Clean up no-mdc2 default no-patent cruft?

[William A. Rowe, Jr.]

This patent expired 2 years ago, it seems 1.0.0 is a good time to
get this fixed... at least if it remains default-disabled, then the
justification should be noted (no longer patented but perhaps some
deprecated commentary?)

I think the changes are limited to the lines below...

README
--
  The MDC2 algorithm is patented by IBM.

FAQ

  You can configure OpenSSL so as not to use IDEA, MDC2 and RC5 by using
  ./config no-idea no-mdc2 no-rc5
[...]
  FYI: Patent numbers and expiry dates of US patents:
  MDC-2: 4,908,861 13/03/2007

  # This is what $depflags will look like with the above defaults

-DOPENSSL_NO_STORE;


Miscellany
--
from util/mk1mf.pl
no-patents =
[\$no_rc2, \$no_rc4, \$no_rc5, \$no_idea, \$no_rsa],

Why RSA (expired in 2000)?  How are RC2, RC4 in this list.  Not patents.
Trademarks?

Also it seems odd this is recognized by mk1mf.pl - wrong place.  Should be
set up in Configure.  No?

Somewhere, perhaps add;

MDC2 was covered by a US patent issued to IBM which expired in March 2007.

[PATCH] Add z/OS compilation options with xlc

[Amul Shah]

Hello,
I did a quick search of the openssl.org pages for patch submission
guidelines.  I didn't find one, so please excuse any oddities from my end.

This patch adds z/OS compilations options to the Configure script for
openssl 0.9.8k.

My setup:

I compiled openssl with xlc (V1.10)
and ran the openssl self checks on z/OS V1R10.

I compiled and ran the openssl self checks on z/OS R10 with the ICSF
(encryption hardware and /dev/random enabled by IBM support staff). 
Most of the self checks passed, there was a glaring failure for DES.

The new build options are as follows:
- OS390-Unix32-ascii
Compile openssl as a 31 bit ASCII enabled with shared libraries
- OS390-Unix64-ascii
Compile openssl as a 64 bit ASCII enabled with shared libraries
- OS390-Unix32
Compile openssl as a 31 bit app with shared libraries (uses the platform
native encoding EBCDIC)
- OS390-Unix64
Compile openssl as a 64 bit app with shared libraries (uses the platform
native encoding EBCDIC)

MD[2,4,5]_[Final,Init,Update]

[Mizas, Timothy]

Hi,
I've been trying to find the source for the MD[2,4,5]_[Final, Init, Update] 
functions. The Linux kernel has md[4,5]_[final, init, update], but not only is 
it missing 2, it is in lower case and seems to take different arguments than 
openssl passes to these functions. Where can I find the source for these 
functions?

Thanks,
Tim

there was a similar thread on openssl-users yesterday, starting with
