Dnsmasq 2.56 is now available, download it from
Changes WRT the previous version are below.
Add a patch to allow dnsmasq to get interface names right in
a Solaris zone. Thanks to Dj Padzensky for this.
Improve data-type parsing heuristics so that
treats the value as a string and not an IP address.
Thanks to Clemens Fischer for spotting that.
Add IPv6 support to the TFTP server. Many thanks to Jan
'RedBully' Seiffert for the patches.
Log DNS queries at level LOG_INFO, rather then
LOG_DEBUG. This makes things consistent with DHCP
logging. Thanks to Adam Pribyl for spotting the problem.
Ensure that dnsmasq terminates cleanly when using
--syslog-async even if it cannot make a connection to the
Add --add-mac option. This is to support currently
experimental DNS filtering facilities. Thanks to Benjamin
Petrin for the orignal patch.
Fix bug which meant that tags were ignored in dhcp-range
configuration specifying PXE-proxy service. Thanks to
Cristiano Cumer for spotting this.
Raise an error if there is extra junk, not part of an
option, on the command line.
Flag a couple of log messages in cache.c as coming from
the DHCP subsystem. Thanks to Olaf Westrik for the patch.
Omit timestamps from logs when a) logging to stderr and
b) --keep-in-forground is set. The logging facility on the
other end of stderr can be assumned to supply them. Thanks
to John Hallam for the patch.
Don't complain about strings longer than 255 characters in
--txt-record, just split the long strings into 255
character chunks instead.
Fix crash on double-free. This bug can only happen when
dhcp-script is in use and then only in rare circumstances
triggered by high DHCP transaction rate and a slow
script. Thanks to Ferenc Wagner for finding the problem.
Only log that a file has been sent by TFTP after the
transfer has completed succesfully.
A good suggestion from Ferenc Wagner: extend
the --domain option to allow this sort of thing:
which automatically creates
Tighten up syntax checking of hex contants in the config
file. Thanks to Fred Damen for spotting this.
Add dnsmasq logo/icon, contributed by Justin Swift. Many
thanks for that.
Never cache DNS replies which have the 'cd' bit set, or
which result from queries forwarded with the 'cd' bit
set. The 'cd' bit instructs a DNSSEC validating server
upstream to ignore signature failures and return replies
anyway. Without this change it's possible to pollute the
dnsmasq cache with bad data by making a query with the
'cd' bit set and subsequent queries would return this data
without its being marked as suspect. Thanks to Anders
Kaseorg for pointing out this problem.
Add --proxy-dnssec flag, for compliance with RFC
4035. Dnsmasq will now clear the 'ad' bit in answers
returned from upstream validating nameservers unless this
option is set.
Allow a filename of "-" for --conf-file to read
stdin. Suggestion from Timothy Redaelli.
Rotate the order of SRV records in replies, to provide
round-robin load balancing when all the priorities are
equal. Thanks to Peter McKinney for the suggestion.
so that it doesn't log all queries to a file by
default. Thanks again to Peter McKinney.
By default, setting an IPv4 address for a domain but not
an IPv6 address causes dnsmasq to return
an NODATA reply for IPv6 (or vice-versa). So
--address=/google.com/22.214.171.124 stops IPv6 queries for
*google.com from being forwarded. Make it possible to
override this behaviour by defining the sematics if the
same domain appears in both --server and --address.
In that case, the --address has priority for the address
family in which is appears, but the --server has priority
of the address family which doesn't appear in --adddress
will return 126.96.36.199 for IPv4 queries for *.google.com but
forward IPv6 queries to the normal upstream nameserver.
Similarly when setting an IPv6 address
only this will allow forwarding of IPv4 queries. Thanks to
William for pointing out the need for this.
Allow more than one --dhcp-optsfile and --dhcp-hostsfile
and make them understand directories as arguments in the
same way as --addn-hosts. Suggestion from John Hanks.
Ignore rebinding requests for leases we don't know
about. Rebind is broadcast, so we might get to overhear a
request meant for another DHCP server. NAKing this is
wrong. Thanks to Brad D'Hondt for assistance with this.
Fix cosmetic bug which produced strange output when
dumping cache statistics with some configurations. Thanks
to Fedor Kozhevnikov for spotting this.
