2 Fix crash if upstream server returns SERVFAIL when
3 --conntrack in use. Thanks to Giacomo Tazzari for finding
4 this and supplying the patch.
6 Repair regression in 2.64. That release stopped sending
7 lease-time information in the reply to DHCPINFORM
8 requests, on the correct grounds that it was a standards
9 violation. However, this broke the dnsmasq-specific
10 dhcp_lease_time utility. Now, DHCPINFORM returns
11 lease-time only if it's specifically requested
12 (maintaining standards) and the dhcp_lease_time utility
13 has been taught to ask for it (restoring functionality).
15 Fix --dhcp-match, --dhcp-vendorclass and --dhcp-userclass
16 to work with BOOTP and well as DHCP. Thanks to Peter
17 Korsgaard for spotting the problem.
19 Add --synth-domain. Thanks to Vishvananda Ishaya for
22 Fix failure to compile ipset.c if old kernel headers are
23 in use. Thanks to Eugene Rudoy for pointing this out.
25 Handle IPv4 interface-address labels in Linux. These are
26 often used to emulate the old IP-alias addresses. Before,
27 using --interface=eth0 would service all the addresses of
28 eth0, including ones configured as aliases, which appear
29 in ifconfig as eth0:0. Now, only addresses with the label
30 eth0 are active. This is not backwards compatible: if you
31 want to continue to bind the aliases too, you need to add
32 eg. --interface=eth0:0 to the config.
34 Fix "failed to set SO_BINDTODEVICE on DHCP socket: Socket
35 operation on non-socket" error on startup with
36 configurations which have exactly one --interface option
37 and do RA but _not_ DHCPv6. Thanks to Trever Adams for the
40 Generalise --interface-name to cope with IPv6 addresses
41 and multiple addresses per interface per address family.
43 Fix option parsing for --dhcp-host, which was generating a
44 spurious error when all seven possible items were
45 included. Thanks to Zhiqiang Wang for the bug report.
47 Remove restriction on prefix-length in --auth-zone. Thanks
48 to Toke Hoiland-Jorgensen for suggesting this.
50 Log when the maximum number of concurrent DNS queries is
51 reached. Thanks to Marcelo Salhab Brogliato for the patch.
53 If wildcards are used in --interface, don't assume that
54 there will only ever be one available interface for DHCP
55 just because there is one at start-up. More may appear, so
56 we can't use SO_BINDTODEVICE. Thanks to Natrio for the bug
59 Increase timeout/number of retries in TFTP to accomodate
60 AudioCodes Voice Gateways doing streaming writes to flash.
61 Thanks to Damian Kaczkowski for spotting the problem.
63 Fix crash with empty DHCP string options when adding zero
64 terminator. Thanks to Patrick McLean for the bug report.
66 Allow hostnames to start with a number, as allowed in
67 RFC-1123. Thanks to Kyle Mestery for the patch.
69 Fixes to DHCP FQDN option handling: don't terminate FQDN
70 if domain not known and allow a FQDN option with blank
71 name to request that a FQDN option is returned in the
72 reply. Thanks to Roy Marples for the patch.
74 Make --clear-on-reload apply to setting upstream servers
77 When the address which triggered the construction of an
78 advertised IPv6 prefix disappears, continue to advertise
79 the prefix for up to 2 hours, with the preferred lifetime
80 set to zero. This satisfies RFC 6204 4.3 L-13 and makes
81 things work better if a prefix disappears without being
82 deprecated first. Thanks to Uwe Schindler for persuasively
85 Fix MAC address enumeration on *BSD. Thanks to Brad Smith
88 Support RFC-4242 information-refresh-time options in the
89 reply to DHCPv6 information-request. The lease time of the
90 smallest valid dhcp-range is sent. Thanks to Uwe Schindler
93 Add --force-fast-ra option. Another thanks to Uwe Schindler.
95 Make --listen-address higher priority than --except-interface
96 in all circumstances. Thanks to Thomas Hood for the bugreport.
98 Provide independent control over which interfaces get TFTP
99 service. If enable-tftp is given a list of interfaces, then TFTP
100 is provided on those. Without the list, the previous behaviour
101 (provide TFTP to the same interfaces we provide DHCP to)
102 is retained. Thanks to Lonnie Abelbeck for the suggestion.
104 Add --dhcp-relay config option.
106 Fix crash with empty tag: in --dhcp-range. Thanks to
107 Kaspar Schleiser for the bug report.
111 Add the ability to act as an authoritative DNS
112 server. Dnsmasq can now answer queries from the wider 'net
113 with local data, as long as the correct NS records are set
114 up. Only local data is provided, to avoid creating an open
115 DNS relay. Zone transfer is supported, to allow secondary
116 servers to be configured.
118 Add "constructed DHCP ranges" for DHCPv6. This is intended
119 for IPv6 routers which get prefixes dynamically via prefix
120 delegation. With suitable configuration, stateful DHCPv6
121 and RA can happen automatically as prefixes are delegated
122 and then deprecated, without having to re-write the
123 dnsmasq configuration file or restart the daemon. Thanks to
124 Steven Barth for extensive testing and development work on
127 Fix crash on startup on Solaris 11. Regression probably
128 introduced in 2.61. Thanks to Geoff Johnstone for the
131 Add code to make behaviour for TCP DNS requests that same
132 as for UDP requests, when a request arrives for an allowed
133 address, but via a banned interface. This change is only
134 active on Linux, since the relevant API is missing (AFAIK)
135 on other platforms. Many thanks to Tomas Hozza for
136 spotting the problem, and doing invaluable discovery of
137 the obscure and undocumented API required for the solution.
139 Don't send the default DHCP option advertising dnsmasq as
140 the local DNS server if dnsmasq is configured to not act
141 as DNS server, or it's configured to a non-standard port.
143 Add DNSMASQ_CIRCUIT_ID, DNSMASQ_SUBCRIBER_ID,
144 DNSMASQ_REMOTE_ID variables to the environment of the
145 lease-change script (and the corresponding Lua). These hold
146 information inserted into the DHCP request by a DHCP relay
147 agent. Thanks to Lakefield Communications for providing a
148 bounty for this addition.
150 Fixed crash, introduced in 2.64, whilst handling DHCPv6
151 information-requests with some common configurations.
152 Thanks to Robert M. Albrecht for the bug report and
155 Add --ipset option. Thanks to Jason A. Donenfeld for the
158 Don't erroneously reject some option names in --dhcp-match
159 options. Thanks to Benedikt Hochstrasser for the bug report.
161 Allow a trailing '*' wildcard in all interface-name
162 configurations. Thanks to Christian Parpart for the patch.
164 Handle the situation where libc headers define
165 SO_REUSEPORT, but the kernel in use doesn't, to cope with
166 the introduction of this option to Linux. Thanks to Rich
167 Felker for the bug report.
169 Update Polish translation. Thanks to Jan Psota.
171 Fix crash if the configured DHCP lease limit is
172 reached. Regression occurred in 2.61. Thanks to Tsachi for
175 Update the French translation. Thanks to Gildas le Nadan.
179 Fix regression which broke forwarding of queries sent via
180 TCP which are not for A and AAAA and which were directed to
181 non-default servers. Thanks to Niax for the bug report.
183 Fix failure to build with DHCP support excluded. Thanks to
184 Gustavo Zacarias for the patch.
186 Fix nasty regression in 2.64 which completely broke cacheing.
190 Handle DHCP FQDN options with all flag bits zero and
191 --dhcp-client-update set. Thanks to Bernd Krumbroeck for
192 spotting the problem.
194 Finesse the check for /etc/hosts names which conflict with
195 DHCP names. Previously a name/address pair in /etc/hosts
196 which didn't match the name/address of a DHCP lease would
197 generate a warning. Now that only happesn if there is not
198 also a match. This allows multiple addresses for a name in
199 /etc/hosts with one of them assigned via DHCP.
201 Fix broken vendor-option processing for BOOTP. Thanks to
202 Hans-Joachim Baader for the bug report.
204 Don't report spurious netlink errors, regression in
205 2.63. Thanks to Vladislav Grishenko for the patch.
207 Flag DHCP or DHCPv6 in starup logging. Thanks to
208 Vladislav Grishenko for the patch.
210 Add SetServersEx method in DBus interface. Thanks to Dan
211 Williams for the patch.
213 Add SetDomainServers method in DBus interface. Thanks to
214 Roy Marples for the patch.
216 Fix build with later Lua libraries. Thansk to Cristian
217 Rodriguez for the patch.
219 Add --max-cache-ttl option. Thanks to Dennis Kaarsemaker
222 Fix breakage of --host-record parsing, resulting in
223 infinte loop at startup. Regression in 2.63. Thanks to
224 Haim Gelfenbeyn for spotting this.
226 Set SO_REUSEADDRESS and SO_V6ONLY options on the DHCPv6
227 socket, this allows multiple instances of dnsmasq on a
228 single machine, in the same way as for DHCPv4. Thanks to
229 Gene Czarcinski and Vladislav Grishenko for work on this.
231 Fix DHCPv6 to do access control correctly when it's
232 configured with --listen-address. Thanks to
233 Gene Czarcinski for sorting this out.
235 Add a "wildcard" dhcp-range which works for any IPv6
236 subnet, --dhcp-range=::,static Useful for Stateless
237 DHCPv6. Thanks to Vladislav Grishenko for the patch.
239 Don't include lease-time in DHCPACK replies to DHCPINFORM
240 queries, since RFC-2131 says we shouldn't. Thanks to
241 Wouter Ibens for pointing this out.
243 Makefile tweak to do dependency checking on header files.
244 Thanks to Johan Peeters for the patch.
246 Check interface for outgoing unsolicited router
247 advertisements, rather than relying on interface address
248 configuration. Thanks to Gene Czarinski for the patch.
250 Handle better attempts to transmit on interfaces which are
251 still doing DAD, and specifically do not just transmit
252 without setting source address and interface, since this
253 can cause very puzzling effects when a router
254 advertisement goes astray. Thanks again to Gene Czarinski.
256 Get RA timers right when there is more than one
257 dhcp-range on a subnet.
261 Do duplicate dhcp-host address check in --test mode.
263 Check that tftp-root directories are accessible before
264 start-up. Thanks to Daniel Veillard for the initial patch.
266 Allow more than one --tfp-root flag. The per-interface
267 stuff is pointless without that.
269 Add --bind-dynamic. A hybrid mode between the default and
270 --bind-interfaces which copes with dynamically created
273 A couple of fixes to the build system for Android. Thanks
274 to Metin Kaya for the patches.
276 Remove the interface:<interface> argument in --dhcp-range, and
277 the interface argument to --enable-tftp. These were a
278 still-born attempt to allow automatic isolated
279 configuration by libvirt, but have never (to my knowledge)
280 been used, had very strange semantics, and have been
281 superceded by other mechanisms.
283 Fixed bug logging filenames when duplicate dhcp-host
284 addresses are found. Thanks to John Hanks for the patch.
286 Fix regression in 2.61 which broke caching of CNAME
287 chains. Thanks to Atul Gupta for the bug report.
289 Allow the target of a --cname flag to be another --cname.
291 Teach DHCPv6 about the RFC 4242 information-refresh-time
292 option, and add parsing if the minutes, hours and days
293 format for options. Thanks to Francois-Xavier Le Bail for
296 Allow "w" (for week) as multiplier in lease times, as well
297 as seconds, minutes, hours and days. Álvaro Gámez Machado
298 spotted the ommission.
300 Update French translation. Thanks to Gildas Le Nadan.
302 Allow a DBus service name to be given with --enable-dbus
303 which overrides the default,
304 uk.org.thekelleys.dnsmasq. Thanks to Mathieu
305 Trudel-Lapierre for the patch.
307 Set the "prefix on-link" bit in Router
308 Advertisements. Thanks to Gui Iribarren for the patch.
312 Update German translation. Thanks to Conrad Kostecki.
314 Cope with router-solict packets wich don't have a valid
315 source address. Thanks to Vladislav Grishenko for the patch.
317 Fixed bug which caused missing periodic router
318 advertisements with some configurations. Thanks to
319 Vladislav Grishenko for the patch.
321 Fixed bug which broke DHCPv6/RA with prefix lengths
322 which are not divisible by 8. Thanks to Andre Coetzee
325 Fix non-response to router-solicitations when
326 router-advertisement configured, but DHCPv6 not
327 configured. Thanks to Marien Zwart for the patch.
329 Add --dns-rr, to allow arbitrary DNS resource records.
331 Fixed bug which broke RA scheduling when an interface had
332 two addresses in the same network. Thanks to Jim Bos for
333 his help nailing this.
336 Re-write interface discovery code on *BSD to use
337 getifaddrs. This is more portable, more straightforward,
338 and allows us to find the prefix length for IPv6
341 Add ra-names, ra-stateless and slaac keywords for DHCPv6.
342 Dnsmasq can now synthesise AAAA records for dual-stack
343 hosts which get IPv6 addresses via SLAAC. It is also now
344 possible to use SLAAC and stateless DHCPv6, and to
345 tell clients to use SLAAC addresses as well as DHCP ones.
346 Thanks to Dave Taht for help with this.
348 Add --dhcp-duid to allow DUID-EN uids to be used.
350 Explicity send DHCPv6 replies to the correct port, instead
351 of relying on clients to send requests with the correct
352 source address, since at least one client in the wild gets
353 this wrong. Thanks to Conrad Kostecki for help tracking
356 Send a preference value of 255 in DHCPv6 replies when
357 --dhcp-authoritative is in effect. This tells clients not
358 to wait around for other DHCP servers.
360 Better logging of DHCPv6 options.
362 Add --host-record. Thanks to Rob Zwissler for the
365 Invoke the DHCP script with action "tftp" when a TFTP file
366 transfer completes. The size of the file, address to which
367 it was sent and complete pathname are supplied. Note that
368 version 2.60 introduced some script incompatibilties
369 associated with DHCPv6, and this is a further change. To
370 be safe, scripts should ignore unknown actions, and if
371 not IPv6-aware, should exit if the environment
372 variable DNSMASQ_IAID is set. The use-case for this is
373 to track netboot/install. Suggestion from Shantanu
376 Update contrib/port-forward/dnsmasq-portforward to reflect
379 Set the environment variable DNSMASQ_LOG_DHCP when running
380 the script id --log-dhcp is in effect, so that script can
381 taylor their logging verbosity. Suggestion from Malte
384 Arrange that addresses specified with --listen-address
385 work even if there is no interface carrying the
386 address. This is chiefly useful for IPv4 loopback
387 addresses, where any address in 127.0.0.0/8 is a valid
388 loopback address, but normally only 127.0.0.1 appears on
389 the lo interface. Thanks to Mathieu Trudel-Lapierre for
390 the idea and initial patch.
392 Fix crash, introduced in 2.60, when a DHCPINFORM is
393 received from a network which has no valid dhcp-range.
394 Thanks to Stephane Glondu for the bug report.
396 Add a new DHCP lease time keyword, "deprecated" for
397 --dhcp-range. This is only valid for IPv6, and sets the
398 preffered lease time for both DHCP and RA to zero. The
399 effect is that clients can continue to use the address
400 for existing connections, but new connections will use
401 other addresses, if they exist. This makes hitless
402 renumbering at least possible.
404 Fix bug in address6_available() which caused DHCPv6 lease
405 aquisition to fail if more than one dhcp-range in use.
407 Provide RDNSS and DNSSL data in router advertisements,
408 using the settings provided for DHCP options
409 option6:domain-search and option6:dns-server.
411 Tweak logo/favicon.ico to add some transparency. Thanks to
412 SamLT for work on this.
414 Don't cache data from non-recursive nameservers, since it
415 may erroneously look like a valid CNAME to a non-exitant
416 name. Thanks to Ben Winslow for finding this.
418 Call SO_BINDTODEVICE on the DHCP socket(s) when doing DHCP
419 on exactly one interface and --bind-interfaces is set. This
420 makes the OpenStack use-case of one dnsmasq per virtual
421 interface work. This is only available on Linux; it's not
422 supported on other platforms. Thanks to Vishvananda Ishaya
423 and the OpenStack team for the suggestion.
425 Updated French translation. Thanks to Gildas Le Nadan.
427 Give correct from-cache answers to explict CNAME queries.
428 Thanks to Rob Zwissler for spotting this.
430 Add --tftp-lowercase option. Thanks to Oliver Rath for the
433 Ensure that the DBus DhcpLeaseUpdated events are generated
434 when a lease goes through INIT_REBOOT state, even if the
435 dhcp-script is not in use. Thanks to Antoaneta-Ecaterina
438 Fix failure of TFTP over IPv4 on OpenBSD platform. Thanks
439 to Brad Smith for spotting this.
443 Fix compilation problem in Mac OS X Lion. Thanks to Olaf
444 Flebbe for the patch.
446 Fix DHCP when using --listen-address with an IP address
447 which is not the primary address of an interface.
449 Add --dhcp-client-update option.
451 Add Lua integration. Dnsmasq can now execute a DHCP
452 lease-change script written in Lua. This needs to be
453 enabled at compile time by setting HAVE_LUASCRIPT in
454 src/config.h or running "make COPTS=-DHAVE_LUASCRIPT"
455 Thanks to Jan-Piet Mens for the idea and proof-of-concept
458 Tidied src/config.h to distinguish between
459 platform-dependent compile-time options which are selected
460 automatically, and builder-selectable compile time
461 options. Document the latter better, and describe how to
462 set them from the make command line.
464 Tidied up IPPROTO_IP/SOL_IP (and IPv6 equivalent)
465 confusion. IPPROTO_IP works everywhere now.
467 Set TOS on DHCP sockets, this improves things on busy
468 wireless networks. Thanks to Dave Taht for the patch.
470 Determine VERSION automatically based on git magic:
471 release tags or hash values.
473 Improve start-up speed when reading large hosts files
474 containing many distinct addresses.
476 Fix problem if dnsmasq is started without the stdin,
477 stdout and stderr file descriptors open. This can manifest
478 itself as 100% CPU use. Thanks to Chris Moore for finding
481 Fix shell-scripting bug in bld/pkg-wrapper. Thanks to
482 Mark Mitchell for the patch.
484 Allow the TFP server or boot server in --pxe-service, to
485 be a domain name instead of an IP address. This allows for
486 round-robin to multiple servers, in the same way as
487 --dhcp-boot. A good suggestion from Cristiano Cumer.
489 Support BUILDDIR variable in the Makefile. Allows builds
490 for multiple archs from the same source tree with eg.
491 make BUILDDIR=linux (relative to dnsmasq tree)
492 make BUILDDIR=/tmp/openbsd (absolute path)
493 If BUILDDIR is not set, compilation happens in the src
494 directory, as before. Suggestion from Mark Mitchell.
496 Support DHCPv6. Support is there for the sort of things
497 the existing v4 server does, including tags, options,
498 static addresses and relay support. Missing is prefix
499 delegation, which is probably not required in the dnsmasq
500 niche, and an easy way to accept prefix delegations from
501 an upstream DHCPv6 server, which is. Future plans include
502 support for DHCPv6 router option and MAC address option
503 (to make selecting clients by MAC address work like IPv4).
504 These will be added as the standards mature.
505 This code has been tested, but this is the first release,
506 so don't bet the farm on it just yet. Many thanks to all
507 testers who have got it this far.
509 Support IPv6 router advertisements. This is a
510 simple-minded implementation, aimed at providing the
511 vestigial RA needed to go alongside IPv6. Is picks up
512 configuration from the DHCPv6 conf, and should just need
513 enabling with --enable-ra.
515 Fix long-standing wrinkle with --localise-queries that
516 could result in wrong answers when DNS packets arrive
517 via an interface other than the expected one. Thanks to
518 Lorenzo Milesi and John Hanks for spotting this one.
520 Update French translation. Thanks to Gildas Le Nadan.
522 Update Polish translation. Thanks to Jan Psota.
526 Fix regression in 2.58 which caused failure to start up
527 with some combinations of dnsmasq config and IPv6 kernel
528 network config. Thanks to Brielle Bruns for the bug
531 Improve dnsmasq's behaviour when network interfaces are
532 still doing duplicate address detection (DAD). Previously,
533 dnsmasq would wait up to 20 seconds at start-up for the
534 DAD state to terminate. This is broken for bridge
535 interfaces on recent Linux kernels, which don't start DAD
536 until the bridge comes up, and so can take arbitrary
537 time. The new behaviour lets dnsmasq poll for an arbitrary
538 time whilst providing service on other interfaces. Thanks
539 to Stephen Hemminger for pointing out the problem.
543 Provide a definition of the SA_SIZE macro where it's
544 missing. Fixes build failure on openBSD.
546 Don't include a zero terminator at the end of messages
547 sent to /dev/log when /dev/log is a datagram socket.
548 Thanks to Didier Rabound for spotting the problem.
550 Add --dhcp-sequential-ip flag, to force allocation of IP
551 addresses in ascending order. Note that the default
552 pseudo-random mode is in general better but some
553 server-deployment applications need this.
555 Fix problem where a server-id of 0.0.0.0 is sent to a
556 client when a dhcp-relay is in use if a client renews a
557 lease after dnsmasq restart and before any clients on the
558 subnet get a new lease. Thanks to Mike Ruiz for assistance
559 in chasing this one down.
561 Don't return NXDOMAIN to an AAAA query if we have CNAME
562 which points to an A record only: NODATA is the correct
563 reply in this case. Thanks to Tom Fernandes for spotting
566 Relax the need to supply a netmask in --dhcp-range for
567 networks which use a DHCP relay. Whilst this is still
568 desireable, in the absence of a netmask dnsmasq will use
569 a default based on the class (A, B, or C) of the address.
570 This should at least remove a cause of mysterious failure
571 for people using RFC1918 addresses and relays.
573 Add support for Linux conntrack connection marking. If
574 enabled with --conntrack, the connection mark for incoming
575 DNS queries will be copied to the outgoing connections
576 used to answer those queries. This allows clever firewall
577 and accounting stuff. Only available if dnsmasq is
578 compiled with HAVE_CONNTRACK and adds a dependency on
579 libnetfilter-conntrack. Thanks to Ed Wildgoose for the
580 initial idea, testing and sponsorship of this function.
582 Provide a sane error message when someone attempts to
583 match a tag in --dhcp-host.
585 Tweak the behaviour of --domain-needed, to avoid problems
586 with recursive nameservers downstream of dnsmasq. The new
587 behaviour only stops A and AAAA queries, and returns
588 NODATA rather than NXDOMAIN replies.
590 Efficiency fix for very large DHCP configurations, thanks
591 to James Gartrell and Mike Ruiz for help with this.
593 Allow the TFTP-server address in --dhcp-boot to be a
594 domain-name which is looked up in /etc/hosts. This can
595 give multiple IP addresses which are used round-robin,
596 thus doing TFTP server load-balancing. Thanks to Sushil
597 Agrawal for the patch.
599 When two tagged dhcp-options for a particular option
600 number are both valid, use the one which is valid without
601 a tag from the dhcp-range. Allows overriding of the value
602 of a DHCP option for a particular host as well as
603 per-network values. So
604 --dhcp-range=set:interface1,......
605 --dhcp-host=set:myhost,.....
606 --dhcp-option=tag:interface1,option:nis-domain,"domain1"
607 --dhcp-option=tag:myhost,option:nis-domain,"domain2"
608 will set the NIS-domain to domain1 for hosts in the range, but
609 override that to domain2 for a particular host.
611 Fix bug which resulted in truncated files and timeouts for
612 some TFTP transfers. The bug only occurs with netascii
613 transfers and needs an unfortunate relationship between
614 file size, blocksize and the number of newlines in the
615 last block before it manifests itself. Many thanks to
616 Alkis Georgopoulos for spotting the problem and providing
617 a comprehensive test-case.
619 Fix regression in TFTP server on *BSD platforms introduced
620 in version 2.56, due to confusion with sockaddr
621 length. Many thanks to Loic Pefferkorn for finding this.
623 Support scope-ids in IPv6 addresses of nameservers from
624 /etc/resolv.conf and in --server options. Eg
625 nameserver fe80::202:a412:4512:7bbf%eth0 or
626 server=fe80::202:a412:4512:7bbf%eth0. Thanks to
627 Michael Stapelberg for the suggestion.
629 Update Polish translation, thanks to Jan Psota.
631 Update French translation. Thanks to Gildas Le Nadan.
635 Add patches to allow build under Android.
637 Provide our own header for the DNS protocol, rather than
638 relying on arpa/nameser.h. This has proved more or less
639 defective over the years and the final straw is that it's
640 effectively empty on Android.
642 Fix regression in 2.56 which caused hex constants in
643 configuration to be rejected if they contain the '*'
646 Correct wrong casts of arguments to ctype.h functions,
647 isdigit(), isxdigit() etc. Thanks to Matthias Andree for
650 Allow build with IDN support independently from i18n.
651 IDN support continues to be included automatically
652 when i18n is included.
653 'make COPTS=-DHAVE_IDN' is the magic incantation.
655 Modify check on extraneous command line junk (added in
656 2.56) so that it doesn't complain about extra _empty_
657 arguments. Otherwise this breaks libvirt.
661 Add a patch to allow dnsmasq to get interface names right in a
662 Solaris zone. Thanks to Dj Padzensky for this.
664 Improve data-type parsing heuristics so that
665 --dhcp-option=option:domain-search,.
666 treats the value as a string and not an IP address.
667 Thanks to Clemens Fischer for spotting that.
669 Add IPv6 support to the TFTP server. Many thanks to Jan
670 'RedBully' Seiffert for the patches.
672 Log DNS queries at level LOG_INFO, rather then
673 LOG_DEBUG. This makes things consistent with DHCP
674 logging. Thanks to Adam Pribyl for spotting the problem.
676 Ensure that dnsmasq terminates cleanly when using
677 --syslog-async even if it cannot make a connection to the
680 Add --add-mac option. This is to support currently
681 experimental DNS filtering facilities. Thanks to Benjamin
682 Petrin for the orignal patch.
684 Fix bug which meant that tags were ignored in dhcp-range
685 configuration specifying PXE-proxy service. Thanks to
686 Cristiano Cumer for spotting this.
688 Raise an error if there is extra junk, not part of an
689 option, on the command line.
691 Flag a couple of log messages in cache.c as coming from
692 the DHCP subsystem. Thanks to Olaf Westrik for the patch.
694 Omit timestamps from logs when a) logging to stderr and
695 b) --keep-in-forground is set. The logging facility on the
696 other end of stderr can be assumned to supply them. Thanks
697 to John Hallam for the patch.
699 Don't complain about strings longer than 255 characters in
700 --txt-record, just split the long strings into 255
701 character chunks instead.
703 Fix crash on double-free. This bug can only happen when
704 dhcp-script is in use and then only in rare circumstances
705 triggered by high DHCP transaction rate and a slow
706 script. Thanks to Ferenc Wagner for finding the problem.
708 Only log that a file has been sent by TFTP after the
709 transfer has completed succesfully.
711 A good suggestion from Ferenc Wagner: extend
712 the --domain option to allow this sort of thing:
713 --domain=thekelleys.org.uk,192.168.0.0/24,local
714 which automatically creates
715 --local=/thekelleys.org.uk/
716 --local=/0.168.192.in-addr.arpa/
718 Tighten up syntax checking of hex contants in the config
719 file. Thanks to Fred Damen for spotting this.
721 Add dnsmasq logo/icon, contributed by Justin Swift. Many
724 Never cache DNS replies which have the 'cd' bit set, or
725 which result from queries forwarded with the 'cd' bit
726 set. The 'cd' bit instructs a DNSSEC validating server
727 upstream to ignore signature failures and return replies
728 anyway. Without this change it's possible to pollute the
729 dnsmasq cache with bad data by making a query with the
730 'cd' bit set and subsequent queries would return this data
731 without its being marked as suspect. Thanks to Anders
732 Kaseorg for pointing out this problem.
734 Add --proxy-dnssec flag, for compliance with RFC
735 4035. Dnsmasq will now clear the 'ad' bit in answers returned
736 from upstream validating nameservers unless this option is
739 Allow a filename of "-" for --conf-file to read
740 stdin. Suggestion from Timothy Redaelli.
742 Rotate the order of SRV records in replies, to provide
743 round-robin load balancing when all the priorities are
744 equal. Thanks to Peter McKinney for the suggestion.
747 contrib/MacOSX-launchd/uk.org.thekelleys.dnsmasq.plist
748 so that it doesn't log all queries to a file by
749 default. Thanks again to Peter McKinney.
751 By default, setting an IPv4 address for a domain but not
752 an IPv6 address causes dnsmasq to return
753 an NODATA reply for IPv6 (or vice-versa). So
754 --address=/google.com/1.2.3.4 stops IPv6 queries for
755 *google.com from being forwarded. Make it possible to
756 override this behaviour by defining the sematics if the
757 same domain appears in both --server and --address.
758 In that case, the --address has priority for the address
759 family in which is appears, but the --server has priority
760 of the address family which doesn't appear in --adddress
762 --address=/google.com/1.2.3.4
763 --server=/google.com/#
764 will return 1.2.3.4 for IPv4 queries for *.google.com but
765 forward IPv6 queries to the normal upstream nameserver.
766 Similarly when setting an IPv6 address
767 only this will allow forwarding of IPv4 queries. Thanks to
768 William for pointing out the need for this.
770 Allow more than one --dhcp-optsfile and --dhcp-hostsfile
771 and make them understand directories as arguments in the
772 same way as --addn-hosts. Suggestion from John Hanks.
774 Ignore rebinding requests for leases we don't know
775 about. Rebind is broadcast, so we might get to overhear a
776 request meant for another DHCP server. NAKing this is
777 wrong. Thanks to Brad D'Hondt for assistance with this.
779 Fix cosmetic bug which produced strange output when
780 dumping cache statistics with some configurations. Thanks
781 to Fedor Kozhevnikov for spotting this.
785 Fix crash when /etc/ethers is in use. Thanks to
786 Gianluigi Tiesi for finding this.
788 Fix crash in netlink_multicast(). Thanks to Arno Wald for
791 Allow the empty domain "." in dhcp domain-search (119)
796 There is no version 2.54 to avoid confusion with 2.53,
797 which incorrectly identifies itself as 2.54.
801 Fix failure to compile on Debian/kFreeBSD. Thanks to
802 Axel Beckert and Petr Salinger.
804 Fix code to avoid scary strict-aliasing warnings
805 generated by gcc 4.4.
807 Added FAQ entry warning about DHCP failures with Vista
808 when firewalls block 255.255.255.255.
810 Fixed bug which caused bad things to happen if a
811 resolv.conf file which exists is subsequently removed.
812 Thanks to Nikolai Saoukh for the patch.
814 Rationalised the DHCP tag system. Every configuration item
815 which can set a tag does so by adding "set:<tag>" and
816 every configuration item which is conditional on a tag is
817 made so by "tag:<tag>". The NOT operator changes to '!',
818 which is a bit more intuitive too. Dhcp-host directives
819 can set more than one tag now. The old '#' NOT,
820 "net:" prefix and no-prefixes are still honoured, so
821 no existing config file needs to be changed, but
822 the documentation and new-style config files should be
825 Added --tag-if to allow boolean operations on tags.
826 This allows complicated logic to be clearer and more
827 general. A great suggestion from Richard Voigt.
829 Add broadcast/unicast information to DHCP logging.
831 Allow --dhcp-broadcast to be unconditional.
833 Fixed incorrect behaviour with NOT <tag> conditionals in
834 dhcp-options. Thanks to Max Turkewitz for assistance
837 If we send vendor-class encapsulated options based on the
838 vendor-class supplied by the client, and no explicit
839 vendor-class option is given, echo back the vendor-class
842 Fix bug which stopped dnsmasq from matching both a
843 circuitid and a remoteid. Thanks to Ignacio Bravo for
846 Add --dhcp-proxy, which makes it possible to configure
847 dnsmasq to use a DHCP relay agent as a full proxy, with
848 all DHCP messages passing through the proxy. This is
849 useful if the relay adds extra information to the packets
850 it forwards, but cannot be configured with the RFC 5107
851 server-override option.
853 Added interface:<iface name> part to dhcp-range. The
854 semantics of this are very odd at first sight, but it
855 allows a single line of the form
856 dhcp-range=interface:virt0,192.168.0.4,192.168.0.200
857 to be added to dnsmasq configuration which then supplies
858 DHCP and DNS services to that interface, without affecting
859 what services are supplied to other interfaces and
860 irrespective of the existance or lack of
861 interface=<interface>
862 lines elsewhere in the dnsmasq configuration. The idea is
863 that such a line can be added automatically by libvirt
864 or equivalent systems, without disturbing any manual
867 Similarly to the above, allow --enable-tftp=<interface>
869 Allow a TFTP root to be set separately for requests via
870 different interfaces, --tftp-root=<path>,<interface>
872 Correctly handle and log clashes between CNAMES and
873 DNS names being given to DHCP leases. This fixes a bug
874 which caused nonsense IP addresses to be logged. Thanks to
875 Sergei Zhirikov for finding and analysing the problem.
877 Tweak flush_log so as to avoid leaving the log
878 file in non-blocking mode. O_NONBLOCK is a property of the
879 file, not the process/descriptor.
881 Fix contrib/Solaris10/create_package
882 (/usr/man -> /usr/share/man) Thanks to Vita Batrla.
884 Fix a problem where, if a client got a lease, then went
885 to another subnet and got another lease, then moved back,
886 it couldn't resume the old lease, but would instead get
887 a new address. Thanks to Leonardo Rodrigues for spotting
888 this and testing the fix.
890 Fix weird bug which sometimes omitted certain characters
891 from the start of quoted strings in dhcp-options. Thanks
892 to Dayton Turner for spotting the problem.
894 Add facility to redirect some domains to the standard
895 upstream servers: this allows something like
896 --server=/google.com/1.2.3.4 --server=/www.google.com/#
897 which will send queries for *.google.com to 1.2.3.4,
898 except *www.google.com which will be forwarded as usual.
899 Thanks to AJ Weber for prompting this addition.
901 Improve the hash-algorithm used to generate IP addresses
902 from MAC addresses during initial DHCP address
903 allocation. This improves performance when large numbers
904 of hosts with similar MAC addresses all try and get an IP
905 address at the same time. Thanks to Paul Smith for his
908 Tweak DHCP code so that --bridge-interface can be used to
909 select which IP alias of an interface should be used for
910 DHCP purposes on Linux. If eth0 has an alias eth0:dhcp
911 then adding --bridge-interface=eth0:dhcp,eth0 will use
912 the address of eth0:dhcp to determine the correct subnet
913 for DHCP address allocation. Thanks to Pawel Golaszewski
914 for prompting this and Eric Cooper for further testing.
916 Add --dhcp-generate-names. Suggestion by Ferenc Wagner.
918 Tweak DNS server selection algorithm when there is more
919 than one server available for a domain, eg.
920 --server=/mydomain/1.1.1.1
921 --server=/mydomain/2.2.2.2
922 Thanks to Alberto Cuesta-Canada for spotting a weakness
925 Add --max-ttl. Thanks to Fredrik Ringertz for the patch.
927 Allow --log-facility=- to force all logging to
928 stderr. Suggestion from Clemens Fischer.
930 Fix regression which caused configuration like
931 --address=/.domain.com/1.2.3.4 to be rejected. The dot to the
932 left of the domain has been implied and not required for a
933 long time, but it should be accepted for backward
934 compatibility. Thanks to Andrew Burcin for spotting this.
936 Add --rebind-domain-ok and --rebind-localhost-ok.
937 Suggestion from Clemens Fischer.
939 Log replies to queries of type TXT, when --log-queries
942 Fix compiler warnings when compiled with -DNO_DHCP. Thanks
943 to Shantanu Gadgil for the patch.
945 Updated French translation. Thanks to Gildas Le Nadan.
947 Updated Polish translation. Thanks to Jan Psota.
949 Updated German translation. Thanks to Matthias Andree.
951 Added contrib/static-arp, thanks to Darren Hoo.
953 Fix corruption of the domain when a name from /etc/hosts
954 overrides one supplied by a DHCP client. Thanks to Fedor
955 Kozhevnikov for spotting the problem.
957 Updated Spanish translation. Thanks to Chris Chatham.
961 Work around a Linux kernel bug which insists that the
962 length of the option passed to setsockopt must be at least
963 sizeof(int) bytes, even if we're calling SO_BINDTODEVICE
964 and the device name is "lo". Note that this is fixed
965 in kernel 2.6.31, but the workaround is harmless and
966 allows earlier kernels to be used. Also fix dnsmasq
967 bug which reported the wrong address when this failed.
968 Thanks to Fedor for finding this.
970 The API for IPv6 PKTINFO changed around Linux kernel
971 2.6.14. Workaround the case where dnsmasq is compiled
972 against newer headers, but then run on an old kernel:
973 necessary for some *WRT distros.
975 Re-read the set of network interfaces when re-loading
976 /etc/resolv.conf if --bind-interfaces is not set. This
977 handles the case that loopback interfaces do not exist
978 when dnsmasq is first started.
980 Tweak the PXE code to support port 4011. This should
981 reduce broadcasts and make things more reliable when other
982 servers are around. It also improves inter-operability
983 with certain clients.
985 Make a pxe-service configuration with no filename or boot
986 service type legal: this does a local boot. eg.
987 pxe-service=x86PC, "Local boot"
989 Be more conservative in detecting "A for A"
990 queries. Dnsmasq checks if the name in a type=A query looks
991 like a dotted-quad IP address and answers the query itself
992 if so, rather than forwarding it. Previously dnsmasq
993 relied in the library function inet_addr() to convert
994 addresses, and that will accept some things which are
995 confusing in this context, like 1.2.3 or even just
996 1234. Now we only do A for A processing for four decimal
997 numbers delimited by dots.
999 A couple of tweaks to fix compilation on Solaris. Thanks
1000 to Joel Macklow for help with this.
1002 Another Solaris compilation tweak, needed for Solaris
1003 2009.06. Thanks to Lee Essen for that.
1005 Added extract packaging stuff from Lee Essen to
1008 Increased the default limit on number of leases to 1000
1009 (from 150). This is mainly a defence against DoS attacks,
1010 and for the average "one for two class C networks"
1011 installation, IP address exhaustion does that just as
1012 well. Making the limit greater than the number of IP
1013 addresses available in such an installation removes a
1014 surprise which otherwise can catch people out.
1016 Removed extraneous trailing space in the value of the
1017 DNSMASQ_TIME_REMAINING DNSMASQ_LEASE_LENGTH and
1018 DNSMASQ_LEASE_EXPIRES environment variables. Thanks to
1019 Gildas Le Nadan for spotting this.
1021 Provide the network-id tags for a DHCP transaction to
1022 the lease-change script in the environment variable
1023 DNSMASQ_TAGS. A good suggestion from Gildas Le Nadan.
1025 Add support for RFC3925 "Vendor-Identifying Vendor
1026 Options". The syntax looks like this:
1027 --dhcp-option=vi-encap:<enterprise number>, .........
1029 Add support to --dhcp-match to allow matching against
1030 RFC3925 "Vendor-Identifying Vendor Classes". The syntax
1032 --dhcp-match=tag,vi-encap<enterprise number>, <value>
1034 Add some application specific code to assist in
1035 implementing the Broadband forum TR069 CPE-WAN
1036 specification. The details are in contrib/CPE-WAN/README
1038 Increase the default DNS packet size limit to 4096, as
1039 recommended by RFC5625 section 4.4.3. This can be
1040 reconfigured using --edns-packet-max if needed. Thanks to
1041 Francis Dupont for pointing this out.
1043 Rewrite query-ids even for TSIG signed packets, since
1044 this is allowed by RFC5625 section 4.5.
1046 Use getopt_long by default on OS X. It has been supported
1047 since version 10.3.0. Thanks to Arek Dreyer for spotting
1050 Added up-to-date startup configuration for MacOSX/launchd
1051 in contrib/MacOSX-launchd. Thanks to Arek Dreyer for
1054 Fix link error when including Dbus but excluding DHCP.
1055 Thanks to Oschtan for the bug report.
1057 Updated French translation. Thanks to Gildas Le Nadan.
1059 Updated Polish translation. Thanks to Jan Psota.
1061 Updated Spanish translation. Thanks to Chris Chatham.
1063 Fixed confusion about domains, when looking up DHCP hosts
1064 in /etc/hosts. This could cause spurious "Ignoring
1065 domain..." messages. Thanks to Fedor Kozhevnikov for
1066 finding and analysing the problem.
1070 Add support for internationalised DNS. Non-ASCII characters
1071 in domain names found in /etc/hosts, /etc/ethers and
1072 /etc/dnsmasq.conf will be correctly handled by translation to
1073 punycode, as specified in RFC3490. This function is only
1074 available if dnsmasq is compiled with internationalisation
1075 support, and adds a dependency on GNU libidn. Without i18n
1076 support, dnsmasq continues to be compilable with just
1077 standard tools. Thanks to Yves Dorfsman for the
1080 Add two more environment variables for lease-change scripts:
1081 First, DNSMASQ_SUPPLIED_HOSTNAME; this is set to the hostname
1082 supplied by a client, even if the actual hostname used is
1083 over-ridden by dhcp-host or dhcp-ignore-names directives.
1084 Also DNSMASQ_RELAY_ADDRESS which gives the address of
1085 a DHCP relay, if used.
1086 Suggestions from Michael Rack.
1088 Fix regression which broke echo of relay-agent
1089 options. Thanks to Michael Rack for spotting this.
1091 Don't treat option 67 as being interchangeable with
1092 dhcp-boot parameters if it's specified as
1095 Make the code to call scripts on lease-change compile-time
1096 optional. It can be switched off by editing src/config.h
1097 or building with "make COPTS=-DNO_SCRIPT".
1099 Make the TFTP server cope with filenames from Windows/DOS
1100 which use '\' as pathname separator. Thanks to Ralf for
1103 Updated Polish translation. Thanks to Jan Psota.
1105 Warn if an IP address is duplicated in /etc/ethers. Thanks
1106 to Felix Schwarz for pointing this out.
1108 Teach --conf-dir to take an option list of file suffices
1109 which will be ignored when scanning the directory. Useful
1110 for backup files etc. Thanks to Helmut Hullen for the
1113 Add new DHCP option named tftpserver-address, which
1114 corresponds to the third argument of dhcp-boot. This
1115 allows the complete functionality of dhcp-boot to be
1116 replicated with dhcp-option. Useful when using
1119 Test which upstream nameserver to use every 10 seconds
1120 or 50 queries and not just when a query times out and
1121 is retried. This should improve performance when there
1122 is a slow nameserver in the list. Thanks to Joe for the
1125 Don't do any PXE processing, even for clients with the
1126 correct vendorclass, unless at least one pxe-prompt or
1127 pxe-service option is given. This stops dnsmasq
1128 interfering with proxy PXE subsystems when it is just
1129 the DHCP server. Thanks to Spencer Clark for spotting this.
1131 Limit the blocksize used for TFTP transfers to a value
1132 which avoids packet fragmentation, based on the MTU of the
1133 local interface. Many netboot ROMs can't cope with
1136 Honour dhcp-ignore configuration for PXE and proxy-PXE
1137 requests. Thanks to Niels Basjes for the bug report.
1139 Updated French translation. Thanks to Gildas Le Nadan.
1143 Fix security problem which allowed any host permitted to
1144 do TFTP to possibly compromise dnsmasq by remote buffer
1145 overflow when TFTP enabled. Thanks to Core Security
1146 Technologies and Iván Arce, Pablo Hernán Jorge, Alejandro
1147 Pablo Rodriguez, Martín Coco, Alberto Soliño Testa and
1148 Pablo Annetta. This problem has Bugtraq id: 36121
1151 Fix a problem which allowed a malicious TFTP client to
1152 crash dnsmasq. Thanks to Steve Grubb at Red Hat for
1153 spotting this. This problem has Bugtraq id: 36120 and
1158 Fix regression in 2.48 which disables the lease-change
1159 script. Thanks to Jose Luis Duran for spotting this.
1161 Log TFTP "file not found" errors. These were not logged,
1162 since a normal PXELinux boot generates many of them, but
1163 the lack of the messages seems to be more confusing than
1164 routinely seeing them when there is no real error.
1166 Update Spanish translation. Thanks to Chris Chatham.
1170 Archived the extensive, backwards, changelog to
1171 CHANGELOG.archive. The current changelog now runs from
1172 version 2.43 and runs conventionally.
1174 Fixed bug which broke binding of servers to physical
1175 interfaces when interface names were longer than four
1176 characters. Thanks to MURASE Katsunori for the patch.
1178 Fixed netlink code to check that messages come from the
1179 correct source, and not another userspace process. Thanks
1180 to Steve Grubb for the patch.
1182 Maintainability drive: removed bug and missing feature
1183 workarounds for some old platforms. Solaris 9, OpenBSD
1184 older than 4.1, Glibc older than 2.2, Linux 2.2.x and
1185 DBus older than 1.1.x are no longer supported.
1187 Don't read included configuration files more than once:
1188 allows complex configuration structures without problems.
1190 Mark log messages from the various subsystems in dnsmasq:
1191 messages from the DHCP subsystem now have the ident string
1192 "dnsmasq-dhcp" and messages from TFTP have ident
1193 "dnsmasq-tftp". Thanks to Olaf Westrik for the patch.
1195 Fix possible infinite DHCP protocol loop when an IP
1196 address nailed to a hostname (not a MAC address) and a
1197 host sometimes provides the name, sometimes not.
1199 Allow --addn-hosts to take a directory: all the files
1200 in the directory are read. Thanks to Phil Cornelius for
1203 Support --bridge-interface on all platforms, not just BSD.
1205 Added support for advanced PXE functions. It's now
1206 possible to define a prompt and menu options which will
1207 be displayed when a client PXE boots. It's also possible to
1208 hand-off booting to other boot servers. Proxy-DHCP, where
1209 dnsmasq just supplies the PXE information and another DHCP
1210 server does address allocation, is also allowed. See the
1211 --pxe-prompt and --pxe-service keywords. Thanks to
1212 Alkis Georgopoulos for the suggestion and Guilherme Moro
1213 and Michael Brown for assistance.
1215 Improvements to DHCP logging. Thanks to Tom Metro for
1218 Add ability to build dnsmasq without DHCP support. To do
1219 this, edit src/config.h or build with
1220 "make COPTS=-DNO_DHCP". Thanks to Mahavir Jain for the patch.
1222 Added --test command-line switch - syntax check
1223 configuration files only.
1225 Updated French translation. Thanks to Gildas Le Nadan.
1229 Updated French translation. Thanks to Gildas Le Nadan.
1231 Fixed interface enumeration code to work on NetBSD
1232 5.0. Thanks to Roy Marples for the patch.
1234 Updated config.h to use the same location for the lease
1235 file on NetBSD as the other *BSD variants. Also allow
1236 LEASEFILE and CONFFILE symbols to be overriden in CFLAGS.
1238 Handle duplicate address detection on IPv6 more
1239 intelligently. In IPv6, an interface can have an address
1240 which is not usable, because it is still undergoing DAD
1241 (such addresses are marked "tentative"). Attempting to
1242 bind to an address in this state returns an error,
1243 EADDRNOTAVAIL. Previously, on getting such an error,
1244 dnsmasq would silently abandon the address, and never
1245 listen on it. Now, it retries once per second for 20
1246 seconds before generating a fatal error. 20 seconds should
1247 be long enough for any DAD process to complete, but can be
1248 adjusted in src/config.h if necessary. Thanks to Martin
1249 Krafft for the bug report.
1251 Add DBus introspection. Patch from Jeremy Laine.
1253 Update Dbus configuration file. Patch from Colin Walters.
1255 http://bugs.freedesktop.org/show_bug.cgi?id=18961
1257 Support arbitrarily encapsulated DHCP options, suggestion
1258 and initial patch from Samium Gromoff. This is useful for
1259 (eg) gPXE, which expect all its private options to be
1260 encapsulated inside a single option 175. So, eg,
1262 dhcp-option = encap:175, 190, "iscsi-client0"
1263 dhcp-option = encap:175, 191, "iscsi-client0-secret"
1265 will provide iSCSI parameters to gPXE.
1267 Enhance --dhcp-match to allow testing of the contents of a
1268 client-sent option, as well as its presence. This
1269 application in mind for this is RFC 4578
1270 client-architecture specifiers, but it's generally useful.
1271 Joey Korkames suggested the enhancement.
1273 Move from using the IP_XMIT_IF ioctl to IP_BOUND_IF on
1274 OpenSolaris. Thanks to Bastian Machek for the heads-up.
1276 No longer complain about blank lines in
1277 /etc/ethers. Thanks to Jon Nelson for the patch.
1279 Fix binding of servers to physical devices, eg
1280 --server=/domain/1.2.3.4@eth0 which was broken from 2.43
1281 onwards unless --query-port=0 set. Thanks to Peter Naulls
1284 Reply to DHCPINFORM requests even when the supplied ciaddr
1285 doesn't fall in any dhcp-range. In this case it's not
1286 possible to supply a complete configuration, but
1287 individually-configured options (eg PAC) may be useful.
1289 Allow the source address of an alias to be a range:
1290 --alias=192.168.0.0,10.0.0.0,255.255.255.0 maps the whole
1291 subnet 192.168.0.0->192.168.0.255 to 10.0.0.0->10.0.0.255,
1293 --alias=192.168.0.10-192.168.0.40,10.0.0.0,255.255.255.0
1294 maps only the 192.168.0.10->192.168.0.40 region. Thanks to
1295 Ib Uhrskov for the suggestion.
1297 Don't dynamically allocate DHCP addresses which may break
1298 Windows. Addresses which end in .255 or .0 are broken in
1299 Windows even when using supernetting.
1300 --dhcp-range=192.168.0.1,192.168.1.254,255,255,254.0 means
1301 192.168.0.255 is a valid IP address, but not for Windows.
1302 See Microsoft KB281579. We therefore no longer allocate
1303 these addresses to avoid hard-to-diagnose problems.
1305 Update Polish translation. Thanks to Jan Psota.
1307 Delete the PID-file when dnsmasq shuts down. Note that by
1308 this time, dnsmasq is normally not running as root, so
1309 this will fail if the PID-file is stored in a root-owned
1310 directory; such failure is silently ignored. To take
1311 advantage of this feature, the PID-file must be stored in a
1312 directory owned and write-able by the user running
1317 Allow --bootp-dynamic to take a netid tag, so that it may
1318 be selectively enabled. Thanks to Olaf Westrik for the
1321 Remove ISC-leasefile reading code. This has been
1322 deprecated for a long time, and last time I removed it, it
1323 ended up going back by request of one user. This time,
1324 it's gone for good; otherwise it would need to be
1325 re-worked to support multiple domains (see below).
1327 Support DHCP clients in multiple DNS domains. This is a
1328 long-standing request. Clients are assigned to a domain
1329 based in their IP address.
1331 Add --dhcp-fqdn flag, which changes behaviour if DNS names
1332 assigned to DHCP clients. When this is set, there must be
1333 a domain associated with each client, and only
1334 fully-qualified domain names are added to the DNS. The
1335 advantage is that the only the FQDN needs to be unique,
1336 so that two or more DHCP clients can share a hostname, as
1337 long as they are in different domains.
1339 Set environment variable DNSMASQ_DOMAIN when invoking
1340 lease-change script. This may be useful information to
1341 have now that it's variable.
1343 Tighten up data-checking code for DNS packet
1344 handling. Thanks to Steve Dodd who found certain illegal
1345 packets which could crash dnsmasq. No memory overwrite was
1346 possible, so this is not a security issue beyond the DoS
1349 Update example config dhcp option 47, the previous
1350 suggestion generated an illegal, zero-length,
1351 option. Thanks to Matthias Andree for finding this.
1353 Rewrite hosts-file reading code to remove the limit of
1354 1024 characters per line. John C Meuser found this.
1356 Create a net-id tag with the name of the interface on
1357 which the DHCP request was received.
1359 Fixed minor memory leak in DBus code, thanks to Jeremy
1360 Laine for the patch.
1362 Emit DBus signals as the DHCP lease database
1363 changes. Thanks to Jeremy Laine for the patch.
1365 Allow for more that one MAC address in a dhcp-host
1366 line. This configuration tells dnsmasq that it's OK to
1367 abandon a DHCP lease of the fixed address to one MAC
1368 address, if another MAC address in the dhcp-host statement
1369 asks for an address. This is useful to give a fixed
1370 address to a host which has two network interfaces
1371 (say, a laptop with wired and wireless interfaces.)
1372 It's very important to ensure that only one interface
1373 at a time is up, since dnsmasq abandons the first lease
1374 and re-uses the address before the leased time has
1375 elapsed. John Gray suggested this.
1377 Tweak the response to a DHCP request packet with a wrong
1378 server-id when --dhcp-authoritative is set; dnsmasq now
1379 returns a DHCPNAK, rather than silently ignoring the
1380 packet. Thanks to Chris Marget for spotting this
1383 Add --cname option. This provides a limited alias
1384 function, usable for DHCP names. Thanks to AJ Weber for
1385 suggestions on this.
1387 Updated contrib/webmin with latest version from Neil
1390 Updated Polish translation. Thanks to Jan Psota.
1392 Correct the text names for DHCP options 64 and 65 to be
1393 "nis+-domain" and "nis+-servers".
1395 Updated Spanish translation. Thanks to Chris Chatham.
1397 Force re-reading of /etc/resolv.conf when an "interface
1402 Fix total DNS failure in release 2.44 unless --min-port
1403 specified. Thanks to Steven Barth and Grant Coady for
1404 bugreport. Also reject out-of-range port spec, which could
1405 break things too: suggestion from Gilles Espinasse.
1409 Fix crash when unknown client attempts to renew a DHCP
1410 lease, problem introduced in version 2.43. Thanks to
1411 Carlos Carvalho for help chasing this down.
1413 Fix potential crash when a host which doesn't have a lease
1414 does DHCPINFORM. Again introduced in 2.43. This bug has
1415 never been reported in the wild.
1417 Fix crash in netlink code introduced in 2.43. Thanks to
1418 Jean Wolter for finding this.
1420 Change implementation of min_port to work even if min-port
1423 Patch to enable compilation of latest Mac OS X. Thanks to
1426 Update Spanish translation. Thanks to Christopher Chatham.
1430 Updated Polish translation. Thanks to Jan Psota.
1432 Flag errors when configuration options are repeated
1435 Further tweaks for GNU/kFreeBSD
1437 Add --no-wrap to msgmerge call - provides nicer .po file
1440 Honour lease-time spec in dhcp-host lines even for
1441 BOOTP. The user is assumed to known what they are doing in
1442 this case. (Hosts without the time spec still get infinite
1443 leases for BOOTP, over-riding the default in the
1444 dhcp-range.) Thanks to Peter Katzmann for uncovering this.
1446 Fix problem matching relay-agent ids. Thanks to Michael
1447 Rack for the bug report.
1449 Add --naptr-record option. Suggestion from Johan
1452 Implement RFC 5107 server-id-override DHCP relay agent
1455 Apply patches from Stefan Kruger for compilation on
1456 Solaris 10 under Sun studio.
1458 Yet more tweaking of Linux capability code, to suppress
1459 pointless wingeing from kernel 2.6.25 and above.
1461 Improve error checking during startup. Previously, some
1462 errors which occurred during startup would be worked
1463 around, with dnsmasq still starting up. Some were logged,
1464 some silent. Now, they all cause a fatal error and dnsmasq
1465 terminates with a non-zero exit code. The errors are those
1466 associated with changing uid and gid, setting process
1467 capabilities and writing the pidfile. Thanks to Uwe
1468 Gansert and the Suse security team for pointing out
1469 this improvement, and Bill Reimers for good implementation
1472 Provide NO_LARGEFILE compile option to switch off largefile
1473 support when compiling against versions of uclibc which
1474 don't support it. Thanks to Stephane Billiart for the patch.
1476 Implement random source ports for interactions with
1477 upstream nameservers. New spoofing attacks have been found
1478 against nameservers which do not do this, though it is not
1479 clear if dnsmasq is vulnerable, since to doesn't implement
1480 recursion. By default dnsmasq will now use a different
1481 source port (and socket) for each query it sends
1482 upstream. This behaviour can suppressed using the
1483 --query-port option, and the old default behaviour
1484 restored using --query-port=0. Explicit source-port
1485 specifications in --server configs are still honoured.
1487 Replace the random number generator, for better
1488 security. On most BSD systems, dnsmasq uses the
1489 arc4random() RNG, which is secure, but on other platforms,
1490 it relied on the C-library RNG, which may be
1491 guessable and therefore allow spoofing. This release
1492 replaces the libc RNG with the SURF RNG, from Daniel
1493 J. Berstein's DJBDNS package.
1495 Don't attempt to change user or group or set capabilities
1496 if dnsmasq is run as a non-root user. Without this, the
1497 change from soft to hard errors when these fail causes
1498 problems for non-root daemons listening on high
1499 ports. Thanks to Patrick McLean for spotting this.
1501 Updated French translation. Thanks to Gildas Le Nadan.
1505 The changelog for version 2.42 and earlier is
1506 available in CHANGELOG.archive.
