2 Fix crash at startup when an empty suffix is supplied to
3 --conf-dir, also trivial memory leak. Thanks to
4 Tomas Hozza for spotting this.
6 Remove floor of 4096 on advertised EDNS0 packet size when
7 DNSSEC in use, the original rationale for this has long gone.
8 Thanks to Anders Kaseorg for spotting this.
10 Use inotify for checking on updates to /etc/resolv.conf and
11 friends under Linux. This fixes race conditions when the files are
12 updated rapidly and saves CPU by noy polling. To build
13 a binary that runs on old Linux kernels without inotify,
14 use make COPTS=-DNO_INOTIFY
16 Fix breakage of --domain=<domain>,<subnet>,local - only reverse
17 queries were intercepted. THis appears to have been broken
18 since 2.69. Thanks to Josh Stone for finding the bug.
20 Eliminate IPv6 privacy addresses and deprecated addresses from
21 the answers given by --interface-name. Note that reverse queries
22 (ie looking for names, given addresses) are not affected.
23 Thanks to Michael Gorbach for the suggestion.
25 Fix crash in DNSSEC code with long RRs. Thanks to Marco Davids
28 Add --ignore-address option. Ignore replies to A-record
29 queries which include the specified address. No error is
30 generated, dnsmasq simply continues to listen for another
31 reply. This is useful to defeat blocking strategies which
32 rely on quickly supplying a forged answer to a DNS
33 request for certain domains, before the correct answer can
34 arrive. Thanks to Glen Huang for the patch.
36 Revisit the part of DNSSEC validation which determines if an
37 unsigned answer is legit, or is in some part of the DNS
38 tree which should be signed. Dnsmasq now works from the
39 DNS root downward looking for the limit of signed
40 delegations, rather than working bottom up. This is
41 both more correct, and less likely to trip over broken
42 nameservers in the unsigned parts of the DNS tree
43 which don't respond well to DNSSEC queries.
45 Add --log-queries=extra option, which makes logs easier
46 to search automatically.
48 Add --min-cache-ttl option. I've resisted this for a long
49 time, on the grounds that disbelieving TTLs is never a
50 good idea, but I've been persuaded that there are
51 sometimes reasons to do it. (Step forward, GFW).
52 To avoid misuse, there's a hard limit on the TTL
53 floor of one hour. Thansk to RinSatsuki for the patch.
55 Cope with multiple interfaces with the same link-local
56 address. (IPv6 addresses are scoped, so this is allowed.)
57 Thanks to Cory Benfield for help with this.
59 Add --dhcp-hostsdir. This allows addition of new host
60 configurations to a running dnsmasq instance much more
61 cheaply than having dnsmasq re-read all its existing
62 configuration each time.
64 Don't reply to DHCPv6 SOLICIT messages if we're not
65 configured to do stateful DHCPv6. Thanks to Win King Wan
68 Fix broken DNSSEC validation of ECDSA signatures.
72 Add ra-advrouter mode, for RFC-3775 mobile IPv6 support.
74 Add support for "ipsets" in *BSD, using pf. Thanks to
75 Sven Falempim for the patch.
77 Fix race condition which could lock up dnsmasq when an
78 interface goes down and up rapidly. Thanks to Conrad
79 Kostecki for helping to chase this down.
81 Add DBus methods SetFilterWin2KOption and SetBogusPrivOption
82 Thanks to the Smoothwall project for the patch.
84 Fix failure to build against Nettle-3.0. Thanks to Steven
85 Barth for spotting this and finding the fix.
87 When assigning existing DHCP leases to intefaces by comparing
88 networks, handle the case that two or more interfaces have the
89 same network part, but different prefix lengths (favour the
90 longer prefix length.) Thanks to Lung-Pin Chang for the
93 Add a mode which detects and removes DNS forwarding loops, ie
94 a query sent to an upstream server returns as a new query to
95 dnsmasq, and would therefore be forwarded again, resulting in
96 a query which loops many times before being dropped. Upstream
97 servers which loop back are disabled and this event is logged.
98 Thanks to Smoothwall for their sponsorship of this feature.
100 Extend --conf-dir to allow filtering of files. So
101 --conf-dir=/etc/dnsmasq.d,\*.conf
102 will load all the files in /etc/dnsmasq.d which end in .conf
104 Fix bug when resulted in NXDOMAIN answers instead of NODATA in
107 Fix bug which caused dnsmasq to become unresponsive if it
108 failed to send packets due to a network interface disappearing.
109 Thanks to Niels Peen for spotting this.
111 Fix problem with --local-service option on big-endian platforms
112 Thanks to Richard Genoud for the patch.
116 Subtle change to error handling to help DNSSEC validation
117 when servers fail to provide NODATA answers for
118 non-existent DS records.
120 Tweak code which removes DNSSEC records from answers when
121 not required. Fixes broken answers when additional section
122 has real records in it. Thanks to Marco Davids for the bug
125 Fix DNSSEC validation of ANY queries. Thanks to Marco Davids
126 for spotting that too.
128 Fix total DNS failure and 100% CPU use if cachesize set to zero,
129 regression introduced in 2.69. Thanks to James Hunt and
130 the Ubuntu crowd for assistance in fixing this.
134 Fix crash, introduced in 2.69, on TCP request when dnsmasq
135 compiled with DNSSEC support, but running without DNSSEC
136 enabled. Thanks to Manish Sing for spotting that one.
138 Fix regression which broke ipset functionality. Thanks to
139 Wang Jian for the bug report.
143 Implement dynamic interface discovery on *BSD. This allows
144 the contructor: syntax to be used in dhcp-range for DHCPv6
145 on the BSD platform. Thanks to Matthias Andree for
146 valuable research on how to implement this.
148 Fix infinite loop associated with some --bogus-nxdomain
149 configs. Thanks fogobogo for the bug report.
151 Fix missing RA RDNS option with configuration like
152 --dhcp-option=option6:23,[::] Thanks to Tsachi Kimeldorfer
153 for spotting the problem.
155 Add [fd00::] and [fe80::] as special addresses in DHCPv6
156 options, analogous to [::]. [fd00::] is replaced with the
157 actual ULA of the interface on the machine running
158 dnsmasq, [fe80::] with the link-local address.
159 Thanks to Tsachi Kimeldorfer for championing this.
161 DNSSEC validation and caching. Dnsmasq needs to be
162 compiled with this enabled, with
164 make dnsmasq COPTS=-DHAVE_DNSSEC
166 this add dependencies on the nettle crypto library and the
167 gmp maths library. It's possible to have these linked
170 make dnsmasq COPTS='-DHAVE_DNSSEC -DHAVE_DNSSEC_STATIC'
172 which bloats the dnsmasq binary, but saves the size of
173 the shared libraries which are much bigger.
175 To enable, DNSSEC, you will need a set of
176 trust-anchors. Now that the TLDs are signed, this can be
177 the keys for the root zone, and for convenience they are
178 included in trust-anchors.conf in the dnsmasq
179 distribution. You should of course check that these are
180 legitimate and up-to-date. So, adding
182 conf-file=/path/to/trust-anchors.conf
185 to your config is all thats needed to get things
186 working. The upstream nameservers have to be DNSSEC-capable
187 too, of course. Many ISP nameservers aren't, but the
188 Google public nameservers (8.8.8.8 and 8.8.4.4) are.
189 When DNSSEC is configured, dnsmasq validates any queries
190 for domains which are signed. Query results which are
191 bogus are replaced with SERVFAIL replies, and results
192 which are correctly signed have the AD bit set. In
193 addition, and just as importantly, dnsmasq supplies
194 correct DNSSEC information to clients which are doing
195 their own validation, and caches DNSKEY, DS and RRSIG
196 records, which significantly improve the performance of
197 downstream validators. Setting --log-queries will show
200 If a domain is returned from an upstream nameserver without
201 DNSSEC signature, dnsmasq by default trusts this. This
202 means that for unsigned zone (still the majority) there
203 is effectively no cost for having DNSSEC enabled. Of course
204 this allows an attacker to replace a signed record with a
205 false unsigned record. This is addressed by the
206 --dnssec-check-unsigned flag, which instructs dnsmasq
207 to prove that an unsigned record is legitimate, by finding
208 a secure proof that the zone containing the record is not
209 signed. Doing this has costs (typically one or two extra
210 upstream queries). It also has a nasty failure mode if
211 dnsmasq's upstream nameservers are not DNSSEC capable.
212 Without --dnssec-check-unsigned using such an upstream
213 server will simply result in not queries being validated;
214 with --dnssec-check-unsigned enabled and a
215 DNSSEC-ignorant upstream server, _all_ queries will fail.
217 Note that DNSSEC requires that the local time is valid and
218 accurate, if not then DNSSEC validation will fail. NTP
219 should be running. This presents a problem for routers
220 without a battery-backed clock. To set the time needs NTP
221 to do DNS lookups, but lookups will fail until NTP has run.
222 To address this, there's a flag, --dnssec-no-timecheck
223 which disables the time checks (only) in DNSSEC. When dnsmasq
224 is started and the clock is not synced, this flag should
225 be used. As soon as the clock is synced, SIGHUP dnsmasq.
226 The SIGHUP clears the cache of partially-validated data and
227 resets the no-timecheck flag, so that all DNSSEC checks
228 henceforward will be complete.
230 The development of DNSSEC in dnsmasq was started by
231 Giovanni Bajo, to whom huge thanks are owed. It has been
232 supported by Comcast, whose techfund grant has allowed for
233 an invaluable period of full-time work to get it to
236 Add --rev-server. Thanks to Dave Taht for suggesting this.
238 Add --servers-file. Allows dynamic update of upstream servers
239 full access to configuration.
241 Add --local-service. Accept DNS queries only from hosts
242 whose address is on a local subnet, ie a subnet for which
243 an interface exists on the server. This option
244 only has effect if there are no --interface --except-interface,
245 --listen-address or --auth-server options. It is intended
246 to be set as a default on installation, to allow
247 unconfigured installations to be useful but also safe from
248 being used for DNS amplification attacks.
250 Fix crashes in cache_get_cname_target() when dangling CNAMEs
251 encountered. Thanks to Andy and the rt-n56u project for
252 find this and helping to chase it down.
254 Fix wrong RCODE in authoritative DNS replies to PTR queries. The
255 correct answer was included, but the RCODE was set to NXDOMAIN.
256 Thanks to Craig McQueen for spotting this.
258 Make statistics available as DNS queries in the .bind TLD as
259 well as logging them.
263 Use random addresses for DHCPv6 temporary address
264 allocations, instead of algorithmically determined stable
267 Fix bug which meant that the DHCPv6 DUID was not available
268 in DHCP script runs during the lifetime of the dnsmasq
269 process which created the DUID de-novo. Once the DUID was
270 created and stored in the lease file and dnsmasq
271 restarted, this bug disappeared.
273 Fix bug introduced in 2.67 which could result in erroneous
274 NXDOMAIN returns to CNAME queries.
276 Fix build failures on MacOS X and openBSD.
278 Allow subnet specifications in --auth-zone to be interface
279 names as well as address literals. This makes it possible
280 to configure authoritative DNS when local address ranges
281 are dynamic and works much better than the previous
282 work-around which exempted contructed DHCP ranges from the
283 IP address filtering. As a consequence, that work-around
284 is removed. Under certain circumstances, this change wil
285 break existing configuration: if you're relying on the
286 contructed-range exception, you need to change --auth-zone
287 to specify the same interface as is used to construct your
288 DHCP ranges, probably with a trailing "/6" like this:
289 --auth-zone=example.com,eth0/6 to limit the addresses to
290 IPv6 addresses of eth0.
292 Fix problems when advertising deleted IPv6 prefixes. If
293 the prefix is deleted (rather than replaced), it doesn't
294 get advertised with zero preferred time. Thanks to Tsachi
297 Fix segfault with some locally configured CNAMEs. Thanks
298 to Andrew Childs for spotting the problem.
300 Fix memory leak on re-reading /etc/hosts and friends,
303 Check the arrival interface of incoming DNS and TFTP
304 requests via IPv6, even in --bind-interfaces mode. This
305 isn't possible for IPv4 and can generate scary warnings,
306 but as it's always possible for IPv6 (the API always
307 exists) then we should do it always.
309 Tweak the rules on prefix-lengths in --dhcp-range for
310 IPv6. The new rule is that the specified prefix length
311 must be larger than or equal to the prefix length of the
312 corresponding address on the local interface.
316 Fix crash if upstream server returns SERVFAIL when
317 --conntrack in use. Thanks to Giacomo Tazzari for finding
318 this and supplying the patch.
320 Repair regression in 2.64. That release stopped sending
321 lease-time information in the reply to DHCPINFORM
322 requests, on the correct grounds that it was a standards
323 violation. However, this broke the dnsmasq-specific
324 dhcp_lease_time utility. Now, DHCPINFORM returns
325 lease-time only if it's specifically requested
326 (maintaining standards) and the dhcp_lease_time utility
327 has been taught to ask for it (restoring functionality).
329 Fix --dhcp-match, --dhcp-vendorclass and --dhcp-userclass
330 to work with BOOTP and well as DHCP. Thanks to Peter
331 Korsgaard for spotting the problem.
333 Add --synth-domain. Thanks to Vishvananda Ishaya for
336 Fix failure to compile ipset.c if old kernel headers are
337 in use. Thanks to Eugene Rudoy for pointing this out.
339 Handle IPv4 interface-address labels in Linux. These are
340 often used to emulate the old IP-alias addresses. Before,
341 using --interface=eth0 would service all the addresses of
342 eth0, including ones configured as aliases, which appear
343 in ifconfig as eth0:0. Now, only addresses with the label
344 eth0 are active. This is not backwards compatible: if you
345 want to continue to bind the aliases too, you need to add
346 eg. --interface=eth0:0 to the config.
348 Fix "failed to set SO_BINDTODEVICE on DHCP socket: Socket
349 operation on non-socket" error on startup with
350 configurations which have exactly one --interface option
351 and do RA but _not_ DHCPv6. Thanks to Trever Adams for the
354 Generalise --interface-name to cope with IPv6 addresses
355 and multiple addresses per interface per address family.
357 Fix option parsing for --dhcp-host, which was generating a
358 spurious error when all seven possible items were
359 included. Thanks to Zhiqiang Wang for the bug report.
361 Remove restriction on prefix-length in --auth-zone. Thanks
362 to Toke Hoiland-Jorgensen for suggesting this.
364 Log when the maximum number of concurrent DNS queries is
365 reached. Thanks to Marcelo Salhab Brogliato for the patch.
367 If wildcards are used in --interface, don't assume that
368 there will only ever be one available interface for DHCP
369 just because there is one at start-up. More may appear, so
370 we can't use SO_BINDTODEVICE. Thanks to Natrio for the bug
373 Increase timeout/number of retries in TFTP to accomodate
374 AudioCodes Voice Gateways doing streaming writes to flash.
375 Thanks to Damian Kaczkowski for spotting the problem.
377 Fix crash with empty DHCP string options when adding zero
378 terminator. Thanks to Patrick McLean for the bug report.
380 Allow hostnames to start with a number, as allowed in
381 RFC-1123. Thanks to Kyle Mestery for the patch.
383 Fixes to DHCP FQDN option handling: don't terminate FQDN
384 if domain not known and allow a FQDN option with blank
385 name to request that a FQDN option is returned in the
386 reply. Thanks to Roy Marples for the patch.
388 Make --clear-on-reload apply to setting upstream servers
391 When the address which triggered the construction of an
392 advertised IPv6 prefix disappears, continue to advertise
393 the prefix for up to 2 hours, with the preferred lifetime
394 set to zero. This satisfies RFC 6204 4.3 L-13 and makes
395 things work better if a prefix disappears without being
396 deprecated first. Thanks to Uwe Schindler for persuasively
399 Fix MAC address enumeration on *BSD. Thanks to Brad Smith
402 Support RFC-4242 information-refresh-time options in the
403 reply to DHCPv6 information-request. The lease time of the
404 smallest valid dhcp-range is sent. Thanks to Uwe Schindler
407 Make --listen-address higher priority than --except-interface
408 in all circumstances. Thanks to Thomas Hood for the bugreport.
410 Provide independent control over which interfaces get TFTP
411 service. If enable-tftp is given a list of interfaces, then TFTP
412 is provided on those. Without the list, the previous behaviour
413 (provide TFTP to the same interfaces we provide DHCP to)
414 is retained. Thanks to Lonnie Abelbeck for the suggestion.
416 Add --dhcp-relay config option. Many thanks to vtsl.net
417 for sponsoring this development.
419 Fix crash with empty tag: in --dhcp-range. Thanks to
420 Kaspar Schleiser for the bug report.
422 Add "baseline" and "bloatcheck" makefile targets, for
423 revealing size changes during development. Thanks to
424 Vladislav Grishenko for the patch.
426 Cope with DHCPv6 clients which send REQUESTs without
427 address options - treat them as SOLICIT with rapid commit.
429 Support identification of clients by MAC address in
430 DHCPv6. When using a relay, the relay must support RFC
431 6939 for this to work. It always works for directly
432 connected clients. Thanks to Vladislav Grishenko
433 for prompting this feature.
435 Remove the rule for constructed DHCP ranges that the local
436 address must be either the first or last address in the
437 range. This was originally to avoid SLAAC addresses, but
438 we now explicitly autoconfig and privacy addresses instead.
440 Update Polish translation. Thanks to Jan Psota.
442 Fix problem in DHCPv6 vendorclass/userclass matching
443 code. Thanks to Tanguy Bouzeloc for the patch.
445 Update Spanish transalation. Thanks to Vicente Soriano.
447 Add --ra-param option. Thanks to Vladislav Grishenko for
450 Add --add-subnet configuration, to tell upstream DNS
451 servers where the original client is. Thanks to DNSthingy
452 for sponsoring this feature.
454 Add --quiet-dhcp, --quiet-dhcp6 and --quiet-ra. Thanks to
455 Kevin Darbyshire-Bryant for the initial patch.
457 Allow A/AAAA records created by --interface-name to be the
458 target of --cname. Thanks to Hadmut Danisch for the
461 Avoid treating a --dhcp-host which has an IPv6 address
462 as eligable for use with DHCPv4 on the grounds that it has
463 no address, and vice-versa. Thanks to Yury Konovalov for
464 spotting the problem.
466 Do a better job caching dangling CNAMEs. Thanks to Yves
467 Dorfsman for spotting the problem.
471 Add the ability to act as an authoritative DNS
472 server. Dnsmasq can now answer queries from the wider 'net
473 with local data, as long as the correct NS records are set
474 up. Only local data is provided, to avoid creating an open
475 DNS relay. Zone transfer is supported, to allow secondary
476 servers to be configured.
478 Add "constructed DHCP ranges" for DHCPv6. This is intended
479 for IPv6 routers which get prefixes dynamically via prefix
480 delegation. With suitable configuration, stateful DHCPv6
481 and RA can happen automatically as prefixes are delegated
482 and then deprecated, without having to re-write the
483 dnsmasq configuration file or restart the daemon. Thanks to
484 Steven Barth for extensive testing and development work on
487 Fix crash on startup on Solaris 11. Regression probably
488 introduced in 2.61. Thanks to Geoff Johnstone for the
491 Add code to make behaviour for TCP DNS requests that same
492 as for UDP requests, when a request arrives for an allowed
493 address, but via a banned interface. This change is only
494 active on Linux, since the relevant API is missing (AFAIK)
495 on other platforms. Many thanks to Tomas Hozza for
496 spotting the problem, and doing invaluable discovery of
497 the obscure and undocumented API required for the solution.
499 Don't send the default DHCP option advertising dnsmasq as
500 the local DNS server if dnsmasq is configured to not act
501 as DNS server, or it's configured to a non-standard port.
503 Add DNSMASQ_CIRCUIT_ID, DNSMASQ_SUBCRIBER_ID,
504 DNSMASQ_REMOTE_ID variables to the environment of the
505 lease-change script (and the corresponding Lua). These hold
506 information inserted into the DHCP request by a DHCP relay
507 agent. Thanks to Lakefield Communications for providing a
508 bounty for this addition.
510 Fixed crash, introduced in 2.64, whilst handling DHCPv6
511 information-requests with some common configurations.
512 Thanks to Robert M. Albrecht for the bug report and
515 Add --ipset option. Thanks to Jason A. Donenfeld for the
518 Don't erroneously reject some option names in --dhcp-match
519 options. Thanks to Benedikt Hochstrasser for the bug report.
521 Allow a trailing '*' wildcard in all interface-name
522 configurations. Thanks to Christian Parpart for the patch.
524 Handle the situation where libc headers define
525 SO_REUSEPORT, but the kernel in use doesn't, to cope with
526 the introduction of this option to Linux. Thanks to Rich
527 Felker for the bug report.
529 Update Polish translation. Thanks to Jan Psota.
531 Fix crash if the configured DHCP lease limit is
532 reached. Regression occurred in 2.61. Thanks to Tsachi for
535 Update the French translation. Thanks to Gildas le Nadan.
539 Fix regression which broke forwarding of queries sent via
540 TCP which are not for A and AAAA and which were directed to
541 non-default servers. Thanks to Niax for the bug report.
543 Fix failure to build with DHCP support excluded. Thanks to
544 Gustavo Zacarias for the patch.
546 Fix nasty regression in 2.64 which completely broke cacheing.
550 Handle DHCP FQDN options with all flag bits zero and
551 --dhcp-client-update set. Thanks to Bernd Krumbroeck for
552 spotting the problem.
554 Finesse the check for /etc/hosts names which conflict with
555 DHCP names. Previously a name/address pair in /etc/hosts
556 which didn't match the name/address of a DHCP lease would
557 generate a warning. Now that only happesn if there is not
558 also a match. This allows multiple addresses for a name in
559 /etc/hosts with one of them assigned via DHCP.
561 Fix broken vendor-option processing for BOOTP. Thanks to
562 Hans-Joachim Baader for the bug report.
564 Don't report spurious netlink errors, regression in
565 2.63. Thanks to Vladislav Grishenko for the patch.
567 Flag DHCP or DHCPv6 in starup logging. Thanks to
568 Vladislav Grishenko for the patch.
570 Add SetServersEx method in DBus interface. Thanks to Dan
571 Williams for the patch.
573 Add SetDomainServers method in DBus interface. Thanks to
574 Roy Marples for the patch.
576 Fix build with later Lua libraries. Thansk to Cristian
577 Rodriguez for the patch.
579 Add --max-cache-ttl option. Thanks to Dennis Kaarsemaker
582 Fix breakage of --host-record parsing, resulting in
583 infinte loop at startup. Regression in 2.63. Thanks to
584 Haim Gelfenbeyn for spotting this.
586 Set SO_REUSEADDRESS and SO_V6ONLY options on the DHCPv6
587 socket, this allows multiple instances of dnsmasq on a
588 single machine, in the same way as for DHCPv4. Thanks to
589 Gene Czarcinski and Vladislav Grishenko for work on this.
591 Fix DHCPv6 to do access control correctly when it's
592 configured with --listen-address. Thanks to
593 Gene Czarcinski for sorting this out.
595 Add a "wildcard" dhcp-range which works for any IPv6
596 subnet, --dhcp-range=::,static Useful for Stateless
597 DHCPv6. Thanks to Vladislav Grishenko for the patch.
599 Don't include lease-time in DHCPACK replies to DHCPINFORM
600 queries, since RFC-2131 says we shouldn't. Thanks to
601 Wouter Ibens for pointing this out.
603 Makefile tweak to do dependency checking on header files.
604 Thanks to Johan Peeters for the patch.
606 Check interface for outgoing unsolicited router
607 advertisements, rather than relying on interface address
608 configuration. Thanks to Gene Czarinski for the patch.
610 Handle better attempts to transmit on interfaces which are
611 still doing DAD, and specifically do not just transmit
612 without setting source address and interface, since this
613 can cause very puzzling effects when a router
614 advertisement goes astray. Thanks again to Gene Czarinski.
616 Get RA timers right when there is more than one
617 dhcp-range on a subnet.
621 Do duplicate dhcp-host address check in --test mode.
623 Check that tftp-root directories are accessible before
624 start-up. Thanks to Daniel Veillard for the initial patch.
626 Allow more than one --tfp-root flag. The per-interface
627 stuff is pointless without that.
629 Add --bind-dynamic. A hybrid mode between the default and
630 --bind-interfaces which copes with dynamically created
633 A couple of fixes to the build system for Android. Thanks
634 to Metin Kaya for the patches.
636 Remove the interface:<interface> argument in --dhcp-range, and
637 the interface argument to --enable-tftp. These were a
638 still-born attempt to allow automatic isolated
639 configuration by libvirt, but have never (to my knowledge)
640 been used, had very strange semantics, and have been
641 superceded by other mechanisms.
643 Fixed bug logging filenames when duplicate dhcp-host
644 addresses are found. Thanks to John Hanks for the patch.
646 Fix regression in 2.61 which broke caching of CNAME
647 chains. Thanks to Atul Gupta for the bug report.
649 Allow the target of a --cname flag to be another --cname.
651 Teach DHCPv6 about the RFC 4242 information-refresh-time
652 option, and add parsing if the minutes, hours and days
653 format for options. Thanks to Francois-Xavier Le Bail for
656 Allow "w" (for week) as multiplier in lease times, as well
657 as seconds, minutes, hours and days. Álvaro Gámez Machado
658 spotted the ommission.
660 Update French translation. Thanks to Gildas Le Nadan.
662 Allow a DBus service name to be given with --enable-dbus
663 which overrides the default,
664 uk.org.thekelleys.dnsmasq. Thanks to Mathieu
665 Trudel-Lapierre for the patch.
667 Set the "prefix on-link" bit in Router
668 Advertisements. Thanks to Gui Iribarren for the patch.
672 Update German translation. Thanks to Conrad Kostecki.
674 Cope with router-solict packets wich don't have a valid
675 source address. Thanks to Vladislav Grishenko for the patch.
677 Fixed bug which caused missing periodic router
678 advertisements with some configurations. Thanks to
679 Vladislav Grishenko for the patch.
681 Fixed bug which broke DHCPv6/RA with prefix lengths
682 which are not divisible by 8. Thanks to Andre Coetzee
685 Fix non-response to router-solicitations when
686 router-advertisement configured, but DHCPv6 not
687 configured. Thanks to Marien Zwart for the patch.
689 Add --dns-rr, to allow arbitrary DNS resource records.
691 Fixed bug which broke RA scheduling when an interface had
692 two addresses in the same network. Thanks to Jim Bos for
693 his help nailing this.
696 Re-write interface discovery code on *BSD to use
697 getifaddrs. This is more portable, more straightforward,
698 and allows us to find the prefix length for IPv6
701 Add ra-names, ra-stateless and slaac keywords for DHCPv6.
702 Dnsmasq can now synthesise AAAA records for dual-stack
703 hosts which get IPv6 addresses via SLAAC. It is also now
704 possible to use SLAAC and stateless DHCPv6, and to
705 tell clients to use SLAAC addresses as well as DHCP ones.
706 Thanks to Dave Taht for help with this.
708 Add --dhcp-duid to allow DUID-EN uids to be used.
710 Explicity send DHCPv6 replies to the correct port, instead
711 of relying on clients to send requests with the correct
712 source address, since at least one client in the wild gets
713 this wrong. Thanks to Conrad Kostecki for help tracking
716 Send a preference value of 255 in DHCPv6 replies when
717 --dhcp-authoritative is in effect. This tells clients not
718 to wait around for other DHCP servers.
720 Better logging of DHCPv6 options.
722 Add --host-record. Thanks to Rob Zwissler for the
725 Invoke the DHCP script with action "tftp" when a TFTP file
726 transfer completes. The size of the file, address to which
727 it was sent and complete pathname are supplied. Note that
728 version 2.60 introduced some script incompatibilties
729 associated with DHCPv6, and this is a further change. To
730 be safe, scripts should ignore unknown actions, and if
731 not IPv6-aware, should exit if the environment
732 variable DNSMASQ_IAID is set. The use-case for this is
733 to track netboot/install. Suggestion from Shantanu
736 Update contrib/port-forward/dnsmasq-portforward to reflect
739 Set the environment variable DNSMASQ_LOG_DHCP when running
740 the script id --log-dhcp is in effect, so that script can
741 taylor their logging verbosity. Suggestion from Malte
744 Arrange that addresses specified with --listen-address
745 work even if there is no interface carrying the
746 address. This is chiefly useful for IPv4 loopback
747 addresses, where any address in 127.0.0.0/8 is a valid
748 loopback address, but normally only 127.0.0.1 appears on
749 the lo interface. Thanks to Mathieu Trudel-Lapierre for
750 the idea and initial patch.
752 Fix crash, introduced in 2.60, when a DHCPINFORM is
753 received from a network which has no valid dhcp-range.
754 Thanks to Stephane Glondu for the bug report.
756 Add a new DHCP lease time keyword, "deprecated" for
757 --dhcp-range. This is only valid for IPv6, and sets the
758 preffered lease time for both DHCP and RA to zero. The
759 effect is that clients can continue to use the address
760 for existing connections, but new connections will use
761 other addresses, if they exist. This makes hitless
762 renumbering at least possible.
764 Fix bug in address6_available() which caused DHCPv6 lease
765 aquisition to fail if more than one dhcp-range in use.
767 Provide RDNSS and DNSSL data in router advertisements,
768 using the settings provided for DHCP options
769 option6:domain-search and option6:dns-server.
771 Tweak logo/favicon.ico to add some transparency. Thanks to
772 SamLT for work on this.
774 Don't cache data from non-recursive nameservers, since it
775 may erroneously look like a valid CNAME to a non-exitant
776 name. Thanks to Ben Winslow for finding this.
778 Call SO_BINDTODEVICE on the DHCP socket(s) when doing DHCP
779 on exactly one interface and --bind-interfaces is set. This
780 makes the OpenStack use-case of one dnsmasq per virtual
781 interface work. This is only available on Linux; it's not
782 supported on other platforms. Thanks to Vishvananda Ishaya
783 and the OpenStack team for the suggestion.
785 Updated French translation. Thanks to Gildas Le Nadan.
787 Give correct from-cache answers to explict CNAME queries.
788 Thanks to Rob Zwissler for spotting this.
790 Add --tftp-lowercase option. Thanks to Oliver Rath for the
793 Ensure that the DBus DhcpLeaseUpdated events are generated
794 when a lease goes through INIT_REBOOT state, even if the
795 dhcp-script is not in use. Thanks to Antoaneta-Ecaterina
798 Fix failure of TFTP over IPv4 on OpenBSD platform. Thanks
799 to Brad Smith for spotting this.
803 Fix compilation problem in Mac OS X Lion. Thanks to Olaf
804 Flebbe for the patch.
806 Fix DHCP when using --listen-address with an IP address
807 which is not the primary address of an interface.
809 Add --dhcp-client-update option.
811 Add Lua integration. Dnsmasq can now execute a DHCP
812 lease-change script written in Lua. This needs to be
813 enabled at compile time by setting HAVE_LUASCRIPT in
814 src/config.h or running "make COPTS=-DHAVE_LUASCRIPT"
815 Thanks to Jan-Piet Mens for the idea and proof-of-concept
818 Tidied src/config.h to distinguish between
819 platform-dependent compile-time options which are selected
820 automatically, and builder-selectable compile time
821 options. Document the latter better, and describe how to
822 set them from the make command line.
824 Tidied up IPPROTO_IP/SOL_IP (and IPv6 equivalent)
825 confusion. IPPROTO_IP works everywhere now.
827 Set TOS on DHCP sockets, this improves things on busy
828 wireless networks. Thanks to Dave Taht for the patch.
830 Determine VERSION automatically based on git magic:
831 release tags or hash values.
833 Improve start-up speed when reading large hosts files
834 containing many distinct addresses.
836 Fix problem if dnsmasq is started without the stdin,
837 stdout and stderr file descriptors open. This can manifest
838 itself as 100% CPU use. Thanks to Chris Moore for finding
841 Fix shell-scripting bug in bld/pkg-wrapper. Thanks to
842 Mark Mitchell for the patch.
844 Allow the TFP server or boot server in --pxe-service, to
845 be a domain name instead of an IP address. This allows for
846 round-robin to multiple servers, in the same way as
847 --dhcp-boot. A good suggestion from Cristiano Cumer.
849 Support BUILDDIR variable in the Makefile. Allows builds
850 for multiple archs from the same source tree with eg.
851 make BUILDDIR=linux (relative to dnsmasq tree)
852 make BUILDDIR=/tmp/openbsd (absolute path)
853 If BUILDDIR is not set, compilation happens in the src
854 directory, as before. Suggestion from Mark Mitchell.
856 Support DHCPv6. Support is there for the sort of things
857 the existing v4 server does, including tags, options,
858 static addresses and relay support. Missing is prefix
859 delegation, which is probably not required in the dnsmasq
860 niche, and an easy way to accept prefix delegations from
861 an upstream DHCPv6 server, which is. Future plans include
862 support for DHCPv6 router option and MAC address option
863 (to make selecting clients by MAC address work like IPv4).
864 These will be added as the standards mature.
865 This code has been tested, but this is the first release,
866 so don't bet the farm on it just yet. Many thanks to all
867 testers who have got it this far.
869 Support IPv6 router advertisements. This is a
870 simple-minded implementation, aimed at providing the
871 vestigial RA needed to go alongside IPv6. Is picks up
872 configuration from the DHCPv6 conf, and should just need
873 enabling with --enable-ra.
875 Fix long-standing wrinkle with --localise-queries that
876 could result in wrong answers when DNS packets arrive
877 via an interface other than the expected one. Thanks to
878 Lorenzo Milesi and John Hanks for spotting this one.
880 Update French translation. Thanks to Gildas Le Nadan.
882 Update Polish translation. Thanks to Jan Psota.
886 Fix regression in 2.58 which caused failure to start up
887 with some combinations of dnsmasq config and IPv6 kernel
888 network config. Thanks to Brielle Bruns for the bug
891 Improve dnsmasq's behaviour when network interfaces are
892 still doing duplicate address detection (DAD). Previously,
893 dnsmasq would wait up to 20 seconds at start-up for the
894 DAD state to terminate. This is broken for bridge
895 interfaces on recent Linux kernels, which don't start DAD
896 until the bridge comes up, and so can take arbitrary
897 time. The new behaviour lets dnsmasq poll for an arbitrary
898 time whilst providing service on other interfaces. Thanks
899 to Stephen Hemminger for pointing out the problem.
903 Provide a definition of the SA_SIZE macro where it's
904 missing. Fixes build failure on openBSD.
906 Don't include a zero terminator at the end of messages
907 sent to /dev/log when /dev/log is a datagram socket.
908 Thanks to Didier Rabound for spotting the problem.
910 Add --dhcp-sequential-ip flag, to force allocation of IP
911 addresses in ascending order. Note that the default
912 pseudo-random mode is in general better but some
913 server-deployment applications need this.
915 Fix problem where a server-id of 0.0.0.0 is sent to a
916 client when a dhcp-relay is in use if a client renews a
917 lease after dnsmasq restart and before any clients on the
918 subnet get a new lease. Thanks to Mike Ruiz for assistance
919 in chasing this one down.
921 Don't return NXDOMAIN to an AAAA query if we have CNAME
922 which points to an A record only: NODATA is the correct
923 reply in this case. Thanks to Tom Fernandes for spotting
926 Relax the need to supply a netmask in --dhcp-range for
927 networks which use a DHCP relay. Whilst this is still
928 desireable, in the absence of a netmask dnsmasq will use
929 a default based on the class (A, B, or C) of the address.
930 This should at least remove a cause of mysterious failure
931 for people using RFC1918 addresses and relays.
933 Add support for Linux conntrack connection marking. If
934 enabled with --conntrack, the connection mark for incoming
935 DNS queries will be copied to the outgoing connections
936 used to answer those queries. This allows clever firewall
937 and accounting stuff. Only available if dnsmasq is
938 compiled with HAVE_CONNTRACK and adds a dependency on
939 libnetfilter-conntrack. Thanks to Ed Wildgoose for the
940 initial idea, testing and sponsorship of this function.
942 Provide a sane error message when someone attempts to
943 match a tag in --dhcp-host.
945 Tweak the behaviour of --domain-needed, to avoid problems
946 with recursive nameservers downstream of dnsmasq. The new
947 behaviour only stops A and AAAA queries, and returns
948 NODATA rather than NXDOMAIN replies.
950 Efficiency fix for very large DHCP configurations, thanks
951 to James Gartrell and Mike Ruiz for help with this.
953 Allow the TFTP-server address in --dhcp-boot to be a
954 domain-name which is looked up in /etc/hosts. This can
955 give multiple IP addresses which are used round-robin,
956 thus doing TFTP server load-balancing. Thanks to Sushil
957 Agrawal for the patch.
959 When two tagged dhcp-options for a particular option
960 number are both valid, use the one which is valid without
961 a tag from the dhcp-range. Allows overriding of the value
962 of a DHCP option for a particular host as well as
963 per-network values. So
964 --dhcp-range=set:interface1,......
965 --dhcp-host=set:myhost,.....
966 --dhcp-option=tag:interface1,option:nis-domain,"domain1"
967 --dhcp-option=tag:myhost,option:nis-domain,"domain2"
968 will set the NIS-domain to domain1 for hosts in the range, but
969 override that to domain2 for a particular host.
971 Fix bug which resulted in truncated files and timeouts for
972 some TFTP transfers. The bug only occurs with netascii
973 transfers and needs an unfortunate relationship between
974 file size, blocksize and the number of newlines in the
975 last block before it manifests itself. Many thanks to
976 Alkis Georgopoulos for spotting the problem and providing
977 a comprehensive test-case.
979 Fix regression in TFTP server on *BSD platforms introduced
980 in version 2.56, due to confusion with sockaddr
981 length. Many thanks to Loic Pefferkorn for finding this.
983 Support scope-ids in IPv6 addresses of nameservers from
984 /etc/resolv.conf and in --server options. Eg
985 nameserver fe80::202:a412:4512:7bbf%eth0 or
986 server=fe80::202:a412:4512:7bbf%eth0. Thanks to
987 Michael Stapelberg for the suggestion.
989 Update Polish translation, thanks to Jan Psota.
991 Update French translation. Thanks to Gildas Le Nadan.
995 Add patches to allow build under Android.
997 Provide our own header for the DNS protocol, rather than
998 relying on arpa/nameser.h. This has proved more or less
999 defective over the years and the final straw is that it's
1000 effectively empty on Android.
1002 Fix regression in 2.56 which caused hex constants in
1003 configuration to be rejected if they contain the '*'
1006 Correct wrong casts of arguments to ctype.h functions,
1007 isdigit(), isxdigit() etc. Thanks to Matthias Andree for
1010 Allow build with IDN support independently from i18n.
1011 IDN support continues to be included automatically
1012 when i18n is included.
1013 'make COPTS=-DHAVE_IDN' is the magic incantation.
1015 Modify check on extraneous command line junk (added in
1016 2.56) so that it doesn't complain about extra _empty_
1017 arguments. Otherwise this breaks libvirt.
1021 Add a patch to allow dnsmasq to get interface names right in a
1022 Solaris zone. Thanks to Dj Padzensky for this.
1024 Improve data-type parsing heuristics so that
1025 --dhcp-option=option:domain-search,.
1026 treats the value as a string and not an IP address.
1027 Thanks to Clemens Fischer for spotting that.
1029 Add IPv6 support to the TFTP server. Many thanks to Jan
1030 'RedBully' Seiffert for the patches.
1032 Log DNS queries at level LOG_INFO, rather then
1033 LOG_DEBUG. This makes things consistent with DHCP
1034 logging. Thanks to Adam Pribyl for spotting the problem.
1036 Ensure that dnsmasq terminates cleanly when using
1037 --syslog-async even if it cannot make a connection to the
1040 Add --add-mac option. This is to support currently
1041 experimental DNS filtering facilities. Thanks to Benjamin
1042 Petrin for the orignal patch.
1044 Fix bug which meant that tags were ignored in dhcp-range
1045 configuration specifying PXE-proxy service. Thanks to
1046 Cristiano Cumer for spotting this.
1048 Raise an error if there is extra junk, not part of an
1049 option, on the command line.
1051 Flag a couple of log messages in cache.c as coming from
1052 the DHCP subsystem. Thanks to Olaf Westrik for the patch.
1054 Omit timestamps from logs when a) logging to stderr and
1055 b) --keep-in-forground is set. The logging facility on the
1056 other end of stderr can be assumned to supply them. Thanks
1057 to John Hallam for the patch.
1059 Don't complain about strings longer than 255 characters in
1060 --txt-record, just split the long strings into 255
1061 character chunks instead.
1063 Fix crash on double-free. This bug can only happen when
1064 dhcp-script is in use and then only in rare circumstances
1065 triggered by high DHCP transaction rate and a slow
1066 script. Thanks to Ferenc Wagner for finding the problem.
1068 Only log that a file has been sent by TFTP after the
1069 transfer has completed succesfully.
1071 A good suggestion from Ferenc Wagner: extend
1072 the --domain option to allow this sort of thing:
1073 --domain=thekelleys.org.uk,192.168.0.0/24,local
1074 which automatically creates
1075 --local=/thekelleys.org.uk/
1076 --local=/0.168.192.in-addr.arpa/
1078 Tighten up syntax checking of hex contants in the config
1079 file. Thanks to Fred Damen for spotting this.
1081 Add dnsmasq logo/icon, contributed by Justin Swift. Many
1084 Never cache DNS replies which have the 'cd' bit set, or
1085 which result from queries forwarded with the 'cd' bit
1086 set. The 'cd' bit instructs a DNSSEC validating server
1087 upstream to ignore signature failures and return replies
1088 anyway. Without this change it's possible to pollute the
1089 dnsmasq cache with bad data by making a query with the
1090 'cd' bit set and subsequent queries would return this data
1091 without its being marked as suspect. Thanks to Anders
1092 Kaseorg for pointing out this problem.
1094 Add --proxy-dnssec flag, for compliance with RFC
1095 4035. Dnsmasq will now clear the 'ad' bit in answers returned
1096 from upstream validating nameservers unless this option is
1099 Allow a filename of "-" for --conf-file to read
1100 stdin. Suggestion from Timothy Redaelli.
1102 Rotate the order of SRV records in replies, to provide
1103 round-robin load balancing when all the priorities are
1104 equal. Thanks to Peter McKinney for the suggestion.
1107 contrib/MacOSX-launchd/uk.org.thekelleys.dnsmasq.plist
1108 so that it doesn't log all queries to a file by
1109 default. Thanks again to Peter McKinney.
1111 By default, setting an IPv4 address for a domain but not
1112 an IPv6 address causes dnsmasq to return
1113 an NODATA reply for IPv6 (or vice-versa). So
1114 --address=/google.com/1.2.3.4 stops IPv6 queries for
1115 *google.com from being forwarded. Make it possible to
1116 override this behaviour by defining the sematics if the
1117 same domain appears in both --server and --address.
1118 In that case, the --address has priority for the address
1119 family in which is appears, but the --server has priority
1120 of the address family which doesn't appear in --adddress
1122 --address=/google.com/1.2.3.4
1123 --server=/google.com/#
1124 will return 1.2.3.4 for IPv4 queries for *.google.com but
1125 forward IPv6 queries to the normal upstream nameserver.
1126 Similarly when setting an IPv6 address
1127 only this will allow forwarding of IPv4 queries. Thanks to
1128 William for pointing out the need for this.
1130 Allow more than one --dhcp-optsfile and --dhcp-hostsfile
1131 and make them understand directories as arguments in the
1132 same way as --addn-hosts. Suggestion from John Hanks.
1134 Ignore rebinding requests for leases we don't know
1135 about. Rebind is broadcast, so we might get to overhear a
1136 request meant for another DHCP server. NAKing this is
1137 wrong. Thanks to Brad D'Hondt for assistance with this.
1139 Fix cosmetic bug which produced strange output when
1140 dumping cache statistics with some configurations. Thanks
1141 to Fedor Kozhevnikov for spotting this.
1145 Fix crash when /etc/ethers is in use. Thanks to
1146 Gianluigi Tiesi for finding this.
1148 Fix crash in netlink_multicast(). Thanks to Arno Wald for
1151 Allow the empty domain "." in dhcp domain-search (119)
1156 There is no version 2.54 to avoid confusion with 2.53,
1157 which incorrectly identifies itself as 2.54.
1161 Fix failure to compile on Debian/kFreeBSD. Thanks to
1162 Axel Beckert and Petr Salinger.
1164 Fix code to avoid scary strict-aliasing warnings
1165 generated by gcc 4.4.
1167 Added FAQ entry warning about DHCP failures with Vista
1168 when firewalls block 255.255.255.255.
1170 Fixed bug which caused bad things to happen if a
1171 resolv.conf file which exists is subsequently removed.
1172 Thanks to Nikolai Saoukh for the patch.
1174 Rationalised the DHCP tag system. Every configuration item
1175 which can set a tag does so by adding "set:<tag>" and
1176 every configuration item which is conditional on a tag is
1177 made so by "tag:<tag>". The NOT operator changes to '!',
1178 which is a bit more intuitive too. Dhcp-host directives
1179 can set more than one tag now. The old '#' NOT,
1180 "net:" prefix and no-prefixes are still honoured, so
1181 no existing config file needs to be changed, but
1182 the documentation and new-style config files should be
1183 much less confusing.
1185 Added --tag-if to allow boolean operations on tags.
1186 This allows complicated logic to be clearer and more
1187 general. A great suggestion from Richard Voigt.
1189 Add broadcast/unicast information to DHCP logging.
1191 Allow --dhcp-broadcast to be unconditional.
1193 Fixed incorrect behaviour with NOT <tag> conditionals in
1194 dhcp-options. Thanks to Max Turkewitz for assistance
1197 If we send vendor-class encapsulated options based on the
1198 vendor-class supplied by the client, and no explicit
1199 vendor-class option is given, echo back the vendor-class
1202 Fix bug which stopped dnsmasq from matching both a
1203 circuitid and a remoteid. Thanks to Ignacio Bravo for
1206 Add --dhcp-proxy, which makes it possible to configure
1207 dnsmasq to use a DHCP relay agent as a full proxy, with
1208 all DHCP messages passing through the proxy. This is
1209 useful if the relay adds extra information to the packets
1210 it forwards, but cannot be configured with the RFC 5107
1211 server-override option.
1213 Added interface:<iface name> part to dhcp-range. The
1214 semantics of this are very odd at first sight, but it
1215 allows a single line of the form
1216 dhcp-range=interface:virt0,192.168.0.4,192.168.0.200
1217 to be added to dnsmasq configuration which then supplies
1218 DHCP and DNS services to that interface, without affecting
1219 what services are supplied to other interfaces and
1220 irrespective of the existance or lack of
1221 interface=<interface>
1222 lines elsewhere in the dnsmasq configuration. The idea is
1223 that such a line can be added automatically by libvirt
1224 or equivalent systems, without disturbing any manual
1227 Similarly to the above, allow --enable-tftp=<interface>
1229 Allow a TFTP root to be set separately for requests via
1230 different interfaces, --tftp-root=<path>,<interface>
1232 Correctly handle and log clashes between CNAMES and
1233 DNS names being given to DHCP leases. This fixes a bug
1234 which caused nonsense IP addresses to be logged. Thanks to
1235 Sergei Zhirikov for finding and analysing the problem.
1237 Tweak flush_log so as to avoid leaving the log
1238 file in non-blocking mode. O_NONBLOCK is a property of the
1239 file, not the process/descriptor.
1241 Fix contrib/Solaris10/create_package
1242 (/usr/man -> /usr/share/man) Thanks to Vita Batrla.
1244 Fix a problem where, if a client got a lease, then went
1245 to another subnet and got another lease, then moved back,
1246 it couldn't resume the old lease, but would instead get
1247 a new address. Thanks to Leonardo Rodrigues for spotting
1248 this and testing the fix.
1250 Fix weird bug which sometimes omitted certain characters
1251 from the start of quoted strings in dhcp-options. Thanks
1252 to Dayton Turner for spotting the problem.
1254 Add facility to redirect some domains to the standard
1255 upstream servers: this allows something like
1256 --server=/google.com/1.2.3.4 --server=/www.google.com/#
1257 which will send queries for *.google.com to 1.2.3.4,
1258 except *www.google.com which will be forwarded as usual.
1259 Thanks to AJ Weber for prompting this addition.
1261 Improve the hash-algorithm used to generate IP addresses
1262 from MAC addresses during initial DHCP address
1263 allocation. This improves performance when large numbers
1264 of hosts with similar MAC addresses all try and get an IP
1265 address at the same time. Thanks to Paul Smith for his
1268 Tweak DHCP code so that --bridge-interface can be used to
1269 select which IP alias of an interface should be used for
1270 DHCP purposes on Linux. If eth0 has an alias eth0:dhcp
1271 then adding --bridge-interface=eth0:dhcp,eth0 will use
1272 the address of eth0:dhcp to determine the correct subnet
1273 for DHCP address allocation. Thanks to Pawel Golaszewski
1274 for prompting this and Eric Cooper for further testing.
1276 Add --dhcp-generate-names. Suggestion by Ferenc Wagner.
1278 Tweak DNS server selection algorithm when there is more
1279 than one server available for a domain, eg.
1280 --server=/mydomain/1.1.1.1
1281 --server=/mydomain/2.2.2.2
1282 Thanks to Alberto Cuesta-Canada for spotting a weakness
1285 Add --max-ttl. Thanks to Fredrik Ringertz for the patch.
1287 Allow --log-facility=- to force all logging to
1288 stderr. Suggestion from Clemens Fischer.
1290 Fix regression which caused configuration like
1291 --address=/.domain.com/1.2.3.4 to be rejected. The dot to the
1292 left of the domain has been implied and not required for a
1293 long time, but it should be accepted for backward
1294 compatibility. Thanks to Andrew Burcin for spotting this.
1296 Add --rebind-domain-ok and --rebind-localhost-ok.
1297 Suggestion from Clemens Fischer.
1299 Log replies to queries of type TXT, when --log-queries
1302 Fix compiler warnings when compiled with -DNO_DHCP. Thanks
1303 to Shantanu Gadgil for the patch.
1305 Updated French translation. Thanks to Gildas Le Nadan.
1307 Updated Polish translation. Thanks to Jan Psota.
1309 Updated German translation. Thanks to Matthias Andree.
1311 Added contrib/static-arp, thanks to Darren Hoo.
1313 Fix corruption of the domain when a name from /etc/hosts
1314 overrides one supplied by a DHCP client. Thanks to Fedor
1315 Kozhevnikov for spotting the problem.
1317 Updated Spanish translation. Thanks to Chris Chatham.
1321 Work around a Linux kernel bug which insists that the
1322 length of the option passed to setsockopt must be at least
1323 sizeof(int) bytes, even if we're calling SO_BINDTODEVICE
1324 and the device name is "lo". Note that this is fixed
1325 in kernel 2.6.31, but the workaround is harmless and
1326 allows earlier kernels to be used. Also fix dnsmasq
1327 bug which reported the wrong address when this failed.
1328 Thanks to Fedor for finding this.
1330 The API for IPv6 PKTINFO changed around Linux kernel
1331 2.6.14. Workaround the case where dnsmasq is compiled
1332 against newer headers, but then run on an old kernel:
1333 necessary for some *WRT distros.
1335 Re-read the set of network interfaces when re-loading
1336 /etc/resolv.conf if --bind-interfaces is not set. This
1337 handles the case that loopback interfaces do not exist
1338 when dnsmasq is first started.
1340 Tweak the PXE code to support port 4011. This should
1341 reduce broadcasts and make things more reliable when other
1342 servers are around. It also improves inter-operability
1343 with certain clients.
1345 Make a pxe-service configuration with no filename or boot
1346 service type legal: this does a local boot. eg.
1347 pxe-service=x86PC, "Local boot"
1349 Be more conservative in detecting "A for A"
1350 queries. Dnsmasq checks if the name in a type=A query looks
1351 like a dotted-quad IP address and answers the query itself
1352 if so, rather than forwarding it. Previously dnsmasq
1353 relied in the library function inet_addr() to convert
1354 addresses, and that will accept some things which are
1355 confusing in this context, like 1.2.3 or even just
1356 1234. Now we only do A for A processing for four decimal
1357 numbers delimited by dots.
1359 A couple of tweaks to fix compilation on Solaris. Thanks
1360 to Joel Macklow for help with this.
1362 Another Solaris compilation tweak, needed for Solaris
1363 2009.06. Thanks to Lee Essen for that.
1365 Added extract packaging stuff from Lee Essen to
1368 Increased the default limit on number of leases to 1000
1369 (from 150). This is mainly a defence against DoS attacks,
1370 and for the average "one for two class C networks"
1371 installation, IP address exhaustion does that just as
1372 well. Making the limit greater than the number of IP
1373 addresses available in such an installation removes a
1374 surprise which otherwise can catch people out.
1376 Removed extraneous trailing space in the value of the
1377 DNSMASQ_TIME_REMAINING DNSMASQ_LEASE_LENGTH and
1378 DNSMASQ_LEASE_EXPIRES environment variables. Thanks to
1379 Gildas Le Nadan for spotting this.
1381 Provide the network-id tags for a DHCP transaction to
1382 the lease-change script in the environment variable
1383 DNSMASQ_TAGS. A good suggestion from Gildas Le Nadan.
1385 Add support for RFC3925 "Vendor-Identifying Vendor
1386 Options". The syntax looks like this:
1387 --dhcp-option=vi-encap:<enterprise number>, .........
1389 Add support to --dhcp-match to allow matching against
1390 RFC3925 "Vendor-Identifying Vendor Classes". The syntax
1392 --dhcp-match=tag,vi-encap<enterprise number>, <value>
1394 Add some application specific code to assist in
1395 implementing the Broadband forum TR069 CPE-WAN
1396 specification. The details are in contrib/CPE-WAN/README
1398 Increase the default DNS packet size limit to 4096, as
1399 recommended by RFC5625 section 4.4.3. This can be
1400 reconfigured using --edns-packet-max if needed. Thanks to
1401 Francis Dupont for pointing this out.
1403 Rewrite query-ids even for TSIG signed packets, since
1404 this is allowed by RFC5625 section 4.5.
1406 Use getopt_long by default on OS X. It has been supported
1407 since version 10.3.0. Thanks to Arek Dreyer for spotting
1410 Added up-to-date startup configuration for MacOSX/launchd
1411 in contrib/MacOSX-launchd. Thanks to Arek Dreyer for
1414 Fix link error when including Dbus but excluding DHCP.
1415 Thanks to Oschtan for the bug report.
1417 Updated French translation. Thanks to Gildas Le Nadan.
1419 Updated Polish translation. Thanks to Jan Psota.
1421 Updated Spanish translation. Thanks to Chris Chatham.
1423 Fixed confusion about domains, when looking up DHCP hosts
1424 in /etc/hosts. This could cause spurious "Ignoring
1425 domain..." messages. Thanks to Fedor Kozhevnikov for
1426 finding and analysing the problem.
1430 Add support for internationalised DNS. Non-ASCII characters
1431 in domain names found in /etc/hosts, /etc/ethers and
1432 /etc/dnsmasq.conf will be correctly handled by translation to
1433 punycode, as specified in RFC3490. This function is only
1434 available if dnsmasq is compiled with internationalisation
1435 support, and adds a dependency on GNU libidn. Without i18n
1436 support, dnsmasq continues to be compilable with just
1437 standard tools. Thanks to Yves Dorfsman for the
1440 Add two more environment variables for lease-change scripts:
1441 First, DNSMASQ_SUPPLIED_HOSTNAME; this is set to the hostname
1442 supplied by a client, even if the actual hostname used is
1443 over-ridden by dhcp-host or dhcp-ignore-names directives.
1444 Also DNSMASQ_RELAY_ADDRESS which gives the address of
1445 a DHCP relay, if used.
1446 Suggestions from Michael Rack.
1448 Fix regression which broke echo of relay-agent
1449 options. Thanks to Michael Rack for spotting this.
1451 Don't treat option 67 as being interchangeable with
1452 dhcp-boot parameters if it's specified as
1455 Make the code to call scripts on lease-change compile-time
1456 optional. It can be switched off by editing src/config.h
1457 or building with "make COPTS=-DNO_SCRIPT".
1459 Make the TFTP server cope with filenames from Windows/DOS
1460 which use '\' as pathname separator. Thanks to Ralf for
1463 Updated Polish translation. Thanks to Jan Psota.
1465 Warn if an IP address is duplicated in /etc/ethers. Thanks
1466 to Felix Schwarz for pointing this out.
1468 Teach --conf-dir to take an option list of file suffices
1469 which will be ignored when scanning the directory. Useful
1470 for backup files etc. Thanks to Helmut Hullen for the
1473 Add new DHCP option named tftpserver-address, which
1474 corresponds to the third argument of dhcp-boot. This
1475 allows the complete functionality of dhcp-boot to be
1476 replicated with dhcp-option. Useful when using
1479 Test which upstream nameserver to use every 10 seconds
1480 or 50 queries and not just when a query times out and
1481 is retried. This should improve performance when there
1482 is a slow nameserver in the list. Thanks to Joe for the
1485 Don't do any PXE processing, even for clients with the
1486 correct vendorclass, unless at least one pxe-prompt or
1487 pxe-service option is given. This stops dnsmasq
1488 interfering with proxy PXE subsystems when it is just
1489 the DHCP server. Thanks to Spencer Clark for spotting this.
1491 Limit the blocksize used for TFTP transfers to a value
1492 which avoids packet fragmentation, based on the MTU of the
1493 local interface. Many netboot ROMs can't cope with
1496 Honour dhcp-ignore configuration for PXE and proxy-PXE
1497 requests. Thanks to Niels Basjes for the bug report.
1499 Updated French translation. Thanks to Gildas Le Nadan.
1503 Fix security problem which allowed any host permitted to
1504 do TFTP to possibly compromise dnsmasq by remote buffer
1505 overflow when TFTP enabled. Thanks to Core Security
1506 Technologies and Iván Arce, Pablo Hernán Jorge, Alejandro
1507 Pablo Rodriguez, Martín Coco, Alberto Soliño Testa and
1508 Pablo Annetta. This problem has Bugtraq id: 36121
1511 Fix a problem which allowed a malicious TFTP client to
1512 crash dnsmasq. Thanks to Steve Grubb at Red Hat for
1513 spotting this. This problem has Bugtraq id: 36120 and
1518 Fix regression in 2.48 which disables the lease-change
1519 script. Thanks to Jose Luis Duran for spotting this.
1521 Log TFTP "file not found" errors. These were not logged,
1522 since a normal PXELinux boot generates many of them, but
1523 the lack of the messages seems to be more confusing than
1524 routinely seeing them when there is no real error.
1526 Update Spanish translation. Thanks to Chris Chatham.
1530 Archived the extensive, backwards, changelog to
1531 CHANGELOG.archive. The current changelog now runs from
1532 version 2.43 and runs conventionally.
1534 Fixed bug which broke binding of servers to physical
1535 interfaces when interface names were longer than four
1536 characters. Thanks to MURASE Katsunori for the patch.
1538 Fixed netlink code to check that messages come from the
1539 correct source, and not another userspace process. Thanks
1540 to Steve Grubb for the patch.
1542 Maintainability drive: removed bug and missing feature
1543 workarounds for some old platforms. Solaris 9, OpenBSD
1544 older than 4.1, Glibc older than 2.2, Linux 2.2.x and
1545 DBus older than 1.1.x are no longer supported.
1547 Don't read included configuration files more than once:
1548 allows complex configuration structures without problems.
1550 Mark log messages from the various subsystems in dnsmasq:
1551 messages from the DHCP subsystem now have the ident string
1552 "dnsmasq-dhcp" and messages from TFTP have ident
1553 "dnsmasq-tftp". Thanks to Olaf Westrik for the patch.
1555 Fix possible infinite DHCP protocol loop when an IP
1556 address nailed to a hostname (not a MAC address) and a
1557 host sometimes provides the name, sometimes not.
1559 Allow --addn-hosts to take a directory: all the files
1560 in the directory are read. Thanks to Phil Cornelius for
1563 Support --bridge-interface on all platforms, not just BSD.
1565 Added support for advanced PXE functions. It's now
1566 possible to define a prompt and menu options which will
1567 be displayed when a client PXE boots. It's also possible to
1568 hand-off booting to other boot servers. Proxy-DHCP, where
1569 dnsmasq just supplies the PXE information and another DHCP
1570 server does address allocation, is also allowed. See the
1571 --pxe-prompt and --pxe-service keywords. Thanks to
1572 Alkis Georgopoulos for the suggestion and Guilherme Moro
1573 and Michael Brown for assistance.
1575 Improvements to DHCP logging. Thanks to Tom Metro for
1578 Add ability to build dnsmasq without DHCP support. To do
1579 this, edit src/config.h or build with
1580 "make COPTS=-DNO_DHCP". Thanks to Mahavir Jain for the patch.
1582 Added --test command-line switch - syntax check
1583 configuration files only.
1585 Updated French translation. Thanks to Gildas Le Nadan.
1589 Updated French translation. Thanks to Gildas Le Nadan.
1591 Fixed interface enumeration code to work on NetBSD
1592 5.0. Thanks to Roy Marples for the patch.
1594 Updated config.h to use the same location for the lease
1595 file on NetBSD as the other *BSD variants. Also allow
1596 LEASEFILE and CONFFILE symbols to be overriden in CFLAGS.
1598 Handle duplicate address detection on IPv6 more
1599 intelligently. In IPv6, an interface can have an address
1600 which is not usable, because it is still undergoing DAD
1601 (such addresses are marked "tentative"). Attempting to
1602 bind to an address in this state returns an error,
1603 EADDRNOTAVAIL. Previously, on getting such an error,
1604 dnsmasq would silently abandon the address, and never
1605 listen on it. Now, it retries once per second for 20
1606 seconds before generating a fatal error. 20 seconds should
1607 be long enough for any DAD process to complete, but can be
1608 adjusted in src/config.h if necessary. Thanks to Martin
1609 Krafft for the bug report.
1611 Add DBus introspection. Patch from Jeremy Laine.
1613 Update Dbus configuration file. Patch from Colin Walters.
1615 http://bugs.freedesktop.org/show_bug.cgi?id=18961
1617 Support arbitrarily encapsulated DHCP options, suggestion
1618 and initial patch from Samium Gromoff. This is useful for
1619 (eg) gPXE, which expect all its private options to be
1620 encapsulated inside a single option 175. So, eg,
1622 dhcp-option = encap:175, 190, "iscsi-client0"
1623 dhcp-option = encap:175, 191, "iscsi-client0-secret"
1625 will provide iSCSI parameters to gPXE.
1627 Enhance --dhcp-match to allow testing of the contents of a
1628 client-sent option, as well as its presence. This
1629 application in mind for this is RFC 4578
1630 client-architecture specifiers, but it's generally useful.
1631 Joey Korkames suggested the enhancement.
1633 Move from using the IP_XMIT_IF ioctl to IP_BOUND_IF on
1634 OpenSolaris. Thanks to Bastian Machek for the heads-up.
1636 No longer complain about blank lines in
1637 /etc/ethers. Thanks to Jon Nelson for the patch.
1639 Fix binding of servers to physical devices, eg
1640 --server=/domain/1.2.3.4@eth0 which was broken from 2.43
1641 onwards unless --query-port=0 set. Thanks to Peter Naulls
1644 Reply to DHCPINFORM requests even when the supplied ciaddr
1645 doesn't fall in any dhcp-range. In this case it's not
1646 possible to supply a complete configuration, but
1647 individually-configured options (eg PAC) may be useful.
1649 Allow the source address of an alias to be a range:
1650 --alias=192.168.0.0,10.0.0.0,255.255.255.0 maps the whole
1651 subnet 192.168.0.0->192.168.0.255 to 10.0.0.0->10.0.0.255,
1653 --alias=192.168.0.10-192.168.0.40,10.0.0.0,255.255.255.0
1654 maps only the 192.168.0.10->192.168.0.40 region. Thanks to
1655 Ib Uhrskov for the suggestion.
1657 Don't dynamically allocate DHCP addresses which may break
1658 Windows. Addresses which end in .255 or .0 are broken in
1659 Windows even when using supernetting.
1660 --dhcp-range=192.168.0.1,192.168.1.254,255,255,254.0 means
1661 192.168.0.255 is a valid IP address, but not for Windows.
1662 See Microsoft KB281579. We therefore no longer allocate
1663 these addresses to avoid hard-to-diagnose problems.
1665 Update Polish translation. Thanks to Jan Psota.
1667 Delete the PID-file when dnsmasq shuts down. Note that by
1668 this time, dnsmasq is normally not running as root, so
1669 this will fail if the PID-file is stored in a root-owned
1670 directory; such failure is silently ignored. To take
1671 advantage of this feature, the PID-file must be stored in a
1672 directory owned and write-able by the user running
1677 Allow --bootp-dynamic to take a netid tag, so that it may
1678 be selectively enabled. Thanks to Olaf Westrik for the
1681 Remove ISC-leasefile reading code. This has been
1682 deprecated for a long time, and last time I removed it, it
1683 ended up going back by request of one user. This time,
1684 it's gone for good; otherwise it would need to be
1685 re-worked to support multiple domains (see below).
1687 Support DHCP clients in multiple DNS domains. This is a
1688 long-standing request. Clients are assigned to a domain
1689 based in their IP address.
1691 Add --dhcp-fqdn flag, which changes behaviour if DNS names
1692 assigned to DHCP clients. When this is set, there must be
1693 a domain associated with each client, and only
1694 fully-qualified domain names are added to the DNS. The
1695 advantage is that the only the FQDN needs to be unique,
1696 so that two or more DHCP clients can share a hostname, as
1697 long as they are in different domains.
1699 Set environment variable DNSMASQ_DOMAIN when invoking
1700 lease-change script. This may be useful information to
1701 have now that it's variable.
1703 Tighten up data-checking code for DNS packet
1704 handling. Thanks to Steve Dodd who found certain illegal
1705 packets which could crash dnsmasq. No memory overwrite was
1706 possible, so this is not a security issue beyond the DoS
1709 Update example config dhcp option 47, the previous
1710 suggestion generated an illegal, zero-length,
1711 option. Thanks to Matthias Andree for finding this.
1713 Rewrite hosts-file reading code to remove the limit of
1714 1024 characters per line. John C Meuser found this.
1716 Create a net-id tag with the name of the interface on
1717 which the DHCP request was received.
1719 Fixed minor memory leak in DBus code, thanks to Jeremy
1720 Laine for the patch.
1722 Emit DBus signals as the DHCP lease database
1723 changes. Thanks to Jeremy Laine for the patch.
1725 Allow for more that one MAC address in a dhcp-host
1726 line. This configuration tells dnsmasq that it's OK to
1727 abandon a DHCP lease of the fixed address to one MAC
1728 address, if another MAC address in the dhcp-host statement
1729 asks for an address. This is useful to give a fixed
1730 address to a host which has two network interfaces
1731 (say, a laptop with wired and wireless interfaces.)
1732 It's very important to ensure that only one interface
1733 at a time is up, since dnsmasq abandons the first lease
1734 and re-uses the address before the leased time has
1735 elapsed. John Gray suggested this.
1737 Tweak the response to a DHCP request packet with a wrong
1738 server-id when --dhcp-authoritative is set; dnsmasq now
1739 returns a DHCPNAK, rather than silently ignoring the
1740 packet. Thanks to Chris Marget for spotting this
1743 Add --cname option. This provides a limited alias
1744 function, usable for DHCP names. Thanks to AJ Weber for
1745 suggestions on this.
1747 Updated contrib/webmin with latest version from Neil
1750 Updated Polish translation. Thanks to Jan Psota.
1752 Correct the text names for DHCP options 64 and 65 to be
1753 "nis+-domain" and "nis+-servers".
1755 Updated Spanish translation. Thanks to Chris Chatham.
1757 Force re-reading of /etc/resolv.conf when an "interface
1762 Fix total DNS failure in release 2.44 unless --min-port
1763 specified. Thanks to Steven Barth and Grant Coady for
1764 bugreport. Also reject out-of-range port spec, which could
1765 break things too: suggestion from Gilles Espinasse.
1769 Fix crash when unknown client attempts to renew a DHCP
1770 lease, problem introduced in version 2.43. Thanks to
1771 Carlos Carvalho for help chasing this down.
1773 Fix potential crash when a host which doesn't have a lease
1774 does DHCPINFORM. Again introduced in 2.43. This bug has
1775 never been reported in the wild.
1777 Fix crash in netlink code introduced in 2.43. Thanks to
1778 Jean Wolter for finding this.
1780 Change implementation of min_port to work even if min-port
1783 Patch to enable compilation of latest Mac OS X. Thanks to
1786 Update Spanish translation. Thanks to Christopher Chatham.
1790 Updated Polish translation. Thanks to Jan Psota.
1792 Flag errors when configuration options are repeated
1795 Further tweaks for GNU/kFreeBSD
1797 Add --no-wrap to msgmerge call - provides nicer .po file
1800 Honour lease-time spec in dhcp-host lines even for
1801 BOOTP. The user is assumed to known what they are doing in
1802 this case. (Hosts without the time spec still get infinite
1803 leases for BOOTP, over-riding the default in the
1804 dhcp-range.) Thanks to Peter Katzmann for uncovering this.
1806 Fix problem matching relay-agent ids. Thanks to Michael
1807 Rack for the bug report.
1809 Add --naptr-record option. Suggestion from Johan
1812 Implement RFC 5107 server-id-override DHCP relay agent
1815 Apply patches from Stefan Kruger for compilation on
1816 Solaris 10 under Sun studio.
1818 Yet more tweaking of Linux capability code, to suppress
1819 pointless wingeing from kernel 2.6.25 and above.
1821 Improve error checking during startup. Previously, some
1822 errors which occurred during startup would be worked
1823 around, with dnsmasq still starting up. Some were logged,
1824 some silent. Now, they all cause a fatal error and dnsmasq
1825 terminates with a non-zero exit code. The errors are those
1826 associated with changing uid and gid, setting process
1827 capabilities and writing the pidfile. Thanks to Uwe
1828 Gansert and the Suse security team for pointing out
1829 this improvement, and Bill Reimers for good implementation
1832 Provide NO_LARGEFILE compile option to switch off largefile
1833 support when compiling against versions of uclibc which
1834 don't support it. Thanks to Stephane Billiart for the patch.
1836 Implement random source ports for interactions with
1837 upstream nameservers. New spoofing attacks have been found
1838 against nameservers which do not do this, though it is not
1839 clear if dnsmasq is vulnerable, since to doesn't implement
1840 recursion. By default dnsmasq will now use a different
1841 source port (and socket) for each query it sends
1842 upstream. This behaviour can suppressed using the
1843 --query-port option, and the old default behaviour
1844 restored using --query-port=0. Explicit source-port
1845 specifications in --server configs are still honoured.
1847 Replace the random number generator, for better
1848 security. On most BSD systems, dnsmasq uses the
1849 arc4random() RNG, which is secure, but on other platforms,
1850 it relied on the C-library RNG, which may be
1851 guessable and therefore allow spoofing. This release
1852 replaces the libc RNG with the SURF RNG, from Daniel
1853 J. Berstein's DJBDNS package.
1855 Don't attempt to change user or group or set capabilities
1856 if dnsmasq is run as a non-root user. Without this, the
1857 change from soft to hard errors when these fail causes
1858 problems for non-root daemons listening on high
1859 ports. Thanks to Patrick McLean for spotting this.
1861 Updated French translation. Thanks to Gildas Le Nadan.
1865 The changelog for version 2.42 and earlier is
1866 available in CHANGELOG.archive.
