[Dnsmasq-discuss] dnsmasq-2.21 released.

[Simon Kelley]

I just released dnsmasq-2.21. This addresses most of the 
issues/suggestions/patches which have come up in this list over the past 
couple of months. It even adds DHCP support for IP-alias/interfaces with 
more than one address.

Get it from http://www.thekelleys.org.uk/dnsmasq/dnsmasq-2.21.tar.gz

The complete changelog entry is appended below.


Enjoy,


Simon.



             Improve handling of SERVFAIL and REFUSED errors. Receiving
             these now initiates search for a new good server, and a
             server which returns them is not a candidate as a good
             server. Thanks to Istvan Varadi for pointing out the
             problem.

             Tweak the time code in BROKEN_RTC mode.

             Sanity check lease times in dhcp-range and dhcp-host
             configurations and force them to be at least two minutes
             (120s) leases shorter than a minute confuse some clients,
             notably Apple MacOS X. Rory Campbell-Lange found this
             problem.

             Only warn once about an upstream server which is refusing to
             do recursive queries.

             Fix DHCP address allocation problem when netid tags are in
             use. Thanks to Will Murnane for the bug report and
             subsequent testing.

             Add an additional data section to the reply for MX and SRV
             queries. Add support for DNS TXT records. Thanks to Robert
             Kean and John Hampton for prompts and testing of these.

             Apply address rewriting to records in the additional data
             section of DNS packets. This makes things like MX records
	    work with the alias function. Thanks to Chad Skeeters for
             pointing out the need for this.

             Added support for quoted strings in config file.

             Detect and defeat cache-poisoning attacks which attempt to
             send (malicious) answers to questions we didn't
             send. These are ignored now even if the attacker manages
             to guess a random query-id.

             Provide DHCP support for interfaces with multiple IP
             addresses or aliases. This in only enabled under Linux.
             See the FAQ entry for details.

             Revisit the MAC-address and client-id matching code to
             provide saner behaviour with PXE boots, where some
             requests have a client-id and some don't.

             Fixed off-by-one buffer overflow in lease file reading
             code. Thanks to Rob Holland for the bug report.

             Added wildcard matching for MAC addresses in dhcp-host
             options. A sensible suggestion by Nathaniel McCallum.
