32c869ffab Ensure EVP_PKEY_set1_DH detects X9.42 keys
OpenSSL supports both PKCS#3 and X9.42 DH keys. By default we use PKCS#3
keys. The function `EVP_PKEY_set1_DH` was assuming that the supplied DH
key was a PKCS#3 key. It should detect what type of key it is and assign
the correct type as appropriate.

742ccab318 Deprecate most of debug-memory
Fixes #8322

The leak-checking (and backtrace option, on some platforms) provided
by crypto-mdebug and crypto-mdebug-backtrace have been mostly neutered;
only the "make malloc fail" capability remains.  OpenSSL recommends using
the compiler's leak-detection instead.

The OPENSSL_DEBUG_MEMORY environment variable is no longer used.
CRYPTO_mem_ctrl(), CRYPTO_set_mem_debug(), CRYPTO_mem_leaks(),
CRYPTO_mem_leaks_fp() and CRYPTO_mem_leaks_cb() return a failure code.
CRYPTO_mem_debug_{malloc,realloc,free}() have been removed.  All of the
above are now deprecated.

46994f7163 Add better support for using deprecated symbols internally
OPENSSL_SUPPRESS_DEPRECATED only does half the job, in telling the
deprecation macros not to add the warning attribute.  However, with
'no-deprecated', the symbols are still removed entirely, while we
might still want to use them internally.

The solution is to permit <openssl/opensslconf.h> macros to be
modified internally, such as undefining OPENSSL_NO_DEPRECATED in this
case.

However, with the way <openssl/opensslconf.h> includes
<openssl/macros.h>, that's easier said than done.  That's solved by
generating <openssl/configuration.h> instead, and add a new
<openssl/opensslconf.h> that includes <openssl/configuration.h> as
well as <openssl/macros.h>, thus allowing to replace an inclusion of
<openssl/opensslconf.h> with this:

    #include <openssl/configuration.h>

    #undef OPENSSL_NO_DEPRECATED
    #define OPENSSL_SUPPRESS_DEPRECATED

    #include <openssl/macros.h>

Or simply add the following prior to any other openssl inclusion:

    #include <openssl/configuration.h>

    #undef OPENSSL_NO_DEPRECATED
    #define OPENSSL_SUPPRESS_DEPRECATED

Note that undefining OPENSSL_NO_DEPRECATED must never be done by
applications, since the symbols must still be exported by the
library.  Internal test programs are excempt of this rule, though.

97ba39547d test/namemap_internal_test.c: use "cookie" instead of "foo"...
... in test_namemap()

Because tests may sometimes run in random order (subject of the
environment variable OPENSSL_TEST_RAND_ORDER being defined), and we're
dealing with the global namemap, each test must use names that are
globally unique for that test.  Unfortunately, we used "foo" in two of
them, which might lead to surprising results.

2ff16afc17 Optimize AES-ECB mode in OpenSSL for both aarch64 and aarch32
Aes-ecb mode can be optimized by inverleaving cipher operation on
several blocks and loop unrolling. Interleaving needs one ideal
unrolling factor, here we adopt the same factor with aes-cbc,
which is described as below:
    If blocks number > 5, select 5 blocks as one iteration,every
    loop, decrease the blocks number by 5.
    If 3 < left blocks < 5 select 3 blocks as one iteration, every
    loop, decrease the block number by 3.
    If left blocks < 3, treat them as tail blocks.
Detailed implementation will have a little adjustment for squeezing
code space.
With this way, for small size such as 16 bytes, the performance is
similar as before, but for big size such as 16k bytes, the performance
improves a lot, even reaches to 100%, for some arches such as A57,
the improvement  even exceeds 100%. The following table will list the
encryption performance data on aarch64, take a72 and a57 as examples.
Performance value takes the unit of cycles per byte, takes the format
as comparision of values. List them as below:

DECLARE_STACK_OF was renamed to DEFINE_STACK_OF in commit 8588571.
Expanded the only use of TYPEDEF_{D2I,I2D,D2I2D}_OF, so that they can
easily be removed in a future release

ea7a952c8a test/memleaktest.c: Modify for use with address/leak sanitizer
Detects if leak sanitizing is on, and directs the exit code accordingly.

Note that this program is designed to fail when leaking, as that's
expected, so to make it easy for wrapper scripts, we also make it look
like it fails when sanitizing isn't on.

22c22369bc Use leak sanitizer instead of internal mdebug to check for memory leaks
The leak sanitizer gives better reports (complete stack traces) and
works as a wrapper around the application instead of relying on
cooperative enabling and disabling calls (which are too easy to get
unbalanced).

Summary:
U64 is too common name for macro, being in public header sha.h it
conflicts with other projects (WAVM in my case). Moving macro from
public header to the only .c file using it.

8736f95381 Improve the overflow handling in rsaz_512_sqr
We have always a carry in %rcx or %rbx in range 0..2
from the previous stage, that is added to the result
of the 64-bit square, but the low nibble of any square
can only be 0, 1, 4, 9.

Therefore one "adcq $0, %rdx" can be removed.
Likewise in the ADX code we can remove one
"adcx %rbp, $out" since %rbp is always 0, and carry is
also zero, therefore that is a no-op.

8c6f86c7c5 Fix an overflow bug in rsaz_512_sqr
There is an overflow bug in the x64_64 Montgomery squaring procedure used in
exponentiation with 512-bit moduli. No EC algorithms are affected. Analysis
suggests that attacks against 2-prime RSA1024, 3-prime RSA1536, and DSA1024 as a
result of this defect would be very difficult to perform and are not believed
likely. Attacks against DH512 are considered just feasible. However, for an
attack the target would have to re-use the DH512 private key, which is not
recommended anyway. Also applications directly using the low level API
BN_mod_exp may be affected if they use BN_FLG_CONSTTIME.
