Simon Kelley00cd9d52014-10-02 21:44:21 +01001version 2.73
2 Fix crash at startup when an empty suffix is supplied to
3 --conf-dir, also trivial memory leak. Thanks to
4 Tomas Hozza for spotting this.
Simon Kelley800c5cc2014-12-15 17:50:15 +00005
6 Remove floor of 4096 on advertised EDNS0 packet size when
7 DNSSEC in use, the original rationale for this has long gone.
8 Thanks to Anders Kaseorg for spotting this.

Simon Kelleyad946d52014-12-15 17:52:22 +000010 Use inotify for checking on updates to /etc/resolv.conf and
11 friends under Linux. This fixes race conditions when the files are
Simon Kelley04918052015-01-26 11:23:43 +000012 updated rapidly and saves CPU by noy polling. To build
13 a binary that runs on old Linux kernels without inotify,
14 use make COPTS=-DNO_INOTIFY
Simon Kelley3ad3f3b2014-12-16 18:25:17 +000015
16 Fix breakage of --domain=<domain>,<subnet>,local - only reverse
17 queries were intercepted. THis appears to have been broken
18 since 2.69. Thanks to Josh Stone for finding the bug.
Simon Kelley47669362014-12-17 12:41:56 +000019
20 Eliminate IPv6 privacy addresses and deprecated addresses from
21 the answers given by --interface-name. Note that reverse queries
22 (ie looking for names, given addresses) are not affected.
23 Thanks to Michael Gorbach for the suggestion.
Simon Kelley094b5c32014-12-21 16:11:52 +000024
25 Fix crash in DNSSEC code with long RRs. Thanks to Marco Davids
26 for the bug report.
Glen Huang32fc6db2014-12-27 15:28:12 +000027
28 Add --ignore-address option. Ignore replies to A-record
29 queries which include the specified address. No error is
30 generated, dnsmasq simply continues to listen for another
31 reply. This is useful to defeat blocking strategies which
32 rely on quickly supplying a forged answer to a DNS
33 request for certain domains, before the correct answer can
34 arrive. Thanks to Glen Huang for the patch.
Simon Kelleyad946d52014-12-15 17:52:22 +000035
Simon Kelley97e618a2015-01-07 21:55:43 +000036 Revisit the part of DNSSEC validation which determines if an
37 unsigned answer is legit, or is in some part of the DNS
38 tree which should be signed. Dnsmasq now works from the
39 DNS root downward looking for the limit of signed
40 delegations, rather than working bottom up. This is
41 both more correct, and less likely to trip over broken
42 nameservers in the unsigned parts of the DNS tree
43 which don't respond well to DNSSEC queries.
Simon Kelley00cd9d52014-10-02 21:44:21 +010044
Simon Kelley25cf5e32015-01-09 15:53:03 +000045 Add --log-queries=extra option, which makes logs easier
46 to search automatically.
47
RinSatsuki28de3872015-01-10 15:22:21 +000048 Add --min-cache-ttl option. I've resisted this for a long
49 time, on the grounds that disbelieving TTLs is never a
50 good idea, but I've been persuaded that there are
51 sometimes reasons to do it. (Step forward, GFW).
52 To avoid misuse, there's a hard limit on the TTL
53 floor of one hour. Thansk to RinSatsuki for the patch.
Simon Kelley39341552015-01-18 22:11:10 +000054
55 Cope with multiple interfaces with the same link-local
56 address. (IPv6 addresses are scoped, so this is allowed.)
57 Thanks to Cory Benfield for help with this.
Simon Kelley5f4dc5c2015-01-20 20:51:02 +000058
59 Add --dhcp-hostsdir. This allows addition of new host
60 configurations to a running dnsmasq instance much more
61 cheaply than having dnsmasq re-read all its existing
62 configuration each time.
RinSatsuki28de3872015-01-10 15:22:21 +000063
Win King Wan61b838d2015-01-21 20:41:48 +000064 Don't reply to DHCPv6 SOLICIT messages if we're not
65 configured to do stateful DHCPv6. Thanks to Win King Wan
66 for the patch.

Simon Kelley6ef15b32015-01-31 22:44:26 +000068 Fix broken DNSSEC validation of ECDSA signatures.
Simon Kelleyf6e62e22015-03-01 18:17:54 +000069
70 Add --dnssec-timestamp option, which provides an automatic
71 way to detect when the system time becomes valid after boot
72 on systems without an RTC, whilst allowing DNS queries before the
73 clock is valid so that NTP can run. Thanks to
74 Kevin Darbyshire-Bryant for developing this idea.
Stefan Tomanek30d08792015-03-31 22:32:11 +010075
76 Add --tftp-no-fail option. Thanks to Stefan Tomanek for
77 the patch.
Simon Kelley04b0ac02015-04-06 17:19:13 +010078
79 Fix crash caused by looking up servers.bind, CHAOS text record,
80 when more than about five --servers= lines are in the dnsmasq
81 config. This causes memory corruption which causes a crash later.
82 Thanks to Matt Coddington for sterling work chasing this down.

Simon Kelleyc4a09372014-06-02 20:30:07 +010086 Add ra-advrouter mode, for RFC-3775 mobile IPv6 support.
87
88 Add support for "ipsets" in *BSD, using pf. Thanks to
89 Sven Falempim for the patch.
Simon Kelley8e9ffba2014-05-20 20:38:25 +010090
Simon Kelleya0358e52014-06-07 13:38:48 +010091 Fix race condition which could lock up dnsmasq when an
92 interface goes down and up rapidly. Thanks to Conrad
93 Kostecki for helping to chase this down.
Daniel Collinsc4638f92014-06-07 21:21:44 +010094
95 Add DBus methods SetFilterWin2KOption and SetBogusPrivOption
96 Thanks to the Smoothwall project for the patch.
Simon Kelleycdb755c2014-06-18 20:52:53 +010097
98 Fix failure to build against Nettle-3.0. Thanks to Steven
99 Barth for spotting this and finding the fix.
Simon Kelleya0358e52014-06-07 13:38:48 +0100100
Simon Kelley6d8e8ac2014-07-13 22:12:45 +0100101 When assigning existing DHCP leases to intefaces by comparing
102 networks, handle the case that two or more interfaces have the
103 same network part, but different prefix lengths (favour the
104 longer prefix length.) Thanks to Lung-Pin Chang for the
105 patch.
106
Simon Kelleyb5ea1cc2014-07-29 16:34:14 +0100107 Add a mode which detects and removes DNS forwarding loops, ie
108 a query sent to an upstream server returns as a new query to
109 dnsmasq, and would therefore be forwarded again, resulting in
110 a query which loops many times before being dropped. Upstream
111 servers which loop back are disabled and this event is logged.
112 Thanks to Smoothwall for their sponsorship of this feature.
113
Simon Kelley3e1551a2014-09-09 21:46:07 +0100114 Extend --conf-dir to allow filtering of files. So
115 --conf-dir=/etc/dnsmasq.d,\*.conf
116 will load all the files in /etc/dnsmasq.d which end in .conf
Ilya Ponetaev5bf50af2014-09-09 12:46:21 +0100117
Simon Kelley288df492014-09-18 21:48:51 +0100118 Fix bug when resulted in NXDOMAIN answers instead of NODATA in
119 some circumstances.
Simon Kelley57826492014-09-18 22:08:58 +0100120
121 Fix bug which caused dnsmasq to become unresponsive if it
122 failed to send packets due to a network interface disappearing.
123 Thanks to Niels Peen for spotting this.
Simon Kelleybf2db4b2014-09-18 22:10:46 +0100124
125 Fix problem with --local-service option on big-endian platforms
126 Thanks to Richard Genoud for the patch.

Simon Kelley8e9ffba2014-05-20 20:38:25 +0100128
Simon Kelley9d1b22a2014-04-29 13:02:41 +0100129version 2.71
130 Subtle change to error handling to help DNSSEC validation
131 when servers fail to provide NODATA answers for
132 non-existent DS records.
133
134 Tweak code which removes DNSSEC records from answers when
135 not required. Fixes broken answers when additional section
136 has real records in it. Thanks to Marco Davids for the bug
137 report.
138
139 Fix DNSSEC validation of ANY queries. Thanks to Marco Davids
140 for spotting that too.
141
Simon Kelleyb692f232014-05-09 10:29:43 +0100142 Fix total DNS failure and 100% CPU use if cachesize set to zero,
143 regression introduced in 2.69. Thanks to James Hunt and
144 the Ubuntu crowd for assistance in fixing this.
145
Simon Kelley9d1b22a2014-04-29 13:02:41 +0100146
Simon Kelley63758382014-04-16 22:20:55 +0100147version 2.70
148 Fix crash, introduced in 2.69, on TCP request when dnsmasq
149 compiled with DNSSEC support, but running without DNSSEC
150 enabled. Thanks to Manish Sing for spotting that one.
151
Simon Kelley3b1b3e92014-04-23 15:46:05 +0100152 Fix regression which broke ipset functionality. Thanks to
153 Wang Jian for the bug report.
154
Simon Kelley63758382014-04-16 22:20:55 +0100155
Simon Kelley1ee9be42013-12-09 16:50:19 +0000156version 2.69
157 Implement dynamic interface discovery on *BSD. This allows
158 the contructor: syntax to be used in dhcp-range for DHCPv6
159 on the BSD platform. Thanks to Matthias Andree for
160 valuable research on how to implement this.
161
Simon Kelley8db957d2013-12-17 15:47:10 +0000162 Fix infinite loop associated with some --bogus-nxdomain
Simon Kelley74e6b522013-12-17 21:33:53 +0000163 configs. Thanks fogobogo for the bug report.
Simon Kelley8db957d2013-12-17 15:47:10 +0000164
Simon Kelleyae762422014-01-10 18:15:16 +0000165 Fix missing RA RDNS option with configuration like
166 --dhcp-option=option6:23,[::] Thanks to Tsachi Kimeldorfer
167 for spotting the problem.
168
Simon Kelleyc3a04082014-01-11 22:18:19 +0000169 Add [fd00::] and [fe80::] as special addresses in DHCPv6
170 options, analogous to [::]. [fd00::] is replaced with the
171 actual ULA of the interface on the machine running
172 dnsmasq, [fe80::] with the link-local address.
173 Thanks to Tsachi Kimeldorfer for championing this.
174
Simon Kelley613d6c52014-02-04 11:50:11 +0000175 DNSSEC validation and caching. Dnsmasq needs to be
176 compiled with this enabled, with
177
178 make dnsmasq COPTS=-DHAVE_DNSSEC
179
180 this add dependencies on the nettle crypto library and the
181 gmp maths library. It's possible to have these linked
182 statically with
183
184 make dnsmasq COPTS='-DHAVE_DNSSEC -DHAVE_DNSSEC_STATIC'
185
Simon Kelley198d9402014-04-09 20:36:53 +0100186 which bloats the dnsmasq binary, but saves the size of
187 the shared libraries which are much bigger.
188
Simon Kelley613d6c52014-02-04 11:50:11 +0000189 To enable, DNSSEC, you will need a set of
190 trust-anchors. Now that the TLDs are signed, this can be
191 the keys for the root zone, and for convenience they are
192 included in trust-anchors.conf in the dnsmasq
193 distribution. You should of course check that these are
194 legitimate and up-to-date. So, adding
195
196 conf-file=/path/to/trust-anchors.conf
197 dnssec
Simon Kelley1ee9be42013-12-09 16:50:19 +0000198
Simon Kelley613d6c52014-02-04 11:50:11 +0000199 to your config is all thats needed to get things
200 working. The upstream nameservers have to be DNSSEC-capable
201 too, of course. Many ISP nameservers aren't, but the
202 Google public nameservers (8.8.8.8 and 8.8.4.4) are.
203 When DNSSEC is configured, dnsmasq validates any queries
204 for domains which are signed. Query results which are
205 bogus are replaced with SERVFAIL replies, and results
206 which are correctly signed have the AD bit set. In
207 addition, and just as importantly, dnsmasq supplies
208 correct DNSSEC information to clients which are doing
209 their own validation, and caches DNSKEY, DS and RRSIG
210 records, which significantly improve the performance of
211 downstream validators. Setting --log-queries will show
212 DNSSEC in action.
213
Simon Kelley198d9402014-04-09 20:36:53 +0100214 If a domain is returned from an upstream nameserver without
215 DNSSEC signature, dnsmasq by default trusts this. This
216 means that for unsigned zone (still the majority) there
217 is effectively no cost for having DNSSEC enabled. Of course
218 this allows an attacker to replace a signed record with a
219 false unsigned record. This is addressed by the
220 --dnssec-check-unsigned flag, which instructs dnsmasq
221 to prove that an unsigned record is legitimate, by finding
222 a secure proof that the zone containing the record is not
223 signed. Doing this has costs (typically one or two extra
224 upstream queries). It also has a nasty failure mode if
225 dnsmasq's upstream nameservers are not DNSSEC capable.
226 Without --dnssec-check-unsigned using such an upstream
227 server will simply result in not queries being validated;
228 with --dnssec-check-unsigned enabled and a
229 DNSSEC-ignorant upstream server, _all_ queries will fail.
230
231 Note that DNSSEC requires that the local time is valid and
232 accurate, if not then DNSSEC validation will fail. NTP
233 should be running. This presents a problem for routers
234 without a battery-backed clock. To set the time needs NTP
235 to do DNS lookups, but lookups will fail until NTP has run.
236 To address this, there's a flag, --dnssec-no-timecheck
237 which disables the time checks (only) in DNSSEC. When dnsmasq
238 is started and the clock is not synced, this flag should
239 be used. As soon as the clock is synced, SIGHUP dnsmasq.
240 The SIGHUP clears the cache of partially-validated data and
241 resets the no-timecheck flag, so that all DNSSEC checks
242 henceforward will be complete.
243
Simon Kelley613d6c52014-02-04 11:50:11 +0000244 The development of DNSSEC in dnsmasq was started by
245 Giovanni Bajo, to whom huge thanks are owed. It has been
246 supported by Comcast, whose techfund grant has allowed for
247 an invaluable period of full-time work to get it to
248 a workable state.
249
Simon Kelleyde73a492014-02-17 21:43:27 +0000250 Add --rev-server. Thanks to Dave Taht for suggesting this.
Simon Kelley7b1eae42014-02-20 13:43:28 +0000251
252 Add --servers-file. Allows dynamic update of upstream servers
253 full access to configuration.
Simon Kelleyde73a492014-02-17 21:43:27 +0000254
Simon Kelleyc8a80482014-03-05 14:29:54 +0000255 Add --local-service. Accept DNS queries only from hosts
256 whose address is on a local subnet, ie a subnet for which
257 an interface exists on the server. This option
Simon Kelleyf00690f2014-03-12 20:07:12 +0000258 only has effect if there are no --interface --except-interface,
Simon Kelleyc8a80482014-03-05 14:29:54 +0000259 --listen-address or --auth-server options. It is intended
260 to be set as a default on installation, to allow
261 unconfigured installations to be useful but also safe from
262 being used for DNS amplification attacks.
263
Simon Kelley604f7592014-03-22 19:33:43 +0000264 Fix crashes in cache_get_cname_target() when dangling CNAMEs
265 encountered. Thanks to Andy and the rt-n56u project for
266 find this and helping to chase it down.
267
Simon Kelley10068602014-04-03 21:16:40 +0100268 Fix wrong RCODE in authoritative DNS replies to PTR queries. The
269 correct answer was included, but the RCODE was set to NXDOMAIN.
270 Thanks to Craig McQueen for spotting this.
271
Simon Kelley198d9402014-04-09 20:36:53 +0100272 Make statistics available as DNS queries in the .bind TLD as
273 well as logging them.

Simon Kelley376d48c2013-11-13 13:04:30 +0000276version 2.68
277 Use random addresses for DHCPv6 temporary address
278 allocations, instead of algorithmically determined stable
279 addresses.
280
281 Fix bug which meant that the DHCPv6 DUID was not available
282 in DHCP script runs during the lifetime of the dnsmasq
283 process which created the DUID de-novo. Once the DUID was
284 created and stored in the lease file and dnsmasq
285 restarted, this bug disappeared.
286
287 Fix bug introduced in 2.67 which could result in erroneous
288 NXDOMAIN returns to CNAME queries.
289
290 Fix build failures on MacOS X and openBSD.
291
292 Allow subnet specifications in --auth-zone to be interface
293 names as well as address literals. This makes it possible
294 to configure authoritative DNS when local address ranges
295 are dynamic and works much better than the previous
296 work-around which exempted contructed DHCP ranges from the
297 IP address filtering. As a consequence, that work-around
298 is removed. Under certain circumstances, this change wil
299 break existing configuration: if you're relying on the
300 contructed-range exception, you need to change --auth-zone
301 to specify the same interface as is used to construct your
302 DHCP ranges, probably with a trailing "/6" like this:
303 --auth-zone=example.com,eth0/6 to limit the addresses to
304 IPv6 addresses of eth0.
Simon Kelleydd9d9ce2013-11-15 11:24:00 +0000305
306 Fix problems when advertising deleted IPv6 prefixes. If
307 the prefix is deleted (rather than replaced), it doesn't
308 get advertised with zero preferred time. Thanks to Tsachi
309 for the bug report.
Simon Kelley25439062013-11-25 21:14:51 +0000310
311 Fix segfault with some locally configured CNAMEs. Thanks
312 to Andrew Childs for spotting the problem.
313
314 Fix memory leak on re-reading /etc/hosts and friends,
315 introduced in 2.67.
Simon Kelley2329bef2013-12-03 13:41:16 +0000316
317 Check the arrival interface of incoming DNS and TFTP
318 requests via IPv6, even in --bind-interfaces mode. This
319 isn't possible for IPv4 and can generate scary warnings,
320 but as it's always possible for IPv6 (the API always
321 exists) then we should do it always.
Vladislav Grishenko4c82efc2013-12-03 16:05:30 +0000322
323 Tweak the rules on prefix-lengths in --dhcp-range for
324 IPv6. The new rule is that the specified prefix length
325 must be larger than or equal to the prefix length of the
326 corresponding address on the local interface.
327

330 Fix crash if upstream server returns SERVFAIL when
331 --conntrack in use. Thanks to Giacomo Tazzari for finding
332 this and supplying the patch.
Simon Kelleyaa63a212013-04-22 15:01:52 +0100333
334 Repair regression in 2.64. That release stopped sending
335 lease-time information in the reply to DHCPINFORM
336 requests, on the correct grounds that it was a standards
337 violation. However, this broke the dnsmasq-specific
338 dhcp_lease_time utility. Now, DHCPINFORM returns
339 lease-time only if it's specifically requested
340 (maintaining standards) and the dhcp_lease_time utility
341 has been taught to ask for it (restoring functionality).
Simon Kelley86e92f92013-04-23 11:31:39 +0100342
343 Fix --dhcp-match, --dhcp-vendorclass and --dhcp-userclass
344 to work with BOOTP and well as DHCP. Thanks to Peter
345 Korsgaard for spotting the problem.
Simon Kelley2bb73af2013-04-24 17:38:19 +0100346
347 Add --synth-domain. Thanks to Vishvananda Ishaya for
348 suggesting this.
Simon Kelleyd5052fb2013-04-25 12:44:20 +0100349
350 Fix failure to compile ipset.c if old kernel headers are
351 in use. Thanks to Eugene Rudoy for pointing this out.
Simon Kelley3f2873d2013-05-14 11:28:47 +0100352
353 Handle IPv4 interface-address labels in Linux. These are
354 often used to emulate the old IP-alias addresses. Before,
355 using --interface=eth0 would service all the addresses of
356 eth0, including ones configured as aliases, which appear
357 in ifconfig as eth0:0. Now, only addresses with the label
358 eth0 are active. This is not backwards compatible: if you
359 want to continue to bind the aliases too, you need to add
360 eg. --interface=eth0:0 to the config.

Simon Kelleycfcad422013-05-17 11:32:03 +0100362 Fix "failed to set SO_BINDTODEVICE on DHCP socket: Socket

376 to Toke Hoiland-Jorgensen for suggesting this.
377
Marcelo Salhab Brogliato0da5e892013-05-31 11:49:06 +0100378 Log when the maximum number of concurrent DNS queries is
379 reached. Thanks to Marcelo Salhab Brogliato for the patch.

Simon Kelleye2ba0df2013-05-31 17:04:25 +0100381 If wildcards are used in --interface, don't assume that
382 there will only ever be one available interface for DHCP
383 just because there is one at start-up. More may appear, so
384 we can't use SO_BINDTODEVICE. Thanks to Natrio for the bug
385 report.
386
Simon Kelleyb4b93082013-06-19 10:31:23 +0100387 Increase timeout/number of retries in TFTP to accomodate

389 Thanks to Damian Kaczkowski for spotting the problem.

Simon Kelley625ac282013-07-02 21:19:32 +0100391 Fix crash with empty DHCP string options when adding zero
Simon Kelley3953dcc2013-07-03 20:40:45 +0100392 terminator. Thanks to Patrick McLean for the bug report.

Kyle Mesteryd859ca22013-07-24 13:11:58 +0100394 Allow hostnames to start with a number, as allowed in
395 RFC-1123. Thanks to Kyle Mestery for the patch.
396
Roy Marples3f3adae2013-07-25 16:22:46 +0100397 Fixes to DHCP FQDN option handling: don't terminate FQDN
398 if domain not known and allow a FQDN option with blank
399 name to request that a FQDN option is returned in the
400 reply. Thanks to Roy Marples for the patch.
401
Simon Kelleyd9fb0be2013-07-25 21:47:17 +0100402 Make --clear-on-reload apply to setting upstream servers
403 via DBus too.
404
Simon Kelleyef1a94a2013-07-26 13:59:03 +0100405 When the address which triggered the construction of an
406 advertised IPv6 prefix disappears, continue to advertise
407 the prefix for up to 2 hours, with the preferred lifetime
408 set to zero. This satisfies RFC 6204 4.3 L-13 and makes
409 things work better if a prefix disappears without being
410 deprecated first. Thanks to Uwe Schindler for persuasively
411 arguing for this.
412
Simon Kelleyfc4c4fd2013-07-26 15:38:59 +0100413 Fix MAC address enumeration on *BSD. Thanks to Brad Smith

417 reply to DHCPv6 information-request. The lease time of the
418 smallest valid dhcp-range is sent. Thanks to Uwe Schindler
419 for suggesting this.
420
Simon Kelleyedf0bde2013-07-29 17:21:48 +0100421 Make --listen-address higher priority than --except-interface
422 in all circumstances. Thanks to Thomas Hood for the bugreport.
423
Simon Kelley2937f8a2013-07-29 19:49:07 +0100424 Provide independent control over which interfaces get TFTP
425 service. If enable-tftp is given a list of interfaces, then TFTP
426 is provided on those. Without the list, the previous behaviour
427 (provide TFTP to the same interfaces we provide DHCP to)
428 is retained. Thanks to Lonnie Abelbeck for the suggestion.
429

Simon Kelleyc8f2dd82013-09-13 11:22:55 +0100440 Cope with DHCPv6 clients which send REQUESTs without
441 address options - treat them as SOLICIT with rapid commit.
442
Simon Kelley89500e32013-09-20 16:29:20 +0100443 Support identification of clients by MAC address in
444 DHCPv6. When using a relay, the relay must support RFC
445 6939 for this to work. It always works for directly
446 connected clients. Thanks to Vladislav Grishenko
447 for prompting this feature.
Simon Kelley861c8912013-09-25 15:30:30 +0100448
449 Remove the rule for constructed DHCP ranges that the local
450 address must be either the first or last address in the
451 range. This was originally to avoid SLAAC addresses, but
452 we now explicitly autoconfig and privacy addresses instead.
Simon Kelley89500e32013-09-20 16:29:20 +0100453
Simon Kelley889d8a12013-10-02 13:12:09 +0100454 Update Polish translation. Thanks to Jan Psota.

462 inspiration on this.
463
Simon Kelleyed4c0762013-10-08 20:46:34 +0100464 Add --add-subnet configuration, to tell upstream DNS
Simon Kelleyf65b0e52013-10-11 10:19:01 +0100465 servers where the original client is. Thanks to DNSthingy
466 for sponsoring this feature.

Kevin Darbyshire-Bryant8c0b73d2013-10-11 11:56:33 +0100468 Add --quiet-dhcp, --quiet-dhcp6 and --quiet-ra. Thanks to
469 Kevin Darbyshire-Bryant for the initial patch.
470
Simon Kelleyd56a6042013-10-11 14:39:03 +0100471 Allow A/AAAA records created by --interface-name to be the
472 target of --cname. Thanks to Hadmut Danisch for the
473 suggestion.
474
Simon Kelley24b5a5d2013-10-11 15:19:28 +0100475 Avoid treating a --dhcp-host which has an IPv6 address
476 as eligable for use with DHCPv4 on the grounds that it has
477 no address, and vice-versa. Thanks to Yury Konovalov for
478 spotting the problem.
479
Simon Kelley45cca582013-10-15 10:20:13 +0100480 Do a better job caching dangling CNAMEs. Thanks to Yves
481 Dorfsman for spotting the problem.

Vic043c2712013-10-04 15:09:13 +0100483
Simon Kelley333b2ce2013-01-07 21:46:03 +0000484version 2.66
485 Add the ability to act as an authoritative DNS
486 server. Dnsmasq can now answer queries from the wider 'net
487 with local data, as long as the correct NS records are set
488 up. Only local data is provided, to avoid creating an open
489 DNS relay. Zone transfer is supported, to allow secondary
490 servers to be configured.
491
492 Add "constructed DHCP ranges" for DHCPv6. This is intended
493 for IPv6 routers which get prefixes dynamically via prefix
494 delegation. With suitable configuration, stateful DHCPv6
495 and RA can happen automatically as prefixes are delegated
496 and then deprecated, without having to re-write the
497 dnsmasq configuration file or restart the daemon. Thanks to
498 Steven Barth for extensive testing and development work on
499 this idea.
Simon Kelley71c73ac2013-01-08 21:22:24 +0000500
501 Fix crash on startup on Solaris 11. Regression probably
Simon Kelley22ce5502013-01-22 13:53:04 +0000502 introduced in 2.61. Thanks to Geoff Johnstone for the
503 patch.
504
505 Add code to make behaviour for TCP DNS requests that same
506 as for UDP requests, when a request arrives for an allowed
507 address, but via a banned interface. This change is only
508 active on Linux, since the relevant API is missing (AFAIK)
509 on other platforms. Many thanks to Tomas Hozza for
510 spotting the problem, and doing invaluable discovery of
511 the obscure and undocumented API required for the solution.
Simon Kelleya21e27b2013-02-17 16:41:35 +0000512
513 Don't send the default DHCP option advertising dnsmasq as
514 the local DNS server if dnsmasq is configured to not act
515 as DNS server, or it's configured to a non-standard port.
Simon Kelleydd1721c2013-02-18 21:04:04 +0000516
517 Add DNSMASQ_CIRCUIT_ID, DNSMASQ_SUBCRIBER_ID,
518 DNSMASQ_REMOTE_ID variables to the environment of the
Simon Kelley3d77c042013-03-22 10:03:50 +0000519 lease-change script (and the corresponding Lua). These hold
Simon Kelleydd1721c2013-02-18 21:04:04 +0000520 information inserted into the DHCP request by a DHCP relay
521 agent. Thanks to Lakefield Communications for providing a
522 bounty for this addition.
523
Simon Kelley4038ae22013-02-19 16:47:07 +0000524 Fixed crash, introduced in 2.64, whilst handling DHCPv6
525 information-requests with some common configurations.
526 Thanks to Robert M. Albrecht for the bug report and
527 chasing the problem.
528
Jason A. Donenfeld13d86c72013-02-22 18:20:53 +0000529 Add --ipset option. Thanks to Jason A. Donenfeld for the
530 patch.
531
Simon Kelleyc7961072013-02-28 15:17:58 +0000532 Don't erroneously reject some option names in --dhcp-match
Simon Kelley3d77c042013-03-22 10:03:50 +0000533 options. Thanks to Benedikt Hochstrasser for the bug report.
Simon Kelley49333cb2013-03-15 20:30:51 +0000534
535 Allow a trailing '*' wildcard in all interface-name
536 configurations. Thanks to Christian Parpart for the patch.
Simon Kelleyc7961072013-02-28 15:17:58 +0000537
Simon Kelley56a11422013-04-02 17:02:58 +0100538 Handle the situation where libc headers define
539 SO_REUSEPORT, but the kernel in use doesn't, to cope with
540 the introduction of this option to Linux. Thanks to Rich
541 Felker for the bug report.
542
Simon Kelleycd1e04a2013-04-02 20:11:48 +0100543 Update Polish translation. Thanks to Jan Psota.
Simon Kelley0b0a73c2013-04-11 14:07:02 +0100544
545 Fix crash if the configured DHCP lease limit is
546 reached. Regression occurred in 2.61. Thanks to Tsachi for
547 the bug report.
Simon Kelleycd1e04a2013-04-02 20:11:48 +0100548
Simon Kelley834f36f2013-04-17 13:52:49 +0100549 Update the French translation. Thanks to Gildas le Nadan.

Simon Kelley49333cb2013-03-15 20:30:51 +0000551
Simon Kelleyee86ce62012-12-07 11:54:46 +0000552version 2.65
553 Fix regression which broke forwarding of queries sent via
554 TCP which are not for A and AAAA and which were directed to
555 non-default servers. Thanks to Niax for the bug report.
556
Simon Kelleyb5a8dd12012-12-10 11:37:25 +0000557 Fix failure to build with DHCP support excluded. Thanks to
558 Gustavo Zacarias for the patch.
Simon Kelley1d6c6392012-12-14 11:19:36 +0000559
560 Fix nasty regression in 2.64 which completely broke cacheing.
Simon Kelleyb5a8dd12012-12-10 11:37:25 +0000561
562
Simon Kelley2e34ac12012-08-29 14:15:25 +0100563version 2.64
564 Handle DHCP FQDN options with all flag bits zero and
565 --dhcp-client-update set. Thanks to Bernd Krumbroeck for
566 spotting the problem.
567
Simon Kelley12d71ed2012-08-30 15:16:41 +0100568 Finesse the check for /etc/hosts names which conflict with
569 DHCP names. Previously a name/address pair in /etc/hosts
570 which didn't match the name/address of a DHCP lease would
571 generate a warning. Now that only happesn if there is not
572 also a match. This allows multiple addresses for a name in
573 /etc/hosts with one of them assigned via DHCP.
574
Simon Kelley4d0f5b42012-09-05 23:29:30 +0100575 Fix broken vendor-option processing for BOOTP. Thanks to
576 Hans-Joachim Baader for the bug report.
577
Simon Kelleydfb23b32012-09-18 21:44:47 +0100578 Don't report spurious netlink errors, regression in

Simon Kelley1d860412012-09-20 20:48:04 +0100593 Add --max-cache-ttl option. Thanks to Dennis Kaarsemaker
594 for the patch.
595
Simon Kelleye4807d82012-09-27 21:52:26 +0100596 Fix breakage of --host-record parsing, resulting in
597 infinte loop at startup. Regression in 2.63. Thanks to
598 Haim Gelfenbeyn for spotting this.
599
Simon Kelley20223102012-10-15 10:41:17 +0100600 Set SO_REUSEADDRESS and SO_V6ONLY options on the DHCPv6
601 socket, this allows multiple instances of dnsmasq on a
602 single machine, in the same way as for DHCPv4. Thanks to
603 Gene Czarcinski and Vladislav Grishenko for work on this.
604
Simon Kelleybe6cfb42012-10-16 20:38:31 +0100605 Fix DHCPv6 to do access control correctly when it's
606 configured with --listen-address. Thanks to
607 Gene Czarcinski for sorting this out.
608
Simon Kelley819ff4d2012-10-21 18:25:12 +0100609 Add a "wildcard" dhcp-range which works for any IPv6
610 subnet, --dhcp-range=::,static Useful for Stateless
611 DHCPv6. Thanks to Vladislav Grishenko for the patch.
612
Simon Kelleyd1a59752012-11-05 16:50:30 +0000613 Don't include lease-time in DHCPACK replies to DHCPINFORM
614 queries, since RFC-2131 says we shouldn't. Thanks to
615 Wouter Ibens for pointing this out.
Simon Kelley8e4b8792012-11-14 14:12:56 +0000616
617 Makefile tweak to do dependency checking on header files.
618 Thanks to Johan Peeters for the patch.
Simon Kelleyd89fb4e2012-12-01 21:21:13 +0000619
620 Check interface for outgoing unsolicited router
621 advertisements, rather than relying on interface address
622 configuration. Thanks to Gene Czarinski for the patch.
Simon Kelley29d28dd2012-12-03 14:05:59 +0000623
624 Handle better attempts to transmit on interfaces which are
625 still doing DAD, and specifically do not just transmit
626 without setting source address and interface, since this
627 can cause very puzzling effects when a router
628 advertisement goes astray. Thanks again to Gene Czarinski.
629
630 Get RA timers right when there is more than one
631 dhcp-range on a subnet.

636
Simon Kelley8b3ae2f2012-06-13 13:43:49 +0100637 Check that tftp-root directories are accessible before
638 start-up. Thanks to Daniel Veillard for the initial patch.
639
640 Allow more than one --tfp-root flag. The per-interface
641 stuff is pointless without that.
642
Simon Kelley54dd3932012-06-20 11:23:38 +0100643 Add --bind-dynamic. A hybrid mode between the default and
644 --bind-interfaces which copes with dynamically created
645 interfaces.
Simon Kelley6b617c02012-06-29 21:15:42 +0100646

Simon Kelley8bc4cec2012-07-03 21:04:11 +0100650 Remove the interface:<interface> argument in --dhcp-range, and
651 the interface argument to --enable-tftp. These were a
652 still-born attempt to allow automatic isolated
653 configuration by libvirt, but have never (to my knowledge)
654 been used, had very strange semantics, and have been
655 superceded by other mechanisms.
656
Simon Kelleyc4a7f902012-07-12 20:52:12 +0100657 Fixed bug logging filenames when duplicate dhcp-host

Simon Kelley42243212012-07-20 15:19:18 +0100665 Teach DHCPv6 about the RFC 4242 information-refresh-time
666 option, and add parsing if the minutes, hours and days
667 format for options. Thanks to Francois-Xavier Le Bail for
668 the suggestion.
669
670 Allow "w" (for week) as multiplier in lease times, as well
671 as seconds, minutes, hours and days. Álvaro Gámez Machado
672 spotted the ommission.
Simon Kelleyc4c04882012-08-06 20:09:15 +0100673

690
Simon Kelley919dd7c2012-05-12 15:23:09 +0100691 Fixed bug which caused missing periodic router
692 advertisements with some configurations. Thanks to
693 Vladislav Grishenko for the patch.
694
Simon Kelleyc64b7f62012-05-18 10:19:59 +0100695 Fixed bug which broke DHCPv6/RA with prefix lengths
696 which are not divisible by 8. Thanks to Andre Coetzee
697 for spotting this.
698
Simon Kelley18c63ef2012-05-21 14:34:15 +0100699 Fix non-response to router-solicitations when
700 router-advertisement configured, but DHCPv6 not
701 configured. Thanks to Marien Zwart for the patch.

Simon Kelley9f7f3b12012-05-28 21:39:57 +0100703 Add --dns-rr, to allow arbitrary DNS resource records.
704
Simon Kelley5ae34bf2012-06-04 21:14:03 +0100705 Fixed bug which broke RA scheduling when an interface had
706 two addresses in the same network. Thanks to Jim Bos for
707 his help nailing this.
708
Simon Kelleyeabc6dd2012-03-07 20:28:20 +0000709version 2.61
710 Re-write interface discovery code on *BSD to use
711 getifaddrs. This is more portable, more straightforward,
712 and allows us to find the prefix length for IPv6
713 addresses.
714
Simon Kelley01d1b8d2012-03-28 21:37:25 +0100715 Add ra-names, ra-stateless and slaac keywords for DHCPv6.
716 Dnsmasq can now synthesise AAAA records for dual-stack
717 hosts which get IPv6 addresses via SLAAC. It is also now
718 possible to use SLAAC and stateless DHCPv6, and to
719 tell clients to use SLAAC addresses as well as DHCP ones.
720 Thanks to Dave Taht for help with this.
Simon Kelley7023e382012-03-09 12:05:49 +0000721
Simon Kelley8b372702012-03-09 17:45:10 +0000722 Add --dhcp-duid to allow DUID-EN uids to be used.
723
Simon Kelley8643ec72012-03-12 20:04:14 +0000724 Explicity send DHCPv6 replies to the correct port, instead
725 of relying on clients to send requests with the correct
726 source address, since at least one client in the wild gets
Simon Kelley8358e0f2012-04-29 21:53:09 +0100727 this wrong. Thanks to Conrad Kostecki for help tracking
Simon Kelley8643ec72012-03-12 20:04:14 +0000728 this down.
Simon Kelleyeabc6dd2012-03-07 20:28:20 +0000729
Simon Kelley8643ec72012-03-12 20:04:14 +0000730 Send a preference value of 255 in DHCPv6 replies when
731 --dhcp-authoritative is in effect. This tells clients not
732 to wait around for other DHCP servers.
733
734 Better logging of DHCPv6 options.
735
Simon Kelleye759d422012-03-16 13:18:57 +0000736 Add --host-record. Thanks to Rob Zwissler for the
737 suggestion.
738
Simon Kelleya9530962012-03-20 22:07:35 +0000739 Invoke the DHCP script with action "tftp" when a TFTP file
740 transfer completes. The size of the file, address to which
741 it was sent and complete pathname are supplied. Note that
742 version 2.60 introduced some script incompatibilties
743 associated with DHCPv6, and this is a further change. To
744 be safe, scripts should ignore unknown actions, and if
745 not IPv6-aware, should exit if the environment
746 variable DNSMASQ_IAID is set. The use-case for this is
747 to track netboot/install. Suggestion from Shantanu
748 Gadgil.
749
750 Update contrib/port-forward/dnsmasq-portforward to reflect
751 the above.
752
753 Set the environment variable DNSMASQ_LOG_DHCP when running
754 the script id --log-dhcp is in effect, so that script can
Simon Kelley52d4abf2012-03-21 21:39:48 +0000755 taylor their logging verbosity. Suggestion from Malte
756 Forkel.
757
758 Arrange that addresses specified with --listen-address
759 work even if there is no interface carrying the
760 address. This is chiefly useful for IPv4 loopback
761 addresses, where any address in 127.0.0.0/8 is a valid
762 loopback address, but normally only 127.0.0.1 appears on
763 the lo interface. Thanks to Mathieu Trudel-Lapierre for
764 the idea and initial patch.
Simon Kelleya9530962012-03-20 22:07:35 +0000765
Simon Kelley7d2b5c92012-03-23 10:00:02 +0000766 Fix crash, introduced in 2.60, when a DHCPINFORM is
767 received from a network which has no valid dhcp-range.
768 Thanks to Stephane Glondu for the bug report.
769
Simon Kelleyc8257542012-03-28 21:15:41 +0100770 Add a new DHCP lease time keyword, "deprecated" for
771 --dhcp-range. This is only valid for IPv6, and sets the
772 preffered lease time for both DHCP and RA to zero. The
773 effect is that clients can continue to use the address
774 for existing connections, but new connections will use
775 other addresses, if they exist. This makes hitless
776 renumbering at least possible.
777
778 Fix bug in address6_available() which caused DHCPv6 lease
Simon Kelley8358e0f2012-04-29 21:53:09 +0100779 aquisition to fail if more than one dhcp-range in use.

Simon Kelleyc8257542012-03-28 21:15:41 +0100787
Simon Kelley1023dcb2012-04-09 18:00:08 +0100788 Don't cache data from non-recursive nameservers, since it
789 may erroneously look like a valid CNAME to a non-exitant
790 name. Thanks to Ben Winslow for finding this.
Simon Kelley9380ba72012-04-16 14:41:56 +0100791
792 Call SO_BINDTODEVICE on the DHCP socket(s) when doing DHCP
Simon Kelley8358e0f2012-04-29 21:53:09 +0100793 on exactly one interface and --bind-interfaces is set. This
Simon Kelley9380ba72012-04-16 14:41:56 +0100794 makes the OpenStack use-case of one dnsmasq per virtual
795 interface work. This is only available on Linux; it's not
796 supported on other platforms. Thanks to Vishvananda Ishaya
Simon Kelleye46164e2012-04-16 16:39:38 +0100797 and the OpenStack team for the suggestion.
798
799 Updated French translation. Thanks to Gildas Le Nadan.
Simon Kelleyd1c759c2012-04-16 17:26:19 +0100800
801 Give correct from-cache answers to explict CNAME queries.
802 Thanks to Rob Zwissler for spotting this.

Simon Kelleyfc92ead2012-04-22 21:28:24 +0100804 Add --tftp-lowercase option. Thanks to Oliver Rath for the

Simon Kelleydcffad22012-04-24 15:25:18 +0100806
807 Ensure that the DBus DhcpLeaseUpdated events are generated
808 when a lease goes through INIT_REBOOT state, even if the
Simon Kelley8358e0f2012-04-29 21:53:09 +0100809 dhcp-script is not in use. Thanks to Antoaneta-Ecaterina

817 Fix compilation problem in Mac OS X Lion. Thanks to Olaf
818 Flebbe for the patch.
Simon Kelley74c95c22011-10-19 09:33:39 +0100819
Simon Kelleyc72daea2012-01-05 21:33:27 +0000820 Fix DHCP when using --listen-address with an IP address
821 which is not the primary address of an interface.
822
823 Add --dhcp-client-update option.
824
825 Add Lua integration. Dnsmasq can now execute a DHCP
826 lease-change script written in Lua. This needs to be
827 enabled at compile time by setting HAVE_LUASCRIPT in
828 src/config.h or running "make COPTS=-DHAVE_LUASCRIPT"
829 Thanks to Jan-Piet Mens for the idea and proof-of-concept
830 implementation.
831
832 Tidied src/config.h to distinguish between
833 platform-dependent compile-time options which are selected
834 automatically, and builder-selectable compile time
835 options. Document the latter better, and describe how to
836 set them from the make command line.
837
838 Tidied up IPPROTO_IP/SOL_IP (and IPv6 equivalent)
839 confusion. IPPROTO_IP works everywhere now.
840
841 Set TOS on DHCP sockets, this improves things on busy
842 wireless networks. Thanks to Dave Taht for the patch.
843
Simon Kelley984d2fd2012-01-06 14:34:32 +0000844 Determine VERSION automatically based on git magic:
845 release tags or hash values.
Simon Kelleyc72daea2012-01-05 21:33:27 +0000846
Simon Kelleya2761752012-01-18 16:07:21 +0000847 Improve start-up speed when reading large hosts files
848 containing many distinct addresses.
849
850 Fix problem if dnsmasq is started without the stdin,
851 stdout and stderr file descriptors open. This can manifest
852 itself as 100% CPU use. Thanks to Chris Moore for finding
853 this.
854
Simon Kelley9bbc8872012-02-09 21:33:09 +0000855 Fix shell-scripting bug in bld/pkg-wrapper. Thanks to
856 Mark Mitchell for the patch.
857
Simon Kelley751d6f42012-02-10 15:24:51 +0000858 Allow the TFP server or boot server in --pxe-service, to
859 be a domain name instead of an IP address. This allows for
860 round-robin to multiple servers, in the same way as
861 --dhcp-boot. A good suggestion from Cristiano Cumer.
862
Simon Kelleyfdacfb02012-02-28 15:20:25 +0000863 Support BUILDDIR variable in the Makefile. Allows builds
864 for multiple archs from the same source tree with eg.
865 make BUILDDIR=linux (relative to dnsmasq tree)
866 make BUILDDIR=/tmp/openbsd (absolute path)
Simon Kelleye5ffdb92012-02-13 14:19:25 +0000867 If BUILDDIR is not set, compilation happens in the src
Simon Kelleyb36ae192012-02-13 12:54:34 +0000868 directory, as before. Suggestion from Mark Mitchell.
869
Simon Kelleyfdacfb02012-02-28 15:20:25 +0000870 Support DHCPv6. Support is there for the sort of things
871 the existing v4 server does, including tags, options,
872 static addresses and relay support. Missing is prefix
873 delegation, which is probably not required in the dnsmasq
874 niche, and an easy way to accept prefix delegations from
875 an upstream DHCPv6 server, which is. Future plans include
876 support for DHCPv6 router option and MAC address option
877 (to make selecting clients by MAC address work like IPv4).
878 These will be added as the standards mature.
879 This code has been tested, but this is the first release,
880 so don't bet the farm on it just yet. Many thanks to all
881 testers who have got it this far.
Simon Kelley1adadf52012-02-13 22:15:58 +0000882
Simon Kelleyac8540c2012-02-26 20:57:31 +0000883 Support IPv6 router advertisements. This is a
884 simple-minded implementation, aimed at providing the
885 vestigial RA needed to go alongside IPv6. Is picks up
886 configuration from the DHCPv6 conf, and should just need
887 enabling with --enable-ra.
888
Simon Kelley552af8b2012-02-29 20:10:31 +0000889 Fix long-standing wrinkle with --localise-queries that
890 could result in wrong answers when DNS packets arrive
891 via an interface other than the expected one. Thanks to
892 Lorenzo Milesi and John Hanks for spotting this one.
Simon Kelley71ee7ee2012-03-03 18:06:49 +0000893

897
898
Simon Kelleyc72daea2012-01-05 21:33:27 +0000899version 2.59
900 Fix regression in 2.58 which caused failure to start up
901 with some combinations of dnsmasq config and IPv6 kernel
902 network config. Thanks to Brielle Bruns for the bug
903 report.
904
905 Improve dnsmasq's behaviour when network interfaces are
906 still doing duplicate address detection (DAD). Previously,
907 dnsmasq would wait up to 20 seconds at start-up for the
908 DAD state to terminate. This is broken for bridge
909 interfaces on recent Linux kernels, which don't start DAD
910 until the bridge comes up, and so can take arbitrary
911 time. The new behaviour lets dnsmasq poll for an arbitrary
912 time whilst providing service on other interfaces. Thanks
913 to Stephen Hemminger for pointing out the problem.
Simon Kelley74c95c22011-10-19 09:33:39 +0100914
915
Simon Kelley7de060b2011-08-26 17:24:52 +0100916version 2.58
917 Provide a definition of the SA_SIZE macro where it's
918 missing. Fixes build failure on openBSD.
919
920 Don't include a zero terminator at the end of messages
921 sent to /dev/log when /dev/log is a datagram socket.
922 Thanks to Didier Rabound for spotting the problem.
923
924 Add --dhcp-sequential-ip flag, to force allocation of IP
925 addresses in ascending order. Note that the default
926 pseudo-random mode is in general better but some
927 server-deployment applications need this.
928
929 Fix problem where a server-id of 0.0.0.0 is sent to a
930 client when a dhcp-relay is in use if a client renews a
931 lease after dnsmasq restart and before any clients on the
932 subnet get a new lease. Thanks to Mike Ruiz for assistance
933 in chasing this one down.
934
935 Don't return NXDOMAIN to an AAAA query if we have CNAME
936 which points to an A record only: NODATA is the correct
937 reply in this case. Thanks to Tom Fernandes for spotting
938 the problem.
939
940 Relax the need to supply a netmask in --dhcp-range for
941 networks which use a DHCP relay. Whilst this is still
942 desireable, in the absence of a netmask dnsmasq will use
943 a default based on the class (A, B, or C) of the address.
944 This should at least remove a cause of mysterious failure
945 for people using RFC1918 addresses and relays.
946
947 Add support for Linux conntrack connection marking. If
948 enabled with --conntrack, the connection mark for incoming
949 DNS queries will be copied to the outgoing connections
950 used to answer those queries. This allows clever firewall
951 and accounting stuff. Only available if dnsmasq is
952 compiled with HAVE_CONNTRACK and adds a dependency on
953 libnetfilter-conntrack. Thanks to Ed Wildgoose for the
954 initial idea, testing and sponsorship of this function.
955
956 Provide a sane error message when someone attempts to
957 match a tag in --dhcp-host.
958
959 Tweak the behaviour of --domain-needed, to avoid problems
960 with recursive nameservers downstream of dnsmasq. The new
961 behaviour only stops A and AAAA queries, and returns
962 NODATA rather than NXDOMAIN replies.
963
964 Efficiency fix for very large DHCP configurations, thanks
965 to James Gartrell and Mike Ruiz for help with this.
966
967 Allow the TFTP-server address in --dhcp-boot to be a
968 domain-name which is looked up in /etc/hosts. This can
969 give multiple IP addresses which are used round-robin,
970 thus doing TFTP server load-balancing. Thanks to Sushil
971 Agrawal for the patch.
972
973 When two tagged dhcp-options for a particular option
974 number are both valid, use the one which is valid without
975 a tag from the dhcp-range. Allows overriding of the value
976 of a DHCP option for a particular host as well as
977 per-network values. So
978 --dhcp-range=set:interface1,......
979 --dhcp-host=set:myhost,.....
980 --dhcp-option=tag:interface1,option:nis-domain,"domain1"
981 --dhcp-option=tag:myhost,option:nis-domain,"domain2"
982 will set the NIS-domain to domain1 for hosts in the range, but
983 override that to domain2 for a particular host.
984
985 Fix bug which resulted in truncated files and timeouts for
986 some TFTP transfers. The bug only occurs with netascii
987 transfers and needs an unfortunate relationship between
988 file size, blocksize and the number of newlines in the
989 last block before it manifests itself. Many thanks to
990 Alkis Georgopoulos for spotting the problem and providing
991 a comprehensive test-case.
992
993 Fix regression in TFTP server on *BSD platforms introduced
994 in version 2.56, due to confusion with sockaddr
Simon Kelleyde604c12012-10-19 09:50:01 +0100995 length. Many thanks to Loic Pefferkorn for finding this.
Simon Kelley7de060b2011-08-26 17:24:52 +0100996
997 Support scope-ids in IPv6 addresses of nameservers from
998 /etc/resolv.conf and in --server options. Eg
999 nameserver fe80::202:a412:4512:7bbf%eth0 or
1000 server=fe80::202:a412:4512:7bbf%eth0. Thanks to
1001 Michael Stapelberg for the suggestion.
1002
1003 Update Polish translation, thanks to Jan Psota.

1007
Simon Kelley572b41e2011-02-18 18:11:18 +00001008version 2.57
1009 Add patches to allow build under Android.
1010
1011 Provide our own header for the DNS protocol, rather than
1012 relying on arpa/nameser.h. This has proved more or less
1013 defective over the years and the final straw is that it's
1014 effectively empty on Android.
1015
1016 Fix regression in 2.56 which caused hex constants in
1017 configuration to be rejected if they contain the '*'
1018 wildcard.
1019
1020 Correct wrong casts of arguments to ctype.h functions,
1021 isdigit(), isxdigit() etc. Thanks to Matthias Andree for
1022 spotting this.
1023
1024 Allow build with IDN support independently from i18n.
1025 IDN support continues to be included automatically
1026 when i18n is included.
1027 'make COPTS=-DHAVE_IDN' is the magic incantation.
1028
1029 Modify check on extraneous command line junk (added in
1030 2.56) so that it doesn't complain about extra _empty_
1031 arguments. Otherwise this breaks libvirt.
1032
1033
Simon Kelley28866e92011-02-14 20:19:14 +00001034version 2.56
1035 Add a patch to allow dnsmasq to get interface names right in a
1036 Solaris zone. Thanks to Dj Padzensky for this.
1037
1038 Improve data-type parsing heuristics so that
1039 --dhcp-option=option:domain-search,.
1040 treats the value as a string and not an IP address.
1041 Thanks to Clemens Fischer for spotting that.
1042
1043 Add IPv6 support to the TFTP server. Many thanks to Jan
1044 'RedBully' Seiffert for the patches.
1045
1046 Log DNS queries at level LOG_INFO, rather then
1047 LOG_DEBUG. This makes things consistent with DHCP
1048 logging. Thanks to Adam Pribyl for spotting the problem.
1049
1050 Ensure that dnsmasq terminates cleanly when using
1051 --syslog-async even if it cannot make a connection to the
1052 syslogd.
1053
1054 Add --add-mac option. This is to support currently
1055 experimental DNS filtering facilities. Thanks to Benjamin
1056 Petrin for the orignal patch.
1057
1058 Fix bug which meant that tags were ignored in dhcp-range
1059 configuration specifying PXE-proxy service. Thanks to
1060 Cristiano Cumer for spotting this.
1061
1062 Raise an error if there is extra junk, not part of an
1063 option, on the command line.
1064
1065 Flag a couple of log messages in cache.c as coming from
1066 the DHCP subsystem. Thanks to Olaf Westrik for the patch.
1067
1068 Omit timestamps from logs when a) logging to stderr and
1069 b) --keep-in-forground is set. The logging facility on the
1070 other end of stderr can be assumned to supply them. Thanks
1071 to John Hallam for the patch.
1072
1073 Don't complain about strings longer than 255 characters in
1074 --txt-record, just split the long strings into 255
1075 character chunks instead.
1076
1077 Fix crash on double-free. This bug can only happen when
1078 dhcp-script is in use and then only in rare circumstances
1079 triggered by high DHCP transaction rate and a slow
1080 script. Thanks to Ferenc Wagner for finding the problem.
1081
1082 Only log that a file has been sent by TFTP after the
1083 transfer has completed succesfully.
1084
1085 A good suggestion from Ferenc Wagner: extend
1086 the --domain option to allow this sort of thing:
1087 --domain=thekelleys.org.uk,192.168.0.0/24,local
1088 which automatically creates
1089 --local=/thekelleys.org.uk/
1090 --local=/0.168.192.in-addr.arpa/
1091
1092 Tighten up syntax checking of hex contants in the config
1093 file. Thanks to Fred Damen for spotting this.
1094
1095 Add dnsmasq logo/icon, contributed by Justin Swift. Many
1096 thanks for that.
1097
1098 Never cache DNS replies which have the 'cd' bit set, or
1099 which result from queries forwarded with the 'cd' bit
1100 set. The 'cd' bit instructs a DNSSEC validating server
1101 upstream to ignore signature failures and return replies
1102 anyway. Without this change it's possible to pollute the
1103 dnsmasq cache with bad data by making a query with the
1104 'cd' bit set and subsequent queries would return this data
1105 without its being marked as suspect. Thanks to Anders
1106 Kaseorg for pointing out this problem.
1107
1108 Add --proxy-dnssec flag, for compliance with RFC
1109 4035. Dnsmasq will now clear the 'ad' bit in answers returned
1110 from upstream validating nameservers unless this option is
1111 set.
1112
1113 Allow a filename of "-" for --conf-file to read
1114 stdin. Suggestion from Timothy Redaelli.
1115
1116 Rotate the order of SRV records in replies, to provide
1117 round-robin load balancing when all the priorities are
1118 equal. Thanks to Peter McKinney for the suggestion.
1119
1120 Edit
1121 contrib/MacOSX-launchd/uk.org.thekelleys.dnsmasq.plist
1122 so that it doesn't log all queries to a file by
1123 default. Thanks again to Peter McKinney.
1124
1125 By default, setting an IPv4 address for a domain but not
1126 an IPv6 address causes dnsmasq to return
1127 an NODATA reply for IPv6 (or vice-versa). So
1128 --address=/google.com/1.2.3.4 stops IPv6 queries for
1129 *google.com from being forwarded. Make it possible to
1130 override this behaviour by defining the sematics if the
1131 same domain appears in both --server and --address.
1132 In that case, the --address has priority for the address
1133 family in which is appears, but the --server has priority
1134 of the address family which doesn't appear in --adddress
1135 So:
1136 --address=/google.com/1.2.3.4
1137 --server=/google.com/#
1138 will return 1.2.3.4 for IPv4 queries for *.google.com but
1139 forward IPv6 queries to the normal upstream nameserver.
1140 Similarly when setting an IPv6 address
1141 only this will allow forwarding of IPv4 queries. Thanks to
1142 William for pointing out the need for this.
1143
1144 Allow more than one --dhcp-optsfile and --dhcp-hostsfile
1145 and make them understand directories as arguments in the
1146 same way as --addn-hosts. Suggestion from John Hanks.
1147
1148 Ignore rebinding requests for leases we don't know
1149 about. Rebind is broadcast, so we might get to overhear a
1150 request meant for another DHCP server. NAKing this is
1151 wrong. Thanks to Brad D'Hondt for assistance with this.

Simon Kelley8ef5ada2010-06-03 19:42:45 +01001174version 2.53
1175 Fix failure to compile on Debian/kFreeBSD. Thanks to
1176 Axel Beckert and Petr Salinger.
1177
1178 Fix code to avoid scary strict-aliasing warnings
1179 generated by gcc 4.4.
1180
1181 Added FAQ entry warning about DHCP failures with Vista
1182 when firewalls block 255.255.255.255.
1183
1184 Fixed bug which caused bad things to happen if a
1185 resolv.conf file which exists is subsequently removed.
1186 Thanks to Nikolai Saoukh for the patch.
1187
1188 Rationalised the DHCP tag system. Every configuration item
1189 which can set a tag does so by adding "set:<tag>" and
1190 every configuration item which is conditional on a tag is
1191 made so by "tag:<tag>". The NOT operator changes to '!',
1192 which is a bit more intuitive too. Dhcp-host directives
1193 can set more than one tag now. The old '#' NOT,
1194 "net:" prefix and no-prefixes are still honoured, so
1195 no existing config file needs to be changed, but
1196 the documentation and new-style config files should be
1197 much less confusing.
1198
1199 Added --tag-if to allow boolean operations on tags.
1200 This allows complicated logic to be clearer and more
1201 general. A great suggestion from Richard Voigt.
1202
1203 Add broadcast/unicast information to DHCP logging.
1204
1205 Allow --dhcp-broadcast to be unconditional.
1206
1207 Fixed incorrect behaviour with NOT <tag> conditionals in
1208 dhcp-options. Thanks to Max Turkewitz for assistance
1209 finding this.
1210
1211 If we send vendor-class encapsulated options based on the
1212 vendor-class supplied by the client, and no explicit
1213 vendor-class option is given, echo back the vendor-class
1214 from the client.
1215
1216 Fix bug which stopped dnsmasq from matching both a
1217 circuitid and a remoteid. Thanks to Ignacio Bravo for
1218 finding this.
1219
1220 Add --dhcp-proxy, which makes it possible to configure
1221 dnsmasq to use a DHCP relay agent as a full proxy, with
1222 all DHCP messages passing through the proxy. This is
1223 useful if the relay adds extra information to the packets
1224 it forwards, but cannot be configured with the RFC 5107
1225 server-override option.
1226
1227 Added interface:<iface name> part to dhcp-range. The
1228 semantics of this are very odd at first sight, but it
1229 allows a single line of the form
1230 dhcp-range=interface:virt0,192.168.0.4,192.168.0.200
1231 to be added to dnsmasq configuration which then supplies
1232 DHCP and DNS services to that interface, without affecting
1233 what services are supplied to other interfaces and
1234 irrespective of the existance or lack of
1235 interface=<interface>
1236 lines elsewhere in the dnsmasq configuration. The idea is
1237 that such a line can be added automatically by libvirt
1238 or equivalent systems, without disturbing any manual
1239 configuration.
1240
1241 Similarly to the above, allow --enable-tftp=<interface>
1242
1243 Allow a TFTP root to be set separately for requests via
1244 different interfaces, --tftp-root=<path>,<interface>
1245
1246 Correctly handle and log clashes between CNAMES and
1247 DNS names being given to DHCP leases. This fixes a bug
1248 which caused nonsense IP addresses to be logged. Thanks to
1249 Sergei Zhirikov for finding and analysing the problem.
1250
1251 Tweak flush_log so as to avoid leaving the log
1252 file in non-blocking mode. O_NONBLOCK is a property of the
1253 file, not the process/descriptor.
1254
1255 Fix contrib/Solaris10/create_package
1256 (/usr/man -> /usr/share/man) Thanks to Vita Batrla.
1257
1258 Fix a problem where, if a client got a lease, then went
1259 to another subnet and got another lease, then moved back,
1260 it couldn't resume the old lease, but would instead get
1261 a new address. Thanks to Leonardo Rodrigues for spotting
1262 this and testing the fix.
1263
1264 Fix weird bug which sometimes omitted certain characters
1265 from the start of quoted strings in dhcp-options. Thanks
1266 to Dayton Turner for spotting the problem.
1267
1268 Add facility to redirect some domains to the standard
1269 upstream servers: this allows something like
1270 --server=/google.com/1.2.3.4 --server=/www.google.com/#
1271 which will send queries for *.google.com to 1.2.3.4,
1272 except *www.google.com which will be forwarded as usual.
1273 Thanks to AJ Weber for prompting this addition.
1274
1275 Improve the hash-algorithm used to generate IP addresses
1276 from MAC addresses during initial DHCP address
1277 allocation. This improves performance when large numbers
1278 of hosts with similar MAC addresses all try and get an IP
1279 address at the same time. Thanks to Paul Smith for his
1280 work on this.
1281
1282 Tweak DHCP code so that --bridge-interface can be used to
1283 select which IP alias of an interface should be used for
1284 DHCP purposes on Linux. If eth0 has an alias eth0:dhcp
1285 then adding --bridge-interface=eth0:dhcp,eth0 will use
1286 the address of eth0:dhcp to determine the correct subnet
1287 for DHCP address allocation. Thanks to Pawel Golaszewski
1288 for prompting this and Eric Cooper for further testing.
1289
1290 Add --dhcp-generate-names. Suggestion by Ferenc Wagner.
1291
1292 Tweak DNS server selection algorithm when there is more
1293 than one server available for a domain, eg.
1294 --server=/mydomain/1.1.1.1
1295 --server=/mydomain/2.2.2.2
1296 Thanks to Alberto Cuesta-Canada for spotting a weakness
1297 here.
1298
1299 Add --max-ttl. Thanks to Fredrik Ringertz for the patch.
1300
1301 Allow --log-facility=- to force all logging to
1302 stderr. Suggestion from Clemens Fischer.
1303
1304 Fix regression which caused configuration like
1305 --address=/.domain.com/1.2.3.4 to be rejected. The dot to the
1306 left of the domain has been implied and not required for a
1307 long time, but it should be accepted for backward
1308 compatibility. Thanks to Andrew Burcin for spotting this.
1309
1310 Add --rebind-domain-ok and --rebind-localhost-ok.
1311 Suggestion from Clemens Fischer.
1312
1313 Log replies to queries of type TXT, when --log-queries
1314 is set.
1315
1316 Fix compiler warnings when compiled with -DNO_DHCP. Thanks
1317 to Shantanu Gadgil for the patch.
1318
1319 Updated French translation. Thanks to Gildas Le Nadan.
1320
1321 Updated Polish translation. Thanks to Jan Psota.
1322
1323 Updated German translation. Thanks to Matthias Andree.
1324
1325 Added contrib/static-arp, thanks to Darren Hoo.
1326
1327 Fix corruption of the domain when a name from /etc/hosts
1328 overrides one supplied by a DHCP client. Thanks to Fedor
1329 Kozhevnikov for spotting the problem.
1330
1331 Updated Spanish translation. Thanks to Chris Chatham.
1332
1333
Simon Kelley316e2732010-01-22 20:16:09 +00001334version 2.52
1335 Work around a Linux kernel bug which insists that the
1336 length of the option passed to setsockopt must be at least
1337 sizeof(int) bytes, even if we're calling SO_BINDTODEVICE
1338 and the device name is "lo". Note that this is fixed
1339 in kernel 2.6.31, but the workaround is harmless and
1340 allows earlier kernels to be used. Also fix dnsmasq
1341 bug which reported the wrong address when this failed.
1342 Thanks to Fedor for finding this.
1343
1344 The API for IPv6 PKTINFO changed around Linux kernel
1345 2.6.14. Workaround the case where dnsmasq is compiled
1346 against newer headers, but then run on an old kernel:
1347 necessary for some *WRT distros.
1348
1349 Re-read the set of network interfaces when re-loading
1350 /etc/resolv.conf if --bind-interfaces is not set. This
1351 handles the case that loopback interfaces do not exist
1352 when dnsmasq is first started.
1353
1354 Tweak the PXE code to support port 4011. This should
1355 reduce broadcasts and make things more reliable when other
1356 servers are around. It also improves inter-operability
1357 with certain clients.
1358
1359 Make a pxe-service configuration with no filename or boot
1360 service type legal: this does a local boot. eg.
1361 pxe-service=x86PC, "Local boot"
1362
1363 Be more conservative in detecting "A for A"
1364 queries. Dnsmasq checks if the name in a type=A query looks
1365 like a dotted-quad IP address and answers the query itself
1366 if so, rather than forwarding it. Previously dnsmasq
1367 relied in the library function inet_addr() to convert
1368 addresses, and that will accept some things which are
1369 confusing in this context, like 1.2.3 or even just
1370 1234. Now we only do A for A processing for four decimal
1371 numbers delimited by dots.
1372
1373 A couple of tweaks to fix compilation on Solaris. Thanks
1374 to Joel Macklow for help with this.
1375
1376 Another Solaris compilation tweak, needed for Solaris
1377 2009.06. Thanks to Lee Essen for that.
1378
1379 Added extract packaging stuff from Lee Essen to
1380 contrib/Solaris10.
1381
1382 Increased the default limit on number of leases to 1000
1383 (from 150). This is mainly a defence against DoS attacks,
1384 and for the average "one for two class C networks"
1385 installation, IP address exhaustion does that just as
1386 well. Making the limit greater than the number of IP
1387 addresses available in such an installation removes a
1388 surprise which otherwise can catch people out.
1389
1390 Removed extraneous trailing space in the value of the
1391 DNSMASQ_TIME_REMAINING DNSMASQ_LEASE_LENGTH and
1392 DNSMASQ_LEASE_EXPIRES environment variables. Thanks to
1393 Gildas Le Nadan for spotting this.
1394
1395 Provide the network-id tags for a DHCP transaction to
1396 the lease-change script in the environment variable
1397 DNSMASQ_TAGS. A good suggestion from Gildas Le Nadan.
1398
1399 Add support for RFC3925 "Vendor-Identifying Vendor
1400 Options". The syntax looks like this:
1401 --dhcp-option=vi-encap:<enterprise number>, .........
1402
1403 Add support to --dhcp-match to allow matching against
1404 RFC3925 "Vendor-Identifying Vendor Classes". The syntax
1405 looks like this:
1406 --dhcp-match=tag,vi-encap<enterprise number>, <value>
1407
1408 Add some application specific code to assist in
1409 implementing the Broadband forum TR069 CPE-WAN
1410 specification. The details are in contrib/CPE-WAN/README
1411
1412 Increase the default DNS packet size limit to 4096, as
1413 recommended by RFC5625 section 4.4.3. This can be
1414 reconfigured using --edns-packet-max if needed. Thanks to
1415 Francis Dupont for pointing this out.
1416
Simon Kelley8ef5ada2010-06-03 19:42:45 +01001417 Rewrite query-ids even for TSIG signed packets, since
Simon Kelley316e2732010-01-22 20:16:09 +00001418 this is allowed by RFC5625 section 4.5.
1419
1420 Use getopt_long by default on OS X. It has been supported
1421 since version 10.3.0. Thanks to Arek Dreyer for spotting
1422 this.
1423
1424 Added up-to-date startup configuration for MacOSX/launchd
1425 in contrib/MacOSX-launchd. Thanks to Arek Dreyer for
1426 providing this.
1427
1428 Fix link error when including Dbus but excluding DHCP.
1429 Thanks to Oschtan for the bug report.
1430
1431 Updated French translation. Thanks to Gildas Le Nadan.
1432
1433 Updated Polish translation. Thanks to Jan Psota.
1434
1435 Updated Spanish translation. Thanks to Chris Chatham.
1436
Simon Kelley8ef5ada2010-06-03 19:42:45 +01001437 Fixed confusion about domains, when looking up DHCP hosts
1438 in /etc/hosts. This could cause spurious "Ignoring
1439 domain..." messages. Thanks to Fedor Kozhevnikov for
1440 finding and analysing the problem.
Simon Kelley316e2732010-01-22 20:16:09 +00001441
Simon Kelley8ef5ada2010-06-03 19:42:45 +01001442
Simon Kelley1f15b812009-10-13 17:49:32 +01001443version 2.51
1444 Add support for internationalised DNS. Non-ASCII characters
1445 in domain names found in /etc/hosts, /etc/ethers and
1446 /etc/dnsmasq.conf will be correctly handled by translation to
1447 punycode, as specified in RFC3490. This function is only
1448 available if dnsmasq is compiled with internationalisation
1449 support, and adds a dependency on GNU libidn. Without i18n
1450 support, dnsmasq continues to be compilable with just
1451 standard tools. Thanks to Yves Dorfsman for the
1452 suggestion.
1453
1454 Add two more environment variables for lease-change scripts:
1455 First, DNSMASQ_SUPPLIED_HOSTNAME; this is set to the hostname
1456 supplied by a client, even if the actual hostname used is
1457 over-ridden by dhcp-host or dhcp-ignore-names directives.
1458 Also DNSMASQ_RELAY_ADDRESS which gives the address of
1459 a DHCP relay, if used.
1460 Suggestions from Michael Rack.
1461
1462 Fix regression which broke echo of relay-agent
1463 options. Thanks to Michael Rack for spotting this.
1464
1465 Don't treat option 67 as being interchangeable with
1466 dhcp-boot parameters if it's specified as
1467 dhcp-option-force.
1468
1469 Make the code to call scripts on lease-change compile-time
1470 optional. It can be switched off by editing src/config.h
1471 or building with "make COPTS=-DNO_SCRIPT".
1472
1473 Make the TFTP server cope with filenames from Windows/DOS
1474 which use '\' as pathname separator. Thanks to Ralf for
1475 the patch.
1476
1477 Updated Polish translation. Thanks to Jan Psota.
1478
1479 Warn if an IP address is duplicated in /etc/ethers. Thanks
1480 to Felix Schwarz for pointing this out.
1481
1482 Teach --conf-dir to take an option list of file suffices
1483 which will be ignored when scanning the directory. Useful
1484 for backup files etc. Thanks to Helmut Hullen for the
1485 suggestion.
1486
1487 Add new DHCP option named tftpserver-address, which
1488 corresponds to the third argument of dhcp-boot. This
1489 allows the complete functionality of dhcp-boot to be
1490 replicated with dhcp-option. Useful when using
1491 dhcp-optsfile.
1492
1493 Test which upstream nameserver to use every 10 seconds
1494 or 50 queries and not just when a query times out and
1495 is retried. This should improve performance when there
1496 is a slow nameserver in the list. Thanks to Joe for the
1497 suggestion.
1498
1499 Don't do any PXE processing, even for clients with the
1500 correct vendorclass, unless at least one pxe-prompt or
1501 pxe-service option is given. This stops dnsmasq
1502 interfering with proxy PXE subsystems when it is just
1503 the DHCP server. Thanks to Spencer Clark for spotting this.
1504
1505 Limit the blocksize used for TFTP transfers to a value
1506 which avoids packet fragmentation, based on the MTU of the
1507 local interface. Many netboot ROMs can't cope with
1508 fragmented packets.
1509
1510 Honour dhcp-ignore configuration for PXE and proxy-PXE
1511 requests. Thanks to Niels Basjes for the bug report.
1512
1513 Updated French translation. Thanks to Gildas Le Nadan.

Simon Kelley1f15b812009-10-13 17:49:32 +01001517 Fix security problem which allowed any host permitted to
Simon Kelley77e94da2009-08-31 17:32:17 +01001518 do TFTP to possibly compromise dnsmasq by remote buffer
1519 overflow when TFTP enabled. Thanks to Core Security
1520 Technologies and Iván Arce, Pablo Hernán Jorge, Alejandro
1521 Pablo Rodriguez, Martín Coco, Alberto Soliño Testa and
1522 Pablo Annetta. This problem has Bugtraq id: 36121

1524
1525 Fix a problem which allowed a malicious TFTP client to
1526 crash dnsmasq. Thanks to Steve Grubb at Red Hat for
1527 spotting this. This problem has Bugtraq id: 36120 and
1528 CVE: 2009-2958

1532 Fix regression in 2.48 which disables the lease-change
1533 script. Thanks to Jose Luis Duran for spotting this.
1534
1535 Log TFTP "file not found" errors. These were not logged,
1536 since a normal PXELinux boot generates many of them, but
1537 the lack of the messages seems to be more confusing than
1538 routinely seeing them when there is no real error.
1539
1540 Update Spanish translation. Thanks to Chris Chatham.

Simon Kelley7622fc02009-06-04 20:32:05 +01001543version 2.48
1544 Archived the extensive, backwards, changelog to

Simon Kelley7622fc02009-06-04 20:32:05 +01001548 Fixed bug which broke binding of servers to physical
1549 interfaces when interface names were longer than four
1550 characters. Thanks to MURASE Katsunori for the patch.
Simon Kelley9e4abcb2004-01-22 19:47:41 +00001551
Simon Kelley7622fc02009-06-04 20:32:05 +01001552 Fixed netlink code to check that messages come from the
1553 correct source, and not another userspace process. Thanks
1554 to Steve Grubb for the patch.
Simon Kelley9e4abcb2004-01-22 19:47:41 +00001555
Simon Kelley7622fc02009-06-04 20:32:05 +01001556 Maintainability drive: removed bug and missing feature
1557 workarounds for some old platforms. Solaris 9, OpenBSD
1558 older than 4.1, Glibc older than 2.2, Linux 2.2.x and
1559 DBus older than 1.1.x are no longer supported.
Simon Kelley9e4abcb2004-01-22 19:47:41 +00001560
Simon Kelley7622fc02009-06-04 20:32:05 +01001561 Don't read included configuration files more than once:
1562 allows complex configuration structures without problems.
Simon Kelley9e4abcb2004-01-22 19:47:41 +00001563
Simon Kelley7622fc02009-06-04 20:32:05 +01001564 Mark log messages from the various subsystems in dnsmasq:
1565 messages from the DHCP subsystem now have the ident string
1566 "dnsmasq-dhcp" and messages from TFTP have ident
1567 "dnsmasq-tftp". Thanks to Olaf Westrik for the patch.
Simon Kelley9e4abcb2004-01-22 19:47:41 +00001568
Simon Kelley7622fc02009-06-04 20:32:05 +01001569 Fix possible infinite DHCP protocol loop when an IP
1570 address nailed to a hostname (not a MAC address) and a
1571 host sometimes provides the name, sometimes not.
Simon Kelley9e4abcb2004-01-22 19:47:41 +00001572
Simon Kelley7622fc02009-06-04 20:32:05 +01001573 Allow --addn-hosts to take a directory: all the files

Simon Kelley7622fc02009-06-04 20:32:05 +01001577 Support --bridge-interface on all platforms, not just BSD.
Simon Kelley1ab84e22004-01-29 16:48:35 +00001578
Simon Kelley7622fc02009-06-04 20:32:05 +01001579 Added support for advanced PXE functions. It's now
1580 possible to define a prompt and menu options which will
1581 be displayed when a client PXE boots. It's also possible to
1582 hand-off booting to other boot servers. Proxy-DHCP, where
1583 dnsmasq just supplies the PXE information and another DHCP
1584 server does address allocation, is also allowed. See the
1585 --pxe-prompt and --pxe-service keywords. Thanks to
1586 Alkis Georgopoulos for the suggestion and Guilherme Moro
1587 and Michael Brown for assistance.

Simon Kelley7622fc02009-06-04 20:32:05 +01001589 Improvements to DHCP logging. Thanks to Tom Metro for
1590 useful suggestions.
1591
1592 Add ability to build dnsmasq without DHCP support. To do
1593 this, edit src/config.h or build with
1594 "make COPTS=-DNO_DHCP". Thanks to Mahavir Jain for the patch.
1595
1596 Added --test command-line switch - syntax check
1597 configuration files only.

Simon Kelley7622fc02009-06-04 20:32:05 +01001599 Updated French translation. Thanks to Gildas Le Nadan.

1602version 2.47
1603 Updated French translation. Thanks to Gildas Le Nadan.
1604
1605 Fixed interface enumeration code to work on NetBSD
1606 5.0. Thanks to Roy Marples for the patch.
1607
1608 Updated config.h to use the same location for the lease
1609 file on NetBSD as the other *BSD variants. Also allow
1610 LEASEFILE and CONFFILE symbols to be overriden in CFLAGS.
1611
1612 Handle duplicate address detection on IPv6 more
1613 intelligently. In IPv6, an interface can have an address
1614 which is not usable, because it is still undergoing DAD
1615 (such addresses are marked "tentative"). Attempting to
1616 bind to an address in this state returns an error,
1617 EADDRNOTAVAIL. Previously, on getting such an error,
1618 dnsmasq would silently abandon the address, and never
1619 listen on it. Now, it retries once per second for 20
1620 seconds before generating a fatal error. 20 seconds should
1621 be long enough for any DAD process to complete, but can be
1622 adjusted in src/config.h if necessary. Thanks to Martin
1623 Krafft for the bug report.
1624
1625 Add DBus introspection. Patch from Jeremy Laine.
1626
1627 Update Dbus configuration file. Patch from Colin Walters.
1628 Fix for this bug:
1629 http://bugs.freedesktop.org/show_bug.cgi?id=18961
1630
1631 Support arbitrarily encapsulated DHCP options, suggestion
1632 and initial patch from Samium Gromoff. This is useful for
1633 (eg) gPXE, which expect all its private options to be
1634 encapsulated inside a single option 175. So, eg,
1635
1636 dhcp-option = encap:175, 190, "iscsi-client0"
1637 dhcp-option = encap:175, 191, "iscsi-client0-secret"
1638
1639 will provide iSCSI parameters to gPXE.
1640
1641 Enhance --dhcp-match to allow testing of the contents of a
1642 client-sent option, as well as its presence. This
1643 application in mind for this is RFC 4578
1644 client-architecture specifiers, but it's generally useful.
1645 Joey Korkames suggested the enhancement.
1646
1647 Move from using the IP_XMIT_IF ioctl to IP_BOUND_IF on
1648 OpenSolaris. Thanks to Bastian Machek for the heads-up.
1649
1650 No longer complain about blank lines in
1651 /etc/ethers. Thanks to Jon Nelson for the patch.
1652
1653 Fix binding of servers to physical devices, eg
1654 --server=/domain/1.2.3.4@eth0 which was broken from 2.43
1655 onwards unless --query-port=0 set. Thanks to Peter Naulls
1656 for the bug report.
1657
1658 Reply to DHCPINFORM requests even when the supplied ciaddr
1659 doesn't fall in any dhcp-range. In this case it's not
1660 possible to supply a complete configuration, but
1661 individually-configured options (eg PAC) may be useful.
1662
1663 Allow the source address of an alias to be a range:
1664 --alias=192.168.0.0,10.0.0.0,255.255.255.0 maps the whole
1665 subnet 192.168.0.0->192.168.0.255 to 10.0.0.0->10.0.0.255,
1666 as before.
1667 --alias=192.168.0.10-192.168.0.40,10.0.0.0,255.255.255.0
1668 maps only the 192.168.0.10->192.168.0.40 region. Thanks to
1669 Ib Uhrskov for the suggestion.
1670
1671 Don't dynamically allocate DHCP addresses which may break
1672 Windows. Addresses which end in .255 or .0 are broken in
1673 Windows even when using supernetting.
1674 --dhcp-range=192.168.0.1,192.168.1.254,255,255,254.0 means
1675 192.168.0.255 is a valid IP address, but not for Windows.
1676 See Microsoft KB281579. We therefore no longer allocate
1677 these addresses to avoid hard-to-diagnose problems.
1678
1679 Update Polish translation. Thanks to Jan Psota.
1680
1681 Delete the PID-file when dnsmasq shuts down. Note that by
1682 this time, dnsmasq is normally not running as root, so
1683 this will fail if the PID-file is stored in a root-owned
1684 directory; such failure is silently ignored. To take
1685 advantage of this feature, the PID-file must be stored in a
1686 directory owned and write-able by the user running
1687 dnsmasq.

1690version 2.46
1691 Allow --bootp-dynamic to take a netid tag, so that it may
1692 be selectively enabled. Thanks to Olaf Westrik for the
1693 suggestion.
1694
1695 Remove ISC-leasefile reading code. This has been
1696 deprecated for a long time, and last time I removed it, it
1697 ended up going back by request of one user. This time,
1698 it's gone for good; otherwise it would need to be
1699 re-worked to support multiple domains (see below).
1700
1701 Support DHCP clients in multiple DNS domains. This is a
1702 long-standing request. Clients are assigned to a domain
1703 based in their IP address.
1704
1705 Add --dhcp-fqdn flag, which changes behaviour if DNS names
1706 assigned to DHCP clients. When this is set, there must be
1707 a domain associated with each client, and only
1708 fully-qualified domain names are added to the DNS. The
1709 advantage is that the only the FQDN needs to be unique,
1710 so that two or more DHCP clients can share a hostname, as
1711 long as they are in different domains.
1712
1713 Set environment variable DNSMASQ_DOMAIN when invoking
1714 lease-change script. This may be useful information to
1715 have now that it's variable.
1716
1717 Tighten up data-checking code for DNS packet
1718 handling. Thanks to Steve Dodd who found certain illegal
1719 packets which could crash dnsmasq. No memory overwrite was
1720 possible, so this is not a security issue beyond the DoS
1721 potential.
1722
1723 Update example config dhcp option 47, the previous
1724 suggestion generated an illegal, zero-length,
1725 option. Thanks to Matthias Andree for finding this.
1726
1727 Rewrite hosts-file reading code to remove the limit of
1728 1024 characters per line. John C Meuser found this.
1729
1730 Create a net-id tag with the name of the interface on
1731 which the DHCP request was received.
1732
1733 Fixed minor memory leak in DBus code, thanks to Jeremy
1734 Laine for the patch.
1735
1736 Emit DBus signals as the DHCP lease database
1737 changes. Thanks to Jeremy Laine for the patch.
1738
1739 Allow for more that one MAC address in a dhcp-host
1740 line. This configuration tells dnsmasq that it's OK to
1741 abandon a DHCP lease of the fixed address to one MAC
1742 address, if another MAC address in the dhcp-host statement
1743 asks for an address. This is useful to give a fixed
1744 address to a host which has two network interfaces
1745 (say, a laptop with wired and wireless interfaces.)
1746 It's very important to ensure that only one interface
1747 at a time is up, since dnsmasq abandons the first lease
1748 and re-uses the address before the leased time has
1749 elapsed. John Gray suggested this.
1750
1751 Tweak the response to a DHCP request packet with a wrong
1752 server-id when --dhcp-authoritative is set; dnsmasq now
1753 returns a DHCPNAK, rather than silently ignoring the
1754 packet. Thanks to Chris Marget for spotting this
1755 improvement.
1756
1757 Add --cname option. This provides a limited alias
1758 function, usable for DHCP names. Thanks to AJ Weber for
1759 suggestions on this.
1760
1761 Updated contrib/webmin with latest version from Neil
1762 Fisher.
1763
1764 Updated Polish translation. Thanks to Jan Psota.
1765
1766 Correct the text names for DHCP options 64 and 65 to be
1767 "nis+-domain" and "nis+-servers".
1768
1769 Updated Spanish translation. Thanks to Chris Chatham.
1770
1771 Force re-reading of /etc/resolv.conf when an "interface
1772 up" event occurs.
1773
1774
1775version 2.45
1776 Fix total DNS failure in release 2.44 unless --min-port
1777 specified. Thanks to Steven Barth and Grant Coady for
1778 bugreport. Also reject out-of-range port spec, which could
1779 break things too: suggestion from Gilles Espinasse.
1780
1781
1782version 2.44
1783 Fix crash when unknown client attempts to renew a DHCP
1784 lease, problem introduced in version 2.43. Thanks to
1785 Carlos Carvalho for help chasing this down.
1786
1787 Fix potential crash when a host which doesn't have a lease
1788 does DHCPINFORM. Again introduced in 2.43. This bug has
1789 never been reported in the wild.
1790
1791 Fix crash in netlink code introduced in 2.43. Thanks to
1792 Jean Wolter for finding this.
1793
1794 Change implementation of min_port to work even if min-port
1795 is large.
1796
1797 Patch to enable compilation of latest Mac OS X. Thanks to
1798 David Gilman.
1799
1800 Update Spanish translation. Thanks to Christopher Chatham.
1801
1802
1803version 2.43
1804 Updated Polish translation. Thanks to Jan Psota.
1805
1806 Flag errors when configuration options are repeated
1807 illegally.
1808
1809 Further tweaks for GNU/kFreeBSD
1810
1811 Add --no-wrap to msgmerge call - provides nicer .po file
1812 format.
1813
1814 Honour lease-time spec in dhcp-host lines even for
1815 BOOTP. The user is assumed to known what they are doing in
1816 this case. (Hosts without the time spec still get infinite
1817 leases for BOOTP, over-riding the default in the
1818 dhcp-range.) Thanks to Peter Katzmann for uncovering this.
1819
1820 Fix problem matching relay-agent ids. Thanks to Michael
1821 Rack for the bug report.
1822
1823 Add --naptr-record option. Suggestion from Johan
1824 Bergquist.
1825
1826 Implement RFC 5107 server-id-override DHCP relay agent
1827 option.
1828
1829 Apply patches from Stefan Kruger for compilation on
1830 Solaris 10 under Sun studio.
1831
1832 Yet more tweaking of Linux capability code, to suppress
1833 pointless wingeing from kernel 2.6.25 and above.
1834
1835 Improve error checking during startup. Previously, some
1836 errors which occurred during startup would be worked
1837 around, with dnsmasq still starting up. Some were logged,
1838 some silent. Now, they all cause a fatal error and dnsmasq
1839 terminates with a non-zero exit code. The errors are those
1840 associated with changing uid and gid, setting process
1841 capabilities and writing the pidfile. Thanks to Uwe
1842 Gansert and the Suse security team for pointing out
1843 this improvement, and Bill Reimers for good implementation
1844 suggestions.
1845
1846 Provide NO_LARGEFILE compile option to switch off largefile
1847 support when compiling against versions of uclibc which
1848 don't support it. Thanks to Stephane Billiart for the patch.
1849
1850 Implement random source ports for interactions with
1851 upstream nameservers. New spoofing attacks have been found
1852 against nameservers which do not do this, though it is not
1853 clear if dnsmasq is vulnerable, since to doesn't implement
1854 recursion. By default dnsmasq will now use a different
1855 source port (and socket) for each query it sends
1856 upstream. This behaviour can suppressed using the
1857 --query-port option, and the old default behaviour
1858 restored using --query-port=0. Explicit source-port
1859 specifications in --server configs are still honoured.
1860
1861 Replace the random number generator, for better
1862 security. On most BSD systems, dnsmasq uses the
1863 arc4random() RNG, which is secure, but on other platforms,
1864 it relied on the C-library RNG, which may be
1865 guessable and therefore allow spoofing. This release
1866 replaces the libc RNG with the SURF RNG, from Daniel
1867 J. Berstein's DJBDNS package.
1868
1869 Don't attempt to change user or group or set capabilities
1870 if dnsmasq is run as a non-root user. Without this, the
1871 change from soft to hard errors when these fail causes
1872 problems for non-root daemons listening on high
1873 ports. Thanks to Patrick McLean for spotting this.
1874
1875 Updated French translation. Thanks to Gildas Le Nadan.
