Giacomo Tazzari797a7af2013-04-22 13:16:37 +01001version 2.67
2 Fix crash if upstream server returns SERVFAIL when
3 --conntrack in use. Thanks to Giacomo Tazzari for finding
4 this and supplying the patch.
Simon Kelleyaa63a212013-04-22 15:01:52 +01005
6 Repair regression in 2.64. That release stopped sending
7 lease-time information in the reply to DHCPINFORM
8 requests, on the correct grounds that it was a standards
9 violation. However, this broke the dnsmasq-specific
10 dhcp_lease_time utility. Now, DHCPINFORM returns
11 lease-time only if it's specifically requested
12 (maintaining standards) and the dhcp_lease_time utility
13 has been taught to ask for it (restoring functionality).
Simon Kelley86e92f92013-04-23 11:31:39 +010014
15 Fix --dhcp-match, --dhcp-vendorclass and --dhcp-userclass
16 to work with BOOTP and well as DHCP. Thanks to Peter
17 Korsgaard for spotting the problem.
Simon Kelley2bb73af2013-04-24 17:38:19 +010018
19 Add --synth-domain. Thanks to Vishvananda Ishaya for
20 suggesting this.
Simon Kelleyd5052fb2013-04-25 12:44:20 +010021
22 Fix failure to compile ipset.c if old kernel headers are
23 in use. Thanks to Eugene Rudoy for pointing this out.
Simon Kelley3f2873d2013-05-14 11:28:47 +010024
25 Handle IPv4 interface-address labels in Linux. These are
26 often used to emulate the old IP-alias addresses. Before,
27 using --interface=eth0 would service all the addresses of
28 eth0, including ones configured as aliases, which appear
29 in ifconfig as eth0:0. Now, only addresses with the label
30 eth0 are active. This is not backwards compatible: if you
31 want to continue to bind the aliases too, you need to add
32 eg. --interface=eth0:0 to the config.
Giacomo Tazzari797a7af2013-04-22 13:16:37 +010033
Simon Kelleycfcad422013-05-17 11:32:03 +010034 Fix "failed to set SO_BINDTODEVICE on DHCP socket: Socket
35 operation on non-socket" error on startup with
36 configurations which have exactly one --interface option
37 and do RA but _not_ DHCPv6. Thanks to Trever Adams for the
38 bug report.
Giacomo Tazzari797a7af2013-04-22 13:16:37 +010039
Simon Kelley115ac3e2013-05-20 11:28:32 +010040 Generalise --interface-name to cope with IPv6 addresses
41 and multiple addresses per interface per address family.
42
Simon Kelley3e8ed782013-05-29 14:31:33 +010043 Fix option parsing for --dhcp-host, which was generating a
44 spurious error when all seven possible items were
45 included. Thanks to Zhiqiang Wang for the bug report.
Simon Kelleybaa80ae2013-05-29 16:32:07 +010046
47 Remove restriction on prefix-length in --auth-zone. Thanks
48 to Toke Hoiland-Jorgensen for suggesting this.
49
Marcelo Salhab Brogliato0da5e892013-05-31 11:49:06 +010050 Log when the maximum number of concurrent DNS queries is
51 reached. Thanks to Marcelo Salhab Brogliato for the patch.
52
Simon Kelleye2ba0df2013-05-31 17:04:25 +010053 If wildcards are used in --interface, don't assume that
54 there will only ever be one available interface for DHCP
55 just because there is one at start-up. More may appear, so
56 we can't use SO_BINDTODEVICE. Thanks to Natrio for the bug
57 report.
58
Simon Kelleyb4b93082013-06-19 10:31:23 +010059 Increase timeout/number of retries in TFTP to accomodate
60 AudioCodes Voice Gateways doing streaming writes to flash.
61 Thanks to Damian Kaczkowski for spotting the problem.
62
Simon Kelley625ac282013-07-02 21:19:32 +010063 Fix crash with empty DHCP string options when adding zero
Simon Kelley3953dcc2013-07-03 20:40:45 +010064 terminator. Thanks to Patrick McLean for the bug report.
Simon Kelley625ac282013-07-02 21:19:32 +010065
Kyle Mesteryd859ca22013-07-24 13:11:58 +010066 Allow hostnames to start with a number, as allowed in
67 RFC-1123. Thanks to Kyle Mestery for the patch.
68
Roy Marples3f3adae2013-07-25 16:22:46 +010069 Fixes to DHCP FQDN option handling: don't terminate FQDN
70 if domain not known and allow a FQDN option with blank
71 name to request that a FQDN option is returned in the
72 reply. Thanks to Roy Marples for the patch.
73
Simon Kelleyd9fb0be2013-07-25 21:47:17 +010074 Make --clear-on-reload apply to setting upstream servers
75 via DBus too.
76
Simon Kelleyef1a94a2013-07-26 13:59:03 +010077 When the address which triggered the construction of an
78 advertised IPv6 prefix disappears, continue to advertise
79 the prefix for up to 2 hours, with the preferred lifetime
80 set to zero. This satisfies RFC 6204 4.3 L-13 and makes
81 things work better if a prefix disappears without being
82 deprecated first. Thanks to Uwe Schindler for persuasively
83 arguing for this.
84
Simon Kelleyfc4c4fd2013-07-26 15:38:59 +010085 Fix MAC address enumeration on *BSD. Thanks to Brad Smith
86 for the bug report.
Simon Kelleyb4b93082013-06-19 10:31:23 +010087
Simon Kelley871d4562013-07-27 21:32:32 +010088 Support RFC-4242 information-refresh-time options in the
89 reply to DHCPv6 information-request. The lease time of the
90 smallest valid dhcp-range is sent. Thanks to Uwe Schindler
91 for suggesting this.
92
Simon Kelley8d030462013-07-29 15:41:26 +010093 Add --force-fast-ra option. Another thanks to Uwe Schindler.
94
Simon Kelleyedf0bde2013-07-29 17:21:48 +010095 Make --listen-address higher priority than --except-interface
96 in all circumstances. Thanks to Thomas Hood for the bugreport.
97
Simon Kelley871d4562013-07-27 21:32:32 +010098
Simon Kelley333b2ce2013-01-07 21:46:03 +000099version 2.66
100 Add the ability to act as an authoritative DNS
101 server. Dnsmasq can now answer queries from the wider 'net
102 with local data, as long as the correct NS records are set
103 up. Only local data is provided, to avoid creating an open
104 DNS relay. Zone transfer is supported, to allow secondary
105 servers to be configured.
106
107 Add "constructed DHCP ranges" for DHCPv6. This is intended
108 for IPv6 routers which get prefixes dynamically via prefix
109 delegation. With suitable configuration, stateful DHCPv6
110 and RA can happen automatically as prefixes are delegated
111 and then deprecated, without having to re-write the
112 dnsmasq configuration file or restart the daemon. Thanks to
113 Steven Barth for extensive testing and development work on
114 this idea.
Simon Kelley71c73ac2013-01-08 21:22:24 +0000115
116 Fix crash on startup on Solaris 11. Regression probably
Simon Kelley22ce5502013-01-22 13:53:04 +0000117 introduced in 2.61. Thanks to Geoff Johnstone for the
118 patch.
119
120 Add code to make behaviour for TCP DNS requests that same
121 as for UDP requests, when a request arrives for an allowed
122 address, but via a banned interface. This change is only
123 active on Linux, since the relevant API is missing (AFAIK)
124 on other platforms. Many thanks to Tomas Hozza for
125 spotting the problem, and doing invaluable discovery of
126 the obscure and undocumented API required for the solution.
Simon Kelleya21e27b2013-02-17 16:41:35 +0000127
128 Don't send the default DHCP option advertising dnsmasq as
129 the local DNS server if dnsmasq is configured to not act
130 as DNS server, or it's configured to a non-standard port.
Simon Kelleydd1721c2013-02-18 21:04:04 +0000131
132 Add DNSMASQ_CIRCUIT_ID, DNSMASQ_SUBCRIBER_ID,
133 DNSMASQ_REMOTE_ID variables to the environment of the
Simon Kelley3d77c042013-03-22 10:03:50 +0000134 lease-change script (and the corresponding Lua). These hold
Simon Kelleydd1721c2013-02-18 21:04:04 +0000135 information inserted into the DHCP request by a DHCP relay
136 agent. Thanks to Lakefield Communications for providing a
137 bounty for this addition.
138
Simon Kelley4038ae22013-02-19 16:47:07 +0000139 Fixed crash, introduced in 2.64, whilst handling DHCPv6
140 information-requests with some common configurations.
141 Thanks to Robert M. Albrecht for the bug report and
142 chasing the problem.
143
Jason A. Donenfeld13d86c72013-02-22 18:20:53 +0000144 Add --ipset option. Thanks to Jason A. Donenfeld for the
145 patch.
146
Simon Kelleyc7961072013-02-28 15:17:58 +0000147 Don't erroneously reject some option names in --dhcp-match
Simon Kelley3d77c042013-03-22 10:03:50 +0000148 options. Thanks to Benedikt Hochstrasser for the bug report.
Simon Kelley49333cb2013-03-15 20:30:51 +0000149
150 Allow a trailing '*' wildcard in all interface-name
151 configurations. Thanks to Christian Parpart for the patch.
Simon Kelleyc7961072013-02-28 15:17:58 +0000152
Simon Kelley56a11422013-04-02 17:02:58 +0100153 Handle the situation where libc headers define
154 SO_REUSEPORT, but the kernel in use doesn't, to cope with
155 the introduction of this option to Linux. Thanks to Rich
156 Felker for the bug report.
157
Simon Kelleycd1e04a2013-04-02 20:11:48 +0100158 Update Polish translation. Thanks to Jan Psota.
Simon Kelley0b0a73c2013-04-11 14:07:02 +0100159
160 Fix crash if the configured DHCP lease limit is
161 reached. Regression occurred in 2.61. Thanks to Tsachi for
162 the bug report.
Simon Kelleycd1e04a2013-04-02 20:11:48 +0100163
Simon Kelley834f36f2013-04-17 13:52:49 +0100164 Update the French translation. Thanks to Gildas le Nadan.
165
Simon Kelley49333cb2013-03-15 20:30:51 +0000166
Simon Kelleyee86ce62012-12-07 11:54:46 +0000167version 2.65
168 Fix regression which broke forwarding of queries sent via
169 TCP which are not for A and AAAA and which were directed to
170 non-default servers. Thanks to Niax for the bug report.
171
Simon Kelleyb5a8dd12012-12-10 11:37:25 +0000172 Fix failure to build with DHCP support excluded. Thanks to
173 Gustavo Zacarias for the patch.
Simon Kelley1d6c6392012-12-14 11:19:36 +0000174
175 Fix nasty regression in 2.64 which completely broke cacheing.
Simon Kelleyb5a8dd12012-12-10 11:37:25 +0000176
177
Simon Kelley2e34ac12012-08-29 14:15:25 +0100178version 2.64
179 Handle DHCP FQDN options with all flag bits zero and
180 --dhcp-client-update set. Thanks to Bernd Krumbroeck for
181 spotting the problem.
182
Simon Kelley12d71ed2012-08-30 15:16:41 +0100183 Finesse the check for /etc/hosts names which conflict with
184 DHCP names. Previously a name/address pair in /etc/hosts
185 which didn't match the name/address of a DHCP lease would
186 generate a warning. Now that only happesn if there is not
187 also a match. This allows multiple addresses for a name in
188 /etc/hosts with one of them assigned via DHCP.
189
Simon Kelley4d0f5b42012-09-05 23:29:30 +0100190 Fix broken vendor-option processing for BOOTP. Thanks to
191 Hans-Joachim Baader for the bug report.
192
Simon Kelleydfb23b32012-09-18 21:44:47 +0100193 Don't report spurious netlink errors, regression in
194 2.63. Thanks to Vladislav Grishenko for the patch.
195
Simon Kelley2b127a12012-09-18 21:51:22 +0100196 Flag DHCP or DHCPv6 in starup logging. Thanks to
197 Vladislav Grishenko for the patch.
198
Simon Kelley295a54e2012-12-01 21:02:15 +0000199 Add SetServersEx method in DBus interface. Thanks to Dan
Simon Kelleyfaafb3f2012-09-20 14:17:39 +0100200 Williams for the patch.
201
Simon Kelley295a54e2012-12-01 21:02:15 +0000202 Add SetDomainServers method in DBus interface. Thanks to
203 Roy Marples for the patch.
204
Simon Kelley289a2532012-09-20 15:29:35 +0100205 Fix build with later Lua libraries. Thansk to Cristian
206 Rodriguez for the patch.
Simon Kelley2e34ac12012-08-29 14:15:25 +0100207
Simon Kelley1d860412012-09-20 20:48:04 +0100208 Add --max-cache-ttl option. Thanks to Dennis Kaarsemaker
209 for the patch.
210
Simon Kelleye4807d82012-09-27 21:52:26 +0100211 Fix breakage of --host-record parsing, resulting in
212 infinte loop at startup. Regression in 2.63. Thanks to
213 Haim Gelfenbeyn for spotting this.
214
Simon Kelley20223102012-10-15 10:41:17 +0100215 Set SO_REUSEADDRESS and SO_V6ONLY options on the DHCPv6
216 socket, this allows multiple instances of dnsmasq on a
217 single machine, in the same way as for DHCPv4. Thanks to
218 Gene Czarcinski and Vladislav Grishenko for work on this.
219
Simon Kelleybe6cfb42012-10-16 20:38:31 +0100220 Fix DHCPv6 to do access control correctly when it's
221 configured with --listen-address. Thanks to
222 Gene Czarcinski for sorting this out.
223
Simon Kelley819ff4d2012-10-21 18:25:12 +0100224 Add a "wildcard" dhcp-range which works for any IPv6
225 subnet, --dhcp-range=::,static Useful for Stateless
226 DHCPv6. Thanks to Vladislav Grishenko for the patch.
227
Simon Kelleyd1a59752012-11-05 16:50:30 +0000228 Don't include lease-time in DHCPACK replies to DHCPINFORM
229 queries, since RFC-2131 says we shouldn't. Thanks to
230 Wouter Ibens for pointing this out.
Simon Kelley8e4b8792012-11-14 14:12:56 +0000231
232 Makefile tweak to do dependency checking on header files.
233 Thanks to Johan Peeters for the patch.
Simon Kelleyd89fb4e2012-12-01 21:21:13 +0000234
235 Check interface for outgoing unsolicited router
236 advertisements, rather than relying on interface address
237 configuration. Thanks to Gene Czarinski for the patch.
Simon Kelley29d28dd2012-12-03 14:05:59 +0000238
239 Handle better attempts to transmit on interfaces which are
240 still doing DAD, and specifically do not just transmit
241 without setting source address and interface, since this
242 can cause very puzzling effects when a router
243 advertisement goes astray. Thanks again to Gene Czarinski.
244
245 Get RA timers right when there is more than one
246 dhcp-range on a subnet.
Simon Kelley289a2532012-09-20 15:29:35 +0100247
Simon Kelleyd1a59752012-11-05 16:50:30 +0000248
Simon Kelley078a6302012-06-07 13:56:23 +0100249version 2.63
250 Do duplicate dhcp-host address check in --test mode.
251
Simon Kelley8b3ae2f2012-06-13 13:43:49 +0100252 Check that tftp-root directories are accessible before
253 start-up. Thanks to Daniel Veillard for the initial patch.
254
255 Allow more than one --tfp-root flag. The per-interface
256 stuff is pointless without that.
257
Simon Kelley54dd3932012-06-20 11:23:38 +0100258 Add --bind-dynamic. A hybrid mode between the default and
259 --bind-interfaces which copes with dynamically created
260 interfaces.
Simon Kelley6b617c02012-06-29 21:15:42 +0100261
262 A couple of fixes to the build system for Android. Thanks
263 to Metin Kaya for the patches.
Simon Kelley54dd3932012-06-20 11:23:38 +0100264
Simon Kelley8bc4cec2012-07-03 21:04:11 +0100265 Remove the interface:<interface> argument in --dhcp-range, and
266 the interface argument to --enable-tftp. These were a
267 still-born attempt to allow automatic isolated
268 configuration by libvirt, but have never (to my knowledge)
269 been used, had very strange semantics, and have been
270 superceded by other mechanisms.
271
Simon Kelleyc4a7f902012-07-12 20:52:12 +0100272 Fixed bug logging filenames when duplicate dhcp-host
273 addresses are found. Thanks to John Hanks for the patch.
274
Simon Kelley611ebc52012-07-16 16:23:46 +0100275 Fix regression in 2.61 which broke caching of CNAME
276 chains. Thanks to Atul Gupta for the bug report.
277
Simon Kelleyb2714462012-07-17 12:09:26 +0100278 Allow the target of a --cname flag to be another --cname.
Simon Kelley611ebc52012-07-16 16:23:46 +0100279
Simon Kelley42243212012-07-20 15:19:18 +0100280 Teach DHCPv6 about the RFC 4242 information-refresh-time
281 option, and add parsing if the minutes, hours and days
282 format for options. Thanks to Francois-Xavier Le Bail for
283 the suggestion.
284
285 Allow "w" (for week) as multiplier in lease times, as well
286 as seconds, minutes, hours and days. Álvaro Gámez Machado
287 spotted the ommission.
Simon Kelleyc4c04882012-08-06 20:09:15 +0100288
289 Update French translation. Thanks to Gildas Le Nadan.
Simon Kelley42243212012-07-20 15:19:18 +0100290
Simon Kelleyad094272012-08-10 17:10:54 +0100291 Allow a DBus service name to be given with --enable-dbus
292 which overrides the default,
293 uk.org.thekelleys.dnsmasq. Thanks to Mathieu
294 Trudel-Lapierre for the patch.
295
Simon Kelleyfd05f122012-08-12 17:48:50 +0100296 Set the "prefix on-link" bit in Router
297 Advertisements. Thanks to Gui Iribarren for the patch.
298
Simon Kelley078a6302012-06-07 13:56:23 +0100299
Simon Kelley8358e0f2012-04-29 21:53:09 +0100300version 2.62
301 Update German translation. Thanks to Conrad Kostecki.
302
Simon Kelleyf632e562012-05-12 15:05:34 +0100303 Cope with router-solict packets wich don't have a valid
304 source address. Thanks to Vladislav Grishenko for the patch.
305
Simon Kelley919dd7c2012-05-12 15:23:09 +0100306 Fixed bug which caused missing periodic router
307 advertisements with some configurations. Thanks to
308 Vladislav Grishenko for the patch.
309
Simon Kelleyc64b7f62012-05-18 10:19:59 +0100310 Fixed bug which broke DHCPv6/RA with prefix lengths
311 which are not divisible by 8. Thanks to Andre Coetzee
312 for spotting this.
313
Simon Kelley18c63ef2012-05-21 14:34:15 +0100314 Fix non-response to router-solicitations when
315 router-advertisement configured, but DHCPv6 not
316 configured. Thanks to Marien Zwart for the patch.
317
Simon Kelley9f7f3b12012-05-28 21:39:57 +0100318 Add --dns-rr, to allow arbitrary DNS resource records.
319
Simon Kelley5ae34bf2012-06-04 21:14:03 +0100320 Fixed bug which broke RA scheduling when an interface had
321 two addresses in the same network. Thanks to Jim Bos for
322 his help nailing this.
323
Simon Kelleyeabc6dd2012-03-07 20:28:20 +0000324version 2.61
325 Re-write interface discovery code on *BSD to use
326 getifaddrs. This is more portable, more straightforward,
327 and allows us to find the prefix length for IPv6
328 addresses.
329
Simon Kelley01d1b8d2012-03-28 21:37:25 +0100330 Add ra-names, ra-stateless and slaac keywords for DHCPv6.
331 Dnsmasq can now synthesise AAAA records for dual-stack
332 hosts which get IPv6 addresses via SLAAC. It is also now
333 possible to use SLAAC and stateless DHCPv6, and to
334 tell clients to use SLAAC addresses as well as DHCP ones.
335 Thanks to Dave Taht for help with this.
Simon Kelley7023e382012-03-09 12:05:49 +0000336
Simon Kelley8b372702012-03-09 17:45:10 +0000337 Add --dhcp-duid to allow DUID-EN uids to be used.
338
Simon Kelley8643ec72012-03-12 20:04:14 +0000339 Explicity send DHCPv6 replies to the correct port, instead
340 of relying on clients to send requests with the correct
341 source address, since at least one client in the wild gets
Simon Kelley8358e0f2012-04-29 21:53:09 +0100342 this wrong. Thanks to Conrad Kostecki for help tracking
Simon Kelley8643ec72012-03-12 20:04:14 +0000343 this down.
Simon Kelleyeabc6dd2012-03-07 20:28:20 +0000344
Simon Kelley8643ec72012-03-12 20:04:14 +0000345 Send a preference value of 255 in DHCPv6 replies when
346 --dhcp-authoritative is in effect. This tells clients not

348
349 Better logging of DHCPv6 options.
350
Simon Kelleye759d422012-03-16 13:18:57 +0000351 Add --host-record. Thanks to Rob Zwissler for the
352 suggestion.
353
Simon Kelleya9530962012-03-20 22:07:35 +0000354 Invoke the DHCP script with action "tftp" when a TFTP file
355 transfer completes. The size of the file, address to which
356 it was sent and complete pathname are supplied. Note that
357 version 2.60 introduced some script incompatibilties
358 associated with DHCPv6, and this is a further change. To
359 be safe, scripts should ignore unknown actions, and if
360 not IPv6-aware, should exit if the environment
361 variable DNSMASQ_IAID is set. The use-case for this is
362 to track netboot/install. Suggestion from Shantanu
363 Gadgil.
364
365 Update contrib/port-forward/dnsmasq-portforward to reflect
366 the above.
367
368 Set the environment variable DNSMASQ_LOG_DHCP when running
369 the script id --log-dhcp is in effect, so that script can
Simon Kelley52d4abf2012-03-21 21:39:48 +0000370 taylor their logging verbosity. Suggestion from Malte
371 Forkel.
372
373 Arrange that addresses specified with --listen-address
374 work even if there is no interface carrying the
375 address. This is chiefly useful for IPv4 loopback
376 addresses, where any address in 127.0.0.0/8 is a valid
377 loopback address, but normally only 127.0.0.1 appears on
378 the lo interface. Thanks to Mathieu Trudel-Lapierre for
379 the idea and initial patch.
Simon Kelleya9530962012-03-20 22:07:35 +0000380
Simon Kelley7d2b5c92012-03-23 10:00:02 +0000381 Fix crash, introduced in 2.60, when a DHCPINFORM is
382 received from a network which has no valid dhcp-range.
383 Thanks to Stephane Glondu for the bug report.
384
Simon Kelleyc8257542012-03-28 21:15:41 +0100385 Add a new DHCP lease time keyword, "deprecated" for
386 --dhcp-range. This is only valid for IPv6, and sets the
387 preffered lease time for both DHCP and RA to zero. The
388 effect is that clients can continue to use the address
389 for existing connections, but new connections will use
390 other addresses, if they exist. This makes hitless
391 renumbering at least possible.
392
393 Fix bug in address6_available() which caused DHCPv6 lease
Simon Kelley8358e0f2012-04-29 21:53:09 +0100394 aquisition to fail if more than one dhcp-range in use.

Simon Kelley1023dcb2012-04-09 18:00:08 +0100403 Don't cache data from non-recursive nameservers, since it

Simon Kelleyc72daea2012-01-05 21:33:27 +0000435 Fix DHCP when using --listen-address with an IP address
436 which is not the primary address of an interface.
437
438 Add --dhcp-client-update option.
439
440 Add Lua integration. Dnsmasq can now execute a DHCP
441 lease-change script written in Lua. This needs to be
442 enabled at compile time by setting HAVE_LUASCRIPT in
443 src/config.h or running "make COPTS=-DHAVE_LUASCRIPT"
444 Thanks to Jan-Piet Mens for the idea and proof-of-concept
445 implementation.
446
447 Tidied src/config.h to distinguish between
448 platform-dependent compile-time options which are selected
449 automatically, and builder-selectable compile time
450 options. Document the latter better, and describe how to
451 set them from the make command line.
452
453 Tidied up IPPROTO_IP/SOL_IP (and IPv6 equivalent)
454 confusion. IPPROTO_IP works everywhere now.
455
456 Set TOS on DHCP sockets, this improves things on busy
457 wireless networks. Thanks to Dave Taht for the patch.

Simon Kelleya2761752012-01-18 16:07:21 +0000462 Improve start-up speed when reading large hosts files
463 containing many distinct addresses.
464
465 Fix problem if dnsmasq is started without the stdin,
466 stdout and stderr file descriptors open. This can manifest
467 itself as 100% CPU use. Thanks to Chris Moore for finding
468 this.
469
Simon Kelley9bbc8872012-02-09 21:33:09 +0000470 Fix shell-scripting bug in bld/pkg-wrapper. Thanks to
471 Mark Mitchell for the patch.
472
Simon Kelley751d6f42012-02-10 15:24:51 +0000473 Allow the TFP server or boot server in --pxe-service, to
474 be a domain name instead of an IP address. This allows for
475 round-robin to multiple servers, in the same way as
476 --dhcp-boot. A good suggestion from Cristiano Cumer.
477
Simon Kelleyfdacfb02012-02-28 15:20:25 +0000478 Support BUILDDIR variable in the Makefile. Allows builds
479 for multiple archs from the same source tree with eg.
480 make BUILDDIR=linux (relative to dnsmasq tree)
481 make BUILDDIR=/tmp/openbsd (absolute path)
Simon Kelleye5ffdb92012-02-13 14:19:25 +0000482 If BUILDDIR is not set, compilation happens in the src
Simon Kelleyb36ae192012-02-13 12:54:34 +0000483 directory, as before. Suggestion from Mark Mitchell.
484
Simon Kelleyfdacfb02012-02-28 15:20:25 +0000485 Support DHCPv6. Support is there for the sort of things
486 the existing v4 server does, including tags, options,
487 static addresses and relay support. Missing is prefix
488 delegation, which is probably not required in the dnsmasq
489 niche, and an easy way to accept prefix delegations from
490 an upstream DHCPv6 server, which is. Future plans include
491 support for DHCPv6 router option and MAC address option
492 (to make selecting clients by MAC address work like IPv4).
493 These will be added as the standards mature.
494 This code has been tested, but this is the first release,
495 so don't bet the farm on it just yet. Many thanks to all
496 testers who have got it this far.
Simon Kelley1adadf52012-02-13 22:15:58 +0000497
Simon Kelleyac8540c2012-02-26 20:57:31 +0000498 Support IPv6 router advertisements. This is a
499 simple-minded implementation, aimed at providing the
500 vestigial RA needed to go alongside IPv6. Is picks up
501 configuration from the DHCPv6 conf, and should just need
502 enabling with --enable-ra.
503
Simon Kelley552af8b2012-02-29 20:10:31 +0000504 Fix long-standing wrinkle with --localise-queries that
505 could result in wrong answers when DNS packets arrive
506 via an interface other than the expected one. Thanks to
507 Lorenzo Milesi and John Hanks for spotting this one.
Simon Kelley71ee7ee2012-03-03 18:06:49 +0000508

512
513
Simon Kelleyc72daea2012-01-05 21:33:27 +0000514version 2.59
515 Fix regression in 2.58 which caused failure to start up
516 with some combinations of dnsmasq config and IPv6 kernel
517 network config. Thanks to Brielle Bruns for the bug
518 report.
519
520 Improve dnsmasq's behaviour when network interfaces are
521 still doing duplicate address detection (DAD). Previously,
522 dnsmasq would wait up to 20 seconds at start-up for the
523 DAD state to terminate. This is broken for bridge
524 interfaces on recent Linux kernels, which don't start DAD
525 until the bridge comes up, and so can take arbitrary
526 time. The new behaviour lets dnsmasq poll for an arbitrary
527 time whilst providing service on other interfaces. Thanks
528 to Stephen Hemminger for pointing out the problem.
Simon Kelley74c95c22011-10-19 09:33:39 +0100529
530
Simon Kelley7de060b2011-08-26 17:24:52 +0100531version 2.58
532 Provide a definition of the SA_SIZE macro where it's
533 missing. Fixes build failure on openBSD.
534
535 Don't include a zero terminator at the end of messages
536 sent to /dev/log when /dev/log is a datagram socket.
537 Thanks to Didier Rabound for spotting the problem.
538
539 Add --dhcp-sequential-ip flag, to force allocation of IP
540 addresses in ascending order. Note that the default
541 pseudo-random mode is in general better but some
542 server-deployment applications need this.
543
544 Fix problem where a server-id of 0.0.0.0 is sent to a
545 client when a dhcp-relay is in use if a client renews a
546 lease after dnsmasq restart and before any clients on the
547 subnet get a new lease. Thanks to Mike Ruiz for assistance
548 in chasing this one down.
549
550 Don't return NXDOMAIN to an AAAA query if we have CNAME
551 which points to an A record only: NODATA is the correct
552 reply in this case. Thanks to Tom Fernandes for spotting
553 the problem.
554
555 Relax the need to supply a netmask in --dhcp-range for
556 networks which use a DHCP relay. Whilst this is still
557 desireable, in the absence of a netmask dnsmasq will use
558 a default based on the class (A, B, or C) of the address.
559 This should at least remove a cause of mysterious failure
560 for people using RFC1918 addresses and relays.
561
562 Add support for Linux conntrack connection marking. If
563 enabled with --conntrack, the connection mark for incoming
564 DNS queries will be copied to the outgoing connections
565 used to answer those queries. This allows clever firewall
566 and accounting stuff. Only available if dnsmasq is
567 compiled with HAVE_CONNTRACK and adds a dependency on
568 libnetfilter-conntrack. Thanks to Ed Wildgoose for the
569 initial idea, testing and sponsorship of this function.
570
571 Provide a sane error message when someone attempts to
572 match a tag in --dhcp-host.
573
574 Tweak the behaviour of --domain-needed, to avoid problems
575 with recursive nameservers downstream of dnsmasq. The new
576 behaviour only stops A and AAAA queries, and returns
577 NODATA rather than NXDOMAIN replies.
578
579 Efficiency fix for very large DHCP configurations, thanks
580 to James Gartrell and Mike Ruiz for help with this.
581
582 Allow the TFTP-server address in --dhcp-boot to be a
583 domain-name which is looked up in /etc/hosts. This can
584 give multiple IP addresses which are used round-robin,
585 thus doing TFTP server load-balancing. Thanks to Sushil
586 Agrawal for the patch.
587
588 When two tagged dhcp-options for a particular option
589 number are both valid, use the one which is valid without
590 a tag from the dhcp-range. Allows overriding of the value
591 of a DHCP option for a particular host as well as
592 per-network values. So
593 --dhcp-range=set:interface1,......
594 --dhcp-host=set:myhost,.....
595 --dhcp-option=tag:interface1,option:nis-domain,"domain1"
596 --dhcp-option=tag:myhost,option:nis-domain,"domain2"
597 will set the NIS-domain to domain1 for hosts in the range, but
598 override that to domain2 for a particular host.
599
600 Fix bug which resulted in truncated files and timeouts for
601 some TFTP transfers. The bug only occurs with netascii
602 transfers and needs an unfortunate relationship between
603 file size, blocksize and the number of newlines in the
604 last block before it manifests itself. Many thanks to
605 Alkis Georgopoulos for spotting the problem and providing
606 a comprehensive test-case.
607
608 Fix regression in TFTP server on *BSD platforms introduced
609 in version 2.56, due to confusion with sockaddr
Simon Kelleyde604c12012-10-19 09:50:01 +0100610 length. Many thanks to Loic Pefferkorn for finding this.
Simon Kelley7de060b2011-08-26 17:24:52 +0100611
612 Support scope-ids in IPv6 addresses of nameservers from
613 /etc/resolv.conf and in --server options. Eg
614 nameserver fe80::202:a412:4512:7bbf%eth0 or
615 server=fe80::202:a412:4512:7bbf%eth0. Thanks to
616 Michael Stapelberg for the suggestion.

622
Simon Kelley572b41e2011-02-18 18:11:18 +0000623version 2.57
624 Add patches to allow build under Android.
625
626 Provide our own header for the DNS protocol, rather than
627 relying on arpa/nameser.h. This has proved more or less
628 defective over the years and the final straw is that it's
629 effectively empty on Android.
630
631 Fix regression in 2.56 which caused hex constants in
632 configuration to be rejected if they contain the '*'
633 wildcard.
634
635 Correct wrong casts of arguments to ctype.h functions,
636 isdigit(), isxdigit() etc. Thanks to Matthias Andree for
637 spotting this.
638
639 Allow build with IDN support independently from i18n.
640 IDN support continues to be included automatically
641 when i18n is included.
642 'make COPTS=-DHAVE_IDN' is the magic incantation.
643
644 Modify check on extraneous command line junk (added in
645 2.56) so that it doesn't complain about extra _empty_
646 arguments. Otherwise this breaks libvirt.
647
648
Simon Kelley28866e92011-02-14 20:19:14 +0000649version 2.56
650 Add a patch to allow dnsmasq to get interface names right in a
651 Solaris zone. Thanks to Dj Padzensky for this.
652
653 Improve data-type parsing heuristics so that
654 --dhcp-option=option:domain-search,.
655 treats the value as a string and not an IP address.
656 Thanks to Clemens Fischer for spotting that.
657
658 Add IPv6 support to the TFTP server. Many thanks to Jan
659 'RedBully' Seiffert for the patches.
660
661 Log DNS queries at level LOG_INFO, rather then
662 LOG_DEBUG. This makes things consistent with DHCP
663 logging. Thanks to Adam Pribyl for spotting the problem.
664
665 Ensure that dnsmasq terminates cleanly when using
666 --syslog-async even if it cannot make a connection to the
667 syslogd.
668
669 Add --add-mac option. This is to support currently
670 experimental DNS filtering facilities. Thanks to Benjamin
671 Petrin for the orignal patch.
672
673 Fix bug which meant that tags were ignored in dhcp-range
674 configuration specifying PXE-proxy service. Thanks to
675 Cristiano Cumer for spotting this.
676
677 Raise an error if there is extra junk, not part of an
678 option, on the command line.
679
680 Flag a couple of log messages in cache.c as coming from
681 the DHCP subsystem. Thanks to Olaf Westrik for the patch.
682
683 Omit timestamps from logs when a) logging to stderr and
684 b) --keep-in-forground is set. The logging facility on the
685 other end of stderr can be assumned to supply them. Thanks
686 to John Hallam for the patch.
687
688 Don't complain about strings longer than 255 characters in
689 --txt-record, just split the long strings into 255
690 character chunks instead.
691
692 Fix crash on double-free. This bug can only happen when
693 dhcp-script is in use and then only in rare circumstances
694 triggered by high DHCP transaction rate and a slow
695 script. Thanks to Ferenc Wagner for finding the problem.
696
697 Only log that a file has been sent by TFTP after the
698 transfer has completed succesfully.
699
700 A good suggestion from Ferenc Wagner: extend
701 the --domain option to allow this sort of thing:
702 --domain=thekelleys.org.uk,192.168.0.0/24,local
703 which automatically creates
704 --local=/thekelleys.org.uk/
705 --local=/0.168.192.in-addr.arpa/
706
707 Tighten up syntax checking of hex contants in the config
708 file. Thanks to Fred Damen for spotting this.
709
710 Add dnsmasq logo/icon, contributed by Justin Swift. Many
711 thanks for that.
712
713 Never cache DNS replies which have the 'cd' bit set, or
714 which result from queries forwarded with the 'cd' bit
715 set. The 'cd' bit instructs a DNSSEC validating server
716 upstream to ignore signature failures and return replies
717 anyway. Without this change it's possible to pollute the
718 dnsmasq cache with bad data by making a query with the
719 'cd' bit set and subsequent queries would return this data
720 without its being marked as suspect. Thanks to Anders
721 Kaseorg for pointing out this problem.
722
723 Add --proxy-dnssec flag, for compliance with RFC
724 4035. Dnsmasq will now clear the 'ad' bit in answers returned
725 from upstream validating nameservers unless this option is
726 set.
727
728 Allow a filename of "-" for --conf-file to read
729 stdin. Suggestion from Timothy Redaelli.
730
731 Rotate the order of SRV records in replies, to provide
732 round-robin load balancing when all the priorities are
733 equal. Thanks to Peter McKinney for the suggestion.
734
735 Edit
736 contrib/MacOSX-launchd/uk.org.thekelleys.dnsmasq.plist
737 so that it doesn't log all queries to a file by
738 default. Thanks again to Peter McKinney.
739
740 By default, setting an IPv4 address for a domain but not
741 an IPv6 address causes dnsmasq to return
742 an NODATA reply for IPv6 (or vice-versa). So
743 --address=/google.com/1.2.3.4 stops IPv6 queries for
744 *google.com from being forwarded. Make it possible to
745 override this behaviour by defining the sematics if the
746 same domain appears in both --server and --address.
747 In that case, the --address has priority for the address
748 family in which is appears, but the --server has priority
749 of the address family which doesn't appear in --adddress
750 So:
751 --address=/google.com/1.2.3.4
752 --server=/google.com/#
753 will return 1.2.3.4 for IPv4 queries for *.google.com but
754 forward IPv6 queries to the normal upstream nameserver.
755 Similarly when setting an IPv6 address
756 only this will allow forwarding of IPv4 queries. Thanks to
757 William for pointing out the need for this.
758
759 Allow more than one --dhcp-optsfile and --dhcp-hostsfile
760 and make them understand directories as arguments in the
761 same way as --addn-hosts. Suggestion from John Hanks.
762
763 Ignore rebinding requests for leases we don't know
764 about. Rebind is broadcast, so we might get to overhear a
765 request meant for another DHCP server. NAKing this is
766 wrong. Thanks to Brad D'Hondt for assistance with this.
767

Simon Kelley8ef5ada2010-06-03 19:42:45 +0100789version 2.53
790 Fix failure to compile on Debian/kFreeBSD. Thanks to
791 Axel Beckert and Petr Salinger.
792
793 Fix code to avoid scary strict-aliasing warnings
794 generated by gcc 4.4.
795
796 Added FAQ entry warning about DHCP failures with Vista
797 when firewalls block 255.255.255.255.
798
799 Fixed bug which caused bad things to happen if a
800 resolv.conf file which exists is subsequently removed.
801 Thanks to Nikolai Saoukh for the patch.
802
803 Rationalised the DHCP tag system. Every configuration item
804 which can set a tag does so by adding "set:<tag>" and
805 every configuration item which is conditional on a tag is
806 made so by "tag:<tag>". The NOT operator changes to '!',
807 which is a bit more intuitive too. Dhcp-host directives
808 can set more than one tag now. The old '#' NOT,
809 "net:" prefix and no-prefixes are still honoured, so
810 no existing config file needs to be changed, but
811 the documentation and new-style config files should be
812 much less confusing.
813
814 Added --tag-if to allow boolean operations on tags.
815 This allows complicated logic to be clearer and more
816 general. A great suggestion from Richard Voigt.
817
818 Add broadcast/unicast information to DHCP logging.
819
820 Allow --dhcp-broadcast to be unconditional.
821
822 Fixed incorrect behaviour with NOT <tag> conditionals in
823 dhcp-options. Thanks to Max Turkewitz for assistance
824 finding this.
825
826 If we send vendor-class encapsulated options based on the
827 vendor-class supplied by the client, and no explicit
828 vendor-class option is given, echo back the vendor-class
829 from the client.
830
831 Fix bug which stopped dnsmasq from matching both a
832 circuitid and a remoteid. Thanks to Ignacio Bravo for
833 finding this.
834
835 Add --dhcp-proxy, which makes it possible to configure
836 dnsmasq to use a DHCP relay agent as a full proxy, with
837 all DHCP messages passing through the proxy. This is
838 useful if the relay adds extra information to the packets
839 it forwards, but cannot be configured with the RFC 5107
840 server-override option.
841
842 Added interface:<iface name> part to dhcp-range. The
843 semantics of this are very odd at first sight, but it
844 allows a single line of the form
845 dhcp-range=interface:virt0,192.168.0.4,192.168.0.200
846 to be added to dnsmasq configuration which then supplies
847 DHCP and DNS services to that interface, without affecting
848 what services are supplied to other interfaces and
849 irrespective of the existance or lack of
850 interface=<interface>
851 lines elsewhere in the dnsmasq configuration. The idea is
852 that such a line can be added automatically by libvirt
853 or equivalent systems, without disturbing any manual
854 configuration.
855
856 Similarly to the above, allow --enable-tftp=<interface>
857
858 Allow a TFTP root to be set separately for requests via
859 different interfaces, --tftp-root=<path>,<interface>
860
861 Correctly handle and log clashes between CNAMES and
862 DNS names being given to DHCP leases. This fixes a bug
863 which caused nonsense IP addresses to be logged. Thanks to
864 Sergei Zhirikov for finding and analysing the problem.
865
866 Tweak flush_log so as to avoid leaving the log
867 file in non-blocking mode. O_NONBLOCK is a property of the
868 file, not the process/descriptor.
869
870 Fix contrib/Solaris10/create_package
871 (/usr/man -> /usr/share/man) Thanks to Vita Batrla.
872
873 Fix a problem where, if a client got a lease, then went
874 to another subnet and got another lease, then moved back,
875 it couldn't resume the old lease, but would instead get
876 a new address. Thanks to Leonardo Rodrigues for spotting
877 this and testing the fix.
878
879 Fix weird bug which sometimes omitted certain characters
880 from the start of quoted strings in dhcp-options. Thanks
881 to Dayton Turner for spotting the problem.
882
883 Add facility to redirect some domains to the standard
884 upstream servers: this allows something like
885 --server=/google.com/1.2.3.4 --server=/www.google.com/#
886 which will send queries for *.google.com to 1.2.3.4,
887 except *www.google.com which will be forwarded as usual.
888 Thanks to AJ Weber for prompting this addition.
889
890 Improve the hash-algorithm used to generate IP addresses
891 from MAC addresses during initial DHCP address
892 allocation. This improves performance when large numbers
893 of hosts with similar MAC addresses all try and get an IP
894 address at the same time. Thanks to Paul Smith for his
895 work on this.
896
897 Tweak DHCP code so that --bridge-interface can be used to
898 select which IP alias of an interface should be used for
899 DHCP purposes on Linux. If eth0 has an alias eth0:dhcp
900 then adding --bridge-interface=eth0:dhcp,eth0 will use
901 the address of eth0:dhcp to determine the correct subnet
902 for DHCP address allocation. Thanks to Pawel Golaszewski
903 for prompting this and Eric Cooper for further testing.
904
905 Add --dhcp-generate-names. Suggestion by Ferenc Wagner.
906
907 Tweak DNS server selection algorithm when there is more
908 than one server available for a domain, eg.
909 --server=/mydomain/1.1.1.1
910 --server=/mydomain/2.2.2.2
911 Thanks to Alberto Cuesta-Canada for spotting a weakness
912 here.
913
914 Add --max-ttl. Thanks to Fredrik Ringertz for the patch.
915
916 Allow --log-facility=- to force all logging to
917 stderr. Suggestion from Clemens Fischer.
918
919 Fix regression which caused configuration like
920 --address=/.domain.com/1.2.3.4 to be rejected. The dot to the
921 left of the domain has been implied and not required for a
922 long time, but it should be accepted for backward
923 compatibility. Thanks to Andrew Burcin for spotting this.
924
925 Add --rebind-domain-ok and --rebind-localhost-ok.
926 Suggestion from Clemens Fischer.
927
928 Log replies to queries of type TXT, when --log-queries
929 is set.
930
931 Fix compiler warnings when compiled with -DNO_DHCP. Thanks
932 to Shantanu Gadgil for the patch.
933
934 Updated French translation. Thanks to Gildas Le Nadan.
935
936 Updated Polish translation. Thanks to Jan Psota.
937
938 Updated German translation. Thanks to Matthias Andree.
939
940 Added contrib/static-arp, thanks to Darren Hoo.
941
942 Fix corruption of the domain when a name from /etc/hosts
943 overrides one supplied by a DHCP client. Thanks to Fedor
944 Kozhevnikov for spotting the problem.
945
946 Updated Spanish translation. Thanks to Chris Chatham.
947
948
Simon Kelley316e2732010-01-22 20:16:09 +0000949version 2.52
950 Work around a Linux kernel bug which insists that the
951 length of the option passed to setsockopt must be at least
952 sizeof(int) bytes, even if we're calling SO_BINDTODEVICE
953 and the device name is "lo". Note that this is fixed
954 in kernel 2.6.31, but the workaround is harmless and
955 allows earlier kernels to be used. Also fix dnsmasq
956 bug which reported the wrong address when this failed.
957 Thanks to Fedor for finding this.
958
959 The API for IPv6 PKTINFO changed around Linux kernel
960 2.6.14. Workaround the case where dnsmasq is compiled
961 against newer headers, but then run on an old kernel:
962 necessary for some *WRT distros.
963
964 Re-read the set of network interfaces when re-loading
965 /etc/resolv.conf if --bind-interfaces is not set. This
966 handles the case that loopback interfaces do not exist
967 when dnsmasq is first started.
968
969 Tweak the PXE code to support port 4011. This should
970 reduce broadcasts and make things more reliable when other
971 servers are around. It also improves inter-operability
972 with certain clients.
973
974 Make a pxe-service configuration with no filename or boot
975 service type legal: this does a local boot. eg.
976 pxe-service=x86PC, "Local boot"
977
978 Be more conservative in detecting "A for A"
979 queries. Dnsmasq checks if the name in a type=A query looks
980 like a dotted-quad IP address and answers the query itself
981 if so, rather than forwarding it. Previously dnsmasq
982 relied in the library function inet_addr() to convert
983 addresses, and that will accept some things which are
984 confusing in this context, like 1.2.3 or even just
985 1234. Now we only do A for A processing for four decimal
986 numbers delimited by dots.
987
988 A couple of tweaks to fix compilation on Solaris. Thanks
989 to Joel Macklow for help with this.
990
991 Another Solaris compilation tweak, needed for Solaris
992 2009.06. Thanks to Lee Essen for that.
993
994 Added extract packaging stuff from Lee Essen to
995 contrib/Solaris10.
996
997 Increased the default limit on number of leases to 1000
998 (from 150). This is mainly a defence against DoS attacks,
999 and for the average "one for two class C networks"
1000 installation, IP address exhaustion does that just as
1001 well. Making the limit greater than the number of IP
1002 addresses available in such an installation removes a
1003 surprise which otherwise can catch people out.
1004
1005 Removed extraneous trailing space in the value of the
1006 DNSMASQ_TIME_REMAINING DNSMASQ_LEASE_LENGTH and
1007 DNSMASQ_LEASE_EXPIRES environment variables. Thanks to
1008 Gildas Le Nadan for spotting this.
1009
1010 Provide the network-id tags for a DHCP transaction to
1011 the lease-change script in the environment variable
1012 DNSMASQ_TAGS. A good suggestion from Gildas Le Nadan.
1013
1014 Add support for RFC3925 "Vendor-Identifying Vendor
1015 Options". The syntax looks like this:
1016 --dhcp-option=vi-encap:<enterprise number>, .........
1017
1018 Add support to --dhcp-match to allow matching against
1019 RFC3925 "Vendor-Identifying Vendor Classes". The syntax
1020 looks like this:
1021 --dhcp-match=tag,vi-encap<enterprise number>, <value>
1022
1023 Add some application specific code to assist in
1024 implementing the Broadband forum TR069 CPE-WAN
1025 specification. The details are in contrib/CPE-WAN/README
1026
1027 Increase the default DNS packet size limit to 4096, as
1028 recommended by RFC5625 section 4.4.3. This can be
1029 reconfigured using --edns-packet-max if needed. Thanks to
1030 Francis Dupont for pointing this out.
1031
Simon Kelley8ef5ada2010-06-03 19:42:45 +01001032 Rewrite query-ids even for TSIG signed packets, since
Simon Kelley316e2732010-01-22 20:16:09 +00001033 this is allowed by RFC5625 section 4.5.
1034
1035 Use getopt_long by default on OS X. It has been supported
1036 since version 10.3.0. Thanks to Arek Dreyer for spotting
1037 this.
1038
1039 Added up-to-date startup configuration for MacOSX/launchd
1040 in contrib/MacOSX-launchd. Thanks to Arek Dreyer for
1041 providing this.
1042
1043 Fix link error when including Dbus but excluding DHCP.
1044 Thanks to Oschtan for the bug report.
1045
1046 Updated French translation. Thanks to Gildas Le Nadan.
1047
1048 Updated Polish translation. Thanks to Jan Psota.
1049
1050 Updated Spanish translation. Thanks to Chris Chatham.
1051
Simon Kelley8ef5ada2010-06-03 19:42:45 +01001052 Fixed confusion about domains, when looking up DHCP hosts
1053 in /etc/hosts. This could cause spurious "Ignoring
1054 domain..." messages. Thanks to Fedor Kozhevnikov for
1055 finding and analysing the problem.
Simon Kelley316e2732010-01-22 20:16:09 +00001056
Simon Kelley8ef5ada2010-06-03 19:42:45 +01001057
Simon Kelley1f15b812009-10-13 17:49:32 +01001058version 2.51
1059 Add support for internationalised DNS. Non-ASCII characters
1060 in domain names found in /etc/hosts, /etc/ethers and
1061 /etc/dnsmasq.conf will be correctly handled by translation to
1062 punycode, as specified in RFC3490. This function is only
1063 available if dnsmasq is compiled with internationalisation
1064 support, and adds a dependency on GNU libidn. Without i18n
1065 support, dnsmasq continues to be compilable with just
1066 standard tools. Thanks to Yves Dorfsman for the
1067 suggestion.
1068
1069 Add two more environment variables for lease-change scripts:
1070 First, DNSMASQ_SUPPLIED_HOSTNAME; this is set to the hostname
1071 supplied by a client, even if the actual hostname used is
1072 over-ridden by dhcp-host or dhcp-ignore-names directives.
1073 Also DNSMASQ_RELAY_ADDRESS which gives the address of
1074 a DHCP relay, if used.
1075 Suggestions from Michael Rack.
1076
1077 Fix regression which broke echo of relay-agent
1078 options. Thanks to Michael Rack for spotting this.
1079
1080 Don't treat option 67 as being interchangeable with
1081 dhcp-boot parameters if it's specified as
1082 dhcp-option-force.
1083
1084 Make the code to call scripts on lease-change compile-time
1085 optional. It can be switched off by editing src/config.h
1086 or building with "make COPTS=-DNO_SCRIPT".
1087
1088 Make the TFTP server cope with filenames from Windows/DOS
1089 which use '\' as pathname separator. Thanks to Ralf for
1090 the patch.
1091
1092 Updated Polish translation. Thanks to Jan Psota.
1093
1094 Warn if an IP address is duplicated in /etc/ethers. Thanks
1095 to Felix Schwarz for pointing this out.
1096
1097 Teach --conf-dir to take an option list of file suffices
1098 which will be ignored when scanning the directory. Useful
1099 for backup files etc. Thanks to Helmut Hullen for the
1100 suggestion.
1101
1102 Add new DHCP option named tftpserver-address, which
1103 corresponds to the third argument of dhcp-boot. This
1104 allows the complete functionality of dhcp-boot to be
1105 replicated with dhcp-option. Useful when using
1106 dhcp-optsfile.
1107
1108 Test which upstream nameserver to use every 10 seconds
1109 or 50 queries and not just when a query times out and
1110 is retried. This should improve performance when there
1111 is a slow nameserver in the list. Thanks to Joe for the
1112 suggestion.
1113
1114 Don't do any PXE processing, even for clients with the
1115 correct vendorclass, unless at least one pxe-prompt or
1116 pxe-service option is given. This stops dnsmasq
1117 interfering with proxy PXE subsystems when it is just
1118 the DHCP server. Thanks to Spencer Clark for spotting this.
1119
1120 Limit the blocksize used for TFTP transfers to a value
1121 which avoids packet fragmentation, based on the MTU of the
1122 local interface. Many netboot ROMs can't cope with
1123 fragmented packets.
1124
1125 Honour dhcp-ignore configuration for PXE and proxy-PXE
1126 requests. Thanks to Niels Basjes for the bug report.
1127
1128 Updated French translation. Thanks to Gildas Le Nadan.

Simon Kelley1f15b812009-10-13 17:49:32 +01001132 Fix security problem which allowed any host permitted to
Simon Kelley77e94da2009-08-31 17:32:17 +01001133 do TFTP to possibly compromise dnsmasq by remote buffer
1134 overflow when TFTP enabled. Thanks to Core Security
1135 Technologies and Iván Arce, Pablo Hernán Jorge, Alejandro
1136 Pablo Rodriguez, Martín Coco, Alberto Soliño Testa and
1137 Pablo Annetta. This problem has Bugtraq id: 36121
1138 and CVE: 2009-2957
1139
1140 Fix a problem which allowed a malicious TFTP client to
1141 crash dnsmasq. Thanks to Steve Grubb at Red Hat for
1142 spotting this. This problem has Bugtraq id: 36120 and
1143 CVE: 2009-2958

Simon Kelley03a97b62009-06-10 20:55:49 +01001146version 2.49
1147 Fix regression in 2.48 which disables the lease-change
1148 script. Thanks to Jose Luis Duran for spotting this.
1149
1150 Log TFTP "file not found" errors. These were not logged,
1151 since a normal PXELinux boot generates many of them, but
1152 the lack of the messages seems to be more confusing than
1153 routinely seeing them when there is no real error.
1154
1155 Update Spanish translation. Thanks to Chris Chatham.

1157
Simon Kelley7622fc02009-06-04 20:32:05 +01001158version 2.48
1159 Archived the extensive, backwards, changelog to
1160 CHANGELOG.archive. The current changelog now runs from
1161 version 2.43 and runs conventionally.
Simon Kelley9e4abcb2004-01-22 19:47:41 +00001162
Simon Kelley7622fc02009-06-04 20:32:05 +01001163 Fixed bug which broke binding of servers to physical
1164 interfaces when interface names were longer than four
1165 characters. Thanks to MURASE Katsunori for the patch.
Simon Kelley9e4abcb2004-01-22 19:47:41 +00001166
Simon Kelley7622fc02009-06-04 20:32:05 +01001167 Fixed netlink code to check that messages come from the
1168 correct source, and not another userspace process. Thanks
1169 to Steve Grubb for the patch.
Simon Kelley9e4abcb2004-01-22 19:47:41 +00001170
Simon Kelley7622fc02009-06-04 20:32:05 +01001171 Maintainability drive: removed bug and missing feature
1172 workarounds for some old platforms. Solaris 9, OpenBSD
1173 older than 4.1, Glibc older than 2.2, Linux 2.2.x and
1174 DBus older than 1.1.x are no longer supported.
Simon Kelley9e4abcb2004-01-22 19:47:41 +00001175
Simon Kelley7622fc02009-06-04 20:32:05 +01001176 Don't read included configuration files more than once:
1177 allows complex configuration structures without problems.
Simon Kelley9e4abcb2004-01-22 19:47:41 +00001178
Simon Kelley7622fc02009-06-04 20:32:05 +01001179 Mark log messages from the various subsystems in dnsmasq:
1180 messages from the DHCP subsystem now have the ident string
1181 "dnsmasq-dhcp" and messages from TFTP have ident
1182 "dnsmasq-tftp". Thanks to Olaf Westrik for the patch.
Simon Kelley9e4abcb2004-01-22 19:47:41 +00001183
Simon Kelley7622fc02009-06-04 20:32:05 +01001184 Fix possible infinite DHCP protocol loop when an IP
1185 address nailed to a hostname (not a MAC address) and a
1186 host sometimes provides the name, sometimes not.
Simon Kelley9e4abcb2004-01-22 19:47:41 +00001187
Simon Kelley7622fc02009-06-04 20:32:05 +01001188 Allow --addn-hosts to take a directory: all the files
1189 in the directory are read. Thanks to Phil Cornelius for
1190 the suggestion.
Simon Kelley9e4abcb2004-01-22 19:47:41 +00001191
Simon Kelley7622fc02009-06-04 20:32:05 +01001192 Support --bridge-interface on all platforms, not just BSD.
Simon Kelley1ab84e22004-01-29 16:48:35 +00001193
Simon Kelley7622fc02009-06-04 20:32:05 +01001194 Added support for advanced PXE functions. It's now
1195 possible to define a prompt and menu options which will
1196 be displayed when a client PXE boots. It's also possible to
1197 hand-off booting to other boot servers. Proxy-DHCP, where
1198 dnsmasq just supplies the PXE information and another DHCP
1199 server does address allocation, is also allowed. See the
1200 --pxe-prompt and --pxe-service keywords. Thanks to
1201 Alkis Georgopoulos for the suggestion and Guilherme Moro
1202 and Michael Brown for assistance.
Simon Kelley1ab84e22004-01-29 16:48:35 +00001203
Simon Kelley7622fc02009-06-04 20:32:05 +01001204 Improvements to DHCP logging. Thanks to Tom Metro for
1205 useful suggestions.
1206
1207 Add ability to build dnsmasq without DHCP support. To do
1208 this, edit src/config.h or build with
1209 "make COPTS=-DNO_DHCP". Thanks to Mahavir Jain for the patch.
1210
1211 Added --test command-line switch - syntax check
1212 configuration files only.
Simon Kelley33820b72004-04-03 21:10:00 +01001213

1217version 2.47
1218 Updated French translation. Thanks to Gildas Le Nadan.
1219
1220 Fixed interface enumeration code to work on NetBSD
1221 5.0. Thanks to Roy Marples for the patch.
1222
1223 Updated config.h to use the same location for the lease
1224 file on NetBSD as the other *BSD variants. Also allow
1225 LEASEFILE and CONFFILE symbols to be overriden in CFLAGS.
1226
1227 Handle duplicate address detection on IPv6 more
1228 intelligently. In IPv6, an interface can have an address
1229 which is not usable, because it is still undergoing DAD
1230 (such addresses are marked "tentative"). Attempting to
1231 bind to an address in this state returns an error,
1232 EADDRNOTAVAIL. Previously, on getting such an error,
1233 dnsmasq would silently abandon the address, and never
1234 listen on it. Now, it retries once per second for 20
1235 seconds before generating a fatal error. 20 seconds should
1236 be long enough for any DAD process to complete, but can be
1237 adjusted in src/config.h if necessary. Thanks to Martin
1238 Krafft for the bug report.

1240 Add DBus introspection. Patch from Jeremy Laine.
1241
1242 Update Dbus configuration file. Patch from Colin Walters.
1243 Fix for this bug:
1244 http://bugs.freedesktop.org/show_bug.cgi?id=18961
1245
1246 Support arbitrarily encapsulated DHCP options, suggestion
1247 and initial patch from Samium Gromoff. This is useful for
1248 (eg) gPXE, which expect all its private options to be
1249 encapsulated inside a single option 175. So, eg,
1250
1251 dhcp-option = encap:175, 190, "iscsi-client0"
1252 dhcp-option = encap:175, 191, "iscsi-client0-secret"
1253
1254 will provide iSCSI parameters to gPXE.
1255
1256 Enhance --dhcp-match to allow testing of the contents of a
1257 client-sent option, as well as its presence. This
1258 application in mind for this is RFC 4578
1259 client-architecture specifiers, but it's generally useful.
1260 Joey Korkames suggested the enhancement.
1261
1262 Move from using the IP_XMIT_IF ioctl to IP_BOUND_IF on
1263 OpenSolaris. Thanks to Bastian Machek for the heads-up.
1264
1265 No longer complain about blank lines in
1266 /etc/ethers. Thanks to Jon Nelson for the patch.
1267
1268 Fix binding of servers to physical devices, eg
1269 --server=/domain/1.2.3.4@eth0 which was broken from 2.43
1270 onwards unless --query-port=0 set. Thanks to Peter Naulls
1271 for the bug report.
1272
1273 Reply to DHCPINFORM requests even when the supplied ciaddr
1274 doesn't fall in any dhcp-range. In this case it's not
1275 possible to supply a complete configuration, but
1276 individually-configured options (eg PAC) may be useful.
1277
1278 Allow the source address of an alias to be a range:
1279 --alias=192.168.0.0,10.0.0.0,255.255.255.0 maps the whole
1280 subnet 192.168.0.0->192.168.0.255 to 10.0.0.0->10.0.0.255,
1281 as before.
1282 --alias=192.168.0.10-192.168.0.40,10.0.0.0,255.255.255.0
1283 maps only the 192.168.0.10->192.168.0.40 region. Thanks to
1284 Ib Uhrskov for the suggestion.
1285
1286 Don't dynamically allocate DHCP addresses which may break
1287 Windows. Addresses which end in .255 or .0 are broken in
1288 Windows even when using supernetting.
1289 --dhcp-range=192.168.0.1,192.168.1.254,255,255,254.0 means
1290 192.168.0.255 is a valid IP address, but not for Windows.
1291 See Microsoft KB281579. We therefore no longer allocate
1292 these addresses to avoid hard-to-diagnose problems.
1293
1294 Update Polish translation. Thanks to Jan Psota.
1295
1296 Delete the PID-file when dnsmasq shuts down. Note that by
1297 this time, dnsmasq is normally not running as root, so
1298 this will fail if the PID-file is stored in a root-owned
1299 directory; such failure is silently ignored. To take
1300 advantage of this feature, the PID-file must be stored in a
1301 directory owned and write-able by the user running
1302 dnsmasq.

1306 Allow --bootp-dynamic to take a netid tag, so that it may
1307 be selectively enabled. Thanks to Olaf Westrik for the
1308 suggestion.
1309
1310 Remove ISC-leasefile reading code. This has been
1311 deprecated for a long time, and last time I removed it, it
1312 ended up going back by request of one user. This time,
1313 it's gone for good; otherwise it would need to be
1314 re-worked to support multiple domains (see below).
1315
1316 Support DHCP clients in multiple DNS domains. This is a
1317 long-standing request. Clients are assigned to a domain
1318 based in their IP address.
1319
1320 Add --dhcp-fqdn flag, which changes behaviour if DNS names
1321 assigned to DHCP clients. When this is set, there must be
1322 a domain associated with each client, and only
1323 fully-qualified domain names are added to the DNS. The
1324 advantage is that the only the FQDN needs to be unique,
1325 so that two or more DHCP clients can share a hostname, as
1326 long as they are in different domains.
1327
1328 Set environment variable DNSMASQ_DOMAIN when invoking
1329 lease-change script. This may be useful information to
1330 have now that it's variable.
1331
1332 Tighten up data-checking code for DNS packet
1333 handling. Thanks to Steve Dodd who found certain illegal
1334 packets which could crash dnsmasq. No memory overwrite was
1335 possible, so this is not a security issue beyond the DoS
1336 potential.
1337
1338 Update example config dhcp option 47, the previous
1339 suggestion generated an illegal, zero-length,
1340 option. Thanks to Matthias Andree for finding this.
1341
1342 Rewrite hosts-file reading code to remove the limit of
1343 1024 characters per line. John C Meuser found this.
1344
1345 Create a net-id tag with the name of the interface on
1346 which the DHCP request was received.
1347
1348 Fixed minor memory leak in DBus code, thanks to Jeremy
1349 Laine for the patch.
1350
1351 Emit DBus signals as the DHCP lease database
1352 changes. Thanks to Jeremy Laine for the patch.
1353
1354 Allow for more that one MAC address in a dhcp-host
1355 line. This configuration tells dnsmasq that it's OK to
1356 abandon a DHCP lease of the fixed address to one MAC
1357 address, if another MAC address in the dhcp-host statement
1358 asks for an address. This is useful to give a fixed
1359 address to a host which has two network interfaces
1360 (say, a laptop with wired and wireless interfaces.)
1361 It's very important to ensure that only one interface
1362 at a time is up, since dnsmasq abandons the first lease
1363 and re-uses the address before the leased time has
1364 elapsed. John Gray suggested this.
1365
1366 Tweak the response to a DHCP request packet with a wrong
1367 server-id when --dhcp-authoritative is set; dnsmasq now
1368 returns a DHCPNAK, rather than silently ignoring the
1369 packet. Thanks to Chris Marget for spotting this
1370 improvement.
1371
1372 Add --cname option. This provides a limited alias
1373 function, usable for DHCP names. Thanks to AJ Weber for
1374 suggestions on this.
1375
1376 Updated contrib/webmin with latest version from Neil
1377 Fisher.
1378
1379 Updated Polish translation. Thanks to Jan Psota.
1380
1381 Correct the text names for DHCP options 64 and 65 to be
1382 "nis+-domain" and "nis+-servers".
1383
1384 Updated Spanish translation. Thanks to Chris Chatham.
1385
1386 Force re-reading of /etc/resolv.conf when an "interface
1387 up" event occurs.
1388
1389
1390version 2.45
1391 Fix total DNS failure in release 2.44 unless --min-port
1392 specified. Thanks to Steven Barth and Grant Coady for
1393 bugreport. Also reject out-of-range port spec, which could
1394 break things too: suggestion from Gilles Espinasse.
1395
1396
1397version 2.44
1398 Fix crash when unknown client attempts to renew a DHCP
1399 lease, problem introduced in version 2.43. Thanks to
1400 Carlos Carvalho for help chasing this down.
1401
1402 Fix potential crash when a host which doesn't have a lease
1403 does DHCPINFORM. Again introduced in 2.43. This bug has
1404 never been reported in the wild.
1405
1406 Fix crash in netlink code introduced in 2.43. Thanks to
1407 Jean Wolter for finding this.
1408
1409 Change implementation of min_port to work even if min-port
1410 is large.
1411
1412 Patch to enable compilation of latest Mac OS X. Thanks to
1413 David Gilman.
1414
1415 Update Spanish translation. Thanks to Christopher Chatham.

1421 Flag errors when configuration options are repeated
1422 illegally.
1423
1424 Further tweaks for GNU/kFreeBSD
1425
1426 Add --no-wrap to msgmerge call - provides nicer .po file
1427 format.
1428
1429 Honour lease-time spec in dhcp-host lines even for
1430 BOOTP. The user is assumed to known what they are doing in
1431 this case. (Hosts without the time spec still get infinite
1432 leases for BOOTP, over-riding the default in the
1433 dhcp-range.) Thanks to Peter Katzmann for uncovering this.
1434
1435 Fix problem matching relay-agent ids. Thanks to Michael
1436 Rack for the bug report.
1437
1438 Add --naptr-record option. Suggestion from Johan
1439 Bergquist.
1440
1441 Implement RFC 5107 server-id-override DHCP relay agent
1442 option.
1443
1444 Apply patches from Stefan Kruger for compilation on
1445 Solaris 10 under Sun studio.
1446
1447 Yet more tweaking of Linux capability code, to suppress
1448 pointless wingeing from kernel 2.6.25 and above.
1449
1450 Improve error checking during startup. Previously, some
1451 errors which occurred during startup would be worked
1452 around, with dnsmasq still starting up. Some were logged,
1453 some silent. Now, they all cause a fatal error and dnsmasq
1454 terminates with a non-zero exit code. The errors are those
1455 associated with changing uid and gid, setting process
1456 capabilities and writing the pidfile. Thanks to Uwe
1457 Gansert and the Suse security team for pointing out
1458 this improvement, and Bill Reimers for good implementation
1459 suggestions.
1460
1461 Provide NO_LARGEFILE compile option to switch off largefile
1462 support when compiling against versions of uclibc which
1463 don't support it. Thanks to Stephane Billiart for the patch.
1464
1465 Implement random source ports for interactions with
1466 upstream nameservers. New spoofing attacks have been found
1467 against nameservers which do not do this, though it is not
1468 clear if dnsmasq is vulnerable, since to doesn't implement
1469 recursion. By default dnsmasq will now use a different
1470 source port (and socket) for each query it sends
1471 upstream. This behaviour can suppressed using the
1472 --query-port option, and the old default behaviour
1473 restored using --query-port=0. Explicit source-port
1474 specifications in --server configs are still honoured.
1475
1476 Replace the random number generator, for better
1477 security. On most BSD systems, dnsmasq uses the
1478 arc4random() RNG, which is secure, but on other platforms,
1479 it relied on the C-library RNG, which may be
1480 guessable and therefore allow spoofing. This release
1481 replaces the libc RNG with the SURF RNG, from Daniel
1482 J. Berstein's DJBDNS package.
1483
1484 Don't attempt to change user or group or set capabilities
1485 if dnsmasq is run as a non-root user. Without this, the
1486 change from soft to hard errors when these fail causes
1487 problems for non-root daemons listening on high
1488 ports. Thanks to Patrick McLean for spotting this.
1489
1490 Updated French translation. Thanks to Gildas Le Nadan.
