Simon Kelley333b2ce2013-01-07 21:46:03 +00001version 2.66
2 Add the ability to act as an authoritative DNS
3 server. Dnsmasq can now answer queries from the wider 'net
4 with local data, as long as the correct NS records are set
5 up. Only local data is provided, to avoid creating an open
6 DNS relay. Zone transfer is supported, to allow secondary
7 servers to be configured.
8
9 Add "constructed DHCP ranges" for DHCPv6. This is intended
10 for IPv6 routers which get prefixes dynamically via prefix
11 delegation. With suitable configuration, stateful DHCPv6
12 and RA can happen automatically as prefixes are delegated
13 and then deprecated, without having to re-write the
14 dnsmasq configuration file or restart the daemon. Thanks to
15 Steven Barth for extensive testing and development work on
16 this idea.

18 Fix crash on startup on Solaris 11. Regression probably
Simon Kelley22ce5502013-01-22 13:53:04 +000019 introduced in 2.61. Thanks to Geoff Johnstone for the
20 patch.
21
22 Add code to make behaviour for TCP DNS requests that same
23 as for UDP requests, when a request arrives for an allowed
24 address, but via a banned interface. This change is only
25 active on Linux, since the relevant API is missing (AFAIK)
26 on other platforms. Many thanks to Tomas Hozza for
27 spotting the problem, and doing invaluable discovery of
28 the obscure and undocumented API required for the solution.
Simon Kelleya21e27b2013-02-17 16:41:35 +000029
30 Don't send the default DHCP option advertising dnsmasq as
31 the local DNS server if dnsmasq is configured to not act
32 as DNS server, or it's configured to a non-standard port.
Simon Kelleydd1721c2013-02-18 21:04:04 +000033
34 Add DNSMASQ_CIRCUIT_ID, DNSMASQ_SUBCRIBER_ID,
35 DNSMASQ_REMOTE_ID variables to the environment of the
36 lease-change script (and the correponding Lua). These hold
37 information inserted into the DHCP request by a DHCP relay
38 agent. Thanks to Lakefield Communications for providing a
39 bounty for this addition.
40
Simon Kelley4038ae22013-02-19 16:47:07 +000041 Fixed crash, introduced in 2.64, whilst handling DHCPv6
42 information-requests with some common configurations.
43 Thanks to Robert M. Albrecht for the bug report and
44 chasing the problem.
45
Simon Kelley333b2ce2013-01-07 21:46:03 +000046
Simon Kelleyee86ce62012-12-07 11:54:46 +000047version 2.65
48 Fix regression which broke forwarding of queries sent via
49 TCP which are not for A and AAAA and which were directed to
50 non-default servers. Thanks to Niax for the bug report.
51
Simon Kelleyb5a8dd12012-12-10 11:37:25 +000052 Fix failure to build with DHCP support excluded. Thanks to
53 Gustavo Zacarias for the patch.
Simon Kelley1d6c6392012-12-14 11:19:36 +000054
55 Fix nasty regression in 2.64 which completely broke cacheing.
Simon Kelleyb5a8dd12012-12-10 11:37:25 +000056
57
Simon Kelley2e34ac12012-08-29 14:15:25 +010058version 2.64
59 Handle DHCP FQDN options with all flag bits zero and
60 --dhcp-client-update set. Thanks to Bernd Krumbroeck for
61 spotting the problem.
62
Simon Kelley12d71ed2012-08-30 15:16:41 +010063 Finesse the check for /etc/hosts names which conflict with
64 DHCP names. Previously a name/address pair in /etc/hosts
65 which didn't match the name/address of a DHCP lease would
66 generate a warning. Now that only happesn if there is not
67 also a match. This allows multiple addresses for a name in
68 /etc/hosts with one of them assigned via DHCP.
69
Simon Kelley4d0f5b42012-09-05 23:29:30 +010070 Fix broken vendor-option processing for BOOTP. Thanks to
71 Hans-Joachim Baader for the bug report.
72
Simon Kelleydfb23b32012-09-18 21:44:47 +010073 Don't report spurious netlink errors, regression in
74 2.63. Thanks to Vladislav Grishenko for the patch.
75
Simon Kelley2b127a12012-09-18 21:51:22 +010076 Flag DHCP or DHCPv6 in starup logging. Thanks to
77 Vladislav Grishenko for the patch.
78
Simon Kelley295a54e2012-12-01 21:02:15 +000079 Add SetServersEx method in DBus interface. Thanks to Dan
Simon Kelleyfaafb3f2012-09-20 14:17:39 +010080 Williams for the patch.
81
Simon Kelley295a54e2012-12-01 21:02:15 +000082 Add SetDomainServers method in DBus interface. Thanks to
83 Roy Marples for the patch.
84
Simon Kelley289a2532012-09-20 15:29:35 +010085 Fix build with later Lua libraries. Thansk to Cristian
86 Rodriguez for the patch.
Simon Kelley2e34ac12012-08-29 14:15:25 +010087
Simon Kelley1d860412012-09-20 20:48:04 +010088 Add --max-cache-ttl option. Thanks to Dennis Kaarsemaker
89 for the patch.
90
Simon Kelleye4807d82012-09-27 21:52:26 +010091 Fix breakage of --host-record parsing, resulting in
92 infinte loop at startup. Regression in 2.63. Thanks to
93 Haim Gelfenbeyn for spotting this.
94
Simon Kelley20223102012-10-15 10:41:17 +010095 Set SO_REUSEADDRESS and SO_V6ONLY options on the DHCPv6
96 socket, this allows multiple instances of dnsmasq on a
97 single machine, in the same way as for DHCPv4. Thanks to
98 Gene Czarcinski and Vladislav Grishenko for work on this.
99
Simon Kelleybe6cfb42012-10-16 20:38:31 +0100100 Fix DHCPv6 to do access control correctly when it's
101 configured with --listen-address. Thanks to
102 Gene Czarcinski for sorting this out.
103
Simon Kelley819ff4d2012-10-21 18:25:12 +0100104 Add a "wildcard" dhcp-range which works for any IPv6
105 subnet, --dhcp-range=::,static Useful for Stateless
106 DHCPv6. Thanks to Vladislav Grishenko for the patch.
107
Simon Kelleyd1a59752012-11-05 16:50:30 +0000108 Don't include lease-time in DHCPACK replies to DHCPINFORM
109 queries, since RFC-2131 says we shouldn't. Thanks to
110 Wouter Ibens for pointing this out.
Simon Kelley8e4b8792012-11-14 14:12:56 +0000111
112 Makefile tweak to do dependency checking on header files.
113 Thanks to Johan Peeters for the patch.
Simon Kelleyd89fb4e2012-12-01 21:21:13 +0000114
115 Check interface for outgoing unsolicited router
116 advertisements, rather than relying on interface address
117 configuration. Thanks to Gene Czarinski for the patch.
Simon Kelley29d28dd2012-12-03 14:05:59 +0000118
119 Handle better attempts to transmit on interfaces which are
120 still doing DAD, and specifically do not just transmit
121 without setting source address and interface, since this
122 can cause very puzzling effects when a router
123 advertisement goes astray. Thanks again to Gene Czarinski.
124
125 Get RA timers right when there is more than one
126 dhcp-range on a subnet.
Simon Kelley289a2532012-09-20 15:29:35 +0100127
Simon Kelleyd1a59752012-11-05 16:50:30 +0000128
Simon Kelley078a6302012-06-07 13:56:23 +0100129version 2.63
130 Do duplicate dhcp-host address check in --test mode.
131
Simon Kelley8b3ae2f2012-06-13 13:43:49 +0100132 Check that tftp-root directories are accessible before
133 start-up. Thanks to Daniel Veillard for the initial patch.
134
135 Allow more than one --tfp-root flag. The per-interface
136 stuff is pointless without that.
137
Simon Kelley54dd3932012-06-20 11:23:38 +0100138 Add --bind-dynamic. A hybrid mode between the default and
139 --bind-interfaces which copes with dynamically created
140 interfaces.
Simon Kelley6b617c02012-06-29 21:15:42 +0100141
142 A couple of fixes to the build system for Android. Thanks
143 to Metin Kaya for the patches.
Simon Kelley54dd3932012-06-20 11:23:38 +0100144
Simon Kelley8bc4cec2012-07-03 21:04:11 +0100145 Remove the interface:<interface> argument in --dhcp-range, and
146 the interface argument to --enable-tftp. These were a
147 still-born attempt to allow automatic isolated
148 configuration by libvirt, but have never (to my knowledge)
149 been used, had very strange semantics, and have been
150 superceded by other mechanisms.
151
Simon Kelleyc4a7f902012-07-12 20:52:12 +0100152 Fixed bug logging filenames when duplicate dhcp-host
153 addresses are found. Thanks to John Hanks for the patch.
154
Simon Kelley611ebc52012-07-16 16:23:46 +0100155 Fix regression in 2.61 which broke caching of CNAME
156 chains. Thanks to Atul Gupta for the bug report.
157
Simon Kelleyb2714462012-07-17 12:09:26 +0100158 Allow the target of a --cname flag to be another --cname.
Simon Kelley611ebc52012-07-16 16:23:46 +0100159
Simon Kelley42243212012-07-20 15:19:18 +0100160 Teach DHCPv6 about the RFC 4242 information-refresh-time
161 option, and add parsing if the minutes, hours and days
162 format for options. Thanks to Francois-Xavier Le Bail for
163 the suggestion.
164
165 Allow "w" (for week) as multiplier in lease times, as well
166 as seconds, minutes, hours and days. Álvaro Gámez Machado
167 spotted the ommission.
Simon Kelleyc4c04882012-08-06 20:09:15 +0100168
169 Update French translation. Thanks to Gildas Le Nadan.
Simon Kelley42243212012-07-20 15:19:18 +0100170
Simon Kelleyad094272012-08-10 17:10:54 +0100171 Allow a DBus service name to be given with --enable-dbus
172 which overrides the default,
173 uk.org.thekelleys.dnsmasq. Thanks to Mathieu
174 Trudel-Lapierre for the patch.
175
Simon Kelleyfd05f122012-08-12 17:48:50 +0100176 Set the "prefix on-link" bit in Router
177 Advertisements. Thanks to Gui Iribarren for the patch.
178
Simon Kelley078a6302012-06-07 13:56:23 +0100179
Simon Kelley8358e0f2012-04-29 21:53:09 +0100180version 2.62
181 Update German translation. Thanks to Conrad Kostecki.
182
Simon Kelleyf632e562012-05-12 15:05:34 +0100183 Cope with router-solict packets wich don't have a valid
184 source address. Thanks to Vladislav Grishenko for the patch.
185
Simon Kelley919dd7c2012-05-12 15:23:09 +0100186 Fixed bug which caused missing periodic router
187 advertisements with some configurations. Thanks to
188 Vladislav Grishenko for the patch.
189
Simon Kelleyc64b7f62012-05-18 10:19:59 +0100190 Fixed bug which broke DHCPv6/RA with prefix lengths
191 which are not divisible by 8. Thanks to Andre Coetzee
192 for spotting this.
193
Simon Kelley18c63ef2012-05-21 14:34:15 +0100194 Fix non-response to router-solicitations when
195 router-advertisement configured, but DHCPv6 not
196 configured. Thanks to Marien Zwart for the patch.
197
Simon Kelley9f7f3b12012-05-28 21:39:57 +0100198 Add --dns-rr, to allow arbitrary DNS resource records.
199
Simon Kelley5ae34bf2012-06-04 21:14:03 +0100200 Fixed bug which broke RA scheduling when an interface had
201 two addresses in the same network. Thanks to Jim Bos for
202 his help nailing this.
203
Simon Kelleyeabc6dd2012-03-07 20:28:20 +0000204version 2.61
205 Re-write interface discovery code on *BSD to use
206 getifaddrs. This is more portable, more straightforward,
207 and allows us to find the prefix length for IPv6
208 addresses.
209
Simon Kelley01d1b8d2012-03-28 21:37:25 +0100210 Add ra-names, ra-stateless and slaac keywords for DHCPv6.
211 Dnsmasq can now synthesise AAAA records for dual-stack
212 hosts which get IPv6 addresses via SLAAC. It is also now
213 possible to use SLAAC and stateless DHCPv6, and to
214 tell clients to use SLAAC addresses as well as DHCP ones.
215 Thanks to Dave Taht for help with this.
Simon Kelley7023e382012-03-09 12:05:49 +0000216
Simon Kelley8b372702012-03-09 17:45:10 +0000217 Add --dhcp-duid to allow DUID-EN uids to be used.
218
Simon Kelley8643ec72012-03-12 20:04:14 +0000219 Explicity send DHCPv6 replies to the correct port, instead
220 of relying on clients to send requests with the correct
221 source address, since at least one client in the wild gets
Simon Kelley8358e0f2012-04-29 21:53:09 +0100222 this wrong. Thanks to Conrad Kostecki for help tracking
Simon Kelley8643ec72012-03-12 20:04:14 +0000223 this down.
Simon Kelleyeabc6dd2012-03-07 20:28:20 +0000224
Simon Kelley8643ec72012-03-12 20:04:14 +0000225 Send a preference value of 255 in DHCPv6 replies when
226 --dhcp-authoritative is in effect. This tells clients not
227 to wait around for other DHCP servers.
228
229 Better logging of DHCPv6 options.
230
Simon Kelleye759d422012-03-16 13:18:57 +0000231 Add --host-record. Thanks to Rob Zwissler for the
232 suggestion.
233
Simon Kelleya9530962012-03-20 22:07:35 +0000234 Invoke the DHCP script with action "tftp" when a TFTP file
235 transfer completes. The size of the file, address to which
236 it was sent and complete pathname are supplied. Note that
237 version 2.60 introduced some script incompatibilties
238 associated with DHCPv6, and this is a further change. To
239 be safe, scripts should ignore unknown actions, and if
240 not IPv6-aware, should exit if the environment
241 variable DNSMASQ_IAID is set. The use-case for this is
242 to track netboot/install. Suggestion from Shantanu
243 Gadgil.
244
245 Update contrib/port-forward/dnsmasq-portforward to reflect
246 the above.
247
248 Set the environment variable DNSMASQ_LOG_DHCP when running
249 the script id --log-dhcp is in effect, so that script can
Simon Kelley52d4abf2012-03-21 21:39:48 +0000250 taylor their logging verbosity. Suggestion from Malte
251 Forkel.
252
253 Arrange that addresses specified with --listen-address
254 work even if there is no interface carrying the
255 address. This is chiefly useful for IPv4 loopback
256 addresses, where any address in 127.0.0.0/8 is a valid
257 loopback address, but normally only 127.0.0.1 appears on
258 the lo interface. Thanks to Mathieu Trudel-Lapierre for
259 the idea and initial patch.
Simon Kelleya9530962012-03-20 22:07:35 +0000260
Simon Kelley7d2b5c92012-03-23 10:00:02 +0000261 Fix crash, introduced in 2.60, when a DHCPINFORM is
262 received from a network which has no valid dhcp-range.
263 Thanks to Stephane Glondu for the bug report.
264
Simon Kelleyc8257542012-03-28 21:15:41 +0100265 Add a new DHCP lease time keyword, "deprecated" for
266 --dhcp-range. This is only valid for IPv6, and sets the
267 preffered lease time for both DHCP and RA to zero. The
268 effect is that clients can continue to use the address
269 for existing connections, but new connections will use
270 other addresses, if they exist. This makes hitless
271 renumbering at least possible.
272
273 Fix bug in address6_available() which caused DHCPv6 lease
Simon Kelley8358e0f2012-04-29 21:53:09 +0100274 aquisition to fail if more than one dhcp-range in use.
Simon Kelley18f0fb02012-03-31 21:18:55 +0100275
276 Provide RDNSS and DNSSL data in router advertisements,
277 using the settings provided for DHCP options
278 option6:domain-search and option6:dns-server.
Simon Kelley6c559c32012-04-02 20:40:34 +0100279

Simon Kelley1023dcb2012-04-09 18:00:08 +0100283 Don't cache data from non-recursive nameservers, since it
284 may erroneously look like a valid CNAME to a non-exitant
285 name. Thanks to Ben Winslow for finding this.
Simon Kelley9380ba72012-04-16 14:41:56 +0100286
287 Call SO_BINDTODEVICE on the DHCP socket(s) when doing DHCP
Simon Kelley8358e0f2012-04-29 21:53:09 +0100288 on exactly one interface and --bind-interfaces is set. This
Simon Kelley9380ba72012-04-16 14:41:56 +0100289 makes the OpenStack use-case of one dnsmasq per virtual
290 interface work. This is only available on Linux; it's not
291 supported on other platforms. Thanks to Vishvananda Ishaya
Simon Kelleye46164e2012-04-16 16:39:38 +0100292 and the OpenStack team for the suggestion.
293
294 Updated French translation. Thanks to Gildas Le Nadan.
Simon Kelleyd1c759c2012-04-16 17:26:19 +0100295

302 Ensure that the DBus DhcpLeaseUpdated events are generated
303 when a lease goes through INIT_REBOOT state, even if the
Simon Kelley8358e0f2012-04-29 21:53:09 +0100304 dhcp-script is not in use. Thanks to Antoaneta-Ecaterina

312 Fix compilation problem in Mac OS X Lion. Thanks to Olaf
313 Flebbe for the patch.
Simon Kelley74c95c22011-10-19 09:33:39 +0100314
Simon Kelleyc72daea2012-01-05 21:33:27 +0000315 Fix DHCP when using --listen-address with an IP address
316 which is not the primary address of an interface.
317
318 Add --dhcp-client-update option.
319
320 Add Lua integration. Dnsmasq can now execute a DHCP
321 lease-change script written in Lua. This needs to be
322 enabled at compile time by setting HAVE_LUASCRIPT in
323 src/config.h or running "make COPTS=-DHAVE_LUASCRIPT"
324 Thanks to Jan-Piet Mens for the idea and proof-of-concept
325 implementation.
326
327 Tidied src/config.h to distinguish between
328 platform-dependent compile-time options which are selected
329 automatically, and builder-selectable compile time
330 options. Document the latter better, and describe how to
331 set them from the make command line.
332
333 Tidied up IPPROTO_IP/SOL_IP (and IPv6 equivalent)
334 confusion. IPPROTO_IP works everywhere now.
335
336 Set TOS on DHCP sockets, this improves things on busy
337 wireless networks. Thanks to Dave Taht for the patch.
338
Simon Kelley984d2fd2012-01-06 14:34:32 +0000339 Determine VERSION automatically based on git magic:
340 release tags or hash values.
Simon Kelleyc72daea2012-01-05 21:33:27 +0000341
Simon Kelleya2761752012-01-18 16:07:21 +0000342 Improve start-up speed when reading large hosts files
343 containing many distinct addresses.
344
345 Fix problem if dnsmasq is started without the stdin,
346 stdout and stderr file descriptors open. This can manifest
347 itself as 100% CPU use. Thanks to Chris Moore for finding
348 this.
349
Simon Kelley9bbc8872012-02-09 21:33:09 +0000350 Fix shell-scripting bug in bld/pkg-wrapper. Thanks to
351 Mark Mitchell for the patch.
352
Simon Kelley751d6f42012-02-10 15:24:51 +0000353 Allow the TFP server or boot server in --pxe-service, to
354 be a domain name instead of an IP address. This allows for
355 round-robin to multiple servers, in the same way as
356 --dhcp-boot. A good suggestion from Cristiano Cumer.
357
Simon Kelleyfdacfb02012-02-28 15:20:25 +0000358 Support BUILDDIR variable in the Makefile. Allows builds
359 for multiple archs from the same source tree with eg.
360 make BUILDDIR=linux (relative to dnsmasq tree)
361 make BUILDDIR=/tmp/openbsd (absolute path)

Simon Kelleyb36ae192012-02-13 12:54:34 +0000363 directory, as before. Suggestion from Mark Mitchell.
364
Simon Kelleyfdacfb02012-02-28 15:20:25 +0000365 Support DHCPv6. Support is there for the sort of things
366 the existing v4 server does, including tags, options,
367 static addresses and relay support. Missing is prefix
368 delegation, which is probably not required in the dnsmasq
369 niche, and an easy way to accept prefix delegations from
370 an upstream DHCPv6 server, which is. Future plans include
371 support for DHCPv6 router option and MAC address option
372 (to make selecting clients by MAC address work like IPv4).
373 These will be added as the standards mature.
374 This code has been tested, but this is the first release,
375 so don't bet the farm on it just yet. Many thanks to all
376 testers who have got it this far.
Simon Kelley1adadf52012-02-13 22:15:58 +0000377
Simon Kelleyac8540c2012-02-26 20:57:31 +0000378 Support IPv6 router advertisements. This is a
379 simple-minded implementation, aimed at providing the
380 vestigial RA needed to go alongside IPv6. Is picks up
381 configuration from the DHCPv6 conf, and should just need
382 enabling with --enable-ra.
383
Simon Kelley552af8b2012-02-29 20:10:31 +0000384 Fix long-standing wrinkle with --localise-queries that
385 could result in wrong answers when DNS packets arrive
386 via an interface other than the expected one. Thanks to
387 Lorenzo Milesi and John Hanks for spotting this one.
Simon Kelley71ee7ee2012-03-03 18:06:49 +0000388
389 Update French translation. Thanks to Gildas Le Nadan.

393
Simon Kelleyc72daea2012-01-05 21:33:27 +0000394version 2.59
395 Fix regression in 2.58 which caused failure to start up
396 with some combinations of dnsmasq config and IPv6 kernel
397 network config. Thanks to Brielle Bruns for the bug
398 report.
399
400 Improve dnsmasq's behaviour when network interfaces are
401 still doing duplicate address detection (DAD). Previously,
402 dnsmasq would wait up to 20 seconds at start-up for the
403 DAD state to terminate. This is broken for bridge
404 interfaces on recent Linux kernels, which don't start DAD
405 until the bridge comes up, and so can take arbitrary
406 time. The new behaviour lets dnsmasq poll for an arbitrary
407 time whilst providing service on other interfaces. Thanks
408 to Stephen Hemminger for pointing out the problem.
Simon Kelley74c95c22011-10-19 09:33:39 +0100409
410
Simon Kelley7de060b2011-08-26 17:24:52 +0100411version 2.58
412 Provide a definition of the SA_SIZE macro where it's
413 missing. Fixes build failure on openBSD.
414
415 Don't include a zero terminator at the end of messages
416 sent to /dev/log when /dev/log is a datagram socket.
417 Thanks to Didier Rabound for spotting the problem.
418
419 Add --dhcp-sequential-ip flag, to force allocation of IP
420 addresses in ascending order. Note that the default
421 pseudo-random mode is in general better but some
422 server-deployment applications need this.
423
424 Fix problem where a server-id of 0.0.0.0 is sent to a
425 client when a dhcp-relay is in use if a client renews a
426 lease after dnsmasq restart and before any clients on the
427 subnet get a new lease. Thanks to Mike Ruiz for assistance
428 in chasing this one down.
429
430 Don't return NXDOMAIN to an AAAA query if we have CNAME
431 which points to an A record only: NODATA is the correct
432 reply in this case. Thanks to Tom Fernandes for spotting
433 the problem.
434
435 Relax the need to supply a netmask in --dhcp-range for
436 networks which use a DHCP relay. Whilst this is still
437 desireable, in the absence of a netmask dnsmasq will use
438 a default based on the class (A, B, or C) of the address.
439 This should at least remove a cause of mysterious failure
440 for people using RFC1918 addresses and relays.
441
442 Add support for Linux conntrack connection marking. If
443 enabled with --conntrack, the connection mark for incoming
444 DNS queries will be copied to the outgoing connections
445 used to answer those queries. This allows clever firewall
446 and accounting stuff. Only available if dnsmasq is
447 compiled with HAVE_CONNTRACK and adds a dependency on
448 libnetfilter-conntrack. Thanks to Ed Wildgoose for the
449 initial idea, testing and sponsorship of this function.
450
451 Provide a sane error message when someone attempts to
452 match a tag in --dhcp-host.
453
454 Tweak the behaviour of --domain-needed, to avoid problems
455 with recursive nameservers downstream of dnsmasq. The new
456 behaviour only stops A and AAAA queries, and returns
457 NODATA rather than NXDOMAIN replies.
458
459 Efficiency fix for very large DHCP configurations, thanks
460 to James Gartrell and Mike Ruiz for help with this.
461
462 Allow the TFTP-server address in --dhcp-boot to be a
463 domain-name which is looked up in /etc/hosts. This can
464 give multiple IP addresses which are used round-robin,
465 thus doing TFTP server load-balancing. Thanks to Sushil
466 Agrawal for the patch.
467
468 When two tagged dhcp-options for a particular option
469 number are both valid, use the one which is valid without
470 a tag from the dhcp-range. Allows overriding of the value
471 of a DHCP option for a particular host as well as
472 per-network values. So
473 --dhcp-range=set:interface1,......
474 --dhcp-host=set:myhost,.....
475 --dhcp-option=tag:interface1,option:nis-domain,"domain1"
476 --dhcp-option=tag:myhost,option:nis-domain,"domain2"
477 will set the NIS-domain to domain1 for hosts in the range, but
478 override that to domain2 for a particular host.
479
480 Fix bug which resulted in truncated files and timeouts for
481 some TFTP transfers. The bug only occurs with netascii
482 transfers and needs an unfortunate relationship between
483 file size, blocksize and the number of newlines in the
484 last block before it manifests itself. Many thanks to
485 Alkis Georgopoulos for spotting the problem and providing
486 a comprehensive test-case.
487
488 Fix regression in TFTP server on *BSD platforms introduced
489 in version 2.56, due to confusion with sockaddr
Simon Kelleyde604c12012-10-19 09:50:01 +0100490 length. Many thanks to Loic Pefferkorn for finding this.
Simon Kelley7de060b2011-08-26 17:24:52 +0100491
492 Support scope-ids in IPv6 addresses of nameservers from
493 /etc/resolv.conf and in --server options. Eg
494 nameserver fe80::202:a412:4512:7bbf%eth0 or
495 server=fe80::202:a412:4512:7bbf%eth0. Thanks to
496 Michael Stapelberg for the suggestion.
497
498 Update Polish translation, thanks to Jan Psota.
499
500 Update French translation. Thanks to Gildas Le Nadan.
501
502
Simon Kelley572b41e2011-02-18 18:11:18 +0000503version 2.57
504 Add patches to allow build under Android.
505
506 Provide our own header for the DNS protocol, rather than
507 relying on arpa/nameser.h. This has proved more or less
508 defective over the years and the final straw is that it's
509 effectively empty on Android.
510
511 Fix regression in 2.56 which caused hex constants in
512 configuration to be rejected if they contain the '*'
513 wildcard.
514
515 Correct wrong casts of arguments to ctype.h functions,
516 isdigit(), isxdigit() etc. Thanks to Matthias Andree for
517 spotting this.
518
519 Allow build with IDN support independently from i18n.
520 IDN support continues to be included automatically
521 when i18n is included.
522 'make COPTS=-DHAVE_IDN' is the magic incantation.
523
524 Modify check on extraneous command line junk (added in
525 2.56) so that it doesn't complain about extra _empty_
526 arguments. Otherwise this breaks libvirt.
527
528
Simon Kelley28866e92011-02-14 20:19:14 +0000529version 2.56
530 Add a patch to allow dnsmasq to get interface names right in a
531 Solaris zone. Thanks to Dj Padzensky for this.
532
533 Improve data-type parsing heuristics so that
534 --dhcp-option=option:domain-search,.
535 treats the value as a string and not an IP address.
536 Thanks to Clemens Fischer for spotting that.
537
538 Add IPv6 support to the TFTP server. Many thanks to Jan
539 'RedBully' Seiffert for the patches.
540
541 Log DNS queries at level LOG_INFO, rather then
542 LOG_DEBUG. This makes things consistent with DHCP
543 logging. Thanks to Adam Pribyl for spotting the problem.
544
545 Ensure that dnsmasq terminates cleanly when using
546 --syslog-async even if it cannot make a connection to the
547 syslogd.
548
549 Add --add-mac option. This is to support currently
550 experimental DNS filtering facilities. Thanks to Benjamin
551 Petrin for the orignal patch.
552
553 Fix bug which meant that tags were ignored in dhcp-range
554 configuration specifying PXE-proxy service. Thanks to
555 Cristiano Cumer for spotting this.
556
557 Raise an error if there is extra junk, not part of an
558 option, on the command line.
559
560 Flag a couple of log messages in cache.c as coming from
561 the DHCP subsystem. Thanks to Olaf Westrik for the patch.
562
563 Omit timestamps from logs when a) logging to stderr and
564 b) --keep-in-forground is set. The logging facility on the
565 other end of stderr can be assumned to supply them. Thanks
566 to John Hallam for the patch.
567
568 Don't complain about strings longer than 255 characters in
569 --txt-record, just split the long strings into 255
570 character chunks instead.
571
572 Fix crash on double-free. This bug can only happen when
573 dhcp-script is in use and then only in rare circumstances
574 triggered by high DHCP transaction rate and a slow
575 script. Thanks to Ferenc Wagner for finding the problem.
576
577 Only log that a file has been sent by TFTP after the
578 transfer has completed succesfully.
579
580 A good suggestion from Ferenc Wagner: extend
581 the --domain option to allow this sort of thing:
582 --domain=thekelleys.org.uk,192.168.0.0/24,local
583 which automatically creates
584 --local=/thekelleys.org.uk/
585 --local=/0.168.192.in-addr.arpa/
586
587 Tighten up syntax checking of hex contants in the config
588 file. Thanks to Fred Damen for spotting this.
589
590 Add dnsmasq logo/icon, contributed by Justin Swift. Many
591 thanks for that.
592
593 Never cache DNS replies which have the 'cd' bit set, or
594 which result from queries forwarded with the 'cd' bit
595 set. The 'cd' bit instructs a DNSSEC validating server
596 upstream to ignore signature failures and return replies
597 anyway. Without this change it's possible to pollute the
598 dnsmasq cache with bad data by making a query with the
599 'cd' bit set and subsequent queries would return this data
600 without its being marked as suspect. Thanks to Anders
601 Kaseorg for pointing out this problem.
602
603 Add --proxy-dnssec flag, for compliance with RFC
604 4035. Dnsmasq will now clear the 'ad' bit in answers returned
605 from upstream validating nameservers unless this option is
606 set.
607
608 Allow a filename of "-" for --conf-file to read
609 stdin. Suggestion from Timothy Redaelli.
610
611 Rotate the order of SRV records in replies, to provide
612 round-robin load balancing when all the priorities are
613 equal. Thanks to Peter McKinney for the suggestion.
614
615 Edit
616 contrib/MacOSX-launchd/uk.org.thekelleys.dnsmasq.plist
617 so that it doesn't log all queries to a file by
618 default. Thanks again to Peter McKinney.
619
620 By default, setting an IPv4 address for a domain but not
621 an IPv6 address causes dnsmasq to return
622 an NODATA reply for IPv6 (or vice-versa). So
623 --address=/google.com/1.2.3.4 stops IPv6 queries for
624 *google.com from being forwarded. Make it possible to
625 override this behaviour by defining the sematics if the
626 same domain appears in both --server and --address.
627 In that case, the --address has priority for the address
628 family in which is appears, but the --server has priority
629 of the address family which doesn't appear in --adddress
630 So:
631 --address=/google.com/1.2.3.4
632 --server=/google.com/#
633 will return 1.2.3.4 for IPv4 queries for *.google.com but
634 forward IPv6 queries to the normal upstream nameserver.
635 Similarly when setting an IPv6 address
636 only this will allow forwarding of IPv4 queries. Thanks to
637 William for pointing out the need for this.
638
639 Allow more than one --dhcp-optsfile and --dhcp-hostsfile
640 and make them understand directories as arguments in the
641 same way as --addn-hosts. Suggestion from John Hanks.
642
643 Ignore rebinding requests for leases we don't know
644 about. Rebind is broadcast, so we might get to overhear a
645 request meant for another DHCP server. NAKing this is
646 wrong. Thanks to Brad D'Hondt for assistance with this.
647
Simon Kelley572b41e2011-02-18 18:11:18 +0000648 Fix cosmetic bug which produced strange output when

670 Fix failure to compile on Debian/kFreeBSD. Thanks to
671 Axel Beckert and Petr Salinger.
672
673 Fix code to avoid scary strict-aliasing warnings
674 generated by gcc 4.4.
675
676 Added FAQ entry warning about DHCP failures with Vista
677 when firewalls block 255.255.255.255.
678
679 Fixed bug which caused bad things to happen if a
680 resolv.conf file which exists is subsequently removed.
681 Thanks to Nikolai Saoukh for the patch.
682
683 Rationalised the DHCP tag system. Every configuration item
684 which can set a tag does so by adding "set:<tag>" and
685 every configuration item which is conditional on a tag is
686 made so by "tag:<tag>". The NOT operator changes to '!',
687 which is a bit more intuitive too. Dhcp-host directives
688 can set more than one tag now. The old '#' NOT,
689 "net:" prefix and no-prefixes are still honoured, so
690 no existing config file needs to be changed, but
691 the documentation and new-style config files should be
692 much less confusing.
693
694 Added --tag-if to allow boolean operations on tags.
695 This allows complicated logic to be clearer and more
696 general. A great suggestion from Richard Voigt.
697
698 Add broadcast/unicast information to DHCP logging.
699
700 Allow --dhcp-broadcast to be unconditional.
701
702 Fixed incorrect behaviour with NOT <tag> conditionals in
703 dhcp-options. Thanks to Max Turkewitz for assistance
704 finding this.
705
706 If we send vendor-class encapsulated options based on the
707 vendor-class supplied by the client, and no explicit
708 vendor-class option is given, echo back the vendor-class
709 from the client.
710
711 Fix bug which stopped dnsmasq from matching both a
712 circuitid and a remoteid. Thanks to Ignacio Bravo for
713 finding this.
714
715 Add --dhcp-proxy, which makes it possible to configure
716 dnsmasq to use a DHCP relay agent as a full proxy, with
717 all DHCP messages passing through the proxy. This is
718 useful if the relay adds extra information to the packets
719 it forwards, but cannot be configured with the RFC 5107
720 server-override option.
721
722 Added interface:<iface name> part to dhcp-range. The
723 semantics of this are very odd at first sight, but it
724 allows a single line of the form
725 dhcp-range=interface:virt0,192.168.0.4,192.168.0.200
726 to be added to dnsmasq configuration which then supplies
727 DHCP and DNS services to that interface, without affecting
728 what services are supplied to other interfaces and
729 irrespective of the existance or lack of
730 interface=<interface>
731 lines elsewhere in the dnsmasq configuration. The idea is
732 that such a line can be added automatically by libvirt
733 or equivalent systems, without disturbing any manual
734 configuration.
735
736 Similarly to the above, allow --enable-tftp=<interface>
737
738 Allow a TFTP root to be set separately for requests via
739 different interfaces, --tftp-root=<path>,<interface>
740
741 Correctly handle and log clashes between CNAMES and
742 DNS names being given to DHCP leases. This fixes a bug
743 which caused nonsense IP addresses to be logged. Thanks to
744 Sergei Zhirikov for finding and analysing the problem.
745
746 Tweak flush_log so as to avoid leaving the log
747 file in non-blocking mode. O_NONBLOCK is a property of the
748 file, not the process/descriptor.
749
750 Fix contrib/Solaris10/create_package
751 (/usr/man -> /usr/share/man) Thanks to Vita Batrla.
752
753 Fix a problem where, if a client got a lease, then went
754 to another subnet and got another lease, then moved back,
755 it couldn't resume the old lease, but would instead get
756 a new address. Thanks to Leonardo Rodrigues for spotting
757 this and testing the fix.
758
759 Fix weird bug which sometimes omitted certain characters
760 from the start of quoted strings in dhcp-options. Thanks
761 to Dayton Turner for spotting the problem.
762
763 Add facility to redirect some domains to the standard
764 upstream servers: this allows something like
765 --server=/google.com/1.2.3.4 --server=/www.google.com/#
766 which will send queries for *.google.com to 1.2.3.4,
767 except *www.google.com which will be forwarded as usual.
768 Thanks to AJ Weber for prompting this addition.
769
770 Improve the hash-algorithm used to generate IP addresses
771 from MAC addresses during initial DHCP address
772 allocation. This improves performance when large numbers
773 of hosts with similar MAC addresses all try and get an IP
774 address at the same time. Thanks to Paul Smith for his
775 work on this.
776
777 Tweak DHCP code so that --bridge-interface can be used to
778 select which IP alias of an interface should be used for
779 DHCP purposes on Linux. If eth0 has an alias eth0:dhcp
780 then adding --bridge-interface=eth0:dhcp,eth0 will use
781 the address of eth0:dhcp to determine the correct subnet
782 for DHCP address allocation. Thanks to Pawel Golaszewski
783 for prompting this and Eric Cooper for further testing.
784
785 Add --dhcp-generate-names. Suggestion by Ferenc Wagner.
786
787 Tweak DNS server selection algorithm when there is more
788 than one server available for a domain, eg.
789 --server=/mydomain/1.1.1.1
790 --server=/mydomain/2.2.2.2
791 Thanks to Alberto Cuesta-Canada for spotting a weakness
792 here.
793
794 Add --max-ttl. Thanks to Fredrik Ringertz for the patch.
795
796 Allow --log-facility=- to force all logging to
797 stderr. Suggestion from Clemens Fischer.
798
799 Fix regression which caused configuration like
800 --address=/.domain.com/1.2.3.4 to be rejected. The dot to the
801 left of the domain has been implied and not required for a
802 long time, but it should be accepted for backward
803 compatibility. Thanks to Andrew Burcin for spotting this.
804
805 Add --rebind-domain-ok and --rebind-localhost-ok.
806 Suggestion from Clemens Fischer.
807
808 Log replies to queries of type TXT, when --log-queries
809 is set.
810
811 Fix compiler warnings when compiled with -DNO_DHCP. Thanks
812 to Shantanu Gadgil for the patch.
813
814 Updated French translation. Thanks to Gildas Le Nadan.
815
816 Updated Polish translation. Thanks to Jan Psota.
817
818 Updated German translation. Thanks to Matthias Andree.
819
820 Added contrib/static-arp, thanks to Darren Hoo.
821
822 Fix corruption of the domain when a name from /etc/hosts
823 overrides one supplied by a DHCP client. Thanks to Fedor
824 Kozhevnikov for spotting the problem.
825
826 Updated Spanish translation. Thanks to Chris Chatham.
827
828
Simon Kelley316e2732010-01-22 20:16:09 +0000829version 2.52
830 Work around a Linux kernel bug which insists that the
831 length of the option passed to setsockopt must be at least
832 sizeof(int) bytes, even if we're calling SO_BINDTODEVICE
833 and the device name is "lo". Note that this is fixed
834 in kernel 2.6.31, but the workaround is harmless and
835 allows earlier kernels to be used. Also fix dnsmasq
836 bug which reported the wrong address when this failed.
837 Thanks to Fedor for finding this.
838
839 The API for IPv6 PKTINFO changed around Linux kernel
840 2.6.14. Workaround the case where dnsmasq is compiled
841 against newer headers, but then run on an old kernel:
842 necessary for some *WRT distros.
843
844 Re-read the set of network interfaces when re-loading
845 /etc/resolv.conf if --bind-interfaces is not set. This
846 handles the case that loopback interfaces do not exist
847 when dnsmasq is first started.
848
849 Tweak the PXE code to support port 4011. This should
850 reduce broadcasts and make things more reliable when other
851 servers are around. It also improves inter-operability
852 with certain clients.
853
854 Make a pxe-service configuration with no filename or boot
855 service type legal: this does a local boot. eg.
856 pxe-service=x86PC, "Local boot"
857
858 Be more conservative in detecting "A for A"
859 queries. Dnsmasq checks if the name in a type=A query looks
860 like a dotted-quad IP address and answers the query itself
861 if so, rather than forwarding it. Previously dnsmasq
862 relied in the library function inet_addr() to convert
863 addresses, and that will accept some things which are
864 confusing in this context, like 1.2.3 or even just
865 1234. Now we only do A for A processing for four decimal
866 numbers delimited by dots.
867
868 A couple of tweaks to fix compilation on Solaris. Thanks
869 to Joel Macklow for help with this.
870
871 Another Solaris compilation tweak, needed for Solaris
872 2009.06. Thanks to Lee Essen for that.
873
874 Added extract packaging stuff from Lee Essen to
875 contrib/Solaris10.
876
877 Increased the default limit on number of leases to 1000
878 (from 150). This is mainly a defence against DoS attacks,
879 and for the average "one for two class C networks"
880 installation, IP address exhaustion does that just as
881 well. Making the limit greater than the number of IP
882 addresses available in such an installation removes a
883 surprise which otherwise can catch people out.
884
885 Removed extraneous trailing space in the value of the
886 DNSMASQ_TIME_REMAINING DNSMASQ_LEASE_LENGTH and
887 DNSMASQ_LEASE_EXPIRES environment variables. Thanks to
888 Gildas Le Nadan for spotting this.
889
890 Provide the network-id tags for a DHCP transaction to
891 the lease-change script in the environment variable
892 DNSMASQ_TAGS. A good suggestion from Gildas Le Nadan.
893
894 Add support for RFC3925 "Vendor-Identifying Vendor
895 Options". The syntax looks like this:
896 --dhcp-option=vi-encap:<enterprise number>, .........
897
898 Add support to --dhcp-match to allow matching against
899 RFC3925 "Vendor-Identifying Vendor Classes". The syntax
900 looks like this:
901 --dhcp-match=tag,vi-encap<enterprise number>, <value>
902
903 Add some application specific code to assist in
904 implementing the Broadband forum TR069 CPE-WAN
905 specification. The details are in contrib/CPE-WAN/README
906
907 Increase the default DNS packet size limit to 4096, as
908 recommended by RFC5625 section 4.4.3. This can be
909 reconfigured using --edns-packet-max if needed. Thanks to
910 Francis Dupont for pointing this out.
911
Simon Kelley8ef5ada2010-06-03 19:42:45 +0100912 Rewrite query-ids even for TSIG signed packets, since
Simon Kelley316e2732010-01-22 20:16:09 +0000913 this is allowed by RFC5625 section 4.5.
914
915 Use getopt_long by default on OS X. It has been supported
916 since version 10.3.0. Thanks to Arek Dreyer for spotting
917 this.
918
919 Added up-to-date startup configuration for MacOSX/launchd
920 in contrib/MacOSX-launchd. Thanks to Arek Dreyer for
921 providing this.
922
923 Fix link error when including Dbus but excluding DHCP.
924 Thanks to Oschtan for the bug report.
925
926 Updated French translation. Thanks to Gildas Le Nadan.
927
928 Updated Polish translation. Thanks to Jan Psota.
929
930 Updated Spanish translation. Thanks to Chris Chatham.
931
Simon Kelley8ef5ada2010-06-03 19:42:45 +0100932 Fixed confusion about domains, when looking up DHCP hosts
933 in /etc/hosts. This could cause spurious "Ignoring
934 domain..." messages. Thanks to Fedor Kozhevnikov for
935 finding and analysing the problem.
Simon Kelley316e2732010-01-22 20:16:09 +0000936
Simon Kelley8ef5ada2010-06-03 19:42:45 +0100937
Simon Kelley1f15b812009-10-13 17:49:32 +0100938version 2.51
939 Add support for internationalised DNS. Non-ASCII characters
940 in domain names found in /etc/hosts, /etc/ethers and
941 /etc/dnsmasq.conf will be correctly handled by translation to
942 punycode, as specified in RFC3490. This function is only
943 available if dnsmasq is compiled with internationalisation
944 support, and adds a dependency on GNU libidn. Without i18n
945 support, dnsmasq continues to be compilable with just
946 standard tools. Thanks to Yves Dorfsman for the
947 suggestion.
948
949 Add two more environment variables for lease-change scripts:
950 First, DNSMASQ_SUPPLIED_HOSTNAME; this is set to the hostname
951 supplied by a client, even if the actual hostname used is
952 over-ridden by dhcp-host or dhcp-ignore-names directives.
953 Also DNSMASQ_RELAY_ADDRESS which gives the address of
954 a DHCP relay, if used.
955 Suggestions from Michael Rack.
956
957 Fix regression which broke echo of relay-agent
958 options. Thanks to Michael Rack for spotting this.
959
960 Don't treat option 67 as being interchangeable with
961 dhcp-boot parameters if it's specified as
962 dhcp-option-force.
963
964 Make the code to call scripts on lease-change compile-time
965 optional. It can be switched off by editing src/config.h
966 or building with "make COPTS=-DNO_SCRIPT".
967
968 Make the TFTP server cope with filenames from Windows/DOS
969 which use '\' as pathname separator. Thanks to Ralf for
970 the patch.
971
972 Updated Polish translation. Thanks to Jan Psota.
973
974 Warn if an IP address is duplicated in /etc/ethers. Thanks
975 to Felix Schwarz for pointing this out.
976
977 Teach --conf-dir to take an option list of file suffices
978 which will be ignored when scanning the directory. Useful
979 for backup files etc. Thanks to Helmut Hullen for the
980 suggestion.
981
982 Add new DHCP option named tftpserver-address, which
983 corresponds to the third argument of dhcp-boot. This
984 allows the complete functionality of dhcp-boot to be
985 replicated with dhcp-option. Useful when using
986 dhcp-optsfile.
987
988 Test which upstream nameserver to use every 10 seconds
989 or 50 queries and not just when a query times out and
990 is retried. This should improve performance when there
991 is a slow nameserver in the list. Thanks to Joe for the
992 suggestion.
993
994 Don't do any PXE processing, even for clients with the
995 correct vendorclass, unless at least one pxe-prompt or
996 pxe-service option is given. This stops dnsmasq
997 interfering with proxy PXE subsystems when it is just
998 the DHCP server. Thanks to Spencer Clark for spotting this.
999
1000 Limit the blocksize used for TFTP transfers to a value
1001 which avoids packet fragmentation, based on the MTU of the
1002 local interface. Many netboot ROMs can't cope with
1003 fragmented packets.
1004
1005 Honour dhcp-ignore configuration for PXE and proxy-PXE
1006 requests. Thanks to Niels Basjes for the bug report.
1007
1008 Updated French translation. Thanks to Gildas Le Nadan.

Simon Kelley1f15b812009-10-13 17:49:32 +01001012 Fix security problem which allowed any host permitted to
Simon Kelley77e94da2009-08-31 17:32:17 +01001013 do TFTP to possibly compromise dnsmasq by remote buffer
1014 overflow when TFTP enabled. Thanks to Core Security
1015 Technologies and Iván Arce, Pablo Hernán Jorge, Alejandro
1016 Pablo Rodriguez, Martín Coco, Alberto Soliño Testa and
1017 Pablo Annetta. This problem has Bugtraq id: 36121
1018 and CVE: 2009-2957
1019
1020 Fix a problem which allowed a malicious TFTP client to
1021 crash dnsmasq. Thanks to Steve Grubb at Red Hat for
1022 spotting this. This problem has Bugtraq id: 36120 and
1023 CVE: 2009-2958

Simon Kelley03a97b62009-06-10 20:55:49 +01001026version 2.49
1027 Fix regression in 2.48 which disables the lease-change
1028 script. Thanks to Jose Luis Duran for spotting this.
1029
1030 Log TFTP "file not found" errors. These were not logged,
1031 since a normal PXELinux boot generates many of them, but
1032 the lack of the messages seems to be more confusing than
1033 routinely seeing them when there is no real error.
1034
1035 Update Spanish translation. Thanks to Chris Chatham.

Simon Kelley7622fc02009-06-04 20:32:05 +01001038version 2.48
1039 Archived the extensive, backwards, changelog to
1040 CHANGELOG.archive. The current changelog now runs from
1041 version 2.43 and runs conventionally.
Simon Kelley9e4abcb2004-01-22 19:47:41 +00001042
Simon Kelley7622fc02009-06-04 20:32:05 +01001043 Fixed bug which broke binding of servers to physical
1044 interfaces when interface names were longer than four
1045 characters. Thanks to MURASE Katsunori for the patch.
Simon Kelley9e4abcb2004-01-22 19:47:41 +00001046
Simon Kelley7622fc02009-06-04 20:32:05 +01001047 Fixed netlink code to check that messages come from the
1048 correct source, and not another userspace process. Thanks
1049 to Steve Grubb for the patch.
Simon Kelley9e4abcb2004-01-22 19:47:41 +00001050
Simon Kelley7622fc02009-06-04 20:32:05 +01001051 Maintainability drive: removed bug and missing feature
1052 workarounds for some old platforms. Solaris 9, OpenBSD
1053 older than 4.1, Glibc older than 2.2, Linux 2.2.x and
1054 DBus older than 1.1.x are no longer supported.
Simon Kelley9e4abcb2004-01-22 19:47:41 +00001055
Simon Kelley7622fc02009-06-04 20:32:05 +01001056 Don't read included configuration files more than once:
1057 allows complex configuration structures without problems.
Simon Kelley9e4abcb2004-01-22 19:47:41 +00001058
Simon Kelley7622fc02009-06-04 20:32:05 +01001059 Mark log messages from the various subsystems in dnsmasq:
1060 messages from the DHCP subsystem now have the ident string
1061 "dnsmasq-dhcp" and messages from TFTP have ident
1062 "dnsmasq-tftp". Thanks to Olaf Westrik for the patch.
Simon Kelley9e4abcb2004-01-22 19:47:41 +00001063
Simon Kelley7622fc02009-06-04 20:32:05 +01001064 Fix possible infinite DHCP protocol loop when an IP
1065 address nailed to a hostname (not a MAC address) and a
1066 host sometimes provides the name, sometimes not.
Simon Kelley9e4abcb2004-01-22 19:47:41 +00001067
Simon Kelley7622fc02009-06-04 20:32:05 +01001068 Allow --addn-hosts to take a directory: all the files
1069 in the directory are read. Thanks to Phil Cornelius for
1070 the suggestion.
Simon Kelley9e4abcb2004-01-22 19:47:41 +00001071
Simon Kelley7622fc02009-06-04 20:32:05 +01001072 Support --bridge-interface on all platforms, not just BSD.
Simon Kelley1ab84e22004-01-29 16:48:35 +00001073
Simon Kelley7622fc02009-06-04 20:32:05 +01001074 Added support for advanced PXE functions. It's now
1075 possible to define a prompt and menu options which will
1076 be displayed when a client PXE boots. It's also possible to
1077 hand-off booting to other boot servers. Proxy-DHCP, where
1078 dnsmasq just supplies the PXE information and another DHCP
1079 server does address allocation, is also allowed. See the
1080 --pxe-prompt and --pxe-service keywords. Thanks to
1081 Alkis Georgopoulos for the suggestion and Guilherme Moro
1082 and Michael Brown for assistance.
Simon Kelley1ab84e22004-01-29 16:48:35 +00001083
Simon Kelley7622fc02009-06-04 20:32:05 +01001084 Improvements to DHCP logging. Thanks to Tom Metro for
1085 useful suggestions.
1086
1087 Add ability to build dnsmasq without DHCP support. To do
1088 this, edit src/config.h or build with
1089 "make COPTS=-DNO_DHCP". Thanks to Mahavir Jain for the patch.
1090
1091 Added --test command-line switch - syntax check
1092 configuration files only.
Simon Kelley33820b72004-04-03 21:10:00 +01001093
Simon Kelley7622fc02009-06-04 20:32:05 +01001094 Updated French translation. Thanks to Gildas Le Nadan.

1097version 2.47
1098 Updated French translation. Thanks to Gildas Le Nadan.
1099
1100 Fixed interface enumeration code to work on NetBSD
1101 5.0. Thanks to Roy Marples for the patch.
1102
1103 Updated config.h to use the same location for the lease
1104 file on NetBSD as the other *BSD variants. Also allow
1105 LEASEFILE and CONFFILE symbols to be overriden in CFLAGS.
1106
1107 Handle duplicate address detection on IPv6 more
1108 intelligently. In IPv6, an interface can have an address
1109 which is not usable, because it is still undergoing DAD
1110 (such addresses are marked "tentative"). Attempting to
1111 bind to an address in this state returns an error,
1112 EADDRNOTAVAIL. Previously, on getting such an error,
1113 dnsmasq would silently abandon the address, and never
1114 listen on it. Now, it retries once per second for 20
1115 seconds before generating a fatal error. 20 seconds should
1116 be long enough for any DAD process to complete, but can be
1117 adjusted in src/config.h if necessary. Thanks to Martin
1118 Krafft for the bug report.
1119
1120 Add DBus introspection. Patch from Jeremy Laine.
1121
1122 Update Dbus configuration file. Patch from Colin Walters.
1123 Fix for this bug:
1124 http://bugs.freedesktop.org/show_bug.cgi?id=18961
1125
1126 Support arbitrarily encapsulated DHCP options, suggestion
1127 and initial patch from Samium Gromoff. This is useful for
1128 (eg) gPXE, which expect all its private options to be
1129 encapsulated inside a single option 175. So, eg,
1130
1131 dhcp-option = encap:175, 190, "iscsi-client0"
1132 dhcp-option = encap:175, 191, "iscsi-client0-secret"
1133
1134 will provide iSCSI parameters to gPXE.
1135
1136 Enhance --dhcp-match to allow testing of the contents of a
1137 client-sent option, as well as its presence. This
1138 application in mind for this is RFC 4578
1139 client-architecture specifiers, but it's generally useful.
1140 Joey Korkames suggested the enhancement.
1141
1142 Move from using the IP_XMIT_IF ioctl to IP_BOUND_IF on
1143 OpenSolaris. Thanks to Bastian Machek for the heads-up.
1144
1145 No longer complain about blank lines in
1146 /etc/ethers. Thanks to Jon Nelson for the patch.
1147
1148 Fix binding of servers to physical devices, eg
1149 --server=/domain/1.2.3.4@eth0 which was broken from 2.43
1150 onwards unless --query-port=0 set. Thanks to Peter Naulls
1151 for the bug report.
1152
1153 Reply to DHCPINFORM requests even when the supplied ciaddr
1154 doesn't fall in any dhcp-range. In this case it's not
1155 possible to supply a complete configuration, but
1156 individually-configured options (eg PAC) may be useful.
1157
1158 Allow the source address of an alias to be a range:
1159 --alias=192.168.0.0,10.0.0.0,255.255.255.0 maps the whole
1160 subnet 192.168.0.0->192.168.0.255 to 10.0.0.0->10.0.0.255,
1161 as before.
1162 --alias=192.168.0.10-192.168.0.40,10.0.0.0,255.255.255.0
1163 maps only the 192.168.0.10->192.168.0.40 region. Thanks to
1164 Ib Uhrskov for the suggestion.
1165
1166 Don't dynamically allocate DHCP addresses which may break
1167 Windows. Addresses which end in .255 or .0 are broken in
1168 Windows even when using supernetting.
1169 --dhcp-range=192.168.0.1,192.168.1.254,255,255,254.0 means
1170 192.168.0.255 is a valid IP address, but not for Windows.
1171 See Microsoft KB281579. We therefore no longer allocate
1172 these addresses to avoid hard-to-diagnose problems.
1173
1174 Update Polish translation. Thanks to Jan Psota.
1175
1176 Delete the PID-file when dnsmasq shuts down. Note that by
1177 this time, dnsmasq is normally not running as root, so
1178 this will fail if the PID-file is stored in a root-owned
1179 directory; such failure is silently ignored. To take
1180 advantage of this feature, the PID-file must be stored in a
1181 directory owned and write-able by the user running
1182 dnsmasq.
Simon Kelley7622fc02009-06-04 20:32:05 +01001183
1184
1185version 2.46
1186 Allow --bootp-dynamic to take a netid tag, so that it may
1187 be selectively enabled. Thanks to Olaf Westrik for the
1188 suggestion.
1189
1190 Remove ISC-leasefile reading code. This has been
1191 deprecated for a long time, and last time I removed it, it
1192 ended up going back by request of one user. This time,
1193 it's gone for good; otherwise it would need to be
1194 re-worked to support multiple domains (see below).
1195
1196 Support DHCP clients in multiple DNS domains. This is a
1197 long-standing request. Clients are assigned to a domain
1198 based in their IP address.
1199
1200 Add --dhcp-fqdn flag, which changes behaviour if DNS names
1201 assigned to DHCP clients. When this is set, there must be
1202 a domain associated with each client, and only
1203 fully-qualified domain names are added to the DNS. The
1204 advantage is that the only the FQDN needs to be unique,
1205 so that two or more DHCP clients can share a hostname, as
1206 long as they are in different domains.
1207
1208 Set environment variable DNSMASQ_DOMAIN when invoking
1209 lease-change script. This may be useful information to
1210 have now that it's variable.
1211
1212 Tighten up data-checking code for DNS packet
1213 handling. Thanks to Steve Dodd who found certain illegal
1214 packets which could crash dnsmasq. No memory overwrite was
1215 possible, so this is not a security issue beyond the DoS
1216 potential.
1217
1218 Update example config dhcp option 47, the previous
1219 suggestion generated an illegal, zero-length,
1220 option. Thanks to Matthias Andree for finding this.
1221
1222 Rewrite hosts-file reading code to remove the limit of
1223 1024 characters per line. John C Meuser found this.
1224
1225 Create a net-id tag with the name of the interface on
1226 which the DHCP request was received.
1227
1228 Fixed minor memory leak in DBus code, thanks to Jeremy
1229 Laine for the patch.
1230
1231 Emit DBus signals as the DHCP lease database
1232 changes. Thanks to Jeremy Laine for the patch.
1233
1234 Allow for more that one MAC address in a dhcp-host
1235 line. This configuration tells dnsmasq that it's OK to
1236 abandon a DHCP lease of the fixed address to one MAC
1237 address, if another MAC address in the dhcp-host statement
1238 asks for an address. This is useful to give a fixed
1239 address to a host which has two network interfaces
1240 (say, a laptop with wired and wireless interfaces.)
1241 It's very important to ensure that only one interface
1242 at a time is up, since dnsmasq abandons the first lease
1243 and re-uses the address before the leased time has
1244 elapsed. John Gray suggested this.
1245
1246 Tweak the response to a DHCP request packet with a wrong
1247 server-id when --dhcp-authoritative is set; dnsmasq now
1248 returns a DHCPNAK, rather than silently ignoring the
1249 packet. Thanks to Chris Marget for spotting this
1250 improvement.
1251
1252 Add --cname option. This provides a limited alias
1253 function, usable for DHCP names. Thanks to AJ Weber for
1254 suggestions on this.
1255
1256 Updated contrib/webmin with latest version from Neil
1257 Fisher.
1258
1259 Updated Polish translation. Thanks to Jan Psota.
1260
1261 Correct the text names for DHCP options 64 and 65 to be
1262 "nis+-domain" and "nis+-servers".
1263
1264 Updated Spanish translation. Thanks to Chris Chatham.

1267 up" event occurs.

1271 Fix total DNS failure in release 2.44 unless --min-port

1273 bugreport. Also reject out-of-range port spec, which could
1274 break things too: suggestion from Gilles Espinasse.
1275

1277version 2.44
1278 Fix crash when unknown client attempts to renew a DHCP
1279 lease, problem introduced in version 2.43. Thanks to
1280 Carlos Carvalho for help chasing this down.
1281
1282 Fix potential crash when a host which doesn't have a lease
1283 does DHCPINFORM. Again introduced in 2.43. This bug has
1284 never been reported in the wild.
1285
1286 Fix crash in netlink code introduced in 2.43. Thanks to
1287 Jean Wolter for finding this.
1288
1289 Change implementation of min_port to work even if min-port
1290 is large.

1307 format.
1308
1309 Honour lease-time spec in dhcp-host lines even for
1310 BOOTP. The user is assumed to known what they are doing in
1311 this case. (Hosts without the time spec still get infinite
1312 leases for BOOTP, over-riding the default in the
1313 dhcp-range.) Thanks to Peter Katzmann for uncovering this.
1314
1315 Fix problem matching relay-agent ids. Thanks to Michael
1316 Rack for the bug report.
1317
1318 Add --naptr-record option. Suggestion from Johan
1319 Bergquist.
1320
1321 Implement RFC 5107 server-id-override DHCP relay agent
1322 option.
1323
1324 Apply patches from Stefan Kruger for compilation on
1325 Solaris 10 under Sun studio.
1326
1327 Yet more tweaking of Linux capability code, to suppress
1328 pointless wingeing from kernel 2.6.25 and above.
1329
1330 Improve error checking during startup. Previously, some
1331 errors which occurred during startup would be worked
1332 around, with dnsmasq still starting up. Some were logged,
1333 some silent. Now, they all cause a fatal error and dnsmasq
1334 terminates with a non-zero exit code. The errors are those
1335 associated with changing uid and gid, setting process
1336 capabilities and writing the pidfile. Thanks to Uwe
1337 Gansert and the Suse security team for pointing out
1338 this improvement, and Bill Reimers for good implementation
1339 suggestions.
1340
1341 Provide NO_LARGEFILE compile option to switch off largefile
1342 support when compiling against versions of uclibc which
1343 don't support it. Thanks to Stephane Billiart for the patch.
1344
1345 Implement random source ports for interactions with
1346 upstream nameservers. New spoofing attacks have been found
1347 against nameservers which do not do this, though it is not
1348 clear if dnsmasq is vulnerable, since to doesn't implement
1349 recursion. By default dnsmasq will now use a different
1350 source port (and socket) for each query it sends
1351 upstream. This behaviour can suppressed using the
1352 --query-port option, and the old default behaviour
1353 restored using --query-port=0. Explicit source-port
1354 specifications in --server configs are still honoured.
1355
1356 Replace the random number generator, for better
1357 security. On most BSD systems, dnsmasq uses the
1358 arc4random() RNG, which is secure, but on other platforms,
1359 it relied on the C-library RNG, which may be
1360 guessable and therefore allow spoofing. This release
1361 replaces the libc RNG with the SURF RNG, from Daniel
1362 J. Berstein's DJBDNS package.
1363
1364 Don't attempt to change user or group or set capabilities
1365 if dnsmasq is run as a non-root user. Without this, the
1366 change from soft to hard errors when these fail causes
1367 problems for non-root daemons listening on high
1368 ports. Thanks to Patrick McLean for spotting this.
1369
1370 Updated French translation. Thanks to Gildas Le Nadan.
