This partitions the session ID space of the internal cache by version,
which is nominally something we want, but we must check the version
externally anyway for both tickets and external session cache. That
makes this measure redundant. (Servers generate session IDs and 2^256 is
huge, so there would never accidentally be a collision.)
This cuts down on the "key" in the internal session cache, which will
simplify adding something like an lh_SSL_SESSION_retrieve_key function.

partially-initialized structs. C++ is a bit more finicky about this.)

Update-Note: This tweaks the SSL_shutdown behavior. OpenSSL's original
SSL_shutdown behavior was an incoherent mix of discarding the record and
rejecting it (it would return SSL_ERROR_SYSCALL but retrying the
operation would discard it). SSLeay appears to have intended to discard
it, so we previously "fixed" it actually discard.
However, this behavior is somewhat bizarre and means we skip over
unbounded data, which we typically try to avoid. If you are trying to
cleanly shutdown the TLS portion of your protocol, surely it is at a
point where additional data is a syntax error. I suspect I originally
did not realize that, because the discarded record did not properly
continue the loop, SSL_shutdown would appear as if it rejected the data,
and so it's unlikely anyone was relying on that behavior.
Discussion in https://github.com/openssl/openssl/pull/6340 suggests
(some of) upstream also prefers rejecting.

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

|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.

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

Therefore this change will be used to filter latency measurements in

This also makes it an error if the server didn't echo an extension of

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
was deprecated in TLS 1.3), so reject them. Both Internet Explorer and
Firefox appear to reject them already.
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
as new protocols should use curve25519.

This change adds a couple of focused tests to ssl_test.cc, but also
programmically duplicates many runner tests in a split-handshake mode.

Update-Note: Now that tls13_experiment2 is gone, the server should remove the set_tls13_variant call. To avoid further churn, we'll make the server default for future variants to be what we'd like to deploy.

Mono's legacy TLS 1.0 stack, as a server, does not implement any form of
resumption, but blindly echos the ClientHello session ID in the
ServerHello for no particularly good reason.
This is invalid, but due to quirks of how our client checked session ID
equality, we only noticed on the second connection, rather than the
first. Flaky failures do no one any good, so break deterministically on
the first connection, when we realize something strange is going on.
