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 correponding 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
51 Fix regression which broke forwarding of queries sent via
52 TCP which are not for A and AAAA and which were directed to
53 non-default servers. Thanks to Niax for the bug report.
55 Fix failure to build with DHCP support excluded. Thanks to
56 Gustavo Zacarias for the patch.
58 Fix nasty regression in 2.64 which completely broke cacheing.
62 Handle DHCP FQDN options with all flag bits zero and
63 --dhcp-client-update set. Thanks to Bernd Krumbroeck for
66 Finesse the check for /etc/hosts names which conflict with
67 DHCP names. Previously a name/address pair in /etc/hosts
68 which didn't match the name/address of a DHCP lease would
69 generate a warning. Now that only happesn if there is not
70 also a match. This allows multiple addresses for a name in
71 /etc/hosts with one of them assigned via DHCP.
73 Fix broken vendor-option processing for BOOTP. Thanks to
74 Hans-Joachim Baader for the bug report.
76 Don't report spurious netlink errors, regression in
77 2.63. Thanks to Vladislav Grishenko for the patch.
79 Flag DHCP or DHCPv6 in starup logging. Thanks to
80 Vladislav Grishenko for the patch.
82 Add SetServersEx method in DBus interface. Thanks to Dan
83 Williams for the patch.
85 Add SetDomainServers method in DBus interface. Thanks to
86 Roy Marples for the patch.
88 Fix build with later Lua libraries. Thansk to Cristian
89 Rodriguez for the patch.
91 Add --max-cache-ttl option. Thanks to Dennis Kaarsemaker
94 Fix breakage of --host-record parsing, resulting in
95 infinte loop at startup. Regression in 2.63. Thanks to
96 Haim Gelfenbeyn for spotting this.
98 Set SO_REUSEADDRESS and SO_V6ONLY options on the DHCPv6
99 socket, this allows multiple instances of dnsmasq on a
100 single machine, in the same way as for DHCPv4. Thanks to
101 Gene Czarcinski and Vladislav Grishenko for work on this.
103 Fix DHCPv6 to do access control correctly when it's
104 configured with --listen-address. Thanks to
105 Gene Czarcinski for sorting this out.
107 Add a "wildcard" dhcp-range which works for any IPv6
108 subnet, --dhcp-range=::,static Useful for Stateless
109 DHCPv6. Thanks to Vladislav Grishenko for the patch.
111 Don't include lease-time in DHCPACK replies to DHCPINFORM
112 queries, since RFC-2131 says we shouldn't. Thanks to
113 Wouter Ibens for pointing this out.
115 Makefile tweak to do dependency checking on header files.
116 Thanks to Johan Peeters for the patch.
118 Check interface for outgoing unsolicited router
119 advertisements, rather than relying on interface address
120 configuration. Thanks to Gene Czarinski for the patch.
122 Handle better attempts to transmit on interfaces which are
123 still doing DAD, and specifically do not just transmit
124 without setting source address and interface, since this
125 can cause very puzzling effects when a router
126 advertisement goes astray. Thanks again to Gene Czarinski.
128 Get RA timers right when there is more than one
129 dhcp-range on a subnet.
133 Do duplicate dhcp-host address check in --test mode.
135 Check that tftp-root directories are accessible before
136 start-up. Thanks to Daniel Veillard for the initial patch.
138 Allow more than one --tfp-root flag. The per-interface
139 stuff is pointless without that.
141 Add --bind-dynamic. A hybrid mode between the default and
142 --bind-interfaces which copes with dynamically created
145 A couple of fixes to the build system for Android. Thanks
146 to Metin Kaya for the patches.
148 Remove the interface:<interface> argument in --dhcp-range, and
149 the interface argument to --enable-tftp. These were a
150 still-born attempt to allow automatic isolated
151 configuration by libvirt, but have never (to my knowledge)
152 been used, had very strange semantics, and have been
153 superceded by other mechanisms.
155 Fixed bug logging filenames when duplicate dhcp-host
156 addresses are found. Thanks to John Hanks for the patch.
158 Fix regression in 2.61 which broke caching of CNAME
159 chains. Thanks to Atul Gupta for the bug report.
161 Allow the target of a --cname flag to be another --cname.
163 Teach DHCPv6 about the RFC 4242 information-refresh-time
164 option, and add parsing if the minutes, hours and days
165 format for options. Thanks to Francois-Xavier Le Bail for
168 Allow "w" (for week) as multiplier in lease times, as well
169 as seconds, minutes, hours and days. Álvaro Gámez Machado
170 spotted the ommission.
172 Update French translation. Thanks to Gildas Le Nadan.
174 Allow a DBus service name to be given with --enable-dbus
175 which overrides the default,
176 uk.org.thekelleys.dnsmasq. Thanks to Mathieu
177 Trudel-Lapierre for the patch.
179 Set the "prefix on-link" bit in Router
180 Advertisements. Thanks to Gui Iribarren for the patch.
184 Update German translation. Thanks to Conrad Kostecki.
186 Cope with router-solict packets wich don't have a valid
187 source address. Thanks to Vladislav Grishenko for the patch.
189 Fixed bug which caused missing periodic router
190 advertisements with some configurations. Thanks to
191 Vladislav Grishenko for the patch.
193 Fixed bug which broke DHCPv6/RA with prefix lengths
194 which are not divisible by 8. Thanks to Andre Coetzee
197 Fix non-response to router-solicitations when
198 router-advertisement configured, but DHCPv6 not
199 configured. Thanks to Marien Zwart for the patch.
201 Add --dns-rr, to allow arbitrary DNS resource records.
203 Fixed bug which broke RA scheduling when an interface had
204 two addresses in the same network. Thanks to Jim Bos for
205 his help nailing this.
208 Re-write interface discovery code on *BSD to use
209 getifaddrs. This is more portable, more straightforward,
210 and allows us to find the prefix length for IPv6
213 Add ra-names, ra-stateless and slaac keywords for DHCPv6.
214 Dnsmasq can now synthesise AAAA records for dual-stack
215 hosts which get IPv6 addresses via SLAAC. It is also now
216 possible to use SLAAC and stateless DHCPv6, and to
217 tell clients to use SLAAC addresses as well as DHCP ones.
218 Thanks to Dave Taht for help with this.
220 Add --dhcp-duid to allow DUID-EN uids to be used.
222 Explicity send DHCPv6 replies to the correct port, instead
223 of relying on clients to send requests with the correct
224 source address, since at least one client in the wild gets
225 this wrong. Thanks to Conrad Kostecki for help tracking
228 Send a preference value of 255 in DHCPv6 replies when
229 --dhcp-authoritative is in effect. This tells clients not
230 to wait around for other DHCP servers.
232 Better logging of DHCPv6 options.
234 Add --host-record. Thanks to Rob Zwissler for the
237 Invoke the DHCP script with action "tftp" when a TFTP file
238 transfer completes. The size of the file, address to which
239 it was sent and complete pathname are supplied. Note that
240 version 2.60 introduced some script incompatibilties
241 associated with DHCPv6, and this is a further change. To
242 be safe, scripts should ignore unknown actions, and if
243 not IPv6-aware, should exit if the environment
244 variable DNSMASQ_IAID is set. The use-case for this is
245 to track netboot/install. Suggestion from Shantanu
248 Update contrib/port-forward/dnsmasq-portforward to reflect
251 Set the environment variable DNSMASQ_LOG_DHCP when running
252 the script id --log-dhcp is in effect, so that script can
253 taylor their logging verbosity. Suggestion from Malte
256 Arrange that addresses specified with --listen-address
257 work even if there is no interface carrying the
258 address. This is chiefly useful for IPv4 loopback
259 addresses, where any address in 127.0.0.0/8 is a valid
260 loopback address, but normally only 127.0.0.1 appears on
261 the lo interface. Thanks to Mathieu Trudel-Lapierre for
262 the idea and initial patch.
264 Fix crash, introduced in 2.60, when a DHCPINFORM is
265 received from a network which has no valid dhcp-range.
266 Thanks to Stephane Glondu for the bug report.
268 Add a new DHCP lease time keyword, "deprecated" for
269 --dhcp-range. This is only valid for IPv6, and sets the
270 preffered lease time for both DHCP and RA to zero. The
271 effect is that clients can continue to use the address
272 for existing connections, but new connections will use
273 other addresses, if they exist. This makes hitless
274 renumbering at least possible.
276 Fix bug in address6_available() which caused DHCPv6 lease
277 aquisition to fail if more than one dhcp-range in use.
279 Provide RDNSS and DNSSL data in router advertisements,
280 using the settings provided for DHCP options
281 option6:domain-search and option6:dns-server.
283 Tweak logo/favicon.ico to add some transparency. Thanks to
284 SamLT for work on this.
286 Don't cache data from non-recursive nameservers, since it
287 may erroneously look like a valid CNAME to a non-exitant
288 name. Thanks to Ben Winslow for finding this.
290 Call SO_BINDTODEVICE on the DHCP socket(s) when doing DHCP
291 on exactly one interface and --bind-interfaces is set. This
292 makes the OpenStack use-case of one dnsmasq per virtual
293 interface work. This is only available on Linux; it's not
294 supported on other platforms. Thanks to Vishvananda Ishaya
295 and the OpenStack team for the suggestion.
297 Updated French translation. Thanks to Gildas Le Nadan.
299 Give correct from-cache answers to explict CNAME queries.
300 Thanks to Rob Zwissler for spotting this.
302 Add --tftp-lowercase option. Thanks to Oliver Rath for the
305 Ensure that the DBus DhcpLeaseUpdated events are generated
306 when a lease goes through INIT_REBOOT state, even if the
307 dhcp-script is not in use. Thanks to Antoaneta-Ecaterina
310 Fix failure of TFTP over IPv4 on OpenBSD platform. Thanks
311 to Brad Smith for spotting this.
315 Fix compilation problem in Mac OS X Lion. Thanks to Olaf
316 Flebbe for the patch.
318 Fix DHCP when using --listen-address with an IP address
319 which is not the primary address of an interface.
321 Add --dhcp-client-update option.
323 Add Lua integration. Dnsmasq can now execute a DHCP
324 lease-change script written in Lua. This needs to be
325 enabled at compile time by setting HAVE_LUASCRIPT in
326 src/config.h or running "make COPTS=-DHAVE_LUASCRIPT"
327 Thanks to Jan-Piet Mens for the idea and proof-of-concept
330 Tidied src/config.h to distinguish between
331 platform-dependent compile-time options which are selected
332 automatically, and builder-selectable compile time
333 options. Document the latter better, and describe how to
334 set them from the make command line.
336 Tidied up IPPROTO_IP/SOL_IP (and IPv6 equivalent)
337 confusion. IPPROTO_IP works everywhere now.
339 Set TOS on DHCP sockets, this improves things on busy
340 wireless networks. Thanks to Dave Taht for the patch.
342 Determine VERSION automatically based on git magic:
343 release tags or hash values.
345 Improve start-up speed when reading large hosts files
346 containing many distinct addresses.
348 Fix problem if dnsmasq is started without the stdin,
349 stdout and stderr file descriptors open. This can manifest
350 itself as 100% CPU use. Thanks to Chris Moore for finding
353 Fix shell-scripting bug in bld/pkg-wrapper. Thanks to
354 Mark Mitchell for the patch.
356 Allow the TFP server or boot server in --pxe-service, to
357 be a domain name instead of an IP address. This allows for
358 round-robin to multiple servers, in the same way as
359 --dhcp-boot. A good suggestion from Cristiano Cumer.
361 Support BUILDDIR variable in the Makefile. Allows builds
362 for multiple archs from the same source tree with eg.
363 make BUILDDIR=linux (relative to dnsmasq tree)
364 make BUILDDIR=/tmp/openbsd (absolute path)
365 If BUILDDIR is not set, compilation happens in the src
366 directory, as before. Suggestion from Mark Mitchell.
368 Support DHCPv6. Support is there for the sort of things
369 the existing v4 server does, including tags, options,
370 static addresses and relay support. Missing is prefix
371 delegation, which is probably not required in the dnsmasq
372 niche, and an easy way to accept prefix delegations from
373 an upstream DHCPv6 server, which is. Future plans include
374 support for DHCPv6 router option and MAC address option
375 (to make selecting clients by MAC address work like IPv4).
376 These will be added as the standards mature.
377 This code has been tested, but this is the first release,
378 so don't bet the farm on it just yet. Many thanks to all
379 testers who have got it this far.
381 Support IPv6 router advertisements. This is a
382 simple-minded implementation, aimed at providing the
383 vestigial RA needed to go alongside IPv6. Is picks up
384 configuration from the DHCPv6 conf, and should just need
385 enabling with --enable-ra.
387 Fix long-standing wrinkle with --localise-queries that
388 could result in wrong answers when DNS packets arrive
389 via an interface other than the expected one. Thanks to
390 Lorenzo Milesi and John Hanks for spotting this one.
392 Update French translation. Thanks to Gildas Le Nadan.
394 Update Polish translation. Thanks to Jan Psota.
398 Fix regression in 2.58 which caused failure to start up
399 with some combinations of dnsmasq config and IPv6 kernel
400 network config. Thanks to Brielle Bruns for the bug
403 Improve dnsmasq's behaviour when network interfaces are
404 still doing duplicate address detection (DAD). Previously,
405 dnsmasq would wait up to 20 seconds at start-up for the
406 DAD state to terminate. This is broken for bridge
407 interfaces on recent Linux kernels, which don't start DAD
408 until the bridge comes up, and so can take arbitrary
409 time. The new behaviour lets dnsmasq poll for an arbitrary
410 time whilst providing service on other interfaces. Thanks
411 to Stephen Hemminger for pointing out the problem.
415 Provide a definition of the SA_SIZE macro where it's
416 missing. Fixes build failure on openBSD.
418 Don't include a zero terminator at the end of messages
419 sent to /dev/log when /dev/log is a datagram socket.
420 Thanks to Didier Rabound for spotting the problem.
422 Add --dhcp-sequential-ip flag, to force allocation of IP
423 addresses in ascending order. Note that the default
424 pseudo-random mode is in general better but some
425 server-deployment applications need this.
427 Fix problem where a server-id of 0.0.0.0 is sent to a
428 client when a dhcp-relay is in use if a client renews a
429 lease after dnsmasq restart and before any clients on the
430 subnet get a new lease. Thanks to Mike Ruiz for assistance
431 in chasing this one down.
433 Don't return NXDOMAIN to an AAAA query if we have CNAME
434 which points to an A record only: NODATA is the correct
435 reply in this case. Thanks to Tom Fernandes for spotting
438 Relax the need to supply a netmask in --dhcp-range for
439 networks which use a DHCP relay. Whilst this is still
440 desireable, in the absence of a netmask dnsmasq will use
441 a default based on the class (A, B, or C) of the address.
442 This should at least remove a cause of mysterious failure
443 for people using RFC1918 addresses and relays.
445 Add support for Linux conntrack connection marking. If
446 enabled with --conntrack, the connection mark for incoming
447 DNS queries will be copied to the outgoing connections
448 used to answer those queries. This allows clever firewall
449 and accounting stuff. Only available if dnsmasq is
450 compiled with HAVE_CONNTRACK and adds a dependency on
451 libnetfilter-conntrack. Thanks to Ed Wildgoose for the
452 initial idea, testing and sponsorship of this function.
454 Provide a sane error message when someone attempts to
455 match a tag in --dhcp-host.
457 Tweak the behaviour of --domain-needed, to avoid problems
458 with recursive nameservers downstream of dnsmasq. The new
459 behaviour only stops A and AAAA queries, and returns
460 NODATA rather than NXDOMAIN replies.
462 Efficiency fix for very large DHCP configurations, thanks
463 to James Gartrell and Mike Ruiz for help with this.
465 Allow the TFTP-server address in --dhcp-boot to be a
466 domain-name which is looked up in /etc/hosts. This can
467 give multiple IP addresses which are used round-robin,
468 thus doing TFTP server load-balancing. Thanks to Sushil
469 Agrawal for the patch.
471 When two tagged dhcp-options for a particular option
472 number are both valid, use the one which is valid without
473 a tag from the dhcp-range. Allows overriding of the value
474 of a DHCP option for a particular host as well as
475 per-network values. So
476 --dhcp-range=set:interface1,......
477 --dhcp-host=set:myhost,.....
478 --dhcp-option=tag:interface1,option:nis-domain,"domain1"
479 --dhcp-option=tag:myhost,option:nis-domain,"domain2"
480 will set the NIS-domain to domain1 for hosts in the range, but
481 override that to domain2 for a particular host.
483 Fix bug which resulted in truncated files and timeouts for
484 some TFTP transfers. The bug only occurs with netascii
485 transfers and needs an unfortunate relationship between
486 file size, blocksize and the number of newlines in the
487 last block before it manifests itself. Many thanks to
488 Alkis Georgopoulos for spotting the problem and providing
489 a comprehensive test-case.
491 Fix regression in TFTP server on *BSD platforms introduced
492 in version 2.56, due to confusion with sockaddr
493 length. Many thanks to Loic Pefferkorn for finding this.
495 Support scope-ids in IPv6 addresses of nameservers from
496 /etc/resolv.conf and in --server options. Eg
497 nameserver fe80::202:a412:4512:7bbf%eth0 or
498 server=fe80::202:a412:4512:7bbf%eth0. Thanks to
499 Michael Stapelberg for the suggestion.
501 Update Polish translation, thanks to Jan Psota.
503 Update French translation. Thanks to Gildas Le Nadan.
507 Add patches to allow build under Android.
509 Provide our own header for the DNS protocol, rather than
510 relying on arpa/nameser.h. This has proved more or less
511 defective over the years and the final straw is that it's
512 effectively empty on Android.
514 Fix regression in 2.56 which caused hex constants in
515 configuration to be rejected if they contain the '*'
518 Correct wrong casts of arguments to ctype.h functions,
519 isdigit(), isxdigit() etc. Thanks to Matthias Andree for
522 Allow build with IDN support independently from i18n.
523 IDN support continues to be included automatically
524 when i18n is included.
525 'make COPTS=-DHAVE_IDN' is the magic incantation.
527 Modify check on extraneous command line junk (added in
528 2.56) so that it doesn't complain about extra _empty_
529 arguments. Otherwise this breaks libvirt.
533 Add a patch to allow dnsmasq to get interface names right in a
534 Solaris zone. Thanks to Dj Padzensky for this.
536 Improve data-type parsing heuristics so that
537 --dhcp-option=option:domain-search,.
538 treats the value as a string and not an IP address.
539 Thanks to Clemens Fischer for spotting that.
541 Add IPv6 support to the TFTP server. Many thanks to Jan
542 'RedBully' Seiffert for the patches.
544 Log DNS queries at level LOG_INFO, rather then
545 LOG_DEBUG. This makes things consistent with DHCP
546 logging. Thanks to Adam Pribyl for spotting the problem.
548 Ensure that dnsmasq terminates cleanly when using
549 --syslog-async even if it cannot make a connection to the
552 Add --add-mac option. This is to support currently
553 experimental DNS filtering facilities. Thanks to Benjamin
554 Petrin for the orignal patch.
556 Fix bug which meant that tags were ignored in dhcp-range
557 configuration specifying PXE-proxy service. Thanks to
558 Cristiano Cumer for spotting this.
560 Raise an error if there is extra junk, not part of an
561 option, on the command line.
563 Flag a couple of log messages in cache.c as coming from
564 the DHCP subsystem. Thanks to Olaf Westrik for the patch.
566 Omit timestamps from logs when a) logging to stderr and
567 b) --keep-in-forground is set. The logging facility on the
568 other end of stderr can be assumned to supply them. Thanks
569 to John Hallam for the patch.
571 Don't complain about strings longer than 255 characters in
572 --txt-record, just split the long strings into 255
573 character chunks instead.
575 Fix crash on double-free. This bug can only happen when
576 dhcp-script is in use and then only in rare circumstances
577 triggered by high DHCP transaction rate and a slow
578 script. Thanks to Ferenc Wagner for finding the problem.
580 Only log that a file has been sent by TFTP after the
581 transfer has completed succesfully.
583 A good suggestion from Ferenc Wagner: extend
584 the --domain option to allow this sort of thing:
585 --domain=thekelleys.org.uk,192.168.0.0/24,local
586 which automatically creates
587 --local=/thekelleys.org.uk/
588 --local=/0.168.192.in-addr.arpa/
590 Tighten up syntax checking of hex contants in the config
591 file. Thanks to Fred Damen for spotting this.
593 Add dnsmasq logo/icon, contributed by Justin Swift. Many
596 Never cache DNS replies which have the 'cd' bit set, or
597 which result from queries forwarded with the 'cd' bit
598 set. The 'cd' bit instructs a DNSSEC validating server
599 upstream to ignore signature failures and return replies
600 anyway. Without this change it's possible to pollute the
601 dnsmasq cache with bad data by making a query with the
602 'cd' bit set and subsequent queries would return this data
603 without its being marked as suspect. Thanks to Anders
604 Kaseorg for pointing out this problem.
606 Add --proxy-dnssec flag, for compliance with RFC
607 4035. Dnsmasq will now clear the 'ad' bit in answers returned
608 from upstream validating nameservers unless this option is
611 Allow a filename of "-" for --conf-file to read
612 stdin. Suggestion from Timothy Redaelli.
614 Rotate the order of SRV records in replies, to provide
615 round-robin load balancing when all the priorities are
616 equal. Thanks to Peter McKinney for the suggestion.
619 contrib/MacOSX-launchd/uk.org.thekelleys.dnsmasq.plist
620 so that it doesn't log all queries to a file by
621 default. Thanks again to Peter McKinney.
623 By default, setting an IPv4 address for a domain but not
624 an IPv6 address causes dnsmasq to return
625 an NODATA reply for IPv6 (or vice-versa). So
626 --address=/google.com/1.2.3.4 stops IPv6 queries for
627 *google.com from being forwarded. Make it possible to
628 override this behaviour by defining the sematics if the
629 same domain appears in both --server and --address.
630 In that case, the --address has priority for the address
631 family in which is appears, but the --server has priority
632 of the address family which doesn't appear in --adddress
634 --address=/google.com/1.2.3.4
635 --server=/google.com/#
636 will return 1.2.3.4 for IPv4 queries for *.google.com but
637 forward IPv6 queries to the normal upstream nameserver.
638 Similarly when setting an IPv6 address
639 only this will allow forwarding of IPv4 queries. Thanks to
640 William for pointing out the need for this.
642 Allow more than one --dhcp-optsfile and --dhcp-hostsfile
643 and make them understand directories as arguments in the
644 same way as --addn-hosts. Suggestion from John Hanks.
646 Ignore rebinding requests for leases we don't know
647 about. Rebind is broadcast, so we might get to overhear a
648 request meant for another DHCP server. NAKing this is
649 wrong. Thanks to Brad D'Hondt for assistance with this.
651 Fix cosmetic bug which produced strange output when
652 dumping cache statistics with some configurations. Thanks
653 to Fedor Kozhevnikov for spotting this.
657 Fix crash when /etc/ethers is in use. Thanks to
658 Gianluigi Tiesi for finding this.
660 Fix crash in netlink_multicast(). Thanks to Arno Wald for
663 Allow the empty domain "." in dhcp domain-search (119)
668 There is no version 2.54 to avoid confusion with 2.53,
669 which incorrectly identifies itself as 2.54.
673 Fix failure to compile on Debian/kFreeBSD. Thanks to
674 Axel Beckert and Petr Salinger.
676 Fix code to avoid scary strict-aliasing warnings
677 generated by gcc 4.4.
679 Added FAQ entry warning about DHCP failures with Vista
680 when firewalls block 255.255.255.255.
682 Fixed bug which caused bad things to happen if a
683 resolv.conf file which exists is subsequently removed.
684 Thanks to Nikolai Saoukh for the patch.
686 Rationalised the DHCP tag system. Every configuration item
687 which can set a tag does so by adding "set:<tag>" and
688 every configuration item which is conditional on a tag is
689 made so by "tag:<tag>". The NOT operator changes to '!',
690 which is a bit more intuitive too. Dhcp-host directives
691 can set more than one tag now. The old '#' NOT,
692 "net:" prefix and no-prefixes are still honoured, so
693 no existing config file needs to be changed, but
694 the documentation and new-style config files should be
697 Added --tag-if to allow boolean operations on tags.
698 This allows complicated logic to be clearer and more
699 general. A great suggestion from Richard Voigt.
701 Add broadcast/unicast information to DHCP logging.
703 Allow --dhcp-broadcast to be unconditional.
705 Fixed incorrect behaviour with NOT <tag> conditionals in
706 dhcp-options. Thanks to Max Turkewitz for assistance
709 If we send vendor-class encapsulated options based on the
710 vendor-class supplied by the client, and no explicit
711 vendor-class option is given, echo back the vendor-class
714 Fix bug which stopped dnsmasq from matching both a
715 circuitid and a remoteid. Thanks to Ignacio Bravo for
718 Add --dhcp-proxy, which makes it possible to configure
719 dnsmasq to use a DHCP relay agent as a full proxy, with
720 all DHCP messages passing through the proxy. This is
721 useful if the relay adds extra information to the packets
722 it forwards, but cannot be configured with the RFC 5107
723 server-override option.
725 Added interface:<iface name> part to dhcp-range. The
726 semantics of this are very odd at first sight, but it
727 allows a single line of the form
728 dhcp-range=interface:virt0,192.168.0.4,192.168.0.200
729 to be added to dnsmasq configuration which then supplies
730 DHCP and DNS services to that interface, without affecting
731 what services are supplied to other interfaces and
732 irrespective of the existance or lack of
733 interface=<interface>
734 lines elsewhere in the dnsmasq configuration. The idea is
735 that such a line can be added automatically by libvirt
736 or equivalent systems, without disturbing any manual
739 Similarly to the above, allow --enable-tftp=<interface>
741 Allow a TFTP root to be set separately for requests via
742 different interfaces, --tftp-root=<path>,<interface>
744 Correctly handle and log clashes between CNAMES and
745 DNS names being given to DHCP leases. This fixes a bug
746 which caused nonsense IP addresses to be logged. Thanks to
747 Sergei Zhirikov for finding and analysing the problem.
749 Tweak flush_log so as to avoid leaving the log
750 file in non-blocking mode. O_NONBLOCK is a property of the
751 file, not the process/descriptor.
753 Fix contrib/Solaris10/create_package
754 (/usr/man -> /usr/share/man) Thanks to Vita Batrla.
756 Fix a problem where, if a client got a lease, then went
757 to another subnet and got another lease, then moved back,
758 it couldn't resume the old lease, but would instead get
759 a new address. Thanks to Leonardo Rodrigues for spotting
760 this and testing the fix.
762 Fix weird bug which sometimes omitted certain characters
763 from the start of quoted strings in dhcp-options. Thanks
764 to Dayton Turner for spotting the problem.
766 Add facility to redirect some domains to the standard
767 upstream servers: this allows something like
768 --server=/google.com/1.2.3.4 --server=/www.google.com/#
769 which will send queries for *.google.com to 1.2.3.4,
770 except *www.google.com which will be forwarded as usual.
771 Thanks to AJ Weber for prompting this addition.
773 Improve the hash-algorithm used to generate IP addresses
774 from MAC addresses during initial DHCP address
775 allocation. This improves performance when large numbers
776 of hosts with similar MAC addresses all try and get an IP
777 address at the same time. Thanks to Paul Smith for his
780 Tweak DHCP code so that --bridge-interface can be used to
781 select which IP alias of an interface should be used for
782 DHCP purposes on Linux. If eth0 has an alias eth0:dhcp
783 then adding --bridge-interface=eth0:dhcp,eth0 will use
784 the address of eth0:dhcp to determine the correct subnet
785 for DHCP address allocation. Thanks to Pawel Golaszewski
786 for prompting this and Eric Cooper for further testing.
788 Add --dhcp-generate-names. Suggestion by Ferenc Wagner.
790 Tweak DNS server selection algorithm when there is more
791 than one server available for a domain, eg.
792 --server=/mydomain/1.1.1.1
793 --server=/mydomain/2.2.2.2
794 Thanks to Alberto Cuesta-Canada for spotting a weakness
797 Add --max-ttl. Thanks to Fredrik Ringertz for the patch.
799 Allow --log-facility=- to force all logging to
800 stderr. Suggestion from Clemens Fischer.
802 Fix regression which caused configuration like
803 --address=/.domain.com/1.2.3.4 to be rejected. The dot to the
804 left of the domain has been implied and not required for a
805 long time, but it should be accepted for backward
806 compatibility. Thanks to Andrew Burcin for spotting this.
808 Add --rebind-domain-ok and --rebind-localhost-ok.
809 Suggestion from Clemens Fischer.
811 Log replies to queries of type TXT, when --log-queries
814 Fix compiler warnings when compiled with -DNO_DHCP. Thanks
815 to Shantanu Gadgil for the patch.
817 Updated French translation. Thanks to Gildas Le Nadan.
819 Updated Polish translation. Thanks to Jan Psota.
821 Updated German translation. Thanks to Matthias Andree.
823 Added contrib/static-arp, thanks to Darren Hoo.
825 Fix corruption of the domain when a name from /etc/hosts
826 overrides one supplied by a DHCP client. Thanks to Fedor
827 Kozhevnikov for spotting the problem.
829 Updated Spanish translation. Thanks to Chris Chatham.
833 Work around a Linux kernel bug which insists that the
834 length of the option passed to setsockopt must be at least
835 sizeof(int) bytes, even if we're calling SO_BINDTODEVICE
836 and the device name is "lo". Note that this is fixed
837 in kernel 2.6.31, but the workaround is harmless and
838 allows earlier kernels to be used. Also fix dnsmasq
839 bug which reported the wrong address when this failed.
840 Thanks to Fedor for finding this.
842 The API for IPv6 PKTINFO changed around Linux kernel
843 2.6.14. Workaround the case where dnsmasq is compiled
844 against newer headers, but then run on an old kernel:
845 necessary for some *WRT distros.
847 Re-read the set of network interfaces when re-loading
848 /etc/resolv.conf if --bind-interfaces is not set. This
849 handles the case that loopback interfaces do not exist
850 when dnsmasq is first started.
852 Tweak the PXE code to support port 4011. This should
853 reduce broadcasts and make things more reliable when other
854 servers are around. It also improves inter-operability
855 with certain clients.
857 Make a pxe-service configuration with no filename or boot
858 service type legal: this does a local boot. eg.
859 pxe-service=x86PC, "Local boot"
861 Be more conservative in detecting "A for A"
862 queries. Dnsmasq checks if the name in a type=A query looks
863 like a dotted-quad IP address and answers the query itself
864 if so, rather than forwarding it. Previously dnsmasq
865 relied in the library function inet_addr() to convert
866 addresses, and that will accept some things which are
867 confusing in this context, like 1.2.3 or even just
868 1234. Now we only do A for A processing for four decimal
869 numbers delimited by dots.
871 A couple of tweaks to fix compilation on Solaris. Thanks
872 to Joel Macklow for help with this.
874 Another Solaris compilation tweak, needed for Solaris
875 2009.06. Thanks to Lee Essen for that.
877 Added extract packaging stuff from Lee Essen to
880 Increased the default limit on number of leases to 1000
881 (from 150). This is mainly a defence against DoS attacks,
882 and for the average "one for two class C networks"
883 installation, IP address exhaustion does that just as
884 well. Making the limit greater than the number of IP
885 addresses available in such an installation removes a
886 surprise which otherwise can catch people out.
888 Removed extraneous trailing space in the value of the
889 DNSMASQ_TIME_REMAINING DNSMASQ_LEASE_LENGTH and
890 DNSMASQ_LEASE_EXPIRES environment variables. Thanks to
891 Gildas Le Nadan for spotting this.
893 Provide the network-id tags for a DHCP transaction to
894 the lease-change script in the environment variable
895 DNSMASQ_TAGS. A good suggestion from Gildas Le Nadan.
897 Add support for RFC3925 "Vendor-Identifying Vendor
898 Options". The syntax looks like this:
899 --dhcp-option=vi-encap:<enterprise number>, .........
901 Add support to --dhcp-match to allow matching against
902 RFC3925 "Vendor-Identifying Vendor Classes". The syntax
904 --dhcp-match=tag,vi-encap<enterprise number>, <value>
906 Add some application specific code to assist in
907 implementing the Broadband forum TR069 CPE-WAN
908 specification. The details are in contrib/CPE-WAN/README
910 Increase the default DNS packet size limit to 4096, as
911 recommended by RFC5625 section 4.4.3. This can be
912 reconfigured using --edns-packet-max if needed. Thanks to
913 Francis Dupont for pointing this out.
915 Rewrite query-ids even for TSIG signed packets, since
916 this is allowed by RFC5625 section 4.5.
918 Use getopt_long by default on OS X. It has been supported
919 since version 10.3.0. Thanks to Arek Dreyer for spotting
922 Added up-to-date startup configuration for MacOSX/launchd
923 in contrib/MacOSX-launchd. Thanks to Arek Dreyer for
926 Fix link error when including Dbus but excluding DHCP.
927 Thanks to Oschtan for the bug report.
929 Updated French translation. Thanks to Gildas Le Nadan.
931 Updated Polish translation. Thanks to Jan Psota.
933 Updated Spanish translation. Thanks to Chris Chatham.
935 Fixed confusion about domains, when looking up DHCP hosts
936 in /etc/hosts. This could cause spurious "Ignoring
937 domain..." messages. Thanks to Fedor Kozhevnikov for
938 finding and analysing the problem.
942 Add support for internationalised DNS. Non-ASCII characters
943 in domain names found in /etc/hosts, /etc/ethers and
944 /etc/dnsmasq.conf will be correctly handled by translation to
945 punycode, as specified in RFC3490. This function is only
946 available if dnsmasq is compiled with internationalisation
947 support, and adds a dependency on GNU libidn. Without i18n
948 support, dnsmasq continues to be compilable with just
949 standard tools. Thanks to Yves Dorfsman for the
952 Add two more environment variables for lease-change scripts:
953 First, DNSMASQ_SUPPLIED_HOSTNAME; this is set to the hostname
954 supplied by a client, even if the actual hostname used is
955 over-ridden by dhcp-host or dhcp-ignore-names directives.
956 Also DNSMASQ_RELAY_ADDRESS which gives the address of
957 a DHCP relay, if used.
958 Suggestions from Michael Rack.
960 Fix regression which broke echo of relay-agent
961 options. Thanks to Michael Rack for spotting this.
963 Don't treat option 67 as being interchangeable with
964 dhcp-boot parameters if it's specified as
967 Make the code to call scripts on lease-change compile-time
968 optional. It can be switched off by editing src/config.h
969 or building with "make COPTS=-DNO_SCRIPT".
971 Make the TFTP server cope with filenames from Windows/DOS
972 which use '\' as pathname separator. Thanks to Ralf for
975 Updated Polish translation. Thanks to Jan Psota.
977 Warn if an IP address is duplicated in /etc/ethers. Thanks
978 to Felix Schwarz for pointing this out.
980 Teach --conf-dir to take an option list of file suffices
981 which will be ignored when scanning the directory. Useful
982 for backup files etc. Thanks to Helmut Hullen for the
985 Add new DHCP option named tftpserver-address, which
986 corresponds to the third argument of dhcp-boot. This
987 allows the complete functionality of dhcp-boot to be
988 replicated with dhcp-option. Useful when using
991 Test which upstream nameserver to use every 10 seconds
992 or 50 queries and not just when a query times out and
993 is retried. This should improve performance when there
994 is a slow nameserver in the list. Thanks to Joe for the
997 Don't do any PXE processing, even for clients with the
998 correct vendorclass, unless at least one pxe-prompt or
999 pxe-service option is given. This stops dnsmasq
1000 interfering with proxy PXE subsystems when it is just
1001 the DHCP server. Thanks to Spencer Clark for spotting this.
1003 Limit the blocksize used for TFTP transfers to a value
1004 which avoids packet fragmentation, based on the MTU of the
1005 local interface. Many netboot ROMs can't cope with
1008 Honour dhcp-ignore configuration for PXE and proxy-PXE
1009 requests. Thanks to Niels Basjes for the bug report.
1011 Updated French translation. Thanks to Gildas Le Nadan.
1015 Fix security problem which allowed any host permitted to
1016 do TFTP to possibly compromise dnsmasq by remote buffer
1017 overflow when TFTP enabled. Thanks to Core Security
1018 Technologies and Iván Arce, Pablo Hernán Jorge, Alejandro
1019 Pablo Rodriguez, Martín Coco, Alberto Soliño Testa and
1020 Pablo Annetta. This problem has Bugtraq id: 36121
1023 Fix a problem which allowed a malicious TFTP client to
1024 crash dnsmasq. Thanks to Steve Grubb at Red Hat for
1025 spotting this. This problem has Bugtraq id: 36120 and
1030 Fix regression in 2.48 which disables the lease-change
1031 script. Thanks to Jose Luis Duran for spotting this.
1033 Log TFTP "file not found" errors. These were not logged,
1034 since a normal PXELinux boot generates many of them, but
1035 the lack of the messages seems to be more confusing than
1036 routinely seeing them when there is no real error.
1038 Update Spanish translation. Thanks to Chris Chatham.
1042 Archived the extensive, backwards, changelog to
1043 CHANGELOG.archive. The current changelog now runs from
1044 version 2.43 and runs conventionally.
1046 Fixed bug which broke binding of servers to physical
1047 interfaces when interface names were longer than four
1048 characters. Thanks to MURASE Katsunori for the patch.
1050 Fixed netlink code to check that messages come from the
1051 correct source, and not another userspace process. Thanks
1052 to Steve Grubb for the patch.
1054 Maintainability drive: removed bug and missing feature
1055 workarounds for some old platforms. Solaris 9, OpenBSD
1056 older than 4.1, Glibc older than 2.2, Linux 2.2.x and
1057 DBus older than 1.1.x are no longer supported.
1059 Don't read included configuration files more than once:
1060 allows complex configuration structures without problems.
1062 Mark log messages from the various subsystems in dnsmasq:
1063 messages from the DHCP subsystem now have the ident string
1064 "dnsmasq-dhcp" and messages from TFTP have ident
1065 "dnsmasq-tftp". Thanks to Olaf Westrik for the patch.
1067 Fix possible infinite DHCP protocol loop when an IP
1068 address nailed to a hostname (not a MAC address) and a
1069 host sometimes provides the name, sometimes not.
1071 Allow --addn-hosts to take a directory: all the files
1072 in the directory are read. Thanks to Phil Cornelius for
1075 Support --bridge-interface on all platforms, not just BSD.
1077 Added support for advanced PXE functions. It's now
1078 possible to define a prompt and menu options which will
1079 be displayed when a client PXE boots. It's also possible to
1080 hand-off booting to other boot servers. Proxy-DHCP, where
1081 dnsmasq just supplies the PXE information and another DHCP
1082 server does address allocation, is also allowed. See the
1083 --pxe-prompt and --pxe-service keywords. Thanks to
1084 Alkis Georgopoulos for the suggestion and Guilherme Moro
1085 and Michael Brown for assistance.
1087 Improvements to DHCP logging. Thanks to Tom Metro for
1090 Add ability to build dnsmasq without DHCP support. To do
1091 this, edit src/config.h or build with
1092 "make COPTS=-DNO_DHCP". Thanks to Mahavir Jain for the patch.
1094 Added --test command-line switch - syntax check
1095 configuration files only.
1097 Updated French translation. Thanks to Gildas Le Nadan.
1101 Updated French translation. Thanks to Gildas Le Nadan.
1103 Fixed interface enumeration code to work on NetBSD
1104 5.0. Thanks to Roy Marples for the patch.
1106 Updated config.h to use the same location for the lease
1107 file on NetBSD as the other *BSD variants. Also allow
1108 LEASEFILE and CONFFILE symbols to be overriden in CFLAGS.
1110 Handle duplicate address detection on IPv6 more
1111 intelligently. In IPv6, an interface can have an address
1112 which is not usable, because it is still undergoing DAD
1113 (such addresses are marked "tentative"). Attempting to
1114 bind to an address in this state returns an error,
1115 EADDRNOTAVAIL. Previously, on getting such an error,
1116 dnsmasq would silently abandon the address, and never
1117 listen on it. Now, it retries once per second for 20
1118 seconds before generating a fatal error. 20 seconds should
1119 be long enough for any DAD process to complete, but can be
1120 adjusted in src/config.h if necessary. Thanks to Martin
1121 Krafft for the bug report.
1123 Add DBus introspection. Patch from Jeremy Laine.
1125 Update Dbus configuration file. Patch from Colin Walters.
1127 http://bugs.freedesktop.org/show_bug.cgi?id=18961
1129 Support arbitrarily encapsulated DHCP options, suggestion
1130 and initial patch from Samium Gromoff. This is useful for
1131 (eg) gPXE, which expect all its private options to be
1132 encapsulated inside a single option 175. So, eg,
1134 dhcp-option = encap:175, 190, "iscsi-client0"
1135 dhcp-option = encap:175, 191, "iscsi-client0-secret"
1137 will provide iSCSI parameters to gPXE.
1139 Enhance --dhcp-match to allow testing of the contents of a
1140 client-sent option, as well as its presence. This
1141 application in mind for this is RFC 4578
1142 client-architecture specifiers, but it's generally useful.
1143 Joey Korkames suggested the enhancement.
1145 Move from using the IP_XMIT_IF ioctl to IP_BOUND_IF on
1146 OpenSolaris. Thanks to Bastian Machek for the heads-up.
1148 No longer complain about blank lines in
1149 /etc/ethers. Thanks to Jon Nelson for the patch.
1151 Fix binding of servers to physical devices, eg
1152 --server=/domain/1.2.3.4@eth0 which was broken from 2.43
1153 onwards unless --query-port=0 set. Thanks to Peter Naulls
1156 Reply to DHCPINFORM requests even when the supplied ciaddr
1157 doesn't fall in any dhcp-range. In this case it's not
1158 possible to supply a complete configuration, but
1159 individually-configured options (eg PAC) may be useful.
1161 Allow the source address of an alias to be a range:
1162 --alias=192.168.0.0,10.0.0.0,255.255.255.0 maps the whole
1163 subnet 192.168.0.0->192.168.0.255 to 10.0.0.0->10.0.0.255,
1165 --alias=192.168.0.10-192.168.0.40,10.0.0.0,255.255.255.0
1166 maps only the 192.168.0.10->192.168.0.40 region. Thanks to
1167 Ib Uhrskov for the suggestion.
1169 Don't dynamically allocate DHCP addresses which may break
1170 Windows. Addresses which end in .255 or .0 are broken in
1171 Windows even when using supernetting.
1172 --dhcp-range=192.168.0.1,192.168.1.254,255,255,254.0 means
1173 192.168.0.255 is a valid IP address, but not for Windows.
1174 See Microsoft KB281579. We therefore no longer allocate
1175 these addresses to avoid hard-to-diagnose problems.
1177 Update Polish translation. Thanks to Jan Psota.
1179 Delete the PID-file when dnsmasq shuts down. Note that by
1180 this time, dnsmasq is normally not running as root, so
1181 this will fail if the PID-file is stored in a root-owned
1182 directory; such failure is silently ignored. To take
1183 advantage of this feature, the PID-file must be stored in a
1184 directory owned and write-able by the user running
1189 Allow --bootp-dynamic to take a netid tag, so that it may
1190 be selectively enabled. Thanks to Olaf Westrik for the
1193 Remove ISC-leasefile reading code. This has been
1194 deprecated for a long time, and last time I removed it, it
1195 ended up going back by request of one user. This time,
1196 it's gone for good; otherwise it would need to be
1197 re-worked to support multiple domains (see below).
1199 Support DHCP clients in multiple DNS domains. This is a
1200 long-standing request. Clients are assigned to a domain
1201 based in their IP address.
1203 Add --dhcp-fqdn flag, which changes behaviour if DNS names
1204 assigned to DHCP clients. When this is set, there must be
1205 a domain associated with each client, and only
1206 fully-qualified domain names are added to the DNS. The
1207 advantage is that the only the FQDN needs to be unique,
1208 so that two or more DHCP clients can share a hostname, as
1209 long as they are in different domains.
1211 Set environment variable DNSMASQ_DOMAIN when invoking
1212 lease-change script. This may be useful information to
1213 have now that it's variable.
1215 Tighten up data-checking code for DNS packet
1216 handling. Thanks to Steve Dodd who found certain illegal
1217 packets which could crash dnsmasq. No memory overwrite was
1218 possible, so this is not a security issue beyond the DoS
1221 Update example config dhcp option 47, the previous
1222 suggestion generated an illegal, zero-length,
1223 option. Thanks to Matthias Andree for finding this.
1225 Rewrite hosts-file reading code to remove the limit of
1226 1024 characters per line. John C Meuser found this.
1228 Create a net-id tag with the name of the interface on
1229 which the DHCP request was received.
1231 Fixed minor memory leak in DBus code, thanks to Jeremy
1232 Laine for the patch.
1234 Emit DBus signals as the DHCP lease database
1235 changes. Thanks to Jeremy Laine for the patch.
1237 Allow for more that one MAC address in a dhcp-host
1238 line. This configuration tells dnsmasq that it's OK to
1239 abandon a DHCP lease of the fixed address to one MAC
1240 address, if another MAC address in the dhcp-host statement
1241 asks for an address. This is useful to give a fixed
1242 address to a host which has two network interfaces
1243 (say, a laptop with wired and wireless interfaces.)
1244 It's very important to ensure that only one interface
1245 at a time is up, since dnsmasq abandons the first lease
1246 and re-uses the address before the leased time has
1247 elapsed. John Gray suggested this.
1249 Tweak the response to a DHCP request packet with a wrong
1250 server-id when --dhcp-authoritative is set; dnsmasq now
1251 returns a DHCPNAK, rather than silently ignoring the
1252 packet. Thanks to Chris Marget for spotting this
1255 Add --cname option. This provides a limited alias
1256 function, usable for DHCP names. Thanks to AJ Weber for
1257 suggestions on this.
1259 Updated contrib/webmin with latest version from Neil
1262 Updated Polish translation. Thanks to Jan Psota.
1264 Correct the text names for DHCP options 64 and 65 to be
1265 "nis+-domain" and "nis+-servers".
1267 Updated Spanish translation. Thanks to Chris Chatham.
1269 Force re-reading of /etc/resolv.conf when an "interface
1274 Fix total DNS failure in release 2.44 unless --min-port
1275 specified. Thanks to Steven Barth and Grant Coady for
1276 bugreport. Also reject out-of-range port spec, which could
1277 break things too: suggestion from Gilles Espinasse.
1281 Fix crash when unknown client attempts to renew a DHCP
1282 lease, problem introduced in version 2.43. Thanks to
1283 Carlos Carvalho for help chasing this down.
1285 Fix potential crash when a host which doesn't have a lease
1286 does DHCPINFORM. Again introduced in 2.43. This bug has
1287 never been reported in the wild.
1289 Fix crash in netlink code introduced in 2.43. Thanks to
1290 Jean Wolter for finding this.
1292 Change implementation of min_port to work even if min-port
1295 Patch to enable compilation of latest Mac OS X. Thanks to
1298 Update Spanish translation. Thanks to Christopher Chatham.
1302 Updated Polish translation. Thanks to Jan Psota.
1304 Flag errors when configuration options are repeated
1307 Further tweaks for GNU/kFreeBSD
1309 Add --no-wrap to msgmerge call - provides nicer .po file
1312 Honour lease-time spec in dhcp-host lines even for
1313 BOOTP. The user is assumed to known what they are doing in
1314 this case. (Hosts without the time spec still get infinite
1315 leases for BOOTP, over-riding the default in the
1316 dhcp-range.) Thanks to Peter Katzmann for uncovering this.
1318 Fix problem matching relay-agent ids. Thanks to Michael
1319 Rack for the bug report.
1321 Add --naptr-record option. Suggestion from Johan
1324 Implement RFC 5107 server-id-override DHCP relay agent
1327 Apply patches from Stefan Kruger for compilation on
1328 Solaris 10 under Sun studio.
1330 Yet more tweaking of Linux capability code, to suppress
1331 pointless wingeing from kernel 2.6.25 and above.
1333 Improve error checking during startup. Previously, some
1334 errors which occurred during startup would be worked
1335 around, with dnsmasq still starting up. Some were logged,
1336 some silent. Now, they all cause a fatal error and dnsmasq
1337 terminates with a non-zero exit code. The errors are those
1338 associated with changing uid and gid, setting process
1339 capabilities and writing the pidfile. Thanks to Uwe
1340 Gansert and the Suse security team for pointing out
1341 this improvement, and Bill Reimers for good implementation
1344 Provide NO_LARGEFILE compile option to switch off largefile
1345 support when compiling against versions of uclibc which
1346 don't support it. Thanks to Stephane Billiart for the patch.
1348 Implement random source ports for interactions with
1349 upstream nameservers. New spoofing attacks have been found
1350 against nameservers which do not do this, though it is not
1351 clear if dnsmasq is vulnerable, since to doesn't implement
1352 recursion. By default dnsmasq will now use a different
1353 source port (and socket) for each query it sends
1354 upstream. This behaviour can suppressed using the
1355 --query-port option, and the old default behaviour
1356 restored using --query-port=0. Explicit source-port
1357 specifications in --server configs are still honoured.
1359 Replace the random number generator, for better
1360 security. On most BSD systems, dnsmasq uses the
1361 arc4random() RNG, which is secure, but on other platforms,
1362 it relied on the C-library RNG, which may be
1363 guessable and therefore allow spoofing. This release
1364 replaces the libc RNG with the SURF RNG, from Daniel
1365 J. Berstein's DJBDNS package.
1367 Don't attempt to change user or group or set capabilities
1368 if dnsmasq is run as a non-root user. Without this, the
1369 change from soft to hard errors when these fail causes
1370 problems for non-root daemons listening on high
1371 ports. Thanks to Patrick McLean for spotting this.
1373 Updated French translation. Thanks to Gildas Le Nadan.
1377 The changelog for version 2.42 and earlier is
1378 available in CHANGELOG.archive.
