Bump Debian version.

Some CNAMES left the value of ->uid undefined.

Since there are now special values if this, for CNAMES
to interface names, that could cause a crash
if the undefined value hit the special value.

Also ensure that the special value can't arise
when the uid is encoding the source of an F_CONFIG
record, in case there's a CNAME to it.

+	    If a domain is returned from an upstream nameserver without

+	    means that for unsigned zone (still the majority) there 
+	    is effectively no cost for having DNSSEC enabled. Of course
+	    this allows an attacker to replace a signed record with a 
+	    false unsigned record. This is addressed by the

+	    to prove that an unsigned record is legitimate, by finding  
+	    a secure proof that the zone containing the record is not
+	    signed. Doing this has costs (typically one or two extra
+	    upstream queries). It also has a nasty failure mode if
+	    dnsmasq's upstream nameservers are not DNSSEC capable. 
+	    Without --dnssec-check-unsigned using such an upstream

+	    DNSSEC-ignorant upstream server, _all_ queries will fail.
+
+	    Note that DNSSEC requires that the local time is valid and 
+	    accurate, if not then DNSSEC validation will fail. NTP 
+	    should be running. This presents a problem for routers
+	    without a battery-backed clock. To set the time needs NTP 
+	    to do DNS lookups, but lookups will fail until NTP has run.
+	    To address this, there's a flag, --dnssec-no-timecheck

+Dnsmasq provides network infrastructure for small networks: DNS, DHCP, router advertisement and network boot. It is designed to be 
+lightweight and have a small footprint, suitable for resource constrained routers and firewalls. It has also been widely used 
+for tethering on smartphones and portable hotspots, and to support virtual networking in virtualisation frameworks.
+Supported platforms include Linux (with glibc and uclibc), Android, *BSD, and Mac OS X. Dnsmasq is included in most
+Linux distributions and the ports systems of FreeBSD, OpenBSD and NetBSD. Dnsmasq provides full IPv6 support.
 
-Dnsmasq is a lightweight, easy to configure DNS forwarder and DHCP
- server. It is designed to provide DNS and, optionally, DHCP, to a 
- small network. It can serve the names of local machines which are 
- not in the global DNS. The DHCP server integrates with the DNS 
- server and allows machines with DHCP-allocated addresses
- to appear in the DNS with names configured either in each host or
- in a central configuration file. Dnsmasq supports static and dynamic 
- DHCP leases and BOOTP/TFTP/PXE for network booting of diskless machines.
 <P>

+The DNS subsystem provides a local DNS server for the network, with forwarding of all query types to upstream recursive DNS servers and

-Dnsmasq can be configured to automatically pick up the addresses of

-On IPv6-enabled boxes, dnsmasq can both talk to upstream servers via IPv6
