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.

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.

|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 means knobs like SendClientVersion and SendServerVersion deal with

SendFoo is just a weird post-processing bit on the handshake messages

If we add new ciphers and curves, presumably we prefer them over current

Add two new extensions, one empty and one non-empty. Place the empty one

fuzz more code, align Go with C. Fuzzer mode TLS 1.3 still pads but

- 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

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.

message is always fatal.
We don't appear to be the cause of Chrome's recent

If the early callback fails, handshake_failure seems the most

internal_error

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

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.

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.

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.

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.

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.)

This change allows the shim to return a magic error code (89) to
indicate that it doesn't implement some of the given flags for a test.
Unimplemented tests are, by default, an error. The --allow-unimplemented

This is done in preparation for non-BoringSSL shims.

Alas, we will need a version fallback for TLS 1.3 again.
This deprecates SSL_MODE_SEND_FALLBACK_SCSV. Rather than supplying a
boolean, have BoringSSL be aware of the real maximum version so we can
change the TLS 1.3 anti-downgrade logic to kick in, even when
max_version is set to 1.2.
The fallback version replaces the maximum version when it is set for
almost all purposes, except for downgrade protection purposes.

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.)

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.

This isn't filled in on the client and Chromium no longer uses it for
plain RSA. It's redundant with existing APIs. This is part of removing
the need for callers to call SSL_get_session where possible.
SSL_get_session is ambiguous when it comes to renego. Some code wants
the current connection state which should not include the pending
handshake and some code wants the handshake scratch space which should.
Renego doesn't exist in TLS 1.3, but TLS 1.3 makes NewSessionTicket a
post-handshake message, so SSL_get_session is somewhat silly of an API
there too.
SSL_SESSION_get_key_exchange_info is a BoringSSL-only API, so we can
freely change it and replace it with APIs keyed on SSL. In doing so, I
think it is better to provide APIs like "SSL_get_dhe_group_size" and
"SSL_get_curve_id" rather than make the caller do the multi-step
SSL_get_current_cipher / SSL_CIPHER_is_ECDHE dance. To that end, RSA
key_exchange_info is pointless as it can already be determined from the
peer certificate.

public key to be sent to the peer, and another to produce the shared key
upon receipt of the peer's message.
This API does not work for NEWHOPE, because the client-to-server message
cannot be produced until the server's message has been received by the
client.
Solve this by introducing a new method which consumes data from the
server key exchange message and produces data for the client key
exchange message.

OpenSSL used to only forbid it on the server in plain PSK and allow it on the
client. Enforce it properly on both sides. My read of the rule in RFC 5246 ("A
non-anonymous server can optionally request a certificate") and in RFC 4279
("The Certificate and CertificateRequest payloads are omitted from the
response.") is that client auth happens iff we're certificate-based.
The line in RFC 4279 is under the plain PSK section, but that doesn't make a
whole lot of sense and there is only one diagram. PSK already authenticates
both sides. I think the most plausible interpretation is that this is for
certificate-based ciphers.

we decided to tolerate this. Add a test for this so that we check this

This test also ensures that the original session's value for it carries over.

The DTLS bbio logic is rather problematic, but this shouldn't make things
worse. In the in-handshake case, the new code merges the per-message
(unchecked) BIO_flush calls into one call at the end but otherwise the BIO is
treated as is. Otherwise any behavior around non-block writes should be
preserved.
In the post-handshake case, we now install the buffer when we didn't
previously. On write error, the buffer will have garbage in it, but it will be
discarded, so that will preserve any existing retry behavior. (Arguably the
existing retry behavior is a bug, but that's another matter.)
Add a test for all this, otherwise it is sure to regress. Testing for
record-packing is a little fuzzy, but we can assert ChangeCipherSpec always
shares a record with something.

In TLS, you never skip the Certificate message. It may be empty, but its
presence is determined by CertificateRequest. (This is sensible.)
In SSL 3.0, the client omits the Certificate message. This means you need to
probe and may receive either Certificate or ClientKeyExchange (thankfully,
ClientKeyExchange is not optional, or we'd have to probe at ChangeCipherSpec).
We didn't have test coverage for this, despite some of this logic being a

If a Read or Write blocks for too long, time out the operation. Otherwise, some
kinds of test failures result in hangs, which prevent the test harness from
progressing. (Notably, OpenSSL currently has a lot of those failure modes and
upstream expressed interest in being able to run the tests to completion.)
Go's APIs want you to send an absolute timeout, to avoid problems when a Read
is split into lots of little Reads. But we actively want the timer to reset in
that case, so this needs a trivial adapter.
The default timeout is set at 15 seconds for now. If this becomes a problem, we
can extend it or build a more robust deadlock detector given an out-of-band
channel (shim tells runner when it's waiting on data, abort if we're also
waiting on data at the same time). But I don't think we'll need that
complexity. 15 seconds appears fine for both valgrind and running tests on a
Nexus 4.

Both sides' signature and Finished checks still occur, but the results

Conveniently, this isn't that much code since all ciphers and their size

There is little risk that anyone will ship a BORINGSSL_UNSAFE_FUZZER_MODE build

Take the mappings for MD5 and SHA-224 values out of the code altogether. This
aligns with the current TLS 1.3 draft.
For MD5, this is a no-op. It is not currently possible to configure accepted
signature algorithms, MD5 wasn't in the hardcoded list, and we already had a
test ensuring we enforced our preferences correctly. MD5 also wasn't in the
default list of hashes our keys could sign and no one overrides it with a
different hash.
For SHA-224, this is not quite a no-op. The hardcoded accepted signature
algorithms list included SHA-224, so this will break servers relying on that.
However, Chrome's metrics have zero data points of servers picking SHA-224 and
no other major browser includes it. Thus that should be safe.
SHA-224 was also in the default list of hashes we are willing to sign. For
client certificates, Chromium's abstractions already did not allow signing
SHA-224, so this is a no-op there. For servers, this will break any clients
which only accept SHA-224. But no major browsers do this and I am not aware of
any client implementation which does such ridiculous thing.
(SHA-1's still in there. Getting rid of that one is going to take more effort.)

For TLS, this machinery only exists to swallow no_certificate alerts
which only get sent in an SSL 3.0 codepath anyway. It's much less a
no-op for SSL 3.0 which, strictly speaking, has only a subset of TLS's
alerts.
This gets messy around version negotiation because of the complex
relationship between enc_method, have_version, and version which all get
set at different times. Given that SSL 3.0 is nearly dead and all these
alerts are fatal to the connection anyway, this doesn't seem worth
carrying around. (It doesn't work very well anyway. An SSLv3-only server
may still send a record_overflow alert before version negotiation.)
This removes the last place enc_method is accessed prior to version
negotiation.

This is a minor regression from
https://boringssl-review.googlesource.com/5235.
If the client, for whatever reason, had an ID-based session but also
supports tickets, it will send non-empty ID + empty ticket extension.
If the ticket extension is non-empty, then the ID is not an ID but a
dummy signaling value, so 5235 avoided looking it up. But if it is
present and empty, the ID is still an ID and should be looked up.
This shouldn't have any practical consequences, except if a server
switched from not supporting tickets and then started supporting it,
while keeping the session cache fixed.
Add a test for this case, and tighten up existing ID vs ticket tests so
they fail if we resume with the wrong type.

The new curve is not enabled by default.
As EC_GROUP/EC_POINT is a bit too complex for X25519, this introduces an
SSL_ECDH_METHOD abstraction which wraps just the raw ECDH operation. It
also tidies up some of the curve code which kept converting back and
force between NIDs and curve IDs. Now everything transits as curve IDs
except for API entry points (SSL_set1_curves) which take NIDs. Those
convert immediately and act on curve IDs from then on.
Note that, like the Go implementation, this slightly tweaks the order of
operations. The client sees the server public key before sending its
own. To keep the abstraction simple, SSL_ECDH_METHOD expects to
generate a keypair before consuming the peer's public key. Instead, the
client handshake stashes the serialized peer public value and defers
parsing it until it comes time to send ClientKeyExchange. (This is
analogous to what it was doing before where it stashed the parsed peer
public value instead.)
It still uses TLS 1.2 terminology everywhere, but this abstraction should also
be compatible with TLS 1.3 which unifies (EC)DH-style key exchanges.
(Accordingly, this abstraction intentionally does not handle parsing the
ClientKeyExchange/ServerKeyExchange framing or attempt to handle asynchronous
plain RSA or the authentication bits.)
