2 Fix compilation problem in Mac OS X Lion. Thanks to Olaf
5 Fix DHCP when using --listen-address with an IP address
6 which is not the primary address of an interface.
8 Add --dhcp-client-update option.
10 Add Lua integration. Dnsmasq can now execute a DHCP
11 lease-change script written in Lua. This needs to be
12 enabled at compile time by setting HAVE_LUASCRIPT in
13 src/config.h or running "make COPTS=-DHAVE_LUASCRIPT"
14 Thanks to Jan-Piet Mens for the idea and proof-of-concept
17 Tidied src/config.h to distinguish between
18 platform-dependent compile-time options which are selected
19 automatically, and builder-selectable compile time
20 options. Document the latter better, and describe how to
21 set them from the make command line.
23 Tidied up IPPROTO_IP/SOL_IP (and IPv6 equivalent)
24 confusion. IPPROTO_IP works everywhere now.
26 Set TOS on DHCP sockets, this improves things on busy
27 wireless networks. Thanks to Dave Taht for the patch.
29 Determine VERSION automatically based on git magic:
30 release tags or hash values.
32 Improve start-up speed when reading large hosts files
33 containing many distinct addresses.
35 Fix problem if dnsmasq is started without the stdin,
36 stdout and stderr file descriptors open. This can manifest
37 itself as 100% CPU use. Thanks to Chris Moore for finding
40 Fix shell-scripting bug in bld/pkg-wrapper. Thanks to
41 Mark Mitchell for the patch.
43 Allow the TFP server or boot server in --pxe-service, to
44 be a domain name instead of an IP address. This allows for
45 round-robin to multiple servers, in the same way as
46 --dhcp-boot. A good suggestion from Cristiano Cumer.
48 Support BUILDDIR variable in the Makefile. Allows builds
49 for multiple archs from the same source tree with eg.
50 make BUILDDIR=linux (relative to dnsmasq tree)
51 make BUILDDIR=/tmp/openbsd (absolute path)
52 If BUILDDIR is not set, compilation happens in the src
53 directory, as before. Suggestion from Mark Mitchell.
55 Support DHCPv6. Support is there for the sort of things
56 the existing v4 server does, including tags, options,
57 static addresses and relay support. Missing is prefix
58 delegation, which is probably not required in the dnsmasq
59 niche, and an easy way to accept prefix delegations from
60 an upstream DHCPv6 server, which is. Future plans include
61 support for DHCPv6 router option and MAC address option
62 (to make selecting clients by MAC address work like IPv4).
63 These will be added as the standards mature.
64 This code has been tested, but this is the first release,
65 so don't bet the farm on it just yet. Many thanks to all
66 testers who have got it this far.
68 Support IPv6 router advertisements. This is a
69 simple-minded implementation, aimed at providing the
70 vestigial RA needed to go alongside IPv6. Is picks up
71 configuration from the DHCPv6 conf, and should just need
72 enabling with --enable-ra.
74 Fix long-standing wrinkle with --localise-queries that
75 could result in wrong answers when DNS packets arrive
76 via an interface other than the expected one. Thanks to
77 Lorenzo Milesi and John Hanks for spotting this one.
79 Update French translation. Thanks to Gildas Le Nadan.
83 Fix regression in 2.58 which caused failure to start up
84 with some combinations of dnsmasq config and IPv6 kernel
85 network config. Thanks to Brielle Bruns for the bug
88 Improve dnsmasq's behaviour when network interfaces are
89 still doing duplicate address detection (DAD). Previously,
90 dnsmasq would wait up to 20 seconds at start-up for the
91 DAD state to terminate. This is broken for bridge
92 interfaces on recent Linux kernels, which don't start DAD
93 until the bridge comes up, and so can take arbitrary
94 time. The new behaviour lets dnsmasq poll for an arbitrary
95 time whilst providing service on other interfaces. Thanks
96 to Stephen Hemminger for pointing out the problem.
100 Provide a definition of the SA_SIZE macro where it's
101 missing. Fixes build failure on openBSD.
103 Don't include a zero terminator at the end of messages
104 sent to /dev/log when /dev/log is a datagram socket.
105 Thanks to Didier Rabound for spotting the problem.
107 Add --dhcp-sequential-ip flag, to force allocation of IP
108 addresses in ascending order. Note that the default
109 pseudo-random mode is in general better but some
110 server-deployment applications need this.
112 Fix problem where a server-id of 0.0.0.0 is sent to a
113 client when a dhcp-relay is in use if a client renews a
114 lease after dnsmasq restart and before any clients on the
115 subnet get a new lease. Thanks to Mike Ruiz for assistance
116 in chasing this one down.
118 Don't return NXDOMAIN to an AAAA query if we have CNAME
119 which points to an A record only: NODATA is the correct
120 reply in this case. Thanks to Tom Fernandes for spotting
123 Relax the need to supply a netmask in --dhcp-range for
124 networks which use a DHCP relay. Whilst this is still
125 desireable, in the absence of a netmask dnsmasq will use
126 a default based on the class (A, B, or C) of the address.
127 This should at least remove a cause of mysterious failure
128 for people using RFC1918 addresses and relays.
130 Add support for Linux conntrack connection marking. If
131 enabled with --conntrack, the connection mark for incoming
132 DNS queries will be copied to the outgoing connections
133 used to answer those queries. This allows clever firewall
134 and accounting stuff. Only available if dnsmasq is
135 compiled with HAVE_CONNTRACK and adds a dependency on
136 libnetfilter-conntrack. Thanks to Ed Wildgoose for the
137 initial idea, testing and sponsorship of this function.
139 Provide a sane error message when someone attempts to
140 match a tag in --dhcp-host.
142 Tweak the behaviour of --domain-needed, to avoid problems
143 with recursive nameservers downstream of dnsmasq. The new
144 behaviour only stops A and AAAA queries, and returns
145 NODATA rather than NXDOMAIN replies.
147 Efficiency fix for very large DHCP configurations, thanks
148 to James Gartrell and Mike Ruiz for help with this.
150 Allow the TFTP-server address in --dhcp-boot to be a
151 domain-name which is looked up in /etc/hosts. This can
152 give multiple IP addresses which are used round-robin,
153 thus doing TFTP server load-balancing. Thanks to Sushil
154 Agrawal for the patch.
156 When two tagged dhcp-options for a particular option
157 number are both valid, use the one which is valid without
158 a tag from the dhcp-range. Allows overriding of the value
159 of a DHCP option for a particular host as well as
160 per-network values. So
161 --dhcp-range=set:interface1,......
162 --dhcp-host=set:myhost,.....
163 --dhcp-option=tag:interface1,option:nis-domain,"domain1"
164 --dhcp-option=tag:myhost,option:nis-domain,"domain2"
165 will set the NIS-domain to domain1 for hosts in the range, but
166 override that to domain2 for a particular host.
168 Fix bug which resulted in truncated files and timeouts for
169 some TFTP transfers. The bug only occurs with netascii
170 transfers and needs an unfortunate relationship between
171 file size, blocksize and the number of newlines in the
172 last block before it manifests itself. Many thanks to
173 Alkis Georgopoulos for spotting the problem and providing
174 a comprehensive test-case.
176 Fix regression in TFTP server on *BSD platforms introduced
177 in version 2.56, due to confusion with sockaddr
178 length. Many thanks to Loïc Pefferkorn for finding this.
180 Support scope-ids in IPv6 addresses of nameservers from
181 /etc/resolv.conf and in --server options. Eg
182 nameserver fe80::202:a412:4512:7bbf%eth0 or
183 server=fe80::202:a412:4512:7bbf%eth0. Thanks to
184 Michael Stapelberg for the suggestion.
186 Update Polish translation, thanks to Jan Psota.
188 Update French translation. Thanks to Gildas Le Nadan.
192 Add patches to allow build under Android.
194 Provide our own header for the DNS protocol, rather than
195 relying on arpa/nameser.h. This has proved more or less
196 defective over the years and the final straw is that it's
197 effectively empty on Android.
199 Fix regression in 2.56 which caused hex constants in
200 configuration to be rejected if they contain the '*'
203 Correct wrong casts of arguments to ctype.h functions,
204 isdigit(), isxdigit() etc. Thanks to Matthias Andree for
207 Allow build with IDN support independently from i18n.
208 IDN support continues to be included automatically
209 when i18n is included.
210 'make COPTS=-DHAVE_IDN' is the magic incantation.
212 Modify check on extraneous command line junk (added in
213 2.56) so that it doesn't complain about extra _empty_
214 arguments. Otherwise this breaks libvirt.
218 Add a patch to allow dnsmasq to get interface names right in a
219 Solaris zone. Thanks to Dj Padzensky for this.
221 Improve data-type parsing heuristics so that
222 --dhcp-option=option:domain-search,.
223 treats the value as a string and not an IP address.
224 Thanks to Clemens Fischer for spotting that.
226 Add IPv6 support to the TFTP server. Many thanks to Jan
227 'RedBully' Seiffert for the patches.
229 Log DNS queries at level LOG_INFO, rather then
230 LOG_DEBUG. This makes things consistent with DHCP
231 logging. Thanks to Adam Pribyl for spotting the problem.
233 Ensure that dnsmasq terminates cleanly when using
234 --syslog-async even if it cannot make a connection to the
237 Add --add-mac option. This is to support currently
238 experimental DNS filtering facilities. Thanks to Benjamin
239 Petrin for the orignal patch.
241 Fix bug which meant that tags were ignored in dhcp-range
242 configuration specifying PXE-proxy service. Thanks to
243 Cristiano Cumer for spotting this.
245 Raise an error if there is extra junk, not part of an
246 option, on the command line.
248 Flag a couple of log messages in cache.c as coming from
249 the DHCP subsystem. Thanks to Olaf Westrik for the patch.
251 Omit timestamps from logs when a) logging to stderr and
252 b) --keep-in-forground is set. The logging facility on the
253 other end of stderr can be assumned to supply them. Thanks
254 to John Hallam for the patch.
256 Don't complain about strings longer than 255 characters in
257 --txt-record, just split the long strings into 255
258 character chunks instead.
260 Fix crash on double-free. This bug can only happen when
261 dhcp-script is in use and then only in rare circumstances
262 triggered by high DHCP transaction rate and a slow
263 script. Thanks to Ferenc Wagner for finding the problem.
265 Only log that a file has been sent by TFTP after the
266 transfer has completed succesfully.
268 A good suggestion from Ferenc Wagner: extend
269 the --domain option to allow this sort of thing:
270 --domain=thekelleys.org.uk,192.168.0.0/24,local
271 which automatically creates
272 --local=/thekelleys.org.uk/
273 --local=/0.168.192.in-addr.arpa/
275 Tighten up syntax checking of hex contants in the config
276 file. Thanks to Fred Damen for spotting this.
278 Add dnsmasq logo/icon, contributed by Justin Swift. Many
281 Never cache DNS replies which have the 'cd' bit set, or
282 which result from queries forwarded with the 'cd' bit
283 set. The 'cd' bit instructs a DNSSEC validating server
284 upstream to ignore signature failures and return replies
285 anyway. Without this change it's possible to pollute the
286 dnsmasq cache with bad data by making a query with the
287 'cd' bit set and subsequent queries would return this data
288 without its being marked as suspect. Thanks to Anders
289 Kaseorg for pointing out this problem.
291 Add --proxy-dnssec flag, for compliance with RFC
292 4035. Dnsmasq will now clear the 'ad' bit in answers returned
293 from upstream validating nameservers unless this option is
296 Allow a filename of "-" for --conf-file to read
297 stdin. Suggestion from Timothy Redaelli.
299 Rotate the order of SRV records in replies, to provide
300 round-robin load balancing when all the priorities are
301 equal. Thanks to Peter McKinney for the suggestion.
304 contrib/MacOSX-launchd/uk.org.thekelleys.dnsmasq.plist
305 so that it doesn't log all queries to a file by
306 default. Thanks again to Peter McKinney.
308 By default, setting an IPv4 address for a domain but not
309 an IPv6 address causes dnsmasq to return
310 an NODATA reply for IPv6 (or vice-versa). So
311 --address=/google.com/1.2.3.4 stops IPv6 queries for
312 *google.com from being forwarded. Make it possible to
313 override this behaviour by defining the sematics if the
314 same domain appears in both --server and --address.
315 In that case, the --address has priority for the address
316 family in which is appears, but the --server has priority
317 of the address family which doesn't appear in --adddress
319 --address=/google.com/1.2.3.4
320 --server=/google.com/#
321 will return 1.2.3.4 for IPv4 queries for *.google.com but
322 forward IPv6 queries to the normal upstream nameserver.
323 Similarly when setting an IPv6 address
324 only this will allow forwarding of IPv4 queries. Thanks to
325 William for pointing out the need for this.
327 Allow more than one --dhcp-optsfile and --dhcp-hostsfile
328 and make them understand directories as arguments in the
329 same way as --addn-hosts. Suggestion from John Hanks.
331 Ignore rebinding requests for leases we don't know
332 about. Rebind is broadcast, so we might get to overhear a
333 request meant for another DHCP server. NAKing this is
334 wrong. Thanks to Brad D'Hondt for assistance with this.
336 Fix cosmetic bug which produced strange output when
337 dumping cache statistics with some configurations. Thanks
338 to Fedor Kozhevnikov for spotting this.
342 Fix crash when /etc/ethers is in use. Thanks to
343 Gianluigi Tiesi for finding this.
345 Fix crash in netlink_multicast(). Thanks to Arno Wald for
348 Allow the empty domain "." in dhcp domain-search (119)
353 There is no version 2.54 to avoid confusion with 2.53,
354 which incorrectly identifies itself as 2.54.
358 Fix failure to compile on Debian/kFreeBSD. Thanks to
359 Axel Beckert and Petr Salinger.
361 Fix code to avoid scary strict-aliasing warnings
362 generated by gcc 4.4.
364 Added FAQ entry warning about DHCP failures with Vista
365 when firewalls block 255.255.255.255.
367 Fixed bug which caused bad things to happen if a
368 resolv.conf file which exists is subsequently removed.
369 Thanks to Nikolai Saoukh for the patch.
371 Rationalised the DHCP tag system. Every configuration item
372 which can set a tag does so by adding "set:<tag>" and
373 every configuration item which is conditional on a tag is
374 made so by "tag:<tag>". The NOT operator changes to '!',
375 which is a bit more intuitive too. Dhcp-host directives
376 can set more than one tag now. The old '#' NOT,
377 "net:" prefix and no-prefixes are still honoured, so
378 no existing config file needs to be changed, but
379 the documentation and new-style config files should be
382 Added --tag-if to allow boolean operations on tags.
383 This allows complicated logic to be clearer and more
384 general. A great suggestion from Richard Voigt.
386 Add broadcast/unicast information to DHCP logging.
388 Allow --dhcp-broadcast to be unconditional.
390 Fixed incorrect behaviour with NOT <tag> conditionals in
391 dhcp-options. Thanks to Max Turkewitz for assistance
394 If we send vendor-class encapsulated options based on the
395 vendor-class supplied by the client, and no explicit
396 vendor-class option is given, echo back the vendor-class
399 Fix bug which stopped dnsmasq from matching both a
400 circuitid and a remoteid. Thanks to Ignacio Bravo for
403 Add --dhcp-proxy, which makes it possible to configure
404 dnsmasq to use a DHCP relay agent as a full proxy, with
405 all DHCP messages passing through the proxy. This is
406 useful if the relay adds extra information to the packets
407 it forwards, but cannot be configured with the RFC 5107
408 server-override option.
410 Added interface:<iface name> part to dhcp-range. The
411 semantics of this are very odd at first sight, but it
412 allows a single line of the form
413 dhcp-range=interface:virt0,192.168.0.4,192.168.0.200
414 to be added to dnsmasq configuration which then supplies
415 DHCP and DNS services to that interface, without affecting
416 what services are supplied to other interfaces and
417 irrespective of the existance or lack of
418 interface=<interface>
419 lines elsewhere in the dnsmasq configuration. The idea is
420 that such a line can be added automatically by libvirt
421 or equivalent systems, without disturbing any manual
424 Similarly to the above, allow --enable-tftp=<interface>
426 Allow a TFTP root to be set separately for requests via
427 different interfaces, --tftp-root=<path>,<interface>
429 Correctly handle and log clashes between CNAMES and
430 DNS names being given to DHCP leases. This fixes a bug
431 which caused nonsense IP addresses to be logged. Thanks to
432 Sergei Zhirikov for finding and analysing the problem.
434 Tweak flush_log so as to avoid leaving the log
435 file in non-blocking mode. O_NONBLOCK is a property of the
436 file, not the process/descriptor.
438 Fix contrib/Solaris10/create_package
439 (/usr/man -> /usr/share/man) Thanks to Vita Batrla.
441 Fix a problem where, if a client got a lease, then went
442 to another subnet and got another lease, then moved back,
443 it couldn't resume the old lease, but would instead get
444 a new address. Thanks to Leonardo Rodrigues for spotting
445 this and testing the fix.
447 Fix weird bug which sometimes omitted certain characters
448 from the start of quoted strings in dhcp-options. Thanks
449 to Dayton Turner for spotting the problem.
451 Add facility to redirect some domains to the standard
452 upstream servers: this allows something like
453 --server=/google.com/1.2.3.4 --server=/www.google.com/#
454 which will send queries for *.google.com to 1.2.3.4,
455 except *www.google.com which will be forwarded as usual.
456 Thanks to AJ Weber for prompting this addition.
458 Improve the hash-algorithm used to generate IP addresses
459 from MAC addresses during initial DHCP address
460 allocation. This improves performance when large numbers
461 of hosts with similar MAC addresses all try and get an IP
462 address at the same time. Thanks to Paul Smith for his
465 Tweak DHCP code so that --bridge-interface can be used to
466 select which IP alias of an interface should be used for
467 DHCP purposes on Linux. If eth0 has an alias eth0:dhcp
468 then adding --bridge-interface=eth0:dhcp,eth0 will use
469 the address of eth0:dhcp to determine the correct subnet
470 for DHCP address allocation. Thanks to Pawel Golaszewski
471 for prompting this and Eric Cooper for further testing.
473 Add --dhcp-generate-names. Suggestion by Ferenc Wagner.
475 Tweak DNS server selection algorithm when there is more
476 than one server available for a domain, eg.
477 --server=/mydomain/1.1.1.1
478 --server=/mydomain/2.2.2.2
479 Thanks to Alberto Cuesta-Canada for spotting a weakness
482 Add --max-ttl. Thanks to Fredrik Ringertz for the patch.
484 Allow --log-facility=- to force all logging to
485 stderr. Suggestion from Clemens Fischer.
487 Fix regression which caused configuration like
488 --address=/.domain.com/1.2.3.4 to be rejected. The dot to the
489 left of the domain has been implied and not required for a
490 long time, but it should be accepted for backward
491 compatibility. Thanks to Andrew Burcin for spotting this.
493 Add --rebind-domain-ok and --rebind-localhost-ok.
494 Suggestion from Clemens Fischer.
496 Log replies to queries of type TXT, when --log-queries
499 Fix compiler warnings when compiled with -DNO_DHCP. Thanks
500 to Shantanu Gadgil for the patch.
502 Updated French translation. Thanks to Gildas Le Nadan.
504 Updated Polish translation. Thanks to Jan Psota.
506 Updated German translation. Thanks to Matthias Andree.
508 Added contrib/static-arp, thanks to Darren Hoo.
510 Fix corruption of the domain when a name from /etc/hosts
511 overrides one supplied by a DHCP client. Thanks to Fedor
512 Kozhevnikov for spotting the problem.
514 Updated Spanish translation. Thanks to Chris Chatham.
518 Work around a Linux kernel bug which insists that the
519 length of the option passed to setsockopt must be at least
520 sizeof(int) bytes, even if we're calling SO_BINDTODEVICE
521 and the device name is "lo". Note that this is fixed
522 in kernel 2.6.31, but the workaround is harmless and
523 allows earlier kernels to be used. Also fix dnsmasq
524 bug which reported the wrong address when this failed.
525 Thanks to Fedor for finding this.
527 The API for IPv6 PKTINFO changed around Linux kernel
528 2.6.14. Workaround the case where dnsmasq is compiled
529 against newer headers, but then run on an old kernel:
530 necessary for some *WRT distros.
532 Re-read the set of network interfaces when re-loading
533 /etc/resolv.conf if --bind-interfaces is not set. This
534 handles the case that loopback interfaces do not exist
535 when dnsmasq is first started.
537 Tweak the PXE code to support port 4011. This should
538 reduce broadcasts and make things more reliable when other
539 servers are around. It also improves inter-operability
540 with certain clients.
542 Make a pxe-service configuration with no filename or boot
543 service type legal: this does a local boot. eg.
544 pxe-service=x86PC, "Local boot"
546 Be more conservative in detecting "A for A"
547 queries. Dnsmasq checks if the name in a type=A query looks
548 like a dotted-quad IP address and answers the query itself
549 if so, rather than forwarding it. Previously dnsmasq
550 relied in the library function inet_addr() to convert
551 addresses, and that will accept some things which are
552 confusing in this context, like 1.2.3 or even just
553 1234. Now we only do A for A processing for four decimal
554 numbers delimited by dots.
556 A couple of tweaks to fix compilation on Solaris. Thanks
557 to Joel Macklow for help with this.
559 Another Solaris compilation tweak, needed for Solaris
560 2009.06. Thanks to Lee Essen for that.
562 Added extract packaging stuff from Lee Essen to
565 Increased the default limit on number of leases to 1000
566 (from 150). This is mainly a defence against DoS attacks,
567 and for the average "one for two class C networks"
568 installation, IP address exhaustion does that just as
569 well. Making the limit greater than the number of IP
570 addresses available in such an installation removes a
571 surprise which otherwise can catch people out.
573 Removed extraneous trailing space in the value of the
574 DNSMASQ_TIME_REMAINING DNSMASQ_LEASE_LENGTH and
575 DNSMASQ_LEASE_EXPIRES environment variables. Thanks to
576 Gildas Le Nadan for spotting this.
578 Provide the network-id tags for a DHCP transaction to
579 the lease-change script in the environment variable
580 DNSMASQ_TAGS. A good suggestion from Gildas Le Nadan.
582 Add support for RFC3925 "Vendor-Identifying Vendor
583 Options". The syntax looks like this:
584 --dhcp-option=vi-encap:<enterprise number>, .........
586 Add support to --dhcp-match to allow matching against
587 RFC3925 "Vendor-Identifying Vendor Classes". The syntax
589 --dhcp-match=tag,vi-encap<enterprise number>, <value>
591 Add some application specific code to assist in
592 implementing the Broadband forum TR069 CPE-WAN
593 specification. The details are in contrib/CPE-WAN/README
595 Increase the default DNS packet size limit to 4096, as
596 recommended by RFC5625 section 4.4.3. This can be
597 reconfigured using --edns-packet-max if needed. Thanks to
598 Francis Dupont for pointing this out.
600 Rewrite query-ids even for TSIG signed packets, since
601 this is allowed by RFC5625 section 4.5.
603 Use getopt_long by default on OS X. It has been supported
604 since version 10.3.0. Thanks to Arek Dreyer for spotting
607 Added up-to-date startup configuration for MacOSX/launchd
608 in contrib/MacOSX-launchd. Thanks to Arek Dreyer for
611 Fix link error when including Dbus but excluding DHCP.
612 Thanks to Oschtan for the bug report.
614 Updated French translation. Thanks to Gildas Le Nadan.
616 Updated Polish translation. Thanks to Jan Psota.
618 Updated Spanish translation. Thanks to Chris Chatham.
620 Fixed confusion about domains, when looking up DHCP hosts
621 in /etc/hosts. This could cause spurious "Ignoring
622 domain..." messages. Thanks to Fedor Kozhevnikov for
623 finding and analysing the problem.
627 Add support for internationalised DNS. Non-ASCII characters
628 in domain names found in /etc/hosts, /etc/ethers and
629 /etc/dnsmasq.conf will be correctly handled by translation to
630 punycode, as specified in RFC3490. This function is only
631 available if dnsmasq is compiled with internationalisation
632 support, and adds a dependency on GNU libidn. Without i18n
633 support, dnsmasq continues to be compilable with just
634 standard tools. Thanks to Yves Dorfsman for the
637 Add two more environment variables for lease-change scripts:
638 First, DNSMASQ_SUPPLIED_HOSTNAME; this is set to the hostname
639 supplied by a client, even if the actual hostname used is
640 over-ridden by dhcp-host or dhcp-ignore-names directives.
641 Also DNSMASQ_RELAY_ADDRESS which gives the address of
642 a DHCP relay, if used.
643 Suggestions from Michael Rack.
645 Fix regression which broke echo of relay-agent
646 options. Thanks to Michael Rack for spotting this.
648 Don't treat option 67 as being interchangeable with
649 dhcp-boot parameters if it's specified as
652 Make the code to call scripts on lease-change compile-time
653 optional. It can be switched off by editing src/config.h
654 or building with "make COPTS=-DNO_SCRIPT".
656 Make the TFTP server cope with filenames from Windows/DOS
657 which use '\' as pathname separator. Thanks to Ralf for
660 Updated Polish translation. Thanks to Jan Psota.
662 Warn if an IP address is duplicated in /etc/ethers. Thanks
663 to Felix Schwarz for pointing this out.
665 Teach --conf-dir to take an option list of file suffices
666 which will be ignored when scanning the directory. Useful
667 for backup files etc. Thanks to Helmut Hullen for the
670 Add new DHCP option named tftpserver-address, which
671 corresponds to the third argument of dhcp-boot. This
672 allows the complete functionality of dhcp-boot to be
673 replicated with dhcp-option. Useful when using
676 Test which upstream nameserver to use every 10 seconds
677 or 50 queries and not just when a query times out and
678 is retried. This should improve performance when there
679 is a slow nameserver in the list. Thanks to Joe for the
682 Don't do any PXE processing, even for clients with the
683 correct vendorclass, unless at least one pxe-prompt or
684 pxe-service option is given. This stops dnsmasq
685 interfering with proxy PXE subsystems when it is just
686 the DHCP server. Thanks to Spencer Clark for spotting this.
688 Limit the blocksize used for TFTP transfers to a value
689 which avoids packet fragmentation, based on the MTU of the
690 local interface. Many netboot ROMs can't cope with
693 Honour dhcp-ignore configuration for PXE and proxy-PXE
694 requests. Thanks to Niels Basjes for the bug report.
696 Updated French translation. Thanks to Gildas Le Nadan.
700 Fix security problem which allowed any host permitted to
701 do TFTP to possibly compromise dnsmasq by remote buffer
702 overflow when TFTP enabled. Thanks to Core Security
703 Technologies and Iván Arce, Pablo Hernán Jorge, Alejandro
704 Pablo Rodriguez, Martín Coco, Alberto Soliño Testa and
705 Pablo Annetta. This problem has Bugtraq id: 36121
708 Fix a problem which allowed a malicious TFTP client to
709 crash dnsmasq. Thanks to Steve Grubb at Red Hat for
710 spotting this. This problem has Bugtraq id: 36120 and
715 Fix regression in 2.48 which disables the lease-change
716 script. Thanks to Jose Luis Duran for spotting this.
718 Log TFTP "file not found" errors. These were not logged,
719 since a normal PXELinux boot generates many of them, but
720 the lack of the messages seems to be more confusing than
721 routinely seeing them when there is no real error.
723 Update Spanish translation. Thanks to Chris Chatham.
727 Archived the extensive, backwards, changelog to
728 CHANGELOG.archive. The current changelog now runs from
729 version 2.43 and runs conventionally.
731 Fixed bug which broke binding of servers to physical
732 interfaces when interface names were longer than four
733 characters. Thanks to MURASE Katsunori for the patch.
735 Fixed netlink code to check that messages come from the
736 correct source, and not another userspace process. Thanks
737 to Steve Grubb for the patch.
739 Maintainability drive: removed bug and missing feature
740 workarounds for some old platforms. Solaris 9, OpenBSD
741 older than 4.1, Glibc older than 2.2, Linux 2.2.x and
742 DBus older than 1.1.x are no longer supported.
744 Don't read included configuration files more than once:
745 allows complex configuration structures without problems.
747 Mark log messages from the various subsystems in dnsmasq:
748 messages from the DHCP subsystem now have the ident string
749 "dnsmasq-dhcp" and messages from TFTP have ident
750 "dnsmasq-tftp". Thanks to Olaf Westrik for the patch.
752 Fix possible infinite DHCP protocol loop when an IP
753 address nailed to a hostname (not a MAC address) and a
754 host sometimes provides the name, sometimes not.
756 Allow --addn-hosts to take a directory: all the files
757 in the directory are read. Thanks to Phil Cornelius for
760 Support --bridge-interface on all platforms, not just BSD.
762 Added support for advanced PXE functions. It's now
763 possible to define a prompt and menu options which will
764 be displayed when a client PXE boots. It's also possible to
765 hand-off booting to other boot servers. Proxy-DHCP, where
766 dnsmasq just supplies the PXE information and another DHCP
767 server does address allocation, is also allowed. See the
768 --pxe-prompt and --pxe-service keywords. Thanks to
769 Alkis Georgopoulos for the suggestion and Guilherme Moro
770 and Michael Brown for assistance.
772 Improvements to DHCP logging. Thanks to Tom Metro for
775 Add ability to build dnsmasq without DHCP support. To do
776 this, edit src/config.h or build with
777 "make COPTS=-DNO_DHCP". Thanks to Mahavir Jain for the patch.
779 Added --test command-line switch - syntax check
780 configuration files only.
782 Updated French translation. Thanks to Gildas Le Nadan.
786 Updated French translation. Thanks to Gildas Le Nadan.
788 Fixed interface enumeration code to work on NetBSD
789 5.0. Thanks to Roy Marples for the patch.
791 Updated config.h to use the same location for the lease
792 file on NetBSD as the other *BSD variants. Also allow
793 LEASEFILE and CONFFILE symbols to be overriden in CFLAGS.
795 Handle duplicate address detection on IPv6 more
796 intelligently. In IPv6, an interface can have an address
797 which is not usable, because it is still undergoing DAD
798 (such addresses are marked "tentative"). Attempting to
799 bind to an address in this state returns an error,
800 EADDRNOTAVAIL. Previously, on getting such an error,
801 dnsmasq would silently abandon the address, and never
802 listen on it. Now, it retries once per second for 20
803 seconds before generating a fatal error. 20 seconds should
804 be long enough for any DAD process to complete, but can be
805 adjusted in src/config.h if necessary. Thanks to Martin
806 Krafft for the bug report.
808 Add DBus introspection. Patch from Jeremy Laine.
810 Update Dbus configuration file. Patch from Colin Walters.
812 http://bugs.freedesktop.org/show_bug.cgi?id=18961
814 Support arbitrarily encapsulated DHCP options, suggestion
815 and initial patch from Samium Gromoff. This is useful for
816 (eg) gPXE, which expect all its private options to be
817 encapsulated inside a single option 175. So, eg,
819 dhcp-option = encap:175, 190, "iscsi-client0"
820 dhcp-option = encap:175, 191, "iscsi-client0-secret"
822 will provide iSCSI parameters to gPXE.
824 Enhance --dhcp-match to allow testing of the contents of a
825 client-sent option, as well as its presence. This
826 application in mind for this is RFC 4578
827 client-architecture specifiers, but it's generally useful.
828 Joey Korkames suggested the enhancement.
830 Move from using the IP_XMIT_IF ioctl to IP_BOUND_IF on
831 OpenSolaris. Thanks to Bastian Machek for the heads-up.
833 No longer complain about blank lines in
834 /etc/ethers. Thanks to Jon Nelson for the patch.
836 Fix binding of servers to physical devices, eg
837 --server=/domain/1.2.3.4@eth0 which was broken from 2.43
838 onwards unless --query-port=0 set. Thanks to Peter Naulls
841 Reply to DHCPINFORM requests even when the supplied ciaddr
842 doesn't fall in any dhcp-range. In this case it's not
843 possible to supply a complete configuration, but
844 individually-configured options (eg PAC) may be useful.
846 Allow the source address of an alias to be a range:
847 --alias=192.168.0.0,10.0.0.0,255.255.255.0 maps the whole
848 subnet 192.168.0.0->192.168.0.255 to 10.0.0.0->10.0.0.255,
850 --alias=192.168.0.10-192.168.0.40,10.0.0.0,255.255.255.0
851 maps only the 192.168.0.10->192.168.0.40 region. Thanks to
852 Ib Uhrskov for the suggestion.
854 Don't dynamically allocate DHCP addresses which may break
855 Windows. Addresses which end in .255 or .0 are broken in
856 Windows even when using supernetting.
857 --dhcp-range=192.168.0.1,192.168.1.254,255,255,254.0 means
858 192.168.0.255 is a valid IP address, but not for Windows.
859 See Microsoft KB281579. We therefore no longer allocate
860 these addresses to avoid hard-to-diagnose problems.
862 Update Polish translation. Thanks to Jan Psota.
864 Delete the PID-file when dnsmasq shuts down. Note that by
865 this time, dnsmasq is normally not running as root, so
866 this will fail if the PID-file is stored in a root-owned
867 directory; such failure is silently ignored. To take
868 advantage of this feature, the PID-file must be stored in a
869 directory owned and write-able by the user running
874 Allow --bootp-dynamic to take a netid tag, so that it may
875 be selectively enabled. Thanks to Olaf Westrik for the
878 Remove ISC-leasefile reading code. This has been
879 deprecated for a long time, and last time I removed it, it
880 ended up going back by request of one user. This time,
881 it's gone for good; otherwise it would need to be
882 re-worked to support multiple domains (see below).
884 Support DHCP clients in multiple DNS domains. This is a
885 long-standing request. Clients are assigned to a domain
886 based in their IP address.
888 Add --dhcp-fqdn flag, which changes behaviour if DNS names
889 assigned to DHCP clients. When this is set, there must be
890 a domain associated with each client, and only
891 fully-qualified domain names are added to the DNS. The
892 advantage is that the only the FQDN needs to be unique,
893 so that two or more DHCP clients can share a hostname, as
894 long as they are in different domains.
896 Set environment variable DNSMASQ_DOMAIN when invoking
897 lease-change script. This may be useful information to
898 have now that it's variable.
900 Tighten up data-checking code for DNS packet
901 handling. Thanks to Steve Dodd who found certain illegal
902 packets which could crash dnsmasq. No memory overwrite was
903 possible, so this is not a security issue beyond the DoS
906 Update example config dhcp option 47, the previous
907 suggestion generated an illegal, zero-length,
908 option. Thanks to Matthias Andree for finding this.
910 Rewrite hosts-file reading code to remove the limit of
911 1024 characters per line. John C Meuser found this.
913 Create a net-id tag with the name of the interface on
914 which the DHCP request was received.
916 Fixed minor memory leak in DBus code, thanks to Jeremy
919 Emit DBus signals as the DHCP lease database
920 changes. Thanks to Jeremy Laine for the patch.
922 Allow for more that one MAC address in a dhcp-host
923 line. This configuration tells dnsmasq that it's OK to
924 abandon a DHCP lease of the fixed address to one MAC
925 address, if another MAC address in the dhcp-host statement
926 asks for an address. This is useful to give a fixed
927 address to a host which has two network interfaces
928 (say, a laptop with wired and wireless interfaces.)
929 It's very important to ensure that only one interface
930 at a time is up, since dnsmasq abandons the first lease
931 and re-uses the address before the leased time has
932 elapsed. John Gray suggested this.
934 Tweak the response to a DHCP request packet with a wrong
935 server-id when --dhcp-authoritative is set; dnsmasq now
936 returns a DHCPNAK, rather than silently ignoring the
937 packet. Thanks to Chris Marget for spotting this
940 Add --cname option. This provides a limited alias
941 function, usable for DHCP names. Thanks to AJ Weber for
944 Updated contrib/webmin with latest version from Neil
947 Updated Polish translation. Thanks to Jan Psota.
949 Correct the text names for DHCP options 64 and 65 to be
950 "nis+-domain" and "nis+-servers".
952 Updated Spanish translation. Thanks to Chris Chatham.
954 Force re-reading of /etc/resolv.conf when an "interface
959 Fix total DNS failure in release 2.44 unless --min-port
960 specified. Thanks to Steven Barth and Grant Coady for
961 bugreport. Also reject out-of-range port spec, which could
962 break things too: suggestion from Gilles Espinasse.
966 Fix crash when unknown client attempts to renew a DHCP
967 lease, problem introduced in version 2.43. Thanks to
968 Carlos Carvalho for help chasing this down.
970 Fix potential crash when a host which doesn't have a lease
971 does DHCPINFORM. Again introduced in 2.43. This bug has
972 never been reported in the wild.
974 Fix crash in netlink code introduced in 2.43. Thanks to
975 Jean Wolter for finding this.
977 Change implementation of min_port to work even if min-port
980 Patch to enable compilation of latest Mac OS X. Thanks to
983 Update Spanish translation. Thanks to Christopher Chatham.
987 Updated Polish translation. Thanks to Jan Psota.
989 Flag errors when configuration options are repeated
992 Further tweaks for GNU/kFreeBSD
994 Add --no-wrap to msgmerge call - provides nicer .po file
997 Honour lease-time spec in dhcp-host lines even for
998 BOOTP. The user is assumed to known what they are doing in
999 this case. (Hosts without the time spec still get infinite
1000 leases for BOOTP, over-riding the default in the
1001 dhcp-range.) Thanks to Peter Katzmann for uncovering this.
1003 Fix problem matching relay-agent ids. Thanks to Michael
1004 Rack for the bug report.
1006 Add --naptr-record option. Suggestion from Johan
1009 Implement RFC 5107 server-id-override DHCP relay agent
1012 Apply patches from Stefan Kruger for compilation on
1013 Solaris 10 under Sun studio.
1015 Yet more tweaking of Linux capability code, to suppress
1016 pointless wingeing from kernel 2.6.25 and above.
1018 Improve error checking during startup. Previously, some
1019 errors which occurred during startup would be worked
1020 around, with dnsmasq still starting up. Some were logged,
1021 some silent. Now, they all cause a fatal error and dnsmasq
1022 terminates with a non-zero exit code. The errors are those
1023 associated with changing uid and gid, setting process
1024 capabilities and writing the pidfile. Thanks to Uwe
1025 Gansert and the Suse security team for pointing out
1026 this improvement, and Bill Reimers for good implementation
1029 Provide NO_LARGEFILE compile option to switch off largefile
1030 support when compiling against versions of uclibc which
1031 don't support it. Thanks to Stephane Billiart for the patch.
1033 Implement random source ports for interactions with
1034 upstream nameservers. New spoofing attacks have been found
1035 against nameservers which do not do this, though it is not
1036 clear if dnsmasq is vulnerable, since to doesn't implement
1037 recursion. By default dnsmasq will now use a different
1038 source port (and socket) for each query it sends
1039 upstream. This behaviour can suppressed using the
1040 --query-port option, and the old default behaviour
1041 restored using --query-port=0. Explicit source-port
1042 specifications in --server configs are still honoured.
1044 Replace the random number generator, for better
1045 security. On most BSD systems, dnsmasq uses the
1046 arc4random() RNG, which is secure, but on other platforms,
1047 it relied on the C-library RNG, which may be
1048 guessable and therefore allow spoofing. This release
1049 replaces the libc RNG with the SURF RNG, from Daniel
1050 J. Berstein's DJBDNS package.
1052 Don't attempt to change user or group or set capabilities
1053 if dnsmasq is run as a non-root user. Without this, the
1054 change from soft to hard errors when these fail causes
1055 problems for non-root daemons listening on high
1056 ports. Thanks to Patrick McLean for spotting this.
1058 Updated French translation. Thanks to Gildas Le Nadan.
1062 The changelog for version 2.42 and earlier is
1063 available in CHANGELOG.archive.
