Log forwarding table overflows.
[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
54 version 2.66
55 Add the ability to act as an authoritative DNS
56 server. Dnsmasq can now answer queries from the wider 'net
57 with local data, as long as the correct NS records are set
58 up. Only local data is provided, to avoid creating an open
59 DNS relay. Zone transfer is supported, to allow secondary
60 servers to be configured.
61
62 Add "constructed DHCP ranges" for DHCPv6. This is intended
63 for IPv6 routers which get prefixes dynamically via prefix
64 delegation. With suitable configuration, stateful DHCPv6
65 and RA can happen automatically as prefixes are delegated
66 and then deprecated, without having to re-write the
67 dnsmasq configuration file or restart the daemon. Thanks to
68 Steven Barth for extensive testing and development work on
69 this idea.
70
71 Fix crash on startup on Solaris 11. Regression probably
72 introduced in 2.61. Thanks to Geoff Johnstone for the
73 patch.
74
75 Add code to make behaviour for TCP DNS requests that same
76 as for UDP requests, when a request arrives for an allowed
77 address, but via a banned interface. This change is only
78 active on Linux, since the relevant API is missing (AFAIK)
79 on other platforms. Many thanks to Tomas Hozza for
80 spotting the problem, and doing invaluable discovery of
81 the obscure and undocumented API required for the solution.
82
83 Don't send the default DHCP option advertising dnsmasq as
84 the local DNS server if dnsmasq is configured to not act
85 as DNS server, or it's configured to a non-standard port.
86
87 Add DNSMASQ_CIRCUIT_ID, DNSMASQ_SUBCRIBER_ID,
88 DNSMASQ_REMOTE_ID variables to the environment of the
89 lease-change script (and the corresponding Lua). These hold
90 information inserted into the DHCP request by a DHCP relay
91 agent. Thanks to Lakefield Communications for providing a
92 bounty for this addition.
93
94 Fixed crash, introduced in 2.64, whilst handling DHCPv6
95 information-requests with some common configurations.
96 Thanks to Robert M. Albrecht for the bug report and
97 chasing the problem.
98
99 Add --ipset option. Thanks to Jason A. Donenfeld for the
100 patch.
101
102 Don't erroneously reject some option names in --dhcp-match
103 options. Thanks to Benedikt Hochstrasser for the bug report.
104
105 Allow a trailing '*' wildcard in all interface-name
106 configurations. Thanks to Christian Parpart for the patch.
107
108 Handle the situation where libc headers define
109 SO_REUSEPORT, but the kernel in use doesn't, to cope with
110 the introduction of this option to Linux. Thanks to Rich
111 Felker for the bug report.
112
113 Update Polish translation. Thanks to Jan Psota.
114
115 Fix crash if the configured DHCP lease limit is
116 reached. Regression occurred in 2.61. Thanks to Tsachi for
117 the bug report.
118
119 Update the French translation. Thanks to Gildas le Nadan.
120
121
122 version 2.65
123 Fix regression which broke forwarding of queries sent via
124 TCP which are not for A and AAAA and which were directed to
125 non-default servers. Thanks to Niax for the bug report.
126
127 Fix failure to build with DHCP support excluded. Thanks to
128 Gustavo Zacarias for the patch.
129
130 Fix nasty regression in 2.64 which completely broke cacheing.
131
132
133 version 2.64
134 Handle DHCP FQDN options with all flag bits zero and
135 --dhcp-client-update set. Thanks to Bernd Krumbroeck for
136 spotting the problem.
137
138 Finesse the check for /etc/hosts names which conflict with
139 DHCP names. Previously a name/address pair in /etc/hosts
140 which didn't match the name/address of a DHCP lease would
141 generate a warning. Now that only happesn if there is not
142 also a match. This allows multiple addresses for a name in
143 /etc/hosts with one of them assigned via DHCP.
144
145 Fix broken vendor-option processing for BOOTP. Thanks to
146 Hans-Joachim Baader for the bug report.
147
148 Don't report spurious netlink errors, regression in
149 2.63. Thanks to Vladislav Grishenko for the patch.
150
151 Flag DHCP or DHCPv6 in starup logging. Thanks to
152 Vladislav Grishenko for the patch.
153
154 Add SetServersEx method in DBus interface. Thanks to Dan
155 Williams for the patch.
156
157 Add SetDomainServers method in DBus interface. Thanks to
158 Roy Marples for the patch.
159
160 Fix build with later Lua libraries. Thansk to Cristian
161 Rodriguez for the patch.
162
163 Add --max-cache-ttl option. Thanks to Dennis Kaarsemaker
164 for the patch.
165
166 Fix breakage of --host-record parsing, resulting in
167 infinte loop at startup. Regression in 2.63. Thanks to
168 Haim Gelfenbeyn for spotting this.
169
170 Set SO_REUSEADDRESS and SO_V6ONLY options on the DHCPv6
171 socket, this allows multiple instances of dnsmasq on a
172 single machine, in the same way as for DHCPv4. Thanks to
173 Gene Czarcinski and Vladislav Grishenko for work on this.
174
175 Fix DHCPv6 to do access control correctly when it's
176 configured with --listen-address. Thanks to
177 Gene Czarcinski for sorting this out.
178
179 Add a "wildcard" dhcp-range which works for any IPv6
180 subnet, --dhcp-range=::,static Useful for Stateless
181 DHCPv6. Thanks to Vladislav Grishenko for the patch.
182
183 Don't include lease-time in DHCPACK replies to DHCPINFORM
184 queries, since RFC-2131 says we shouldn't. Thanks to
185 Wouter Ibens for pointing this out.
186
187 Makefile tweak to do dependency checking on header files.
188 Thanks to Johan Peeters for the patch.
189
190 Check interface for outgoing unsolicited router
191 advertisements, rather than relying on interface address
192 configuration. Thanks to Gene Czarinski for the patch.
193
194 Handle better attempts to transmit on interfaces which are
195 still doing DAD, and specifically do not just transmit
196 without setting source address and interface, since this
197 can cause very puzzling effects when a router
198 advertisement goes astray. Thanks again to Gene Czarinski.
199
200 Get RA timers right when there is more than one
201 dhcp-range on a subnet.
202
203
204 version 2.63
205 Do duplicate dhcp-host address check in --test mode.
206
207 Check that tftp-root directories are accessible before
208 start-up. Thanks to Daniel Veillard for the initial patch.
209
210 Allow more than one --tfp-root flag. The per-interface
211 stuff is pointless without that.
212
213 Add --bind-dynamic. A hybrid mode between the default and
214 --bind-interfaces which copes with dynamically created
215 interfaces.
216
217 A couple of fixes to the build system for Android. Thanks
218 to Metin Kaya for the patches.
219
220 Remove the interface:<interface> argument in --dhcp-range, and
221 the interface argument to --enable-tftp. These were a
222 still-born attempt to allow automatic isolated
223 configuration by libvirt, but have never (to my knowledge)
224 been used, had very strange semantics, and have been
225 superceded by other mechanisms.
226
227 Fixed bug logging filenames when duplicate dhcp-host
228 addresses are found. Thanks to John Hanks for the patch.
229
230 Fix regression in 2.61 which broke caching of CNAME
231 chains. Thanks to Atul Gupta for the bug report.
232
233 Allow the target of a --cname flag to be another --cname.
234
235 Teach DHCPv6 about the RFC 4242 information-refresh-time
236 option, and add parsing if the minutes, hours and days
237 format for options. Thanks to Francois-Xavier Le Bail for
238 the suggestion.
239
240 Allow "w" (for week) as multiplier in lease times, as well
241 as seconds, minutes, hours and days. Álvaro Gámez Machado
242 spotted the ommission.
243
244 Update French translation. Thanks to Gildas Le Nadan.
245
246 Allow a DBus service name to be given with --enable-dbus
247 which overrides the default,
248 uk.org.thekelleys.dnsmasq. Thanks to Mathieu
249 Trudel-Lapierre for the patch.
250
251 Set the "prefix on-link" bit in Router
252 Advertisements. Thanks to Gui Iribarren for the patch.
253
254
255 version 2.62
256 Update German translation. Thanks to Conrad Kostecki.
257
258 Cope with router-solict packets wich don't have a valid
259 source address. Thanks to Vladislav Grishenko for the patch.
260
261 Fixed bug which caused missing periodic router
262 advertisements with some configurations. Thanks to
263 Vladislav Grishenko for the patch.
264
265 Fixed bug which broke DHCPv6/RA with prefix lengths
266 which are not divisible by 8. Thanks to Andre Coetzee
267 for spotting this.
268
269 Fix non-response to router-solicitations when
270 router-advertisement configured, but DHCPv6 not
271 configured. Thanks to Marien Zwart for the patch.
272
273 Add --dns-rr, to allow arbitrary DNS resource records.
274
275 Fixed bug which broke RA scheduling when an interface had
276 two addresses in the same network. Thanks to Jim Bos for
277 his help nailing this.
278
279 version 2.61
280 Re-write interface discovery code on *BSD to use
281 getifaddrs. This is more portable, more straightforward,
282 and allows us to find the prefix length for IPv6
283 addresses.
284
285 Add ra-names, ra-stateless and slaac keywords for DHCPv6.
286 Dnsmasq can now synthesise AAAA records for dual-stack
287 hosts which get IPv6 addresses via SLAAC. It is also now
288 possible to use SLAAC and stateless DHCPv6, and to
289 tell clients to use SLAAC addresses as well as DHCP ones.
290 Thanks to Dave Taht for help with this.
291
292 Add --dhcp-duid to allow DUID-EN uids to be used.
293
294 Explicity send DHCPv6 replies to the correct port, instead
295 of relying on clients to send requests with the correct
296 source address, since at least one client in the wild gets
297 this wrong. Thanks to Conrad Kostecki for help tracking
298 this down.
299
300 Send a preference value of 255 in DHCPv6 replies when
301 --dhcp-authoritative is in effect. This tells clients not
302 to wait around for other DHCP servers.
303
304 Better logging of DHCPv6 options.
305
306 Add --host-record. Thanks to Rob Zwissler for the
307 suggestion.
308
309 Invoke the DHCP script with action "tftp" when a TFTP file
310 transfer completes. The size of the file, address to which
311 it was sent and complete pathname are supplied. Note that
312 version 2.60 introduced some script incompatibilties
313 associated with DHCPv6, and this is a further change. To
314 be safe, scripts should ignore unknown actions, and if
315 not IPv6-aware, should exit if the environment
316 variable DNSMASQ_IAID is set. The use-case for this is
317 to track netboot/install. Suggestion from Shantanu
318 Gadgil.
319
320 Update contrib/port-forward/dnsmasq-portforward to reflect
321 the above.
322
323 Set the environment variable DNSMASQ_LOG_DHCP when running
324 the script id --log-dhcp is in effect, so that script can
325 taylor their logging verbosity. Suggestion from Malte
326 Forkel.
327
328 Arrange that addresses specified with --listen-address
329 work even if there is no interface carrying the
330 address. This is chiefly useful for IPv4 loopback
331 addresses, where any address in 127.0.0.0/8 is a valid
332 loopback address, but normally only 127.0.0.1 appears on
333 the lo interface. Thanks to Mathieu Trudel-Lapierre for
334 the idea and initial patch.
335
336 Fix crash, introduced in 2.60, when a DHCPINFORM is
337 received from a network which has no valid dhcp-range.
338 Thanks to Stephane Glondu for the bug report.
339
340 Add a new DHCP lease time keyword, "deprecated" for
341 --dhcp-range. This is only valid for IPv6, and sets the
342 preffered lease time for both DHCP and RA to zero. The
343 effect is that clients can continue to use the address
344 for existing connections, but new connections will use
345 other addresses, if they exist. This makes hitless
346 renumbering at least possible.
347
348 Fix bug in address6_available() which caused DHCPv6 lease
349 aquisition to fail if more than one dhcp-range in use.
350
351 Provide RDNSS and DNSSL data in router advertisements,
352 using the settings provided for DHCP options
353 option6:domain-search and option6:dns-server.
354
355 Tweak logo/favicon.ico to add some transparency. Thanks to
356 SamLT for work on this.
357
358 Don't cache data from non-recursive nameservers, since it
359 may erroneously look like a valid CNAME to a non-exitant
360 name. Thanks to Ben Winslow for finding this.
361
362 Call SO_BINDTODEVICE on the DHCP socket(s) when doing DHCP
363 on exactly one interface and --bind-interfaces is set. This
364 makes the OpenStack use-case of one dnsmasq per virtual
365 interface work. This is only available on Linux; it's not
366 supported on other platforms. Thanks to Vishvananda Ishaya
367 and the OpenStack team for the suggestion.
368
369 Updated French translation. Thanks to Gildas Le Nadan.
370
371 Give correct from-cache answers to explict CNAME queries.
372 Thanks to Rob Zwissler for spotting this.
373
374 Add --tftp-lowercase option. Thanks to Oliver Rath for the
375 patch.
376
377 Ensure that the DBus DhcpLeaseUpdated events are generated
378 when a lease goes through INIT_REBOOT state, even if the
379 dhcp-script is not in use. Thanks to Antoaneta-Ecaterina
380 Ene for the patch.
381
382 Fix failure of TFTP over IPv4 on OpenBSD platform. Thanks
383 to Brad Smith for spotting this.
384
385
386 version 2.60
387 Fix compilation problem in Mac OS X Lion. Thanks to Olaf
388 Flebbe for the patch.
389
390 Fix DHCP when using --listen-address with an IP address
391 which is not the primary address of an interface.
392
393 Add --dhcp-client-update option.
394
395 Add Lua integration. Dnsmasq can now execute a DHCP
396 lease-change script written in Lua. This needs to be
397 enabled at compile time by setting HAVE_LUASCRIPT in
398 src/config.h or running "make COPTS=-DHAVE_LUASCRIPT"
399 Thanks to Jan-Piet Mens for the idea and proof-of-concept
400 implementation.
401
402 Tidied src/config.h to distinguish between
403 platform-dependent compile-time options which are selected
404 automatically, and builder-selectable compile time
405 options. Document the latter better, and describe how to
406 set them from the make command line.
407
408 Tidied up IPPROTO_IP/SOL_IP (and IPv6 equivalent)
409 confusion. IPPROTO_IP works everywhere now.
410
411 Set TOS on DHCP sockets, this improves things on busy
412 wireless networks. Thanks to Dave Taht for the patch.
413
414 Determine VERSION automatically based on git magic:
415 release tags or hash values.
416
417 Improve start-up speed when reading large hosts files
418 containing many distinct addresses.
419
420 Fix problem if dnsmasq is started without the stdin,
421 stdout and stderr file descriptors open. This can manifest
422 itself as 100% CPU use. Thanks to Chris Moore for finding
423 this.
424
425 Fix shell-scripting bug in bld/pkg-wrapper. Thanks to
426 Mark Mitchell for the patch.
427
428 Allow the TFP server or boot server in --pxe-service, to
429 be a domain name instead of an IP address. This allows for
430 round-robin to multiple servers, in the same way as
431 --dhcp-boot. A good suggestion from Cristiano Cumer.
432
433 Support BUILDDIR variable in the Makefile. Allows builds
434 for multiple archs from the same source tree with eg.
435 make BUILDDIR=linux (relative to dnsmasq tree)
436 make BUILDDIR=/tmp/openbsd (absolute path)
437 If BUILDDIR is not set, compilation happens in the src
438 directory, as before. Suggestion from Mark Mitchell.
439
440 Support DHCPv6. Support is there for the sort of things
441 the existing v4 server does, including tags, options,
442 static addresses and relay support. Missing is prefix
443 delegation, which is probably not required in the dnsmasq
444 niche, and an easy way to accept prefix delegations from
445 an upstream DHCPv6 server, which is. Future plans include
446 support for DHCPv6 router option and MAC address option
447 (to make selecting clients by MAC address work like IPv4).
448 These will be added as the standards mature.
449 This code has been tested, but this is the first release,
450 so don't bet the farm on it just yet. Many thanks to all
451 testers who have got it this far.
452
453 Support IPv6 router advertisements. This is a
454 simple-minded implementation, aimed at providing the
455 vestigial RA needed to go alongside IPv6. Is picks up
456 configuration from the DHCPv6 conf, and should just need
457 enabling with --enable-ra.
458
459 Fix long-standing wrinkle with --localise-queries that
460 could result in wrong answers when DNS packets arrive
461 via an interface other than the expected one. Thanks to
462 Lorenzo Milesi and John Hanks for spotting this one.
463
464 Update French translation. Thanks to Gildas Le Nadan.
465
466 Update Polish translation. Thanks to Jan Psota.
467
468
469 version 2.59
470 Fix regression in 2.58 which caused failure to start up
471 with some combinations of dnsmasq config and IPv6 kernel
472 network config. Thanks to Brielle Bruns for the bug
473 report.
474
475 Improve dnsmasq's behaviour when network interfaces are
476 still doing duplicate address detection (DAD). Previously,
477 dnsmasq would wait up to 20 seconds at start-up for the
478 DAD state to terminate. This is broken for bridge
479 interfaces on recent Linux kernels, which don't start DAD
480 until the bridge comes up, and so can take arbitrary
481 time. The new behaviour lets dnsmasq poll for an arbitrary
482 time whilst providing service on other interfaces. Thanks
483 to Stephen Hemminger for pointing out the problem.
484
485
486 version 2.58
487 Provide a definition of the SA_SIZE macro where it's
488 missing. Fixes build failure on openBSD.
489
490 Don't include a zero terminator at the end of messages
491 sent to /dev/log when /dev/log is a datagram socket.
492 Thanks to Didier Rabound for spotting the problem.
493
494 Add --dhcp-sequential-ip flag, to force allocation of IP
495 addresses in ascending order. Note that the default
496 pseudo-random mode is in general better but some
497 server-deployment applications need this.
498
499 Fix problem where a server-id of 0.0.0.0 is sent to a
500 client when a dhcp-relay is in use if a client renews a
501 lease after dnsmasq restart and before any clients on the
502 subnet get a new lease. Thanks to Mike Ruiz for assistance
503 in chasing this one down.
504
505 Don't return NXDOMAIN to an AAAA query if we have CNAME
506 which points to an A record only: NODATA is the correct
507 reply in this case. Thanks to Tom Fernandes for spotting
508 the problem.
509
510 Relax the need to supply a netmask in --dhcp-range for
511 networks which use a DHCP relay. Whilst this is still
512 desireable, in the absence of a netmask dnsmasq will use
513 a default based on the class (A, B, or C) of the address.
514 This should at least remove a cause of mysterious failure
515 for people using RFC1918 addresses and relays.
516
517 Add support for Linux conntrack connection marking. If
518 enabled with --conntrack, the connection mark for incoming
519 DNS queries will be copied to the outgoing connections
520 used to answer those queries. This allows clever firewall
521 and accounting stuff. Only available if dnsmasq is
522 compiled with HAVE_CONNTRACK and adds a dependency on
523 libnetfilter-conntrack. Thanks to Ed Wildgoose for the
524 initial idea, testing and sponsorship of this function.
525
526 Provide a sane error message when someone attempts to
527 match a tag in --dhcp-host.
528
529 Tweak the behaviour of --domain-needed, to avoid problems
530 with recursive nameservers downstream of dnsmasq. The new
531 behaviour only stops A and AAAA queries, and returns
532 NODATA rather than NXDOMAIN replies.
533
534 Efficiency fix for very large DHCP configurations, thanks
535 to James Gartrell and Mike Ruiz for help with this.
536
537 Allow the TFTP-server address in --dhcp-boot to be a
538 domain-name which is looked up in /etc/hosts. This can
539 give multiple IP addresses which are used round-robin,
540 thus doing TFTP server load-balancing. Thanks to Sushil
541 Agrawal for the patch.
542
543 When two tagged dhcp-options for a particular option
544 number are both valid, use the one which is valid without
545 a tag from the dhcp-range. Allows overriding of the value
546 of a DHCP option for a particular host as well as
547 per-network values. So
548 --dhcp-range=set:interface1,......
549 --dhcp-host=set:myhost,.....
550 --dhcp-option=tag:interface1,option:nis-domain,"domain1"
551 --dhcp-option=tag:myhost,option:nis-domain,"domain2"
552 will set the NIS-domain to domain1 for hosts in the range, but
553 override that to domain2 for a particular host.
554
555 Fix bug which resulted in truncated files and timeouts for
556 some TFTP transfers. The bug only occurs with netascii
557 transfers and needs an unfortunate relationship between
558 file size, blocksize and the number of newlines in the
559 last block before it manifests itself. Many thanks to
560 Alkis Georgopoulos for spotting the problem and providing
561 a comprehensive test-case.
562
563 Fix regression in TFTP server on *BSD platforms introduced
564 in version 2.56, due to confusion with sockaddr
565 length. Many thanks to Loic Pefferkorn for finding this.
566
567 Support scope-ids in IPv6 addresses of nameservers from
568 /etc/resolv.conf and in --server options. Eg
569 nameserver fe80::202:a412:4512:7bbf%eth0 or
570 server=fe80::202:a412:4512:7bbf%eth0. Thanks to
571 Michael Stapelberg for the suggestion.
572
573 Update Polish translation, thanks to Jan Psota.
574
575 Update French translation. Thanks to Gildas Le Nadan.
576
577
578 version 2.57
579 Add patches to allow build under Android.
580
581 Provide our own header for the DNS protocol, rather than
582 relying on arpa/nameser.h. This has proved more or less
583 defective over the years and the final straw is that it's
584 effectively empty on Android.
585
586 Fix regression in 2.56 which caused hex constants in
587 configuration to be rejected if they contain the '*'
588 wildcard.
589
590 Correct wrong casts of arguments to ctype.h functions,
591 isdigit(), isxdigit() etc. Thanks to Matthias Andree for
592 spotting this.
593
594 Allow build with IDN support independently from i18n.
595 IDN support continues to be included automatically
596 when i18n is included.
597 'make COPTS=-DHAVE_IDN' is the magic incantation.
598
599 Modify check on extraneous command line junk (added in
600 2.56) so that it doesn't complain about extra _empty_
601 arguments. Otherwise this breaks libvirt.
602
603
604 version 2.56
605 Add a patch to allow dnsmasq to get interface names right in a
606 Solaris zone. Thanks to Dj Padzensky for this.
607
608 Improve data-type parsing heuristics so that
609 --dhcp-option=option:domain-search,.
610 treats the value as a string and not an IP address.
611 Thanks to Clemens Fischer for spotting that.
612
613 Add IPv6 support to the TFTP server. Many thanks to Jan
614 'RedBully' Seiffert for the patches.
615
616 Log DNS queries at level LOG_INFO, rather then
617 LOG_DEBUG. This makes things consistent with DHCP
618 logging. Thanks to Adam Pribyl for spotting the problem.
619
620 Ensure that dnsmasq terminates cleanly when using
621 --syslog-async even if it cannot make a connection to the
622 syslogd.
623
624 Add --add-mac option. This is to support currently
625 experimental DNS filtering facilities. Thanks to Benjamin
626 Petrin for the orignal patch.
627
628 Fix bug which meant that tags were ignored in dhcp-range
629 configuration specifying PXE-proxy service. Thanks to
630 Cristiano Cumer for spotting this.
631
632 Raise an error if there is extra junk, not part of an
633 option, on the command line.
634
635 Flag a couple of log messages in cache.c as coming from
636 the DHCP subsystem. Thanks to Olaf Westrik for the patch.
637
638 Omit timestamps from logs when a) logging to stderr and
639 b) --keep-in-forground is set. The logging facility on the
640 other end of stderr can be assumned to supply them. Thanks
641 to John Hallam for the patch.
642
643 Don't complain about strings longer than 255 characters in
644 --txt-record, just split the long strings into 255
645 character chunks instead.
646
647 Fix crash on double-free. This bug can only happen when
648 dhcp-script is in use and then only in rare circumstances
649 triggered by high DHCP transaction rate and a slow
650 script. Thanks to Ferenc Wagner for finding the problem.
651
652 Only log that a file has been sent by TFTP after the
653 transfer has completed succesfully.
654
655 A good suggestion from Ferenc Wagner: extend
656 the --domain option to allow this sort of thing:
657 --domain=thekelleys.org.uk,192.168.0.0/24,local
658 which automatically creates
659 --local=/thekelleys.org.uk/
660 --local=/0.168.192.in-addr.arpa/
661
662 Tighten up syntax checking of hex contants in the config
663 file. Thanks to Fred Damen for spotting this.
664
665 Add dnsmasq logo/icon, contributed by Justin Swift. Many
666 thanks for that.
667
668 Never cache DNS replies which have the 'cd' bit set, or
669 which result from queries forwarded with the 'cd' bit
670 set. The 'cd' bit instructs a DNSSEC validating server
671 upstream to ignore signature failures and return replies
672 anyway. Without this change it's possible to pollute the
673 dnsmasq cache with bad data by making a query with the
674 'cd' bit set and subsequent queries would return this data
675 without its being marked as suspect. Thanks to Anders
676 Kaseorg for pointing out this problem.
677
678 Add --proxy-dnssec flag, for compliance with RFC
679 4035. Dnsmasq will now clear the 'ad' bit in answers returned
680 from upstream validating nameservers unless this option is
681 set.
682
683 Allow a filename of "-" for --conf-file to read
684 stdin. Suggestion from Timothy Redaelli.
685
686 Rotate the order of SRV records in replies, to provide
687 round-robin load balancing when all the priorities are
688 equal. Thanks to Peter McKinney for the suggestion.
689
690 Edit
691 contrib/MacOSX-launchd/uk.org.thekelleys.dnsmasq.plist
692 so that it doesn't log all queries to a file by
693 default. Thanks again to Peter McKinney.
694
695 By default, setting an IPv4 address for a domain but not
696 an IPv6 address causes dnsmasq to return
697 an NODATA reply for IPv6 (or vice-versa). So
698 --address=/google.com/1.2.3.4 stops IPv6 queries for
699 *google.com from being forwarded. Make it possible to
700 override this behaviour by defining the sematics if the
701 same domain appears in both --server and --address.
702 In that case, the --address has priority for the address
703 family in which is appears, but the --server has priority
704 of the address family which doesn't appear in --adddress
705 So:
706 --address=/google.com/1.2.3.4
707 --server=/google.com/#
708 will return 1.2.3.4 for IPv4 queries for *.google.com but
709 forward IPv6 queries to the normal upstream nameserver.
710 Similarly when setting an IPv6 address
711 only this will allow forwarding of IPv4 queries. Thanks to
712 William for pointing out the need for this.
713
714 Allow more than one --dhcp-optsfile and --dhcp-hostsfile
715 and make them understand directories as arguments in the
716 same way as --addn-hosts. Suggestion from John Hanks.
717
718 Ignore rebinding requests for leases we don't know
719 about. Rebind is broadcast, so we might get to overhear a
720 request meant for another DHCP server. NAKing this is
721 wrong. Thanks to Brad D'Hondt for assistance with this.
722
723 Fix cosmetic bug which produced strange output when
724 dumping cache statistics with some configurations. Thanks
725 to Fedor Kozhevnikov for spotting this.
726
727
728 version 2.55
729 Fix crash when /etc/ethers is in use. Thanks to
730 Gianluigi Tiesi for finding this.
731
732 Fix crash in netlink_multicast(). Thanks to Arno Wald for
733 finding this one.
734
735 Allow the empty domain "." in dhcp domain-search (119)
736 options.
737
738
739 version 2.54
740 There is no version 2.54 to avoid confusion with 2.53,
741 which incorrectly identifies itself as 2.54.
742
743
744 version 2.53
745 Fix failure to compile on Debian/kFreeBSD. Thanks to
746 Axel Beckert and Petr Salinger.
747
748 Fix code to avoid scary strict-aliasing warnings
749 generated by gcc 4.4.
750
751 Added FAQ entry warning about DHCP failures with Vista
752 when firewalls block 255.255.255.255.
753
754 Fixed bug which caused bad things to happen if a
755 resolv.conf file which exists is subsequently removed.
756 Thanks to Nikolai Saoukh for the patch.
757
758 Rationalised the DHCP tag system. Every configuration item
759 which can set a tag does so by adding "set:<tag>" and
760 every configuration item which is conditional on a tag is
761 made so by "tag:<tag>". The NOT operator changes to '!',
762 which is a bit more intuitive too. Dhcp-host directives
763 can set more than one tag now. The old '#' NOT,
764 "net:" prefix and no-prefixes are still honoured, so
765 no existing config file needs to be changed, but
766 the documentation and new-style config files should be
767 much less confusing.
768
769 Added --tag-if to allow boolean operations on tags.
770 This allows complicated logic to be clearer and more
771 general. A great suggestion from Richard Voigt.
772
773 Add broadcast/unicast information to DHCP logging.
774
775 Allow --dhcp-broadcast to be unconditional.
776
777 Fixed incorrect behaviour with NOT <tag> conditionals in
778 dhcp-options. Thanks to Max Turkewitz for assistance
779 finding this.
780
781 If we send vendor-class encapsulated options based on the
782 vendor-class supplied by the client, and no explicit
783 vendor-class option is given, echo back the vendor-class
784 from the client.
785
786 Fix bug which stopped dnsmasq from matching both a
787 circuitid and a remoteid. Thanks to Ignacio Bravo for
788 finding this.
789
790 Add --dhcp-proxy, which makes it possible to configure
791 dnsmasq to use a DHCP relay agent as a full proxy, with
792 all DHCP messages passing through the proxy. This is
793 useful if the relay adds extra information to the packets
794 it forwards, but cannot be configured with the RFC 5107
795 server-override option.
796
797 Added interface:<iface name> part to dhcp-range. The
798 semantics of this are very odd at first sight, but it
799 allows a single line of the form
800 dhcp-range=interface:virt0,192.168.0.4,192.168.0.200
801 to be added to dnsmasq configuration which then supplies
802 DHCP and DNS services to that interface, without affecting
803 what services are supplied to other interfaces and
804 irrespective of the existance or lack of
805 interface=<interface>
806 lines elsewhere in the dnsmasq configuration. The idea is
807 that such a line can be added automatically by libvirt
808 or equivalent systems, without disturbing any manual
809 configuration.
810
811 Similarly to the above, allow --enable-tftp=<interface>
812
813 Allow a TFTP root to be set separately for requests via
814 different interfaces, --tftp-root=<path>,<interface>
815
816 Correctly handle and log clashes between CNAMES and
817 DNS names being given to DHCP leases. This fixes a bug
818 which caused nonsense IP addresses to be logged. Thanks to
819 Sergei Zhirikov for finding and analysing the problem.
820
821 Tweak flush_log so as to avoid leaving the log
822 file in non-blocking mode. O_NONBLOCK is a property of the
823 file, not the process/descriptor.
824
825 Fix contrib/Solaris10/create_package
826 (/usr/man -> /usr/share/man) Thanks to Vita Batrla.
827
828 Fix a problem where, if a client got a lease, then went
829 to another subnet and got another lease, then moved back,
830 it couldn't resume the old lease, but would instead get
831 a new address. Thanks to Leonardo Rodrigues for spotting
832 this and testing the fix.
833
834 Fix weird bug which sometimes omitted certain characters
835 from the start of quoted strings in dhcp-options. Thanks
836 to Dayton Turner for spotting the problem.
837
838 Add facility to redirect some domains to the standard
839 upstream servers: this allows something like
840 --server=/google.com/1.2.3.4 --server=/www.google.com/#
841 which will send queries for *.google.com to 1.2.3.4,
842 except *www.google.com which will be forwarded as usual.
843 Thanks to AJ Weber for prompting this addition.
844
845 Improve the hash-algorithm used to generate IP addresses
846 from MAC addresses during initial DHCP address
847 allocation. This improves performance when large numbers
848 of hosts with similar MAC addresses all try and get an IP
849 address at the same time. Thanks to Paul Smith for his
850 work on this.
851
852 Tweak DHCP code so that --bridge-interface can be used to
853 select which IP alias of an interface should be used for
854 DHCP purposes on Linux. If eth0 has an alias eth0:dhcp
855 then adding --bridge-interface=eth0:dhcp,eth0 will use
856 the address of eth0:dhcp to determine the correct subnet
857 for DHCP address allocation. Thanks to Pawel Golaszewski
858 for prompting this and Eric Cooper for further testing.
859
860 Add --dhcp-generate-names. Suggestion by Ferenc Wagner.
861
862 Tweak DNS server selection algorithm when there is more
863 than one server available for a domain, eg.
864 --server=/mydomain/1.1.1.1
865 --server=/mydomain/2.2.2.2
866 Thanks to Alberto Cuesta-Canada for spotting a weakness
867 here.
868
869 Add --max-ttl. Thanks to Fredrik Ringertz for the patch.
870
871 Allow --log-facility=- to force all logging to
872 stderr. Suggestion from Clemens Fischer.
873
874 Fix regression which caused configuration like
875 --address=/.domain.com/1.2.3.4 to be rejected. The dot to the
876 left of the domain has been implied and not required for a
877 long time, but it should be accepted for backward
878 compatibility. Thanks to Andrew Burcin for spotting this.
879
880 Add --rebind-domain-ok and --rebind-localhost-ok.
881 Suggestion from Clemens Fischer.
882
883 Log replies to queries of type TXT, when --log-queries
884 is set.
885
886 Fix compiler warnings when compiled with -DNO_DHCP. Thanks
887 to Shantanu Gadgil for the patch.
888
889 Updated French translation. Thanks to Gildas Le Nadan.
890
891 Updated Polish translation. Thanks to Jan Psota.
892
893 Updated German translation. Thanks to Matthias Andree.
894
895 Added contrib/static-arp, thanks to Darren Hoo.
896
897 Fix corruption of the domain when a name from /etc/hosts
898 overrides one supplied by a DHCP client. Thanks to Fedor
899 Kozhevnikov for spotting the problem.
900
901 Updated Spanish translation. Thanks to Chris Chatham.
902
903
904 version 2.52
905 Work around a Linux kernel bug which insists that the
906 length of the option passed to setsockopt must be at least
907 sizeof(int) bytes, even if we're calling SO_BINDTODEVICE
908 and the device name is "lo". Note that this is fixed
909 in kernel 2.6.31, but the workaround is harmless and
910 allows earlier kernels to be used. Also fix dnsmasq
911 bug which reported the wrong address when this failed.
912 Thanks to Fedor for finding this.
913
914 The API for IPv6 PKTINFO changed around Linux kernel
915 2.6.14. Workaround the case where dnsmasq is compiled
916 against newer headers, but then run on an old kernel:
917 necessary for some *WRT distros.
918
919 Re-read the set of network interfaces when re-loading
920 /etc/resolv.conf if --bind-interfaces is not set. This
921 handles the case that loopback interfaces do not exist
922 when dnsmasq is first started.
923
924 Tweak the PXE code to support port 4011. This should
925 reduce broadcasts and make things more reliable when other
926 servers are around. It also improves inter-operability
927 with certain clients.
928
929 Make a pxe-service configuration with no filename or boot
930 service type legal: this does a local boot. eg.
931 pxe-service=x86PC, "Local boot"
932
933 Be more conservative in detecting "A for A"
934 queries. Dnsmasq checks if the name in a type=A query looks
935 like a dotted-quad IP address and answers the query itself
936 if so, rather than forwarding it. Previously dnsmasq
937 relied in the library function inet_addr() to convert
938 addresses, and that will accept some things which are
939 confusing in this context, like 1.2.3 or even just
940 1234. Now we only do A for A processing for four decimal
941 numbers delimited by dots.
942
943 A couple of tweaks to fix compilation on Solaris. Thanks
944 to Joel Macklow for help with this.
945
946 Another Solaris compilation tweak, needed for Solaris
947 2009.06. Thanks to Lee Essen for that.
948
949 Added extract packaging stuff from Lee Essen to
950 contrib/Solaris10.
951
952 Increased the default limit on number of leases to 1000
953 (from 150). This is mainly a defence against DoS attacks,
954 and for the average "one for two class C networks"
955 installation, IP address exhaustion does that just as
956 well. Making the limit greater than the number of IP
957 addresses available in such an installation removes a
958 surprise which otherwise can catch people out.
959
960 Removed extraneous trailing space in the value of the
961 DNSMASQ_TIME_REMAINING DNSMASQ_LEASE_LENGTH and
962 DNSMASQ_LEASE_EXPIRES environment variables. Thanks to
963 Gildas Le Nadan for spotting this.
964
965 Provide the network-id tags for a DHCP transaction to
966 the lease-change script in the environment variable
967 DNSMASQ_TAGS. A good suggestion from Gildas Le Nadan.
968
969 Add support for RFC3925 "Vendor-Identifying Vendor
970 Options". The syntax looks like this:
971 --dhcp-option=vi-encap:<enterprise number>, .........
972
973 Add support to --dhcp-match to allow matching against
974 RFC3925 "Vendor-Identifying Vendor Classes". The syntax
975 looks like this:
976 --dhcp-match=tag,vi-encap<enterprise number>, <value>
977
978 Add some application specific code to assist in
979 implementing the Broadband forum TR069 CPE-WAN
980 specification. The details are in contrib/CPE-WAN/README
981
982 Increase the default DNS packet size limit to 4096, as
983 recommended by RFC5625 section 4.4.3. This can be
984 reconfigured using --edns-packet-max if needed. Thanks to
985 Francis Dupont for pointing this out.
986
987 Rewrite query-ids even for TSIG signed packets, since
988 this is allowed by RFC5625 section 4.5.
989
990 Use getopt_long by default on OS X. It has been supported
991 since version 10.3.0. Thanks to Arek Dreyer for spotting
992 this.
993
994 Added up-to-date startup configuration for MacOSX/launchd
995 in contrib/MacOSX-launchd. Thanks to Arek Dreyer for
996 providing this.
997
998 Fix link error when including Dbus but excluding DHCP.
999 Thanks to Oschtan for the bug report.
1000
1001 Updated French translation. Thanks to Gildas Le Nadan.
1002
1003 Updated Polish translation. Thanks to Jan Psota.
1004
1005 Updated Spanish translation. Thanks to Chris Chatham.
1006
1007 Fixed confusion about domains, when looking up DHCP hosts
1008 in /etc/hosts. This could cause spurious "Ignoring
1009 domain..." messages. Thanks to Fedor Kozhevnikov for
1010 finding and analysing the problem.
1011
1012
1013 version 2.51
1014 Add support for internationalised DNS. Non-ASCII characters
1015 in domain names found in /etc/hosts, /etc/ethers and
1016 /etc/dnsmasq.conf will be correctly handled by translation to
1017 punycode, as specified in RFC3490. This function is only
1018 available if dnsmasq is compiled with internationalisation
1019 support, and adds a dependency on GNU libidn. Without i18n
1020 support, dnsmasq continues to be compilable with just
1021 standard tools. Thanks to Yves Dorfsman for the
1022 suggestion.
1023
1024 Add two more environment variables for lease-change scripts:
1025 First, DNSMASQ_SUPPLIED_HOSTNAME; this is set to the hostname
1026 supplied by a client, even if the actual hostname used is
1027 over-ridden by dhcp-host or dhcp-ignore-names directives.
1028 Also DNSMASQ_RELAY_ADDRESS which gives the address of
1029 a DHCP relay, if used.
1030 Suggestions from Michael Rack.
1031
1032 Fix regression which broke echo of relay-agent
1033 options. Thanks to Michael Rack for spotting this.
1034
1035 Don't treat option 67 as being interchangeable with
1036 dhcp-boot parameters if it's specified as
1037 dhcp-option-force.
1038
1039 Make the code to call scripts on lease-change compile-time
1040 optional. It can be switched off by editing src/config.h
1041 or building with "make COPTS=-DNO_SCRIPT".
1042
1043 Make the TFTP server cope with filenames from Windows/DOS
1044 which use '\' as pathname separator. Thanks to Ralf for
1045 the patch.
1046
1047 Updated Polish translation. Thanks to Jan Psota.
1048
1049 Warn if an IP address is duplicated in /etc/ethers. Thanks
1050 to Felix Schwarz for pointing this out.
1051
1052 Teach --conf-dir to take an option list of file suffices
1053 which will be ignored when scanning the directory. Useful
1054 for backup files etc. Thanks to Helmut Hullen for the
1055 suggestion.
1056
1057 Add new DHCP option named tftpserver-address, which
1058 corresponds to the third argument of dhcp-boot. This
1059 allows the complete functionality of dhcp-boot to be
1060 replicated with dhcp-option. Useful when using
1061 dhcp-optsfile.
1062
1063 Test which upstream nameserver to use every 10 seconds
1064 or 50 queries and not just when a query times out and
1065 is retried. This should improve performance when there
1066 is a slow nameserver in the list. Thanks to Joe for the
1067 suggestion.
1068
1069 Don't do any PXE processing, even for clients with the
1070 correct vendorclass, unless at least one pxe-prompt or
1071 pxe-service option is given. This stops dnsmasq
1072 interfering with proxy PXE subsystems when it is just
1073 the DHCP server. Thanks to Spencer Clark for spotting this.
1074
1075 Limit the blocksize used for TFTP transfers to a value
1076 which avoids packet fragmentation, based on the MTU of the
1077 local interface. Many netboot ROMs can't cope with
1078 fragmented packets.
1079
1080 Honour dhcp-ignore configuration for PXE and proxy-PXE
1081 requests. Thanks to Niels Basjes for the bug report.
1082
1083 Updated French translation. Thanks to Gildas Le Nadan.
1084
1085
1086 version 2.50
1087 Fix security problem which allowed any host permitted to
1088 do TFTP to possibly compromise dnsmasq by remote buffer
1089 overflow when TFTP enabled. Thanks to Core Security
1090 Technologies and Iván Arce, Pablo Hernán Jorge, Alejandro
1091 Pablo Rodriguez, Martín Coco, Alberto Soliño Testa and
1092 Pablo Annetta. This problem has Bugtraq id: 36121
1093 and CVE: 2009-2957
1094
1095 Fix a problem which allowed a malicious TFTP client to
1096 crash dnsmasq. Thanks to Steve Grubb at Red Hat for
1097 spotting this. This problem has Bugtraq id: 36120 and
1098 CVE: 2009-2958
1099
1100
1101 version 2.49
1102 Fix regression in 2.48 which disables the lease-change
1103 script. Thanks to Jose Luis Duran for spotting this.
1104
1105 Log TFTP "file not found" errors. These were not logged,
1106 since a normal PXELinux boot generates many of them, but
1107 the lack of the messages seems to be more confusing than
1108 routinely seeing them when there is no real error.
1109
1110 Update Spanish translation. Thanks to Chris Chatham.
1111
1112
1113 version 2.48
1114 Archived the extensive, backwards, changelog to
1115 CHANGELOG.archive. The current changelog now runs from
1116 version 2.43 and runs conventionally.
1117
1118 Fixed bug which broke binding of servers to physical
1119 interfaces when interface names were longer than four
1120 characters. Thanks to MURASE Katsunori for the patch.
1121
1122 Fixed netlink code to check that messages come from the
1123 correct source, and not another userspace process. Thanks
1124 to Steve Grubb for the patch.
1125
1126 Maintainability drive: removed bug and missing feature
1127 workarounds for some old platforms. Solaris 9, OpenBSD
1128 older than 4.1, Glibc older than 2.2, Linux 2.2.x and
1129 DBus older than 1.1.x are no longer supported.
1130
1131 Don't read included configuration files more than once:
1132 allows complex configuration structures without problems.
1133
1134 Mark log messages from the various subsystems in dnsmasq:
1135 messages from the DHCP subsystem now have the ident string
1136 "dnsmasq-dhcp" and messages from TFTP have ident
1137 "dnsmasq-tftp". Thanks to Olaf Westrik for the patch.
1138
1139 Fix possible infinite DHCP protocol loop when an IP
1140 address nailed to a hostname (not a MAC address) and a
1141 host sometimes provides the name, sometimes not.
1142
1143 Allow --addn-hosts to take a directory: all the files
1144 in the directory are read. Thanks to Phil Cornelius for
1145 the suggestion.
1146
1147 Support --bridge-interface on all platforms, not just BSD.
1148
1149 Added support for advanced PXE functions. It's now
1150 possible to define a prompt and menu options which will
1151 be displayed when a client PXE boots. It's also possible to
1152 hand-off booting to other boot servers. Proxy-DHCP, where
1153 dnsmasq just supplies the PXE information and another DHCP
1154 server does address allocation, is also allowed. See the
1155 --pxe-prompt and --pxe-service keywords. Thanks to
1156 Alkis Georgopoulos for the suggestion and Guilherme Moro
1157 and Michael Brown for assistance.
1158
1159 Improvements to DHCP logging. Thanks to Tom Metro for
1160 useful suggestions.
1161
1162 Add ability to build dnsmasq without DHCP support. To do
1163 this, edit src/config.h or build with
1164 "make COPTS=-DNO_DHCP". Thanks to Mahavir Jain for the patch.
1165
1166 Added --test command-line switch - syntax check
1167 configuration files only.
1168
1169 Updated French translation. Thanks to Gildas Le Nadan.
1170
1171
1172 version 2.47
1173 Updated French translation. Thanks to Gildas Le Nadan.
1174
1175 Fixed interface enumeration code to work on NetBSD
1176 5.0. Thanks to Roy Marples for the patch.
1177
1178 Updated config.h to use the same location for the lease
1179 file on NetBSD as the other *BSD variants. Also allow
1180 LEASEFILE and CONFFILE symbols to be overriden in CFLAGS.
1181
1182 Handle duplicate address detection on IPv6 more
1183 intelligently. In IPv6, an interface can have an address
1184 which is not usable, because it is still undergoing DAD
1185 (such addresses are marked "tentative"). Attempting to
1186 bind to an address in this state returns an error,
1187 EADDRNOTAVAIL. Previously, on getting such an error,
1188 dnsmasq would silently abandon the address, and never
1189 listen on it. Now, it retries once per second for 20
1190 seconds before generating a fatal error. 20 seconds should
1191 be long enough for any DAD process to complete, but can be
1192 adjusted in src/config.h if necessary. Thanks to Martin
1193 Krafft for the bug report.
1194
1195 Add DBus introspection. Patch from Jeremy Laine.
1196
1197 Update Dbus configuration file. Patch from Colin Walters.
1198 Fix for this bug:
1199 http://bugs.freedesktop.org/show_bug.cgi?id=18961
1200
1201 Support arbitrarily encapsulated DHCP options, suggestion
1202 and initial patch from Samium Gromoff. This is useful for
1203 (eg) gPXE, which expect all its private options to be
1204 encapsulated inside a single option 175. So, eg,
1205
1206 dhcp-option = encap:175, 190, "iscsi-client0"
1207 dhcp-option = encap:175, 191, "iscsi-client0-secret"
1208
1209 will provide iSCSI parameters to gPXE.
1210
1211 Enhance --dhcp-match to allow testing of the contents of a
1212 client-sent option, as well as its presence. This
1213 application in mind for this is RFC 4578
1214 client-architecture specifiers, but it's generally useful.
1215 Joey Korkames suggested the enhancement.
1216
1217 Move from using the IP_XMIT_IF ioctl to IP_BOUND_IF on
1218 OpenSolaris. Thanks to Bastian Machek for the heads-up.
1219
1220 No longer complain about blank lines in
1221 /etc/ethers. Thanks to Jon Nelson for the patch.
1222
1223 Fix binding of servers to physical devices, eg
1224 --server=/domain/1.2.3.4@eth0 which was broken from 2.43
1225 onwards unless --query-port=0 set. Thanks to Peter Naulls
1226 for the bug report.
1227
1228 Reply to DHCPINFORM requests even when the supplied ciaddr
1229 doesn't fall in any dhcp-range. In this case it's not
1230 possible to supply a complete configuration, but
1231 individually-configured options (eg PAC) may be useful.
1232
1233 Allow the source address of an alias to be a range:
1234 --alias=192.168.0.0,10.0.0.0,255.255.255.0 maps the whole
1235 subnet 192.168.0.0->192.168.0.255 to 10.0.0.0->10.0.0.255,
1236 as before.
1237 --alias=192.168.0.10-192.168.0.40,10.0.0.0,255.255.255.0
1238 maps only the 192.168.0.10->192.168.0.40 region. Thanks to
1239 Ib Uhrskov for the suggestion.
1240
1241 Don't dynamically allocate DHCP addresses which may break
1242 Windows. Addresses which end in .255 or .0 are broken in
1243 Windows even when using supernetting.
1244 --dhcp-range=192.168.0.1,192.168.1.254,255,255,254.0 means
1245 192.168.0.255 is a valid IP address, but not for Windows.
1246 See Microsoft KB281579. We therefore no longer allocate
1247 these addresses to avoid hard-to-diagnose problems.
1248
1249 Update Polish translation. Thanks to Jan Psota.
1250
1251 Delete the PID-file when dnsmasq shuts down. Note that by
1252 this time, dnsmasq is normally not running as root, so
1253 this will fail if the PID-file is stored in a root-owned
1254 directory; such failure is silently ignored. To take
1255 advantage of this feature, the PID-file must be stored in a
1256 directory owned and write-able by the user running
1257 dnsmasq.
1258
1259
1260 version 2.46
1261 Allow --bootp-dynamic to take a netid tag, so that it may
1262 be selectively enabled. Thanks to Olaf Westrik for the
1263 suggestion.
1264
1265 Remove ISC-leasefile reading code. This has been
1266 deprecated for a long time, and last time I removed it, it
1267 ended up going back by request of one user. This time,
1268 it's gone for good; otherwise it would need to be
1269 re-worked to support multiple domains (see below).
1270
1271 Support DHCP clients in multiple DNS domains. This is a
1272 long-standing request. Clients are assigned to a domain
1273 based in their IP address.
1274
1275 Add --dhcp-fqdn flag, which changes behaviour if DNS names
1276 assigned to DHCP clients. When this is set, there must be
1277 a domain associated with each client, and only
1278 fully-qualified domain names are added to the DNS. The
1279 advantage is that the only the FQDN needs to be unique,
1280 so that two or more DHCP clients can share a hostname, as
1281 long as they are in different domains.
1282
1283 Set environment variable DNSMASQ_DOMAIN when invoking
1284 lease-change script. This may be useful information to
1285 have now that it's variable.
1286
1287 Tighten up data-checking code for DNS packet
1288 handling. Thanks to Steve Dodd who found certain illegal
1289 packets which could crash dnsmasq. No memory overwrite was
1290 possible, so this is not a security issue beyond the DoS
1291 potential.
1292
1293 Update example config dhcp option 47, the previous
1294 suggestion generated an illegal, zero-length,
1295 option. Thanks to Matthias Andree for finding this.
1296
1297 Rewrite hosts-file reading code to remove the limit of
1298 1024 characters per line. John C Meuser found this.
1299
1300 Create a net-id tag with the name of the interface on
1301 which the DHCP request was received.
1302
1303 Fixed minor memory leak in DBus code, thanks to Jeremy
1304 Laine for the patch.
1305
1306 Emit DBus signals as the DHCP lease database
1307 changes. Thanks to Jeremy Laine for the patch.
1308
1309 Allow for more that one MAC address in a dhcp-host
1310 line. This configuration tells dnsmasq that it's OK to
1311 abandon a DHCP lease of the fixed address to one MAC
1312 address, if another MAC address in the dhcp-host statement
1313 asks for an address. This is useful to give a fixed
1314 address to a host which has two network interfaces
1315 (say, a laptop with wired and wireless interfaces.)
1316 It's very important to ensure that only one interface
1317 at a time is up, since dnsmasq abandons the first lease
1318 and re-uses the address before the leased time has
1319 elapsed. John Gray suggested this.
1320
1321 Tweak the response to a DHCP request packet with a wrong
1322 server-id when --dhcp-authoritative is set; dnsmasq now
1323 returns a DHCPNAK, rather than silently ignoring the
1324 packet. Thanks to Chris Marget for spotting this
1325 improvement.
1326
1327 Add --cname option. This provides a limited alias
1328 function, usable for DHCP names. Thanks to AJ Weber for
1329 suggestions on this.
1330
1331 Updated contrib/webmin with latest version from Neil
1332 Fisher.
1333
1334 Updated Polish translation. Thanks to Jan Psota.
1335
1336 Correct the text names for DHCP options 64 and 65 to be
1337 "nis+-domain" and "nis+-servers".
1338
1339 Updated Spanish translation. Thanks to Chris Chatham.
1340
1341 Force re-reading of /etc/resolv.conf when an "interface
1342 up" event occurs.
1343
1344
1345 version 2.45
1346 Fix total DNS failure in release 2.44 unless --min-port
1347 specified. Thanks to Steven Barth and Grant Coady for
1348 bugreport. Also reject out-of-range port spec, which could
1349 break things too: suggestion from Gilles Espinasse.
1350
1351
1352 version 2.44
1353 Fix crash when unknown client attempts to renew a DHCP
1354 lease, problem introduced in version 2.43. Thanks to
1355 Carlos Carvalho for help chasing this down.
1356
1357 Fix potential crash when a host which doesn't have a lease
1358 does DHCPINFORM. Again introduced in 2.43. This bug has
1359 never been reported in the wild.
1360
1361 Fix crash in netlink code introduced in 2.43. Thanks to
1362 Jean Wolter for finding this.
1363
1364 Change implementation of min_port to work even if min-port
1365 is large.
1366
1367 Patch to enable compilation of latest Mac OS X. Thanks to
1368 David Gilman.
1369
1370 Update Spanish translation. Thanks to Christopher Chatham.
1371
1372
1373 version 2.43
1374 Updated Polish translation. Thanks to Jan Psota.
1375
1376 Flag errors when configuration options are repeated
1377 illegally.
1378
1379 Further tweaks for GNU/kFreeBSD
1380
1381 Add --no-wrap to msgmerge call - provides nicer .po file
1382 format.
1383
1384 Honour lease-time spec in dhcp-host lines even for
1385 BOOTP. The user is assumed to known what they are doing in
1386 this case. (Hosts without the time spec still get infinite
1387 leases for BOOTP, over-riding the default in the
1388 dhcp-range.) Thanks to Peter Katzmann for uncovering this.
1389
1390 Fix problem matching relay-agent ids. Thanks to Michael
1391 Rack for the bug report.
1392
1393 Add --naptr-record option. Suggestion from Johan
1394 Bergquist.
1395
1396 Implement RFC 5107 server-id-override DHCP relay agent
1397 option.
1398
1399 Apply patches from Stefan Kruger for compilation on
1400 Solaris 10 under Sun studio.
1401
1402 Yet more tweaking of Linux capability code, to suppress
1403 pointless wingeing from kernel 2.6.25 and above.
1404
1405 Improve error checking during startup. Previously, some
1406 errors which occurred during startup would be worked
1407 around, with dnsmasq still starting up. Some were logged,
1408 some silent. Now, they all cause a fatal error and dnsmasq
1409 terminates with a non-zero exit code. The errors are those
1410 associated with changing uid and gid, setting process
1411 capabilities and writing the pidfile. Thanks to Uwe
1412 Gansert and the Suse security team for pointing out
1413 this improvement, and Bill Reimers for good implementation
1414 suggestions.
1415
1416 Provide NO_LARGEFILE compile option to switch off largefile
1417 support when compiling against versions of uclibc which
1418 don't support it. Thanks to Stephane Billiart for the patch.
1419
1420 Implement random source ports for interactions with
1421 upstream nameservers. New spoofing attacks have been found
1422 against nameservers which do not do this, though it is not
1423 clear if dnsmasq is vulnerable, since to doesn't implement
1424 recursion. By default dnsmasq will now use a different
1425 source port (and socket) for each query it sends
1426 upstream. This behaviour can suppressed using the
1427 --query-port option, and the old default behaviour
1428 restored using --query-port=0. Explicit source-port
1429 specifications in --server configs are still honoured.
1430
1431 Replace the random number generator, for better
1432 security. On most BSD systems, dnsmasq uses the
1433 arc4random() RNG, which is secure, but on other platforms,
1434 it relied on the C-library RNG, which may be
1435 guessable and therefore allow spoofing. This release
1436 replaces the libc RNG with the SURF RNG, from Daniel
1437 J. Berstein's DJBDNS package.
1438
1439 Don't attempt to change user or group or set capabilities
1440 if dnsmasq is run as a non-root user. Without this, the
1441 change from soft to hard errors when these fail causes
1442 problems for non-root daemons listening on high
1443 ports. Thanks to Patrick McLean for spotting this.
1444
1445 Updated French translation. Thanks to Gildas Le Nadan.
1446
1447
1448 version 2.42
1449 The changelog for version 2.42 and earlier is
1450 available in CHANGELOG.archive.
