8aae8a126b Remove M_i2d_* and M_d2i_*.
Somehow I didn't notice these used i2d_ASN1_bytes and
d2i_ASN1_type_bytes when removing those. Fortunately the macros are also
removable so drop them too.

1db42fb3ca Clarify CBS/CBB with respect to high tag number form.
We may need to implement high tag number form someday. CBS_get_asn1 has
an unsigned output to allow for this, but CBB_add_asn1 takes a uint8_t
(I think this might be my fault). Fix that which also fixes a
-Wconversion warning.

Simply leaving room in tag representation will still cause troubles
because the class and constructed bits overlap with bits for tag numbers
above 31. Probably the cleanest option would be to shift them to the top
3 bits of a u32 and thus not quite match the DER representation. Then
CBS_get_asn1 and CBB_add_asn1 will internally munge that into the DER
representation and consumers may continue to write things like:

   tag_number | CBS_ASN1_CONTEXT_SPECIFIC

I haven't done that here, but in preparation for that, document that
consumers need to use the values and should refrain from assuming the
correspond to DER.

0fc37ef082 Fix a number of sigalg scope issues.
peer_sigalgs should live on SSL_HANDSHAKE. This both releases a little
bit of memory after the handshake is over and also avoids the bug where
the sigalgs get dropped if SSL_set_SSL_CTX is called at a bad time. See
also upstream's 14e14bf6964965d02ce89805d9de867f000095aa.

This only affects consumers using the old SNI callback and not
select_certificate_cb.

Add a test that the SNI callback works as expected. In doing so, add an
SSL_CTX version of the signing preferences API. This is a property of
the cert/key pair (really just the key) and should be tied to that. This
makes it a bit easier to have the regression test work with TLS 1.2 too.

I thought we'd fixed this already, but apparently not... :-/

7aa31d68fc Remove ssl->verify_result.
Having two copies of this is confusing. This field is inherently tied to
the certificate chain, which lives on SSL_SESSION, so this should live
there too. This also wasn't getting reset correctly on SSL_clear, but
this is now resolved.

93d9743def Deprecate and no-op SSL_set_verify_result.
As documented by OpenSSL, it does not interact with session resumption
correctly:
https://www.openssl.org/docs/manmaster/ssl/SSL_set_verify_result.html

Sadly, netty-tcnative calls it, but we should be able to get them to
take it out because it doesn't do anything. Two of the three calls are
immediately after SSL_new. In OpenSSL and BoringSSL as of the previous
commit, this does nothing.

The final call is in verify_callback (see SSL_set_verify). This callback
is called in X509_verify_cert by way of X509_STORE_CTX_set_verify_cb.
As soon as X509_verify_cert returns, ssl->verify_result is clobbered
anyway, so it doesn't do anything.

Within OpenSSL, it's used in testdane.c. As far as I can tell, it does
not actually do a handshake and just uses this function to fake having
done one. (Regardless, we don't need to build against that.)

This is done in preparation for removing ssl->verify_result in favor of
session->verify_result.

25fe85b38c Insert a state before cert_cb.
If cert_cb runs asynchronously, we end up repeating a large part of very
stateful ClientHello processing. This seems to be mostly fine and there
are few users of server-side cert_cb (it's a new API in 1.0.2), but it's
a little scary.

This is also visible to external consumers because some callbacks get
called multiple times. We especially should try to avoid that as there
is no guarantee that these callbacks are idempotent and give the same
answer each time.

a432757acb Use BN_mod_inverse_odd instead of |BN_mod_inverse| for ECC.
BN_mod_inverse_odd was always being used on 64-bit platforms and was being used
for all curves with an order of 450 bits or smaller (basically, everything but
P-521). We generally don't care much about minor differences in the speed of
verifying signatures using curves other than P-256 and P-384. It is better to
always use the same algorithm.

This also allows |bn_mod_inverse_general|, |bn_mod_inverse_no_branch|, and
|BN_mod_inverse| to be dropped from programs that can somehow avoid linking in
the RSA key generation and RSA CRT recovery code.

33dad1b7a1 Stop pretending to ssl_clear_bad_session.
We broke this to varying degrees ages ago.

This is the logic to implement the variations of rules in TLS to discard
sessions after a failed connection, where a failed connection could be
one of:

- A connection that was not cleanly shut down.

- A connection that received a fatal alert.

The first one is nonsense since close_notify does not actually work in
the real world. The second is a vaguely more plausible but...

- A stateless ticket-based server can't drop sessions anyway.

- In TLS 1.3, a client may receive many tickets over the lifetime of a
  single connection. With an external session cache like ours which may,
  in theory, but multithreaded, this will be a huge hassle to track.

- A client may well attempt to establish a connection and reuse the
  session before we receive the fatal alert, so any application state we
  hope to manage won't really work.

- An attacker can always close the connection before the fatal alert, so
  whatever security policy clearing the session gave is easily
  bypassable.

Implementation-wise, this has basically never worked. The
ssl_clear_bad_session logic called into SSL_CTX_remove_session which
relied on the internal session cache. (Sessions not in the internal
session cache don't get removed.) The internal session cache was only
useful for a server, where tickets prevent this mechanism from doing
anything. For a client, we since removed the internal session cache, so
nothing got removed. The API for a client also did not work as it gave
the SSL_SESSION, not the SSL, so a consumer would not know the key to
invalidate anyway.

The recent session state splitting change further broke this.

Moreover, calling into SSL_CTX_remove_session logic like that is
extremely dubious because it mutates the not_resumable flag on the
SSL_SESSION which isn't thread-safe.

Spec-wise, TLS 1.3 has downgraded the MUST to a SHOULD.

Given all that mess, just remove this code. It is no longer necessary to
call SSL_shutdown just to make session caching work.

1e6f11a7ff Adding NewSessionTicket.
We will now send tickets as a server and accept them as a
client. Correctly offering and resuming them in the handshake will be
implemented in a follow-up.

Now that we're actually processing draft 14 tickets, bump the draft
version.

ce079fda12 Add SSL_is_dtls.
OpenSSL 1.1.0 added a function to tell if an SSL* is DTLS or not. This
is probably a good idea, especially since SSL_version returns
non-normalized versions.

78f84f4e03 Document a conservative input range for Montgomery math functions.
The functions appear to try to handle negative inputs, but it isn't
clear how negative inputs are supposed to work and/or if these
functions work the way they are supposed to given negative inputs.
There seems to be no legitimate reason to pass these functions negative
inputs, so just document that negative inputs shouldn't be used. More
specifically, document that the inputs should be in the range [0, n)
where |n| is the Montgomery modulus.

4501bd5118 Align with OpenSSL on SSL_set_bio behavior.
SSL_set_bio is a nightmare.

In f715c42322, we noticed that, among
other problems, SSL_set_bio's actual behavior did not match how
SSL_set_rfd was calling it due to an asymmetry in the rbio/wbio
handling. This resulted in SSL_set_fd/SSL_set_rfd calls to crash.  We
decided that SSL_set_rfd's believed semantics were definitive and
changed SSL_set_bio.

Upstream, in 65e2d672548e7c4bcb28f1c5c835362830b1745b, decided that
SSL_set_bio's behavior, asymmetry and all, was definitive and that the
SSL_set_rfd crash was a bug in SSL_set_rfd. Accordingly, they switched
the fd callers to use the side-specific setters, new in 1.1.0.

Align with upstream's behavior and add tests for all of SSL_set_bio's
insanity. Also export the new side-specific setters in anticipation of
wanting to be mostly compatible with OpenSSL 1.1.0.

0375127606 Promise more accurate bounds than EVP_MD_MAX_SIZE.
A caller using EVP_Digest* which a priori knows tighter bounds on the
hash function used (perhaps because it is always a particular hash) can
assume the function will not write more bytes than the size of the hash.

The letter of the rules before vaguely[*] allowed for more than
EVP_MD_MAX_SIZE bytes written which made for some unreasonable code in
Chromium. Officially clarify this and add tests which, when paired with
valgrind and ASan prove it.

BUG=59

[*] Not really. I think it already promised the output length will be
both the number of bytes written and the size of the hash and the size
of the hash is given by what the function promises to compute. Meh.

87eab4902d Splitting SSL session state.
To prevent configuration/established session confusion, the handshake
session state is separated into the configured session (ssl->session)
and the newly created session (ssl->s3->new_session). Upon conclusion of
the handshake, the finalized session is stored
in (ssl->s3->established_session). During the handshake, any requests
for the session (SSL_get_session) return a non-resumable session, to
prevent resumption of a partially filled session. Sessions should only
be cached upon the completion of the full handshake, using the resulting
established_session. The semantics of accessors on the session are
maintained mid-renego.

163f29af07 Move post-handshake message handling out of read_app_data.
This finishes getting rid of ssl_read_bytes! Now we have separate
entry-points for the various cases. For now, I've kept TLS handshake
consuming records partially. When we do the BIO-less API, I expect that
will need to change, since we won't have the record buffer available.

(Instead, the ssl3_read_handshake_bytes and extend_handshake_buffer pair
will look more like the DTLS side or Go and pull the entire record into
init_buf.)

This change opts to make read_app_data drive the message to completion
in anticipation of DTLS 1.3. That hasn't been specified, but
NewSessionTicket certainly will exist. Knowing that DTLS necessarily has
interleave seems something better suited for the SSL_PROTOCOL_METHOD
internals to drive.

It needs refining, but SSL_PROTOCOL_METHOD is now actually a half-decent
abstraction boundary between the higher-level protocol logic and
DTLS/TLS-specific record-layer and message dispatchy bits.

ec3cb3adbc Add |BN_mod_inverse_blinded| and use it in RSA blinding.
Yo dawg I herd you like blinding so I put inversion blinding in your
RSA blinding so you can randomly mask your random mask.

This improves upon the current situation where we pretend that
|BN_mod_inverse_no_branch| is constant-time, and it avoids the need to
exert a lot of effort to make a actually-constant-time modular
inversion function just for RSA blinding.

Note that if the random number generator weren't working correctly then
the blinding of the inversion wouldn't be very effective, but in that
case the RSA blinding itself would probably be completely busted, so
we're not really losing anything by relying on blinding to blind the
blinding.

9fd9580137 Remove ssl->s3->message_complete in favor of ssl->init_msg.
This was only used so we knew when we had a current message to discard
and when we didn't. With init_msg being tracked better, we can use that
instead.

As part of this, switch the V2ClientHello hack to not using
reuse_message. Otherwise we have to fill in init_msg and friends in two
places.

The next change will require that we have a better handle on the "is
there a current message" boolean.
