6 | Remove floor of 4096 on advertised EDNS0 packet size when | |
7 | DNSSEC in use, the original rationale for this has long gone. | |

10 | Use inotify for checking on updates to /etc/resolv.conf and |
11 | friends under Linux. This fixes race conditions when the files are | |

12 | updated rapidly and saves CPU by noy polling. To build |
13 | a binary that runs on old Linux kernels without inotify, | |
14 | use make COPTS=-DNO_INOTIFY | |

16 | Fix breakage of --domain=<domain>,<subnet>,local - only reverse | |
17 | queries were intercepted. THis appears to have been broken | |
18 | since 2.69. Thanks to Josh Stone for finding the bug. | |

20 | Eliminate IPv6 privacy addresses and deprecated addresses from | |
21 | the answers given by --interface-name. Note that reverse queries | |
22 | (ie looking for names, given addresses) are not affected. | |
23 | Thanks to Michael Gorbach for the suggestion. | |

28 | Add --ignore-address option. Ignore replies to A-record | |
29 | queries which include the specified address. No error is | |
30 | generated, dnsmasq simply continues to listen for another | |
31 | reply. This is useful to defeat blocking strategies which | |
32 | rely on quickly supplying a forged answer to a DNS | |
33 | request for certain domains, before the correct answer can | |
34 | arrive. Thanks to Glen Huang for the patch. | |

36 | Revisit the part of DNSSEC validation which determines if an |
37 | unsigned answer is legit, or is in some part of the DNS | |
38 | tree which should be signed. Dnsmasq now works from the | |
39 | DNS root downward looking for the limit of signed | |
40 | delegations, rather than working bottom up. This is | |
41 | both more correct, and less likely to trip over broken | |
42 | nameservers in the unsigned parts of the DNS tree | |
43 | which don't respond well to DNSSEC queries. | |

48 | Add --min-cache-ttl option. I've resisted this for a long |
49 | time, on the grounds that disbelieving TTLs is never a | |
50 | good idea, but I've been persuaded that there are | |
51 | sometimes reasons to do it. (Step forward, GFW). | |
52 | To avoid misuse, there's a hard limit on the TTL | |
53 | floor of one hour. Thansk to RinSatsuki for the patch. | |

58 | |
59 | Add --dhcp-hostsdir. This allows addition of new host | |
60 | configurations to a running dnsmasq instance much more | |
61 | cheaply than having dnsmasq re-read all its existing | |
62 | configuration each time. | |

70 | Add --dnssec-timestamp option, which provides an automatic | |
38440b20 SK |
71 | way to detect when the system time becomes valid after |
72 | boot on systems without an RTC, whilst allowing DNS | |
73 | queries before the clock is valid so that NTP can run. | |

79 | Fix crash caused by looking up servers.bind, CHAOS text |
80 | record, when more than about five --servers= lines are | |
81 | in the dnsmasq config. This causes memory corruption | |
82 | which causes a crash later. Thanks to Matt Coddington for | |
83 | sterling work chasing this down. | |

87 | Note that this is could allow the dnsmasq process's |
88 | memory to be read by an attacker under certain | |

91 | Fix crash in authoritative DNS code, if a .arpa zone | |
92 | is declared as authoritative, and then a PTR query which | |
93 | is not to be treated as authoritative arrived. Normally, | |
94 | directly declaring .arpa zone as authoritative is not | |
95 | done, so this crash wouldn't be seen. Instead the | |
96 | relevant .arpa zone should be specified as a subnet | |
97 | in the auth-zone declaration. Thanks to Johnny S. Lee | |
98 | for the bugreport and initial patch. | |

100 | Fix authoritative DNS code to correctly reply to NS |
101 | and SOA queries for .arpa zones for which we are | |
102 | declared authoritative by means of a subnet in auth-zone. | |
103 | Previously we provided correct answers to PTR queries | |
104 | in such zones (including NS and SOA) but not direct | |
105 | NS and SOA queries. Thanks to Johnny S. Lee for | |

112 | Try and handle net connections with broken fragmentation |
113 | that lose large UDP packets. If a server times out, | |

149 | When assigning existing DHCP leases to intefaces by comparing |
150 | networks, handle the case that two or more interfaces have the | |

b5ea1cc2 SK |
155 | Add a mode which detects and removes DNS forwarding loops, ie |
156 | a query sent to an upstream server returns as a new query to | |
157 | dnsmasq, and would therefore be forwarded again, resulting in | |
158 | a query which loops many times before being dropped. Upstream | |
159 | servers which loop back are disabled and this event is logged. | |
160 | Thanks to Smoothwall for their sponsorship of this feature. | |

177 | version 2.71 |
178 | Subtle change to error handling to help DNSSEC validation | |
179 | when servers fail to provide NODATA answers for | |
180 | non-existent DS records. | |
181 | ||
182 | Tweak code which removes DNSSEC records from answers when | |
183 | not required. Fixes broken answers when additional section | |
184 | has real records in it. Thanks to Marco Davids for the bug | |

b692f234 SK |
190 | Fix total DNS failure and 100% CPU use if cachesize set to zero, |

195 | version 2.70 |
196 | Fix crash, introduced in 2.69, on TCP request when dnsmasq | |

204 | version 2.69 |
205 | Implement dynamic interface discovery on *BSD. This allows | |

216 | ||
c3a04081 SK |
217 | Add [fd00::] and [fe80::] as special addresses in DHCPv6 |
218 | options, analogous to [::]. [fd00::] is replaced with the | |
219 | actual ULA of the interface on the machine running | |
220 | dnsmasq, [fe80::] with the link-local address. | |
221 | Thanks to Tsachi Kimeldorfer for championing this. | |
222 | ||
613d6c52 SK |
223 | DNSSEC validation and caching. Dnsmasq needs to be |
224 | compiled with this enabled, with | |
225 | ||
226 | make dnsmasq COPTS=-DHAVE_DNSSEC | |
227 | ||
228 | this add dependencies on the nettle crypto library and the | |
229 | gmp maths library. It's possible to have these linked | |
230 | statically with | |
231 | ||
232 | make dnsmasq COPTS='-DHAVE_DNSSEC -DHAVE_DNSSEC_STATIC' | |
233 | ||
198d940a SK |
234 | which bloats the dnsmasq binary, but saves the size of |
235 | the shared libraries which are much bigger. | |
236 | ||
613d6c52 SK |
237 | To enable, DNSSEC, you will need a set of |
238 | trust-anchors. Now that the TLDs are signed, this can be | |
239 | the keys for the root zone, and for convenience they are | |
240 | included in trust-anchors.conf in the dnsmasq | |
241 | distribution. You should of course check that these are | |
242 | legitimate and up-to-date. So, adding | |
243 | ||
244 | conf-file=/path/to/trust-anchors.conf | |
245 | dnssec | |
1ee9be4c | 246 | |
613d6c52 SK |
247 | to your config is all thats needed to get things |
248 | working. The upstream nameservers have to be DNSSEC-capable | |
249 | too, of course. Many ISP nameservers aren't, but the | |
250 | Google public nameservers (8.8.8.8 and 8.8.4.4) are. | |
251 | When DNSSEC is configured, dnsmasq validates any queries | |
252 | for domains which are signed. Query results which are | |
253 | bogus are replaced with SERVFAIL replies, and results | |
254 | which are correctly signed have the AD bit set. In | |
255 | addition, and just as importantly, dnsmasq supplies | |
256 | correct DNSSEC information to clients which are doing | |
257 | their own validation, and caches DNSKEY, DS and RRSIG | |
258 | records, which significantly improve the performance of | |
259 | downstream validators. Setting --log-queries will show | |
260 | DNSSEC in action. | |
261 | ||
198d940a SK |
262 | If a domain is returned from an upstream nameserver without |
263 | DNSSEC signature, dnsmasq by default trusts this. This | |
264 | means that for unsigned zone (still the majority) there | |
265 | is effectively no cost for having DNSSEC enabled. Of course | |
266 | this allows an attacker to replace a signed record with a | |
267 | false unsigned record. This is addressed by the | |
268 | --dnssec-check-unsigned flag, which instructs dnsmasq | |
269 | to prove that an unsigned record is legitimate, by finding | |
270 | a secure proof that the zone containing the record is not | |
271 | signed. Doing this has costs (typically one or two extra | |
272 | upstream queries). It also has a nasty failure mode if | |
273 | dnsmasq's upstream nameservers are not DNSSEC capable. | |
274 | Without --dnssec-check-unsigned using such an upstream | |
275 | server will simply result in not queries being validated; | |
276 | with --dnssec-check-unsigned enabled and a | |
277 | DNSSEC-ignorant upstream server, _all_ queries will fail. | |
278 | ||
279 | Note that DNSSEC requires that the local time is valid and | |
280 | accurate, if not then DNSSEC validation will fail. NTP | |
281 | should be running. This presents a problem for routers | |
282 | without a battery-backed clock. To set the time needs NTP | |
283 | to do DNS lookups, but lookups will fail until NTP has run. | |
284 | To address this, there's a flag, --dnssec-no-timecheck | |
285 | which disables the time checks (only) in DNSSEC. When dnsmasq | |
286 | is started and the clock is not synced, this flag should | |
287 | be used. As soon as the clock is synced, SIGHUP dnsmasq. | |
288 | The SIGHUP clears the cache of partially-validated data and | |
289 | resets the no-timecheck flag, so that all DNSSEC checks | |
290 | henceforward will be complete. | |
291 | ||
613d6c52 SK |
292 | The development of DNSSEC in dnsmasq was started by |
293 | Giovanni Bajo, to whom huge thanks are owed. It has been | |
294 | supported by Comcast, whose techfund grant has allowed for | |
295 | an invaluable period of full-time work to get it to | |
296 | a workable state. | |

de73a497 | 298 | Add --rev-server. Thanks to Dave Taht for suggesting this. |

de73a497 | 302 | |
c8a80487 SK |
303 | Add --local-service. Accept DNS queries only from hosts |
304 | whose address is on a local subnet, ie a subnet for which | |
305 | an interface exists on the server. This option | |
f00690f9 | 306 | only has effect if there are no --interface --except-interface, |
c8a80487 SK |
307 | --listen-address or --auth-server options. It is intended |
308 | to be set as a default on installation, to allow | |
309 | unconfigured installations to be useful but also safe from | |
310 | being used for DNS amplification attacks. | |

316 | Fix wrong RCODE in authoritative DNS replies to PTR queries. The |

324 | version 2.68 |
325 | Use random addresses for DHCPv6 temporary address | |
326 | allocations, instead of algorithmically determined stable | |
327 | addresses. | |
328 | ||
329 | Fix bug which meant that the DHCPv6 DUID was not available | |
330 | in DHCP script runs during the lifetime of the dnsmasq | |
331 | process which created the DUID de-novo. Once the DUID was | |
332 | created and stored in the lease file and dnsmasq | |
333 | restarted, this bug disappeared. | |
334 | ||
335 | Fix bug introduced in 2.67 which could result in erroneous | |
336 | NXDOMAIN returns to CNAME queries. | |
337 | ||
338 | Fix build failures on MacOS X and openBSD. | |
339 | ||
340 | Allow subnet specifications in --auth-zone to be interface | |
341 | names as well as address literals. This makes it possible | |
342 | to configure authoritative DNS when local address ranges | |
343 | are dynamic and works much better than the previous | |
344 | work-around which exempted contructed DHCP ranges from the | |
345 | IP address filtering. As a consequence, that work-around | |
346 | is removed. Under certain circumstances, this change wil | |
347 | break existing configuration: if you're relying on the | |
348 | contructed-range exception, you need to change --auth-zone | |
349 | to specify the same interface as is used to construct your | |
350 | DHCP ranges, probably with a trailing "/6" like this: | |
351 | --auth-zone=example.com,eth0/6 to limit the addresses to | |
352 | IPv6 addresses of eth0. | |
dd9d9ce5 SK |

2329bef5 SK |
364 | |
365 | Check the arrival interface of incoming DNS and TFTP | |
366 | requests via IPv6, even in --bind-interfaces mode. This | |
367 | isn't possible for IPv4 and can generate scary warnings, | |
368 | but as it's always possible for IPv6 (the API always | |
369 | exists) then we should do it always. | |
4c82efc5 VG |
370 | |
371 | Tweak the rules on prefix-lengths in --dhcp-range for | |
372 | IPv6. The new rule is that the specified prefix length | |
373 | must be larger than or equal to the prefix length of the | |
374 | corresponding address on the local interface. | |

381 | |
382 | Repair regression in 2.64. That release stopped sending | |
383 | lease-time information in the reply to DHCPINFORM | |
384 | requests, on the correct grounds that it was a standards | |
385 | violation. However, this broke the dnsmasq-specific | |
386 | dhcp_lease_time utility. Now, DHCPINFORM returns | |
387 | lease-time only if it's specifically requested | |
388 | (maintaining standards) and the dhcp_lease_time utility | |
389 | has been taught to ask for it (restoring functionality). | |

3f2873d4 SK |
400 | |
401 | Handle IPv4 interface-address labels in Linux. These are | |
402 | often used to emulate the old IP-alias addresses. Before, | |
403 | using --interface=eth0 would service all the addresses of | |
404 | eth0, including ones configured as aliases, which appear | |
405 | in ifconfig as eth0:0. Now, only addresses with the label | |
406 | eth0 are active. This is not backwards compatible: if you | |
407 | want to continue to bind the aliases too, you need to add | |
408 | eg. --interface=eth0:0 to the config. | |

411 | operation on non-socket" error on startup with | |
412 | configurations which have exactly one --interface option | |
413 | and do RA but _not_ DHCPv6. Thanks to Trever Adams for the | |
414 | bug report. | |

115ac3e4 SK |
416 | Generalise --interface-name to cope with IPv6 addresses |
417 | and multiple addresses per interface per address family. | |
418 | ||
3e8ed78b SK |
419 | Fix option parsing for --dhcp-host, which was generating a |
420 | spurious error when all seven possible items were | |
421 | included. Thanks to Zhiqiang Wang for the bug report. | |
baa80ae5 SK |
422 | |
423 | Remove restriction on prefix-length in --auth-zone. Thanks | |
424 | to Toke Hoiland-Jorgensen for suggesting this. | |

426 | Log when the maximum number of concurrent DNS queries is |
427 | reached. Thanks to Marcelo Salhab Brogliato for the patch. | |
428 | ||
e2ba0df2 SK |
429 | If wildcards are used in --interface, don't assume that |
430 | there will only ever be one available interface for DHCP | |
431 | just because there is one at start-up. More may appear, so | |
432 | we can't use SO_BINDTODEVICE. Thanks to Natrio for the bug | |
433 | report. | |
434 | ||
b4b93080 SK |
435 | Increase timeout/number of retries in TFTP to accomodate |
436 | AudioCodes Voice Gateways doing streaming writes to flash. | |
437 | Thanks to Damian Kaczkowski for spotting the problem. | |
438 | ||
625ac28c | 439 | Fix crash with empty DHCP string options when adding zero |
3953dcc7 | 440 | terminator. Thanks to Patrick McLean for the bug report. |

442 | Allow hostnames to start with a number, as allowed in |
443 | RFC-1123. Thanks to Kyle Mestery for the patch. | |

3f3adae6 RM |
445 | Fixes to DHCP FQDN option handling: don't terminate FQDN |
446 | if domain not known and allow a FQDN option with blank | |
447 | name to request that a FQDN option is returned in the | |
448 | reply. Thanks to Roy Marples for the patch. | |
449 | ||
d9fb0be8 SK |
450 | Make --clear-on-reload apply to setting upstream servers |
451 | via DBus too. | |
452 | ||
ef1a94ab SK |
453 | When the address which triggered the construction of an |
454 | advertised IPv6 prefix disappears, continue to advertise | |
455 | the prefix for up to 2 hours, with the preferred lifetime | |
456 | set to zero. This satisfies RFC 6204 4.3 L-13 and makes | |
457 | things work better if a prefix disappears without being | |
458 | deprecated first. Thanks to Uwe Schindler for persuasively | |
459 | arguing for this. | |
460 | ||

461 | Fix MAC address enumeration on *BSD. Thanks to Brad Smith |
462 | for the bug report. | |

871d4562 SK |
464 | Support RFC-4242 information-refresh-time options in the |
465 | reply to DHCPv6 information-request. The lease time of the | |
466 | smallest valid dhcp-range is sent. Thanks to Uwe Schindler | |
467 | for suggesting this. | |
468 | ||
edf0bde0 SK |
469 | Make --listen-address higher priority than --except-interface |
470 | in all circumstances. Thanks to Thomas Hood for the bugreport. | |
471 | ||
2937f8a0 SK |
472 | Provide independent control over which interfaces get TFTP |
473 | service. If enable-tftp is given a list of interfaces, then TFTP | |
474 | is provided on those. Without the list, the previous behaviour | |
475 | (provide TFTP to the same interfaces we provide DHCP to) | |
476 | is retained. Thanks to Lonnie Abelbeck for the suggestion. | |
477 | ||
6acef730 SK |
478 | Add --dhcp-relay config option. Many thanks to vtsl.net |
479 | for sponsoring this development. | |
ff7eea27 | 480 | |

481 | Fix crash with empty tag: in --dhcp-range. Thanks to |
482 | Kaspar Schleiser for the bug report. | |
483 | ||
ceae52df SK |
484 | Add "baseline" and "bloatcheck" makefile targets, for |
485 | revealing size changes during development. Thanks to | |
486 | Vladislav Grishenko for the patch. | |
487 | ||
c8f2dd8b SK |
488 | Cope with DHCPv6 clients which send REQUESTs without |
489 | address options - treat them as SOLICIT with rapid commit. | |
490 | ||
89500e31 SK |
491 | Support identification of clients by MAC address in |
492 | DHCPv6. When using a relay, the relay must support RFC | |
493 | 6939 for this to work. It always works for directly | |
494 | connected clients. Thanks to Vladislav Grishenko | |
495 | for prompting this feature. | |
861c8914 SK |
496 | |
497 | Remove the rule for constructed DHCP ranges that the local | |
498 | address must be either the first or last address in the | |
499 | range. This was originally to avoid SLAAC addresses, but | |
500 | we now explicitly autoconfig and privacy addresses instead. | |
89500e31 | 501 | |

510 | inspiration on this. | |
511 | ||
ed4c0767 | 512 | Add --add-subnet configuration, to tell upstream DNS |

d56a604a SK |
519 | Allow A/AAAA records created by --interface-name to be the |
520 | target of --cname. Thanks to Hadmut Danisch for the | |
521 | suggestion. | |
522 | ||
24b5a5d5 SK |
523 | Avoid treating a --dhcp-host which has an IPv6 address |
524 | as eligable for use with DHCPv4 on the grounds that it has | |
525 | no address, and vice-versa. Thanks to Yury Konovalov for | |
526 | spotting the problem. | |

333b2ceb SK |
532 | version 2.66 |
533 | Add the ability to act as an authoritative DNS | |
534 | server. Dnsmasq can now answer queries from the wider 'net | |
535 | with local data, as long as the correct NS records are set | |
536 | up. Only local data is provided, to avoid creating an open | |
537 | DNS relay. Zone transfer is supported, to allow secondary | |
538 | servers to be configured. | |
539 | ||
540 | Add "constructed DHCP ranges" for DHCPv6. This is intended | |
541 | for IPv6 routers which get prefixes dynamically via prefix | |
542 | delegation. With suitable configuration, stateful DHCPv6 | |
543 | and RA can happen automatically as prefixes are delegated | |
544 | and then deprecated, without having to re-write the | |
545 | dnsmasq configuration file or restart the daemon. Thanks to | |
546 | Steven Barth for extensive testing and development work on | |
547 | this idea. | |
71c73ac1 SK |
548 | |
549 | Fix crash on startup on Solaris 11. Regression probably | |
22ce550e SK |
550 | introduced in 2.61. Thanks to Geoff Johnstone for the |
551 | patch. | |
552 | ||
553 | Add code to make behaviour for TCP DNS requests that same | |
554 | as for UDP requests, when a request arrives for an allowed | |
555 | address, but via a banned interface. This change is only | |
556 | active on Linux, since the relevant API is missing (AFAIK) | |
557 | on other platforms. Many thanks to Tomas Hozza for | |
558 | spotting the problem, and doing invaluable discovery of | |
559 | the obscure and undocumented API required for the solution. | |
a21e27bc SK |
560 | |
561 | Don't send the default DHCP option advertising dnsmasq as | |
562 | the local DNS server if dnsmasq is configured to not act | |
563 | as DNS server, or it's configured to a non-standard port. | |
dd1721c7 SK |
564 | |
565 | Add DNSMASQ_CIRCUIT_ID, DNSMASQ_SUBCRIBER_ID, | |
566 | DNSMASQ_REMOTE_ID variables to the environment of the | |
3d77c046 | 567 | lease-change script (and the corresponding Lua). These hold |
dd1721c7 SK |
568 | information inserted into the DHCP request by a DHCP relay |
569 | agent. Thanks to Lakefield Communications for providing a | |
570 | bounty for this addition. | |

4038ae20 SK |
572 | Fixed crash, introduced in 2.64, whilst handling DHCPv6 |

56a1142f SK |
586 | Handle the situation where libc headers define |
587 | SO_REUSEPORT, but the kernel in use doesn't, to cope with | |
588 | the introduction of this option to Linux. Thanks to Rich | |
589 | Felker for the bug report. | |

614 | spotting the problem. | |
615 | ||
12d71ed2 SK |
616 | Finesse the check for /etc/hosts names which conflict with |
617 | DHCP names. Previously a name/address pair in /etc/hosts | |
618 | which didn't match the name/address of a DHCP lease would | |
619 | generate a warning. Now that only happesn if there is not | |
620 | also a match. This allows multiple addresses for a name in | |
621 | /etc/hosts with one of them assigned via DHCP. | |

2022310f SK |
648 | Set SO_REUSEADDRESS and SO_V6ONLY options on the DHCPv6 |
649 | socket, this allows multiple instances of dnsmasq on a | |

668 | Check interface for outgoing unsolicited router | |
669 | advertisements, rather than relying on interface address | |
670 | configuration. Thanks to Gene Czarinski for the patch. | |
29d28dda SK |
671 | |
672 | Handle better attempts to transmit on interfaces which are | |
673 | still doing DAD, and specifically do not just transmit | |
674 | without setting source address and interface, since this | |
675 | can cause very puzzling effects when a router | |
676 | advertisement goes astray. Thanks again to Gene Czarinski. | |

685 | Check that tftp-root directories are accessible before |
686 | start-up. Thanks to Daniel Veillard for the initial patch. | |

8bc4cece SK |
698 | Remove the interface:<interface> argument in --dhcp-range, and |
699 | the interface argument to --enable-tftp. These were a | |
700 | still-born attempt to allow automatic isolated | |
701 | configuration by libvirt, but have never (to my knowledge) | |
702 | been used, had very strange semantics, and have been | |
703 | superceded by other mechanisms. | |

5ae34bf3 SK |
753 | Fixed bug which broke RA scheduling when an interface had |
754 | two addresses in the same network. Thanks to Jim Bos for | |
755 | his help nailing this. | |
756 | ||
eabc6dd7 SK |
757 | version 2.61 |
758 | Re-write interface discovery code on *BSD to use | |
759 | getifaddrs. This is more portable, more straightforward, | |
760 | and allows us to find the prefix length for IPv6 | |
761 | addresses. | |
762 | ||
01d1b8dd SK |
763 | Add ra-names, ra-stateless and slaac keywords for DHCPv6. |
764 | Dnsmasq can now synthesise AAAA records for dual-stack | |
765 | hosts which get IPv6 addresses via SLAAC. It is also now | |
766 | possible to use SLAAC and stateless DHCPv6, and to | |
767 | tell clients to use SLAAC addresses as well as DHCP ones. | |
768 | Thanks to Dave Taht for help with this. | |
7023e382 | 769 | |

770 | Add --dhcp-duid to allow DUID-EN uids to be used. |

8643ec7f SK |
772 | Explicity send DHCPv6 replies to the correct port, instead |
773 | of relying on clients to send requests with the correct | |
774 | source address, since at least one client in the wild gets | |
8358e0f4 | 775 | this wrong. Thanks to Conrad Kostecki for help tracking |
8643ec7f | 776 | this down. |
eabc6dd7 | 777 | |
8643ec7f SK |
778 | Send a preference value of 255 in DHCPv6 replies when |
779 | --dhcp-authoritative is in effect. This tells clients not | |
780 | to wait around for other DHCP servers. | |
781 | ||
782 | Better logging of DHCPv6 options. | |
783 | ||
e759d426 SK |

a9530964 SK |
787 | Invoke the DHCP script with action "tftp" when a TFTP file |
788 | transfer completes. The size of the file, address to which | |
789 | it was sent and complete pathname are supplied. Note that | |
790 | version 2.60 introduced some script incompatibilties | |
791 | associated with DHCPv6, and this is a further change. To | |
792 | be safe, scripts should ignore unknown actions, and if | |
793 | not IPv6-aware, should exit if the environment | |
794 | variable DNSMASQ_IAID is set. The use-case for this is | |
795 | to track netboot/install. Suggestion from Shantanu | |
796 | Gadgil. | |
797 | ||
798 | Update contrib/port-forward/dnsmasq-portforward to reflect | |
799 | the above. | |
800 | ||
801 | Set the environment variable DNSMASQ_LOG_DHCP when running | |
802 | the script id --log-dhcp is in effect, so that script can | |
52d4abf2 SK |
803 | taylor their logging verbosity. Suggestion from Malte |
804 | Forkel. | |
805 | ||
806 | Arrange that addresses specified with --listen-address | |
807 | work even if there is no interface carrying the | |
808 | address. This is chiefly useful for IPv4 loopback | |
809 | addresses, where any address in 127.0.0.0/8 is a valid | |
810 | loopback address, but normally only 127.0.0.1 appears on | |
811 | the lo interface. Thanks to Mathieu Trudel-Lapierre for | |
812 | the idea and initial patch. | |

818 | Add a new DHCP lease time keyword, "deprecated" for |
819 | --dhcp-range. This is only valid for IPv6, and sets the | |
820 | preffered lease time for both DHCP and RA to zero. The | |
821 | effect is that clients can continue to use the address | |
822 | for existing connections, but new connections will use | |
823 | other addresses, if they exist. This makes hitless | |
824 | renumbering at least possible. | |

826 | Fix bug in address6_available() which caused DHCPv6 lease | |
8358e0f4 | 827 | aquisition to fail if more than one dhcp-range in use. |

836 | Don't cache data from non-recursive nameservers, since it |

840 | Call SO_BINDTODEVICE on the DHCP socket(s) when doing DHCP | |
8358e0f4 | 841 | on exactly one interface and --bind-interfaces is set. This |
9380ba70 SK |
842 | makes the OpenStack use-case of one dnsmasq per virtual |

864 | version 2.60 |
865 | Fix compilation problem in Mac OS X Lion. Thanks to Olaf | |
866 | Flebbe for the patch. | |
867 | ||
868 | Fix DHCP when using --listen-address with an IP address | |
869 | which is not the primary address of an interface. | |
870 | ||
871 | Add --dhcp-client-update option. | |
872 | ||
873 | Add Lua integration. Dnsmasq can now execute a DHCP | |
874 | lease-change script written in Lua. This needs to be | |
875 | enabled at compile time by setting HAVE_LUASCRIPT in | |
876 | src/config.h or running "make COPTS=-DHAVE_LUASCRIPT" | |
877 | Thanks to Jan-Piet Mens for the idea and proof-of-concept | |
878 | implementation. | |
879 | ||
880 | Tidied src/config.h to distinguish between | |
881 | platform-dependent compile-time options which are selected | |
882 | automatically, and builder-selectable compile time | |
883 | options. Document the latter better, and describe how to | |
884 | set them from the make command line. | |
885 | ||
886 | Tidied up IPPROTO_IP/SOL_IP (and IPv6 equivalent) | |
887 | confusion. IPPROTO_IP works everywhere now. | |

751d6f4a SK |
906 | Allow the TFP server or boot server in --pxe-service, to |
907 | be a domain name instead of an IP address. This allows for | |
908 | round-robin to multiple servers, in the same way as | |
909 | --dhcp-boot. A good suggestion from Cristiano Cumer. | |
910 | ||
fdacfb01 SK |
911 | Support BUILDDIR variable in the Makefile. Allows builds |
912 | for multiple archs from the same source tree with eg. | |
913 | make BUILDDIR=linux (relative to dnsmasq tree) | |
914 | make BUILDDIR=/tmp/openbsd (absolute path) | |
e5ffdb9c | 915 | If BUILDDIR is not set, compilation happens in the src |
b36ae194 SK |
916 | directory, as before. Suggestion from Mark Mitchell. |
917 | ||
fdacfb01 SK |
918 | Support DHCPv6. Support is there for the sort of things |
919 | the existing v4 server does, including tags, options, | |
920 | static addresses and relay support. Missing is prefix | |
921 | delegation, which is probably not required in the dnsmasq | |
922 | niche, and an easy way to accept prefix delegations from | |
923 | an upstream DHCPv6 server, which is. Future plans include | |
924 | support for DHCPv6 router option and MAC address option | |
925 | (to make selecting clients by MAC address work like IPv4). | |
926 | These will be added as the standards mature. | |
927 | This code has been tested, but this is the first release, | |
928 | so don't bet the farm on it just yet. Many thanks to all | |
929 | testers who have got it this far. | |
1adadf58 | 930 | |
ac8540c3 SK |
931 | Support IPv6 router advertisements. This is a |
932 | simple-minded implementation, aimed at providing the | |
933 | vestigial RA needed to go alongside IPv6. Is picks up | |
934 | configuration from the DHCPv6 conf, and should just need | |
935 | enabling with --enable-ra. | |
936 | ||
552af8b9 SK |
937 | Fix long-standing wrinkle with --localise-queries that |
938 | could result in wrong answers when DNS packets arrive | |

74c95c25 | 947 | version 2.59 |
c72daea8 SK |
948 | Fix regression in 2.58 which caused failure to start up |
949 | with some combinations of dnsmasq config and IPv6 kernel | |
950 | network config. Thanks to Brielle Bruns for the bug | |
951 | report. | |
952 | ||
953 | Improve dnsmasq's behaviour when network interfaces are | |
954 | still doing duplicate address detection (DAD). Previously, | |
955 | dnsmasq would wait up to 20 seconds at start-up for the | |
956 | DAD state to terminate. This is broken for bridge | |
957 | interfaces on recent Linux kernels, which don't start DAD | |
958 | until the bridge comes up, and so can take arbitrary | |
959 | time. The new behaviour lets dnsmasq poll for an arbitrary | |
960 | time whilst providing service on other interfaces. Thanks | |
961 | to Stephen Hemminger for pointing out the problem. | |
74c95c25 SK |
962 | |
963 | ||
7de060b0 SK |
964 | version 2.58 |
965 | Provide a definition of the SA_SIZE macro where it's | |
966 | missing. Fixes build failure on openBSD. | |
967 | ||
968 | Don't include a zero terminator at the end of messages | |
969 | sent to /dev/log when /dev/log is a datagram socket. | |
970 | Thanks to Didier Rabound for spotting the problem. | |
971 | ||
972 | Add --dhcp-sequential-ip flag, to force allocation of IP | |
973 | addresses in ascending order. Note that the default | |
974 | pseudo-random mode is in general better but some | |
975 | server-deployment applications need this. | |
976 | ||
977 | Fix problem where a server-id of 0.0.0.0 is sent to a | |
978 | client when a dhcp-relay is in use if a client renews a | |
979 | lease after dnsmasq restart and before any clients on the | |
980 | subnet get a new lease. Thanks to Mike Ruiz for assistance | |
981 | in chasing this one down. | |
982 | ||
983 | Don't return NXDOMAIN to an AAAA query if we have CNAME | |
984 | which points to an A record only: NODATA is the correct | |
985 | reply in this case. Thanks to Tom Fernandes for spotting | |
986 | the problem. | |
987 | ||
988 | Relax the need to supply a netmask in --dhcp-range for | |
989 | networks which use a DHCP relay. Whilst this is still | |
990 | desireable, in the absence of a netmask dnsmasq will use | |
991 | a default based on the class (A, B, or C) of the address. | |
992 | This should at least remove a cause of mysterious failure | |
993 | for people using RFC1918 addresses and relays. | |
994 | ||
995 | Add support for Linux conntrack connection marking. If | |
996 | enabled with --conntrack, the connection mark for incoming | |
997 | DNS queries will be copied to the outgoing connections | |
998 | used to answer those queries. This allows clever firewall | |
999 | and accounting stuff. Only available if dnsmasq is | |
1000 | compiled with HAVE_CONNTRACK and adds a dependency on | |
1001 | libnetfilter-conntrack. Thanks to Ed Wildgoose for the | |
1002 | initial idea, testing and sponsorship of this function. | |
1003 | ||
1004 | Provide a sane error message when someone attempts to | |
1005 | match a tag in --dhcp-host. | |
1006 | ||
1007 | Tweak the behaviour of --domain-needed, to avoid problems | |
1008 | with recursive nameservers downstream of dnsmasq. The new | |
1009 | behaviour only stops A and AAAA queries, and returns | |
1010 | NODATA rather than NXDOMAIN replies. | |
1011 | ||
1012 | Efficiency fix for very large DHCP configurations, thanks | |
1013 | to James Gartrell and Mike Ruiz for help with this. | |
1014 | ||
1015 | Allow the TFTP-server address in --dhcp-boot to be a | |
1016 | domain-name which is looked up in /etc/hosts. This can | |
1017 | give multiple IP addresses which are used round-robin, | |
1018 | thus doing TFTP server load-balancing. Thanks to Sushil | |
1019 | Agrawal for the patch. | |
1020 | ||
1021 | When two tagged dhcp-options for a particular option | |
1022 | number are both valid, use the one which is valid without | |
1023 | a tag from the dhcp-range. Allows overriding of the value | |
1024 | of a DHCP option for a particular host as well as | |
1025 | per-network values. So | |
1026 | --dhcp-range=set:interface1,...... | |
1027 | --dhcp-host=set:myhost,..... | |
1028 | --dhcp-option=tag:interface1,option:nis-domain,"domain1" | |
1029 | --dhcp-option=tag:myhost,option:nis-domain,"domain2" | |
1030 | will set the NIS-domain to domain1 for hosts in the range, but | |
1031 | override that to domain2 for a particular host. | |
1032 | ||
1033 | Fix bug which resulted in truncated files and timeouts for | |
1034 | some TFTP transfers. The bug only occurs with netascii | |
1035 | transfers and needs an unfortunate relationship between | |
1036 | file size, blocksize and the number of newlines in the | |
1037 | last block before it manifests itself. Many thanks to | |
1038 | Alkis Georgopoulos for spotting the problem and providing | |
1039 | a comprehensive test-case. | |
1040 | ||
1041 | Fix regression in TFTP server on *BSD platforms introduced | |
1042 | in version 2.56, due to confusion with sockaddr | |
de604c18 | 1043 | length. Many thanks to Loic Pefferkorn for finding this. |
7de060b0 SK |
1044 | |
1045 | Support scope-ids in IPv6 addresses of nameservers from | |
1046 | /etc/resolv.conf and in --server options. Eg | |
1047 | nameserver fe80::202:a412:4512:7bbf%eth0 or | |
1048 | server=fe80::202:a412:4512:7bbf%eth0. Thanks to | |

572b41eb SK |
1056 | version 2.57 |
1057 | Add patches to allow build under Android. | |
1058 | ||
1059 | Provide our own header for the DNS protocol, rather than | |
1060 | relying on arpa/nameser.h. This has proved more or less | |
1061 | defective over the years and the final straw is that it's | |
1062 | effectively empty on Android. | |
1063 | ||
1064 | Fix regression in 2.56 which caused hex constants in | |
1065 | configuration to be rejected if they contain the '*' | |
1066 | wildcard. | |
1067 | ||
1068 | Correct wrong casts of arguments to ctype.h functions, | |
1069 | isdigit(), isxdigit() etc. Thanks to Matthias Andree for | |
1070 | spotting this. | |
1071 | ||
1072 | Allow build with IDN support independently from i18n. | |
1073 | IDN support continues to be included automatically | |
1074 | when i18n is included. | |
1075 | 'make COPTS=-DHAVE_IDN' is the magic incantation. | |
1076 | ||
1077 | Modify check on extraneous command line junk (added in | |
1078 | 2.56) so that it doesn't complain about extra _empty_ | |
1079 | arguments. Otherwise this breaks libvirt. | |
1080 | ||
1081 | ||
28866e95 SK |
1082 | version 2.56 |
1083 | Add a patch to allow dnsmasq to get interface names right in a | |
1084 | Solaris zone. Thanks to Dj Padzensky for this. | |
1085 | ||
1086 | Improve data-type parsing heuristics so that | |
1087 | --dhcp-option=option:domain-search,. | |
1088 | treats the value as a string and not an IP address. | |
1089 | Thanks to Clemens Fischer for spotting that. | |
1090 | ||
1091 | Add IPv6 support to the TFTP server. Many thanks to Jan | |
1092 | 'RedBully' Seiffert for the patches. | |
1093 | ||
1094 | Log DNS queries at level LOG_INFO, rather then | |
1095 | LOG_DEBUG. This makes things consistent with DHCP | |
1096 | logging. Thanks to Adam Pribyl for spotting the problem. | |
1097 | ||
1098 | Ensure that dnsmasq terminates cleanly when using | |
1099 | --syslog-async even if it cannot make a connection to the | |
1100 | syslogd. | |
1101 | ||
1102 | Add --add-mac option. This is to support currently | |
1103 | experimental DNS filtering facilities. Thanks to Benjamin | |
1104 | Petrin for the orignal patch. | |
1105 | ||
1106 | Fix bug which meant that tags were ignored in dhcp-range | |
1107 | configuration specifying PXE-proxy service. Thanks to | |
1108 | Cristiano Cumer for spotting this. | |
1109 | ||
1110 | Raise an error if there is extra junk, not part of an | |
1111 | option, on the command line. | |
1112 | ||
1113 | Flag a couple of log messages in cache.c as coming from | |
1114 | the DHCP subsystem. Thanks to Olaf Westrik for the patch. | |
1115 | ||
1116 | Omit timestamps from logs when a) logging to stderr and | |
1117 | b) --keep-in-forground is set. The logging facility on the | |
1118 | other end of stderr can be assumned to supply them. Thanks | |
1119 | to John Hallam for the patch. | |
1120 | ||
1121 | Don't complain about strings longer than 255 characters in | |
1122 | --txt-record, just split the long strings into 255 | |
1123 | character chunks instead. | |
1124 | ||
1125 | Fix crash on double-free. This bug can only happen when | |
1126 | dhcp-script is in use and then only in rare circumstances | |
1127 | triggered by high DHCP transaction rate and a slow | |
1128 | script. Thanks to Ferenc Wagner for finding the problem. | |
1129 | ||
1130 | Only log that a file has been sent by TFTP after the | |
1131 | transfer has completed succesfully. | |
1132 | ||
1133 | A good suggestion from Ferenc Wagner: extend | |
1134 | the --domain option to allow this sort of thing: | |
1135 | --domain=thekelleys.org.uk,192.168.0.0/24,local | |
1136 | which automatically creates | |
1137 | --local=/thekelleys.org.uk/ | |
1138 | --local=/0.168.192.in-addr.arpa/ | |
1139 | ||
1140 | Tighten up syntax checking of hex contants in the config | |
1141 | file. Thanks to Fred Damen for spotting this. | |
1142 | ||
1143 | Add dnsmasq logo/icon, contributed by Justin Swift. Many | |
1144 | thanks for that. | |
1145 | ||
1146 | Never cache DNS replies which have the 'cd' bit set, or | |
1147 | which result from queries forwarded with the 'cd' bit | |
1148 | set. The 'cd' bit instructs a DNSSEC validating server | |
1149 | upstream to ignore signature failures and return replies | |
1150 | anyway. Without this change it's possible to pollute the | |
1151 | dnsmasq cache with bad data by making a query with the | |
1152 | 'cd' bit set and subsequent queries would return this data | |
1153 | without its being marked as suspect. Thanks to Anders | |
1154 | Kaseorg for pointing out this problem. | |
1155 | ||
1156 | Add --proxy-dnssec flag, for compliance with RFC | |
1157 | 4035. Dnsmasq will now clear the 'ad' bit in answers returned | |
1158 | from upstream validating nameservers unless this option is | |
1159 | set. | |
1160 | ||
1161 | Allow a filename of "-" for --conf-file to read | |
1162 | stdin. Suggestion from Timothy Redaelli. | |
1163 | ||
1164 | Rotate the order of SRV records in replies, to provide | |
1165 | round-robin load balancing when all the priorities are | |
1166 | equal. Thanks to Peter McKinney for the suggestion. | |
1167 | ||
1168 | Edit | |
1169 | contrib/MacOSX-launchd/uk.org.thekelleys.dnsmasq.plist | |
1170 | so that it doesn't log all queries to a file by | |
1171 | default. Thanks again to Peter McKinney. | |
1172 | ||
1173 | By default, setting an IPv4 address for a domain but not | |
1174 | an IPv6 address causes dnsmasq to return | |
1175 | an NODATA reply for IPv6 (or vice-versa). So | |
1176 | --address=/google.com/1.2.3.4 stops IPv6 queries for | |
1177 | *google.com from being forwarded. Make it possible to | |
1178 | override this behaviour by defining the sematics if the | |
1179 | same domain appears in both --server and --address. | |
1180 | In that case, the --address has priority for the address | |
1181 | family in which is appears, but the --server has priority | |
1182 | of the address family which doesn't appear in --adddress | |
1183 | So: | |
1184 | --address=/google.com/1.2.3.4 | |
1185 | --server=/google.com/# | |
1186 | will return 1.2.3.4 for IPv4 queries for *.google.com but | |
1187 | forward IPv6 queries to the normal upstream nameserver. | |
1188 | Similarly when setting an IPv6 address | |
1189 | only this will allow forwarding of IPv4 queries. Thanks to | |
1190 | William for pointing out the need for this. | |
1191 | ||
1192 | Allow more than one --dhcp-optsfile and --dhcp-hostsfile | |
1193 | and make them understand directories as arguments in the | |
1194 | same way as --addn-hosts. Suggestion from John Hanks. | |
1195 | ||
1196 | Ignore rebinding requests for leases we don't know | |
1197 | about. Rebind is broadcast, so we might get to overhear a | |
1198 | request meant for another DHCP server. NAKing this is | |
1199 | wrong. Thanks to Brad D'Hondt for assistance with this. | |
1200 | ||

1237 | which can set a tag does so by adding "set:<tag>" and | |
1238 | every configuration item which is conditional on a tag is | |
1239 | made so by "tag:<tag>". The NOT operator changes to '!', | |
1240 | which is a bit more intuitive too. Dhcp-host directives | |
1241 | can set more than one tag now. The old '#' NOT, | |
1242 | "net:" prefix and no-prefixes are still honoured, so | |
1243 | no existing config file needs to be changed, but | |
1244 | the documentation and new-style config files should be | |
1245 | much less confusing. | |
1246 | ||
1247 | Added --tag-if to allow boolean operations on tags. | |
1248 | This allows complicated logic to be clearer and more | |
1249 | general. A great suggestion from Richard Voigt. | |
1250 | ||
1251 | Add broadcast/unicast information to DHCP logging. | |
1252 | ||
1253 | Allow --dhcp-broadcast to be unconditional. | |
1254 | ||
1255 | Fixed incorrect behaviour with NOT <tag> conditionals in | |
1256 | dhcp-options. Thanks to Max Turkewitz for assistance | |
1257 | finding this. | |
1258 | ||
1259 | If we send vendor-class encapsulated options based on the | |
1260 | vendor-class supplied by the client, and no explicit | |
1261 | vendor-class option is given, echo back the vendor-class | |
1262 | from the client. | |
1263 | ||
1264 | Fix bug which stopped dnsmasq from matching both a | |
1265 | circuitid and a remoteid. Thanks to Ignacio Bravo for | |
1266 | finding this. | |
1267 | ||
1268 | Add --dhcp-proxy, which makes it possible to configure | |
1269 | dnsmasq to use a DHCP relay agent as a full proxy, with | |
1270 | all DHCP messages passing through the proxy. This is | |
1271 | useful if the relay adds extra information to the packets | |
1272 | it forwards, but cannot be configured with the RFC 5107 | |
1273 | server-override option. | |
1274 | ||
1275 | Added interface:<iface name> part to dhcp-range. The | |
1276 | semantics of this are very odd at first sight, but it | |
1277 | allows a single line of the form | |
1278 | dhcp-range=interface:virt0,192.168.0.4,192.168.0.200 | |
1279 | to be added to dnsmasq configuration which then supplies | |
1280 | DHCP and DNS services to that interface, without affecting | |
1281 | what services are supplied to other interfaces and | |
1282 | irrespective of the existance or lack of | |
1283 | interface=<interface> | |
1284 | lines elsewhere in the dnsmasq configuration. The idea is | |
1285 | that such a line can be added automatically by libvirt | |
1286 | or equivalent systems, without disturbing any manual | |
1287 | configuration. | |
1288 | ||
1289 | Similarly to the above, allow --enable-tftp=<interface> | |
1290 | ||
1291 | Allow a TFTP root to be set separately for requests via | |
1292 | different interfaces, --tftp-root=<path>,<interface> | |
1293 | ||
1294 | Correctly handle and log clashes between CNAMES and | |
1295 | DNS names being given to DHCP leases. This fixes a bug | |
1296 | which caused nonsense IP addresses to be logged. Thanks to | |
1297 | Sergei Zhirikov for finding and analysing the problem. | |
1298 | ||
1299 | Tweak flush_log so as to avoid leaving the log | |
1300 | file in non-blocking mode. O_NONBLOCK is a property of the | |
1301 | file, not the process/descriptor. | |
1302 | ||
1303 | Fix contrib/Solaris10/create_package | |
1304 | (/usr/man -> /usr/share/man) Thanks to Vita Batrla. | |
1305 | ||
1306 | Fix a problem where, if a client got a lease, then went | |
1307 | to another subnet and got another lease, then moved back, | |
1308 | it couldn't resume the old lease, but would instead get | |
1309 | a new address. Thanks to Leonardo Rodrigues for spotting | |
1310 | this and testing the fix. | |
1311 | ||
1312 | Fix weird bug which sometimes omitted certain characters | |
1313 | from the start of quoted strings in dhcp-options. Thanks | |
1314 | to Dayton Turner for spotting the problem. | |
1315 | ||
1316 | Add facility to redirect some domains to the standard | |
1317 | upstream servers: this allows something like | |
1318 | --server=/google.com/1.2.3.4 --server=/www.google.com/# | |
1319 | which will send queries for *.google.com to 1.2.3.4, | |
1320 | except *www.google.com which will be forwarded as usual. | |
1321 | Thanks to AJ Weber for prompting this addition. | |
1322 | ||
1323 | Improve the hash-algorithm used to generate IP addresses | |
1324 | from MAC addresses during initial DHCP address | |
1325 | allocation. This improves performance when large numbers | |
1326 | of hosts with similar MAC addresses all try and get an IP | |
1327 | address at the same time. Thanks to Paul Smith for his | |
1328 | work on this. | |
1329 | ||
1330 | Tweak DHCP code so that --bridge-interface can be used to | |
1331 | select which IP alias of an interface should be used for | |
1332 | DHCP purposes on Linux. If eth0 has an alias eth0:dhcp | |
1333 | then adding --bridge-interface=eth0:dhcp,eth0 will use | |
1334 | the address of eth0:dhcp to determine the correct subnet | |
1335 | for DHCP address allocation. Thanks to Pawel Golaszewski | |
1336 | for prompting this and Eric Cooper for further testing. | |
1337 | ||
1338 | Add --dhcp-generate-names. Suggestion by Ferenc Wagner. | |
1339 | ||
1340 | Tweak DNS server selection algorithm when there is more | |
1341 | than one server available for a domain, eg. | |
1342 | --server=/mydomain/1.1.1.1 | |
1343 | --server=/mydomain/2.2.2.2 | |
1344 | Thanks to Alberto Cuesta-Canada for spotting a weakness | |
1345 | here. | |
1346 | ||
1347 | Add --max-ttl. Thanks to Fredrik Ringertz for the patch. | |
1348 | ||
1349 | Allow --log-facility=- to force all logging to | |
1350 | stderr. Suggestion from Clemens Fischer. | |
1351 | ||
1352 | Fix regression which caused configuration like | |
1353 | --address=/.domain.com/1.2.3.4 to be rejected. The dot to the | |
1354 | left of the domain has been implied and not required for a | |
1355 | long time, but it should be accepted for backward | |
1356 | compatibility. Thanks to Andrew Burcin for spotting this. | |
1357 | ||
1358 | Add --rebind-domain-ok and --rebind-localhost-ok. | |
1359 | Suggestion from Clemens Fischer. | |
1360 | ||
1361 | Log replies to queries of type TXT, when --log-queries | |
1362 | is set. | |
1363 | ||
1364 | Fix compiler warnings when compiled with -DNO_DHCP. Thanks | |
1365 | to Shantanu Gadgil for the patch. | |
1366 | ||
1367 | Updated French translation. Thanks to Gildas Le Nadan. | |
1368 | ||
1369 | Updated Polish translation. Thanks to Jan Psota. | |
1370 | ||
1371 | Updated German translation. Thanks to Matthias Andree. | |
1372 | ||
1373 | Added contrib/static-arp, thanks to Darren Hoo. | |
1374 | ||
1375 | Fix corruption of the domain when a name from /etc/hosts | |
1376 | overrides one supplied by a DHCP client. Thanks to Fedor | |
1377 | Kozhevnikov for spotting the problem. | |
1378 | ||
1379 | Updated Spanish translation. Thanks to Chris Chatham. | |
1380 | ||
1381 | ||
316e2730 SK |
1382 | version 2.52 |
1383 | Work around a Linux kernel bug which insists that the | |
1384 | length of the option passed to setsockopt must be at least | |
1385 | sizeof(int) bytes, even if we're calling SO_BINDTODEVICE | |
1386 | and the device name is "lo". Note that this is fixed | |
1387 | in kernel 2.6.31, but the workaround is harmless and | |
1388 | allows earlier kernels to be used. Also fix dnsmasq | |
1389 | bug which reported the wrong address when this failed. | |
1390 | Thanks to Fedor for finding this. | |
1391 | ||
1392 | The API for IPv6 PKTINFO changed around Linux kernel | |
1393 | 2.6.14. Workaround the case where dnsmasq is compiled | |
1394 | against newer headers, but then run on an old kernel: | |
1395 | necessary for some *WRT distros. | |
1396 | ||
1397 | Re-read the set of network interfaces when re-loading | |
1398 | /etc/resolv.conf if --bind-interfaces is not set. This | |
1399 | handles the case that loopback interfaces do not exist | |
1400 | when dnsmasq is first started. | |
1401 | ||
1402 | Tweak the PXE code to support port 4011. This should | |
1403 | reduce broadcasts and make things more reliable when other | |
1404 | servers are around. It also improves inter-operability | |
1405 | with certain clients. | |
1406 | ||
1407 | Make a pxe-service configuration with no filename or boot | |
1408 | service type legal: this does a local boot. eg. | |
1409 | pxe-service=x86PC, "Local boot" | |
1410 | ||
1411 | Be more conservative in detecting "A for A" | |
1412 | queries. Dnsmasq checks if the name in a type=A query looks | |
1413 | like a dotted-quad IP address and answers the query itself | |
1414 | if so, rather than forwarding it. Previously dnsmasq | |
1415 | relied in the library function inet_addr() to convert | |
1416 | addresses, and that will accept some things which are | |
1417 | confusing in this context, like 1.2.3 or even just | |
1418 | 1234. Now we only do A for A processing for four decimal | |
1419 | numbers delimited by dots. | |
1420 | ||
1421 | A couple of tweaks to fix compilation on Solaris. Thanks | |
1422 | to Joel Macklow for help with this. | |
1423 | ||
1424 | Another Solaris compilation tweak, needed for Solaris | |
1425 | 2009.06. Thanks to Lee Essen for that. | |
1426 | ||
1427 | Added extract packaging stuff from Lee Essen to | |
1428 | contrib/Solaris10. | |
1429 | ||
1430 | Increased the default limit on number of leases to 1000 | |
1431 | (from 150). This is mainly a defence against DoS attacks, | |
1432 | and for the average "one for two class C networks" | |
1433 | installation, IP address exhaustion does that just as | |
1434 | well. Making the limit greater than the number of IP | |
1435 | addresses available in such an installation removes a | |
1436 | surprise which otherwise can catch people out. | |
1437 | ||
1438 | Removed extraneous trailing space in the value of the | |
1439 | DNSMASQ_TIME_REMAINING DNSMASQ_LEASE_LENGTH and | |
1440 | DNSMASQ_LEASE_EXPIRES environment variables. Thanks to | |
1441 | Gildas Le Nadan for spotting this. | |
1442 | ||
1443 | Provide the network-id tags for a DHCP transaction to | |
1444 | the lease-change script in the environment variable | |
1445 | DNSMASQ_TAGS. A good suggestion from Gildas Le Nadan. | |
1446 | ||
1447 | Add support for RFC3925 "Vendor-Identifying Vendor | |
1448 | Options". The syntax looks like this: | |
1449 | --dhcp-option=vi-encap:<enterprise number>, ......... | |
1450 | ||
1451 | Add support to --dhcp-match to allow matching against | |
1452 | RFC3925 "Vendor-Identifying Vendor Classes". The syntax | |
1453 | looks like this: | |
1454 | --dhcp-match=tag,vi-encap<enterprise number>, <value> | |
1455 | ||
1456 | Add some application specific code to assist in | |
1457 | implementing the Broadband forum TR069 CPE-WAN | |
1458 | specification. The details are in contrib/CPE-WAN/README | |
1459 | ||
1460 | Increase the default DNS packet size limit to 4096, as | |
1461 | recommended by RFC5625 section 4.4.3. This can be | |
1462 | reconfigured using --edns-packet-max if needed. Thanks to | |
1463 | Francis Dupont for pointing this out. | |
1464 | ||
8ef5ada2 | 1465 | Rewrite query-ids even for TSIG signed packets, since |
316e2730 SK |
1466 | this is allowed by RFC5625 section 4.5. |
1467 | ||
1468 | Use getopt_long by default on OS X. It has been supported | |
1469 | since version 10.3.0. Thanks to Arek Dreyer for spotting | |
1470 | this. | |
1471 | ||
1472 | Added up-to-date startup configuration for MacOSX/launchd | |
1473 | in contrib/MacOSX-launchd. Thanks to Arek Dreyer for | |
1474 | providing this. | |
1475 | ||
1476 | Fix link error when including Dbus but excluding DHCP. | |
1477 | Thanks to Oschtan for the bug report. | |
1478 | ||
1479 | Updated French translation. Thanks to Gildas Le Nadan. | |
1480 | ||
1481 | Updated Polish translation. Thanks to Jan Psota. | |
1482 | ||
1483 | Updated Spanish translation. Thanks to Chris Chatham. | |
1484 | ||
8ef5ada2 SK |
1485 | Fixed confusion about domains, when looking up DHCP hosts |
1486 | in /etc/hosts. This could cause spurious "Ignoring | |
1487 | domain..." messages. Thanks to Fedor Kozhevnikov for | |
1488 | finding and analysing the problem. | |
316e2730 | 1489 | |
8ef5ada2 | 1490 | |
1f15b81d SK |
1491 | version 2.51 |
1492 | Add support for internationalised DNS. Non-ASCII characters | |
1493 | in domain names found in /etc/hosts, /etc/ethers and | |
1494 | /etc/dnsmasq.conf will be correctly handled by translation to | |
1495 | punycode, as specified in RFC3490. This function is only | |
1496 | available if dnsmasq is compiled with internationalisation | |
1497 | support, and adds a dependency on GNU libidn. Without i18n | |
1498 | support, dnsmasq continues to be compilable with just | |
1499 | standard tools. Thanks to Yves Dorfsman for the | |
1500 | suggestion. | |
1501 | ||
1502 | Add two more environment variables for lease-change scripts: | |
1503 | First, DNSMASQ_SUPPLIED_HOSTNAME; this is set to the hostname | |
1504 | supplied by a client, even if the actual hostname used is | |
1505 | over-ridden by dhcp-host or dhcp-ignore-names directives. | |
1506 | Also DNSMASQ_RELAY_ADDRESS which gives the address of | |
1507 | a DHCP relay, if used. | |
1508 | Suggestions from Michael Rack. | |
1509 | ||
1510 | Fix regression which broke echo of relay-agent | |
1511 | options. Thanks to Michael Rack for spotting this. | |
1512 | ||
1513 | Don't treat option 67 as being interchangeable with | |
1514 | dhcp-boot parameters if it's specified as | |
1515 | dhcp-option-force. | |
1516 | ||
1517 | Make the code to call scripts on lease-change compile-time | |
1518 | optional. It can be switched off by editing src/config.h | |
1519 | or building with "make COPTS=-DNO_SCRIPT". | |
1520 | ||
1521 | Make the TFTP server cope with filenames from Windows/DOS | |
1522 | which use '\' as pathname separator. Thanks to Ralf for | |
1523 | the patch. | |
1524 | ||
1525 | Updated Polish translation. Thanks to Jan Psota. | |
1526 | ||
1527 | Warn if an IP address is duplicated in /etc/ethers. Thanks | |
1528 | to Felix Schwarz for pointing this out. | |
1529 | ||
1530 | Teach --conf-dir to take an option list of file suffices | |
1531 | which will be ignored when scanning the directory. Useful | |
1532 | for backup files etc. Thanks to Helmut Hullen for the | |
1533 | suggestion. | |
1534 | ||
1535 | Add new DHCP option named tftpserver-address, which | |
1536 | corresponds to the third argument of dhcp-boot. This | |
1537 | allows the complete functionality of dhcp-boot to be | |
1538 | replicated with dhcp-option. Useful when using | |
1539 | dhcp-optsfile. | |
1540 | ||
1541 | Test which upstream nameserver to use every 10 seconds | |
1542 | or 50 queries and not just when a query times out and | |
1543 | is retried. This should improve performance when there | |
1544 | is a slow nameserver in the list. Thanks to Joe for the | |
1545 | suggestion. | |
1546 | ||
1547 | Don't do any PXE processing, even for clients with the | |
1548 | correct vendorclass, unless at least one pxe-prompt or | |
1549 | pxe-service option is given. This stops dnsmasq | |
1550 | interfering with proxy PXE subsystems when it is just | |
1551 | the DHCP server. Thanks to Spencer Clark for spotting this. | |
1552 | ||
1553 | Limit the blocksize used for TFTP transfers to a value | |
1554 | which avoids packet fragmentation, based on the MTU of the | |
1555 | local interface. Many netboot ROMs can't cope with | |
1556 | fragmented packets. | |
1557 | ||
1558 | Honour dhcp-ignore configuration for PXE and proxy-PXE | |
1559 | requests. Thanks to Niels Basjes for the bug report. | |
1560 | ||
1561 | Updated French translation. Thanks to Gildas Le Nadan. | |
1562 | ||
1563 | ||
77e94da7 | 1564 | version 2.50 |
1f15b81d | 1565 | Fix security problem which allowed any host permitted to |
77e94da7 SK |
1566 | do TFTP to possibly compromise dnsmasq by remote buffer |
1567 | overflow when TFTP enabled. Thanks to Core Security | |
1568 | Technologies and Iván Arce, Pablo Hernán Jorge, Alejandro | |
1569 | Pablo Rodriguez, Martín Coco, Alberto Soliño Testa and | |
1570 | Pablo Annetta. This problem has Bugtraq id: 36121 | |
1571 | and CVE: 2009-2957 | |
1572 | ||
1573 | Fix a problem which allowed a malicious TFTP client to | |
1574 | crash dnsmasq. Thanks to Steve Grubb at Red Hat for | |
1575 | spotting this. This problem has Bugtraq id: 36120 and | |
1576 | CVE: 2009-2958 | |
1577 | ||
1578 | ||
03a97b61 SK |
1579 | version 2.49 |
1580 | Fix regression in 2.48 which disables the lease-change | |
1581 | script. Thanks to Jose Luis Duran for spotting this. | |
1582 | ||
1583 | Log TFTP "file not found" errors. These were not logged, | |
1584 | since a normal PXELinux boot generates many of them, but | |
1585 | the lack of the messages seems to be more confusing than | |
1586 | routinely seeing them when there is no real error. | |
1587 | ||
1588 | Update Spanish translation. Thanks to Chris Chatham. | |
1589 | ||
1590 | ||
7622fc06 SK |
1591 | version 2.48 |
1592 | Archived the extensive, backwards, changelog to | |
1593 | CHANGELOG.archive. The current changelog now runs from | |
1594 | version 2.43 and runs conventionally. | |
9e4abcb5 | 1595 | |
7622fc06 SK |
1596 | Fixed bug which broke binding of servers to physical |
1597 | interfaces when interface names were longer than four | |
1598 | characters. Thanks to MURASE Katsunori for the patch. | |
9e4abcb5 | 1599 | |
7622fc06 SK |
1600 | Fixed netlink code to check that messages come from the |
1601 | correct source, and not another userspace process. Thanks | |
1602 | to Steve Grubb for the patch. | |
9e4abcb5 | 1603 | |
7622fc06 SK |
1604 | Maintainability drive: removed bug and missing feature |
1605 | workarounds for some old platforms. Solaris 9, OpenBSD | |
1606 | older than 4.1, Glibc older than 2.2, Linux 2.2.x and | |
1607 | DBus older than 1.1.x are no longer supported. | |
9e4abcb5 | 1608 | |
7622fc06 SK |
1609 | Don't read included configuration files more than once: |
1610 | allows complex configuration structures without problems. | |
9e4abcb5 | 1611 | |
7622fc06 SK |
1612 | Mark log messages from the various subsystems in dnsmasq: |
1613 | messages from the DHCP subsystem now have the ident string | |
1614 | "dnsmasq-dhcp" and messages from TFTP have ident | |
1615 | "dnsmasq-tftp". Thanks to Olaf Westrik for the patch. | |
9e4abcb5 | 1616 | |
7622fc06 SK |
1617 | Fix possible infinite DHCP protocol loop when an IP |
1618 | address nailed to a hostname (not a MAC address) and a | |
1619 | host sometimes provides the name, sometimes not. | |
9e4abcb5 | 1620 | |
7622fc06 SK |
1621 | Allow --addn-hosts to take a directory: all the files |
1622 | in the directory are read. Thanks to Phil Cornelius for | |
1623 | the suggestion. | |
9e4abcb5 | 1624 | |
7622fc06 | 1625 | Support --bridge-interface on all platforms, not just BSD. |
1ab84e2f | 1626 | |
7622fc06 SK |
1627 | Added support for advanced PXE functions. It's now |
1628 | possible to define a prompt and menu options which will | |
1629 | be displayed when a client PXE boots. It's also possible to | |
1630 | hand-off booting to other boot servers. Proxy-DHCP, where | |
1631 | dnsmasq just supplies the PXE information and another DHCP | |
1632 | server does address allocation, is also allowed. See the | |
1633 | --pxe-prompt and --pxe-service keywords. Thanks to | |
1634 | Alkis Georgopoulos for the suggestion and Guilherme Moro | |
1635 | and Michael Brown for assistance. | |
1636 | ||
1637 | Improvements to DHCP logging. Thanks to Tom Metro for | |
1638 | useful suggestions. | |
3be34541 | 1639 | |
7622fc06 SK |
1640 | Add ability to build dnsmasq without DHCP support. To do |
1641 | this, edit src/config.h or build with | |
1642 | "make COPTS=-DNO_DHCP". Thanks to Mahavir Jain for the patch. | |
36717eee | 1643 | |
7622fc06 SK |
1644 | Added --test command-line switch - syntax check |
1645 | configuration files only. | |
36717eee | 1646 | |
7622fc06 | 1647 | Updated French translation. Thanks to Gildas Le Nadan. |

3d8df260 | 1649 | |
7622fc06 SK |
1650 | version 2.47 |
1651 | Updated French translation. Thanks to Gildas Le Nadan. | |
3d8df260 | 1652 | |
7622fc06 SK |
1653 | Fixed interface enumeration code to work on NetBSD |
1654 | 5.0. Thanks to Roy Marples for the patch. | |
3d8df260 | 1655 | |
7622fc06 SK |
1656 | Updated config.h to use the same location for the lease |
1657 | file on NetBSD as the other *BSD variants. Also allow | |
1658 | LEASEFILE and CONFFILE symbols to be overriden in CFLAGS. | |

1660 | Handle duplicate address detection on IPv6 more |
1661 | intelligently. In IPv6, an interface can have an address | |
1662 | which is not usable, because it is still undergoing DAD | |
1663 | (such addresses are marked "tentative"). Attempting to | |
1664 | bind to an address in this state returns an error, | |
1665 | EADDRNOTAVAIL. Previously, on getting such an error, | |
1666 | dnsmasq would silently abandon the address, and never | |
1667 | listen on it. Now, it retries once per second for 20 | |
1668 | seconds before generating a fatal error. 20 seconds should | |
1669 | be long enough for any DAD process to complete, but can be | |
1670 | adjusted in src/config.h if necessary. Thanks to Martin | |
1671 | Krafft for the bug report. | |

1679 | Support arbitrarily encapsulated DHCP options, suggestion |
1680 | and initial patch from Samium Gromoff. This is useful for | |
1681 | (eg) gPXE, which expect all its private options to be | |
1682 | encapsulated inside a single option 175. So, eg, | |
b8187c80 | 1683 | |
7622fc06 SK |
1684 | dhcp-option = encap:175, 190, "iscsi-client0" |
1685 | dhcp-option = encap:175, 191, "iscsi-client0-secret" | |
b8187c80 | 1686 | |
7622fc06 | 1687 | will provide iSCSI parameters to gPXE. |

7622fc06 SK |
1689 | Enhance --dhcp-match to allow testing of the contents of a |
1690 | client-sent option, as well as its presence. This | |
1691 | application in mind for this is RFC 4578 | |
1692 | client-architecture specifiers, but it's generally useful. | |
1693 | Joey Korkames suggested the enhancement. | |

1706 | Reply to DHCPINFORM requests even when the supplied ciaddr |
1707 | doesn't fall in any dhcp-range. In this case it's not | |
1708 | possible to supply a complete configuration, but | |
1709 | individually-configured options (eg PAC) may be useful. | |

1711 | Allow the source address of an alias to be a range: |
1712 | --alias=192.168.0.0,10.0.0.0,255.255.255.0 maps the whole | |
1713 | subnet 192.168.0.0->192.168.0.255 to 10.0.0.0->10.0.0.255, | |
1714 | as before. | |
1715 | --alias=192.168.0.10-192.168.0.40,10.0.0.0,255.255.255.0 | |
1716 | maps only the 192.168.0.10->192.168.0.40 region. Thanks to | |

1719 | Don't dynamically allocate DHCP addresses which may break |
1720 | Windows. Addresses which end in .255 or .0 are broken in | |
1721 | Windows even when using supernetting. | |
1722 | --dhcp-range=192.168.0.1,192.168.1.254,255,255,254.0 means | |
1723 | 192.168.0.255 is a valid IP address, but not for Windows. | |
1724 | See Microsoft KB281579. We therefore no longer allocate | |
1725 | these addresses to avoid hard-to-diagnose problems. | |

1729 | Delete the PID-file when dnsmasq shuts down. Note that by |
1730 | this time, dnsmasq is normally not running as root, so | |
1731 | this will fail if the PID-file is stored in a root-owned | |
1732 | directory; such failure is silently ignored. To take | |
1733 | advantage of this feature, the PID-file must be stored in a | |
1734 | directory owned and write-able by the user running | |
1735 | dnsmasq. | |

1743 | Remove ISC-leasefile reading code. This has been |
1744 | deprecated for a long time, and last time I removed it, it | |
1745 | ended up going back by request of one user. This time, | |
1746 | it's gone for good; otherwise it would need to be | |
1747 | re-worked to support multiple domains (see below). | |
5aabfc78 | 1748 | |
7622fc06 SK |
1749 | Support DHCP clients in multiple DNS domains. This is a |
1750 | long-standing request. Clients are assigned to a domain | |
1751 | based in their IP address. | |
5aabfc78 | 1752 | |
7622fc06 SK |
1753 | Add --dhcp-fqdn flag, which changes behaviour if DNS names |
1754 | assigned to DHCP clients. When this is set, there must be | |
1755 | a domain associated with each client, and only | |
1756 | fully-qualified domain names are added to the DNS. The | |
1757 | advantage is that the only the FQDN needs to be unique, | |
1758 | so that two or more DHCP clients can share a hostname, as | |
1759 | long as they are in different domains. | |
5aabfc78 | 1760 | |
7622fc06 SK |
1761 | Set environment variable DNSMASQ_DOMAIN when invoking |
1762 | lease-change script. This may be useful information to | |
1763 | have now that it's variable. | |

7622fc06 SK |
1765 | Tighten up data-checking code for DNS packet |
1766 | handling. Thanks to Steve Dodd who found certain illegal | |
1767 | packets which could crash dnsmasq. No memory overwrite was | |
1768 | possible, so this is not a security issue beyond the DoS | |
1769 | potential. | |
824af85b | 1770 | |
7622fc06 SK |
1771 | Update example config dhcp option 47, the previous |
1772 | suggestion generated an illegal, zero-length, | |
1773 | option. Thanks to Matthias Andree for finding this. | |

824af85b | 1786 | |
7622fc06 SK |
1787 | Allow for more that one MAC address in a dhcp-host |
1788 | line. This configuration tells dnsmasq that it's OK to | |
1789 | abandon a DHCP lease of the fixed address to one MAC | |
1790 | address, if another MAC address in the dhcp-host statement | |
1791 | asks for an address. This is useful to give a fixed | |
1792 | address to a host which has two network interfaces | |
1793 | (say, a laptop with wired and wireless interfaces.) | |
1794 | It's very important to ensure that only one interface | |
1795 | at a time is up, since dnsmasq abandons the first lease | |
1796 | and re-uses the address before the leased time has | |
1797 | elapsed. John Gray suggested this. | |
824af85b | 1798 | |
7622fc06 SK |
1799 | Tweak the response to a DHCP request packet with a wrong |
1800 | server-id when --dhcp-authoritative is set; dnsmasq now | |
1801 | returns a DHCPNAK, rather than silently ignoring the | |
1802 | packet. Thanks to Chris Marget for spotting this | |
1803 | improvement. | |
824af85b | 1804 | |
7622fc06 SK |
1805 | Add --cname option. This provides a limited alias |
1806 | function, usable for DHCP names. Thanks to AJ Weber for | |
1807 | suggestions on this. | |

9e038946 | 1834 | |
7622fc06 SK |

1851 | version 2.43 | |
1852 | Updated Polish translation. Thanks to Jan Psota. | |
1853 | ||
1854 | Flag errors when configuration options are repeated | |
1855 | illegally. | |
1856 | ||
1857 | Further tweaks for GNU/kFreeBSD | |
1858 | ||
1859 | Add --no-wrap to msgmerge call - provides nicer .po file | |
1860 | format. | |
1861 | ||
1862 | Honour lease-time spec in dhcp-host lines even for | |
1863 | BOOTP. The user is assumed to known what they are doing in | |
1864 | this case. (Hosts without the time spec still get infinite | |
1865 | leases for BOOTP, over-riding the default in the | |
1866 | dhcp-range.) Thanks to Peter Katzmann for uncovering this. | |
1867 | ||
1868 | Fix problem matching relay-agent ids. Thanks to Michael | |
1869 | Rack for the bug report. | |
1870 | ||
1871 | Add --naptr-record option. Suggestion from Johan | |
1872 | Bergquist. | |
1873 | ||
1874 | Implement RFC 5107 server-id-override DHCP relay agent | |
1875 | option. | |
1876 | ||
1877 | Apply patches from Stefan Kruger for compilation on | |
1878 | Solaris 10 under Sun studio. | |
1879 | ||
1880 | Yet more tweaking of Linux capability code, to suppress | |
1881 | pointless wingeing from kernel 2.6.25 and above. | |
1882 | ||
1883 | Improve error checking during startup. Previously, some | |
1884 | errors which occurred during startup would be worked | |
1885 | around, with dnsmasq still starting up. Some were logged, | |
1886 | some silent. Now, they all cause a fatal error and dnsmasq | |
1887 | terminates with a non-zero exit code. The errors are those | |
1888 | associated with changing uid and gid, setting process | |
1889 | capabilities and writing the pidfile. Thanks to Uwe | |
1890 | Gansert and the Suse security team for pointing out | |
1891 | this improvement, and Bill Reimers for good implementation | |
1892 | suggestions. | |
1893 | ||
1894 | Provide NO_LARGEFILE compile option to switch off largefile | |
1895 | support when compiling against versions of uclibc which | |
1896 | don't support it. Thanks to Stephane Billiart for the patch. | |
1897 | ||
1898 | Implement random source ports for interactions with | |
1899 | upstream nameservers. New spoofing attacks have been found | |
1900 | against nameservers which do not do this, though it is not | |
1901 | clear if dnsmasq is vulnerable, since to doesn't implement | |
1902 | recursion. By default dnsmasq will now use a different | |
1903 | source port (and socket) for each query it sends | |
1904 | upstream. This behaviour can suppressed using the | |
1905 | --query-port option, and the old default behaviour | |
1906 | restored using --query-port=0. Explicit source-port | |
1907 | specifications in --server configs are still honoured. | |
1908 | ||
1909 | Replace the random number generator, for better | |
1910 | security. On most BSD systems, dnsmasq uses the | |
1911 | arc4random() RNG, which is secure, but on other platforms, | |
1912 | it relied on the C-library RNG, which may be | |
1913 | guessable and therefore allow spoofing. This release | |
1914 | replaces the libc RNG with the SURF RNG, from Daniel | |
1915 | J. Berstein's DJBDNS package. | |
1916 | ||
1917 | Don't attempt to change user or group or set capabilities | |
1918 | if dnsmasq is run as a non-root user. Without this, the | |
1919 | change from soft to hard errors when these fail causes | |
1920 | problems for non-root daemons listening on high | |
1921 | ports. Thanks to Patrick McLean for spotting this. | |
1922 | ||
1923 | Updated French translation. Thanks to Gildas Le Nadan. | |
