2 Re-write interface discovery code on *BSD to use
3 getifaddrs. This is more portable, more straightforward,
4 and allows us to find the prefix length for IPv6
7 Add ra-names, ra-stateless and slaac keywords for DHCPv6.
8 Dnsmasq can now synthesise AAAA records for dual-stack
9 hosts which get IPv6 addresses via SLAAC. It is also now
10 possible to use SLAAC and stateless DHCPv6, and to
11 tell clients to use SLAAC addresses as well as DHCP ones.
12 Thanks to Dave Taht for help with this.
14 Add --dhcp-duid to allow DUID-EN uids to be used.
16 Explicity send DHCPv6 replies to the correct port, instead
17 of relying on clients to send requests with the correct
18 source address, since at least one client in the wild gets
19 this wrong. Thanks to Conrda Kostecki for help tracking
22 Send a preference value of 255 in DHCPv6 replies when
23 --dhcp-authoritative is in effect. This tells clients not
24 to wait around for other DHCP servers.
26 Better logging of DHCPv6 options.
28 Add --host-record. Thanks to Rob Zwissler for the
31 Invoke the DHCP script with action "tftp" when a TFTP file
32 transfer completes. The size of the file, address to which
33 it was sent and complete pathname are supplied. Note that
34 version 2.60 introduced some script incompatibilties
35 associated with DHCPv6, and this is a further change. To
36 be safe, scripts should ignore unknown actions, and if
37 not IPv6-aware, should exit if the environment
38 variable DNSMASQ_IAID is set. The use-case for this is
39 to track netboot/install. Suggestion from Shantanu
42 Update contrib/port-forward/dnsmasq-portforward to reflect
45 Set the environment variable DNSMASQ_LOG_DHCP when running
46 the script id --log-dhcp is in effect, so that script can
47 taylor their logging verbosity. Suggestion from Malte
50 Arrange that addresses specified with --listen-address
51 work even if there is no interface carrying the
52 address. This is chiefly useful for IPv4 loopback
53 addresses, where any address in 127.0.0.0/8 is a valid
54 loopback address, but normally only 127.0.0.1 appears on
55 the lo interface. Thanks to Mathieu Trudel-Lapierre for
56 the idea and initial patch.
58 Fix crash, introduced in 2.60, when a DHCPINFORM is
59 received from a network which has no valid dhcp-range.
60 Thanks to Stephane Glondu for the bug report.
62 Add a new DHCP lease time keyword, "deprecated" for
63 --dhcp-range. This is only valid for IPv6, and sets the
64 preffered lease time for both DHCP and RA to zero. The
65 effect is that clients can continue to use the address
66 for existing connections, but new connections will use
67 other addresses, if they exist. This makes hitless
68 renumbering at least possible.
70 Fix bug in address6_available() which caused DHCPv6 lease
71 aquistion to fail if more than one dhcp-range in use.
73 Provide RDNSS and DNSSL data in router advertisements,
74 using the settings provided for DHCP options
75 option6:domain-search and option6:dns-server.
77 Tweak logo/favicon.ico to add some transparency. Thanks to
78 SamLT for work on this.
80 Don't cache data from non-recursive nameservers, since it
81 may erroneously look like a valid CNAME to a non-exitant
82 name. Thanks to Ben Winslow for finding this.
86 Fix compilation problem in Mac OS X Lion. Thanks to Olaf
89 Fix DHCP when using --listen-address with an IP address
90 which is not the primary address of an interface.
92 Add --dhcp-client-update option.
94 Add Lua integration. Dnsmasq can now execute a DHCP
95 lease-change script written in Lua. This needs to be
96 enabled at compile time by setting HAVE_LUASCRIPT in
97 src/config.h or running "make COPTS=-DHAVE_LUASCRIPT"
98 Thanks to Jan-Piet Mens for the idea and proof-of-concept
101 Tidied src/config.h to distinguish between
102 platform-dependent compile-time options which are selected
103 automatically, and builder-selectable compile time
104 options. Document the latter better, and describe how to
105 set them from the make command line.
107 Tidied up IPPROTO_IP/SOL_IP (and IPv6 equivalent)
108 confusion. IPPROTO_IP works everywhere now.
110 Set TOS on DHCP sockets, this improves things on busy
111 wireless networks. Thanks to Dave Taht for the patch.
113 Determine VERSION automatically based on git magic:
114 release tags or hash values.
116 Improve start-up speed when reading large hosts files
117 containing many distinct addresses.
119 Fix problem if dnsmasq is started without the stdin,
120 stdout and stderr file descriptors open. This can manifest
121 itself as 100% CPU use. Thanks to Chris Moore for finding
124 Fix shell-scripting bug in bld/pkg-wrapper. Thanks to
125 Mark Mitchell for the patch.
127 Allow the TFP server or boot server in --pxe-service, to
128 be a domain name instead of an IP address. This allows for
129 round-robin to multiple servers, in the same way as
130 --dhcp-boot. A good suggestion from Cristiano Cumer.
132 Support BUILDDIR variable in the Makefile. Allows builds
133 for multiple archs from the same source tree with eg.
134 make BUILDDIR=linux (relative to dnsmasq tree)
135 make BUILDDIR=/tmp/openbsd (absolute path)
136 If BUILDDIR is not set, compilation happens in the src
137 directory, as before. Suggestion from Mark Mitchell.
139 Support DHCPv6. Support is there for the sort of things
140 the existing v4 server does, including tags, options,
141 static addresses and relay support. Missing is prefix
142 delegation, which is probably not required in the dnsmasq
143 niche, and an easy way to accept prefix delegations from
144 an upstream DHCPv6 server, which is. Future plans include
145 support for DHCPv6 router option and MAC address option
146 (to make selecting clients by MAC address work like IPv4).
147 These will be added as the standards mature.
148 This code has been tested, but this is the first release,
149 so don't bet the farm on it just yet. Many thanks to all
150 testers who have got it this far.
152 Support IPv6 router advertisements. This is a
153 simple-minded implementation, aimed at providing the
154 vestigial RA needed to go alongside IPv6. Is picks up
155 configuration from the DHCPv6 conf, and should just need
156 enabling with --enable-ra.
158 Fix long-standing wrinkle with --localise-queries that
159 could result in wrong answers when DNS packets arrive
160 via an interface other than the expected one. Thanks to
161 Lorenzo Milesi and John Hanks for spotting this one.
163 Update French translation. Thanks to Gildas Le Nadan.
165 Update Polish translation. Thanks to Jan Psota.
169 Fix regression in 2.58 which caused failure to start up
170 with some combinations of dnsmasq config and IPv6 kernel
171 network config. Thanks to Brielle Bruns for the bug
174 Improve dnsmasq's behaviour when network interfaces are
175 still doing duplicate address detection (DAD). Previously,
176 dnsmasq would wait up to 20 seconds at start-up for the
177 DAD state to terminate. This is broken for bridge
178 interfaces on recent Linux kernels, which don't start DAD
179 until the bridge comes up, and so can take arbitrary
180 time. The new behaviour lets dnsmasq poll for an arbitrary
181 time whilst providing service on other interfaces. Thanks
182 to Stephen Hemminger for pointing out the problem.
186 Provide a definition of the SA_SIZE macro where it's
187 missing. Fixes build failure on openBSD.
189 Don't include a zero terminator at the end of messages
190 sent to /dev/log when /dev/log is a datagram socket.
191 Thanks to Didier Rabound for spotting the problem.
193 Add --dhcp-sequential-ip flag, to force allocation of IP
194 addresses in ascending order. Note that the default
195 pseudo-random mode is in general better but some
196 server-deployment applications need this.
198 Fix problem where a server-id of 0.0.0.0 is sent to a
199 client when a dhcp-relay is in use if a client renews a
200 lease after dnsmasq restart and before any clients on the
201 subnet get a new lease. Thanks to Mike Ruiz for assistance
202 in chasing this one down.
204 Don't return NXDOMAIN to an AAAA query if we have CNAME
205 which points to an A record only: NODATA is the correct
206 reply in this case. Thanks to Tom Fernandes for spotting
209 Relax the need to supply a netmask in --dhcp-range for
210 networks which use a DHCP relay. Whilst this is still
211 desireable, in the absence of a netmask dnsmasq will use
212 a default based on the class (A, B, or C) of the address.
213 This should at least remove a cause of mysterious failure
214 for people using RFC1918 addresses and relays.
216 Add support for Linux conntrack connection marking. If
217 enabled with --conntrack, the connection mark for incoming
218 DNS queries will be copied to the outgoing connections
219 used to answer those queries. This allows clever firewall
220 and accounting stuff. Only available if dnsmasq is
221 compiled with HAVE_CONNTRACK and adds a dependency on
222 libnetfilter-conntrack. Thanks to Ed Wildgoose for the
223 initial idea, testing and sponsorship of this function.
225 Provide a sane error message when someone attempts to
226 match a tag in --dhcp-host.
228 Tweak the behaviour of --domain-needed, to avoid problems
229 with recursive nameservers downstream of dnsmasq. The new
230 behaviour only stops A and AAAA queries, and returns
231 NODATA rather than NXDOMAIN replies.
233 Efficiency fix for very large DHCP configurations, thanks
234 to James Gartrell and Mike Ruiz for help with this.
236 Allow the TFTP-server address in --dhcp-boot to be a
237 domain-name which is looked up in /etc/hosts. This can
238 give multiple IP addresses which are used round-robin,
239 thus doing TFTP server load-balancing. Thanks to Sushil
240 Agrawal for the patch.
242 When two tagged dhcp-options for a particular option
243 number are both valid, use the one which is valid without
244 a tag from the dhcp-range. Allows overriding of the value
245 of a DHCP option for a particular host as well as
246 per-network values. So
247 --dhcp-range=set:interface1,......
248 --dhcp-host=set:myhost,.....
249 --dhcp-option=tag:interface1,option:nis-domain,"domain1"
250 --dhcp-option=tag:myhost,option:nis-domain,"domain2"
251 will set the NIS-domain to domain1 for hosts in the range, but
252 override that to domain2 for a particular host.
254 Fix bug which resulted in truncated files and timeouts for
255 some TFTP transfers. The bug only occurs with netascii
256 transfers and needs an unfortunate relationship between
257 file size, blocksize and the number of newlines in the
258 last block before it manifests itself. Many thanks to
259 Alkis Georgopoulos for spotting the problem and providing
260 a comprehensive test-case.
262 Fix regression in TFTP server on *BSD platforms introduced
263 in version 2.56, due to confusion with sockaddr
264 length. Many thanks to Loïc Pefferkorn for finding this.
266 Support scope-ids in IPv6 addresses of nameservers from
267 /etc/resolv.conf and in --server options. Eg
268 nameserver fe80::202:a412:4512:7bbf%eth0 or
269 server=fe80::202:a412:4512:7bbf%eth0. Thanks to
270 Michael Stapelberg for the suggestion.
272 Update Polish translation, thanks to Jan Psota.
274 Update French translation. Thanks to Gildas Le Nadan.
278 Add patches to allow build under Android.
280 Provide our own header for the DNS protocol, rather than
281 relying on arpa/nameser.h. This has proved more or less
282 defective over the years and the final straw is that it's
283 effectively empty on Android.
285 Fix regression in 2.56 which caused hex constants in
286 configuration to be rejected if they contain the '*'
289 Correct wrong casts of arguments to ctype.h functions,
290 isdigit(), isxdigit() etc. Thanks to Matthias Andree for
293 Allow build with IDN support independently from i18n.
294 IDN support continues to be included automatically
295 when i18n is included.
296 'make COPTS=-DHAVE_IDN' is the magic incantation.
298 Modify check on extraneous command line junk (added in
299 2.56) so that it doesn't complain about extra _empty_
300 arguments. Otherwise this breaks libvirt.
304 Add a patch to allow dnsmasq to get interface names right in a
305 Solaris zone. Thanks to Dj Padzensky for this.
307 Improve data-type parsing heuristics so that
308 --dhcp-option=option:domain-search,.
309 treats the value as a string and not an IP address.
310 Thanks to Clemens Fischer for spotting that.
312 Add IPv6 support to the TFTP server. Many thanks to Jan
313 'RedBully' Seiffert for the patches.
315 Log DNS queries at level LOG_INFO, rather then
316 LOG_DEBUG. This makes things consistent with DHCP
317 logging. Thanks to Adam Pribyl for spotting the problem.
319 Ensure that dnsmasq terminates cleanly when using
320 --syslog-async even if it cannot make a connection to the
323 Add --add-mac option. This is to support currently
324 experimental DNS filtering facilities. Thanks to Benjamin
325 Petrin for the orignal patch.
327 Fix bug which meant that tags were ignored in dhcp-range
328 configuration specifying PXE-proxy service. Thanks to
329 Cristiano Cumer for spotting this.
331 Raise an error if there is extra junk, not part of an
332 option, on the command line.
334 Flag a couple of log messages in cache.c as coming from
335 the DHCP subsystem. Thanks to Olaf Westrik for the patch.
337 Omit timestamps from logs when a) logging to stderr and
338 b) --keep-in-forground is set. The logging facility on the
339 other end of stderr can be assumned to supply them. Thanks
340 to John Hallam for the patch.
342 Don't complain about strings longer than 255 characters in
343 --txt-record, just split the long strings into 255
344 character chunks instead.
346 Fix crash on double-free. This bug can only happen when
347 dhcp-script is in use and then only in rare circumstances
348 triggered by high DHCP transaction rate and a slow
349 script. Thanks to Ferenc Wagner for finding the problem.
351 Only log that a file has been sent by TFTP after the
352 transfer has completed succesfully.
354 A good suggestion from Ferenc Wagner: extend
355 the --domain option to allow this sort of thing:
356 --domain=thekelleys.org.uk,192.168.0.0/24,local
357 which automatically creates
358 --local=/thekelleys.org.uk/
359 --local=/0.168.192.in-addr.arpa/
361 Tighten up syntax checking of hex contants in the config
362 file. Thanks to Fred Damen for spotting this.
364 Add dnsmasq logo/icon, contributed by Justin Swift. Many
367 Never cache DNS replies which have the 'cd' bit set, or
368 which result from queries forwarded with the 'cd' bit
369 set. The 'cd' bit instructs a DNSSEC validating server
370 upstream to ignore signature failures and return replies
371 anyway. Without this change it's possible to pollute the
372 dnsmasq cache with bad data by making a query with the
373 'cd' bit set and subsequent queries would return this data
374 without its being marked as suspect. Thanks to Anders
375 Kaseorg for pointing out this problem.
377 Add --proxy-dnssec flag, for compliance with RFC
378 4035. Dnsmasq will now clear the 'ad' bit in answers returned
379 from upstream validating nameservers unless this option is
382 Allow a filename of "-" for --conf-file to read
383 stdin. Suggestion from Timothy Redaelli.
385 Rotate the order of SRV records in replies, to provide
386 round-robin load balancing when all the priorities are
387 equal. Thanks to Peter McKinney for the suggestion.
390 contrib/MacOSX-launchd/uk.org.thekelleys.dnsmasq.plist
391 so that it doesn't log all queries to a file by
392 default. Thanks again to Peter McKinney.
394 By default, setting an IPv4 address for a domain but not
395 an IPv6 address causes dnsmasq to return
396 an NODATA reply for IPv6 (or vice-versa). So
397 --address=/google.com/1.2.3.4 stops IPv6 queries for
398 *google.com from being forwarded. Make it possible to
399 override this behaviour by defining the sematics if the
400 same domain appears in both --server and --address.
401 In that case, the --address has priority for the address
402 family in which is appears, but the --server has priority
403 of the address family which doesn't appear in --adddress
405 --address=/google.com/1.2.3.4
406 --server=/google.com/#
407 will return 1.2.3.4 for IPv4 queries for *.google.com but
408 forward IPv6 queries to the normal upstream nameserver.
409 Similarly when setting an IPv6 address
410 only this will allow forwarding of IPv4 queries. Thanks to
411 William for pointing out the need for this.
413 Allow more than one --dhcp-optsfile and --dhcp-hostsfile
414 and make them understand directories as arguments in the
415 same way as --addn-hosts. Suggestion from John Hanks.
417 Ignore rebinding requests for leases we don't know
418 about. Rebind is broadcast, so we might get to overhear a
419 request meant for another DHCP server. NAKing this is
420 wrong. Thanks to Brad D'Hondt for assistance with this.
422 Fix cosmetic bug which produced strange output when
423 dumping cache statistics with some configurations. Thanks
424 to Fedor Kozhevnikov for spotting this.
428 Fix crash when /etc/ethers is in use. Thanks to
429 Gianluigi Tiesi for finding this.
431 Fix crash in netlink_multicast(). Thanks to Arno Wald for
434 Allow the empty domain "." in dhcp domain-search (119)
439 There is no version 2.54 to avoid confusion with 2.53,
440 which incorrectly identifies itself as 2.54.
444 Fix failure to compile on Debian/kFreeBSD. Thanks to
445 Axel Beckert and Petr Salinger.
447 Fix code to avoid scary strict-aliasing warnings
448 generated by gcc 4.4.
450 Added FAQ entry warning about DHCP failures with Vista
451 when firewalls block 255.255.255.255.
453 Fixed bug which caused bad things to happen if a
454 resolv.conf file which exists is subsequently removed.
455 Thanks to Nikolai Saoukh for the patch.
457 Rationalised the DHCP tag system. Every configuration item
458 which can set a tag does so by adding "set:<tag>" and
459 every configuration item which is conditional on a tag is
460 made so by "tag:<tag>". The NOT operator changes to '!',
461 which is a bit more intuitive too. Dhcp-host directives
462 can set more than one tag now. The old '#' NOT,
463 "net:" prefix and no-prefixes are still honoured, so
464 no existing config file needs to be changed, but
465 the documentation and new-style config files should be
468 Added --tag-if to allow boolean operations on tags.
469 This allows complicated logic to be clearer and more
470 general. A great suggestion from Richard Voigt.
472 Add broadcast/unicast information to DHCP logging.
474 Allow --dhcp-broadcast to be unconditional.
476 Fixed incorrect behaviour with NOT <tag> conditionals in
477 dhcp-options. Thanks to Max Turkewitz for assistance
480 If we send vendor-class encapsulated options based on the
481 vendor-class supplied by the client, and no explicit
482 vendor-class option is given, echo back the vendor-class
485 Fix bug which stopped dnsmasq from matching both a
486 circuitid and a remoteid. Thanks to Ignacio Bravo for
489 Add --dhcp-proxy, which makes it possible to configure
490 dnsmasq to use a DHCP relay agent as a full proxy, with
491 all DHCP messages passing through the proxy. This is
492 useful if the relay adds extra information to the packets
493 it forwards, but cannot be configured with the RFC 5107
494 server-override option.
496 Added interface:<iface name> part to dhcp-range. The
497 semantics of this are very odd at first sight, but it
498 allows a single line of the form
499 dhcp-range=interface:virt0,192.168.0.4,192.168.0.200
500 to be added to dnsmasq configuration which then supplies
501 DHCP and DNS services to that interface, without affecting
502 what services are supplied to other interfaces and
503 irrespective of the existance or lack of
504 interface=<interface>
505 lines elsewhere in the dnsmasq configuration. The idea is
506 that such a line can be added automatically by libvirt
507 or equivalent systems, without disturbing any manual
510 Similarly to the above, allow --enable-tftp=<interface>
512 Allow a TFTP root to be set separately for requests via
513 different interfaces, --tftp-root=<path>,<interface>
515 Correctly handle and log clashes between CNAMES and
516 DNS names being given to DHCP leases. This fixes a bug
517 which caused nonsense IP addresses to be logged. Thanks to
518 Sergei Zhirikov for finding and analysing the problem.
520 Tweak flush_log so as to avoid leaving the log
521 file in non-blocking mode. O_NONBLOCK is a property of the
522 file, not the process/descriptor.
524 Fix contrib/Solaris10/create_package
525 (/usr/man -> /usr/share/man) Thanks to Vita Batrla.
527 Fix a problem where, if a client got a lease, then went
528 to another subnet and got another lease, then moved back,
529 it couldn't resume the old lease, but would instead get
530 a new address. Thanks to Leonardo Rodrigues for spotting
531 this and testing the fix.
533 Fix weird bug which sometimes omitted certain characters
534 from the start of quoted strings in dhcp-options. Thanks
535 to Dayton Turner for spotting the problem.
537 Add facility to redirect some domains to the standard
538 upstream servers: this allows something like
539 --server=/google.com/1.2.3.4 --server=/www.google.com/#
540 which will send queries for *.google.com to 1.2.3.4,
541 except *www.google.com which will be forwarded as usual.
542 Thanks to AJ Weber for prompting this addition.
544 Improve the hash-algorithm used to generate IP addresses
545 from MAC addresses during initial DHCP address
546 allocation. This improves performance when large numbers
547 of hosts with similar MAC addresses all try and get an IP
548 address at the same time. Thanks to Paul Smith for his
551 Tweak DHCP code so that --bridge-interface can be used to
552 select which IP alias of an interface should be used for
553 DHCP purposes on Linux. If eth0 has an alias eth0:dhcp
554 then adding --bridge-interface=eth0:dhcp,eth0 will use
555 the address of eth0:dhcp to determine the correct subnet
556 for DHCP address allocation. Thanks to Pawel Golaszewski
557 for prompting this and Eric Cooper for further testing.
559 Add --dhcp-generate-names. Suggestion by Ferenc Wagner.
561 Tweak DNS server selection algorithm when there is more
562 than one server available for a domain, eg.
563 --server=/mydomain/1.1.1.1
564 --server=/mydomain/2.2.2.2
565 Thanks to Alberto Cuesta-Canada for spotting a weakness
568 Add --max-ttl. Thanks to Fredrik Ringertz for the patch.
570 Allow --log-facility=- to force all logging to
571 stderr. Suggestion from Clemens Fischer.
573 Fix regression which caused configuration like
574 --address=/.domain.com/1.2.3.4 to be rejected. The dot to the
575 left of the domain has been implied and not required for a
576 long time, but it should be accepted for backward
577 compatibility. Thanks to Andrew Burcin for spotting this.
579 Add --rebind-domain-ok and --rebind-localhost-ok.
580 Suggestion from Clemens Fischer.
582 Log replies to queries of type TXT, when --log-queries
585 Fix compiler warnings when compiled with -DNO_DHCP. Thanks
586 to Shantanu Gadgil for the patch.
588 Updated French translation. Thanks to Gildas Le Nadan.
590 Updated Polish translation. Thanks to Jan Psota.
592 Updated German translation. Thanks to Matthias Andree.
594 Added contrib/static-arp, thanks to Darren Hoo.
596 Fix corruption of the domain when a name from /etc/hosts
597 overrides one supplied by a DHCP client. Thanks to Fedor
598 Kozhevnikov for spotting the problem.
600 Updated Spanish translation. Thanks to Chris Chatham.
604 Work around a Linux kernel bug which insists that the
605 length of the option passed to setsockopt must be at least
606 sizeof(int) bytes, even if we're calling SO_BINDTODEVICE
607 and the device name is "lo". Note that this is fixed
608 in kernel 2.6.31, but the workaround is harmless and
609 allows earlier kernels to be used. Also fix dnsmasq
610 bug which reported the wrong address when this failed.
611 Thanks to Fedor for finding this.
613 The API for IPv6 PKTINFO changed around Linux kernel
614 2.6.14. Workaround the case where dnsmasq is compiled
615 against newer headers, but then run on an old kernel:
616 necessary for some *WRT distros.
618 Re-read the set of network interfaces when re-loading
619 /etc/resolv.conf if --bind-interfaces is not set. This
620 handles the case that loopback interfaces do not exist
621 when dnsmasq is first started.
623 Tweak the PXE code to support port 4011. This should
624 reduce broadcasts and make things more reliable when other
625 servers are around. It also improves inter-operability
626 with certain clients.
628 Make a pxe-service configuration with no filename or boot
629 service type legal: this does a local boot. eg.
630 pxe-service=x86PC, "Local boot"
632 Be more conservative in detecting "A for A"
633 queries. Dnsmasq checks if the name in a type=A query looks
634 like a dotted-quad IP address and answers the query itself
635 if so, rather than forwarding it. Previously dnsmasq
636 relied in the library function inet_addr() to convert
637 addresses, and that will accept some things which are
638 confusing in this context, like 1.2.3 or even just
639 1234. Now we only do A for A processing for four decimal
640 numbers delimited by dots.
642 A couple of tweaks to fix compilation on Solaris. Thanks
643 to Joel Macklow for help with this.
645 Another Solaris compilation tweak, needed for Solaris
646 2009.06. Thanks to Lee Essen for that.
648 Added extract packaging stuff from Lee Essen to
651 Increased the default limit on number of leases to 1000
652 (from 150). This is mainly a defence against DoS attacks,
653 and for the average "one for two class C networks"
654 installation, IP address exhaustion does that just as
655 well. Making the limit greater than the number of IP
656 addresses available in such an installation removes a
657 surprise which otherwise can catch people out.
659 Removed extraneous trailing space in the value of the
660 DNSMASQ_TIME_REMAINING DNSMASQ_LEASE_LENGTH and
661 DNSMASQ_LEASE_EXPIRES environment variables. Thanks to
662 Gildas Le Nadan for spotting this.
664 Provide the network-id tags for a DHCP transaction to
665 the lease-change script in the environment variable
666 DNSMASQ_TAGS. A good suggestion from Gildas Le Nadan.
668 Add support for RFC3925 "Vendor-Identifying Vendor
669 Options". The syntax looks like this:
670 --dhcp-option=vi-encap:<enterprise number>, .........
672 Add support to --dhcp-match to allow matching against
673 RFC3925 "Vendor-Identifying Vendor Classes". The syntax
675 --dhcp-match=tag,vi-encap<enterprise number>, <value>
677 Add some application specific code to assist in
678 implementing the Broadband forum TR069 CPE-WAN
679 specification. The details are in contrib/CPE-WAN/README
681 Increase the default DNS packet size limit to 4096, as
682 recommended by RFC5625 section 4.4.3. This can be
683 reconfigured using --edns-packet-max if needed. Thanks to
684 Francis Dupont for pointing this out.
686 Rewrite query-ids even for TSIG signed packets, since
687 this is allowed by RFC5625 section 4.5.
689 Use getopt_long by default on OS X. It has been supported
690 since version 10.3.0. Thanks to Arek Dreyer for spotting
693 Added up-to-date startup configuration for MacOSX/launchd
694 in contrib/MacOSX-launchd. Thanks to Arek Dreyer for
697 Fix link error when including Dbus but excluding DHCP.
698 Thanks to Oschtan for the bug report.
700 Updated French translation. Thanks to Gildas Le Nadan.
702 Updated Polish translation. Thanks to Jan Psota.
704 Updated Spanish translation. Thanks to Chris Chatham.
706 Fixed confusion about domains, when looking up DHCP hosts
707 in /etc/hosts. This could cause spurious "Ignoring
708 domain..." messages. Thanks to Fedor Kozhevnikov for
709 finding and analysing the problem.
713 Add support for internationalised DNS. Non-ASCII characters
714 in domain names found in /etc/hosts, /etc/ethers and
715 /etc/dnsmasq.conf will be correctly handled by translation to
716 punycode, as specified in RFC3490. This function is only
717 available if dnsmasq is compiled with internationalisation
718 support, and adds a dependency on GNU libidn. Without i18n
719 support, dnsmasq continues to be compilable with just
720 standard tools. Thanks to Yves Dorfsman for the
723 Add two more environment variables for lease-change scripts:
724 First, DNSMASQ_SUPPLIED_HOSTNAME; this is set to the hostname
725 supplied by a client, even if the actual hostname used is
726 over-ridden by dhcp-host or dhcp-ignore-names directives.
727 Also DNSMASQ_RELAY_ADDRESS which gives the address of
728 a DHCP relay, if used.
729 Suggestions from Michael Rack.
731 Fix regression which broke echo of relay-agent
732 options. Thanks to Michael Rack for spotting this.
734 Don't treat option 67 as being interchangeable with
735 dhcp-boot parameters if it's specified as
738 Make the code to call scripts on lease-change compile-time
739 optional. It can be switched off by editing src/config.h
740 or building with "make COPTS=-DNO_SCRIPT".
742 Make the TFTP server cope with filenames from Windows/DOS
743 which use '\' as pathname separator. Thanks to Ralf for
746 Updated Polish translation. Thanks to Jan Psota.
748 Warn if an IP address is duplicated in /etc/ethers. Thanks
749 to Felix Schwarz for pointing this out.
751 Teach --conf-dir to take an option list of file suffices
752 which will be ignored when scanning the directory. Useful
753 for backup files etc. Thanks to Helmut Hullen for the
756 Add new DHCP option named tftpserver-address, which
757 corresponds to the third argument of dhcp-boot. This
758 allows the complete functionality of dhcp-boot to be
759 replicated with dhcp-option. Useful when using
762 Test which upstream nameserver to use every 10 seconds
763 or 50 queries and not just when a query times out and
764 is retried. This should improve performance when there
765 is a slow nameserver in the list. Thanks to Joe for the
768 Don't do any PXE processing, even for clients with the
769 correct vendorclass, unless at least one pxe-prompt or
770 pxe-service option is given. This stops dnsmasq
771 interfering with proxy PXE subsystems when it is just
772 the DHCP server. Thanks to Spencer Clark for spotting this.
774 Limit the blocksize used for TFTP transfers to a value
775 which avoids packet fragmentation, based on the MTU of the
776 local interface. Many netboot ROMs can't cope with
779 Honour dhcp-ignore configuration for PXE and proxy-PXE
780 requests. Thanks to Niels Basjes for the bug report.
782 Updated French translation. Thanks to Gildas Le Nadan.
786 Fix security problem which allowed any host permitted to
787 do TFTP to possibly compromise dnsmasq by remote buffer
788 overflow when TFTP enabled. Thanks to Core Security
789 Technologies and Iván Arce, Pablo Hernán Jorge, Alejandro
790 Pablo Rodriguez, Martín Coco, Alberto Soliño Testa and
791 Pablo Annetta. This problem has Bugtraq id: 36121
794 Fix a problem which allowed a malicious TFTP client to
795 crash dnsmasq. Thanks to Steve Grubb at Red Hat for
796 spotting this. This problem has Bugtraq id: 36120 and
801 Fix regression in 2.48 which disables the lease-change
802 script. Thanks to Jose Luis Duran for spotting this.
804 Log TFTP "file not found" errors. These were not logged,
805 since a normal PXELinux boot generates many of them, but
806 the lack of the messages seems to be more confusing than
807 routinely seeing them when there is no real error.
809 Update Spanish translation. Thanks to Chris Chatham.
813 Archived the extensive, backwards, changelog to
814 CHANGELOG.archive. The current changelog now runs from
815 version 2.43 and runs conventionally.
817 Fixed bug which broke binding of servers to physical
818 interfaces when interface names were longer than four
819 characters. Thanks to MURASE Katsunori for the patch.
821 Fixed netlink code to check that messages come from the
822 correct source, and not another userspace process. Thanks
823 to Steve Grubb for the patch.
825 Maintainability drive: removed bug and missing feature
826 workarounds for some old platforms. Solaris 9, OpenBSD
827 older than 4.1, Glibc older than 2.2, Linux 2.2.x and
828 DBus older than 1.1.x are no longer supported.
830 Don't read included configuration files more than once:
831 allows complex configuration structures without problems.
833 Mark log messages from the various subsystems in dnsmasq:
834 messages from the DHCP subsystem now have the ident string
835 "dnsmasq-dhcp" and messages from TFTP have ident
836 "dnsmasq-tftp". Thanks to Olaf Westrik for the patch.
838 Fix possible infinite DHCP protocol loop when an IP
839 address nailed to a hostname (not a MAC address) and a
840 host sometimes provides the name, sometimes not.
842 Allow --addn-hosts to take a directory: all the files
843 in the directory are read. Thanks to Phil Cornelius for
846 Support --bridge-interface on all platforms, not just BSD.
848 Added support for advanced PXE functions. It's now
849 possible to define a prompt and menu options which will
850 be displayed when a client PXE boots. It's also possible to
851 hand-off booting to other boot servers. Proxy-DHCP, where
852 dnsmasq just supplies the PXE information and another DHCP
853 server does address allocation, is also allowed. See the
854 --pxe-prompt and --pxe-service keywords. Thanks to
855 Alkis Georgopoulos for the suggestion and Guilherme Moro
856 and Michael Brown for assistance.
858 Improvements to DHCP logging. Thanks to Tom Metro for
861 Add ability to build dnsmasq without DHCP support. To do
862 this, edit src/config.h or build with
863 "make COPTS=-DNO_DHCP". Thanks to Mahavir Jain for the patch.
865 Added --test command-line switch - syntax check
866 configuration files only.
868 Updated French translation. Thanks to Gildas Le Nadan.
872 Updated French translation. Thanks to Gildas Le Nadan.
874 Fixed interface enumeration code to work on NetBSD
875 5.0. Thanks to Roy Marples for the patch.
877 Updated config.h to use the same location for the lease
878 file on NetBSD as the other *BSD variants. Also allow
879 LEASEFILE and CONFFILE symbols to be overriden in CFLAGS.
881 Handle duplicate address detection on IPv6 more
882 intelligently. In IPv6, an interface can have an address
883 which is not usable, because it is still undergoing DAD
884 (such addresses are marked "tentative"). Attempting to
885 bind to an address in this state returns an error,
886 EADDRNOTAVAIL. Previously, on getting such an error,
887 dnsmasq would silently abandon the address, and never
888 listen on it. Now, it retries once per second for 20
889 seconds before generating a fatal error. 20 seconds should
890 be long enough for any DAD process to complete, but can be
891 adjusted in src/config.h if necessary. Thanks to Martin
892 Krafft for the bug report.
894 Add DBus introspection. Patch from Jeremy Laine.
896 Update Dbus configuration file. Patch from Colin Walters.
898 http://bugs.freedesktop.org/show_bug.cgi?id=18961
900 Support arbitrarily encapsulated DHCP options, suggestion
901 and initial patch from Samium Gromoff. This is useful for
902 (eg) gPXE, which expect all its private options to be
903 encapsulated inside a single option 175. So, eg,
905 dhcp-option = encap:175, 190, "iscsi-client0"
906 dhcp-option = encap:175, 191, "iscsi-client0-secret"
908 will provide iSCSI parameters to gPXE.
910 Enhance --dhcp-match to allow testing of the contents of a
911 client-sent option, as well as its presence. This
912 application in mind for this is RFC 4578
913 client-architecture specifiers, but it's generally useful.
914 Joey Korkames suggested the enhancement.
916 Move from using the IP_XMIT_IF ioctl to IP_BOUND_IF on
917 OpenSolaris. Thanks to Bastian Machek for the heads-up.
919 No longer complain about blank lines in
920 /etc/ethers. Thanks to Jon Nelson for the patch.
922 Fix binding of servers to physical devices, eg
923 --server=/domain/1.2.3.4@eth0 which was broken from 2.43
924 onwards unless --query-port=0 set. Thanks to Peter Naulls
927 Reply to DHCPINFORM requests even when the supplied ciaddr
928 doesn't fall in any dhcp-range. In this case it's not
929 possible to supply a complete configuration, but
930 individually-configured options (eg PAC) may be useful.
932 Allow the source address of an alias to be a range:
933 --alias=192.168.0.0,10.0.0.0,255.255.255.0 maps the whole
934 subnet 192.168.0.0->192.168.0.255 to 10.0.0.0->10.0.0.255,
936 --alias=192.168.0.10-192.168.0.40,10.0.0.0,255.255.255.0
937 maps only the 192.168.0.10->192.168.0.40 region. Thanks to
938 Ib Uhrskov for the suggestion.
940 Don't dynamically allocate DHCP addresses which may break
941 Windows. Addresses which end in .255 or .0 are broken in
942 Windows even when using supernetting.
943 --dhcp-range=192.168.0.1,192.168.1.254,255,255,254.0 means
944 192.168.0.255 is a valid IP address, but not for Windows.
945 See Microsoft KB281579. We therefore no longer allocate
946 these addresses to avoid hard-to-diagnose problems.
948 Update Polish translation. Thanks to Jan Psota.
950 Delete the PID-file when dnsmasq shuts down. Note that by
951 this time, dnsmasq is normally not running as root, so
952 this will fail if the PID-file is stored in a root-owned
953 directory; such failure is silently ignored. To take
954 advantage of this feature, the PID-file must be stored in a
955 directory owned and write-able by the user running
960 Allow --bootp-dynamic to take a netid tag, so that it may
961 be selectively enabled. Thanks to Olaf Westrik for the
964 Remove ISC-leasefile reading code. This has been
965 deprecated for a long time, and last time I removed it, it
966 ended up going back by request of one user. This time,
967 it's gone for good; otherwise it would need to be
968 re-worked to support multiple domains (see below).
970 Support DHCP clients in multiple DNS domains. This is a
971 long-standing request. Clients are assigned to a domain
972 based in their IP address.
974 Add --dhcp-fqdn flag, which changes behaviour if DNS names
975 assigned to DHCP clients. When this is set, there must be
976 a domain associated with each client, and only
977 fully-qualified domain names are added to the DNS. The
978 advantage is that the only the FQDN needs to be unique,
979 so that two or more DHCP clients can share a hostname, as
980 long as they are in different domains.
982 Set environment variable DNSMASQ_DOMAIN when invoking
983 lease-change script. This may be useful information to
984 have now that it's variable.
986 Tighten up data-checking code for DNS packet
987 handling. Thanks to Steve Dodd who found certain illegal
988 packets which could crash dnsmasq. No memory overwrite was
989 possible, so this is not a security issue beyond the DoS
992 Update example config dhcp option 47, the previous
993 suggestion generated an illegal, zero-length,
994 option. Thanks to Matthias Andree for finding this.
996 Rewrite hosts-file reading code to remove the limit of
997 1024 characters per line. John C Meuser found this.
999 Create a net-id tag with the name of the interface on
1000 which the DHCP request was received.
1002 Fixed minor memory leak in DBus code, thanks to Jeremy
1003 Laine for the patch.
1005 Emit DBus signals as the DHCP lease database
1006 changes. Thanks to Jeremy Laine for the patch.
1008 Allow for more that one MAC address in a dhcp-host
1009 line. This configuration tells dnsmasq that it's OK to
1010 abandon a DHCP lease of the fixed address to one MAC
1011 address, if another MAC address in the dhcp-host statement
1012 asks for an address. This is useful to give a fixed
1013 address to a host which has two network interfaces
1014 (say, a laptop with wired and wireless interfaces.)
1015 It's very important to ensure that only one interface
1016 at a time is up, since dnsmasq abandons the first lease
1017 and re-uses the address before the leased time has
1018 elapsed. John Gray suggested this.
1020 Tweak the response to a DHCP request packet with a wrong
1021 server-id when --dhcp-authoritative is set; dnsmasq now
1022 returns a DHCPNAK, rather than silently ignoring the
1023 packet. Thanks to Chris Marget for spotting this
1026 Add --cname option. This provides a limited alias
1027 function, usable for DHCP names. Thanks to AJ Weber for
1028 suggestions on this.
1030 Updated contrib/webmin with latest version from Neil
1033 Updated Polish translation. Thanks to Jan Psota.
1035 Correct the text names for DHCP options 64 and 65 to be
1036 "nis+-domain" and "nis+-servers".
1038 Updated Spanish translation. Thanks to Chris Chatham.
1040 Force re-reading of /etc/resolv.conf when an "interface
1045 Fix total DNS failure in release 2.44 unless --min-port
1046 specified. Thanks to Steven Barth and Grant Coady for
1047 bugreport. Also reject out-of-range port spec, which could
1048 break things too: suggestion from Gilles Espinasse.
1052 Fix crash when unknown client attempts to renew a DHCP
1053 lease, problem introduced in version 2.43. Thanks to
1054 Carlos Carvalho for help chasing this down.
1056 Fix potential crash when a host which doesn't have a lease
1057 does DHCPINFORM. Again introduced in 2.43. This bug has
1058 never been reported in the wild.
1060 Fix crash in netlink code introduced in 2.43. Thanks to
1061 Jean Wolter for finding this.
1063 Change implementation of min_port to work even if min-port
1066 Patch to enable compilation of latest Mac OS X. Thanks to
1069 Update Spanish translation. Thanks to Christopher Chatham.
1073 Updated Polish translation. Thanks to Jan Psota.
1075 Flag errors when configuration options are repeated
1078 Further tweaks for GNU/kFreeBSD
1080 Add --no-wrap to msgmerge call - provides nicer .po file
1083 Honour lease-time spec in dhcp-host lines even for
1084 BOOTP. The user is assumed to known what they are doing in
1085 this case. (Hosts without the time spec still get infinite
1086 leases for BOOTP, over-riding the default in the
1087 dhcp-range.) Thanks to Peter Katzmann for uncovering this.
1089 Fix problem matching relay-agent ids. Thanks to Michael
1090 Rack for the bug report.
1092 Add --naptr-record option. Suggestion from Johan
1095 Implement RFC 5107 server-id-override DHCP relay agent
1098 Apply patches from Stefan Kruger for compilation on
1099 Solaris 10 under Sun studio.
1101 Yet more tweaking of Linux capability code, to suppress
1102 pointless wingeing from kernel 2.6.25 and above.
1104 Improve error checking during startup. Previously, some
1105 errors which occurred during startup would be worked
1106 around, with dnsmasq still starting up. Some were logged,
1107 some silent. Now, they all cause a fatal error and dnsmasq
1108 terminates with a non-zero exit code. The errors are those
1109 associated with changing uid and gid, setting process
1110 capabilities and writing the pidfile. Thanks to Uwe
1111 Gansert and the Suse security team for pointing out
1112 this improvement, and Bill Reimers for good implementation
1115 Provide NO_LARGEFILE compile option to switch off largefile
1116 support when compiling against versions of uclibc which
1117 don't support it. Thanks to Stephane Billiart for the patch.
1119 Implement random source ports for interactions with
1120 upstream nameservers. New spoofing attacks have been found
1121 against nameservers which do not do this, though it is not
1122 clear if dnsmasq is vulnerable, since to doesn't implement
1123 recursion. By default dnsmasq will now use a different
1124 source port (and socket) for each query it sends
1125 upstream. This behaviour can suppressed using the
1126 --query-port option, and the old default behaviour
1127 restored using --query-port=0. Explicit source-port
1128 specifications in --server configs are still honoured.
1130 Replace the random number generator, for better
1131 security. On most BSD systems, dnsmasq uses the
1132 arc4random() RNG, which is secure, but on other platforms,
1133 it relied on the C-library RNG, which may be
1134 guessable and therefore allow spoofing. This release
1135 replaces the libc RNG with the SURF RNG, from Daniel
1136 J. Berstein's DJBDNS package.
1138 Don't attempt to change user or group or set capabilities
1139 if dnsmasq is run as a non-root user. Without this, the
1140 change from soft to hard errors when these fail causes
1141 problems for non-root daemons listening on high
1142 ports. Thanks to Patrick McLean for spotting this.
1144 Updated French translation. Thanks to Gildas Le Nadan.
1148 The changelog for version 2.42 and earlier is
1149 available in CHANGELOG.archive.
