Update to new upstream release 2.52. Changelog excerpt below the approval.
Approved by: miwi (mentor)
Upstream changelog excerpt (omitting Linux, Solaris and MacOS X specifics):
[...] Re-read the set of network interfaces when re-loading /etc/resolv.conf
if --bind-interfaces is not set. This handles the case that loopback
interfaces do not exist when dnsmasq is first started.
Tweak the PXE code to support port 4011. This should reduce broadcasts and
make things more reliable when other servers are around. It also improves
inter-operability with certain clients.
Make a pxe-service configuration with no filename or boot service type legal:
this does a local boot. eg. pxe-service=x86PC, "Local boot"
Be more conservative in detecting "A for A" queries. Dnsmasq checks if the
name in a type=A query looks like a dotted-quad IP address and answers the
query itself if so, rather than forwarding it. Previously dnsmasq relied in
the library function inet_addr() to convert addresses, and that will accept
some things which are confusing in this context, like 1.2.3 or even just
1234. Now we only do A for A processing for four decimal numbers delimited by
dots.
[...]
Increased the default limit on number of leases to 1000 (from 150). This is
mainly a defence against DoS attacks, and for the average "one for two class
C networks" installation, IP address exhaustion does that just as well.
Making the limit greater than the number of IP addresses available in such an
installation removes a surprise which otherwise can catch people out.
Removed extraneous trailing space in the value of the DNSMASQ_TIME_REMAINING
DNSMASQ_LEASE_LENGTH and DNSMASQ_LEASE_EXPIRES environment variables. Thanks
to Gildas Le Nadan for spotting this.
Provide the network-id tags for a DHCP transaction to the lease-change script
in the environment variable DNSMASQ_TAGS. A good suggestion from Gildas Le
Nadan.
Add support for RFC3925 "Vendor-Identifying Vendor Options". The syntax looks
like this:
--dhcp-option=vi-encap:<enterprise number>, .........
Add support to --dhcp-match to allow matching against RFC3925
"Vendor-Identifying Vendor Classes". The syntax looks like this:
--dhcp-match=tag,vi-encap<enterprise number>, <value>
Add some application specific code to assist in implementing the Broadband
forum TR069 CPE-WAN specification. The details are in contrib/CPE-WAN/README
Increase the default DNS packet size limit to 4096, as recommended by RFC5625
section 4.4.3. This can be reconfigured using --edns-packet-max if needed.
Thanks to Francis Dupont for pointing this out.
Rewrite query-ids even for DNSSEC signed packets, since this is allowed by
RFC5625 section 4.5.
[...]
Fix link error when including Dbus but excluding DHCP.
Thanks to Oschtan for the bug report.
