src/libexec/telnetd/utility.c, branch upstream/10.4.0

Very big makeover in the way telnet, telnetd and libtelnet are built.

2003-07-16T20:59:15Z

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.

Mrege from crypto telnet with "make unifdef". This gets a bunch of

$FreeBSD$ tags and some debug variable safety belts.

After running a "make unifdef", commit the resultant diffs.

This code is now a complete sunset of the crypto (master) code.

Feature merging and diff reduction between this code and crypto telnet.

Also remove conditional (AUTHENTICATION) code as we have never compiled it here, and it is doubtful that it even works in this scenario.

with telnetd. This should really be done with a positive filter - i.e. only allow through a configured list of variables. Also do some buffer-safety cleanups while I'm here - I don't think these are exploitable.
