2 Use random addresses for DHCPv6 temporary address
3 allocations, instead of algorithmically determined stable
6 Fix bug which meant that the DHCPv6 DUID was not available
7 in DHCP script runs during the lifetime of the dnsmasq
8 process which created the DUID de-novo. Once the DUID was
9 created and stored in the lease file and dnsmasq
10 restarted, this bug disappeared.
12 Fix bug introduced in 2.67 which could result in erroneous
13 NXDOMAIN returns to CNAME queries.
15 Fix build failures on MacOS X and openBSD.
17 Allow subnet specifications in --auth-zone to be interface
18 names as well as address literals. This makes it possible
19 to configure authoritative DNS when local address ranges
20 are dynamic and works much better than the previous
21 work-around which exempted contructed DHCP ranges from the
22 IP address filtering. As a consequence, that work-around
23 is removed. Under certain circumstances, this change wil
24 break existing configuration: if you're relying on the
25 contructed-range exception, you need to change --auth-zone
26 to specify the same interface as is used to construct your
27 DHCP ranges, probably with a trailing "/6" like this:
28 --auth-zone=example.com,eth0/6 to limit the addresses to
29 IPv6 addresses of eth0.
31 Fix problems when advertising deleted IPv6 prefixes. If
32 the prefix is deleted (rather than replaced), it doesn't
33 get advertised with zero preferred time. Thanks to Tsachi
38 Fix crash if upstream server returns SERVFAIL when
39 --conntrack in use. Thanks to Giacomo Tazzari for finding
40 this and supplying the patch.
42 Repair regression in 2.64. That release stopped sending
43 lease-time information in the reply to DHCPINFORM
44 requests, on the correct grounds that it was a standards
45 violation. However, this broke the dnsmasq-specific
46 dhcp_lease_time utility. Now, DHCPINFORM returns
47 lease-time only if it's specifically requested
48 (maintaining standards) and the dhcp_lease_time utility
49 has been taught to ask for it (restoring functionality).
51 Fix --dhcp-match, --dhcp-vendorclass and --dhcp-userclass
52 to work with BOOTP and well as DHCP. Thanks to Peter
53 Korsgaard for spotting the problem.
55 Add --synth-domain. Thanks to Vishvananda Ishaya for
58 Fix failure to compile ipset.c if old kernel headers are
59 in use. Thanks to Eugene Rudoy for pointing this out.
61 Handle IPv4 interface-address labels in Linux. These are
62 often used to emulate the old IP-alias addresses. Before,
63 using --interface=eth0 would service all the addresses of
64 eth0, including ones configured as aliases, which appear
65 in ifconfig as eth0:0. Now, only addresses with the label
66 eth0 are active. This is not backwards compatible: if you
67 want to continue to bind the aliases too, you need to add
68 eg. --interface=eth0:0 to the config.
70 Fix "failed to set SO_BINDTODEVICE on DHCP socket: Socket
71 operation on non-socket" error on startup with
72 configurations which have exactly one --interface option
73 and do RA but _not_ DHCPv6. Thanks to Trever Adams for the
76 Generalise --interface-name to cope with IPv6 addresses
77 and multiple addresses per interface per address family.
79 Fix option parsing for --dhcp-host, which was generating a
80 spurious error when all seven possible items were
81 included. Thanks to Zhiqiang Wang for the bug report.
83 Remove restriction on prefix-length in --auth-zone. Thanks
84 to Toke Hoiland-Jorgensen for suggesting this.
86 Log when the maximum number of concurrent DNS queries is
87 reached. Thanks to Marcelo Salhab Brogliato for the patch.
89 If wildcards are used in --interface, don't assume that
90 there will only ever be one available interface for DHCP
91 just because there is one at start-up. More may appear, so
92 we can't use SO_BINDTODEVICE. Thanks to Natrio for the bug
95 Increase timeout/number of retries in TFTP to accomodate
96 AudioCodes Voice Gateways doing streaming writes to flash.
97 Thanks to Damian Kaczkowski for spotting the problem.
99 Fix crash with empty DHCP string options when adding zero
100 terminator. Thanks to Patrick McLean for the bug report.
102 Allow hostnames to start with a number, as allowed in
103 RFC-1123. Thanks to Kyle Mestery for the patch.
105 Fixes to DHCP FQDN option handling: don't terminate FQDN
106 if domain not known and allow a FQDN option with blank
107 name to request that a FQDN option is returned in the
108 reply. Thanks to Roy Marples for the patch.
110 Make --clear-on-reload apply to setting upstream servers
113 When the address which triggered the construction of an
114 advertised IPv6 prefix disappears, continue to advertise
115 the prefix for up to 2 hours, with the preferred lifetime
116 set to zero. This satisfies RFC 6204 4.3 L-13 and makes
117 things work better if a prefix disappears without being
118 deprecated first. Thanks to Uwe Schindler for persuasively
121 Fix MAC address enumeration on *BSD. Thanks to Brad Smith
124 Support RFC-4242 information-refresh-time options in the
125 reply to DHCPv6 information-request. The lease time of the
126 smallest valid dhcp-range is sent. Thanks to Uwe Schindler
129 Make --listen-address higher priority than --except-interface
130 in all circumstances. Thanks to Thomas Hood for the bugreport.
132 Provide independent control over which interfaces get TFTP
133 service. If enable-tftp is given a list of interfaces, then TFTP
134 is provided on those. Without the list, the previous behaviour
135 (provide TFTP to the same interfaces we provide DHCP to)
136 is retained. Thanks to Lonnie Abelbeck for the suggestion.
138 Add --dhcp-relay config option. Many thanks to vtsl.net
139 for sponsoring this development.
141 Fix crash with empty tag: in --dhcp-range. Thanks to
142 Kaspar Schleiser for the bug report.
144 Add "baseline" and "bloatcheck" makefile targets, for
145 revealing size changes during development. Thanks to
146 Vladislav Grishenko for the patch.
148 Cope with DHCPv6 clients which send REQUESTs without
149 address options - treat them as SOLICIT with rapid commit.
151 Support identification of clients by MAC address in
152 DHCPv6. When using a relay, the relay must support RFC
153 6939 for this to work. It always works for directly
154 connected clients. Thanks to Vladislav Grishenko
155 for prompting this feature.
157 Remove the rule for constructed DHCP ranges that the local
158 address must be either the first or last address in the
159 range. This was originally to avoid SLAAC addresses, but
160 we now explicitly autoconfig and privacy addresses instead.
162 Update Polish translation. Thanks to Jan Psota.
164 Fix problem in DHCPv6 vendorclass/userclass matching
165 code. Thanks to Tanguy Bouzeloc for the patch.
167 Update Spanish transalation. Thanks to Vicente Soriano.
169 Add --ra-param option. Thanks to Vladislav Grishenko for
172 Add --add-subnet configuration, to tell upstream DNS
173 servers where the original client is. Thanks to DNSthingy
174 for sponsoring this feature.
176 Add --quiet-dhcp, --quiet-dhcp6 and --quiet-ra. Thanks to
177 Kevin Darbyshire-Bryant for the initial patch.
179 Allow A/AAAA records created by --interface-name to be the
180 target of --cname. Thanks to Hadmut Danisch for the
183 Avoid treating a --dhcp-host which has an IPv6 address
184 as eligable for use with DHCPv4 on the grounds that it has
185 no address, and vice-versa. Thanks to Yury Konovalov for
186 spotting the problem.
188 Do a better job caching dangling CNAMEs. Thanks to Yves
189 Dorfsman for spotting the problem.
193 Add the ability to act as an authoritative DNS
194 server. Dnsmasq can now answer queries from the wider 'net
195 with local data, as long as the correct NS records are set
196 up. Only local data is provided, to avoid creating an open
197 DNS relay. Zone transfer is supported, to allow secondary
198 servers to be configured.
200 Add "constructed DHCP ranges" for DHCPv6. This is intended
201 for IPv6 routers which get prefixes dynamically via prefix
202 delegation. With suitable configuration, stateful DHCPv6
203 and RA can happen automatically as prefixes are delegated
204 and then deprecated, without having to re-write the
205 dnsmasq configuration file or restart the daemon. Thanks to
206 Steven Barth for extensive testing and development work on
209 Fix crash on startup on Solaris 11. Regression probably
210 introduced in 2.61. Thanks to Geoff Johnstone for the
213 Add code to make behaviour for TCP DNS requests that same
214 as for UDP requests, when a request arrives for an allowed
215 address, but via a banned interface. This change is only
216 active on Linux, since the relevant API is missing (AFAIK)
217 on other platforms. Many thanks to Tomas Hozza for
218 spotting the problem, and doing invaluable discovery of
219 the obscure and undocumented API required for the solution.
221 Don't send the default DHCP option advertising dnsmasq as
222 the local DNS server if dnsmasq is configured to not act
223 as DNS server, or it's configured to a non-standard port.
225 Add DNSMASQ_CIRCUIT_ID, DNSMASQ_SUBCRIBER_ID,
226 DNSMASQ_REMOTE_ID variables to the environment of the
227 lease-change script (and the corresponding Lua). These hold
228 information inserted into the DHCP request by a DHCP relay
229 agent. Thanks to Lakefield Communications for providing a
230 bounty for this addition.
232 Fixed crash, introduced in 2.64, whilst handling DHCPv6
233 information-requests with some common configurations.
234 Thanks to Robert M. Albrecht for the bug report and
237 Add --ipset option. Thanks to Jason A. Donenfeld for the
240 Don't erroneously reject some option names in --dhcp-match
241 options. Thanks to Benedikt Hochstrasser for the bug report.
243 Allow a trailing '*' wildcard in all interface-name
244 configurations. Thanks to Christian Parpart for the patch.
246 Handle the situation where libc headers define
247 SO_REUSEPORT, but the kernel in use doesn't, to cope with
248 the introduction of this option to Linux. Thanks to Rich
249 Felker for the bug report.
251 Update Polish translation. Thanks to Jan Psota.
253 Fix crash if the configured DHCP lease limit is
254 reached. Regression occurred in 2.61. Thanks to Tsachi for
257 Update the French translation. Thanks to Gildas le Nadan.
261 Fix regression which broke forwarding of queries sent via
262 TCP which are not for A and AAAA and which were directed to
263 non-default servers. Thanks to Niax for the bug report.
265 Fix failure to build with DHCP support excluded. Thanks to
266 Gustavo Zacarias for the patch.
268 Fix nasty regression in 2.64 which completely broke cacheing.
272 Handle DHCP FQDN options with all flag bits zero and
273 --dhcp-client-update set. Thanks to Bernd Krumbroeck for
274 spotting the problem.
276 Finesse the check for /etc/hosts names which conflict with
277 DHCP names. Previously a name/address pair in /etc/hosts
278 which didn't match the name/address of a DHCP lease would
279 generate a warning. Now that only happesn if there is not
280 also a match. This allows multiple addresses for a name in
281 /etc/hosts with one of them assigned via DHCP.
283 Fix broken vendor-option processing for BOOTP. Thanks to
284 Hans-Joachim Baader for the bug report.
286 Don't report spurious netlink errors, regression in
287 2.63. Thanks to Vladislav Grishenko for the patch.
289 Flag DHCP or DHCPv6 in starup logging. Thanks to
290 Vladislav Grishenko for the patch.
292 Add SetServersEx method in DBus interface. Thanks to Dan
293 Williams for the patch.
295 Add SetDomainServers method in DBus interface. Thanks to
296 Roy Marples for the patch.
298 Fix build with later Lua libraries. Thansk to Cristian
299 Rodriguez for the patch.
301 Add --max-cache-ttl option. Thanks to Dennis Kaarsemaker
304 Fix breakage of --host-record parsing, resulting in
305 infinte loop at startup. Regression in 2.63. Thanks to
306 Haim Gelfenbeyn for spotting this.
308 Set SO_REUSEADDRESS and SO_V6ONLY options on the DHCPv6
309 socket, this allows multiple instances of dnsmasq on a
310 single machine, in the same way as for DHCPv4. Thanks to
311 Gene Czarcinski and Vladislav Grishenko for work on this.
313 Fix DHCPv6 to do access control correctly when it's
314 configured with --listen-address. Thanks to
315 Gene Czarcinski for sorting this out.
317 Add a "wildcard" dhcp-range which works for any IPv6
318 subnet, --dhcp-range=::,static Useful for Stateless
319 DHCPv6. Thanks to Vladislav Grishenko for the patch.
321 Don't include lease-time in DHCPACK replies to DHCPINFORM
322 queries, since RFC-2131 says we shouldn't. Thanks to
323 Wouter Ibens for pointing this out.
325 Makefile tweak to do dependency checking on header files.
326 Thanks to Johan Peeters for the patch.
328 Check interface for outgoing unsolicited router
329 advertisements, rather than relying on interface address
330 configuration. Thanks to Gene Czarinski for the patch.
332 Handle better attempts to transmit on interfaces which are
333 still doing DAD, and specifically do not just transmit
334 without setting source address and interface, since this
335 can cause very puzzling effects when a router
336 advertisement goes astray. Thanks again to Gene Czarinski.
338 Get RA timers right when there is more than one
339 dhcp-range on a subnet.
343 Do duplicate dhcp-host address check in --test mode.
345 Check that tftp-root directories are accessible before
346 start-up. Thanks to Daniel Veillard for the initial patch.
348 Allow more than one --tfp-root flag. The per-interface
349 stuff is pointless without that.
351 Add --bind-dynamic. A hybrid mode between the default and
352 --bind-interfaces which copes with dynamically created
355 A couple of fixes to the build system for Android. Thanks
356 to Metin Kaya for the patches.
358 Remove the interface:<interface> argument in --dhcp-range, and
359 the interface argument to --enable-tftp. These were a
360 still-born attempt to allow automatic isolated
361 configuration by libvirt, but have never (to my knowledge)
362 been used, had very strange semantics, and have been
363 superceded by other mechanisms.
365 Fixed bug logging filenames when duplicate dhcp-host
366 addresses are found. Thanks to John Hanks for the patch.
368 Fix regression in 2.61 which broke caching of CNAME
369 chains. Thanks to Atul Gupta for the bug report.
371 Allow the target of a --cname flag to be another --cname.
373 Teach DHCPv6 about the RFC 4242 information-refresh-time
374 option, and add parsing if the minutes, hours and days
375 format for options. Thanks to Francois-Xavier Le Bail for
378 Allow "w" (for week) as multiplier in lease times, as well
379 as seconds, minutes, hours and days. Álvaro Gámez Machado
380 spotted the ommission.
382 Update French translation. Thanks to Gildas Le Nadan.
384 Allow a DBus service name to be given with --enable-dbus
385 which overrides the default,
386 uk.org.thekelleys.dnsmasq. Thanks to Mathieu
387 Trudel-Lapierre for the patch.
389 Set the "prefix on-link" bit in Router
390 Advertisements. Thanks to Gui Iribarren for the patch.
394 Update German translation. Thanks to Conrad Kostecki.
396 Cope with router-solict packets wich don't have a valid
397 source address. Thanks to Vladislav Grishenko for the patch.
399 Fixed bug which caused missing periodic router
400 advertisements with some configurations. Thanks to
401 Vladislav Grishenko for the patch.
403 Fixed bug which broke DHCPv6/RA with prefix lengths
404 which are not divisible by 8. Thanks to Andre Coetzee
407 Fix non-response to router-solicitations when
408 router-advertisement configured, but DHCPv6 not
409 configured. Thanks to Marien Zwart for the patch.
411 Add --dns-rr, to allow arbitrary DNS resource records.
413 Fixed bug which broke RA scheduling when an interface had
414 two addresses in the same network. Thanks to Jim Bos for
415 his help nailing this.
418 Re-write interface discovery code on *BSD to use
419 getifaddrs. This is more portable, more straightforward,
420 and allows us to find the prefix length for IPv6
423 Add ra-names, ra-stateless and slaac keywords for DHCPv6.
424 Dnsmasq can now synthesise AAAA records for dual-stack
425 hosts which get IPv6 addresses via SLAAC. It is also now
426 possible to use SLAAC and stateless DHCPv6, and to
427 tell clients to use SLAAC addresses as well as DHCP ones.
428 Thanks to Dave Taht for help with this.
430 Add --dhcp-duid to allow DUID-EN uids to be used.
432 Explicity send DHCPv6 replies to the correct port, instead
433 of relying on clients to send requests with the correct
434 source address, since at least one client in the wild gets
435 this wrong. Thanks to Conrad Kostecki for help tracking
438 Send a preference value of 255 in DHCPv6 replies when
439 --dhcp-authoritative is in effect. This tells clients not
440 to wait around for other DHCP servers.
442 Better logging of DHCPv6 options.
444 Add --host-record. Thanks to Rob Zwissler for the
447 Invoke the DHCP script with action "tftp" when a TFTP file
448 transfer completes. The size of the file, address to which
449 it was sent and complete pathname are supplied. Note that
450 version 2.60 introduced some script incompatibilties
451 associated with DHCPv6, and this is a further change. To
452 be safe, scripts should ignore unknown actions, and if
453 not IPv6-aware, should exit if the environment
454 variable DNSMASQ_IAID is set. The use-case for this is
455 to track netboot/install. Suggestion from Shantanu
458 Update contrib/port-forward/dnsmasq-portforward to reflect
461 Set the environment variable DNSMASQ_LOG_DHCP when running
462 the script id --log-dhcp is in effect, so that script can
463 taylor their logging verbosity. Suggestion from Malte
466 Arrange that addresses specified with --listen-address
467 work even if there is no interface carrying the
468 address. This is chiefly useful for IPv4 loopback
469 addresses, where any address in 127.0.0.0/8 is a valid
470 loopback address, but normally only 127.0.0.1 appears on
471 the lo interface. Thanks to Mathieu Trudel-Lapierre for
472 the idea and initial patch.
474 Fix crash, introduced in 2.60, when a DHCPINFORM is
475 received from a network which has no valid dhcp-range.
476 Thanks to Stephane Glondu for the bug report.
478 Add a new DHCP lease time keyword, "deprecated" for
479 --dhcp-range. This is only valid for IPv6, and sets the
480 preffered lease time for both DHCP and RA to zero. The
481 effect is that clients can continue to use the address
482 for existing connections, but new connections will use
483 other addresses, if they exist. This makes hitless
484 renumbering at least possible.
486 Fix bug in address6_available() which caused DHCPv6 lease
487 aquisition to fail if more than one dhcp-range in use.
489 Provide RDNSS and DNSSL data in router advertisements,
490 using the settings provided for DHCP options
491 option6:domain-search and option6:dns-server.
493 Tweak logo/favicon.ico to add some transparency. Thanks to
494 SamLT for work on this.
496 Don't cache data from non-recursive nameservers, since it
497 may erroneously look like a valid CNAME to a non-exitant
498 name. Thanks to Ben Winslow for finding this.
500 Call SO_BINDTODEVICE on the DHCP socket(s) when doing DHCP
501 on exactly one interface and --bind-interfaces is set. This
502 makes the OpenStack use-case of one dnsmasq per virtual
503 interface work. This is only available on Linux; it's not
504 supported on other platforms. Thanks to Vishvananda Ishaya
505 and the OpenStack team for the suggestion.
507 Updated French translation. Thanks to Gildas Le Nadan.
509 Give correct from-cache answers to explict CNAME queries.
510 Thanks to Rob Zwissler for spotting this.
512 Add --tftp-lowercase option. Thanks to Oliver Rath for the
515 Ensure that the DBus DhcpLeaseUpdated events are generated
516 when a lease goes through INIT_REBOOT state, even if the
517 dhcp-script is not in use. Thanks to Antoaneta-Ecaterina
520 Fix failure of TFTP over IPv4 on OpenBSD platform. Thanks
521 to Brad Smith for spotting this.
525 Fix compilation problem in Mac OS X Lion. Thanks to Olaf
526 Flebbe for the patch.
528 Fix DHCP when using --listen-address with an IP address
529 which is not the primary address of an interface.
531 Add --dhcp-client-update option.
533 Add Lua integration. Dnsmasq can now execute a DHCP
534 lease-change script written in Lua. This needs to be
535 enabled at compile time by setting HAVE_LUASCRIPT in
536 src/config.h or running "make COPTS=-DHAVE_LUASCRIPT"
537 Thanks to Jan-Piet Mens for the idea and proof-of-concept
540 Tidied src/config.h to distinguish between
541 platform-dependent compile-time options which are selected
542 automatically, and builder-selectable compile time
543 options. Document the latter better, and describe how to
544 set them from the make command line.
546 Tidied up IPPROTO_IP/SOL_IP (and IPv6 equivalent)
547 confusion. IPPROTO_IP works everywhere now.
549 Set TOS on DHCP sockets, this improves things on busy
550 wireless networks. Thanks to Dave Taht for the patch.
552 Determine VERSION automatically based on git magic:
553 release tags or hash values.
555 Improve start-up speed when reading large hosts files
556 containing many distinct addresses.
558 Fix problem if dnsmasq is started without the stdin,
559 stdout and stderr file descriptors open. This can manifest
560 itself as 100% CPU use. Thanks to Chris Moore for finding
563 Fix shell-scripting bug in bld/pkg-wrapper. Thanks to
564 Mark Mitchell for the patch.
566 Allow the TFP server or boot server in --pxe-service, to
567 be a domain name instead of an IP address. This allows for
568 round-robin to multiple servers, in the same way as
569 --dhcp-boot. A good suggestion from Cristiano Cumer.
571 Support BUILDDIR variable in the Makefile. Allows builds
572 for multiple archs from the same source tree with eg.
573 make BUILDDIR=linux (relative to dnsmasq tree)
574 make BUILDDIR=/tmp/openbsd (absolute path)
575 If BUILDDIR is not set, compilation happens in the src
576 directory, as before. Suggestion from Mark Mitchell.
578 Support DHCPv6. Support is there for the sort of things
579 the existing v4 server does, including tags, options,
580 static addresses and relay support. Missing is prefix
581 delegation, which is probably not required in the dnsmasq
582 niche, and an easy way to accept prefix delegations from
583 an upstream DHCPv6 server, which is. Future plans include
584 support for DHCPv6 router option and MAC address option
585 (to make selecting clients by MAC address work like IPv4).
586 These will be added as the standards mature.
587 This code has been tested, but this is the first release,
588 so don't bet the farm on it just yet. Many thanks to all
589 testers who have got it this far.
591 Support IPv6 router advertisements. This is a
592 simple-minded implementation, aimed at providing the
593 vestigial RA needed to go alongside IPv6. Is picks up
594 configuration from the DHCPv6 conf, and should just need
595 enabling with --enable-ra.
597 Fix long-standing wrinkle with --localise-queries that
598 could result in wrong answers when DNS packets arrive
599 via an interface other than the expected one. Thanks to
600 Lorenzo Milesi and John Hanks for spotting this one.
602 Update French translation. Thanks to Gildas Le Nadan.
604 Update Polish translation. Thanks to Jan Psota.
608 Fix regression in 2.58 which caused failure to start up
609 with some combinations of dnsmasq config and IPv6 kernel
610 network config. Thanks to Brielle Bruns for the bug
613 Improve dnsmasq's behaviour when network interfaces are
614 still doing duplicate address detection (DAD). Previously,
615 dnsmasq would wait up to 20 seconds at start-up for the
616 DAD state to terminate. This is broken for bridge
617 interfaces on recent Linux kernels, which don't start DAD
618 until the bridge comes up, and so can take arbitrary
619 time. The new behaviour lets dnsmasq poll for an arbitrary
620 time whilst providing service on other interfaces. Thanks
621 to Stephen Hemminger for pointing out the problem.
625 Provide a definition of the SA_SIZE macro where it's
626 missing. Fixes build failure on openBSD.
628 Don't include a zero terminator at the end of messages
629 sent to /dev/log when /dev/log is a datagram socket.
630 Thanks to Didier Rabound for spotting the problem.
632 Add --dhcp-sequential-ip flag, to force allocation of IP
633 addresses in ascending order. Note that the default
634 pseudo-random mode is in general better but some
635 server-deployment applications need this.
637 Fix problem where a server-id of 0.0.0.0 is sent to a
638 client when a dhcp-relay is in use if a client renews a
639 lease after dnsmasq restart and before any clients on the
640 subnet get a new lease. Thanks to Mike Ruiz for assistance
641 in chasing this one down.
643 Don't return NXDOMAIN to an AAAA query if we have CNAME
644 which points to an A record only: NODATA is the correct
645 reply in this case. Thanks to Tom Fernandes for spotting
648 Relax the need to supply a netmask in --dhcp-range for
649 networks which use a DHCP relay. Whilst this is still
650 desireable, in the absence of a netmask dnsmasq will use
651 a default based on the class (A, B, or C) of the address.
652 This should at least remove a cause of mysterious failure
653 for people using RFC1918 addresses and relays.
655 Add support for Linux conntrack connection marking. If
656 enabled with --conntrack, the connection mark for incoming
657 DNS queries will be copied to the outgoing connections
658 used to answer those queries. This allows clever firewall
659 and accounting stuff. Only available if dnsmasq is
660 compiled with HAVE_CONNTRACK and adds a dependency on
661 libnetfilter-conntrack. Thanks to Ed Wildgoose for the
662 initial idea, testing and sponsorship of this function.
664 Provide a sane error message when someone attempts to
665 match a tag in --dhcp-host.
667 Tweak the behaviour of --domain-needed, to avoid problems
668 with recursive nameservers downstream of dnsmasq. The new
669 behaviour only stops A and AAAA queries, and returns
670 NODATA rather than NXDOMAIN replies.
672 Efficiency fix for very large DHCP configurations, thanks
673 to James Gartrell and Mike Ruiz for help with this.
675 Allow the TFTP-server address in --dhcp-boot to be a
676 domain-name which is looked up in /etc/hosts. This can
677 give multiple IP addresses which are used round-robin,
678 thus doing TFTP server load-balancing. Thanks to Sushil
679 Agrawal for the patch.
681 When two tagged dhcp-options for a particular option
682 number are both valid, use the one which is valid without
683 a tag from the dhcp-range. Allows overriding of the value
684 of a DHCP option for a particular host as well as
685 per-network values. So
686 --dhcp-range=set:interface1,......
687 --dhcp-host=set:myhost,.....
688 --dhcp-option=tag:interface1,option:nis-domain,"domain1"
689 --dhcp-option=tag:myhost,option:nis-domain,"domain2"
690 will set the NIS-domain to domain1 for hosts in the range, but
691 override that to domain2 for a particular host.
693 Fix bug which resulted in truncated files and timeouts for
694 some TFTP transfers. The bug only occurs with netascii
695 transfers and needs an unfortunate relationship between
696 file size, blocksize and the number of newlines in the
697 last block before it manifests itself. Many thanks to
698 Alkis Georgopoulos for spotting the problem and providing
699 a comprehensive test-case.
701 Fix regression in TFTP server on *BSD platforms introduced
702 in version 2.56, due to confusion with sockaddr
703 length. Many thanks to Loic Pefferkorn for finding this.
705 Support scope-ids in IPv6 addresses of nameservers from
706 /etc/resolv.conf and in --server options. Eg
707 nameserver fe80::202:a412:4512:7bbf%eth0 or
708 server=fe80::202:a412:4512:7bbf%eth0. Thanks to
709 Michael Stapelberg for the suggestion.
711 Update Polish translation, thanks to Jan Psota.
713 Update French translation. Thanks to Gildas Le Nadan.
717 Add patches to allow build under Android.
719 Provide our own header for the DNS protocol, rather than
720 relying on arpa/nameser.h. This has proved more or less
721 defective over the years and the final straw is that it's
722 effectively empty on Android.
724 Fix regression in 2.56 which caused hex constants in
725 configuration to be rejected if they contain the '*'
728 Correct wrong casts of arguments to ctype.h functions,
729 isdigit(), isxdigit() etc. Thanks to Matthias Andree for
732 Allow build with IDN support independently from i18n.
733 IDN support continues to be included automatically
734 when i18n is included.
735 'make COPTS=-DHAVE_IDN' is the magic incantation.
737 Modify check on extraneous command line junk (added in
738 2.56) so that it doesn't complain about extra _empty_
739 arguments. Otherwise this breaks libvirt.
743 Add a patch to allow dnsmasq to get interface names right in a
744 Solaris zone. Thanks to Dj Padzensky for this.
746 Improve data-type parsing heuristics so that
747 --dhcp-option=option:domain-search,.
748 treats the value as a string and not an IP address.
749 Thanks to Clemens Fischer for spotting that.
751 Add IPv6 support to the TFTP server. Many thanks to Jan
752 'RedBully' Seiffert for the patches.
754 Log DNS queries at level LOG_INFO, rather then
755 LOG_DEBUG. This makes things consistent with DHCP
756 logging. Thanks to Adam Pribyl for spotting the problem.
758 Ensure that dnsmasq terminates cleanly when using
759 --syslog-async even if it cannot make a connection to the
762 Add --add-mac option. This is to support currently
763 experimental DNS filtering facilities. Thanks to Benjamin
764 Petrin for the orignal patch.
766 Fix bug which meant that tags were ignored in dhcp-range
767 configuration specifying PXE-proxy service. Thanks to
768 Cristiano Cumer for spotting this.
770 Raise an error if there is extra junk, not part of an
771 option, on the command line.
773 Flag a couple of log messages in cache.c as coming from
774 the DHCP subsystem. Thanks to Olaf Westrik for the patch.
776 Omit timestamps from logs when a) logging to stderr and
777 b) --keep-in-forground is set. The logging facility on the
778 other end of stderr can be assumned to supply them. Thanks
779 to John Hallam for the patch.
781 Don't complain about strings longer than 255 characters in
782 --txt-record, just split the long strings into 255
783 character chunks instead.
785 Fix crash on double-free. This bug can only happen when
786 dhcp-script is in use and then only in rare circumstances
787 triggered by high DHCP transaction rate and a slow
788 script. Thanks to Ferenc Wagner for finding the problem.
790 Only log that a file has been sent by TFTP after the
791 transfer has completed succesfully.
793 A good suggestion from Ferenc Wagner: extend
794 the --domain option to allow this sort of thing:
795 --domain=thekelleys.org.uk,192.168.0.0/24,local
796 which automatically creates
797 --local=/thekelleys.org.uk/
798 --local=/0.168.192.in-addr.arpa/
800 Tighten up syntax checking of hex contants in the config
801 file. Thanks to Fred Damen for spotting this.
803 Add dnsmasq logo/icon, contributed by Justin Swift. Many
806 Never cache DNS replies which have the 'cd' bit set, or
807 which result from queries forwarded with the 'cd' bit
808 set. The 'cd' bit instructs a DNSSEC validating server
809 upstream to ignore signature failures and return replies
810 anyway. Without this change it's possible to pollute the
811 dnsmasq cache with bad data by making a query with the
812 'cd' bit set and subsequent queries would return this data
813 without its being marked as suspect. Thanks to Anders
814 Kaseorg for pointing out this problem.
816 Add --proxy-dnssec flag, for compliance with RFC
817 4035. Dnsmasq will now clear the 'ad' bit in answers returned
818 from upstream validating nameservers unless this option is
821 Allow a filename of "-" for --conf-file to read
822 stdin. Suggestion from Timothy Redaelli.
824 Rotate the order of SRV records in replies, to provide
825 round-robin load balancing when all the priorities are
826 equal. Thanks to Peter McKinney for the suggestion.
829 contrib/MacOSX-launchd/uk.org.thekelleys.dnsmasq.plist
830 so that it doesn't log all queries to a file by
831 default. Thanks again to Peter McKinney.
833 By default, setting an IPv4 address for a domain but not
834 an IPv6 address causes dnsmasq to return
835 an NODATA reply for IPv6 (or vice-versa). So
836 --address=/google.com/1.2.3.4 stops IPv6 queries for
837 *google.com from being forwarded. Make it possible to
838 override this behaviour by defining the sematics if the
839 same domain appears in both --server and --address.
840 In that case, the --address has priority for the address
841 family in which is appears, but the --server has priority
842 of the address family which doesn't appear in --adddress
844 --address=/google.com/1.2.3.4
845 --server=/google.com/#
846 will return 1.2.3.4 for IPv4 queries for *.google.com but
847 forward IPv6 queries to the normal upstream nameserver.
848 Similarly when setting an IPv6 address
849 only this will allow forwarding of IPv4 queries. Thanks to
850 William for pointing out the need for this.
852 Allow more than one --dhcp-optsfile and --dhcp-hostsfile
853 and make them understand directories as arguments in the
854 same way as --addn-hosts. Suggestion from John Hanks.
856 Ignore rebinding requests for leases we don't know
857 about. Rebind is broadcast, so we might get to overhear a
858 request meant for another DHCP server. NAKing this is
859 wrong. Thanks to Brad D'Hondt for assistance with this.
861 Fix cosmetic bug which produced strange output when
862 dumping cache statistics with some configurations. Thanks
863 to Fedor Kozhevnikov for spotting this.
867 Fix crash when /etc/ethers is in use. Thanks to
868 Gianluigi Tiesi for finding this.
870 Fix crash in netlink_multicast(). Thanks to Arno Wald for
873 Allow the empty domain "." in dhcp domain-search (119)
878 There is no version 2.54 to avoid confusion with 2.53,
879 which incorrectly identifies itself as 2.54.
883 Fix failure to compile on Debian/kFreeBSD. Thanks to
884 Axel Beckert and Petr Salinger.
886 Fix code to avoid scary strict-aliasing warnings
887 generated by gcc 4.4.
889 Added FAQ entry warning about DHCP failures with Vista
890 when firewalls block 255.255.255.255.
892 Fixed bug which caused bad things to happen if a
893 resolv.conf file which exists is subsequently removed.
894 Thanks to Nikolai Saoukh for the patch.
896 Rationalised the DHCP tag system. Every configuration item
897 which can set a tag does so by adding "set:<tag>" and
898 every configuration item which is conditional on a tag is
899 made so by "tag:<tag>". The NOT operator changes to '!',
900 which is a bit more intuitive too. Dhcp-host directives
901 can set more than one tag now. The old '#' NOT,
902 "net:" prefix and no-prefixes are still honoured, so
903 no existing config file needs to be changed, but
904 the documentation and new-style config files should be
907 Added --tag-if to allow boolean operations on tags.
908 This allows complicated logic to be clearer and more
909 general. A great suggestion from Richard Voigt.
911 Add broadcast/unicast information to DHCP logging.
913 Allow --dhcp-broadcast to be unconditional.
915 Fixed incorrect behaviour with NOT <tag> conditionals in
916 dhcp-options. Thanks to Max Turkewitz for assistance
919 If we send vendor-class encapsulated options based on the
920 vendor-class supplied by the client, and no explicit
921 vendor-class option is given, echo back the vendor-class
924 Fix bug which stopped dnsmasq from matching both a
925 circuitid and a remoteid. Thanks to Ignacio Bravo for
928 Add --dhcp-proxy, which makes it possible to configure
929 dnsmasq to use a DHCP relay agent as a full proxy, with
930 all DHCP messages passing through the proxy. This is
931 useful if the relay adds extra information to the packets
932 it forwards, but cannot be configured with the RFC 5107
933 server-override option.
935 Added interface:<iface name> part to dhcp-range. The
936 semantics of this are very odd at first sight, but it
937 allows a single line of the form
938 dhcp-range=interface:virt0,192.168.0.4,192.168.0.200
939 to be added to dnsmasq configuration which then supplies
940 DHCP and DNS services to that interface, without affecting
941 what services are supplied to other interfaces and
942 irrespective of the existance or lack of
943 interface=<interface>
944 lines elsewhere in the dnsmasq configuration. The idea is
945 that such a line can be added automatically by libvirt
946 or equivalent systems, without disturbing any manual
949 Similarly to the above, allow --enable-tftp=<interface>
951 Allow a TFTP root to be set separately for requests via
952 different interfaces, --tftp-root=<path>,<interface>
954 Correctly handle and log clashes between CNAMES and
955 DNS names being given to DHCP leases. This fixes a bug
956 which caused nonsense IP addresses to be logged. Thanks to
957 Sergei Zhirikov for finding and analysing the problem.
959 Tweak flush_log so as to avoid leaving the log
960 file in non-blocking mode. O_NONBLOCK is a property of the
961 file, not the process/descriptor.
963 Fix contrib/Solaris10/create_package
964 (/usr/man -> /usr/share/man) Thanks to Vita Batrla.
966 Fix a problem where, if a client got a lease, then went
967 to another subnet and got another lease, then moved back,
968 it couldn't resume the old lease, but would instead get
969 a new address. Thanks to Leonardo Rodrigues for spotting
970 this and testing the fix.
972 Fix weird bug which sometimes omitted certain characters
973 from the start of quoted strings in dhcp-options. Thanks
974 to Dayton Turner for spotting the problem.
976 Add facility to redirect some domains to the standard
977 upstream servers: this allows something like
978 --server=/google.com/1.2.3.4 --server=/www.google.com/#
979 which will send queries for *.google.com to 1.2.3.4,
980 except *www.google.com which will be forwarded as usual.
981 Thanks to AJ Weber for prompting this addition.
983 Improve the hash-algorithm used to generate IP addresses
984 from MAC addresses during initial DHCP address
985 allocation. This improves performance when large numbers
986 of hosts with similar MAC addresses all try and get an IP
987 address at the same time. Thanks to Paul Smith for his
990 Tweak DHCP code so that --bridge-interface can be used to
991 select which IP alias of an interface should be used for
992 DHCP purposes on Linux. If eth0 has an alias eth0:dhcp
993 then adding --bridge-interface=eth0:dhcp,eth0 will use
994 the address of eth0:dhcp to determine the correct subnet
995 for DHCP address allocation. Thanks to Pawel Golaszewski
996 for prompting this and Eric Cooper for further testing.
998 Add --dhcp-generate-names. Suggestion by Ferenc Wagner.
1000 Tweak DNS server selection algorithm when there is more
1001 than one server available for a domain, eg.
1002 --server=/mydomain/1.1.1.1
1003 --server=/mydomain/2.2.2.2
1004 Thanks to Alberto Cuesta-Canada for spotting a weakness
1007 Add --max-ttl. Thanks to Fredrik Ringertz for the patch.
1009 Allow --log-facility=- to force all logging to
1010 stderr. Suggestion from Clemens Fischer.
1012 Fix regression which caused configuration like
1013 --address=/.domain.com/1.2.3.4 to be rejected. The dot to the
1014 left of the domain has been implied and not required for a
1015 long time, but it should be accepted for backward
1016 compatibility. Thanks to Andrew Burcin for spotting this.
1018 Add --rebind-domain-ok and --rebind-localhost-ok.
1019 Suggestion from Clemens Fischer.
1021 Log replies to queries of type TXT, when --log-queries
1024 Fix compiler warnings when compiled with -DNO_DHCP. Thanks
1025 to Shantanu Gadgil for the patch.
1027 Updated French translation. Thanks to Gildas Le Nadan.
1029 Updated Polish translation. Thanks to Jan Psota.
1031 Updated German translation. Thanks to Matthias Andree.
1033 Added contrib/static-arp, thanks to Darren Hoo.
1035 Fix corruption of the domain when a name from /etc/hosts
1036 overrides one supplied by a DHCP client. Thanks to Fedor
1037 Kozhevnikov for spotting the problem.
1039 Updated Spanish translation. Thanks to Chris Chatham.
1043 Work around a Linux kernel bug which insists that the
1044 length of the option passed to setsockopt must be at least
1045 sizeof(int) bytes, even if we're calling SO_BINDTODEVICE
1046 and the device name is "lo". Note that this is fixed
1047 in kernel 2.6.31, but the workaround is harmless and
1048 allows earlier kernels to be used. Also fix dnsmasq
1049 bug which reported the wrong address when this failed.
1050 Thanks to Fedor for finding this.
1052 The API for IPv6 PKTINFO changed around Linux kernel
1053 2.6.14. Workaround the case where dnsmasq is compiled
1054 against newer headers, but then run on an old kernel:
1055 necessary for some *WRT distros.
1057 Re-read the set of network interfaces when re-loading
1058 /etc/resolv.conf if --bind-interfaces is not set. This
1059 handles the case that loopback interfaces do not exist
1060 when dnsmasq is first started.
1062 Tweak the PXE code to support port 4011. This should
1063 reduce broadcasts and make things more reliable when other
1064 servers are around. It also improves inter-operability
1065 with certain clients.
1067 Make a pxe-service configuration with no filename or boot
1068 service type legal: this does a local boot. eg.
1069 pxe-service=x86PC, "Local boot"
1071 Be more conservative in detecting "A for A"
1072 queries. Dnsmasq checks if the name in a type=A query looks
1073 like a dotted-quad IP address and answers the query itself
1074 if so, rather than forwarding it. Previously dnsmasq
1075 relied in the library function inet_addr() to convert
1076 addresses, and that will accept some things which are
1077 confusing in this context, like 1.2.3 or even just
1078 1234. Now we only do A for A processing for four decimal
1079 numbers delimited by dots.
1081 A couple of tweaks to fix compilation on Solaris. Thanks
1082 to Joel Macklow for help with this.
1084 Another Solaris compilation tweak, needed for Solaris
1085 2009.06. Thanks to Lee Essen for that.
1087 Added extract packaging stuff from Lee Essen to
1090 Increased the default limit on number of leases to 1000
1091 (from 150). This is mainly a defence against DoS attacks,
1092 and for the average "one for two class C networks"
1093 installation, IP address exhaustion does that just as
1094 well. Making the limit greater than the number of IP
1095 addresses available in such an installation removes a
1096 surprise which otherwise can catch people out.
1098 Removed extraneous trailing space in the value of the
1099 DNSMASQ_TIME_REMAINING DNSMASQ_LEASE_LENGTH and
1100 DNSMASQ_LEASE_EXPIRES environment variables. Thanks to
1101 Gildas Le Nadan for spotting this.
1103 Provide the network-id tags for a DHCP transaction to
1104 the lease-change script in the environment variable
1105 DNSMASQ_TAGS. A good suggestion from Gildas Le Nadan.
1107 Add support for RFC3925 "Vendor-Identifying Vendor
1108 Options". The syntax looks like this:
1109 --dhcp-option=vi-encap:<enterprise number>, .........
1111 Add support to --dhcp-match to allow matching against
1112 RFC3925 "Vendor-Identifying Vendor Classes". The syntax
1114 --dhcp-match=tag,vi-encap<enterprise number>, <value>
1116 Add some application specific code to assist in
1117 implementing the Broadband forum TR069 CPE-WAN
1118 specification. The details are in contrib/CPE-WAN/README
1120 Increase the default DNS packet size limit to 4096, as
1121 recommended by RFC5625 section 4.4.3. This can be
1122 reconfigured using --edns-packet-max if needed. Thanks to
1123 Francis Dupont for pointing this out.
1125 Rewrite query-ids even for TSIG signed packets, since
1126 this is allowed by RFC5625 section 4.5.
1128 Use getopt_long by default on OS X. It has been supported
1129 since version 10.3.0. Thanks to Arek Dreyer for spotting
1132 Added up-to-date startup configuration for MacOSX/launchd
1133 in contrib/MacOSX-launchd. Thanks to Arek Dreyer for
1136 Fix link error when including Dbus but excluding DHCP.
1137 Thanks to Oschtan for the bug report.
1139 Updated French translation. Thanks to Gildas Le Nadan.
1141 Updated Polish translation. Thanks to Jan Psota.
1143 Updated Spanish translation. Thanks to Chris Chatham.
1145 Fixed confusion about domains, when looking up DHCP hosts
1146 in /etc/hosts. This could cause spurious "Ignoring
1147 domain..." messages. Thanks to Fedor Kozhevnikov for
1148 finding and analysing the problem.
1152 Add support for internationalised DNS. Non-ASCII characters
1153 in domain names found in /etc/hosts, /etc/ethers and
1154 /etc/dnsmasq.conf will be correctly handled by translation to
1155 punycode, as specified in RFC3490. This function is only
1156 available if dnsmasq is compiled with internationalisation
1157 support, and adds a dependency on GNU libidn. Without i18n
1158 support, dnsmasq continues to be compilable with just
1159 standard tools. Thanks to Yves Dorfsman for the
1162 Add two more environment variables for lease-change scripts:
1163 First, DNSMASQ_SUPPLIED_HOSTNAME; this is set to the hostname
1164 supplied by a client, even if the actual hostname used is
1165 over-ridden by dhcp-host or dhcp-ignore-names directives.
1166 Also DNSMASQ_RELAY_ADDRESS which gives the address of
1167 a DHCP relay, if used.
1168 Suggestions from Michael Rack.
1170 Fix regression which broke echo of relay-agent
1171 options. Thanks to Michael Rack for spotting this.
1173 Don't treat option 67 as being interchangeable with
1174 dhcp-boot parameters if it's specified as
1177 Make the code to call scripts on lease-change compile-time
1178 optional. It can be switched off by editing src/config.h
1179 or building with "make COPTS=-DNO_SCRIPT".
1181 Make the TFTP server cope with filenames from Windows/DOS
1182 which use '\' as pathname separator. Thanks to Ralf for
1185 Updated Polish translation. Thanks to Jan Psota.
1187 Warn if an IP address is duplicated in /etc/ethers. Thanks
1188 to Felix Schwarz for pointing this out.
1190 Teach --conf-dir to take an option list of file suffices
1191 which will be ignored when scanning the directory. Useful
1192 for backup files etc. Thanks to Helmut Hullen for the
1195 Add new DHCP option named tftpserver-address, which
1196 corresponds to the third argument of dhcp-boot. This
1197 allows the complete functionality of dhcp-boot to be
1198 replicated with dhcp-option. Useful when using
1201 Test which upstream nameserver to use every 10 seconds
1202 or 50 queries and not just when a query times out and
1203 is retried. This should improve performance when there
1204 is a slow nameserver in the list. Thanks to Joe for the
1207 Don't do any PXE processing, even for clients with the
1208 correct vendorclass, unless at least one pxe-prompt or
1209 pxe-service option is given. This stops dnsmasq
1210 interfering with proxy PXE subsystems when it is just
1211 the DHCP server. Thanks to Spencer Clark for spotting this.
1213 Limit the blocksize used for TFTP transfers to a value
1214 which avoids packet fragmentation, based on the MTU of the
1215 local interface. Many netboot ROMs can't cope with
1218 Honour dhcp-ignore configuration for PXE and proxy-PXE
1219 requests. Thanks to Niels Basjes for the bug report.
1221 Updated French translation. Thanks to Gildas Le Nadan.
1225 Fix security problem which allowed any host permitted to
1226 do TFTP to possibly compromise dnsmasq by remote buffer
1227 overflow when TFTP enabled. Thanks to Core Security
1228 Technologies and Iván Arce, Pablo Hernán Jorge, Alejandro
1229 Pablo Rodriguez, Martín Coco, Alberto Soliño Testa and
1230 Pablo Annetta. This problem has Bugtraq id: 36121
1233 Fix a problem which allowed a malicious TFTP client to
1234 crash dnsmasq. Thanks to Steve Grubb at Red Hat for
1235 spotting this. This problem has Bugtraq id: 36120 and
1240 Fix regression in 2.48 which disables the lease-change
1241 script. Thanks to Jose Luis Duran for spotting this.
1243 Log TFTP "file not found" errors. These were not logged,
1244 since a normal PXELinux boot generates many of them, but
1245 the lack of the messages seems to be more confusing than
1246 routinely seeing them when there is no real error.
1248 Update Spanish translation. Thanks to Chris Chatham.
1252 Archived the extensive, backwards, changelog to
1253 CHANGELOG.archive. The current changelog now runs from
1254 version 2.43 and runs conventionally.
1256 Fixed bug which broke binding of servers to physical
1257 interfaces when interface names were longer than four
1258 characters. Thanks to MURASE Katsunori for the patch.
1260 Fixed netlink code to check that messages come from the
1261 correct source, and not another userspace process. Thanks
1262 to Steve Grubb for the patch.
1264 Maintainability drive: removed bug and missing feature
1265 workarounds for some old platforms. Solaris 9, OpenBSD
1266 older than 4.1, Glibc older than 2.2, Linux 2.2.x and
1267 DBus older than 1.1.x are no longer supported.
1269 Don't read included configuration files more than once:
1270 allows complex configuration structures without problems.
1272 Mark log messages from the various subsystems in dnsmasq:
1273 messages from the DHCP subsystem now have the ident string
1274 "dnsmasq-dhcp" and messages from TFTP have ident
1275 "dnsmasq-tftp". Thanks to Olaf Westrik for the patch.
1277 Fix possible infinite DHCP protocol loop when an IP
1278 address nailed to a hostname (not a MAC address) and a
1279 host sometimes provides the name, sometimes not.
1281 Allow --addn-hosts to take a directory: all the files
1282 in the directory are read. Thanks to Phil Cornelius for
1285 Support --bridge-interface on all platforms, not just BSD.
1287 Added support for advanced PXE functions. It's now
1288 possible to define a prompt and menu options which will
1289 be displayed when a client PXE boots. It's also possible to
1290 hand-off booting to other boot servers. Proxy-DHCP, where
1291 dnsmasq just supplies the PXE information and another DHCP
1292 server does address allocation, is also allowed. See the
1293 --pxe-prompt and --pxe-service keywords. Thanks to
1294 Alkis Georgopoulos for the suggestion and Guilherme Moro
1295 and Michael Brown for assistance.
1297 Improvements to DHCP logging. Thanks to Tom Metro for
1300 Add ability to build dnsmasq without DHCP support. To do
1301 this, edit src/config.h or build with
1302 "make COPTS=-DNO_DHCP". Thanks to Mahavir Jain for the patch.
1304 Added --test command-line switch - syntax check
1305 configuration files only.
1307 Updated French translation. Thanks to Gildas Le Nadan.
1311 Updated French translation. Thanks to Gildas Le Nadan.
1313 Fixed interface enumeration code to work on NetBSD
1314 5.0. Thanks to Roy Marples for the patch.
1316 Updated config.h to use the same location for the lease
1317 file on NetBSD as the other *BSD variants. Also allow
1318 LEASEFILE and CONFFILE symbols to be overriden in CFLAGS.
1320 Handle duplicate address detection on IPv6 more
1321 intelligently. In IPv6, an interface can have an address
1322 which is not usable, because it is still undergoing DAD
1323 (such addresses are marked "tentative"). Attempting to
1324 bind to an address in this state returns an error,
1325 EADDRNOTAVAIL. Previously, on getting such an error,
1326 dnsmasq would silently abandon the address, and never
1327 listen on it. Now, it retries once per second for 20
1328 seconds before generating a fatal error. 20 seconds should
1329 be long enough for any DAD process to complete, but can be
1330 adjusted in src/config.h if necessary. Thanks to Martin
1331 Krafft for the bug report.
1333 Add DBus introspection. Patch from Jeremy Laine.
1335 Update Dbus configuration file. Patch from Colin Walters.
1337 http://bugs.freedesktop.org/show_bug.cgi?id=18961
1339 Support arbitrarily encapsulated DHCP options, suggestion
1340 and initial patch from Samium Gromoff. This is useful for
1341 (eg) gPXE, which expect all its private options to be
1342 encapsulated inside a single option 175. So, eg,
1344 dhcp-option = encap:175, 190, "iscsi-client0"
1345 dhcp-option = encap:175, 191, "iscsi-client0-secret"
1347 will provide iSCSI parameters to gPXE.
1349 Enhance --dhcp-match to allow testing of the contents of a
1350 client-sent option, as well as its presence. This
1351 application in mind for this is RFC 4578
1352 client-architecture specifiers, but it's generally useful.
1353 Joey Korkames suggested the enhancement.
1355 Move from using the IP_XMIT_IF ioctl to IP_BOUND_IF on
1356 OpenSolaris. Thanks to Bastian Machek for the heads-up.
1358 No longer complain about blank lines in
1359 /etc/ethers. Thanks to Jon Nelson for the patch.
1361 Fix binding of servers to physical devices, eg
1362 --server=/domain/1.2.3.4@eth0 which was broken from 2.43
1363 onwards unless --query-port=0 set. Thanks to Peter Naulls
1366 Reply to DHCPINFORM requests even when the supplied ciaddr
1367 doesn't fall in any dhcp-range. In this case it's not
1368 possible to supply a complete configuration, but
1369 individually-configured options (eg PAC) may be useful.
1371 Allow the source address of an alias to be a range:
1372 --alias=192.168.0.0,10.0.0.0,255.255.255.0 maps the whole
1373 subnet 192.168.0.0->192.168.0.255 to 10.0.0.0->10.0.0.255,
1375 --alias=192.168.0.10-192.168.0.40,10.0.0.0,255.255.255.0
1376 maps only the 192.168.0.10->192.168.0.40 region. Thanks to
1377 Ib Uhrskov for the suggestion.
1379 Don't dynamically allocate DHCP addresses which may break
1380 Windows. Addresses which end in .255 or .0 are broken in
1381 Windows even when using supernetting.
1382 --dhcp-range=192.168.0.1,192.168.1.254,255,255,254.0 means
1383 192.168.0.255 is a valid IP address, but not for Windows.
1384 See Microsoft KB281579. We therefore no longer allocate
1385 these addresses to avoid hard-to-diagnose problems.
1387 Update Polish translation. Thanks to Jan Psota.
1389 Delete the PID-file when dnsmasq shuts down. Note that by
1390 this time, dnsmasq is normally not running as root, so
1391 this will fail if the PID-file is stored in a root-owned
1392 directory; such failure is silently ignored. To take
1393 advantage of this feature, the PID-file must be stored in a
1394 directory owned and write-able by the user running
1399 Allow --bootp-dynamic to take a netid tag, so that it may
1400 be selectively enabled. Thanks to Olaf Westrik for the
1403 Remove ISC-leasefile reading code. This has been
1404 deprecated for a long time, and last time I removed it, it
1405 ended up going back by request of one user. This time,
1406 it's gone for good; otherwise it would need to be
1407 re-worked to support multiple domains (see below).
1409 Support DHCP clients in multiple DNS domains. This is a
1410 long-standing request. Clients are assigned to a domain
1411 based in their IP address.
1413 Add --dhcp-fqdn flag, which changes behaviour if DNS names
1414 assigned to DHCP clients. When this is set, there must be
1415 a domain associated with each client, and only
1416 fully-qualified domain names are added to the DNS. The
1417 advantage is that the only the FQDN needs to be unique,
1418 so that two or more DHCP clients can share a hostname, as
1419 long as they are in different domains.
1421 Set environment variable DNSMASQ_DOMAIN when invoking
1422 lease-change script. This may be useful information to
1423 have now that it's variable.
1425 Tighten up data-checking code for DNS packet
1426 handling. Thanks to Steve Dodd who found certain illegal
1427 packets which could crash dnsmasq. No memory overwrite was
1428 possible, so this is not a security issue beyond the DoS
1431 Update example config dhcp option 47, the previous
1432 suggestion generated an illegal, zero-length,
1433 option. Thanks to Matthias Andree for finding this.
1435 Rewrite hosts-file reading code to remove the limit of
1436 1024 characters per line. John C Meuser found this.
1438 Create a net-id tag with the name of the interface on
1439 which the DHCP request was received.
1441 Fixed minor memory leak in DBus code, thanks to Jeremy
1442 Laine for the patch.
1444 Emit DBus signals as the DHCP lease database
1445 changes. Thanks to Jeremy Laine for the patch.
1447 Allow for more that one MAC address in a dhcp-host
1448 line. This configuration tells dnsmasq that it's OK to
1449 abandon a DHCP lease of the fixed address to one MAC
1450 address, if another MAC address in the dhcp-host statement
1451 asks for an address. This is useful to give a fixed
1452 address to a host which has two network interfaces
1453 (say, a laptop with wired and wireless interfaces.)
1454 It's very important to ensure that only one interface
1455 at a time is up, since dnsmasq abandons the first lease
1456 and re-uses the address before the leased time has
1457 elapsed. John Gray suggested this.
1459 Tweak the response to a DHCP request packet with a wrong
1460 server-id when --dhcp-authoritative is set; dnsmasq now
1461 returns a DHCPNAK, rather than silently ignoring the
1462 packet. Thanks to Chris Marget for spotting this
1465 Add --cname option. This provides a limited alias
1466 function, usable for DHCP names. Thanks to AJ Weber for
1467 suggestions on this.
1469 Updated contrib/webmin with latest version from Neil
1472 Updated Polish translation. Thanks to Jan Psota.
1474 Correct the text names for DHCP options 64 and 65 to be
1475 "nis+-domain" and "nis+-servers".
1477 Updated Spanish translation. Thanks to Chris Chatham.
1479 Force re-reading of /etc/resolv.conf when an "interface
1484 Fix total DNS failure in release 2.44 unless --min-port
1485 specified. Thanks to Steven Barth and Grant Coady for
1486 bugreport. Also reject out-of-range port spec, which could
1487 break things too: suggestion from Gilles Espinasse.
1491 Fix crash when unknown client attempts to renew a DHCP
1492 lease, problem introduced in version 2.43. Thanks to
1493 Carlos Carvalho for help chasing this down.
1495 Fix potential crash when a host which doesn't have a lease
1496 does DHCPINFORM. Again introduced in 2.43. This bug has
1497 never been reported in the wild.
1499 Fix crash in netlink code introduced in 2.43. Thanks to
1500 Jean Wolter for finding this.
1502 Change implementation of min_port to work even if min-port
1505 Patch to enable compilation of latest Mac OS X. Thanks to
1508 Update Spanish translation. Thanks to Christopher Chatham.
1512 Updated Polish translation. Thanks to Jan Psota.
1514 Flag errors when configuration options are repeated
1517 Further tweaks for GNU/kFreeBSD
1519 Add --no-wrap to msgmerge call - provides nicer .po file
1522 Honour lease-time spec in dhcp-host lines even for
1523 BOOTP. The user is assumed to known what they are doing in
1524 this case. (Hosts without the time spec still get infinite
1525 leases for BOOTP, over-riding the default in the
1526 dhcp-range.) Thanks to Peter Katzmann for uncovering this.
1528 Fix problem matching relay-agent ids. Thanks to Michael
1529 Rack for the bug report.
1531 Add --naptr-record option. Suggestion from Johan
1534 Implement RFC 5107 server-id-override DHCP relay agent
1537 Apply patches from Stefan Kruger for compilation on
1538 Solaris 10 under Sun studio.
1540 Yet more tweaking of Linux capability code, to suppress
1541 pointless wingeing from kernel 2.6.25 and above.
1543 Improve error checking during startup. Previously, some
1544 errors which occurred during startup would be worked
1545 around, with dnsmasq still starting up. Some were logged,
1546 some silent. Now, they all cause a fatal error and dnsmasq
1547 terminates with a non-zero exit code. The errors are those
1548 associated with changing uid and gid, setting process
1549 capabilities and writing the pidfile. Thanks to Uwe
1550 Gansert and the Suse security team for pointing out
1551 this improvement, and Bill Reimers for good implementation
1554 Provide NO_LARGEFILE compile option to switch off largefile
1555 support when compiling against versions of uclibc which
1556 don't support it. Thanks to Stephane Billiart for the patch.
1558 Implement random source ports for interactions with
1559 upstream nameservers. New spoofing attacks have been found
1560 against nameservers which do not do this, though it is not
1561 clear if dnsmasq is vulnerable, since to doesn't implement
1562 recursion. By default dnsmasq will now use a different
1563 source port (and socket) for each query it sends
1564 upstream. This behaviour can suppressed using the
1565 --query-port option, and the old default behaviour
1566 restored using --query-port=0. Explicit source-port
1567 specifications in --server configs are still honoured.
1569 Replace the random number generator, for better
1570 security. On most BSD systems, dnsmasq uses the
1571 arc4random() RNG, which is secure, but on other platforms,
1572 it relied on the C-library RNG, which may be
1573 guessable and therefore allow spoofing. This release
1574 replaces the libc RNG with the SURF RNG, from Daniel
1575 J. Berstein's DJBDNS package.
1577 Don't attempt to change user or group or set capabilities
1578 if dnsmasq is run as a non-root user. Without this, the
1579 change from soft to hard errors when these fail causes
1580 problems for non-root daemons listening on high
1581 ports. Thanks to Patrick McLean for spotting this.
1583 Updated French translation. Thanks to Gildas Le Nadan.
1587 The changelog for version 2.42 and earlier is
1588 available in CHANGELOG.archive.
