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.

SSL_peek can handle all weird events that SSL_read can, so use runner
and tell bssl_shim to do a SSL_peek + SSL_peek + SSL_read instead of
SSL_read. Then add tests for all the events we may discover.

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.

d2ba8891e0 Improve -valgrind error-handling.
Passing --quiet makes valgrind only print out errors, so we don't need
to suppress things. Combine that with checking valgrind's dedicated exit
code so we notice errors that happen before the "---DONE---" marker.

This makes that marker unnecessary for valgrind. all_tests.go was not
sensitive to this, but still would do well to have valgrind be silent.

7a4aaa4ce7 Fix TLS 1.3 fuzzer mode in Go.
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.

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

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.

9c8c418853 Remove RC4 ciphersuites from TLS.
For now, they can be restored by compiling with -DBORINGSSL_RC4_TLS.

Of note, this means that `MEDIUM' is now empty.

07e7806177 runner: use 3DES instead of RC4 where possible.
To ease the removal of RC4, use 3DES in cases where RC4 is not required,
but is just a placeholder for "ciphersuite that works in SSLv3."

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

e73c7f4281 Flesh out missing TLS 1.3 state machine coverage.
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.
