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.

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

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.

If the ticket extension is non-empty, then the ID is not an ID but a

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.)

prefix does, but we only support renego for the mid-stream HTTP/1.1

HTTPS clients should be requiring the certificate be unchanged across
renego which makes this moot.)
Ultimately, an application which makes the mistake of using
renegotiation needs to be aware of what exactly that means and how to

so this is a tenable requirement.

This fixes a number of bugs with the original logic:
- If handshake messages are fragmented and writes need to be retried, frag_off
gets completely confused.
- The BIO_flush call didn't set rwstate, so it wasn't resumable at that point.
- The msg_callback call gets garbage because the fragment header would get
scribbled over the handshake buffer.
The original logic was also extremely confusing with how it handles init_off.
(init_off gets rewound to make room for the fragment header. Depending on
where you pause, resuming may or may not have already been rewound.)
For simplicity, just allocate a new buffer to assemble the fragment in and
avoid clobbering the old one. I don't think it's worth the complexity to
optimize that. If we want to optimize this sort of thing, not clobbering seems
better anyway because the message may need to be retransmitted. We could avoid
doing a copy when buffering the outgoing message for retransmission later.
We do still need to track how far we are in sending the current message via
init_off, so I haven't opted to disconnect this function from
init_{buf,off,num} yet.
Test the fix to the retry + fragment case by having the splitHandshake option
to the state machine tests, in DTLS, also clamp the MTU to force handshake
fragmentation.

only accept the first renego.
Also, this API doesn't repeat the mistake I made with
SSL_set_reject_peer_renegotiations which is super-confusing with the negation.

SSL 3.0 used to have a nice and simple rule around extensions. They don't
exist. And then RFC 5746 came along and made this all extremely confusing.
In an SSL 3.0 server, rather than blocking ServerHello extension
emission when renegotiation_info is missing, ignore all ClientHello
extensions but renegotiation_info. This avoids a mismatch between local
state and the extensions with emit.
Notably if, for some reason, a ClientHello includes the session_ticket
extension, does NOT include renegotiation_info or the SCSV, and yet the
client or server are decrepit enough to negotiate SSL 3.0, the
connection will fail due to unexpected NewSessionTicket message.
See https://crbug.com/425979#c9 for a discussion of something similar
that came up in diagnosing https://poodle.io/'s buggy POODLE check.
This is analogous to upstream's
5a3d8eebb7667b32af0ccc3f12f314df6809d32d.
(Not supporting renego as a server in any form anyway, we may as well
completely ignore extensions, but then our extensions callbacks can't
assume the parse hooks are always called. This way the various NULL
handlers still function.)

This change makes the runner tests (in ssl/test/runner) act like a
normal Go test rather than being a Go binary. This better aligns with
some internal tools.
Thus, from this point onwards, one has to run the runner tests with `go
test` rather than `go run` or `go build && ./runner`.
This will break the bots.
