uucp bug

[utzoo!decvax!ucbvax!mhtsa!harpo!floyd!cmcl2!salkind]

In conn.c, if you fail to login to a machine, the (dialout) line file
descriptor will not be closed.  Therefore the next open on the line will
fail (because the line is set for exclusive access).

This problem can show up if you execute (not as root)
	uucico -r1

The fix is a one line addition to the routine login():


*** conn.c	Mon Mar 22 16:25:50 1982
--- conn.c.old	Mon Mar 22 16:27:42 1982

  			if (altern == NULL) {
  				logent("LOGIN", "FAILED");
- 				close(fn);
  				return(FAIL);
  			}
  			want = index(altern, '-');

--- 531,536 -----
  				break;

  				logent("LOGIN", "FAILED");
  				return(FAIL);

  			want = index(altern, '-');
