[people/ms/dnsmasq.git] / CHANGELOG
1 version 2.67
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.
5
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).
14
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.
18
19 Add --synth-domain. Thanks to Vishvananda Ishaya for
20 suggesting this.
21
22 Fix failure to compile ipset.c if old kernel headers are
23 in use. Thanks to Eugene Rudoy for pointing this out.
24
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.
33
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
38 bug report.
39
40 Generalise --interface-name to cope with IPv6 addresses
41 and multiple addresses per interface per address family.
42
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.
46
47 Remove restriction on prefix-length in --auth-zone. Thanks
48 to Toke Hoiland-Jorgensen for suggesting this.
49
50 Log when the maximum number of concurrent DNS queries is
51 reached. Thanks to Marcelo Salhab Brogliato for the patch.
52
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
57 report.
58
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.
62
63 Fix crash with empty DHCP string options when adding zero
64 terminator. Thanks to Patrick McLean for the bug report.
65
66 Allow hostnames to start with a number, as allowed in
67 RFC-1123. Thanks to Kyle Mestery for the patch.
68
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.
73
74 Make --clear-on-reload apply to setting upstream servers
75 via DBus too.
76
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
83 arguing for this.
84
85 Fix MAC address enumeration on *BSD. Thanks to Brad Smith
86 for the bug report.
87
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
91 for suggesting this.
92
93 Make --listen-address higher priority than --except-interface
94 in all circumstances. Thanks to Thomas Hood for the bugreport.
95
96 Provide independent control over which interfaces get TFTP
97 service. If enable-tftp is given a list of interfaces, then TFTP
98 is provided on those. Without the list, the previous behaviour
99 (provide TFTP to the same interfaces we provide DHCP to)
100 is retained. Thanks to Lonnie Abelbeck for the suggestion.
101
102 Add --dhcp-relay config option. Many thanks to vtsl.net
103 for sponsoring this development.
104
105 Fix crash with empty tag: in --dhcp-range. Thanks to
106 Kaspar Schleiser for the bug report.
107
108 Add "baseline" and "bloatcheck" makefile targets, for
109 revealing size changes during development. Thanks to
110 Vladislav Grishenko for the patch.
111
112 Cope with DHCPv6 clients which send REQUESTs without
113 address options - treat them as SOLICIT with rapid commit.
114
115 Support identification of clients by MAC address in
116 DHCPv6. When using a relay, the relay must support RFC
117 6939 for this to work. It always works for directly
118 connected clients. Thanks to Vladislav Grishenko
119 for prompting this feature.
120
121 Remove the rule for constructed DHCP ranges that the local
122 address must be either the first or last address in the
123 range. This was originally to avoid SLAAC addresses, but
124 we now explicitly autoconfig and privacy addresses instead.
125
126 Update Polish translation. Thanks to Jan Psota.
127
128 Fix problem in DHCPv6 vendorclass/userclass matching
129 code. Thanks to Tanguy Bouzeloc for the patch.
130
131 Update Spanish transalation. Thanks to Vicente Soriano.
132
133 Add --ra-param option. Thanks to Vladislav Grishenko for
134 inspiration on this.
135
136
137 version 2.66
138 Add the ability to act as an authoritative DNS
139 server. Dnsmasq can now answer queries from the wider 'net
140 with local data, as long as the correct NS records are set
141 up. Only local data is provided, to avoid creating an open
142 DNS relay. Zone transfer is supported, to allow secondary
143 servers to be configured.
144
145 Add "constructed DHCP ranges" for DHCPv6. This is intended
146 for IPv6 routers which get prefixes dynamically via prefix
147 delegation. With suitable configuration, stateful DHCPv6
148 and RA can happen automatically as prefixes are delegated
149 and then deprecated, without having to re-write the
150 dnsmasq configuration file or restart the daemon. Thanks to
151 Steven Barth for extensive testing and development work on
152 this idea.
153
154 Fix crash on startup on Solaris 11. Regression probably
155 introduced in 2.61. Thanks to Geoff Johnstone for the
156 patch.
157
158 Add code to make behaviour for TCP DNS requests that same
159 as for UDP requests, when a request arrives for an allowed
160 address, but via a banned interface. This change is only
161 active on Linux, since the relevant API is missing (AFAIK)
162 on other platforms. Many thanks to Tomas Hozza for
163 spotting the problem, and doing invaluable discovery of
164 the obscure and undocumented API required for the solution.
165
166 Don't send the default DHCP option advertising dnsmasq as
167 the local DNS server if dnsmasq is configured to not act
168 as DNS server, or it's configured to a non-standard port.
169
170 Add DNSMASQ_CIRCUIT_ID, DNSMASQ_SUBCRIBER_ID,
171 DNSMASQ_REMOTE_ID variables to the environment of the
172 lease-change script (and the corresponding Lua). These hold
173 information inserted into the DHCP request by a DHCP relay
174 agent. Thanks to Lakefield Communications for providing a
175 bounty for this addition.
176
177 Fixed crash, introduced in 2.64, whilst handling DHCPv6
178 information-requests with some common configurations.
179 Thanks to Robert M. Albrecht for the bug report and
180 chasing the problem.
181
182 Add --ipset option. Thanks to Jason A. Donenfeld for the
183 patch.
184
185 Don't erroneously reject some option names in --dhcp-match
186 options. Thanks to Benedikt Hochstrasser for the bug report.
187
188 Allow a trailing '*' wildcard in all interface-name
189 configurations. Thanks to Christian Parpart for the patch.
190
191 Handle the situation where libc headers define
192 SO_REUSEPORT, but the kernel in use doesn't, to cope with
193 the introduction of this option to Linux. Thanks to Rich
194 Felker for the bug report.
195
196 Update Polish translation. Thanks to Jan Psota.
197
198 Fix crash if the configured DHCP lease limit is
199 reached. Regression occurred in 2.61. Thanks to Tsachi for
200 the bug report.
201
202 Update the French translation. Thanks to Gildas le Nadan.
203
204
205 version 2.65
206 Fix regression which broke forwarding of queries sent via
207 TCP which are not for A and AAAA and which were directed to
208 non-default servers. Thanks to Niax for the bug report.
209
210 Fix failure to build with DHCP support excluded. Thanks to
211 Gustavo Zacarias for the patch.
212
213 Fix nasty regression in 2.64 which completely broke cacheing.
214
215
216 version 2.64
217 Handle DHCP FQDN options with all flag bits zero and
218 --dhcp-client-update set. Thanks to Bernd Krumbroeck for
219 spotting the problem.
220
221 Finesse the check for /etc/hosts names which conflict with
222 DHCP names. Previously a name/address pair in /etc/hosts
223 which didn't match the name/address of a DHCP lease would
224 generate a warning. Now that only happesn if there is not
225 also a match. This allows multiple addresses for a name in
226 /etc/hosts with one of them assigned via DHCP.
227
228 Fix broken vendor-option processing for BOOTP. Thanks to
229 Hans-Joachim Baader for the bug report.
230
231 Don't report spurious netlink errors, regression in
232 2.63. Thanks to Vladislav Grishenko for the patch.
233
234 Flag DHCP or DHCPv6 in starup logging. Thanks to
235 Vladislav Grishenko for the patch.
236
237 Add SetServersEx method in DBus interface. Thanks to Dan
238 Williams for the patch.
239
240 Add SetDomainServers method in DBus interface. Thanks to
241 Roy Marples for the patch.
242
243 Fix build with later Lua libraries. Thansk to Cristian
244 Rodriguez for the patch.
245
246 Add --max-cache-ttl option. Thanks to Dennis Kaarsemaker
247 for the patch.
248
249 Fix breakage of --host-record parsing, resulting in
250 infinte loop at startup. Regression in 2.63. Thanks to
251 Haim Gelfenbeyn for spotting this.
252
253 Set SO_REUSEADDRESS and SO_V6ONLY options on the DHCPv6
254 socket, this allows multiple instances of dnsmasq on a
255 single machine, in the same way as for DHCPv4. Thanks to
256 Gene Czarcinski and Vladislav Grishenko for work on this.
257
258 Fix DHCPv6 to do access control correctly when it's
259 configured with --listen-address. Thanks to
260 Gene Czarcinski for sorting this out.
261
262 Add a "wildcard" dhcp-range which works for any IPv6
263 subnet, --dhcp-range=::,static Useful for Stateless
264 DHCPv6. Thanks to Vladislav Grishenko for the patch.
265
266 Don't include lease-time in DHCPACK replies to DHCPINFORM
267 queries, since RFC-2131 says we shouldn't. Thanks to
268 Wouter Ibens for pointing this out.
269
270 Makefile tweak to do dependency checking on header files.
271 Thanks to Johan Peeters for the patch.
272
273 Check interface for outgoing unsolicited router
274 advertisements, rather than relying on interface address
275 configuration. Thanks to Gene Czarinski for the patch.
276
277 Handle better attempts to transmit on interfaces which are
278 still doing DAD, and specifically do not just transmit
279 without setting source address and interface, since this
280 can cause very puzzling effects when a router
281 advertisement goes astray. Thanks again to Gene Czarinski.
282
283 Get RA timers right when there is more than one
284 dhcp-range on a subnet.
285
286
287 version 2.63
288 Do duplicate dhcp-host address check in --test mode.
289
290 Check that tftp-root directories are accessible before
291 start-up. Thanks to Daniel Veillard for the initial patch.
292
293 Allow more than one --tfp-root flag. The per-interface
294 stuff is pointless without that.
295
296 Add --bind-dynamic. A hybrid mode between the default and
297 --bind-interfaces which copes with dynamically created
298 interfaces.
299
300 A couple of fixes to the build system for Android. Thanks
301 to Metin Kaya for the patches.
302
303 Remove the interface:<interface> argument in --dhcp-range, and
304 the interface argument to --enable-tftp. These were a
305 still-born attempt to allow automatic isolated
306 configuration by libvirt, but have never (to my knowledge)
307 been used, had very strange semantics, and have been
308 superceded by other mechanisms.
309
310 Fixed bug logging filenames when duplicate dhcp-host
311 addresses are found. Thanks to John Hanks for the patch.
312
313 Fix regression in 2.61 which broke caching of CNAME
314 chains. Thanks to Atul Gupta for the bug report.
315
316 Allow the target of a --cname flag to be another --cname.
317
318 Teach DHCPv6 about the RFC 4242 information-refresh-time
319 option, and add parsing if the minutes, hours and days
320 format for options. Thanks to Francois-Xavier Le Bail for
321 the suggestion.
322
323 Allow "w" (for week) as multiplier in lease times, as well
324 as seconds, minutes, hours and days. Álvaro Gámez Machado
325 spotted the ommission.
326
327 Update French translation. Thanks to Gildas Le Nadan.
328
329 Allow a DBus service name to be given with --enable-dbus
330 which overrides the default,
331 uk.org.thekelleys.dnsmasq. Thanks to Mathieu
332 Trudel-Lapierre for the patch.
333
334 Set the "prefix on-link" bit in Router
335 Advertisements. Thanks to Gui Iribarren for the patch.
336
337
338 version 2.62
339 Update German translation. Thanks to Conrad Kostecki.
340
341 Cope with router-solict packets wich don't have a valid
342 source address. Thanks to Vladislav Grishenko for the patch.
343
344 Fixed bug which caused missing periodic router
345 advertisements with some configurations. Thanks to
346 Vladislav Grishenko for the patch.
347
348 Fixed bug which broke DHCPv6/RA with prefix lengths
349 which are not divisible by 8. Thanks to Andre Coetzee
350 for spotting this.
351
352 Fix non-response to router-solicitations when
353 router-advertisement configured, but DHCPv6 not
354 configured. Thanks to Marien Zwart for the patch.
355
356 Add --dns-rr, to allow arbitrary DNS resource records.
357
358 Fixed bug which broke RA scheduling when an interface had
359 two addresses in the same network. Thanks to Jim Bos for
360 his help nailing this.
361
362 version 2.61
363 Re-write interface discovery code on *BSD to use
364 getifaddrs. This is more portable, more straightforward,
365 and allows us to find the prefix length for IPv6
366 addresses.
367
368 Add ra-names, ra-stateless and slaac keywords for DHCPv6.
369 Dnsmasq can now synthesise AAAA records for dual-stack
370 hosts which get IPv6 addresses via SLAAC. It is also now
371 possible to use SLAAC and stateless DHCPv6, and to
372 tell clients to use SLAAC addresses as well as DHCP ones.
373 Thanks to Dave Taht for help with this.
374
375 Add --dhcp-duid to allow DUID-EN uids to be used.
376
377 Explicity send DHCPv6 replies to the correct port, instead
378 of relying on clients to send requests with the correct
379 source address, since at least one client in the wild gets
380 this wrong. Thanks to Conrad Kostecki for help tracking
381 this down.
382
383 Send a preference value of 255 in DHCPv6 replies when
384 --dhcp-authoritative is in effect. This tells clients not
385 to wait around for other DHCP servers.
386
387 Better logging of DHCPv6 options.
388
389 Add --host-record. Thanks to Rob Zwissler for the
390 suggestion.
391
392 Invoke the DHCP script with action "tftp" when a TFTP file
393 transfer completes. The size of the file, address to which
394 it was sent and complete pathname are supplied. Note that
395 version 2.60 introduced some script incompatibilties
396 associated with DHCPv6, and this is a further change. To
397 be safe, scripts should ignore unknown actions, and if
398 not IPv6-aware, should exit if the environment
399 variable DNSMASQ_IAID is set. The use-case for this is
400 to track netboot/install. Suggestion from Shantanu
401 Gadgil.
402
403 Update contrib/port-forward/dnsmasq-portforward to reflect
404 the above.
405
406 Set the environment variable DNSMASQ_LOG_DHCP when running
407 the script id --log-dhcp is in effect, so that script can
408 taylor their logging verbosity. Suggestion from Malte
409 Forkel.
410
411 Arrange that addresses specified with --listen-address
412 work even if there is no interface carrying the
413 address. This is chiefly useful for IPv4 loopback
414 addresses, where any address in 127.0.0.0/8 is a valid
415 loopback address, but normally only 127.0.0.1 appears on
416 the lo interface. Thanks to Mathieu Trudel-Lapierre for
417 the idea and initial patch.
418
419 Fix crash, introduced in 2.60, when a DHCPINFORM is
420 received from a network which has no valid dhcp-range.
421 Thanks to Stephane Glondu for the bug report.
422
423 Add a new DHCP lease time keyword, "deprecated" for
424 --dhcp-range. This is only valid for IPv6, and sets the
425 preffered lease time for both DHCP and RA to zero. The
426 effect is that clients can continue to use the address
427 for existing connections, but new connections will use
428 other addresses, if they exist. This makes hitless
429 renumbering at least possible.
430
431 Fix bug in address6_available() which caused DHCPv6 lease
432 aquisition to fail if more than one dhcp-range in use.
433
434 Provide RDNSS and DNSSL data in router advertisements,
435 using the settings provided for DHCP options
436 option6:domain-search and option6:dns-server.
437
438 Tweak logo/favicon.ico to add some transparency. Thanks to
439 SamLT for work on this.
440
441 Don't cache data from non-recursive nameservers, since it
442 may erroneously look like a valid CNAME to a non-exitant
443 name. Thanks to Ben Winslow for finding this.
444
445 Call SO_BINDTODEVICE on the DHCP socket(s) when doing DHCP
446 on exactly one interface and --bind-interfaces is set. This
447 makes the OpenStack use-case of one dnsmasq per virtual
448 interface work. This is only available on Linux; it's not
449 supported on other platforms. Thanks to Vishvananda Ishaya
450 and the OpenStack team for the suggestion.
451
452 Updated French translation. Thanks to Gildas Le Nadan.
453
454 Give correct from-cache answers to explict CNAME queries.
455 Thanks to Rob Zwissler for spotting this.
456
457 Add --tftp-lowercase option. Thanks to Oliver Rath for the
458 patch.
459
460 Ensure that the DBus DhcpLeaseUpdated events are generated
461 when a lease goes through INIT_REBOOT state, even if the
462 dhcp-script is not in use. Thanks to Antoaneta-Ecaterina
463 Ene for the patch.
464
465 Fix failure of TFTP over IPv4 on OpenBSD platform. Thanks
466 to Brad Smith for spotting this.
467
468
469 version 2.60
470 Fix compilation problem in Mac OS X Lion. Thanks to Olaf
471 Flebbe for the patch.
472
473 Fix DHCP when using --listen-address with an IP address
474 which is not the primary address of an interface.
475
476 Add --dhcp-client-update option.
477
478 Add Lua integration. Dnsmasq can now execute a DHCP
479 lease-change script written in Lua. This needs to be
480 enabled at compile time by setting HAVE_LUASCRIPT in
481 src/config.h or running "make COPTS=-DHAVE_LUASCRIPT"
482 Thanks to Jan-Piet Mens for the idea and proof-of-concept
483 implementation.
484
485 Tidied src/config.h to distinguish between
486 platform-dependent compile-time options which are selected
487 automatically, and builder-selectable compile time
488 options. Document the latter better, and describe how to
489 set them from the make command line.
490
491 Tidied up IPPROTO_IP/SOL_IP (and IPv6 equivalent)
492 confusion. IPPROTO_IP works everywhere now.
493
494 Set TOS on DHCP sockets, this improves things on busy
495 wireless networks. Thanks to Dave Taht for the patch.
496
497 Determine VERSION automatically based on git magic:
498 release tags or hash values.
499
500 Improve start-up speed when reading large hosts files
501 containing many distinct addresses.
502
503 Fix problem if dnsmasq is started without the stdin,
504 stdout and stderr file descriptors open. This can manifest
505 itself as 100% CPU use. Thanks to Chris Moore for finding
506 this.
507
508 Fix shell-scripting bug in bld/pkg-wrapper. Thanks to
509 Mark Mitchell for the patch.
510
511 Allow the TFP server or boot server in --pxe-service, to
512 be a domain name instead of an IP address. This allows for
513 round-robin to multiple servers, in the same way as
514 --dhcp-boot. A good suggestion from Cristiano Cumer.
515
516 Support BUILDDIR variable in the Makefile. Allows builds
517 for multiple archs from the same source tree with eg.
518 make BUILDDIR=linux (relative to dnsmasq tree)
519 make BUILDDIR=/tmp/openbsd (absolute path)
520 If BUILDDIR is not set, compilation happens in the src
521 directory, as before. Suggestion from Mark Mitchell.
522
523 Support DHCPv6. Support is there for the sort of things
524 the existing v4 server does, including tags, options,
525 static addresses and relay support. Missing is prefix
526 delegation, which is probably not required in the dnsmasq
527 niche, and an easy way to accept prefix delegations from
528 an upstream DHCPv6 server, which is. Future plans include
529 support for DHCPv6 router option and MAC address option
530 (to make selecting clients by MAC address work like IPv4).
531 These will be added as the standards mature.
532 This code has been tested, but this is the first release,
533 so don't bet the farm on it just yet. Many thanks to all
534 testers who have got it this far.
535
536 Support IPv6 router advertisements. This is a
537 simple-minded implementation, aimed at providing the
538 vestigial RA needed to go alongside IPv6. Is picks up
539 configuration from the DHCPv6 conf, and should just need
540 enabling with --enable-ra.
541
542 Fix long-standing wrinkle with --localise-queries that
543 could result in wrong answers when DNS packets arrive
544 via an interface other than the expected one. Thanks to
545 Lorenzo Milesi and John Hanks for spotting this one.
546
547 Update French translation. Thanks to Gildas Le Nadan.
548
549 Update Polish translation. Thanks to Jan Psota.
550
551
552 version 2.59
553 Fix regression in 2.58 which caused failure to start up
554 with some combinations of dnsmasq config and IPv6 kernel
555 network config. Thanks to Brielle Bruns for the bug
556 report.
557
558 Improve dnsmasq's behaviour when network interfaces are
559 still doing duplicate address detection (DAD). Previously,
560 dnsmasq would wait up to 20 seconds at start-up for the
561 DAD state to terminate. This is broken for bridge
562 interfaces on recent Linux kernels, which don't start DAD
563 until the bridge comes up, and so can take arbitrary
564 time. The new behaviour lets dnsmasq poll for an arbitrary
565 time whilst providing service on other interfaces. Thanks
566 to Stephen Hemminger for pointing out the problem.
567
568
569 version 2.58
570 Provide a definition of the SA_SIZE macro where it's
571 missing. Fixes build failure on openBSD.
572
573 Don't include a zero terminator at the end of messages
574 sent to /dev/log when /dev/log is a datagram socket.
575 Thanks to Didier Rabound for spotting the problem.
576
577 Add --dhcp-sequential-ip flag, to force allocation of IP
578 addresses in ascending order. Note that the default
579 pseudo-random mode is in general better but some
580 server-deployment applications need this.
581
582 Fix problem where a server-id of 0.0.0.0 is sent to a
583 client when a dhcp-relay is in use if a client renews a
584 lease after dnsmasq restart and before any clients on the
585 subnet get a new lease. Thanks to Mike Ruiz for assistance
586 in chasing this one down.
587
588 Don't return NXDOMAIN to an AAAA query if we have CNAME
589 which points to an A record only: NODATA is the correct
590 reply in this case. Thanks to Tom Fernandes for spotting
591 the problem.
592
593 Relax the need to supply a netmask in --dhcp-range for
594 networks which use a DHCP relay. Whilst this is still
595 desireable, in the absence of a netmask dnsmasq will use
596 a default based on the class (A, B, or C) of the address.
597 This should at least remove a cause of mysterious failure
598 for people using RFC1918 addresses and relays.
599
600 Add support for Linux conntrack connection marking. If
601 enabled with --conntrack, the connection mark for incoming
602 DNS queries will be copied to the outgoing connections
603 used to answer those queries. This allows clever firewall
604 and accounting stuff. Only available if dnsmasq is
605 compiled with HAVE_CONNTRACK and adds a dependency on
606 libnetfilter-conntrack. Thanks to Ed Wildgoose for the
607 initial idea, testing and sponsorship of this function.
608
609 Provide a sane error message when someone attempts to
610 match a tag in --dhcp-host.
611
612 Tweak the behaviour of --domain-needed, to avoid problems
613 with recursive nameservers downstream of dnsmasq. The new
614 behaviour only stops A and AAAA queries, and returns
615 NODATA rather than NXDOMAIN replies.
616
617 Efficiency fix for very large DHCP configurations, thanks
618 to James Gartrell and Mike Ruiz for help with this.
619
620 Allow the TFTP-server address in --dhcp-boot to be a
621 domain-name which is looked up in /etc/hosts. This can
622 give multiple IP addresses which are used round-robin,
623 thus doing TFTP server load-balancing. Thanks to Sushil
624 Agrawal for the patch.
625
626 When two tagged dhcp-options for a particular option
627 number are both valid, use the one which is valid without
628 a tag from the dhcp-range. Allows overriding of the value
629 of a DHCP option for a particular host as well as
630 per-network values. So
631 --dhcp-range=set:interface1,......
632 --dhcp-host=set:myhost,.....
633 --dhcp-option=tag:interface1,option:nis-domain,"domain1"
634 --dhcp-option=tag:myhost,option:nis-domain,"domain2"
635 will set the NIS-domain to domain1 for hosts in the range, but
636 override that to domain2 for a particular host.
637
638 Fix bug which resulted in truncated files and timeouts for
639 some TFTP transfers. The bug only occurs with netascii
640 transfers and needs an unfortunate relationship between
641 file size, blocksize and the number of newlines in the
642 last block before it manifests itself. Many thanks to
643 Alkis Georgopoulos for spotting the problem and providing
644 a comprehensive test-case.
645
646 Fix regression in TFTP server on *BSD platforms introduced
647 in version 2.56, due to confusion with sockaddr
648 length. Many thanks to Loic Pefferkorn for finding this.
649
650 Support scope-ids in IPv6 addresses of nameservers from
651 /etc/resolv.conf and in --server options. Eg
652 nameserver fe80::202:a412:4512:7bbf%eth0 or
653 server=fe80::202:a412:4512:7bbf%eth0. Thanks to
654 Michael Stapelberg for the suggestion.
655
656 Update Polish translation, thanks to Jan Psota.
657
658 Update French translation. Thanks to Gildas Le Nadan.
659
660
661 version 2.57
662 Add patches to allow build under Android.
663
664 Provide our own header for the DNS protocol, rather than
665 relying on arpa/nameser.h. This has proved more or less
666 defective over the years and the final straw is that it's
667 effectively empty on Android.
668
669 Fix regression in 2.56 which caused hex constants in
670 configuration to be rejected if they contain the '*'
671 wildcard.
672
673 Correct wrong casts of arguments to ctype.h functions,
674 isdigit(), isxdigit() etc. Thanks to Matthias Andree for
675 spotting this.
676
677 Allow build with IDN support independently from i18n.
678 IDN support continues to be included automatically
679 when i18n is included.
680 'make COPTS=-DHAVE_IDN' is the magic incantation.
681
682 Modify check on extraneous command line junk (added in
683 2.56) so that it doesn't complain about extra _empty_
684 arguments. Otherwise this breaks libvirt.
685
686
687 version 2.56
688 Add a patch to allow dnsmasq to get interface names right in a
689 Solaris zone. Thanks to Dj Padzensky for this.
690
691 Improve data-type parsing heuristics so that
692 --dhcp-option=option:domain-search,.
693 treats the value as a string and not an IP address.
694 Thanks to Clemens Fischer for spotting that.
695
696 Add IPv6 support to the TFTP server. Many thanks to Jan
697 'RedBully' Seiffert for the patches.
698
699 Log DNS queries at level LOG_INFO, rather then
700 LOG_DEBUG. This makes things consistent with DHCP
701 logging. Thanks to Adam Pribyl for spotting the problem.
702
703 Ensure that dnsmasq terminates cleanly when using
704 --syslog-async even if it cannot make a connection to the
705 syslogd.
706
707 Add --add-mac option. This is to support currently
708 experimental DNS filtering facilities. Thanks to Benjamin
709 Petrin for the orignal patch.
710
711 Fix bug which meant that tags were ignored in dhcp-range
712 configuration specifying PXE-proxy service. Thanks to
713 Cristiano Cumer for spotting this.
714
715 Raise an error if there is extra junk, not part of an
716 option, on the command line.
717
718 Flag a couple of log messages in cache.c as coming from
719 the DHCP subsystem. Thanks to Olaf Westrik for the patch.
720
721 Omit timestamps from logs when a) logging to stderr and
722 b) --keep-in-forground is set. The logging facility on the
723 other end of stderr can be assumned to supply them. Thanks
724 to John Hallam for the patch.
725
726 Don't complain about strings longer than 255 characters in
727 --txt-record, just split the long strings into 255
728 character chunks instead.
729
730 Fix crash on double-free. This bug can only happen when
731 dhcp-script is in use and then only in rare circumstances
732 triggered by high DHCP transaction rate and a slow
733 script. Thanks to Ferenc Wagner for finding the problem.
734
735 Only log that a file has been sent by TFTP after the
736 transfer has completed succesfully.
737
738 A good suggestion from Ferenc Wagner: extend
739 the --domain option to allow this sort of thing:
740 --domain=thekelleys.org.uk,192.168.0.0/24,local
741 which automatically creates
742 --local=/thekelleys.org.uk/
743 --local=/0.168.192.in-addr.arpa/
744
745 Tighten up syntax checking of hex contants in the config
746 file. Thanks to Fred Damen for spotting this.
747
748 Add dnsmasq logo/icon, contributed by Justin Swift. Many
749 thanks for that.
750
751 Never cache DNS replies which have the 'cd' bit set, or
752 which result from queries forwarded with the 'cd' bit
753 set. The 'cd' bit instructs a DNSSEC validating server
754 upstream to ignore signature failures and return replies
755 anyway. Without this change it's possible to pollute the
756 dnsmasq cache with bad data by making a query with the
757 'cd' bit set and subsequent queries would return this data
758 without its being marked as suspect. Thanks to Anders
759 Kaseorg for pointing out this problem.
760
761 Add --proxy-dnssec flag, for compliance with RFC
762 4035. Dnsmasq will now clear the 'ad' bit in answers returned
763 from upstream validating nameservers unless this option is
764 set.
765
766 Allow a filename of "-" for --conf-file to read
767 stdin. Suggestion from Timothy Redaelli.
768
769 Rotate the order of SRV records in replies, to provide
770 round-robin load balancing when all the priorities are
771 equal. Thanks to Peter McKinney for the suggestion.
772
773 Edit
774 contrib/MacOSX-launchd/uk.org.thekelleys.dnsmasq.plist
775 so that it doesn't log all queries to a file by
776 default. Thanks again to Peter McKinney.
777
778 By default, setting an IPv4 address for a domain but not
779 an IPv6 address causes dnsmasq to return
780 an NODATA reply for IPv6 (or vice-versa). So
781 --address=/google.com/1.2.3.4 stops IPv6 queries for
782 *google.com from being forwarded. Make it possible to
783 override this behaviour by defining the sematics if the
784 same domain appears in both --server and --address.
785 In that case, the --address has priority for the address
786 family in which is appears, but the --server has priority
787 of the address family which doesn't appear in --adddress
788 So:
789 --address=/google.com/1.2.3.4
790 --server=/google.com/#
791 will return 1.2.3.4 for IPv4 queries for *.google.com but
792 forward IPv6 queries to the normal upstream nameserver.
793 Similarly when setting an IPv6 address
794 only this will allow forwarding of IPv4 queries. Thanks to
795 William for pointing out the need for this.
796
797 Allow more than one --dhcp-optsfile and --dhcp-hostsfile
798 and make them understand directories as arguments in the
799 same way as --addn-hosts. Suggestion from John Hanks.
800
801 Ignore rebinding requests for leases we don't know
802 about. Rebind is broadcast, so we might get to overhear a
803 request meant for another DHCP server. NAKing this is
804 wrong. Thanks to Brad D'Hondt for assistance with this.
805
806 Fix cosmetic bug which produced strange output when
807 dumping cache statistics with some configurations. Thanks
808 to Fedor Kozhevnikov for spotting this.
809
810
811 version 2.55
812 Fix crash when /etc/ethers is in use. Thanks to
813 Gianluigi Tiesi for finding this.
814
815 Fix crash in netlink_multicast(). Thanks to Arno Wald for
816 finding this one.
817
818 Allow the empty domain "." in dhcp domain-search (119)
819 options.
820
821
822 version 2.54
823 There is no version 2.54 to avoid confusion with 2.53,
824 which incorrectly identifies itself as 2.54.
825
826
827 version 2.53
828 Fix failure to compile on Debian/kFreeBSD. Thanks to
829 Axel Beckert and Petr Salinger.
830
831 Fix code to avoid scary strict-aliasing warnings
832 generated by gcc 4.4.
833
834 Added FAQ entry warning about DHCP failures with Vista
835 when firewalls block 255.255.255.255.
836
837 Fixed bug which caused bad things to happen if a
838 resolv.conf file which exists is subsequently removed.
839 Thanks to Nikolai Saoukh for the patch.
840
841 Rationalised the DHCP tag system. Every configuration item
842 which can set a tag does so by adding "set:<tag>" and
843 every configuration item which is conditional on a tag is
844 made so by "tag:<tag>". The NOT operator changes to '!',
845 which is a bit more intuitive too. Dhcp-host directives
846 can set more than one tag now. The old '#' NOT,
847 "net:" prefix and no-prefixes are still honoured, so
848 no existing config file needs to be changed, but
849 the documentation and new-style config files should be
850 much less confusing.
851
852 Added --tag-if to allow boolean operations on tags.
853 This allows complicated logic to be clearer and more
854 general. A great suggestion from Richard Voigt.
855
856 Add broadcast/unicast information to DHCP logging.
857
858 Allow --dhcp-broadcast to be unconditional.
859
860 Fixed incorrect behaviour with NOT <tag> conditionals in
861 dhcp-options. Thanks to Max Turkewitz for assistance
862 finding this.
863
864 If we send vendor-class encapsulated options based on the
865 vendor-class supplied by the client, and no explicit
866 vendor-class option is given, echo back the vendor-class
867 from the client.
868
869 Fix bug which stopped dnsmasq from matching both a
870 circuitid and a remoteid. Thanks to Ignacio Bravo for
871 finding this.
872
873 Add --dhcp-proxy, which makes it possible to configure
874 dnsmasq to use a DHCP relay agent as a full proxy, with
875 all DHCP messages passing through the proxy. This is
876 useful if the relay adds extra information to the packets
877 it forwards, but cannot be configured with the RFC 5107
878 server-override option.
879
880 Added interface:<iface name> part to dhcp-range. The
881 semantics of this are very odd at first sight, but it
882 allows a single line of the form
883 dhcp-range=interface:virt0,192.168.0.4,192.168.0.200
884 to be added to dnsmasq configuration which then supplies
885 DHCP and DNS services to that interface, without affecting
886 what services are supplied to other interfaces and
887 irrespective of the existance or lack of
888 interface=<interface>
889 lines elsewhere in the dnsmasq configuration. The idea is
890 that such a line can be added automatically by libvirt
891 or equivalent systems, without disturbing any manual
892 configuration.
893
894 Similarly to the above, allow --enable-tftp=<interface>
895
896 Allow a TFTP root to be set separately for requests via
897 different interfaces, --tftp-root=<path>,<interface>
898
899 Correctly handle and log clashes between CNAMES and
900 DNS names being given to DHCP leases. This fixes a bug
901 which caused nonsense IP addresses to be logged. Thanks to
902 Sergei Zhirikov for finding and analysing the problem.
903
904 Tweak flush_log so as to avoid leaving the log
905 file in non-blocking mode. O_NONBLOCK is a property of the
906 file, not the process/descriptor.
907
908 Fix contrib/Solaris10/create_package
909 (/usr/man -> /usr/share/man) Thanks to Vita Batrla.
910
911 Fix a problem where, if a client got a lease, then went
912 to another subnet and got another lease, then moved back,
913 it couldn't resume the old lease, but would instead get
914 a new address. Thanks to Leonardo Rodrigues for spotting
915 this and testing the fix.
916
917 Fix weird bug which sometimes omitted certain characters
918 from the start of quoted strings in dhcp-options. Thanks
919 to Dayton Turner for spotting the problem.
920
921 Add facility to redirect some domains to the standard
922 upstream servers: this allows something like
923 --server=/google.com/1.2.3.4 --server=/www.google.com/#
924 which will send queries for *.google.com to 1.2.3.4,
925 except *www.google.com which will be forwarded as usual.
926 Thanks to AJ Weber for prompting this addition.
927
928 Improve the hash-algorithm used to generate IP addresses
929 from MAC addresses during initial DHCP address
930 allocation. This improves performance when large numbers
931 of hosts with similar MAC addresses all try and get an IP
932 address at the same time. Thanks to Paul Smith for his
933 work on this.
934
935 Tweak DHCP code so that --bridge-interface can be used to
936 select which IP alias of an interface should be used for
937 DHCP purposes on Linux. If eth0 has an alias eth0:dhcp
938 then adding --bridge-interface=eth0:dhcp,eth0 will use
939 the address of eth0:dhcp to determine the correct subnet
940 for DHCP address allocation. Thanks to Pawel Golaszewski
941 for prompting this and Eric Cooper for further testing.
942
943 Add --dhcp-generate-names. Suggestion by Ferenc Wagner.
944
945 Tweak DNS server selection algorithm when there is more
946 than one server available for a domain, eg.
947 --server=/mydomain/1.1.1.1
948 --server=/mydomain/2.2.2.2
949 Thanks to Alberto Cuesta-Canada for spotting a weakness
950 here.
951
952 Add --max-ttl. Thanks to Fredrik Ringertz for the patch.
953
954 Allow --log-facility=- to force all logging to
955 stderr. Suggestion from Clemens Fischer.
956
957 Fix regression which caused configuration like
958 --address=/.domain.com/1.2.3.4 to be rejected. The dot to the
959 left of the domain has been implied and not required for a
960 long time, but it should be accepted for backward
961 compatibility. Thanks to Andrew Burcin for spotting this.
962
963 Add --rebind-domain-ok and --rebind-localhost-ok.
964 Suggestion from Clemens Fischer.
965
966 Log replies to queries of type TXT, when --log-queries
967 is set.
968
969 Fix compiler warnings when compiled with -DNO_DHCP. Thanks
970 to Shantanu Gadgil for the patch.
971
972 Updated French translation. Thanks to Gildas Le Nadan.
973
974 Updated Polish translation. Thanks to Jan Psota.
975
976 Updated German translation. Thanks to Matthias Andree.
977
978 Added contrib/static-arp, thanks to Darren Hoo.
979
980 Fix corruption of the domain when a name from /etc/hosts
981 overrides one supplied by a DHCP client. Thanks to Fedor
982 Kozhevnikov for spotting the problem.
983
984 Updated Spanish translation. Thanks to Chris Chatham.
985
986
987 version 2.52
988 Work around a Linux kernel bug which insists that the
989 length of the option passed to setsockopt must be at least
990 sizeof(int) bytes, even if we're calling SO_BINDTODEVICE
991 and the device name is "lo". Note that this is fixed
992 in kernel 2.6.31, but the workaround is harmless and
993 allows earlier kernels to be used. Also fix dnsmasq
994 bug which reported the wrong address when this failed.
995 Thanks to Fedor for finding this.
996
997 The API for IPv6 PKTINFO changed around Linux kernel
998 2.6.14. Workaround the case where dnsmasq is compiled
999 against newer headers, but then run on an old kernel:
1000 necessary for some *WRT distros.
1001
1002 Re-read the set of network interfaces when re-loading
1003 /etc/resolv.conf if --bind-interfaces is not set. This
1004 handles the case that loopback interfaces do not exist
1005 when dnsmasq is first started.
1006
1007 Tweak the PXE code to support port 4011. This should
1008 reduce broadcasts and make things more reliable when other
1009 servers are around. It also improves inter-operability
1010 with certain clients.
1011
1012 Make a pxe-service configuration with no filename or boot
1013 service type legal: this does a local boot. eg.
1014 pxe-service=x86PC, "Local boot"
1015
1016 Be more conservative in detecting "A for A"
1017 queries. Dnsmasq checks if the name in a type=A query looks
1018 like a dotted-quad IP address and answers the query itself
1019 if so, rather than forwarding it. Previously dnsmasq
1020 relied in the library function inet_addr() to convert
1021 addresses, and that will accept some things which are
1022 confusing in this context, like 1.2.3 or even just
1023 1234. Now we only do A for A processing for four decimal
1024 numbers delimited by dots.
1025
1026 A couple of tweaks to fix compilation on Solaris. Thanks
1027 to Joel Macklow for help with this.
1028
1029 Another Solaris compilation tweak, needed for Solaris
1030 2009.06. Thanks to Lee Essen for that.
1031
1032 Added extract packaging stuff from Lee Essen to
1033 contrib/Solaris10.
1034
1035 Increased the default limit on number of leases to 1000
1036 (from 150). This is mainly a defence against DoS attacks,
1037 and for the average "one for two class C networks"
1038 installation, IP address exhaustion does that just as
1039 well. Making the limit greater than the number of IP
1040 addresses available in such an installation removes a
1041 surprise which otherwise can catch people out.
1042
1043 Removed extraneous trailing space in the value of the
1044 DNSMASQ_TIME_REMAINING DNSMASQ_LEASE_LENGTH and
1045 DNSMASQ_LEASE_EXPIRES environment variables. Thanks to
1046 Gildas Le Nadan for spotting this.
1047
1048 Provide the network-id tags for a DHCP transaction to
1049 the lease-change script in the environment variable
1050 DNSMASQ_TAGS. A good suggestion from Gildas Le Nadan.
1051
1052 Add support for RFC3925 "Vendor-Identifying Vendor
1053 Options". The syntax looks like this:
1054 --dhcp-option=vi-encap:<enterprise number>, .........
1055
1056 Add support to --dhcp-match to allow matching against
1057 RFC3925 "Vendor-Identifying Vendor Classes". The syntax
1058 looks like this:
1059 --dhcp-match=tag,vi-encap<enterprise number>, <value>
1060
1061 Add some application specific code to assist in
1062 implementing the Broadband forum TR069 CPE-WAN
1063 specification. The details are in contrib/CPE-WAN/README
1064
1065 Increase the default DNS packet size limit to 4096, as
1066 recommended by RFC5625 section 4.4.3. This can be
1067 reconfigured using --edns-packet-max if needed. Thanks to
1068 Francis Dupont for pointing this out.
1069
1070 Rewrite query-ids even for TSIG signed packets, since
1071 this is allowed by RFC5625 section 4.5.
1072
1073 Use getopt_long by default on OS X. It has been supported
1074 since version 10.3.0. Thanks to Arek Dreyer for spotting
1075 this.
1076
1077 Added up-to-date startup configuration for MacOSX/launchd
1078 in contrib/MacOSX-launchd. Thanks to Arek Dreyer for
1079 providing this.
1080
1081 Fix link error when including Dbus but excluding DHCP.
1082 Thanks to Oschtan for the bug report.
1083
1084 Updated French translation. Thanks to Gildas Le Nadan.
1085
1086 Updated Polish translation. Thanks to Jan Psota.
1087
1088 Updated Spanish translation. Thanks to Chris Chatham.
1089
1090 Fixed confusion about domains, when looking up DHCP hosts
1091 in /etc/hosts. This could cause spurious "Ignoring
1092 domain..." messages. Thanks to Fedor Kozhevnikov for
1093 finding and analysing the problem.
1094
1095
1096 version 2.51
1097 Add support for internationalised DNS. Non-ASCII characters
1098 in domain names found in /etc/hosts, /etc/ethers and
1099 /etc/dnsmasq.conf will be correctly handled by translation to
1100 punycode, as specified in RFC3490. This function is only
1101 available if dnsmasq is compiled with internationalisation
1102 support, and adds a dependency on GNU libidn. Without i18n
1103 support, dnsmasq continues to be compilable with just
1104 standard tools. Thanks to Yves Dorfsman for the
1105 suggestion.
1106
1107 Add two more environment variables for lease-change scripts:
1108 First, DNSMASQ_SUPPLIED_HOSTNAME; this is set to the hostname
1109 supplied by a client, even if the actual hostname used is
1110 over-ridden by dhcp-host or dhcp-ignore-names directives.
1111 Also DNSMASQ_RELAY_ADDRESS which gives the address of
1112 a DHCP relay, if used.
1113 Suggestions from Michael Rack.
1114
1115 Fix regression which broke echo of relay-agent
1116 options. Thanks to Michael Rack for spotting this.
1117
1118 Don't treat option 67 as being interchangeable with
1119 dhcp-boot parameters if it's specified as
1120 dhcp-option-force.
1121
1122 Make the code to call scripts on lease-change compile-time
1123 optional. It can be switched off by editing src/config.h
1124 or building with "make COPTS=-DNO_SCRIPT".
1125
1126 Make the TFTP server cope with filenames from Windows/DOS
1127 which use '\' as pathname separator. Thanks to Ralf for
1128 the patch.
1129
1130 Updated Polish translation. Thanks to Jan Psota.
1131
1132 Warn if an IP address is duplicated in /etc/ethers. Thanks
1133 to Felix Schwarz for pointing this out.
1134
1135 Teach --conf-dir to take an option list of file suffices
1136 which will be ignored when scanning the directory. Useful
1137 for backup files etc. Thanks to Helmut Hullen for the
1138 suggestion.
1139
1140 Add new DHCP option named tftpserver-address, which
1141 corresponds to the third argument of dhcp-boot. This
1142 allows the complete functionality of dhcp-boot to be
1143 replicated with dhcp-option. Useful when using
1144 dhcp-optsfile.
1145
1146 Test which upstream nameserver to use every 10 seconds
1147 or 50 queries and not just when a query times out and
1148 is retried. This should improve performance when there
1149 is a slow nameserver in the list. Thanks to Joe for the
1150 suggestion.
1151
1152 Don't do any PXE processing, even for clients with the
1153 correct vendorclass, unless at least one pxe-prompt or
1154 pxe-service option is given. This stops dnsmasq
1155 interfering with proxy PXE subsystems when it is just
1156 the DHCP server. Thanks to Spencer Clark for spotting this.
1157
1158 Limit the blocksize used for TFTP transfers to a value
1159 which avoids packet fragmentation, based on the MTU of the
1160 local interface. Many netboot ROMs can't cope with
1161 fragmented packets.
1162
1163 Honour dhcp-ignore configuration for PXE and proxy-PXE
1164 requests. Thanks to Niels Basjes for the bug report.
1165
1166 Updated French translation. Thanks to Gildas Le Nadan.
1167
1168
1169 version 2.50
1170 Fix security problem which allowed any host permitted to
1171 do TFTP to possibly compromise dnsmasq by remote buffer
1172 overflow when TFTP enabled. Thanks to Core Security
1173 Technologies and Iván Arce, Pablo Hernán Jorge, Alejandro
1174 Pablo Rodriguez, Martín Coco, Alberto Soliño Testa and
1175 Pablo Annetta. This problem has Bugtraq id: 36121
1176 and CVE: 2009-2957
1177
1178 Fix a problem which allowed a malicious TFTP client to
1179 crash dnsmasq. Thanks to Steve Grubb at Red Hat for
1180 spotting this. This problem has Bugtraq id: 36120 and
1181 CVE: 2009-2958
1182
1183
1184 version 2.49
1185 Fix regression in 2.48 which disables the lease-change
1186 script. Thanks to Jose Luis Duran for spotting this.
1187
1188 Log TFTP "file not found" errors. These were not logged,
1189 since a normal PXELinux boot generates many of them, but
1190 the lack of the messages seems to be more confusing than
1191 routinely seeing them when there is no real error.
1192
1193 Update Spanish translation. Thanks to Chris Chatham.
1194
1195
1196 version 2.48
1197 Archived the extensive, backwards, changelog to
1198 CHANGELOG.archive. The current changelog now runs from
1199 version 2.43 and runs conventionally.
1200
1201 Fixed bug which broke binding of servers to physical
1202 interfaces when interface names were longer than four
1203 characters. Thanks to MURASE Katsunori for the patch.
1204
1205 Fixed netlink code to check that messages come from the
1206 correct source, and not another userspace process. Thanks
1207 to Steve Grubb for the patch.
1208
1209 Maintainability drive: removed bug and missing feature
1210 workarounds for some old platforms. Solaris 9, OpenBSD
1211 older than 4.1, Glibc older than 2.2, Linux 2.2.x and
1212 DBus older than 1.1.x are no longer supported.
1213
1214 Don't read included configuration files more than once:
1215 allows complex configuration structures without problems.
1216
1217 Mark log messages from the various subsystems in dnsmasq:
1218 messages from the DHCP subsystem now have the ident string
1219 "dnsmasq-dhcp" and messages from TFTP have ident
1220 "dnsmasq-tftp". Thanks to Olaf Westrik for the patch.
1221
1222 Fix possible infinite DHCP protocol loop when an IP
1223 address nailed to a hostname (not a MAC address) and a
1224 host sometimes provides the name, sometimes not.
1225
1226 Allow --addn-hosts to take a directory: all the files
1227 in the directory are read. Thanks to Phil Cornelius for
1228 the suggestion.
1229
1230 Support --bridge-interface on all platforms, not just BSD.
1231
1232 Added support for advanced PXE functions. It's now
1233 possible to define a prompt and menu options which will
1234 be displayed when a client PXE boots. It's also possible to
1235 hand-off booting to other boot servers. Proxy-DHCP, where
1236 dnsmasq just supplies the PXE information and another DHCP
1237 server does address allocation, is also allowed. See the
1238 --pxe-prompt and --pxe-service keywords. Thanks to
1239 Alkis Georgopoulos for the suggestion and Guilherme Moro
1240 and Michael Brown for assistance.
1241
1242 Improvements to DHCP logging. Thanks to Tom Metro for
1243 useful suggestions.
1244
1245 Add ability to build dnsmasq without DHCP support. To do
1246 this, edit src/config.h or build with
1247 "make COPTS=-DNO_DHCP". Thanks to Mahavir Jain for the patch.
1248
1249 Added --test command-line switch - syntax check
1250 configuration files only.
1251
1252 Updated French translation. Thanks to Gildas Le Nadan.
1253
1254
1255 version 2.47
1256 Updated French translation. Thanks to Gildas Le Nadan.
1257
1258 Fixed interface enumeration code to work on NetBSD
1259 5.0. Thanks to Roy Marples for the patch.
1260
1261 Updated config.h to use the same location for the lease
1262 file on NetBSD as the other *BSD variants. Also allow
1263 LEASEFILE and CONFFILE symbols to be overriden in CFLAGS.
1264
1265 Handle duplicate address detection on IPv6 more
1266 intelligently. In IPv6, an interface can have an address
1267 which is not usable, because it is still undergoing DAD
1268 (such addresses are marked "tentative"). Attempting to
1269 bind to an address in this state returns an error,
1270 EADDRNOTAVAIL. Previously, on getting such an error,
1271 dnsmasq would silently abandon the address, and never
1272 listen on it. Now, it retries once per second for 20
1273 seconds before generating a fatal error. 20 seconds should
1274 be long enough for any DAD process to complete, but can be
1275 adjusted in src/config.h if necessary. Thanks to Martin
1276 Krafft for the bug report.
1277
1278 Add DBus introspection. Patch from Jeremy Laine.
1279
1280 Update Dbus configuration file. Patch from Colin Walters.
1281 Fix for this bug:
1282 http://bugs.freedesktop.org/show_bug.cgi?id=18961
1283
1284 Support arbitrarily encapsulated DHCP options, suggestion
1285 and initial patch from Samium Gromoff. This is useful for
1286 (eg) gPXE, which expect all its private options to be
1287 encapsulated inside a single option 175. So, eg,
1288
1289 dhcp-option = encap:175, 190, "iscsi-client0"
1290 dhcp-option = encap:175, 191, "iscsi-client0-secret"
1291
1292 will provide iSCSI parameters to gPXE.
1293
1294 Enhance --dhcp-match to allow testing of the contents of a
1295 client-sent option, as well as its presence. This
1296 application in mind for this is RFC 4578
1297 client-architecture specifiers, but it's generally useful.
1298 Joey Korkames suggested the enhancement.
1299
1300 Move from using the IP_XMIT_IF ioctl to IP_BOUND_IF on
1301 OpenSolaris. Thanks to Bastian Machek for the heads-up.
1302
1303 No longer complain about blank lines in
1304 /etc/ethers. Thanks to Jon Nelson for the patch.
1305
1306 Fix binding of servers to physical devices, eg
1307 --server=/domain/1.2.3.4@eth0 which was broken from 2.43
1308 onwards unless --query-port=0 set. Thanks to Peter Naulls
1309 for the bug report.
1310
1311 Reply to DHCPINFORM requests even when the supplied ciaddr
1312 doesn't fall in any dhcp-range. In this case it's not
1313 possible to supply a complete configuration, but
1314 individually-configured options (eg PAC) may be useful.
1315
1316 Allow the source address of an alias to be a range:
1317 --alias=192.168.0.0,10.0.0.0,255.255.255.0 maps the whole
1318 subnet 192.168.0.0->192.168.0.255 to 10.0.0.0->10.0.0.255,
1319 as before.
1320 --alias=192.168.0.10-192.168.0.40,10.0.0.0,255.255.255.0
1321 maps only the 192.168.0.10->192.168.0.40 region. Thanks to
1322 Ib Uhrskov for the suggestion.
1323
1324 Don't dynamically allocate DHCP addresses which may break
1325 Windows. Addresses which end in .255 or .0 are broken in
1326 Windows even when using supernetting.
1327 --dhcp-range=192.168.0.1,192.168.1.254,255,255,254.0 means
1328 192.168.0.255 is a valid IP address, but not for Windows.
1329 See Microsoft KB281579. We therefore no longer allocate
1330 these addresses to avoid hard-to-diagnose problems.
1331
1332 Update Polish translation. Thanks to Jan Psota.
1333
1334 Delete the PID-file when dnsmasq shuts down. Note that by
1335 this time, dnsmasq is normally not running as root, so
1336 this will fail if the PID-file is stored in a root-owned
1337 directory; such failure is silently ignored. To take
1338 advantage of this feature, the PID-file must be stored in a
1339 directory owned and write-able by the user running
1340 dnsmasq.
1341
1342
1343 version 2.46
1344 Allow --bootp-dynamic to take a netid tag, so that it may
1345 be selectively enabled. Thanks to Olaf Westrik for the
1346 suggestion.
1347
1348 Remove ISC-leasefile reading code. This has been
1349 deprecated for a long time, and last time I removed it, it
1350 ended up going back by request of one user. This time,
1351 it's gone for good; otherwise it would need to be
1352 re-worked to support multiple domains (see below).
1353
1354 Support DHCP clients in multiple DNS domains. This is a
1355 long-standing request. Clients are assigned to a domain
1356 based in their IP address.
1357
1358 Add --dhcp-fqdn flag, which changes behaviour if DNS names
1359 assigned to DHCP clients. When this is set, there must be
1360 a domain associated with each client, and only
1361 fully-qualified domain names are added to the DNS. The
1362 advantage is that the only the FQDN needs to be unique,
1363 so that two or more DHCP clients can share a hostname, as
1364 long as they are in different domains.
1365
1366 Set environment variable DNSMASQ_DOMAIN when invoking
1367 lease-change script. This may be useful information to
1368 have now that it's variable.
1369
1370 Tighten up data-checking code for DNS packet
1371 handling. Thanks to Steve Dodd who found certain illegal
1372 packets which could crash dnsmasq. No memory overwrite was
1373 possible, so this is not a security issue beyond the DoS
1374 potential.
1375
1376 Update example config dhcp option 47, the previous
1377 suggestion generated an illegal, zero-length,
1378 option. Thanks to Matthias Andree for finding this.
1379
1380 Rewrite hosts-file reading code to remove the limit of
1381 1024 characters per line. John C Meuser found this.
1382
1383 Create a net-id tag with the name of the interface on
1384 which the DHCP request was received.
1385
1386 Fixed minor memory leak in DBus code, thanks to Jeremy
1387 Laine for the patch.
1388
1389 Emit DBus signals as the DHCP lease database
1390 changes. Thanks to Jeremy Laine for the patch.
1391
1392 Allow for more that one MAC address in a dhcp-host
1393 line. This configuration tells dnsmasq that it's OK to
1394 abandon a DHCP lease of the fixed address to one MAC
1395 address, if another MAC address in the dhcp-host statement
1396 asks for an address. This is useful to give a fixed
1397 address to a host which has two network interfaces
1398 (say, a laptop with wired and wireless interfaces.)
1399 It's very important to ensure that only one interface
1400 at a time is up, since dnsmasq abandons the first lease
1401 and re-uses the address before the leased time has
1402 elapsed. John Gray suggested this.
1403
1404 Tweak the response to a DHCP request packet with a wrong
1405 server-id when --dhcp-authoritative is set; dnsmasq now
1406 returns a DHCPNAK, rather than silently ignoring the
1407 packet. Thanks to Chris Marget for spotting this
1408 improvement.
1409
1410 Add --cname option. This provides a limited alias
1411 function, usable for DHCP names. Thanks to AJ Weber for
1412 suggestions on this.
1413
1414 Updated contrib/webmin with latest version from Neil
1415 Fisher.
1416
1417 Updated Polish translation. Thanks to Jan Psota.
1418
1419 Correct the text names for DHCP options 64 and 65 to be
1420 "nis+-domain" and "nis+-servers".
1421
1422 Updated Spanish translation. Thanks to Chris Chatham.
1423
1424 Force re-reading of /etc/resolv.conf when an "interface
1425 up" event occurs.
1426
1427
1428 version 2.45
1429 Fix total DNS failure in release 2.44 unless --min-port
1430 specified. Thanks to Steven Barth and Grant Coady for
1431 bugreport. Also reject out-of-range port spec, which could
1432 break things too: suggestion from Gilles Espinasse.
1433
1434
1435 version 2.44
1436 Fix crash when unknown client attempts to renew a DHCP
1437 lease, problem introduced in version 2.43. Thanks to
1438 Carlos Carvalho for help chasing this down.
1439
1440 Fix potential crash when a host which doesn't have a lease
1441 does DHCPINFORM. Again introduced in 2.43. This bug has
1442 never been reported in the wild.
1443
1444 Fix crash in netlink code introduced in 2.43. Thanks to
1445 Jean Wolter for finding this.
1446
1447 Change implementation of min_port to work even if min-port
1448 is large.
1449
1450 Patch to enable compilation of latest Mac OS X. Thanks to
1451 David Gilman.
1452
1453 Update Spanish translation. Thanks to Christopher Chatham.
1454
1455
1456 version 2.43
1457 Updated Polish translation. Thanks to Jan Psota.
1458
1459 Flag errors when configuration options are repeated
1460 illegally.
1461
1462 Further tweaks for GNU/kFreeBSD
1463
1464 Add --no-wrap to msgmerge call - provides nicer .po file
1465 format.
1466
1467 Honour lease-time spec in dhcp-host lines even for
1468 BOOTP. The user is assumed to known what they are doing in
1469 this case. (Hosts without the time spec still get infinite
1470 leases for BOOTP, over-riding the default in the
1471 dhcp-range.) Thanks to Peter Katzmann for uncovering this.
1472
1473 Fix problem matching relay-agent ids. Thanks to Michael
1474 Rack for the bug report.
1475
1476 Add --naptr-record option. Suggestion from Johan
1477 Bergquist.
1478
1479 Implement RFC 5107 server-id-override DHCP relay agent
1480 option.
1481
1482 Apply patches from Stefan Kruger for compilation on
1483 Solaris 10 under Sun studio.
1484
1485 Yet more tweaking of Linux capability code, to suppress
1486 pointless wingeing from kernel 2.6.25 and above.
1487
1488 Improve error checking during startup. Previously, some
1489 errors which occurred during startup would be worked
1490 around, with dnsmasq still starting up. Some were logged,
1491 some silent. Now, they all cause a fatal error and dnsmasq
1492 terminates with a non-zero exit code. The errors are those
1493 associated with changing uid and gid, setting process
1494 capabilities and writing the pidfile. Thanks to Uwe
1495 Gansert and the Suse security team for pointing out
1496 this improvement, and Bill Reimers for good implementation
1497 suggestions.
1498
1499 Provide NO_LARGEFILE compile option to switch off largefile
1500 support when compiling against versions of uclibc which
1501 don't support it. Thanks to Stephane Billiart for the patch.
1502
1503 Implement random source ports for interactions with
1504 upstream nameservers. New spoofing attacks have been found
1505 against nameservers which do not do this, though it is not
1506 clear if dnsmasq is vulnerable, since to doesn't implement
1507 recursion. By default dnsmasq will now use a different
1508 source port (and socket) for each query it sends
1509 upstream. This behaviour can suppressed using the
1510 --query-port option, and the old default behaviour
1511 restored using --query-port=0. Explicit source-port
1512 specifications in --server configs are still honoured.
1513
1514 Replace the random number generator, for better
1515 security. On most BSD systems, dnsmasq uses the
1516 arc4random() RNG, which is secure, but on other platforms,
1517 it relied on the C-library RNG, which may be
1518 guessable and therefore allow spoofing. This release
1519 replaces the libc RNG with the SURF RNG, from Daniel
1520 J. Berstein's DJBDNS package.
1521
1522 Don't attempt to change user or group or set capabilities
1523 if dnsmasq is run as a non-root user. Without this, the
1524 change from soft to hard errors when these fail causes
1525 problems for non-root daemons listening on high
1526 ports. Thanks to Patrick McLean for spotting this.
1527
1528 Updated French translation. Thanks to Gildas Le Nadan.
1529
1530
1531 version 2.42
1532 The changelog for version 2.42 and earlier is
1533 available in CHANGELOG.archive.
