I have not tried to use all the new stuff in dnsmasq 2.66 as yet, but I figure
that cero's users are not aware of new capability #1 here - there is also some
support for filtering out A records and yet publishing AAAA records in
the public DNS, also.
Anyway, current release of cero has a beta of 2.66, next release will
have the final, and if anyone can clue me up on how to safely open up port
53 again, have a NS delegation, and do the AAAA thing, that would be cool.
(reverse lookups work?)
Add the ability to act as an authoritative DNS
server. Dnsmasq can now answer queries from the wider 'net
with local data, as long as the correct NS records are set
up. Only local data is provided, to avoid creating an open
DNS relay. Zone transfer is supported, to allow secondary
servers to be configured.
Add "constructed DHCP ranges" for DHCPv6. This is intended
for IPv6 routers which get prefixes dynamically via prefix
delegation. With suitable configuration, stateful DHCPv6
and RA can happen automatically as prefixes are delegated
and then deprecated, without having to re-write the
dnsmasq configuration file or restart the daemon. Thanks to
Steven Barth for extensive testing and development work on
Fix crash on startup on Solaris 11. Regression probably
introduced in 2.61. Thanks to Geoff Johnstone for the
Add code to make behaviour for TCP DNS requests that same
as for UDP requests, when a request arrives for an allowed
address, but via a banned interface. This change is only
active on Linux, since the relevant API is missing (AFAIK)
on other platforms. Many thanks to Tomas Hozza for
spotting the problem, and doing invaluable discovery of
the obscure and undocumented API required for the solution.
Don't send the default DHCP option advertising dnsmasq as
the local DNS server if dnsmasq is configured to not act
as DNS server, or it's configured to a non-standard port.
Add DNSMASQ_CIRCUIT_ID, DNSMASQ_SUBCRIBER_ID,
DNSMASQ_REMOTE_ID variables to the environment of the
lease-change script (and the corresponding Lua). These hold
information inserted into the DHCP request by a DHCP relay
agent. Thanks to Lakefield Communications for providing a
bounty for this addition.
Fixed crash, introduced in 2.64, whilst handling DHCPv6
information-requests with some common configurations.
Thanks to Robert M. Albrecht for the bug report and
chasing the problem.
Add --ipset option. Thanks to Jason A. Donenfeld for the
Don't erroneously reject some option names in --dhcp-match
options. Thanks to Benedikt Hochstrasser for the bug report.
Allow a trailing '*' wildcard in all interface-name
configurations. Thanks to Christian Parpart for the patch.
Handle the situation where libc headers define
SO_REUSEPORT, but the kernel in use doesn't, to cope with
the introduction of this option to Linux. Thanks to Rich
Felker for the bug report.
Update Polish translation. Thanks to Jan Psota.
Fix crash if the configured DHCP lease limit is
reached. Regression occurred in 2.61. Thanks to Tsachi for
the bug report.
Update the French translation. Thanks to Gildas le Nadan.
