We have a successful TLS 1.3 deployment, in spite of non-compliant
middleboxes everywhere, so now let's get this optimization in. It would
have been nice to test with this from the beginning, but sadly we forgot
about it. Ah well. This shaves 63 bytes off the server's first flight,
and then another 21 bytes off the pair of NewSessionTickets.
So we'll more easily notice in case of anything catastrophic, tie this
behavior to draft 28.
Update-Note: This slightly tweaks our draft-28 behavior.

This is so Chromium can verify the session before offering it, rather
than doing it after the handshake (at which point it's too late to punt
the session) as we do today. This should, in turn, allow us to finally
verify certificates off a callback and order it correctly relative to
CertificateRequest in TLS 1.3.
(It will also order "correctly" in TLS 1.2, but this is useless. TLS 1.2
does not bind the CertificateRequest to the certificate at the point the
client needs to act on it.)

Previously, we'd omitted OpenSSL's OCSP APIs because they depend on a
complex OCSP mechanism and encourage the the unreliable server behavior
that hampers using OCSP stapling to fix revocation today. (OCSP
responses should not be fetched on-demand on a callback. They should be
managed like other server credentials and refreshed eagerly, so
temporary CA outage does not translate to loss of OCSP.)
But most of the APIs are byte-oriented anyway, so they're easy to
support. Intentionally omit the one that takes a bunch of OCSP_RESPIDs.
The callback is benign on the client (an artifact of OpenSSL reading
OCSP and verifying certificates in the wrong order). On the server, it
encourages unreliability, but pyOpenSSL/cryptography.io depends on this.
Dcument that this is only for compatibility with legacy software.
Also tweak a few things for compatilibility. cryptography.io expects
SSL_CTX_set_read_ahead to return something, SSL_get_server_tmp_key's
signature was wrong, and cryptography.io tries to redefine
SSL_get_server_tmp_key if SSL_CTRL_GET_SERVER_TMP_KEY is missing.

All CBC ciphers in TLS are broken and insecure. TLS 1.2 introduced
AEAD-based ciphers which avoid their many problems. It also introduced
new CBC ciphers based on HMAC-SHA256 and HMAC-SHA384 that share the same
flaws as the original HMAC-SHA1 ones. These serve no purpose. Old
clients don't support them, they have the highest overhead of all TLS
ciphers, and new clients can use AEADs anyway.
Remove them from libssl. This is the smaller, more easily reverted
portion of the removal. If it survives a week or so, we can unwind a lot
more code elsewhere in libcrypto. This removal will allow us to clear
some indirect calls from crypto/cipher_extra/tls_cbc.c, aligning with

Chrome needs to support renegotiation at TLS 1.2 + HTTP/1.1, but we're
free to shed the handshake configuration at TLS 1.3 or HTTP/2.
Rather than making config shedding implicitly disable renegotiation,
make the actual shedding dependent on a combination of the two settings.
If config shedding is enabled, but so is renegotiation (including
whether we are a client, etc.), leave the config around. If the
renegotiation setting gets disabled again after the handshake,
re-evaluate and shed the config then.

|SSL_CONFIG| is a container for bits of configuration that are
unneeded after the handshake completes. By default it is retained for
the life of the |SSL|, but it may be shed at the caller's option by
calling SSL_set_shed_handshake_config(). This is incompatible with
renegotiation, and with SSL_clear().
|SSL_CONFIG| is reachable by |ssl->config| and by |hs->config|. The
latter is always non-NULL. To avoid null checks, I've changed the
signature of a number of functions from |SSL*| arguments to
|SSL_HANDSHAKE*| arguments.
When configuration has been shed, setters that touch |SSL_CONFIG|
return an error value if that is possible. Setters that return |void|
do nothing.
Getters that request |SSL_CONFIG| values will fail with an |assert| if
the configuration has been shed. When asserts are compiled out, they
will return an error value.
The aim of this commit is to simplify analysis of split-handshakes by
making it obvious that some bits of state have no effects beyond the
handshake. It also cuts down on memory usage.
Of note: |SSL_CTX| is still reachable after the configuration has been
shed, and a couple things need to be retained only for the sake of
post-handshake hooks. Perhaps these can be fixed in time.

In the handoff+handback case, bssl_shim.cc creates 3 |SSL| objects:
one to receive the ClientHello, one to receive the handoff, and a
third one to receive the handback.
Before 56986f9, only the first of these received any configuration.
Since that commit, all 3 of them receive the same configuration. That
means that the handback message no longer needs to serialize as many
things.
N.B. even before 56986f9, not all of the fields were necessary. For
example, there was no reason to serialize |conf_max_version| and
|conf_min_version| in the handback, so far as I can tell.
This commit is mechanical: it simply removes everything that doesn't
cause any tests to fail. In the long run, I'll need to carefully
check for two possibilities:
- Knobs that affect the handshake after the server's first message it
sent. These are troublesome because that portion of the handshake
may run on a different |SSL|, depending on whether the handback is
early or late.
- Getters that may be called post-handshake, and that callers may
reasonably expect to reflect the value that was used during
handshake.

So our tests are usable for other stacks, send a fake session ID in the

BoringSSL behaves as we expect it to on empty session IDs too. The

On reflection, I think we'll need to note whether dummy PQ padding was
echoed on a given connection. Otherwise measurements in Chrome will be
mixed with cases where people have MITM proxies that ignored the
extension, or possibly Google frontends that haven't been updated.
Therefore this change will be used to filter latency measurements in
Chrome to only include those where the extension was echoed and we'll
measure at levels of 1 byte (for control), 400 bytes, and 1100 bytes.
This also makes it an error if the server didn't echo an extension of
the same length as was sent.

In this round, Google servers will echo the extension in order to test
the latency of both parties sending a PQ key-agreement message.
The extension is sent (and echoed) for both full and resumption
handshakes. This is intended to mirror the overhead of TLS 1.3 (even
when using TLS 1.2), as a resumption in TLS 1.3 still does a fresh key
agreement.

We don't advertise compressed coordinates (and point format negotiation

Later I hope to add an easier to use ECDH API that acts on bytes, not
EC_POINT. This clears the way for that API to only accept uncompressed
coordinates. Compressed coordinates never got deployed over NIST curves,
for better or worse. At this point, there is no sense in changing that

The private key callback may not push one of its own (it's possible to
register a custom error library and whatnot, but this is tedious). If
the callback does not push any, we report SSL_ERROR_SYSCALL. This is not
completely wrong, as "syscall" really means "I don't know, something you
gave me, probably the BIO, failed so I assume you know what happened",
but most callers just check errno. And indeed cert_cb pushes its own
error, so this probably should as well.
Update-Note: Custom private key callbacks which push an error code on
failure will report both that error followed by
SSL_R_PRIVATE_KEY_OPERATION_FAILED. Callbacks which did not push any
error will switch from SSL_ERROR_SYSCALL to SSL_ERROR_SSL with
SSL_R_PRIVATE_KEY_OPERATION_FAILED.

This extension will be used to measure the latency impact of potentially
sending a post-quantum key share by default. At this time it's purely
measuring the impact of the client sending the key share, not the server
replying with a ciphertext.
We could use the existing padding extension for this but that extension
doesn't allow the server to echo it, so we would need a different
extension in the future anyway. Thus we just create one now.
We can assume that modern clients will be using TLS 1.3 by the time that
PQ key-exchange is established and thus the key share will be sent in
all ClientHello messages. However, since TLS 1.3 isn't quite here yet,
this extension is also sent for TLS 1.0–1.2 ClientHellos. The latency
impact should be the same either way.

TLS 1.3 includes a server-random-based anti-downgrade signal, as a
workaround for TLS 1.2's ServerKeyExchange signature failing to cover
the entire handshake. However, because TLS 1.3 draft versions are each
doomed to die, we cannot deploy it until the final RFC. (Suppose a
draft-TLS-1.3 client checked the signal and spoke to a final-TLS-1.3
server. The server would correctly negotiate TLS 1.2 and send the
signal. But the client would then break. An anologous situation exists
with reversed roles.)
However, it appears that Cisco devices have non-compliant TLS 1.2
implementations[1] and copy over another server's server-random when
acting as a TLS terminator (client and server back-to-back).
Hopefully they are the only ones doing this. Implement a
measurement-only version with a different value. This sentinel must not
be enforced, but it will tell us whether enforcing it will cause
problems.
