Simon Kelleyd2aa7df2015-08-03 21:52:12 +01001version 2.76
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.
Ed Bardsleya7369be2015-08-05 21:17:18 +01007
8 Enhance --add-subnet to allow arbitrary subnet addresses.
9 Thanks to Ed Barsley for the patch.
Simon Kelley77607cb2015-09-10 23:08:43 +010010
11 Respect the --no-resolv flag in inotify code. Fixes bug
12 which caused dnsmasq to fail to start if a resolv-file
13 was a dangling symbolic link, even of --no-resolv set.
14 Thanks to Alexander Kurtz for spotting the problem.
15
Edwin Török41a8d9e2015-11-14 17:45:48 +000016 Fix crash when an A or AAAA record is defined locally,
17 in a hosts file, and an upstream server sends a reply
18 that the same name is empty. Thanks to Edwin Török for
19 the patch.
20
André Glüpkereddf3652016-01-12 12:54:17 +000021 Fix failure to correctly calculate cache-size when
22 reading a hosts-file fails. Thanks to André Glüpker
23 for the patch.
24
Simon Kelleyd05dd582016-01-19 21:23:30 +000025 Fix wrong answer to simple name query when --domain-needed
26 set, but no upstream servers configured. Dnsmasq returned
27 REFUSED, in this case, when it should be the same as when
28 upstream servers are configured - NOERROR. Thanks to
29 Allain Legacy for spotting the problem.
30
31 Return REFUSED when running out of forwarding table slots,
32 not SERVFAIL.
33
Hans Dedecker926332a2016-01-23 10:48:12 +000034 Add --max-port configuration. Thanks to Hans Dedecker for
35 the patch.
Simon Kelley1e505122016-01-25 21:29:23 +000036
37 Add --script-arp and two new functions for the dhcp-script.
38 These are "arp" and "arp-old" which announce the arrival and
39 removal of entries in the ARP or nieghbour tables.
40
41 Extend --add-mac to allow a new encoding of the MAC address
42 as base64, by configurting --add-mac=base64
Simon Kelleyfdc97e12016-02-13 17:47:17 +000043
Simon Kelley1e505122016-01-25 21:29:23 +000044 Add --add-cpe-id option.
45
Simon Kelleyfdc97e12016-02-13 17:47:17 +000046 Don't crash with divide-by-zero if an IPv6 dhcp-range
47 is declared as a whole /64.
48 (ie xx::0 to xx::ffff:ffff:ffff:ffff)
49 Thanks to Laurent Bendel for spotting this problem.
50
Simon Kelleye06e6e32016-02-24 21:26:16 +000051 Add support for a TTL parameter in --host-record and
52 --cname.
53
54 Add --dhcp-ttl option.
Simon Kelleyfdc97e12016-02-13 17:47:17 +000055
Simon Kelley63ec5d12015-07-30 20:59:07 +010056version 2.75
57 Fix reversion on 2.74 which caused 100% CPU use when a
58 dhcp-script is configured. Thanks to Adrian Davey for
59 reporting the bug and testing the fix.
60
61
Simon Kelley90cb2222015-07-05 21:59:10 +010062version 2.74
63 Fix reversion in 2.73 where --conf-file would attempt to
64 read the default file, rather than no file.
65
Simon Kelley362c9302015-07-06 21:48:49 +010066 Fix inotify code to handle dangling symlinks better and
67 not SEGV in some circumstances.
68
Simon Kelley13480e82015-07-16 22:23:13 +010069 DNSSEC fix. In the case of a signed CNAME generated by a
70 wildcard which pointed to an unsigned domain, the wrong
71 status would be logged, and some necessary checks omitted.
72
Simon Kelley362c9302015-07-06 21:48:49 +010073
Simon Kelley00cd9d52014-10-02 21:44:21 +010074version 2.73
75 Fix crash at startup when an empty suffix is supplied to
76 --conf-dir, also trivial memory leak. Thanks to
77 Tomas Hozza for spotting this.
Simon Kelley800c5cc2014-12-15 17:50:15 +000078
79 Remove floor of 4096 on advertised EDNS0 packet size when
80 DNSSEC in use, the original rationale for this has long gone.
81 Thanks to Anders Kaseorg for spotting this.
82
Simon Kelleyad946d52014-12-15 17:52:22 +000083 Use inotify for checking on updates to /etc/resolv.conf and
84 friends under Linux. This fixes race conditions when the files are
Simon Kelley04918052015-01-26 11:23:43 +000085 updated rapidly and saves CPU by noy polling. To build
86 a binary that runs on old Linux kernels without inotify,
87 use make COPTS=-DNO_INOTIFY
Simon Kelley3ad3f3b2014-12-16 18:25:17 +000088
89 Fix breakage of --domain=<domain>,<subnet>,local - only reverse
90 queries were intercepted. THis appears to have been broken
91 since 2.69. Thanks to Josh Stone for finding the bug.
Simon Kelley47669362014-12-17 12:41:56 +000092
93 Eliminate IPv6 privacy addresses and deprecated addresses from
94 the answers given by --interface-name. Note that reverse queries
95 (ie looking for names, given addresses) are not affected.
96 Thanks to Michael Gorbach for the suggestion.
Simon Kelley094b5c32014-12-21 16:11:52 +000097
98 Fix crash in DNSSEC code with long RRs. Thanks to Marco Davids
99 for the bug report.
Glen Huang32fc6db2014-12-27 15:28:12 +0000100
101 Add --ignore-address option. Ignore replies to A-record
102 queries which include the specified address. No error is
103 generated, dnsmasq simply continues to listen for another
104 reply. This is useful to defeat blocking strategies which
105 rely on quickly supplying a forged answer to a DNS
106 request for certain domains, before the correct answer can
107 arrive. Thanks to Glen Huang for the patch.
Simon Kelleyad946d52014-12-15 17:52:22 +0000108
Simon Kelley97e618a2015-01-07 21:55:43 +0000109 Revisit the part of DNSSEC validation which determines if an
110 unsigned answer is legit, or is in some part of the DNS
111 tree which should be signed. Dnsmasq now works from the
112 DNS root downward looking for the limit of signed
113 delegations, rather than working bottom up. This is
114 both more correct, and less likely to trip over broken
115 nameservers in the unsigned parts of the DNS tree
116 which don't respond well to DNSSEC queries.
Simon Kelley00cd9d52014-10-02 21:44:21 +0100117
Simon Kelley25cf5e32015-01-09 15:53:03 +0000118 Add --log-queries=extra option, which makes logs easier
119 to search automatically.
120
RinSatsuki28de3872015-01-10 15:22:21 +0000121 Add --min-cache-ttl option. I've resisted this for a long
122 time, on the grounds that disbelieving TTLs is never a
123 good idea, but I've been persuaded that there are
124 sometimes reasons to do it. (Step forward, GFW).
125 To avoid misuse, there's a hard limit on the TTL
126 floor of one hour. Thansk to RinSatsuki for the patch.
Simon Kelley39341552015-01-18 22:11:10 +0000127
128 Cope with multiple interfaces with the same link-local
129 address. (IPv6 addresses are scoped, so this is allowed.)
130 Thanks to Cory Benfield for help with this.
Simon Kelley5f4dc5c2015-01-20 20:51:02 +0000131
132 Add --dhcp-hostsdir. This allows addition of new host
133 configurations to a running dnsmasq instance much more
134 cheaply than having dnsmasq re-read all its existing
135 configuration each time.
RinSatsuki28de3872015-01-10 15:22:21 +0000136
Win King Wan61b838d2015-01-21 20:41:48 +0000137 Don't reply to DHCPv6 SOLICIT messages if we're not
138 configured to do stateful DHCPv6. Thanks to Win King Wan
139 for the patch.
140
Simon Kelley6ef15b32015-01-31 22:44:26 +0000141 Fix broken DNSSEC validation of ECDSA signatures.
Simon Kelleyf6e62e22015-03-01 18:17:54 +0000142
143 Add --dnssec-timestamp option, which provides an automatic
Simon Kelley38440b22015-04-12 21:52:47 +0100144 way to detect when the system time becomes valid after
145 boot on systems without an RTC, whilst allowing DNS
146 queries before the clock is valid so that NTP can run.
147 Thanks to Kevin Darbyshire-Bryant for developing this idea.
Stefan Tomanek30d08792015-03-31 22:32:11 +0100148
149 Add --tftp-no-fail option. Thanks to Stefan Tomanek for
150 the patch.
Simon Kelley04b0ac02015-04-06 17:19:13 +0100151
Simon Kelley38440b22015-04-12 21:52:47 +0100152 Fix crash caused by looking up servers.bind, CHAOS text
153 record, when more than about five --servers= lines are
154 in the dnsmasq config. This causes memory corruption
155 which causes a crash later. Thanks to Matt Coddington for
156 sterling work chasing this down.
157
158 Fix crash on receipt of certain malformed DNS requests.
159 Thanks to Nick Sampanis for spotting the problem.
Simon Kelley0df29f52015-04-16 15:24:52 +0100160 Note that this is could allow the dnsmasq process's
161 memory to be read by an attacker under certain
162 circumstances, so it has a CVE, CVE-2015-3294
Simon Kelley38440b22015-04-12 21:52:47 +0100163
164 Fix crash in authoritative DNS code, if a .arpa zone
165 is declared as authoritative, and then a PTR query which
166 is not to be treated as authoritative arrived. Normally,
167 directly declaring .arpa zone as authoritative is not
168 done, so this crash wouldn't be seen. Instead the
169 relevant .arpa zone should be specified as a subnet
170 in the auth-zone declaration. Thanks to Johnny S. Lee
171 for the bugreport and initial patch.
Simon Kelley04b0ac02015-04-06 17:19:13 +0100172
Simon Kelley78c61842015-04-16 15:05:30 +0100173 Fix authoritative DNS code to correctly reply to NS
174 and SOA queries for .arpa zones for which we are
175 declared authoritative by means of a subnet in auth-zone.
176 Previously we provided correct answers to PTR queries
177 in such zones (including NS and SOA) but not direct
178 NS and SOA queries. Thanks to Johnny S. Lee for
Simon Kelleya5ae1f82015-04-25 21:46:10 +0100179 pointing out the problem.
180
181 Fix logging of DHCPREPLY which should be suppressed
182 by quiet-dhcp6. Thanks to J. Pablo Abonia for
183 spotting the problem.
Simon Kelley78c61842015-04-16 15:05:30 +0100184
Simon Kelleya77cec82015-05-08 16:25:38 +0100185 Try and handle net connections with broken fragmentation
186 that lose large UDP packets. If a server times out,
187 reduce the maximum UDP packet size field in the EDNS0
188 header to 1280 bytes. If it then answers, make that
189 change permanent.
190
Simon Kelleyb059c962015-05-08 20:25:51 +0100191 Check IPv4-mapped IPv6 addresses when --stop-rebind
192 is active. Thanks to Jordan Milne for spotting this.
193
Simon Kelleyca85a282015-05-13 22:33:04 +0100194 Allow DHCPv4 options T1 and T2 to be set using --dhcp-option.
195 Thanks to Kevin Benton for patches and work on this.
196
Simon Kelley89130d92015-06-03 22:30:59 +0100197 Fix code for DHCPCONFIRM DHCPv6 messages to confirm addresses
198 in the correct subnet, even of not in dynamic address
199 allocation range. Thanks to Steve Hirsch for spotting
200 the problem.
Nicolas Cavallaric6d82c92015-06-09 20:42:20 +0100201
202 Add AddDhcpLease and DeleteDhcpLease DBus methods. Thanks
203 to Nicolas Cavallari for the patch.
Neil Jerram4918bd52015-06-10 22:23:20 +0100204
205 Allow configuration of router advertisements without the
206 "on-link" bit set. Thanks to Neil Jerram for the patch.
207
208 Extend --bridge-interface to DHCPv6 and router
209 advertisements. Thanks to Neil Jerram for the patch.
Simon Kelley89130d92015-06-03 22:30:59 +0100210

Simon Kelley8e9ffba2014-05-20 20:38:25 +0100212version 2.72
Simon Kelleyc4a09372014-06-02 20:30:07 +0100213 Add ra-advrouter mode, for RFC-3775 mobile IPv6 support.
214
215 Add support for "ipsets" in *BSD, using pf. Thanks to
216 Sven Falempim for the patch.
Simon Kelley8e9ffba2014-05-20 20:38:25 +0100217
Simon Kelleya0358e52014-06-07 13:38:48 +0100218 Fix race condition which could lock up dnsmasq when an
219 interface goes down and up rapidly. Thanks to Conrad
220 Kostecki for helping to chase this down.
Daniel Collinsc4638f92014-06-07 21:21:44 +0100221
222 Add DBus methods SetFilterWin2KOption and SetBogusPrivOption
223 Thanks to the Smoothwall project for the patch.
Simon Kelleycdb755c2014-06-18 20:52:53 +0100224
225 Fix failure to build against Nettle-3.0. Thanks to Steven
226 Barth for spotting this and finding the fix.
Simon Kelleya0358e52014-06-07 13:38:48 +0100227
Simon Kelley6d8e8ac2014-07-13 22:12:45 +0100228 When assigning existing DHCP leases to intefaces by comparing
229 networks, handle the case that two or more interfaces have the
230 same network part, but different prefix lengths (favour the
231 longer prefix length.) Thanks to Lung-Pin Chang for the
232 patch.
233
Simon Kelleyb5ea1cc2014-07-29 16:34:14 +0100234 Add a mode which detects and removes DNS forwarding loops, ie
235 a query sent to an upstream server returns as a new query to
236 dnsmasq, and would therefore be forwarded again, resulting in
237 a query which loops many times before being dropped. Upstream
238 servers which loop back are disabled and this event is logged.
239 Thanks to Smoothwall for their sponsorship of this feature.
240
Simon Kelley3e1551a2014-09-09 21:46:07 +0100241 Extend --conf-dir to allow filtering of files. So
242 --conf-dir=/etc/dnsmasq.d,\*.conf
243 will load all the files in /etc/dnsmasq.d which end in .conf
Ilya Ponetaev5bf50af2014-09-09 12:46:21 +0100244
Simon Kelley288df492014-09-18 21:48:51 +0100245 Fix bug when resulted in NXDOMAIN answers instead of NODATA in
246 some circumstances.
Simon Kelley57826492014-09-18 22:08:58 +0100247
248 Fix bug which caused dnsmasq to become unresponsive if it
249 failed to send packets due to a network interface disappearing.
250 Thanks to Niels Peen for spotting this.
Simon Kelleybf2db4b2014-09-18 22:10:46 +0100251
252 Fix problem with --local-service option on big-endian platforms
253 Thanks to Richard Genoud for the patch.
254
Simon Kelleyad4a8ff2015-04-09 21:48:00 +0100255
Simon Kelley9d1b22a2014-04-29 13:02:41 +0100256version 2.71
257 Subtle change to error handling to help DNSSEC validation
258 when servers fail to provide NODATA answers for
259 non-existent DS records.
260
261 Tweak code which removes DNSSEC records from answers when
262 not required. Fixes broken answers when additional section
263 has real records in it. Thanks to Marco Davids for the bug
264 report.
265
266 Fix DNSSEC validation of ANY queries. Thanks to Marco Davids
267 for spotting that too.
268
Simon Kelleyb692f232014-05-09 10:29:43 +0100269 Fix total DNS failure and 100% CPU use if cachesize set to zero,
270 regression introduced in 2.69. Thanks to James Hunt and
271 the Ubuntu crowd for assistance in fixing this.
272
Simon Kelley9d1b22a2014-04-29 13:02:41 +0100273
Simon Kelley63758382014-04-16 22:20:55 +0100274version 2.70
275 Fix crash, introduced in 2.69, on TCP request when dnsmasq
276 compiled with DNSSEC support, but running without DNSSEC
277 enabled. Thanks to Manish Sing for spotting that one.
278
Simon Kelley3b1b3e92014-04-23 15:46:05 +0100279 Fix regression which broke ipset functionality. Thanks to
280 Wang Jian for the bug report.

Simon Kelley63758382014-04-16 22:20:55 +0100282
Simon Kelley1ee9be42013-12-09 16:50:19 +0000283version 2.69
284 Implement dynamic interface discovery on *BSD. This allows
285 the contructor: syntax to be used in dhcp-range for DHCPv6
286 on the BSD platform. Thanks to Matthias Andree for
287 valuable research on how to implement this.
288
Simon Kelley8db957d2013-12-17 15:47:10 +0000289 Fix infinite loop associated with some --bogus-nxdomain
Simon Kelley74e6b522013-12-17 21:33:53 +0000290 configs. Thanks fogobogo for the bug report.
Simon Kelley8db957d2013-12-17 15:47:10 +0000291
Simon Kelleyae762422014-01-10 18:15:16 +0000292 Fix missing RA RDNS option with configuration like
293 --dhcp-option=option6:23,[::] Thanks to Tsachi Kimeldorfer
294 for spotting the problem.
295
Simon Kelleyc3a04082014-01-11 22:18:19 +0000296 Add [fd00::] and [fe80::] as special addresses in DHCPv6
297 options, analogous to [::]. [fd00::] is replaced with the
298 actual ULA of the interface on the machine running
299 dnsmasq, [fe80::] with the link-local address.
300 Thanks to Tsachi Kimeldorfer for championing this.
301
Simon Kelley613d6c52014-02-04 11:50:11 +0000302 DNSSEC validation and caching. Dnsmasq needs to be
303 compiled with this enabled, with
304
305 make dnsmasq COPTS=-DHAVE_DNSSEC
306
307 this add dependencies on the nettle crypto library and the
308 gmp maths library. It's possible to have these linked
309 statically with
310
311 make dnsmasq COPTS='-DHAVE_DNSSEC -DHAVE_DNSSEC_STATIC'
312
Simon Kelley198d9402014-04-09 20:36:53 +0100313 which bloats the dnsmasq binary, but saves the size of
314 the shared libraries which are much bigger.
315
Simon Kelley613d6c52014-02-04 11:50:11 +0000316 To enable, DNSSEC, you will need a set of
317 trust-anchors. Now that the TLDs are signed, this can be
318 the keys for the root zone, and for convenience they are
319 included in trust-anchors.conf in the dnsmasq
320 distribution. You should of course check that these are
321 legitimate and up-to-date. So, adding
322
323 conf-file=/path/to/trust-anchors.conf
324 dnssec
Simon Kelley1ee9be42013-12-09 16:50:19 +0000325
Simon Kelley613d6c52014-02-04 11:50:11 +0000326 to your config is all thats needed to get things
327 working. The upstream nameservers have to be DNSSEC-capable
328 too, of course. Many ISP nameservers aren't, but the
329 Google public nameservers (8.8.8.8 and 8.8.4.4) are.
330 When DNSSEC is configured, dnsmasq validates any queries
331 for domains which are signed. Query results which are
332 bogus are replaced with SERVFAIL replies, and results
333 which are correctly signed have the AD bit set. In
334 addition, and just as importantly, dnsmasq supplies
335 correct DNSSEC information to clients which are doing
336 their own validation, and caches DNSKEY, DS and RRSIG
337 records, which significantly improve the performance of
338 downstream validators. Setting --log-queries will show
339 DNSSEC in action.
340
Simon Kelley198d9402014-04-09 20:36:53 +0100341 If a domain is returned from an upstream nameserver without
342 DNSSEC signature, dnsmasq by default trusts this. This
343 means that for unsigned zone (still the majority) there
344 is effectively no cost for having DNSSEC enabled. Of course
345 this allows an attacker to replace a signed record with a
346 false unsigned record. This is addressed by the
347 --dnssec-check-unsigned flag, which instructs dnsmasq
348 to prove that an unsigned record is legitimate, by finding
349 a secure proof that the zone containing the record is not
350 signed. Doing this has costs (typically one or two extra
351 upstream queries). It also has a nasty failure mode if
352 dnsmasq's upstream nameservers are not DNSSEC capable.
353 Without --dnssec-check-unsigned using such an upstream
354 server will simply result in not queries being validated;
355 with --dnssec-check-unsigned enabled and a
356 DNSSEC-ignorant upstream server, _all_ queries will fail.
357
358 Note that DNSSEC requires that the local time is valid and
359 accurate, if not then DNSSEC validation will fail. NTP
360 should be running. This presents a problem for routers
361 without a battery-backed clock. To set the time needs NTP
362 to do DNS lookups, but lookups will fail until NTP has run.
363 To address this, there's a flag, --dnssec-no-timecheck
364 which disables the time checks (only) in DNSSEC. When dnsmasq
365 is started and the clock is not synced, this flag should
366 be used. As soon as the clock is synced, SIGHUP dnsmasq.
367 The SIGHUP clears the cache of partially-validated data and
368 resets the no-timecheck flag, so that all DNSSEC checks
369 henceforward will be complete.

Simon Kelley613d6c52014-02-04 11:50:11 +0000371 The development of DNSSEC in dnsmasq was started by
372 Giovanni Bajo, to whom huge thanks are owed. It has been
373 supported by Comcast, whose techfund grant has allowed for
374 an invaluable period of full-time work to get it to
375 a workable state.
376
Simon Kelleyde73a492014-02-17 21:43:27 +0000377 Add --rev-server. Thanks to Dave Taht for suggesting this.
Simon Kelley7b1eae42014-02-20 13:43:28 +0000378
379 Add --servers-file. Allows dynamic update of upstream servers
380 full access to configuration.
Simon Kelleyde73a492014-02-17 21:43:27 +0000381
Simon Kelleyc8a80482014-03-05 14:29:54 +0000382 Add --local-service. Accept DNS queries only from hosts
383 whose address is on a local subnet, ie a subnet for which
384 an interface exists on the server. This option
Simon Kelleyf00690f2014-03-12 20:07:12 +0000385 only has effect if there are no --interface --except-interface,
Simon Kelleyc8a80482014-03-05 14:29:54 +0000386 --listen-address or --auth-server options. It is intended
387 to be set as a default on installation, to allow
388 unconfigured installations to be useful but also safe from
389 being used for DNS amplification attacks.
390
Simon Kelley604f7592014-03-22 19:33:43 +0000391 Fix crashes in cache_get_cname_target() when dangling CNAMEs
392 encountered. Thanks to Andy and the rt-n56u project for
393 find this and helping to chase it down.
394
Simon Kelley10068602014-04-03 21:16:40 +0100395 Fix wrong RCODE in authoritative DNS replies to PTR queries. The
396 correct answer was included, but the RCODE was set to NXDOMAIN.
397 Thanks to Craig McQueen for spotting this.
398

404 Use random addresses for DHCPv6 temporary address
405 allocations, instead of algorithmically determined stable
406 addresses.
407
408 Fix bug which meant that the DHCPv6 DUID was not available
409 in DHCP script runs during the lifetime of the dnsmasq
410 process which created the DUID de-novo. Once the DUID was
411 created and stored in the lease file and dnsmasq
412 restarted, this bug disappeared.
413
414 Fix bug introduced in 2.67 which could result in erroneous
415 NXDOMAIN returns to CNAME queries.
416
417 Fix build failures on MacOS X and openBSD.
418
419 Allow subnet specifications in --auth-zone to be interface
420 names as well as address literals. This makes it possible
421 to configure authoritative DNS when local address ranges
422 are dynamic and works much better than the previous
423 work-around which exempted contructed DHCP ranges from the
424 IP address filtering. As a consequence, that work-around
425 is removed. Under certain circumstances, this change wil
426 break existing configuration: if you're relying on the
427 contructed-range exception, you need to change --auth-zone
428 to specify the same interface as is used to construct your
429 DHCP ranges, probably with a trailing "/6" like this:
430 --auth-zone=example.com,eth0/6 to limit the addresses to
431 IPv6 addresses of eth0.
Simon Kelleydd9d9ce2013-11-15 11:24:00 +0000432
433 Fix problems when advertising deleted IPv6 prefixes. If
434 the prefix is deleted (rather than replaced), it doesn't
435 get advertised with zero preferred time. Thanks to Tsachi
436 for the bug report.
Simon Kelley25439062013-11-25 21:14:51 +0000437

442 introduced in 2.67.
Simon Kelley2329bef2013-12-03 13:41:16 +0000443
444 Check the arrival interface of incoming DNS and TFTP
445 requests via IPv6, even in --bind-interfaces mode. This
446 isn't possible for IPv4 and can generate scary warnings,
447 but as it's always possible for IPv6 (the API always
448 exists) then we should do it always.
Vladislav Grishenko4c82efc2013-12-03 16:05:30 +0000449
450 Tweak the rules on prefix-lengths in --dhcp-range for
451 IPv6. The new rule is that the specified prefix length
452 must be larger than or equal to the prefix length of the
453 corresponding address on the local interface.

459 this and supplying the patch.
Simon Kelleyaa63a212013-04-22 15:01:52 +0100460
461 Repair regression in 2.64. That release stopped sending
462 lease-time information in the reply to DHCPINFORM
463 requests, on the correct grounds that it was a standards
464 violation. However, this broke the dnsmasq-specific
465 dhcp_lease_time utility. Now, DHCPINFORM returns
466 lease-time only if it's specifically requested
467 (maintaining standards) and the dhcp_lease_time utility
468 has been taught to ask for it (restoring functionality).
Simon Kelley86e92f92013-04-23 11:31:39 +0100469

Simon Kelley3f2873d2013-05-14 11:28:47 +0100479
480 Handle IPv4 interface-address labels in Linux. These are
481 often used to emulate the old IP-alias addresses. Before,
482 using --interface=eth0 would service all the addresses of
483 eth0, including ones configured as aliases, which appear
484 in ifconfig as eth0:0. Now, only addresses with the label
485 eth0 are active. This is not backwards compatible: if you
486 want to continue to bind the aliases too, you need to add
487 eg. --interface=eth0:0 to the config.

Simon Kelleye2ba0df2013-05-31 17:04:25 +0100508 If wildcards are used in --interface, don't assume that
509 there will only ever be one available interface for DHCP
510 just because there is one at start-up. More may appear, so

Simon Kelleyef1a94a2013-07-26 13:59:03 +0100532 When the address which triggered the construction of an
533 advertised IPv6 prefix disappears, continue to advertise
534 the prefix for up to 2 hours, with the preferred lifetime
535 set to zero. This satisfies RFC 6204 4.3 L-13 and makes
536 things work better if a prefix disappears without being
537 deprecated first. Thanks to Uwe Schindler for persuasively
538 arguing for this.

Simon Kelley333b2ce2013-01-07 21:46:03 +0000611version 2.66
612 Add the ability to act as an authoritative DNS
613 server. Dnsmasq can now answer queries from the wider 'net
614 with local data, as long as the correct NS records are set
615 up. Only local data is provided, to avoid creating an open
616 DNS relay. Zone transfer is supported, to allow secondary
617 servers to be configured.
618
619 Add "constructed DHCP ranges" for DHCPv6. This is intended
620 for IPv6 routers which get prefixes dynamically via prefix
621 delegation. With suitable configuration, stateful DHCPv6
622 and RA can happen automatically as prefixes are delegated
623 and then deprecated, without having to re-write the
624 dnsmasq configuration file or restart the daemon. Thanks to
625 Steven Barth for extensive testing and development work on
626 this idea.

632 Add code to make behaviour for TCP DNS requests that same
633 as for UDP requests, when a request arrives for an allowed
634 address, but via a banned interface. This change is only
635 active on Linux, since the relevant API is missing (AFAIK)

694
Simon Kelley12d71ed2012-08-30 15:16:41 +0100695 Finesse the check for /etc/hosts names which conflict with

697 which didn't match the name/address of a DHCP lease would
698 generate a warning. Now that only happesn if there is not

Simon Kelley1d860412012-09-20 20:48:04 +0100720 Add --max-cache-ttl option. Thanks to Dennis Kaarsemaker
721 for the patch.
722
Simon Kelleye4807d82012-09-27 21:52:26 +0100723 Fix breakage of --host-record parsing, resulting in
724 infinte loop at startup. Regression in 2.63. Thanks to
725 Haim Gelfenbeyn for spotting this.
726
Simon Kelley20223102012-10-15 10:41:17 +0100727 Set SO_REUSEADDRESS and SO_V6ONLY options on the DHCPv6
728 socket, this allows multiple instances of dnsmasq on a
729 single machine, in the same way as for DHCPv4. Thanks to
730 Gene Czarcinski and Vladislav Grishenko for work on this.
731
Simon Kelleybe6cfb42012-10-16 20:38:31 +0100732 Fix DHCPv6 to do access control correctly when it's
733 configured with --listen-address. Thanks to
734 Gene Czarcinski for sorting this out.
735
Simon Kelley819ff4d2012-10-21 18:25:12 +0100736 Add a "wildcard" dhcp-range which works for any IPv6
737 subnet, --dhcp-range=::,static Useful for Stateless
738 DHCPv6. Thanks to Vladislav Grishenko for the patch.
739
Simon Kelleyd1a59752012-11-05 16:50:30 +0000740 Don't include lease-time in DHCPACK replies to DHCPINFORM
741 queries, since RFC-2131 says we shouldn't. Thanks to
742 Wouter Ibens for pointing this out.
Simon Kelley8e4b8792012-11-14 14:12:56 +0000743
744 Makefile tweak to do dependency checking on header files.
745 Thanks to Johan Peeters for the patch.
Simon Kelleyd89fb4e2012-12-01 21:21:13 +0000746
747 Check interface for outgoing unsolicited router
748 advertisements, rather than relying on interface address
749 configuration. Thanks to Gene Czarinski for the patch.
Simon Kelley29d28dd2012-12-03 14:05:59 +0000750
751 Handle better attempts to transmit on interfaces which are
752 still doing DAD, and specifically do not just transmit
753 without setting source address and interface, since this
754 can cause very puzzling effects when a router
755 advertisement goes astray. Thanks again to Gene Czarinski.
756
757 Get RA timers right when there is more than one
758 dhcp-range on a subnet.

762 Do duplicate dhcp-host address check in --test mode.
763
Simon Kelley8b3ae2f2012-06-13 13:43:49 +0100764 Check that tftp-root directories are accessible before
765 start-up. Thanks to Daniel Veillard for the initial patch.
766
767 Allow more than one --tfp-root flag. The per-interface
768 stuff is pointless without that.
769
Simon Kelley54dd3932012-06-20 11:23:38 +0100770 Add --bind-dynamic. A hybrid mode between the default and
771 --bind-interfaces which copes with dynamically created
772 interfaces.
Simon Kelley6b617c02012-06-29 21:15:42 +0100773
774 A couple of fixes to the build system for Android. Thanks
775 to Metin Kaya for the patches.
Simon Kelley54dd3932012-06-20 11:23:38 +0100776
Simon Kelley8bc4cec2012-07-03 21:04:11 +0100777 Remove the interface:<interface> argument in --dhcp-range, and
778 the interface argument to --enable-tftp. These were a
779 still-born attempt to allow automatic isolated
780 configuration by libvirt, but have never (to my knowledge)
781 been used, had very strange semantics, and have been
782 superceded by other mechanisms.
783
Simon Kelleyc4a7f902012-07-12 20:52:12 +0100784 Fixed bug logging filenames when duplicate dhcp-host
785 addresses are found. Thanks to John Hanks for the patch.
786
Simon Kelley611ebc52012-07-16 16:23:46 +0100787 Fix regression in 2.61 which broke caching of CNAME
788 chains. Thanks to Atul Gupta for the bug report.
789
Simon Kelleyb2714462012-07-17 12:09:26 +0100790 Allow the target of a --cname flag to be another --cname.
Simon Kelley611ebc52012-07-16 16:23:46 +0100791
Simon Kelley42243212012-07-20 15:19:18 +0100792 Teach DHCPv6 about the RFC 4242 information-refresh-time
793 option, and add parsing if the minutes, hours and days
794 format for options. Thanks to Francois-Xavier Le Bail for
795 the suggestion.
796
797 Allow "w" (for week) as multiplier in lease times, as well
798 as seconds, minutes, hours and days. Álvaro Gámez Machado
799 spotted the ommission.

Simon Kelleyad094272012-08-10 17:10:54 +0100803 Allow a DBus service name to be given with --enable-dbus
804 which overrides the default,

Simon Kelleyf632e562012-05-12 15:05:34 +0100815 Cope with router-solict packets wich don't have a valid
816 source address. Thanks to Vladislav Grishenko for the patch.
817
Simon Kelley919dd7c2012-05-12 15:23:09 +0100818 Fixed bug which caused missing periodic router
819 advertisements with some configurations. Thanks to
820 Vladislav Grishenko for the patch.
821
Simon Kelleyc64b7f62012-05-18 10:19:59 +0100822 Fixed bug which broke DHCPv6/RA with prefix lengths
823 which are not divisible by 8. Thanks to Andre Coetzee
824 for spotting this.
825
Simon Kelley18c63ef2012-05-21 14:34:15 +0100826 Fix non-response to router-solicitations when
827 router-advertisement configured, but DHCPv6 not
828 configured. Thanks to Marien Zwart for the patch.
829
Simon Kelley9f7f3b12012-05-28 21:39:57 +0100830 Add --dns-rr, to allow arbitrary DNS resource records.
831
Simon Kelley5ae34bf2012-06-04 21:14:03 +0100832 Fixed bug which broke RA scheduling when an interface had
833 two addresses in the same network. Thanks to Jim Bos for
834 his help nailing this.
835
Simon Kelleyeabc6dd2012-03-07 20:28:20 +0000836version 2.61
837 Re-write interface discovery code on *BSD to use
838 getifaddrs. This is more portable, more straightforward,
839 and allows us to find the prefix length for IPv6
840 addresses.
841
Simon Kelley01d1b8d2012-03-28 21:37:25 +0100842 Add ra-names, ra-stateless and slaac keywords for DHCPv6.
843 Dnsmasq can now synthesise AAAA records for dual-stack
844 hosts which get IPv6 addresses via SLAAC. It is also now
845 possible to use SLAAC and stateless DHCPv6, and to
846 tell clients to use SLAAC addresses as well as DHCP ones.
847 Thanks to Dave Taht for help with this.
Simon Kelley7023e382012-03-09 12:05:49 +0000848
Simon Kelley8b372702012-03-09 17:45:10 +0000849 Add --dhcp-duid to allow DUID-EN uids to be used.
850
Simon Kelley8643ec72012-03-12 20:04:14 +0000851 Explicity send DHCPv6 replies to the correct port, instead
852 of relying on clients to send requests with the correct
853 source address, since at least one client in the wild gets
Simon Kelley8358e0f2012-04-29 21:53:09 +0100854 this wrong. Thanks to Conrad Kostecki for help tracking
Simon Kelley8643ec72012-03-12 20:04:14 +0000855 this down.
Simon Kelleyeabc6dd2012-03-07 20:28:20 +0000856
Simon Kelley8643ec72012-03-12 20:04:14 +0000857 Send a preference value of 255 in DHCPv6 replies when
858 --dhcp-authoritative is in effect. This tells clients not
859 to wait around for other DHCP servers.
860
861 Better logging of DHCPv6 options.
862
Simon Kelleye759d422012-03-16 13:18:57 +0000863 Add --host-record. Thanks to Rob Zwissler for the
864 suggestion.
865
Simon Kelleya9530962012-03-20 22:07:35 +0000866 Invoke the DHCP script with action "tftp" when a TFTP file
867 transfer completes. The size of the file, address to which
868 it was sent and complete pathname are supplied. Note that
869 version 2.60 introduced some script incompatibilties
870 associated with DHCPv6, and this is a further change. To
871 be safe, scripts should ignore unknown actions, and if
872 not IPv6-aware, should exit if the environment
873 variable DNSMASQ_IAID is set. The use-case for this is
874 to track netboot/install. Suggestion from Shantanu
875 Gadgil.
876
877 Update contrib/port-forward/dnsmasq-portforward to reflect
878 the above.
879
880 Set the environment variable DNSMASQ_LOG_DHCP when running
881 the script id --log-dhcp is in effect, so that script can
Simon Kelley52d4abf2012-03-21 21:39:48 +0000882 taylor their logging verbosity. Suggestion from Malte
883 Forkel.
884
885 Arrange that addresses specified with --listen-address
886 work even if there is no interface carrying the
887 address. This is chiefly useful for IPv4 loopback
888 addresses, where any address in 127.0.0.0/8 is a valid
889 loopback address, but normally only 127.0.0.1 appears on
890 the lo interface. Thanks to Mathieu Trudel-Lapierre for
891 the idea and initial patch.
Simon Kelleya9530962012-03-20 22:07:35 +0000892
Simon Kelley7d2b5c92012-03-23 10:00:02 +0000893 Fix crash, introduced in 2.60, when a DHCPINFORM is
894 received from a network which has no valid dhcp-range.
895 Thanks to Stephane Glondu for the bug report.
896
Simon Kelleyc8257542012-03-28 21:15:41 +0100897 Add a new DHCP lease time keyword, "deprecated" for
898 --dhcp-range. This is only valid for IPv6, and sets the
899 preffered lease time for both DHCP and RA to zero. The
900 effect is that clients can continue to use the address
901 for existing connections, but new connections will use
902 other addresses, if they exist. This makes hitless
903 renumbering at least possible.
904
905 Fix bug in address6_available() which caused DHCPv6 lease
Simon Kelley8358e0f2012-04-29 21:53:09 +0100906 aquisition to fail if more than one dhcp-range in use.

Simon Kelley1023dcb2012-04-09 18:00:08 +0100915 Don't cache data from non-recursive nameservers, since it

Simon Kelleyc72daea2012-01-05 21:33:27 +0000947 Fix DHCP when using --listen-address with an IP address
948 which is not the primary address of an interface.
949
950 Add --dhcp-client-update option.
951
952 Add Lua integration. Dnsmasq can now execute a DHCP
953 lease-change script written in Lua. This needs to be
954 enabled at compile time by setting HAVE_LUASCRIPT in
955 src/config.h or running "make COPTS=-DHAVE_LUASCRIPT"
956 Thanks to Jan-Piet Mens for the idea and proof-of-concept
957 implementation.
958
959 Tidied src/config.h to distinguish between
960 platform-dependent compile-time options which are selected
961 automatically, and builder-selectable compile time
962 options. Document the latter better, and describe how to
963 set them from the make command line.
964
965 Tidied up IPPROTO_IP/SOL_IP (and IPv6 equivalent)
966 confusion. IPPROTO_IP works everywhere now.
967
968 Set TOS on DHCP sockets, this improves things on busy
969 wireless networks. Thanks to Dave Taht for the patch.

Simon Kelleya2761752012-01-18 16:07:21 +0000974 Improve start-up speed when reading large hosts files
975 containing many distinct addresses.
976
977 Fix problem if dnsmasq is started without the stdin,
978 stdout and stderr file descriptors open. This can manifest
979 itself as 100% CPU use. Thanks to Chris Moore for finding
980 this.
981
Simon Kelley9bbc8872012-02-09 21:33:09 +0000982 Fix shell-scripting bug in bld/pkg-wrapper. Thanks to
983 Mark Mitchell for the patch.
984
Simon Kelley751d6f42012-02-10 15:24:51 +0000985 Allow the TFP server or boot server in --pxe-service, to
986 be a domain name instead of an IP address. This allows for
987 round-robin to multiple servers, in the same way as
988 --dhcp-boot. A good suggestion from Cristiano Cumer.
989
Simon Kelleyfdacfb02012-02-28 15:20:25 +0000990 Support BUILDDIR variable in the Makefile. Allows builds
991 for multiple archs from the same source tree with eg.
992 make BUILDDIR=linux (relative to dnsmasq tree)
993 make BUILDDIR=/tmp/openbsd (absolute path)
Simon Kelleye5ffdb92012-02-13 14:19:25 +0000994 If BUILDDIR is not set, compilation happens in the src
Simon Kelleyb36ae192012-02-13 12:54:34 +0000995 directory, as before. Suggestion from Mark Mitchell.
996
Simon Kelleyfdacfb02012-02-28 15:20:25 +0000997 Support DHCPv6. Support is there for the sort of things
998 the existing v4 server does, including tags, options,
999 static addresses and relay support. Missing is prefix
1000 delegation, which is probably not required in the dnsmasq
1001 niche, and an easy way to accept prefix delegations from
1002 an upstream DHCPv6 server, which is. Future plans include
1003 support for DHCPv6 router option and MAC address option
1004 (to make selecting clients by MAC address work like IPv4).
1005 These will be added as the standards mature.
1006 This code has been tested, but this is the first release,
1007 so don't bet the farm on it just yet. Many thanks to all
1008 testers who have got it this far.
Simon Kelley1adadf52012-02-13 22:15:58 +00001009
Simon Kelleyac8540c2012-02-26 20:57:31 +00001010 Support IPv6 router advertisements. This is a
1011 simple-minded implementation, aimed at providing the
1012 vestigial RA needed to go alongside IPv6. Is picks up
1013 configuration from the DHCPv6 conf, and should just need
1014 enabling with --enable-ra.
1015
Simon Kelley552af8b2012-02-29 20:10:31 +00001016 Fix long-standing wrinkle with --localise-queries that
1017 could result in wrong answers when DNS packets arrive
1018 via an interface other than the expected one. Thanks to
1019 Lorenzo Milesi and John Hanks for spotting this one.

1025
Simon Kelleyc72daea2012-01-05 21:33:27 +00001026version 2.59
1027 Fix regression in 2.58 which caused failure to start up
1028 with some combinations of dnsmasq config and IPv6 kernel
1029 network config. Thanks to Brielle Bruns for the bug
1030 report.
1031
1032 Improve dnsmasq's behaviour when network interfaces are
1033 still doing duplicate address detection (DAD). Previously,
1034 dnsmasq would wait up to 20 seconds at start-up for the
1035 DAD state to terminate. This is broken for bridge
1036 interfaces on recent Linux kernels, which don't start DAD
1037 until the bridge comes up, and so can take arbitrary
1038 time. The new behaviour lets dnsmasq poll for an arbitrary
1039 time whilst providing service on other interfaces. Thanks
1040 to Stephen Hemminger for pointing out the problem.
Simon Kelley74c95c22011-10-19 09:33:39 +01001041
1042
Simon Kelley7de060b2011-08-26 17:24:52 +01001043version 2.58
1044 Provide a definition of the SA_SIZE macro where it's
1045 missing. Fixes build failure on openBSD.
1046
1047 Don't include a zero terminator at the end of messages
1048 sent to /dev/log when /dev/log is a datagram socket.
1049 Thanks to Didier Rabound for spotting the problem.
1050
1051 Add --dhcp-sequential-ip flag, to force allocation of IP
1052 addresses in ascending order. Note that the default
1053 pseudo-random mode is in general better but some
1054 server-deployment applications need this.
1055
1056 Fix problem where a server-id of 0.0.0.0 is sent to a
1057 client when a dhcp-relay is in use if a client renews a
1058 lease after dnsmasq restart and before any clients on the
1059 subnet get a new lease. Thanks to Mike Ruiz for assistance
1060 in chasing this one down.
1061
1062 Don't return NXDOMAIN to an AAAA query if we have CNAME
1063 which points to an A record only: NODATA is the correct
1064 reply in this case. Thanks to Tom Fernandes for spotting
1065 the problem.
1066
1067 Relax the need to supply a netmask in --dhcp-range for
1068 networks which use a DHCP relay. Whilst this is still
1069 desireable, in the absence of a netmask dnsmasq will use
1070 a default based on the class (A, B, or C) of the address.
1071 This should at least remove a cause of mysterious failure
1072 for people using RFC1918 addresses and relays.
1073
1074 Add support for Linux conntrack connection marking. If
1075 enabled with --conntrack, the connection mark for incoming
1076 DNS queries will be copied to the outgoing connections
1077 used to answer those queries. This allows clever firewall
1078 and accounting stuff. Only available if dnsmasq is
1079 compiled with HAVE_CONNTRACK and adds a dependency on
1080 libnetfilter-conntrack. Thanks to Ed Wildgoose for the
1081 initial idea, testing and sponsorship of this function.
1082
1083 Provide a sane error message when someone attempts to
1084 match a tag in --dhcp-host.
1085
1086 Tweak the behaviour of --domain-needed, to avoid problems
1087 with recursive nameservers downstream of dnsmasq. The new
1088 behaviour only stops A and AAAA queries, and returns
1089 NODATA rather than NXDOMAIN replies.
1090
1091 Efficiency fix for very large DHCP configurations, thanks
1092 to James Gartrell and Mike Ruiz for help with this.
1093
1094 Allow the TFTP-server address in --dhcp-boot to be a
1095 domain-name which is looked up in /etc/hosts. This can
1096 give multiple IP addresses which are used round-robin,
1097 thus doing TFTP server load-balancing. Thanks to Sushil
1098 Agrawal for the patch.
1099
1100 When two tagged dhcp-options for a particular option
1101 number are both valid, use the one which is valid without
1102 a tag from the dhcp-range. Allows overriding of the value
1103 of a DHCP option for a particular host as well as
1104 per-network values. So
1105 --dhcp-range=set:interface1,......
1106 --dhcp-host=set:myhost,.....
1107 --dhcp-option=tag:interface1,option:nis-domain,"domain1"
1108 --dhcp-option=tag:myhost,option:nis-domain,"domain2"
1109 will set the NIS-domain to domain1 for hosts in the range, but
1110 override that to domain2 for a particular host.
1111
1112 Fix bug which resulted in truncated files and timeouts for
1113 some TFTP transfers. The bug only occurs with netascii
1114 transfers and needs an unfortunate relationship between
1115 file size, blocksize and the number of newlines in the
1116 last block before it manifests itself. Many thanks to
1117 Alkis Georgopoulos for spotting the problem and providing
1118 a comprehensive test-case.
1119
1120 Fix regression in TFTP server on *BSD platforms introduced
1121 in version 2.56, due to confusion with sockaddr
Simon Kelleyde604c12012-10-19 09:50:01 +01001122 length. Many thanks to Loic Pefferkorn for finding this.
Simon Kelley7de060b2011-08-26 17:24:52 +01001123
1124 Support scope-ids in IPv6 addresses of nameservers from
1125 /etc/resolv.conf and in --server options. Eg
1126 nameserver fe80::202:a412:4512:7bbf%eth0 or
1127 server=fe80::202:a412:4512:7bbf%eth0. Thanks to
1128 Michael Stapelberg for the suggestion.
1129
1130 Update Polish translation, thanks to Jan Psota.

Simon Kelley572b41e2011-02-18 18:11:18 +00001135version 2.57
1136 Add patches to allow build under Android.
1137
1138 Provide our own header for the DNS protocol, rather than
1139 relying on arpa/nameser.h. This has proved more or less
1140 defective over the years and the final straw is that it's
1141 effectively empty on Android.
1142
1143 Fix regression in 2.56 which caused hex constants in
1144 configuration to be rejected if they contain the '*'
1145 wildcard.
1146
1147 Correct wrong casts of arguments to ctype.h functions,
1148 isdigit(), isxdigit() etc. Thanks to Matthias Andree for
1149 spotting this.
1150
1151 Allow build with IDN support independently from i18n.
1152 IDN support continues to be included automatically
1153 when i18n is included.
1154 'make COPTS=-DHAVE_IDN' is the magic incantation.
1155
1156 Modify check on extraneous command line junk (added in
1157 2.56) so that it doesn't complain about extra _empty_
1158 arguments. Otherwise this breaks libvirt.
1159
1160
Simon Kelley28866e92011-02-14 20:19:14 +00001161version 2.56
1162 Add a patch to allow dnsmasq to get interface names right in a
1163 Solaris zone. Thanks to Dj Padzensky for this.
1164
1165 Improve data-type parsing heuristics so that
1166 --dhcp-option=option:domain-search,.
1167 treats the value as a string and not an IP address.
1168 Thanks to Clemens Fischer for spotting that.
1169
1170 Add IPv6 support to the TFTP server. Many thanks to Jan
1171 'RedBully' Seiffert for the patches.
1172
1173 Log DNS queries at level LOG_INFO, rather then
1174 LOG_DEBUG. This makes things consistent with DHCP
1175 logging. Thanks to Adam Pribyl for spotting the problem.
1176
1177 Ensure that dnsmasq terminates cleanly when using
1178 --syslog-async even if it cannot make a connection to the
1179 syslogd.
1180
1181 Add --add-mac option. This is to support currently
1182 experimental DNS filtering facilities. Thanks to Benjamin
1183 Petrin for the orignal patch.
1184
1185 Fix bug which meant that tags were ignored in dhcp-range
1186 configuration specifying PXE-proxy service. Thanks to
1187 Cristiano Cumer for spotting this.
1188
1189 Raise an error if there is extra junk, not part of an
1190 option, on the command line.
1191
1192 Flag a couple of log messages in cache.c as coming from
1193 the DHCP subsystem. Thanks to Olaf Westrik for the patch.
1194
1195 Omit timestamps from logs when a) logging to stderr and
1196 b) --keep-in-forground is set. The logging facility on the
1197 other end of stderr can be assumned to supply them. Thanks
1198 to John Hallam for the patch.
1199
1200 Don't complain about strings longer than 255 characters in
1201 --txt-record, just split the long strings into 255
1202 character chunks instead.
1203
1204 Fix crash on double-free. This bug can only happen when
1205 dhcp-script is in use and then only in rare circumstances
1206 triggered by high DHCP transaction rate and a slow
1207 script. Thanks to Ferenc Wagner for finding the problem.
1208
1209 Only log that a file has been sent by TFTP after the
1210 transfer has completed succesfully.
1211
1212 A good suggestion from Ferenc Wagner: extend
1213 the --domain option to allow this sort of thing:
1214 --domain=thekelleys.org.uk,192.168.0.0/24,local
1215 which automatically creates
1216 --local=/thekelleys.org.uk/
1217 --local=/0.168.192.in-addr.arpa/
1218
1219 Tighten up syntax checking of hex contants in the config
1220 file. Thanks to Fred Damen for spotting this.
1221
1222 Add dnsmasq logo/icon, contributed by Justin Swift. Many
1223 thanks for that.
1224
1225 Never cache DNS replies which have the 'cd' bit set, or
1226 which result from queries forwarded with the 'cd' bit
1227 set. The 'cd' bit instructs a DNSSEC validating server
1228 upstream to ignore signature failures and return replies
1229 anyway. Without this change it's possible to pollute the
1230 dnsmasq cache with bad data by making a query with the
1231 'cd' bit set and subsequent queries would return this data
1232 without its being marked as suspect. Thanks to Anders
1233 Kaseorg for pointing out this problem.
1234
1235 Add --proxy-dnssec flag, for compliance with RFC
1236 4035. Dnsmasq will now clear the 'ad' bit in answers returned
1237 from upstream validating nameservers unless this option is
1238 set.
1239
1240 Allow a filename of "-" for --conf-file to read
1241 stdin. Suggestion from Timothy Redaelli.
1242
1243 Rotate the order of SRV records in replies, to provide
1244 round-robin load balancing when all the priorities are
1245 equal. Thanks to Peter McKinney for the suggestion.
1246
1247 Edit
1248 contrib/MacOSX-launchd/uk.org.thekelleys.dnsmasq.plist
1249 so that it doesn't log all queries to a file by
1250 default. Thanks again to Peter McKinney.
1251
1252 By default, setting an IPv4 address for a domain but not
1253 an IPv6 address causes dnsmasq to return
1254 an NODATA reply for IPv6 (or vice-versa). So
1255 --address=/google.com/1.2.3.4 stops IPv6 queries for
1256 *google.com from being forwarded. Make it possible to
1257 override this behaviour by defining the sematics if the
1258 same domain appears in both --server and --address.
1259 In that case, the --address has priority for the address
1260 family in which is appears, but the --server has priority
1261 of the address family which doesn't appear in --adddress
1262 So:
1263 --address=/google.com/1.2.3.4
1264 --server=/google.com/#
1265 will return 1.2.3.4 for IPv4 queries for *.google.com but
1266 forward IPv6 queries to the normal upstream nameserver.
1267 Similarly when setting an IPv6 address
1268 only this will allow forwarding of IPv4 queries. Thanks to
1269 William for pointing out the need for this.
1270
1271 Allow more than one --dhcp-optsfile and --dhcp-hostsfile
1272 and make them understand directories as arguments in the
1273 same way as --addn-hosts. Suggestion from John Hanks.
1274
1275 Ignore rebinding requests for leases we don't know
1276 about. Rebind is broadcast, so we might get to overhear a
1277 request meant for another DHCP server. NAKing this is
1278 wrong. Thanks to Brad D'Hondt for assistance with this.
1279
Simon Kelley572b41e2011-02-18 18:11:18 +00001280 Fix cosmetic bug which produced strange output when

Simon Kelley8ef5ada2010-06-03 19:42:45 +01001301version 2.53
1302 Fix failure to compile on Debian/kFreeBSD. Thanks to
1303 Axel Beckert and Petr Salinger.
1304
1305 Fix code to avoid scary strict-aliasing warnings
1306 generated by gcc 4.4.
1307
1308 Added FAQ entry warning about DHCP failures with Vista
1309 when firewalls block 255.255.255.255.
1310
1311 Fixed bug which caused bad things to happen if a
1312 resolv.conf file which exists is subsequently removed.
1313 Thanks to Nikolai Saoukh for the patch.
1314
1315 Rationalised the DHCP tag system. Every configuration item
1316 which can set a tag does so by adding "set:<tag>" and
1317 every configuration item which is conditional on a tag is
1318 made so by "tag:<tag>". The NOT operator changes to '!',
1319 which is a bit more intuitive too. Dhcp-host directives
1320 can set more than one tag now. The old '#' NOT,
1321 "net:" prefix and no-prefixes are still honoured, so
1322 no existing config file needs to be changed, but
1323 the documentation and new-style config files should be
1324 much less confusing.
1325
1326 Added --tag-if to allow boolean operations on tags.
1327 This allows complicated logic to be clearer and more
1328 general. A great suggestion from Richard Voigt.
1329
1330 Add broadcast/unicast information to DHCP logging.
1331
1332 Allow --dhcp-broadcast to be unconditional.
1333
1334 Fixed incorrect behaviour with NOT <tag> conditionals in
1335 dhcp-options. Thanks to Max Turkewitz for assistance
1336 finding this.
1337
1338 If we send vendor-class encapsulated options based on the
1339 vendor-class supplied by the client, and no explicit
1340 vendor-class option is given, echo back the vendor-class
1341 from the client.
1342
1343 Fix bug which stopped dnsmasq from matching both a
1344 circuitid and a remoteid. Thanks to Ignacio Bravo for
1345 finding this.
1346
1347 Add --dhcp-proxy, which makes it possible to configure
1348 dnsmasq to use a DHCP relay agent as a full proxy, with
1349 all DHCP messages passing through the proxy. This is
1350 useful if the relay adds extra information to the packets
1351 it forwards, but cannot be configured with the RFC 5107
1352 server-override option.
1353
1354 Added interface:<iface name> part to dhcp-range. The
1355 semantics of this are very odd at first sight, but it
1356 allows a single line of the form
1357 dhcp-range=interface:virt0,192.168.0.4,192.168.0.200
1358 to be added to dnsmasq configuration which then supplies
1359 DHCP and DNS services to that interface, without affecting
1360 what services are supplied to other interfaces and
1361 irrespective of the existance or lack of
1362 interface=<interface>
1363 lines elsewhere in the dnsmasq configuration. The idea is
1364 that such a line can be added automatically by libvirt
1365 or equivalent systems, without disturbing any manual
1366 configuration.
1367
1368 Similarly to the above, allow --enable-tftp=<interface>
1369
1370 Allow a TFTP root to be set separately for requests via
1371 different interfaces, --tftp-root=<path>,<interface>
1372
1373 Correctly handle and log clashes between CNAMES and
1374 DNS names being given to DHCP leases. This fixes a bug
1375 which caused nonsense IP addresses to be logged. Thanks to
1376 Sergei Zhirikov for finding and analysing the problem.
1377
1378 Tweak flush_log so as to avoid leaving the log
1379 file in non-blocking mode. O_NONBLOCK is a property of the
1380 file, not the process/descriptor.
1381
1382 Fix contrib/Solaris10/create_package
1383 (/usr/man -> /usr/share/man) Thanks to Vita Batrla.
1384
1385 Fix a problem where, if a client got a lease, then went
1386 to another subnet and got another lease, then moved back,
1387 it couldn't resume the old lease, but would instead get
1388 a new address. Thanks to Leonardo Rodrigues for spotting
1389 this and testing the fix.
1390
1391 Fix weird bug which sometimes omitted certain characters
1392 from the start of quoted strings in dhcp-options. Thanks
1393 to Dayton Turner for spotting the problem.
1394
1395 Add facility to redirect some domains to the standard
1396 upstream servers: this allows something like
1397 --server=/google.com/1.2.3.4 --server=/www.google.com/#
1398 which will send queries for *.google.com to 1.2.3.4,
1399 except *www.google.com which will be forwarded as usual.
1400 Thanks to AJ Weber for prompting this addition.
1401
1402 Improve the hash-algorithm used to generate IP addresses
1403 from MAC addresses during initial DHCP address
1404 allocation. This improves performance when large numbers
1405 of hosts with similar MAC addresses all try and get an IP
1406 address at the same time. Thanks to Paul Smith for his
1407 work on this.
1408
1409 Tweak DHCP code so that --bridge-interface can be used to
1410 select which IP alias of an interface should be used for
1411 DHCP purposes on Linux. If eth0 has an alias eth0:dhcp
1412 then adding --bridge-interface=eth0:dhcp,eth0 will use
1413 the address of eth0:dhcp to determine the correct subnet
1414 for DHCP address allocation. Thanks to Pawel Golaszewski
1415 for prompting this and Eric Cooper for further testing.
1416
1417 Add --dhcp-generate-names. Suggestion by Ferenc Wagner.
1418
1419 Tweak DNS server selection algorithm when there is more
1420 than one server available for a domain, eg.
1421 --server=/mydomain/1.1.1.1
1422 --server=/mydomain/2.2.2.2
1423 Thanks to Alberto Cuesta-Canada for spotting a weakness
1424 here.
1425
1426 Add --max-ttl. Thanks to Fredrik Ringertz for the patch.
1427
1428 Allow --log-facility=- to force all logging to
1429 stderr. Suggestion from Clemens Fischer.
1430
1431 Fix regression which caused configuration like
1432 --address=/.domain.com/1.2.3.4 to be rejected. The dot to the
1433 left of the domain has been implied and not required for a
1434 long time, but it should be accepted for backward
1435 compatibility. Thanks to Andrew Burcin for spotting this.
1436
1437 Add --rebind-domain-ok and --rebind-localhost-ok.
1438 Suggestion from Clemens Fischer.
1439
1440 Log replies to queries of type TXT, when --log-queries
1441 is set.
1442
1443 Fix compiler warnings when compiled with -DNO_DHCP. Thanks
1444 to Shantanu Gadgil for the patch.
1445

1452 Added contrib/static-arp, thanks to Darren Hoo.
1453
1454 Fix corruption of the domain when a name from /etc/hosts
1455 overrides one supplied by a DHCP client. Thanks to Fedor
1456 Kozhevnikov for spotting the problem.
1457
1458 Updated Spanish translation. Thanks to Chris Chatham.
1459
1460
Simon Kelley316e2732010-01-22 20:16:09 +00001461version 2.52
1462 Work around a Linux kernel bug which insists that the
1463 length of the option passed to setsockopt must be at least
1464 sizeof(int) bytes, even if we're calling SO_BINDTODEVICE
1465 and the device name is "lo". Note that this is fixed
1466 in kernel 2.6.31, but the workaround is harmless and
1467 allows earlier kernels to be used. Also fix dnsmasq
1468 bug which reported the wrong address when this failed.
1469 Thanks to Fedor for finding this.
1470
1471 The API for IPv6 PKTINFO changed around Linux kernel
1472 2.6.14. Workaround the case where dnsmasq is compiled
1473 against newer headers, but then run on an old kernel:
1474 necessary for some *WRT distros.
1475
1476 Re-read the set of network interfaces when re-loading
1477 /etc/resolv.conf if --bind-interfaces is not set. This
1478 handles the case that loopback interfaces do not exist
1479 when dnsmasq is first started.
1480
1481 Tweak the PXE code to support port 4011. This should
1482 reduce broadcasts and make things more reliable when other
1483 servers are around. It also improves inter-operability
1484 with certain clients.
1485
1486 Make a pxe-service configuration with no filename or boot
1487 service type legal: this does a local boot. eg.
1488 pxe-service=x86PC, "Local boot"
1489
1490 Be more conservative in detecting "A for A"
1491 queries. Dnsmasq checks if the name in a type=A query looks
1492 like a dotted-quad IP address and answers the query itself
1493 if so, rather than forwarding it. Previously dnsmasq
1494 relied in the library function inet_addr() to convert
1495 addresses, and that will accept some things which are
1496 confusing in this context, like 1.2.3 or even just
1497 1234. Now we only do A for A processing for four decimal
1498 numbers delimited by dots.
1499
1500 A couple of tweaks to fix compilation on Solaris. Thanks
1501 to Joel Macklow for help with this.
1502
1503 Another Solaris compilation tweak, needed for Solaris
1504 2009.06. Thanks to Lee Essen for that.
1505
1506 Added extract packaging stuff from Lee Essen to
1507 contrib/Solaris10.
1508
1509 Increased the default limit on number of leases to 1000
1510 (from 150). This is mainly a defence against DoS attacks,
1511 and for the average "one for two class C networks"
1512 installation, IP address exhaustion does that just as
1513 well. Making the limit greater than the number of IP
1514 addresses available in such an installation removes a
1515 surprise which otherwise can catch people out.
1516
1517 Removed extraneous trailing space in the value of the
1518 DNSMASQ_TIME_REMAINING DNSMASQ_LEASE_LENGTH and
1519 DNSMASQ_LEASE_EXPIRES environment variables. Thanks to
1520 Gildas Le Nadan for spotting this.
1521
1522 Provide the network-id tags for a DHCP transaction to
1523 the lease-change script in the environment variable
1524 DNSMASQ_TAGS. A good suggestion from Gildas Le Nadan.
1525
1526 Add support for RFC3925 "Vendor-Identifying Vendor
1527 Options". The syntax looks like this:
1528 --dhcp-option=vi-encap:<enterprise number>, .........
1529
1530 Add support to --dhcp-match to allow matching against
1531 RFC3925 "Vendor-Identifying Vendor Classes". The syntax
1532 looks like this:
1533 --dhcp-match=tag,vi-encap<enterprise number>, <value>
1534
1535 Add some application specific code to assist in
1536 implementing the Broadband forum TR069 CPE-WAN
1537 specification. The details are in contrib/CPE-WAN/README
1538
1539 Increase the default DNS packet size limit to 4096, as
1540 recommended by RFC5625 section 4.4.3. This can be
1541 reconfigured using --edns-packet-max if needed. Thanks to
1542 Francis Dupont for pointing this out.
1543
Simon Kelley8ef5ada2010-06-03 19:42:45 +01001544 Rewrite query-ids even for TSIG signed packets, since
Simon Kelley316e2732010-01-22 20:16:09 +00001545 this is allowed by RFC5625 section 4.5.
1546
1547 Use getopt_long by default on OS X. It has been supported
1548 since version 10.3.0. Thanks to Arek Dreyer for spotting
1549 this.
1550
1551 Added up-to-date startup configuration for MacOSX/launchd
1552 in contrib/MacOSX-launchd. Thanks to Arek Dreyer for
1553 providing this.

Simon Kelley8ef5ada2010-06-03 19:42:45 +01001564 Fixed confusion about domains, when looking up DHCP hosts
1565 in /etc/hosts. This could cause spurious "Ignoring
1566 domain..." messages. Thanks to Fedor Kozhevnikov for
1567 finding and analysing the problem.

Simon Kelley1f15b812009-10-13 17:49:32 +01001570version 2.51
1571 Add support for internationalised DNS. Non-ASCII characters
1572 in domain names found in /etc/hosts, /etc/ethers and
1573 /etc/dnsmasq.conf will be correctly handled by translation to
1574 punycode, as specified in RFC3490. This function is only
1575 available if dnsmasq is compiled with internationalisation
1576 support, and adds a dependency on GNU libidn. Without i18n
1577 support, dnsmasq continues to be compilable with just
1578 standard tools. Thanks to Yves Dorfsman for the
1579 suggestion.
1580
1581 Add two more environment variables for lease-change scripts:
1582 First, DNSMASQ_SUPPLIED_HOSTNAME; this is set to the hostname
1583 supplied by a client, even if the actual hostname used is
1584 over-ridden by dhcp-host or dhcp-ignore-names directives.
1585 Also DNSMASQ_RELAY_ADDRESS which gives the address of
1586 a DHCP relay, if used.
1587 Suggestions from Michael Rack.
1588
1589 Fix regression which broke echo of relay-agent
1590 options. Thanks to Michael Rack for spotting this.
1591
1592 Don't treat option 67 as being interchangeable with
1593 dhcp-boot parameters if it's specified as
1594 dhcp-option-force.
1595
1596 Make the code to call scripts on lease-change compile-time
1597 optional. It can be switched off by editing src/config.h
1598 or building with "make COPTS=-DNO_SCRIPT".
1599
1600 Make the TFTP server cope with filenames from Windows/DOS
1601 which use '\' as pathname separator. Thanks to Ralf for
1602 the patch.
1603
1604 Updated Polish translation. Thanks to Jan Psota.
1605
1606 Warn if an IP address is duplicated in /etc/ethers. Thanks
1607 to Felix Schwarz for pointing this out.
1608
1609 Teach --conf-dir to take an option list of file suffices
1610 which will be ignored when scanning the directory. Useful
1611 for backup files etc. Thanks to Helmut Hullen for the
1612 suggestion.
1613
1614 Add new DHCP option named tftpserver-address, which
1615 corresponds to the third argument of dhcp-boot. This
1616 allows the complete functionality of dhcp-boot to be
1617 replicated with dhcp-option. Useful when using
1618 dhcp-optsfile.
1619
1620 Test which upstream nameserver to use every 10 seconds
1621 or 50 queries and not just when a query times out and
1622 is retried. This should improve performance when there
1623 is a slow nameserver in the list. Thanks to Joe for the
1624 suggestion.
1625
1626 Don't do any PXE processing, even for clients with the
1627 correct vendorclass, unless at least one pxe-prompt or
1628 pxe-service option is given. This stops dnsmasq
1629 interfering with proxy PXE subsystems when it is just
1630 the DHCP server. Thanks to Spencer Clark for spotting this.
1631
1632 Limit the blocksize used for TFTP transfers to a value
1633 which avoids packet fragmentation, based on the MTU of the
1634 local interface. Many netboot ROMs can't cope with
1635 fragmented packets.
1636
1637 Honour dhcp-ignore configuration for PXE and proxy-PXE
1638 requests. Thanks to Niels Basjes for the bug report.
1639
1640 Updated French translation. Thanks to Gildas Le Nadan.

Simon Kelley1f15b812009-10-13 17:49:32 +01001644 Fix security problem which allowed any host permitted to
Simon Kelley77e94da2009-08-31 17:32:17 +01001645 do TFTP to possibly compromise dnsmasq by remote buffer
1646 overflow when TFTP enabled. Thanks to Core Security
1647 Technologies and Iván Arce, Pablo Hernán Jorge, Alejandro
1648 Pablo Rodriguez, Martín Coco, Alberto Soliño Testa and
1649 Pablo Annetta. This problem has Bugtraq id: 36121
1650 and CVE: 2009-2957
1651
1652 Fix a problem which allowed a malicious TFTP client to
1653 crash dnsmasq. Thanks to Steve Grubb at Red Hat for
1654 spotting this. This problem has Bugtraq id: 36120 and
1655 CVE: 2009-2958
1656
1657
Simon Kelley03a97b62009-06-10 20:55:49 +01001658version 2.49
1659 Fix regression in 2.48 which disables the lease-change
1660 script. Thanks to Jose Luis Duran for spotting this.
1661
1662 Log TFTP "file not found" errors. These were not logged,
1663 since a normal PXELinux boot generates many of them, but
1664 the lack of the messages seems to be more confusing than
1665 routinely seeing them when there is no real error.
1666
1667 Update Spanish translation. Thanks to Chris Chatham.

1671 Archived the extensive, backwards, changelog to
1672 CHANGELOG.archive. The current changelog now runs from
1673 version 2.43 and runs conventionally.
Simon Kelley9e4abcb2004-01-22 19:47:41 +00001674
Simon Kelley7622fc02009-06-04 20:32:05 +01001675 Fixed bug which broke binding of servers to physical
1676 interfaces when interface names were longer than four
1677 characters. Thanks to MURASE Katsunori for the patch.
Simon Kelley9e4abcb2004-01-22 19:47:41 +00001678
Simon Kelley7622fc02009-06-04 20:32:05 +01001679 Fixed netlink code to check that messages come from the
1680 correct source, and not another userspace process. Thanks
1681 to Steve Grubb for the patch.
Simon Kelley9e4abcb2004-01-22 19:47:41 +00001682
Simon Kelley7622fc02009-06-04 20:32:05 +01001683 Maintainability drive: removed bug and missing feature
1684 workarounds for some old platforms. Solaris 9, OpenBSD
1685 older than 4.1, Glibc older than 2.2, Linux 2.2.x and
1686 DBus older than 1.1.x are no longer supported.
Simon Kelley9e4abcb2004-01-22 19:47:41 +00001687
Simon Kelley7622fc02009-06-04 20:32:05 +01001688 Don't read included configuration files more than once:
1689 allows complex configuration structures without problems.
Simon Kelley9e4abcb2004-01-22 19:47:41 +00001690
Simon Kelley7622fc02009-06-04 20:32:05 +01001691 Mark log messages from the various subsystems in dnsmasq:
1692 messages from the DHCP subsystem now have the ident string
1693 "dnsmasq-dhcp" and messages from TFTP have ident
1694 "dnsmasq-tftp". Thanks to Olaf Westrik for the patch.
Simon Kelley9e4abcb2004-01-22 19:47:41 +00001695
Simon Kelley7622fc02009-06-04 20:32:05 +01001696 Fix possible infinite DHCP protocol loop when an IP
1697 address nailed to a hostname (not a MAC address) and a
1698 host sometimes provides the name, sometimes not.
Simon Kelley9e4abcb2004-01-22 19:47:41 +00001699
Simon Kelley7622fc02009-06-04 20:32:05 +01001700 Allow --addn-hosts to take a directory: all the files
1701 in the directory are read. Thanks to Phil Cornelius for
1702 the suggestion.
Simon Kelley9e4abcb2004-01-22 19:47:41 +00001703
Simon Kelley7622fc02009-06-04 20:32:05 +01001704 Support --bridge-interface on all platforms, not just BSD.
Simon Kelley1ab84e22004-01-29 16:48:35 +00001705
Simon Kelley7622fc02009-06-04 20:32:05 +01001706 Added support for advanced PXE functions. It's now
1707 possible to define a prompt and menu options which will
1708 be displayed when a client PXE boots. It's also possible to
1709 hand-off booting to other boot servers. Proxy-DHCP, where
1710 dnsmasq just supplies the PXE information and another DHCP
1711 server does address allocation, is also allowed. See the
1712 --pxe-prompt and --pxe-service keywords. Thanks to
1713 Alkis Georgopoulos for the suggestion and Guilherme Moro
1714 and Michael Brown for assistance.
Simon Kelley1ab84e22004-01-29 16:48:35 +00001715
Simon Kelley7622fc02009-06-04 20:32:05 +01001716 Improvements to DHCP logging. Thanks to Tom Metro for
1717 useful suggestions.
1718
1719 Add ability to build dnsmasq without DHCP support. To do
1720 this, edit src/config.h or build with
1721 "make COPTS=-DNO_DHCP". Thanks to Mahavir Jain for the patch.
1722
1723 Added --test command-line switch - syntax check
1724 configuration files only.
Simon Kelley33820b72004-04-03 21:10:00 +01001725
Simon Kelley7622fc02009-06-04 20:32:05 +01001726 Updated French translation. Thanks to Gildas Le Nadan.

Simon Kelley73a08a22009-02-05 20:28:08 +00001728
1729version 2.47
1730 Updated French translation. Thanks to Gildas Le Nadan.
1731
1732 Fixed interface enumeration code to work on NetBSD
1733 5.0. Thanks to Roy Marples for the patch.
1734
1735 Updated config.h to use the same location for the lease
1736 file on NetBSD as the other *BSD variants. Also allow
1737 LEASEFILE and CONFFILE symbols to be overriden in CFLAGS.
1738
1739 Handle duplicate address detection on IPv6 more
1740 intelligently. In IPv6, an interface can have an address
1741 which is not usable, because it is still undergoing DAD
1742 (such addresses are marked "tentative"). Attempting to
1743 bind to an address in this state returns an error,
1744 EADDRNOTAVAIL. Previously, on getting such an error,
1745 dnsmasq would silently abandon the address, and never
1746 listen on it. Now, it retries once per second for 20
1747 seconds before generating a fatal error. 20 seconds should
1748 be long enough for any DAD process to complete, but can be
1749 adjusted in src/config.h if necessary. Thanks to Martin
1750 Krafft for the bug report.
1751
1752 Add DBus introspection. Patch from Jeremy Laine.
1753
1754 Update Dbus configuration file. Patch from Colin Walters.
1755 Fix for this bug:
1756 http://bugs.freedesktop.org/show_bug.cgi?id=18961
1757
1758 Support arbitrarily encapsulated DHCP options, suggestion
1759 and initial patch from Samium Gromoff. This is useful for
1760 (eg) gPXE, which expect all its private options to be
1761 encapsulated inside a single option 175. So, eg,
1762
1763 dhcp-option = encap:175, 190, "iscsi-client0"
1764 dhcp-option = encap:175, 191, "iscsi-client0-secret"
1765
1766 will provide iSCSI parameters to gPXE.
1767
1768 Enhance --dhcp-match to allow testing of the contents of a
1769 client-sent option, as well as its presence. This
1770 application in mind for this is RFC 4578
1771 client-architecture specifiers, but it's generally useful.
1772 Joey Korkames suggested the enhancement.
1773
1774 Move from using the IP_XMIT_IF ioctl to IP_BOUND_IF on
1775 OpenSolaris. Thanks to Bastian Machek for the heads-up.
1776
1777 No longer complain about blank lines in
1778 /etc/ethers. Thanks to Jon Nelson for the patch.
1779
1780 Fix binding of servers to physical devices, eg
1781 --server=/domain/1.2.3.4@eth0 which was broken from 2.43
1782 onwards unless --query-port=0 set. Thanks to Peter Naulls
1783 for the bug report.
1784
1785 Reply to DHCPINFORM requests even when the supplied ciaddr
1786 doesn't fall in any dhcp-range. In this case it's not
1787 possible to supply a complete configuration, but
1788 individually-configured options (eg PAC) may be useful.
1789
1790 Allow the source address of an alias to be a range:
1791 --alias=192.168.0.0,10.0.0.0,255.255.255.0 maps the whole
1792 subnet 192.168.0.0->192.168.0.255 to 10.0.0.0->10.0.0.255,
1793 as before.
1794 --alias=192.168.0.10-192.168.0.40,10.0.0.0,255.255.255.0
1795 maps only the 192.168.0.10->192.168.0.40 region. Thanks to
1796 Ib Uhrskov for the suggestion.
1797
1798 Don't dynamically allocate DHCP addresses which may break
1799 Windows. Addresses which end in .255 or .0 are broken in
1800 Windows even when using supernetting.
1801 --dhcp-range=192.168.0.1,192.168.1.254,255,255,254.0 means
1802 192.168.0.255 is a valid IP address, but not for Windows.
1803 See Microsoft KB281579. We therefore no longer allocate
1804 these addresses to avoid hard-to-diagnose problems.
1805
1806 Update Polish translation. Thanks to Jan Psota.
1807
1808 Delete the PID-file when dnsmasq shuts down. Note that by
1809 this time, dnsmasq is normally not running as root, so
1810 this will fail if the PID-file is stored in a root-owned
1811 directory; such failure is silently ignored. To take
1812 advantage of this feature, the PID-file must be stored in a
1813 directory owned and write-able by the user running
1814 dnsmasq.
Simon Kelley7622fc02009-06-04 20:32:05 +01001815
1816
1817version 2.46
1818 Allow --bootp-dynamic to take a netid tag, so that it may
1819 be selectively enabled. Thanks to Olaf Westrik for the
1820 suggestion.
1821
1822 Remove ISC-leasefile reading code. This has been
1823 deprecated for a long time, and last time I removed it, it
1824 ended up going back by request of one user. This time,
1825 it's gone for good; otherwise it would need to be
1826 re-worked to support multiple domains (see below).
1827
1828 Support DHCP clients in multiple DNS domains. This is a
1829 long-standing request. Clients are assigned to a domain
1830 based in their IP address.
1831
1832 Add --dhcp-fqdn flag, which changes behaviour if DNS names
1833 assigned to DHCP clients. When this is set, there must be
1834 a domain associated with each client, and only
1835 fully-qualified domain names are added to the DNS. The
1836 advantage is that the only the FQDN needs to be unique,
1837 so that two or more DHCP clients can share a hostname, as
1838 long as they are in different domains.
1839
1840 Set environment variable DNSMASQ_DOMAIN when invoking
1841 lease-change script. This may be useful information to
1842 have now that it's variable.
1843
1844 Tighten up data-checking code for DNS packet
1845 handling. Thanks to Steve Dodd who found certain illegal
1846 packets which could crash dnsmasq. No memory overwrite was
1847 possible, so this is not a security issue beyond the DoS
1848 potential.
1849
1850 Update example config dhcp option 47, the previous
1851 suggestion generated an illegal, zero-length,
1852 option. Thanks to Matthias Andree for finding this.
1853
1854 Rewrite hosts-file reading code to remove the limit of
1855 1024 characters per line. John C Meuser found this.
1856
1857 Create a net-id tag with the name of the interface on
1858 which the DHCP request was received.
1859
1860 Fixed minor memory leak in DBus code, thanks to Jeremy
1861 Laine for the patch.
1862
1863 Emit DBus signals as the DHCP lease database
1864 changes. Thanks to Jeremy Laine for the patch.
1865
1866 Allow for more that one MAC address in a dhcp-host
1867 line. This configuration tells dnsmasq that it's OK to
1868 abandon a DHCP lease of the fixed address to one MAC
1869 address, if another MAC address in the dhcp-host statement
1870 asks for an address. This is useful to give a fixed
1871 address to a host which has two network interfaces
1872 (say, a laptop with wired and wireless interfaces.)
1873 It's very important to ensure that only one interface
1874 at a time is up, since dnsmasq abandons the first lease
1875 and re-uses the address before the leased time has
1876 elapsed. John Gray suggested this.
1877
1878 Tweak the response to a DHCP request packet with a wrong
1879 server-id when --dhcp-authoritative is set; dnsmasq now
1880 returns a DHCPNAK, rather than silently ignoring the
1881 packet. Thanks to Chris Marget for spotting this
1882 improvement.
1883
1884 Add --cname option. This provides a limited alias
1885 function, usable for DHCP names. Thanks to AJ Weber for
1886 suggestions on this.
1887
1888 Updated contrib/webmin with latest version from Neil
1889 Fisher.
1890
1891 Updated Polish translation. Thanks to Jan Psota.
1892
1893 Correct the text names for DHCP options 64 and 65 to be
1894 "nis+-domain" and "nis+-servers".
1895
1896 Updated Spanish translation. Thanks to Chris Chatham.
1897
1898 Force re-reading of /etc/resolv.conf when an "interface
1899 up" event occurs.
1900
1901
1902version 2.45
1903 Fix total DNS failure in release 2.44 unless --min-port
1904 specified. Thanks to Steven Barth and Grant Coady for
1905 bugreport. Also reject out-of-range port spec, which could
1906 break things too: suggestion from Gilles Espinasse.
1907
1908
1909version 2.44
1910 Fix crash when unknown client attempts to renew a DHCP
1911 lease, problem introduced in version 2.43. Thanks to
1912 Carlos Carvalho for help chasing this down.
1913
1914 Fix potential crash when a host which doesn't have a lease
1915 does DHCPINFORM. Again introduced in 2.43. This bug has
1916 never been reported in the wild.
1917
1918 Fix crash in netlink code introduced in 2.43. Thanks to
1919 Jean Wolter for finding this.
1920
1921 Change implementation of min_port to work even if min-port
1922 is large.
1923
1924 Patch to enable compilation of latest Mac OS X. Thanks to
1925 David Gilman.
1926
1927 Update Spanish translation. Thanks to Christopher Chatham.
1928
1929
1930version 2.43
1931 Updated Polish translation. Thanks to Jan Psota.
1932
1933 Flag errors when configuration options are repeated
1934 illegally.
1935
1936 Further tweaks for GNU/kFreeBSD
1937
1938 Add --no-wrap to msgmerge call - provides nicer .po file
1939 format.
1940
1941 Honour lease-time spec in dhcp-host lines even for
1942 BOOTP. The user is assumed to known what they are doing in
1943 this case. (Hosts without the time spec still get infinite
1944 leases for BOOTP, over-riding the default in the
1945 dhcp-range.) Thanks to Peter Katzmann for uncovering this.
1946
1947 Fix problem matching relay-agent ids. Thanks to Michael
1948 Rack for the bug report.
1949
1950 Add --naptr-record option. Suggestion from Johan
1951 Bergquist.
1952
1953 Implement RFC 5107 server-id-override DHCP relay agent
1954 option.
1955
1956 Apply patches from Stefan Kruger for compilation on
1957 Solaris 10 under Sun studio.
1958
1959 Yet more tweaking of Linux capability code, to suppress
1960 pointless wingeing from kernel 2.6.25 and above.
1961
1962 Improve error checking during startup. Previously, some
1963 errors which occurred during startup would be worked
1964 around, with dnsmasq still starting up. Some were logged,
1965 some silent. Now, they all cause a fatal error and dnsmasq
1966 terminates with a non-zero exit code. The errors are those
1967 associated with changing uid and gid, setting process
1968 capabilities and writing the pidfile. Thanks to Uwe
1969 Gansert and the Suse security team for pointing out
1970 this improvement, and Bill Reimers for good implementation
1971 suggestions.
1972
1973 Provide NO_LARGEFILE compile option to switch off largefile
1974 support when compiling against versions of uclibc which
1975 don't support it. Thanks to Stephane Billiart for the patch.
1976
1977 Implement random source ports for interactions with
1978 upstream nameservers. New spoofing attacks have been found
1979 against nameservers which do not do this, though it is not
1980 clear if dnsmasq is vulnerable, since to doesn't implement
1981 recursion. By default dnsmasq will now use a different
1982 source port (and socket) for each query it sends
1983 upstream. This behaviour can suppressed using the
1984 --query-port option, and the old default behaviour
1985 restored using --query-port=0. Explicit source-port
1986 specifications in --server configs are still honoured.
1987
1988 Replace the random number generator, for better
1989 security. On most BSD systems, dnsmasq uses the
1990 arc4random() RNG, which is secure, but on other platforms,
1991 it relied on the C-library RNG, which may be
1992 guessable and therefore allow spoofing. This release
1993 replaces the libc RNG with the SURF RNG, from Daniel
1994 J. Berstein's DJBDNS package.
1995
1996 Don't attempt to change user or group or set capabilities
1997 if dnsmasq is run as a non-root user. Without this, the
1998 change from soft to hard errors when these fail causes
1999 problems for non-root daemons listening on high
2000 ports. Thanks to Patrick McLean for spotting this.
2001
2002 Updated French translation. Thanks to Gildas Le Nadan.
