JDK 11 shipped with a TLS 1.3 implementation enabled by default.
Unfortunately, that implementation does not work and fails to send the
SNI extension on resumption. See
https://bugs.openjdk.java.net/browse/JDK-8211806.
This means servers which enable TLS 1.3 will see JDK 11 clients work on
the first connection and then fail on all subsequent connections. Add
SSL_set_jdk11_workaround which configures a workaround to fingerprint
JDK 11 and disable TLS 1.3 with the faulty clients.
JDK 11 also implemented the downgrade signal, which means that
connections that trigger the workaround also must not send the downgrade
signal. Unfortunately, the downgrade signal's security properties are
sensitive to the existence of any unmarked TLS 1.2 ServerHello paths. To
salvage this, pick a new random downgrade marker for this scenario and
modify the client to treat it as an alias of the standard one.
Per the link above, JDK 11.0.2 will fix this bug. Hopefully the
workaround can be retired sometime after it is released.

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.

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

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

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.
