mrg 4bc6feceb6 end the argument list to exec*(3) with a NULL instead of a bare '0', as 
the latter isn't a pointer context in these varargs functions.

rpaulo de8db47547 Add support for RFC 3542 Adv. Socket API for IPv6 (which obsoletes 2292). 
* RFC 3542 isn't binary compatible with RFC 2292.
* RFC 2292 support is on by default but can be disabled.
* update ping6, telnet and traceroute6 to the new API.

From the KAME project (www.kame.net).

heas 209ebbab46 - deal with a dead tty in ttyflush() by cleaning-up and exiting instead of 
returning a failure code and processing that all the way up the stack.
- deal with a dead peer similarly and do it without setjmp/longjmp() (at
  christos' request).

These fix bin/20304 and my own observations when the remote abruptly closes
the connection.

mjl 6c2663f7dd Fix possible buffer overruns. From OpenBSD, but without breaking stuff. 2001-01-03 12:41:00 +00:00
thorpej 5c099b14c1 Bring the telnet situation back into better shape. Specifically, 
pull in just about all of the differences from the crypto-us telnet
suite (which includes Kerberos 4 and connection encryption support).
Also bring in the Kerberos 5 support from the Heimdal telnet, and
frob a little so that it can work with the non-Heimdal telnet suite.

There is still some work left to do, specifically:
- Add Heimdal's ticket forwarding support to the Berkeley Kerberos 4
  module.
- Add connection encryption support to the Heimdal Kerberos 5
  module.  Hints on this can be taken from the MIT Kerberos 5
  module which still exists in crypto-us.

However, even with the shortcomings listed above, this is a
better situation than using the stock Heimdal telnet suite,
which does not understand the IPSec policy stuff, and is also
based on much older code which contains bugs that we have already
fixed in the NetBSD sources.

itojun 1e75e9ee55 remove setuid(getuid()). they are unnecessary as noone is going to 
setuid telnet(1).

i'm not sure why it is here (maybe someone reused this code from
other setuid'ed program, or someone cut-and-pasted the code from
somewhere else?), it was from revision 1.1 (= 4.4BSD).

briefly discussed in: tech-net?
