Update 2.67 to 2.72

-------------------
version 2.72
            Add ra-advrouter mode, for RFC-3775 mobile IPv6 support.

	    Add support for "ipsets" in *BSD, using pf. Thanks to
	    Sven Falempim for the patch.

	    Fix race condition which could lock up dnsmasq when an
	    interface goes down and up rapidly. Thanks to Conrad
	    Kostecki for helping to chase this down.

	    Add DBus methods SetFilterWin2KOption and SetBogusPrivOption
	    Thanks to the Smoothwall project for the patch.

	    Fix failure to build against Nettle-3.0. Thanks to Steven
	    Barth for spotting this and finding the fix.

	    When assigning existing DHCP leases to intefaces by comparing
	    networks, handle the case that two or more interfaces have the
	    same network part, but different prefix lengths (favour the
	    longer prefix length.) Thanks to Lung-Pin Chang for the
	    patch.

	    Add a mode which detects and removes DNS forwarding loops, ie
	    a query sent to an upstream server returns as a new query to
	    dnsmasq, and would therefore be forwarded again, resulting in
	    a query which loops many times before being dropped. Upstream
	    servers which loop back are disabled and this event is logged.
	    Thanks to Smoothwall for their sponsorship of this feature.

	    Extend --conf-dir to allow filtering of files. So
	    --conf-dir=/etc/dnsmasq.d,\*.conf
	    will load all the files in /etc/dnsmasq.d which end in .conf

            Fix bug when resulted in NXDOMAIN answers instead of NODATA in
            some circumstances.

	    Fix bug which caused dnsmasq to become unresponsive if it
	    failed to send packets due to a network interface disappearing.
	    Thanks to Niels Peen for spotting this.

            Fix problem with --local-service option on big-endian platforms
	    Thanks to Richard Genoud for the patch.


version 2.71
            Subtle change to error handling to help DNSSEC validation
	    when servers fail to provide NODATA answers for
	    non-existent DS records.

	    Tweak code which removes DNSSEC records from answers when
	    not required. Fixes broken answers when additional section
	    has real records in it. Thanks to Marco Davids for the bug
	    report.

	    Fix DNSSEC validation of ANY queries. Thanks to Marco Davids
	    for spotting that too.

	    Fix total DNS failure and 100% CPU use if cachesize set to zero,
	    regression introduced in 2.69. Thanks to James Hunt and
	    the Ubuntu crowd for assistance in fixing this.


version 2.70
            Fix crash, introduced in 2.69, on TCP request when dnsmasq
	    compiled with DNSSEC support, but running without DNSSEC
	    enabled. Thanks to Manish Sing for spotting that one.

	    Fix regression which broke ipset functionality. Thanks to
	    Wang Jian for the bug report.


version 2.69
	    Implement dynamic interface discovery on *BSD. This allows
	    the contructor: syntax to be used in dhcp-range for DHCPv6
	    on the BSD platform. Thanks to Matthias Andree for
	    valuable research on how to implement this.

	    Fix infinite loop associated with some --bogus-nxdomain
	    configs. Thanks fogobogo for the bug report.

	    Fix missing RA RDNS option with configuration like
	    --dhcp-option=option6:23,[::] Thanks to Tsachi Kimeldorfer
	    for spotting the problem.

	    Add [fd00::] and [fe80::] as special addresses in DHCPv6
	    options, analogous to [::]. [fd00::] is replaced with the
	    actual ULA of the interface on the machine running
	    dnsmasq, [fe80::] with the link-local address.
	    Thanks to Tsachi Kimeldorfer for championing this.

	    DNSSEC validation and caching. Dnsmasq needs to be
	    compiled with this enabled, with

	    make dnsmasq COPTS=-DHAVE_DNSSEC

	    this add dependencies on the nettle crypto library and the
	    gmp maths library. It's possible to have these linked
	    statically with

	    make dnsmasq COPTS='-DHAVE_DNSSEC -DHAVE_DNSSEC_STATIC'

	    which bloats the dnsmasq binary, but saves the size of
	    the shared libraries which are much bigger.

	    To enable, DNSSEC, you will need a set of
	    trust-anchors. Now that the TLDs are signed, this can be
	    the keys for the root zone, and for convenience they are
	    included in trust-anchors.conf in the dnsmasq
	    distribution. You should of course check that these are
	    legitimate and up-to-date. So, adding

	    conf-file=/path/to/trust-anchors.conf
	    dnssec

	    to your config is all thats needed to get things
	    working. The upstream nameservers have to be DNSSEC-capable
	    too, of course. Many ISP nameservers aren't, but the
	    Google public nameservers (8.8.8.8 and 8.8.4.4) are.
	    When DNSSEC is configured, dnsmasq validates any queries
	    for domains which are signed. Query results which are
	    bogus are replaced with SERVFAIL replies, and results
	    which are correctly signed have the AD bit set. In
	    addition, and just as importantly, dnsmasq supplies
	    correct DNSSEC information to clients which are doing
	    their own validation, and caches DNSKEY, DS and RRSIG
	    records, which significantly improve the performance of
	    downstream validators. Setting --log-queries will show
	    DNSSEC in action.

	    If a domain is returned from an upstream nameserver without
	    DNSSEC signature, dnsmasq by default trusts this. This
	    means that for unsigned zone (still the majority) there
	    is effectively no cost for having DNSSEC enabled. Of course
	    this allows an attacker to replace a signed record with a
	    false unsigned record. This is addressed by the
	    --dnssec-check-unsigned flag, which instructs dnsmasq
	    to prove that an unsigned record is legitimate, by finding
	    a secure proof that the zone containing the record is not
	    signed. Doing this has costs (typically one or two extra
	    upstream queries). It also has a nasty failure mode if
	    dnsmasq's upstream nameservers are not DNSSEC capable.
	    Without --dnssec-check-unsigned using such an upstream
	    server will simply result in not queries being validated;
	    with --dnssec-check-unsigned enabled and a
	    DNSSEC-ignorant upstream server, _all_ queries will fail.

	    Note that DNSSEC requires that the local time is valid and
	    accurate, if not then DNSSEC validation will fail. NTP
	    should be running. This presents a problem for routers
	    without a battery-backed clock. To set the time needs NTP
	    to do DNS lookups, but lookups will fail until NTP has run.
	    To address this, there's a flag, --dnssec-no-timecheck
	    which disables the time checks (only) in DNSSEC. When dnsmasq
	    is started and the clock is not synced, this flag should
	    be used. As soon as the clock is synced, SIGHUP dnsmasq.
	    The SIGHUP clears the cache of partially-validated data and
	    resets the no-timecheck flag, so that all DNSSEC checks
	    henceforward will be complete.

	    The development of DNSSEC in dnsmasq was started by
	    Giovanni Bajo, to whom huge thanks are owed. It has been
	    supported by Comcast, whose techfund grant has allowed for
	    an invaluable period of full-time work to get it to
	    a workable state.

	    Add --rev-server. Thanks to Dave Taht for suggesting this.

	    Add --servers-file. Allows dynamic update of upstream servers
	    full access to configuration.

	    Add --local-service. Accept DNS queries only from hosts
            whose address is on a local subnet, ie a subnet for which
            an interface exists on the server. This option
            only has effect if there are no --interface --except-interface,
            --listen-address or --auth-server options. It is intended
            to be set as a default on installation, to allow
            unconfigured installations to be useful but also safe from
	    being used for DNS amplification attacks.

	    Fix crashes in cache_get_cname_target() when dangling CNAMEs
	    encountered. Thanks to Andy and the rt-n56u project for
	    find this and helping to chase it down.

	    Fix wrong RCODE in authoritative DNS replies to PTR queries. The
	    correct answer was included, but the RCODE was set to NXDOMAIN.
	    Thanks to Craig McQueen for spotting this.

	    Make statistics available as DNS queries in the .bind TLD as
	    well as logging them.


version 2.68
            Use random addresses for DHCPv6 temporary address
            allocations, instead of algorithmically determined stable
            addresses.

	    Fix bug which meant that the DHCPv6 DUID was not available
	    in DHCP script runs during the lifetime of the dnsmasq
	    process which created the DUID de-novo. Once the DUID was
	    created and stored in the lease file and dnsmasq
	    restarted, this bug disappeared.

	    Fix bug introduced in 2.67 which could result in erroneous
	    NXDOMAIN returns to CNAME queries.

	    Fix build failures on MacOS X and openBSD.

	    Allow subnet specifications in --auth-zone to be interface
	    names as well as address literals. This makes it possible
	    to configure authoritative DNS when local address ranges
	    are dynamic and works much better than the previous
	    work-around which exempted contructed DHCP ranges from the
	    IP address filtering. As a consequence, that work-around
	    is removed. Under certain circumstances, this change wil
	    break existing configuration: if you're relying on the
	    contructed-range exception, you need to change --auth-zone
	    to specify the same interface as is used to construct your
	    DHCP ranges, probably with a trailing "/6" like this:
	    --auth-zone=example.com,eth0/6 to limit the addresses to
	    IPv6 addresses of eth0.

	    Fix problems when advertising deleted IPv6 prefixes. If
	    the prefix is deleted (rather than replaced), it doesn't
	    get advertised with zero preferred time. Thanks to Tsachi
	    for the bug report.

	    Fix segfault with some locally configured CNAMEs. Thanks
	    to Andrew Childs for spotting the problem.

	    Fix memory leak on re-reading /etc/hosts and friends,
	    introduced in 2.67.

	    Check the arrival interface of incoming DNS and TFTP
	    requests via IPv6, even in --bind-interfaces mode. This
	    isn't possible for IPv4 and can generate scary warnings,
	    but as it's always possible for IPv6 (the API always
	    exists) then we should do it always.

	    Tweak the rules on prefix-lengths in --dhcp-range for
	    IPv6. The new rule is that the specified prefix length
	    must be larger than or equal to the prefix length of the
	    corresponding address on the local interface.
