Simon Kelley1ee9be42013-12-09 16:50:19 +00001version 2.69
2 Implement dynamic interface discovery on *BSD. This allows
3 the contructor: syntax to be used in dhcp-range for DHCPv6
4 on the BSD platform. Thanks to Matthias Andree for
5 valuable research on how to implement this.

Simon Kelley8db957d2013-12-17 15:47:10 +00007 Fix infinite loop associated with some --bogus-nxdomain
Simon Kelley74e6b522013-12-17 21:33:53 +00008 configs. Thanks fogobogo for the bug report.

Simon Kelleyae762422014-01-10 18:15:16 +000010 Fix missing RA RDNS option with configuration like
11 --dhcp-option=option6:23,[::] Thanks to Tsachi Kimeldorfer
12 for spotting the problem.

Simon Kelley376d48c2013-11-13 13:04:30 +000015version 2.68
16 Use random addresses for DHCPv6 temporary address
17 allocations, instead of algorithmically determined stable
18 addresses.
19
20 Fix bug which meant that the DHCPv6 DUID was not available
21 in DHCP script runs during the lifetime of the dnsmasq
22 process which created the DUID de-novo. Once the DUID was
23 created and stored in the lease file and dnsmasq
24 restarted, this bug disappeared.
25
26 Fix bug introduced in 2.67 which could result in erroneous
27 NXDOMAIN returns to CNAME queries.
28
29 Fix build failures on MacOS X and openBSD.
30
31 Allow subnet specifications in --auth-zone to be interface
32 names as well as address literals. This makes it possible
33 to configure authoritative DNS when local address ranges
34 are dynamic and works much better than the previous
35 work-around which exempted contructed DHCP ranges from the
36 IP address filtering. As a consequence, that work-around
37 is removed. Under certain circumstances, this change wil
38 break existing configuration: if you're relying on the
39 contructed-range exception, you need to change --auth-zone
40 to specify the same interface as is used to construct your
41 DHCP ranges, probably with a trailing "/6" like this:
42 --auth-zone=example.com,eth0/6 to limit the addresses to
43 IPv6 addresses of eth0.
Simon Kelleydd9d9ce2013-11-15 11:24:00 +000044
45 Fix problems when advertising deleted IPv6 prefixes. If
46 the prefix is deleted (rather than replaced), it doesn't
47 get advertised with zero preferred time. Thanks to Tsachi
48 for the bug report.
Simon Kelley25439062013-11-25 21:14:51 +000049
50 Fix segfault with some locally configured CNAMEs. Thanks
51 to Andrew Childs for spotting the problem.
52
53 Fix memory leak on re-reading /etc/hosts and friends,
54 introduced in 2.67.
Simon Kelley2329bef2013-12-03 13:41:16 +000055
56 Check the arrival interface of incoming DNS and TFTP
57 requests via IPv6, even in --bind-interfaces mode. This
58 isn't possible for IPv4 and can generate scary warnings,
59 but as it's always possible for IPv6 (the API always
60 exists) then we should do it always.
Vladislav Grishenko4c82efc2013-12-03 16:05:30 +000061
62 Tweak the rules on prefix-lengths in --dhcp-range for
63 IPv6. The new rule is that the specified prefix length
64 must be larger than or equal to the prefix length of the
65 corresponding address on the local interface.
66

Giacomo Tazzari797a7af2013-04-22 13:16:37 +010068version 2.67
69 Fix crash if upstream server returns SERVFAIL when
70 --conntrack in use. Thanks to Giacomo Tazzari for finding
71 this and supplying the patch.
Simon Kelleyaa63a212013-04-22 15:01:52 +010072
73 Repair regression in 2.64. That release stopped sending
74 lease-time information in the reply to DHCPINFORM
75 requests, on the correct grounds that it was a standards
76 violation. However, this broke the dnsmasq-specific
77 dhcp_lease_time utility. Now, DHCPINFORM returns
78 lease-time only if it's specifically requested
79 (maintaining standards) and the dhcp_lease_time utility
80 has been taught to ask for it (restoring functionality).
Simon Kelley86e92f92013-04-23 11:31:39 +010081
82 Fix --dhcp-match, --dhcp-vendorclass and --dhcp-userclass
83 to work with BOOTP and well as DHCP. Thanks to Peter
84 Korsgaard for spotting the problem.
Simon Kelley2bb73af2013-04-24 17:38:19 +010085
86 Add --synth-domain. Thanks to Vishvananda Ishaya for
87 suggesting this.
Simon Kelleyd5052fb2013-04-25 12:44:20 +010088
89 Fix failure to compile ipset.c if old kernel headers are
90 in use. Thanks to Eugene Rudoy for pointing this out.
Simon Kelley3f2873d2013-05-14 11:28:47 +010091
92 Handle IPv4 interface-address labels in Linux. These are
93 often used to emulate the old IP-alias addresses. Before,
94 using --interface=eth0 would service all the addresses of
95 eth0, including ones configured as aliases, which appear
96 in ifconfig as eth0:0. Now, only addresses with the label
97 eth0 are active. This is not backwards compatible: if you
98 want to continue to bind the aliases too, you need to add
99 eg. --interface=eth0:0 to the config.
Giacomo Tazzari797a7af2013-04-22 13:16:37 +0100100
Simon Kelleycfcad422013-05-17 11:32:03 +0100101 Fix "failed to set SO_BINDTODEVICE on DHCP socket: Socket
102 operation on non-socket" error on startup with
103 configurations which have exactly one --interface option
104 and do RA but _not_ DHCPv6. Thanks to Trever Adams for the
105 bug report.
Giacomo Tazzari797a7af2013-04-22 13:16:37 +0100106
Simon Kelley115ac3e2013-05-20 11:28:32 +0100107 Generalise --interface-name to cope with IPv6 addresses
108 and multiple addresses per interface per address family.
109
Simon Kelley3e8ed782013-05-29 14:31:33 +0100110 Fix option parsing for --dhcp-host, which was generating a
111 spurious error when all seven possible items were
112 included. Thanks to Zhiqiang Wang for the bug report.
Simon Kelleybaa80ae2013-05-29 16:32:07 +0100113
114 Remove restriction on prefix-length in --auth-zone. Thanks
115 to Toke Hoiland-Jorgensen for suggesting this.
116
Marcelo Salhab Brogliato0da5e892013-05-31 11:49:06 +0100117 Log when the maximum number of concurrent DNS queries is
118 reached. Thanks to Marcelo Salhab Brogliato for the patch.
119
Simon Kelleye2ba0df2013-05-31 17:04:25 +0100120 If wildcards are used in --interface, don't assume that
121 there will only ever be one available interface for DHCP
122 just because there is one at start-up. More may appear, so
123 we can't use SO_BINDTODEVICE. Thanks to Natrio for the bug
124 report.
125
Simon Kelleyb4b93082013-06-19 10:31:23 +0100126 Increase timeout/number of retries in TFTP to accomodate
127 AudioCodes Voice Gateways doing streaming writes to flash.
128 Thanks to Damian Kaczkowski for spotting the problem.
129
Simon Kelley625ac282013-07-02 21:19:32 +0100130 Fix crash with empty DHCP string options when adding zero
Simon Kelley3953dcc2013-07-03 20:40:45 +0100131 terminator. Thanks to Patrick McLean for the bug report.
Simon Kelley625ac282013-07-02 21:19:32 +0100132
Kyle Mesteryd859ca22013-07-24 13:11:58 +0100133 Allow hostnames to start with a number, as allowed in
134 RFC-1123. Thanks to Kyle Mestery for the patch.
135
Roy Marples3f3adae2013-07-25 16:22:46 +0100136 Fixes to DHCP FQDN option handling: don't terminate FQDN
137 if domain not known and allow a FQDN option with blank
138 name to request that a FQDN option is returned in the
139 reply. Thanks to Roy Marples for the patch.
140
Simon Kelleyd9fb0be2013-07-25 21:47:17 +0100141 Make --clear-on-reload apply to setting upstream servers
142 via DBus too.
143
Simon Kelleyef1a94a2013-07-26 13:59:03 +0100144 When the address which triggered the construction of an
145 advertised IPv6 prefix disappears, continue to advertise
146 the prefix for up to 2 hours, with the preferred lifetime
147 set to zero. This satisfies RFC 6204 4.3 L-13 and makes
148 things work better if a prefix disappears without being
149 deprecated first. Thanks to Uwe Schindler for persuasively
150 arguing for this.
151
Simon Kelleyfc4c4fd2013-07-26 15:38:59 +0100152 Fix MAC address enumeration on *BSD. Thanks to Brad Smith
153 for the bug report.
Simon Kelleyb4b93082013-06-19 10:31:23 +0100154
Simon Kelley871d4562013-07-27 21:32:32 +0100155 Support RFC-4242 information-refresh-time options in the
156 reply to DHCPv6 information-request. The lease time of the
157 smallest valid dhcp-range is sent. Thanks to Uwe Schindler
158 for suggesting this.
159
Simon Kelleyedf0bde2013-07-29 17:21:48 +0100160 Make --listen-address higher priority than --except-interface
161 in all circumstances. Thanks to Thomas Hood for the bugreport.
162
Simon Kelley2937f8a2013-07-29 19:49:07 +0100163 Provide independent control over which interfaces get TFTP
164 service. If enable-tftp is given a list of interfaces, then TFTP
165 is provided on those. Without the list, the previous behaviour
166 (provide TFTP to the same interfaces we provide DHCP to)
167 is retained. Thanks to Lonnie Abelbeck for the suggestion.
168
Simon Kelley6acef732013-09-09 15:21:39 +0100169 Add --dhcp-relay config option. Many thanks to vtsl.net
170 for sponsoring this development.
Simon Kelleyff7eea22013-09-04 18:01:38 +0100171
Simon Kelley0932f9c2013-09-05 11:30:30 +0100172 Fix crash with empty tag: in --dhcp-range. Thanks to
173 Kaspar Schleiser for the bug report.
174
Simon Kelleyceae52d2013-09-12 15:05:47 +0100175 Add "baseline" and "bloatcheck" makefile targets, for
176 revealing size changes during development. Thanks to
177 Vladislav Grishenko for the patch.
178
Simon Kelleyc8f2dd82013-09-13 11:22:55 +0100179 Cope with DHCPv6 clients which send REQUESTs without
180 address options - treat them as SOLICIT with rapid commit.
181
Simon Kelley89500e32013-09-20 16:29:20 +0100182 Support identification of clients by MAC address in
183 DHCPv6. When using a relay, the relay must support RFC
184 6939 for this to work. It always works for directly
185 connected clients. Thanks to Vladislav Grishenko
186 for prompting this feature.
Simon Kelley861c8912013-09-25 15:30:30 +0100187
188 Remove the rule for constructed DHCP ranges that the local
189 address must be either the first or last address in the
190 range. This was originally to avoid SLAAC addresses, but
191 we now explicitly autoconfig and privacy addresses instead.
Simon Kelley89500e32013-09-20 16:29:20 +0100192
Simon Kelley889d8a12013-10-02 13:12:09 +0100193 Update Polish translation. Thanks to Jan Psota.
194
Tanguy Bouzelocef1d7422013-10-03 11:06:31 +0100195 Fix problem in DHCPv6 vendorclass/userclass matching
196 code. Thanks to Tanguy Bouzeloc for the patch.
197
Vic043c2712013-10-04 15:09:13 +0100198 Update Spanish transalation. Thanks to Vicente Soriano.
Simon Kelley871d4562013-07-27 21:32:32 +0100199
Simon Kelleyc4cd95d2013-10-10 20:58:11 +0100200 Add --ra-param option. Thanks to Vladislav Grishenko for
201 inspiration on this.
202
Simon Kelleyed4c0762013-10-08 20:46:34 +0100203 Add --add-subnet configuration, to tell upstream DNS
Simon Kelleyf65b0e52013-10-11 10:19:01 +0100204 servers where the original client is. Thanks to DNSthingy
205 for sponsoring this feature.
Simon Kelleyed4c0762013-10-08 20:46:34 +0100206
Kevin Darbyshire-Bryant8c0b73d2013-10-11 11:56:33 +0100207 Add --quiet-dhcp, --quiet-dhcp6 and --quiet-ra. Thanks to
208 Kevin Darbyshire-Bryant for the initial patch.
209
Simon Kelleyd56a6042013-10-11 14:39:03 +0100210 Allow A/AAAA records created by --interface-name to be the
211 target of --cname. Thanks to Hadmut Danisch for the
212 suggestion.
213
Simon Kelley24b5a5d2013-10-11 15:19:28 +0100214 Avoid treating a --dhcp-host which has an IPv6 address
215 as eligable for use with DHCPv4 on the grounds that it has
216 no address, and vice-versa. Thanks to Yury Konovalov for
217 spotting the problem.
218
Simon Kelley45cca582013-10-15 10:20:13 +0100219 Do a better job caching dangling CNAMEs. Thanks to Yves
220 Dorfsman for spotting the problem.
221
Vic043c2712013-10-04 15:09:13 +0100222
Simon Kelley333b2ce2013-01-07 21:46:03 +0000223version 2.66
224 Add the ability to act as an authoritative DNS
225 server. Dnsmasq can now answer queries from the wider 'net
226 with local data, as long as the correct NS records are set
227 up. Only local data is provided, to avoid creating an open
228 DNS relay. Zone transfer is supported, to allow secondary
229 servers to be configured.
230
231 Add "constructed DHCP ranges" for DHCPv6. This is intended
232 for IPv6 routers which get prefixes dynamically via prefix
233 delegation. With suitable configuration, stateful DHCPv6
234 and RA can happen automatically as prefixes are delegated
235 and then deprecated, without having to re-write the
236 dnsmasq configuration file or restart the daemon. Thanks to
237 Steven Barth for extensive testing and development work on
238 this idea.
Simon Kelley71c73ac2013-01-08 21:22:24 +0000239
240 Fix crash on startup on Solaris 11. Regression probably
Simon Kelley22ce5502013-01-22 13:53:04 +0000241 introduced in 2.61. Thanks to Geoff Johnstone for the
242 patch.
243
244 Add code to make behaviour for TCP DNS requests that same
245 as for UDP requests, when a request arrives for an allowed
246 address, but via a banned interface. This change is only
247 active on Linux, since the relevant API is missing (AFAIK)
248 on other platforms. Many thanks to Tomas Hozza for
249 spotting the problem, and doing invaluable discovery of
250 the obscure and undocumented API required for the solution.
Simon Kelleya21e27b2013-02-17 16:41:35 +0000251
252 Don't send the default DHCP option advertising dnsmasq as
253 the local DNS server if dnsmasq is configured to not act
254 as DNS server, or it's configured to a non-standard port.
Simon Kelleydd1721c2013-02-18 21:04:04 +0000255
256 Add DNSMASQ_CIRCUIT_ID, DNSMASQ_SUBCRIBER_ID,
257 DNSMASQ_REMOTE_ID variables to the environment of the
Simon Kelley3d77c042013-03-22 10:03:50 +0000258 lease-change script (and the corresponding Lua). These hold
Simon Kelleydd1721c2013-02-18 21:04:04 +0000259 information inserted into the DHCP request by a DHCP relay
260 agent. Thanks to Lakefield Communications for providing a
261 bounty for this addition.
262
Simon Kelley4038ae22013-02-19 16:47:07 +0000263 Fixed crash, introduced in 2.64, whilst handling DHCPv6
264 information-requests with some common configurations.
265 Thanks to Robert M. Albrecht for the bug report and
266 chasing the problem.
267
Jason A. Donenfeld13d86c72013-02-22 18:20:53 +0000268 Add --ipset option. Thanks to Jason A. Donenfeld for the
269 patch.
270
Simon Kelleyc7961072013-02-28 15:17:58 +0000271 Don't erroneously reject some option names in --dhcp-match
Simon Kelley3d77c042013-03-22 10:03:50 +0000272 options. Thanks to Benedikt Hochstrasser for the bug report.
Simon Kelley49333cb2013-03-15 20:30:51 +0000273
274 Allow a trailing '*' wildcard in all interface-name
275 configurations. Thanks to Christian Parpart for the patch.
Simon Kelleyc7961072013-02-28 15:17:58 +0000276
Simon Kelley56a11422013-04-02 17:02:58 +0100277 Handle the situation where libc headers define
278 SO_REUSEPORT, but the kernel in use doesn't, to cope with
279 the introduction of this option to Linux. Thanks to Rich
280 Felker for the bug report.
281
Simon Kelleycd1e04a2013-04-02 20:11:48 +0100282 Update Polish translation. Thanks to Jan Psota.
Simon Kelley0b0a73c2013-04-11 14:07:02 +0100283
284 Fix crash if the configured DHCP lease limit is
285 reached. Regression occurred in 2.61. Thanks to Tsachi for
286 the bug report.
Simon Kelleycd1e04a2013-04-02 20:11:48 +0100287
Simon Kelley834f36f2013-04-17 13:52:49 +0100288 Update the French translation. Thanks to Gildas le Nadan.

Simon Kelleyee86ce62012-12-07 11:54:46 +0000291version 2.65
292 Fix regression which broke forwarding of queries sent via
293 TCP which are not for A and AAAA and which were directed to
294 non-default servers. Thanks to Niax for the bug report.
295
Simon Kelleyb5a8dd12012-12-10 11:37:25 +0000296 Fix failure to build with DHCP support excluded. Thanks to
297 Gustavo Zacarias for the patch.
Simon Kelley1d6c6392012-12-14 11:19:36 +0000298
299 Fix nasty regression in 2.64 which completely broke cacheing.
Simon Kelleyb5a8dd12012-12-10 11:37:25 +0000300
301
Simon Kelley2e34ac12012-08-29 14:15:25 +0100302version 2.64
303 Handle DHCP FQDN options with all flag bits zero and
304 --dhcp-client-update set. Thanks to Bernd Krumbroeck for
305 spotting the problem.
306
Simon Kelley12d71ed2012-08-30 15:16:41 +0100307 Finesse the check for /etc/hosts names which conflict with
308 DHCP names. Previously a name/address pair in /etc/hosts
309 which didn't match the name/address of a DHCP lease would
310 generate a warning. Now that only happesn if there is not
311 also a match. This allows multiple addresses for a name in
312 /etc/hosts with one of them assigned via DHCP.
313
Simon Kelley4d0f5b42012-09-05 23:29:30 +0100314 Fix broken vendor-option processing for BOOTP. Thanks to
315 Hans-Joachim Baader for the bug report.
316
Simon Kelleydfb23b32012-09-18 21:44:47 +0100317 Don't report spurious netlink errors, regression in

325
Simon Kelley295a54e2012-12-01 21:02:15 +0000326 Add SetDomainServers method in DBus interface. Thanks to
327 Roy Marples for the patch.
328
Simon Kelley289a2532012-09-20 15:29:35 +0100329 Fix build with later Lua libraries. Thansk to Cristian
330 Rodriguez for the patch.

Simon Kelley1d860412012-09-20 20:48:04 +0100332 Add --max-cache-ttl option. Thanks to Dennis Kaarsemaker
333 for the patch.
334
Simon Kelleye4807d82012-09-27 21:52:26 +0100335 Fix breakage of --host-record parsing, resulting in
336 infinte loop at startup. Regression in 2.63. Thanks to
337 Haim Gelfenbeyn for spotting this.
338
Simon Kelley20223102012-10-15 10:41:17 +0100339 Set SO_REUSEADDRESS and SO_V6ONLY options on the DHCPv6
340 socket, this allows multiple instances of dnsmasq on a
341 single machine, in the same way as for DHCPv4. Thanks to
342 Gene Czarcinski and Vladislav Grishenko for work on this.
343
Simon Kelleybe6cfb42012-10-16 20:38:31 +0100344 Fix DHCPv6 to do access control correctly when it's
345 configured with --listen-address. Thanks to
346 Gene Czarcinski for sorting this out.
347
Simon Kelley819ff4d2012-10-21 18:25:12 +0100348 Add a "wildcard" dhcp-range which works for any IPv6
349 subnet, --dhcp-range=::,static Useful for Stateless
350 DHCPv6. Thanks to Vladislav Grishenko for the patch.
351
Simon Kelleyd1a59752012-11-05 16:50:30 +0000352 Don't include lease-time in DHCPACK replies to DHCPINFORM
353 queries, since RFC-2131 says we shouldn't. Thanks to
354 Wouter Ibens for pointing this out.
Simon Kelley8e4b8792012-11-14 14:12:56 +0000355
356 Makefile tweak to do dependency checking on header files.
357 Thanks to Johan Peeters for the patch.
Simon Kelleyd89fb4e2012-12-01 21:21:13 +0000358
359 Check interface for outgoing unsolicited router
360 advertisements, rather than relying on interface address
361 configuration. Thanks to Gene Czarinski for the patch.
Simon Kelley29d28dd2012-12-03 14:05:59 +0000362
363 Handle better attempts to transmit on interfaces which are
364 still doing DAD, and specifically do not just transmit
365 without setting source address and interface, since this
366 can cause very puzzling effects when a router
367 advertisement goes astray. Thanks again to Gene Czarinski.

369 Get RA timers right when there is more than one
370 dhcp-range on a subnet.

Simon Kelley8b3ae2f2012-06-13 13:43:49 +0100376 Check that tftp-root directories are accessible before
377 start-up. Thanks to Daniel Veillard for the initial patch.
378
379 Allow more than one --tfp-root flag. The per-interface
380 stuff is pointless without that.
381
Simon Kelley54dd3932012-06-20 11:23:38 +0100382 Add --bind-dynamic. A hybrid mode between the default and
383 --bind-interfaces which copes with dynamically created
384 interfaces.
Simon Kelley6b617c02012-06-29 21:15:42 +0100385
386 A couple of fixes to the build system for Android. Thanks
387 to Metin Kaya for the patches.
Simon Kelley54dd3932012-06-20 11:23:38 +0100388
Simon Kelley8bc4cec2012-07-03 21:04:11 +0100389 Remove the interface:<interface> argument in --dhcp-range, and
390 the interface argument to --enable-tftp. These were a
391 still-born attempt to allow automatic isolated
392 configuration by libvirt, but have never (to my knowledge)
393 been used, had very strange semantics, and have been
394 superceded by other mechanisms.
395
Simon Kelleyc4a7f902012-07-12 20:52:12 +0100396 Fixed bug logging filenames when duplicate dhcp-host
397 addresses are found. Thanks to John Hanks for the patch.
398
Simon Kelley611ebc52012-07-16 16:23:46 +0100399 Fix regression in 2.61 which broke caching of CNAME

Simon Kelley42243212012-07-20 15:19:18 +0100404 Teach DHCPv6 about the RFC 4242 information-refresh-time
405 option, and add parsing if the minutes, hours and days
406 format for options. Thanks to Francois-Xavier Le Bail for
407 the suggestion.
408
409 Allow "w" (for week) as multiplier in lease times, as well
410 as seconds, minutes, hours and days. Álvaro Gámez Machado
411 spotted the ommission.

429
Simon Kelley919dd7c2012-05-12 15:23:09 +0100430 Fixed bug which caused missing periodic router
431 advertisements with some configurations. Thanks to
432 Vladislav Grishenko for the patch.
433
Simon Kelleyc64b7f62012-05-18 10:19:59 +0100434 Fixed bug which broke DHCPv6/RA with prefix lengths
435 which are not divisible by 8. Thanks to Andre Coetzee
436 for spotting this.
437
Simon Kelley18c63ef2012-05-21 14:34:15 +0100438 Fix non-response to router-solicitations when
439 router-advertisement configured, but DHCPv6 not
440 configured. Thanks to Marien Zwart for the patch.
441
Simon Kelley9f7f3b12012-05-28 21:39:57 +0100442 Add --dns-rr, to allow arbitrary DNS resource records.
443
Simon Kelley5ae34bf2012-06-04 21:14:03 +0100444 Fixed bug which broke RA scheduling when an interface had
445 two addresses in the same network. Thanks to Jim Bos for
446 his help nailing this.
447
Simon Kelleyeabc6dd2012-03-07 20:28:20 +0000448version 2.61
449 Re-write interface discovery code on *BSD to use
450 getifaddrs. This is more portable, more straightforward,
451 and allows us to find the prefix length for IPv6
452 addresses.
453
Simon Kelley01d1b8d2012-03-28 21:37:25 +0100454 Add ra-names, ra-stateless and slaac keywords for DHCPv6.
455 Dnsmasq can now synthesise AAAA records for dual-stack
456 hosts which get IPv6 addresses via SLAAC. It is also now
457 possible to use SLAAC and stateless DHCPv6, and to
458 tell clients to use SLAAC addresses as well as DHCP ones.
459 Thanks to Dave Taht for help with this.
Simon Kelley7023e382012-03-09 12:05:49 +0000460
Simon Kelley8b372702012-03-09 17:45:10 +0000461 Add --dhcp-duid to allow DUID-EN uids to be used.

Simon Kelley8643ec72012-03-12 20:04:14 +0000463 Explicity send DHCPv6 replies to the correct port, instead
464 of relying on clients to send requests with the correct
465 source address, since at least one client in the wild gets
Simon Kelley8358e0f2012-04-29 21:53:09 +0100466 this wrong. Thanks to Conrad Kostecki for help tracking
Simon Kelley8643ec72012-03-12 20:04:14 +0000467 this down.
Simon Kelleyeabc6dd2012-03-07 20:28:20 +0000468

470 --dhcp-authoritative is in effect. This tells clients not
471 to wait around for other DHCP servers.
472
473 Better logging of DHCPv6 options.
474
Simon Kelleye759d422012-03-16 13:18:57 +0000475 Add --host-record. Thanks to Rob Zwissler for the
476 suggestion.
477
Simon Kelleya9530962012-03-20 22:07:35 +0000478 Invoke the DHCP script with action "tftp" when a TFTP file
479 transfer completes. The size of the file, address to which
480 it was sent and complete pathname are supplied. Note that
481 version 2.60 introduced some script incompatibilties
482 associated with DHCPv6, and this is a further change. To
483 be safe, scripts should ignore unknown actions, and if
484 not IPv6-aware, should exit if the environment
485 variable DNSMASQ_IAID is set. The use-case for this is
486 to track netboot/install. Suggestion from Shantanu
487 Gadgil.
488
489 Update contrib/port-forward/dnsmasq-portforward to reflect
490 the above.
491
492 Set the environment variable DNSMASQ_LOG_DHCP when running
493 the script id --log-dhcp is in effect, so that script can
Simon Kelley52d4abf2012-03-21 21:39:48 +0000494 taylor their logging verbosity. Suggestion from Malte
495 Forkel.
496
497 Arrange that addresses specified with --listen-address
498 work even if there is no interface carrying the
499 address. This is chiefly useful for IPv4 loopback
500 addresses, where any address in 127.0.0.0/8 is a valid
501 loopback address, but normally only 127.0.0.1 appears on
502 the lo interface. Thanks to Mathieu Trudel-Lapierre for
503 the idea and initial patch.

Simon Kelley7d2b5c92012-03-23 10:00:02 +0000505 Fix crash, introduced in 2.60, when a DHCPINFORM is
506 received from a network which has no valid dhcp-range.
507 Thanks to Stephane Glondu for the bug report.
508
Simon Kelleyc8257542012-03-28 21:15:41 +0100509 Add a new DHCP lease time keyword, "deprecated" for
510 --dhcp-range. This is only valid for IPv6, and sets the
511 preffered lease time for both DHCP and RA to zero. The
512 effect is that clients can continue to use the address
513 for existing connections, but new connections will use
514 other addresses, if they exist. This makes hitless
515 renumbering at least possible.
516
517 Fix bug in address6_available() which caused DHCPv6 lease
Simon Kelley8358e0f2012-04-29 21:53:09 +0100518 aquisition to fail if more than one dhcp-range in use.

Simon Kelleyc72daea2012-01-05 21:33:27 +0000559 Fix DHCP when using --listen-address with an IP address
560 which is not the primary address of an interface.
561
562 Add --dhcp-client-update option.
563
564 Add Lua integration. Dnsmasq can now execute a DHCP
565 lease-change script written in Lua. This needs to be
566 enabled at compile time by setting HAVE_LUASCRIPT in
567 src/config.h or running "make COPTS=-DHAVE_LUASCRIPT"
568 Thanks to Jan-Piet Mens for the idea and proof-of-concept
569 implementation.
570
571 Tidied src/config.h to distinguish between
572 platform-dependent compile-time options which are selected
573 automatically, and builder-selectable compile time
574 options. Document the latter better, and describe how to
575 set them from the make command line.
576
577 Tidied up IPPROTO_IP/SOL_IP (and IPv6 equivalent)
578 confusion. IPPROTO_IP works everywhere now.
579
580 Set TOS on DHCP sockets, this improves things on busy
581 wireless networks. Thanks to Dave Taht for the patch.

587 containing many distinct addresses.
588
589 Fix problem if dnsmasq is started without the stdin,
590 stdout and stderr file descriptors open. This can manifest
591 itself as 100% CPU use. Thanks to Chris Moore for finding
592 this.
593
Simon Kelley9bbc8872012-02-09 21:33:09 +0000594 Fix shell-scripting bug in bld/pkg-wrapper. Thanks to
595 Mark Mitchell for the patch.
596
Simon Kelley751d6f42012-02-10 15:24:51 +0000597 Allow the TFP server or boot server in --pxe-service, to
598 be a domain name instead of an IP address. This allows for
599 round-robin to multiple servers, in the same way as
600 --dhcp-boot. A good suggestion from Cristiano Cumer.
601
Simon Kelleyfdacfb02012-02-28 15:20:25 +0000602 Support BUILDDIR variable in the Makefile. Allows builds
603 for multiple archs from the same source tree with eg.
604 make BUILDDIR=linux (relative to dnsmasq tree)
605 make BUILDDIR=/tmp/openbsd (absolute path)
Simon Kelleye5ffdb92012-02-13 14:19:25 +0000606 If BUILDDIR is not set, compilation happens in the src
Simon Kelleyb36ae192012-02-13 12:54:34 +0000607 directory, as before. Suggestion from Mark Mitchell.
608
Simon Kelleyfdacfb02012-02-28 15:20:25 +0000609 Support DHCPv6. Support is there for the sort of things
610 the existing v4 server does, including tags, options,
611 static addresses and relay support. Missing is prefix
612 delegation, which is probably not required in the dnsmasq
613 niche, and an easy way to accept prefix delegations from
614 an upstream DHCPv6 server, which is. Future plans include
615 support for DHCPv6 router option and MAC address option
616 (to make selecting clients by MAC address work like IPv4).
617 These will be added as the standards mature.
618 This code has been tested, but this is the first release,
619 so don't bet the farm on it just yet. Many thanks to all
620 testers who have got it this far.
Simon Kelley1adadf52012-02-13 22:15:58 +0000621
Simon Kelleyac8540c2012-02-26 20:57:31 +0000622 Support IPv6 router advertisements. This is a
623 simple-minded implementation, aimed at providing the
624 vestigial RA needed to go alongside IPv6. Is picks up
625 configuration from the DHCPv6 conf, and should just need
626 enabling with --enable-ra.
627
Simon Kelley552af8b2012-02-29 20:10:31 +0000628 Fix long-standing wrinkle with --localise-queries that
629 could result in wrong answers when DNS packets arrive
630 via an interface other than the expected one. Thanks to
631 Lorenzo Milesi and John Hanks for spotting this one.
Simon Kelley71ee7ee2012-03-03 18:06:49 +0000632

636
637
Simon Kelleyc72daea2012-01-05 21:33:27 +0000638version 2.59
639 Fix regression in 2.58 which caused failure to start up
640 with some combinations of dnsmasq config and IPv6 kernel
641 network config. Thanks to Brielle Bruns for the bug
642 report.
643
644 Improve dnsmasq's behaviour when network interfaces are
645 still doing duplicate address detection (DAD). Previously,
646 dnsmasq would wait up to 20 seconds at start-up for the
647 DAD state to terminate. This is broken for bridge
648 interfaces on recent Linux kernels, which don't start DAD
649 until the bridge comes up, and so can take arbitrary
650 time. The new behaviour lets dnsmasq poll for an arbitrary
651 time whilst providing service on other interfaces. Thanks
652 to Stephen Hemminger for pointing out the problem.
Simon Kelley74c95c22011-10-19 09:33:39 +0100653
654
Simon Kelley7de060b2011-08-26 17:24:52 +0100655version 2.58
656 Provide a definition of the SA_SIZE macro where it's
657 missing. Fixes build failure on openBSD.
658
659 Don't include a zero terminator at the end of messages
660 sent to /dev/log when /dev/log is a datagram socket.
661 Thanks to Didier Rabound for spotting the problem.
662
663 Add --dhcp-sequential-ip flag, to force allocation of IP
664 addresses in ascending order. Note that the default
665 pseudo-random mode is in general better but some
666 server-deployment applications need this.
667
668 Fix problem where a server-id of 0.0.0.0 is sent to a
669 client when a dhcp-relay is in use if a client renews a
670 lease after dnsmasq restart and before any clients on the
671 subnet get a new lease. Thanks to Mike Ruiz for assistance
672 in chasing this one down.
673
674 Don't return NXDOMAIN to an AAAA query if we have CNAME
675 which points to an A record only: NODATA is the correct
676 reply in this case. Thanks to Tom Fernandes for spotting
677 the problem.
678
679 Relax the need to supply a netmask in --dhcp-range for
680 networks which use a DHCP relay. Whilst this is still
681 desireable, in the absence of a netmask dnsmasq will use
682 a default based on the class (A, B, or C) of the address.
683 This should at least remove a cause of mysterious failure
684 for people using RFC1918 addresses and relays.
685
686 Add support for Linux conntrack connection marking. If
687 enabled with --conntrack, the connection mark for incoming
688 DNS queries will be copied to the outgoing connections
689 used to answer those queries. This allows clever firewall
690 and accounting stuff. Only available if dnsmasq is
691 compiled with HAVE_CONNTRACK and adds a dependency on
692 libnetfilter-conntrack. Thanks to Ed Wildgoose for the
693 initial idea, testing and sponsorship of this function.
694
695 Provide a sane error message when someone attempts to
696 match a tag in --dhcp-host.
697
698 Tweak the behaviour of --domain-needed, to avoid problems
699 with recursive nameservers downstream of dnsmasq. The new
700 behaviour only stops A and AAAA queries, and returns
701 NODATA rather than NXDOMAIN replies.
702
703 Efficiency fix for very large DHCP configurations, thanks
704 to James Gartrell and Mike Ruiz for help with this.
705
706 Allow the TFTP-server address in --dhcp-boot to be a
707 domain-name which is looked up in /etc/hosts. This can
708 give multiple IP addresses which are used round-robin,
709 thus doing TFTP server load-balancing. Thanks to Sushil
710 Agrawal for the patch.
711
712 When two tagged dhcp-options for a particular option
713 number are both valid, use the one which is valid without
714 a tag from the dhcp-range. Allows overriding of the value
715 of a DHCP option for a particular host as well as
716 per-network values. So
717 --dhcp-range=set:interface1,......
718 --dhcp-host=set:myhost,.....
719 --dhcp-option=tag:interface1,option:nis-domain,"domain1"
720 --dhcp-option=tag:myhost,option:nis-domain,"domain2"
721 will set the NIS-domain to domain1 for hosts in the range, but
722 override that to domain2 for a particular host.
723
724 Fix bug which resulted in truncated files and timeouts for
725 some TFTP transfers. The bug only occurs with netascii
726 transfers and needs an unfortunate relationship between
727 file size, blocksize and the number of newlines in the
728 last block before it manifests itself. Many thanks to
729 Alkis Georgopoulos for spotting the problem and providing
730 a comprehensive test-case.
731
732 Fix regression in TFTP server on *BSD platforms introduced
733 in version 2.56, due to confusion with sockaddr

Simon Kelley7de060b2011-08-26 17:24:52 +0100735
736 Support scope-ids in IPv6 addresses of nameservers from
737 /etc/resolv.conf and in --server options. Eg
738 nameserver fe80::202:a412:4512:7bbf%eth0 or
739 server=fe80::202:a412:4512:7bbf%eth0. Thanks to
740 Michael Stapelberg for the suggestion.
741
742 Update Polish translation, thanks to Jan Psota.
743
744 Update French translation. Thanks to Gildas Le Nadan.

746
Simon Kelley572b41e2011-02-18 18:11:18 +0000747version 2.57
748 Add patches to allow build under Android.
749
750 Provide our own header for the DNS protocol, rather than
751 relying on arpa/nameser.h. This has proved more or less
752 defective over the years and the final straw is that it's
753 effectively empty on Android.
754
755 Fix regression in 2.56 which caused hex constants in
756 configuration to be rejected if they contain the '*'
757 wildcard.
758
759 Correct wrong casts of arguments to ctype.h functions,
760 isdigit(), isxdigit() etc. Thanks to Matthias Andree for
761 spotting this.
762
763 Allow build with IDN support independently from i18n.
764 IDN support continues to be included automatically
765 when i18n is included.
766 'make COPTS=-DHAVE_IDN' is the magic incantation.
767
768 Modify check on extraneous command line junk (added in
769 2.56) so that it doesn't complain about extra _empty_
770 arguments. Otherwise this breaks libvirt.
771
772
Simon Kelley28866e92011-02-14 20:19:14 +0000773version 2.56
774 Add a patch to allow dnsmasq to get interface names right in a
775 Solaris zone. Thanks to Dj Padzensky for this.
776
777 Improve data-type parsing heuristics so that
778 --dhcp-option=option:domain-search,.
779 treats the value as a string and not an IP address.
780 Thanks to Clemens Fischer for spotting that.
781
782 Add IPv6 support to the TFTP server. Many thanks to Jan
783 'RedBully' Seiffert for the patches.
784
785 Log DNS queries at level LOG_INFO, rather then
786 LOG_DEBUG. This makes things consistent with DHCP
787 logging. Thanks to Adam Pribyl for spotting the problem.
788
789 Ensure that dnsmasq terminates cleanly when using
790 --syslog-async even if it cannot make a connection to the
791 syslogd.
792
793 Add --add-mac option. This is to support currently
794 experimental DNS filtering facilities. Thanks to Benjamin
795 Petrin for the orignal patch.
796
797 Fix bug which meant that tags were ignored in dhcp-range
798 configuration specifying PXE-proxy service. Thanks to
799 Cristiano Cumer for spotting this.
800
801 Raise an error if there is extra junk, not part of an
802 option, on the command line.
803
804 Flag a couple of log messages in cache.c as coming from
805 the DHCP subsystem. Thanks to Olaf Westrik for the patch.
806
807 Omit timestamps from logs when a) logging to stderr and
808 b) --keep-in-forground is set. The logging facility on the
809 other end of stderr can be assumned to supply them. Thanks
810 to John Hallam for the patch.
811
812 Don't complain about strings longer than 255 characters in
813 --txt-record, just split the long strings into 255
814 character chunks instead.
815
816 Fix crash on double-free. This bug can only happen when
817 dhcp-script is in use and then only in rare circumstances
818 triggered by high DHCP transaction rate and a slow
819 script. Thanks to Ferenc Wagner for finding the problem.
820
821 Only log that a file has been sent by TFTP after the
822 transfer has completed succesfully.
823
824 A good suggestion from Ferenc Wagner: extend
825 the --domain option to allow this sort of thing:
826 --domain=thekelleys.org.uk,192.168.0.0/24,local
827 which automatically creates
828 --local=/thekelleys.org.uk/
829 --local=/0.168.192.in-addr.arpa/
830
831 Tighten up syntax checking of hex contants in the config
832 file. Thanks to Fred Damen for spotting this.
833
834 Add dnsmasq logo/icon, contributed by Justin Swift. Many
835 thanks for that.
836
837 Never cache DNS replies which have the 'cd' bit set, or
838 which result from queries forwarded with the 'cd' bit
839 set. The 'cd' bit instructs a DNSSEC validating server
840 upstream to ignore signature failures and return replies
841 anyway. Without this change it's possible to pollute the
842 dnsmasq cache with bad data by making a query with the
843 'cd' bit set and subsequent queries would return this data
844 without its being marked as suspect. Thanks to Anders
845 Kaseorg for pointing out this problem.
846
847 Add --proxy-dnssec flag, for compliance with RFC
848 4035. Dnsmasq will now clear the 'ad' bit in answers returned
849 from upstream validating nameservers unless this option is
850 set.
851
852 Allow a filename of "-" for --conf-file to read
853 stdin. Suggestion from Timothy Redaelli.
854
855 Rotate the order of SRV records in replies, to provide
856 round-robin load balancing when all the priorities are
857 equal. Thanks to Peter McKinney for the suggestion.
858
859 Edit
860 contrib/MacOSX-launchd/uk.org.thekelleys.dnsmasq.plist
861 so that it doesn't log all queries to a file by
862 default. Thanks again to Peter McKinney.
863
864 By default, setting an IPv4 address for a domain but not
865 an IPv6 address causes dnsmasq to return
866 an NODATA reply for IPv6 (or vice-versa). So
867 --address=/google.com/1.2.3.4 stops IPv6 queries for
868 *google.com from being forwarded. Make it possible to
869 override this behaviour by defining the sematics if the
870 same domain appears in both --server and --address.
871 In that case, the --address has priority for the address
872 family in which is appears, but the --server has priority
873 of the address family which doesn't appear in --adddress
874 So:
875 --address=/google.com/1.2.3.4
876 --server=/google.com/#
877 will return 1.2.3.4 for IPv4 queries for *.google.com but
878 forward IPv6 queries to the normal upstream nameserver.
879 Similarly when setting an IPv6 address
880 only this will allow forwarding of IPv4 queries. Thanks to
881 William for pointing out the need for this.
882
883 Allow more than one --dhcp-optsfile and --dhcp-hostsfile
884 and make them understand directories as arguments in the
885 same way as --addn-hosts. Suggestion from John Hanks.
886
887 Ignore rebinding requests for leases we don't know
888 about. Rebind is broadcast, so we might get to overhear a
889 request meant for another DHCP server. NAKing this is
890 wrong. Thanks to Brad D'Hondt for assistance with this.
891
Simon Kelley572b41e2011-02-18 18:11:18 +0000892 Fix cosmetic bug which produced strange output when
893 dumping cache statistics with some configurations. Thanks
894 to Fedor Kozhevnikov for spotting this.

Simon Kelleyc52e1892010-06-07 22:01:39 +0100897version 2.55
Simon Kelley28866e92011-02-14 20:19:14 +0000898 Fix crash when /etc/ethers is in use. Thanks to
899 Gianluigi Tiesi for finding this.
Simon Kelleyc52e1892010-06-07 22:01:39 +0100900
Simon Kelley28866e92011-02-14 20:19:14 +0000901 Fix crash in netlink_multicast(). Thanks to Arno Wald for
902 finding this one.
Simon Kelleyc52e1892010-06-07 22:01:39 +0100903
Simon Kelley28866e92011-02-14 20:19:14 +0000904 Allow the empty domain "." in dhcp domain-search (119)
905 options.

908version 2.54
Simon Kelley28866e92011-02-14 20:19:14 +0000909 There is no version 2.54 to avoid confusion with 2.53,
910 which incorrectly identifies itself as 2.54.
Simon Kelleyc52e1892010-06-07 22:01:39 +0100911
912
Simon Kelley8ef5ada2010-06-03 19:42:45 +0100913version 2.53
914 Fix failure to compile on Debian/kFreeBSD. Thanks to
915 Axel Beckert and Petr Salinger.
916
917 Fix code to avoid scary strict-aliasing warnings
918 generated by gcc 4.4.
919
920 Added FAQ entry warning about DHCP failures with Vista
921 when firewalls block 255.255.255.255.
922
923 Fixed bug which caused bad things to happen if a
924 resolv.conf file which exists is subsequently removed.
925 Thanks to Nikolai Saoukh for the patch.
926
927 Rationalised the DHCP tag system. Every configuration item
928 which can set a tag does so by adding "set:<tag>" and
929 every configuration item which is conditional on a tag is
930 made so by "tag:<tag>". The NOT operator changes to '!',
931 which is a bit more intuitive too. Dhcp-host directives
932 can set more than one tag now. The old '#' NOT,
933 "net:" prefix and no-prefixes are still honoured, so
934 no existing config file needs to be changed, but
935 the documentation and new-style config files should be
936 much less confusing.
937
938 Added --tag-if to allow boolean operations on tags.
939 This allows complicated logic to be clearer and more
940 general. A great suggestion from Richard Voigt.
941
942 Add broadcast/unicast information to DHCP logging.
943
944 Allow --dhcp-broadcast to be unconditional.
945
946 Fixed incorrect behaviour with NOT <tag> conditionals in
947 dhcp-options. Thanks to Max Turkewitz for assistance
948 finding this.
949
950 If we send vendor-class encapsulated options based on the
951 vendor-class supplied by the client, and no explicit
952 vendor-class option is given, echo back the vendor-class
953 from the client.
954
955 Fix bug which stopped dnsmasq from matching both a
956 circuitid and a remoteid. Thanks to Ignacio Bravo for
957 finding this.
958
959 Add --dhcp-proxy, which makes it possible to configure
960 dnsmasq to use a DHCP relay agent as a full proxy, with
961 all DHCP messages passing through the proxy. This is
962 useful if the relay adds extra information to the packets
963 it forwards, but cannot be configured with the RFC 5107
964 server-override option.
965
966 Added interface:<iface name> part to dhcp-range. The
967 semantics of this are very odd at first sight, but it
968 allows a single line of the form
969 dhcp-range=interface:virt0,192.168.0.4,192.168.0.200
970 to be added to dnsmasq configuration which then supplies
971 DHCP and DNS services to that interface, without affecting
972 what services are supplied to other interfaces and
973 irrespective of the existance or lack of
974 interface=<interface>
975 lines elsewhere in the dnsmasq configuration. The idea is
976 that such a line can be added automatically by libvirt
977 or equivalent systems, without disturbing any manual
978 configuration.
979
980 Similarly to the above, allow --enable-tftp=<interface>
981
982 Allow a TFTP root to be set separately for requests via
983 different interfaces, --tftp-root=<path>,<interface>
984
985 Correctly handle and log clashes between CNAMES and
986 DNS names being given to DHCP leases. This fixes a bug
987 which caused nonsense IP addresses to be logged. Thanks to
988 Sergei Zhirikov for finding and analysing the problem.
989
990 Tweak flush_log so as to avoid leaving the log
991 file in non-blocking mode. O_NONBLOCK is a property of the
992 file, not the process/descriptor.
993
994 Fix contrib/Solaris10/create_package
995 (/usr/man -> /usr/share/man) Thanks to Vita Batrla.
996
997 Fix a problem where, if a client got a lease, then went
998 to another subnet and got another lease, then moved back,
999 it couldn't resume the old lease, but would instead get
1000 a new address. Thanks to Leonardo Rodrigues for spotting
1001 this and testing the fix.
1002
1003 Fix weird bug which sometimes omitted certain characters
1004 from the start of quoted strings in dhcp-options. Thanks
1005 to Dayton Turner for spotting the problem.
1006
1007 Add facility to redirect some domains to the standard
1008 upstream servers: this allows something like
1009 --server=/google.com/1.2.3.4 --server=/www.google.com/#
1010 which will send queries for *.google.com to 1.2.3.4,
1011 except *www.google.com which will be forwarded as usual.
1012 Thanks to AJ Weber for prompting this addition.
1013
1014 Improve the hash-algorithm used to generate IP addresses
1015 from MAC addresses during initial DHCP address
1016 allocation. This improves performance when large numbers
1017 of hosts with similar MAC addresses all try and get an IP
1018 address at the same time. Thanks to Paul Smith for his
1019 work on this.
1020
1021 Tweak DHCP code so that --bridge-interface can be used to
1022 select which IP alias of an interface should be used for
1023 DHCP purposes on Linux. If eth0 has an alias eth0:dhcp
1024 then adding --bridge-interface=eth0:dhcp,eth0 will use
1025 the address of eth0:dhcp to determine the correct subnet
1026 for DHCP address allocation. Thanks to Pawel Golaszewski
1027 for prompting this and Eric Cooper for further testing.
1028
1029 Add --dhcp-generate-names. Suggestion by Ferenc Wagner.
1030
1031 Tweak DNS server selection algorithm when there is more
1032 than one server available for a domain, eg.
1033 --server=/mydomain/1.1.1.1
1034 --server=/mydomain/2.2.2.2
1035 Thanks to Alberto Cuesta-Canada for spotting a weakness
1036 here.
1037
1038 Add --max-ttl. Thanks to Fredrik Ringertz for the patch.
1039
1040 Allow --log-facility=- to force all logging to
1041 stderr. Suggestion from Clemens Fischer.
1042
1043 Fix regression which caused configuration like
1044 --address=/.domain.com/1.2.3.4 to be rejected. The dot to the
1045 left of the domain has been implied and not required for a
1046 long time, but it should be accepted for backward
1047 compatibility. Thanks to Andrew Burcin for spotting this.
1048
1049 Add --rebind-domain-ok and --rebind-localhost-ok.
1050 Suggestion from Clemens Fischer.
1051
1052 Log replies to queries of type TXT, when --log-queries
1053 is set.
1054
1055 Fix compiler warnings when compiled with -DNO_DHCP. Thanks
1056 to Shantanu Gadgil for the patch.
1057
1058 Updated French translation. Thanks to Gildas Le Nadan.
1059
1060 Updated Polish translation. Thanks to Jan Psota.
1061
1062 Updated German translation. Thanks to Matthias Andree.
1063
1064 Added contrib/static-arp, thanks to Darren Hoo.
1065
1066 Fix corruption of the domain when a name from /etc/hosts
1067 overrides one supplied by a DHCP client. Thanks to Fedor
1068 Kozhevnikov for spotting the problem.
1069
1070 Updated Spanish translation. Thanks to Chris Chatham.
1071
1072
Simon Kelley316e2732010-01-22 20:16:09 +00001073version 2.52
1074 Work around a Linux kernel bug which insists that the
1075 length of the option passed to setsockopt must be at least
1076 sizeof(int) bytes, even if we're calling SO_BINDTODEVICE
1077 and the device name is "lo". Note that this is fixed
1078 in kernel 2.6.31, but the workaround is harmless and
1079 allows earlier kernels to be used. Also fix dnsmasq
1080 bug which reported the wrong address when this failed.
1081 Thanks to Fedor for finding this.
1082
1083 The API for IPv6 PKTINFO changed around Linux kernel
1084 2.6.14. Workaround the case where dnsmasq is compiled
1085 against newer headers, but then run on an old kernel:
1086 necessary for some *WRT distros.
1087
1088 Re-read the set of network interfaces when re-loading
1089 /etc/resolv.conf if --bind-interfaces is not set. This
1090 handles the case that loopback interfaces do not exist
1091 when dnsmasq is first started.
1092
1093 Tweak the PXE code to support port 4011. This should
1094 reduce broadcasts and make things more reliable when other
1095 servers are around. It also improves inter-operability
1096 with certain clients.
1097
1098 Make a pxe-service configuration with no filename or boot
1099 service type legal: this does a local boot. eg.
1100 pxe-service=x86PC, "Local boot"
1101
1102 Be more conservative in detecting "A for A"
1103 queries. Dnsmasq checks if the name in a type=A query looks
1104 like a dotted-quad IP address and answers the query itself
1105 if so, rather than forwarding it. Previously dnsmasq
1106 relied in the library function inet_addr() to convert
1107 addresses, and that will accept some things which are
1108 confusing in this context, like 1.2.3 or even just
1109 1234. Now we only do A for A processing for four decimal
1110 numbers delimited by dots.
1111
1112 A couple of tweaks to fix compilation on Solaris. Thanks
1113 to Joel Macklow for help with this.
1114
1115 Another Solaris compilation tweak, needed for Solaris
1116 2009.06. Thanks to Lee Essen for that.
1117
1118 Added extract packaging stuff from Lee Essen to
1119 contrib/Solaris10.
1120
1121 Increased the default limit on number of leases to 1000
1122 (from 150). This is mainly a defence against DoS attacks,
1123 and for the average "one for two class C networks"
1124 installation, IP address exhaustion does that just as
1125 well. Making the limit greater than the number of IP
1126 addresses available in such an installation removes a
1127 surprise which otherwise can catch people out.
1128
1129 Removed extraneous trailing space in the value of the
1130 DNSMASQ_TIME_REMAINING DNSMASQ_LEASE_LENGTH and
1131 DNSMASQ_LEASE_EXPIRES environment variables. Thanks to
1132 Gildas Le Nadan for spotting this.
1133
1134 Provide the network-id tags for a DHCP transaction to
1135 the lease-change script in the environment variable
1136 DNSMASQ_TAGS. A good suggestion from Gildas Le Nadan.
1137
1138 Add support for RFC3925 "Vendor-Identifying Vendor
1139 Options". The syntax looks like this:
1140 --dhcp-option=vi-encap:<enterprise number>, .........
1141
1142 Add support to --dhcp-match to allow matching against
1143 RFC3925 "Vendor-Identifying Vendor Classes". The syntax
1144 looks like this:
1145 --dhcp-match=tag,vi-encap<enterprise number>, <value>
1146
1147 Add some application specific code to assist in
1148 implementing the Broadband forum TR069 CPE-WAN
1149 specification. The details are in contrib/CPE-WAN/README
1150
1151 Increase the default DNS packet size limit to 4096, as
1152 recommended by RFC5625 section 4.4.3. This can be
1153 reconfigured using --edns-packet-max if needed. Thanks to
1154 Francis Dupont for pointing this out.
1155
Simon Kelley8ef5ada2010-06-03 19:42:45 +01001156 Rewrite query-ids even for TSIG signed packets, since
Simon Kelley316e2732010-01-22 20:16:09 +00001157 this is allowed by RFC5625 section 4.5.
1158
1159 Use getopt_long by default on OS X. It has been supported
1160 since version 10.3.0. Thanks to Arek Dreyer for spotting
1161 this.
1162
1163 Added up-to-date startup configuration for MacOSX/launchd
1164 in contrib/MacOSX-launchd. Thanks to Arek Dreyer for
1165 providing this.
1166
1167 Fix link error when including Dbus but excluding DHCP.
1168 Thanks to Oschtan for the bug report.
1169
1170 Updated French translation. Thanks to Gildas Le Nadan.
1171
1172 Updated Polish translation. Thanks to Jan Psota.
1173
1174 Updated Spanish translation. Thanks to Chris Chatham.
1175
Simon Kelley8ef5ada2010-06-03 19:42:45 +01001176 Fixed confusion about domains, when looking up DHCP hosts
1177 in /etc/hosts. This could cause spurious "Ignoring
1178 domain..." messages. Thanks to Fedor Kozhevnikov for
1179 finding and analysing the problem.
Simon Kelley316e2732010-01-22 20:16:09 +00001180
Simon Kelley8ef5ada2010-06-03 19:42:45 +01001181
Simon Kelley1f15b812009-10-13 17:49:32 +01001182version 2.51
1183 Add support for internationalised DNS. Non-ASCII characters
1184 in domain names found in /etc/hosts, /etc/ethers and
1185 /etc/dnsmasq.conf will be correctly handled by translation to
1186 punycode, as specified in RFC3490. This function is only
1187 available if dnsmasq is compiled with internationalisation
1188 support, and adds a dependency on GNU libidn. Without i18n
1189 support, dnsmasq continues to be compilable with just
1190 standard tools. Thanks to Yves Dorfsman for the
1191 suggestion.
1192
1193 Add two more environment variables for lease-change scripts:
1194 First, DNSMASQ_SUPPLIED_HOSTNAME; this is set to the hostname
1195 supplied by a client, even if the actual hostname used is
1196 over-ridden by dhcp-host or dhcp-ignore-names directives.
1197 Also DNSMASQ_RELAY_ADDRESS which gives the address of
1198 a DHCP relay, if used.
1199 Suggestions from Michael Rack.
1200
1201 Fix regression which broke echo of relay-agent
1202 options. Thanks to Michael Rack for spotting this.
1203
1204 Don't treat option 67 as being interchangeable with
1205 dhcp-boot parameters if it's specified as
1206 dhcp-option-force.
1207
1208 Make the code to call scripts on lease-change compile-time
1209 optional. It can be switched off by editing src/config.h
1210 or building with "make COPTS=-DNO_SCRIPT".
1211
1212 Make the TFTP server cope with filenames from Windows/DOS
1213 which use '\' as pathname separator. Thanks to Ralf for
1214 the patch.
1215
1216 Updated Polish translation. Thanks to Jan Psota.
1217
1218 Warn if an IP address is duplicated in /etc/ethers. Thanks
1219 to Felix Schwarz for pointing this out.
1220
1221 Teach --conf-dir to take an option list of file suffices
1222 which will be ignored when scanning the directory. Useful
1223 for backup files etc. Thanks to Helmut Hullen for the
1224 suggestion.
1225
1226 Add new DHCP option named tftpserver-address, which
1227 corresponds to the third argument of dhcp-boot. This
1228 allows the complete functionality of dhcp-boot to be
1229 replicated with dhcp-option. Useful when using
1230 dhcp-optsfile.
1231
1232 Test which upstream nameserver to use every 10 seconds
1233 or 50 queries and not just when a query times out and
1234 is retried. This should improve performance when there
1235 is a slow nameserver in the list. Thanks to Joe for the
1236 suggestion.
1237
1238 Don't do any PXE processing, even for clients with the
1239 correct vendorclass, unless at least one pxe-prompt or
1240 pxe-service option is given. This stops dnsmasq
1241 interfering with proxy PXE subsystems when it is just
1242 the DHCP server. Thanks to Spencer Clark for spotting this.
1243
1244 Limit the blocksize used for TFTP transfers to a value
1245 which avoids packet fragmentation, based on the MTU of the
1246 local interface. Many netboot ROMs can't cope with
1247 fragmented packets.
1248
1249 Honour dhcp-ignore configuration for PXE and proxy-PXE
1250 requests. Thanks to Niels Basjes for the bug report.
1251
1252 Updated French translation. Thanks to Gildas Le Nadan.

Simon Kelley1f15b812009-10-13 17:49:32 +01001256 Fix security problem which allowed any host permitted to
Simon Kelley77e94da2009-08-31 17:32:17 +01001257 do TFTP to possibly compromise dnsmasq by remote buffer
1258 overflow when TFTP enabled. Thanks to Core Security
1259 Technologies and Iván Arce, Pablo Hernán Jorge, Alejandro
1260 Pablo Rodriguez, Martín Coco, Alberto Soliño Testa and
1261 Pablo Annetta. This problem has Bugtraq id: 36121
1262 and CVE: 2009-2957
1263
1264 Fix a problem which allowed a malicious TFTP client to
1265 crash dnsmasq. Thanks to Steve Grubb at Red Hat for
1266 spotting this. This problem has Bugtraq id: 36120 and
1267 CVE: 2009-2958

Simon Kelley03a97b62009-06-10 20:55:49 +01001270version 2.49
1271 Fix regression in 2.48 which disables the lease-change
1272 script. Thanks to Jose Luis Duran for spotting this.
1273
1274 Log TFTP "file not found" errors. These were not logged,
1275 since a normal PXELinux boot generates many of them, but
1276 the lack of the messages seems to be more confusing than
1277 routinely seeing them when there is no real error.
1278
1279 Update Spanish translation. Thanks to Chris Chatham.

Simon Kelley7622fc02009-06-04 20:32:05 +01001282version 2.48
1283 Archived the extensive, backwards, changelog to
1284 CHANGELOG.archive. The current changelog now runs from
1285 version 2.43 and runs conventionally.
Simon Kelley9e4abcb2004-01-22 19:47:41 +00001286
Simon Kelley7622fc02009-06-04 20:32:05 +01001287 Fixed bug which broke binding of servers to physical
1288 interfaces when interface names were longer than four
1289 characters. Thanks to MURASE Katsunori for the patch.
Simon Kelley9e4abcb2004-01-22 19:47:41 +00001290
Simon Kelley7622fc02009-06-04 20:32:05 +01001291 Fixed netlink code to check that messages come from the
1292 correct source, and not another userspace process. Thanks
1293 to Steve Grubb for the patch.
Simon Kelley9e4abcb2004-01-22 19:47:41 +00001294
Simon Kelley7622fc02009-06-04 20:32:05 +01001295 Maintainability drive: removed bug and missing feature
1296 workarounds for some old platforms. Solaris 9, OpenBSD
1297 older than 4.1, Glibc older than 2.2, Linux 2.2.x and
1298 DBus older than 1.1.x are no longer supported.
Simon Kelley9e4abcb2004-01-22 19:47:41 +00001299
Simon Kelley7622fc02009-06-04 20:32:05 +01001300 Don't read included configuration files more than once:
1301 allows complex configuration structures without problems.
Simon Kelley9e4abcb2004-01-22 19:47:41 +00001302
Simon Kelley7622fc02009-06-04 20:32:05 +01001303 Mark log messages from the various subsystems in dnsmasq:
1304 messages from the DHCP subsystem now have the ident string
1305 "dnsmasq-dhcp" and messages from TFTP have ident
1306 "dnsmasq-tftp". Thanks to Olaf Westrik for the patch.
Simon Kelley9e4abcb2004-01-22 19:47:41 +00001307
Simon Kelley7622fc02009-06-04 20:32:05 +01001308 Fix possible infinite DHCP protocol loop when an IP
1309 address nailed to a hostname (not a MAC address) and a
1310 host sometimes provides the name, sometimes not.
Simon Kelley9e4abcb2004-01-22 19:47:41 +00001311
Simon Kelley7622fc02009-06-04 20:32:05 +01001312 Allow --addn-hosts to take a directory: all the files
1313 in the directory are read. Thanks to Phil Cornelius for
1314 the suggestion.
Simon Kelley9e4abcb2004-01-22 19:47:41 +00001315
Simon Kelley7622fc02009-06-04 20:32:05 +01001316 Support --bridge-interface on all platforms, not just BSD.
Simon Kelley1ab84e22004-01-29 16:48:35 +00001317
Simon Kelley7622fc02009-06-04 20:32:05 +01001318 Added support for advanced PXE functions. It's now
1319 possible to define a prompt and menu options which will
1320 be displayed when a client PXE boots. It's also possible to
1321 hand-off booting to other boot servers. Proxy-DHCP, where
1322 dnsmasq just supplies the PXE information and another DHCP
1323 server does address allocation, is also allowed. See the
1324 --pxe-prompt and --pxe-service keywords. Thanks to
1325 Alkis Georgopoulos for the suggestion and Guilherme Moro
1326 and Michael Brown for assistance.
Simon Kelley1ab84e22004-01-29 16:48:35 +00001327
Simon Kelley7622fc02009-06-04 20:32:05 +01001328 Improvements to DHCP logging. Thanks to Tom Metro for
1329 useful suggestions.
1330
1331 Add ability to build dnsmasq without DHCP support. To do
1332 this, edit src/config.h or build with
1333 "make COPTS=-DNO_DHCP". Thanks to Mahavir Jain for the patch.
1334
1335 Added --test command-line switch - syntax check
1336 configuration files only.
Simon Kelley33820b72004-04-03 21:10:00 +01001337
Simon Kelley7622fc02009-06-04 20:32:05 +01001338 Updated French translation. Thanks to Gildas Le Nadan.

Simon Kelley73a08a22009-02-05 20:28:08 +00001340
1341version 2.47
1342 Updated French translation. Thanks to Gildas Le Nadan.
1343
1344 Fixed interface enumeration code to work on NetBSD
1345 5.0. Thanks to Roy Marples for the patch.
1346
1347 Updated config.h to use the same location for the lease
1348 file on NetBSD as the other *BSD variants. Also allow
1349 LEASEFILE and CONFFILE symbols to be overriden in CFLAGS.
1350
1351 Handle duplicate address detection on IPv6 more
1352 intelligently. In IPv6, an interface can have an address
1353 which is not usable, because it is still undergoing DAD
1354 (such addresses are marked "tentative"). Attempting to
1355 bind to an address in this state returns an error,
1356 EADDRNOTAVAIL. Previously, on getting such an error,
1357 dnsmasq would silently abandon the address, and never
1358 listen on it. Now, it retries once per second for 20
1359 seconds before generating a fatal error. 20 seconds should
1360 be long enough for any DAD process to complete, but can be
1361 adjusted in src/config.h if necessary. Thanks to Martin
1362 Krafft for the bug report.
1363
1364 Add DBus introspection. Patch from Jeremy Laine.
1365
1366 Update Dbus configuration file. Patch from Colin Walters.
1367 Fix for this bug:
1368 http://bugs.freedesktop.org/show_bug.cgi?id=18961
1369
1370 Support arbitrarily encapsulated DHCP options, suggestion
1371 and initial patch from Samium Gromoff. This is useful for
1372 (eg) gPXE, which expect all its private options to be
1373 encapsulated inside a single option 175. So, eg,
1374
1375 dhcp-option = encap:175, 190, "iscsi-client0"
1376 dhcp-option = encap:175, 191, "iscsi-client0-secret"
1377
1378 will provide iSCSI parameters to gPXE.
1379
1380 Enhance --dhcp-match to allow testing of the contents of a
1381 client-sent option, as well as its presence. This
1382 application in mind for this is RFC 4578
1383 client-architecture specifiers, but it's generally useful.
1384 Joey Korkames suggested the enhancement.
1385
1386 Move from using the IP_XMIT_IF ioctl to IP_BOUND_IF on
1387 OpenSolaris. Thanks to Bastian Machek for the heads-up.
1388
1389 No longer complain about blank lines in
1390 /etc/ethers. Thanks to Jon Nelson for the patch.
1391
1392 Fix binding of servers to physical devices, eg
1393 --server=/domain/1.2.3.4@eth0 which was broken from 2.43
1394 onwards unless --query-port=0 set. Thanks to Peter Naulls
1395 for the bug report.
1396
1397 Reply to DHCPINFORM requests even when the supplied ciaddr
1398 doesn't fall in any dhcp-range. In this case it's not
1399 possible to supply a complete configuration, but
1400 individually-configured options (eg PAC) may be useful.
1401
1402 Allow the source address of an alias to be a range:
1403 --alias=192.168.0.0,10.0.0.0,255.255.255.0 maps the whole
1404 subnet 192.168.0.0->192.168.0.255 to 10.0.0.0->10.0.0.255,
1405 as before.
1406 --alias=192.168.0.10-192.168.0.40,10.0.0.0,255.255.255.0
1407 maps only the 192.168.0.10->192.168.0.40 region. Thanks to
1408 Ib Uhrskov for the suggestion.
1409
1410 Don't dynamically allocate DHCP addresses which may break
1411 Windows. Addresses which end in .255 or .0 are broken in
1412 Windows even when using supernetting.
1413 --dhcp-range=192.168.0.1,192.168.1.254,255,255,254.0 means
1414 192.168.0.255 is a valid IP address, but not for Windows.
1415 See Microsoft KB281579. We therefore no longer allocate
1416 these addresses to avoid hard-to-diagnose problems.
1417
1418 Update Polish translation. Thanks to Jan Psota.
1419
1420 Delete the PID-file when dnsmasq shuts down. Note that by
1421 this time, dnsmasq is normally not running as root, so
1422 this will fail if the PID-file is stored in a root-owned
1423 directory; such failure is silently ignored. To take
1424 advantage of this feature, the PID-file must be stored in a
1425 directory owned and write-able by the user running
1426 dnsmasq.
Simon Kelley7622fc02009-06-04 20:32:05 +01001427
1428
1429version 2.46
1430 Allow --bootp-dynamic to take a netid tag, so that it may
1431 be selectively enabled. Thanks to Olaf Westrik for the
1432 suggestion.
1433
1434 Remove ISC-leasefile reading code. This has been
1435 deprecated for a long time, and last time I removed it, it
1436 ended up going back by request of one user. This time,
1437 it's gone for good; otherwise it would need to be
1438 re-worked to support multiple domains (see below).
1439
1440 Support DHCP clients in multiple DNS domains. This is a
1441 long-standing request. Clients are assigned to a domain
1442 based in their IP address.
1443
1444 Add --dhcp-fqdn flag, which changes behaviour if DNS names
1445 assigned to DHCP clients. When this is set, there must be
1446 a domain associated with each client, and only
1447 fully-qualified domain names are added to the DNS. The
1448 advantage is that the only the FQDN needs to be unique,
1449 so that two or more DHCP clients can share a hostname, as
1450 long as they are in different domains.
1451
1452 Set environment variable DNSMASQ_DOMAIN when invoking
1453 lease-change script. This may be useful information to
1454 have now that it's variable.
1455
1456 Tighten up data-checking code for DNS packet
1457 handling. Thanks to Steve Dodd who found certain illegal
1458 packets which could crash dnsmasq. No memory overwrite was
1459 possible, so this is not a security issue beyond the DoS
1460 potential.
1461
1462 Update example config dhcp option 47, the previous
1463 suggestion generated an illegal, zero-length,
1464 option. Thanks to Matthias Andree for finding this.
1465
1466 Rewrite hosts-file reading code to remove the limit of
1467 1024 characters per line. John C Meuser found this.
1468
1469 Create a net-id tag with the name of the interface on
1470 which the DHCP request was received.
1471
1472 Fixed minor memory leak in DBus code, thanks to Jeremy
1473 Laine for the patch.
1474
1475 Emit DBus signals as the DHCP lease database
1476 changes. Thanks to Jeremy Laine for the patch.
1477
1478 Allow for more that one MAC address in a dhcp-host
1479 line. This configuration tells dnsmasq that it's OK to
1480 abandon a DHCP lease of the fixed address to one MAC
1481 address, if another MAC address in the dhcp-host statement
1482 asks for an address. This is useful to give a fixed
1483 address to a host which has two network interfaces
1484 (say, a laptop with wired and wireless interfaces.)
1485 It's very important to ensure that only one interface
1486 at a time is up, since dnsmasq abandons the first lease
1487 and re-uses the address before the leased time has
1488 elapsed. John Gray suggested this.
1489
1490 Tweak the response to a DHCP request packet with a wrong
1491 server-id when --dhcp-authoritative is set; dnsmasq now
1492 returns a DHCPNAK, rather than silently ignoring the
1493 packet. Thanks to Chris Marget for spotting this
1494 improvement.
1495
1496 Add --cname option. This provides a limited alias
1497 function, usable for DHCP names. Thanks to AJ Weber for
1498 suggestions on this.
1499
1500 Updated contrib/webmin with latest version from Neil
1501 Fisher.
1502
1503 Updated Polish translation. Thanks to Jan Psota.
1504
1505 Correct the text names for DHCP options 64 and 65 to be
1506 "nis+-domain" and "nis+-servers".
1507
1508 Updated Spanish translation. Thanks to Chris Chatham.
1509
1510 Force re-reading of /etc/resolv.conf when an "interface
1511 up" event occurs.
1512
1513
1514version 2.45
1515 Fix total DNS failure in release 2.44 unless --min-port
1516 specified. Thanks to Steven Barth and Grant Coady for
1517 bugreport. Also reject out-of-range port spec, which could
1518 break things too: suggestion from Gilles Espinasse.
1519
1520
1521version 2.44
1522 Fix crash when unknown client attempts to renew a DHCP
1523 lease, problem introduced in version 2.43. Thanks to
1524 Carlos Carvalho for help chasing this down.
1525
1526 Fix potential crash when a host which doesn't have a lease
1527 does DHCPINFORM. Again introduced in 2.43. This bug has
1528 never been reported in the wild.
1529
1530 Fix crash in netlink code introduced in 2.43. Thanks to
1531 Jean Wolter for finding this.
1532
1533 Change implementation of min_port to work even if min-port
1534 is large.
1535
1536 Patch to enable compilation of latest Mac OS X. Thanks to
1537 David Gilman.
1538
1539 Update Spanish translation. Thanks to Christopher Chatham.
1540
1541
1542version 2.43
1543 Updated Polish translation. Thanks to Jan Psota.
1544
1545 Flag errors when configuration options are repeated
1546 illegally.
1547
1548 Further tweaks for GNU/kFreeBSD
1549
1550 Add --no-wrap to msgmerge call - provides nicer .po file
1551 format.
1552
1553 Honour lease-time spec in dhcp-host lines even for
1554 BOOTP. The user is assumed to known what they are doing in
1555 this case. (Hosts without the time spec still get infinite
1556 leases for BOOTP, over-riding the default in the
1557 dhcp-range.) Thanks to Peter Katzmann for uncovering this.
1558
1559 Fix problem matching relay-agent ids. Thanks to Michael
1560 Rack for the bug report.
1561
1562 Add --naptr-record option. Suggestion from Johan
1563 Bergquist.
1564
1565 Implement RFC 5107 server-id-override DHCP relay agent
1566 option.
1567
1568 Apply patches from Stefan Kruger for compilation on
1569 Solaris 10 under Sun studio.
1570
1571 Yet more tweaking of Linux capability code, to suppress
1572 pointless wingeing from kernel 2.6.25 and above.
1573
1574 Improve error checking during startup. Previously, some
1575 errors which occurred during startup would be worked
1576 around, with dnsmasq still starting up. Some were logged,
1577 some silent. Now, they all cause a fatal error and dnsmasq
1578 terminates with a non-zero exit code. The errors are those
1579 associated with changing uid and gid, setting process
1580 capabilities and writing the pidfile. Thanks to Uwe
1581 Gansert and the Suse security team for pointing out
1582 this improvement, and Bill Reimers for good implementation
1583 suggestions.
1584
1585 Provide NO_LARGEFILE compile option to switch off largefile
1586 support when compiling against versions of uclibc which
1587 don't support it. Thanks to Stephane Billiart for the patch.
1588
1589 Implement random source ports for interactions with
1590 upstream nameservers. New spoofing attacks have been found
1591 against nameservers which do not do this, though it is not
1592 clear if dnsmasq is vulnerable, since to doesn't implement
1593 recursion. By default dnsmasq will now use a different
1594 source port (and socket) for each query it sends
1595 upstream. This behaviour can suppressed using the
1596 --query-port option, and the old default behaviour
1597 restored using --query-port=0. Explicit source-port
1598 specifications in --server configs are still honoured.
1599
1600 Replace the random number generator, for better
1601 security. On most BSD systems, dnsmasq uses the
1602 arc4random() RNG, which is secure, but on other platforms,
1603 it relied on the C-library RNG, which may be
1604 guessable and therefore allow spoofing. This release
1605 replaces the libc RNG with the SURF RNG, from Daniel
1606 J. Berstein's DJBDNS package.
1607
1608 Don't attempt to change user or group or set capabilities
1609 if dnsmasq is run as a non-root user. Without this, the
1610 change from soft to hard errors when these fail causes
1611 problems for non-root daemons listening on high
1612 ports. Thanks to Patrick McLean for spotting this.
1613
1614 Updated French translation. Thanks to Gildas Le Nadan.
