2 Add ra-advrouter mode, for RFC-3775 mobile IPv6 support.
4 Add support for "ipsets" in *BSD, using pf. Thanks to
5 Sven Falempim for the patch.
7 Fix race condition which could lock up dnsmasq when an
8 interface goes down and up rapidly. Thanks to Conrad
9 Kostecki for helping to chase this down.
11 Add DBus methods SetFilterWin2KOption and SetBogusPrivOption
12 Thanks to the Smoothwall project for the patch.
14 Fix failure to build against Nettle-3.0. Thanks to Steven
15 Barth for spotting this and finding the fix.
19 Subtle change to error handling to help DNSSEC validation
20 when servers fail to provide NODATA answers for
21 non-existent DS records.
23 Tweak code which removes DNSSEC records from answers when
24 not required. Fixes broken answers when additional section
25 has real records in it. Thanks to Marco Davids for the bug
28 Fix DNSSEC validation of ANY queries. Thanks to Marco Davids
29 for spotting that too.
31 Fix total DNS failure and 100% CPU use if cachesize set to zero,
32 regression introduced in 2.69. Thanks to James Hunt and
33 the Ubuntu crowd for assistance in fixing this.
37 Fix crash, introduced in 2.69, on TCP request when dnsmasq
38 compiled with DNSSEC support, but running without DNSSEC
39 enabled. Thanks to Manish Sing for spotting that one.
41 Fix regression which broke ipset functionality. Thanks to
42 Wang Jian for the bug report.
46 Implement dynamic interface discovery on *BSD. This allows
47 the contructor: syntax to be used in dhcp-range for DHCPv6
48 on the BSD platform. Thanks to Matthias Andree for
49 valuable research on how to implement this.
51 Fix infinite loop associated with some --bogus-nxdomain
52 configs. Thanks fogobogo for the bug report.
54 Fix missing RA RDNS option with configuration like
55 --dhcp-option=option6:23,[::] Thanks to Tsachi Kimeldorfer
56 for spotting the problem.
58 Add [fd00::] and [fe80::] as special addresses in DHCPv6
59 options, analogous to [::]. [fd00::] is replaced with the
60 actual ULA of the interface on the machine running
61 dnsmasq, [fe80::] with the link-local address.
62 Thanks to Tsachi Kimeldorfer for championing this.
64 DNSSEC validation and caching. Dnsmasq needs to be
65 compiled with this enabled, with
67 make dnsmasq COPTS=-DHAVE_DNSSEC
69 this add dependencies on the nettle crypto library and the
70 gmp maths library. It's possible to have these linked
73 make dnsmasq COPTS='-DHAVE_DNSSEC -DHAVE_DNSSEC_STATIC'
75 which bloats the dnsmasq binary, but saves the size of
76 the shared libraries which are much bigger.
78 To enable, DNSSEC, you will need a set of
79 trust-anchors. Now that the TLDs are signed, this can be
80 the keys for the root zone, and for convenience they are
81 included in trust-anchors.conf in the dnsmasq
82 distribution. You should of course check that these are
83 legitimate and up-to-date. So, adding
85 conf-file=/path/to/trust-anchors.conf
88 to your config is all thats needed to get things
89 working. The upstream nameservers have to be DNSSEC-capable
90 too, of course. Many ISP nameservers aren't, but the
91 Google public nameservers (8.8.8.8 and 8.8.4.4) are.
92 When DNSSEC is configured, dnsmasq validates any queries
93 for domains which are signed. Query results which are
94 bogus are replaced with SERVFAIL replies, and results
95 which are correctly signed have the AD bit set. In
96 addition, and just as importantly, dnsmasq supplies
97 correct DNSSEC information to clients which are doing
98 their own validation, and caches DNSKEY, DS and RRSIG
99 records, which significantly improve the performance of
100 downstream validators. Setting --log-queries will show
103 If a domain is returned from an upstream nameserver without
104 DNSSEC signature, dnsmasq by default trusts this. This
105 means that for unsigned zone (still the majority) there
106 is effectively no cost for having DNSSEC enabled. Of course
107 this allows an attacker to replace a signed record with a
108 false unsigned record. This is addressed by the
109 --dnssec-check-unsigned flag, which instructs dnsmasq
110 to prove that an unsigned record is legitimate, by finding
111 a secure proof that the zone containing the record is not
112 signed. Doing this has costs (typically one or two extra
113 upstream queries). It also has a nasty failure mode if
114 dnsmasq's upstream nameservers are not DNSSEC capable.
115 Without --dnssec-check-unsigned using such an upstream
116 server will simply result in not queries being validated;
117 with --dnssec-check-unsigned enabled and a
118 DNSSEC-ignorant upstream server, _all_ queries will fail.
120 Note that DNSSEC requires that the local time is valid and
121 accurate, if not then DNSSEC validation will fail. NTP
122 should be running. This presents a problem for routers
123 without a battery-backed clock. To set the time needs NTP
124 to do DNS lookups, but lookups will fail until NTP has run.
125 To address this, there's a flag, --dnssec-no-timecheck
126 which disables the time checks (only) in DNSSEC. When dnsmasq
127 is started and the clock is not synced, this flag should
128 be used. As soon as the clock is synced, SIGHUP dnsmasq.
129 The SIGHUP clears the cache of partially-validated data and
130 resets the no-timecheck flag, so that all DNSSEC checks
131 henceforward will be complete.
133 The development of DNSSEC in dnsmasq was started by
134 Giovanni Bajo, to whom huge thanks are owed. It has been
135 supported by Comcast, whose techfund grant has allowed for
136 an invaluable period of full-time work to get it to
139 Add --rev-server. Thanks to Dave Taht for suggesting this.
141 Add --servers-file. Allows dynamic update of upstream servers
142 full access to configuration.
144 Add --local-service. Accept DNS queries only from hosts
145 whose address is on a local subnet, ie a subnet for which
146 an interface exists on the server. This option
147 only has effect if there are no --interface --except-interface,
148 --listen-address or --auth-server options. It is intended
149 to be set as a default on installation, to allow
150 unconfigured installations to be useful but also safe from
151 being used for DNS amplification attacks.
153 Fix crashes in cache_get_cname_target() when dangling CNAMEs
154 encountered. Thanks to Andy and the rt-n56u project for
155 find this and helping to chase it down.
157 Fix wrong RCODE in authoritative DNS replies to PTR queries. The
158 correct answer was included, but the RCODE was set to NXDOMAIN.
159 Thanks to Craig McQueen for spotting this.
161 Make statistics available as DNS queries in the .bind TLD as
162 well as logging them.
166 Use random addresses for DHCPv6 temporary address
167 allocations, instead of algorithmically determined stable
170 Fix bug which meant that the DHCPv6 DUID was not available
171 in DHCP script runs during the lifetime of the dnsmasq
172 process which created the DUID de-novo. Once the DUID was
173 created and stored in the lease file and dnsmasq
174 restarted, this bug disappeared.
176 Fix bug introduced in 2.67 which could result in erroneous
177 NXDOMAIN returns to CNAME queries.
179 Fix build failures on MacOS X and openBSD.
181 Allow subnet specifications in --auth-zone to be interface
182 names as well as address literals. This makes it possible
183 to configure authoritative DNS when local address ranges
184 are dynamic and works much better than the previous
185 work-around which exempted contructed DHCP ranges from the
186 IP address filtering. As a consequence, that work-around
187 is removed. Under certain circumstances, this change wil
188 break existing configuration: if you're relying on the
189 contructed-range exception, you need to change --auth-zone
190 to specify the same interface as is used to construct your
191 DHCP ranges, probably with a trailing "/6" like this:
192 --auth-zone=example.com,eth0/6 to limit the addresses to
193 IPv6 addresses of eth0.
195 Fix problems when advertising deleted IPv6 prefixes. If
196 the prefix is deleted (rather than replaced), it doesn't
197 get advertised with zero preferred time. Thanks to Tsachi
200 Fix segfault with some locally configured CNAMEs. Thanks
201 to Andrew Childs for spotting the problem.
203 Fix memory leak on re-reading /etc/hosts and friends,
206 Check the arrival interface of incoming DNS and TFTP
207 requests via IPv6, even in --bind-interfaces mode. This
208 isn't possible for IPv4 and can generate scary warnings,
209 but as it's always possible for IPv6 (the API always
210 exists) then we should do it always.
212 Tweak the rules on prefix-lengths in --dhcp-range for
213 IPv6. The new rule is that the specified prefix length
214 must be larger than or equal to the prefix length of the
215 corresponding address on the local interface.
219 Fix crash if upstream server returns SERVFAIL when
220 --conntrack in use. Thanks to Giacomo Tazzari for finding
221 this and supplying the patch.
223 Repair regression in 2.64. That release stopped sending
224 lease-time information in the reply to DHCPINFORM
225 requests, on the correct grounds that it was a standards
226 violation. However, this broke the dnsmasq-specific
227 dhcp_lease_time utility. Now, DHCPINFORM returns
228 lease-time only if it's specifically requested
229 (maintaining standards) and the dhcp_lease_time utility
230 has been taught to ask for it (restoring functionality).
232 Fix --dhcp-match, --dhcp-vendorclass and --dhcp-userclass
233 to work with BOOTP and well as DHCP. Thanks to Peter
234 Korsgaard for spotting the problem.
236 Add --synth-domain. Thanks to Vishvananda Ishaya for
239 Fix failure to compile ipset.c if old kernel headers are
240 in use. Thanks to Eugene Rudoy for pointing this out.
242 Handle IPv4 interface-address labels in Linux. These are
243 often used to emulate the old IP-alias addresses. Before,
244 using --interface=eth0 would service all the addresses of
245 eth0, including ones configured as aliases, which appear
246 in ifconfig as eth0:0. Now, only addresses with the label
247 eth0 are active. This is not backwards compatible: if you
248 want to continue to bind the aliases too, you need to add
249 eg. --interface=eth0:0 to the config.
251 Fix "failed to set SO_BINDTODEVICE on DHCP socket: Socket
252 operation on non-socket" error on startup with
253 configurations which have exactly one --interface option
254 and do RA but _not_ DHCPv6. Thanks to Trever Adams for the
257 Generalise --interface-name to cope with IPv6 addresses
258 and multiple addresses per interface per address family.
260 Fix option parsing for --dhcp-host, which was generating a
261 spurious error when all seven possible items were
262 included. Thanks to Zhiqiang Wang for the bug report.
264 Remove restriction on prefix-length in --auth-zone. Thanks
265 to Toke Hoiland-Jorgensen for suggesting this.
267 Log when the maximum number of concurrent DNS queries is
268 reached. Thanks to Marcelo Salhab Brogliato for the patch.
270 If wildcards are used in --interface, don't assume that
271 there will only ever be one available interface for DHCP
272 just because there is one at start-up. More may appear, so
273 we can't use SO_BINDTODEVICE. Thanks to Natrio for the bug
276 Increase timeout/number of retries in TFTP to accomodate
277 AudioCodes Voice Gateways doing streaming writes to flash.
278 Thanks to Damian Kaczkowski for spotting the problem.
280 Fix crash with empty DHCP string options when adding zero
281 terminator. Thanks to Patrick McLean for the bug report.
283 Allow hostnames to start with a number, as allowed in
284 RFC-1123. Thanks to Kyle Mestery for the patch.
286 Fixes to DHCP FQDN option handling: don't terminate FQDN
287 if domain not known and allow a FQDN option with blank
288 name to request that a FQDN option is returned in the
289 reply. Thanks to Roy Marples for the patch.
291 Make --clear-on-reload apply to setting upstream servers
294 When the address which triggered the construction of an
295 advertised IPv6 prefix disappears, continue to advertise
296 the prefix for up to 2 hours, with the preferred lifetime
297 set to zero. This satisfies RFC 6204 4.3 L-13 and makes
298 things work better if a prefix disappears without being
299 deprecated first. Thanks to Uwe Schindler for persuasively
302 Fix MAC address enumeration on *BSD. Thanks to Brad Smith
305 Support RFC-4242 information-refresh-time options in the
306 reply to DHCPv6 information-request. The lease time of the
307 smallest valid dhcp-range is sent. Thanks to Uwe Schindler
310 Make --listen-address higher priority than --except-interface
311 in all circumstances. Thanks to Thomas Hood for the bugreport.
313 Provide independent control over which interfaces get TFTP
314 service. If enable-tftp is given a list of interfaces, then TFTP
315 is provided on those. Without the list, the previous behaviour
316 (provide TFTP to the same interfaces we provide DHCP to)
317 is retained. Thanks to Lonnie Abelbeck for the suggestion.
319 Add --dhcp-relay config option. Many thanks to vtsl.net
320 for sponsoring this development.
322 Fix crash with empty tag: in --dhcp-range. Thanks to
323 Kaspar Schleiser for the bug report.
325 Add "baseline" and "bloatcheck" makefile targets, for
326 revealing size changes during development. Thanks to
327 Vladislav Grishenko for the patch.
329 Cope with DHCPv6 clients which send REQUESTs without
330 address options - treat them as SOLICIT with rapid commit.
332 Support identification of clients by MAC address in
333 DHCPv6. When using a relay, the relay must support RFC
334 6939 for this to work. It always works for directly
335 connected clients. Thanks to Vladislav Grishenko
336 for prompting this feature.
338 Remove the rule for constructed DHCP ranges that the local
339 address must be either the first or last address in the
340 range. This was originally to avoid SLAAC addresses, but
341 we now explicitly autoconfig and privacy addresses instead.
343 Update Polish translation. Thanks to Jan Psota.
345 Fix problem in DHCPv6 vendorclass/userclass matching
346 code. Thanks to Tanguy Bouzeloc for the patch.
348 Update Spanish transalation. Thanks to Vicente Soriano.
350 Add --ra-param option. Thanks to Vladislav Grishenko for
353 Add --add-subnet configuration, to tell upstream DNS
354 servers where the original client is. Thanks to DNSthingy
355 for sponsoring this feature.
357 Add --quiet-dhcp, --quiet-dhcp6 and --quiet-ra. Thanks to
358 Kevin Darbyshire-Bryant for the initial patch.
360 Allow A/AAAA records created by --interface-name to be the
361 target of --cname. Thanks to Hadmut Danisch for the
364 Avoid treating a --dhcp-host which has an IPv6 address
365 as eligable for use with DHCPv4 on the grounds that it has
366 no address, and vice-versa. Thanks to Yury Konovalov for
367 spotting the problem.
369 Do a better job caching dangling CNAMEs. Thanks to Yves
370 Dorfsman for spotting the problem.
374 Add the ability to act as an authoritative DNS
375 server. Dnsmasq can now answer queries from the wider 'net
376 with local data, as long as the correct NS records are set
377 up. Only local data is provided, to avoid creating an open
378 DNS relay. Zone transfer is supported, to allow secondary
379 servers to be configured.
381 Add "constructed DHCP ranges" for DHCPv6. This is intended
382 for IPv6 routers which get prefixes dynamically via prefix
383 delegation. With suitable configuration, stateful DHCPv6
384 and RA can happen automatically as prefixes are delegated
385 and then deprecated, without having to re-write the
386 dnsmasq configuration file or restart the daemon. Thanks to
387 Steven Barth for extensive testing and development work on
390 Fix crash on startup on Solaris 11. Regression probably
391 introduced in 2.61. Thanks to Geoff Johnstone for the
394 Add code to make behaviour for TCP DNS requests that same
395 as for UDP requests, when a request arrives for an allowed
396 address, but via a banned interface. This change is only
397 active on Linux, since the relevant API is missing (AFAIK)
398 on other platforms. Many thanks to Tomas Hozza for
399 spotting the problem, and doing invaluable discovery of
400 the obscure and undocumented API required for the solution.
402 Don't send the default DHCP option advertising dnsmasq as
403 the local DNS server if dnsmasq is configured to not act
404 as DNS server, or it's configured to a non-standard port.
406 Add DNSMASQ_CIRCUIT_ID, DNSMASQ_SUBCRIBER_ID,
407 DNSMASQ_REMOTE_ID variables to the environment of the
408 lease-change script (and the corresponding Lua). These hold
409 information inserted into the DHCP request by a DHCP relay
410 agent. Thanks to Lakefield Communications for providing a
411 bounty for this addition.
413 Fixed crash, introduced in 2.64, whilst handling DHCPv6
414 information-requests with some common configurations.
415 Thanks to Robert M. Albrecht for the bug report and
418 Add --ipset option. Thanks to Jason A. Donenfeld for the
421 Don't erroneously reject some option names in --dhcp-match
422 options. Thanks to Benedikt Hochstrasser for the bug report.
424 Allow a trailing '*' wildcard in all interface-name
425 configurations. Thanks to Christian Parpart for the patch.
427 Handle the situation where libc headers define
428 SO_REUSEPORT, but the kernel in use doesn't, to cope with
429 the introduction of this option to Linux. Thanks to Rich
430 Felker for the bug report.
432 Update Polish translation. Thanks to Jan Psota.
434 Fix crash if the configured DHCP lease limit is
435 reached. Regression occurred in 2.61. Thanks to Tsachi for
438 Update the French translation. Thanks to Gildas le Nadan.
442 Fix regression which broke forwarding of queries sent via
443 TCP which are not for A and AAAA and which were directed to
444 non-default servers. Thanks to Niax for the bug report.
446 Fix failure to build with DHCP support excluded. Thanks to
447 Gustavo Zacarias for the patch.
449 Fix nasty regression in 2.64 which completely broke cacheing.
453 Handle DHCP FQDN options with all flag bits zero and
454 --dhcp-client-update set. Thanks to Bernd Krumbroeck for
455 spotting the problem.
457 Finesse the check for /etc/hosts names which conflict with
458 DHCP names. Previously a name/address pair in /etc/hosts
459 which didn't match the name/address of a DHCP lease would
460 generate a warning. Now that only happesn if there is not
461 also a match. This allows multiple addresses for a name in
462 /etc/hosts with one of them assigned via DHCP.
464 Fix broken vendor-option processing for BOOTP. Thanks to
465 Hans-Joachim Baader for the bug report.
467 Don't report spurious netlink errors, regression in
468 2.63. Thanks to Vladislav Grishenko for the patch.
470 Flag DHCP or DHCPv6 in starup logging. Thanks to
471 Vladislav Grishenko for the patch.
473 Add SetServersEx method in DBus interface. Thanks to Dan
474 Williams for the patch.
476 Add SetDomainServers method in DBus interface. Thanks to
477 Roy Marples for the patch.
479 Fix build with later Lua libraries. Thansk to Cristian
480 Rodriguez for the patch.
482 Add --max-cache-ttl option. Thanks to Dennis Kaarsemaker
485 Fix breakage of --host-record parsing, resulting in
486 infinte loop at startup. Regression in 2.63. Thanks to
487 Haim Gelfenbeyn for spotting this.
489 Set SO_REUSEADDRESS and SO_V6ONLY options on the DHCPv6
490 socket, this allows multiple instances of dnsmasq on a
491 single machine, in the same way as for DHCPv4. Thanks to
492 Gene Czarcinski and Vladislav Grishenko for work on this.
494 Fix DHCPv6 to do access control correctly when it's
495 configured with --listen-address. Thanks to
496 Gene Czarcinski for sorting this out.
498 Add a "wildcard" dhcp-range which works for any IPv6
499 subnet, --dhcp-range=::,static Useful for Stateless
500 DHCPv6. Thanks to Vladislav Grishenko for the patch.
502 Don't include lease-time in DHCPACK replies to DHCPINFORM
503 queries, since RFC-2131 says we shouldn't. Thanks to
504 Wouter Ibens for pointing this out.
506 Makefile tweak to do dependency checking on header files.
507 Thanks to Johan Peeters for the patch.
509 Check interface for outgoing unsolicited router
510 advertisements, rather than relying on interface address
511 configuration. Thanks to Gene Czarinski for the patch.
513 Handle better attempts to transmit on interfaces which are
514 still doing DAD, and specifically do not just transmit
515 without setting source address and interface, since this
516 can cause very puzzling effects when a router
517 advertisement goes astray. Thanks again to Gene Czarinski.
519 Get RA timers right when there is more than one
520 dhcp-range on a subnet.
524 Do duplicate dhcp-host address check in --test mode.
526 Check that tftp-root directories are accessible before
527 start-up. Thanks to Daniel Veillard for the initial patch.
529 Allow more than one --tfp-root flag. The per-interface
530 stuff is pointless without that.
532 Add --bind-dynamic. A hybrid mode between the default and
533 --bind-interfaces which copes with dynamically created
536 A couple of fixes to the build system for Android. Thanks
537 to Metin Kaya for the patches.
539 Remove the interface:<interface> argument in --dhcp-range, and
540 the interface argument to --enable-tftp. These were a
541 still-born attempt to allow automatic isolated
542 configuration by libvirt, but have never (to my knowledge)
543 been used, had very strange semantics, and have been
544 superceded by other mechanisms.
546 Fixed bug logging filenames when duplicate dhcp-host
547 addresses are found. Thanks to John Hanks for the patch.
549 Fix regression in 2.61 which broke caching of CNAME
550 chains. Thanks to Atul Gupta for the bug report.
552 Allow the target of a --cname flag to be another --cname.
554 Teach DHCPv6 about the RFC 4242 information-refresh-time
555 option, and add parsing if the minutes, hours and days
556 format for options. Thanks to Francois-Xavier Le Bail for
559 Allow "w" (for week) as multiplier in lease times, as well
560 as seconds, minutes, hours and days. Álvaro Gámez Machado
561 spotted the ommission.
563 Update French translation. Thanks to Gildas Le Nadan.
565 Allow a DBus service name to be given with --enable-dbus
566 which overrides the default,
567 uk.org.thekelleys.dnsmasq. Thanks to Mathieu
568 Trudel-Lapierre for the patch.
570 Set the "prefix on-link" bit in Router
571 Advertisements. Thanks to Gui Iribarren for the patch.
575 Update German translation. Thanks to Conrad Kostecki.
577 Cope with router-solict packets wich don't have a valid
578 source address. Thanks to Vladislav Grishenko for the patch.
580 Fixed bug which caused missing periodic router
581 advertisements with some configurations. Thanks to
582 Vladislav Grishenko for the patch.
584 Fixed bug which broke DHCPv6/RA with prefix lengths
585 which are not divisible by 8. Thanks to Andre Coetzee
588 Fix non-response to router-solicitations when
589 router-advertisement configured, but DHCPv6 not
590 configured. Thanks to Marien Zwart for the patch.
592 Add --dns-rr, to allow arbitrary DNS resource records.
594 Fixed bug which broke RA scheduling when an interface had
595 two addresses in the same network. Thanks to Jim Bos for
596 his help nailing this.
599 Re-write interface discovery code on *BSD to use
600 getifaddrs. This is more portable, more straightforward,
601 and allows us to find the prefix length for IPv6
604 Add ra-names, ra-stateless and slaac keywords for DHCPv6.
605 Dnsmasq can now synthesise AAAA records for dual-stack
606 hosts which get IPv6 addresses via SLAAC. It is also now
607 possible to use SLAAC and stateless DHCPv6, and to
608 tell clients to use SLAAC addresses as well as DHCP ones.
609 Thanks to Dave Taht for help with this.
611 Add --dhcp-duid to allow DUID-EN uids to be used.
613 Explicity send DHCPv6 replies to the correct port, instead
614 of relying on clients to send requests with the correct
615 source address, since at least one client in the wild gets
616 this wrong. Thanks to Conrad Kostecki for help tracking
619 Send a preference value of 255 in DHCPv6 replies when
620 --dhcp-authoritative is in effect. This tells clients not
621 to wait around for other DHCP servers.
623 Better logging of DHCPv6 options.
625 Add --host-record. Thanks to Rob Zwissler for the
628 Invoke the DHCP script with action "tftp" when a TFTP file
629 transfer completes. The size of the file, address to which
630 it was sent and complete pathname are supplied. Note that
631 version 2.60 introduced some script incompatibilties
632 associated with DHCPv6, and this is a further change. To
633 be safe, scripts should ignore unknown actions, and if
634 not IPv6-aware, should exit if the environment
635 variable DNSMASQ_IAID is set. The use-case for this is
636 to track netboot/install. Suggestion from Shantanu
639 Update contrib/port-forward/dnsmasq-portforward to reflect
642 Set the environment variable DNSMASQ_LOG_DHCP when running
643 the script id --log-dhcp is in effect, so that script can
644 taylor their logging verbosity. Suggestion from Malte
647 Arrange that addresses specified with --listen-address
648 work even if there is no interface carrying the
649 address. This is chiefly useful for IPv4 loopback
650 addresses, where any address in 127.0.0.0/8 is a valid
651 loopback address, but normally only 127.0.0.1 appears on
652 the lo interface. Thanks to Mathieu Trudel-Lapierre for
653 the idea and initial patch.
655 Fix crash, introduced in 2.60, when a DHCPINFORM is
656 received from a network which has no valid dhcp-range.
657 Thanks to Stephane Glondu for the bug report.
659 Add a new DHCP lease time keyword, "deprecated" for
660 --dhcp-range. This is only valid for IPv6, and sets the
661 preffered lease time for both DHCP and RA to zero. The
662 effect is that clients can continue to use the address
663 for existing connections, but new connections will use
664 other addresses, if they exist. This makes hitless
665 renumbering at least possible.
667 Fix bug in address6_available() which caused DHCPv6 lease
668 aquisition to fail if more than one dhcp-range in use.
670 Provide RDNSS and DNSSL data in router advertisements,
671 using the settings provided for DHCP options
672 option6:domain-search and option6:dns-server.
674 Tweak logo/favicon.ico to add some transparency. Thanks to
675 SamLT for work on this.
677 Don't cache data from non-recursive nameservers, since it
678 may erroneously look like a valid CNAME to a non-exitant
679 name. Thanks to Ben Winslow for finding this.
681 Call SO_BINDTODEVICE on the DHCP socket(s) when doing DHCP
682 on exactly one interface and --bind-interfaces is set. This
683 makes the OpenStack use-case of one dnsmasq per virtual
684 interface work. This is only available on Linux; it's not
685 supported on other platforms. Thanks to Vishvananda Ishaya
686 and the OpenStack team for the suggestion.
688 Updated French translation. Thanks to Gildas Le Nadan.
690 Give correct from-cache answers to explict CNAME queries.
691 Thanks to Rob Zwissler for spotting this.
693 Add --tftp-lowercase option. Thanks to Oliver Rath for the
696 Ensure that the DBus DhcpLeaseUpdated events are generated
697 when a lease goes through INIT_REBOOT state, even if the
698 dhcp-script is not in use. Thanks to Antoaneta-Ecaterina
701 Fix failure of TFTP over IPv4 on OpenBSD platform. Thanks
702 to Brad Smith for spotting this.
706 Fix compilation problem in Mac OS X Lion. Thanks to Olaf
707 Flebbe for the patch.
709 Fix DHCP when using --listen-address with an IP address
710 which is not the primary address of an interface.
712 Add --dhcp-client-update option.
714 Add Lua integration. Dnsmasq can now execute a DHCP
715 lease-change script written in Lua. This needs to be
716 enabled at compile time by setting HAVE_LUASCRIPT in
717 src/config.h or running "make COPTS=-DHAVE_LUASCRIPT"
718 Thanks to Jan-Piet Mens for the idea and proof-of-concept
721 Tidied src/config.h to distinguish between
722 platform-dependent compile-time options which are selected
723 automatically, and builder-selectable compile time
724 options. Document the latter better, and describe how to
725 set them from the make command line.
727 Tidied up IPPROTO_IP/SOL_IP (and IPv6 equivalent)
728 confusion. IPPROTO_IP works everywhere now.
730 Set TOS on DHCP sockets, this improves things on busy
731 wireless networks. Thanks to Dave Taht for the patch.
733 Determine VERSION automatically based on git magic:
734 release tags or hash values.
736 Improve start-up speed when reading large hosts files
737 containing many distinct addresses.
739 Fix problem if dnsmasq is started without the stdin,
740 stdout and stderr file descriptors open. This can manifest
741 itself as 100% CPU use. Thanks to Chris Moore for finding
744 Fix shell-scripting bug in bld/pkg-wrapper. Thanks to
745 Mark Mitchell for the patch.
747 Allow the TFP server or boot server in --pxe-service, to
748 be a domain name instead of an IP address. This allows for
749 round-robin to multiple servers, in the same way as
750 --dhcp-boot. A good suggestion from Cristiano Cumer.
752 Support BUILDDIR variable in the Makefile. Allows builds
753 for multiple archs from the same source tree with eg.
754 make BUILDDIR=linux (relative to dnsmasq tree)
755 make BUILDDIR=/tmp/openbsd (absolute path)
756 If BUILDDIR is not set, compilation happens in the src
757 directory, as before. Suggestion from Mark Mitchell.
759 Support DHCPv6. Support is there for the sort of things
760 the existing v4 server does, including tags, options,
761 static addresses and relay support. Missing is prefix
762 delegation, which is probably not required in the dnsmasq
763 niche, and an easy way to accept prefix delegations from
764 an upstream DHCPv6 server, which is. Future plans include
765 support for DHCPv6 router option and MAC address option
766 (to make selecting clients by MAC address work like IPv4).
767 These will be added as the standards mature.
768 This code has been tested, but this is the first release,
769 so don't bet the farm on it just yet. Many thanks to all
770 testers who have got it this far.
772 Support IPv6 router advertisements. This is a
773 simple-minded implementation, aimed at providing the
774 vestigial RA needed to go alongside IPv6. Is picks up
775 configuration from the DHCPv6 conf, and should just need
776 enabling with --enable-ra.
778 Fix long-standing wrinkle with --localise-queries that
779 could result in wrong answers when DNS packets arrive
780 via an interface other than the expected one. Thanks to
781 Lorenzo Milesi and John Hanks for spotting this one.
783 Update French translation. Thanks to Gildas Le Nadan.
785 Update Polish translation. Thanks to Jan Psota.
789 Fix regression in 2.58 which caused failure to start up
790 with some combinations of dnsmasq config and IPv6 kernel
791 network config. Thanks to Brielle Bruns for the bug
794 Improve dnsmasq's behaviour when network interfaces are
795 still doing duplicate address detection (DAD). Previously,
796 dnsmasq would wait up to 20 seconds at start-up for the
797 DAD state to terminate. This is broken for bridge
798 interfaces on recent Linux kernels, which don't start DAD
799 until the bridge comes up, and so can take arbitrary
800 time. The new behaviour lets dnsmasq poll for an arbitrary
801 time whilst providing service on other interfaces. Thanks
802 to Stephen Hemminger for pointing out the problem.
806 Provide a definition of the SA_SIZE macro where it's
807 missing. Fixes build failure on openBSD.
809 Don't include a zero terminator at the end of messages
810 sent to /dev/log when /dev/log is a datagram socket.
811 Thanks to Didier Rabound for spotting the problem.
813 Add --dhcp-sequential-ip flag, to force allocation of IP
814 addresses in ascending order. Note that the default
815 pseudo-random mode is in general better but some
816 server-deployment applications need this.
818 Fix problem where a server-id of 0.0.0.0 is sent to a
819 client when a dhcp-relay is in use if a client renews a
820 lease after dnsmasq restart and before any clients on the
821 subnet get a new lease. Thanks to Mike Ruiz for assistance
822 in chasing this one down.
824 Don't return NXDOMAIN to an AAAA query if we have CNAME
825 which points to an A record only: NODATA is the correct
826 reply in this case. Thanks to Tom Fernandes for spotting
829 Relax the need to supply a netmask in --dhcp-range for
830 networks which use a DHCP relay. Whilst this is still
831 desireable, in the absence of a netmask dnsmasq will use
832 a default based on the class (A, B, or C) of the address.
833 This should at least remove a cause of mysterious failure
834 for people using RFC1918 addresses and relays.
836 Add support for Linux conntrack connection marking. If
837 enabled with --conntrack, the connection mark for incoming
838 DNS queries will be copied to the outgoing connections
839 used to answer those queries. This allows clever firewall
840 and accounting stuff. Only available if dnsmasq is
841 compiled with HAVE_CONNTRACK and adds a dependency on
842 libnetfilter-conntrack. Thanks to Ed Wildgoose for the
843 initial idea, testing and sponsorship of this function.
845 Provide a sane error message when someone attempts to
846 match a tag in --dhcp-host.
848 Tweak the behaviour of --domain-needed, to avoid problems
849 with recursive nameservers downstream of dnsmasq. The new
850 behaviour only stops A and AAAA queries, and returns
851 NODATA rather than NXDOMAIN replies.
853 Efficiency fix for very large DHCP configurations, thanks
854 to James Gartrell and Mike Ruiz for help with this.
856 Allow the TFTP-server address in --dhcp-boot to be a
857 domain-name which is looked up in /etc/hosts. This can
858 give multiple IP addresses which are used round-robin,
859 thus doing TFTP server load-balancing. Thanks to Sushil
860 Agrawal for the patch.
862 When two tagged dhcp-options for a particular option
863 number are both valid, use the one which is valid without
864 a tag from the dhcp-range. Allows overriding of the value
865 of a DHCP option for a particular host as well as
866 per-network values. So
867 --dhcp-range=set:interface1,......
868 --dhcp-host=set:myhost,.....
869 --dhcp-option=tag:interface1,option:nis-domain,"domain1"
870 --dhcp-option=tag:myhost,option:nis-domain,"domain2"
871 will set the NIS-domain to domain1 for hosts in the range, but
872 override that to domain2 for a particular host.
874 Fix bug which resulted in truncated files and timeouts for
875 some TFTP transfers. The bug only occurs with netascii
876 transfers and needs an unfortunate relationship between
877 file size, blocksize and the number of newlines in the
878 last block before it manifests itself. Many thanks to
879 Alkis Georgopoulos for spotting the problem and providing
880 a comprehensive test-case.
882 Fix regression in TFTP server on *BSD platforms introduced
883 in version 2.56, due to confusion with sockaddr
884 length. Many thanks to Loic Pefferkorn for finding this.
886 Support scope-ids in IPv6 addresses of nameservers from
887 /etc/resolv.conf and in --server options. Eg
888 nameserver fe80::202:a412:4512:7bbf%eth0 or
889 server=fe80::202:a412:4512:7bbf%eth0. Thanks to
890 Michael Stapelberg for the suggestion.
892 Update Polish translation, thanks to Jan Psota.
894 Update French translation. Thanks to Gildas Le Nadan.
898 Add patches to allow build under Android.
900 Provide our own header for the DNS protocol, rather than
901 relying on arpa/nameser.h. This has proved more or less
902 defective over the years and the final straw is that it's
903 effectively empty on Android.
905 Fix regression in 2.56 which caused hex constants in
906 configuration to be rejected if they contain the '*'
909 Correct wrong casts of arguments to ctype.h functions,
910 isdigit(), isxdigit() etc. Thanks to Matthias Andree for
913 Allow build with IDN support independently from i18n.
914 IDN support continues to be included automatically
915 when i18n is included.
916 'make COPTS=-DHAVE_IDN' is the magic incantation.
918 Modify check on extraneous command line junk (added in
919 2.56) so that it doesn't complain about extra _empty_
920 arguments. Otherwise this breaks libvirt.
924 Add a patch to allow dnsmasq to get interface names right in a
925 Solaris zone. Thanks to Dj Padzensky for this.
927 Improve data-type parsing heuristics so that
928 --dhcp-option=option:domain-search,.
929 treats the value as a string and not an IP address.
930 Thanks to Clemens Fischer for spotting that.
932 Add IPv6 support to the TFTP server. Many thanks to Jan
933 'RedBully' Seiffert for the patches.
935 Log DNS queries at level LOG_INFO, rather then
936 LOG_DEBUG. This makes things consistent with DHCP
937 logging. Thanks to Adam Pribyl for spotting the problem.
939 Ensure that dnsmasq terminates cleanly when using
940 --syslog-async even if it cannot make a connection to the
943 Add --add-mac option. This is to support currently
944 experimental DNS filtering facilities. Thanks to Benjamin
945 Petrin for the orignal patch.
947 Fix bug which meant that tags were ignored in dhcp-range
948 configuration specifying PXE-proxy service. Thanks to
949 Cristiano Cumer for spotting this.
951 Raise an error if there is extra junk, not part of an
952 option, on the command line.
954 Flag a couple of log messages in cache.c as coming from
955 the DHCP subsystem. Thanks to Olaf Westrik for the patch.
957 Omit timestamps from logs when a) logging to stderr and
958 b) --keep-in-forground is set. The logging facility on the
959 other end of stderr can be assumned to supply them. Thanks
960 to John Hallam for the patch.
962 Don't complain about strings longer than 255 characters in
963 --txt-record, just split the long strings into 255
964 character chunks instead.
966 Fix crash on double-free. This bug can only happen when
967 dhcp-script is in use and then only in rare circumstances
968 triggered by high DHCP transaction rate and a slow
969 script. Thanks to Ferenc Wagner for finding the problem.
971 Only log that a file has been sent by TFTP after the
972 transfer has completed succesfully.
974 A good suggestion from Ferenc Wagner: extend
975 the --domain option to allow this sort of thing:
976 --domain=thekelleys.org.uk,192.168.0.0/24,local
977 which automatically creates
978 --local=/thekelleys.org.uk/
979 --local=/0.168.192.in-addr.arpa/
981 Tighten up syntax checking of hex contants in the config
982 file. Thanks to Fred Damen for spotting this.
984 Add dnsmasq logo/icon, contributed by Justin Swift. Many
987 Never cache DNS replies which have the 'cd' bit set, or
988 which result from queries forwarded with the 'cd' bit
989 set. The 'cd' bit instructs a DNSSEC validating server
990 upstream to ignore signature failures and return replies
991 anyway. Without this change it's possible to pollute the
992 dnsmasq cache with bad data by making a query with the
993 'cd' bit set and subsequent queries would return this data
994 without its being marked as suspect. Thanks to Anders
995 Kaseorg for pointing out this problem.
997 Add --proxy-dnssec flag, for compliance with RFC
998 4035. Dnsmasq will now clear the 'ad' bit in answers returned
999 from upstream validating nameservers unless this option is
1002 Allow a filename of "-" for --conf-file to read
1003 stdin. Suggestion from Timothy Redaelli.
1005 Rotate the order of SRV records in replies, to provide
1006 round-robin load balancing when all the priorities are
1007 equal. Thanks to Peter McKinney for the suggestion.
1010 contrib/MacOSX-launchd/uk.org.thekelleys.dnsmasq.plist
1011 so that it doesn't log all queries to a file by
1012 default. Thanks again to Peter McKinney.
1014 By default, setting an IPv4 address for a domain but not
1015 an IPv6 address causes dnsmasq to return
1016 an NODATA reply for IPv6 (or vice-versa). So
1017 --address=/google.com/1.2.3.4 stops IPv6 queries for
1018 *google.com from being forwarded. Make it possible to
1019 override this behaviour by defining the sematics if the
1020 same domain appears in both --server and --address.
1021 In that case, the --address has priority for the address
1022 family in which is appears, but the --server has priority
1023 of the address family which doesn't appear in --adddress
1025 --address=/google.com/1.2.3.4
1026 --server=/google.com/#
1027 will return 1.2.3.4 for IPv4 queries for *.google.com but
1028 forward IPv6 queries to the normal upstream nameserver.
1029 Similarly when setting an IPv6 address
1030 only this will allow forwarding of IPv4 queries. Thanks to
1031 William for pointing out the need for this.
1033 Allow more than one --dhcp-optsfile and --dhcp-hostsfile
1034 and make them understand directories as arguments in the
1035 same way as --addn-hosts. Suggestion from John Hanks.
1037 Ignore rebinding requests for leases we don't know
1038 about. Rebind is broadcast, so we might get to overhear a
1039 request meant for another DHCP server. NAKing this is
1040 wrong. Thanks to Brad D'Hondt for assistance with this.
1042 Fix cosmetic bug which produced strange output when
1043 dumping cache statistics with some configurations. Thanks
1044 to Fedor Kozhevnikov for spotting this.
1048 Fix crash when /etc/ethers is in use. Thanks to
1049 Gianluigi Tiesi for finding this.
1051 Fix crash in netlink_multicast(). Thanks to Arno Wald for
1054 Allow the empty domain "." in dhcp domain-search (119)
1059 There is no version 2.54 to avoid confusion with 2.53,
1060 which incorrectly identifies itself as 2.54.
1064 Fix failure to compile on Debian/kFreeBSD. Thanks to
1065 Axel Beckert and Petr Salinger.
1067 Fix code to avoid scary strict-aliasing warnings
1068 generated by gcc 4.4.
1070 Added FAQ entry warning about DHCP failures with Vista
1071 when firewalls block 255.255.255.255.
1073 Fixed bug which caused bad things to happen if a
1074 resolv.conf file which exists is subsequently removed.
1075 Thanks to Nikolai Saoukh for the patch.
1077 Rationalised the DHCP tag system. Every configuration item
1078 which can set a tag does so by adding "set:<tag>" and
1079 every configuration item which is conditional on a tag is
1080 made so by "tag:<tag>". The NOT operator changes to '!',
1081 which is a bit more intuitive too. Dhcp-host directives
1082 can set more than one tag now. The old '#' NOT,
1083 "net:" prefix and no-prefixes are still honoured, so
1084 no existing config file needs to be changed, but
1085 the documentation and new-style config files should be
1086 much less confusing.
1088 Added --tag-if to allow boolean operations on tags.
1089 This allows complicated logic to be clearer and more
1090 general. A great suggestion from Richard Voigt.
1092 Add broadcast/unicast information to DHCP logging.
1094 Allow --dhcp-broadcast to be unconditional.
1096 Fixed incorrect behaviour with NOT <tag> conditionals in
1097 dhcp-options. Thanks to Max Turkewitz for assistance
1100 If we send vendor-class encapsulated options based on the
1101 vendor-class supplied by the client, and no explicit
1102 vendor-class option is given, echo back the vendor-class
1105 Fix bug which stopped dnsmasq from matching both a
1106 circuitid and a remoteid. Thanks to Ignacio Bravo for
1109 Add --dhcp-proxy, which makes it possible to configure
1110 dnsmasq to use a DHCP relay agent as a full proxy, with
1111 all DHCP messages passing through the proxy. This is
1112 useful if the relay adds extra information to the packets
1113 it forwards, but cannot be configured with the RFC 5107
1114 server-override option.
1116 Added interface:<iface name> part to dhcp-range. The
1117 semantics of this are very odd at first sight, but it
1118 allows a single line of the form
1119 dhcp-range=interface:virt0,192.168.0.4,192.168.0.200
1120 to be added to dnsmasq configuration which then supplies
1121 DHCP and DNS services to that interface, without affecting
1122 what services are supplied to other interfaces and
1123 irrespective of the existance or lack of
1124 interface=<interface>
1125 lines elsewhere in the dnsmasq configuration. The idea is
1126 that such a line can be added automatically by libvirt
1127 or equivalent systems, without disturbing any manual
1130 Similarly to the above, allow --enable-tftp=<interface>
1132 Allow a TFTP root to be set separately for requests via
1133 different interfaces, --tftp-root=<path>,<interface>
1135 Correctly handle and log clashes between CNAMES and
1136 DNS names being given to DHCP leases. This fixes a bug
1137 which caused nonsense IP addresses to be logged. Thanks to
1138 Sergei Zhirikov for finding and analysing the problem.
1140 Tweak flush_log so as to avoid leaving the log
1141 file in non-blocking mode. O_NONBLOCK is a property of the
1142 file, not the process/descriptor.
1144 Fix contrib/Solaris10/create_package
1145 (/usr/man -> /usr/share/man) Thanks to Vita Batrla.
1147 Fix a problem where, if a client got a lease, then went
1148 to another subnet and got another lease, then moved back,
1149 it couldn't resume the old lease, but would instead get
1150 a new address. Thanks to Leonardo Rodrigues for spotting
1151 this and testing the fix.
1153 Fix weird bug which sometimes omitted certain characters
1154 from the start of quoted strings in dhcp-options. Thanks
1155 to Dayton Turner for spotting the problem.
1157 Add facility to redirect some domains to the standard
1158 upstream servers: this allows something like
1159 --server=/google.com/1.2.3.4 --server=/www.google.com/#
1160 which will send queries for *.google.com to 1.2.3.4,
1161 except *www.google.com which will be forwarded as usual.
1162 Thanks to AJ Weber for prompting this addition.
1164 Improve the hash-algorithm used to generate IP addresses
1165 from MAC addresses during initial DHCP address
1166 allocation. This improves performance when large numbers
1167 of hosts with similar MAC addresses all try and get an IP
1168 address at the same time. Thanks to Paul Smith for his
1171 Tweak DHCP code so that --bridge-interface can be used to
1172 select which IP alias of an interface should be used for
1173 DHCP purposes on Linux. If eth0 has an alias eth0:dhcp
1174 then adding --bridge-interface=eth0:dhcp,eth0 will use
1175 the address of eth0:dhcp to determine the correct subnet
1176 for DHCP address allocation. Thanks to Pawel Golaszewski
1177 for prompting this and Eric Cooper for further testing.
1179 Add --dhcp-generate-names. Suggestion by Ferenc Wagner.
1181 Tweak DNS server selection algorithm when there is more
1182 than one server available for a domain, eg.
1183 --server=/mydomain/1.1.1.1
1184 --server=/mydomain/2.2.2.2
1185 Thanks to Alberto Cuesta-Canada for spotting a weakness
1188 Add --max-ttl. Thanks to Fredrik Ringertz for the patch.
1190 Allow --log-facility=- to force all logging to
1191 stderr. Suggestion from Clemens Fischer.
1193 Fix regression which caused configuration like
1194 --address=/.domain.com/1.2.3.4 to be rejected. The dot to the
1195 left of the domain has been implied and not required for a
1196 long time, but it should be accepted for backward
1197 compatibility. Thanks to Andrew Burcin for spotting this.
1199 Add --rebind-domain-ok and --rebind-localhost-ok.
1200 Suggestion from Clemens Fischer.
1202 Log replies to queries of type TXT, when --log-queries
1205 Fix compiler warnings when compiled with -DNO_DHCP. Thanks
1206 to Shantanu Gadgil for the patch.
1208 Updated French translation. Thanks to Gildas Le Nadan.
1210 Updated Polish translation. Thanks to Jan Psota.
1212 Updated German translation. Thanks to Matthias Andree.
1214 Added contrib/static-arp, thanks to Darren Hoo.
1216 Fix corruption of the domain when a name from /etc/hosts
1217 overrides one supplied by a DHCP client. Thanks to Fedor
1218 Kozhevnikov for spotting the problem.
1220 Updated Spanish translation. Thanks to Chris Chatham.
1224 Work around a Linux kernel bug which insists that the
1225 length of the option passed to setsockopt must be at least
1226 sizeof(int) bytes, even if we're calling SO_BINDTODEVICE
1227 and the device name is "lo". Note that this is fixed
1228 in kernel 2.6.31, but the workaround is harmless and
1229 allows earlier kernels to be used. Also fix dnsmasq
1230 bug which reported the wrong address when this failed.
1231 Thanks to Fedor for finding this.
1233 The API for IPv6 PKTINFO changed around Linux kernel
1234 2.6.14. Workaround the case where dnsmasq is compiled
1235 against newer headers, but then run on an old kernel:
1236 necessary for some *WRT distros.
1238 Re-read the set of network interfaces when re-loading
1239 /etc/resolv.conf if --bind-interfaces is not set. This
1240 handles the case that loopback interfaces do not exist
1241 when dnsmasq is first started.
1243 Tweak the PXE code to support port 4011. This should
1244 reduce broadcasts and make things more reliable when other
1245 servers are around. It also improves inter-operability
1246 with certain clients.
1248 Make a pxe-service configuration with no filename or boot
1249 service type legal: this does a local boot. eg.
1250 pxe-service=x86PC, "Local boot"
1252 Be more conservative in detecting "A for A"
1253 queries. Dnsmasq checks if the name in a type=A query looks
1254 like a dotted-quad IP address and answers the query itself
1255 if so, rather than forwarding it. Previously dnsmasq
1256 relied in the library function inet_addr() to convert
1257 addresses, and that will accept some things which are
1258 confusing in this context, like 1.2.3 or even just
1259 1234. Now we only do A for A processing for four decimal
1260 numbers delimited by dots.
1262 A couple of tweaks to fix compilation on Solaris. Thanks
1263 to Joel Macklow for help with this.
1265 Another Solaris compilation tweak, needed for Solaris
1266 2009.06. Thanks to Lee Essen for that.
1268 Added extract packaging stuff from Lee Essen to
1271 Increased the default limit on number of leases to 1000
1272 (from 150). This is mainly a defence against DoS attacks,
1273 and for the average "one for two class C networks"
1274 installation, IP address exhaustion does that just as
1275 well. Making the limit greater than the number of IP
1276 addresses available in such an installation removes a
1277 surprise which otherwise can catch people out.
1279 Removed extraneous trailing space in the value of the
1280 DNSMASQ_TIME_REMAINING DNSMASQ_LEASE_LENGTH and
1281 DNSMASQ_LEASE_EXPIRES environment variables. Thanks to
1282 Gildas Le Nadan for spotting this.
1284 Provide the network-id tags for a DHCP transaction to
1285 the lease-change script in the environment variable
1286 DNSMASQ_TAGS. A good suggestion from Gildas Le Nadan.
1288 Add support for RFC3925 "Vendor-Identifying Vendor
1289 Options". The syntax looks like this:
1290 --dhcp-option=vi-encap:<enterprise number>, .........
1292 Add support to --dhcp-match to allow matching against
1293 RFC3925 "Vendor-Identifying Vendor Classes". The syntax
1295 --dhcp-match=tag,vi-encap<enterprise number>, <value>
1297 Add some application specific code to assist in
1298 implementing the Broadband forum TR069 CPE-WAN
1299 specification. The details are in contrib/CPE-WAN/README
1301 Increase the default DNS packet size limit to 4096, as
1302 recommended by RFC5625 section 4.4.3. This can be
1303 reconfigured using --edns-packet-max if needed. Thanks to
1304 Francis Dupont for pointing this out.
1306 Rewrite query-ids even for TSIG signed packets, since
1307 this is allowed by RFC5625 section 4.5.
1309 Use getopt_long by default on OS X. It has been supported
1310 since version 10.3.0. Thanks to Arek Dreyer for spotting
1313 Added up-to-date startup configuration for MacOSX/launchd
1314 in contrib/MacOSX-launchd. Thanks to Arek Dreyer for
1317 Fix link error when including Dbus but excluding DHCP.
1318 Thanks to Oschtan for the bug report.
1320 Updated French translation. Thanks to Gildas Le Nadan.
1322 Updated Polish translation. Thanks to Jan Psota.
1324 Updated Spanish translation. Thanks to Chris Chatham.
1326 Fixed confusion about domains, when looking up DHCP hosts
1327 in /etc/hosts. This could cause spurious "Ignoring
1328 domain..." messages. Thanks to Fedor Kozhevnikov for
1329 finding and analysing the problem.
1333 Add support for internationalised DNS. Non-ASCII characters
1334 in domain names found in /etc/hosts, /etc/ethers and
1335 /etc/dnsmasq.conf will be correctly handled by translation to
1336 punycode, as specified in RFC3490. This function is only
1337 available if dnsmasq is compiled with internationalisation
1338 support, and adds a dependency on GNU libidn. Without i18n
1339 support, dnsmasq continues to be compilable with just
1340 standard tools. Thanks to Yves Dorfsman for the
1343 Add two more environment variables for lease-change scripts:
1344 First, DNSMASQ_SUPPLIED_HOSTNAME; this is set to the hostname
1345 supplied by a client, even if the actual hostname used is
1346 over-ridden by dhcp-host or dhcp-ignore-names directives.
1347 Also DNSMASQ_RELAY_ADDRESS which gives the address of
1348 a DHCP relay, if used.
1349 Suggestions from Michael Rack.
1351 Fix regression which broke echo of relay-agent
1352 options. Thanks to Michael Rack for spotting this.
1354 Don't treat option 67 as being interchangeable with
1355 dhcp-boot parameters if it's specified as
1358 Make the code to call scripts on lease-change compile-time
1359 optional. It can be switched off by editing src/config.h
1360 or building with "make COPTS=-DNO_SCRIPT".
1362 Make the TFTP server cope with filenames from Windows/DOS
1363 which use '\' as pathname separator. Thanks to Ralf for
1366 Updated Polish translation. Thanks to Jan Psota.
1368 Warn if an IP address is duplicated in /etc/ethers. Thanks
1369 to Felix Schwarz for pointing this out.
1371 Teach --conf-dir to take an option list of file suffices
1372 which will be ignored when scanning the directory. Useful
1373 for backup files etc. Thanks to Helmut Hullen for the
1376 Add new DHCP option named tftpserver-address, which
1377 corresponds to the third argument of dhcp-boot. This
1378 allows the complete functionality of dhcp-boot to be
1379 replicated with dhcp-option. Useful when using
1382 Test which upstream nameserver to use every 10 seconds
1383 or 50 queries and not just when a query times out and
1384 is retried. This should improve performance when there
1385 is a slow nameserver in the list. Thanks to Joe for the
1388 Don't do any PXE processing, even for clients with the
1389 correct vendorclass, unless at least one pxe-prompt or
1390 pxe-service option is given. This stops dnsmasq
1391 interfering with proxy PXE subsystems when it is just
1392 the DHCP server. Thanks to Spencer Clark for spotting this.
1394 Limit the blocksize used for TFTP transfers to a value
1395 which avoids packet fragmentation, based on the MTU of the
1396 local interface. Many netboot ROMs can't cope with
1399 Honour dhcp-ignore configuration for PXE and proxy-PXE
1400 requests. Thanks to Niels Basjes for the bug report.
1402 Updated French translation. Thanks to Gildas Le Nadan.
1406 Fix security problem which allowed any host permitted to
1407 do TFTP to possibly compromise dnsmasq by remote buffer
1408 overflow when TFTP enabled. Thanks to Core Security
1409 Technologies and Iván Arce, Pablo Hernán Jorge, Alejandro
1410 Pablo Rodriguez, Martín Coco, Alberto Soliño Testa and
1411 Pablo Annetta. This problem has Bugtraq id: 36121
1414 Fix a problem which allowed a malicious TFTP client to
1415 crash dnsmasq. Thanks to Steve Grubb at Red Hat for
1416 spotting this. This problem has Bugtraq id: 36120 and
1421 Fix regression in 2.48 which disables the lease-change
1422 script. Thanks to Jose Luis Duran for spotting this.
1424 Log TFTP "file not found" errors. These were not logged,
1425 since a normal PXELinux boot generates many of them, but
1426 the lack of the messages seems to be more confusing than
1427 routinely seeing them when there is no real error.
1429 Update Spanish translation. Thanks to Chris Chatham.
1433 Archived the extensive, backwards, changelog to
1434 CHANGELOG.archive. The current changelog now runs from
1435 version 2.43 and runs conventionally.
1437 Fixed bug which broke binding of servers to physical
1438 interfaces when interface names were longer than four
1439 characters. Thanks to MURASE Katsunori for the patch.
1441 Fixed netlink code to check that messages come from the
1442 correct source, and not another userspace process. Thanks
1443 to Steve Grubb for the patch.
1445 Maintainability drive: removed bug and missing feature
1446 workarounds for some old platforms. Solaris 9, OpenBSD
1447 older than 4.1, Glibc older than 2.2, Linux 2.2.x and
1448 DBus older than 1.1.x are no longer supported.
1450 Don't read included configuration files more than once:
1451 allows complex configuration structures without problems.
1453 Mark log messages from the various subsystems in dnsmasq:
1454 messages from the DHCP subsystem now have the ident string
1455 "dnsmasq-dhcp" and messages from TFTP have ident
1456 "dnsmasq-tftp". Thanks to Olaf Westrik for the patch.
1458 Fix possible infinite DHCP protocol loop when an IP
1459 address nailed to a hostname (not a MAC address) and a
1460 host sometimes provides the name, sometimes not.
1462 Allow --addn-hosts to take a directory: all the files
1463 in the directory are read. Thanks to Phil Cornelius for
1466 Support --bridge-interface on all platforms, not just BSD.
1468 Added support for advanced PXE functions. It's now
1469 possible to define a prompt and menu options which will
1470 be displayed when a client PXE boots. It's also possible to
1471 hand-off booting to other boot servers. Proxy-DHCP, where
1472 dnsmasq just supplies the PXE information and another DHCP
1473 server does address allocation, is also allowed. See the
1474 --pxe-prompt and --pxe-service keywords. Thanks to
1475 Alkis Georgopoulos for the suggestion and Guilherme Moro
1476 and Michael Brown for assistance.
1478 Improvements to DHCP logging. Thanks to Tom Metro for
1481 Add ability to build dnsmasq without DHCP support. To do
1482 this, edit src/config.h or build with
1483 "make COPTS=-DNO_DHCP". Thanks to Mahavir Jain for the patch.
1485 Added --test command-line switch - syntax check
1486 configuration files only.
1488 Updated French translation. Thanks to Gildas Le Nadan.
1492 Updated French translation. Thanks to Gildas Le Nadan.
1494 Fixed interface enumeration code to work on NetBSD
1495 5.0. Thanks to Roy Marples for the patch.
1497 Updated config.h to use the same location for the lease
1498 file on NetBSD as the other *BSD variants. Also allow
1499 LEASEFILE and CONFFILE symbols to be overriden in CFLAGS.
1501 Handle duplicate address detection on IPv6 more
1502 intelligently. In IPv6, an interface can have an address
1503 which is not usable, because it is still undergoing DAD
1504 (such addresses are marked "tentative"). Attempting to
1505 bind to an address in this state returns an error,
1506 EADDRNOTAVAIL. Previously, on getting such an error,
1507 dnsmasq would silently abandon the address, and never
1508 listen on it. Now, it retries once per second for 20
1509 seconds before generating a fatal error. 20 seconds should
1510 be long enough for any DAD process to complete, but can be
1511 adjusted in src/config.h if necessary. Thanks to Martin
1512 Krafft for the bug report.
1514 Add DBus introspection. Patch from Jeremy Laine.
1516 Update Dbus configuration file. Patch from Colin Walters.
1518 http://bugs.freedesktop.org/show_bug.cgi?id=18961
1520 Support arbitrarily encapsulated DHCP options, suggestion
1521 and initial patch from Samium Gromoff. This is useful for
1522 (eg) gPXE, which expect all its private options to be
1523 encapsulated inside a single option 175. So, eg,
1525 dhcp-option = encap:175, 190, "iscsi-client0"
1526 dhcp-option = encap:175, 191, "iscsi-client0-secret"
1528 will provide iSCSI parameters to gPXE.
1530 Enhance --dhcp-match to allow testing of the contents of a
1531 client-sent option, as well as its presence. This
1532 application in mind for this is RFC 4578
1533 client-architecture specifiers, but it's generally useful.
1534 Joey Korkames suggested the enhancement.
1536 Move from using the IP_XMIT_IF ioctl to IP_BOUND_IF on
1537 OpenSolaris. Thanks to Bastian Machek for the heads-up.
1539 No longer complain about blank lines in
1540 /etc/ethers. Thanks to Jon Nelson for the patch.
1542 Fix binding of servers to physical devices, eg
1543 --server=/domain/1.2.3.4@eth0 which was broken from 2.43
1544 onwards unless --query-port=0 set. Thanks to Peter Naulls
1547 Reply to DHCPINFORM requests even when the supplied ciaddr
1548 doesn't fall in any dhcp-range. In this case it's not
1549 possible to supply a complete configuration, but
1550 individually-configured options (eg PAC) may be useful.
1552 Allow the source address of an alias to be a range:
1553 --alias=192.168.0.0,10.0.0.0,255.255.255.0 maps the whole
1554 subnet 192.168.0.0->192.168.0.255 to 10.0.0.0->10.0.0.255,
1556 --alias=192.168.0.10-192.168.0.40,10.0.0.0,255.255.255.0
1557 maps only the 192.168.0.10->192.168.0.40 region. Thanks to
1558 Ib Uhrskov for the suggestion.
1560 Don't dynamically allocate DHCP addresses which may break
1561 Windows. Addresses which end in .255 or .0 are broken in
1562 Windows even when using supernetting.
1563 --dhcp-range=192.168.0.1,192.168.1.254,255,255,254.0 means
1564 192.168.0.255 is a valid IP address, but not for Windows.
1565 See Microsoft KB281579. We therefore no longer allocate
1566 these addresses to avoid hard-to-diagnose problems.
1568 Update Polish translation. Thanks to Jan Psota.
1570 Delete the PID-file when dnsmasq shuts down. Note that by
1571 this time, dnsmasq is normally not running as root, so
1572 this will fail if the PID-file is stored in a root-owned
1573 directory; such failure is silently ignored. To take
1574 advantage of this feature, the PID-file must be stored in a
1575 directory owned and write-able by the user running
1580 Allow --bootp-dynamic to take a netid tag, so that it may
1581 be selectively enabled. Thanks to Olaf Westrik for the
1584 Remove ISC-leasefile reading code. This has been
1585 deprecated for a long time, and last time I removed it, it
1586 ended up going back by request of one user. This time,
1587 it's gone for good; otherwise it would need to be
1588 re-worked to support multiple domains (see below).
1590 Support DHCP clients in multiple DNS domains. This is a
1591 long-standing request. Clients are assigned to a domain
1592 based in their IP address.
1594 Add --dhcp-fqdn flag, which changes behaviour if DNS names
1595 assigned to DHCP clients. When this is set, there must be
1596 a domain associated with each client, and only
1597 fully-qualified domain names are added to the DNS. The
1598 advantage is that the only the FQDN needs to be unique,
1599 so that two or more DHCP clients can share a hostname, as
1600 long as they are in different domains.
1602 Set environment variable DNSMASQ_DOMAIN when invoking
1603 lease-change script. This may be useful information to
1604 have now that it's variable.
1606 Tighten up data-checking code for DNS packet
1607 handling. Thanks to Steve Dodd who found certain illegal
1608 packets which could crash dnsmasq. No memory overwrite was
1609 possible, so this is not a security issue beyond the DoS
1612 Update example config dhcp option 47, the previous
1613 suggestion generated an illegal, zero-length,
1614 option. Thanks to Matthias Andree for finding this.
1616 Rewrite hosts-file reading code to remove the limit of
1617 1024 characters per line. John C Meuser found this.
1619 Create a net-id tag with the name of the interface on
1620 which the DHCP request was received.
1622 Fixed minor memory leak in DBus code, thanks to Jeremy
1623 Laine for the patch.
1625 Emit DBus signals as the DHCP lease database
1626 changes. Thanks to Jeremy Laine for the patch.
1628 Allow for more that one MAC address in a dhcp-host
1629 line. This configuration tells dnsmasq that it's OK to
1630 abandon a DHCP lease of the fixed address to one MAC
1631 address, if another MAC address in the dhcp-host statement
1632 asks for an address. This is useful to give a fixed
1633 address to a host which has two network interfaces
1634 (say, a laptop with wired and wireless interfaces.)
1635 It's very important to ensure that only one interface
1636 at a time is up, since dnsmasq abandons the first lease
1637 and re-uses the address before the leased time has
1638 elapsed. John Gray suggested this.
1640 Tweak the response to a DHCP request packet with a wrong
1641 server-id when --dhcp-authoritative is set; dnsmasq now
1642 returns a DHCPNAK, rather than silently ignoring the
1643 packet. Thanks to Chris Marget for spotting this
1646 Add --cname option. This provides a limited alias
1647 function, usable for DHCP names. Thanks to AJ Weber for
1648 suggestions on this.
1650 Updated contrib/webmin with latest version from Neil
1653 Updated Polish translation. Thanks to Jan Psota.
1655 Correct the text names for DHCP options 64 and 65 to be
1656 "nis+-domain" and "nis+-servers".
1658 Updated Spanish translation. Thanks to Chris Chatham.
1660 Force re-reading of /etc/resolv.conf when an "interface
1665 Fix total DNS failure in release 2.44 unless --min-port
1666 specified. Thanks to Steven Barth and Grant Coady for
1667 bugreport. Also reject out-of-range port spec, which could
1668 break things too: suggestion from Gilles Espinasse.
1672 Fix crash when unknown client attempts to renew a DHCP
1673 lease, problem introduced in version 2.43. Thanks to
1674 Carlos Carvalho for help chasing this down.
1676 Fix potential crash when a host which doesn't have a lease
1677 does DHCPINFORM. Again introduced in 2.43. This bug has
1678 never been reported in the wild.
1680 Fix crash in netlink code introduced in 2.43. Thanks to
1681 Jean Wolter for finding this.
1683 Change implementation of min_port to work even if min-port
1686 Patch to enable compilation of latest Mac OS X. Thanks to
1689 Update Spanish translation. Thanks to Christopher Chatham.
1693 Updated Polish translation. Thanks to Jan Psota.
1695 Flag errors when configuration options are repeated
1698 Further tweaks for GNU/kFreeBSD
1700 Add --no-wrap to msgmerge call - provides nicer .po file
1703 Honour lease-time spec in dhcp-host lines even for
1704 BOOTP. The user is assumed to known what they are doing in
1705 this case. (Hosts without the time spec still get infinite
1706 leases for BOOTP, over-riding the default in the
1707 dhcp-range.) Thanks to Peter Katzmann for uncovering this.
1709 Fix problem matching relay-agent ids. Thanks to Michael
1710 Rack for the bug report.
1712 Add --naptr-record option. Suggestion from Johan
1715 Implement RFC 5107 server-id-override DHCP relay agent
1718 Apply patches from Stefan Kruger for compilation on
1719 Solaris 10 under Sun studio.
1721 Yet more tweaking of Linux capability code, to suppress
1722 pointless wingeing from kernel 2.6.25 and above.
1724 Improve error checking during startup. Previously, some
1725 errors which occurred during startup would be worked
1726 around, with dnsmasq still starting up. Some were logged,
1727 some silent. Now, they all cause a fatal error and dnsmasq
1728 terminates with a non-zero exit code. The errors are those
1729 associated with changing uid and gid, setting process
1730 capabilities and writing the pidfile. Thanks to Uwe
1731 Gansert and the Suse security team for pointing out
1732 this improvement, and Bill Reimers for good implementation
1735 Provide NO_LARGEFILE compile option to switch off largefile
1736 support when compiling against versions of uclibc which
1737 don't support it. Thanks to Stephane Billiart for the patch.
1739 Implement random source ports for interactions with
1740 upstream nameservers. New spoofing attacks have been found
1741 against nameservers which do not do this, though it is not
1742 clear if dnsmasq is vulnerable, since to doesn't implement
1743 recursion. By default dnsmasq will now use a different
1744 source port (and socket) for each query it sends
1745 upstream. This behaviour can suppressed using the
1746 --query-port option, and the old default behaviour
1747 restored using --query-port=0. Explicit source-port
1748 specifications in --server configs are still honoured.
1750 Replace the random number generator, for better
1751 security. On most BSD systems, dnsmasq uses the
1752 arc4random() RNG, which is secure, but on other platforms,
1753 it relied on the C-library RNG, which may be
1754 guessable and therefore allow spoofing. This release
1755 replaces the libc RNG with the SURF RNG, from Daniel
1756 J. Berstein's DJBDNS package.
1758 Don't attempt to change user or group or set capabilities
1759 if dnsmasq is run as a non-root user. Without this, the
1760 change from soft to hard errors when these fail causes
1761 problems for non-root daemons listening on high
1762 ports. Thanks to Patrick McLean for spotting this.
1764 Updated French translation. Thanks to Gildas Le Nadan.
1768 The changelog for version 2.42 and earlier is
1769 available in CHANGELOG.archive.
