d9cbb53562 Fix SSL_version on 0-RTT.
Like other handshake properties, when in 0-RTT on the client,
SSL_version should report the predicted version. This used to work on
accident because of how ssl->version got set in handshake_client.c early
(and that TLS 1.4 does not exist), but we no longer do that.

a1ce85696d Test record splitting at all ciphers.
We were missing AES256 and 3DES. Though this test dates to the old
record-splitting code which was much scarier than the new one.

19670949ca Align EVP_PKEY Ed25519 API with upstream.
Rather than adding a new mode to EVP_PKEY_CTX, upstream chose to tie
single-shot signing to EVP_MD_CTX, adding functions which combine
EVP_Digest*Update and EVP_Digest*Final. This adds a weird vestigial
EVP_MD_CTX and makes the signing digest parameter non-uniform, slightly
complicating things. But it means APIs like X509_sign_ctx can work
without modification.

Align with upstream's APIs. This required a bit of fiddling around
evp_test.cc. For consistency and to avoid baking details of parameter
input order, I made it eagerly read all inputs before calling
SetupContext. Otherwise which attributes are present depend a lot on the
shape of the API we use---notably the NO_DEFAULT_DIGEST tests for RSA
switch to failing before consuming an input, which is odd.

(This only matters because we have some tests which expect the operation
to abort the operation early with parameter errors and match against
Error. Those probably should not use FileTest to begin with, but I'll
tease that apart a later time.)

Upstream also named NID_Ed25519 as NID_ED25519, even though the
algorithm is normally stylized as "Ed25519". Switch it to match.

3cfeb9522b Disable SSLv3 by default.
As a precursor to removing the code entirely later, disable the protocol
by default. Callers must use SSL_CTX_set_min_version to enable it.

This change also makes SSLv3_method *not* enable SSL 3.0. Normally
version-specific methods set the minimum and maximum version to their
version. SSLv3_method leaves the minimum at the default, so we will
treat it as all versions disabled. To help debugging, the error code is
switched from WRONG_SSL_VERSION to a new NO_SUPPORTED_VERSIONS_ENABLED.

This also defines OPENSSL_NO_SSL3 and OPENSSL_NO_SSL3_METHOD to kick in
any no-ssl3 build paths in consumers which should provide a convenient
hook for any upstreaming changes that may be needed. (OPENSSL_NO_SSL3
existed in older versions of OpenSSL, so in principle one may encounter
an OpenSSL with the same settings.)

This only works at TLS 1.2 and above as, before TLS 1.2, there is no way
to advertise support for Ed25519 or negotiate the correct signature
algorithm. Add tests for this accordingly.

For now, this is disabled by default on the verifying side but may be
enabled per SSL_CTX. Notably, projects like Chromium which use an
external verifier may need changes elsewhere before they can enable it.
(On the signing side, we can assume that if the caller gave us an
Ed25519 certificate, they mean for us to use it.)

764ab9802e Support and test P-224 certificates.
Previously we only needed to be able to serve P-224 certificates, but
now we anticipate a need to be able to connect and validate them also.
Since this requires advertising support for P-224 in the handshake, we
need to support P-224 ECDHE too.

P-224 support is disabled by default and so clients need to both set the
enabled curves explicitly and set a maximum version of TLS 1.2.

2a0707210a Prevent Channel ID and Custom Extensions on 0-RTT.
Channel ID is incompatible with 0-RTT, so we gracefully decline 0-RTT
as a server and forbid their combination as a client. We'll keep this
logic around until Channel ID is removed.

Channel ID will be replaced by tokbind which currently uses custom
extensions. Those will need additional logic to work with 0-RTT.
This is not implemented yet so, for now, fail if both are ever
configured together at all. A later change will allow the two to
combine.

794cc59e25 Send half-RTT tickets when negotiating 0-RTT.
Once 0-RTT data is added to the current 0-RTT logic, the server will
trigger a write when processing incoming data via SSL_read. This means
SSL_read will block on transport write, which is something we've not
tried to avoid far (assuming no renegotiation).

The specification allows for tickets to be sent at half-RTT by
predicting the client Finished. By doing this we both get the tickets on
the wire sooner and avoid confusing I/O patterns. Moreover, we
anticipate we will need this mode for one of the QUIC stateless reject
patterns.

This is tested by always processing NewSessionTickets in the
ExpectHalfRTTData path on 0-RTT connections. As not other
implementations using BoGo may not do this, this is configurable via the
shim config.

The |select_certificate_cb| return values are somewhat confusing due
to the fact that they don't match the |cert_cb| ones, despite the
similarities between the two callbacks (they both have "certificate" in
the name! well, sort of).

This also documents the error return value (-1) which was previously
undocumented, and it expands the |SSL_CTX_set_select_certificate_cb|
documentation regarding retrial (by shamelessly copying from
|SSL_CTX_set_ticket_aead_method|).

Also updates other scattered documentation that was missed by previous
changes.

11c82895d7 Remove support for blocking DTLS timeout handling.
The DTLS stack has two very different APIs for handling timeouts. In
non-blocking mode, timeouts are driven externally by the caller with
DTLSv1_get_timeout. In blocking mode, timeouts are driven by the BIO by
calling a BIO_ctrl with BIO_CTRL_DGRAM_SET_NEXT_TIMEOUT.

The latter is never used by consumers, so remove support for it.
BIO_CTRL_DGRAM_SET_NEXT_TIMEOUT implicitly depends on struct timeval
being used for timestamps, which we would like to remove. Without this,
the only public API which relies on this is the testing-only
SSL_CTX_set_current_time_cb which is BoringSSL-only and we can change at
our leisure.

a57dcfb69c Add new cipherlist-setting APIs that reject nonsense.
The new APIs are SSL_CTX_set_strict_cipher_list() and
SSL_set_strict_cipher_list().  They have two motivations:

First, typos in cipher lists can go undetected for a long time, and
can have surprising consequences when silently ignored.

Second, there is a tendency to use superstition in the construction of
cipher lists, for example by "turning off" things that do not actually
exist.  This leads to the corrosive belief that DEFAULT and ALL ought
not to be trusted.  This belief is false.

The empty session ID case is particularly worth testing to make sure we
don't get confused somewhere. RFC 5077 allows clients to offer tickets
with no session ID. This is absurd since the client then has no way of
detecting resumption except by lookahead. We'll never do this as a
client, but should handle it correctly as a server.

daa0539276 Remove an unnecessary TLS 1.3 ClientHello state.
The TLS 1.2 and 1.3 state machines do the exact same thing at the
beginning. Let them process the ClientHello extensions, etc., and
finalize the certificate in common code. Once we start picking
parameters, we begin to diverge. Everything before this point is
arguably part of setting up the configuration, which is
version-agnostic.

17b3083373 Use a separate timeout scheme for TLS 1.3.
In TLS 1.2, resumption's benefits are more-or-less subsumed by False
Start. TLS 1.2 resumption lifetime is bounded by how much traffic we are
willing to encrypt without fresh key material, so the lifetime is short.
Renewal uses the same key, so we do not allow it to increase lifetimes.

In TLS 1.3, resumption unlocks 0-RTT. We do not implement psk_ke, so
resumption incorporates fresh key material into both encrypted traffic
(except for early data) and renewed tickets. Thus we are both more
willing to and more interested in longer lifetimes for tickets. Renewal
is also not useless. Thus in TLS 1.3, lifetime is bound separately by
the lifetime of a given secret as a psk_dhe_ke authenticator and the
lifetime of the online signature which authenticated the initial
handshake.

This change maintains two lifetimes on an SSL_SESSION: timeout which is
the renewable lifetime of this ticket, and auth_timeout which is the
non-renewable cliff. It also separates the TLS 1.2 and TLS 1.3 timeouts.
The old session timeout defaults and configuration apply to TLS 1.3, and
we define new ones for TLS 1.3.

Finally, this makes us honor the NewSessionTicket timeout in TLS 1.3.
It's no longer a "hint" in 1.3 and there's probably value in avoiding
known-useless 0-RTT offers.

9b16066654 Ignore 0-RTT-capable tickets unless enabled.
Until we've gotten it fully working, we should not mint any of these
SSL_SESSIONs, to avoid constraining future versions of our client code.

Notably, if any of our TLS 1.3 clients today serialized sessions, we
would need to rev the serialization format. Without opting into 0-RTT, a
TLS 1.3 client will create SSL_SESSIONs tagged as 0-RTT-capable but
missing important fields (ALPN, etc.). When that serialized session
makes its way to a future version of our client code, it would disagree
with the server about the ALPN value stored in the ticket and cause
interop failures.

I believe the only client code enabling TLS 1.3 right now is Chrome, and
the window is small, so it should be fine. But fix this now before it
becomes a problem.

958346a5e7 Run select_certificate_cb multiple times
It's not completely clear to me why select_cetificate_cb behaves the way it
does, however not only is it confusing, but it makes assumptions about the
application using BoringSSL (it's not always possible to implement custom
logic outside of the callbacks provided by libssl), that make this callback
somewhat useless.

Case in point, the callback can be used for changing min/max protocol versions
based on per-site policies, and select_certificate_cb is the only place where
SSL_set_min/max_proto_version() can be used (e.g. you can't call them in
cert_cb because it's too late), but the decision on the specific versions to
use might depend on configuration that needs retrieving asynchronously from
over the network, which requires re-running the callback multiple times.

Later I'm hoping we can extend this flag so it drains the unfinished
write and thus test the interaction of read/write paths in 0-RTT. (We
may discover 1-RTT keys while we're in the middle of writing data.)

559f0644a5 Support setting per-connection OCSP staple
Right now the only way to set an OCSP response is SSL_CTX_set_ocsp_response
however this assumes that all the SSLs generated from a SSL_CTX share the
same OCSP response, which is wrong.

This is similar to the OpenSSL "function" SSL_get_tlsext_status_ocsp_resp,
the main difference being that this doesn't take ownership of the OCSP buffer.

In order to avoid memory duplication in case SSL_CTX has its own response,
a CRYPTO_BUFFER is used for both SSL_CTX and SSL.

f01f42a2ce Negotiate ciphers before resumption.
This changes our resumption strategy. Before, we would negotiate ciphers
only on fresh handshakes. On resumption, we would blindly use whatever
was in the session.

Instead, evaluate cipher suite preferences on every handshake.
Resumption requires that the saved cipher suite match the one that would
have been negotiated anyway. If client or server preferences changed
sufficiently, we decline the session.

This is much easier to reason about (we always pick the best cipher
suite), simpler, and avoids getting stuck under old preferences if
tickets are continuously renewed. Notably, although TLS 1.2 ticket
renewal does not work in practice, TLS 1.3 will renew tickets like
there's no tomorrow.

It also means we don't need dedicated code to avoid resuming a cipher
which has since been disabled. (That dedicated code was a little odd
anyway since the mask_k, etc., checks didn't occur. When cert_cb was
skipped on resumption, one could resume without ever configuring a
certificate! So we couldn't know whether to mask off RSA or ECDSA cipher
suites.)

Add tests which assert on this new arrangement.

4eb95ccfd6 Parse ClientHello extensions before deciding on resumption.
This simplifies a little code around EMS and PSK KE modes, but requires
tweaking the SNI code.

The extensions that are more tightly integrated with the handshake are
still processed inline for now. It does, however, require an extra state
in 1.2 so the asynchronous session callback does not cause extensions to
be processed twice. Tweak a test enforce this.

This and a follow-up to move cert_cb before resumption are done in
preparation for resolving the cipher suite before resumption and only
resuming on match.

Note this has caller-visible effects:

- The legacy SNI callback happens before resumption.

- The ALPN callback happens before resumption.

- Custom extension ClientHello parsing callbacks also cannot depend on
  resumption state.

- The DoS protection callback now runs after all the extension callbacks
  as it is documented to be called after the resumption decision.

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.

4199b0d190 Add tests which modify the shim ticket.
The existing tests for this codepath require us to reconfigure the shim.
This will not work when TLS 1.3 cipher configuration is detached from
the old cipher language. It also doesn't hit codepaths like sessions
containing a TLS 1.3 version but TLS 1.2 cipher.

Instead, add some logic to the runner to rewrite tickets and build tests
out of that.

breakage risk, so always do it. This saves us the trouble of having to

There may be something to be said for removing those and having everyone
list dependencies, but I don't really want to chase down every
consumer's build files. Probably not worth the trouble.

a048678cd6 Move some fields from tmp to hs.
This releases memory associated with them after the handshake. Note this
changes the behavior of |SSL_get0_certificate_types| and
|SSL_get_client_CA_list| slightly. Both functions now return NULL
outside of the handshake. But they were already documented to return
something undefined when not called at the CertificateRequest.

A survey of callers finds none that would care. (Note
SSL_get_client_CA_list is used both as a getter for the corresponding
server config setter and to report client handshake properties. Only the
latter is affected.) It's also pretty difficult to imagine why a caller
would wish to query this stuff at any other time, and there are clear
benefits to dropping the CA list after the handshake (some servers send
ABSURDLY large lists).

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.

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.)

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.

f3fbadeae0 Add tests for SSL_peek.
SSL_peek works fine for us, but OpenSSL 1.1.0 regressed this
(https://github.com/openssl/openssl/issues/1563), and we don't have
tests either. Fix this.

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.

e470690633 Align SSL_set_{min,max}_version with upstream.
Upstream added these functions after we did but decided to change the
names slightly. I'm not sure why they wanted to add the "proto" in
there, but align with them nonetheless so the ecosystem only has one set
of these functions.

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.
