* Unbreak Kerberos 5 authentication in telnet.nectar2003-03-061-0/+24
| | | | | | (Credential forwarding is still broken.) PR: bin/45397
* Background:nectar2003-01-292-14/+2
| | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | to do what they are supposed to: under some circumstances output data would be truncated, or the buffer would not actually be flushed (possibly leading to overflows when the caller assumes the operation succeeded). Change the semantics so that these functions ensure they complete the operation before returning. Comment out diagnostic code enabled by '-D reports' which causes an infinite recursion and an eventual crash. Patch developed with assistance from ru and assar.
