Chromium uses a zygote process and a sandbox on Linux. In order for RAND_bytes
to be functional and guaranteed fork-safe inside the renderers, /dev/urandom
must be prewarmed. Calling RAND_bytes initializes a thread-local ChaCha20 key
when rdrand is available. So that key is fork-safe and to avoid tempting any
dragons by touching pthreads APIs before a non-exec fork, add a
RAND_set_urandom_fd API. It allows the consumer to supply the /dev/urandom fd
and promises to be fork-safe, both in initializing key material and use of
pthreads.

The old session isn't pruned as we haven't processed the Finished message yet.
RFC 5077 says:
The server MUST NOT assume that the client actually received the updated
ticket until it successfully verifies the client's Finished message.
Moreover, because network messages are asynchronous, a new SSL connection may
have began just before the client received the new ticket, so any such servers

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
server sends a HelloRequest. That is still needed to support the renego
+ client auth hack in Chrome. Beyond that, no other forms of renego will
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.

Now that WebRTC honors packet boundaries (https://crbug.com/447431), we
can start enforcing them correctly. Configuring read-ahead now does
nothing. Instead DTLS will always set "read-ahead" and also correctly
enforce packet boundaries when reading records. Add tests to ensure that
badly fragmented packets are ignored. Because such packets don't fail
the handshake, the tests work by injecting an alert in the front of the
handshake stream and ensuring the DTLS implementation ignores them.
ssl3_read_n can be be considerably unraveled now, but leave that for
future cleanup. For now, make it correct.

tls1_enc is now SSL_AEAD_CTX_{open,seal}. This starts tidying up a bit
of the record-layer logic. This removes rr->input, as encrypting and
decrypting records no longer refers to various globals. It also removes
wrec altogether. SSL3_RECORD is now only used to maintain state about
the current incoming record. Outgoing records go straight to the write
buffer.
This also removes the outgoing alignment memcpy and simply calls
SSL_AEAD_CTX_seal with the parameters as appropriate. From bssl speed
tests, this seems to be faster on non-ARM and a bit of a wash on ARM.
Later it may be worth recasting these open/seal functions to write into
a CBB (tweaked so it can be malloc-averse), but for now they take an
out/out_len/max_out trio like their EVP_AEAD counterparts.

Current thought is to organize this by:
- Core SSL_CTX APIs (creating, destroying)
- Core SSL APIs (creating destroying, maybe handshake, read, write as
well)
- 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?)
The functions themselves aren't reordered or reorganized to match the
eventual header order yet. Though I did do the s -> ssl rename on the
ones I've touched.
Also formally deprecate SSL_clear. It would be a core SSL API

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.

There's multiple different versions of this check, between
s->s3->have_version (only works at some points), s->new_session (really
weird and not actually right), s->renegotiate (fails on the server
because it's always 2 after ClientHello), and s->s3->tmp.finish_md_len
(super confusing). Add an explicit bit with clear meaning. We'll prune
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.)

These are never used and no flags are defined anyway.

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.

054e682675 removed the compatibility include of
mem.h in crypto.h. mem.h doesn't exist in upstream which defines these
functions in crypto.h instead. The compatibility include should probably be
restored to avoid causing all kinds of grief when porting consumers over.

CRYPTO_MUTEX was the wrong size. Fortunately, Apple was kind enough to define
pthread_rwlock_t unconditionally, so we can be spared fighting with feature
macros. Some of the stdlib.h removals were wrong and clang is pick about
multiply-defined typedefs. Apparently that's a C11 thing?

This is taken from upstream, although it originally came from us. This
will only take effect on 64-bit systems (x86-64 and aarch64).
Before:
Did 1496 ECDH P-256 operations in 1038743us (1440.2 ops/sec)
Did 2783 ECDSA P-256 signing operations in 1081006us (2574.5 ops/sec)
Did 2400 ECDSA P-256 verify operations in 1059508us (2265.2 ops/sec)
After:
Did 4147 ECDH P-256 operations in 1061723us (3905.9 ops/sec)
Did 9372 ECDSA P-256 signing operations in 1040589us (9006.4 ops/sec)

Instead, each module defines a static CRYPTO_EX_DATA_CLASS to hold the values.
This makes CRYPTO_cleanup_all_ex_data a no-op as spreading the
CRYPTO_EX_DATA_CLASSes across modules (and across crypto and ssl) makes cleanup
slightly trickier. We can make it do something if needbe, but it's probably not
worth the trouble.

No wrappers were ever added and codesearch confirms no one ever added to it
manually. Probably anyone doing complex things with BIOs just made a custom
BIO_METHOD. We can put it back with proper functions if the need ever arises.
