2 Include 0.0.0.0/8 in DNS rebind checks. This range
3 translates to hosts on the local network, or, at
4 least, 0.0.0.0 accesses the local host, so could
5 be targets for DNS rebinding. See RFC 5735 section 3
6 for details. Thanks to Stephen Röttger for the bug report.

Simon Kelley63ec5d12015-07-30 20:59:07 +01008version 2.75
9 Fix reversion on 2.74 which caused 100% CPU use when a
10 dhcp-script is configured. Thanks to Adrian Davey for
11 reporting the bug and testing the fix.

13
Simon Kelley90cb2222015-07-05 21:59:10 +010014version 2.74
15 Fix reversion in 2.73 where --conf-file would attempt to
16 read the default file, rather than no file.
17
Simon Kelley362c9302015-07-06 21:48:49 +010018 Fix inotify code to handle dangling symlinks better and
19 not SEGV in some circumstances.
20
Simon Kelley13480e82015-07-16 22:23:13 +010021 DNSSEC fix. In the case of a signed CNAME generated by a
22 wildcard which pointed to an unsigned domain, the wrong
23 status would be logged, and some necessary checks omitted.

Simon Kelley00cd9d52014-10-02 21:44:21 +010026version 2.73
27 Fix crash at startup when an empty suffix is supplied to
28 --conf-dir, also trivial memory leak. Thanks to
29 Tomas Hozza for spotting this.
Simon Kelley800c5cc2014-12-15 17:50:15 +000030
31 Remove floor of 4096 on advertised EDNS0 packet size when
32 DNSSEC in use, the original rationale for this has long gone.
33 Thanks to Anders Kaseorg for spotting this.
34
Simon Kelleyad946d52014-12-15 17:52:22 +000035 Use inotify for checking on updates to /etc/resolv.conf and
36 friends under Linux. This fixes race conditions when the files are
Simon Kelley04918052015-01-26 11:23:43 +000037 updated rapidly and saves CPU by noy polling. To build
38 a binary that runs on old Linux kernels without inotify,
39 use make COPTS=-DNO_INOTIFY
Simon Kelley3ad3f3b2014-12-16 18:25:17 +000040
41 Fix breakage of --domain=<domain>,<subnet>,local - only reverse
42 queries were intercepted. THis appears to have been broken
43 since 2.69. Thanks to Josh Stone for finding the bug.
Simon Kelley47669362014-12-17 12:41:56 +000044
45 Eliminate IPv6 privacy addresses and deprecated addresses from
46 the answers given by --interface-name. Note that reverse queries
47 (ie looking for names, given addresses) are not affected.
48 Thanks to Michael Gorbach for the suggestion.
Simon Kelley094b5c32014-12-21 16:11:52 +000049
50 Fix crash in DNSSEC code with long RRs. Thanks to Marco Davids
51 for the bug report.
Glen Huang32fc6db2014-12-27 15:28:12 +000052
53 Add --ignore-address option. Ignore replies to A-record
54 queries which include the specified address. No error is
55 generated, dnsmasq simply continues to listen for another
56 reply. This is useful to defeat blocking strategies which
57 rely on quickly supplying a forged answer to a DNS
58 request for certain domains, before the correct answer can
59 arrive. Thanks to Glen Huang for the patch.
Simon Kelleyad946d52014-12-15 17:52:22 +000060
Simon Kelley97e618a2015-01-07 21:55:43 +000061 Revisit the part of DNSSEC validation which determines if an
62 unsigned answer is legit, or is in some part of the DNS
63 tree which should be signed. Dnsmasq now works from the
64 DNS root downward looking for the limit of signed
65 delegations, rather than working bottom up. This is
66 both more correct, and less likely to trip over broken
67 nameservers in the unsigned parts of the DNS tree
68 which don't respond well to DNSSEC queries.
Simon Kelley00cd9d52014-10-02 21:44:21 +010069
Simon Kelley25cf5e32015-01-09 15:53:03 +000070 Add --log-queries=extra option, which makes logs easier
71 to search automatically.
72
RinSatsuki28de3872015-01-10 15:22:21 +000073 Add --min-cache-ttl option. I've resisted this for a long
74 time, on the grounds that disbelieving TTLs is never a
75 good idea, but I've been persuaded that there are
76 sometimes reasons to do it. (Step forward, GFW).
77 To avoid misuse, there's a hard limit on the TTL
78 floor of one hour. Thansk to RinSatsuki for the patch.
Simon Kelley39341552015-01-18 22:11:10 +000079
80 Cope with multiple interfaces with the same link-local
81 address. (IPv6 addresses are scoped, so this is allowed.)
82 Thanks to Cory Benfield for help with this.
Simon Kelley5f4dc5c2015-01-20 20:51:02 +000083
84 Add --dhcp-hostsdir. This allows addition of new host
85 configurations to a running dnsmasq instance much more
86 cheaply than having dnsmasq re-read all its existing
87 configuration each time.
RinSatsuki28de3872015-01-10 15:22:21 +000088
Win King Wan61b838d2015-01-21 20:41:48 +000089 Don't reply to DHCPv6 SOLICIT messages if we're not
90 configured to do stateful DHCPv6. Thanks to Win King Wan
91 for the patch.
92
Simon Kelley6ef15b32015-01-31 22:44:26 +000093 Fix broken DNSSEC validation of ECDSA signatures.
Simon Kelleyf6e62e22015-03-01 18:17:54 +000094
95 Add --dnssec-timestamp option, which provides an automatic
Simon Kelley38440b22015-04-12 21:52:47 +010096 way to detect when the system time becomes valid after
97 boot on systems without an RTC, whilst allowing DNS
98 queries before the clock is valid so that NTP can run.
99 Thanks to Kevin Darbyshire-Bryant for developing this idea.
Stefan Tomanek30d08792015-03-31 22:32:11 +0100100
101 Add --tftp-no-fail option. Thanks to Stefan Tomanek for
102 the patch.
Simon Kelley04b0ac02015-04-06 17:19:13 +0100103
Simon Kelley38440b22015-04-12 21:52:47 +0100104 Fix crash caused by looking up servers.bind, CHAOS text
105 record, when more than about five --servers= lines are
106 in the dnsmasq config. This causes memory corruption
107 which causes a crash later. Thanks to Matt Coddington for
108 sterling work chasing this down.
109
110 Fix crash on receipt of certain malformed DNS requests.
111 Thanks to Nick Sampanis for spotting the problem.
Simon Kelley0df29f52015-04-16 15:24:52 +0100112 Note that this is could allow the dnsmasq process's
113 memory to be read by an attacker under certain
114 circumstances, so it has a CVE, CVE-2015-3294
Simon Kelley38440b22015-04-12 21:52:47 +0100115
116 Fix crash in authoritative DNS code, if a .arpa zone
117 is declared as authoritative, and then a PTR query which
118 is not to be treated as authoritative arrived. Normally,
119 directly declaring .arpa zone as authoritative is not
120 done, so this crash wouldn't be seen. Instead the
121 relevant .arpa zone should be specified as a subnet
122 in the auth-zone declaration. Thanks to Johnny S. Lee
123 for the bugreport and initial patch.
Simon Kelley04b0ac02015-04-06 17:19:13 +0100124
Simon Kelley78c61842015-04-16 15:05:30 +0100125 Fix authoritative DNS code to correctly reply to NS
126 and SOA queries for .arpa zones for which we are
127 declared authoritative by means of a subnet in auth-zone.
128 Previously we provided correct answers to PTR queries
129 in such zones (including NS and SOA) but not direct
130 NS and SOA queries. Thanks to Johnny S. Lee for
Simon Kelleya5ae1f82015-04-25 21:46:10 +0100131 pointing out the problem.
132
133 Fix logging of DHCPREPLY which should be suppressed
134 by quiet-dhcp6. Thanks to J. Pablo Abonia for
135 spotting the problem.
Simon Kelley78c61842015-04-16 15:05:30 +0100136
Simon Kelleya77cec82015-05-08 16:25:38 +0100137 Try and handle net connections with broken fragmentation
138 that lose large UDP packets. If a server times out,
139 reduce the maximum UDP packet size field in the EDNS0
140 header to 1280 bytes. If it then answers, make that
141 change permanent.
142
Simon Kelleyb059c962015-05-08 20:25:51 +0100143 Check IPv4-mapped IPv6 addresses when --stop-rebind
144 is active. Thanks to Jordan Milne for spotting this.
145
Simon Kelleyca85a282015-05-13 22:33:04 +0100146 Allow DHCPv4 options T1 and T2 to be set using --dhcp-option.
147 Thanks to Kevin Benton for patches and work on this.
148
Simon Kelley89130d92015-06-03 22:30:59 +0100149 Fix code for DHCPCONFIRM DHCPv6 messages to confirm addresses
150 in the correct subnet, even of not in dynamic address
151 allocation range. Thanks to Steve Hirsch for spotting
152 the problem.
Nicolas Cavallaric6d82c92015-06-09 20:42:20 +0100153
154 Add AddDhcpLease and DeleteDhcpLease DBus methods. Thanks
155 to Nicolas Cavallari for the patch.
Neil Jerram4918bd52015-06-10 22:23:20 +0100156
157 Allow configuration of router advertisements without the
158 "on-link" bit set. Thanks to Neil Jerram for the patch.
159
160 Extend --bridge-interface to DHCPv6 and router
161 advertisements. Thanks to Neil Jerram for the patch.

Simon Kelleyc4a09372014-06-02 20:30:07 +0100165 Add ra-advrouter mode, for RFC-3775 mobile IPv6 support.
166
167 Add support for "ipsets" in *BSD, using pf. Thanks to
168 Sven Falempim for the patch.
Simon Kelley8e9ffba2014-05-20 20:38:25 +0100169
Simon Kelleya0358e52014-06-07 13:38:48 +0100170 Fix race condition which could lock up dnsmasq when an
171 interface goes down and up rapidly. Thanks to Conrad
172 Kostecki for helping to chase this down.
Daniel Collinsc4638f92014-06-07 21:21:44 +0100173
174 Add DBus methods SetFilterWin2KOption and SetBogusPrivOption
175 Thanks to the Smoothwall project for the patch.
Simon Kelleycdb755c2014-06-18 20:52:53 +0100176
177 Fix failure to build against Nettle-3.0. Thanks to Steven
178 Barth for spotting this and finding the fix.
Simon Kelleya0358e52014-06-07 13:38:48 +0100179
Simon Kelley6d8e8ac2014-07-13 22:12:45 +0100180 When assigning existing DHCP leases to intefaces by comparing
181 networks, handle the case that two or more interfaces have the
182 same network part, but different prefix lengths (favour the
183 longer prefix length.) Thanks to Lung-Pin Chang for the
184 patch.
185
Simon Kelleyb5ea1cc2014-07-29 16:34:14 +0100186 Add a mode which detects and removes DNS forwarding loops, ie
187 a query sent to an upstream server returns as a new query to
188 dnsmasq, and would therefore be forwarded again, resulting in
189 a query which loops many times before being dropped. Upstream
190 servers which loop back are disabled and this event is logged.
191 Thanks to Smoothwall for their sponsorship of this feature.
192
Simon Kelley3e1551a2014-09-09 21:46:07 +0100193 Extend --conf-dir to allow filtering of files. So
194 --conf-dir=/etc/dnsmasq.d,\*.conf
195 will load all the files in /etc/dnsmasq.d which end in .conf
Ilya Ponetaev5bf50af2014-09-09 12:46:21 +0100196
Simon Kelley288df492014-09-18 21:48:51 +0100197 Fix bug when resulted in NXDOMAIN answers instead of NODATA in
198 some circumstances.
Simon Kelley57826492014-09-18 22:08:58 +0100199
200 Fix bug which caused dnsmasq to become unresponsive if it
201 failed to send packets due to a network interface disappearing.
202 Thanks to Niels Peen for spotting this.
Simon Kelleybf2db4b2014-09-18 22:10:46 +0100203
204 Fix problem with --local-service option on big-endian platforms
205 Thanks to Richard Genoud for the patch.

Simon Kelleyad4a8ff2015-04-09 21:48:00 +0100207
Simon Kelley9d1b22a2014-04-29 13:02:41 +0100208version 2.71
209 Subtle change to error handling to help DNSSEC validation
210 when servers fail to provide NODATA answers for
211 non-existent DS records.
212
213 Tweak code which removes DNSSEC records from answers when
214 not required. Fixes broken answers when additional section
215 has real records in it. Thanks to Marco Davids for the bug
216 report.
217
218 Fix DNSSEC validation of ANY queries. Thanks to Marco Davids
219 for spotting that too.
220
Simon Kelleyb692f232014-05-09 10:29:43 +0100221 Fix total DNS failure and 100% CPU use if cachesize set to zero,
222 regression introduced in 2.69. Thanks to James Hunt and
223 the Ubuntu crowd for assistance in fixing this.
224
Simon Kelley9d1b22a2014-04-29 13:02:41 +0100225
Simon Kelley63758382014-04-16 22:20:55 +0100226version 2.70
227 Fix crash, introduced in 2.69, on TCP request when dnsmasq
228 compiled with DNSSEC support, but running without DNSSEC
229 enabled. Thanks to Manish Sing for spotting that one.
230
Simon Kelley3b1b3e92014-04-23 15:46:05 +0100231 Fix regression which broke ipset functionality. Thanks to
232 Wang Jian for the bug report.

Simon Kelley1ee9be42013-12-09 16:50:19 +0000235version 2.69
236 Implement dynamic interface discovery on *BSD. This allows
237 the contructor: syntax to be used in dhcp-range for DHCPv6
238 on the BSD platform. Thanks to Matthias Andree for
239 valuable research on how to implement this.
240
Simon Kelley8db957d2013-12-17 15:47:10 +0000241 Fix infinite loop associated with some --bogus-nxdomain
Simon Kelley74e6b522013-12-17 21:33:53 +0000242 configs. Thanks fogobogo for the bug report.
Simon Kelley8db957d2013-12-17 15:47:10 +0000243
Simon Kelleyae762422014-01-10 18:15:16 +0000244 Fix missing RA RDNS option with configuration like
245 --dhcp-option=option6:23,[::] Thanks to Tsachi Kimeldorfer
246 for spotting the problem.
247
Simon Kelleyc3a04082014-01-11 22:18:19 +0000248 Add [fd00::] and [fe80::] as special addresses in DHCPv6
249 options, analogous to [::]. [fd00::] is replaced with the
250 actual ULA of the interface on the machine running
251 dnsmasq, [fe80::] with the link-local address.
252 Thanks to Tsachi Kimeldorfer for championing this.
253
Simon Kelley613d6c52014-02-04 11:50:11 +0000254 DNSSEC validation and caching. Dnsmasq needs to be
255 compiled with this enabled, with
256
257 make dnsmasq COPTS=-DHAVE_DNSSEC
258
259 this add dependencies on the nettle crypto library and the
260 gmp maths library. It's possible to have these linked
261 statically with
262
263 make dnsmasq COPTS='-DHAVE_DNSSEC -DHAVE_DNSSEC_STATIC'
264
Simon Kelley198d9402014-04-09 20:36:53 +0100265 which bloats the dnsmasq binary, but saves the size of
266 the shared libraries which are much bigger.
267
Simon Kelley613d6c52014-02-04 11:50:11 +0000268 To enable, DNSSEC, you will need a set of
269 trust-anchors. Now that the TLDs are signed, this can be
270 the keys for the root zone, and for convenience they are
271 included in trust-anchors.conf in the dnsmasq
272 distribution. You should of course check that these are
273 legitimate and up-to-date. So, adding
274
275 conf-file=/path/to/trust-anchors.conf
276 dnssec
Simon Kelley1ee9be42013-12-09 16:50:19 +0000277
Simon Kelley613d6c52014-02-04 11:50:11 +0000278 to your config is all thats needed to get things
279 working. The upstream nameservers have to be DNSSEC-capable
280 too, of course. Many ISP nameservers aren't, but the
281 Google public nameservers (8.8.8.8 and 8.8.4.4) are.
282 When DNSSEC is configured, dnsmasq validates any queries
283 for domains which are signed. Query results which are
284 bogus are replaced with SERVFAIL replies, and results
285 which are correctly signed have the AD bit set. In
286 addition, and just as importantly, dnsmasq supplies
287 correct DNSSEC information to clients which are doing
288 their own validation, and caches DNSKEY, DS and RRSIG
289 records, which significantly improve the performance of
290 downstream validators. Setting --log-queries will show
291 DNSSEC in action.
292
Simon Kelley198d9402014-04-09 20:36:53 +0100293 If a domain is returned from an upstream nameserver without
294 DNSSEC signature, dnsmasq by default trusts this. This
295 means that for unsigned zone (still the majority) there
296 is effectively no cost for having DNSSEC enabled. Of course
297 this allows an attacker to replace a signed record with a
298 false unsigned record. This is addressed by the
299 --dnssec-check-unsigned flag, which instructs dnsmasq
300 to prove that an unsigned record is legitimate, by finding
301 a secure proof that the zone containing the record is not
302 signed. Doing this has costs (typically one or two extra
303 upstream queries). It also has a nasty failure mode if
304 dnsmasq's upstream nameservers are not DNSSEC capable.
305 Without --dnssec-check-unsigned using such an upstream
306 server will simply result in not queries being validated;
307 with --dnssec-check-unsigned enabled and a
308 DNSSEC-ignorant upstream server, _all_ queries will fail.
309
310 Note that DNSSEC requires that the local time is valid and
311 accurate, if not then DNSSEC validation will fail. NTP
312 should be running. This presents a problem for routers
313 without a battery-backed clock. To set the time needs NTP
314 to do DNS lookups, but lookups will fail until NTP has run.
315 To address this, there's a flag, --dnssec-no-timecheck
316 which disables the time checks (only) in DNSSEC. When dnsmasq
317 is started and the clock is not synced, this flag should
318 be used. As soon as the clock is synced, SIGHUP dnsmasq.
319 The SIGHUP clears the cache of partially-validated data and
320 resets the no-timecheck flag, so that all DNSSEC checks
321 henceforward will be complete.
322
Simon Kelley613d6c52014-02-04 11:50:11 +0000323 The development of DNSSEC in dnsmasq was started by
324 Giovanni Bajo, to whom huge thanks are owed. It has been
325 supported by Comcast, whose techfund grant has allowed for
326 an invaluable period of full-time work to get it to
327 a workable state.
328
Simon Kelleyde73a492014-02-17 21:43:27 +0000329 Add --rev-server. Thanks to Dave Taht for suggesting this.
Simon Kelley7b1eae42014-02-20 13:43:28 +0000330
331 Add --servers-file. Allows dynamic update of upstream servers
332 full access to configuration.
Simon Kelleyde73a492014-02-17 21:43:27 +0000333
Simon Kelleyc8a80482014-03-05 14:29:54 +0000334 Add --local-service. Accept DNS queries only from hosts
335 whose address is on a local subnet, ie a subnet for which
336 an interface exists on the server. This option
Simon Kelleyf00690f2014-03-12 20:07:12 +0000337 only has effect if there are no --interface --except-interface,
Simon Kelleyc8a80482014-03-05 14:29:54 +0000338 --listen-address or --auth-server options. It is intended
339 to be set as a default on installation, to allow
340 unconfigured installations to be useful but also safe from
341 being used for DNS amplification attacks.
342
Simon Kelley604f7592014-03-22 19:33:43 +0000343 Fix crashes in cache_get_cname_target() when dangling CNAMEs
344 encountered. Thanks to Andy and the rt-n56u project for
345 find this and helping to chase it down.
346
Simon Kelley10068602014-04-03 21:16:40 +0100347 Fix wrong RCODE in authoritative DNS replies to PTR queries. The
348 correct answer was included, but the RCODE was set to NXDOMAIN.
349 Thanks to Craig McQueen for spotting this.
350
Simon Kelley198d9402014-04-09 20:36:53 +0100351 Make statistics available as DNS queries in the .bind TLD as
352 well as logging them.

356 Use random addresses for DHCPv6 temporary address
357 allocations, instead of algorithmically determined stable
358 addresses.
359
360 Fix bug which meant that the DHCPv6 DUID was not available
361 in DHCP script runs during the lifetime of the dnsmasq
362 process which created the DUID de-novo. Once the DUID was
363 created and stored in the lease file and dnsmasq
364 restarted, this bug disappeared.
365
366 Fix bug introduced in 2.67 which could result in erroneous

369 Fix build failures on MacOS X and openBSD.

371 Allow subnet specifications in --auth-zone to be interface
372 names as well as address literals. This makes it possible
373 to configure authoritative DNS when local address ranges
374 are dynamic and works much better than the previous
375 work-around which exempted contructed DHCP ranges from the
376 IP address filtering. As a consequence, that work-around
377 is removed. Under certain circumstances, this change wil
378 break existing configuration: if you're relying on the
379 contructed-range exception, you need to change --auth-zone
380 to specify the same interface as is used to construct your
381 DHCP ranges, probably with a trailing "/6" like this:
382 --auth-zone=example.com,eth0/6 to limit the addresses to
383 IPv6 addresses of eth0.

385 Fix problems when advertising deleted IPv6 prefixes. If
386 the prefix is deleted (rather than replaced), it doesn't
387 get advertised with zero preferred time. Thanks to Tsachi
388 for the bug report.

394 introduced in 2.67.
Simon Kelley2329bef2013-12-03 13:41:16 +0000395
396 Check the arrival interface of incoming DNS and TFTP
397 requests via IPv6, even in --bind-interfaces mode. This
398 isn't possible for IPv4 and can generate scary warnings,
399 but as it's always possible for IPv6 (the API always
400 exists) then we should do it always.
Vladislav Grishenko4c82efc2013-12-03 16:05:30 +0000401
402 Tweak the rules on prefix-lengths in --dhcp-range for
403 IPv6. The new rule is that the specified prefix length
404 must be larger than or equal to the prefix length of the
405 corresponding address on the local interface.

411 this and supplying the patch.
Simon Kelleyaa63a212013-04-22 15:01:52 +0100412
413 Repair regression in 2.64. That release stopped sending
414 lease-time information in the reply to DHCPINFORM
415 requests, on the correct grounds that it was a standards
416 violation. However, this broke the dnsmasq-specific
417 dhcp_lease_time utility. Now, DHCPINFORM returns
418 lease-time only if it's specifically requested
419 (maintaining standards) and the dhcp_lease_time utility
420 has been taught to ask for it (restoring functionality).

Simon Kelley3f2873d2013-05-14 11:28:47 +0100431
432 Handle IPv4 interface-address labels in Linux. These are
433 often used to emulate the old IP-alias addresses. Before,
434 using --interface=eth0 would service all the addresses of
435 eth0, including ones configured as aliases, which appear
436 in ifconfig as eth0:0. Now, only addresses with the label
437 eth0 are active. This is not backwards compatible: if you
438 want to continue to bind the aliases too, you need to add
439 eg. --interface=eth0:0 to the config.

Simon Kelley89500e32013-09-20 16:29:20 +0100522 Support identification of clients by MAC address in
523 DHCPv6. When using a relay, the relay must support RFC

525 connected clients. Thanks to Vladislav Grishenko
526 for prompting this feature.

528 Remove the rule for constructed DHCP ranges that the local

Simon Kelley333b2ce2013-01-07 21:46:03 +0000563version 2.66
564 Add the ability to act as an authoritative DNS
565 server. Dnsmasq can now answer queries from the wider 'net
566 with local data, as long as the correct NS records are set
567 up. Only local data is provided, to avoid creating an open
568 DNS relay. Zone transfer is supported, to allow secondary
569 servers to be configured.
570
571 Add "constructed DHCP ranges" for DHCPv6. This is intended
572 for IPv6 routers which get prefixes dynamically via prefix
573 delegation. With suitable configuration, stateful DHCPv6
574 and RA can happen automatically as prefixes are delegated
575 and then deprecated, without having to re-write the
576 dnsmasq configuration file or restart the daemon. Thanks to
577 Steven Barth for extensive testing and development work on
578 this idea.

584 Add code to make behaviour for TCP DNS requests that same
585 as for UDP requests, when a request arrives for an allowed
586 address, but via a banned interface. This change is only
587 active on Linux, since the relevant API is missing (AFAIK)
588 on other platforms. Many thanks to Tomas Hozza for
589 spotting the problem, and doing invaluable discovery of
590 the obscure and undocumented API required for the solution.

Simon Kelley3d77c042013-03-22 10:03:50 +0000598 lease-change script (and the corresponding Lua). These hold
Simon Kelleydd1721c2013-02-18 21:04:04 +0000599 information inserted into the DHCP request by a DHCP relay
600 agent. Thanks to Lakefield Communications for providing a

646
Simon Kelley12d71ed2012-08-30 15:16:41 +0100647 Finesse the check for /etc/hosts names which conflict with
648 DHCP names. Previously a name/address pair in /etc/hosts
649 which didn't match the name/address of a DHCP lease would
650 generate a warning. Now that only happesn if there is not
651 also a match. This allows multiple addresses for a name in
652 /etc/hosts with one of them assigned via DHCP.
653
Simon Kelley4d0f5b42012-09-05 23:29:30 +0100654 Fix broken vendor-option processing for BOOTP. Thanks to

719 Allow more than one --tfp-root flag. The per-interface
720 stuff is pointless without that.
721
Simon Kelley54dd3932012-06-20 11:23:38 +0100722 Add --bind-dynamic. A hybrid mode between the default and
723 --bind-interfaces which copes with dynamically created
724 interfaces.
Simon Kelley6b617c02012-06-29 21:15:42 +0100725
726 A couple of fixes to the build system for Android. Thanks
727 to Metin Kaya for the patches.
Simon Kelley54dd3932012-06-20 11:23:38 +0100728
Simon Kelley8bc4cec2012-07-03 21:04:11 +0100729 Remove the interface:<interface> argument in --dhcp-range, and
730 the interface argument to --enable-tftp. These were a
731 still-born attempt to allow automatic isolated
732 configuration by libvirt, but have never (to my knowledge)
733 been used, had very strange semantics, and have been
734 superceded by other mechanisms.
735
Simon Kelleyc4a7f902012-07-12 20:52:12 +0100736 Fixed bug logging filenames when duplicate dhcp-host
737 addresses are found. Thanks to John Hanks for the patch.
738
Simon Kelley611ebc52012-07-16 16:23:46 +0100739 Fix regression in 2.61 which broke caching of CNAME

Simon Kelley42243212012-07-20 15:19:18 +0100744 Teach DHCPv6 about the RFC 4242 information-refresh-time
745 option, and add parsing if the minutes, hours and days
746 format for options. Thanks to Francois-Xavier Le Bail for
747 the suggestion.
748
749 Allow "w" (for week) as multiplier in lease times, as well
750 as seconds, minutes, hours and days. Álvaro Gámez Machado
751 spotted the ommission.

772 Vladislav Grishenko for the patch.
773
Simon Kelleyc64b7f62012-05-18 10:19:59 +0100774 Fixed bug which broke DHCPv6/RA with prefix lengths

786 his help nailing this.
787
Simon Kelleyeabc6dd2012-03-07 20:28:20 +0000788version 2.61
789 Re-write interface discovery code on *BSD to use
790 getifaddrs. This is more portable, more straightforward,
791 and allows us to find the prefix length for IPv6
792 addresses.
793
Simon Kelley01d1b8d2012-03-28 21:37:25 +0100794 Add ra-names, ra-stateless and slaac keywords for DHCPv6.
795 Dnsmasq can now synthesise AAAA records for dual-stack
796 hosts which get IPv6 addresses via SLAAC. It is also now
797 possible to use SLAAC and stateless DHCPv6, and to
798 tell clients to use SLAAC addresses as well as DHCP ones.
799 Thanks to Dave Taht for help with this.

804 of relying on clients to send requests with the correct
805 source address, since at least one client in the wild gets
Simon Kelley8358e0f2012-04-29 21:53:09 +0100806 this wrong. Thanks to Conrad Kostecki for help tracking

810 --dhcp-authoritative is in effect. This tells clients not
811 to wait around for other DHCP servers.
812
813 Better logging of DHCPv6 options.
814
Simon Kelleye759d422012-03-16 13:18:57 +0000815 Add --host-record. Thanks to Rob Zwissler for the
816 suggestion.
817
Simon Kelleya9530962012-03-20 22:07:35 +0000818 Invoke the DHCP script with action "tftp" when a TFTP file
819 transfer completes. The size of the file, address to which
820 it was sent and complete pathname are supplied. Note that
821 version 2.60 introduced some script incompatibilties
822 associated with DHCPv6, and this is a further change. To
823 be safe, scripts should ignore unknown actions, and if
824 not IPv6-aware, should exit if the environment
825 variable DNSMASQ_IAID is set. The use-case for this is
826 to track netboot/install. Suggestion from Shantanu
827 Gadgil.
828
829 Update contrib/port-forward/dnsmasq-portforward to reflect
830 the above.
831
832 Set the environment variable DNSMASQ_LOG_DHCP when running
833 the script id --log-dhcp is in effect, so that script can
Simon Kelley52d4abf2012-03-21 21:39:48 +0000834 taylor their logging verbosity. Suggestion from Malte
835 Forkel.
836
837 Arrange that addresses specified with --listen-address
838 work even if there is no interface carrying the
839 address. This is chiefly useful for IPv4 loopback
840 addresses, where any address in 127.0.0.0/8 is a valid
841 loopback address, but normally only 127.0.0.1 appears on
842 the lo interface. Thanks to Mathieu Trudel-Lapierre for
843 the idea and initial patch.
Simon Kelleya9530962012-03-20 22:07:35 +0000844
Simon Kelley7d2b5c92012-03-23 10:00:02 +0000845 Fix crash, introduced in 2.60, when a DHCPINFORM is
846 received from a network which has no valid dhcp-range.
847 Thanks to Stephane Glondu for the bug report.
848
Simon Kelleyc8257542012-03-28 21:15:41 +0100849 Add a new DHCP lease time keyword, "deprecated" for
850 --dhcp-range. This is only valid for IPv6, and sets the
851 preffered lease time for both DHCP and RA to zero. The
852 effect is that clients can continue to use the address
853 for existing connections, but new connections will use
854 other addresses, if they exist. This makes hitless
855 renumbering at least possible.
856
857 Fix bug in address6_available() which caused DHCPv6 lease
Simon Kelley8358e0f2012-04-29 21:53:09 +0100858 aquisition to fail if more than one dhcp-range in use.

Simon Kelley1023dcb2012-04-09 18:00:08 +0100867 Don't cache data from non-recursive nameservers, since it

Simon Kelleyc72daea2012-01-05 21:33:27 +0000899 Fix DHCP when using --listen-address with an IP address
900 which is not the primary address of an interface.
901
902 Add --dhcp-client-update option.
903
904 Add Lua integration. Dnsmasq can now execute a DHCP
905 lease-change script written in Lua. This needs to be
906 enabled at compile time by setting HAVE_LUASCRIPT in
907 src/config.h or running "make COPTS=-DHAVE_LUASCRIPT"
908 Thanks to Jan-Piet Mens for the idea and proof-of-concept
909 implementation.
910
911 Tidied src/config.h to distinguish between
912 platform-dependent compile-time options which are selected
913 automatically, and builder-selectable compile time
914 options. Document the latter better, and describe how to
915 set them from the make command line.
916
917 Tidied up IPPROTO_IP/SOL_IP (and IPv6 equivalent)
918 confusion. IPPROTO_IP works everywhere now.
919
920 Set TOS on DHCP sockets, this improves things on busy
921 wireless networks. Thanks to Dave Taht for the patch.
922
Simon Kelley984d2fd2012-01-06 14:34:32 +0000923 Determine VERSION automatically based on git magic:
924 release tags or hash values.
Simon Kelleyc72daea2012-01-05 21:33:27 +0000925
Simon Kelleya2761752012-01-18 16:07:21 +0000926 Improve start-up speed when reading large hosts files
927 containing many distinct addresses.
928
929 Fix problem if dnsmasq is started without the stdin,
930 stdout and stderr file descriptors open. This can manifest
931 itself as 100% CPU use. Thanks to Chris Moore for finding
932 this.
933
Simon Kelley9bbc8872012-02-09 21:33:09 +0000934 Fix shell-scripting bug in bld/pkg-wrapper. Thanks to
935 Mark Mitchell for the patch.
936
Simon Kelley751d6f42012-02-10 15:24:51 +0000937 Allow the TFP server or boot server in --pxe-service, to
938 be a domain name instead of an IP address. This allows for
939 round-robin to multiple servers, in the same way as
940 --dhcp-boot. A good suggestion from Cristiano Cumer.
941
Simon Kelleyfdacfb02012-02-28 15:20:25 +0000942 Support BUILDDIR variable in the Makefile. Allows builds
943 for multiple archs from the same source tree with eg.
944 make BUILDDIR=linux (relative to dnsmasq tree)
945 make BUILDDIR=/tmp/openbsd (absolute path)
Simon Kelleye5ffdb92012-02-13 14:19:25 +0000946 If BUILDDIR is not set, compilation happens in the src
Simon Kelleyb36ae192012-02-13 12:54:34 +0000947 directory, as before. Suggestion from Mark Mitchell.
948
Simon Kelleyfdacfb02012-02-28 15:20:25 +0000949 Support DHCPv6. Support is there for the sort of things
950 the existing v4 server does, including tags, options,
951 static addresses and relay support. Missing is prefix
952 delegation, which is probably not required in the dnsmasq
953 niche, and an easy way to accept prefix delegations from
954 an upstream DHCPv6 server, which is. Future plans include
955 support for DHCPv6 router option and MAC address option
956 (to make selecting clients by MAC address work like IPv4).
957 These will be added as the standards mature.
958 This code has been tested, but this is the first release,
959 so don't bet the farm on it just yet. Many thanks to all
960 testers who have got it this far.
Simon Kelley1adadf52012-02-13 22:15:58 +0000961
Simon Kelleyac8540c2012-02-26 20:57:31 +0000962 Support IPv6 router advertisements. This is a
963 simple-minded implementation, aimed at providing the
964 vestigial RA needed to go alongside IPv6. Is picks up
965 configuration from the DHCPv6 conf, and should just need
966 enabling with --enable-ra.
967
Simon Kelley552af8b2012-02-29 20:10:31 +0000968 Fix long-standing wrinkle with --localise-queries that
969 could result in wrong answers when DNS packets arrive
970 via an interface other than the expected one. Thanks to
971 Lorenzo Milesi and John Hanks for spotting this one.
Simon Kelley71ee7ee2012-03-03 18:06:49 +0000972

977
Simon Kelleyc72daea2012-01-05 21:33:27 +0000978version 2.59
979 Fix regression in 2.58 which caused failure to start up
980 with some combinations of dnsmasq config and IPv6 kernel
981 network config. Thanks to Brielle Bruns for the bug
982 report.
983
984 Improve dnsmasq's behaviour when network interfaces are
985 still doing duplicate address detection (DAD). Previously,
986 dnsmasq would wait up to 20 seconds at start-up for the
987 DAD state to terminate. This is broken for bridge
988 interfaces on recent Linux kernels, which don't start DAD
989 until the bridge comes up, and so can take arbitrary
990 time. The new behaviour lets dnsmasq poll for an arbitrary
991 time whilst providing service on other interfaces. Thanks
992 to Stephen Hemminger for pointing out the problem.
Simon Kelley74c95c22011-10-19 09:33:39 +0100993
994
Simon Kelley7de060b2011-08-26 17:24:52 +0100995version 2.58
996 Provide a definition of the SA_SIZE macro where it's
997 missing. Fixes build failure on openBSD.
998
999 Don't include a zero terminator at the end of messages
1000 sent to /dev/log when /dev/log is a datagram socket.
1001 Thanks to Didier Rabound for spotting the problem.
1002
1003 Add --dhcp-sequential-ip flag, to force allocation of IP
1004 addresses in ascending order. Note that the default
1005 pseudo-random mode is in general better but some
1006 server-deployment applications need this.
1007
1008 Fix problem where a server-id of 0.0.0.0 is sent to a
1009 client when a dhcp-relay is in use if a client renews a
1010 lease after dnsmasq restart and before any clients on the
1011 subnet get a new lease. Thanks to Mike Ruiz for assistance
1012 in chasing this one down.
1013
1014 Don't return NXDOMAIN to an AAAA query if we have CNAME
1015 which points to an A record only: NODATA is the correct
1016 reply in this case. Thanks to Tom Fernandes for spotting
1017 the problem.
1018
1019 Relax the need to supply a netmask in --dhcp-range for
1020 networks which use a DHCP relay. Whilst this is still
1021 desireable, in the absence of a netmask dnsmasq will use
1022 a default based on the class (A, B, or C) of the address.
1023 This should at least remove a cause of mysterious failure
1024 for people using RFC1918 addresses and relays.
1025
1026 Add support for Linux conntrack connection marking. If
1027 enabled with --conntrack, the connection mark for incoming
1028 DNS queries will be copied to the outgoing connections
1029 used to answer those queries. This allows clever firewall
1030 and accounting stuff. Only available if dnsmasq is
1031 compiled with HAVE_CONNTRACK and adds a dependency on
1032 libnetfilter-conntrack. Thanks to Ed Wildgoose for the
1033 initial idea, testing and sponsorship of this function.
1034
1035 Provide a sane error message when someone attempts to
1036 match a tag in --dhcp-host.
1037
1038 Tweak the behaviour of --domain-needed, to avoid problems
1039 with recursive nameservers downstream of dnsmasq. The new
1040 behaviour only stops A and AAAA queries, and returns
1041 NODATA rather than NXDOMAIN replies.
1042
1043 Efficiency fix for very large DHCP configurations, thanks
1044 to James Gartrell and Mike Ruiz for help with this.
1045
1046 Allow the TFTP-server address in --dhcp-boot to be a
1047 domain-name which is looked up in /etc/hosts. This can
1048 give multiple IP addresses which are used round-robin,
1049 thus doing TFTP server load-balancing. Thanks to Sushil
1050 Agrawal for the patch.
1051
1052 When two tagged dhcp-options for a particular option
1053 number are both valid, use the one which is valid without
1054 a tag from the dhcp-range. Allows overriding of the value
1055 of a DHCP option for a particular host as well as
1056 per-network values. So
1057 --dhcp-range=set:interface1,......
1058 --dhcp-host=set:myhost,.....
1059 --dhcp-option=tag:interface1,option:nis-domain,"domain1"
1060 --dhcp-option=tag:myhost,option:nis-domain,"domain2"
1061 will set the NIS-domain to domain1 for hosts in the range, but
1062 override that to domain2 for a particular host.
1063
1064 Fix bug which resulted in truncated files and timeouts for
1065 some TFTP transfers. The bug only occurs with netascii
1066 transfers and needs an unfortunate relationship between
1067 file size, blocksize and the number of newlines in the
1068 last block before it manifests itself. Many thanks to
1069 Alkis Georgopoulos for spotting the problem and providing
1070 a comprehensive test-case.
1071
1072 Fix regression in TFTP server on *BSD platforms introduced
1073 in version 2.56, due to confusion with sockaddr
Simon Kelleyde604c12012-10-19 09:50:01 +01001074 length. Many thanks to Loic Pefferkorn for finding this.
Simon Kelley7de060b2011-08-26 17:24:52 +01001075
1076 Support scope-ids in IPv6 addresses of nameservers from
1077 /etc/resolv.conf and in --server options. Eg
1078 nameserver fe80::202:a412:4512:7bbf%eth0 or
1079 server=fe80::202:a412:4512:7bbf%eth0. Thanks to

1088 Add patches to allow build under Android.
1089
1090 Provide our own header for the DNS protocol, rather than
1091 relying on arpa/nameser.h. This has proved more or less
1092 defective over the years and the final straw is that it's
1093 effectively empty on Android.
1094

1097 wildcard.

1099 Correct wrong casts of arguments to ctype.h functions,
1100 isdigit(), isxdigit() etc. Thanks to Matthias Andree for
1101 spotting this.
1102
1103 Allow build with IDN support independently from i18n.
1104 IDN support continues to be included automatically
1105 when i18n is included.
1106 'make COPTS=-DHAVE_IDN' is the magic incantation.
1107
1108 Modify check on extraneous command line junk (added in
1109 2.56) so that it doesn't complain about extra _empty_
1110 arguments. Otherwise this breaks libvirt.
1111
1112
Simon Kelley28866e92011-02-14 20:19:14 +00001113version 2.56
1114 Add a patch to allow dnsmasq to get interface names right in a
1115 Solaris zone. Thanks to Dj Padzensky for this.
1116
1117 Improve data-type parsing heuristics so that
1118 --dhcp-option=option:domain-search,.
1119 treats the value as a string and not an IP address.
1120 Thanks to Clemens Fischer for spotting that.
1121
1122 Add IPv6 support to the TFTP server. Many thanks to Jan
1123 'RedBully' Seiffert for the patches.
1124
1125 Log DNS queries at level LOG_INFO, rather then
1126 LOG_DEBUG. This makes things consistent with DHCP
1127 logging. Thanks to Adam Pribyl for spotting the problem.
1128
1129 Ensure that dnsmasq terminates cleanly when using
1130 --syslog-async even if it cannot make a connection to the
1131 syslogd.
1132
1133 Add --add-mac option. This is to support currently
1134 experimental DNS filtering facilities. Thanks to Benjamin
1135 Petrin for the orignal patch.
1136
1137 Fix bug which meant that tags were ignored in dhcp-range
1138 configuration specifying PXE-proxy service. Thanks to
1139 Cristiano Cumer for spotting this.
1140
1141 Raise an error if there is extra junk, not part of an
1142 option, on the command line.
1143
1144 Flag a couple of log messages in cache.c as coming from
1145 the DHCP subsystem. Thanks to Olaf Westrik for the patch.
1146
1147 Omit timestamps from logs when a) logging to stderr and
1148 b) --keep-in-forground is set. The logging facility on the
1149 other end of stderr can be assumned to supply them. Thanks
1150 to John Hallam for the patch.
1151
1152 Don't complain about strings longer than 255 characters in
1153 --txt-record, just split the long strings into 255
1154 character chunks instead.
1155
1156 Fix crash on double-free. This bug can only happen when
1157 dhcp-script is in use and then only in rare circumstances
1158 triggered by high DHCP transaction rate and a slow
1159 script. Thanks to Ferenc Wagner for finding the problem.
1160
1161 Only log that a file has been sent by TFTP after the
1162 transfer has completed succesfully.
1163
1164 A good suggestion from Ferenc Wagner: extend
1165 the --domain option to allow this sort of thing:
1166 --domain=thekelleys.org.uk,192.168.0.0/24,local
1167 which automatically creates
1168 --local=/thekelleys.org.uk/
1169 --local=/0.168.192.in-addr.arpa/
1170
1171 Tighten up syntax checking of hex contants in the config
1172 file. Thanks to Fred Damen for spotting this.
1173
1174 Add dnsmasq logo/icon, contributed by Justin Swift. Many
1175 thanks for that.
1176
1177 Never cache DNS replies which have the 'cd' bit set, or
1178 which result from queries forwarded with the 'cd' bit
1179 set. The 'cd' bit instructs a DNSSEC validating server
1180 upstream to ignore signature failures and return replies
1181 anyway. Without this change it's possible to pollute the
1182 dnsmasq cache with bad data by making a query with the
1183 'cd' bit set and subsequent queries would return this data
1184 without its being marked as suspect. Thanks to Anders
1185 Kaseorg for pointing out this problem.
1186
1187 Add --proxy-dnssec flag, for compliance with RFC
1188 4035. Dnsmasq will now clear the 'ad' bit in answers returned
1189 from upstream validating nameservers unless this option is
1190 set.
1191
1192 Allow a filename of "-" for --conf-file to read
1193 stdin. Suggestion from Timothy Redaelli.
1194
1195 Rotate the order of SRV records in replies, to provide
1196 round-robin load balancing when all the priorities are
1197 equal. Thanks to Peter McKinney for the suggestion.
1198
1199 Edit
1200 contrib/MacOSX-launchd/uk.org.thekelleys.dnsmasq.plist
1201 so that it doesn't log all queries to a file by
1202 default. Thanks again to Peter McKinney.
1203
1204 By default, setting an IPv4 address for a domain but not
1205 an IPv6 address causes dnsmasq to return
1206 an NODATA reply for IPv6 (or vice-versa). So
1207 --address=/google.com/1.2.3.4 stops IPv6 queries for
1208 *google.com from being forwarded. Make it possible to
1209 override this behaviour by defining the sematics if the
1210 same domain appears in both --server and --address.
1211 In that case, the --address has priority for the address
1212 family in which is appears, but the --server has priority
1213 of the address family which doesn't appear in --adddress
1214 So:
1215 --address=/google.com/1.2.3.4
1216 --server=/google.com/#
1217 will return 1.2.3.4 for IPv4 queries for *.google.com but
1218 forward IPv6 queries to the normal upstream nameserver.
1219 Similarly when setting an IPv6 address
1220 only this will allow forwarding of IPv4 queries. Thanks to
1221 William for pointing out the need for this.
1222
1223 Allow more than one --dhcp-optsfile and --dhcp-hostsfile
1224 and make them understand directories as arguments in the
1225 same way as --addn-hosts. Suggestion from John Hanks.
1226
1227 Ignore rebinding requests for leases we don't know
1228 about. Rebind is broadcast, so we might get to overhear a
1229 request meant for another DHCP server. NAKing this is
1230 wrong. Thanks to Brad D'Hondt for assistance with this.
1231
Simon Kelley572b41e2011-02-18 18:11:18 +00001232 Fix cosmetic bug which produced strange output when

Simon Kelleyc52e1892010-06-07 22:01:39 +01001240

Simon Kelley8ef5ada2010-06-03 19:42:45 +01001253version 2.53
1254 Fix failure to compile on Debian/kFreeBSD. Thanks to
1255 Axel Beckert and Petr Salinger.
1256
1257 Fix code to avoid scary strict-aliasing warnings
1258 generated by gcc 4.4.
1259
1260 Added FAQ entry warning about DHCP failures with Vista
1261 when firewalls block 255.255.255.255.
1262
1263 Fixed bug which caused bad things to happen if a
1264 resolv.conf file which exists is subsequently removed.
1265 Thanks to Nikolai Saoukh for the patch.
1266
1267 Rationalised the DHCP tag system. Every configuration item
1268 which can set a tag does so by adding "set:<tag>" and
1269 every configuration item which is conditional on a tag is
1270 made so by "tag:<tag>". The NOT operator changes to '!',
1271 which is a bit more intuitive too. Dhcp-host directives
1272 can set more than one tag now. The old '#' NOT,
1273 "net:" prefix and no-prefixes are still honoured, so
1274 no existing config file needs to be changed, but
1275 the documentation and new-style config files should be
1276 much less confusing.
1277
1278 Added --tag-if to allow boolean operations on tags.
1279 This allows complicated logic to be clearer and more
1280 general. A great suggestion from Richard Voigt.
1281
1282 Add broadcast/unicast information to DHCP logging.
1283
1284 Allow --dhcp-broadcast to be unconditional.
1285
1286 Fixed incorrect behaviour with NOT <tag> conditionals in
1287 dhcp-options. Thanks to Max Turkewitz for assistance
1288 finding this.
1289
1290 If we send vendor-class encapsulated options based on the
1291 vendor-class supplied by the client, and no explicit
1292 vendor-class option is given, echo back the vendor-class
1293 from the client.
1294
1295 Fix bug which stopped dnsmasq from matching both a
1296 circuitid and a remoteid. Thanks to Ignacio Bravo for
1297 finding this.
1298
1299 Add --dhcp-proxy, which makes it possible to configure
1300 dnsmasq to use a DHCP relay agent as a full proxy, with
1301 all DHCP messages passing through the proxy. This is
1302 useful if the relay adds extra information to the packets
1303 it forwards, but cannot be configured with the RFC 5107
1304 server-override option.
1305
1306 Added interface:<iface name> part to dhcp-range. The
1307 semantics of this are very odd at first sight, but it
1308 allows a single line of the form
1309 dhcp-range=interface:virt0,192.168.0.4,192.168.0.200
1310 to be added to dnsmasq configuration which then supplies
1311 DHCP and DNS services to that interface, without affecting
1312 what services are supplied to other interfaces and
1313 irrespective of the existance or lack of
1314 interface=<interface>
1315 lines elsewhere in the dnsmasq configuration. The idea is
1316 that such a line can be added automatically by libvirt
1317 or equivalent systems, without disturbing any manual
1318 configuration.
1319
1320 Similarly to the above, allow --enable-tftp=<interface>
1321
1322 Allow a TFTP root to be set separately for requests via
1323 different interfaces, --tftp-root=<path>,<interface>
1324
1325 Correctly handle and log clashes between CNAMES and
1326 DNS names being given to DHCP leases. This fixes a bug
1327 which caused nonsense IP addresses to be logged. Thanks to
1328 Sergei Zhirikov for finding and analysing the problem.
1329
1330 Tweak flush_log so as to avoid leaving the log
1331 file in non-blocking mode. O_NONBLOCK is a property of the
1332 file, not the process/descriptor.
1333
1334 Fix contrib/Solaris10/create_package
1335 (/usr/man -> /usr/share/man) Thanks to Vita Batrla.
1336
1337 Fix a problem where, if a client got a lease, then went
1338 to another subnet and got another lease, then moved back,
1339 it couldn't resume the old lease, but would instead get
1340 a new address. Thanks to Leonardo Rodrigues for spotting
1341 this and testing the fix.
1342
1343 Fix weird bug which sometimes omitted certain characters
1344 from the start of quoted strings in dhcp-options. Thanks
1345 to Dayton Turner for spotting the problem.
1346
1347 Add facility to redirect some domains to the standard
1348 upstream servers: this allows something like
1349 --server=/google.com/1.2.3.4 --server=/www.google.com/#
1350 which will send queries for *.google.com to 1.2.3.4,
1351 except *www.google.com which will be forwarded as usual.
1352 Thanks to AJ Weber for prompting this addition.
1353
1354 Improve the hash-algorithm used to generate IP addresses
1355 from MAC addresses during initial DHCP address
1356 allocation. This improves performance when large numbers
1357 of hosts with similar MAC addresses all try and get an IP
1358 address at the same time. Thanks to Paul Smith for his
1359 work on this.
1360
1361 Tweak DHCP code so that --bridge-interface can be used to
1362 select which IP alias of an interface should be used for
1363 DHCP purposes on Linux. If eth0 has an alias eth0:dhcp
1364 then adding --bridge-interface=eth0:dhcp,eth0 will use
1365 the address of eth0:dhcp to determine the correct subnet
1366 for DHCP address allocation. Thanks to Pawel Golaszewski
1367 for prompting this and Eric Cooper for further testing.
1368
1369 Add --dhcp-generate-names. Suggestion by Ferenc Wagner.
1370
1371 Tweak DNS server selection algorithm when there is more
1372 than one server available for a domain, eg.
1373 --server=/mydomain/1.1.1.1
1374 --server=/mydomain/2.2.2.2
1375 Thanks to Alberto Cuesta-Canada for spotting a weakness
1376 here.
1377
1378 Add --max-ttl. Thanks to Fredrik Ringertz for the patch.
1379
1380 Allow --log-facility=- to force all logging to
1381 stderr. Suggestion from Clemens Fischer.
1382
1383 Fix regression which caused configuration like
1384 --address=/.domain.com/1.2.3.4 to be rejected. The dot to the
1385 left of the domain has been implied and not required for a
1386 long time, but it should be accepted for backward
1387 compatibility. Thanks to Andrew Burcin for spotting this.
1388
1389 Add --rebind-domain-ok and --rebind-localhost-ok.
1390 Suggestion from Clemens Fischer.
1391
1392 Log replies to queries of type TXT, when --log-queries
1393 is set.
1394
1395 Fix compiler warnings when compiled with -DNO_DHCP. Thanks
1396 to Shantanu Gadgil for the patch.
1397
1398 Updated French translation. Thanks to Gildas Le Nadan.
1399

1401
1402 Updated German translation. Thanks to Matthias Andree.
1403
1404 Added contrib/static-arp, thanks to Darren Hoo.
1405
1406 Fix corruption of the domain when a name from /etc/hosts
1407 overrides one supplied by a DHCP client. Thanks to Fedor
1408 Kozhevnikov for spotting the problem.
1409
1410 Updated Spanish translation. Thanks to Chris Chatham.
1411
1412
Simon Kelley316e2732010-01-22 20:16:09 +00001413version 2.52
1414 Work around a Linux kernel bug which insists that the
1415 length of the option passed to setsockopt must be at least
1416 sizeof(int) bytes, even if we're calling SO_BINDTODEVICE
1417 and the device name is "lo". Note that this is fixed
1418 in kernel 2.6.31, but the workaround is harmless and
1419 allows earlier kernels to be used. Also fix dnsmasq
1420 bug which reported the wrong address when this failed.
1421 Thanks to Fedor for finding this.
1422
1423 The API for IPv6 PKTINFO changed around Linux kernel
1424 2.6.14. Workaround the case where dnsmasq is compiled
1425 against newer headers, but then run on an old kernel:
1426 necessary for some *WRT distros.
1427
1428 Re-read the set of network interfaces when re-loading
1429 /etc/resolv.conf if --bind-interfaces is not set. This
1430 handles the case that loopback interfaces do not exist
1431 when dnsmasq is first started.
1432
1433 Tweak the PXE code to support port 4011. This should
1434 reduce broadcasts and make things more reliable when other
1435 servers are around. It also improves inter-operability
1436 with certain clients.
1437
1438 Make a pxe-service configuration with no filename or boot
1439 service type legal: this does a local boot. eg.
1440 pxe-service=x86PC, "Local boot"
1441
1442 Be more conservative in detecting "A for A"
1443 queries. Dnsmasq checks if the name in a type=A query looks
1444 like a dotted-quad IP address and answers the query itself
1445 if so, rather than forwarding it. Previously dnsmasq
1446 relied in the library function inet_addr() to convert
1447 addresses, and that will accept some things which are
1448 confusing in this context, like 1.2.3 or even just
1449 1234. Now we only do A for A processing for four decimal
1450 numbers delimited by dots.
1451
1452 A couple of tweaks to fix compilation on Solaris. Thanks
1453 to Joel Macklow for help with this.
1454
1455 Another Solaris compilation tweak, needed for Solaris
1456 2009.06. Thanks to Lee Essen for that.
1457
1458 Added extract packaging stuff from Lee Essen to
1459 contrib/Solaris10.
1460
1461 Increased the default limit on number of leases to 1000
1462 (from 150). This is mainly a defence against DoS attacks,
1463 and for the average "one for two class C networks"
1464 installation, IP address exhaustion does that just as
1465 well. Making the limit greater than the number of IP
1466 addresses available in such an installation removes a
1467 surprise which otherwise can catch people out.
1468
1469 Removed extraneous trailing space in the value of the
1470 DNSMASQ_TIME_REMAINING DNSMASQ_LEASE_LENGTH and
1471 DNSMASQ_LEASE_EXPIRES environment variables. Thanks to
1472 Gildas Le Nadan for spotting this.
1473
1474 Provide the network-id tags for a DHCP transaction to
1475 the lease-change script in the environment variable
1476 DNSMASQ_TAGS. A good suggestion from Gildas Le Nadan.
1477
1478 Add support for RFC3925 "Vendor-Identifying Vendor
1479 Options". The syntax looks like this:
1480 --dhcp-option=vi-encap:<enterprise number>, .........
1481
1482 Add support to --dhcp-match to allow matching against
1483 RFC3925 "Vendor-Identifying Vendor Classes". The syntax
1484 looks like this:
1485 --dhcp-match=tag,vi-encap<enterprise number>, <value>
1486
1487 Add some application specific code to assist in
1488 implementing the Broadband forum TR069 CPE-WAN
1489 specification. The details are in contrib/CPE-WAN/README
1490
1491 Increase the default DNS packet size limit to 4096, as
1492 recommended by RFC5625 section 4.4.3. This can be
1493 reconfigured using --edns-packet-max if needed. Thanks to
1494 Francis Dupont for pointing this out.
1495
Simon Kelley8ef5ada2010-06-03 19:42:45 +01001496 Rewrite query-ids even for TSIG signed packets, since
Simon Kelley316e2732010-01-22 20:16:09 +00001497 this is allowed by RFC5625 section 4.5.
1498
1499 Use getopt_long by default on OS X. It has been supported
1500 since version 10.3.0. Thanks to Arek Dreyer for spotting
1501 this.
1502
1503 Added up-to-date startup configuration for MacOSX/launchd
1504 in contrib/MacOSX-launchd. Thanks to Arek Dreyer for
1505 providing this.
1506
1507 Fix link error when including Dbus but excluding DHCP.
1508 Thanks to Oschtan for the bug report.
1509
1510 Updated French translation. Thanks to Gildas Le Nadan.
1511
1512 Updated Polish translation. Thanks to Jan Psota.

1514 Updated Spanish translation. Thanks to Chris Chatham.
1515
Simon Kelley8ef5ada2010-06-03 19:42:45 +01001516 Fixed confusion about domains, when looking up DHCP hosts
1517 in /etc/hosts. This could cause spurious "Ignoring
1518 domain..." messages. Thanks to Fedor Kozhevnikov for
1519 finding and analysing the problem.
Simon Kelley316e2732010-01-22 20:16:09 +00001520
Simon Kelley8ef5ada2010-06-03 19:42:45 +01001521
Simon Kelley1f15b812009-10-13 17:49:32 +01001522version 2.51
1523 Add support for internationalised DNS. Non-ASCII characters
1524 in domain names found in /etc/hosts, /etc/ethers and
1525 /etc/dnsmasq.conf will be correctly handled by translation to
1526 punycode, as specified in RFC3490. This function is only
1527 available if dnsmasq is compiled with internationalisation
1528 support, and adds a dependency on GNU libidn. Without i18n
1529 support, dnsmasq continues to be compilable with just
1530 standard tools. Thanks to Yves Dorfsman for the
1531 suggestion.
1532
1533 Add two more environment variables for lease-change scripts:
1534 First, DNSMASQ_SUPPLIED_HOSTNAME; this is set to the hostname
1535 supplied by a client, even if the actual hostname used is
1536 over-ridden by dhcp-host or dhcp-ignore-names directives.
1537 Also DNSMASQ_RELAY_ADDRESS which gives the address of
1538 a DHCP relay, if used.
1539 Suggestions from Michael Rack.
1540
1541 Fix regression which broke echo of relay-agent
1542 options. Thanks to Michael Rack for spotting this.
1543
1544 Don't treat option 67 as being interchangeable with
1545 dhcp-boot parameters if it's specified as
1546 dhcp-option-force.
1547
1548 Make the code to call scripts on lease-change compile-time
1549 optional. It can be switched off by editing src/config.h
1550 or building with "make COPTS=-DNO_SCRIPT".
1551
1552 Make the TFTP server cope with filenames from Windows/DOS
1553 which use '\' as pathname separator. Thanks to Ralf for
1554 the patch.
1555
1556 Updated Polish translation. Thanks to Jan Psota.
1557
1558 Warn if an IP address is duplicated in /etc/ethers. Thanks
1559 to Felix Schwarz for pointing this out.
1560
1561 Teach --conf-dir to take an option list of file suffices
1562 which will be ignored when scanning the directory. Useful
1563 for backup files etc. Thanks to Helmut Hullen for the
1564 suggestion.
1565
1566 Add new DHCP option named tftpserver-address, which
1567 corresponds to the third argument of dhcp-boot. This
1568 allows the complete functionality of dhcp-boot to be
1569 replicated with dhcp-option. Useful when using
1570 dhcp-optsfile.
1571
1572 Test which upstream nameserver to use every 10 seconds
1573 or 50 queries and not just when a query times out and
1574 is retried. This should improve performance when there
1575 is a slow nameserver in the list. Thanks to Joe for the
1576 suggestion.
1577
1578 Don't do any PXE processing, even for clients with the
1579 correct vendorclass, unless at least one pxe-prompt or
1580 pxe-service option is given. This stops dnsmasq
1581 interfering with proxy PXE subsystems when it is just
1582 the DHCP server. Thanks to Spencer Clark for spotting this.
1583
1584 Limit the blocksize used for TFTP transfers to a value
1585 which avoids packet fragmentation, based on the MTU of the
1586 local interface. Many netboot ROMs can't cope with
1587 fragmented packets.
1588
1589 Honour dhcp-ignore configuration for PXE and proxy-PXE
1590 requests. Thanks to Niels Basjes for the bug report.
1591
1592 Updated French translation. Thanks to Gildas Le Nadan.

Simon Kelley1f15b812009-10-13 17:49:32 +01001596 Fix security problem which allowed any host permitted to
Simon Kelley77e94da2009-08-31 17:32:17 +01001597 do TFTP to possibly compromise dnsmasq by remote buffer
1598 overflow when TFTP enabled. Thanks to Core Security
1599 Technologies and Iván Arce, Pablo Hernán Jorge, Alejandro
1600 Pablo Rodriguez, Martín Coco, Alberto Soliño Testa and
1601 Pablo Annetta. This problem has Bugtraq id: 36121
1602 and CVE: 2009-2957
1603
1604 Fix a problem which allowed a malicious TFTP client to
1605 crash dnsmasq. Thanks to Steve Grubb at Red Hat for
1606 spotting this. This problem has Bugtraq id: 36120 and
1607 CVE: 2009-2958
1608
1609
Simon Kelley03a97b62009-06-10 20:55:49 +01001610version 2.49
1611 Fix regression in 2.48 which disables the lease-change
1612 script. Thanks to Jose Luis Duran for spotting this.
1613
1614 Log TFTP "file not found" errors. These were not logged,
1615 since a normal PXELinux boot generates many of them, but
1616 the lack of the messages seems to be more confusing than
1617 routinely seeing them when there is no real error.
1618
1619 Update Spanish translation. Thanks to Chris Chatham.

Simon Kelley7622fc02009-06-04 20:32:05 +01001622version 2.48
1623 Archived the extensive, backwards, changelog to
1624 CHANGELOG.archive. The current changelog now runs from
1625 version 2.43 and runs conventionally.
Simon Kelley9e4abcb2004-01-22 19:47:41 +00001626
Simon Kelley7622fc02009-06-04 20:32:05 +01001627 Fixed bug which broke binding of servers to physical
1628 interfaces when interface names were longer than four
1629 characters. Thanks to MURASE Katsunori for the patch.
Simon Kelley9e4abcb2004-01-22 19:47:41 +00001630
Simon Kelley7622fc02009-06-04 20:32:05 +01001631 Fixed netlink code to check that messages come from the
1632 correct source, and not another userspace process. Thanks
1633 to Steve Grubb for the patch.
Simon Kelley9e4abcb2004-01-22 19:47:41 +00001634
Simon Kelley7622fc02009-06-04 20:32:05 +01001635 Maintainability drive: removed bug and missing feature
1636 workarounds for some old platforms. Solaris 9, OpenBSD
1637 older than 4.1, Glibc older than 2.2, Linux 2.2.x and
1638 DBus older than 1.1.x are no longer supported.
Simon Kelley9e4abcb2004-01-22 19:47:41 +00001639
Simon Kelley7622fc02009-06-04 20:32:05 +01001640 Don't read included configuration files more than once:
1641 allows complex configuration structures without problems.
Simon Kelley9e4abcb2004-01-22 19:47:41 +00001642
Simon Kelley7622fc02009-06-04 20:32:05 +01001643 Mark log messages from the various subsystems in dnsmasq:
1644 messages from the DHCP subsystem now have the ident string
1645 "dnsmasq-dhcp" and messages from TFTP have ident
1646 "dnsmasq-tftp". Thanks to Olaf Westrik for the patch.
Simon Kelley9e4abcb2004-01-22 19:47:41 +00001647
Simon Kelley7622fc02009-06-04 20:32:05 +01001648 Fix possible infinite DHCP protocol loop when an IP
1649 address nailed to a hostname (not a MAC address) and a
1650 host sometimes provides the name, sometimes not.
Simon Kelley9e4abcb2004-01-22 19:47:41 +00001651
Simon Kelley7622fc02009-06-04 20:32:05 +01001652 Allow --addn-hosts to take a directory: all the files
1653 in the directory are read. Thanks to Phil Cornelius for
1654 the suggestion.
Simon Kelley9e4abcb2004-01-22 19:47:41 +00001655
Simon Kelley7622fc02009-06-04 20:32:05 +01001656 Support --bridge-interface on all platforms, not just BSD.
Simon Kelley1ab84e22004-01-29 16:48:35 +00001657
Simon Kelley7622fc02009-06-04 20:32:05 +01001658 Added support for advanced PXE functions. It's now
1659 possible to define a prompt and menu options which will
1660 be displayed when a client PXE boots. It's also possible to
1661 hand-off booting to other boot servers. Proxy-DHCP, where
1662 dnsmasq just supplies the PXE information and another DHCP
1663 server does address allocation, is also allowed. See the
1664 --pxe-prompt and --pxe-service keywords. Thanks to
1665 Alkis Georgopoulos for the suggestion and Guilherme Moro
1666 and Michael Brown for assistance.
Simon Kelley1ab84e22004-01-29 16:48:35 +00001667
Simon Kelley7622fc02009-06-04 20:32:05 +01001668 Improvements to DHCP logging. Thanks to Tom Metro for
1669 useful suggestions.
1670
1671 Add ability to build dnsmasq without DHCP support. To do
1672 this, edit src/config.h or build with
1673 "make COPTS=-DNO_DHCP". Thanks to Mahavir Jain for the patch.
1674
1675 Added --test command-line switch - syntax check
1676 configuration files only.
Simon Kelley33820b72004-04-03 21:10:00 +01001677
Simon Kelley7622fc02009-06-04 20:32:05 +01001678 Updated French translation. Thanks to Gildas Le Nadan.
Simon Kelley9009d742008-11-14 20:04:27 +00001679
Simon Kelley73a08a22009-02-05 20:28:08 +00001680
1681version 2.47
1682 Updated French translation. Thanks to Gildas Le Nadan.
1683
1684 Fixed interface enumeration code to work on NetBSD
1685 5.0. Thanks to Roy Marples for the patch.
1686
1687 Updated config.h to use the same location for the lease
1688 file on NetBSD as the other *BSD variants. Also allow
1689 LEASEFILE and CONFFILE symbols to be overriden in CFLAGS.
1690
1691 Handle duplicate address detection on IPv6 more
1692 intelligently. In IPv6, an interface can have an address
1693 which is not usable, because it is still undergoing DAD
1694 (such addresses are marked "tentative"). Attempting to
1695 bind to an address in this state returns an error,
1696 EADDRNOTAVAIL. Previously, on getting such an error,
1697 dnsmasq would silently abandon the address, and never
1698 listen on it. Now, it retries once per second for 20
1699 seconds before generating a fatal error. 20 seconds should
1700 be long enough for any DAD process to complete, but can be
1701 adjusted in src/config.h if necessary. Thanks to Martin
1702 Krafft for the bug report.
1703
1704 Add DBus introspection. Patch from Jeremy Laine.
1705
1706 Update Dbus configuration file. Patch from Colin Walters.
1707 Fix for this bug:
1708 http://bugs.freedesktop.org/show_bug.cgi?id=18961
1709
1710 Support arbitrarily encapsulated DHCP options, suggestion
1711 and initial patch from Samium Gromoff. This is useful for
1712 (eg) gPXE, which expect all its private options to be
1713 encapsulated inside a single option 175. So, eg,
1714
1715 dhcp-option = encap:175, 190, "iscsi-client0"
1716 dhcp-option = encap:175, 191, "iscsi-client0-secret"
1717
1718 will provide iSCSI parameters to gPXE.
1719
1720 Enhance --dhcp-match to allow testing of the contents of a
1721 client-sent option, as well as its presence. This
1722 application in mind for this is RFC 4578
1723 client-architecture specifiers, but it's generally useful.
1724 Joey Korkames suggested the enhancement.
1725
1726 Move from using the IP_XMIT_IF ioctl to IP_BOUND_IF on
1727 OpenSolaris. Thanks to Bastian Machek for the heads-up.
1728
1729 No longer complain about blank lines in
1730 /etc/ethers. Thanks to Jon Nelson for the patch.
1731
1732 Fix binding of servers to physical devices, eg
1733 --server=/domain/1.2.3.4@eth0 which was broken from 2.43
1734 onwards unless --query-port=0 set. Thanks to Peter Naulls
1735 for the bug report.
1736
1737 Reply to DHCPINFORM requests even when the supplied ciaddr
1738 doesn't fall in any dhcp-range. In this case it's not
1739 possible to supply a complete configuration, but
1740 individually-configured options (eg PAC) may be useful.
1741
1742 Allow the source address of an alias to be a range:
1743 --alias=192.168.0.0,10.0.0.0,255.255.255.0 maps the whole
1744 subnet 192.168.0.0->192.168.0.255 to 10.0.0.0->10.0.0.255,
1745 as before.
1746 --alias=192.168.0.10-192.168.0.40,10.0.0.0,255.255.255.0
1747 maps only the 192.168.0.10->192.168.0.40 region. Thanks to
1748 Ib Uhrskov for the suggestion.
1749
1750 Don't dynamically allocate DHCP addresses which may break
1751 Windows. Addresses which end in .255 or .0 are broken in
1752 Windows even when using supernetting.
1753 --dhcp-range=192.168.0.1,192.168.1.254,255,255,254.0 means
1754 192.168.0.255 is a valid IP address, but not for Windows.
1755 See Microsoft KB281579. We therefore no longer allocate
1756 these addresses to avoid hard-to-diagnose problems.
1757
1758 Update Polish translation. Thanks to Jan Psota.
1759
1760 Delete the PID-file when dnsmasq shuts down. Note that by
1761 this time, dnsmasq is normally not running as root, so
1762 this will fail if the PID-file is stored in a root-owned
1763 directory; such failure is silently ignored. To take
1764 advantage of this feature, the PID-file must be stored in a
1765 directory owned and write-able by the user running
1766 dnsmasq.
Simon Kelley7622fc02009-06-04 20:32:05 +01001767
1768
1769version 2.46
1770 Allow --bootp-dynamic to take a netid tag, so that it may
1771 be selectively enabled. Thanks to Olaf Westrik for the
1772 suggestion.
1773
1774 Remove ISC-leasefile reading code. This has been
1775 deprecated for a long time, and last time I removed it, it
1776 ended up going back by request of one user. This time,
1777 it's gone for good; otherwise it would need to be
1778 re-worked to support multiple domains (see below).
1779
1780 Support DHCP clients in multiple DNS domains. This is a
1781 long-standing request. Clients are assigned to a domain
1782 based in their IP address.
1783
1784 Add --dhcp-fqdn flag, which changes behaviour if DNS names
1785 assigned to DHCP clients. When this is set, there must be
1786 a domain associated with each client, and only
1787 fully-qualified domain names are added to the DNS. The
1788 advantage is that the only the FQDN needs to be unique,
1789 so that two or more DHCP clients can share a hostname, as
1790 long as they are in different domains.
1791
1792 Set environment variable DNSMASQ_DOMAIN when invoking
1793 lease-change script. This may be useful information to
1794 have now that it's variable.
1795
1796 Tighten up data-checking code for DNS packet
1797 handling. Thanks to Steve Dodd who found certain illegal
1798 packets which could crash dnsmasq. No memory overwrite was
1799 possible, so this is not a security issue beyond the DoS
1800 potential.
1801
1802 Update example config dhcp option 47, the previous
1803 suggestion generated an illegal, zero-length,
1804 option. Thanks to Matthias Andree for finding this.
1805
1806 Rewrite hosts-file reading code to remove the limit of
1807 1024 characters per line. John C Meuser found this.
1808
1809 Create a net-id tag with the name of the interface on
1810 which the DHCP request was received.
1811
1812 Fixed minor memory leak in DBus code, thanks to Jeremy
1813 Laine for the patch.
1814
1815 Emit DBus signals as the DHCP lease database
1816 changes. Thanks to Jeremy Laine for the patch.
1817
1818 Allow for more that one MAC address in a dhcp-host
1819 line. This configuration tells dnsmasq that it's OK to
1820 abandon a DHCP lease of the fixed address to one MAC
1821 address, if another MAC address in the dhcp-host statement
1822 asks for an address. This is useful to give a fixed
1823 address to a host which has two network interfaces
1824 (say, a laptop with wired and wireless interfaces.)
1825 It's very important to ensure that only one interface
1826 at a time is up, since dnsmasq abandons the first lease
1827 and re-uses the address before the leased time has
1828 elapsed. John Gray suggested this.
1829
1830 Tweak the response to a DHCP request packet with a wrong
1831 server-id when --dhcp-authoritative is set; dnsmasq now
1832 returns a DHCPNAK, rather than silently ignoring the
1833 packet. Thanks to Chris Marget for spotting this
1834 improvement.
1835
1836 Add --cname option. This provides a limited alias
1837 function, usable for DHCP names. Thanks to AJ Weber for
1838 suggestions on this.
1839
1840 Updated contrib/webmin with latest version from Neil
1841 Fisher.
1842
1843 Updated Polish translation. Thanks to Jan Psota.
1844
1845 Correct the text names for DHCP options 64 and 65 to be
1846 "nis+-domain" and "nis+-servers".
1847
1848 Updated Spanish translation. Thanks to Chris Chatham.
1849
1850 Force re-reading of /etc/resolv.conf when an "interface
1851 up" event occurs.
1852
1853
1854version 2.45
1855 Fix total DNS failure in release 2.44 unless --min-port
1856 specified. Thanks to Steven Barth and Grant Coady for
1857 bugreport. Also reject out-of-range port spec, which could
1858 break things too: suggestion from Gilles Espinasse.
1859
1860
1861version 2.44
1862 Fix crash when unknown client attempts to renew a DHCP
1863 lease, problem introduced in version 2.43. Thanks to
1864 Carlos Carvalho for help chasing this down.
1865
1866 Fix potential crash when a host which doesn't have a lease
1867 does DHCPINFORM. Again introduced in 2.43. This bug has
1868 never been reported in the wild.
1869
1870 Fix crash in netlink code introduced in 2.43. Thanks to
1871 Jean Wolter for finding this.
1872
1873 Change implementation of min_port to work even if min-port
1874 is large.
1875
1876 Patch to enable compilation of latest Mac OS X. Thanks to
1877 David Gilman.
1878
1879 Update Spanish translation. Thanks to Christopher Chatham.
1880
1881
1882version 2.43
1883 Updated Polish translation. Thanks to Jan Psota.
1884
1885 Flag errors when configuration options are repeated
1886 illegally.
1887
1888 Further tweaks for GNU/kFreeBSD
1889
1890 Add --no-wrap to msgmerge call - provides nicer .po file
1891 format.
1892
1893 Honour lease-time spec in dhcp-host lines even for
1894 BOOTP. The user is assumed to known what they are doing in
1895 this case. (Hosts without the time spec still get infinite
1896 leases for BOOTP, over-riding the default in the
1897 dhcp-range.) Thanks to Peter Katzmann for uncovering this.
1898
1899 Fix problem matching relay-agent ids. Thanks to Michael
1900 Rack for the bug report.
1901
1902 Add --naptr-record option. Suggestion from Johan
1903 Bergquist.
1904
1905 Implement RFC 5107 server-id-override DHCP relay agent
1906 option.
1907
1908 Apply patches from Stefan Kruger for compilation on
1909 Solaris 10 under Sun studio.
1910
1911 Yet more tweaking of Linux capability code, to suppress
1912 pointless wingeing from kernel 2.6.25 and above.
1913
1914 Improve error checking during startup. Previously, some
1915 errors which occurred during startup would be worked
1916 around, with dnsmasq still starting up. Some were logged,
1917 some silent. Now, they all cause a fatal error and dnsmasq
1918 terminates with a non-zero exit code. The errors are those
1919 associated with changing uid and gid, setting process
1920 capabilities and writing the pidfile. Thanks to Uwe
1921 Gansert and the Suse security team for pointing out
1922 this improvement, and Bill Reimers for good implementation
1923 suggestions.
1924
1925 Provide NO_LARGEFILE compile option to switch off largefile
1926 support when compiling against versions of uclibc which
1927 don't support it. Thanks to Stephane Billiart for the patch.
1928
1929 Implement random source ports for interactions with
1930 upstream nameservers. New spoofing attacks have been found
1931 against nameservers which do not do this, though it is not
1932 clear if dnsmasq is vulnerable, since to doesn't implement
1933 recursion. By default dnsmasq will now use a different
1934 source port (and socket) for each query it sends
1935 upstream. This behaviour can suppressed using the
1936 --query-port option, and the old default behaviour
1937 restored using --query-port=0. Explicit source-port
1938 specifications in --server configs are still honoured.
1939
1940 Replace the random number generator, for better
1941 security. On most BSD systems, dnsmasq uses the
1942 arc4random() RNG, which is secure, but on other platforms,
1943 it relied on the C-library RNG, which may be
1944 guessable and therefore allow spoofing. This release
1945 replaces the libc RNG with the SURF RNG, from Daniel
1946 J. Berstein's DJBDNS package.
1947
1948 Don't attempt to change user or group or set capabilities
1949 if dnsmasq is run as a non-root user. Without this, the
1950 change from soft to hard errors when these fail causes
1951 problems for non-root daemons listening on high
1952 ports. Thanks to Patrick McLean for spotting this.
1953
1954 Updated French translation. Thanks to Gildas Le Nadan.
