal_error seems okay?

   internal_error
      An internal error unrelated to the peer or the correctness of the
      protocol (such as a memory allocation failure) makes it impossible
      to continue.  This message is always fatal.

There's nothing wrong, per se, with your ClientHello, but I just can't
deal with it right now. Please go away.

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.

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.

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.

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.
