Previously, there were two copies of telnet; a non-crypto version
that lived in the usual places, and a crypto version that lived in
crypto/telnet/. The latter was built in a broken manner somewhat akin
to other "contribified" sources. This meant that there were 4 telnets
competing with each other at build time - KerberosIV, Kerberos5,
plain-old-secure and base. KerberosIV is no longer in the running, but
the other three took it in turns to jump all over each other during a
"make buildworld".
As the crypto issue has been clarified, and crypto _calls_ are not
a problem, crypto/telnet has been repo-copied to contrib/telnet,
and with this commit, all telnets are now "contribified". The contrib
path was chosen to not destroy history in the repository, and differs
from other contrib/ entries in that it may be worked on as "normal"
BSD code. There is no dangerous crypto in these sources, only a
very weak system less strong than enigma(1).
Kerberos5 telnet and Secure telnet are now selected by using the usual
macros in /etc/make.conf, and the build process is unsurprising and
less treacherous.
libdes, and functionally close enough so that we created symlinks
(libdes -> libcrypto) to help older applications. With the import of
OpenSSL 0.9.7, this is no longer true and we no longer install these
symlinks. However, systems that are upgraded may have these symlinks,
which could cause non-obvious breakage at build-time. Therefore, blow
any old symlinks away in the `afterinstall' target.
When libdes was replaced with OpenSSL's libcrypto, there were a few
interfaces that the former implemented but the latter did not. Because
some software in the base system still depended upon these interfaces,
we simply included them in our libcrypto (rnd_keys.c).
Now, finally get around to removing the dependencies on these
interfaces. There were basically two cases:
des_new_random_key -- This is just a wrapper for des_random_key, and
these calls were replaced.
des_init_random_number_generator et. al. -- A few functions were used
by the application to seed libdes's PRNG. These are not necessary
when using libcrypto, as OpenSSL internally seeds the PRNG from
/dev/random. These calls were simply removed.
Again, some of the Kerberos 4 files have been taken off the vendor
branch. I do not expect there to be future imports of KTH Kerberos 4.
can only be built with MIT Kerberos.
If we didn't define this here, then SSL-using applications would have
to define OPENSSL_NO_KRB5 themselves in order to build.
