1444c3ace0 Add tests for auto-chaining.
Alas, wpa_supplicant relies on the auto-chaining feature, so we can't
easily remove it. Write tests for it to ensure it stays working.

These test currently do not work for TLS 1.3 because the feature is
broken in 1.3. A follow-up change will fix this.

c7df7967fa Don't chain to next_bio for buffer BIO BIO_[w]pending.
Chaining doesn't make much sense. This means we have a discontinuity
when buffer BIOs are empty. For a general filter BIO, this isn't even
meaningful. E.g., the base64 BIO's next_bio doesn't use the same units

(There's one consumer which does call BIO_pending on a base64 BIO, hits
this case, and is only working on accident, I've left it alone for this
CL until we can fix that consumer.)

The DTLS code, notably, assumes BIO_wpending to only report what's in
the buffer BIO. Ideally we'd get rid of the buffer BIO (I'll work on
this next), but, in the meantime, get the sizing right. The immediate
motivation is ssl_test using a BIO pair for DTLS doesn't work.  We've
just been lucky none of the tests have been near the MTU.

The buffer BIO is actually unused outside of the SSL stack, so this
shouldn't break external consumers. But for the base64 BIO consumer
mentioned above, I see nothing else which relies on this BIO_[w]pending
chaining.

This extension will be used to test whether
https://github.com/tlswg/tls13-spec/pull/762 is deployable against
middleboxes. For simplicity, it is mutually exclusive with 0-RTT. If
client and server agree on the extension, TLS 1.3 records will use the

17cf2cb1d2 Work around language and compiler bug in memcpy, etc.
Most C standard library functions are undefined if passed NULL, even
when the corresponding length is zero. This gives them (and, in turn,
all functions which call them) surprising behavior on empty arrays.
Some compilers will miscompile code due to this rule. See also
https://www.imperialviolet.org/2016/06/26/nonnull.html

Add OPENSSL_memcpy, etc., wrappers which avoid this problem.

720ff53d07 Trim and simplify obj_xref.c.
This avoids having more generated bits. The table is quite small,
especially so when we take out anything we don't implement. There's no
real need to do the binary search. (Exotic things like GOST, the legacy
NID_rsa and NID_dsa_2 spellings of RSA and DSA, and hash functions we
don't implement.)

Mostly this saves me from having to reimplement obj_xref.pl.
(obj_xref.pl processes nid.h, formerly obj_mac.h, so we can't just use
the existing one and still change nid.h.)

9f05de4ebb Remove the non-no_branch branch of BN_div.
Simplify the code, and in particular make |BN_div|, |BN_mod|, and
|BN_nnmod| insensitive to |BN_FLG_CONSTTIME|. This improves the
effectiveness of testing by reducing the number of branches that are
likely to go untested or less tested.

There is no performance-sensitive code that uses BN_div but doesn't
already use BN_FLG_CONSTTIME except RSA signature verification and
EC_GROUP creation. RSA signature verification, ECDH, and ECDSA
performance aren't significantly different with this change.

65fb425811 Remove version-specific cipher lists.
There are no longer any consumers of these APIs.

These were useful back when the CBC vs. RC4 tradeoff varied by version
and it was worth carefully tuning this cutoff. Nowadays RC4 is
completely gone and there's no use in configuring these anymore.

To avoid invalidating the existing ssl_ctx_api corpus and requiring it
regenerated, I've left the entries in there. It's probably reasonable
for new API fuzzers to reuse those slots.

MSAN doesn't hook |syscall| and thus doesn't know that the kernel has
filled the output buffer when |getrandom| is called.

This change tells MSAN to trust that the memory that |getrandom| writes
to has been initialised. This should avoid false-positives when code
operates on |RAND_bytes| output.

16bfff7169 Calculate Montgomery RR without division.
Get one step closer to removing the dependency on |BN_div| from most
programs. Also get one step closer to a constant-time implementation of
|BN_MONT_CTX_set|; we now "just" need to create a constant-time variant
of |BN_mod_lshift1_quick|.

Note that this version might actually increase the side channel signal,
since the variance in timing in |BN_div| is probably less than the variance
from the many conditional reductions in the new method.

On one Windows x64 machine, the speed of RSA verification using the new
version is not too different from the speed of the old code. However,
|BN_div| is generally slow on Windows x64 so I expect this isn't faster
on all platforms. Regardless, we generally consider ECDSA/EdDSA
signature verification performance to be adaquate and RSA signature
verification is much, much faster even with this change.

For RSA signing the performance is not a significant factor since
performance-sensitive applications will cache the |RSA| structure and
the |RSA| structure will cache the Montgomery contexts.

febf77190f Verify consistency of RSA keys after generation & parsing.
Call |RSA_check_key| after parsing an RSA private key in order to
verify that the key is consistent. This is consistent with ECC key
parsing, which does a similar key check.

Call |RSA_check_key| after key generation mostly as a way of
double-checking the key generation was done correctly. A similar check
was not added to |EC_KEY_generate| because |EC_KEY_generate| is used
for generating ephemeral ECDH keys, and the check would be too
expensive for that use.

-2 is really weird. On sign, it's maximal length. On verify, it actually
accepts all lengths. This sounds somewhat questionable to me, but just
document the state of the world for now. Also add a recommendation to
use -1 (match digest length) to align with TLS 1.3, tokbind, and QUIC
Crypto. Hopefully the first two is sufficient that the IETF will forever
use this option and stop the proliferation of RSA-PSS parameters.

629db8cd0c Add |SSL_get_peer_full_cert_chain|.
This function always returns the full chain and will hopefully eliminate
the need for some code in Conscrypt.

fa99197b9d perlasm/x86_64-xlate.pl: refine sign extension in ea package.
$1<<32>>32 worked fine with either 32- or 64-bit perl for a good while,
relying on quirk that [pure] 32-bit perl performed it as $1<<0>>0.  But
this apparently changed in some version past minimally required 5.10,
and operation result became 0. Yet, it went unnoticed for another while,
because most perl package providers configure their packages with
-Duse64bitint option.

364f7a6d21 Push the difference in chain semantics to the edge.
OpenSSL includes a leaf certificate in a certificate chain when it's a
client, but doesn't when it's a server. This is also reflected in the
serialisation of sessions.

This change makes the internal semantics consistent: the leaf is always
included in the chain in memory, and never duplicated when serialised.
To maintain the same API, SSL_get_peer_cert_chain will construct a copy
of the chain without the leaf if needed.

Since the serialised format of a client session has changed, an
|is_server| boolean is added to the ASN.1 that defaults to true. Thus
any old client sessions will be parsed as server sessions and (silently)
discarded by a client.
