Update French translation.
[people/ms/dnsmasq.git] / CHANGELOG
1 version 2.66
2 Add the ability to act as an authoritative DNS
3 server. Dnsmasq can now answer queries from the wider 'net
4 with local data, as long as the correct NS records are set
5 up. Only local data is provided, to avoid creating an open
6 DNS relay. Zone transfer is supported, to allow secondary
7 servers to be configured.
8
9 Add "constructed DHCP ranges" for DHCPv6. This is intended
10 for IPv6 routers which get prefixes dynamically via prefix
11 delegation. With suitable configuration, stateful DHCPv6
12 and RA can happen automatically as prefixes are delegated
13 and then deprecated, without having to re-write the
14 dnsmasq configuration file or restart the daemon. Thanks to
15 Steven Barth for extensive testing and development work on
16 this idea.
17
18 Fix crash on startup on Solaris 11. Regression probably
19 introduced in 2.61. Thanks to Geoff Johnstone for the
20 patch.
21
22 Add code to make behaviour for TCP DNS requests that same
23 as for UDP requests, when a request arrives for an allowed
24 address, but via a banned interface. This change is only
25 active on Linux, since the relevant API is missing (AFAIK)
26 on other platforms. Many thanks to Tomas Hozza for
27 spotting the problem, and doing invaluable discovery of
28 the obscure and undocumented API required for the solution.
29
30 Don't send the default DHCP option advertising dnsmasq as
31 the local DNS server if dnsmasq is configured to not act
32 as DNS server, or it's configured to a non-standard port.
33
34 Add DNSMASQ_CIRCUIT_ID, DNSMASQ_SUBCRIBER_ID,
35 DNSMASQ_REMOTE_ID variables to the environment of the
36 lease-change script (and the corresponding Lua). These hold
37 information inserted into the DHCP request by a DHCP relay
38 agent. Thanks to Lakefield Communications for providing a
39 bounty for this addition.
40
41 Fixed crash, introduced in 2.64, whilst handling DHCPv6
42 information-requests with some common configurations.
43 Thanks to Robert M. Albrecht for the bug report and
44 chasing the problem.
45
46 Add --ipset option. Thanks to Jason A. Donenfeld for the
47 patch.
48
49 Don't erroneously reject some option names in --dhcp-match
50 options. Thanks to Benedikt Hochstrasser for the bug report.
51
52 Allow a trailing '*' wildcard in all interface-name
53 configurations. Thanks to Christian Parpart for the patch.
54
55 Handle the situation where libc headers define
56 SO_REUSEPORT, but the kernel in use doesn't, to cope with
57 the introduction of this option to Linux. Thanks to Rich
58 Felker for the bug report.
59
60 Update Polish translation. Thanks to Jan Psota.
61
62 Fix crash if the configured DHCP lease limit is
63 reached. Regression occurred in 2.61. Thanks to Tsachi for
64 the bug report.
65
66 Update the French translation. Thanks to Gildas le Nadan.
67
68
69 version 2.65
70 Fix regression which broke forwarding of queries sent via
71 TCP which are not for A and AAAA and which were directed to
72 non-default servers. Thanks to Niax for the bug report.
73
74 Fix failure to build with DHCP support excluded. Thanks to
75 Gustavo Zacarias for the patch.
76
77 Fix nasty regression in 2.64 which completely broke cacheing.
78
79
80 version 2.64
81 Handle DHCP FQDN options with all flag bits zero and
82 --dhcp-client-update set. Thanks to Bernd Krumbroeck for
83 spotting the problem.
84
85 Finesse the check for /etc/hosts names which conflict with
86 DHCP names. Previously a name/address pair in /etc/hosts
87 which didn't match the name/address of a DHCP lease would
88 generate a warning. Now that only happesn if there is not
89 also a match. This allows multiple addresses for a name in
90 /etc/hosts with one of them assigned via DHCP.
91
92 Fix broken vendor-option processing for BOOTP. Thanks to
93 Hans-Joachim Baader for the bug report.
94
95 Don't report spurious netlink errors, regression in
96 2.63. Thanks to Vladislav Grishenko for the patch.
97
98 Flag DHCP or DHCPv6 in starup logging. Thanks to
99 Vladislav Grishenko for the patch.
100
101 Add SetServersEx method in DBus interface. Thanks to Dan
102 Williams for the patch.
103
104 Add SetDomainServers method in DBus interface. Thanks to
105 Roy Marples for the patch.
106
107 Fix build with later Lua libraries. Thansk to Cristian
108 Rodriguez for the patch.
109
110 Add --max-cache-ttl option. Thanks to Dennis Kaarsemaker
111 for the patch.
112
113 Fix breakage of --host-record parsing, resulting in
114 infinte loop at startup. Regression in 2.63. Thanks to
115 Haim Gelfenbeyn for spotting this.
116
117 Set SO_REUSEADDRESS and SO_V6ONLY options on the DHCPv6
118 socket, this allows multiple instances of dnsmasq on a
119 single machine, in the same way as for DHCPv4. Thanks to
120 Gene Czarcinski and Vladislav Grishenko for work on this.
121
122 Fix DHCPv6 to do access control correctly when it's
123 configured with --listen-address. Thanks to
124 Gene Czarcinski for sorting this out.
125
126 Add a "wildcard" dhcp-range which works for any IPv6
127 subnet, --dhcp-range=::,static Useful for Stateless
128 DHCPv6. Thanks to Vladislav Grishenko for the patch.
129
130 Don't include lease-time in DHCPACK replies to DHCPINFORM
131 queries, since RFC-2131 says we shouldn't. Thanks to
132 Wouter Ibens for pointing this out.
133
134 Makefile tweak to do dependency checking on header files.
135 Thanks to Johan Peeters for the patch.
136
137 Check interface for outgoing unsolicited router
138 advertisements, rather than relying on interface address
139 configuration. Thanks to Gene Czarinski for the patch.
140
141 Handle better attempts to transmit on interfaces which are
142 still doing DAD, and specifically do not just transmit
143 without setting source address and interface, since this
144 can cause very puzzling effects when a router
145 advertisement goes astray. Thanks again to Gene Czarinski.
146
147 Get RA timers right when there is more than one
148 dhcp-range on a subnet.
149
150
151 version 2.63
152 Do duplicate dhcp-host address check in --test mode.
153
154 Check that tftp-root directories are accessible before
155 start-up. Thanks to Daniel Veillard for the initial patch.
156
157 Allow more than one --tfp-root flag. The per-interface
158 stuff is pointless without that.
159
160 Add --bind-dynamic. A hybrid mode between the default and
161 --bind-interfaces which copes with dynamically created
162 interfaces.
163
164 A couple of fixes to the build system for Android. Thanks
165 to Metin Kaya for the patches.
166
167 Remove the interface:<interface> argument in --dhcp-range, and
168 the interface argument to --enable-tftp. These were a
169 still-born attempt to allow automatic isolated
170 configuration by libvirt, but have never (to my knowledge)
171 been used, had very strange semantics, and have been
172 superceded by other mechanisms.
173
174 Fixed bug logging filenames when duplicate dhcp-host
175 addresses are found. Thanks to John Hanks for the patch.
176
177 Fix regression in 2.61 which broke caching of CNAME
178 chains. Thanks to Atul Gupta for the bug report.
179
180 Allow the target of a --cname flag to be another --cname.
181
182 Teach DHCPv6 about the RFC 4242 information-refresh-time
183 option, and add parsing if the minutes, hours and days
184 format for options. Thanks to Francois-Xavier Le Bail for
185 the suggestion.
186
187 Allow "w" (for week) as multiplier in lease times, as well
188 as seconds, minutes, hours and days. Álvaro Gámez Machado
189 spotted the ommission.
190
191 Update French translation. Thanks to Gildas Le Nadan.
192
193 Allow a DBus service name to be given with --enable-dbus
194 which overrides the default,
195 uk.org.thekelleys.dnsmasq. Thanks to Mathieu
196 Trudel-Lapierre for the patch.
197
198 Set the "prefix on-link" bit in Router
199 Advertisements. Thanks to Gui Iribarren for the patch.
200
201
202 version 2.62
203 Update German translation. Thanks to Conrad Kostecki.
204
205 Cope with router-solict packets wich don't have a valid
206 source address. Thanks to Vladislav Grishenko for the patch.
207
208 Fixed bug which caused missing periodic router
209 advertisements with some configurations. Thanks to
210 Vladislav Grishenko for the patch.
211
212 Fixed bug which broke DHCPv6/RA with prefix lengths
213 which are not divisible by 8. Thanks to Andre Coetzee
214 for spotting this.
215
216 Fix non-response to router-solicitations when
217 router-advertisement configured, but DHCPv6 not
218 configured. Thanks to Marien Zwart for the patch.
219
220 Add --dns-rr, to allow arbitrary DNS resource records.
221
222 Fixed bug which broke RA scheduling when an interface had
223 two addresses in the same network. Thanks to Jim Bos for
224 his help nailing this.
225
226 version 2.61
227 Re-write interface discovery code on *BSD to use
228 getifaddrs. This is more portable, more straightforward,
229 and allows us to find the prefix length for IPv6
230 addresses.
231
232 Add ra-names, ra-stateless and slaac keywords for DHCPv6.
233 Dnsmasq can now synthesise AAAA records for dual-stack
234 hosts which get IPv6 addresses via SLAAC. It is also now
235 possible to use SLAAC and stateless DHCPv6, and to
236 tell clients to use SLAAC addresses as well as DHCP ones.
237 Thanks to Dave Taht for help with this.
238
239 Add --dhcp-duid to allow DUID-EN uids to be used.
240
241 Explicity send DHCPv6 replies to the correct port, instead
242 of relying on clients to send requests with the correct
243 source address, since at least one client in the wild gets
244 this wrong. Thanks to Conrad Kostecki for help tracking
245 this down.
246
247 Send a preference value of 255 in DHCPv6 replies when
248 --dhcp-authoritative is in effect. This tells clients not
249 to wait around for other DHCP servers.
250
251 Better logging of DHCPv6 options.
252
253 Add --host-record. Thanks to Rob Zwissler for the
254 suggestion.
255
256 Invoke the DHCP script with action "tftp" when a TFTP file
257 transfer completes. The size of the file, address to which
258 it was sent and complete pathname are supplied. Note that
259 version 2.60 introduced some script incompatibilties
260 associated with DHCPv6, and this is a further change. To
261 be safe, scripts should ignore unknown actions, and if
262 not IPv6-aware, should exit if the environment
263 variable DNSMASQ_IAID is set. The use-case for this is
264 to track netboot/install. Suggestion from Shantanu
265 Gadgil.
266
267 Update contrib/port-forward/dnsmasq-portforward to reflect
268 the above.
269
270 Set the environment variable DNSMASQ_LOG_DHCP when running
271 the script id --log-dhcp is in effect, so that script can
272 taylor their logging verbosity. Suggestion from Malte
273 Forkel.
274
275 Arrange that addresses specified with --listen-address
276 work even if there is no interface carrying the
277 address. This is chiefly useful for IPv4 loopback
278 addresses, where any address in 127.0.0.0/8 is a valid
279 loopback address, but normally only 127.0.0.1 appears on
280 the lo interface. Thanks to Mathieu Trudel-Lapierre for
281 the idea and initial patch.
282
283 Fix crash, introduced in 2.60, when a DHCPINFORM is
284 received from a network which has no valid dhcp-range.
285 Thanks to Stephane Glondu for the bug report.
286
287 Add a new DHCP lease time keyword, "deprecated" for
288 --dhcp-range. This is only valid for IPv6, and sets the
289 preffered lease time for both DHCP and RA to zero. The
290 effect is that clients can continue to use the address
291 for existing connections, but new connections will use
292 other addresses, if they exist. This makes hitless
293 renumbering at least possible.
294
295 Fix bug in address6_available() which caused DHCPv6 lease
296 aquisition to fail if more than one dhcp-range in use.
297
298 Provide RDNSS and DNSSL data in router advertisements,
299 using the settings provided for DHCP options
300 option6:domain-search and option6:dns-server.
301
302 Tweak logo/favicon.ico to add some transparency. Thanks to
303 SamLT for work on this.
304
305 Don't cache data from non-recursive nameservers, since it
306 may erroneously look like a valid CNAME to a non-exitant
307 name. Thanks to Ben Winslow for finding this.
308
309 Call SO_BINDTODEVICE on the DHCP socket(s) when doing DHCP
310 on exactly one interface and --bind-interfaces is set. This
311 makes the OpenStack use-case of one dnsmasq per virtual
312 interface work. This is only available on Linux; it's not
313 supported on other platforms. Thanks to Vishvananda Ishaya
314 and the OpenStack team for the suggestion.
315
316 Updated French translation. Thanks to Gildas Le Nadan.
317
318 Give correct from-cache answers to explict CNAME queries.
319 Thanks to Rob Zwissler for spotting this.
320
321 Add --tftp-lowercase option. Thanks to Oliver Rath for the
322 patch.
323
324 Ensure that the DBus DhcpLeaseUpdated events are generated
325 when a lease goes through INIT_REBOOT state, even if the
326 dhcp-script is not in use. Thanks to Antoaneta-Ecaterina
327 Ene for the patch.
328
329 Fix failure of TFTP over IPv4 on OpenBSD platform. Thanks
330 to Brad Smith for spotting this.
331
332
333 version 2.60
334 Fix compilation problem in Mac OS X Lion. Thanks to Olaf
335 Flebbe for the patch.
336
337 Fix DHCP when using --listen-address with an IP address
338 which is not the primary address of an interface.
339
340 Add --dhcp-client-update option.
341
342 Add Lua integration. Dnsmasq can now execute a DHCP
343 lease-change script written in Lua. This needs to be
344 enabled at compile time by setting HAVE_LUASCRIPT in
345 src/config.h or running "make COPTS=-DHAVE_LUASCRIPT"
346 Thanks to Jan-Piet Mens for the idea and proof-of-concept
347 implementation.
348
349 Tidied src/config.h to distinguish between
350 platform-dependent compile-time options which are selected
351 automatically, and builder-selectable compile time
352 options. Document the latter better, and describe how to
353 set them from the make command line.
354
355 Tidied up IPPROTO_IP/SOL_IP (and IPv6 equivalent)
356 confusion. IPPROTO_IP works everywhere now.
357
358 Set TOS on DHCP sockets, this improves things on busy
359 wireless networks. Thanks to Dave Taht for the patch.
360
361 Determine VERSION automatically based on git magic:
362 release tags or hash values.
363
364 Improve start-up speed when reading large hosts files
365 containing many distinct addresses.
366
367 Fix problem if dnsmasq is started without the stdin,
368 stdout and stderr file descriptors open. This can manifest
369 itself as 100% CPU use. Thanks to Chris Moore for finding
370 this.
371
372 Fix shell-scripting bug in bld/pkg-wrapper. Thanks to
373 Mark Mitchell for the patch.
374
375 Allow the TFP server or boot server in --pxe-service, to
376 be a domain name instead of an IP address. This allows for
377 round-robin to multiple servers, in the same way as
378 --dhcp-boot. A good suggestion from Cristiano Cumer.
379
380 Support BUILDDIR variable in the Makefile. Allows builds
381 for multiple archs from the same source tree with eg.
382 make BUILDDIR=linux (relative to dnsmasq tree)
383 make BUILDDIR=/tmp/openbsd (absolute path)
384 If BUILDDIR is not set, compilation happens in the src
385 directory, as before. Suggestion from Mark Mitchell.
386
387 Support DHCPv6. Support is there for the sort of things
388 the existing v4 server does, including tags, options,
389 static addresses and relay support. Missing is prefix
390 delegation, which is probably not required in the dnsmasq
391 niche, and an easy way to accept prefix delegations from
392 an upstream DHCPv6 server, which is. Future plans include
393 support for DHCPv6 router option and MAC address option
394 (to make selecting clients by MAC address work like IPv4).
395 These will be added as the standards mature.
396 This code has been tested, but this is the first release,
397 so don't bet the farm on it just yet. Many thanks to all
398 testers who have got it this far.
399
400 Support IPv6 router advertisements. This is a
401 simple-minded implementation, aimed at providing the
402 vestigial RA needed to go alongside IPv6. Is picks up
403 configuration from the DHCPv6 conf, and should just need
404 enabling with --enable-ra.
405
406 Fix long-standing wrinkle with --localise-queries that
407 could result in wrong answers when DNS packets arrive
408 via an interface other than the expected one. Thanks to
409 Lorenzo Milesi and John Hanks for spotting this one.
410
411 Update French translation. Thanks to Gildas Le Nadan.
412
413 Update Polish translation. Thanks to Jan Psota.
414
415
416 version 2.59
417 Fix regression in 2.58 which caused failure to start up
418 with some combinations of dnsmasq config and IPv6 kernel
419 network config. Thanks to Brielle Bruns for the bug
420 report.
421
422 Improve dnsmasq's behaviour when network interfaces are
423 still doing duplicate address detection (DAD). Previously,
424 dnsmasq would wait up to 20 seconds at start-up for the
425 DAD state to terminate. This is broken for bridge
426 interfaces on recent Linux kernels, which don't start DAD
427 until the bridge comes up, and so can take arbitrary
428 time. The new behaviour lets dnsmasq poll for an arbitrary
429 time whilst providing service on other interfaces. Thanks
430 to Stephen Hemminger for pointing out the problem.
431
432
433 version 2.58
434 Provide a definition of the SA_SIZE macro where it's
435 missing. Fixes build failure on openBSD.
436
437 Don't include a zero terminator at the end of messages
438 sent to /dev/log when /dev/log is a datagram socket.
439 Thanks to Didier Rabound for spotting the problem.
440
441 Add --dhcp-sequential-ip flag, to force allocation of IP
442 addresses in ascending order. Note that the default
443 pseudo-random mode is in general better but some
444 server-deployment applications need this.
445
446 Fix problem where a server-id of 0.0.0.0 is sent to a
447 client when a dhcp-relay is in use if a client renews a
448 lease after dnsmasq restart and before any clients on the
449 subnet get a new lease. Thanks to Mike Ruiz for assistance
450 in chasing this one down.
451
452 Don't return NXDOMAIN to an AAAA query if we have CNAME
453 which points to an A record only: NODATA is the correct
454 reply in this case. Thanks to Tom Fernandes for spotting
455 the problem.
456
457 Relax the need to supply a netmask in --dhcp-range for
458 networks which use a DHCP relay. Whilst this is still
459 desireable, in the absence of a netmask dnsmasq will use
460 a default based on the class (A, B, or C) of the address.
461 This should at least remove a cause of mysterious failure
462 for people using RFC1918 addresses and relays.
463
464 Add support for Linux conntrack connection marking. If
465 enabled with --conntrack, the connection mark for incoming
466 DNS queries will be copied to the outgoing connections
467 used to answer those queries. This allows clever firewall
468 and accounting stuff. Only available if dnsmasq is
469 compiled with HAVE_CONNTRACK and adds a dependency on
470 libnetfilter-conntrack. Thanks to Ed Wildgoose for the
471 initial idea, testing and sponsorship of this function.
472
473 Provide a sane error message when someone attempts to
474 match a tag in --dhcp-host.
475
476 Tweak the behaviour of --domain-needed, to avoid problems
477 with recursive nameservers downstream of dnsmasq. The new
478 behaviour only stops A and AAAA queries, and returns
479 NODATA rather than NXDOMAIN replies.
480
481 Efficiency fix for very large DHCP configurations, thanks
482 to James Gartrell and Mike Ruiz for help with this.
483
484 Allow the TFTP-server address in --dhcp-boot to be a
485 domain-name which is looked up in /etc/hosts. This can
486 give multiple IP addresses which are used round-robin,
487 thus doing TFTP server load-balancing. Thanks to Sushil
488 Agrawal for the patch.
489
490 When two tagged dhcp-options for a particular option
491 number are both valid, use the one which is valid without
492 a tag from the dhcp-range. Allows overriding of the value
493 of a DHCP option for a particular host as well as
494 per-network values. So
495 --dhcp-range=set:interface1,......
496 --dhcp-host=set:myhost,.....
497 --dhcp-option=tag:interface1,option:nis-domain,"domain1"
498 --dhcp-option=tag:myhost,option:nis-domain,"domain2"
499 will set the NIS-domain to domain1 for hosts in the range, but
500 override that to domain2 for a particular host.
501
502 Fix bug which resulted in truncated files and timeouts for
503 some TFTP transfers. The bug only occurs with netascii
504 transfers and needs an unfortunate relationship between
505 file size, blocksize and the number of newlines in the
506 last block before it manifests itself. Many thanks to
507 Alkis Georgopoulos for spotting the problem and providing
508 a comprehensive test-case.
509
510 Fix regression in TFTP server on *BSD platforms introduced
511 in version 2.56, due to confusion with sockaddr
512 length. Many thanks to Loic Pefferkorn for finding this.
513
514 Support scope-ids in IPv6 addresses of nameservers from
515 /etc/resolv.conf and in --server options. Eg
516 nameserver fe80::202:a412:4512:7bbf%eth0 or
517 server=fe80::202:a412:4512:7bbf%eth0. Thanks to
518 Michael Stapelberg for the suggestion.
519
520 Update Polish translation, thanks to Jan Psota.
521
522 Update French translation. Thanks to Gildas Le Nadan.
523
524
525 version 2.57
526 Add patches to allow build under Android.
527
528 Provide our own header for the DNS protocol, rather than
529 relying on arpa/nameser.h. This has proved more or less
530 defective over the years and the final straw is that it's
531 effectively empty on Android.
532
533 Fix regression in 2.56 which caused hex constants in
534 configuration to be rejected if they contain the '*'
535 wildcard.
536
537 Correct wrong casts of arguments to ctype.h functions,
538 isdigit(), isxdigit() etc. Thanks to Matthias Andree for
539 spotting this.
540
541 Allow build with IDN support independently from i18n.
542 IDN support continues to be included automatically
543 when i18n is included.
544 'make COPTS=-DHAVE_IDN' is the magic incantation.
545
546 Modify check on extraneous command line junk (added in
547 2.56) so that it doesn't complain about extra _empty_
548 arguments. Otherwise this breaks libvirt.
549
550
551 version 2.56
552 Add a patch to allow dnsmasq to get interface names right in a
553 Solaris zone. Thanks to Dj Padzensky for this.
554
555 Improve data-type parsing heuristics so that
556 --dhcp-option=option:domain-search,.
557 treats the value as a string and not an IP address.
558 Thanks to Clemens Fischer for spotting that.
559
560 Add IPv6 support to the TFTP server. Many thanks to Jan
561 'RedBully' Seiffert for the patches.
562
563 Log DNS queries at level LOG_INFO, rather then
564 LOG_DEBUG. This makes things consistent with DHCP
565 logging. Thanks to Adam Pribyl for spotting the problem.
566
567 Ensure that dnsmasq terminates cleanly when using
568 --syslog-async even if it cannot make a connection to the
569 syslogd.
570
571 Add --add-mac option. This is to support currently
572 experimental DNS filtering facilities. Thanks to Benjamin
573 Petrin for the orignal patch.
574
575 Fix bug which meant that tags were ignored in dhcp-range
576 configuration specifying PXE-proxy service. Thanks to
577 Cristiano Cumer for spotting this.
578
579 Raise an error if there is extra junk, not part of an
580 option, on the command line.
581
582 Flag a couple of log messages in cache.c as coming from
583 the DHCP subsystem. Thanks to Olaf Westrik for the patch.
584
585 Omit timestamps from logs when a) logging to stderr and
586 b) --keep-in-forground is set. The logging facility on the
587 other end of stderr can be assumned to supply them. Thanks
588 to John Hallam for the patch.
589
590 Don't complain about strings longer than 255 characters in
591 --txt-record, just split the long strings into 255
592 character chunks instead.
593
594 Fix crash on double-free. This bug can only happen when
595 dhcp-script is in use and then only in rare circumstances
596 triggered by high DHCP transaction rate and a slow
597 script. Thanks to Ferenc Wagner for finding the problem.
598
599 Only log that a file has been sent by TFTP after the
600 transfer has completed succesfully.
601
602 A good suggestion from Ferenc Wagner: extend
603 the --domain option to allow this sort of thing:
604 --domain=thekelleys.org.uk,192.168.0.0/24,local
605 which automatically creates
606 --local=/thekelleys.org.uk/
607 --local=/0.168.192.in-addr.arpa/
608
609 Tighten up syntax checking of hex contants in the config
610 file. Thanks to Fred Damen for spotting this.
611
612 Add dnsmasq logo/icon, contributed by Justin Swift. Many
613 thanks for that.
614
615 Never cache DNS replies which have the 'cd' bit set, or
616 which result from queries forwarded with the 'cd' bit
617 set. The 'cd' bit instructs a DNSSEC validating server
618 upstream to ignore signature failures and return replies
619 anyway. Without this change it's possible to pollute the
620 dnsmasq cache with bad data by making a query with the
621 'cd' bit set and subsequent queries would return this data
622 without its being marked as suspect. Thanks to Anders
623 Kaseorg for pointing out this problem.
624
625 Add --proxy-dnssec flag, for compliance with RFC
626 4035. Dnsmasq will now clear the 'ad' bit in answers returned
627 from upstream validating nameservers unless this option is
628 set.
629
630 Allow a filename of "-" for --conf-file to read
631 stdin. Suggestion from Timothy Redaelli.
632
633 Rotate the order of SRV records in replies, to provide
634 round-robin load balancing when all the priorities are
635 equal. Thanks to Peter McKinney for the suggestion.
636
637 Edit
638 contrib/MacOSX-launchd/uk.org.thekelleys.dnsmasq.plist
639 so that it doesn't log all queries to a file by
640 default. Thanks again to Peter McKinney.
641
642 By default, setting an IPv4 address for a domain but not
643 an IPv6 address causes dnsmasq to return
644 an NODATA reply for IPv6 (or vice-versa). So
645 --address=/google.com/1.2.3.4 stops IPv6 queries for
646 *google.com from being forwarded. Make it possible to
647 override this behaviour by defining the sematics if the
648 same domain appears in both --server and --address.
649 In that case, the --address has priority for the address
650 family in which is appears, but the --server has priority
651 of the address family which doesn't appear in --adddress
652 So:
653 --address=/google.com/1.2.3.4
654 --server=/google.com/#
655 will return 1.2.3.4 for IPv4 queries for *.google.com but
656 forward IPv6 queries to the normal upstream nameserver.
657 Similarly when setting an IPv6 address
658 only this will allow forwarding of IPv4 queries. Thanks to
659 William for pointing out the need for this.
660
661 Allow more than one --dhcp-optsfile and --dhcp-hostsfile
662 and make them understand directories as arguments in the
663 same way as --addn-hosts. Suggestion from John Hanks.
664
665 Ignore rebinding requests for leases we don't know
666 about. Rebind is broadcast, so we might get to overhear a
667 request meant for another DHCP server. NAKing this is
668 wrong. Thanks to Brad D'Hondt for assistance with this.
669
670 Fix cosmetic bug which produced strange output when
671 dumping cache statistics with some configurations. Thanks
672 to Fedor Kozhevnikov for spotting this.
673
674
675 version 2.55
676 Fix crash when /etc/ethers is in use. Thanks to
677 Gianluigi Tiesi for finding this.
678
679 Fix crash in netlink_multicast(). Thanks to Arno Wald for
680 finding this one.
681
682 Allow the empty domain "." in dhcp domain-search (119)
683 options.
684
685
686 version 2.54
687 There is no version 2.54 to avoid confusion with 2.53,
688 which incorrectly identifies itself as 2.54.
689
690
691 version 2.53
692 Fix failure to compile on Debian/kFreeBSD. Thanks to
693 Axel Beckert and Petr Salinger.
694
695 Fix code to avoid scary strict-aliasing warnings
696 generated by gcc 4.4.
697
698 Added FAQ entry warning about DHCP failures with Vista
699 when firewalls block 255.255.255.255.
700
701 Fixed bug which caused bad things to happen if a
702 resolv.conf file which exists is subsequently removed.
703 Thanks to Nikolai Saoukh for the patch.
704
705 Rationalised the DHCP tag system. Every configuration item
706 which can set a tag does so by adding "set:<tag>" and
707 every configuration item which is conditional on a tag is
708 made so by "tag:<tag>". The NOT operator changes to '!',
709 which is a bit more intuitive too. Dhcp-host directives
710 can set more than one tag now. The old '#' NOT,
711 "net:" prefix and no-prefixes are still honoured, so
712 no existing config file needs to be changed, but
713 the documentation and new-style config files should be
714 much less confusing.
715
716 Added --tag-if to allow boolean operations on tags.
717 This allows complicated logic to be clearer and more
718 general. A great suggestion from Richard Voigt.
719
720 Add broadcast/unicast information to DHCP logging.
721
722 Allow --dhcp-broadcast to be unconditional.
723
724 Fixed incorrect behaviour with NOT <tag> conditionals in
725 dhcp-options. Thanks to Max Turkewitz for assistance
726 finding this.
727
728 If we send vendor-class encapsulated options based on the
729 vendor-class supplied by the client, and no explicit
730 vendor-class option is given, echo back the vendor-class
731 from the client.
732
733 Fix bug which stopped dnsmasq from matching both a
734 circuitid and a remoteid. Thanks to Ignacio Bravo for
735 finding this.
736
737 Add --dhcp-proxy, which makes it possible to configure
738 dnsmasq to use a DHCP relay agent as a full proxy, with
739 all DHCP messages passing through the proxy. This is
740 useful if the relay adds extra information to the packets
741 it forwards, but cannot be configured with the RFC 5107
742 server-override option.
743
744 Added interface:<iface name> part to dhcp-range. The
745 semantics of this are very odd at first sight, but it
746 allows a single line of the form
747 dhcp-range=interface:virt0,192.168.0.4,192.168.0.200
748 to be added to dnsmasq configuration which then supplies
749 DHCP and DNS services to that interface, without affecting
750 what services are supplied to other interfaces and
751 irrespective of the existance or lack of
752 interface=<interface>
753 lines elsewhere in the dnsmasq configuration. The idea is
754 that such a line can be added automatically by libvirt
755 or equivalent systems, without disturbing any manual
756 configuration.
757
758 Similarly to the above, allow --enable-tftp=<interface>
759
760 Allow a TFTP root to be set separately for requests via
761 different interfaces, --tftp-root=<path>,<interface>
762
763 Correctly handle and log clashes between CNAMES and
764 DNS names being given to DHCP leases. This fixes a bug
765 which caused nonsense IP addresses to be logged. Thanks to
766 Sergei Zhirikov for finding and analysing the problem.
767
768 Tweak flush_log so as to avoid leaving the log
769 file in non-blocking mode. O_NONBLOCK is a property of the
770 file, not the process/descriptor.
771
772 Fix contrib/Solaris10/create_package
773 (/usr/man -> /usr/share/man) Thanks to Vita Batrla.
774
775 Fix a problem where, if a client got a lease, then went
776 to another subnet and got another lease, then moved back,
777 it couldn't resume the old lease, but would instead get
778 a new address. Thanks to Leonardo Rodrigues for spotting
779 this and testing the fix.
780
781 Fix weird bug which sometimes omitted certain characters
782 from the start of quoted strings in dhcp-options. Thanks
783 to Dayton Turner for spotting the problem.
784
785 Add facility to redirect some domains to the standard
786 upstream servers: this allows something like
787 --server=/google.com/1.2.3.4 --server=/www.google.com/#
788 which will send queries for *.google.com to 1.2.3.4,
789 except *www.google.com which will be forwarded as usual.
790 Thanks to AJ Weber for prompting this addition.
791
792 Improve the hash-algorithm used to generate IP addresses
793 from MAC addresses during initial DHCP address
794 allocation. This improves performance when large numbers
795 of hosts with similar MAC addresses all try and get an IP
796 address at the same time. Thanks to Paul Smith for his
797 work on this.
798
799 Tweak DHCP code so that --bridge-interface can be used to
800 select which IP alias of an interface should be used for
801 DHCP purposes on Linux. If eth0 has an alias eth0:dhcp
802 then adding --bridge-interface=eth0:dhcp,eth0 will use
803 the address of eth0:dhcp to determine the correct subnet
804 for DHCP address allocation. Thanks to Pawel Golaszewski
805 for prompting this and Eric Cooper for further testing.
806
807 Add --dhcp-generate-names. Suggestion by Ferenc Wagner.
808
809 Tweak DNS server selection algorithm when there is more
810 than one server available for a domain, eg.
811 --server=/mydomain/1.1.1.1
812 --server=/mydomain/2.2.2.2
813 Thanks to Alberto Cuesta-Canada for spotting a weakness
814 here.
815
816 Add --max-ttl. Thanks to Fredrik Ringertz for the patch.
817
818 Allow --log-facility=- to force all logging to
819 stderr. Suggestion from Clemens Fischer.
820
821 Fix regression which caused configuration like
822 --address=/.domain.com/1.2.3.4 to be rejected. The dot to the
823 left of the domain has been implied and not required for a
824 long time, but it should be accepted for backward
825 compatibility. Thanks to Andrew Burcin for spotting this.
826
827 Add --rebind-domain-ok and --rebind-localhost-ok.
828 Suggestion from Clemens Fischer.
829
830 Log replies to queries of type TXT, when --log-queries
831 is set.
832
833 Fix compiler warnings when compiled with -DNO_DHCP. Thanks
834 to Shantanu Gadgil for the patch.
835
836 Updated French translation. Thanks to Gildas Le Nadan.
837
838 Updated Polish translation. Thanks to Jan Psota.
839
840 Updated German translation. Thanks to Matthias Andree.
841
842 Added contrib/static-arp, thanks to Darren Hoo.
843
844 Fix corruption of the domain when a name from /etc/hosts
845 overrides one supplied by a DHCP client. Thanks to Fedor
846 Kozhevnikov for spotting the problem.
847
848 Updated Spanish translation. Thanks to Chris Chatham.
849
850
851 version 2.52
852 Work around a Linux kernel bug which insists that the
853 length of the option passed to setsockopt must be at least
854 sizeof(int) bytes, even if we're calling SO_BINDTODEVICE
855 and the device name is "lo". Note that this is fixed
856 in kernel 2.6.31, but the workaround is harmless and
857 allows earlier kernels to be used. Also fix dnsmasq
858 bug which reported the wrong address when this failed.
859 Thanks to Fedor for finding this.
860
861 The API for IPv6 PKTINFO changed around Linux kernel
862 2.6.14. Workaround the case where dnsmasq is compiled
863 against newer headers, but then run on an old kernel:
864 necessary for some *WRT distros.
865
866 Re-read the set of network interfaces when re-loading
867 /etc/resolv.conf if --bind-interfaces is not set. This
868 handles the case that loopback interfaces do not exist
869 when dnsmasq is first started.
870
871 Tweak the PXE code to support port 4011. This should
872 reduce broadcasts and make things more reliable when other
873 servers are around. It also improves inter-operability
874 with certain clients.
875
876 Make a pxe-service configuration with no filename or boot
877 service type legal: this does a local boot. eg.
878 pxe-service=x86PC, "Local boot"
879
880 Be more conservative in detecting "A for A"
881 queries. Dnsmasq checks if the name in a type=A query looks
882 like a dotted-quad IP address and answers the query itself
883 if so, rather than forwarding it. Previously dnsmasq
884 relied in the library function inet_addr() to convert
885 addresses, and that will accept some things which are
886 confusing in this context, like 1.2.3 or even just
887 1234. Now we only do A for A processing for four decimal
888 numbers delimited by dots.
889
890 A couple of tweaks to fix compilation on Solaris. Thanks
891 to Joel Macklow for help with this.
892
893 Another Solaris compilation tweak, needed for Solaris
894 2009.06. Thanks to Lee Essen for that.
895
896 Added extract packaging stuff from Lee Essen to
897 contrib/Solaris10.
898
899 Increased the default limit on number of leases to 1000
900 (from 150). This is mainly a defence against DoS attacks,
901 and for the average "one for two class C networks"
902 installation, IP address exhaustion does that just as
903 well. Making the limit greater than the number of IP
904 addresses available in such an installation removes a
905 surprise which otherwise can catch people out.
906
907 Removed extraneous trailing space in the value of the
908 DNSMASQ_TIME_REMAINING DNSMASQ_LEASE_LENGTH and
909 DNSMASQ_LEASE_EXPIRES environment variables. Thanks to
910 Gildas Le Nadan for spotting this.
911
912 Provide the network-id tags for a DHCP transaction to
913 the lease-change script in the environment variable
914 DNSMASQ_TAGS. A good suggestion from Gildas Le Nadan.
915
916 Add support for RFC3925 "Vendor-Identifying Vendor
917 Options". The syntax looks like this:
918 --dhcp-option=vi-encap:<enterprise number>, .........
919
920 Add support to --dhcp-match to allow matching against
921 RFC3925 "Vendor-Identifying Vendor Classes". The syntax
922 looks like this:
923 --dhcp-match=tag,vi-encap<enterprise number>, <value>
924
925 Add some application specific code to assist in
926 implementing the Broadband forum TR069 CPE-WAN
927 specification. The details are in contrib/CPE-WAN/README
928
929 Increase the default DNS packet size limit to 4096, as
930 recommended by RFC5625 section 4.4.3. This can be
931 reconfigured using --edns-packet-max if needed. Thanks to
932 Francis Dupont for pointing this out.
933
934 Rewrite query-ids even for TSIG signed packets, since
935 this is allowed by RFC5625 section 4.5.
936
937 Use getopt_long by default on OS X. It has been supported
938 since version 10.3.0. Thanks to Arek Dreyer for spotting
939 this.
940
941 Added up-to-date startup configuration for MacOSX/launchd
942 in contrib/MacOSX-launchd. Thanks to Arek Dreyer for
943 providing this.
944
945 Fix link error when including Dbus but excluding DHCP.
946 Thanks to Oschtan for the bug report.
947
948 Updated French translation. Thanks to Gildas Le Nadan.
949
950 Updated Polish translation. Thanks to Jan Psota.
951
952 Updated Spanish translation. Thanks to Chris Chatham.
953
954 Fixed confusion about domains, when looking up DHCP hosts
955 in /etc/hosts. This could cause spurious "Ignoring
956 domain..." messages. Thanks to Fedor Kozhevnikov for
957 finding and analysing the problem.
958
959
960 version 2.51
961 Add support for internationalised DNS. Non-ASCII characters
962 in domain names found in /etc/hosts, /etc/ethers and
963 /etc/dnsmasq.conf will be correctly handled by translation to
964 punycode, as specified in RFC3490. This function is only
965 available if dnsmasq is compiled with internationalisation
966 support, and adds a dependency on GNU libidn. Without i18n
967 support, dnsmasq continues to be compilable with just
968 standard tools. Thanks to Yves Dorfsman for the
969 suggestion.
970
971 Add two more environment variables for lease-change scripts:
972 First, DNSMASQ_SUPPLIED_HOSTNAME; this is set to the hostname
973 supplied by a client, even if the actual hostname used is
974 over-ridden by dhcp-host or dhcp-ignore-names directives.
975 Also DNSMASQ_RELAY_ADDRESS which gives the address of
976 a DHCP relay, if used.
977 Suggestions from Michael Rack.
978
979 Fix regression which broke echo of relay-agent
980 options. Thanks to Michael Rack for spotting this.
981
982 Don't treat option 67 as being interchangeable with
983 dhcp-boot parameters if it's specified as
984 dhcp-option-force.
985
986 Make the code to call scripts on lease-change compile-time
987 optional. It can be switched off by editing src/config.h
988 or building with "make COPTS=-DNO_SCRIPT".
989
990 Make the TFTP server cope with filenames from Windows/DOS
991 which use '\' as pathname separator. Thanks to Ralf for
992 the patch.
993
994 Updated Polish translation. Thanks to Jan Psota.
995
996 Warn if an IP address is duplicated in /etc/ethers. Thanks
997 to Felix Schwarz for pointing this out.
998
999 Teach --conf-dir to take an option list of file suffices
1000 which will be ignored when scanning the directory. Useful
1001 for backup files etc. Thanks to Helmut Hullen for the
1002 suggestion.
1003
1004 Add new DHCP option named tftpserver-address, which
1005 corresponds to the third argument of dhcp-boot. This
1006 allows the complete functionality of dhcp-boot to be
1007 replicated with dhcp-option. Useful when using
1008 dhcp-optsfile.
1009
1010 Test which upstream nameserver to use every 10 seconds
1011 or 50 queries and not just when a query times out and
1012 is retried. This should improve performance when there
1013 is a slow nameserver in the list. Thanks to Joe for the
1014 suggestion.
1015
1016 Don't do any PXE processing, even for clients with the
1017 correct vendorclass, unless at least one pxe-prompt or
1018 pxe-service option is given. This stops dnsmasq
1019 interfering with proxy PXE subsystems when it is just
1020 the DHCP server. Thanks to Spencer Clark for spotting this.
1021
1022 Limit the blocksize used for TFTP transfers to a value
1023 which avoids packet fragmentation, based on the MTU of the
1024 local interface. Many netboot ROMs can't cope with
1025 fragmented packets.
1026
1027 Honour dhcp-ignore configuration for PXE and proxy-PXE
1028 requests. Thanks to Niels Basjes for the bug report.
1029
1030 Updated French translation. Thanks to Gildas Le Nadan.
1031
1032
1033 version 2.50
1034 Fix security problem which allowed any host permitted to
1035 do TFTP to possibly compromise dnsmasq by remote buffer
1036 overflow when TFTP enabled. Thanks to Core Security
1037 Technologies and Iván Arce, Pablo Hernán Jorge, Alejandro
1038 Pablo Rodriguez, Martín Coco, Alberto Soliño Testa and
1039 Pablo Annetta. This problem has Bugtraq id: 36121
1040 and CVE: 2009-2957
1041
1042 Fix a problem which allowed a malicious TFTP client to
1043 crash dnsmasq. Thanks to Steve Grubb at Red Hat for
1044 spotting this. This problem has Bugtraq id: 36120 and
1045 CVE: 2009-2958
1046
1047
1048 version 2.49
1049 Fix regression in 2.48 which disables the lease-change
1050 script. Thanks to Jose Luis Duran for spotting this.
1051
1052 Log TFTP "file not found" errors. These were not logged,
1053 since a normal PXELinux boot generates many of them, but
1054 the lack of the messages seems to be more confusing than
1055 routinely seeing them when there is no real error.
1056
1057 Update Spanish translation. Thanks to Chris Chatham.
1058
1059
1060 version 2.48
1061 Archived the extensive, backwards, changelog to
1062 CHANGELOG.archive. The current changelog now runs from
1063 version 2.43 and runs conventionally.
1064
1065 Fixed bug which broke binding of servers to physical
1066 interfaces when interface names were longer than four
1067 characters. Thanks to MURASE Katsunori for the patch.
1068
1069 Fixed netlink code to check that messages come from the
1070 correct source, and not another userspace process. Thanks
1071 to Steve Grubb for the patch.
1072
1073 Maintainability drive: removed bug and missing feature
1074 workarounds for some old platforms. Solaris 9, OpenBSD
1075 older than 4.1, Glibc older than 2.2, Linux 2.2.x and
1076 DBus older than 1.1.x are no longer supported.
1077
1078 Don't read included configuration files more than once:
1079 allows complex configuration structures without problems.
1080
1081 Mark log messages from the various subsystems in dnsmasq:
1082 messages from the DHCP subsystem now have the ident string
1083 "dnsmasq-dhcp" and messages from TFTP have ident
1084 "dnsmasq-tftp". Thanks to Olaf Westrik for the patch.
1085
1086 Fix possible infinite DHCP protocol loop when an IP
1087 address nailed to a hostname (not a MAC address) and a
1088 host sometimes provides the name, sometimes not.
1089
1090 Allow --addn-hosts to take a directory: all the files
1091 in the directory are read. Thanks to Phil Cornelius for
1092 the suggestion.
1093
1094 Support --bridge-interface on all platforms, not just BSD.
1095
1096 Added support for advanced PXE functions. It's now
1097 possible to define a prompt and menu options which will
1098 be displayed when a client PXE boots. It's also possible to
1099 hand-off booting to other boot servers. Proxy-DHCP, where
1100 dnsmasq just supplies the PXE information and another DHCP
1101 server does address allocation, is also allowed. See the
1102 --pxe-prompt and --pxe-service keywords. Thanks to
1103 Alkis Georgopoulos for the suggestion and Guilherme Moro
1104 and Michael Brown for assistance.
1105
1106 Improvements to DHCP logging. Thanks to Tom Metro for
1107 useful suggestions.
1108
1109 Add ability to build dnsmasq without DHCP support. To do
1110 this, edit src/config.h or build with
1111 "make COPTS=-DNO_DHCP". Thanks to Mahavir Jain for the patch.
1112
1113 Added --test command-line switch - syntax check
1114 configuration files only.
1115
1116 Updated French translation. Thanks to Gildas Le Nadan.
1117
1118
1119 version 2.47
1120 Updated French translation. Thanks to Gildas Le Nadan.
1121
1122 Fixed interface enumeration code to work on NetBSD
1123 5.0. Thanks to Roy Marples for the patch.
1124
1125 Updated config.h to use the same location for the lease
1126 file on NetBSD as the other *BSD variants. Also allow
1127 LEASEFILE and CONFFILE symbols to be overriden in CFLAGS.
1128
1129 Handle duplicate address detection on IPv6 more
1130 intelligently. In IPv6, an interface can have an address
1131 which is not usable, because it is still undergoing DAD
1132 (such addresses are marked "tentative"). Attempting to
1133 bind to an address in this state returns an error,
1134 EADDRNOTAVAIL. Previously, on getting such an error,
1135 dnsmasq would silently abandon the address, and never
1136 listen on it. Now, it retries once per second for 20
1137 seconds before generating a fatal error. 20 seconds should
1138 be long enough for any DAD process to complete, but can be
1139 adjusted in src/config.h if necessary. Thanks to Martin
1140 Krafft for the bug report.
1141
1142 Add DBus introspection. Patch from Jeremy Laine.
1143
1144 Update Dbus configuration file. Patch from Colin Walters.
1145 Fix for this bug:
1146 http://bugs.freedesktop.org/show_bug.cgi?id=18961
1147
1148 Support arbitrarily encapsulated DHCP options, suggestion
1149 and initial patch from Samium Gromoff. This is useful for
1150 (eg) gPXE, which expect all its private options to be
1151 encapsulated inside a single option 175. So, eg,
1152
1153 dhcp-option = encap:175, 190, "iscsi-client0"
1154 dhcp-option = encap:175, 191, "iscsi-client0-secret"
1155
1156 will provide iSCSI parameters to gPXE.
1157
1158 Enhance --dhcp-match to allow testing of the contents of a
1159 client-sent option, as well as its presence. This
1160 application in mind for this is RFC 4578
1161 client-architecture specifiers, but it's generally useful.
1162 Joey Korkames suggested the enhancement.
1163
1164 Move from using the IP_XMIT_IF ioctl to IP_BOUND_IF on
1165 OpenSolaris. Thanks to Bastian Machek for the heads-up.
1166
1167 No longer complain about blank lines in
1168 /etc/ethers. Thanks to Jon Nelson for the patch.
1169
1170 Fix binding of servers to physical devices, eg
1171 --server=/domain/1.2.3.4@eth0 which was broken from 2.43
1172 onwards unless --query-port=0 set. Thanks to Peter Naulls
1173 for the bug report.
1174
1175 Reply to DHCPINFORM requests even when the supplied ciaddr
1176 doesn't fall in any dhcp-range. In this case it's not
1177 possible to supply a complete configuration, but
1178 individually-configured options (eg PAC) may be useful.
1179
1180 Allow the source address of an alias to be a range:
1181 --alias=192.168.0.0,10.0.0.0,255.255.255.0 maps the whole
1182 subnet 192.168.0.0->192.168.0.255 to 10.0.0.0->10.0.0.255,
1183 as before.
1184 --alias=192.168.0.10-192.168.0.40,10.0.0.0,255.255.255.0
1185 maps only the 192.168.0.10->192.168.0.40 region. Thanks to
1186 Ib Uhrskov for the suggestion.
1187
1188 Don't dynamically allocate DHCP addresses which may break
1189 Windows. Addresses which end in .255 or .0 are broken in
1190 Windows even when using supernetting.
1191 --dhcp-range=192.168.0.1,192.168.1.254,255,255,254.0 means
1192 192.168.0.255 is a valid IP address, but not for Windows.
1193 See Microsoft KB281579. We therefore no longer allocate
1194 these addresses to avoid hard-to-diagnose problems.
1195
1196 Update Polish translation. Thanks to Jan Psota.
1197
1198 Delete the PID-file when dnsmasq shuts down. Note that by
1199 this time, dnsmasq is normally not running as root, so
1200 this will fail if the PID-file is stored in a root-owned
1201 directory; such failure is silently ignored. To take
1202 advantage of this feature, the PID-file must be stored in a
1203 directory owned and write-able by the user running
1204 dnsmasq.
1205
1206
1207 version 2.46
1208 Allow --bootp-dynamic to take a netid tag, so that it may
1209 be selectively enabled. Thanks to Olaf Westrik for the
1210 suggestion.
1211
1212 Remove ISC-leasefile reading code. This has been
1213 deprecated for a long time, and last time I removed it, it
1214 ended up going back by request of one user. This time,
1215 it's gone for good; otherwise it would need to be
1216 re-worked to support multiple domains (see below).
1217
1218 Support DHCP clients in multiple DNS domains. This is a
1219 long-standing request. Clients are assigned to a domain
1220 based in their IP address.
1221
1222 Add --dhcp-fqdn flag, which changes behaviour if DNS names
1223 assigned to DHCP clients. When this is set, there must be
1224 a domain associated with each client, and only
1225 fully-qualified domain names are added to the DNS. The
1226 advantage is that the only the FQDN needs to be unique,
1227 so that two or more DHCP clients can share a hostname, as
1228 long as they are in different domains.
1229
1230 Set environment variable DNSMASQ_DOMAIN when invoking
1231 lease-change script. This may be useful information to
1232 have now that it's variable.
1233
1234 Tighten up data-checking code for DNS packet
1235 handling. Thanks to Steve Dodd who found certain illegal
1236 packets which could crash dnsmasq. No memory overwrite was
1237 possible, so this is not a security issue beyond the DoS
1238 potential.
1239
1240 Update example config dhcp option 47, the previous
1241 suggestion generated an illegal, zero-length,
1242 option. Thanks to Matthias Andree for finding this.
1243
1244 Rewrite hosts-file reading code to remove the limit of
1245 1024 characters per line. John C Meuser found this.
1246
1247 Create a net-id tag with the name of the interface on
1248 which the DHCP request was received.
1249
1250 Fixed minor memory leak in DBus code, thanks to Jeremy
1251 Laine for the patch.
1252
1253 Emit DBus signals as the DHCP lease database
1254 changes. Thanks to Jeremy Laine for the patch.
1255
1256 Allow for more that one MAC address in a dhcp-host
1257 line. This configuration tells dnsmasq that it's OK to
1258 abandon a DHCP lease of the fixed address to one MAC
1259 address, if another MAC address in the dhcp-host statement
1260 asks for an address. This is useful to give a fixed
1261 address to a host which has two network interfaces
1262 (say, a laptop with wired and wireless interfaces.)
1263 It's very important to ensure that only one interface
1264 at a time is up, since dnsmasq abandons the first lease
1265 and re-uses the address before the leased time has
1266 elapsed. John Gray suggested this.
1267
1268 Tweak the response to a DHCP request packet with a wrong
1269 server-id when --dhcp-authoritative is set; dnsmasq now
1270 returns a DHCPNAK, rather than silently ignoring the
1271 packet. Thanks to Chris Marget for spotting this
1272 improvement.
1273
1274 Add --cname option. This provides a limited alias
1275 function, usable for DHCP names. Thanks to AJ Weber for
1276 suggestions on this.
1277
1278 Updated contrib/webmin with latest version from Neil
1279 Fisher.
1280
1281 Updated Polish translation. Thanks to Jan Psota.
1282
1283 Correct the text names for DHCP options 64 and 65 to be
1284 "nis+-domain" and "nis+-servers".
1285
1286 Updated Spanish translation. Thanks to Chris Chatham.
1287
1288 Force re-reading of /etc/resolv.conf when an "interface
1289 up" event occurs.
1290
1291
1292 version 2.45
1293 Fix total DNS failure in release 2.44 unless --min-port
1294 specified. Thanks to Steven Barth and Grant Coady for
1295 bugreport. Also reject out-of-range port spec, which could
1296 break things too: suggestion from Gilles Espinasse.
1297
1298
1299 version 2.44
1300 Fix crash when unknown client attempts to renew a DHCP
1301 lease, problem introduced in version 2.43. Thanks to
1302 Carlos Carvalho for help chasing this down.
1303
1304 Fix potential crash when a host which doesn't have a lease
1305 does DHCPINFORM. Again introduced in 2.43. This bug has
1306 never been reported in the wild.
1307
1308 Fix crash in netlink code introduced in 2.43. Thanks to
1309 Jean Wolter for finding this.
1310
1311 Change implementation of min_port to work even if min-port
1312 is large.
1313
1314 Patch to enable compilation of latest Mac OS X. Thanks to
1315 David Gilman.
1316
1317 Update Spanish translation. Thanks to Christopher Chatham.
1318
1319
1320 version 2.43
1321 Updated Polish translation. Thanks to Jan Psota.
1322
1323 Flag errors when configuration options are repeated
1324 illegally.
1325
1326 Further tweaks for GNU/kFreeBSD
1327
1328 Add --no-wrap to msgmerge call - provides nicer .po file
1329 format.
1330
1331 Honour lease-time spec in dhcp-host lines even for
1332 BOOTP. The user is assumed to known what they are doing in
1333 this case. (Hosts without the time spec still get infinite
1334 leases for BOOTP, over-riding the default in the
1335 dhcp-range.) Thanks to Peter Katzmann for uncovering this.
1336
1337 Fix problem matching relay-agent ids. Thanks to Michael
1338 Rack for the bug report.
1339
1340 Add --naptr-record option. Suggestion from Johan
1341 Bergquist.
1342
1343 Implement RFC 5107 server-id-override DHCP relay agent
1344 option.
1345
1346 Apply patches from Stefan Kruger for compilation on
1347 Solaris 10 under Sun studio.
1348
1349 Yet more tweaking of Linux capability code, to suppress
1350 pointless wingeing from kernel 2.6.25 and above.
1351
1352 Improve error checking during startup. Previously, some
1353 errors which occurred during startup would be worked
1354 around, with dnsmasq still starting up. Some were logged,
1355 some silent. Now, they all cause a fatal error and dnsmasq
1356 terminates with a non-zero exit code. The errors are those
1357 associated with changing uid and gid, setting process
1358 capabilities and writing the pidfile. Thanks to Uwe
1359 Gansert and the Suse security team for pointing out
1360 this improvement, and Bill Reimers for good implementation
1361 suggestions.
1362
1363 Provide NO_LARGEFILE compile option to switch off largefile
1364 support when compiling against versions of uclibc which
1365 don't support it. Thanks to Stephane Billiart for the patch.
1366
1367 Implement random source ports for interactions with
1368 upstream nameservers. New spoofing attacks have been found
1369 against nameservers which do not do this, though it is not
1370 clear if dnsmasq is vulnerable, since to doesn't implement
1371 recursion. By default dnsmasq will now use a different
1372 source port (and socket) for each query it sends
1373 upstream. This behaviour can suppressed using the
1374 --query-port option, and the old default behaviour
1375 restored using --query-port=0. Explicit source-port
1376 specifications in --server configs are still honoured.
1377
1378 Replace the random number generator, for better
1379 security. On most BSD systems, dnsmasq uses the
1380 arc4random() RNG, which is secure, but on other platforms,
1381 it relied on the C-library RNG, which may be
1382 guessable and therefore allow spoofing. This release
1383 replaces the libc RNG with the SURF RNG, from Daniel
1384 J. Berstein's DJBDNS package.
1385
1386 Don't attempt to change user or group or set capabilities
1387 if dnsmasq is run as a non-root user. Without this, the
1388 change from soft to hard errors when these fail causes
1389 problems for non-root daemons listening on high
1390 ports. Thanks to Patrick McLean for spotting this.
1391
1392 Updated French translation. Thanks to Gildas Le Nadan.
1393
1394
1395 version 2.42
1396 The changelog for version 2.42 and earlier is
1397 available in CHANGELOG.archive.
