Generate an error when configured with a CNAME loop,
rather than a crash. Thanks to George Metz for
spotting this problem.
Calculate the length of TFTP error reply packet
correctly. This fixes a problem when the error
message in a TFTP packet exceeds the arbitrary
limit of 500 characters. The message was correctly
truncated, but not the packet length, so
extra data was appended. This is a possible
security risk, since the extra data comes from
a buffer which is also used for DNS, so that
previous DNS queries or replies may be leaked.
Fix logic error in Linux netlink code. This could
cause dnsmasq to enter a tight loop on systems
with a very large number of network interfaces.
Fix problem with --dnssec-timestamp whereby receipt
of SIGHUP would erroneously engage timestamp checking.
Bump zone serial on reloading /etc/hosts and friends
when providing authoritative DNS.
Handle v4-mapped IPv6 addresses sanely in --synth-domain.
These have standard representation like ::ffff:1.2.3.4
and are now converted to names like
<prefix>--ffff-1-2-3-4.<domain>
Handle binding upstream servers to an interface
(--server=1.2.3.4@eth0) when the named interface
is destroyed and recreated in the kernel.
Allow wildcard CNAME records in authoritative zones.
For example --cname=*.example.com,default.example.com

When building DBus support, install the config file for DBus
Notable Changes from 2.55:
IPv6 interface fixes
Fixed an invalid server id of 0.0.0.0 being sent in some situations
Correctly return NODATA for an AAAA query to a CNAME with only an A
Fixed a bug with some truncated TFTP files
Support IPv6 scope ids in resolv.conf
dhowland.
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 for network booting of diskless machines.
