engines/ccgost/gost89.h: make word32 defintion unconditional.
Original definition depended on __LONG_MAX__ that is not guaranteed to
be present. As we don't support platforms with int narrower that 32 bits
it's appropriate to make defition inconditional.
DTLS/SCTP requires DATA and FORWARD-TSN chunks to be protected with
SCTP-AUTH. It is checked if this has been activated successfully for
the local and remote peer. Due to a bug, however, the
gauth_number_of_chunks field of the authchunks struct is missing on
FreeBSD, and was therefore not considered in the OpenSSL implementation.
This patch sets the corresponding pointer for the check correctly
whether or not this bug is present.
With DTLS/SCTP the SCTP extension SCTP-AUTH is used to protect DATA and
FORWARD-TSN chunks. The key for this extension is derived from the
master secret and changed with the next ChangeCipherSpec, whenever a new
key has been negotiated. The following Finished then already uses the
new key. Unfortunately, the ChangeCipherSpec and Finished are part of
the same flight as the ClientKeyExchange, which is necessary for the
computation of the new secret. Hence, these messages are sent
immediately following each other, leaving the server very little time to
compute the new secret and pass it to SCTP before the finished arrives.
So the Finished is likely to be discarded by SCTP and a retransmission
becomes necessary. To prevent this issue, the Finished of the client is
still sent with the old key.
While the gmt_unix_time record was added in an ostensible attempt to
mitigate the dangers of a bad RNG, its presence leaks the host's view
of the current time in the clear. This minor leak can help
fingerprint TLS instances across networks and protocols... and what's
worse, it's doubtful thet the gmt_unix_time record does any good at
all for its intended purpose, since:
* It's quite possible to open two TLS connections in one second.
* If the PRNG output is prone to repeat itself, ephemeral
handshakes (and who knows what else besides) are broken.
Removing RSA+MD5 from the default signature algorithm list
prevents its use by default.
If a broken implementation attempts to use RSA+MD5 anyway the sanity
checking of signature algorithms will cause a fatal alert.

MIPS assembly pack: get rid of deprecated instructions.
Latest MIPS ISA specification declared 'branch likely' instructions
obsolete. To makes code future-proof replace them with equivalent.
(cherry picked from commit 0c2adb0a9be76da8de9bbfd5377215f71711a52e)
Add X9.42 DH KDF. Move sharedinfo generation code to CMS library as the
same structure is used by DH and ECDH.
Move ASN1_OBJECT typedef to ossl_typ.h so it can be picked up by dh headers
without the need to use ASN1.
(cherry picked from commit dc1ce3bc64845d16314af1f11acf5384e4ae9b34)
Return correct enveloped data type in ASN1 methods.
For RSA and DSA keys return an appropriate RecipientInfo type. By setting
CMS_RECIPINFO_NONE for DSA keys an appropriate error is returned if
an attempt is made to use DSA with enveloped data.

Check and set AlgorithmIdenfier parameters for key wrap algorithms.
Currently these just set parameters to NULL.
(cherry picked from commit e61f5d55bc0072e75023be8971ae6e849643f466)
Add support for ECDH in enveloped data. The CMS ctrls for the EC ASN1
method decode/encode the appropriate parameters from the CMS ASN1 data
and send appropriate data to the EC public key method.

Add hooks to support key agreement recipient info type (KARI) using
algorithm specific code in the relevant public key ASN1 method.

Add support for custom public key parameters in the cms utility using
the -keyopt switch. Works for -sign and also -encrypt if -recip is used.

Add OAEP ctrls to retrieve MD and label. Return errors if

Extend OAEP support. Generalise the OAEP padding functions to support

Add support for customisation of CMS handling of signed and enveloped

This will provide support for RSA-PSS and RSA-OAEP but could also be

Add code to support GCM an CCM modes in evp_test. On encrypt this
