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 DHCPv6 keyword which adds AAAA records
8 for dual-stack hosts which get IPv6 addresses via SLAAC.
12 Fix compilation problem in Mac OS X Lion. Thanks to Olaf
15 Fix DHCP when using --listen-address with an IP address
16 which is not the primary address of an interface.
18 Add --dhcp-client-update option.
20 Add Lua integration. Dnsmasq can now execute a DHCP
21 lease-change script written in Lua. This needs to be
22 enabled at compile time by setting HAVE_LUASCRIPT in
23 src/config.h or running "make COPTS=-DHAVE_LUASCRIPT"
24 Thanks to Jan-Piet Mens for the idea and proof-of-concept
27 Tidied src/config.h to distinguish between
28 platform-dependent compile-time options which are selected
29 automatically, and builder-selectable compile time
30 options. Document the latter better, and describe how to
31 set them from the make command line.
33 Tidied up IPPROTO_IP/SOL_IP (and IPv6 equivalent)
34 confusion. IPPROTO_IP works everywhere now.
36 Set TOS on DHCP sockets, this improves things on busy
37 wireless networks. Thanks to Dave Taht for the patch.
39 Determine VERSION automatically based on git magic:
40 release tags or hash values.
42 Improve start-up speed when reading large hosts files
43 containing many distinct addresses.
45 Fix problem if dnsmasq is started without the stdin,
46 stdout and stderr file descriptors open. This can manifest
47 itself as 100% CPU use. Thanks to Chris Moore for finding
50 Fix shell-scripting bug in bld/pkg-wrapper. Thanks to
51 Mark Mitchell for the patch.
53 Allow the TFP server or boot server in --pxe-service, to
54 be a domain name instead of an IP address. This allows for
55 round-robin to multiple servers, in the same way as
56 --dhcp-boot. A good suggestion from Cristiano Cumer.
58 Support BUILDDIR variable in the Makefile. Allows builds
59 for multiple archs from the same source tree with eg.
60 make BUILDDIR=linux (relative to dnsmasq tree)
61 make BUILDDIR=/tmp/openbsd (absolute path)
62 If BUILDDIR is not set, compilation happens in the src
63 directory, as before. Suggestion from Mark Mitchell.
65 Support DHCPv6. Support is there for the sort of things
66 the existing v4 server does, including tags, options,
67 static addresses and relay support. Missing is prefix
68 delegation, which is probably not required in the dnsmasq
69 niche, and an easy way to accept prefix delegations from
70 an upstream DHCPv6 server, which is. Future plans include
71 support for DHCPv6 router option and MAC address option
72 (to make selecting clients by MAC address work like IPv4).
73 These will be added as the standards mature.
74 This code has been tested, but this is the first release,
75 so don't bet the farm on it just yet. Many thanks to all
76 testers who have got it this far.
78 Support IPv6 router advertisements. This is a
79 simple-minded implementation, aimed at providing the
80 vestigial RA needed to go alongside IPv6. Is picks up
81 configuration from the DHCPv6 conf, and should just need
82 enabling with --enable-ra.
84 Fix long-standing wrinkle with --localise-queries that
85 could result in wrong answers when DNS packets arrive
86 via an interface other than the expected one. Thanks to
87 Lorenzo Milesi and John Hanks for spotting this one.
89 Update French translation. Thanks to Gildas Le Nadan.
91 Update Polish translation. Thanks to Jan Psota.
95 Fix regression in 2.58 which caused failure to start up
96 with some combinations of dnsmasq config and IPv6 kernel
97 network config. Thanks to Brielle Bruns for the bug
100 Improve dnsmasq's behaviour when network interfaces are
101 still doing duplicate address detection (DAD). Previously,
102 dnsmasq would wait up to 20 seconds at start-up for the
103 DAD state to terminate. This is broken for bridge
104 interfaces on recent Linux kernels, which don't start DAD
105 until the bridge comes up, and so can take arbitrary
106 time. The new behaviour lets dnsmasq poll for an arbitrary
107 time whilst providing service on other interfaces. Thanks
108 to Stephen Hemminger for pointing out the problem.
112 Provide a definition of the SA_SIZE macro where it's
113 missing. Fixes build failure on openBSD.
115 Don't include a zero terminator at the end of messages
116 sent to /dev/log when /dev/log is a datagram socket.
117 Thanks to Didier Rabound for spotting the problem.
119 Add --dhcp-sequential-ip flag, to force allocation of IP
120 addresses in ascending order. Note that the default
121 pseudo-random mode is in general better but some
122 server-deployment applications need this.
124 Fix problem where a server-id of 0.0.0.0 is sent to a
125 client when a dhcp-relay is in use if a client renews a
126 lease after dnsmasq restart and before any clients on the
127 subnet get a new lease. Thanks to Mike Ruiz for assistance
128 in chasing this one down.
130 Don't return NXDOMAIN to an AAAA query if we have CNAME
131 which points to an A record only: NODATA is the correct
132 reply in this case. Thanks to Tom Fernandes for spotting
135 Relax the need to supply a netmask in --dhcp-range for
136 networks which use a DHCP relay. Whilst this is still
137 desireable, in the absence of a netmask dnsmasq will use
138 a default based on the class (A, B, or C) of the address.
139 This should at least remove a cause of mysterious failure
140 for people using RFC1918 addresses and relays.
142 Add support for Linux conntrack connection marking. If
143 enabled with --conntrack, the connection mark for incoming
144 DNS queries will be copied to the outgoing connections
145 used to answer those queries. This allows clever firewall
146 and accounting stuff. Only available if dnsmasq is
147 compiled with HAVE_CONNTRACK and adds a dependency on
148 libnetfilter-conntrack. Thanks to Ed Wildgoose for the
149 initial idea, testing and sponsorship of this function.
151 Provide a sane error message when someone attempts to
152 match a tag in --dhcp-host.
154 Tweak the behaviour of --domain-needed, to avoid problems
155 with recursive nameservers downstream of dnsmasq. The new
156 behaviour only stops A and AAAA queries, and returns
157 NODATA rather than NXDOMAIN replies.
159 Efficiency fix for very large DHCP configurations, thanks
160 to James Gartrell and Mike Ruiz for help with this.
162 Allow the TFTP-server address in --dhcp-boot to be a
163 domain-name which is looked up in /etc/hosts. This can
164 give multiple IP addresses which are used round-robin,
165 thus doing TFTP server load-balancing. Thanks to Sushil
166 Agrawal for the patch.
168 When two tagged dhcp-options for a particular option
169 number are both valid, use the one which is valid without
170 a tag from the dhcp-range. Allows overriding of the value
171 of a DHCP option for a particular host as well as
172 per-network values. So
173 --dhcp-range=set:interface1,......
174 --dhcp-host=set:myhost,.....
175 --dhcp-option=tag:interface1,option:nis-domain,"domain1"
176 --dhcp-option=tag:myhost,option:nis-domain,"domain2"
177 will set the NIS-domain to domain1 for hosts in the range, but
178 override that to domain2 for a particular host.
180 Fix bug which resulted in truncated files and timeouts for
181 some TFTP transfers. The bug only occurs with netascii
182 transfers and needs an unfortunate relationship between
183 file size, blocksize and the number of newlines in the
184 last block before it manifests itself. Many thanks to
185 Alkis Georgopoulos for spotting the problem and providing
186 a comprehensive test-case.
188 Fix regression in TFTP server on *BSD platforms introduced
189 in version 2.56, due to confusion with sockaddr
190 length. Many thanks to Loïc Pefferkorn for finding this.
192 Support scope-ids in IPv6 addresses of nameservers from
193 /etc/resolv.conf and in --server options. Eg
194 nameserver fe80::202:a412:4512:7bbf%eth0 or
195 server=fe80::202:a412:4512:7bbf%eth0. Thanks to
196 Michael Stapelberg for the suggestion.
198 Update Polish translation, thanks to Jan Psota.
200 Update French translation. Thanks to Gildas Le Nadan.
204 Add patches to allow build under Android.
206 Provide our own header for the DNS protocol, rather than
207 relying on arpa/nameser.h. This has proved more or less
208 defective over the years and the final straw is that it's
209 effectively empty on Android.
211 Fix regression in 2.56 which caused hex constants in
212 configuration to be rejected if they contain the '*'
215 Correct wrong casts of arguments to ctype.h functions,
216 isdigit(), isxdigit() etc. Thanks to Matthias Andree for
219 Allow build with IDN support independently from i18n.
220 IDN support continues to be included automatically
221 when i18n is included.
222 'make COPTS=-DHAVE_IDN' is the magic incantation.
224 Modify check on extraneous command line junk (added in
225 2.56) so that it doesn't complain about extra _empty_
226 arguments. Otherwise this breaks libvirt.
230 Add a patch to allow dnsmasq to get interface names right in a
231 Solaris zone. Thanks to Dj Padzensky for this.
233 Improve data-type parsing heuristics so that
234 --dhcp-option=option:domain-search,.
235 treats the value as a string and not an IP address.
236 Thanks to Clemens Fischer for spotting that.
238 Add IPv6 support to the TFTP server. Many thanks to Jan
239 'RedBully' Seiffert for the patches.
241 Log DNS queries at level LOG_INFO, rather then
242 LOG_DEBUG. This makes things consistent with DHCP
243 logging. Thanks to Adam Pribyl for spotting the problem.
245 Ensure that dnsmasq terminates cleanly when using
246 --syslog-async even if it cannot make a connection to the
249 Add --add-mac option. This is to support currently
250 experimental DNS filtering facilities. Thanks to Benjamin
251 Petrin for the orignal patch.
253 Fix bug which meant that tags were ignored in dhcp-range
254 configuration specifying PXE-proxy service. Thanks to
255 Cristiano Cumer for spotting this.
257 Raise an error if there is extra junk, not part of an
258 option, on the command line.
260 Flag a couple of log messages in cache.c as coming from
261 the DHCP subsystem. Thanks to Olaf Westrik for the patch.
263 Omit timestamps from logs when a) logging to stderr and
264 b) --keep-in-forground is set. The logging facility on the
265 other end of stderr can be assumned to supply them. Thanks
266 to John Hallam for the patch.
268 Don't complain about strings longer than 255 characters in
269 --txt-record, just split the long strings into 255
270 character chunks instead.
272 Fix crash on double-free. This bug can only happen when
273 dhcp-script is in use and then only in rare circumstances
274 triggered by high DHCP transaction rate and a slow
275 script. Thanks to Ferenc Wagner for finding the problem.
277 Only log that a file has been sent by TFTP after the
278 transfer has completed succesfully.
280 A good suggestion from Ferenc Wagner: extend
281 the --domain option to allow this sort of thing:
282 --domain=thekelleys.org.uk,192.168.0.0/24,local
283 which automatically creates
284 --local=/thekelleys.org.uk/
285 --local=/0.168.192.in-addr.arpa/
287 Tighten up syntax checking of hex contants in the config
288 file. Thanks to Fred Damen for spotting this.
290 Add dnsmasq logo/icon, contributed by Justin Swift. Many
293 Never cache DNS replies which have the 'cd' bit set, or
294 which result from queries forwarded with the 'cd' bit
295 set. The 'cd' bit instructs a DNSSEC validating server
296 upstream to ignore signature failures and return replies
297 anyway. Without this change it's possible to pollute the
298 dnsmasq cache with bad data by making a query with the
299 'cd' bit set and subsequent queries would return this data
300 without its being marked as suspect. Thanks to Anders
301 Kaseorg for pointing out this problem.
303 Add --proxy-dnssec flag, for compliance with RFC
304 4035. Dnsmasq will now clear the 'ad' bit in answers returned
305 from upstream validating nameservers unless this option is
308 Allow a filename of "-" for --conf-file to read
309 stdin. Suggestion from Timothy Redaelli.
311 Rotate the order of SRV records in replies, to provide
312 round-robin load balancing when all the priorities are
313 equal. Thanks to Peter McKinney for the suggestion.
316 contrib/MacOSX-launchd/uk.org.thekelleys.dnsmasq.plist
317 so that it doesn't log all queries to a file by
318 default. Thanks again to Peter McKinney.
320 By default, setting an IPv4 address for a domain but not
321 an IPv6 address causes dnsmasq to return
322 an NODATA reply for IPv6 (or vice-versa). So
323 --address=/google.com/1.2.3.4 stops IPv6 queries for
324 *google.com from being forwarded. Make it possible to
325 override this behaviour by defining the sematics if the
326 same domain appears in both --server and --address.
327 In that case, the --address has priority for the address
328 family in which is appears, but the --server has priority
329 of the address family which doesn't appear in --adddress
331 --address=/google.com/1.2.3.4
332 --server=/google.com/#
333 will return 1.2.3.4 for IPv4 queries for *.google.com but
334 forward IPv6 queries to the normal upstream nameserver.
335 Similarly when setting an IPv6 address
336 only this will allow forwarding of IPv4 queries. Thanks to
337 William for pointing out the need for this.
339 Allow more than one --dhcp-optsfile and --dhcp-hostsfile
340 and make them understand directories as arguments in the
341 same way as --addn-hosts. Suggestion from John Hanks.
343 Ignore rebinding requests for leases we don't know
344 about. Rebind is broadcast, so we might get to overhear a
345 request meant for another DHCP server. NAKing this is
346 wrong. Thanks to Brad D'Hondt for assistance with this.
348 Fix cosmetic bug which produced strange output when
349 dumping cache statistics with some configurations. Thanks
350 to Fedor Kozhevnikov for spotting this.
354 Fix crash when /etc/ethers is in use. Thanks to
355 Gianluigi Tiesi for finding this.
357 Fix crash in netlink_multicast(). Thanks to Arno Wald for
360 Allow the empty domain "." in dhcp domain-search (119)
365 There is no version 2.54 to avoid confusion with 2.53,
366 which incorrectly identifies itself as 2.54.
370 Fix failure to compile on Debian/kFreeBSD. Thanks to
371 Axel Beckert and Petr Salinger.
373 Fix code to avoid scary strict-aliasing warnings
374 generated by gcc 4.4.
376 Added FAQ entry warning about DHCP failures with Vista
377 when firewalls block 255.255.255.255.
379 Fixed bug which caused bad things to happen if a
380 resolv.conf file which exists is subsequently removed.
381 Thanks to Nikolai Saoukh for the patch.
383 Rationalised the DHCP tag system. Every configuration item
384 which can set a tag does so by adding "set:<tag>" and
385 every configuration item which is conditional on a tag is
386 made so by "tag:<tag>". The NOT operator changes to '!',
387 which is a bit more intuitive too. Dhcp-host directives
388 can set more than one tag now. The old '#' NOT,
389 "net:" prefix and no-prefixes are still honoured, so
390 no existing config file needs to be changed, but
391 the documentation and new-style config files should be
394 Added --tag-if to allow boolean operations on tags.
395 This allows complicated logic to be clearer and more
396 general. A great suggestion from Richard Voigt.
398 Add broadcast/unicast information to DHCP logging.
400 Allow --dhcp-broadcast to be unconditional.
402 Fixed incorrect behaviour with NOT <tag> conditionals in
403 dhcp-options. Thanks to Max Turkewitz for assistance
406 If we send vendor-class encapsulated options based on the
407 vendor-class supplied by the client, and no explicit
408 vendor-class option is given, echo back the vendor-class
411 Fix bug which stopped dnsmasq from matching both a
412 circuitid and a remoteid. Thanks to Ignacio Bravo for
415 Add --dhcp-proxy, which makes it possible to configure
416 dnsmasq to use a DHCP relay agent as a full proxy, with
417 all DHCP messages passing through the proxy. This is
418 useful if the relay adds extra information to the packets
419 it forwards, but cannot be configured with the RFC 5107
420 server-override option.
422 Added interface:<iface name> part to dhcp-range. The
423 semantics of this are very odd at first sight, but it
424 allows a single line of the form
425 dhcp-range=interface:virt0,192.168.0.4,192.168.0.200
426 to be added to dnsmasq configuration which then supplies
427 DHCP and DNS services to that interface, without affecting
428 what services are supplied to other interfaces and
429 irrespective of the existance or lack of
430 interface=<interface>
431 lines elsewhere in the dnsmasq configuration. The idea is
432 that such a line can be added automatically by libvirt
433 or equivalent systems, without disturbing any manual
436 Similarly to the above, allow --enable-tftp=<interface>
438 Allow a TFTP root to be set separately for requests via
439 different interfaces, --tftp-root=<path>,<interface>
441 Correctly handle and log clashes between CNAMES and
442 DNS names being given to DHCP leases. This fixes a bug
443 which caused nonsense IP addresses to be logged. Thanks to
444 Sergei Zhirikov for finding and analysing the problem.
446 Tweak flush_log so as to avoid leaving the log
447 file in non-blocking mode. O_NONBLOCK is a property of the
448 file, not the process/descriptor.
450 Fix contrib/Solaris10/create_package
451 (/usr/man -> /usr/share/man) Thanks to Vita Batrla.
453 Fix a problem where, if a client got a lease, then went
454 to another subnet and got another lease, then moved back,
455 it couldn't resume the old lease, but would instead get
456 a new address. Thanks to Leonardo Rodrigues for spotting
457 this and testing the fix.
459 Fix weird bug which sometimes omitted certain characters
460 from the start of quoted strings in dhcp-options. Thanks
461 to Dayton Turner for spotting the problem.
463 Add facility to redirect some domains to the standard
464 upstream servers: this allows something like
465 --server=/google.com/1.2.3.4 --server=/www.google.com/#
466 which will send queries for *.google.com to 1.2.3.4,
467 except *www.google.com which will be forwarded as usual.
468 Thanks to AJ Weber for prompting this addition.
470 Improve the hash-algorithm used to generate IP addresses
471 from MAC addresses during initial DHCP address
472 allocation. This improves performance when large numbers
473 of hosts with similar MAC addresses all try and get an IP
474 address at the same time. Thanks to Paul Smith for his
477 Tweak DHCP code so that --bridge-interface can be used to
478 select which IP alias of an interface should be used for
479 DHCP purposes on Linux. If eth0 has an alias eth0:dhcp
480 then adding --bridge-interface=eth0:dhcp,eth0 will use
481 the address of eth0:dhcp to determine the correct subnet
482 for DHCP address allocation. Thanks to Pawel Golaszewski
483 for prompting this and Eric Cooper for further testing.
485 Add --dhcp-generate-names. Suggestion by Ferenc Wagner.
487 Tweak DNS server selection algorithm when there is more
488 than one server available for a domain, eg.
489 --server=/mydomain/1.1.1.1
490 --server=/mydomain/2.2.2.2
491 Thanks to Alberto Cuesta-Canada for spotting a weakness
494 Add --max-ttl. Thanks to Fredrik Ringertz for the patch.
496 Allow --log-facility=- to force all logging to
497 stderr. Suggestion from Clemens Fischer.
499 Fix regression which caused configuration like
500 --address=/.domain.com/1.2.3.4 to be rejected. The dot to the
501 left of the domain has been implied and not required for a
502 long time, but it should be accepted for backward
503 compatibility. Thanks to Andrew Burcin for spotting this.
505 Add --rebind-domain-ok and --rebind-localhost-ok.
506 Suggestion from Clemens Fischer.
508 Log replies to queries of type TXT, when --log-queries
511 Fix compiler warnings when compiled with -DNO_DHCP. Thanks
512 to Shantanu Gadgil for the patch.
514 Updated French translation. Thanks to Gildas Le Nadan.
516 Updated Polish translation. Thanks to Jan Psota.
518 Updated German translation. Thanks to Matthias Andree.
520 Added contrib/static-arp, thanks to Darren Hoo.
522 Fix corruption of the domain when a name from /etc/hosts
523 overrides one supplied by a DHCP client. Thanks to Fedor
524 Kozhevnikov for spotting the problem.
526 Updated Spanish translation. Thanks to Chris Chatham.
530 Work around a Linux kernel bug which insists that the
531 length of the option passed to setsockopt must be at least
532 sizeof(int) bytes, even if we're calling SO_BINDTODEVICE
533 and the device name is "lo". Note that this is fixed
534 in kernel 2.6.31, but the workaround is harmless and
535 allows earlier kernels to be used. Also fix dnsmasq
536 bug which reported the wrong address when this failed.
537 Thanks to Fedor for finding this.
539 The API for IPv6 PKTINFO changed around Linux kernel
540 2.6.14. Workaround the case where dnsmasq is compiled
541 against newer headers, but then run on an old kernel:
542 necessary for some *WRT distros.
544 Re-read the set of network interfaces when re-loading
545 /etc/resolv.conf if --bind-interfaces is not set. This
546 handles the case that loopback interfaces do not exist
547 when dnsmasq is first started.
549 Tweak the PXE code to support port 4011. This should
550 reduce broadcasts and make things more reliable when other
551 servers are around. It also improves inter-operability
552 with certain clients.
554 Make a pxe-service configuration with no filename or boot
555 service type legal: this does a local boot. eg.
556 pxe-service=x86PC, "Local boot"
558 Be more conservative in detecting "A for A"
559 queries. Dnsmasq checks if the name in a type=A query looks
560 like a dotted-quad IP address and answers the query itself
561 if so, rather than forwarding it. Previously dnsmasq
562 relied in the library function inet_addr() to convert
563 addresses, and that will accept some things which are
564 confusing in this context, like 1.2.3 or even just
565 1234. Now we only do A for A processing for four decimal
566 numbers delimited by dots.
568 A couple of tweaks to fix compilation on Solaris. Thanks
569 to Joel Macklow for help with this.
571 Another Solaris compilation tweak, needed for Solaris
572 2009.06. Thanks to Lee Essen for that.
574 Added extract packaging stuff from Lee Essen to
577 Increased the default limit on number of leases to 1000
578 (from 150). This is mainly a defence against DoS attacks,
579 and for the average "one for two class C networks"
580 installation, IP address exhaustion does that just as
581 well. Making the limit greater than the number of IP
582 addresses available in such an installation removes a
583 surprise which otherwise can catch people out.
585 Removed extraneous trailing space in the value of the
586 DNSMASQ_TIME_REMAINING DNSMASQ_LEASE_LENGTH and
587 DNSMASQ_LEASE_EXPIRES environment variables. Thanks to
588 Gildas Le Nadan for spotting this.
590 Provide the network-id tags for a DHCP transaction to
591 the lease-change script in the environment variable
592 DNSMASQ_TAGS. A good suggestion from Gildas Le Nadan.
594 Add support for RFC3925 "Vendor-Identifying Vendor
595 Options". The syntax looks like this:
596 --dhcp-option=vi-encap:<enterprise number>, .........
598 Add support to --dhcp-match to allow matching against
599 RFC3925 "Vendor-Identifying Vendor Classes". The syntax
601 --dhcp-match=tag,vi-encap<enterprise number>, <value>
603 Add some application specific code to assist in
604 implementing the Broadband forum TR069 CPE-WAN
605 specification. The details are in contrib/CPE-WAN/README
607 Increase the default DNS packet size limit to 4096, as
608 recommended by RFC5625 section 4.4.3. This can be
609 reconfigured using --edns-packet-max if needed. Thanks to
610 Francis Dupont for pointing this out.
612 Rewrite query-ids even for TSIG signed packets, since
613 this is allowed by RFC5625 section 4.5.
615 Use getopt_long by default on OS X. It has been supported
616 since version 10.3.0. Thanks to Arek Dreyer for spotting
619 Added up-to-date startup configuration for MacOSX/launchd
620 in contrib/MacOSX-launchd. Thanks to Arek Dreyer for
623 Fix link error when including Dbus but excluding DHCP.
624 Thanks to Oschtan for the bug report.
626 Updated French translation. Thanks to Gildas Le Nadan.
628 Updated Polish translation. Thanks to Jan Psota.
630 Updated Spanish translation. Thanks to Chris Chatham.
632 Fixed confusion about domains, when looking up DHCP hosts
633 in /etc/hosts. This could cause spurious "Ignoring
634 domain..." messages. Thanks to Fedor Kozhevnikov for
635 finding and analysing the problem.
639 Add support for internationalised DNS. Non-ASCII characters
640 in domain names found in /etc/hosts, /etc/ethers and
641 /etc/dnsmasq.conf will be correctly handled by translation to
642 punycode, as specified in RFC3490. This function is only
643 available if dnsmasq is compiled with internationalisation
644 support, and adds a dependency on GNU libidn. Without i18n
645 support, dnsmasq continues to be compilable with just
646 standard tools. Thanks to Yves Dorfsman for the
649 Add two more environment variables for lease-change scripts:
650 First, DNSMASQ_SUPPLIED_HOSTNAME; this is set to the hostname
651 supplied by a client, even if the actual hostname used is
652 over-ridden by dhcp-host or dhcp-ignore-names directives.
653 Also DNSMASQ_RELAY_ADDRESS which gives the address of
654 a DHCP relay, if used.
655 Suggestions from Michael Rack.
657 Fix regression which broke echo of relay-agent
658 options. Thanks to Michael Rack for spotting this.
660 Don't treat option 67 as being interchangeable with
661 dhcp-boot parameters if it's specified as
664 Make the code to call scripts on lease-change compile-time
665 optional. It can be switched off by editing src/config.h
666 or building with "make COPTS=-DNO_SCRIPT".
668 Make the TFTP server cope with filenames from Windows/DOS
669 which use '\' as pathname separator. Thanks to Ralf for
672 Updated Polish translation. Thanks to Jan Psota.
674 Warn if an IP address is duplicated in /etc/ethers. Thanks
675 to Felix Schwarz for pointing this out.
677 Teach --conf-dir to take an option list of file suffices
678 which will be ignored when scanning the directory. Useful
679 for backup files etc. Thanks to Helmut Hullen for the
682 Add new DHCP option named tftpserver-address, which
683 corresponds to the third argument of dhcp-boot. This
684 allows the complete functionality of dhcp-boot to be
685 replicated with dhcp-option. Useful when using
688 Test which upstream nameserver to use every 10 seconds
689 or 50 queries and not just when a query times out and
690 is retried. This should improve performance when there
691 is a slow nameserver in the list. Thanks to Joe for the
694 Don't do any PXE processing, even for clients with the
695 correct vendorclass, unless at least one pxe-prompt or
696 pxe-service option is given. This stops dnsmasq
697 interfering with proxy PXE subsystems when it is just
698 the DHCP server. Thanks to Spencer Clark for spotting this.
700 Limit the blocksize used for TFTP transfers to a value
701 which avoids packet fragmentation, based on the MTU of the
702 local interface. Many netboot ROMs can't cope with
705 Honour dhcp-ignore configuration for PXE and proxy-PXE
706 requests. Thanks to Niels Basjes for the bug report.
708 Updated French translation. Thanks to Gildas Le Nadan.
712 Fix security problem which allowed any host permitted to
713 do TFTP to possibly compromise dnsmasq by remote buffer
714 overflow when TFTP enabled. Thanks to Core Security
715 Technologies and Iván Arce, Pablo Hernán Jorge, Alejandro
716 Pablo Rodriguez, Martín Coco, Alberto Soliño Testa and
717 Pablo Annetta. This problem has Bugtraq id: 36121
720 Fix a problem which allowed a malicious TFTP client to
721 crash dnsmasq. Thanks to Steve Grubb at Red Hat for
722 spotting this. This problem has Bugtraq id: 36120 and
727 Fix regression in 2.48 which disables the lease-change
728 script. Thanks to Jose Luis Duran for spotting this.
730 Log TFTP "file not found" errors. These were not logged,
731 since a normal PXELinux boot generates many of them, but
732 the lack of the messages seems to be more confusing than
733 routinely seeing them when there is no real error.
735 Update Spanish translation. Thanks to Chris Chatham.
739 Archived the extensive, backwards, changelog to
740 CHANGELOG.archive. The current changelog now runs from
741 version 2.43 and runs conventionally.
743 Fixed bug which broke binding of servers to physical
744 interfaces when interface names were longer than four
745 characters. Thanks to MURASE Katsunori for the patch.
747 Fixed netlink code to check that messages come from the
748 correct source, and not another userspace process. Thanks
749 to Steve Grubb for the patch.
751 Maintainability drive: removed bug and missing feature
752 workarounds for some old platforms. Solaris 9, OpenBSD
753 older than 4.1, Glibc older than 2.2, Linux 2.2.x and
754 DBus older than 1.1.x are no longer supported.
756 Don't read included configuration files more than once:
757 allows complex configuration structures without problems.
759 Mark log messages from the various subsystems in dnsmasq:
760 messages from the DHCP subsystem now have the ident string
761 "dnsmasq-dhcp" and messages from TFTP have ident
762 "dnsmasq-tftp". Thanks to Olaf Westrik for the patch.
764 Fix possible infinite DHCP protocol loop when an IP
765 address nailed to a hostname (not a MAC address) and a
766 host sometimes provides the name, sometimes not.
768 Allow --addn-hosts to take a directory: all the files
769 in the directory are read. Thanks to Phil Cornelius for
772 Support --bridge-interface on all platforms, not just BSD.
774 Added support for advanced PXE functions. It's now
775 possible to define a prompt and menu options which will
776 be displayed when a client PXE boots. It's also possible to
777 hand-off booting to other boot servers. Proxy-DHCP, where
778 dnsmasq just supplies the PXE information and another DHCP
779 server does address allocation, is also allowed. See the
780 --pxe-prompt and --pxe-service keywords. Thanks to
781 Alkis Georgopoulos for the suggestion and Guilherme Moro
782 and Michael Brown for assistance.
784 Improvements to DHCP logging. Thanks to Tom Metro for
787 Add ability to build dnsmasq without DHCP support. To do
788 this, edit src/config.h or build with
789 "make COPTS=-DNO_DHCP". Thanks to Mahavir Jain for the patch.
791 Added --test command-line switch - syntax check
792 configuration files only.
794 Updated French translation. Thanks to Gildas Le Nadan.
798 Updated French translation. Thanks to Gildas Le Nadan.
800 Fixed interface enumeration code to work on NetBSD
801 5.0. Thanks to Roy Marples for the patch.
803 Updated config.h to use the same location for the lease
804 file on NetBSD as the other *BSD variants. Also allow
805 LEASEFILE and CONFFILE symbols to be overriden in CFLAGS.
807 Handle duplicate address detection on IPv6 more
808 intelligently. In IPv6, an interface can have an address
809 which is not usable, because it is still undergoing DAD
810 (such addresses are marked "tentative"). Attempting to
811 bind to an address in this state returns an error,
812 EADDRNOTAVAIL. Previously, on getting such an error,
813 dnsmasq would silently abandon the address, and never
814 listen on it. Now, it retries once per second for 20
815 seconds before generating a fatal error. 20 seconds should
816 be long enough for any DAD process to complete, but can be
817 adjusted in src/config.h if necessary. Thanks to Martin
818 Krafft for the bug report.
820 Add DBus introspection. Patch from Jeremy Laine.
822 Update Dbus configuration file. Patch from Colin Walters.
824 http://bugs.freedesktop.org/show_bug.cgi?id=18961
826 Support arbitrarily encapsulated DHCP options, suggestion
827 and initial patch from Samium Gromoff. This is useful for
828 (eg) gPXE, which expect all its private options to be
829 encapsulated inside a single option 175. So, eg,
831 dhcp-option = encap:175, 190, "iscsi-client0"
832 dhcp-option = encap:175, 191, "iscsi-client0-secret"
834 will provide iSCSI parameters to gPXE.
836 Enhance --dhcp-match to allow testing of the contents of a
837 client-sent option, as well as its presence. This
838 application in mind for this is RFC 4578
839 client-architecture specifiers, but it's generally useful.
840 Joey Korkames suggested the enhancement.
842 Move from using the IP_XMIT_IF ioctl to IP_BOUND_IF on
843 OpenSolaris. Thanks to Bastian Machek for the heads-up.
845 No longer complain about blank lines in
846 /etc/ethers. Thanks to Jon Nelson for the patch.
848 Fix binding of servers to physical devices, eg
849 --server=/domain/1.2.3.4@eth0 which was broken from 2.43
850 onwards unless --query-port=0 set. Thanks to Peter Naulls
853 Reply to DHCPINFORM requests even when the supplied ciaddr
854 doesn't fall in any dhcp-range. In this case it's not
855 possible to supply a complete configuration, but
856 individually-configured options (eg PAC) may be useful.
858 Allow the source address of an alias to be a range:
859 --alias=192.168.0.0,10.0.0.0,255.255.255.0 maps the whole
860 subnet 192.168.0.0->192.168.0.255 to 10.0.0.0->10.0.0.255,
862 --alias=192.168.0.10-192.168.0.40,10.0.0.0,255.255.255.0
863 maps only the 192.168.0.10->192.168.0.40 region. Thanks to
864 Ib Uhrskov for the suggestion.
866 Don't dynamically allocate DHCP addresses which may break
867 Windows. Addresses which end in .255 or .0 are broken in
868 Windows even when using supernetting.
869 --dhcp-range=192.168.0.1,192.168.1.254,255,255,254.0 means
870 192.168.0.255 is a valid IP address, but not for Windows.
871 See Microsoft KB281579. We therefore no longer allocate
872 these addresses to avoid hard-to-diagnose problems.
874 Update Polish translation. Thanks to Jan Psota.
876 Delete the PID-file when dnsmasq shuts down. Note that by
877 this time, dnsmasq is normally not running as root, so
878 this will fail if the PID-file is stored in a root-owned
879 directory; such failure is silently ignored. To take
880 advantage of this feature, the PID-file must be stored in a
881 directory owned and write-able by the user running
886 Allow --bootp-dynamic to take a netid tag, so that it may
887 be selectively enabled. Thanks to Olaf Westrik for the
890 Remove ISC-leasefile reading code. This has been
891 deprecated for a long time, and last time I removed it, it
892 ended up going back by request of one user. This time,
893 it's gone for good; otherwise it would need to be
894 re-worked to support multiple domains (see below).
896 Support DHCP clients in multiple DNS domains. This is a
897 long-standing request. Clients are assigned to a domain
898 based in their IP address.
900 Add --dhcp-fqdn flag, which changes behaviour if DNS names
901 assigned to DHCP clients. When this is set, there must be
902 a domain associated with each client, and only
903 fully-qualified domain names are added to the DNS. The
904 advantage is that the only the FQDN needs to be unique,
905 so that two or more DHCP clients can share a hostname, as
906 long as they are in different domains.
908 Set environment variable DNSMASQ_DOMAIN when invoking
909 lease-change script. This may be useful information to
910 have now that it's variable.
912 Tighten up data-checking code for DNS packet
913 handling. Thanks to Steve Dodd who found certain illegal
914 packets which could crash dnsmasq. No memory overwrite was
915 possible, so this is not a security issue beyond the DoS
918 Update example config dhcp option 47, the previous
919 suggestion generated an illegal, zero-length,
920 option. Thanks to Matthias Andree for finding this.
922 Rewrite hosts-file reading code to remove the limit of
923 1024 characters per line. John C Meuser found this.
925 Create a net-id tag with the name of the interface on
926 which the DHCP request was received.
928 Fixed minor memory leak in DBus code, thanks to Jeremy
931 Emit DBus signals as the DHCP lease database
932 changes. Thanks to Jeremy Laine for the patch.
934 Allow for more that one MAC address in a dhcp-host
935 line. This configuration tells dnsmasq that it's OK to
936 abandon a DHCP lease of the fixed address to one MAC
937 address, if another MAC address in the dhcp-host statement
938 asks for an address. This is useful to give a fixed
939 address to a host which has two network interfaces
940 (say, a laptop with wired and wireless interfaces.)
941 It's very important to ensure that only one interface
942 at a time is up, since dnsmasq abandons the first lease
943 and re-uses the address before the leased time has
944 elapsed. John Gray suggested this.
946 Tweak the response to a DHCP request packet with a wrong
947 server-id when --dhcp-authoritative is set; dnsmasq now
948 returns a DHCPNAK, rather than silently ignoring the
949 packet. Thanks to Chris Marget for spotting this
952 Add --cname option. This provides a limited alias
953 function, usable for DHCP names. Thanks to AJ Weber for
956 Updated contrib/webmin with latest version from Neil
959 Updated Polish translation. Thanks to Jan Psota.
961 Correct the text names for DHCP options 64 and 65 to be
962 "nis+-domain" and "nis+-servers".
964 Updated Spanish translation. Thanks to Chris Chatham.
966 Force re-reading of /etc/resolv.conf when an "interface
971 Fix total DNS failure in release 2.44 unless --min-port
972 specified. Thanks to Steven Barth and Grant Coady for
973 bugreport. Also reject out-of-range port spec, which could
974 break things too: suggestion from Gilles Espinasse.
978 Fix crash when unknown client attempts to renew a DHCP
979 lease, problem introduced in version 2.43. Thanks to
980 Carlos Carvalho for help chasing this down.
982 Fix potential crash when a host which doesn't have a lease
983 does DHCPINFORM. Again introduced in 2.43. This bug has
984 never been reported in the wild.
986 Fix crash in netlink code introduced in 2.43. Thanks to
987 Jean Wolter for finding this.
989 Change implementation of min_port to work even if min-port
992 Patch to enable compilation of latest Mac OS X. Thanks to
995 Update Spanish translation. Thanks to Christopher Chatham.
999 Updated Polish translation. Thanks to Jan Psota.
1001 Flag errors when configuration options are repeated
1004 Further tweaks for GNU/kFreeBSD
1006 Add --no-wrap to msgmerge call - provides nicer .po file
1009 Honour lease-time spec in dhcp-host lines even for
1010 BOOTP. The user is assumed to known what they are doing in
1011 this case. (Hosts without the time spec still get infinite
1012 leases for BOOTP, over-riding the default in the
1013 dhcp-range.) Thanks to Peter Katzmann for uncovering this.
1015 Fix problem matching relay-agent ids. Thanks to Michael
1016 Rack for the bug report.
1018 Add --naptr-record option. Suggestion from Johan
1021 Implement RFC 5107 server-id-override DHCP relay agent
1024 Apply patches from Stefan Kruger for compilation on
1025 Solaris 10 under Sun studio.
1027 Yet more tweaking of Linux capability code, to suppress
1028 pointless wingeing from kernel 2.6.25 and above.
1030 Improve error checking during startup. Previously, some
1031 errors which occurred during startup would be worked
1032 around, with dnsmasq still starting up. Some were logged,
1033 some silent. Now, they all cause a fatal error and dnsmasq
1034 terminates with a non-zero exit code. The errors are those
1035 associated with changing uid and gid, setting process
1036 capabilities and writing the pidfile. Thanks to Uwe
1037 Gansert and the Suse security team for pointing out
1038 this improvement, and Bill Reimers for good implementation
1041 Provide NO_LARGEFILE compile option to switch off largefile
1042 support when compiling against versions of uclibc which
1043 don't support it. Thanks to Stephane Billiart for the patch.
1045 Implement random source ports for interactions with
1046 upstream nameservers. New spoofing attacks have been found
1047 against nameservers which do not do this, though it is not
1048 clear if dnsmasq is vulnerable, since to doesn't implement
1049 recursion. By default dnsmasq will now use a different
1050 source port (and socket) for each query it sends
1051 upstream. This behaviour can suppressed using the
1052 --query-port option, and the old default behaviour
1053 restored using --query-port=0. Explicit source-port
1054 specifications in --server configs are still honoured.
1056 Replace the random number generator, for better
1057 security. On most BSD systems, dnsmasq uses the
1058 arc4random() RNG, which is secure, but on other platforms,
1059 it relied on the C-library RNG, which may be
1060 guessable and therefore allow spoofing. This release
1061 replaces the libc RNG with the SURF RNG, from Daniel
1062 J. Berstein's DJBDNS package.
1064 Don't attempt to change user or group or set capabilities
1065 if dnsmasq is run as a non-root user. Without this, the
1066 change from soft to hard errors when these fail causes
1067 problems for non-root daemons listening on high
1068 ports. Thanks to Patrick McLean for spotting this.
1070 Updated French translation. Thanks to Gildas Le Nadan.
1074 The changelog for version 2.42 and earlier is
1075 available in CHANGELOG.archive.
