It's never called externally and for good reason; the only flag to set is
EVP_MD_CTX_FLAG_NO_INIT which is an implementation detail of EVP_PKEY_HMAC
(hopefully to be removed eventually). Indeed, only EVP_PKEY_HMAC ever calls
this function. Except there's no need to because the HMAC_CTX has already been

The legacy EVP_PKEY_HMAC API has test coverage and still works after this

When the peer or caller requests a renegotiation, OpenSSL doesn't
renegotiate immediately. It sets a flag to begin a renegotiation as soon
as record-layer read and write buffers are clear. One reason is that
OpenSSL's record layer cannot write a handshake record while an
application data record is being written. The buffer consistency checks
around partial writes will break.
None of these cases are relevant for the client auth hack. We already
require that renego come in at a quiescent part of the application
protocol by forbidding handshake/app_data interleave.
The new behavior is now: when a HelloRequest comes in, if the record
layer is not idle, the renegotiation is rejected as if
SSL_set_reject_peer_renegotiations were set. Otherwise we immediately
begin the new handshake. The server may not send any application data
between HelloRequest and completing the handshake. The HelloRequest may
not be consumed if an SSL_write is pending.
Note this does require that Chromium's HTTP stack not attempt to read
the HTTP response until the request has been written, but the
renegotiation logic already assumes it. Were Chromium to drive the
SSL_read state machine early and the server, say, sent a HelloRequest
after reading the request headers but before we've sent the whole POST
body, the SSL state machine may racily enter renegotiate early, block
writing the POST body on the new handshake, which would break Chromium's
ERR_SSL_CLIENT_AUTH_CERT_NEEDED plumbing.

The only case where renego is supported is if we are a client and the

work.
The messy logic where the handshake loop is repurposed to send
HelloRequest and the extremely confusing tri-state s->renegotiate (which
makes SSL_renegotiate_pending a lie during the initial handshake as a
server) are now gone. The next change will further simplify things by
removing ssl->s3->renegotiate and the renego deferral logic. There's
also some server-only renegotiation checks that can go now.
Also clean up ssl3_read_bytes' HelloRequest handling. The old logic relied on
the handshake state machine to reject bad HelloRequests which... actually that
code probably lets you initiate renego by sending the first four bytes of a
ServerHello and expecting the peer to read it later.

wrec altogether. SSL3_RECORD is now only used to maintain state about

- APIs to configure SSL_CTX/SSL, roughly grouped by feature. Probably
options and modes are the first two sections. SSL_TXT_* constants can
be part of documenting cipher suite configuration.
- APIs to query state from SSL_CTX/SSL, roughly grouped by feature. (Or
perhaps these should be folded into the configuration sections?)

This cuts down on one config knob as well as one case in the renego
combinatorial explosion. Since the only case we care about with renego
is the client auth hack, there's no reason to ever do resumption.
Especially since, no matter what's in the session cache:
- OpenSSL will only ever offer the session it just established,
whether or not a newer one with client auth was since established.
- Chrome will never cache sessions created on a renegotiation, so
such a session would never make it to the session cache.
- The new_session + SSL_OP_NO_SESSION_RESUMPTION_ON_RENEGOTIATION
logic had a bug where it would unconditionally never offer tickets
(but would advertise support) on renego, so any server doing renego
resumption against an OpenSSL-derived client must not support
session tickets.
This also gets rid of s->new_session which is now pointless.

because it's always 2 after ClientHello), and s->s3->tmp.finish_md_len

some of the others later; notably s->renegotiate can go away when
initiating renegotiation is removed.
This also tidies up the extensions to be consistent about whether
they're allowed during renego:
- ALPN failed to condition when accepting from the server, so even
if the client didn't advertise, the server could.
- SCTs now *are* allowed during renego. I think forbidding it was a
stray copy-paste. It wasn't consistently enforced in both ClientHello
and ServerHello, so the server could still supply it. Moreover, SCTs
are part of the certificate, so we should accept it wherever we accept
certificates, otherwise that session's state becomes incomplete. This
matches OCSP stapling. (NB: Chrome will never insert a session created
on renego into the session cache and won't accept a certificate
change, so this is moot anyway.)

Next batch. Mostly a bunch of deprecated things. This switches
SSL_CTX_set_tmp_rsa from always failing to always succeeding. The latter
is probably a safer behavior; a consumer may defensively set a temporary
RSA key. We'll successfully "set it" and just never use the result.

This is an API wart that makes it easy to accidentally reuse the server
DHE half for every handshake. It's much simpler to have only one mode.
This mirrors the change made to the ECDHE code; align with that logic.

This is a really dumb API wart. Now that we have a limited set of curves that
are all reasonable, the automatic logic should just always kick in. This makes
set_ecdh_auto a no-op and, instead of making it the first choice, uses it as
the fallback behavior should none of the older curve selection APIs be used.
Currently, by default, server sockets can only use the plain RSA key exchange.
