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