commit fd648907e46017d46c367f59c62d0b0395830903
Author: Simon McVittie <http://smcv.pseudorandom.co.uk/>
Date:   2009-01-04 19:35:51 +0000

    Allow root to send messages to all the system tools backends, so they work even when CVE-2008-4311 has been fixed.
    
    Also disallow normal user access by destination, not by interface (fd.o #18961).
