2 Add the ability to act as an authoritative DNS
3 server. Dnsmasq can now answer queries from the wider 'net
4 with local data, as long as the correct NS records are set
5 up. Only local data is provided, to avoid creating an open
6 DNS relay. Zone transfer is supported, to allow secondary
7 servers to be configured.
9 Add "constructed DHCP ranges" for DHCPv6. This is intended
10 for IPv6 routers which get prefixes dynamically via prefix
11 delegation. With suitable configuration, stateful DHCPv6
12 and RA can happen automatically as prefixes are delegated
13 and then deprecated, without having to re-write the
14 dnsmasq configuration file or restart the daemon. Thanks to
15 Steven Barth for extensive testing and development work on
18 Fix crash on startup on Solaris 11. Regression probably
19 introduced in 2.61. Thanks to Geoff Johnstone for the
22 Add code to make behaviour for TCP DNS requests that same
23 as for UDP requests, when a request arrives for an allowed
24 address, but via a banned interface. This change is only
25 active on Linux, since the relevant API is missing (AFAIK)
26 on other platforms. Many thanks to Tomas Hozza for
27 spotting the problem, and doing invaluable discovery of
28 the obscure and undocumented API required for the solution.
30 Don't send the default DHCP option advertising dnsmasq as
31 the local DNS server if dnsmasq is configured to not act
32 as DNS server, or it's configured to a non-standard port.
34 Add DNSMASQ_CIRCUIT_ID, DNSMASQ_SUBCRIBER_ID,
35 DNSMASQ_REMOTE_ID variables to the environment of the
36 lease-change script (and the corresponding Lua). These hold
37 information inserted into the DHCP request by a DHCP relay
38 agent. Thanks to Lakefield Communications for providing a
39 bounty for this addition.
41 Fixed crash, introduced in 2.64, whilst handling DHCPv6
42 information-requests with some common configurations.
43 Thanks to Robert M. Albrecht for the bug report and
46 Add --ipset option. Thanks to Jason A. Donenfeld for the
49 Don't erroneously reject some option names in --dhcp-match
50 options. Thanks to Benedikt Hochstrasser for the bug report.
52 Allow a trailing '*' wildcard in all interface-name
53 configurations. Thanks to Christian Parpart for the patch.
55 Handle the situation where libc headers define
56 SO_REUSEPORT, but the kernel in use doesn't, to cope with
57 the introduction of this option to Linux. Thanks to Rich
58 Felker for the bug report.
62 Fix regression which broke forwarding of queries sent via
63 TCP which are not for A and AAAA and which were directed to
64 non-default servers. Thanks to Niax for the bug report.
66 Fix failure to build with DHCP support excluded. Thanks to
67 Gustavo Zacarias for the patch.
69 Fix nasty regression in 2.64 which completely broke cacheing.
73 Handle DHCP FQDN options with all flag bits zero and
74 --dhcp-client-update set. Thanks to Bernd Krumbroeck for
77 Finesse the check for /etc/hosts names which conflict with
78 DHCP names. Previously a name/address pair in /etc/hosts
79 which didn't match the name/address of a DHCP lease would
80 generate a warning. Now that only happesn if there is not
81 also a match. This allows multiple addresses for a name in
82 /etc/hosts with one of them assigned via DHCP.
84 Fix broken vendor-option processing for BOOTP. Thanks to
85 Hans-Joachim Baader for the bug report.
87 Don't report spurious netlink errors, regression in
88 2.63. Thanks to Vladislav Grishenko for the patch.
90 Flag DHCP or DHCPv6 in starup logging. Thanks to
91 Vladislav Grishenko for the patch.
93 Add SetServersEx method in DBus interface. Thanks to Dan
94 Williams for the patch.
96 Add SetDomainServers method in DBus interface. Thanks to
97 Roy Marples for the patch.
99 Fix build with later Lua libraries. Thansk to Cristian
100 Rodriguez for the patch.
102 Add --max-cache-ttl option. Thanks to Dennis Kaarsemaker
105 Fix breakage of --host-record parsing, resulting in
106 infinte loop at startup. Regression in 2.63. Thanks to
107 Haim Gelfenbeyn for spotting this.
109 Set SO_REUSEADDRESS and SO_V6ONLY options on the DHCPv6
110 socket, this allows multiple instances of dnsmasq on a
111 single machine, in the same way as for DHCPv4. Thanks to
112 Gene Czarcinski and Vladislav Grishenko for work on this.
114 Fix DHCPv6 to do access control correctly when it's
115 configured with --listen-address. Thanks to
116 Gene Czarcinski for sorting this out.
118 Add a "wildcard" dhcp-range which works for any IPv6
119 subnet, --dhcp-range=::,static Useful for Stateless
120 DHCPv6. Thanks to Vladislav Grishenko for the patch.
122 Don't include lease-time in DHCPACK replies to DHCPINFORM
123 queries, since RFC-2131 says we shouldn't. Thanks to
124 Wouter Ibens for pointing this out.
126 Makefile tweak to do dependency checking on header files.
127 Thanks to Johan Peeters for the patch.
129 Check interface for outgoing unsolicited router
130 advertisements, rather than relying on interface address
131 configuration. Thanks to Gene Czarinski for the patch.
133 Handle better attempts to transmit on interfaces which are
134 still doing DAD, and specifically do not just transmit
135 without setting source address and interface, since this
136 can cause very puzzling effects when a router
137 advertisement goes astray. Thanks again to Gene Czarinski.
139 Get RA timers right when there is more than one
140 dhcp-range on a subnet.
144 Do duplicate dhcp-host address check in --test mode.
146 Check that tftp-root directories are accessible before
147 start-up. Thanks to Daniel Veillard for the initial patch.
149 Allow more than one --tfp-root flag. The per-interface
150 stuff is pointless without that.
152 Add --bind-dynamic. A hybrid mode between the default and
153 --bind-interfaces which copes with dynamically created
156 A couple of fixes to the build system for Android. Thanks
157 to Metin Kaya for the patches.
159 Remove the interface:<interface> argument in --dhcp-range, and
160 the interface argument to --enable-tftp. These were a
161 still-born attempt to allow automatic isolated
162 configuration by libvirt, but have never (to my knowledge)
163 been used, had very strange semantics, and have been
164 superceded by other mechanisms.
166 Fixed bug logging filenames when duplicate dhcp-host
167 addresses are found. Thanks to John Hanks for the patch.
169 Fix regression in 2.61 which broke caching of CNAME
170 chains. Thanks to Atul Gupta for the bug report.
172 Allow the target of a --cname flag to be another --cname.
174 Teach DHCPv6 about the RFC 4242 information-refresh-time
175 option, and add parsing if the minutes, hours and days
176 format for options. Thanks to Francois-Xavier Le Bail for
179 Allow "w" (for week) as multiplier in lease times, as well
180 as seconds, minutes, hours and days. Álvaro Gámez Machado
181 spotted the ommission.
183 Update French translation. Thanks to Gildas Le Nadan.
185 Allow a DBus service name to be given with --enable-dbus
186 which overrides the default,
187 uk.org.thekelleys.dnsmasq. Thanks to Mathieu
188 Trudel-Lapierre for the patch.
190 Set the "prefix on-link" bit in Router
191 Advertisements. Thanks to Gui Iribarren for the patch.
195 Update German translation. Thanks to Conrad Kostecki.
197 Cope with router-solict packets wich don't have a valid
198 source address. Thanks to Vladislav Grishenko for the patch.
200 Fixed bug which caused missing periodic router
201 advertisements with some configurations. Thanks to
202 Vladislav Grishenko for the patch.
204 Fixed bug which broke DHCPv6/RA with prefix lengths
205 which are not divisible by 8. Thanks to Andre Coetzee
208 Fix non-response to router-solicitations when
209 router-advertisement configured, but DHCPv6 not
210 configured. Thanks to Marien Zwart for the patch.
212 Add --dns-rr, to allow arbitrary DNS resource records.
214 Fixed bug which broke RA scheduling when an interface had
215 two addresses in the same network. Thanks to Jim Bos for
216 his help nailing this.
219 Re-write interface discovery code on *BSD to use
220 getifaddrs. This is more portable, more straightforward,
221 and allows us to find the prefix length for IPv6
224 Add ra-names, ra-stateless and slaac keywords for DHCPv6.
225 Dnsmasq can now synthesise AAAA records for dual-stack
226 hosts which get IPv6 addresses via SLAAC. It is also now
227 possible to use SLAAC and stateless DHCPv6, and to
228 tell clients to use SLAAC addresses as well as DHCP ones.
229 Thanks to Dave Taht for help with this.
231 Add --dhcp-duid to allow DUID-EN uids to be used.
233 Explicity send DHCPv6 replies to the correct port, instead
234 of relying on clients to send requests with the correct
235 source address, since at least one client in the wild gets
236 this wrong. Thanks to Conrad Kostecki for help tracking
239 Send a preference value of 255 in DHCPv6 replies when
240 --dhcp-authoritative is in effect. This tells clients not
241 to wait around for other DHCP servers.
243 Better logging of DHCPv6 options.
245 Add --host-record. Thanks to Rob Zwissler for the
248 Invoke the DHCP script with action "tftp" when a TFTP file
249 transfer completes. The size of the file, address to which
250 it was sent and complete pathname are supplied. Note that
251 version 2.60 introduced some script incompatibilties
252 associated with DHCPv6, and this is a further change. To
253 be safe, scripts should ignore unknown actions, and if
254 not IPv6-aware, should exit if the environment
255 variable DNSMASQ_IAID is set. The use-case for this is
256 to track netboot/install. Suggestion from Shantanu
259 Update contrib/port-forward/dnsmasq-portforward to reflect
262 Set the environment variable DNSMASQ_LOG_DHCP when running
263 the script id --log-dhcp is in effect, so that script can
264 taylor their logging verbosity. Suggestion from Malte
267 Arrange that addresses specified with --listen-address
268 work even if there is no interface carrying the
269 address. This is chiefly useful for IPv4 loopback
270 addresses, where any address in 127.0.0.0/8 is a valid
271 loopback address, but normally only 127.0.0.1 appears on
272 the lo interface. Thanks to Mathieu Trudel-Lapierre for
273 the idea and initial patch.
275 Fix crash, introduced in 2.60, when a DHCPINFORM is
276 received from a network which has no valid dhcp-range.
277 Thanks to Stephane Glondu for the bug report.
279 Add a new DHCP lease time keyword, "deprecated" for
280 --dhcp-range. This is only valid for IPv6, and sets the
281 preffered lease time for both DHCP and RA to zero. The
282 effect is that clients can continue to use the address
283 for existing connections, but new connections will use
284 other addresses, if they exist. This makes hitless
285 renumbering at least possible.
287 Fix bug in address6_available() which caused DHCPv6 lease
288 aquisition to fail if more than one dhcp-range in use.
290 Provide RDNSS and DNSSL data in router advertisements,
291 using the settings provided for DHCP options
292 option6:domain-search and option6:dns-server.
294 Tweak logo/favicon.ico to add some transparency. Thanks to
295 SamLT for work on this.
297 Don't cache data from non-recursive nameservers, since it
298 may erroneously look like a valid CNAME to a non-exitant
299 name. Thanks to Ben Winslow for finding this.
301 Call SO_BINDTODEVICE on the DHCP socket(s) when doing DHCP
302 on exactly one interface and --bind-interfaces is set. This
303 makes the OpenStack use-case of one dnsmasq per virtual
304 interface work. This is only available on Linux; it's not
305 supported on other platforms. Thanks to Vishvananda Ishaya
306 and the OpenStack team for the suggestion.
308 Updated French translation. Thanks to Gildas Le Nadan.
310 Give correct from-cache answers to explict CNAME queries.
311 Thanks to Rob Zwissler for spotting this.
313 Add --tftp-lowercase option. Thanks to Oliver Rath for the
316 Ensure that the DBus DhcpLeaseUpdated events are generated
317 when a lease goes through INIT_REBOOT state, even if the
318 dhcp-script is not in use. Thanks to Antoaneta-Ecaterina
321 Fix failure of TFTP over IPv4 on OpenBSD platform. Thanks
322 to Brad Smith for spotting this.
326 Fix compilation problem in Mac OS X Lion. Thanks to Olaf
327 Flebbe for the patch.
329 Fix DHCP when using --listen-address with an IP address
330 which is not the primary address of an interface.
332 Add --dhcp-client-update option.
334 Add Lua integration. Dnsmasq can now execute a DHCP
335 lease-change script written in Lua. This needs to be
336 enabled at compile time by setting HAVE_LUASCRIPT in
337 src/config.h or running "make COPTS=-DHAVE_LUASCRIPT"
338 Thanks to Jan-Piet Mens for the idea and proof-of-concept
341 Tidied src/config.h to distinguish between
342 platform-dependent compile-time options which are selected
343 automatically, and builder-selectable compile time
344 options. Document the latter better, and describe how to
345 set them from the make command line.
347 Tidied up IPPROTO_IP/SOL_IP (and IPv6 equivalent)
348 confusion. IPPROTO_IP works everywhere now.
350 Set TOS on DHCP sockets, this improves things on busy
351 wireless networks. Thanks to Dave Taht for the patch.
353 Determine VERSION automatically based on git magic:
354 release tags or hash values.
356 Improve start-up speed when reading large hosts files
357 containing many distinct addresses.
359 Fix problem if dnsmasq is started without the stdin,
360 stdout and stderr file descriptors open. This can manifest
361 itself as 100% CPU use. Thanks to Chris Moore for finding
364 Fix shell-scripting bug in bld/pkg-wrapper. Thanks to
365 Mark Mitchell for the patch.
367 Allow the TFP server or boot server in --pxe-service, to
368 be a domain name instead of an IP address. This allows for
369 round-robin to multiple servers, in the same way as
370 --dhcp-boot. A good suggestion from Cristiano Cumer.
372 Support BUILDDIR variable in the Makefile. Allows builds
373 for multiple archs from the same source tree with eg.
374 make BUILDDIR=linux (relative to dnsmasq tree)
375 make BUILDDIR=/tmp/openbsd (absolute path)
376 If BUILDDIR is not set, compilation happens in the src
377 directory, as before. Suggestion from Mark Mitchell.
379 Support DHCPv6. Support is there for the sort of things
380 the existing v4 server does, including tags, options,
381 static addresses and relay support. Missing is prefix
382 delegation, which is probably not required in the dnsmasq
383 niche, and an easy way to accept prefix delegations from
384 an upstream DHCPv6 server, which is. Future plans include
385 support for DHCPv6 router option and MAC address option
386 (to make selecting clients by MAC address work like IPv4).
387 These will be added as the standards mature.
388 This code has been tested, but this is the first release,
389 so don't bet the farm on it just yet. Many thanks to all
390 testers who have got it this far.
392 Support IPv6 router advertisements. This is a
393 simple-minded implementation, aimed at providing the
394 vestigial RA needed to go alongside IPv6. Is picks up
395 configuration from the DHCPv6 conf, and should just need
396 enabling with --enable-ra.
398 Fix long-standing wrinkle with --localise-queries that
399 could result in wrong answers when DNS packets arrive
400 via an interface other than the expected one. Thanks to
401 Lorenzo Milesi and John Hanks for spotting this one.
403 Update French translation. Thanks to Gildas Le Nadan.
405 Update Polish translation. Thanks to Jan Psota.
409 Fix regression in 2.58 which caused failure to start up
410 with some combinations of dnsmasq config and IPv6 kernel
411 network config. Thanks to Brielle Bruns for the bug
414 Improve dnsmasq's behaviour when network interfaces are
415 still doing duplicate address detection (DAD). Previously,
416 dnsmasq would wait up to 20 seconds at start-up for the
417 DAD state to terminate. This is broken for bridge
418 interfaces on recent Linux kernels, which don't start DAD
419 until the bridge comes up, and so can take arbitrary
420 time. The new behaviour lets dnsmasq poll for an arbitrary
421 time whilst providing service on other interfaces. Thanks
422 to Stephen Hemminger for pointing out the problem.
426 Provide a definition of the SA_SIZE macro where it's
427 missing. Fixes build failure on openBSD.
429 Don't include a zero terminator at the end of messages
430 sent to /dev/log when /dev/log is a datagram socket.
431 Thanks to Didier Rabound for spotting the problem.
433 Add --dhcp-sequential-ip flag, to force allocation of IP
434 addresses in ascending order. Note that the default
435 pseudo-random mode is in general better but some
436 server-deployment applications need this.
438 Fix problem where a server-id of 0.0.0.0 is sent to a
439 client when a dhcp-relay is in use if a client renews a
440 lease after dnsmasq restart and before any clients on the
441 subnet get a new lease. Thanks to Mike Ruiz for assistance
442 in chasing this one down.
444 Don't return NXDOMAIN to an AAAA query if we have CNAME
445 which points to an A record only: NODATA is the correct
446 reply in this case. Thanks to Tom Fernandes for spotting
449 Relax the need to supply a netmask in --dhcp-range for
450 networks which use a DHCP relay. Whilst this is still
451 desireable, in the absence of a netmask dnsmasq will use
452 a default based on the class (A, B, or C) of the address.
453 This should at least remove a cause of mysterious failure
454 for people using RFC1918 addresses and relays.
456 Add support for Linux conntrack connection marking. If
457 enabled with --conntrack, the connection mark for incoming
458 DNS queries will be copied to the outgoing connections
459 used to answer those queries. This allows clever firewall
460 and accounting stuff. Only available if dnsmasq is
461 compiled with HAVE_CONNTRACK and adds a dependency on
462 libnetfilter-conntrack. Thanks to Ed Wildgoose for the
463 initial idea, testing and sponsorship of this function.
465 Provide a sane error message when someone attempts to
466 match a tag in --dhcp-host.
468 Tweak the behaviour of --domain-needed, to avoid problems
469 with recursive nameservers downstream of dnsmasq. The new
470 behaviour only stops A and AAAA queries, and returns
471 NODATA rather than NXDOMAIN replies.
473 Efficiency fix for very large DHCP configurations, thanks
474 to James Gartrell and Mike Ruiz for help with this.
476 Allow the TFTP-server address in --dhcp-boot to be a
477 domain-name which is looked up in /etc/hosts. This can
478 give multiple IP addresses which are used round-robin,
479 thus doing TFTP server load-balancing. Thanks to Sushil
480 Agrawal for the patch.
482 When two tagged dhcp-options for a particular option
483 number are both valid, use the one which is valid without
484 a tag from the dhcp-range. Allows overriding of the value
485 of a DHCP option for a particular host as well as
486 per-network values. So
487 --dhcp-range=set:interface1,......
488 --dhcp-host=set:myhost,.....
489 --dhcp-option=tag:interface1,option:nis-domain,"domain1"
490 --dhcp-option=tag:myhost,option:nis-domain,"domain2"
491 will set the NIS-domain to domain1 for hosts in the range, but
492 override that to domain2 for a particular host.
494 Fix bug which resulted in truncated files and timeouts for
495 some TFTP transfers. The bug only occurs with netascii
496 transfers and needs an unfortunate relationship between
497 file size, blocksize and the number of newlines in the
498 last block before it manifests itself. Many thanks to
499 Alkis Georgopoulos for spotting the problem and providing
500 a comprehensive test-case.
502 Fix regression in TFTP server on *BSD platforms introduced
503 in version 2.56, due to confusion with sockaddr
504 length. Many thanks to Loic Pefferkorn for finding this.
506 Support scope-ids in IPv6 addresses of nameservers from
507 /etc/resolv.conf and in --server options. Eg
508 nameserver fe80::202:a412:4512:7bbf%eth0 or
509 server=fe80::202:a412:4512:7bbf%eth0. Thanks to
510 Michael Stapelberg for the suggestion.
512 Update Polish translation, thanks to Jan Psota.
514 Update French translation. Thanks to Gildas Le Nadan.
518 Add patches to allow build under Android.
520 Provide our own header for the DNS protocol, rather than
521 relying on arpa/nameser.h. This has proved more or less
522 defective over the years and the final straw is that it's
523 effectively empty on Android.
525 Fix regression in 2.56 which caused hex constants in
526 configuration to be rejected if they contain the '*'
529 Correct wrong casts of arguments to ctype.h functions,
530 isdigit(), isxdigit() etc. Thanks to Matthias Andree for
533 Allow build with IDN support independently from i18n.
534 IDN support continues to be included automatically
535 when i18n is included.
536 'make COPTS=-DHAVE_IDN' is the magic incantation.
538 Modify check on extraneous command line junk (added in
539 2.56) so that it doesn't complain about extra _empty_
540 arguments. Otherwise this breaks libvirt.
544 Add a patch to allow dnsmasq to get interface names right in a
545 Solaris zone. Thanks to Dj Padzensky for this.
547 Improve data-type parsing heuristics so that
548 --dhcp-option=option:domain-search,.
549 treats the value as a string and not an IP address.
550 Thanks to Clemens Fischer for spotting that.
552 Add IPv6 support to the TFTP server. Many thanks to Jan
553 'RedBully' Seiffert for the patches.
555 Log DNS queries at level LOG_INFO, rather then
556 LOG_DEBUG. This makes things consistent with DHCP
557 logging. Thanks to Adam Pribyl for spotting the problem.
559 Ensure that dnsmasq terminates cleanly when using
560 --syslog-async even if it cannot make a connection to the
563 Add --add-mac option. This is to support currently
564 experimental DNS filtering facilities. Thanks to Benjamin
565 Petrin for the orignal patch.
567 Fix bug which meant that tags were ignored in dhcp-range
568 configuration specifying PXE-proxy service. Thanks to
569 Cristiano Cumer for spotting this.
571 Raise an error if there is extra junk, not part of an
572 option, on the command line.
574 Flag a couple of log messages in cache.c as coming from
575 the DHCP subsystem. Thanks to Olaf Westrik for the patch.
577 Omit timestamps from logs when a) logging to stderr and
578 b) --keep-in-forground is set. The logging facility on the
579 other end of stderr can be assumned to supply them. Thanks
580 to John Hallam for the patch.
582 Don't complain about strings longer than 255 characters in
583 --txt-record, just split the long strings into 255
584 character chunks instead.
586 Fix crash on double-free. This bug can only happen when
587 dhcp-script is in use and then only in rare circumstances
588 triggered by high DHCP transaction rate and a slow
589 script. Thanks to Ferenc Wagner for finding the problem.
591 Only log that a file has been sent by TFTP after the
592 transfer has completed succesfully.
594 A good suggestion from Ferenc Wagner: extend
595 the --domain option to allow this sort of thing:
596 --domain=thekelleys.org.uk,192.168.0.0/24,local
597 which automatically creates
598 --local=/thekelleys.org.uk/
599 --local=/0.168.192.in-addr.arpa/
601 Tighten up syntax checking of hex contants in the config
602 file. Thanks to Fred Damen for spotting this.
604 Add dnsmasq logo/icon, contributed by Justin Swift. Many
607 Never cache DNS replies which have the 'cd' bit set, or
608 which result from queries forwarded with the 'cd' bit
609 set. The 'cd' bit instructs a DNSSEC validating server
610 upstream to ignore signature failures and return replies
611 anyway. Without this change it's possible to pollute the
612 dnsmasq cache with bad data by making a query with the
613 'cd' bit set and subsequent queries would return this data
614 without its being marked as suspect. Thanks to Anders
615 Kaseorg for pointing out this problem.
617 Add --proxy-dnssec flag, for compliance with RFC
618 4035. Dnsmasq will now clear the 'ad' bit in answers returned
619 from upstream validating nameservers unless this option is
622 Allow a filename of "-" for --conf-file to read
623 stdin. Suggestion from Timothy Redaelli.
625 Rotate the order of SRV records in replies, to provide
626 round-robin load balancing when all the priorities are
627 equal. Thanks to Peter McKinney for the suggestion.
630 contrib/MacOSX-launchd/uk.org.thekelleys.dnsmasq.plist
631 so that it doesn't log all queries to a file by
632 default. Thanks again to Peter McKinney.
634 By default, setting an IPv4 address for a domain but not
635 an IPv6 address causes dnsmasq to return
636 an NODATA reply for IPv6 (or vice-versa). So
637 --address=/google.com/1.2.3.4 stops IPv6 queries for
638 *google.com from being forwarded. Make it possible to
639 override this behaviour by defining the sematics if the
640 same domain appears in both --server and --address.
641 In that case, the --address has priority for the address
642 family in which is appears, but the --server has priority
643 of the address family which doesn't appear in --adddress
645 --address=/google.com/1.2.3.4
646 --server=/google.com/#
647 will return 1.2.3.4 for IPv4 queries for *.google.com but
648 forward IPv6 queries to the normal upstream nameserver.
649 Similarly when setting an IPv6 address
650 only this will allow forwarding of IPv4 queries. Thanks to
651 William for pointing out the need for this.
653 Allow more than one --dhcp-optsfile and --dhcp-hostsfile
654 and make them understand directories as arguments in the
655 same way as --addn-hosts. Suggestion from John Hanks.
657 Ignore rebinding requests for leases we don't know
658 about. Rebind is broadcast, so we might get to overhear a
659 request meant for another DHCP server. NAKing this is
660 wrong. Thanks to Brad D'Hondt for assistance with this.
662 Fix cosmetic bug which produced strange output when
663 dumping cache statistics with some configurations. Thanks
664 to Fedor Kozhevnikov for spotting this.
668 Fix crash when /etc/ethers is in use. Thanks to
669 Gianluigi Tiesi for finding this.
671 Fix crash in netlink_multicast(). Thanks to Arno Wald for
674 Allow the empty domain "." in dhcp domain-search (119)
679 There is no version 2.54 to avoid confusion with 2.53,
680 which incorrectly identifies itself as 2.54.
684 Fix failure to compile on Debian/kFreeBSD. Thanks to
685 Axel Beckert and Petr Salinger.
687 Fix code to avoid scary strict-aliasing warnings
688 generated by gcc 4.4.
690 Added FAQ entry warning about DHCP failures with Vista
691 when firewalls block 255.255.255.255.
693 Fixed bug which caused bad things to happen if a
694 resolv.conf file which exists is subsequently removed.
695 Thanks to Nikolai Saoukh for the patch.
697 Rationalised the DHCP tag system. Every configuration item
698 which can set a tag does so by adding "set:<tag>" and
699 every configuration item which is conditional on a tag is
700 made so by "tag:<tag>". The NOT operator changes to '!',
701 which is a bit more intuitive too. Dhcp-host directives
702 can set more than one tag now. The old '#' NOT,
703 "net:" prefix and no-prefixes are still honoured, so
704 no existing config file needs to be changed, but
705 the documentation and new-style config files should be
708 Added --tag-if to allow boolean operations on tags.
709 This allows complicated logic to be clearer and more
710 general. A great suggestion from Richard Voigt.
712 Add broadcast/unicast information to DHCP logging.
714 Allow --dhcp-broadcast to be unconditional.
716 Fixed incorrect behaviour with NOT <tag> conditionals in
717 dhcp-options. Thanks to Max Turkewitz for assistance
720 If we send vendor-class encapsulated options based on the
721 vendor-class supplied by the client, and no explicit
722 vendor-class option is given, echo back the vendor-class
725 Fix bug which stopped dnsmasq from matching both a
726 circuitid and a remoteid. Thanks to Ignacio Bravo for
729 Add --dhcp-proxy, which makes it possible to configure
730 dnsmasq to use a DHCP relay agent as a full proxy, with
731 all DHCP messages passing through the proxy. This is
732 useful if the relay adds extra information to the packets
733 it forwards, but cannot be configured with the RFC 5107
734 server-override option.
736 Added interface:<iface name> part to dhcp-range. The
737 semantics of this are very odd at first sight, but it
738 allows a single line of the form
739 dhcp-range=interface:virt0,192.168.0.4,192.168.0.200
740 to be added to dnsmasq configuration which then supplies
741 DHCP and DNS services to that interface, without affecting
742 what services are supplied to other interfaces and
743 irrespective of the existance or lack of
744 interface=<interface>
745 lines elsewhere in the dnsmasq configuration. The idea is
746 that such a line can be added automatically by libvirt
747 or equivalent systems, without disturbing any manual
750 Similarly to the above, allow --enable-tftp=<interface>
752 Allow a TFTP root to be set separately for requests via
753 different interfaces, --tftp-root=<path>,<interface>
755 Correctly handle and log clashes between CNAMES and
756 DNS names being given to DHCP leases. This fixes a bug
757 which caused nonsense IP addresses to be logged. Thanks to
758 Sergei Zhirikov for finding and analysing the problem.
760 Tweak flush_log so as to avoid leaving the log
761 file in non-blocking mode. O_NONBLOCK is a property of the
762 file, not the process/descriptor.
764 Fix contrib/Solaris10/create_package
765 (/usr/man -> /usr/share/man) Thanks to Vita Batrla.
767 Fix a problem where, if a client got a lease, then went
768 to another subnet and got another lease, then moved back,
769 it couldn't resume the old lease, but would instead get
770 a new address. Thanks to Leonardo Rodrigues for spotting
771 this and testing the fix.
773 Fix weird bug which sometimes omitted certain characters
774 from the start of quoted strings in dhcp-options. Thanks
775 to Dayton Turner for spotting the problem.
777 Add facility to redirect some domains to the standard
778 upstream servers: this allows something like
779 --server=/google.com/1.2.3.4 --server=/www.google.com/#
780 which will send queries for *.google.com to 1.2.3.4,
781 except *www.google.com which will be forwarded as usual.
782 Thanks to AJ Weber for prompting this addition.
784 Improve the hash-algorithm used to generate IP addresses
785 from MAC addresses during initial DHCP address
786 allocation. This improves performance when large numbers
787 of hosts with similar MAC addresses all try and get an IP
788 address at the same time. Thanks to Paul Smith for his
791 Tweak DHCP code so that --bridge-interface can be used to
792 select which IP alias of an interface should be used for
793 DHCP purposes on Linux. If eth0 has an alias eth0:dhcp
794 then adding --bridge-interface=eth0:dhcp,eth0 will use
795 the address of eth0:dhcp to determine the correct subnet
796 for DHCP address allocation. Thanks to Pawel Golaszewski
797 for prompting this and Eric Cooper for further testing.
799 Add --dhcp-generate-names. Suggestion by Ferenc Wagner.
801 Tweak DNS server selection algorithm when there is more
802 than one server available for a domain, eg.
803 --server=/mydomain/1.1.1.1
804 --server=/mydomain/2.2.2.2
805 Thanks to Alberto Cuesta-Canada for spotting a weakness
808 Add --max-ttl. Thanks to Fredrik Ringertz for the patch.
810 Allow --log-facility=- to force all logging to
811 stderr. Suggestion from Clemens Fischer.
813 Fix regression which caused configuration like
814 --address=/.domain.com/1.2.3.4 to be rejected. The dot to the
815 left of the domain has been implied and not required for a
816 long time, but it should be accepted for backward
817 compatibility. Thanks to Andrew Burcin for spotting this.
819 Add --rebind-domain-ok and --rebind-localhost-ok.
820 Suggestion from Clemens Fischer.
822 Log replies to queries of type TXT, when --log-queries
825 Fix compiler warnings when compiled with -DNO_DHCP. Thanks
826 to Shantanu Gadgil for the patch.
828 Updated French translation. Thanks to Gildas Le Nadan.
830 Updated Polish translation. Thanks to Jan Psota.
832 Updated German translation. Thanks to Matthias Andree.
834 Added contrib/static-arp, thanks to Darren Hoo.
836 Fix corruption of the domain when a name from /etc/hosts
837 overrides one supplied by a DHCP client. Thanks to Fedor
838 Kozhevnikov for spotting the problem.
840 Updated Spanish translation. Thanks to Chris Chatham.
844 Work around a Linux kernel bug which insists that the
845 length of the option passed to setsockopt must be at least
846 sizeof(int) bytes, even if we're calling SO_BINDTODEVICE
847 and the device name is "lo". Note that this is fixed
848 in kernel 2.6.31, but the workaround is harmless and
849 allows earlier kernels to be used. Also fix dnsmasq
850 bug which reported the wrong address when this failed.
851 Thanks to Fedor for finding this.
853 The API for IPv6 PKTINFO changed around Linux kernel
854 2.6.14. Workaround the case where dnsmasq is compiled
855 against newer headers, but then run on an old kernel:
856 necessary for some *WRT distros.
858 Re-read the set of network interfaces when re-loading
859 /etc/resolv.conf if --bind-interfaces is not set. This
860 handles the case that loopback interfaces do not exist
861 when dnsmasq is first started.
863 Tweak the PXE code to support port 4011. This should
864 reduce broadcasts and make things more reliable when other
865 servers are around. It also improves inter-operability
866 with certain clients.
868 Make a pxe-service configuration with no filename or boot
869 service type legal: this does a local boot. eg.
870 pxe-service=x86PC, "Local boot"
872 Be more conservative in detecting "A for A"
873 queries. Dnsmasq checks if the name in a type=A query looks
874 like a dotted-quad IP address and answers the query itself
875 if so, rather than forwarding it. Previously dnsmasq
876 relied in the library function inet_addr() to convert
877 addresses, and that will accept some things which are
878 confusing in this context, like 1.2.3 or even just
879 1234. Now we only do A for A processing for four decimal
880 numbers delimited by dots.
882 A couple of tweaks to fix compilation on Solaris. Thanks
883 to Joel Macklow for help with this.
885 Another Solaris compilation tweak, needed for Solaris
886 2009.06. Thanks to Lee Essen for that.
888 Added extract packaging stuff from Lee Essen to
891 Increased the default limit on number of leases to 1000
892 (from 150). This is mainly a defence against DoS attacks,
893 and for the average "one for two class C networks"
894 installation, IP address exhaustion does that just as
895 well. Making the limit greater than the number of IP
896 addresses available in such an installation removes a
897 surprise which otherwise can catch people out.
899 Removed extraneous trailing space in the value of the
900 DNSMASQ_TIME_REMAINING DNSMASQ_LEASE_LENGTH and
901 DNSMASQ_LEASE_EXPIRES environment variables. Thanks to
902 Gildas Le Nadan for spotting this.
904 Provide the network-id tags for a DHCP transaction to
905 the lease-change script in the environment variable
906 DNSMASQ_TAGS. A good suggestion from Gildas Le Nadan.
908 Add support for RFC3925 "Vendor-Identifying Vendor
909 Options". The syntax looks like this:
910 --dhcp-option=vi-encap:<enterprise number>, .........
912 Add support to --dhcp-match to allow matching against
913 RFC3925 "Vendor-Identifying Vendor Classes". The syntax
915 --dhcp-match=tag,vi-encap<enterprise number>, <value>
917 Add some application specific code to assist in
918 implementing the Broadband forum TR069 CPE-WAN
919 specification. The details are in contrib/CPE-WAN/README
921 Increase the default DNS packet size limit to 4096, as
922 recommended by RFC5625 section 4.4.3. This can be
923 reconfigured using --edns-packet-max if needed. Thanks to
924 Francis Dupont for pointing this out.
926 Rewrite query-ids even for TSIG signed packets, since
927 this is allowed by RFC5625 section 4.5.
929 Use getopt_long by default on OS X. It has been supported
930 since version 10.3.0. Thanks to Arek Dreyer for spotting
933 Added up-to-date startup configuration for MacOSX/launchd
934 in contrib/MacOSX-launchd. Thanks to Arek Dreyer for
937 Fix link error when including Dbus but excluding DHCP.
938 Thanks to Oschtan for the bug report.
940 Updated French translation. Thanks to Gildas Le Nadan.
942 Updated Polish translation. Thanks to Jan Psota.
944 Updated Spanish translation. Thanks to Chris Chatham.
946 Fixed confusion about domains, when looking up DHCP hosts
947 in /etc/hosts. This could cause spurious "Ignoring
948 domain..." messages. Thanks to Fedor Kozhevnikov for
949 finding and analysing the problem.
953 Add support for internationalised DNS. Non-ASCII characters
954 in domain names found in /etc/hosts, /etc/ethers and
955 /etc/dnsmasq.conf will be correctly handled by translation to
956 punycode, as specified in RFC3490. This function is only
957 available if dnsmasq is compiled with internationalisation
958 support, and adds a dependency on GNU libidn. Without i18n
959 support, dnsmasq continues to be compilable with just
960 standard tools. Thanks to Yves Dorfsman for the
963 Add two more environment variables for lease-change scripts:
964 First, DNSMASQ_SUPPLIED_HOSTNAME; this is set to the hostname
965 supplied by a client, even if the actual hostname used is
966 over-ridden by dhcp-host or dhcp-ignore-names directives.
967 Also DNSMASQ_RELAY_ADDRESS which gives the address of
968 a DHCP relay, if used.
969 Suggestions from Michael Rack.
971 Fix regression which broke echo of relay-agent
972 options. Thanks to Michael Rack for spotting this.
974 Don't treat option 67 as being interchangeable with
975 dhcp-boot parameters if it's specified as
978 Make the code to call scripts on lease-change compile-time
979 optional. It can be switched off by editing src/config.h
980 or building with "make COPTS=-DNO_SCRIPT".
982 Make the TFTP server cope with filenames from Windows/DOS
983 which use '\' as pathname separator. Thanks to Ralf for
986 Updated Polish translation. Thanks to Jan Psota.
988 Warn if an IP address is duplicated in /etc/ethers. Thanks
989 to Felix Schwarz for pointing this out.
991 Teach --conf-dir to take an option list of file suffices
992 which will be ignored when scanning the directory. Useful
993 for backup files etc. Thanks to Helmut Hullen for the
996 Add new DHCP option named tftpserver-address, which
997 corresponds to the third argument of dhcp-boot. This
998 allows the complete functionality of dhcp-boot to be
999 replicated with dhcp-option. Useful when using
1002 Test which upstream nameserver to use every 10 seconds
1003 or 50 queries and not just when a query times out and
1004 is retried. This should improve performance when there
1005 is a slow nameserver in the list. Thanks to Joe for the
1008 Don't do any PXE processing, even for clients with the
1009 correct vendorclass, unless at least one pxe-prompt or
1010 pxe-service option is given. This stops dnsmasq
1011 interfering with proxy PXE subsystems when it is just
1012 the DHCP server. Thanks to Spencer Clark for spotting this.
1014 Limit the blocksize used for TFTP transfers to a value
1015 which avoids packet fragmentation, based on the MTU of the
1016 local interface. Many netboot ROMs can't cope with
1019 Honour dhcp-ignore configuration for PXE and proxy-PXE
1020 requests. Thanks to Niels Basjes for the bug report.
1022 Updated French translation. Thanks to Gildas Le Nadan.
1026 Fix security problem which allowed any host permitted to
1027 do TFTP to possibly compromise dnsmasq by remote buffer
1028 overflow when TFTP enabled. Thanks to Core Security
1029 Technologies and Iván Arce, Pablo Hernán Jorge, Alejandro
1030 Pablo Rodriguez, Martín Coco, Alberto Soliño Testa and
1031 Pablo Annetta. This problem has Bugtraq id: 36121
1034 Fix a problem which allowed a malicious TFTP client to
1035 crash dnsmasq. Thanks to Steve Grubb at Red Hat for
1036 spotting this. This problem has Bugtraq id: 36120 and
1041 Fix regression in 2.48 which disables the lease-change
1042 script. Thanks to Jose Luis Duran for spotting this.
1044 Log TFTP "file not found" errors. These were not logged,
1045 since a normal PXELinux boot generates many of them, but
1046 the lack of the messages seems to be more confusing than
1047 routinely seeing them when there is no real error.
1049 Update Spanish translation. Thanks to Chris Chatham.
1053 Archived the extensive, backwards, changelog to
1054 CHANGELOG.archive. The current changelog now runs from
1055 version 2.43 and runs conventionally.
1057 Fixed bug which broke binding of servers to physical
1058 interfaces when interface names were longer than four
1059 characters. Thanks to MURASE Katsunori for the patch.
1061 Fixed netlink code to check that messages come from the
1062 correct source, and not another userspace process. Thanks
1063 to Steve Grubb for the patch.
1065 Maintainability drive: removed bug and missing feature
1066 workarounds for some old platforms. Solaris 9, OpenBSD
1067 older than 4.1, Glibc older than 2.2, Linux 2.2.x and
1068 DBus older than 1.1.x are no longer supported.
1070 Don't read included configuration files more than once:
1071 allows complex configuration structures without problems.
1073 Mark log messages from the various subsystems in dnsmasq:
1074 messages from the DHCP subsystem now have the ident string
1075 "dnsmasq-dhcp" and messages from TFTP have ident
1076 "dnsmasq-tftp". Thanks to Olaf Westrik for the patch.
1078 Fix possible infinite DHCP protocol loop when an IP
1079 address nailed to a hostname (not a MAC address) and a
1080 host sometimes provides the name, sometimes not.
1082 Allow --addn-hosts to take a directory: all the files
1083 in the directory are read. Thanks to Phil Cornelius for
1086 Support --bridge-interface on all platforms, not just BSD.
1088 Added support for advanced PXE functions. It's now
1089 possible to define a prompt and menu options which will
1090 be displayed when a client PXE boots. It's also possible to
1091 hand-off booting to other boot servers. Proxy-DHCP, where
1092 dnsmasq just supplies the PXE information and another DHCP
1093 server does address allocation, is also allowed. See the
1094 --pxe-prompt and --pxe-service keywords. Thanks to
1095 Alkis Georgopoulos for the suggestion and Guilherme Moro
1096 and Michael Brown for assistance.
1098 Improvements to DHCP logging. Thanks to Tom Metro for
1101 Add ability to build dnsmasq without DHCP support. To do
1102 this, edit src/config.h or build with
1103 "make COPTS=-DNO_DHCP". Thanks to Mahavir Jain for the patch.
1105 Added --test command-line switch - syntax check
1106 configuration files only.
1108 Updated French translation. Thanks to Gildas Le Nadan.
1112 Updated French translation. Thanks to Gildas Le Nadan.
1114 Fixed interface enumeration code to work on NetBSD
1115 5.0. Thanks to Roy Marples for the patch.
1117 Updated config.h to use the same location for the lease
1118 file on NetBSD as the other *BSD variants. Also allow
1119 LEASEFILE and CONFFILE symbols to be overriden in CFLAGS.
1121 Handle duplicate address detection on IPv6 more
1122 intelligently. In IPv6, an interface can have an address
1123 which is not usable, because it is still undergoing DAD
1124 (such addresses are marked "tentative"). Attempting to
1125 bind to an address in this state returns an error,
1126 EADDRNOTAVAIL. Previously, on getting such an error,
1127 dnsmasq would silently abandon the address, and never
1128 listen on it. Now, it retries once per second for 20
1129 seconds before generating a fatal error. 20 seconds should
1130 be long enough for any DAD process to complete, but can be
1131 adjusted in src/config.h if necessary. Thanks to Martin
1132 Krafft for the bug report.
1134 Add DBus introspection. Patch from Jeremy Laine.
1136 Update Dbus configuration file. Patch from Colin Walters.
1138 http://bugs.freedesktop.org/show_bug.cgi?id=18961
1140 Support arbitrarily encapsulated DHCP options, suggestion
1141 and initial patch from Samium Gromoff. This is useful for
1142 (eg) gPXE, which expect all its private options to be
1143 encapsulated inside a single option 175. So, eg,
1145 dhcp-option = encap:175, 190, "iscsi-client0"
1146 dhcp-option = encap:175, 191, "iscsi-client0-secret"
1148 will provide iSCSI parameters to gPXE.
1150 Enhance --dhcp-match to allow testing of the contents of a
1151 client-sent option, as well as its presence. This
1152 application in mind for this is RFC 4578
1153 client-architecture specifiers, but it's generally useful.
1154 Joey Korkames suggested the enhancement.
1156 Move from using the IP_XMIT_IF ioctl to IP_BOUND_IF on
1157 OpenSolaris. Thanks to Bastian Machek for the heads-up.
1159 No longer complain about blank lines in
1160 /etc/ethers. Thanks to Jon Nelson for the patch.
1162 Fix binding of servers to physical devices, eg
1163 --server=/domain/1.2.3.4@eth0 which was broken from 2.43
1164 onwards unless --query-port=0 set. Thanks to Peter Naulls
1167 Reply to DHCPINFORM requests even when the supplied ciaddr
1168 doesn't fall in any dhcp-range. In this case it's not
1169 possible to supply a complete configuration, but
1170 individually-configured options (eg PAC) may be useful.
1172 Allow the source address of an alias to be a range:
1173 --alias=192.168.0.0,10.0.0.0,255.255.255.0 maps the whole
1174 subnet 192.168.0.0->192.168.0.255 to 10.0.0.0->10.0.0.255,
1176 --alias=192.168.0.10-192.168.0.40,10.0.0.0,255.255.255.0
1177 maps only the 192.168.0.10->192.168.0.40 region. Thanks to
1178 Ib Uhrskov for the suggestion.
1180 Don't dynamically allocate DHCP addresses which may break
1181 Windows. Addresses which end in .255 or .0 are broken in
1182 Windows even when using supernetting.
1183 --dhcp-range=192.168.0.1,192.168.1.254,255,255,254.0 means
1184 192.168.0.255 is a valid IP address, but not for Windows.
1185 See Microsoft KB281579. We therefore no longer allocate
1186 these addresses to avoid hard-to-diagnose problems.
1188 Update Polish translation. Thanks to Jan Psota.
1190 Delete the PID-file when dnsmasq shuts down. Note that by
1191 this time, dnsmasq is normally not running as root, so
1192 this will fail if the PID-file is stored in a root-owned
1193 directory; such failure is silently ignored. To take
1194 advantage of this feature, the PID-file must be stored in a
1195 directory owned and write-able by the user running
1200 Allow --bootp-dynamic to take a netid tag, so that it may
1201 be selectively enabled. Thanks to Olaf Westrik for the
1204 Remove ISC-leasefile reading code. This has been
1205 deprecated for a long time, and last time I removed it, it
1206 ended up going back by request of one user. This time,
1207 it's gone for good; otherwise it would need to be
1208 re-worked to support multiple domains (see below).
1210 Support DHCP clients in multiple DNS domains. This is a
1211 long-standing request. Clients are assigned to a domain
1212 based in their IP address.
1214 Add --dhcp-fqdn flag, which changes behaviour if DNS names
1215 assigned to DHCP clients. When this is set, there must be
1216 a domain associated with each client, and only
1217 fully-qualified domain names are added to the DNS. The
1218 advantage is that the only the FQDN needs to be unique,
1219 so that two or more DHCP clients can share a hostname, as
1220 long as they are in different domains.
1222 Set environment variable DNSMASQ_DOMAIN when invoking
1223 lease-change script. This may be useful information to
1224 have now that it's variable.
1226 Tighten up data-checking code for DNS packet
1227 handling. Thanks to Steve Dodd who found certain illegal
1228 packets which could crash dnsmasq. No memory overwrite was
1229 possible, so this is not a security issue beyond the DoS
1232 Update example config dhcp option 47, the previous
1233 suggestion generated an illegal, zero-length,
1234 option. Thanks to Matthias Andree for finding this.
1236 Rewrite hosts-file reading code to remove the limit of
1237 1024 characters per line. John C Meuser found this.
1239 Create a net-id tag with the name of the interface on
1240 which the DHCP request was received.
1242 Fixed minor memory leak in DBus code, thanks to Jeremy
1243 Laine for the patch.
1245 Emit DBus signals as the DHCP lease database
1246 changes. Thanks to Jeremy Laine for the patch.
1248 Allow for more that one MAC address in a dhcp-host
1249 line. This configuration tells dnsmasq that it's OK to
1250 abandon a DHCP lease of the fixed address to one MAC
1251 address, if another MAC address in the dhcp-host statement
1252 asks for an address. This is useful to give a fixed
1253 address to a host which has two network interfaces
1254 (say, a laptop with wired and wireless interfaces.)
1255 It's very important to ensure that only one interface
1256 at a time is up, since dnsmasq abandons the first lease
1257 and re-uses the address before the leased time has
1258 elapsed. John Gray suggested this.
1260 Tweak the response to a DHCP request packet with a wrong
1261 server-id when --dhcp-authoritative is set; dnsmasq now
1262 returns a DHCPNAK, rather than silently ignoring the
1263 packet. Thanks to Chris Marget for spotting this
1266 Add --cname option. This provides a limited alias
1267 function, usable for DHCP names. Thanks to AJ Weber for
1268 suggestions on this.
1270 Updated contrib/webmin with latest version from Neil
1273 Updated Polish translation. Thanks to Jan Psota.
1275 Correct the text names for DHCP options 64 and 65 to be
1276 "nis+-domain" and "nis+-servers".
1278 Updated Spanish translation. Thanks to Chris Chatham.
1280 Force re-reading of /etc/resolv.conf when an "interface
1285 Fix total DNS failure in release 2.44 unless --min-port
1286 specified. Thanks to Steven Barth and Grant Coady for
1287 bugreport. Also reject out-of-range port spec, which could
1288 break things too: suggestion from Gilles Espinasse.
1292 Fix crash when unknown client attempts to renew a DHCP
1293 lease, problem introduced in version 2.43. Thanks to
1294 Carlos Carvalho for help chasing this down.
1296 Fix potential crash when a host which doesn't have a lease
1297 does DHCPINFORM. Again introduced in 2.43. This bug has
1298 never been reported in the wild.
1300 Fix crash in netlink code introduced in 2.43. Thanks to
1301 Jean Wolter for finding this.
1303 Change implementation of min_port to work even if min-port
1306 Patch to enable compilation of latest Mac OS X. Thanks to
1309 Update Spanish translation. Thanks to Christopher Chatham.
1313 Updated Polish translation. Thanks to Jan Psota.
1315 Flag errors when configuration options are repeated
1318 Further tweaks for GNU/kFreeBSD
1320 Add --no-wrap to msgmerge call - provides nicer .po file
1323 Honour lease-time spec in dhcp-host lines even for
1324 BOOTP. The user is assumed to known what they are doing in
1325 this case. (Hosts without the time spec still get infinite
1326 leases for BOOTP, over-riding the default in the
1327 dhcp-range.) Thanks to Peter Katzmann for uncovering this.
1329 Fix problem matching relay-agent ids. Thanks to Michael
1330 Rack for the bug report.
1332 Add --naptr-record option. Suggestion from Johan
1335 Implement RFC 5107 server-id-override DHCP relay agent
1338 Apply patches from Stefan Kruger for compilation on
1339 Solaris 10 under Sun studio.
1341 Yet more tweaking of Linux capability code, to suppress
1342 pointless wingeing from kernel 2.6.25 and above.
1344 Improve error checking during startup. Previously, some
1345 errors which occurred during startup would be worked
1346 around, with dnsmasq still starting up. Some were logged,
1347 some silent. Now, they all cause a fatal error and dnsmasq
1348 terminates with a non-zero exit code. The errors are those
1349 associated with changing uid and gid, setting process
1350 capabilities and writing the pidfile. Thanks to Uwe
1351 Gansert and the Suse security team for pointing out
1352 this improvement, and Bill Reimers for good implementation
1355 Provide NO_LARGEFILE compile option to switch off largefile
1356 support when compiling against versions of uclibc which
1357 don't support it. Thanks to Stephane Billiart for the patch.
1359 Implement random source ports for interactions with
1360 upstream nameservers. New spoofing attacks have been found
1361 against nameservers which do not do this, though it is not
1362 clear if dnsmasq is vulnerable, since to doesn't implement
1363 recursion. By default dnsmasq will now use a different
1364 source port (and socket) for each query it sends
1365 upstream. This behaviour can suppressed using the
1366 --query-port option, and the old default behaviour
1367 restored using --query-port=0. Explicit source-port
1368 specifications in --server configs are still honoured.
1370 Replace the random number generator, for better
1371 security. On most BSD systems, dnsmasq uses the
1372 arc4random() RNG, which is secure, but on other platforms,
1373 it relied on the C-library RNG, which may be
1374 guessable and therefore allow spoofing. This release
1375 replaces the libc RNG with the SURF RNG, from Daniel
1376 J. Berstein's DJBDNS package.
1378 Don't attempt to change user or group or set capabilities
1379 if dnsmasq is run as a non-root user. Without this, the
1380 change from soft to hard errors when these fail causes
1381 problems for non-root daemons listening on high
1382 ports. Thanks to Patrick McLean for spotting this.
1384 Updated French translation. Thanks to Gildas Le Nadan.
1388 The changelog for version 2.42 and earlier is
1389 available in CHANGELOG.archive.
