During precomputation if the group given is well known then we memcpy a
well known precomputation. However we go the wrong label in the code and
don't store the data properly. Consequently if we call have_precompute_mult
the data isn't there and we return 0.

Historically OpenSSL only ever generated DH parameters based on "safe"
primes. More recently (in version 1.0.2) support was provided for
generating X9.42 style parameter files such as those required for RFC
5114 support. The primes used in such files may not be "safe". Where an
application is using DH configured with parameters based on primes that
are not "safe" then an attacker could use this fact to find a peer's
private DH exponent. This attack requires that the attacker complete
multiple handshakes in which the peer uses the same DH exponent.
A simple mitigation is to ensure that y^q (mod p) == 1

Many options for supporting optimizations for legacy crypto on legacy
platforms have been removed. This simplifies the source code and
does not really penalize anyone.
DES_PTR (always on)
DES_RISC1, DES_RISC2 (always off)
DES_INT (always 'unsigned int')
DES_UNROLL (always on)
BF_PTR (always on) BF_PTR2 (removed)
MD2_CHAR, MD2_LONG (always 'unsigned char')
IDEA_SHORT, IDEA_LONG (always 'unsigned int')
RC2_SHORT, RC2_LONG (always 'unsigned int')
RC4_LONG (only int and char (for assembler) are supported)
RC4_CHUNK (always long), RC_CHUNK_LL (removed)
RC4_INDEX (always on)

This was done by the following
find . -name '*.[ch]' | /tmp/pl
where /tmp/pl is the following three-line script:
print unless $. == 1 && m@/\* .*\.[ch] \*/@;
close ARGV if eof; # Close file to reset $.
And then some hand-editing of other files.

Now that we're using templates, we should warn people not to edit the
resulting file. We do it through util/dofile.pl, which is enhanced
with an option to tell what file it was called from. We also change
the calls so the template files are on the command line instead of
being redirected through standard input. That way, we can display
something like this (example taken from include/openssl/opensslconf.h):
/* WARNING: do not edit! */
/* Generated by Configure from include/openssl/opensslconf.h.in */

The turn has come to have crypto/opensslconf.h.in get run through
util/dofile.pl. The consequence is that a large number of variables
get moved to the %config table.
Also, the string variables $openssl_*, which were populated with cpp
lines, all being of the form "#define SOMETHING", were converted into
ARRAY refs in %config values, containing just the list of macros to be
defined.

Returning untrusted is enough for for full chains that end in
self-signed roots, because when explicit trust is specified it
suppresses the default blanket trust of self-signed objects.
But for partial chains, this is not enough, because absent a similar
trust-self-signed policy, non matching EKUs are indistinguishable
from lack of EKU constraints.
Therefore, failure to match any trusted purpose must trigger an
explicit reject.

When DANE-EE(3) matches or either of DANE-EE/PKIX-EE fails, we don't
build a chain at all, but rather succeed or fail with just the leaf
certificate. In either case also check for Suite-B violations.
As unlikely as it may seem that anyone would enable both DANE and
Suite-B, we should do what the application asks.

It seems risky in the context of cross-signed certificates when the
same certificate might have multiple potential issuers. Also rarely
used, since chains in OpenSSL typically only employ self-signed
trust-anchors, whose self-signatures are not checked, while untrusted
certificates are generally ephemeral.
