Simon Kelley9d1b22a2014-04-29 13:02:41 +01008version 2.71
9 Subtle change to error handling to help DNSSEC validation
10 when servers fail to provide NODATA answers for
11 non-existent DS records.
12
13 Tweak code which removes DNSSEC records from answers when
14 not required. Fixes broken answers when additional section
15 has real records in it. Thanks to Marco Davids for the bug
16 report.
17
18 Fix DNSSEC validation of ANY queries. Thanks to Marco Davids
19 for spotting that too.
20
Simon Kelleyb692f232014-05-09 10:29:43 +010021 Fix total DNS failure and 100% CPU use if cachesize set to zero,
22 regression introduced in 2.69. Thanks to James Hunt and
23 the Ubuntu crowd for assistance in fixing this.

Simon Kelley63758382014-04-16 22:20:55 +010026version 2.70
27 Fix crash, introduced in 2.69, on TCP request when dnsmasq
28 compiled with DNSSEC support, but running without DNSSEC
29 enabled. Thanks to Manish Sing for spotting that one.
30
Simon Kelley3b1b3e92014-04-23 15:46:05 +010031 Fix regression which broke ipset functionality. Thanks to
32 Wang Jian for the bug report.

Simon Kelley1ee9be42013-12-09 16:50:19 +000035version 2.69
36 Implement dynamic interface discovery on *BSD. This allows
37 the contructor: syntax to be used in dhcp-range for DHCPv6
38 on the BSD platform. Thanks to Matthias Andree for
39 valuable research on how to implement this.

Simon Kelley8db957d2013-12-17 15:47:10 +000041 Fix infinite loop associated with some --bogus-nxdomain
Simon Kelley74e6b522013-12-17 21:33:53 +000042 configs. Thanks fogobogo for the bug report.
Simon Kelley8db957d2013-12-17 15:47:10 +000043
Simon Kelleyae762422014-01-10 18:15:16 +000044 Fix missing RA RDNS option with configuration like
45 --dhcp-option=option6:23,[::] Thanks to Tsachi Kimeldorfer
46 for spotting the problem.
47
Simon Kelleyc3a04082014-01-11 22:18:19 +000048 Add [fd00::] and [fe80::] as special addresses in DHCPv6
49 options, analogous to [::]. [fd00::] is replaced with the
50 actual ULA of the interface on the machine running
51 dnsmasq, [fe80::] with the link-local address.
52 Thanks to Tsachi Kimeldorfer for championing this.
53
Simon Kelley613d6c52014-02-04 11:50:11 +000054 DNSSEC validation and caching. Dnsmasq needs to be
55 compiled with this enabled, with
56
57 make dnsmasq COPTS=-DHAVE_DNSSEC
58
59 this add dependencies on the nettle crypto library and the
60 gmp maths library. It's possible to have these linked
61 statically with
62
63 make dnsmasq COPTS='-DHAVE_DNSSEC -DHAVE_DNSSEC_STATIC'
64
Simon Kelley198d9402014-04-09 20:36:53 +010065 which bloats the dnsmasq binary, but saves the size of
66 the shared libraries which are much bigger.
67
Simon Kelley613d6c52014-02-04 11:50:11 +000068 To enable, DNSSEC, you will need a set of
69 trust-anchors. Now that the TLDs are signed, this can be
70 the keys for the root zone, and for convenience they are
71 included in trust-anchors.conf in the dnsmasq
72 distribution. You should of course check that these are
73 legitimate and up-to-date. So, adding
74
75 conf-file=/path/to/trust-anchors.conf
76 dnssec
Simon Kelley1ee9be42013-12-09 16:50:19 +000077
Simon Kelley613d6c52014-02-04 11:50:11 +000078 to your config is all thats needed to get things
79 working. The upstream nameservers have to be DNSSEC-capable
80 too, of course. Many ISP nameservers aren't, but the
81 Google public nameservers (8.8.8.8 and 8.8.4.4) are.
82 When DNSSEC is configured, dnsmasq validates any queries
83 for domains which are signed. Query results which are
84 bogus are replaced with SERVFAIL replies, and results
85 which are correctly signed have the AD bit set. In
86 addition, and just as importantly, dnsmasq supplies
87 correct DNSSEC information to clients which are doing
88 their own validation, and caches DNSKEY, DS and RRSIG
89 records, which significantly improve the performance of
90 downstream validators. Setting --log-queries will show
91 DNSSEC in action.
92
Simon Kelley198d9402014-04-09 20:36:53 +010093 If a domain is returned from an upstream nameserver without
94 DNSSEC signature, dnsmasq by default trusts this. This
95 means that for unsigned zone (still the majority) there
96 is effectively no cost for having DNSSEC enabled. Of course
97 this allows an attacker to replace a signed record with a
98 false unsigned record. This is addressed by the
99 --dnssec-check-unsigned flag, which instructs dnsmasq
100 to prove that an unsigned record is legitimate, by finding
101 a secure proof that the zone containing the record is not
102 signed. Doing this has costs (typically one or two extra
103 upstream queries). It also has a nasty failure mode if
104 dnsmasq's upstream nameservers are not DNSSEC capable.
105 Without --dnssec-check-unsigned using such an upstream
106 server will simply result in not queries being validated;
107 with --dnssec-check-unsigned enabled and a
108 DNSSEC-ignorant upstream server, _all_ queries will fail.
109
110 Note that DNSSEC requires that the local time is valid and
111 accurate, if not then DNSSEC validation will fail. NTP
112 should be running. This presents a problem for routers
113 without a battery-backed clock. To set the time needs NTP
114 to do DNS lookups, but lookups will fail until NTP has run.
115 To address this, there's a flag, --dnssec-no-timecheck
116 which disables the time checks (only) in DNSSEC. When dnsmasq
117 is started and the clock is not synced, this flag should
118 be used. As soon as the clock is synced, SIGHUP dnsmasq.
119 The SIGHUP clears the cache of partially-validated data and
120 resets the no-timecheck flag, so that all DNSSEC checks
121 henceforward will be complete.
122
Simon Kelley613d6c52014-02-04 11:50:11 +0000123 The development of DNSSEC in dnsmasq was started by
124 Giovanni Bajo, to whom huge thanks are owed. It has been
125 supported by Comcast, whose techfund grant has allowed for
126 an invaluable period of full-time work to get it to
127 a workable state.
128
Simon Kelleyde73a492014-02-17 21:43:27 +0000129 Add --rev-server. Thanks to Dave Taht for suggesting this.
Simon Kelley7b1eae42014-02-20 13:43:28 +0000130
131 Add --servers-file. Allows dynamic update of upstream servers
132 full access to configuration.
Simon Kelleyde73a492014-02-17 21:43:27 +0000133
Simon Kelleyc8a80482014-03-05 14:29:54 +0000134 Add --local-service. Accept DNS queries only from hosts
135 whose address is on a local subnet, ie a subnet for which
136 an interface exists on the server. This option
Simon Kelleyf00690f2014-03-12 20:07:12 +0000137 only has effect if there are no --interface --except-interface,
Simon Kelleyc8a80482014-03-05 14:29:54 +0000138 --listen-address or --auth-server options. It is intended
139 to be set as a default on installation, to allow
140 unconfigured installations to be useful but also safe from
141 being used for DNS amplification attacks.
142
Simon Kelley604f7592014-03-22 19:33:43 +0000143 Fix crashes in cache_get_cname_target() when dangling CNAMEs
144 encountered. Thanks to Andy and the rt-n56u project for
145 find this and helping to chase it down.
146
Simon Kelley10068602014-04-03 21:16:40 +0100147 Fix wrong RCODE in authoritative DNS replies to PTR queries. The
148 correct answer was included, but the RCODE was set to NXDOMAIN.
149 Thanks to Craig McQueen for spotting this.
150
Simon Kelley198d9402014-04-09 20:36:53 +0100151 Make statistics available as DNS queries in the .bind TLD as
152 well as logging them.
153
Simon Kelleyc8a80482014-03-05 14:29:54 +0000154
Simon Kelley376d48c2013-11-13 13:04:30 +0000155version 2.68
156 Use random addresses for DHCPv6 temporary address
157 allocations, instead of algorithmically determined stable
158 addresses.
159
160 Fix bug which meant that the DHCPv6 DUID was not available
161 in DHCP script runs during the lifetime of the dnsmasq
162 process which created the DUID de-novo. Once the DUID was
163 created and stored in the lease file and dnsmasq
164 restarted, this bug disappeared.
165
166 Fix bug introduced in 2.67 which could result in erroneous
167 NXDOMAIN returns to CNAME queries.
168
169 Fix build failures on MacOS X and openBSD.
170
171 Allow subnet specifications in --auth-zone to be interface
172 names as well as address literals. This makes it possible
173 to configure authoritative DNS when local address ranges
174 are dynamic and works much better than the previous
175 work-around which exempted contructed DHCP ranges from the
176 IP address filtering. As a consequence, that work-around
177 is removed. Under certain circumstances, this change wil
178 break existing configuration: if you're relying on the
179 contructed-range exception, you need to change --auth-zone
180 to specify the same interface as is used to construct your
181 DHCP ranges, probably with a trailing "/6" like this:
182 --auth-zone=example.com,eth0/6 to limit the addresses to
183 IPv6 addresses of eth0.
Simon Kelleydd9d9ce2013-11-15 11:24:00 +0000184
185 Fix problems when advertising deleted IPv6 prefixes. If
186 the prefix is deleted (rather than replaced), it doesn't
187 get advertised with zero preferred time. Thanks to Tsachi
188 for the bug report.
Simon Kelley25439062013-11-25 21:14:51 +0000189
190 Fix segfault with some locally configured CNAMEs. Thanks
191 to Andrew Childs for spotting the problem.
192
193 Fix memory leak on re-reading /etc/hosts and friends,
194 introduced in 2.67.
Simon Kelley2329bef2013-12-03 13:41:16 +0000195
196 Check the arrival interface of incoming DNS and TFTP
197 requests via IPv6, even in --bind-interfaces mode. This
198 isn't possible for IPv4 and can generate scary warnings,
199 but as it's always possible for IPv6 (the API always
200 exists) then we should do it always.
Vladislav Grishenko4c82efc2013-12-03 16:05:30 +0000201
202 Tweak the rules on prefix-lengths in --dhcp-range for
203 IPv6. The new rule is that the specified prefix length
204 must be larger than or equal to the prefix length of the
205 corresponding address on the local interface.
206
Simon Kelley376d48c2013-11-13 13:04:30 +0000207
Giacomo Tazzari797a7af2013-04-22 13:16:37 +0100208version 2.67
209 Fix crash if upstream server returns SERVFAIL when
210 --conntrack in use. Thanks to Giacomo Tazzari for finding
211 this and supplying the patch.
Simon Kelleyaa63a212013-04-22 15:01:52 +0100212
213 Repair regression in 2.64. That release stopped sending
214 lease-time information in the reply to DHCPINFORM
215 requests, on the correct grounds that it was a standards
216 violation. However, this broke the dnsmasq-specific
217 dhcp_lease_time utility. Now, DHCPINFORM returns
218 lease-time only if it's specifically requested
219 (maintaining standards) and the dhcp_lease_time utility
220 has been taught to ask for it (restoring functionality).
Simon Kelley86e92f92013-04-23 11:31:39 +0100221
222 Fix --dhcp-match, --dhcp-vendorclass and --dhcp-userclass
223 to work with BOOTP and well as DHCP. Thanks to Peter
224 Korsgaard for spotting the problem.
Simon Kelley2bb73af2013-04-24 17:38:19 +0100225
226 Add --synth-domain. Thanks to Vishvananda Ishaya for
227 suggesting this.
Simon Kelleyd5052fb2013-04-25 12:44:20 +0100228
229 Fix failure to compile ipset.c if old kernel headers are
230 in use. Thanks to Eugene Rudoy for pointing this out.
Simon Kelley3f2873d2013-05-14 11:28:47 +0100231
232 Handle IPv4 interface-address labels in Linux. These are
233 often used to emulate the old IP-alias addresses. Before,
234 using --interface=eth0 would service all the addresses of
235 eth0, including ones configured as aliases, which appear
236 in ifconfig as eth0:0. Now, only addresses with the label
237 eth0 are active. This is not backwards compatible: if you
238 want to continue to bind the aliases too, you need to add
239 eg. --interface=eth0:0 to the config.
Giacomo Tazzari797a7af2013-04-22 13:16:37 +0100240
Simon Kelleycfcad422013-05-17 11:32:03 +0100241 Fix "failed to set SO_BINDTODEVICE on DHCP socket: Socket
242 operation on non-socket" error on startup with
243 configurations which have exactly one --interface option
244 and do RA but _not_ DHCPv6. Thanks to Trever Adams for the
245 bug report.
Giacomo Tazzari797a7af2013-04-22 13:16:37 +0100246
Simon Kelley115ac3e2013-05-20 11:28:32 +0100247 Generalise --interface-name to cope with IPv6 addresses
248 and multiple addresses per interface per address family.
249
Simon Kelley3e8ed782013-05-29 14:31:33 +0100250 Fix option parsing for --dhcp-host, which was generating a
251 spurious error when all seven possible items were
252 included. Thanks to Zhiqiang Wang for the bug report.
Simon Kelleybaa80ae2013-05-29 16:32:07 +0100253
254 Remove restriction on prefix-length in --auth-zone. Thanks
255 to Toke Hoiland-Jorgensen for suggesting this.
256
Marcelo Salhab Brogliato0da5e892013-05-31 11:49:06 +0100257 Log when the maximum number of concurrent DNS queries is
258 reached. Thanks to Marcelo Salhab Brogliato for the patch.
259
Simon Kelleye2ba0df2013-05-31 17:04:25 +0100260 If wildcards are used in --interface, don't assume that
261 there will only ever be one available interface for DHCP
262 just because there is one at start-up. More may appear, so
263 we can't use SO_BINDTODEVICE. Thanks to Natrio for the bug
264 report.
265
Simon Kelleyb4b93082013-06-19 10:31:23 +0100266 Increase timeout/number of retries in TFTP to accomodate
267 AudioCodes Voice Gateways doing streaming writes to flash.
268 Thanks to Damian Kaczkowski for spotting the problem.
269
Simon Kelley625ac282013-07-02 21:19:32 +0100270 Fix crash with empty DHCP string options when adding zero
Simon Kelley3953dcc2013-07-03 20:40:45 +0100271 terminator. Thanks to Patrick McLean for the bug report.
Simon Kelley625ac282013-07-02 21:19:32 +0100272
Kyle Mesteryd859ca22013-07-24 13:11:58 +0100273 Allow hostnames to start with a number, as allowed in
274 RFC-1123. Thanks to Kyle Mestery for the patch.
275
Roy Marples3f3adae2013-07-25 16:22:46 +0100276 Fixes to DHCP FQDN option handling: don't terminate FQDN
277 if domain not known and allow a FQDN option with blank
278 name to request that a FQDN option is returned in the
279 reply. Thanks to Roy Marples for the patch.
280
Simon Kelleyd9fb0be2013-07-25 21:47:17 +0100281 Make --clear-on-reload apply to setting upstream servers
282 via DBus too.
283
Simon Kelleyef1a94a2013-07-26 13:59:03 +0100284 When the address which triggered the construction of an
285 advertised IPv6 prefix disappears, continue to advertise
286 the prefix for up to 2 hours, with the preferred lifetime
287 set to zero. This satisfies RFC 6204 4.3 L-13 and makes
288 things work better if a prefix disappears without being
289 deprecated first. Thanks to Uwe Schindler for persuasively
290 arguing for this.
291
Simon Kelleyfc4c4fd2013-07-26 15:38:59 +0100292 Fix MAC address enumeration on *BSD. Thanks to Brad Smith
293 for the bug report.

Simon Kelley871d4562013-07-27 21:32:32 +0100295 Support RFC-4242 information-refresh-time options in the
296 reply to DHCPv6 information-request. The lease time of the
297 smallest valid dhcp-range is sent. Thanks to Uwe Schindler
298 for suggesting this.
299
Simon Kelleyedf0bde2013-07-29 17:21:48 +0100300 Make --listen-address higher priority than --except-interface
301 in all circumstances. Thanks to Thomas Hood for the bugreport.
302
Simon Kelley2937f8a2013-07-29 19:49:07 +0100303 Provide independent control over which interfaces get TFTP
304 service. If enable-tftp is given a list of interfaces, then TFTP
305 is provided on those. Without the list, the previous behaviour
306 (provide TFTP to the same interfaces we provide DHCP to)
307 is retained. Thanks to Lonnie Abelbeck for the suggestion.
308
Simon Kelley6acef732013-09-09 15:21:39 +0100309 Add --dhcp-relay config option. Many thanks to vtsl.net
310 for sponsoring this development.
Simon Kelleyff7eea22013-09-04 18:01:38 +0100311
Simon Kelley0932f9c2013-09-05 11:30:30 +0100312 Fix crash with empty tag: in --dhcp-range. Thanks to
313 Kaspar Schleiser for the bug report.
314
Simon Kelleyceae52d2013-09-12 15:05:47 +0100315 Add "baseline" and "bloatcheck" makefile targets, for
316 revealing size changes during development. Thanks to
317 Vladislav Grishenko for the patch.
318
Simon Kelleyc8f2dd82013-09-13 11:22:55 +0100319 Cope with DHCPv6 clients which send REQUESTs without
320 address options - treat them as SOLICIT with rapid commit.
321
Simon Kelley89500e32013-09-20 16:29:20 +0100322 Support identification of clients by MAC address in
323 DHCPv6. When using a relay, the relay must support RFC
324 6939 for this to work. It always works for directly
325 connected clients. Thanks to Vladislav Grishenko
326 for prompting this feature.
Simon Kelley861c8912013-09-25 15:30:30 +0100327
328 Remove the rule for constructed DHCP ranges that the local
329 address must be either the first or last address in the
330 range. This was originally to avoid SLAAC addresses, but
331 we now explicitly autoconfig and privacy addresses instead.
Simon Kelley89500e32013-09-20 16:29:20 +0100332
Simon Kelley889d8a12013-10-02 13:12:09 +0100333 Update Polish translation. Thanks to Jan Psota.
334
Tanguy Bouzelocef1d7422013-10-03 11:06:31 +0100335 Fix problem in DHCPv6 vendorclass/userclass matching
336 code. Thanks to Tanguy Bouzeloc for the patch.

Simon Kelleyc4cd95d2013-10-10 20:58:11 +0100340 Add --ra-param option. Thanks to Vladislav Grishenko for
341 inspiration on this.
342
Simon Kelleyed4c0762013-10-08 20:46:34 +0100343 Add --add-subnet configuration, to tell upstream DNS
Simon Kelleyf65b0e52013-10-11 10:19:01 +0100344 servers where the original client is. Thanks to DNSthingy
345 for sponsoring this feature.

Kevin Darbyshire-Bryant8c0b73d2013-10-11 11:56:33 +0100347 Add --quiet-dhcp, --quiet-dhcp6 and --quiet-ra. Thanks to
348 Kevin Darbyshire-Bryant for the initial patch.
349
Simon Kelleyd56a6042013-10-11 14:39:03 +0100350 Allow A/AAAA records created by --interface-name to be the
351 target of --cname. Thanks to Hadmut Danisch for the
352 suggestion.
353
Simon Kelley24b5a5d2013-10-11 15:19:28 +0100354 Avoid treating a --dhcp-host which has an IPv6 address
355 as eligable for use with DHCPv4 on the grounds that it has
356 no address, and vice-versa. Thanks to Yury Konovalov for
357 spotting the problem.
358
Simon Kelley45cca582013-10-15 10:20:13 +0100359 Do a better job caching dangling CNAMEs. Thanks to Yves
360 Dorfsman for spotting the problem.

Simon Kelley333b2ce2013-01-07 21:46:03 +0000363version 2.66
364 Add the ability to act as an authoritative DNS
365 server. Dnsmasq can now answer queries from the wider 'net
366 with local data, as long as the correct NS records are set
367 up. Only local data is provided, to avoid creating an open
368 DNS relay. Zone transfer is supported, to allow secondary
369 servers to be configured.
370
371 Add "constructed DHCP ranges" for DHCPv6. This is intended
372 for IPv6 routers which get prefixes dynamically via prefix
373 delegation. With suitable configuration, stateful DHCPv6
374 and RA can happen automatically as prefixes are delegated
375 and then deprecated, without having to re-write the
376 dnsmasq configuration file or restart the daemon. Thanks to
377 Steven Barth for extensive testing and development work on
378 this idea.

380 Fix crash on startup on Solaris 11. Regression probably
Simon Kelley22ce5502013-01-22 13:53:04 +0000381 introduced in 2.61. Thanks to Geoff Johnstone for the
382 patch.
383
384 Add code to make behaviour for TCP DNS requests that same
385 as for UDP requests, when a request arrives for an allowed
386 address, but via a banned interface. This change is only
387 active on Linux, since the relevant API is missing (AFAIK)
388 on other platforms. Many thanks to Tomas Hozza for
389 spotting the problem, and doing invaluable discovery of
390 the obscure and undocumented API required for the solution.
Simon Kelleya21e27b2013-02-17 16:41:35 +0000391
392 Don't send the default DHCP option advertising dnsmasq as
393 the local DNS server if dnsmasq is configured to not act
394 as DNS server, or it's configured to a non-standard port.
Simon Kelleydd1721c2013-02-18 21:04:04 +0000395
396 Add DNSMASQ_CIRCUIT_ID, DNSMASQ_SUBCRIBER_ID,
397 DNSMASQ_REMOTE_ID variables to the environment of the
Simon Kelley3d77c042013-03-22 10:03:50 +0000398 lease-change script (and the corresponding Lua). These hold
Simon Kelleydd1721c2013-02-18 21:04:04 +0000399 information inserted into the DHCP request by a DHCP relay
400 agent. Thanks to Lakefield Communications for providing a
401 bounty for this addition.
402
Simon Kelley4038ae22013-02-19 16:47:07 +0000403 Fixed crash, introduced in 2.64, whilst handling DHCPv6
404 information-requests with some common configurations.
405 Thanks to Robert M. Albrecht for the bug report and
406 chasing the problem.
407
Jason A. Donenfeld13d86c72013-02-22 18:20:53 +0000408 Add --ipset option. Thanks to Jason A. Donenfeld for the

443 Handle DHCP FQDN options with all flag bits zero and
444 --dhcp-client-update set. Thanks to Bernd Krumbroeck for
445 spotting the problem.
446
Simon Kelley12d71ed2012-08-30 15:16:41 +0100447 Finesse the check for /etc/hosts names which conflict with
448 DHCP names. Previously a name/address pair in /etc/hosts
449 which didn't match the name/address of a DHCP lease would
450 generate a warning. Now that only happesn if there is not
451 also a match. This allows multiple addresses for a name in
452 /etc/hosts with one of them assigned via DHCP.
453
Simon Kelley4d0f5b42012-09-05 23:29:30 +0100454 Fix broken vendor-option processing for BOOTP. Thanks to

Simon Kelleye4807d82012-09-27 21:52:26 +0100475 Fix breakage of --host-record parsing, resulting in
476 infinte loop at startup. Regression in 2.63. Thanks to
477 Haim Gelfenbeyn for spotting this.
478
Simon Kelley20223102012-10-15 10:41:17 +0100479 Set SO_REUSEADDRESS and SO_V6ONLY options on the DHCPv6
480 socket, this allows multiple instances of dnsmasq on a
481 single machine, in the same way as for DHCPv4. Thanks to
482 Gene Czarcinski and Vladislav Grishenko for work on this.

Simon Kelleyd1a59752012-11-05 16:50:30 +0000492 Don't include lease-time in DHCPACK replies to DHCPINFORM
493 queries, since RFC-2131 says we shouldn't. Thanks to

503 Handle better attempts to transmit on interfaces which are
504 still doing DAD, and specifically do not just transmit
505 without setting source address and interface, since this
506 can cause very puzzling effects when a router

517 start-up. Thanks to Daniel Veillard for the initial patch.
518
519 Allow more than one --tfp-root flag. The per-interface
520 stuff is pointless without that.
521
Simon Kelley54dd3932012-06-20 11:23:38 +0100522 Add --bind-dynamic. A hybrid mode between the default and
523 --bind-interfaces which copes with dynamically created
524 interfaces.

Simon Kelley8bc4cec2012-07-03 21:04:11 +0100529 Remove the interface:<interface> argument in --dhcp-range, and
530 the interface argument to --enable-tftp. These were a
531 still-born attempt to allow automatic isolated
532 configuration by libvirt, but have never (to my knowledge)
533 been used, had very strange semantics, and have been
534 superceded by other mechanisms.
535
Simon Kelleyc4a7f902012-07-12 20:52:12 +0100536 Fixed bug logging filenames when duplicate dhcp-host
537 addresses are found. Thanks to John Hanks for the patch.

Simon Kelley42243212012-07-20 15:19:18 +0100544 Teach DHCPv6 about the RFC 4242 information-refresh-time
545 option, and add parsing if the minutes, hours and days
546 format for options. Thanks to Francois-Xavier Le Bail for
547 the suggestion.
548
549 Allow "w" (for week) as multiplier in lease times, as well
550 as seconds, minutes, hours and days. Álvaro Gámez Machado
551 spotted the ommission.

587
Simon Kelleyeabc6dd2012-03-07 20:28:20 +0000588version 2.61
589 Re-write interface discovery code on *BSD to use
590 getifaddrs. This is more portable, more straightforward,
591 and allows us to find the prefix length for IPv6
592 addresses.
593
Simon Kelley01d1b8d2012-03-28 21:37:25 +0100594 Add ra-names, ra-stateless and slaac keywords for DHCPv6.
595 Dnsmasq can now synthesise AAAA records for dual-stack
596 hosts which get IPv6 addresses via SLAAC. It is also now
597 possible to use SLAAC and stateless DHCPv6, and to
598 tell clients to use SLAAC addresses as well as DHCP ones.
599 Thanks to Dave Taht for help with this.

604 of relying on clients to send requests with the correct
605 source address, since at least one client in the wild gets

Simon Kelley8643ec72012-03-12 20:04:14 +0000609 Send a preference value of 255 in DHCPv6 replies when
610 --dhcp-authoritative is in effect. This tells clients not
611 to wait around for other DHCP servers.
612
613 Better logging of DHCPv6 options.
614
Simon Kelleye759d422012-03-16 13:18:57 +0000615 Add --host-record. Thanks to Rob Zwissler for the

Simon Kelleya9530962012-03-20 22:07:35 +0000618 Invoke the DHCP script with action "tftp" when a TFTP file
619 transfer completes. The size of the file, address to which
620 it was sent and complete pathname are supplied. Note that
621 version 2.60 introduced some script incompatibilties
622 associated with DHCPv6, and this is a further change. To
623 be safe, scripts should ignore unknown actions, and if
624 not IPv6-aware, should exit if the environment
625 variable DNSMASQ_IAID is set. The use-case for this is
626 to track netboot/install. Suggestion from Shantanu
627 Gadgil.
628
629 Update contrib/port-forward/dnsmasq-portforward to reflect
630 the above.
631
632 Set the environment variable DNSMASQ_LOG_DHCP when running
633 the script id --log-dhcp is in effect, so that script can
Simon Kelley52d4abf2012-03-21 21:39:48 +0000634 taylor their logging verbosity. Suggestion from Malte
635 Forkel.
636
637 Arrange that addresses specified with --listen-address
638 work even if there is no interface carrying the
639 address. This is chiefly useful for IPv4 loopback
640 addresses, where any address in 127.0.0.0/8 is a valid
641 loopback address, but normally only 127.0.0.1 appears on
642 the lo interface. Thanks to Mathieu Trudel-Lapierre for
643 the idea and initial patch.

647 Thanks to Stephane Glondu for the bug report.
648
Simon Kelleyc8257542012-03-28 21:15:41 +0100649 Add a new DHCP lease time keyword, "deprecated" for
650 --dhcp-range. This is only valid for IPv6, and sets the
651 preffered lease time for both DHCP and RA to zero. The
652 effect is that clients can continue to use the address
653 for existing connections, but new connections will use
654 other addresses, if they exist. This makes hitless
655 renumbering at least possible.
656
657 Fix bug in address6_available() which caused DHCPv6 lease

702 Add --dhcp-client-update option.
703
704 Add Lua integration. Dnsmasq can now execute a DHCP
705 lease-change script written in Lua. This needs to be
706 enabled at compile time by setting HAVE_LUASCRIPT in
707 src/config.h or running "make COPTS=-DHAVE_LUASCRIPT"
708 Thanks to Jan-Piet Mens for the idea and proof-of-concept
709 implementation.
710
711 Tidied src/config.h to distinguish between
712 platform-dependent compile-time options which are selected
713 automatically, and builder-selectable compile time

718 confusion. IPPROTO_IP works everywhere now.
719
720 Set TOS on DHCP sockets, this improves things on busy
721 wireless networks. Thanks to Dave Taht for the patch.
722
Simon Kelley984d2fd2012-01-06 14:34:32 +0000723 Determine VERSION automatically based on git magic:
724 release tags or hash values.
Simon Kelleyc72daea2012-01-05 21:33:27 +0000725
Simon Kelleya2761752012-01-18 16:07:21 +0000726 Improve start-up speed when reading large hosts files
727 containing many distinct addresses.
728
729 Fix problem if dnsmasq is started without the stdin,
730 stdout and stderr file descriptors open. This can manifest
731 itself as 100% CPU use. Thanks to Chris Moore for finding
732 this.
733
Simon Kelley9bbc8872012-02-09 21:33:09 +0000734 Fix shell-scripting bug in bld/pkg-wrapper. Thanks to
735 Mark Mitchell for the patch.
736
Simon Kelley751d6f42012-02-10 15:24:51 +0000737 Allow the TFP server or boot server in --pxe-service, to
738 be a domain name instead of an IP address. This allows for
739 round-robin to multiple servers, in the same way as
740 --dhcp-boot. A good suggestion from Cristiano Cumer.
741
Simon Kelleyfdacfb02012-02-28 15:20:25 +0000742 Support BUILDDIR variable in the Makefile. Allows builds
743 for multiple archs from the same source tree with eg.
744 make BUILDDIR=linux (relative to dnsmasq tree)
745 make BUILDDIR=/tmp/openbsd (absolute path)
Simon Kelleye5ffdb92012-02-13 14:19:25 +0000746 If BUILDDIR is not set, compilation happens in the src
Simon Kelleyb36ae192012-02-13 12:54:34 +0000747 directory, as before. Suggestion from Mark Mitchell.
748
Simon Kelleyfdacfb02012-02-28 15:20:25 +0000749 Support DHCPv6. Support is there for the sort of things
750 the existing v4 server does, including tags, options,
751 static addresses and relay support. Missing is prefix
752 delegation, which is probably not required in the dnsmasq
753 niche, and an easy way to accept prefix delegations from
754 an upstream DHCPv6 server, which is. Future plans include
755 support for DHCPv6 router option and MAC address option
756 (to make selecting clients by MAC address work like IPv4).
757 These will be added as the standards mature.
758 This code has been tested, but this is the first release,
759 so don't bet the farm on it just yet. Many thanks to all
760 testers who have got it this far.
Simon Kelley1adadf52012-02-13 22:15:58 +0000761
Simon Kelleyac8540c2012-02-26 20:57:31 +0000762 Support IPv6 router advertisements. This is a
763 simple-minded implementation, aimed at providing the
764 vestigial RA needed to go alongside IPv6. Is picks up
765 configuration from the DHCPv6 conf, and should just need
766 enabling with --enable-ra.
767
Simon Kelley552af8b2012-02-29 20:10:31 +0000768 Fix long-standing wrinkle with --localise-queries that
769 could result in wrong answers when DNS packets arrive
770 via an interface other than the expected one. Thanks to
771 Lorenzo Milesi and John Hanks for spotting this one.
Simon Kelley71ee7ee2012-03-03 18:06:49 +0000772
773 Update French translation. Thanks to Gildas Le Nadan.

Simon Kelleydf66e342012-03-04 20:04:22 +0000775 Update Polish translation. Thanks to Jan Psota.
776
777
Simon Kelleyc72daea2012-01-05 21:33:27 +0000778version 2.59
779 Fix regression in 2.58 which caused failure to start up
780 with some combinations of dnsmasq config and IPv6 kernel
781 network config. Thanks to Brielle Bruns for the bug
782 report.
783
784 Improve dnsmasq's behaviour when network interfaces are
785 still doing duplicate address detection (DAD). Previously,
786 dnsmasq would wait up to 20 seconds at start-up for the
787 DAD state to terminate. This is broken for bridge
788 interfaces on recent Linux kernels, which don't start DAD
789 until the bridge comes up, and so can take arbitrary
790 time. The new behaviour lets dnsmasq poll for an arbitrary
791 time whilst providing service on other interfaces. Thanks
792 to Stephen Hemminger for pointing out the problem.
Simon Kelley74c95c22011-10-19 09:33:39 +0100793
794
Simon Kelley7de060b2011-08-26 17:24:52 +0100795version 2.58
796 Provide a definition of the SA_SIZE macro where it's
797 missing. Fixes build failure on openBSD.
798
799 Don't include a zero terminator at the end of messages
800 sent to /dev/log when /dev/log is a datagram socket.
801 Thanks to Didier Rabound for spotting the problem.
802
803 Add --dhcp-sequential-ip flag, to force allocation of IP
804 addresses in ascending order. Note that the default
805 pseudo-random mode is in general better but some
806 server-deployment applications need this.
807
808 Fix problem where a server-id of 0.0.0.0 is sent to a
809 client when a dhcp-relay is in use if a client renews a
810 lease after dnsmasq restart and before any clients on the
811 subnet get a new lease. Thanks to Mike Ruiz for assistance
812 in chasing this one down.
813
814 Don't return NXDOMAIN to an AAAA query if we have CNAME
815 which points to an A record only: NODATA is the correct
816 reply in this case. Thanks to Tom Fernandes for spotting
817 the problem.
818
819 Relax the need to supply a netmask in --dhcp-range for
820 networks which use a DHCP relay. Whilst this is still
821 desireable, in the absence of a netmask dnsmasq will use
822 a default based on the class (A, B, or C) of the address.
823 This should at least remove a cause of mysterious failure
824 for people using RFC1918 addresses and relays.
825
826 Add support for Linux conntrack connection marking. If
827 enabled with --conntrack, the connection mark for incoming
828 DNS queries will be copied to the outgoing connections
829 used to answer those queries. This allows clever firewall
830 and accounting stuff. Only available if dnsmasq is
831 compiled with HAVE_CONNTRACK and adds a dependency on
832 libnetfilter-conntrack. Thanks to Ed Wildgoose for the
833 initial idea, testing and sponsorship of this function.
834
835 Provide a sane error message when someone attempts to
836 match a tag in --dhcp-host.
837
838 Tweak the behaviour of --domain-needed, to avoid problems
839 with recursive nameservers downstream of dnsmasq. The new
840 behaviour only stops A and AAAA queries, and returns
841 NODATA rather than NXDOMAIN replies.
842
843 Efficiency fix for very large DHCP configurations, thanks
844 to James Gartrell and Mike Ruiz for help with this.
845
846 Allow the TFTP-server address in --dhcp-boot to be a
847 domain-name which is looked up in /etc/hosts. This can
848 give multiple IP addresses which are used round-robin,
849 thus doing TFTP server load-balancing. Thanks to Sushil
850 Agrawal for the patch.
851
852 When two tagged dhcp-options for a particular option
853 number are both valid, use the one which is valid without
854 a tag from the dhcp-range. Allows overriding of the value
855 of a DHCP option for a particular host as well as
856 per-network values. So
857 --dhcp-range=set:interface1,......
858 --dhcp-host=set:myhost,.....
859 --dhcp-option=tag:interface1,option:nis-domain,"domain1"
860 --dhcp-option=tag:myhost,option:nis-domain,"domain2"
861 will set the NIS-domain to domain1 for hosts in the range, but
862 override that to domain2 for a particular host.
863
864 Fix bug which resulted in truncated files and timeouts for
865 some TFTP transfers. The bug only occurs with netascii
866 transfers and needs an unfortunate relationship between
867 file size, blocksize and the number of newlines in the
868 last block before it manifests itself. Many thanks to
869 Alkis Georgopoulos for spotting the problem and providing
870 a comprehensive test-case.
871
872 Fix regression in TFTP server on *BSD platforms introduced
873 in version 2.56, due to confusion with sockaddr
Simon Kelleyde604c12012-10-19 09:50:01 +0100874 length. Many thanks to Loic Pefferkorn for finding this.
Simon Kelley7de060b2011-08-26 17:24:52 +0100875
876 Support scope-ids in IPv6 addresses of nameservers from
877 /etc/resolv.conf and in --server options. Eg
878 nameserver fe80::202:a412:4512:7bbf%eth0 or
879 server=fe80::202:a412:4512:7bbf%eth0. Thanks to
880 Michael Stapelberg for the suggestion.
881
882 Update Polish translation, thanks to Jan Psota.
883
884 Update French translation. Thanks to Gildas Le Nadan.
885
886
Simon Kelley572b41e2011-02-18 18:11:18 +0000887version 2.57
888 Add patches to allow build under Android.
889
890 Provide our own header for the DNS protocol, rather than
891 relying on arpa/nameser.h. This has proved more or less
892 defective over the years and the final straw is that it's
893 effectively empty on Android.
894
895 Fix regression in 2.56 which caused hex constants in
896 configuration to be rejected if they contain the '*'
897 wildcard.
898
899 Correct wrong casts of arguments to ctype.h functions,
900 isdigit(), isxdigit() etc. Thanks to Matthias Andree for
901 spotting this.
902
903 Allow build with IDN support independently from i18n.
904 IDN support continues to be included automatically
905 when i18n is included.
906 'make COPTS=-DHAVE_IDN' is the magic incantation.
907
908 Modify check on extraneous command line junk (added in
909 2.56) so that it doesn't complain about extra _empty_
910 arguments. Otherwise this breaks libvirt.
911
912
Simon Kelley28866e92011-02-14 20:19:14 +0000913version 2.56
914 Add a patch to allow dnsmasq to get interface names right in a
915 Solaris zone. Thanks to Dj Padzensky for this.
916
917 Improve data-type parsing heuristics so that
918 --dhcp-option=option:domain-search,.
919 treats the value as a string and not an IP address.
920 Thanks to Clemens Fischer for spotting that.
921
922 Add IPv6 support to the TFTP server. Many thanks to Jan
923 'RedBully' Seiffert for the patches.
924
925 Log DNS queries at level LOG_INFO, rather then
926 LOG_DEBUG. This makes things consistent with DHCP
927 logging. Thanks to Adam Pribyl for spotting the problem.
928
929 Ensure that dnsmasq terminates cleanly when using
930 --syslog-async even if it cannot make a connection to the
931 syslogd.
932
933 Add --add-mac option. This is to support currently
934 experimental DNS filtering facilities. Thanks to Benjamin
935 Petrin for the orignal patch.
936
937 Fix bug which meant that tags were ignored in dhcp-range
938 configuration specifying PXE-proxy service. Thanks to
939 Cristiano Cumer for spotting this.
940
941 Raise an error if there is extra junk, not part of an
942 option, on the command line.
943
944 Flag a couple of log messages in cache.c as coming from
945 the DHCP subsystem. Thanks to Olaf Westrik for the patch.
946
947 Omit timestamps from logs when a) logging to stderr and
948 b) --keep-in-forground is set. The logging facility on the
949 other end of stderr can be assumned to supply them. Thanks
950 to John Hallam for the patch.
951
952 Don't complain about strings longer than 255 characters in
953 --txt-record, just split the long strings into 255
954 character chunks instead.
955
956 Fix crash on double-free. This bug can only happen when
957 dhcp-script is in use and then only in rare circumstances
958 triggered by high DHCP transaction rate and a slow
959 script. Thanks to Ferenc Wagner for finding the problem.
960
961 Only log that a file has been sent by TFTP after the
962 transfer has completed succesfully.
963
964 A good suggestion from Ferenc Wagner: extend
965 the --domain option to allow this sort of thing:
966 --domain=thekelleys.org.uk,192.168.0.0/24,local
967 which automatically creates
968 --local=/thekelleys.org.uk/
969 --local=/0.168.192.in-addr.arpa/
970
971 Tighten up syntax checking of hex contants in the config
972 file. Thanks to Fred Damen for spotting this.
973
974 Add dnsmasq logo/icon, contributed by Justin Swift. Many
975 thanks for that.
976
977 Never cache DNS replies which have the 'cd' bit set, or
978 which result from queries forwarded with the 'cd' bit
979 set. The 'cd' bit instructs a DNSSEC validating server
980 upstream to ignore signature failures and return replies
981 anyway. Without this change it's possible to pollute the
982 dnsmasq cache with bad data by making a query with the
983 'cd' bit set and subsequent queries would return this data
984 without its being marked as suspect. Thanks to Anders
985 Kaseorg for pointing out this problem.
986
987 Add --proxy-dnssec flag, for compliance with RFC
988 4035. Dnsmasq will now clear the 'ad' bit in answers returned
989 from upstream validating nameservers unless this option is
990 set.
991
992 Allow a filename of "-" for --conf-file to read
993 stdin. Suggestion from Timothy Redaelli.
994
995 Rotate the order of SRV records in replies, to provide
996 round-robin load balancing when all the priorities are
997 equal. Thanks to Peter McKinney for the suggestion.
998
999 Edit
1000 contrib/MacOSX-launchd/uk.org.thekelleys.dnsmasq.plist
1001 so that it doesn't log all queries to a file by
1002 default. Thanks again to Peter McKinney.
1003
1004 By default, setting an IPv4 address for a domain but not
1005 an IPv6 address causes dnsmasq to return
1006 an NODATA reply for IPv6 (or vice-versa). So
1007 --address=/google.com/1.2.3.4 stops IPv6 queries for
1008 *google.com from being forwarded. Make it possible to
1009 override this behaviour by defining the sematics if the
1010 same domain appears in both --server and --address.
1011 In that case, the --address has priority for the address
1012 family in which is appears, but the --server has priority
1013 of the address family which doesn't appear in --adddress
1014 So:
1015 --address=/google.com/1.2.3.4
1016 --server=/google.com/#
1017 will return 1.2.3.4 for IPv4 queries for *.google.com but
1018 forward IPv6 queries to the normal upstream nameserver.
1019 Similarly when setting an IPv6 address
1020 only this will allow forwarding of IPv4 queries. Thanks to
1021 William for pointing out the need for this.
1022
1023 Allow more than one --dhcp-optsfile and --dhcp-hostsfile
1024 and make them understand directories as arguments in the
1025 same way as --addn-hosts. Suggestion from John Hanks.
1026
1027 Ignore rebinding requests for leases we don't know
1028 about. Rebind is broadcast, so we might get to overhear a
1029 request meant for another DHCP server. NAKing this is
1030 wrong. Thanks to Brad D'Hondt for assistance with this.
1031
Simon Kelley572b41e2011-02-18 18:11:18 +00001032 Fix cosmetic bug which produced strange output when

1054 Fix failure to compile on Debian/kFreeBSD. Thanks to
1055 Axel Beckert and Petr Salinger.
1056
1057 Fix code to avoid scary strict-aliasing warnings
1058 generated by gcc 4.4.
1059
1060 Added FAQ entry warning about DHCP failures with Vista
1061 when firewalls block 255.255.255.255.
1062
1063 Fixed bug which caused bad things to happen if a
1064 resolv.conf file which exists is subsequently removed.
1065 Thanks to Nikolai Saoukh for the patch.
1066
1067 Rationalised the DHCP tag system. Every configuration item
1068 which can set a tag does so by adding "set:<tag>" and
1069 every configuration item which is conditional on a tag is
1070 made so by "tag:<tag>". The NOT operator changes to '!',
1071 which is a bit more intuitive too. Dhcp-host directives
1072 can set more than one tag now. The old '#' NOT,
1073 "net:" prefix and no-prefixes are still honoured, so
1074 no existing config file needs to be changed, but
1075 the documentation and new-style config files should be
1076 much less confusing.
1077
1078 Added --tag-if to allow boolean operations on tags.
1079 This allows complicated logic to be clearer and more
1080 general. A great suggestion from Richard Voigt.
1081
1082 Add broadcast/unicast information to DHCP logging.
1083
1084 Allow --dhcp-broadcast to be unconditional.
1085
1086 Fixed incorrect behaviour with NOT <tag> conditionals in
1087 dhcp-options. Thanks to Max Turkewitz for assistance
1088 finding this.
1089
1090 If we send vendor-class encapsulated options based on the
1091 vendor-class supplied by the client, and no explicit
1092 vendor-class option is given, echo back the vendor-class
1093 from the client.
1094
1095 Fix bug which stopped dnsmasq from matching both a
1096 circuitid and a remoteid. Thanks to Ignacio Bravo for
1097 finding this.
1098
1099 Add --dhcp-proxy, which makes it possible to configure
1100 dnsmasq to use a DHCP relay agent as a full proxy, with
1101 all DHCP messages passing through the proxy. This is
1102 useful if the relay adds extra information to the packets
1103 it forwards, but cannot be configured with the RFC 5107
1104 server-override option.
1105
1106 Added interface:<iface name> part to dhcp-range. The
1107 semantics of this are very odd at first sight, but it
1108 allows a single line of the form
1109 dhcp-range=interface:virt0,192.168.0.4,192.168.0.200
1110 to be added to dnsmasq configuration which then supplies
1111 DHCP and DNS services to that interface, without affecting
1112 what services are supplied to other interfaces and
1113 irrespective of the existance or lack of
1114 interface=<interface>
1115 lines elsewhere in the dnsmasq configuration. The idea is
1116 that such a line can be added automatically by libvirt
1117 or equivalent systems, without disturbing any manual
1118 configuration.
1119
1120 Similarly to the above, allow --enable-tftp=<interface>
1121
1122 Allow a TFTP root to be set separately for requests via
1123 different interfaces, --tftp-root=<path>,<interface>
1124
1125 Correctly handle and log clashes between CNAMES and
1126 DNS names being given to DHCP leases. This fixes a bug
1127 which caused nonsense IP addresses to be logged. Thanks to
1128 Sergei Zhirikov for finding and analysing the problem.
1129
1130 Tweak flush_log so as to avoid leaving the log
1131 file in non-blocking mode. O_NONBLOCK is a property of the
1132 file, not the process/descriptor.
1133
1134 Fix contrib/Solaris10/create_package
1135 (/usr/man -> /usr/share/man) Thanks to Vita Batrla.
1136
1137 Fix a problem where, if a client got a lease, then went
1138 to another subnet and got another lease, then moved back,
1139 it couldn't resume the old lease, but would instead get
1140 a new address. Thanks to Leonardo Rodrigues for spotting
1141 this and testing the fix.
1142
1143 Fix weird bug which sometimes omitted certain characters
1144 from the start of quoted strings in dhcp-options. Thanks
1145 to Dayton Turner for spotting the problem.
1146
1147 Add facility to redirect some domains to the standard
1148 upstream servers: this allows something like
1149 --server=/google.com/1.2.3.4 --server=/www.google.com/#
1150 which will send queries for *.google.com to 1.2.3.4,
1151 except *www.google.com which will be forwarded as usual.
1152 Thanks to AJ Weber for prompting this addition.
1153
1154 Improve the hash-algorithm used to generate IP addresses
1155 from MAC addresses during initial DHCP address
1156 allocation. This improves performance when large numbers
1157 of hosts with similar MAC addresses all try and get an IP
1158 address at the same time. Thanks to Paul Smith for his
1159 work on this.
1160
1161 Tweak DHCP code so that --bridge-interface can be used to
1162 select which IP alias of an interface should be used for
1163 DHCP purposes on Linux. If eth0 has an alias eth0:dhcp
1164 then adding --bridge-interface=eth0:dhcp,eth0 will use
1165 the address of eth0:dhcp to determine the correct subnet
1166 for DHCP address allocation. Thanks to Pawel Golaszewski
1167 for prompting this and Eric Cooper for further testing.
1168
1169 Add --dhcp-generate-names. Suggestion by Ferenc Wagner.
1170
1171 Tweak DNS server selection algorithm when there is more
1172 than one server available for a domain, eg.
1173 --server=/mydomain/1.1.1.1
1174 --server=/mydomain/2.2.2.2
1175 Thanks to Alberto Cuesta-Canada for spotting a weakness
1176 here.
1177
1178 Add --max-ttl. Thanks to Fredrik Ringertz for the patch.
1179
1180 Allow --log-facility=- to force all logging to
1181 stderr. Suggestion from Clemens Fischer.
1182
1183 Fix regression which caused configuration like
1184 --address=/.domain.com/1.2.3.4 to be rejected. The dot to the
1185 left of the domain has been implied and not required for a
1186 long time, but it should be accepted for backward
1187 compatibility. Thanks to Andrew Burcin for spotting this.
1188
1189 Add --rebind-domain-ok and --rebind-localhost-ok.
1190 Suggestion from Clemens Fischer.
1191
1192 Log replies to queries of type TXT, when --log-queries
1193 is set.
1194
1195 Fix compiler warnings when compiled with -DNO_DHCP. Thanks
1196 to Shantanu Gadgil for the patch.
1197
1198 Updated French translation. Thanks to Gildas Le Nadan.
1199
1200 Updated Polish translation. Thanks to Jan Psota.
1201
1202 Updated German translation. Thanks to Matthias Andree.
1203
1204 Added contrib/static-arp, thanks to Darren Hoo.
1205
1206 Fix corruption of the domain when a name from /etc/hosts
1207 overrides one supplied by a DHCP client. Thanks to Fedor
1208 Kozhevnikov for spotting the problem.
1209
1210 Updated Spanish translation. Thanks to Chris Chatham.

Simon Kelley316e2732010-01-22 20:16:09 +00001213version 2.52
1214 Work around a Linux kernel bug which insists that the
1215 length of the option passed to setsockopt must be at least
1216 sizeof(int) bytes, even if we're calling SO_BINDTODEVICE
1217 and the device name is "lo". Note that this is fixed
1218 in kernel 2.6.31, but the workaround is harmless and
1219 allows earlier kernels to be used. Also fix dnsmasq
1220 bug which reported the wrong address when this failed.
1221 Thanks to Fedor for finding this.
1222
1223 The API for IPv6 PKTINFO changed around Linux kernel
1224 2.6.14. Workaround the case where dnsmasq is compiled
1225 against newer headers, but then run on an old kernel:
1226 necessary for some *WRT distros.
1227
1228 Re-read the set of network interfaces when re-loading
1229 /etc/resolv.conf if --bind-interfaces is not set. This
1230 handles the case that loopback interfaces do not exist
1231 when dnsmasq is first started.
1232
1233 Tweak the PXE code to support port 4011. This should
1234 reduce broadcasts and make things more reliable when other
1235 servers are around. It also improves inter-operability
1236 with certain clients.
1237
1238 Make a pxe-service configuration with no filename or boot
1239 service type legal: this does a local boot. eg.
1240 pxe-service=x86PC, "Local boot"
1241
1242 Be more conservative in detecting "A for A"
1243 queries. Dnsmasq checks if the name in a type=A query looks
1244 like a dotted-quad IP address and answers the query itself
1245 if so, rather than forwarding it. Previously dnsmasq
1246 relied in the library function inet_addr() to convert
1247 addresses, and that will accept some things which are
1248 confusing in this context, like 1.2.3 or even just
1249 1234. Now we only do A for A processing for four decimal
1250 numbers delimited by dots.
1251
1252 A couple of tweaks to fix compilation on Solaris. Thanks
1253 to Joel Macklow for help with this.
1254
1255 Another Solaris compilation tweak, needed for Solaris
1256 2009.06. Thanks to Lee Essen for that.
1257
1258 Added extract packaging stuff from Lee Essen to
1259 contrib/Solaris10.
1260
1261 Increased the default limit on number of leases to 1000
1262 (from 150). This is mainly a defence against DoS attacks,
1263 and for the average "one for two class C networks"
1264 installation, IP address exhaustion does that just as
1265 well. Making the limit greater than the number of IP
1266 addresses available in such an installation removes a
1267 surprise which otherwise can catch people out.
1268
1269 Removed extraneous trailing space in the value of the
1270 DNSMASQ_TIME_REMAINING DNSMASQ_LEASE_LENGTH and
1271 DNSMASQ_LEASE_EXPIRES environment variables. Thanks to
1272 Gildas Le Nadan for spotting this.
1273
1274 Provide the network-id tags for a DHCP transaction to
1275 the lease-change script in the environment variable
1276 DNSMASQ_TAGS. A good suggestion from Gildas Le Nadan.
1277
1278 Add support for RFC3925 "Vendor-Identifying Vendor
1279 Options". The syntax looks like this:
1280 --dhcp-option=vi-encap:<enterprise number>, .........
1281
1282 Add support to --dhcp-match to allow matching against
1283 RFC3925 "Vendor-Identifying Vendor Classes". The syntax
1284 looks like this:
1285 --dhcp-match=tag,vi-encap<enterprise number>, <value>
1286
1287 Add some application specific code to assist in
1288 implementing the Broadband forum TR069 CPE-WAN
1289 specification. The details are in contrib/CPE-WAN/README
1290
1291 Increase the default DNS packet size limit to 4096, as
1292 recommended by RFC5625 section 4.4.3. This can be
1293 reconfigured using --edns-packet-max if needed. Thanks to
1294 Francis Dupont for pointing this out.
1295
Simon Kelley8ef5ada2010-06-03 19:42:45 +01001296 Rewrite query-ids even for TSIG signed packets, since
Simon Kelley316e2732010-01-22 20:16:09 +00001297 this is allowed by RFC5625 section 4.5.
1298
1299 Use getopt_long by default on OS X. It has been supported
1300 since version 10.3.0. Thanks to Arek Dreyer for spotting
1301 this.
1302
1303 Added up-to-date startup configuration for MacOSX/launchd
1304 in contrib/MacOSX-launchd. Thanks to Arek Dreyer for
1305 providing this.
1306
1307 Fix link error when including Dbus but excluding DHCP.
1308 Thanks to Oschtan for the bug report.
1309
1310 Updated French translation. Thanks to Gildas Le Nadan.
1311
1312 Updated Polish translation. Thanks to Jan Psota.
1313
1314 Updated Spanish translation. Thanks to Chris Chatham.
1315
Simon Kelley8ef5ada2010-06-03 19:42:45 +01001316 Fixed confusion about domains, when looking up DHCP hosts
1317 in /etc/hosts. This could cause spurious "Ignoring
1318 domain..." messages. Thanks to Fedor Kozhevnikov for
1319 finding and analysing the problem.
Simon Kelley316e2732010-01-22 20:16:09 +00001320
Simon Kelley8ef5ada2010-06-03 19:42:45 +01001321
Simon Kelley1f15b812009-10-13 17:49:32 +01001322version 2.51
1323 Add support for internationalised DNS. Non-ASCII characters
1324 in domain names found in /etc/hosts, /etc/ethers and
1325 /etc/dnsmasq.conf will be correctly handled by translation to
1326 punycode, as specified in RFC3490. This function is only
1327 available if dnsmasq is compiled with internationalisation
1328 support, and adds a dependency on GNU libidn. Without i18n
1329 support, dnsmasq continues to be compilable with just
1330 standard tools. Thanks to Yves Dorfsman for the
1331 suggestion.
1332
1333 Add two more environment variables for lease-change scripts:
1334 First, DNSMASQ_SUPPLIED_HOSTNAME; this is set to the hostname
1335 supplied by a client, even if the actual hostname used is
1336 over-ridden by dhcp-host or dhcp-ignore-names directives.
1337 Also DNSMASQ_RELAY_ADDRESS which gives the address of
1338 a DHCP relay, if used.
1339 Suggestions from Michael Rack.
1340
1341 Fix regression which broke echo of relay-agent
1342 options. Thanks to Michael Rack for spotting this.
1343
1344 Don't treat option 67 as being interchangeable with
1345 dhcp-boot parameters if it's specified as
1346 dhcp-option-force.
1347
1348 Make the code to call scripts on lease-change compile-time
1349 optional. It can be switched off by editing src/config.h
1350 or building with "make COPTS=-DNO_SCRIPT".
1351
1352 Make the TFTP server cope with filenames from Windows/DOS
1353 which use '\' as pathname separator. Thanks to Ralf for
1354 the patch.
1355
1356 Updated Polish translation. Thanks to Jan Psota.
1357
1358 Warn if an IP address is duplicated in /etc/ethers. Thanks
1359 to Felix Schwarz for pointing this out.
1360
1361 Teach --conf-dir to take an option list of file suffices
1362 which will be ignored when scanning the directory. Useful
1363 for backup files etc. Thanks to Helmut Hullen for the
1364 suggestion.
1365
1366 Add new DHCP option named tftpserver-address, which
1367 corresponds to the third argument of dhcp-boot. This
1368 allows the complete functionality of dhcp-boot to be
1369 replicated with dhcp-option. Useful when using
1370 dhcp-optsfile.
1371
1372 Test which upstream nameserver to use every 10 seconds
1373 or 50 queries and not just when a query times out and
1374 is retried. This should improve performance when there
1375 is a slow nameserver in the list. Thanks to Joe for the
1376 suggestion.
1377
1378 Don't do any PXE processing, even for clients with the
1379 correct vendorclass, unless at least one pxe-prompt or
1380 pxe-service option is given. This stops dnsmasq
1381 interfering with proxy PXE subsystems when it is just
1382 the DHCP server. Thanks to Spencer Clark for spotting this.
1383
1384 Limit the blocksize used for TFTP transfers to a value
1385 which avoids packet fragmentation, based on the MTU of the
1386 local interface. Many netboot ROMs can't cope with
1387 fragmented packets.
1388
1389 Honour dhcp-ignore configuration for PXE and proxy-PXE
1390 requests. Thanks to Niels Basjes for the bug report.
1391
1392 Updated French translation. Thanks to Gildas Le Nadan.

Simon Kelley1f15b812009-10-13 17:49:32 +01001396 Fix security problem which allowed any host permitted to
Simon Kelley77e94da2009-08-31 17:32:17 +01001397 do TFTP to possibly compromise dnsmasq by remote buffer
1398 overflow when TFTP enabled. Thanks to Core Security
1399 Technologies and Iván Arce, Pablo Hernán Jorge, Alejandro
1400 Pablo Rodriguez, Martín Coco, Alberto Soliño Testa and
1401 Pablo Annetta. This problem has Bugtraq id: 36121
1402 and CVE: 2009-2957
1403
1404 Fix a problem which allowed a malicious TFTP client to
1405 crash dnsmasq. Thanks to Steve Grubb at Red Hat for
1406 spotting this. This problem has Bugtraq id: 36120 and
1407 CVE: 2009-2958

1411 Fix regression in 2.48 which disables the lease-change
1412 script. Thanks to Jose Luis Duran for spotting this.
1413
1414 Log TFTP "file not found" errors. These were not logged,
1415 since a normal PXELinux boot generates many of them, but
1416 the lack of the messages seems to be more confusing than
1417 routinely seeing them when there is no real error.
1418
1419 Update Spanish translation. Thanks to Chris Chatham.

Simon Kelley7622fc02009-06-04 20:32:05 +01001422version 2.48
1423 Archived the extensive, backwards, changelog to
1424 CHANGELOG.archive. The current changelog now runs from
1425 version 2.43 and runs conventionally.
Simon Kelley9e4abcb2004-01-22 19:47:41 +00001426
Simon Kelley7622fc02009-06-04 20:32:05 +01001427 Fixed bug which broke binding of servers to physical
1428 interfaces when interface names were longer than four
1429 characters. Thanks to MURASE Katsunori for the patch.
Simon Kelley9e4abcb2004-01-22 19:47:41 +00001430
Simon Kelley7622fc02009-06-04 20:32:05 +01001431 Fixed netlink code to check that messages come from the
1432 correct source, and not another userspace process. Thanks
1433 to Steve Grubb for the patch.
Simon Kelley9e4abcb2004-01-22 19:47:41 +00001434
Simon Kelley7622fc02009-06-04 20:32:05 +01001435 Maintainability drive: removed bug and missing feature
1436 workarounds for some old platforms. Solaris 9, OpenBSD
1437 older than 4.1, Glibc older than 2.2, Linux 2.2.x and
1438 DBus older than 1.1.x are no longer supported.
Simon Kelley9e4abcb2004-01-22 19:47:41 +00001439
Simon Kelley7622fc02009-06-04 20:32:05 +01001440 Don't read included configuration files more than once:
1441 allows complex configuration structures without problems.
Simon Kelley9e4abcb2004-01-22 19:47:41 +00001442
Simon Kelley7622fc02009-06-04 20:32:05 +01001443 Mark log messages from the various subsystems in dnsmasq:
1444 messages from the DHCP subsystem now have the ident string
1445 "dnsmasq-dhcp" and messages from TFTP have ident
1446 "dnsmasq-tftp". Thanks to Olaf Westrik for the patch.
Simon Kelley9e4abcb2004-01-22 19:47:41 +00001447
Simon Kelley7622fc02009-06-04 20:32:05 +01001448 Fix possible infinite DHCP protocol loop when an IP
1449 address nailed to a hostname (not a MAC address) and a
1450 host sometimes provides the name, sometimes not.
Simon Kelley9e4abcb2004-01-22 19:47:41 +00001451
Simon Kelley7622fc02009-06-04 20:32:05 +01001452 Allow --addn-hosts to take a directory: all the files
1453 in the directory are read. Thanks to Phil Cornelius for
1454 the suggestion.
Simon Kelley9e4abcb2004-01-22 19:47:41 +00001455
Simon Kelley7622fc02009-06-04 20:32:05 +01001456 Support --bridge-interface on all platforms, not just BSD.
Simon Kelley1ab84e22004-01-29 16:48:35 +00001457
Simon Kelley7622fc02009-06-04 20:32:05 +01001458 Added support for advanced PXE functions. It's now
1459 possible to define a prompt and menu options which will
1460 be displayed when a client PXE boots. It's also possible to
1461 hand-off booting to other boot servers. Proxy-DHCP, where
1462 dnsmasq just supplies the PXE information and another DHCP
1463 server does address allocation, is also allowed. See the
1464 --pxe-prompt and --pxe-service keywords. Thanks to
1465 Alkis Georgopoulos for the suggestion and Guilherme Moro
1466 and Michael Brown for assistance.
Simon Kelley1ab84e22004-01-29 16:48:35 +00001467
Simon Kelley7622fc02009-06-04 20:32:05 +01001468 Improvements to DHCP logging. Thanks to Tom Metro for
1469 useful suggestions.
1470
1471 Add ability to build dnsmasq without DHCP support. To do
1472 this, edit src/config.h or build with
1473 "make COPTS=-DNO_DHCP". Thanks to Mahavir Jain for the patch.
1474
1475 Added --test command-line switch - syntax check
1476 configuration files only.

1482 Updated French translation. Thanks to Gildas Le Nadan.
1483
1484 Fixed interface enumeration code to work on NetBSD
1485 5.0. Thanks to Roy Marples for the patch.
1486
1487 Updated config.h to use the same location for the lease
1488 file on NetBSD as the other *BSD variants. Also allow
1489 LEASEFILE and CONFFILE symbols to be overriden in CFLAGS.
1490
1491 Handle duplicate address detection on IPv6 more
1492 intelligently. In IPv6, an interface can have an address
1493 which is not usable, because it is still undergoing DAD
1494 (such addresses are marked "tentative"). Attempting to
1495 bind to an address in this state returns an error,
1496 EADDRNOTAVAIL. Previously, on getting such an error,
1497 dnsmasq would silently abandon the address, and never
1498 listen on it. Now, it retries once per second for 20
1499 seconds before generating a fatal error. 20 seconds should
1500 be long enough for any DAD process to complete, but can be
1501 adjusted in src/config.h if necessary. Thanks to Martin
1502 Krafft for the bug report.
1503
1504 Add DBus introspection. Patch from Jeremy Laine.
1505
1506 Update Dbus configuration file. Patch from Colin Walters.
1507 Fix for this bug:
1508 http://bugs.freedesktop.org/show_bug.cgi?id=18961
1509
1510 Support arbitrarily encapsulated DHCP options, suggestion
1511 and initial patch from Samium Gromoff. This is useful for
1512 (eg) gPXE, which expect all its private options to be
1513 encapsulated inside a single option 175. So, eg,
1514
1515 dhcp-option = encap:175, 190, "iscsi-client0"
1516 dhcp-option = encap:175, 191, "iscsi-client0-secret"
1517
1518 will provide iSCSI parameters to gPXE.
1519
1520 Enhance --dhcp-match to allow testing of the contents of a
1521 client-sent option, as well as its presence. This
1522 application in mind for this is RFC 4578
1523 client-architecture specifiers, but it's generally useful.
1524 Joey Korkames suggested the enhancement.
1525
1526 Move from using the IP_XMIT_IF ioctl to IP_BOUND_IF on
1527 OpenSolaris. Thanks to Bastian Machek for the heads-up.
1528
1529 No longer complain about blank lines in
1530 /etc/ethers. Thanks to Jon Nelson for the patch.
1531
1532 Fix binding of servers to physical devices, eg
1533 --server=/domain/1.2.3.4@eth0 which was broken from 2.43
1534 onwards unless --query-port=0 set. Thanks to Peter Naulls
1535 for the bug report.
1536
1537 Reply to DHCPINFORM requests even when the supplied ciaddr
1538 doesn't fall in any dhcp-range. In this case it's not
1539 possible to supply a complete configuration, but
1540 individually-configured options (eg PAC) may be useful.
1541
1542 Allow the source address of an alias to be a range:
1543 --alias=192.168.0.0,10.0.0.0,255.255.255.0 maps the whole
1544 subnet 192.168.0.0->192.168.0.255 to 10.0.0.0->10.0.0.255,
1545 as before.
1546 --alias=192.168.0.10-192.168.0.40,10.0.0.0,255.255.255.0
1547 maps only the 192.168.0.10->192.168.0.40 region. Thanks to
1548 Ib Uhrskov for the suggestion.
1549
1550 Don't dynamically allocate DHCP addresses which may break
1551 Windows. Addresses which end in .255 or .0 are broken in
1552 Windows even when using supernetting.
1553 --dhcp-range=192.168.0.1,192.168.1.254,255,255,254.0 means
1554 192.168.0.255 is a valid IP address, but not for Windows.
1555 See Microsoft KB281579. We therefore no longer allocate
1556 these addresses to avoid hard-to-diagnose problems.
1557
1558 Update Polish translation. Thanks to Jan Psota.
1559
1560 Delete the PID-file when dnsmasq shuts down. Note that by
1561 this time, dnsmasq is normally not running as root, so
1562 this will fail if the PID-file is stored in a root-owned
1563 directory; such failure is silently ignored. To take
1564 advantage of this feature, the PID-file must be stored in a
1565 directory owned and write-able by the user running
1566 dnsmasq.

1570 Allow --bootp-dynamic to take a netid tag, so that it may
1571 be selectively enabled. Thanks to Olaf Westrik for the
1572 suggestion.
1573
1574 Remove ISC-leasefile reading code. This has been
1575 deprecated for a long time, and last time I removed it, it
1576 ended up going back by request of one user. This time,
1577 it's gone for good; otherwise it would need to be
1578 re-worked to support multiple domains (see below).
1579
1580 Support DHCP clients in multiple DNS domains. This is a
1581 long-standing request. Clients are assigned to a domain
1582 based in their IP address.
1583
1584 Add --dhcp-fqdn flag, which changes behaviour if DNS names
1585 assigned to DHCP clients. When this is set, there must be
1586 a domain associated with each client, and only
1587 fully-qualified domain names are added to the DNS. The
1588 advantage is that the only the FQDN needs to be unique,
1589 so that two or more DHCP clients can share a hostname, as
1590 long as they are in different domains.
1591
1592 Set environment variable DNSMASQ_DOMAIN when invoking
1593 lease-change script. This may be useful information to
1594 have now that it's variable.
1595
1596 Tighten up data-checking code for DNS packet
1597 handling. Thanks to Steve Dodd who found certain illegal
1598 packets which could crash dnsmasq. No memory overwrite was
1599 possible, so this is not a security issue beyond the DoS
1600 potential.
1601
1602 Update example config dhcp option 47, the previous
1603 suggestion generated an illegal, zero-length,
1604 option. Thanks to Matthias Andree for finding this.
1605
1606 Rewrite hosts-file reading code to remove the limit of
1607 1024 characters per line. John C Meuser found this.
1608
1609 Create a net-id tag with the name of the interface on
1610 which the DHCP request was received.
1611
1612 Fixed minor memory leak in DBus code, thanks to Jeremy
1613 Laine for the patch.
1614
1615 Emit DBus signals as the DHCP lease database
1616 changes. Thanks to Jeremy Laine for the patch.
1617
1618 Allow for more that one MAC address in a dhcp-host
1619 line. This configuration tells dnsmasq that it's OK to
1620 abandon a DHCP lease of the fixed address to one MAC
1621 address, if another MAC address in the dhcp-host statement
1622 asks for an address. This is useful to give a fixed
1623 address to a host which has two network interfaces
1624 (say, a laptop with wired and wireless interfaces.)
1625 It's very important to ensure that only one interface
1626 at a time is up, since dnsmasq abandons the first lease
1627 and re-uses the address before the leased time has
1628 elapsed. John Gray suggested this.
1629
1630 Tweak the response to a DHCP request packet with a wrong
1631 server-id when --dhcp-authoritative is set; dnsmasq now
1632 returns a DHCPNAK, rather than silently ignoring the
1633 packet. Thanks to Chris Marget for spotting this
1634 improvement.
1635
1636 Add --cname option. This provides a limited alias
1637 function, usable for DHCP names. Thanks to AJ Weber for
1638 suggestions on this.
1639
1640 Updated contrib/webmin with latest version from Neil
1641 Fisher.
1642
1643 Updated Polish translation. Thanks to Jan Psota.
1644
1645 Correct the text names for DHCP options 64 and 65 to be
1646 "nis+-domain" and "nis+-servers".
1647
1648 Updated Spanish translation. Thanks to Chris Chatham.
1649
1650 Force re-reading of /etc/resolv.conf when an "interface
1651 up" event occurs.
1652
1653
1654version 2.45
1655 Fix total DNS failure in release 2.44 unless --min-port
1656 specified. Thanks to Steven Barth and Grant Coady for
1657 bugreport. Also reject out-of-range port spec, which could
1658 break things too: suggestion from Gilles Espinasse.
1659
1660
1661version 2.44
1662 Fix crash when unknown client attempts to renew a DHCP
1663 lease, problem introduced in version 2.43. Thanks to
1664 Carlos Carvalho for help chasing this down.
1665
1666 Fix potential crash when a host which doesn't have a lease
1667 does DHCPINFORM. Again introduced in 2.43. This bug has
1668 never been reported in the wild.
1669
1670 Fix crash in netlink code introduced in 2.43. Thanks to
1671 Jean Wolter for finding this.
1672
1673 Change implementation of min_port to work even if min-port
1674 is large.
1675
1676 Patch to enable compilation of latest Mac OS X. Thanks to
1677 David Gilman.
1678
1679 Update Spanish translation. Thanks to Christopher Chatham.
1680
1681
1682version 2.43
1683 Updated Polish translation. Thanks to Jan Psota.
1684
1685 Flag errors when configuration options are repeated
1686 illegally.
1687
1688 Further tweaks for GNU/kFreeBSD
1689
1690 Add --no-wrap to msgmerge call - provides nicer .po file
1691 format.
1692
1693 Honour lease-time spec in dhcp-host lines even for
1694 BOOTP. The user is assumed to known what they are doing in
1695 this case. (Hosts without the time spec still get infinite
1696 leases for BOOTP, over-riding the default in the
1697 dhcp-range.) Thanks to Peter Katzmann for uncovering this.
1698
1699 Fix problem matching relay-agent ids. Thanks to Michael
1700 Rack for the bug report.
1701
1702 Add --naptr-record option. Suggestion from Johan
1703 Bergquist.
1704
1705 Implement RFC 5107 server-id-override DHCP relay agent
1706 option.
1707
1708 Apply patches from Stefan Kruger for compilation on
1709 Solaris 10 under Sun studio.
1710
1711 Yet more tweaking of Linux capability code, to suppress
1712 pointless wingeing from kernel 2.6.25 and above.
1713
1714 Improve error checking during startup. Previously, some
1715 errors which occurred during startup would be worked
1716 around, with dnsmasq still starting up. Some were logged,
1717 some silent. Now, they all cause a fatal error and dnsmasq
1718 terminates with a non-zero exit code. The errors are those
1719 associated with changing uid and gid, setting process
1720 capabilities and writing the pidfile. Thanks to Uwe
1721 Gansert and the Suse security team for pointing out
1722 this improvement, and Bill Reimers for good implementation
1723 suggestions.
1724
1725 Provide NO_LARGEFILE compile option to switch off largefile
1726 support when compiling against versions of uclibc which
1727 don't support it. Thanks to Stephane Billiart for the patch.
1728
1729 Implement random source ports for interactions with
1730 upstream nameservers. New spoofing attacks have been found
1731 against nameservers which do not do this, though it is not
1732 clear if dnsmasq is vulnerable, since to doesn't implement
1733 recursion. By default dnsmasq will now use a different
1734 source port (and socket) for each query it sends
1735 upstream. This behaviour can suppressed using the
1736 --query-port option, and the old default behaviour
1737 restored using --query-port=0. Explicit source-port
1738 specifications in --server configs are still honoured.
1739
1740 Replace the random number generator, for better
1741 security. On most BSD systems, dnsmasq uses the
1742 arc4random() RNG, which is secure, but on other platforms,
1743 it relied on the C-library RNG, which may be
1744 guessable and therefore allow spoofing. This release
1745 replaces the libc RNG with the SURF RNG, from Daniel
1746 J. Berstein's DJBDNS package.
1747
1748 Don't attempt to change user or group or set capabilities
1749 if dnsmasq is run as a non-root user. Without this, the
1750 change from soft to hard errors when these fail causes
1751 problems for non-root daemons listening on high
1752 ports. Thanks to Patrick McLean for spotting this.
1753
1754 Updated French translation. Thanks to Gildas Le Nadan.
