Add tests for have_precompute_mult for the optimised curves (nistp224,
nistp256 and nistp521) if present
Reviewed-by: Richard Levitte <levitte@openssl.org>
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.

The function DH_check_pub_key() was missing some return value checks in
some calls to BN functions.
RT#4278
Reviewed-by: Andy Polyakov <appro@openssl.org>
A new return value for DH_check_pub_key was recently added:
DH_CHECK_PUBKEY_INVALID. As this is a flag which can be ORed with other
return values it should have been set to the value 4 not 3.

This extends the existing async functionality to SSL_shutdown(), i.e.
SSL_shutdown() can now casuse an SSL_ERROR_WANT_ASYNC error to be returned
from SSL_get_error() if async mode has been enabled.

These tests are not built, and only usable as hand-tests so not

Following on from the previous commit, add a test to ensure that
DH_compute_key correctly fails if passed a bad y such that:
y^q (mod p) != 1
Reviewed-by: Viktor Dukhovni <viktor@openssl.org>
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)
And also make D_ENCRYPT macro more clear (@appro)
This is done in consultation with Andy.

It seems that Test::More doesn't like 0 tests, a line like this raises
an error and stops the recipe entirely:
plan tests => 0;
So we need to check for 0 tests beforehand and skip the subtest
explicitely in that case.

Also removes the make variable SHARED_LIBS_LINK_EXTS, only used by
the clean-shared target.
When shared library linking was moved to the separate Makefile.shared
in commit 30afcc072a, this target was
skipped. Prior to that commit, clean-shared was invoked as a
dependency of build-shared, but afterward it was no longer referenced
anywhere in the tree.
Instead of porting the functionality over to Makefile.shared, just
remove it entirely, as it appears to be unused.

Since we're building some of our perl scripts and the result might not
end up in apps/ (*), we may need to treat them like the compile
programs we use for testing.
This introduces perlapp() and perltest(), which behave like app() and
test(), but will add the perl executable in the command line.

(*) For example, with a mk1mf build, the result will end up in $(BIN_D)

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 */

It is time for Makefile.org to fold into the new regime and have a run
through util/dofile.pl. This forces some information out of there and
into Configure, which isn't a bad thing, it makes Configure
increasingly the center of build information, which is as it should
be.
A few extra defaults were needed in the BASE template to get rid of
warnings about missing values.
