Author: ed Date: Sun Jan 17 17:52:35 2010 New Revision: 202500 URL: http://svn.freebsd.org/changeset/base/202500 Log: Fix a regression that was introduced in r191882. I changed login_tty() to only work when the application is not a session leader yet. This works fine for applications in the base system, but it turns out various applications call this function after daemonizing, which means they already use their own session. If setsid() fails, just call tcsetsid() on the current session. tcsetsid() will already perform proper security checks.
