1 version 2.69
2 Implement dynamic interface discovery on *BSD. This allows
3 the contructor: syntax to be used in dhcp-range for DHCPv6
4 on the BSD platform. Thanks to Matthias Andree for
5 valuable research on how to implement this.
7 Fix infinite loop associated with some --bogus-nxdomain
8 configs. Thanks fogobogo for the bug report.
10 Fix missing RA RDNS option with configuration like
11 --dhcp-option=option6:23,[::] Thanks to Tsachi Kimeldorfer
12 for spotting the problem.
14 Add [fd00::] and [fe80::] as special addresses in DHCPv6
15 options, analogous to [::]. [fd00::] is replaced with the
16 actual ULA of the interface on the machine running
17 dnsmasq, [fe80::] with the link-local address.
18 Thanks to Tsachi Kimeldorfer for championing this.
20 DNSSEC validation and caching. Dnsmasq needs to be
21 compiled with this enabled, with
23 make dnsmasq COPTS=-DHAVE_DNSSEC
25 this add dependencies on the nettle crypto library and the
26 gmp maths library. It's possible to have these linked
27 statically with
29 make dnsmasq COPTS='-DHAVE_DNSSEC -DHAVE_DNSSEC_STATIC'
31 which bloats the dnsmasq binary to over a megabyte, but
32 saves the size of the shared libraries which are five
33 times that size.
34 To enable, DNSSEC, you will need a set of
35 trust-anchors. Now that the TLDs are signed, this can be
36 the keys for the root zone, and for convenience they are
37 included in trust-anchors.conf in the dnsmasq
38 distribution. You should of course check that these are
39 legitimate and up-to-date. So, adding
41 conf-file=/path/to/trust-anchors.conf
42 dnssec
44 to your config is all thats needed to get things
45 working. The upstream nameservers have to be DNSSEC-capable
46 too, of course. Many ISP nameservers aren't, but the
47 Google public nameservers (8.8.8.8 and 8.8.4.4) are.
48 When DNSSEC is configured, dnsmasq validates any queries
49 for domains which are signed. Query results which are
50 bogus are replaced with SERVFAIL replies, and results
51 which are correctly signed have the AD bit set. In
52 addition, and just as importantly, dnsmasq supplies
53 correct DNSSEC information to clients which are doing
54 their own validation, and caches DNSKEY, DS and RRSIG
55 records, which significantly improve the performance of
56 downstream validators. Setting --log-queries will show
57 DNSSEC in action.
59 The development of DNSSEC in dnsmasq was started by
60 Giovanni Bajo, to whom huge thanks are owed. It has been
61 supported by Comcast, whose techfund grant has allowed for
62 an invaluable period of full-time work to get it to
63 a workable state.
66 version 2.68
67 Use random addresses for DHCPv6 temporary address
68 allocations, instead of algorithmically determined stable
69 addresses.
71 Fix bug which meant that the DHCPv6 DUID was not available
72 in DHCP script runs during the lifetime of the dnsmasq
73 process which created the DUID de-novo. Once the DUID was
74 created and stored in the lease file and dnsmasq
75 restarted, this bug disappeared.
77 Fix bug introduced in 2.67 which could result in erroneous
78 NXDOMAIN returns to CNAME queries.
80 Fix build failures on MacOS X and openBSD.
82 Allow subnet specifications in --auth-zone to be interface
83 names as well as address literals. This makes it possible
84 to configure authoritative DNS when local address ranges
85 are dynamic and works much better than the previous
86 work-around which exempted contructed DHCP ranges from the
87 IP address filtering. As a consequence, that work-around
88 is removed. Under certain circumstances, this change wil
89 break existing configuration: if you're relying on the
90 contructed-range exception, you need to change --auth-zone
91 to specify the same interface as is used to construct your
92 DHCP ranges, probably with a trailing "/6" like this:
93 --auth-zone=example.com,eth0/6 to limit the addresses to
94 IPv6 addresses of eth0.
96 Fix problems when advertising deleted IPv6 prefixes. If
97 the prefix is deleted (rather than replaced), it doesn't
98 get advertised with zero preferred time. Thanks to Tsachi
99 for the bug report.
101 Fix segfault with some locally configured CNAMEs. Thanks
102 to Andrew Childs for spotting the problem.
104 Fix memory leak on re-reading /etc/hosts and friends,
105 introduced in 2.67.
107 Check the arrival interface of incoming DNS and TFTP
108 requests via IPv6, even in --bind-interfaces mode. This
109 isn't possible for IPv4 and can generate scary warnings,
110 but as it's always possible for IPv6 (the API always
111 exists) then we should do it always.
113 Tweak the rules on prefix-lengths in --dhcp-range for
114 IPv6. The new rule is that the specified prefix length
115 must be larger than or equal to the prefix length of the
116 corresponding address on the local interface.
119 version 2.67
120 Fix crash if upstream server returns SERVFAIL when
121 --conntrack in use. Thanks to Giacomo Tazzari for finding
122 this and supplying the patch.
124 Repair regression in 2.64. That release stopped sending
125 lease-time information in the reply to DHCPINFORM
126 requests, on the correct grounds that it was a standards
127 violation. However, this broke the dnsmasq-specific
128 dhcp_lease_time utility. Now, DHCPINFORM returns
129 lease-time only if it's specifically requested
130 (maintaining standards) and the dhcp_lease_time utility
131 has been taught to ask for it (restoring functionality).
133 Fix --dhcp-match, --dhcp-vendorclass and --dhcp-userclass
134 to work with BOOTP and well as DHCP. Thanks to Peter
135 Korsgaard for spotting the problem.
137 Add --synth-domain. Thanks to Vishvananda Ishaya for
138 suggesting this.
140 Fix failure to compile ipset.c if old kernel headers are
141 in use. Thanks to Eugene Rudoy for pointing this out.
143 Handle IPv4 interface-address labels in Linux. These are
144 often used to emulate the old IP-alias addresses. Before,
145 using --interface=eth0 would service all the addresses of
146 eth0, including ones configured as aliases, which appear
147 in ifconfig as eth0:0. Now, only addresses with the label
148 eth0 are active. This is not backwards compatible: if you
149 want to continue to bind the aliases too, you need to add
150 eg. --interface=eth0:0 to the config.
152 Fix "failed to set SO_BINDTODEVICE on DHCP socket: Socket
153 operation on non-socket" error on startup with
154 configurations which have exactly one --interface option
155 and do RA but _not_ DHCPv6. Thanks to Trever Adams for the
156 bug report.
158 Generalise --interface-name to cope with IPv6 addresses
159 and multiple addresses per interface per address family.
161 Fix option parsing for --dhcp-host, which was generating a
162 spurious error when all seven possible items were
163 included. Thanks to Zhiqiang Wang for the bug report.
165 Remove restriction on prefix-length in --auth-zone. Thanks
166 to Toke Hoiland-Jorgensen for suggesting this.
168 Log when the maximum number of concurrent DNS queries is
169 reached. Thanks to Marcelo Salhab Brogliato for the patch.
171 If wildcards are used in --interface, don't assume that
172 there will only ever be one available interface for DHCP
173 just because there is one at start-up. More may appear, so
174 we can't use SO_BINDTODEVICE. Thanks to Natrio for the bug
175 report.
177 Increase timeout/number of retries in TFTP to accomodate
178 AudioCodes Voice Gateways doing streaming writes to flash.
179 Thanks to Damian Kaczkowski for spotting the problem.
181 Fix crash with empty DHCP string options when adding zero
182 terminator. Thanks to Patrick McLean for the bug report.
184 Allow hostnames to start with a number, as allowed in
185 RFC-1123. Thanks to Kyle Mestery for the patch.
187 Fixes to DHCP FQDN option handling: don't terminate FQDN
188 if domain not known and allow a FQDN option with blank
189 name to request that a FQDN option is returned in the
190 reply. Thanks to Roy Marples for the patch.
192 Make --clear-on-reload apply to setting upstream servers
193 via DBus too.
195 When the address which triggered the construction of an
196 advertised IPv6 prefix disappears, continue to advertise
197 the prefix for up to 2 hours, with the preferred lifetime
198 set to zero. This satisfies RFC 6204 4.3 L-13 and makes
199 things work better if a prefix disappears without being
200 deprecated first. Thanks to Uwe Schindler for persuasively
201 arguing for this.
203 Fix MAC address enumeration on *BSD. Thanks to Brad Smith
204 for the bug report.
206 Support RFC-4242 information-refresh-time options in the
207 reply to DHCPv6 information-request. The lease time of the
208 smallest valid dhcp-range is sent. Thanks to Uwe Schindler
209 for suggesting this.
211 Make --listen-address higher priority than --except-interface
212 in all circumstances. Thanks to Thomas Hood for the bugreport.
214 Provide independent control over which interfaces get TFTP
215 service. If enable-tftp is given a list of interfaces, then TFTP
216 is provided on those. Without the list, the previous behaviour
217 (provide TFTP to the same interfaces we provide DHCP to)
218 is retained. Thanks to Lonnie Abelbeck for the suggestion.
220 Add --dhcp-relay config option. Many thanks to vtsl.net
221 for sponsoring this development.
223 Fix crash with empty tag: in --dhcp-range. Thanks to
224 Kaspar Schleiser for the bug report.
226 Add "baseline" and "bloatcheck" makefile targets, for
227 revealing size changes during development. Thanks to
228 Vladislav Grishenko for the patch.
230 Cope with DHCPv6 clients which send REQUESTs without
231 address options - treat them as SOLICIT with rapid commit.
233 Support identification of clients by MAC address in
234 DHCPv6. When using a relay, the relay must support RFC
235 6939 for this to work. It always works for directly
236 connected clients. Thanks to Vladislav Grishenko
237 for prompting this feature.
239 Remove the rule for constructed DHCP ranges that the local
240 address must be either the first or last address in the
241 range. This was originally to avoid SLAAC addresses, but
242 we now explicitly autoconfig and privacy addresses instead.
244 Update Polish translation. Thanks to Jan Psota.
246 Fix problem in DHCPv6 vendorclass/userclass matching
247 code. Thanks to Tanguy Bouzeloc for the patch.
249 Update Spanish transalation. Thanks to Vicente Soriano.
251 Add --ra-param option. Thanks to Vladislav Grishenko for
252 inspiration on this.
254 Add --add-subnet configuration, to tell upstream DNS
255 servers where the original client is. Thanks to DNSthingy
256 for sponsoring this feature.
258 Add --quiet-dhcp, --quiet-dhcp6 and --quiet-ra. Thanks to
259 Kevin Darbyshire-Bryant for the initial patch.
261 Allow A/AAAA records created by --interface-name to be the
262 target of --cname. Thanks to Hadmut Danisch for the
263 suggestion.
265 Avoid treating a --dhcp-host which has an IPv6 address
266 as eligable for use with DHCPv4 on the grounds that it has
267 no address, and vice-versa. Thanks to Yury Konovalov for
268 spotting the problem.
270 Do a better job caching dangling CNAMEs. Thanks to Yves
271 Dorfsman for spotting the problem.
274 version 2.66
275 Add the ability to act as an authoritative DNS
276 server. Dnsmasq can now answer queries from the wider 'net
277 with local data, as long as the correct NS records are set
278 up. Only local data is provided, to avoid creating an open
279 DNS relay. Zone transfer is supported, to allow secondary
280 servers to be configured.
282 Add "constructed DHCP ranges" for DHCPv6. This is intended
283 for IPv6 routers which get prefixes dynamically via prefix
284 delegation. With suitable configuration, stateful DHCPv6
285 and RA can happen automatically as prefixes are delegated
286 and then deprecated, without having to re-write the
287 dnsmasq configuration file or restart the daemon. Thanks to
288 Steven Barth for extensive testing and development work on
289 this idea.
291 Fix crash on startup on Solaris 11. Regression probably
292 introduced in 2.61. Thanks to Geoff Johnstone for the
293 patch.
295 Add code to make behaviour for TCP DNS requests that same
296 as for UDP requests, when a request arrives for an allowed
297 address, but via a banned interface. This change is only
298 active on Linux, since the relevant API is missing (AFAIK)
299 on other platforms. Many thanks to Tomas Hozza for
300 spotting the problem, and doing invaluable discovery of
301 the obscure and undocumented API required for the solution.
303 Don't send the default DHCP option advertising dnsmasq as
304 the local DNS server if dnsmasq is configured to not act
305 as DNS server, or it's configured to a non-standard port.
307 Add DNSMASQ_CIRCUIT_ID, DNSMASQ_SUBCRIBER_ID,
308 DNSMASQ_REMOTE_ID variables to the environment of the
309 lease-change script (and the corresponding Lua). These hold
310 information inserted into the DHCP request by a DHCP relay
311 agent. Thanks to Lakefield Communications for providing a
312 bounty for this addition.
314 Fixed crash, introduced in 2.64, whilst handling DHCPv6
315 information-requests with some common configurations.
316 Thanks to Robert M. Albrecht for the bug report and
317 chasing the problem.
319 Add --ipset option. Thanks to Jason A. Donenfeld for the
320 patch.
322 Don't erroneously reject some option names in --dhcp-match
323 options. Thanks to Benedikt Hochstrasser for the bug report.
325 Allow a trailing '*' wildcard in all interface-name
326 configurations. Thanks to Christian Parpart for the patch.
328 Handle the situation where libc headers define
329 SO_REUSEPORT, but the kernel in use doesn't, to cope with
330 the introduction of this option to Linux. Thanks to Rich
331 Felker for the bug report.
333 Update Polish translation. Thanks to Jan Psota.
335 Fix crash if the configured DHCP lease limit is
336 reached. Regression occurred in 2.61. Thanks to Tsachi for
337 the bug report.
339 Update the French translation. Thanks to Gildas le Nadan.
342 version 2.65
343 Fix regression which broke forwarding of queries sent via
344 TCP which are not for A and AAAA and which were directed to
345 non-default servers. Thanks to Niax for the bug report.
347 Fix failure to build with DHCP support excluded. Thanks to
348 Gustavo Zacarias for the patch.
350 Fix nasty regression in 2.64 which completely broke cacheing.
353 version 2.64
354 Handle DHCP FQDN options with all flag bits zero and
355 --dhcp-client-update set. Thanks to Bernd Krumbroeck for
356 spotting the problem.
358 Finesse the check for /etc/hosts names which conflict with
359 DHCP names. Previously a name/address pair in /etc/hosts
360 which didn't match the name/address of a DHCP lease would
361 generate a warning. Now that only happesn if there is not
362 also a match. This allows multiple addresses for a name in
363 /etc/hosts with one of them assigned via DHCP.
365 Fix broken vendor-option processing for BOOTP. Thanks to
366 Hans-Joachim Baader for the bug report.
368 Don't report spurious netlink errors, regression in
369 2.63. Thanks to Vladislav Grishenko for the patch.
371 Flag DHCP or DHCPv6 in starup logging. Thanks to
372 Vladislav Grishenko for the patch.
374 Add SetServersEx method in DBus interface. Thanks to Dan
375 Williams for the patch.
377 Add SetDomainServers method in DBus interface. Thanks to
378 Roy Marples for the patch.
380 Fix build with later Lua libraries. Thansk to Cristian
381 Rodriguez for the patch.
383 Add --max-cache-ttl option. Thanks to Dennis Kaarsemaker
384 for the patch.
386 Fix breakage of --host-record parsing, resulting in
387 infinte loop at startup. Regression in 2.63. Thanks to
388 Haim Gelfenbeyn for spotting this.
390 Set SO_REUSEADDRESS and SO_V6ONLY options on the DHCPv6
391 socket, this allows multiple instances of dnsmasq on a
392 single machine, in the same way as for DHCPv4. Thanks to
393 Gene Czarcinski and Vladislav Grishenko for work on this.
395 Fix DHCPv6 to do access control correctly when it's
396 configured with --listen-address. Thanks to
397 Gene Czarcinski for sorting this out.
399 Add a "wildcard" dhcp-range which works for any IPv6
400 subnet, --dhcp-range=::,static Useful for Stateless
401 DHCPv6. Thanks to Vladislav Grishenko for the patch.
403 Don't include lease-time in DHCPACK replies to DHCPINFORM
404 queries, since RFC-2131 says we shouldn't. Thanks to
405 Wouter Ibens for pointing this out.
407 Makefile tweak to do dependency checking on header files.
408 Thanks to Johan Peeters for the patch.
410 Check interface for outgoing unsolicited router
411 advertisements, rather than relying on interface address
412 configuration. Thanks to Gene Czarinski for the patch.
414 Handle better attempts to transmit on interfaces which are
415 still doing DAD, and specifically do not just transmit
416 without setting source address and interface, since this
417 can cause very puzzling effects when a router
418 advertisement goes astray. Thanks again to Gene Czarinski.
420 Get RA timers right when there is more than one
421 dhcp-range on a subnet.
424 version 2.63
425 Do duplicate dhcp-host address check in --test mode.
427 Check that tftp-root directories are accessible before
428 start-up. Thanks to Daniel Veillard for the initial patch.
430 Allow more than one --tfp-root flag. The per-interface
431 stuff is pointless without that.
433 Add --bind-dynamic. A hybrid mode between the default and
434 --bind-interfaces which copes with dynamically created
435 interfaces.
437 A couple of fixes to the build system for Android. Thanks
438 to Metin Kaya for the patches.
440 Remove the interface:<interface> argument in --dhcp-range, and
441 the interface argument to --enable-tftp. These were a
442 still-born attempt to allow automatic isolated
443 configuration by libvirt, but have never (to my knowledge)
444 been used, had very strange semantics, and have been
445 superceded by other mechanisms.
447 Fixed bug logging filenames when duplicate dhcp-host
448 addresses are found. Thanks to John Hanks for the patch.
450 Fix regression in 2.61 which broke caching of CNAME
451 chains. Thanks to Atul Gupta for the bug report.
453 Allow the target of a --cname flag to be another --cname.
455 Teach DHCPv6 about the RFC 4242 information-refresh-time
456 option, and add parsing if the minutes, hours and days
457 format for options. Thanks to Francois-Xavier Le Bail for
458 the suggestion.
460 Allow "w" (for week) as multiplier in lease times, as well
461 as seconds, minutes, hours and days. Álvaro Gámez Machado
462 spotted the ommission.
464 Update French translation. Thanks to Gildas Le Nadan.
466 Allow a DBus service name to be given with --enable-dbus
467 which overrides the default,
468 uk.org.thekelleys.dnsmasq. Thanks to Mathieu
469 Trudel-Lapierre for the patch.
471 Set the "prefix on-link" bit in Router
472 Advertisements. Thanks to Gui Iribarren for the patch.
475 version 2.62
476 Update German translation. Thanks to Conrad Kostecki.
478 Cope with router-solict packets wich don't have a valid
479 source address. Thanks to Vladislav Grishenko for the patch.
481 Fixed bug which caused missing periodic router
482 advertisements with some configurations. Thanks to
483 Vladislav Grishenko for the patch.
485 Fixed bug which broke DHCPv6/RA with prefix lengths
486 which are not divisible by 8. Thanks to Andre Coetzee
487 for spotting this.
489 Fix non-response to router-solicitations when
490 router-advertisement configured, but DHCPv6 not
491 configured. Thanks to Marien Zwart for the patch.
493 Add --dns-rr, to allow arbitrary DNS resource records.
495 Fixed bug which broke RA scheduling when an interface had
496 two addresses in the same network. Thanks to Jim Bos for
497 his help nailing this.
499 version 2.61
500 Re-write interface discovery code on *BSD to use
501 getifaddrs. This is more portable, more straightforward,
502 and allows us to find the prefix length for IPv6
503 addresses.
505 Add ra-names, ra-stateless and slaac keywords for DHCPv6.
506 Dnsmasq can now synthesise AAAA records for dual-stack
507 hosts which get IPv6 addresses via SLAAC. It is also now
508 possible to use SLAAC and stateless DHCPv6, and to
509 tell clients to use SLAAC addresses as well as DHCP ones.
510 Thanks to Dave Taht for help with this.
512 Add --dhcp-duid to allow DUID-EN uids to be used.
514 Explicity send DHCPv6 replies to the correct port, instead
515 of relying on clients to send requests with the correct
516 source address, since at least one client in the wild gets
517 this wrong. Thanks to Conrad Kostecki for help tracking
518 this down.
520 Send a preference value of 255 in DHCPv6 replies when
521 --dhcp-authoritative is in effect. This tells clients not
522 to wait around for other DHCP servers.
524 Better logging of DHCPv6 options.
526 Add --host-record. Thanks to Rob Zwissler for the
527 suggestion.
529 Invoke the DHCP script with action "tftp" when a TFTP file
530 transfer completes. The size of the file, address to which
531 it was sent and complete pathname are supplied. Note that
532 version 2.60 introduced some script incompatibilties
533 associated with DHCPv6, and this is a further change. To
534 be safe, scripts should ignore unknown actions, and if
535 not IPv6-aware, should exit if the environment
536 variable DNSMASQ_IAID is set. The use-case for this is
537 to track netboot/install. Suggestion from Shantanu
538 Gadgil.
540 Update contrib/port-forward/dnsmasq-portforward to reflect
541 the above.
543 Set the environment variable DNSMASQ_LOG_DHCP when running
544 the script id --log-dhcp is in effect, so that script can
545 taylor their logging verbosity. Suggestion from Malte
546 Forkel.
548 Arrange that addresses specified with --listen-address
549 work even if there is no interface carrying the
550 address. This is chiefly useful for IPv4 loopback
551 addresses, where any address in 127.0.0.0/8 is a valid
552 loopback address, but normally only 127.0.0.1 appears on
553 the lo interface. Thanks to Mathieu Trudel-Lapierre for
554 the idea and initial patch.
556 Fix crash, introduced in 2.60, when a DHCPINFORM is
557 received from a network which has no valid dhcp-range.
558 Thanks to Stephane Glondu for the bug report.
560 Add a new DHCP lease time keyword, "deprecated" for
561 --dhcp-range. This is only valid for IPv6, and sets the
562 preffered lease time for both DHCP and RA to zero. The
563 effect is that clients can continue to use the address
564 for existing connections, but new connections will use
565 other addresses, if they exist. This makes hitless
566 renumbering at least possible.
568 Fix bug in address6_available() which caused DHCPv6 lease
569 aquisition to fail if more than one dhcp-range in use.
571 Provide RDNSS and DNSSL data in router advertisements,
572 using the settings provided for DHCP options
573 option6:domain-search and option6:dns-server.
575 Tweak logo/favicon.ico to add some transparency. Thanks to
576 SamLT for work on this.
578 Don't cache data from non-recursive nameservers, since it
579 may erroneously look like a valid CNAME to a non-exitant
580 name. Thanks to Ben Winslow for finding this.
582 Call SO_BINDTODEVICE on the DHCP socket(s) when doing DHCP
583 on exactly one interface and --bind-interfaces is set. This
584 makes the OpenStack use-case of one dnsmasq per virtual
585 interface work. This is only available on Linux; it's not
586 supported on other platforms. Thanks to Vishvananda Ishaya
587 and the OpenStack team for the suggestion.
589 Updated French translation. Thanks to Gildas Le Nadan.
591 Give correct from-cache answers to explict CNAME queries.
592 Thanks to Rob Zwissler for spotting this.
594 Add --tftp-lowercase option. Thanks to Oliver Rath for the
595 patch.
597 Ensure that the DBus DhcpLeaseUpdated events are generated
598 when a lease goes through INIT_REBOOT state, even if the
599 dhcp-script is not in use. Thanks to Antoaneta-Ecaterina
600 Ene for the patch.
602 Fix failure of TFTP over IPv4 on OpenBSD platform. Thanks
603 to Brad Smith for spotting this.
606 version 2.60
607 Fix compilation problem in Mac OS X Lion. Thanks to Olaf
608 Flebbe for the patch.
610 Fix DHCP when using --listen-address with an IP address
611 which is not the primary address of an interface.
613 Add --dhcp-client-update option.
615 Add Lua integration. Dnsmasq can now execute a DHCP
616 lease-change script written in Lua. This needs to be
617 enabled at compile time by setting HAVE_LUASCRIPT in
618 src/config.h or running "make COPTS=-DHAVE_LUASCRIPT"
619 Thanks to Jan-Piet Mens for the idea and proof-of-concept
620 implementation.
622 Tidied src/config.h to distinguish between
623 platform-dependent compile-time options which are selected
624 automatically, and builder-selectable compile time
625 options. Document the latter better, and describe how to
626 set them from the make command line.
628 Tidied up IPPROTO_IP/SOL_IP (and IPv6 equivalent)
629 confusion. IPPROTO_IP works everywhere now.
631 Set TOS on DHCP sockets, this improves things on busy
632 wireless networks. Thanks to Dave Taht for the patch.
634 Determine VERSION automatically based on git magic:
635 release tags or hash values.
637 Improve start-up speed when reading large hosts files
638 containing many distinct addresses.
640 Fix problem if dnsmasq is started without the stdin,
641 stdout and stderr file descriptors open. This can manifest
642 itself as 100% CPU use. Thanks to Chris Moore for finding
643 this.
645 Fix shell-scripting bug in bld/pkg-wrapper. Thanks to
646 Mark Mitchell for the patch.
648 Allow the TFP server or boot server in --pxe-service, to
649 be a domain name instead of an IP address. This allows for
650 round-robin to multiple servers, in the same way as
651 --dhcp-boot. A good suggestion from Cristiano Cumer.
653 Support BUILDDIR variable in the Makefile. Allows builds
654 for multiple archs from the same source tree with eg.
655 make BUILDDIR=linux (relative to dnsmasq tree)
656 make BUILDDIR=/tmp/openbsd (absolute path)
657 If BUILDDIR is not set, compilation happens in the src
658 directory, as before. Suggestion from Mark Mitchell.
660 Support DHCPv6. Support is there for the sort of things
661 the existing v4 server does, including tags, options,
662 static addresses and relay support. Missing is prefix
663 delegation, which is probably not required in the dnsmasq
664 niche, and an easy way to accept prefix delegations from
665 an upstream DHCPv6 server, which is. Future plans include
666 support for DHCPv6 router option and MAC address option
667 (to make selecting clients by MAC address work like IPv4).
668 These will be added as the standards mature.
669 This code has been tested, but this is the first release,
670 so don't bet the farm on it just yet. Many thanks to all
671 testers who have got it this far.
673 Support IPv6 router advertisements. This is a
674 simple-minded implementation, aimed at providing the
675 vestigial RA needed to go alongside IPv6. Is picks up
676 configuration from the DHCPv6 conf, and should just need
677 enabling with --enable-ra.
679 Fix long-standing wrinkle with --localise-queries that
680 could result in wrong answers when DNS packets arrive
681 via an interface other than the expected one. Thanks to
682 Lorenzo Milesi and John Hanks for spotting this one.
684 Update French translation. Thanks to Gildas Le Nadan.
686 Update Polish translation. Thanks to Jan Psota.
689 version 2.59
690 Fix regression in 2.58 which caused failure to start up
691 with some combinations of dnsmasq config and IPv6 kernel
692 network config. Thanks to Brielle Bruns for the bug
693 report.
695 Improve dnsmasq's behaviour when network interfaces are
696 still doing duplicate address detection (DAD). Previously,
697 dnsmasq would wait up to 20 seconds at start-up for the
698 DAD state to terminate. This is broken for bridge
699 interfaces on recent Linux kernels, which don't start DAD
700 until the bridge comes up, and so can take arbitrary
701 time. The new behaviour lets dnsmasq poll for an arbitrary
702 time whilst providing service on other interfaces. Thanks
703 to Stephen Hemminger for pointing out the problem.
706 version 2.58
707 Provide a definition of the SA_SIZE macro where it's
708 missing. Fixes build failure on openBSD.
710 Don't include a zero terminator at the end of messages
711 sent to /dev/log when /dev/log is a datagram socket.
712 Thanks to Didier Rabound for spotting the problem.
714 Add --dhcp-sequential-ip flag, to force allocation of IP
715 addresses in ascending order. Note that the default
716 pseudo-random mode is in general better but some
717 server-deployment applications need this.
719 Fix problem where a server-id of 0.0.0.0 is sent to a
720 client when a dhcp-relay is in use if a client renews a
721 lease after dnsmasq restart and before any clients on the
722 subnet get a new lease. Thanks to Mike Ruiz for assistance
723 in chasing this one down.
725 Don't return NXDOMAIN to an AAAA query if we have CNAME
726 which points to an A record only: NODATA is the correct
727 reply in this case. Thanks to Tom Fernandes for spotting
728 the problem.
730 Relax the need to supply a netmask in --dhcp-range for
731 networks which use a DHCP relay. Whilst this is still
732 desireable, in the absence of a netmask dnsmasq will use
733 a default based on the class (A, B, or C) of the address.
734 This should at least remove a cause of mysterious failure
735 for people using RFC1918 addresses and relays.
737 Add support for Linux conntrack connection marking. If
738 enabled with --conntrack, the connection mark for incoming
739 DNS queries will be copied to the outgoing connections
740 used to answer those queries. This allows clever firewall
741 and accounting stuff. Only available if dnsmasq is
742 compiled with HAVE_CONNTRACK and adds a dependency on
743 libnetfilter-conntrack. Thanks to Ed Wildgoose for the
744 initial idea, testing and sponsorship of this function.
746 Provide a sane error message when someone attempts to
747 match a tag in --dhcp-host.
749 Tweak the behaviour of --domain-needed, to avoid problems
750 with recursive nameservers downstream of dnsmasq. The new
751 behaviour only stops A and AAAA queries, and returns
752 NODATA rather than NXDOMAIN replies.
754 Efficiency fix for very large DHCP configurations, thanks
755 to James Gartrell and Mike Ruiz for help with this.
757 Allow the TFTP-server address in --dhcp-boot to be a
758 domain-name which is looked up in /etc/hosts. This can
759 give multiple IP addresses which are used round-robin,
760 thus doing TFTP server load-balancing. Thanks to Sushil
761 Agrawal for the patch.
763 When two tagged dhcp-options for a particular option
764 number are both valid, use the one which is valid without
765 a tag from the dhcp-range. Allows overriding of the value
766 of a DHCP option for a particular host as well as
767 per-network values. So
768 --dhcp-range=set:interface1,......
769 --dhcp-host=set:myhost,.....
770 --dhcp-option=tag:interface1,option:nis-domain,"domain1"
771 --dhcp-option=tag:myhost,option:nis-domain,"domain2"
772 will set the NIS-domain to domain1 for hosts in the range, but
773 override that to domain2 for a particular host.
775 Fix bug which resulted in truncated files and timeouts for
776 some TFTP transfers. The bug only occurs with netascii
777 transfers and needs an unfortunate relationship between
778 file size, blocksize and the number of newlines in the
779 last block before it manifests itself. Many thanks to
780 Alkis Georgopoulos for spotting the problem and providing
781 a comprehensive test-case.
783 Fix regression in TFTP server on *BSD platforms introduced
784 in version 2.56, due to confusion with sockaddr
785 length. Many thanks to Loic Pefferkorn for finding this.
787 Support scope-ids in IPv6 addresses of nameservers from
788 /etc/resolv.conf and in --server options. Eg
789 nameserver fe80::202:a412:4512:7bbf%eth0 or
790 server=fe80::202:a412:4512:7bbf%eth0. Thanks to
791 Michael Stapelberg for the suggestion.
793 Update Polish translation, thanks to Jan Psota.
795 Update French translation. Thanks to Gildas Le Nadan.
798 version 2.57
799 Add patches to allow build under Android.
801 Provide our own header for the DNS protocol, rather than
802 relying on arpa/nameser.h. This has proved more or less
803 defective over the years and the final straw is that it's
804 effectively empty on Android.
806 Fix regression in 2.56 which caused hex constants in
807 configuration to be rejected if they contain the '*'
808 wildcard.
810 Correct wrong casts of arguments to ctype.h functions,
811 isdigit(), isxdigit() etc. Thanks to Matthias Andree for
812 spotting this.
814 Allow build with IDN support independently from i18n.
815 IDN support continues to be included automatically
816 when i18n is included.
817 'make COPTS=-DHAVE_IDN' is the magic incantation.
819 Modify check on extraneous command line junk (added in
820 2.56) so that it doesn't complain about extra _empty_
821 arguments. Otherwise this breaks libvirt.
824 version 2.56
825 Add a patch to allow dnsmasq to get interface names right in a
826 Solaris zone. Thanks to Dj Padzensky for this.
828 Improve data-type parsing heuristics so that
829 --dhcp-option=option:domain-search,.
830 treats the value as a string and not an IP address.
831 Thanks to Clemens Fischer for spotting that.
833 Add IPv6 support to the TFTP server. Many thanks to Jan
834 'RedBully' Seiffert for the patches.
836 Log DNS queries at level LOG_INFO, rather then
837 LOG_DEBUG. This makes things consistent with DHCP
838 logging. Thanks to Adam Pribyl for spotting the problem.
840 Ensure that dnsmasq terminates cleanly when using
841 --syslog-async even if it cannot make a connection to the
842 syslogd.
844 Add --add-mac option. This is to support currently
845 experimental DNS filtering facilities. Thanks to Benjamin
846 Petrin for the orignal patch.
848 Fix bug which meant that tags were ignored in dhcp-range
849 configuration specifying PXE-proxy service. Thanks to
850 Cristiano Cumer for spotting this.
852 Raise an error if there is extra junk, not part of an
853 option, on the command line.
855 Flag a couple of log messages in cache.c as coming from
856 the DHCP subsystem. Thanks to Olaf Westrik for the patch.
858 Omit timestamps from logs when a) logging to stderr and
859 b) --keep-in-forground is set. The logging facility on the
860 other end of stderr can be assumned to supply them. Thanks
861 to John Hallam for the patch.
863 Don't complain about strings longer than 255 characters in
864 --txt-record, just split the long strings into 255
865 character chunks instead.
867 Fix crash on double-free. This bug can only happen when
868 dhcp-script is in use and then only in rare circumstances
869 triggered by high DHCP transaction rate and a slow
870 script. Thanks to Ferenc Wagner for finding the problem.
872 Only log that a file has been sent by TFTP after the
873 transfer has completed succesfully.
875 A good suggestion from Ferenc Wagner: extend
876 the --domain option to allow this sort of thing:
877 --domain=thekelleys.org.uk,192.168.0.0/24,local
878 which automatically creates
879 --local=/thekelleys.org.uk/
880 --local=/0.168.192.in-addr.arpa/
882 Tighten up syntax checking of hex contants in the config
883 file. Thanks to Fred Damen for spotting this.
885 Add dnsmasq logo/icon, contributed by Justin Swift. Many
886 thanks for that.
888 Never cache DNS replies which have the 'cd' bit set, or
889 which result from queries forwarded with the 'cd' bit
890 set. The 'cd' bit instructs a DNSSEC validating server
891 upstream to ignore signature failures and return replies
892 anyway. Without this change it's possible to pollute the
893 dnsmasq cache with bad data by making a query with the
894 'cd' bit set and subsequent queries would return this data
895 without its being marked as suspect. Thanks to Anders
896 Kaseorg for pointing out this problem.
898 Add --proxy-dnssec flag, for compliance with RFC
899 4035. Dnsmasq will now clear the 'ad' bit in answers returned
900 from upstream validating nameservers unless this option is
901 set.
903 Allow a filename of "-" for --conf-file to read
904 stdin. Suggestion from Timothy Redaelli.
906 Rotate the order of SRV records in replies, to provide
907 round-robin load balancing when all the priorities are
908 equal. Thanks to Peter McKinney for the suggestion.
910 Edit
911 contrib/MacOSX-launchd/uk.org.thekelleys.dnsmasq.plist
912 so that it doesn't log all queries to a file by
913 default. Thanks again to Peter McKinney.
915 By default, setting an IPv4 address for a domain but not
916 an IPv6 address causes dnsmasq to return
917 an NODATA reply for IPv6 (or vice-versa). So
918 --address=/google.com/1.2.3.4 stops IPv6 queries for
919 *google.com from being forwarded. Make it possible to
920 override this behaviour by defining the sematics if the
921 same domain appears in both --server and --address.
922 In that case, the --address has priority for the address
923 family in which is appears, but the --server has priority
924 of the address family which doesn't appear in --adddress
925 So:
926 --address=/google.com/1.2.3.4
927 --server=/google.com/#
928 will return 1.2.3.4 for IPv4 queries for *.google.com but
929 forward IPv6 queries to the normal upstream nameserver.
930 Similarly when setting an IPv6 address
931 only this will allow forwarding of IPv4 queries. Thanks to
932 William for pointing out the need for this.
934 Allow more than one --dhcp-optsfile and --dhcp-hostsfile
935 and make them understand directories as arguments in the
936 same way as --addn-hosts. Suggestion from John Hanks.
938 Ignore rebinding requests for leases we don't know
939 about. Rebind is broadcast, so we might get to overhear a
940 request meant for another DHCP server. NAKing this is
941 wrong. Thanks to Brad D'Hondt for assistance with this.
943 Fix cosmetic bug which produced strange output when
944 dumping cache statistics with some configurations. Thanks
945 to Fedor Kozhevnikov for spotting this.
948 version 2.55
949 Fix crash when /etc/ethers is in use. Thanks to
950 Gianluigi Tiesi for finding this.
952 Fix crash in netlink_multicast(). Thanks to Arno Wald for
953 finding this one.
955 Allow the empty domain "." in dhcp domain-search (119)
956 options.
959 version 2.54
960 There is no version 2.54 to avoid confusion with 2.53,
961 which incorrectly identifies itself as 2.54.
964 version 2.53
965 Fix failure to compile on Debian/kFreeBSD. Thanks to
966 Axel Beckert and Petr Salinger.
968 Fix code to avoid scary strict-aliasing warnings
969 generated by gcc 4.4.
971 Added FAQ entry warning about DHCP failures with Vista
972 when firewalls block 255.255.255.255.
974 Fixed bug which caused bad things to happen if a
975 resolv.conf file which exists is subsequently removed.
976 Thanks to Nikolai Saoukh for the patch.
978 Rationalised the DHCP tag system. Every configuration item
979 which can set a tag does so by adding "set:<tag>" and
980 every configuration item which is conditional on a tag is
981 made so by "tag:<tag>". The NOT operator changes to '!',
982 which is a bit more intuitive too. Dhcp-host directives
983 can set more than one tag now. The old '#' NOT,
984 "net:" prefix and no-prefixes are still honoured, so
985 no existing config file needs to be changed, but
986 the documentation and new-style config files should be
987 much less confusing.
989 Added --tag-if to allow boolean operations on tags.
990 This allows complicated logic to be clearer and more
991 general. A great suggestion from Richard Voigt.
993 Add broadcast/unicast information to DHCP logging.
995 Allow --dhcp-broadcast to be unconditional.
997 Fixed incorrect behaviour with NOT <tag> conditionals in
998 dhcp-options. Thanks to Max Turkewitz for assistance
999 finding this.
1001 If we send vendor-class encapsulated options based on the
1002 vendor-class supplied by the client, and no explicit
1003 vendor-class option is given, echo back the vendor-class
1004 from the client.
1006 Fix bug which stopped dnsmasq from matching both a
1007 circuitid and a remoteid. Thanks to Ignacio Bravo for
1008 finding this.
1010 Add --dhcp-proxy, which makes it possible to configure
1011 dnsmasq to use a DHCP relay agent as a full proxy, with
1012 all DHCP messages passing through the proxy. This is
1013 useful if the relay adds extra information to the packets
1014 it forwards, but cannot be configured with the RFC 5107
1015 server-override option.
1017 Added interface:<iface name> part to dhcp-range. The
1018 semantics of this are very odd at first sight, but it
1019 allows a single line of the form
1020 dhcp-range=interface:virt0,192.168.0.4,192.168.0.200
1021 to be added to dnsmasq configuration which then supplies
1022 DHCP and DNS services to that interface, without affecting
1023 what services are supplied to other interfaces and
1024 irrespective of the existance or lack of
1025 interface=<interface>
1026 lines elsewhere in the dnsmasq configuration. The idea is
1027 that such a line can be added automatically by libvirt
1028 or equivalent systems, without disturbing any manual
1029 configuration.
1031 Similarly to the above, allow --enable-tftp=<interface>
1033 Allow a TFTP root to be set separately for requests via
1034 different interfaces, --tftp-root=<path>,<interface>
1036 Correctly handle and log clashes between CNAMES and
1037 DNS names being given to DHCP leases. This fixes a bug
1038 which caused nonsense IP addresses to be logged. Thanks to
1039 Sergei Zhirikov for finding and analysing the problem.
1041 Tweak flush_log so as to avoid leaving the log
1042 file in non-blocking mode. O_NONBLOCK is a property of the
1043 file, not the process/descriptor.
1045 Fix contrib/Solaris10/create_package
1046 (/usr/man -> /usr/share/man) Thanks to Vita Batrla.
1048 Fix a problem where, if a client got a lease, then went
1049 to another subnet and got another lease, then moved back,
1050 it couldn't resume the old lease, but would instead get
1051 a new address. Thanks to Leonardo Rodrigues for spotting
1052 this and testing the fix.
1054 Fix weird bug which sometimes omitted certain characters
1055 from the start of quoted strings in dhcp-options. Thanks
1056 to Dayton Turner for spotting the problem.
1058 Add facility to redirect some domains to the standard
1059 upstream servers: this allows something like
1060 --server=/google.com/1.2.3.4 --server=/www.google.com/#
1061 which will send queries for *.google.com to 1.2.3.4,
1062 except *www.google.com which will be forwarded as usual.
1063 Thanks to AJ Weber for prompting this addition.
1065 Improve the hash-algorithm used to generate IP addresses
1066 from MAC addresses during initial DHCP address
1067 allocation. This improves performance when large numbers
1068 of hosts with similar MAC addresses all try and get an IP
1069 address at the same time. Thanks to Paul Smith for his
1070 work on this.
1072 Tweak DHCP code so that --bridge-interface can be used to
1073 select which IP alias of an interface should be used for
1074 DHCP purposes on Linux. If eth0 has an alias eth0:dhcp
1075 then adding --bridge-interface=eth0:dhcp,eth0 will use
1076 the address of eth0:dhcp to determine the correct subnet
1077 for DHCP address allocation. Thanks to Pawel Golaszewski
1078 for prompting this and Eric Cooper for further testing.
1080 Add --dhcp-generate-names. Suggestion by Ferenc Wagner.
1082 Tweak DNS server selection algorithm when there is more
1083 than one server available for a domain, eg.
1084 --server=/mydomain/1.1.1.1
1085 --server=/mydomain/2.2.2.2
1086 Thanks to Alberto Cuesta-Canada for spotting a weakness
1087 here.
1089 Add --max-ttl. Thanks to Fredrik Ringertz for the patch.
1091 Allow --log-facility=- to force all logging to
1092 stderr. Suggestion from Clemens Fischer.
1094 Fix regression which caused configuration like
1095 --address=/.domain.com/1.2.3.4 to be rejected. The dot to the
1096 left of the domain has been implied and not required for a
1097 long time, but it should be accepted for backward
1098 compatibility. Thanks to Andrew Burcin for spotting this.
1100 Add --rebind-domain-ok and --rebind-localhost-ok.
1101 Suggestion from Clemens Fischer.
1103 Log replies to queries of type TXT, when --log-queries
1104 is set.
1106 Fix compiler warnings when compiled with -DNO_DHCP. Thanks
1107 to Shantanu Gadgil for the patch.
1109 Updated French translation. Thanks to Gildas Le Nadan.
1111 Updated Polish translation. Thanks to Jan Psota.
1113 Updated German translation. Thanks to Matthias Andree.
1115 Added contrib/static-arp, thanks to Darren Hoo.
1117 Fix corruption of the domain when a name from /etc/hosts
1118 overrides one supplied by a DHCP client. Thanks to Fedor
1119 Kozhevnikov for spotting the problem.
1121 Updated Spanish translation. Thanks to Chris Chatham.
1124 version 2.52
1125 Work around a Linux kernel bug which insists that the
1126 length of the option passed to setsockopt must be at least
1127 sizeof(int) bytes, even if we're calling SO_BINDTODEVICE
1128 and the device name is "lo". Note that this is fixed
1129 in kernel 2.6.31, but the workaround is harmless and
1130 allows earlier kernels to be used. Also fix dnsmasq
1131 bug which reported the wrong address when this failed.
1132 Thanks to Fedor for finding this.
1134 The API for IPv6 PKTINFO changed around Linux kernel
1135 2.6.14. Workaround the case where dnsmasq is compiled
1136 against newer headers, but then run on an old kernel:
1137 necessary for some *WRT distros.
1139 Re-read the set of network interfaces when re-loading
1140 /etc/resolv.conf if --bind-interfaces is not set. This
1141 handles the case that loopback interfaces do not exist
1142 when dnsmasq is first started.
1144 Tweak the PXE code to support port 4011. This should
1145 reduce broadcasts and make things more reliable when other
1146 servers are around. It also improves inter-operability
1147 with certain clients.
1149 Make a pxe-service configuration with no filename or boot
1150 service type legal: this does a local boot. eg.
1151 pxe-service=x86PC, "Local boot"
1153 Be more conservative in detecting "A for A"
1154 queries. Dnsmasq checks if the name in a type=A query looks
1155 like a dotted-quad IP address and answers the query itself
1156 if so, rather than forwarding it. Previously dnsmasq
1157 relied in the library function inet_addr() to convert
1158 addresses, and that will accept some things which are
1159 confusing in this context, like 1.2.3 or even just
1160 1234. Now we only do A for A processing for four decimal
1161 numbers delimited by dots.
1163 A couple of tweaks to fix compilation on Solaris. Thanks
1164 to Joel Macklow for help with this.
1166 Another Solaris compilation tweak, needed for Solaris
1167 2009.06. Thanks to Lee Essen for that.
1169 Added extract packaging stuff from Lee Essen to
1170 contrib/Solaris10.
1172 Increased the default limit on number of leases to 1000
1173 (from 150). This is mainly a defence against DoS attacks,
1174 and for the average "one for two class C networks"
1175 installation, IP address exhaustion does that just as
1176 well. Making the limit greater than the number of IP
1177 addresses available in such an installation removes a
1178 surprise which otherwise can catch people out.
1180 Removed extraneous trailing space in the value of the
1181 DNSMASQ_TIME_REMAINING DNSMASQ_LEASE_LENGTH and
1182 DNSMASQ_LEASE_EXPIRES environment variables. Thanks to
1183 Gildas Le Nadan for spotting this.
1185 Provide the network-id tags for a DHCP transaction to
1186 the lease-change script in the environment variable
1187 DNSMASQ_TAGS. A good suggestion from Gildas Le Nadan.
1189 Add support for RFC3925 "Vendor-Identifying Vendor
1190 Options". The syntax looks like this:
1191 --dhcp-option=vi-encap:<enterprise number>, .........
1193 Add support to --dhcp-match to allow matching against
1194 RFC3925 "Vendor-Identifying Vendor Classes". The syntax
1195 looks like this:
1196 --dhcp-match=tag,vi-encap<enterprise number>, <value>
1198 Add some application specific code to assist in
1199 implementing the Broadband forum TR069 CPE-WAN
1200 specification. The details are in contrib/CPE-WAN/README
1202 Increase the default DNS packet size limit to 4096, as
1203 recommended by RFC5625 section 4.4.3. This can be
1204 reconfigured using --edns-packet-max if needed. Thanks to
1205 Francis Dupont for pointing this out.
1207 Rewrite query-ids even for TSIG signed packets, since
1208 this is allowed by RFC5625 section 4.5.
1210 Use getopt_long by default on OS X. It has been supported
1211 since version 10.3.0. Thanks to Arek Dreyer for spotting
1212 this.
1214 Added up-to-date startup configuration for MacOSX/launchd
1215 in contrib/MacOSX-launchd. Thanks to Arek Dreyer for
1216 providing this.
1218 Fix link error when including Dbus but excluding DHCP.
1219 Thanks to Oschtan for the bug report.
1221 Updated French translation. Thanks to Gildas Le Nadan.
1223 Updated Polish translation. Thanks to Jan Psota.
1225 Updated Spanish translation. Thanks to Chris Chatham.
1227 Fixed confusion about domains, when looking up DHCP hosts
1228 in /etc/hosts. This could cause spurious "Ignoring
1229 domain..." messages. Thanks to Fedor Kozhevnikov for
1230 finding and analysing the problem.
1233 version 2.51
1234 Add support for internationalised DNS. Non-ASCII characters
1235 in domain names found in /etc/hosts, /etc/ethers and
1236 /etc/dnsmasq.conf will be correctly handled by translation to
1237 punycode, as specified in RFC3490. This function is only
1238 available if dnsmasq is compiled with internationalisation
1239 support, and adds a dependency on GNU libidn. Without i18n
1240 support, dnsmasq continues to be compilable with just
1241 standard tools. Thanks to Yves Dorfsman for the
1242 suggestion.
1244 Add two more environment variables for lease-change scripts:
1245 First, DNSMASQ_SUPPLIED_HOSTNAME; this is set to the hostname
1246 supplied by a client, even if the actual hostname used is
1247 over-ridden by dhcp-host or dhcp-ignore-names directives.
1248 Also DNSMASQ_RELAY_ADDRESS which gives the address of
1249 a DHCP relay, if used.
1250 Suggestions from Michael Rack.
1252 Fix regression which broke echo of relay-agent
1253 options. Thanks to Michael Rack for spotting this.
1255 Don't treat option 67 as being interchangeable with
1256 dhcp-boot parameters if it's specified as
1257 dhcp-option-force.
1259 Make the code to call scripts on lease-change compile-time
1260 optional. It can be switched off by editing src/config.h
1261 or building with "make COPTS=-DNO_SCRIPT".
1263 Make the TFTP server cope with filenames from Windows/DOS
1264 which use '\' as pathname separator. Thanks to Ralf for
1265 the patch.
1267 Updated Polish translation. Thanks to Jan Psota.
1269 Warn if an IP address is duplicated in /etc/ethers. Thanks
1270 to Felix Schwarz for pointing this out.
1272 Teach --conf-dir to take an option list of file suffices
1273 which will be ignored when scanning the directory. Useful
1274 for backup files etc. Thanks to Helmut Hullen for the
1275 suggestion.
1277 Add new DHCP option named tftpserver-address, which
1278 corresponds to the third argument of dhcp-boot. This
1279 allows the complete functionality of dhcp-boot to be
1280 replicated with dhcp-option. Useful when using
1281 dhcp-optsfile.
1283 Test which upstream nameserver to use every 10 seconds
1284 or 50 queries and not just when a query times out and
1285 is retried. This should improve performance when there
1286 is a slow nameserver in the list. Thanks to Joe for the
1287 suggestion.
1289 Don't do any PXE processing, even for clients with the
1290 correct vendorclass, unless at least one pxe-prompt or
1291 pxe-service option is given. This stops dnsmasq
1292 interfering with proxy PXE subsystems when it is just
1293 the DHCP server. Thanks to Spencer Clark for spotting this.
1295 Limit the blocksize used for TFTP transfers to a value
1296 which avoids packet fragmentation, based on the MTU of the
1297 local interface. Many netboot ROMs can't cope with
1298 fragmented packets.
1300 Honour dhcp-ignore configuration for PXE and proxy-PXE
1301 requests. Thanks to Niels Basjes for the bug report.
1303 Updated French translation. Thanks to Gildas Le Nadan.
1306 version 2.50
1307 Fix security problem which allowed any host permitted to
1308 do TFTP to possibly compromise dnsmasq by remote buffer
1309 overflow when TFTP enabled. Thanks to Core Security
1310 Technologies and Iván Arce, Pablo Hernán Jorge, Alejandro
1311 Pablo Rodriguez, Martín Coco, Alberto Soliño Testa and
1312 Pablo Annetta. This problem has Bugtraq id: 36121
1313 and CVE: 2009-2957
1315 Fix a problem which allowed a malicious TFTP client to
1316 crash dnsmasq. Thanks to Steve Grubb at Red Hat for
1317 spotting this. This problem has Bugtraq id: 36120 and
1318 CVE: 2009-2958
1321 version 2.49
1322 Fix regression in 2.48 which disables the lease-change
1323 script. Thanks to Jose Luis Duran for spotting this.
1325 Log TFTP "file not found" errors. These were not logged,
1326 since a normal PXELinux boot generates many of them, but
1327 the lack of the messages seems to be more confusing than
1328 routinely seeing them when there is no real error.
1330 Update Spanish translation. Thanks to Chris Chatham.
1333 version 2.48
1334 Archived the extensive, backwards, changelog to
1335 CHANGELOG.archive. The current changelog now runs from
1336 version 2.43 and runs conventionally.
1338 Fixed bug which broke binding of servers to physical
1339 interfaces when interface names were longer than four
1340 characters. Thanks to MURASE Katsunori for the patch.
1342 Fixed netlink code to check that messages come from the
1343 correct source, and not another userspace process. Thanks
1344 to Steve Grubb for the patch.
1346 Maintainability drive: removed bug and missing feature
1347 workarounds for some old platforms. Solaris 9, OpenBSD
1348 older than 4.1, Glibc older than 2.2, Linux 2.2.x and
1349 DBus older than 1.1.x are no longer supported.
1351 Don't read included configuration files more than once:
1352 allows complex configuration structures without problems.
1354 Mark log messages from the various subsystems in dnsmasq:
1355 messages from the DHCP subsystem now have the ident string
1356 "dnsmasq-dhcp" and messages from TFTP have ident
1357 "dnsmasq-tftp". Thanks to Olaf Westrik for the patch.
1359 Fix possible infinite DHCP protocol loop when an IP
1360 address nailed to a hostname (not a MAC address) and a
1361 host sometimes provides the name, sometimes not.
1363 Allow --addn-hosts to take a directory: all the files
1364 in the directory are read. Thanks to Phil Cornelius for
1365 the suggestion.
1367 Support --bridge-interface on all platforms, not just BSD.
1369 Added support for advanced PXE functions. It's now
1370 possible to define a prompt and menu options which will
1371 be displayed when a client PXE boots. It's also possible to
1372 hand-off booting to other boot servers. Proxy-DHCP, where
1373 dnsmasq just supplies the PXE information and another DHCP
1374 server does address allocation, is also allowed. See the
1375 --pxe-prompt and --pxe-service keywords. Thanks to
1376 Alkis Georgopoulos for the suggestion and Guilherme Moro
1377 and Michael Brown for assistance.
1379 Improvements to DHCP logging. Thanks to Tom Metro for
1380 useful suggestions.
1382 Add ability to build dnsmasq without DHCP support. To do
1383 this, edit src/config.h or build with
1384 "make COPTS=-DNO_DHCP". Thanks to Mahavir Jain for the patch.
1386 Added --test command-line switch - syntax check
1387 configuration files only.
1389 Updated French translation. Thanks to Gildas Le Nadan.
1392 version 2.47
1393 Updated French translation. Thanks to Gildas Le Nadan.
1395 Fixed interface enumeration code to work on NetBSD
1396 5.0. Thanks to Roy Marples for the patch.
1398 Updated config.h to use the same location for the lease
1399 file on NetBSD as the other *BSD variants. Also allow
1400 LEASEFILE and CONFFILE symbols to be overriden in CFLAGS.
1402 Handle duplicate address detection on IPv6 more
1403 intelligently. In IPv6, an interface can have an address
1404 which is not usable, because it is still undergoing DAD
1405 (such addresses are marked "tentative"). Attempting to
1406 bind to an address in this state returns an error,
1407 EADDRNOTAVAIL. Previously, on getting such an error,
1408 dnsmasq would silently abandon the address, and never
1409 listen on it. Now, it retries once per second for 20
1410 seconds before generating a fatal error. 20 seconds should
1411 be long enough for any DAD process to complete, but can be
1412 adjusted in src/config.h if necessary. Thanks to Martin
1413 Krafft for the bug report.
1415 Add DBus introspection. Patch from Jeremy Laine.
1417 Update Dbus configuration file. Patch from Colin Walters.
1418 Fix for this bug:
1419 http://bugs.freedesktop.org/show_bug.cgi?id=18961
1421 Support arbitrarily encapsulated DHCP options, suggestion
1422 and initial patch from Samium Gromoff. This is useful for
1423 (eg) gPXE, which expect all its private options to be
1424 encapsulated inside a single option 175. So, eg,
1426 dhcp-option = encap:175, 190, "iscsi-client0"
1427 dhcp-option = encap:175, 191, "iscsi-client0-secret"
1429 will provide iSCSI parameters to gPXE.
1431 Enhance --dhcp-match to allow testing of the contents of a
1432 client-sent option, as well as its presence. This
1433 application in mind for this is RFC 4578
1434 client-architecture specifiers, but it's generally useful.
1435 Joey Korkames suggested the enhancement.
1437 Move from using the IP_XMIT_IF ioctl to IP_BOUND_IF on
1438 OpenSolaris. Thanks to Bastian Machek for the heads-up.
1440 No longer complain about blank lines in
1441 /etc/ethers. Thanks to Jon Nelson for the patch.
1443 Fix binding of servers to physical devices, eg
1444 --server=/domain/1.2.3.4@eth0 which was broken from 2.43
1445 onwards unless --query-port=0 set. Thanks to Peter Naulls
1446 for the bug report.
1448 Reply to DHCPINFORM requests even when the supplied ciaddr
1449 doesn't fall in any dhcp-range. In this case it's not
1450 possible to supply a complete configuration, but
1451 individually-configured options (eg PAC) may be useful.
1453 Allow the source address of an alias to be a range:
1454 --alias=192.168.0.0,10.0.0.0,255.255.255.0 maps the whole
1455 subnet 192.168.0.0->192.168.0.255 to 10.0.0.0->10.0.0.255,
1456 as before.
1457 --alias=192.168.0.10-192.168.0.40,10.0.0.0,255.255.255.0
1458 maps only the 192.168.0.10->192.168.0.40 region. Thanks to
1459 Ib Uhrskov for the suggestion.
1461 Don't dynamically allocate DHCP addresses which may break
1462 Windows. Addresses which end in .255 or .0 are broken in
1463 Windows even when using supernetting.
1464 --dhcp-range=192.168.0.1,192.168.1.254,255,255,254.0 means
1465 192.168.0.255 is a valid IP address, but not for Windows.
1466 See Microsoft KB281579. We therefore no longer allocate
1467 these addresses to avoid hard-to-diagnose problems.
1469 Update Polish translation. Thanks to Jan Psota.
1471 Delete the PID-file when dnsmasq shuts down. Note that by
1472 this time, dnsmasq is normally not running as root, so
1473 this will fail if the PID-file is stored in a root-owned
1474 directory; such failure is silently ignored. To take
1475 advantage of this feature, the PID-file must be stored in a
1476 directory owned and write-able by the user running
1477 dnsmasq.
1480 version 2.46
1481 Allow --bootp-dynamic to take a netid tag, so that it may
1482 be selectively enabled. Thanks to Olaf Westrik for the
1483 suggestion.
1485 Remove ISC-leasefile reading code. This has been
1486 deprecated for a long time, and last time I removed it, it
1487 ended up going back by request of one user. This time,
1488 it's gone for good; otherwise it would need to be
1489 re-worked to support multiple domains (see below).
1491 Support DHCP clients in multiple DNS domains. This is a
1492 long-standing request. Clients are assigned to a domain
1493 based in their IP address.
1495 Add --dhcp-fqdn flag, which changes behaviour if DNS names
1496 assigned to DHCP clients. When this is set, there must be
1497 a domain associated with each client, and only
1498 fully-qualified domain names are added to the DNS. The
1499 advantage is that the only the FQDN needs to be unique,
1500 so that two or more DHCP clients can share a hostname, as
1501 long as they are in different domains.
1503 Set environment variable DNSMASQ_DOMAIN when invoking
1504 lease-change script. This may be useful information to
1505 have now that it's variable.
1507 Tighten up data-checking code for DNS packet
1508 handling. Thanks to Steve Dodd who found certain illegal
1509 packets which could crash dnsmasq. No memory overwrite was
1510 possible, so this is not a security issue beyond the DoS
1511 potential.
1513 Update example config dhcp option 47, the previous
1514 suggestion generated an illegal, zero-length,
1515 option. Thanks to Matthias Andree for finding this.
1517 Rewrite hosts-file reading code to remove the limit of
1518 1024 characters per line. John C Meuser found this.
1520 Create a net-id tag with the name of the interface on
1521 which the DHCP request was received.
1523 Fixed minor memory leak in DBus code, thanks to Jeremy
1524 Laine for the patch.
1526 Emit DBus signals as the DHCP lease database
1527 changes. Thanks to Jeremy Laine for the patch.
1529 Allow for more that one MAC address in a dhcp-host
1530 line. This configuration tells dnsmasq that it's OK to
1531 abandon a DHCP lease of the fixed address to one MAC
1532 address, if another MAC address in the dhcp-host statement
1533 asks for an address. This is useful to give a fixed
1534 address to a host which has two network interfaces
1535 (say, a laptop with wired and wireless interfaces.)
1536 It's very important to ensure that only one interface
1537 at a time is up, since dnsmasq abandons the first lease
1538 and re-uses the address before the leased time has
1539 elapsed. John Gray suggested this.
1541 Tweak the response to a DHCP request packet with a wrong
1542 server-id when --dhcp-authoritative is set; dnsmasq now
1543 returns a DHCPNAK, rather than silently ignoring the
1544 packet. Thanks to Chris Marget for spotting this
1545 improvement.
1547 Add --cname option. This provides a limited alias
1548 function, usable for DHCP names. Thanks to AJ Weber for
1549 suggestions on this.
1551 Updated contrib/webmin with latest version from Neil
1552 Fisher.
1554 Updated Polish translation. Thanks to Jan Psota.
1556 Correct the text names for DHCP options 64 and 65 to be
1557 "nis+-domain" and "nis+-servers".
1559 Updated Spanish translation. Thanks to Chris Chatham.
1561 Force re-reading of /etc/resolv.conf when an "interface
1562 up" event occurs.
1565 version 2.45
1566 Fix total DNS failure in release 2.44 unless --min-port
1567 specified. Thanks to Steven Barth and Grant Coady for
1568 bugreport. Also reject out-of-range port spec, which could
1569 break things too: suggestion from Gilles Espinasse.
1572 version 2.44
1573 Fix crash when unknown client attempts to renew a DHCP
1574 lease, problem introduced in version 2.43. Thanks to
1575 Carlos Carvalho for help chasing this down.
1577 Fix potential crash when a host which doesn't have a lease
1578 does DHCPINFORM. Again introduced in 2.43. This bug has
1579 never been reported in the wild.
1581 Fix crash in netlink code introduced in 2.43. Thanks to
1582 Jean Wolter for finding this.
1584 Change implementation of min_port to work even if min-port
1585 is large.
1587 Patch to enable compilation of latest Mac OS X. Thanks to
1588 David Gilman.
1590 Update Spanish translation. Thanks to Christopher Chatham.
1593 version 2.43
1594 Updated Polish translation. Thanks to Jan Psota.
1596 Flag errors when configuration options are repeated
1597 illegally.
1599 Further tweaks for GNU/kFreeBSD
1601 Add --no-wrap to msgmerge call - provides nicer .po file
1602 format.
1604 Honour lease-time spec in dhcp-host lines even for
1605 BOOTP. The user is assumed to known what they are doing in
1606 this case. (Hosts without the time spec still get infinite
1607 leases for BOOTP, over-riding the default in the
1608 dhcp-range.) Thanks to Peter Katzmann for uncovering this.
1610 Fix problem matching relay-agent ids. Thanks to Michael
1611 Rack for the bug report.
1613 Add --naptr-record option. Suggestion from Johan
1614 Bergquist.
1616 Implement RFC 5107 server-id-override DHCP relay agent
1617 option.
1619 Apply patches from Stefan Kruger for compilation on
1620 Solaris 10 under Sun studio.
1622 Yet more tweaking of Linux capability code, to suppress
1623 pointless wingeing from kernel 2.6.25 and above.
1625 Improve error checking during startup. Previously, some
1626 errors which occurred during startup would be worked
1627 around, with dnsmasq still starting up. Some were logged,
1628 some silent. Now, they all cause a fatal error and dnsmasq
1629 terminates with a non-zero exit code. The errors are those
1630 associated with changing uid and gid, setting process
1631 capabilities and writing the pidfile. Thanks to Uwe
1632 Gansert and the Suse security team for pointing out
1633 this improvement, and Bill Reimers for good implementation
1634 suggestions.
1636 Provide NO_LARGEFILE compile option to switch off largefile
1637 support when compiling against versions of uclibc which
1638 don't support it. Thanks to Stephane Billiart for the patch.
1640 Implement random source ports for interactions with
1641 upstream nameservers. New spoofing attacks have been found
1642 against nameservers which do not do this, though it is not
1643 clear if dnsmasq is vulnerable, since to doesn't implement
1644 recursion. By default dnsmasq will now use a different
1645 source port (and socket) for each query it sends
1646 upstream. This behaviour can suppressed using the
1647 --query-port option, and the old default behaviour
1648 restored using --query-port=0. Explicit source-port
1649 specifications in --server configs are still honoured.
1651 Replace the random number generator, for better
1652 security. On most BSD systems, dnsmasq uses the
1653 arc4random() RNG, which is secure, but on other platforms,
1654 it relied on the C-library RNG, which may be
1655 guessable and therefore allow spoofing. This release
1656 replaces the libc RNG with the SURF RNG, from Daniel
1657 J. Berstein's DJBDNS package.
1659 Don't attempt to change user or group or set capabilities
1660 if dnsmasq is run as a non-root user. Without this, the
1661 change from soft to hard errors when these fail causes
1662 problems for non-root daemons listening on high
1663 ports. Thanks to Patrick McLean for spotting this.
1665 Updated French translation. Thanks to Gildas Le Nadan.
1668 version 2.42
1669 The changelog for version 2.42 and earlier is
1670 available in CHANGELOG.archive.
