2 Fix reversion in 2.73 where --conf-file would attempt to
3 read the default file, rather than no file.
7 Fix crash at startup when an empty suffix is supplied to
8 --conf-dir, also trivial memory leak. Thanks to
9 Tomas Hozza for spotting this.
11 Remove floor of 4096 on advertised EDNS0 packet size when
12 DNSSEC in use, the original rationale for this has long gone.
13 Thanks to Anders Kaseorg for spotting this.
15 Use inotify for checking on updates to /etc/resolv.conf and
16 friends under Linux. This fixes race conditions when the files are
17 updated rapidly and saves CPU by noy polling. To build
18 a binary that runs on old Linux kernels without inotify,
19 use make COPTS=-DNO_INOTIFY
21 Fix breakage of --domain=<domain>,<subnet>,local - only reverse
22 queries were intercepted. THis appears to have been broken
23 since 2.69. Thanks to Josh Stone for finding the bug.
25 Eliminate IPv6 privacy addresses and deprecated addresses from
26 the answers given by --interface-name. Note that reverse queries
27 (ie looking for names, given addresses) are not affected.
28 Thanks to Michael Gorbach for the suggestion.
30 Fix crash in DNSSEC code with long RRs. Thanks to Marco Davids
33 Add --ignore-address option. Ignore replies to A-record
34 queries which include the specified address. No error is
35 generated, dnsmasq simply continues to listen for another
36 reply. This is useful to defeat blocking strategies which
37 rely on quickly supplying a forged answer to a DNS
38 request for certain domains, before the correct answer can
39 arrive. Thanks to Glen Huang for the patch.
41 Revisit the part of DNSSEC validation which determines if an
42 unsigned answer is legit, or is in some part of the DNS
43 tree which should be signed. Dnsmasq now works from the
44 DNS root downward looking for the limit of signed
45 delegations, rather than working bottom up. This is
46 both more correct, and less likely to trip over broken
47 nameservers in the unsigned parts of the DNS tree
48 which don't respond well to DNSSEC queries.
50 Add --log-queries=extra option, which makes logs easier
51 to search automatically.
53 Add --min-cache-ttl option. I've resisted this for a long
54 time, on the grounds that disbelieving TTLs is never a
55 good idea, but I've been persuaded that there are
56 sometimes reasons to do it. (Step forward, GFW).
57 To avoid misuse, there's a hard limit on the TTL
58 floor of one hour. Thansk to RinSatsuki for the patch.
60 Cope with multiple interfaces with the same link-local
61 address. (IPv6 addresses are scoped, so this is allowed.)
62 Thanks to Cory Benfield for help with this.
64 Add --dhcp-hostsdir. This allows addition of new host
65 configurations to a running dnsmasq instance much more
66 cheaply than having dnsmasq re-read all its existing
67 configuration each time.
69 Don't reply to DHCPv6 SOLICIT messages if we're not
70 configured to do stateful DHCPv6. Thanks to Win King Wan
73 Fix broken DNSSEC validation of ECDSA signatures.
75 Add --dnssec-timestamp option, which provides an automatic
76 way to detect when the system time becomes valid after
77 boot on systems without an RTC, whilst allowing DNS
78 queries before the clock is valid so that NTP can run.
79 Thanks to Kevin Darbyshire-Bryant for developing this idea.
81 Add --tftp-no-fail option. Thanks to Stefan Tomanek for
84 Fix crash caused by looking up servers.bind, CHAOS text
85 record, when more than about five --servers= lines are
86 in the dnsmasq config. This causes memory corruption
87 which causes a crash later. Thanks to Matt Coddington for
88 sterling work chasing this down.
90 Fix crash on receipt of certain malformed DNS requests.
91 Thanks to Nick Sampanis for spotting the problem.
92 Note that this is could allow the dnsmasq process's
93 memory to be read by an attacker under certain
94 circumstances, so it has a CVE, CVE-2015-3294
96 Fix crash in authoritative DNS code, if a .arpa zone
97 is declared as authoritative, and then a PTR query which
98 is not to be treated as authoritative arrived. Normally,
99 directly declaring .arpa zone as authoritative is not
100 done, so this crash wouldn't be seen. Instead the
101 relevant .arpa zone should be specified as a subnet
102 in the auth-zone declaration. Thanks to Johnny S. Lee
103 for the bugreport and initial patch.
105 Fix authoritative DNS code to correctly reply to NS
106 and SOA queries for .arpa zones for which we are
107 declared authoritative by means of a subnet in auth-zone.
108 Previously we provided correct answers to PTR queries
109 in such zones (including NS and SOA) but not direct
110 NS and SOA queries. Thanks to Johnny S. Lee for
111 pointing out the problem.
113 Fix logging of DHCPREPLY which should be suppressed
114 by quiet-dhcp6. Thanks to J. Pablo Abonia for
115 spotting the problem.
117 Try and handle net connections with broken fragmentation
118 that lose large UDP packets. If a server times out,
119 reduce the maximum UDP packet size field in the EDNS0
120 header to 1280 bytes. If it then answers, make that
123 Check IPv4-mapped IPv6 addresses when --stop-rebind
124 is active. Thanks to Jordan Milne for spotting this.
126 Allow DHCPv4 options T1 and T2 to be set using --dhcp-option.
127 Thanks to Kevin Benton for patches and work on this.
129 Fix code for DHCPCONFIRM DHCPv6 messages to confirm addresses
130 in the correct subnet, even of not in dynamic address
131 allocation range. Thanks to Steve Hirsch for spotting
134 Add AddDhcpLease and DeleteDhcpLease DBus methods. Thanks
135 to Nicolas Cavallari for the patch.
137 Allow configuration of router advertisements without the
138 "on-link" bit set. Thanks to Neil Jerram for the patch.
140 Extend --bridge-interface to DHCPv6 and router
141 advertisements. Thanks to Neil Jerram for the patch.
145 Add ra-advrouter mode, for RFC-3775 mobile IPv6 support.
147 Add support for "ipsets" in *BSD, using pf. Thanks to
148 Sven Falempim for the patch.
150 Fix race condition which could lock up dnsmasq when an
151 interface goes down and up rapidly. Thanks to Conrad
152 Kostecki for helping to chase this down.
154 Add DBus methods SetFilterWin2KOption and SetBogusPrivOption
155 Thanks to the Smoothwall project for the patch.
157 Fix failure to build against Nettle-3.0. Thanks to Steven
158 Barth for spotting this and finding the fix.
160 When assigning existing DHCP leases to intefaces by comparing
161 networks, handle the case that two or more interfaces have the
162 same network part, but different prefix lengths (favour the
163 longer prefix length.) Thanks to Lung-Pin Chang for the
166 Add a mode which detects and removes DNS forwarding loops, ie
167 a query sent to an upstream server returns as a new query to
168 dnsmasq, and would therefore be forwarded again, resulting in
169 a query which loops many times before being dropped. Upstream
170 servers which loop back are disabled and this event is logged.
171 Thanks to Smoothwall for their sponsorship of this feature.
173 Extend --conf-dir to allow filtering of files. So
174 --conf-dir=/etc/dnsmasq.d,\*.conf
175 will load all the files in /etc/dnsmasq.d which end in .conf
177 Fix bug when resulted in NXDOMAIN answers instead of NODATA in
180 Fix bug which caused dnsmasq to become unresponsive if it
181 failed to send packets due to a network interface disappearing.
182 Thanks to Niels Peen for spotting this.
184 Fix problem with --local-service option on big-endian platforms
185 Thanks to Richard Genoud for the patch.
189 Subtle change to error handling to help DNSSEC validation
190 when servers fail to provide NODATA answers for
191 non-existent DS records.
193 Tweak code which removes DNSSEC records from answers when
194 not required. Fixes broken answers when additional section
195 has real records in it. Thanks to Marco Davids for the bug
198 Fix DNSSEC validation of ANY queries. Thanks to Marco Davids
199 for spotting that too.
201 Fix total DNS failure and 100% CPU use if cachesize set to zero,
202 regression introduced in 2.69. Thanks to James Hunt and
203 the Ubuntu crowd for assistance in fixing this.
207 Fix crash, introduced in 2.69, on TCP request when dnsmasq
208 compiled with DNSSEC support, but running without DNSSEC
209 enabled. Thanks to Manish Sing for spotting that one.
211 Fix regression which broke ipset functionality. Thanks to
212 Wang Jian for the bug report.
216 Implement dynamic interface discovery on *BSD. This allows
217 the contructor: syntax to be used in dhcp-range for DHCPv6
218 on the BSD platform. Thanks to Matthias Andree for
219 valuable research on how to implement this.
221 Fix infinite loop associated with some --bogus-nxdomain
222 configs. Thanks fogobogo for the bug report.
224 Fix missing RA RDNS option with configuration like
225 --dhcp-option=option6:23,[::] Thanks to Tsachi Kimeldorfer
226 for spotting the problem.
228 Add [fd00::] and [fe80::] as special addresses in DHCPv6
229 options, analogous to [::]. [fd00::] is replaced with the
230 actual ULA of the interface on the machine running
231 dnsmasq, [fe80::] with the link-local address.
232 Thanks to Tsachi Kimeldorfer for championing this.
234 DNSSEC validation and caching. Dnsmasq needs to be
235 compiled with this enabled, with
237 make dnsmasq COPTS=-DHAVE_DNSSEC
239 this add dependencies on the nettle crypto library and the
240 gmp maths library. It's possible to have these linked
243 make dnsmasq COPTS='-DHAVE_DNSSEC -DHAVE_DNSSEC_STATIC'
245 which bloats the dnsmasq binary, but saves the size of
246 the shared libraries which are much bigger.
248 To enable, DNSSEC, you will need a set of
249 trust-anchors. Now that the TLDs are signed, this can be
250 the keys for the root zone, and for convenience they are
251 included in trust-anchors.conf in the dnsmasq
252 distribution. You should of course check that these are
253 legitimate and up-to-date. So, adding
255 conf-file=/path/to/trust-anchors.conf
258 to your config is all thats needed to get things
259 working. The upstream nameservers have to be DNSSEC-capable
260 too, of course. Many ISP nameservers aren't, but the
261 Google public nameservers (8.8.8.8 and 8.8.4.4) are.
262 When DNSSEC is configured, dnsmasq validates any queries
263 for domains which are signed. Query results which are
264 bogus are replaced with SERVFAIL replies, and results
265 which are correctly signed have the AD bit set. In
266 addition, and just as importantly, dnsmasq supplies
267 correct DNSSEC information to clients which are doing
268 their own validation, and caches DNSKEY, DS and RRSIG
269 records, which significantly improve the performance of
270 downstream validators. Setting --log-queries will show
273 If a domain is returned from an upstream nameserver without
274 DNSSEC signature, dnsmasq by default trusts this. This
275 means that for unsigned zone (still the majority) there
276 is effectively no cost for having DNSSEC enabled. Of course
277 this allows an attacker to replace a signed record with a
278 false unsigned record. This is addressed by the
279 --dnssec-check-unsigned flag, which instructs dnsmasq
280 to prove that an unsigned record is legitimate, by finding
281 a secure proof that the zone containing the record is not
282 signed. Doing this has costs (typically one or two extra
283 upstream queries). It also has a nasty failure mode if
284 dnsmasq's upstream nameservers are not DNSSEC capable.
285 Without --dnssec-check-unsigned using such an upstream
286 server will simply result in not queries being validated;
287 with --dnssec-check-unsigned enabled and a
288 DNSSEC-ignorant upstream server, _all_ queries will fail.
290 Note that DNSSEC requires that the local time is valid and
291 accurate, if not then DNSSEC validation will fail. NTP
292 should be running. This presents a problem for routers
293 without a battery-backed clock. To set the time needs NTP
294 to do DNS lookups, but lookups will fail until NTP has run.
295 To address this, there's a flag, --dnssec-no-timecheck
296 which disables the time checks (only) in DNSSEC. When dnsmasq
297 is started and the clock is not synced, this flag should
298 be used. As soon as the clock is synced, SIGHUP dnsmasq.
299 The SIGHUP clears the cache of partially-validated data and
300 resets the no-timecheck flag, so that all DNSSEC checks
301 henceforward will be complete.
303 The development of DNSSEC in dnsmasq was started by
304 Giovanni Bajo, to whom huge thanks are owed. It has been
305 supported by Comcast, whose techfund grant has allowed for
306 an invaluable period of full-time work to get it to
309 Add --rev-server. Thanks to Dave Taht for suggesting this.
311 Add --servers-file. Allows dynamic update of upstream servers
312 full access to configuration.
314 Add --local-service. Accept DNS queries only from hosts
315 whose address is on a local subnet, ie a subnet for which
316 an interface exists on the server. This option
317 only has effect if there are no --interface --except-interface,
318 --listen-address or --auth-server options. It is intended
319 to be set as a default on installation, to allow
320 unconfigured installations to be useful but also safe from
321 being used for DNS amplification attacks.
323 Fix crashes in cache_get_cname_target() when dangling CNAMEs
324 encountered. Thanks to Andy and the rt-n56u project for
325 find this and helping to chase it down.
327 Fix wrong RCODE in authoritative DNS replies to PTR queries. The
328 correct answer was included, but the RCODE was set to NXDOMAIN.
329 Thanks to Craig McQueen for spotting this.
331 Make statistics available as DNS queries in the .bind TLD as
332 well as logging them.
336 Use random addresses for DHCPv6 temporary address
337 allocations, instead of algorithmically determined stable
340 Fix bug which meant that the DHCPv6 DUID was not available
341 in DHCP script runs during the lifetime of the dnsmasq
342 process which created the DUID de-novo. Once the DUID was
343 created and stored in the lease file and dnsmasq
344 restarted, this bug disappeared.
346 Fix bug introduced in 2.67 which could result in erroneous
347 NXDOMAIN returns to CNAME queries.
349 Fix build failures on MacOS X and openBSD.
351 Allow subnet specifications in --auth-zone to be interface
352 names as well as address literals. This makes it possible
353 to configure authoritative DNS when local address ranges
354 are dynamic and works much better than the previous
355 work-around which exempted contructed DHCP ranges from the
356 IP address filtering. As a consequence, that work-around
357 is removed. Under certain circumstances, this change wil
358 break existing configuration: if you're relying on the
359 contructed-range exception, you need to change --auth-zone
360 to specify the same interface as is used to construct your
361 DHCP ranges, probably with a trailing "/6" like this:
362 --auth-zone=example.com,eth0/6 to limit the addresses to
363 IPv6 addresses of eth0.
365 Fix problems when advertising deleted IPv6 prefixes. If
366 the prefix is deleted (rather than replaced), it doesn't
367 get advertised with zero preferred time. Thanks to Tsachi
370 Fix segfault with some locally configured CNAMEs. Thanks
371 to Andrew Childs for spotting the problem.
373 Fix memory leak on re-reading /etc/hosts and friends,
376 Check the arrival interface of incoming DNS and TFTP
377 requests via IPv6, even in --bind-interfaces mode. This
378 isn't possible for IPv4 and can generate scary warnings,
379 but as it's always possible for IPv6 (the API always
380 exists) then we should do it always.
382 Tweak the rules on prefix-lengths in --dhcp-range for
383 IPv6. The new rule is that the specified prefix length
384 must be larger than or equal to the prefix length of the
385 corresponding address on the local interface.
389 Fix crash if upstream server returns SERVFAIL when
390 --conntrack in use. Thanks to Giacomo Tazzari for finding
391 this and supplying the patch.
393 Repair regression in 2.64. That release stopped sending
394 lease-time information in the reply to DHCPINFORM
395 requests, on the correct grounds that it was a standards
396 violation. However, this broke the dnsmasq-specific
397 dhcp_lease_time utility. Now, DHCPINFORM returns
398 lease-time only if it's specifically requested
399 (maintaining standards) and the dhcp_lease_time utility
400 has been taught to ask for it (restoring functionality).
402 Fix --dhcp-match, --dhcp-vendorclass and --dhcp-userclass
403 to work with BOOTP and well as DHCP. Thanks to Peter
404 Korsgaard for spotting the problem.
406 Add --synth-domain. Thanks to Vishvananda Ishaya for
409 Fix failure to compile ipset.c if old kernel headers are
410 in use. Thanks to Eugene Rudoy for pointing this out.
412 Handle IPv4 interface-address labels in Linux. These are
413 often used to emulate the old IP-alias addresses. Before,
414 using --interface=eth0 would service all the addresses of
415 eth0, including ones configured as aliases, which appear
416 in ifconfig as eth0:0. Now, only addresses with the label
417 eth0 are active. This is not backwards compatible: if you
418 want to continue to bind the aliases too, you need to add
419 eg. --interface=eth0:0 to the config.
421 Fix "failed to set SO_BINDTODEVICE on DHCP socket: Socket
422 operation on non-socket" error on startup with
423 configurations which have exactly one --interface option
424 and do RA but _not_ DHCPv6. Thanks to Trever Adams for the
427 Generalise --interface-name to cope with IPv6 addresses
428 and multiple addresses per interface per address family.
430 Fix option parsing for --dhcp-host, which was generating a
431 spurious error when all seven possible items were
432 included. Thanks to Zhiqiang Wang for the bug report.
434 Remove restriction on prefix-length in --auth-zone. Thanks
435 to Toke Hoiland-Jorgensen for suggesting this.
437 Log when the maximum number of concurrent DNS queries is
438 reached. Thanks to Marcelo Salhab Brogliato for the patch.
440 If wildcards are used in --interface, don't assume that
441 there will only ever be one available interface for DHCP
442 just because there is one at start-up. More may appear, so
443 we can't use SO_BINDTODEVICE. Thanks to Natrio for the bug
446 Increase timeout/number of retries in TFTP to accomodate
447 AudioCodes Voice Gateways doing streaming writes to flash.
448 Thanks to Damian Kaczkowski for spotting the problem.
450 Fix crash with empty DHCP string options when adding zero
451 terminator. Thanks to Patrick McLean for the bug report.
453 Allow hostnames to start with a number, as allowed in
454 RFC-1123. Thanks to Kyle Mestery for the patch.
456 Fixes to DHCP FQDN option handling: don't terminate FQDN
457 if domain not known and allow a FQDN option with blank
458 name to request that a FQDN option is returned in the
459 reply. Thanks to Roy Marples for the patch.
461 Make --clear-on-reload apply to setting upstream servers
464 When the address which triggered the construction of an
465 advertised IPv6 prefix disappears, continue to advertise
466 the prefix for up to 2 hours, with the preferred lifetime
467 set to zero. This satisfies RFC 6204 4.3 L-13 and makes
468 things work better if a prefix disappears without being
469 deprecated first. Thanks to Uwe Schindler for persuasively
472 Fix MAC address enumeration on *BSD. Thanks to Brad Smith
475 Support RFC-4242 information-refresh-time options in the
476 reply to DHCPv6 information-request. The lease time of the
477 smallest valid dhcp-range is sent. Thanks to Uwe Schindler
480 Make --listen-address higher priority than --except-interface
481 in all circumstances. Thanks to Thomas Hood for the bugreport.
483 Provide independent control over which interfaces get TFTP
484 service. If enable-tftp is given a list of interfaces, then TFTP
485 is provided on those. Without the list, the previous behaviour
486 (provide TFTP to the same interfaces we provide DHCP to)
487 is retained. Thanks to Lonnie Abelbeck for the suggestion.
489 Add --dhcp-relay config option. Many thanks to vtsl.net
490 for sponsoring this development.
492 Fix crash with empty tag: in --dhcp-range. Thanks to
493 Kaspar Schleiser for the bug report.
495 Add "baseline" and "bloatcheck" makefile targets, for
496 revealing size changes during development. Thanks to
497 Vladislav Grishenko for the patch.
499 Cope with DHCPv6 clients which send REQUESTs without
500 address options - treat them as SOLICIT with rapid commit.
502 Support identification of clients by MAC address in
503 DHCPv6. When using a relay, the relay must support RFC
504 6939 for this to work. It always works for directly
505 connected clients. Thanks to Vladislav Grishenko
506 for prompting this feature.
508 Remove the rule for constructed DHCP ranges that the local
509 address must be either the first or last address in the
510 range. This was originally to avoid SLAAC addresses, but
511 we now explicitly autoconfig and privacy addresses instead.
513 Update Polish translation. Thanks to Jan Psota.
515 Fix problem in DHCPv6 vendorclass/userclass matching
516 code. Thanks to Tanguy Bouzeloc for the patch.
518 Update Spanish transalation. Thanks to Vicente Soriano.
520 Add --ra-param option. Thanks to Vladislav Grishenko for
523 Add --add-subnet configuration, to tell upstream DNS
524 servers where the original client is. Thanks to DNSthingy
525 for sponsoring this feature.
527 Add --quiet-dhcp, --quiet-dhcp6 and --quiet-ra. Thanks to
528 Kevin Darbyshire-Bryant for the initial patch.
530 Allow A/AAAA records created by --interface-name to be the
531 target of --cname. Thanks to Hadmut Danisch for the
534 Avoid treating a --dhcp-host which has an IPv6 address
535 as eligable for use with DHCPv4 on the grounds that it has
536 no address, and vice-versa. Thanks to Yury Konovalov for
537 spotting the problem.
539 Do a better job caching dangling CNAMEs. Thanks to Yves
540 Dorfsman for spotting the problem.
544 Add the ability to act as an authoritative DNS
545 server. Dnsmasq can now answer queries from the wider 'net
546 with local data, as long as the correct NS records are set
547 up. Only local data is provided, to avoid creating an open
548 DNS relay. Zone transfer is supported, to allow secondary
549 servers to be configured.
551 Add "constructed DHCP ranges" for DHCPv6. This is intended
552 for IPv6 routers which get prefixes dynamically via prefix
553 delegation. With suitable configuration, stateful DHCPv6
554 and RA can happen automatically as prefixes are delegated
555 and then deprecated, without having to re-write the
556 dnsmasq configuration file or restart the daemon. Thanks to
557 Steven Barth for extensive testing and development work on
560 Fix crash on startup on Solaris 11. Regression probably
561 introduced in 2.61. Thanks to Geoff Johnstone for the
564 Add code to make behaviour for TCP DNS requests that same
565 as for UDP requests, when a request arrives for an allowed
566 address, but via a banned interface. This change is only
567 active on Linux, since the relevant API is missing (AFAIK)
568 on other platforms. Many thanks to Tomas Hozza for
569 spotting the problem, and doing invaluable discovery of
570 the obscure and undocumented API required for the solution.
572 Don't send the default DHCP option advertising dnsmasq as
573 the local DNS server if dnsmasq is configured to not act
574 as DNS server, or it's configured to a non-standard port.
576 Add DNSMASQ_CIRCUIT_ID, DNSMASQ_SUBCRIBER_ID,
577 DNSMASQ_REMOTE_ID variables to the environment of the
578 lease-change script (and the corresponding Lua). These hold
579 information inserted into the DHCP request by a DHCP relay
580 agent. Thanks to Lakefield Communications for providing a
581 bounty for this addition.
583 Fixed crash, introduced in 2.64, whilst handling DHCPv6
584 information-requests with some common configurations.
585 Thanks to Robert M. Albrecht for the bug report and
588 Add --ipset option. Thanks to Jason A. Donenfeld for the
591 Don't erroneously reject some option names in --dhcp-match
592 options. Thanks to Benedikt Hochstrasser for the bug report.
594 Allow a trailing '*' wildcard in all interface-name
595 configurations. Thanks to Christian Parpart for the patch.
597 Handle the situation where libc headers define
598 SO_REUSEPORT, but the kernel in use doesn't, to cope with
599 the introduction of this option to Linux. Thanks to Rich
600 Felker for the bug report.
602 Update Polish translation. Thanks to Jan Psota.
604 Fix crash if the configured DHCP lease limit is
605 reached. Regression occurred in 2.61. Thanks to Tsachi for
608 Update the French translation. Thanks to Gildas le Nadan.
612 Fix regression which broke forwarding of queries sent via
613 TCP which are not for A and AAAA and which were directed to
614 non-default servers. Thanks to Niax for the bug report.
616 Fix failure to build with DHCP support excluded. Thanks to
617 Gustavo Zacarias for the patch.
619 Fix nasty regression in 2.64 which completely broke cacheing.
623 Handle DHCP FQDN options with all flag bits zero and
624 --dhcp-client-update set. Thanks to Bernd Krumbroeck for
625 spotting the problem.
627 Finesse the check for /etc/hosts names which conflict with
628 DHCP names. Previously a name/address pair in /etc/hosts
629 which didn't match the name/address of a DHCP lease would
630 generate a warning. Now that only happesn if there is not
631 also a match. This allows multiple addresses for a name in
632 /etc/hosts with one of them assigned via DHCP.
634 Fix broken vendor-option processing for BOOTP. Thanks to
635 Hans-Joachim Baader for the bug report.
637 Don't report spurious netlink errors, regression in
638 2.63. Thanks to Vladislav Grishenko for the patch.
640 Flag DHCP or DHCPv6 in starup logging. Thanks to
641 Vladislav Grishenko for the patch.
643 Add SetServersEx method in DBus interface. Thanks to Dan
644 Williams for the patch.
646 Add SetDomainServers method in DBus interface. Thanks to
647 Roy Marples for the patch.
649 Fix build with later Lua libraries. Thansk to Cristian
650 Rodriguez for the patch.
652 Add --max-cache-ttl option. Thanks to Dennis Kaarsemaker
655 Fix breakage of --host-record parsing, resulting in
656 infinte loop at startup. Regression in 2.63. Thanks to
657 Haim Gelfenbeyn for spotting this.
659 Set SO_REUSEADDRESS and SO_V6ONLY options on the DHCPv6
660 socket, this allows multiple instances of dnsmasq on a
661 single machine, in the same way as for DHCPv4. Thanks to
662 Gene Czarcinski and Vladislav Grishenko for work on this.
664 Fix DHCPv6 to do access control correctly when it's
665 configured with --listen-address. Thanks to
666 Gene Czarcinski for sorting this out.
668 Add a "wildcard" dhcp-range which works for any IPv6
669 subnet, --dhcp-range=::,static Useful for Stateless
670 DHCPv6. Thanks to Vladislav Grishenko for the patch.
672 Don't include lease-time in DHCPACK replies to DHCPINFORM
673 queries, since RFC-2131 says we shouldn't. Thanks to
674 Wouter Ibens for pointing this out.
676 Makefile tweak to do dependency checking on header files.
677 Thanks to Johan Peeters for the patch.
679 Check interface for outgoing unsolicited router
680 advertisements, rather than relying on interface address
681 configuration. Thanks to Gene Czarinski for the patch.
683 Handle better attempts to transmit on interfaces which are
684 still doing DAD, and specifically do not just transmit
685 without setting source address and interface, since this
686 can cause very puzzling effects when a router
687 advertisement goes astray. Thanks again to Gene Czarinski.
689 Get RA timers right when there is more than one
690 dhcp-range on a subnet.
694 Do duplicate dhcp-host address check in --test mode.
696 Check that tftp-root directories are accessible before
697 start-up. Thanks to Daniel Veillard for the initial patch.
699 Allow more than one --tfp-root flag. The per-interface
700 stuff is pointless without that.
702 Add --bind-dynamic. A hybrid mode between the default and
703 --bind-interfaces which copes with dynamically created
706 A couple of fixes to the build system for Android. Thanks
707 to Metin Kaya for the patches.
709 Remove the interface:<interface> argument in --dhcp-range, and
710 the interface argument to --enable-tftp. These were a
711 still-born attempt to allow automatic isolated
712 configuration by libvirt, but have never (to my knowledge)
713 been used, had very strange semantics, and have been
714 superceded by other mechanisms.
716 Fixed bug logging filenames when duplicate dhcp-host
717 addresses are found. Thanks to John Hanks for the patch.
719 Fix regression in 2.61 which broke caching of CNAME
720 chains. Thanks to Atul Gupta for the bug report.
722 Allow the target of a --cname flag to be another --cname.
724 Teach DHCPv6 about the RFC 4242 information-refresh-time
725 option, and add parsing if the minutes, hours and days
726 format for options. Thanks to Francois-Xavier Le Bail for
729 Allow "w" (for week) as multiplier in lease times, as well
730 as seconds, minutes, hours and days. Álvaro Gámez Machado
731 spotted the ommission.
733 Update French translation. Thanks to Gildas Le Nadan.
735 Allow a DBus service name to be given with --enable-dbus
736 which overrides the default,
737 uk.org.thekelleys.dnsmasq. Thanks to Mathieu
738 Trudel-Lapierre for the patch.
740 Set the "prefix on-link" bit in Router
741 Advertisements. Thanks to Gui Iribarren for the patch.
745 Update German translation. Thanks to Conrad Kostecki.
747 Cope with router-solict packets wich don't have a valid
748 source address. Thanks to Vladislav Grishenko for the patch.
750 Fixed bug which caused missing periodic router
751 advertisements with some configurations. Thanks to
752 Vladislav Grishenko for the patch.
754 Fixed bug which broke DHCPv6/RA with prefix lengths
755 which are not divisible by 8. Thanks to Andre Coetzee
758 Fix non-response to router-solicitations when
759 router-advertisement configured, but DHCPv6 not
760 configured. Thanks to Marien Zwart for the patch.
762 Add --dns-rr, to allow arbitrary DNS resource records.
764 Fixed bug which broke RA scheduling when an interface had
765 two addresses in the same network. Thanks to Jim Bos for
766 his help nailing this.
769 Re-write interface discovery code on *BSD to use
770 getifaddrs. This is more portable, more straightforward,
771 and allows us to find the prefix length for IPv6
774 Add ra-names, ra-stateless and slaac keywords for DHCPv6.
775 Dnsmasq can now synthesise AAAA records for dual-stack
776 hosts which get IPv6 addresses via SLAAC. It is also now
777 possible to use SLAAC and stateless DHCPv6, and to
778 tell clients to use SLAAC addresses as well as DHCP ones.
779 Thanks to Dave Taht for help with this.
781 Add --dhcp-duid to allow DUID-EN uids to be used.
783 Explicity send DHCPv6 replies to the correct port, instead
784 of relying on clients to send requests with the correct
785 source address, since at least one client in the wild gets
786 this wrong. Thanks to Conrad Kostecki for help tracking
789 Send a preference value of 255 in DHCPv6 replies when
790 --dhcp-authoritative is in effect. This tells clients not
791 to wait around for other DHCP servers.
793 Better logging of DHCPv6 options.
795 Add --host-record. Thanks to Rob Zwissler for the
798 Invoke the DHCP script with action "tftp" when a TFTP file
799 transfer completes. The size of the file, address to which
800 it was sent and complete pathname are supplied. Note that
801 version 2.60 introduced some script incompatibilties
802 associated with DHCPv6, and this is a further change. To
803 be safe, scripts should ignore unknown actions, and if
804 not IPv6-aware, should exit if the environment
805 variable DNSMASQ_IAID is set. The use-case for this is
806 to track netboot/install. Suggestion from Shantanu
809 Update contrib/port-forward/dnsmasq-portforward to reflect
812 Set the environment variable DNSMASQ_LOG_DHCP when running
813 the script id --log-dhcp is in effect, so that script can
814 taylor their logging verbosity. Suggestion from Malte
817 Arrange that addresses specified with --listen-address
818 work even if there is no interface carrying the
819 address. This is chiefly useful for IPv4 loopback
820 addresses, where any address in 127.0.0.0/8 is a valid
821 loopback address, but normally only 127.0.0.1 appears on
822 the lo interface. Thanks to Mathieu Trudel-Lapierre for
823 the idea and initial patch.
825 Fix crash, introduced in 2.60, when a DHCPINFORM is
826 received from a network which has no valid dhcp-range.
827 Thanks to Stephane Glondu for the bug report.
829 Add a new DHCP lease time keyword, "deprecated" for
830 --dhcp-range. This is only valid for IPv6, and sets the
831 preffered lease time for both DHCP and RA to zero. The
832 effect is that clients can continue to use the address
833 for existing connections, but new connections will use
834 other addresses, if they exist. This makes hitless
835 renumbering at least possible.
837 Fix bug in address6_available() which caused DHCPv6 lease
838 aquisition to fail if more than one dhcp-range in use.
840 Provide RDNSS and DNSSL data in router advertisements,
841 using the settings provided for DHCP options
842 option6:domain-search and option6:dns-server.
844 Tweak logo/favicon.ico to add some transparency. Thanks to
845 SamLT for work on this.
847 Don't cache data from non-recursive nameservers, since it
848 may erroneously look like a valid CNAME to a non-exitant
849 name. Thanks to Ben Winslow for finding this.
851 Call SO_BINDTODEVICE on the DHCP socket(s) when doing DHCP
852 on exactly one interface and --bind-interfaces is set. This
853 makes the OpenStack use-case of one dnsmasq per virtual
854 interface work. This is only available on Linux; it's not
855 supported on other platforms. Thanks to Vishvananda Ishaya
856 and the OpenStack team for the suggestion.
858 Updated French translation. Thanks to Gildas Le Nadan.
860 Give correct from-cache answers to explict CNAME queries.
861 Thanks to Rob Zwissler for spotting this.
863 Add --tftp-lowercase option. Thanks to Oliver Rath for the
866 Ensure that the DBus DhcpLeaseUpdated events are generated
867 when a lease goes through INIT_REBOOT state, even if the
868 dhcp-script is not in use. Thanks to Antoaneta-Ecaterina
871 Fix failure of TFTP over IPv4 on OpenBSD platform. Thanks
872 to Brad Smith for spotting this.
876 Fix compilation problem in Mac OS X Lion. Thanks to Olaf
877 Flebbe for the patch.
879 Fix DHCP when using --listen-address with an IP address
880 which is not the primary address of an interface.
882 Add --dhcp-client-update option.
884 Add Lua integration. Dnsmasq can now execute a DHCP
885 lease-change script written in Lua. This needs to be
886 enabled at compile time by setting HAVE_LUASCRIPT in
887 src/config.h or running "make COPTS=-DHAVE_LUASCRIPT"
888 Thanks to Jan-Piet Mens for the idea and proof-of-concept
891 Tidied src/config.h to distinguish between
892 platform-dependent compile-time options which are selected
893 automatically, and builder-selectable compile time
894 options. Document the latter better, and describe how to
895 set them from the make command line.
897 Tidied up IPPROTO_IP/SOL_IP (and IPv6 equivalent)
898 confusion. IPPROTO_IP works everywhere now.
900 Set TOS on DHCP sockets, this improves things on busy
901 wireless networks. Thanks to Dave Taht for the patch.
903 Determine VERSION automatically based on git magic:
904 release tags or hash values.
906 Improve start-up speed when reading large hosts files
907 containing many distinct addresses.
909 Fix problem if dnsmasq is started without the stdin,
910 stdout and stderr file descriptors open. This can manifest
911 itself as 100% CPU use. Thanks to Chris Moore for finding
914 Fix shell-scripting bug in bld/pkg-wrapper. Thanks to
915 Mark Mitchell for the patch.
917 Allow the TFP server or boot server in --pxe-service, to
918 be a domain name instead of an IP address. This allows for
919 round-robin to multiple servers, in the same way as
920 --dhcp-boot. A good suggestion from Cristiano Cumer.
922 Support BUILDDIR variable in the Makefile. Allows builds
923 for multiple archs from the same source tree with eg.
924 make BUILDDIR=linux (relative to dnsmasq tree)
925 make BUILDDIR=/tmp/openbsd (absolute path)
926 If BUILDDIR is not set, compilation happens in the src
927 directory, as before. Suggestion from Mark Mitchell.
929 Support DHCPv6. Support is there for the sort of things
930 the existing v4 server does, including tags, options,
931 static addresses and relay support. Missing is prefix
932 delegation, which is probably not required in the dnsmasq
933 niche, and an easy way to accept prefix delegations from
934 an upstream DHCPv6 server, which is. Future plans include
935 support for DHCPv6 router option and MAC address option
936 (to make selecting clients by MAC address work like IPv4).
937 These will be added as the standards mature.
938 This code has been tested, but this is the first release,
939 so don't bet the farm on it just yet. Many thanks to all
940 testers who have got it this far.
942 Support IPv6 router advertisements. This is a
943 simple-minded implementation, aimed at providing the
944 vestigial RA needed to go alongside IPv6. Is picks up
945 configuration from the DHCPv6 conf, and should just need
946 enabling with --enable-ra.
948 Fix long-standing wrinkle with --localise-queries that
949 could result in wrong answers when DNS packets arrive
950 via an interface other than the expected one. Thanks to
951 Lorenzo Milesi and John Hanks for spotting this one.
953 Update French translation. Thanks to Gildas Le Nadan.
955 Update Polish translation. Thanks to Jan Psota.
959 Fix regression in 2.58 which caused failure to start up
960 with some combinations of dnsmasq config and IPv6 kernel
961 network config. Thanks to Brielle Bruns for the bug
964 Improve dnsmasq's behaviour when network interfaces are
965 still doing duplicate address detection (DAD). Previously,
966 dnsmasq would wait up to 20 seconds at start-up for the
967 DAD state to terminate. This is broken for bridge
968 interfaces on recent Linux kernels, which don't start DAD
969 until the bridge comes up, and so can take arbitrary
970 time. The new behaviour lets dnsmasq poll for an arbitrary
971 time whilst providing service on other interfaces. Thanks
972 to Stephen Hemminger for pointing out the problem.
976 Provide a definition of the SA_SIZE macro where it's
977 missing. Fixes build failure on openBSD.
979 Don't include a zero terminator at the end of messages
980 sent to /dev/log when /dev/log is a datagram socket.
981 Thanks to Didier Rabound for spotting the problem.
983 Add --dhcp-sequential-ip flag, to force allocation of IP
984 addresses in ascending order. Note that the default
985 pseudo-random mode is in general better but some
986 server-deployment applications need this.
988 Fix problem where a server-id of 0.0.0.0 is sent to a
989 client when a dhcp-relay is in use if a client renews a
990 lease after dnsmasq restart and before any clients on the
991 subnet get a new lease. Thanks to Mike Ruiz for assistance
992 in chasing this one down.
994 Don't return NXDOMAIN to an AAAA query if we have CNAME
995 which points to an A record only: NODATA is the correct
996 reply in this case. Thanks to Tom Fernandes for spotting
999 Relax the need to supply a netmask in --dhcp-range for
1000 networks which use a DHCP relay. Whilst this is still
1001 desireable, in the absence of a netmask dnsmasq will use
1002 a default based on the class (A, B, or C) of the address.
1003 This should at least remove a cause of mysterious failure
1004 for people using RFC1918 addresses and relays.
1006 Add support for Linux conntrack connection marking. If
1007 enabled with --conntrack, the connection mark for incoming
1008 DNS queries will be copied to the outgoing connections
1009 used to answer those queries. This allows clever firewall
1010 and accounting stuff. Only available if dnsmasq is
1011 compiled with HAVE_CONNTRACK and adds a dependency on
1012 libnetfilter-conntrack. Thanks to Ed Wildgoose for the
1013 initial idea, testing and sponsorship of this function.
1015 Provide a sane error message when someone attempts to
1016 match a tag in --dhcp-host.
1018 Tweak the behaviour of --domain-needed, to avoid problems
1019 with recursive nameservers downstream of dnsmasq. The new
1020 behaviour only stops A and AAAA queries, and returns
1021 NODATA rather than NXDOMAIN replies.
1023 Efficiency fix for very large DHCP configurations, thanks
1024 to James Gartrell and Mike Ruiz for help with this.
1026 Allow the TFTP-server address in --dhcp-boot to be a
1027 domain-name which is looked up in /etc/hosts. This can
1028 give multiple IP addresses which are used round-robin,
1029 thus doing TFTP server load-balancing. Thanks to Sushil
1030 Agrawal for the patch.
1032 When two tagged dhcp-options for a particular option
1033 number are both valid, use the one which is valid without
1034 a tag from the dhcp-range. Allows overriding of the value
1035 of a DHCP option for a particular host as well as
1036 per-network values. So
1037 --dhcp-range=set:interface1,......
1038 --dhcp-host=set:myhost,.....
1039 --dhcp-option=tag:interface1,option:nis-domain,"domain1"
1040 --dhcp-option=tag:myhost,option:nis-domain,"domain2"
1041 will set the NIS-domain to domain1 for hosts in the range, but
1042 override that to domain2 for a particular host.
1044 Fix bug which resulted in truncated files and timeouts for
1045 some TFTP transfers. The bug only occurs with netascii
1046 transfers and needs an unfortunate relationship between
1047 file size, blocksize and the number of newlines in the
1048 last block before it manifests itself. Many thanks to
1049 Alkis Georgopoulos for spotting the problem and providing
1050 a comprehensive test-case.
1052 Fix regression in TFTP server on *BSD platforms introduced
1053 in version 2.56, due to confusion with sockaddr
1054 length. Many thanks to Loic Pefferkorn for finding this.
1056 Support scope-ids in IPv6 addresses of nameservers from
1057 /etc/resolv.conf and in --server options. Eg
1058 nameserver fe80::202:a412:4512:7bbf%eth0 or
1059 server=fe80::202:a412:4512:7bbf%eth0. Thanks to
1060 Michael Stapelberg for the suggestion.
1062 Update Polish translation, thanks to Jan Psota.
1064 Update French translation. Thanks to Gildas Le Nadan.
1068 Add patches to allow build under Android.
1070 Provide our own header for the DNS protocol, rather than
1071 relying on arpa/nameser.h. This has proved more or less
1072 defective over the years and the final straw is that it's
1073 effectively empty on Android.
1075 Fix regression in 2.56 which caused hex constants in
1076 configuration to be rejected if they contain the '*'
1079 Correct wrong casts of arguments to ctype.h functions,
1080 isdigit(), isxdigit() etc. Thanks to Matthias Andree for
1083 Allow build with IDN support independently from i18n.
1084 IDN support continues to be included automatically
1085 when i18n is included.
1086 'make COPTS=-DHAVE_IDN' is the magic incantation.
1088 Modify check on extraneous command line junk (added in
1089 2.56) so that it doesn't complain about extra _empty_
1090 arguments. Otherwise this breaks libvirt.
1094 Add a patch to allow dnsmasq to get interface names right in a
1095 Solaris zone. Thanks to Dj Padzensky for this.
1097 Improve data-type parsing heuristics so that
1098 --dhcp-option=option:domain-search,.
1099 treats the value as a string and not an IP address.
1100 Thanks to Clemens Fischer for spotting that.
1102 Add IPv6 support to the TFTP server. Many thanks to Jan
1103 'RedBully' Seiffert for the patches.
1105 Log DNS queries at level LOG_INFO, rather then
1106 LOG_DEBUG. This makes things consistent with DHCP
1107 logging. Thanks to Adam Pribyl for spotting the problem.
1109 Ensure that dnsmasq terminates cleanly when using
1110 --syslog-async even if it cannot make a connection to the
1113 Add --add-mac option. This is to support currently
1114 experimental DNS filtering facilities. Thanks to Benjamin
1115 Petrin for the orignal patch.
1117 Fix bug which meant that tags were ignored in dhcp-range
1118 configuration specifying PXE-proxy service. Thanks to
1119 Cristiano Cumer for spotting this.
1121 Raise an error if there is extra junk, not part of an
1122 option, on the command line.
1124 Flag a couple of log messages in cache.c as coming from
1125 the DHCP subsystem. Thanks to Olaf Westrik for the patch.
1127 Omit timestamps from logs when a) logging to stderr and
1128 b) --keep-in-forground is set. The logging facility on the
1129 other end of stderr can be assumned to supply them. Thanks
1130 to John Hallam for the patch.
1132 Don't complain about strings longer than 255 characters in
1133 --txt-record, just split the long strings into 255
1134 character chunks instead.
1136 Fix crash on double-free. This bug can only happen when
1137 dhcp-script is in use and then only in rare circumstances
1138 triggered by high DHCP transaction rate and a slow
1139 script. Thanks to Ferenc Wagner for finding the problem.
1141 Only log that a file has been sent by TFTP after the
1142 transfer has completed succesfully.
1144 A good suggestion from Ferenc Wagner: extend
1145 the --domain option to allow this sort of thing:
1146 --domain=thekelleys.org.uk,192.168.0.0/24,local
1147 which automatically creates
1148 --local=/thekelleys.org.uk/
1149 --local=/0.168.192.in-addr.arpa/
1151 Tighten up syntax checking of hex contants in the config
1152 file. Thanks to Fred Damen for spotting this.
1154 Add dnsmasq logo/icon, contributed by Justin Swift. Many
1157 Never cache DNS replies which have the 'cd' bit set, or
1158 which result from queries forwarded with the 'cd' bit
1159 set. The 'cd' bit instructs a DNSSEC validating server
1160 upstream to ignore signature failures and return replies
1161 anyway. Without this change it's possible to pollute the
1162 dnsmasq cache with bad data by making a query with the
1163 'cd' bit set and subsequent queries would return this data
1164 without its being marked as suspect. Thanks to Anders
1165 Kaseorg for pointing out this problem.
1167 Add --proxy-dnssec flag, for compliance with RFC
1168 4035. Dnsmasq will now clear the 'ad' bit in answers returned
1169 from upstream validating nameservers unless this option is
1172 Allow a filename of "-" for --conf-file to read
1173 stdin. Suggestion from Timothy Redaelli.
1175 Rotate the order of SRV records in replies, to provide
1176 round-robin load balancing when all the priorities are
1177 equal. Thanks to Peter McKinney for the suggestion.
1180 contrib/MacOSX-launchd/uk.org.thekelleys.dnsmasq.plist
1181 so that it doesn't log all queries to a file by
1182 default. Thanks again to Peter McKinney.
1184 By default, setting an IPv4 address for a domain but not
1185 an IPv6 address causes dnsmasq to return
1186 an NODATA reply for IPv6 (or vice-versa). So
1187 --address=/google.com/1.2.3.4 stops IPv6 queries for
1188 *google.com from being forwarded. Make it possible to
1189 override this behaviour by defining the sematics if the
1190 same domain appears in both --server and --address.
1191 In that case, the --address has priority for the address
1192 family in which is appears, but the --server has priority
1193 of the address family which doesn't appear in --adddress
1195 --address=/google.com/1.2.3.4
1196 --server=/google.com/#
1197 will return 1.2.3.4 for IPv4 queries for *.google.com but
1198 forward IPv6 queries to the normal upstream nameserver.
1199 Similarly when setting an IPv6 address
1200 only this will allow forwarding of IPv4 queries. Thanks to
1201 William for pointing out the need for this.
1203 Allow more than one --dhcp-optsfile and --dhcp-hostsfile
1204 and make them understand directories as arguments in the
1205 same way as --addn-hosts. Suggestion from John Hanks.
1207 Ignore rebinding requests for leases we don't know
1208 about. Rebind is broadcast, so we might get to overhear a
1209 request meant for another DHCP server. NAKing this is
1210 wrong. Thanks to Brad D'Hondt for assistance with this.
1212 Fix cosmetic bug which produced strange output when
1213 dumping cache statistics with some configurations. Thanks
1214 to Fedor Kozhevnikov for spotting this.
1218 Fix crash when /etc/ethers is in use. Thanks to
1219 Gianluigi Tiesi for finding this.
1221 Fix crash in netlink_multicast(). Thanks to Arno Wald for
1224 Allow the empty domain "." in dhcp domain-search (119)
1229 There is no version 2.54 to avoid confusion with 2.53,
1230 which incorrectly identifies itself as 2.54.
1234 Fix failure to compile on Debian/kFreeBSD. Thanks to
1235 Axel Beckert and Petr Salinger.
1237 Fix code to avoid scary strict-aliasing warnings
1238 generated by gcc 4.4.
1240 Added FAQ entry warning about DHCP failures with Vista
1241 when firewalls block 255.255.255.255.
1243 Fixed bug which caused bad things to happen if a
1244 resolv.conf file which exists is subsequently removed.
1245 Thanks to Nikolai Saoukh for the patch.
1247 Rationalised the DHCP tag system. Every configuration item
1248 which can set a tag does so by adding "set:<tag>" and
1249 every configuration item which is conditional on a tag is
1250 made so by "tag:<tag>". The NOT operator changes to '!',
1251 which is a bit more intuitive too. Dhcp-host directives
1252 can set more than one tag now. The old '#' NOT,
1253 "net:" prefix and no-prefixes are still honoured, so
1254 no existing config file needs to be changed, but
1255 the documentation and new-style config files should be
1256 much less confusing.
1258 Added --tag-if to allow boolean operations on tags.
1259 This allows complicated logic to be clearer and more
1260 general. A great suggestion from Richard Voigt.
1262 Add broadcast/unicast information to DHCP logging.
1264 Allow --dhcp-broadcast to be unconditional.
1266 Fixed incorrect behaviour with NOT <tag> conditionals in
1267 dhcp-options. Thanks to Max Turkewitz for assistance
1270 If we send vendor-class encapsulated options based on the
1271 vendor-class supplied by the client, and no explicit
1272 vendor-class option is given, echo back the vendor-class
1275 Fix bug which stopped dnsmasq from matching both a
1276 circuitid and a remoteid. Thanks to Ignacio Bravo for
1279 Add --dhcp-proxy, which makes it possible to configure
1280 dnsmasq to use a DHCP relay agent as a full proxy, with
1281 all DHCP messages passing through the proxy. This is
1282 useful if the relay adds extra information to the packets
1283 it forwards, but cannot be configured with the RFC 5107
1284 server-override option.
1286 Added interface:<iface name> part to dhcp-range. The
1287 semantics of this are very odd at first sight, but it
1288 allows a single line of the form
1289 dhcp-range=interface:virt0,192.168.0.4,192.168.0.200
1290 to be added to dnsmasq configuration which then supplies
1291 DHCP and DNS services to that interface, without affecting
1292 what services are supplied to other interfaces and
1293 irrespective of the existance or lack of
1294 interface=<interface>
1295 lines elsewhere in the dnsmasq configuration. The idea is
1296 that such a line can be added automatically by libvirt
1297 or equivalent systems, without disturbing any manual
1300 Similarly to the above, allow --enable-tftp=<interface>
1302 Allow a TFTP root to be set separately for requests via
1303 different interfaces, --tftp-root=<path>,<interface>
1305 Correctly handle and log clashes between CNAMES and
1306 DNS names being given to DHCP leases. This fixes a bug
1307 which caused nonsense IP addresses to be logged. Thanks to
1308 Sergei Zhirikov for finding and analysing the problem.
1310 Tweak flush_log so as to avoid leaving the log
1311 file in non-blocking mode. O_NONBLOCK is a property of the
1312 file, not the process/descriptor.
1314 Fix contrib/Solaris10/create_package
1315 (/usr/man -> /usr/share/man) Thanks to Vita Batrla.
1317 Fix a problem where, if a client got a lease, then went
1318 to another subnet and got another lease, then moved back,
1319 it couldn't resume the old lease, but would instead get
1320 a new address. Thanks to Leonardo Rodrigues for spotting
1321 this and testing the fix.
1323 Fix weird bug which sometimes omitted certain characters
1324 from the start of quoted strings in dhcp-options. Thanks
1325 to Dayton Turner for spotting the problem.
1327 Add facility to redirect some domains to the standard
1328 upstream servers: this allows something like
1329 --server=/google.com/1.2.3.4 --server=/www.google.com/#
1330 which will send queries for *.google.com to 1.2.3.4,
1331 except *www.google.com which will be forwarded as usual.
1332 Thanks to AJ Weber for prompting this addition.
1334 Improve the hash-algorithm used to generate IP addresses
1335 from MAC addresses during initial DHCP address
1336 allocation. This improves performance when large numbers
1337 of hosts with similar MAC addresses all try and get an IP
1338 address at the same time. Thanks to Paul Smith for his
1341 Tweak DHCP code so that --bridge-interface can be used to
1342 select which IP alias of an interface should be used for
1343 DHCP purposes on Linux. If eth0 has an alias eth0:dhcp
1344 then adding --bridge-interface=eth0:dhcp,eth0 will use
1345 the address of eth0:dhcp to determine the correct subnet
1346 for DHCP address allocation. Thanks to Pawel Golaszewski
1347 for prompting this and Eric Cooper for further testing.
1349 Add --dhcp-generate-names. Suggestion by Ferenc Wagner.
1351 Tweak DNS server selection algorithm when there is more
1352 than one server available for a domain, eg.
1353 --server=/mydomain/1.1.1.1
1354 --server=/mydomain/2.2.2.2
1355 Thanks to Alberto Cuesta-Canada for spotting a weakness
1358 Add --max-ttl. Thanks to Fredrik Ringertz for the patch.
1360 Allow --log-facility=- to force all logging to
1361 stderr. Suggestion from Clemens Fischer.
1363 Fix regression which caused configuration like
1364 --address=/.domain.com/1.2.3.4 to be rejected. The dot to the
1365 left of the domain has been implied and not required for a
1366 long time, but it should be accepted for backward
1367 compatibility. Thanks to Andrew Burcin for spotting this.
1369 Add --rebind-domain-ok and --rebind-localhost-ok.
1370 Suggestion from Clemens Fischer.
1372 Log replies to queries of type TXT, when --log-queries
1375 Fix compiler warnings when compiled with -DNO_DHCP. Thanks
1376 to Shantanu Gadgil for the patch.
1378 Updated French translation. Thanks to Gildas Le Nadan.
1380 Updated Polish translation. Thanks to Jan Psota.
1382 Updated German translation. Thanks to Matthias Andree.
1384 Added contrib/static-arp, thanks to Darren Hoo.
1386 Fix corruption of the domain when a name from /etc/hosts
1387 overrides one supplied by a DHCP client. Thanks to Fedor
1388 Kozhevnikov for spotting the problem.
1390 Updated Spanish translation. Thanks to Chris Chatham.
1394 Work around a Linux kernel bug which insists that the
1395 length of the option passed to setsockopt must be at least
1396 sizeof(int) bytes, even if we're calling SO_BINDTODEVICE
1397 and the device name is "lo". Note that this is fixed
1398 in kernel 2.6.31, but the workaround is harmless and
1399 allows earlier kernels to be used. Also fix dnsmasq
1400 bug which reported the wrong address when this failed.
1401 Thanks to Fedor for finding this.
1403 The API for IPv6 PKTINFO changed around Linux kernel
1404 2.6.14. Workaround the case where dnsmasq is compiled
1405 against newer headers, but then run on an old kernel:
1406 necessary for some *WRT distros.
1408 Re-read the set of network interfaces when re-loading
1409 /etc/resolv.conf if --bind-interfaces is not set. This
1410 handles the case that loopback interfaces do not exist
1411 when dnsmasq is first started.
1413 Tweak the PXE code to support port 4011. This should
1414 reduce broadcasts and make things more reliable when other
1415 servers are around. It also improves inter-operability
1416 with certain clients.
1418 Make a pxe-service configuration with no filename or boot
1419 service type legal: this does a local boot. eg.
1420 pxe-service=x86PC, "Local boot"
1422 Be more conservative in detecting "A for A"
1423 queries. Dnsmasq checks if the name in a type=A query looks
1424 like a dotted-quad IP address and answers the query itself
1425 if so, rather than forwarding it. Previously dnsmasq
1426 relied in the library function inet_addr() to convert
1427 addresses, and that will accept some things which are
1428 confusing in this context, like 1.2.3 or even just
1429 1234. Now we only do A for A processing for four decimal
1430 numbers delimited by dots.
1432 A couple of tweaks to fix compilation on Solaris. Thanks
1433 to Joel Macklow for help with this.
1435 Another Solaris compilation tweak, needed for Solaris
1436 2009.06. Thanks to Lee Essen for that.
1438 Added extract packaging stuff from Lee Essen to
1441 Increased the default limit on number of leases to 1000
1442 (from 150). This is mainly a defence against DoS attacks,
1443 and for the average "one for two class C networks"
1444 installation, IP address exhaustion does that just as
1445 well. Making the limit greater than the number of IP
1446 addresses available in such an installation removes a
1447 surprise which otherwise can catch people out.
1449 Removed extraneous trailing space in the value of the
1450 DNSMASQ_TIME_REMAINING DNSMASQ_LEASE_LENGTH and
1451 DNSMASQ_LEASE_EXPIRES environment variables. Thanks to
1452 Gildas Le Nadan for spotting this.
1454 Provide the network-id tags for a DHCP transaction to
1455 the lease-change script in the environment variable
1456 DNSMASQ_TAGS. A good suggestion from Gildas Le Nadan.
1458 Add support for RFC3925 "Vendor-Identifying Vendor
1459 Options". The syntax looks like this:
1460 --dhcp-option=vi-encap:<enterprise number>, .........
1462 Add support to --dhcp-match to allow matching against
1463 RFC3925 "Vendor-Identifying Vendor Classes". The syntax
1465 --dhcp-match=tag,vi-encap<enterprise number>, <value>
1467 Add some application specific code to assist in
1468 implementing the Broadband forum TR069 CPE-WAN
1469 specification. The details are in contrib/CPE-WAN/README
1471 Increase the default DNS packet size limit to 4096, as
1472 recommended by RFC5625 section 4.4.3. This can be
1473 reconfigured using --edns-packet-max if needed. Thanks to
1474 Francis Dupont for pointing this out.
1476 Rewrite query-ids even for TSIG signed packets, since
1477 this is allowed by RFC5625 section 4.5.
1479 Use getopt_long by default on OS X. It has been supported
1480 since version 10.3.0. Thanks to Arek Dreyer for spotting
1483 Added up-to-date startup configuration for MacOSX/launchd
1484 in contrib/MacOSX-launchd. Thanks to Arek Dreyer for
1487 Fix link error when including Dbus but excluding DHCP.
1488 Thanks to Oschtan for the bug report.
1490 Updated French translation. Thanks to Gildas Le Nadan.
1492 Updated Polish translation. Thanks to Jan Psota.
1494 Updated Spanish translation. Thanks to Chris Chatham.
1496 Fixed confusion about domains, when looking up DHCP hosts
1497 in /etc/hosts. This could cause spurious "Ignoring
1498 domain..." messages. Thanks to Fedor Kozhevnikov for
1499 finding and analysing the problem.
1503 Add support for internationalised DNS. Non-ASCII characters
1504 in domain names found in /etc/hosts, /etc/ethers and
1505 /etc/dnsmasq.conf will be correctly handled by translation to
1506 punycode, as specified in RFC3490. This function is only
1507 available if dnsmasq is compiled with internationalisation
1508 support, and adds a dependency on GNU libidn. Without i18n
1509 support, dnsmasq continues to be compilable with just
1510 standard tools. Thanks to Yves Dorfsman for the
1513 Add two more environment variables for lease-change scripts:
1514 First, DNSMASQ_SUPPLIED_HOSTNAME; this is set to the hostname
1515 supplied by a client, even if the actual hostname used is
1516 over-ridden by dhcp-host or dhcp-ignore-names directives.
1517 Also DNSMASQ_RELAY_ADDRESS which gives the address of
1518 a DHCP relay, if used.
1519 Suggestions from Michael Rack.
1521 Fix regression which broke echo of relay-agent
1522 options. Thanks to Michael Rack for spotting this.
1524 Don't treat option 67 as being interchangeable with
1525 dhcp-boot parameters if it's specified as
1528 Make the code to call scripts on lease-change compile-time
1529 optional. It can be switched off by editing src/config.h
1530 or building with "make COPTS=-DNO_SCRIPT".
1532 Make the TFTP server cope with filenames from Windows/DOS
1533 which use '\' as pathname separator. Thanks to Ralf for
1536 Updated Polish translation. Thanks to Jan Psota.
1538 Warn if an IP address is duplicated in /etc/ethers. Thanks
1539 to Felix Schwarz for pointing this out.
1541 Teach --conf-dir to take an option list of file suffices
1542 which will be ignored when scanning the directory. Useful
1543 for backup files etc. Thanks to Helmut Hullen for the
1546 Add new DHCP option named tftpserver-address, which
1547 corresponds to the third argument of dhcp-boot. This
1548 allows the complete functionality of dhcp-boot to be
1549 replicated with dhcp-option. Useful when using
1552 Test which upstream nameserver to use every 10 seconds
1553 or 50 queries and not just when a query times out and
1554 is retried. This should improve performance when there
1555 is a slow nameserver in the list. Thanks to Joe for the
1558 Don't do any PXE processing, even for clients with the
1559 correct vendorclass, unless at least one pxe-prompt or
1560 pxe-service option is given. This stops dnsmasq
1561 interfering with proxy PXE subsystems when it is just
1562 the DHCP server. Thanks to Spencer Clark for spotting this.
1564 Limit the blocksize used for TFTP transfers to a value
1565 which avoids packet fragmentation, based on the MTU of the
1566 local interface. Many netboot ROMs can't cope with
1569 Honour dhcp-ignore configuration for PXE and proxy-PXE
1570 requests. Thanks to Niels Basjes for the bug report.
1572 Updated French translation. Thanks to Gildas Le Nadan.
1576 Fix security problem which allowed any host permitted to
1577 do TFTP to possibly compromise dnsmasq by remote buffer
1578 overflow when TFTP enabled. Thanks to Core Security
1579 Technologies and Iván Arce, Pablo Hernán Jorge, Alejandro
1580 Pablo Rodriguez, Martín Coco, Alberto Soliño Testa and
1581 Pablo Annetta. This problem has Bugtraq id: 36121
1584 Fix a problem which allowed a malicious TFTP client to
1585 crash dnsmasq. Thanks to Steve Grubb at Red Hat for
1586 spotting this. This problem has Bugtraq id: 36120 and
1591 Fix regression in 2.48 which disables the lease-change
1592 script. Thanks to Jose Luis Duran for spotting this.
1594 Log TFTP "file not found" errors. These were not logged,
1595 since a normal PXELinux boot generates many of them, but
1596 the lack of the messages seems to be more confusing than
1597 routinely seeing them when there is no real error.
1599 Update Spanish translation. Thanks to Chris Chatham.
1603 Archived the extensive, backwards, changelog to
1604 CHANGELOG.archive. The current changelog now runs from
1605 version 2.43 and runs conventionally.
1607 Fixed bug which broke binding of servers to physical
1608 interfaces when interface names were longer than four
1609 characters. Thanks to MURASE Katsunori for the patch.
1611 Fixed netlink code to check that messages come from the
1612 correct source, and not another userspace process. Thanks
1613 to Steve Grubb for the patch.
1615 Maintainability drive: removed bug and missing feature
1616 workarounds for some old platforms. Solaris 9, OpenBSD
1617 older than 4.1, Glibc older than 2.2, Linux 2.2.x and
1618 DBus older than 1.1.x are no longer supported.
1620 Don't read included configuration files more than once:
1621 allows complex configuration structures without problems.
1623 Mark log messages from the various subsystems in dnsmasq:
1624 messages from the DHCP subsystem now have the ident string
1625 "dnsmasq-dhcp" and messages from TFTP have ident
1626 "dnsmasq-tftp". Thanks to Olaf Westrik for the patch.
1628 Fix possible infinite DHCP protocol loop when an IP
1629 address nailed to a hostname (not a MAC address) and a
1630 host sometimes provides the name, sometimes not.
1632 Allow --addn-hosts to take a directory: all the files
1633 in the directory are read. Thanks to Phil Cornelius for
1636 Support --bridge-interface on all platforms, not just BSD.
1638 Added support for advanced PXE functions. It's now
1639 possible to define a prompt and menu options which will
1640 be displayed when a client PXE boots. It's also possible to
1641 hand-off booting to other boot servers. Proxy-DHCP, where
1642 dnsmasq just supplies the PXE information and another DHCP
1643 server does address allocation, is also allowed. See the
1644 --pxe-prompt and --pxe-service keywords. Thanks to
1645 Alkis Georgopoulos for the suggestion and Guilherme Moro
1646 and Michael Brown for assistance.
1648 Improvements to DHCP logging. Thanks to Tom Metro for
1651 Add ability to build dnsmasq without DHCP support. To do
1652 this, edit src/config.h or build with
1653 "make COPTS=-DNO_DHCP". Thanks to Mahavir Jain for the patch.
1655 Added --test command-line switch - syntax check
1656 configuration files only.
1658 Updated French translation. Thanks to Gildas Le Nadan.
1662 Updated French translation. Thanks to Gildas Le Nadan.
1664 Fixed interface enumeration code to work on NetBSD
1665 5.0. Thanks to Roy Marples for the patch.
1667 Updated config.h to use the same location for the lease
1668 file on NetBSD as the other *BSD variants. Also allow
1669 LEASEFILE and CONFFILE symbols to be overriden in CFLAGS.
1671 Handle duplicate address detection on IPv6 more
1672 intelligently. In IPv6, an interface can have an address
1673 which is not usable, because it is still undergoing DAD
1674 (such addresses are marked "tentative"). Attempting to
1675 bind to an address in this state returns an error,
1676 EADDRNOTAVAIL. Previously, on getting such an error,
1677 dnsmasq would silently abandon the address, and never
1678 listen on it. Now, it retries once per second for 20
1679 seconds before generating a fatal error. 20 seconds should
1680 be long enough for any DAD process to complete, but can be
1681 adjusted in src/config.h if necessary. Thanks to Martin
1682 Krafft for the bug report.
1684 Add DBus introspection. Patch from Jeremy Laine.
1686 Update Dbus configuration file. Patch from Colin Walters.
1688 http://bugs.freedesktop.org/show_bug.cgi?id=18961
1690 Support arbitrarily encapsulated DHCP options, suggestion
1691 and initial patch from Samium Gromoff. This is useful for
1692 (eg) gPXE, which expect all its private options to be
1693 encapsulated inside a single option 175. So, eg,
1695 dhcp-option = encap:175, 190, "iscsi-client0"
1696 dhcp-option = encap:175, 191, "iscsi-client0-secret"
1698 will provide iSCSI parameters to gPXE.
1700 Enhance --dhcp-match to allow testing of the contents of a
1701 client-sent option, as well as its presence. This
1702 application in mind for this is RFC 4578
1703 client-architecture specifiers, but it's generally useful.
1704 Joey Korkames suggested the enhancement.
1706 Move from using the IP_XMIT_IF ioctl to IP_BOUND_IF on
1707 OpenSolaris. Thanks to Bastian Machek for the heads-up.
1709 No longer complain about blank lines in
1710 /etc/ethers. Thanks to Jon Nelson for the patch.
1712 Fix binding of servers to physical devices, eg
1713 --server=/domain/1.2.3.4@eth0 which was broken from 2.43
1714 onwards unless --query-port=0 set. Thanks to Peter Naulls
1717 Reply to DHCPINFORM requests even when the supplied ciaddr
1718 doesn't fall in any dhcp-range. In this case it's not
1719 possible to supply a complete configuration, but
1720 individually-configured options (eg PAC) may be useful.
1722 Allow the source address of an alias to be a range:
1723 --alias=192.168.0.0,10.0.0.0,255.255.255.0 maps the whole
1724 subnet 192.168.0.0->192.168.0.255 to 10.0.0.0->10.0.0.255,
1726 --alias=192.168.0.10-192.168.0.40,10.0.0.0,255.255.255.0
1727 maps only the 192.168.0.10->192.168.0.40 region. Thanks to
1728 Ib Uhrskov for the suggestion.
1730 Don't dynamically allocate DHCP addresses which may break
1731 Windows. Addresses which end in .255 or .0 are broken in
1732 Windows even when using supernetting.
1733 --dhcp-range=192.168.0.1,192.168.1.254,255,255,254.0 means
1734 192.168.0.255 is a valid IP address, but not for Windows.
1735 See Microsoft KB281579. We therefore no longer allocate
1736 these addresses to avoid hard-to-diagnose problems.
1738 Update Polish translation. Thanks to Jan Psota.
1740 Delete the PID-file when dnsmasq shuts down. Note that by
1741 this time, dnsmasq is normally not running as root, so
1742 this will fail if the PID-file is stored in a root-owned
1743 directory; such failure is silently ignored. To take
1744 advantage of this feature, the PID-file must be stored in a
1745 directory owned and write-able by the user running
1750 Allow --bootp-dynamic to take a netid tag, so that it may
1751 be selectively enabled. Thanks to Olaf Westrik for the
1754 Remove ISC-leasefile reading code. This has been
1755 deprecated for a long time, and last time I removed it, it
1756 ended up going back by request of one user. This time,
1757 it's gone for good; otherwise it would need to be
1758 re-worked to support multiple domains (see below).
1760 Support DHCP clients in multiple DNS domains. This is a
1761 long-standing request. Clients are assigned to a domain
1762 based in their IP address.
1764 Add --dhcp-fqdn flag, which changes behaviour if DNS names
1765 assigned to DHCP clients. When this is set, there must be
1766 a domain associated with each client, and only
1767 fully-qualified domain names are added to the DNS. The
1768 advantage is that the only the FQDN needs to be unique,
1769 so that two or more DHCP clients can share a hostname, as
1770 long as they are in different domains.
1772 Set environment variable DNSMASQ_DOMAIN when invoking
1773 lease-change script. This may be useful information to
1774 have now that it's variable.
1776 Tighten up data-checking code for DNS packet
1777 handling. Thanks to Steve Dodd who found certain illegal
1778 packets which could crash dnsmasq. No memory overwrite was
1779 possible, so this is not a security issue beyond the DoS
1782 Update example config dhcp option 47, the previous
1783 suggestion generated an illegal, zero-length,
1784 option. Thanks to Matthias Andree for finding this.
1786 Rewrite hosts-file reading code to remove the limit of
1787 1024 characters per line. John C Meuser found this.
1789 Create a net-id tag with the name of the interface on
1790 which the DHCP request was received.
1792 Fixed minor memory leak in DBus code, thanks to Jeremy
1793 Laine for the patch.
1795 Emit DBus signals as the DHCP lease database
1796 changes. Thanks to Jeremy Laine for the patch.
1798 Allow for more that one MAC address in a dhcp-host
1799 line. This configuration tells dnsmasq that it's OK to
1800 abandon a DHCP lease of the fixed address to one MAC
1801 address, if another MAC address in the dhcp-host statement
1802 asks for an address. This is useful to give a fixed
1803 address to a host which has two network interfaces
1804 (say, a laptop with wired and wireless interfaces.)
1805 It's very important to ensure that only one interface
1806 at a time is up, since dnsmasq abandons the first lease
1807 and re-uses the address before the leased time has
1808 elapsed. John Gray suggested this.
1810 Tweak the response to a DHCP request packet with a wrong
1811 server-id when --dhcp-authoritative is set; dnsmasq now
1812 returns a DHCPNAK, rather than silently ignoring the
1813 packet. Thanks to Chris Marget for spotting this
1816 Add --cname option. This provides a limited alias
1817 function, usable for DHCP names. Thanks to AJ Weber for
1818 suggestions on this.
1820 Updated contrib/webmin with latest version from Neil
1823 Updated Polish translation. Thanks to Jan Psota.
1825 Correct the text names for DHCP options 64 and 65 to be
1826 "nis+-domain" and "nis+-servers".
1828 Updated Spanish translation. Thanks to Chris Chatham.
1830 Force re-reading of /etc/resolv.conf when an "interface
1835 Fix total DNS failure in release 2.44 unless --min-port
1836 specified. Thanks to Steven Barth and Grant Coady for
1837 bugreport. Also reject out-of-range port spec, which could
1838 break things too: suggestion from Gilles Espinasse.
1842 Fix crash when unknown client attempts to renew a DHCP
1843 lease, problem introduced in version 2.43. Thanks to
1844 Carlos Carvalho for help chasing this down.
1846 Fix potential crash when a host which doesn't have a lease
1847 does DHCPINFORM. Again introduced in 2.43. This bug has
1848 never been reported in the wild.
1850 Fix crash in netlink code introduced in 2.43. Thanks to
1851 Jean Wolter for finding this.
1853 Change implementation of min_port to work even if min-port
1856 Patch to enable compilation of latest Mac OS X. Thanks to
1859 Update Spanish translation. Thanks to Christopher Chatham.
1863 Updated Polish translation. Thanks to Jan Psota.
1865 Flag errors when configuration options are repeated
1868 Further tweaks for GNU/kFreeBSD
1870 Add --no-wrap to msgmerge call - provides nicer .po file
1873 Honour lease-time spec in dhcp-host lines even for
1874 BOOTP. The user is assumed to known what they are doing in
1875 this case. (Hosts without the time spec still get infinite
1876 leases for BOOTP, over-riding the default in the
1877 dhcp-range.) Thanks to Peter Katzmann for uncovering this.
1879 Fix problem matching relay-agent ids. Thanks to Michael
1880 Rack for the bug report.
1882 Add --naptr-record option. Suggestion from Johan
1885 Implement RFC 5107 server-id-override DHCP relay agent
1888 Apply patches from Stefan Kruger for compilation on
1889 Solaris 10 under Sun studio.
1891 Yet more tweaking of Linux capability code, to suppress
1892 pointless wingeing from kernel 2.6.25 and above.
1894 Improve error checking during startup. Previously, some
1895 errors which occurred during startup would be worked
1896 around, with dnsmasq still starting up. Some were logged,
1897 some silent. Now, they all cause a fatal error and dnsmasq
1898 terminates with a non-zero exit code. The errors are those
1899 associated with changing uid and gid, setting process
1900 capabilities and writing the pidfile. Thanks to Uwe
1901 Gansert and the Suse security team for pointing out
1902 this improvement, and Bill Reimers for good implementation
1905 Provide NO_LARGEFILE compile option to switch off largefile
1906 support when compiling against versions of uclibc which
1907 don't support it. Thanks to Stephane Billiart for the patch.
1909 Implement random source ports for interactions with
1910 upstream nameservers. New spoofing attacks have been found
1911 against nameservers which do not do this, though it is not
1912 clear if dnsmasq is vulnerable, since to doesn't implement
1913 recursion. By default dnsmasq will now use a different
1914 source port (and socket) for each query it sends
1915 upstream. This behaviour can suppressed using the
1916 --query-port option, and the old default behaviour
1917 restored using --query-port=0. Explicit source-port
1918 specifications in --server configs are still honoured.
1920 Replace the random number generator, for better
1921 security. On most BSD systems, dnsmasq uses the
1922 arc4random() RNG, which is secure, but on other platforms,
1923 it relied on the C-library RNG, which may be
1924 guessable and therefore allow spoofing. This release
1925 replaces the libc RNG with the SURF RNG, from Daniel
1926 J. Berstein's DJBDNS package.
1928 Don't attempt to change user or group or set capabilities
1929 if dnsmasq is run as a non-root user. Without this, the
1930 change from soft to hard errors when these fail causes
1931 problems for non-root daemons listening on high
1932 ports. Thanks to Patrick McLean for spotting this.
1934 Updated French translation. Thanks to Gildas Le Nadan.
1938 The changelog for version 2.42 and earlier is
1939 available in CHANGELOG.archive.
