1 version 2.67
2 Fix crash if upstream server returns SERVFAIL when
3 --conntrack in use. Thanks to Giacomo Tazzari for finding
4 this and supplying the patch.
6 Repair regression in 2.64. That release stopped sending
7 lease-time information in the reply to DHCPINFORM
8 requests, on the correct grounds that it was a standards
9 violation. However, this broke the dnsmasq-specific
10 dhcp_lease_time utility. Now, DHCPINFORM returns
11 lease-time only if it's specifically requested
12 (maintaining standards) and the dhcp_lease_time utility
13 has been taught to ask for it (restoring functionality).
15 Fix --dhcp-match, --dhcp-vendorclass and --dhcp-userclass
16 to work with BOOTP and well as DHCP. Thanks to Peter
17 Korsgaard for spotting the problem.
19 Add --synth-domain. Thanks to Vishvananda Ishaya for
20 suggesting this.
22 Fix failure to compile ipset.c if old kernel headers are
23 in use. Thanks to Eugene Rudoy for pointing this out.
25 Handle IPv4 interface-address labels in Linux. These are
26 often used to emulate the old IP-alias addresses. Before,
27 using --interface=eth0 would service all the addresses of
28 eth0, including ones configured as aliases, which appear
29 in ifconfig as eth0:0. Now, only addresses with the label
30 eth0 are active. This is not backwards compatible: if you
31 want to continue to bind the aliases too, you need to add
32 eg. --interface=eth0:0 to the config.
34 Fix "failed to set SO_BINDTODEVICE on DHCP socket: Socket
35 operation on non-socket" error on startup with
36 configurations which have exactly one --interface option
37 and do RA but _not_ DHCPv6. Thanks to Trever Adams for the
38 bug report.
40 Generalise --interface-name to cope with IPv6 addresses
41 and multiple addresses per interface per address family.
43 Fix option parsing for --dhcp-host, which was generating a
44 spurious error when all seven possible items were
45 included. Thanks to Zhiqiang Wang for the bug report.
47 Remove restriction on prefix-length in --auth-zone. Thanks
48 to Toke Hoiland-Jorgensen for suggesting this.
50 Log when the maximum number of concurrent DNS queries is
51 reached. Thanks to Marcelo Salhab Brogliato for the patch.
53 If wildcards are used in --interface, don't assume that
54 there will only ever be one available interface for DHCP
55 just because there is one at start-up. More may appear, so
56 we can't use SO_BINDTODEVICE. Thanks to Natrio for the bug
57 report.
60 version 2.66
61 Add the ability to act as an authoritative DNS
62 server. Dnsmasq can now answer queries from the wider 'net
63 with local data, as long as the correct NS records are set
64 up. Only local data is provided, to avoid creating an open
65 DNS relay. Zone transfer is supported, to allow secondary
66 servers to be configured.
68 Add "constructed DHCP ranges" for DHCPv6. This is intended
69 for IPv6 routers which get prefixes dynamically via prefix
70 delegation. With suitable configuration, stateful DHCPv6
71 and RA can happen automatically as prefixes are delegated
72 and then deprecated, without having to re-write the
73 dnsmasq configuration file or restart the daemon. Thanks to
74 Steven Barth for extensive testing and development work on
75 this idea.
77 Fix crash on startup on Solaris 11. Regression probably
78 introduced in 2.61. Thanks to Geoff Johnstone for the
79 patch.
81 Add code to make behaviour for TCP DNS requests that same
82 as for UDP requests, when a request arrives for an allowed
83 address, but via a banned interface. This change is only
84 active on Linux, since the relevant API is missing (AFAIK)
85 on other platforms. Many thanks to Tomas Hozza for
86 spotting the problem, and doing invaluable discovery of
87 the obscure and undocumented API required for the solution.
89 Don't send the default DHCP option advertising dnsmasq as
90 the local DNS server if dnsmasq is configured to not act
91 as DNS server, or it's configured to a non-standard port.
93 Add DNSMASQ_CIRCUIT_ID, DNSMASQ_SUBCRIBER_ID,
94 DNSMASQ_REMOTE_ID variables to the environment of the
95 lease-change script (and the corresponding Lua). These hold
96 information inserted into the DHCP request by a DHCP relay
97 agent. Thanks to Lakefield Communications for providing a
98 bounty for this addition.
100 Fixed crash, introduced in 2.64, whilst handling DHCPv6
101 information-requests with some common configurations.
102 Thanks to Robert M. Albrecht for the bug report and
103 chasing the problem.
105 Add --ipset option. Thanks to Jason A. Donenfeld for the
106 patch.
108 Don't erroneously reject some option names in --dhcp-match
109 options. Thanks to Benedikt Hochstrasser for the bug report.
111 Allow a trailing '*' wildcard in all interface-name
112 configurations. Thanks to Christian Parpart for the patch.
114 Handle the situation where libc headers define
115 SO_REUSEPORT, but the kernel in use doesn't, to cope with
116 the introduction of this option to Linux. Thanks to Rich
117 Felker for the bug report.
119 Update Polish translation. Thanks to Jan Psota.
121 Fix crash if the configured DHCP lease limit is
122 reached. Regression occurred in 2.61. Thanks to Tsachi for
123 the bug report.
125 Update the French translation. Thanks to Gildas le Nadan.
128 version 2.65
129 Fix regression which broke forwarding of queries sent via
130 TCP which are not for A and AAAA and which were directed to
131 non-default servers. Thanks to Niax for the bug report.
133 Fix failure to build with DHCP support excluded. Thanks to
134 Gustavo Zacarias for the patch.
136 Fix nasty regression in 2.64 which completely broke cacheing.
139 version 2.64
140 Handle DHCP FQDN options with all flag bits zero and
141 --dhcp-client-update set. Thanks to Bernd Krumbroeck for
142 spotting the problem.
144 Finesse the check for /etc/hosts names which conflict with
145 DHCP names. Previously a name/address pair in /etc/hosts
146 which didn't match the name/address of a DHCP lease would
147 generate a warning. Now that only happesn if there is not
148 also a match. This allows multiple addresses for a name in
149 /etc/hosts with one of them assigned via DHCP.
151 Fix broken vendor-option processing for BOOTP. Thanks to
152 Hans-Joachim Baader for the bug report.
154 Don't report spurious netlink errors, regression in
155 2.63. Thanks to Vladislav Grishenko for the patch.
157 Flag DHCP or DHCPv6 in starup logging. Thanks to
158 Vladislav Grishenko for the patch.
160 Add SetServersEx method in DBus interface. Thanks to Dan
161 Williams for the patch.
163 Add SetDomainServers method in DBus interface. Thanks to
164 Roy Marples for the patch.
166 Fix build with later Lua libraries. Thansk to Cristian
167 Rodriguez for the patch.
169 Add --max-cache-ttl option. Thanks to Dennis Kaarsemaker
170 for the patch.
172 Fix breakage of --host-record parsing, resulting in
173 infinte loop at startup. Regression in 2.63. Thanks to
174 Haim Gelfenbeyn for spotting this.
176 Set SO_REUSEADDRESS and SO_V6ONLY options on the DHCPv6
177 socket, this allows multiple instances of dnsmasq on a
178 single machine, in the same way as for DHCPv4. Thanks to
179 Gene Czarcinski and Vladislav Grishenko for work on this.
181 Fix DHCPv6 to do access control correctly when it's
182 configured with --listen-address. Thanks to
183 Gene Czarcinski for sorting this out.
185 Add a "wildcard" dhcp-range which works for any IPv6
186 subnet, --dhcp-range=::,static Useful for Stateless
187 DHCPv6. Thanks to Vladislav Grishenko for the patch.
189 Don't include lease-time in DHCPACK replies to DHCPINFORM
190 queries, since RFC-2131 says we shouldn't. Thanks to
191 Wouter Ibens for pointing this out.
193 Makefile tweak to do dependency checking on header files.
194 Thanks to Johan Peeters for the patch.
196 Check interface for outgoing unsolicited router
197 advertisements, rather than relying on interface address
198 configuration. Thanks to Gene Czarinski for the patch.
200 Handle better attempts to transmit on interfaces which are
201 still doing DAD, and specifically do not just transmit
202 without setting source address and interface, since this
203 can cause very puzzling effects when a router
204 advertisement goes astray. Thanks again to Gene Czarinski.
206 Get RA timers right when there is more than one
207 dhcp-range on a subnet.
210 version 2.63
211 Do duplicate dhcp-host address check in --test mode.
213 Check that tftp-root directories are accessible before
214 start-up. Thanks to Daniel Veillard for the initial patch.
216 Allow more than one --tfp-root flag. The per-interface
217 stuff is pointless without that.
219 Add --bind-dynamic. A hybrid mode between the default and
220 --bind-interfaces which copes with dynamically created
221 interfaces.
223 A couple of fixes to the build system for Android. Thanks
224 to Metin Kaya for the patches.
226 Remove the interface:<interface> argument in --dhcp-range, and
227 the interface argument to --enable-tftp. These were a
228 still-born attempt to allow automatic isolated
229 configuration by libvirt, but have never (to my knowledge)
230 been used, had very strange semantics, and have been
231 superceded by other mechanisms.
233 Fixed bug logging filenames when duplicate dhcp-host
234 addresses are found. Thanks to John Hanks for the patch.
236 Fix regression in 2.61 which broke caching of CNAME
237 chains. Thanks to Atul Gupta for the bug report.
239 Allow the target of a --cname flag to be another --cname.
241 Teach DHCPv6 about the RFC 4242 information-refresh-time
242 option, and add parsing if the minutes, hours and days
243 format for options. Thanks to Francois-Xavier Le Bail for
244 the suggestion.
246 Allow "w" (for week) as multiplier in lease times, as well
247 as seconds, minutes, hours and days. Álvaro Gámez Machado
248 spotted the ommission.
250 Update French translation. Thanks to Gildas Le Nadan.
252 Allow a DBus service name to be given with --enable-dbus
253 which overrides the default,
254 uk.org.thekelleys.dnsmasq. Thanks to Mathieu
255 Trudel-Lapierre for the patch.
257 Set the "prefix on-link" bit in Router
258 Advertisements. Thanks to Gui Iribarren for the patch.
261 version 2.62
262 Update German translation. Thanks to Conrad Kostecki.
264 Cope with router-solict packets wich don't have a valid
265 source address. Thanks to Vladislav Grishenko for the patch.
267 Fixed bug which caused missing periodic router
268 advertisements with some configurations. Thanks to
269 Vladislav Grishenko for the patch.
271 Fixed bug which broke DHCPv6/RA with prefix lengths
272 which are not divisible by 8. Thanks to Andre Coetzee
273 for spotting this.
275 Fix non-response to router-solicitations when
276 router-advertisement configured, but DHCPv6 not
277 configured. Thanks to Marien Zwart for the patch.
279 Add --dns-rr, to allow arbitrary DNS resource records.
281 Fixed bug which broke RA scheduling when an interface had
282 two addresses in the same network. Thanks to Jim Bos for
283 his help nailing this.
285 version 2.61
286 Re-write interface discovery code on *BSD to use
287 getifaddrs. This is more portable, more straightforward,
288 and allows us to find the prefix length for IPv6
289 addresses.
291 Add ra-names, ra-stateless and slaac keywords for DHCPv6.
292 Dnsmasq can now synthesise AAAA records for dual-stack
293 hosts which get IPv6 addresses via SLAAC. It is also now
294 possible to use SLAAC and stateless DHCPv6, and to
295 tell clients to use SLAAC addresses as well as DHCP ones.
296 Thanks to Dave Taht for help with this.
298 Add --dhcp-duid to allow DUID-EN uids to be used.
300 Explicity send DHCPv6 replies to the correct port, instead
301 of relying on clients to send requests with the correct
302 source address, since at least one client in the wild gets
303 this wrong. Thanks to Conrad Kostecki for help tracking
304 this down.
306 Send a preference value of 255 in DHCPv6 replies when
307 --dhcp-authoritative is in effect. This tells clients not
308 to wait around for other DHCP servers.
310 Better logging of DHCPv6 options.
312 Add --host-record. Thanks to Rob Zwissler for the
313 suggestion.
315 Invoke the DHCP script with action "tftp" when a TFTP file
316 transfer completes. The size of the file, address to which
317 it was sent and complete pathname are supplied. Note that
318 version 2.60 introduced some script incompatibilties
319 associated with DHCPv6, and this is a further change. To
320 be safe, scripts should ignore unknown actions, and if
321 not IPv6-aware, should exit if the environment
322 variable DNSMASQ_IAID is set. The use-case for this is
323 to track netboot/install. Suggestion from Shantanu
324 Gadgil.
326 Update contrib/port-forward/dnsmasq-portforward to reflect
327 the above.
329 Set the environment variable DNSMASQ_LOG_DHCP when running
330 the script id --log-dhcp is in effect, so that script can
331 taylor their logging verbosity. Suggestion from Malte
332 Forkel.
334 Arrange that addresses specified with --listen-address
335 work even if there is no interface carrying the
336 address. This is chiefly useful for IPv4 loopback
337 addresses, where any address in 127.0.0.0/8 is a valid
338 loopback address, but normally only 127.0.0.1 appears on
339 the lo interface. Thanks to Mathieu Trudel-Lapierre for
340 the idea and initial patch.
342 Fix crash, introduced in 2.60, when a DHCPINFORM is
343 received from a network which has no valid dhcp-range.
344 Thanks to Stephane Glondu for the bug report.
346 Add a new DHCP lease time keyword, "deprecated" for
347 --dhcp-range. This is only valid for IPv6, and sets the
348 preffered lease time for both DHCP and RA to zero. The
349 effect is that clients can continue to use the address
350 for existing connections, but new connections will use
351 other addresses, if they exist. This makes hitless
352 renumbering at least possible.
354 Fix bug in address6_available() which caused DHCPv6 lease
355 aquisition to fail if more than one dhcp-range in use.
357 Provide RDNSS and DNSSL data in router advertisements,
358 using the settings provided for DHCP options
359 option6:domain-search and option6:dns-server.
361 Tweak logo/favicon.ico to add some transparency. Thanks to
362 SamLT for work on this.
364 Don't cache data from non-recursive nameservers, since it
365 may erroneously look like a valid CNAME to a non-exitant
366 name. Thanks to Ben Winslow for finding this.
368 Call SO_BINDTODEVICE on the DHCP socket(s) when doing DHCP
369 on exactly one interface and --bind-interfaces is set. This
370 makes the OpenStack use-case of one dnsmasq per virtual
371 interface work. This is only available on Linux; it's not
372 supported on other platforms. Thanks to Vishvananda Ishaya
373 and the OpenStack team for the suggestion.
375 Updated French translation. Thanks to Gildas Le Nadan.
377 Give correct from-cache answers to explict CNAME queries.
378 Thanks to Rob Zwissler for spotting this.
380 Add --tftp-lowercase option. Thanks to Oliver Rath for the
381 patch.
383 Ensure that the DBus DhcpLeaseUpdated events are generated
384 when a lease goes through INIT_REBOOT state, even if the
385 dhcp-script is not in use. Thanks to Antoaneta-Ecaterina
386 Ene for the patch.
388 Fix failure of TFTP over IPv4 on OpenBSD platform. Thanks
389 to Brad Smith for spotting this.
392 version 2.60
393 Fix compilation problem in Mac OS X Lion. Thanks to Olaf
394 Flebbe for the patch.
396 Fix DHCP when using --listen-address with an IP address
397 which is not the primary address of an interface.
399 Add --dhcp-client-update option.
401 Add Lua integration. Dnsmasq can now execute a DHCP
402 lease-change script written in Lua. This needs to be
403 enabled at compile time by setting HAVE_LUASCRIPT in
404 src/config.h or running "make COPTS=-DHAVE_LUASCRIPT"
405 Thanks to Jan-Piet Mens for the idea and proof-of-concept
406 implementation.
408 Tidied src/config.h to distinguish between
409 platform-dependent compile-time options which are selected
410 automatically, and builder-selectable compile time
411 options. Document the latter better, and describe how to
412 set them from the make command line.
414 Tidied up IPPROTO_IP/SOL_IP (and IPv6 equivalent)
415 confusion. IPPROTO_IP works everywhere now.
417 Set TOS on DHCP sockets, this improves things on busy
418 wireless networks. Thanks to Dave Taht for the patch.
420 Determine VERSION automatically based on git magic:
421 release tags or hash values.
423 Improve start-up speed when reading large hosts files
424 containing many distinct addresses.
426 Fix problem if dnsmasq is started without the stdin,
427 stdout and stderr file descriptors open. This can manifest
428 itself as 100% CPU use. Thanks to Chris Moore for finding
429 this.
431 Fix shell-scripting bug in bld/pkg-wrapper. Thanks to
432 Mark Mitchell for the patch.
434 Allow the TFP server or boot server in --pxe-service, to
435 be a domain name instead of an IP address. This allows for
436 round-robin to multiple servers, in the same way as
437 --dhcp-boot. A good suggestion from Cristiano Cumer.
439 Support BUILDDIR variable in the Makefile. Allows builds
440 for multiple archs from the same source tree with eg.
441 make BUILDDIR=linux (relative to dnsmasq tree)
442 make BUILDDIR=/tmp/openbsd (absolute path)
443 If BUILDDIR is not set, compilation happens in the src
444 directory, as before. Suggestion from Mark Mitchell.
446 Support DHCPv6. Support is there for the sort of things
447 the existing v4 server does, including tags, options,
448 static addresses and relay support. Missing is prefix
449 delegation, which is probably not required in the dnsmasq
450 niche, and an easy way to accept prefix delegations from
451 an upstream DHCPv6 server, which is. Future plans include
452 support for DHCPv6 router option and MAC address option
453 (to make selecting clients by MAC address work like IPv4).
454 These will be added as the standards mature.
455 This code has been tested, but this is the first release,
456 so don't bet the farm on it just yet. Many thanks to all
457 testers who have got it this far.
459 Support IPv6 router advertisements. This is a
460 simple-minded implementation, aimed at providing the
461 vestigial RA needed to go alongside IPv6. Is picks up
462 configuration from the DHCPv6 conf, and should just need
463 enabling with --enable-ra.
465 Fix long-standing wrinkle with --localise-queries that
466 could result in wrong answers when DNS packets arrive
467 via an interface other than the expected one. Thanks to
468 Lorenzo Milesi and John Hanks for spotting this one.
470 Update French translation. Thanks to Gildas Le Nadan.
472 Update Polish translation. Thanks to Jan Psota.
475 version 2.59
476 Fix regression in 2.58 which caused failure to start up
477 with some combinations of dnsmasq config and IPv6 kernel
478 network config. Thanks to Brielle Bruns for the bug
479 report.
481 Improve dnsmasq's behaviour when network interfaces are
482 still doing duplicate address detection (DAD). Previously,
483 dnsmasq would wait up to 20 seconds at start-up for the
484 DAD state to terminate. This is broken for bridge
485 interfaces on recent Linux kernels, which don't start DAD
486 until the bridge comes up, and so can take arbitrary
487 time. The new behaviour lets dnsmasq poll for an arbitrary
488 time whilst providing service on other interfaces. Thanks
489 to Stephen Hemminger for pointing out the problem.
492 version 2.58
493 Provide a definition of the SA_SIZE macro where it's
494 missing. Fixes build failure on openBSD.
496 Don't include a zero terminator at the end of messages
497 sent to /dev/log when /dev/log is a datagram socket.
498 Thanks to Didier Rabound for spotting the problem.
500 Add --dhcp-sequential-ip flag, to force allocation of IP
501 addresses in ascending order. Note that the default
502 pseudo-random mode is in general better but some
503 server-deployment applications need this.
505 Fix problem where a server-id of 0.0.0.0 is sent to a
506 client when a dhcp-relay is in use if a client renews a
507 lease after dnsmasq restart and before any clients on the
508 subnet get a new lease. Thanks to Mike Ruiz for assistance
509 in chasing this one down.
511 Don't return NXDOMAIN to an AAAA query if we have CNAME
512 which points to an A record only: NODATA is the correct
513 reply in this case. Thanks to Tom Fernandes for spotting
514 the problem.
516 Relax the need to supply a netmask in --dhcp-range for
517 networks which use a DHCP relay. Whilst this is still
518 desireable, in the absence of a netmask dnsmasq will use
519 a default based on the class (A, B, or C) of the address.
520 This should at least remove a cause of mysterious failure
521 for people using RFC1918 addresses and relays.
523 Add support for Linux conntrack connection marking. If
524 enabled with --conntrack, the connection mark for incoming
525 DNS queries will be copied to the outgoing connections
526 used to answer those queries. This allows clever firewall
527 and accounting stuff. Only available if dnsmasq is
528 compiled with HAVE_CONNTRACK and adds a dependency on
529 libnetfilter-conntrack. Thanks to Ed Wildgoose for the
530 initial idea, testing and sponsorship of this function.
532 Provide a sane error message when someone attempts to
533 match a tag in --dhcp-host.
535 Tweak the behaviour of --domain-needed, to avoid problems
536 with recursive nameservers downstream of dnsmasq. The new
537 behaviour only stops A and AAAA queries, and returns
538 NODATA rather than NXDOMAIN replies.
540 Efficiency fix for very large DHCP configurations, thanks
541 to James Gartrell and Mike Ruiz for help with this.
543 Allow the TFTP-server address in --dhcp-boot to be a
544 domain-name which is looked up in /etc/hosts. This can
545 give multiple IP addresses which are used round-robin,
546 thus doing TFTP server load-balancing. Thanks to Sushil
547 Agrawal for the patch.
549 When two tagged dhcp-options for a particular option
550 number are both valid, use the one which is valid without
551 a tag from the dhcp-range. Allows overriding of the value
552 of a DHCP option for a particular host as well as
553 per-network values. So
554 --dhcp-range=set:interface1,......
555 --dhcp-host=set:myhost,.....
556 --dhcp-option=tag:interface1,option:nis-domain,"domain1"
557 --dhcp-option=tag:myhost,option:nis-domain,"domain2"
558 will set the NIS-domain to domain1 for hosts in the range, but
559 override that to domain2 for a particular host.
561 Fix bug which resulted in truncated files and timeouts for
562 some TFTP transfers. The bug only occurs with netascii
563 transfers and needs an unfortunate relationship between
564 file size, blocksize and the number of newlines in the
565 last block before it manifests itself. Many thanks to
566 Alkis Georgopoulos for spotting the problem and providing
567 a comprehensive test-case.
569 Fix regression in TFTP server on *BSD platforms introduced
570 in version 2.56, due to confusion with sockaddr
571 length. Many thanks to Loic Pefferkorn for finding this.
573 Support scope-ids in IPv6 addresses of nameservers from
574 /etc/resolv.conf and in --server options. Eg
575 nameserver fe80::202:a412:4512:7bbf%eth0 or
576 server=fe80::202:a412:4512:7bbf%eth0. Thanks to
577 Michael Stapelberg for the suggestion.
579 Update Polish translation, thanks to Jan Psota.
581 Update French translation. Thanks to Gildas Le Nadan.
584 version 2.57
585 Add patches to allow build under Android.
587 Provide our own header for the DNS protocol, rather than
588 relying on arpa/nameser.h. This has proved more or less
589 defective over the years and the final straw is that it's
590 effectively empty on Android.
592 Fix regression in 2.56 which caused hex constants in
593 configuration to be rejected if they contain the '*'
594 wildcard.
596 Correct wrong casts of arguments to ctype.h functions,
597 isdigit(), isxdigit() etc. Thanks to Matthias Andree for
598 spotting this.
600 Allow build with IDN support independently from i18n.
601 IDN support continues to be included automatically
602 when i18n is included.
603 'make COPTS=-DHAVE_IDN' is the magic incantation.
605 Modify check on extraneous command line junk (added in
606 2.56) so that it doesn't complain about extra _empty_
607 arguments. Otherwise this breaks libvirt.
610 version 2.56
611 Add a patch to allow dnsmasq to get interface names right in a
612 Solaris zone. Thanks to Dj Padzensky for this.
614 Improve data-type parsing heuristics so that
615 --dhcp-option=option:domain-search,.
616 treats the value as a string and not an IP address.
617 Thanks to Clemens Fischer for spotting that.
619 Add IPv6 support to the TFTP server. Many thanks to Jan
620 'RedBully' Seiffert for the patches.
622 Log DNS queries at level LOG_INFO, rather then
623 LOG_DEBUG. This makes things consistent with DHCP
624 logging. Thanks to Adam Pribyl for spotting the problem.
626 Ensure that dnsmasq terminates cleanly when using
627 --syslog-async even if it cannot make a connection to the
628 syslogd.
630 Add --add-mac option. This is to support currently
631 experimental DNS filtering facilities. Thanks to Benjamin
632 Petrin for the orignal patch.
634 Fix bug which meant that tags were ignored in dhcp-range
635 configuration specifying PXE-proxy service. Thanks to
636 Cristiano Cumer for spotting this.
638 Raise an error if there is extra junk, not part of an
639 option, on the command line.
641 Flag a couple of log messages in cache.c as coming from
642 the DHCP subsystem. Thanks to Olaf Westrik for the patch.
644 Omit timestamps from logs when a) logging to stderr and
645 b) --keep-in-forground is set. The logging facility on the
646 other end of stderr can be assumned to supply them. Thanks
647 to John Hallam for the patch.
649 Don't complain about strings longer than 255 characters in
650 --txt-record, just split the long strings into 255
651 character chunks instead.
653 Fix crash on double-free. This bug can only happen when
654 dhcp-script is in use and then only in rare circumstances
655 triggered by high DHCP transaction rate and a slow
656 script. Thanks to Ferenc Wagner for finding the problem.
658 Only log that a file has been sent by TFTP after the
659 transfer has completed succesfully.
661 A good suggestion from Ferenc Wagner: extend
662 the --domain option to allow this sort of thing:
663 --domain=thekelleys.org.uk,192.168.0.0/24,local
664 which automatically creates
665 --local=/thekelleys.org.uk/
666 --local=/0.168.192.in-addr.arpa/
668 Tighten up syntax checking of hex contants in the config
669 file. Thanks to Fred Damen for spotting this.
671 Add dnsmasq logo/icon, contributed by Justin Swift. Many
672 thanks for that.
674 Never cache DNS replies which have the 'cd' bit set, or
675 which result from queries forwarded with the 'cd' bit
676 set. The 'cd' bit instructs a DNSSEC validating server
677 upstream to ignore signature failures and return replies
678 anyway. Without this change it's possible to pollute the
679 dnsmasq cache with bad data by making a query with the
680 'cd' bit set and subsequent queries would return this data
681 without its being marked as suspect. Thanks to Anders
682 Kaseorg for pointing out this problem.
684 Add --proxy-dnssec flag, for compliance with RFC
685 4035. Dnsmasq will now clear the 'ad' bit in answers returned
686 from upstream validating nameservers unless this option is
687 set.
689 Allow a filename of "-" for --conf-file to read
690 stdin. Suggestion from Timothy Redaelli.
692 Rotate the order of SRV records in replies, to provide
693 round-robin load balancing when all the priorities are
694 equal. Thanks to Peter McKinney for the suggestion.
696 Edit
697 contrib/MacOSX-launchd/uk.org.thekelleys.dnsmasq.plist
698 so that it doesn't log all queries to a file by
699 default. Thanks again to Peter McKinney.
701 By default, setting an IPv4 address for a domain but not
702 an IPv6 address causes dnsmasq to return
703 an NODATA reply for IPv6 (or vice-versa). So
704 --address=/google.com/1.2.3.4 stops IPv6 queries for
705 *google.com from being forwarded. Make it possible to
706 override this behaviour by defining the sematics if the
707 same domain appears in both --server and --address.
708 In that case, the --address has priority for the address
709 family in which is appears, but the --server has priority
710 of the address family which doesn't appear in --adddress
711 So:
712 --address=/google.com/1.2.3.4
713 --server=/google.com/#
714 will return 1.2.3.4 for IPv4 queries for *.google.com but
715 forward IPv6 queries to the normal upstream nameserver.
716 Similarly when setting an IPv6 address
717 only this will allow forwarding of IPv4 queries. Thanks to
718 William for pointing out the need for this.
720 Allow more than one --dhcp-optsfile and --dhcp-hostsfile
721 and make them understand directories as arguments in the
722 same way as --addn-hosts. Suggestion from John Hanks.
724 Ignore rebinding requests for leases we don't know
725 about. Rebind is broadcast, so we might get to overhear a
726 request meant for another DHCP server. NAKing this is
727 wrong. Thanks to Brad D'Hondt for assistance with this.
729 Fix cosmetic bug which produced strange output when
730 dumping cache statistics with some configurations. Thanks
731 to Fedor Kozhevnikov for spotting this.
734 version 2.55
735 Fix crash when /etc/ethers is in use. Thanks to
736 Gianluigi Tiesi for finding this.
738 Fix crash in netlink_multicast(). Thanks to Arno Wald for
739 finding this one.
741 Allow the empty domain "." in dhcp domain-search (119)
742 options.
745 version 2.54
746 There is no version 2.54 to avoid confusion with 2.53,
747 which incorrectly identifies itself as 2.54.
750 version 2.53
751 Fix failure to compile on Debian/kFreeBSD. Thanks to
752 Axel Beckert and Petr Salinger.
754 Fix code to avoid scary strict-aliasing warnings
755 generated by gcc 4.4.
757 Added FAQ entry warning about DHCP failures with Vista
758 when firewalls block 255.255.255.255.
760 Fixed bug which caused bad things to happen if a
761 resolv.conf file which exists is subsequently removed.
762 Thanks to Nikolai Saoukh for the patch.
764 Rationalised the DHCP tag system. Every configuration item
765 which can set a tag does so by adding "set:<tag>" and
766 every configuration item which is conditional on a tag is
767 made so by "tag:<tag>". The NOT operator changes to '!',
768 which is a bit more intuitive too. Dhcp-host directives
769 can set more than one tag now. The old '#' NOT,
770 "net:" prefix and no-prefixes are still honoured, so
771 no existing config file needs to be changed, but
772 the documentation and new-style config files should be
773 much less confusing.
775 Added --tag-if to allow boolean operations on tags.
776 This allows complicated logic to be clearer and more
777 general. A great suggestion from Richard Voigt.
779 Add broadcast/unicast information to DHCP logging.
781 Allow --dhcp-broadcast to be unconditional.
783 Fixed incorrect behaviour with NOT <tag> conditionals in
784 dhcp-options. Thanks to Max Turkewitz for assistance
785 finding this.
787 If we send vendor-class encapsulated options based on the
788 vendor-class supplied by the client, and no explicit
789 vendor-class option is given, echo back the vendor-class
790 from the client.
792 Fix bug which stopped dnsmasq from matching both a
793 circuitid and a remoteid. Thanks to Ignacio Bravo for
794 finding this.
796 Add --dhcp-proxy, which makes it possible to configure
797 dnsmasq to use a DHCP relay agent as a full proxy, with
798 all DHCP messages passing through the proxy. This is
799 useful if the relay adds extra information to the packets
800 it forwards, but cannot be configured with the RFC 5107
801 server-override option.
803 Added interface:<iface name> part to dhcp-range. The
804 semantics of this are very odd at first sight, but it
805 allows a single line of the form
806 dhcp-range=interface:virt0,192.168.0.4,192.168.0.200
807 to be added to dnsmasq configuration which then supplies
808 DHCP and DNS services to that interface, without affecting
809 what services are supplied to other interfaces and
810 irrespective of the existance or lack of
811 interface=<interface>
812 lines elsewhere in the dnsmasq configuration. The idea is
813 that such a line can be added automatically by libvirt
814 or equivalent systems, without disturbing any manual
815 configuration.
817 Similarly to the above, allow --enable-tftp=<interface>
819 Allow a TFTP root to be set separately for requests via
820 different interfaces, --tftp-root=<path>,<interface>
822 Correctly handle and log clashes between CNAMES and
823 DNS names being given to DHCP leases. This fixes a bug
824 which caused nonsense IP addresses to be logged. Thanks to
825 Sergei Zhirikov for finding and analysing the problem.
827 Tweak flush_log so as to avoid leaving the log
828 file in non-blocking mode. O_NONBLOCK is a property of the
829 file, not the process/descriptor.
831 Fix contrib/Solaris10/create_package
832 (/usr/man -> /usr/share/man) Thanks to Vita Batrla.
834 Fix a problem where, if a client got a lease, then went
835 to another subnet and got another lease, then moved back,
836 it couldn't resume the old lease, but would instead get
837 a new address. Thanks to Leonardo Rodrigues for spotting
838 this and testing the fix.
840 Fix weird bug which sometimes omitted certain characters
841 from the start of quoted strings in dhcp-options. Thanks
842 to Dayton Turner for spotting the problem.
844 Add facility to redirect some domains to the standard
845 upstream servers: this allows something like
846 --server=/google.com/1.2.3.4 --server=/www.google.com/#
847 which will send queries for *.google.com to 1.2.3.4,
848 except *www.google.com which will be forwarded as usual.
849 Thanks to AJ Weber for prompting this addition.
851 Improve the hash-algorithm used to generate IP addresses
852 from MAC addresses during initial DHCP address
853 allocation. This improves performance when large numbers
854 of hosts with similar MAC addresses all try and get an IP
855 address at the same time. Thanks to Paul Smith for his
856 work on this.
858 Tweak DHCP code so that --bridge-interface can be used to
859 select which IP alias of an interface should be used for
860 DHCP purposes on Linux. If eth0 has an alias eth0:dhcp
861 then adding --bridge-interface=eth0:dhcp,eth0 will use
862 the address of eth0:dhcp to determine the correct subnet
863 for DHCP address allocation. Thanks to Pawel Golaszewski
864 for prompting this and Eric Cooper for further testing.
866 Add --dhcp-generate-names. Suggestion by Ferenc Wagner.
868 Tweak DNS server selection algorithm when there is more
869 than one server available for a domain, eg.
870 --server=/mydomain/1.1.1.1
871 --server=/mydomain/2.2.2.2
872 Thanks to Alberto Cuesta-Canada for spotting a weakness
873 here.
875 Add --max-ttl. Thanks to Fredrik Ringertz for the patch.
877 Allow --log-facility=- to force all logging to
878 stderr. Suggestion from Clemens Fischer.
880 Fix regression which caused configuration like
881 --address=/.domain.com/1.2.3.4 to be rejected. The dot to the
882 left of the domain has been implied and not required for a
883 long time, but it should be accepted for backward
884 compatibility. Thanks to Andrew Burcin for spotting this.
886 Add --rebind-domain-ok and --rebind-localhost-ok.
887 Suggestion from Clemens Fischer.
889 Log replies to queries of type TXT, when --log-queries
890 is set.
892 Fix compiler warnings when compiled with -DNO_DHCP. Thanks
893 to Shantanu Gadgil for the patch.
895 Updated French translation. Thanks to Gildas Le Nadan.
897 Updated Polish translation. Thanks to Jan Psota.
899 Updated German translation. Thanks to Matthias Andree.
901 Added contrib/static-arp, thanks to Darren Hoo.
903 Fix corruption of the domain when a name from /etc/hosts
904 overrides one supplied by a DHCP client. Thanks to Fedor
905 Kozhevnikov for spotting the problem.
907 Updated Spanish translation. Thanks to Chris Chatham.
910 version 2.52
911 Work around a Linux kernel bug which insists that the
912 length of the option passed to setsockopt must be at least
913 sizeof(int) bytes, even if we're calling SO_BINDTODEVICE
914 and the device name is "lo". Note that this is fixed
915 in kernel 2.6.31, but the workaround is harmless and
916 allows earlier kernels to be used. Also fix dnsmasq
917 bug which reported the wrong address when this failed.
918 Thanks to Fedor for finding this.
920 The API for IPv6 PKTINFO changed around Linux kernel
921 2.6.14. Workaround the case where dnsmasq is compiled
922 against newer headers, but then run on an old kernel:
923 necessary for some *WRT distros.
925 Re-read the set of network interfaces when re-loading
926 /etc/resolv.conf if --bind-interfaces is not set. This
927 handles the case that loopback interfaces do not exist
928 when dnsmasq is first started.
930 Tweak the PXE code to support port 4011. This should
931 reduce broadcasts and make things more reliable when other
932 servers are around. It also improves inter-operability
933 with certain clients.
935 Make a pxe-service configuration with no filename or boot
936 service type legal: this does a local boot. eg.
937 pxe-service=x86PC, "Local boot"
939 Be more conservative in detecting "A for A"
940 queries. Dnsmasq checks if the name in a type=A query looks
941 like a dotted-quad IP address and answers the query itself
942 if so, rather than forwarding it. Previously dnsmasq
943 relied in the library function inet_addr() to convert
944 addresses, and that will accept some things which are
945 confusing in this context, like 1.2.3 or even just
946 1234. Now we only do A for A processing for four decimal
947 numbers delimited by dots.
949 A couple of tweaks to fix compilation on Solaris. Thanks
950 to Joel Macklow for help with this.
952 Another Solaris compilation tweak, needed for Solaris
953 2009.06. Thanks to Lee Essen for that.
955 Added extract packaging stuff from Lee Essen to
956 contrib/Solaris10.
958 Increased the default limit on number of leases to 1000
959 (from 150). This is mainly a defence against DoS attacks,
960 and for the average "one for two class C networks"
961 installation, IP address exhaustion does that just as
962 well. Making the limit greater than the number of IP
963 addresses available in such an installation removes a
964 surprise which otherwise can catch people out.
966 Removed extraneous trailing space in the value of the
967 DNSMASQ_TIME_REMAINING DNSMASQ_LEASE_LENGTH and
968 DNSMASQ_LEASE_EXPIRES environment variables. Thanks to
969 Gildas Le Nadan for spotting this.
971 Provide the network-id tags for a DHCP transaction to
972 the lease-change script in the environment variable
973 DNSMASQ_TAGS. A good suggestion from Gildas Le Nadan.
975 Add support for RFC3925 "Vendor-Identifying Vendor
976 Options". The syntax looks like this:
977 --dhcp-option=vi-encap:<enterprise number>, .........
979 Add support to --dhcp-match to allow matching against
980 RFC3925 "Vendor-Identifying Vendor Classes". The syntax
981 looks like this:
982 --dhcp-match=tag,vi-encap<enterprise number>, <value>
984 Add some application specific code to assist in
985 implementing the Broadband forum TR069 CPE-WAN
986 specification. The details are in contrib/CPE-WAN/README
988 Increase the default DNS packet size limit to 4096, as
989 recommended by RFC5625 section 4.4.3. This can be
990 reconfigured using --edns-packet-max if needed. Thanks to
991 Francis Dupont for pointing this out.
993 Rewrite query-ids even for TSIG signed packets, since
994 this is allowed by RFC5625 section 4.5.
996 Use getopt_long by default on OS X. It has been supported
997 since version 10.3.0. Thanks to Arek Dreyer for spotting
998 this.
1000 Added up-to-date startup configuration for MacOSX/launchd
1001 in contrib/MacOSX-launchd. Thanks to Arek Dreyer for
1002 providing this.
1004 Fix link error when including Dbus but excluding DHCP.
1005 Thanks to Oschtan for the bug report.
1007 Updated French translation. Thanks to Gildas Le Nadan.
1009 Updated Polish translation. Thanks to Jan Psota.
1011 Updated Spanish translation. Thanks to Chris Chatham.
1013 Fixed confusion about domains, when looking up DHCP hosts
1014 in /etc/hosts. This could cause spurious "Ignoring
1015 domain..." messages. Thanks to Fedor Kozhevnikov for
1016 finding and analysing the problem.
1019 version 2.51
1020 Add support for internationalised DNS. Non-ASCII characters
1021 in domain names found in /etc/hosts, /etc/ethers and
1022 /etc/dnsmasq.conf will be correctly handled by translation to
1023 punycode, as specified in RFC3490. This function is only
1024 available if dnsmasq is compiled with internationalisation
1025 support, and adds a dependency on GNU libidn. Without i18n
1026 support, dnsmasq continues to be compilable with just
1027 standard tools. Thanks to Yves Dorfsman for the
1028 suggestion.
1030 Add two more environment variables for lease-change scripts:
1031 First, DNSMASQ_SUPPLIED_HOSTNAME; this is set to the hostname
1032 supplied by a client, even if the actual hostname used is
1033 over-ridden by dhcp-host or dhcp-ignore-names directives.
1034 Also DNSMASQ_RELAY_ADDRESS which gives the address of
1035 a DHCP relay, if used.
1036 Suggestions from Michael Rack.
1038 Fix regression which broke echo of relay-agent
1039 options. Thanks to Michael Rack for spotting this.
1041 Don't treat option 67 as being interchangeable with
1042 dhcp-boot parameters if it's specified as
1043 dhcp-option-force.
1045 Make the code to call scripts on lease-change compile-time
1046 optional. It can be switched off by editing src/config.h
1047 or building with "make COPTS=-DNO_SCRIPT".
1049 Make the TFTP server cope with filenames from Windows/DOS
1050 which use '\' as pathname separator. Thanks to Ralf for
1051 the patch.
1053 Updated Polish translation. Thanks to Jan Psota.
1055 Warn if an IP address is duplicated in /etc/ethers. Thanks
1056 to Felix Schwarz for pointing this out.
1058 Teach --conf-dir to take an option list of file suffices
1059 which will be ignored when scanning the directory. Useful
1060 for backup files etc. Thanks to Helmut Hullen for the
1061 suggestion.
1063 Add new DHCP option named tftpserver-address, which
1064 corresponds to the third argument of dhcp-boot. This
1065 allows the complete functionality of dhcp-boot to be
1066 replicated with dhcp-option. Useful when using
1067 dhcp-optsfile.
1069 Test which upstream nameserver to use every 10 seconds
1070 or 50 queries and not just when a query times out and
1071 is retried. This should improve performance when there
1072 is a slow nameserver in the list. Thanks to Joe for the
1073 suggestion.
1075 Don't do any PXE processing, even for clients with the
1076 correct vendorclass, unless at least one pxe-prompt or
1077 pxe-service option is given. This stops dnsmasq
1078 interfering with proxy PXE subsystems when it is just
1079 the DHCP server. Thanks to Spencer Clark for spotting this.
1081 Limit the blocksize used for TFTP transfers to a value
1082 which avoids packet fragmentation, based on the MTU of the
1083 local interface. Many netboot ROMs can't cope with
1084 fragmented packets.
1086 Honour dhcp-ignore configuration for PXE and proxy-PXE
1087 requests. Thanks to Niels Basjes for the bug report.
1089 Updated French translation. Thanks to Gildas Le Nadan.
1092 version 2.50
1093 Fix security problem which allowed any host permitted to
1094 do TFTP to possibly compromise dnsmasq by remote buffer
1095 overflow when TFTP enabled. Thanks to Core Security
1096 Technologies and Iván Arce, Pablo Hernán Jorge, Alejandro
1097 Pablo Rodriguez, Martín Coco, Alberto Soliño Testa and
1098 Pablo Annetta. This problem has Bugtraq id: 36121
1099 and CVE: 2009-2957
1101 Fix a problem which allowed a malicious TFTP client to
1102 crash dnsmasq. Thanks to Steve Grubb at Red Hat for
1103 spotting this. This problem has Bugtraq id: 36120 and
1104 CVE: 2009-2958
1107 version 2.49
1108 Fix regression in 2.48 which disables the lease-change
1109 script. Thanks to Jose Luis Duran for spotting this.
1111 Log TFTP "file not found" errors. These were not logged,
1112 since a normal PXELinux boot generates many of them, but
1113 the lack of the messages seems to be more confusing than
1114 routinely seeing them when there is no real error.
1116 Update Spanish translation. Thanks to Chris Chatham.
1119 version 2.48
1120 Archived the extensive, backwards, changelog to
1121 CHANGELOG.archive. The current changelog now runs from
1122 version 2.43 and runs conventionally.
1124 Fixed bug which broke binding of servers to physical
1125 interfaces when interface names were longer than four
1126 characters. Thanks to MURASE Katsunori for the patch.
1128 Fixed netlink code to check that messages come from the
1129 correct source, and not another userspace process. Thanks
1130 to Steve Grubb for the patch.
1132 Maintainability drive: removed bug and missing feature
1133 workarounds for some old platforms. Solaris 9, OpenBSD
1134 older than 4.1, Glibc older than 2.2, Linux 2.2.x and
1135 DBus older than 1.1.x are no longer supported.
1137 Don't read included configuration files more than once:
1138 allows complex configuration structures without problems.
1140 Mark log messages from the various subsystems in dnsmasq:
1141 messages from the DHCP subsystem now have the ident string
1142 "dnsmasq-dhcp" and messages from TFTP have ident
1143 "dnsmasq-tftp". Thanks to Olaf Westrik for the patch.
1145 Fix possible infinite DHCP protocol loop when an IP
1146 address nailed to a hostname (not a MAC address) and a
1147 host sometimes provides the name, sometimes not.
1149 Allow --addn-hosts to take a directory: all the files
1150 in the directory are read. Thanks to Phil Cornelius for
1151 the suggestion.
1153 Support --bridge-interface on all platforms, not just BSD.
1155 Added support for advanced PXE functions. It's now
1156 possible to define a prompt and menu options which will
1157 be displayed when a client PXE boots. It's also possible to
1158 hand-off booting to other boot servers. Proxy-DHCP, where
1159 dnsmasq just supplies the PXE information and another DHCP
1160 server does address allocation, is also allowed. See the
1161 --pxe-prompt and --pxe-service keywords. Thanks to
1162 Alkis Georgopoulos for the suggestion and Guilherme Moro
1163 and Michael Brown for assistance.
1165 Improvements to DHCP logging. Thanks to Tom Metro for
1166 useful suggestions.
1168 Add ability to build dnsmasq without DHCP support. To do
1169 this, edit src/config.h or build with
1170 "make COPTS=-DNO_DHCP". Thanks to Mahavir Jain for the patch.
1172 Added --test command-line switch - syntax check
1173 configuration files only.
1175 Updated French translation. Thanks to Gildas Le Nadan.
1178 version 2.47
1179 Updated French translation. Thanks to Gildas Le Nadan.
1181 Fixed interface enumeration code to work on NetBSD
1182 5.0. Thanks to Roy Marples for the patch.
1184 Updated config.h to use the same location for the lease
1185 file on NetBSD as the other *BSD variants. Also allow
1186 LEASEFILE and CONFFILE symbols to be overriden in CFLAGS.
1188 Handle duplicate address detection on IPv6 more
1189 intelligently. In IPv6, an interface can have an address
1190 which is not usable, because it is still undergoing DAD
1191 (such addresses are marked "tentative"). Attempting to
1192 bind to an address in this state returns an error,
1193 EADDRNOTAVAIL. Previously, on getting such an error,
1194 dnsmasq would silently abandon the address, and never
1195 listen on it. Now, it retries once per second for 20
1196 seconds before generating a fatal error. 20 seconds should
1197 be long enough for any DAD process to complete, but can be
1198 adjusted in src/config.h if necessary. Thanks to Martin
1199 Krafft for the bug report.
1201 Add DBus introspection. Patch from Jeremy Laine.
1203 Update Dbus configuration file. Patch from Colin Walters.
1204 Fix for this bug:
1205 http://bugs.freedesktop.org/show_bug.cgi?id=18961
1207 Support arbitrarily encapsulated DHCP options, suggestion
1208 and initial patch from Samium Gromoff. This is useful for
1209 (eg) gPXE, which expect all its private options to be
1210 encapsulated inside a single option 175. So, eg,
1212 dhcp-option = encap:175, 190, "iscsi-client0"
1213 dhcp-option = encap:175, 191, "iscsi-client0-secret"
1215 will provide iSCSI parameters to gPXE.
1217 Enhance --dhcp-match to allow testing of the contents of a
1218 client-sent option, as well as its presence. This
1219 application in mind for this is RFC 4578
1220 client-architecture specifiers, but it's generally useful.
1221 Joey Korkames suggested the enhancement.
1223 Move from using the IP_XMIT_IF ioctl to IP_BOUND_IF on
1224 OpenSolaris. Thanks to Bastian Machek for the heads-up.
1226 No longer complain about blank lines in
1227 /etc/ethers. Thanks to Jon Nelson for the patch.
1229 Fix binding of servers to physical devices, eg
1230 --server=/domain/1.2.3.4@eth0 which was broken from 2.43
1231 onwards unless --query-port=0 set. Thanks to Peter Naulls
1232 for the bug report.
1234 Reply to DHCPINFORM requests even when the supplied ciaddr
1235 doesn't fall in any dhcp-range. In this case it's not
1236 possible to supply a complete configuration, but
1237 individually-configured options (eg PAC) may be useful.
1239 Allow the source address of an alias to be a range:
1240 --alias=192.168.0.0,10.0.0.0,255.255.255.0 maps the whole
1241 subnet 192.168.0.0->192.168.0.255 to 10.0.0.0->10.0.0.255,
1242 as before.
1243 --alias=192.168.0.10-192.168.0.40,10.0.0.0,255.255.255.0
1244 maps only the 192.168.0.10->192.168.0.40 region. Thanks to
1245 Ib Uhrskov for the suggestion.
1247 Don't dynamically allocate DHCP addresses which may break
1248 Windows. Addresses which end in .255 or .0 are broken in
1249 Windows even when using supernetting.
1250 --dhcp-range=192.168.0.1,192.168.1.254,255,255,254.0 means
1251 192.168.0.255 is a valid IP address, but not for Windows.
1252 See Microsoft KB281579. We therefore no longer allocate
1253 these addresses to avoid hard-to-diagnose problems.
1255 Update Polish translation. Thanks to Jan Psota.
1257 Delete the PID-file when dnsmasq shuts down. Note that by
1258 this time, dnsmasq is normally not running as root, so
1259 this will fail if the PID-file is stored in a root-owned
1260 directory; such failure is silently ignored. To take
1261 advantage of this feature, the PID-file must be stored in a
1262 directory owned and write-able by the user running
1263 dnsmasq.
1266 version 2.46
1267 Allow --bootp-dynamic to take a netid tag, so that it may
1268 be selectively enabled. Thanks to Olaf Westrik for the
1269 suggestion.
1271 Remove ISC-leasefile reading code. This has been
1272 deprecated for a long time, and last time I removed it, it
1273 ended up going back by request of one user. This time,
1274 it's gone for good; otherwise it would need to be
1275 re-worked to support multiple domains (see below).
1277 Support DHCP clients in multiple DNS domains. This is a
1278 long-standing request. Clients are assigned to a domain
1279 based in their IP address.
1281 Add --dhcp-fqdn flag, which changes behaviour if DNS names
1282 assigned to DHCP clients. When this is set, there must be
1283 a domain associated with each client, and only
1284 fully-qualified domain names are added to the DNS. The
1285 advantage is that the only the FQDN needs to be unique,
1286 so that two or more DHCP clients can share a hostname, as
1287 long as they are in different domains.
1289 Set environment variable DNSMASQ_DOMAIN when invoking
1290 lease-change script. This may be useful information to
1291 have now that it's variable.
1293 Tighten up data-checking code for DNS packet
1294 handling. Thanks to Steve Dodd who found certain illegal
1295 packets which could crash dnsmasq. No memory overwrite was
1296 possible, so this is not a security issue beyond the DoS
1297 potential.
1299 Update example config dhcp option 47, the previous
1300 suggestion generated an illegal, zero-length,
1301 option. Thanks to Matthias Andree for finding this.
1303 Rewrite hosts-file reading code to remove the limit of
1304 1024 characters per line. John C Meuser found this.
1306 Create a net-id tag with the name of the interface on
1307 which the DHCP request was received.
1309 Fixed minor memory leak in DBus code, thanks to Jeremy
1310 Laine for the patch.
1312 Emit DBus signals as the DHCP lease database
1313 changes. Thanks to Jeremy Laine for the patch.
1315 Allow for more that one MAC address in a dhcp-host
1316 line. This configuration tells dnsmasq that it's OK to
1317 abandon a DHCP lease of the fixed address to one MAC
1318 address, if another MAC address in the dhcp-host statement
1319 asks for an address. This is useful to give a fixed
1320 address to a host which has two network interfaces
1321 (say, a laptop with wired and wireless interfaces.)
1322 It's very important to ensure that only one interface
1323 at a time is up, since dnsmasq abandons the first lease
1324 and re-uses the address before the leased time has
1325 elapsed. John Gray suggested this.
1327 Tweak the response to a DHCP request packet with a wrong
1328 server-id when --dhcp-authoritative is set; dnsmasq now
1329 returns a DHCPNAK, rather than silently ignoring the
1330 packet. Thanks to Chris Marget for spotting this
1331 improvement.
1333 Add --cname option. This provides a limited alias
1334 function, usable for DHCP names. Thanks to AJ Weber for
1335 suggestions on this.
1337 Updated contrib/webmin with latest version from Neil
1338 Fisher.
1340 Updated Polish translation. Thanks to Jan Psota.
1342 Correct the text names for DHCP options 64 and 65 to be
1343 "nis+-domain" and "nis+-servers".
1345 Updated Spanish translation. Thanks to Chris Chatham.
1347 Force re-reading of /etc/resolv.conf when an "interface
1348 up" event occurs.
1351 version 2.45
1352 Fix total DNS failure in release 2.44 unless --min-port
1353 specified. Thanks to Steven Barth and Grant Coady for
1354 bugreport. Also reject out-of-range port spec, which could
1355 break things too: suggestion from Gilles Espinasse.
1358 version 2.44
1359 Fix crash when unknown client attempts to renew a DHCP
1360 lease, problem introduced in version 2.43. Thanks to
1361 Carlos Carvalho for help chasing this down.
1363 Fix potential crash when a host which doesn't have a lease
1364 does DHCPINFORM. Again introduced in 2.43. This bug has
1365 never been reported in the wild.
1367 Fix crash in netlink code introduced in 2.43. Thanks to
1368 Jean Wolter for finding this.
1370 Change implementation of min_port to work even if min-port
1371 is large.
1373 Patch to enable compilation of latest Mac OS X. Thanks to
1374 David Gilman.
1376 Update Spanish translation. Thanks to Christopher Chatham.
1379 version 2.43
1380 Updated Polish translation. Thanks to Jan Psota.
1382 Flag errors when configuration options are repeated
1383 illegally.
1385 Further tweaks for GNU/kFreeBSD
1387 Add --no-wrap to msgmerge call - provides nicer .po file
1388 format.
1390 Honour lease-time spec in dhcp-host lines even for
1391 BOOTP. The user is assumed to known what they are doing in
1392 this case. (Hosts without the time spec still get infinite
1393 leases for BOOTP, over-riding the default in the
1394 dhcp-range.) Thanks to Peter Katzmann for uncovering this.
1396 Fix problem matching relay-agent ids. Thanks to Michael
1397 Rack for the bug report.
1399 Add --naptr-record option. Suggestion from Johan
1400 Bergquist.
1402 Implement RFC 5107 server-id-override DHCP relay agent
1403 option.
1405 Apply patches from Stefan Kruger for compilation on
1406 Solaris 10 under Sun studio.
1408 Yet more tweaking of Linux capability code, to suppress
1409 pointless wingeing from kernel 2.6.25 and above.
1411 Improve error checking during startup. Previously, some
1412 errors which occurred during startup would be worked
1413 around, with dnsmasq still starting up. Some were logged,
1414 some silent. Now, they all cause a fatal error and dnsmasq
1415 terminates with a non-zero exit code. The errors are those
1416 associated with changing uid and gid, setting process
1417 capabilities and writing the pidfile. Thanks to Uwe
1418 Gansert and the Suse security team for pointing out
1419 this improvement, and Bill Reimers for good implementation
1420 suggestions.
1422 Provide NO_LARGEFILE compile option to switch off largefile
1423 support when compiling against versions of uclibc which
1424 don't support it. Thanks to Stephane Billiart for the patch.
1426 Implement random source ports for interactions with
1427 upstream nameservers. New spoofing attacks have been found
1428 against nameservers which do not do this, though it is not
1429 clear if dnsmasq is vulnerable, since to doesn't implement
1430 recursion. By default dnsmasq will now use a different
1431 source port (and socket) for each query it sends
1432 upstream. This behaviour can suppressed using the
1433 --query-port option, and the old default behaviour
1434 restored using --query-port=0. Explicit source-port
1435 specifications in --server configs are still honoured.
1437 Replace the random number generator, for better
1438 security. On most BSD systems, dnsmasq uses the
1439 arc4random() RNG, which is secure, but on other platforms,
1440 it relied on the C-library RNG, which may be
1441 guessable and therefore allow spoofing. This release
1442 replaces the libc RNG with the SURF RNG, from Daniel
1443 J. Berstein's DJBDNS package.
1445 Don't attempt to change user or group or set capabilities
1446 if dnsmasq is run as a non-root user. Without this, the
1447 change from soft to hard errors when these fail causes
1448 problems for non-root daemons listening on high
1449 ports. Thanks to Patrick McLean for spotting this.
1451 Updated French translation. Thanks to Gildas Le Nadan.
1454 version 2.42
1455 The changelog for version 2.42 and earlier is
1456 available in CHANGELOG.archive.
