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.
10 Add --dhcp-duid to allow DUID-EN uids to be used.
12 Explicity send DHCPv6 replies to the correct port, instead
13 of relying on clients to send requests with the correct
14 source address, since at least one client in the wild gets
15 this wrong. Thanks to Conrda Kostecki for help tracking
18 Send a preference value of 255 in DHCPv6 replies when
19 --dhcp-authoritative is in effect. This tells clients not
20 to wait around for other DHCP servers.
22 Better logging of DHCPv6 options.
26 Fix compilation problem in Mac OS X Lion. Thanks to Olaf
29 Fix DHCP when using --listen-address with an IP address
30 which is not the primary address of an interface.
32 Add --dhcp-client-update option.
34 Add Lua integration. Dnsmasq can now execute a DHCP
35 lease-change script written in Lua. This needs to be
36 enabled at compile time by setting HAVE_LUASCRIPT in
37 src/config.h or running "make COPTS=-DHAVE_LUASCRIPT"
38 Thanks to Jan-Piet Mens for the idea and proof-of-concept
41 Tidied src/config.h to distinguish between
42 platform-dependent compile-time options which are selected
43 automatically, and builder-selectable compile time
44 options. Document the latter better, and describe how to
45 set them from the make command line.
47 Tidied up IPPROTO_IP/SOL_IP (and IPv6 equivalent)
48 confusion. IPPROTO_IP works everywhere now.
50 Set TOS on DHCP sockets, this improves things on busy
51 wireless networks. Thanks to Dave Taht for the patch.
53 Determine VERSION automatically based on git magic:
54 release tags or hash values.
56 Improve start-up speed when reading large hosts files
57 containing many distinct addresses.
59 Fix problem if dnsmasq is started without the stdin,
60 stdout and stderr file descriptors open. This can manifest
61 itself as 100% CPU use. Thanks to Chris Moore for finding
64 Fix shell-scripting bug in bld/pkg-wrapper. Thanks to
65 Mark Mitchell for the patch.
67 Allow the TFP server or boot server in --pxe-service, to
68 be a domain name instead of an IP address. This allows for
69 round-robin to multiple servers, in the same way as
70 --dhcp-boot. A good suggestion from Cristiano Cumer.
72 Support BUILDDIR variable in the Makefile. Allows builds
73 for multiple archs from the same source tree with eg.
74 make BUILDDIR=linux (relative to dnsmasq tree)
75 make BUILDDIR=/tmp/openbsd (absolute path)
76 If BUILDDIR is not set, compilation happens in the src
77 directory, as before. Suggestion from Mark Mitchell.
79 Support DHCPv6. Support is there for the sort of things
80 the existing v4 server does, including tags, options,
81 static addresses and relay support. Missing is prefix
82 delegation, which is probably not required in the dnsmasq
83 niche, and an easy way to accept prefix delegations from
84 an upstream DHCPv6 server, which is. Future plans include
85 support for DHCPv6 router option and MAC address option
86 (to make selecting clients by MAC address work like IPv4).
87 These will be added as the standards mature.
88 This code has been tested, but this is the first release,
89 so don't bet the farm on it just yet. Many thanks to all
90 testers who have got it this far.
92 Support IPv6 router advertisements. This is a
93 simple-minded implementation, aimed at providing the
94 vestigial RA needed to go alongside IPv6. Is picks up
95 configuration from the DHCPv6 conf, and should just need
96 enabling with --enable-ra.
98 Fix long-standing wrinkle with --localise-queries that
99 could result in wrong answers when DNS packets arrive
100 via an interface other than the expected one. Thanks to
101 Lorenzo Milesi and John Hanks for spotting this one.
103 Update French translation. Thanks to Gildas Le Nadan.
105 Update Polish translation. Thanks to Jan Psota.
109 Fix regression in 2.58 which caused failure to start up
110 with some combinations of dnsmasq config and IPv6 kernel
111 network config. Thanks to Brielle Bruns for the bug
114 Improve dnsmasq's behaviour when network interfaces are
115 still doing duplicate address detection (DAD). Previously,
116 dnsmasq would wait up to 20 seconds at start-up for the
117 DAD state to terminate. This is broken for bridge
118 interfaces on recent Linux kernels, which don't start DAD
119 until the bridge comes up, and so can take arbitrary
120 time. The new behaviour lets dnsmasq poll for an arbitrary
121 time whilst providing service on other interfaces. Thanks
122 to Stephen Hemminger for pointing out the problem.
126 Provide a definition of the SA_SIZE macro where it's
127 missing. Fixes build failure on openBSD.
129 Don't include a zero terminator at the end of messages
130 sent to /dev/log when /dev/log is a datagram socket.
131 Thanks to Didier Rabound for spotting the problem.
133 Add --dhcp-sequential-ip flag, to force allocation of IP
134 addresses in ascending order. Note that the default
135 pseudo-random mode is in general better but some
136 server-deployment applications need this.
138 Fix problem where a server-id of 0.0.0.0 is sent to a
139 client when a dhcp-relay is in use if a client renews a
140 lease after dnsmasq restart and before any clients on the
141 subnet get a new lease. Thanks to Mike Ruiz for assistance
142 in chasing this one down.
144 Don't return NXDOMAIN to an AAAA query if we have CNAME
145 which points to an A record only: NODATA is the correct
146 reply in this case. Thanks to Tom Fernandes for spotting
149 Relax the need to supply a netmask in --dhcp-range for
150 networks which use a DHCP relay. Whilst this is still
151 desireable, in the absence of a netmask dnsmasq will use
152 a default based on the class (A, B, or C) of the address.
153 This should at least remove a cause of mysterious failure
154 for people using RFC1918 addresses and relays.
156 Add support for Linux conntrack connection marking. If
157 enabled with --conntrack, the connection mark for incoming
158 DNS queries will be copied to the outgoing connections
159 used to answer those queries. This allows clever firewall
160 and accounting stuff. Only available if dnsmasq is
161 compiled with HAVE_CONNTRACK and adds a dependency on
162 libnetfilter-conntrack. Thanks to Ed Wildgoose for the
163 initial idea, testing and sponsorship of this function.
165 Provide a sane error message when someone attempts to
166 match a tag in --dhcp-host.
168 Tweak the behaviour of --domain-needed, to avoid problems
169 with recursive nameservers downstream of dnsmasq. The new
170 behaviour only stops A and AAAA queries, and returns
171 NODATA rather than NXDOMAIN replies.
173 Efficiency fix for very large DHCP configurations, thanks
174 to James Gartrell and Mike Ruiz for help with this.
176 Allow the TFTP-server address in --dhcp-boot to be a
177 domain-name which is looked up in /etc/hosts. This can
178 give multiple IP addresses which are used round-robin,
179 thus doing TFTP server load-balancing. Thanks to Sushil
180 Agrawal for the patch.
182 When two tagged dhcp-options for a particular option
183 number are both valid, use the one which is valid without
184 a tag from the dhcp-range. Allows overriding of the value
185 of a DHCP option for a particular host as well as
186 per-network values. So
187 --dhcp-range=set:interface1,......
188 --dhcp-host=set:myhost,.....
189 --dhcp-option=tag:interface1,option:nis-domain,"domain1"
190 --dhcp-option=tag:myhost,option:nis-domain,"domain2"
191 will set the NIS-domain to domain1 for hosts in the range, but
192 override that to domain2 for a particular host.
194 Fix bug which resulted in truncated files and timeouts for
195 some TFTP transfers. The bug only occurs with netascii
196 transfers and needs an unfortunate relationship between
197 file size, blocksize and the number of newlines in the
198 last block before it manifests itself. Many thanks to
199 Alkis Georgopoulos for spotting the problem and providing
200 a comprehensive test-case.
202 Fix regression in TFTP server on *BSD platforms introduced
203 in version 2.56, due to confusion with sockaddr
204 length. Many thanks to Loïc Pefferkorn for finding this.
206 Support scope-ids in IPv6 addresses of nameservers from
207 /etc/resolv.conf and in --server options. Eg
208 nameserver fe80::202:a412:4512:7bbf%eth0 or
209 server=fe80::202:a412:4512:7bbf%eth0. Thanks to
210 Michael Stapelberg for the suggestion.
212 Update Polish translation, thanks to Jan Psota.
214 Update French translation. Thanks to Gildas Le Nadan.
218 Add patches to allow build under Android.
220 Provide our own header for the DNS protocol, rather than
221 relying on arpa/nameser.h. This has proved more or less
222 defective over the years and the final straw is that it's
223 effectively empty on Android.
225 Fix regression in 2.56 which caused hex constants in
226 configuration to be rejected if they contain the '*'
229 Correct wrong casts of arguments to ctype.h functions,
230 isdigit(), isxdigit() etc. Thanks to Matthias Andree for
233 Allow build with IDN support independently from i18n.
234 IDN support continues to be included automatically
235 when i18n is included.
236 'make COPTS=-DHAVE_IDN' is the magic incantation.
238 Modify check on extraneous command line junk (added in
239 2.56) so that it doesn't complain about extra _empty_
240 arguments. Otherwise this breaks libvirt.
244 Add a patch to allow dnsmasq to get interface names right in a
245 Solaris zone. Thanks to Dj Padzensky for this.
247 Improve data-type parsing heuristics so that
248 --dhcp-option=option:domain-search,.
249 treats the value as a string and not an IP address.
250 Thanks to Clemens Fischer for spotting that.
252 Add IPv6 support to the TFTP server. Many thanks to Jan
253 'RedBully' Seiffert for the patches.
255 Log DNS queries at level LOG_INFO, rather then
256 LOG_DEBUG. This makes things consistent with DHCP
257 logging. Thanks to Adam Pribyl for spotting the problem.
259 Ensure that dnsmasq terminates cleanly when using
260 --syslog-async even if it cannot make a connection to the
263 Add --add-mac option. This is to support currently
264 experimental DNS filtering facilities. Thanks to Benjamin
265 Petrin for the orignal patch.
267 Fix bug which meant that tags were ignored in dhcp-range
268 configuration specifying PXE-proxy service. Thanks to
269 Cristiano Cumer for spotting this.
271 Raise an error if there is extra junk, not part of an
272 option, on the command line.
274 Flag a couple of log messages in cache.c as coming from
275 the DHCP subsystem. Thanks to Olaf Westrik for the patch.
277 Omit timestamps from logs when a) logging to stderr and
278 b) --keep-in-forground is set. The logging facility on the
279 other end of stderr can be assumned to supply them. Thanks
280 to John Hallam for the patch.
282 Don't complain about strings longer than 255 characters in
283 --txt-record, just split the long strings into 255
284 character chunks instead.
286 Fix crash on double-free. This bug can only happen when
287 dhcp-script is in use and then only in rare circumstances
288 triggered by high DHCP transaction rate and a slow
289 script. Thanks to Ferenc Wagner for finding the problem.
291 Only log that a file has been sent by TFTP after the
292 transfer has completed succesfully.
294 A good suggestion from Ferenc Wagner: extend
295 the --domain option to allow this sort of thing:
296 --domain=thekelleys.org.uk,192.168.0.0/24,local
297 which automatically creates
298 --local=/thekelleys.org.uk/
299 --local=/0.168.192.in-addr.arpa/
301 Tighten up syntax checking of hex contants in the config
302 file. Thanks to Fred Damen for spotting this.
304 Add dnsmasq logo/icon, contributed by Justin Swift. Many
307 Never cache DNS replies which have the 'cd' bit set, or
308 which result from queries forwarded with the 'cd' bit
309 set. The 'cd' bit instructs a DNSSEC validating server
310 upstream to ignore signature failures and return replies
311 anyway. Without this change it's possible to pollute the
312 dnsmasq cache with bad data by making a query with the
313 'cd' bit set and subsequent queries would return this data
314 without its being marked as suspect. Thanks to Anders
315 Kaseorg for pointing out this problem.
317 Add --proxy-dnssec flag, for compliance with RFC
318 4035. Dnsmasq will now clear the 'ad' bit in answers returned
319 from upstream validating nameservers unless this option is
322 Allow a filename of "-" for --conf-file to read
323 stdin. Suggestion from Timothy Redaelli.
325 Rotate the order of SRV records in replies, to provide
326 round-robin load balancing when all the priorities are
327 equal. Thanks to Peter McKinney for the suggestion.
330 contrib/MacOSX-launchd/uk.org.thekelleys.dnsmasq.plist
331 so that it doesn't log all queries to a file by
332 default. Thanks again to Peter McKinney.
334 By default, setting an IPv4 address for a domain but not
335 an IPv6 address causes dnsmasq to return
336 an NODATA reply for IPv6 (or vice-versa). So
337 --address=/google.com/1.2.3.4 stops IPv6 queries for
338 *google.com from being forwarded. Make it possible to
339 override this behaviour by defining the sematics if the
340 same domain appears in both --server and --address.
341 In that case, the --address has priority for the address
342 family in which is appears, but the --server has priority
343 of the address family which doesn't appear in --adddress
345 --address=/google.com/1.2.3.4
346 --server=/google.com/#
347 will return 1.2.3.4 for IPv4 queries for *.google.com but
348 forward IPv6 queries to the normal upstream nameserver.
349 Similarly when setting an IPv6 address
350 only this will allow forwarding of IPv4 queries. Thanks to
351 William for pointing out the need for this.
353 Allow more than one --dhcp-optsfile and --dhcp-hostsfile
354 and make them understand directories as arguments in the
355 same way as --addn-hosts. Suggestion from John Hanks.
357 Ignore rebinding requests for leases we don't know
358 about. Rebind is broadcast, so we might get to overhear a
359 request meant for another DHCP server. NAKing this is
360 wrong. Thanks to Brad D'Hondt for assistance with this.
362 Fix cosmetic bug which produced strange output when
363 dumping cache statistics with some configurations. Thanks
364 to Fedor Kozhevnikov for spotting this.
368 Fix crash when /etc/ethers is in use. Thanks to
369 Gianluigi Tiesi for finding this.
371 Fix crash in netlink_multicast(). Thanks to Arno Wald for
374 Allow the empty domain "." in dhcp domain-search (119)
379 There is no version 2.54 to avoid confusion with 2.53,
380 which incorrectly identifies itself as 2.54.
384 Fix failure to compile on Debian/kFreeBSD. Thanks to
385 Axel Beckert and Petr Salinger.
387 Fix code to avoid scary strict-aliasing warnings
388 generated by gcc 4.4.
390 Added FAQ entry warning about DHCP failures with Vista
391 when firewalls block 255.255.255.255.
393 Fixed bug which caused bad things to happen if a
394 resolv.conf file which exists is subsequently removed.
395 Thanks to Nikolai Saoukh for the patch.
397 Rationalised the DHCP tag system. Every configuration item
398 which can set a tag does so by adding "set:<tag>" and
399 every configuration item which is conditional on a tag is
400 made so by "tag:<tag>". The NOT operator changes to '!',
401 which is a bit more intuitive too. Dhcp-host directives
402 can set more than one tag now. The old '#' NOT,
403 "net:" prefix and no-prefixes are still honoured, so
404 no existing config file needs to be changed, but
405 the documentation and new-style config files should be
408 Added --tag-if to allow boolean operations on tags.
409 This allows complicated logic to be clearer and more
410 general. A great suggestion from Richard Voigt.
412 Add broadcast/unicast information to DHCP logging.
414 Allow --dhcp-broadcast to be unconditional.
416 Fixed incorrect behaviour with NOT <tag> conditionals in
417 dhcp-options. Thanks to Max Turkewitz for assistance
420 If we send vendor-class encapsulated options based on the
421 vendor-class supplied by the client, and no explicit
422 vendor-class option is given, echo back the vendor-class
425 Fix bug which stopped dnsmasq from matching both a
426 circuitid and a remoteid. Thanks to Ignacio Bravo for
429 Add --dhcp-proxy, which makes it possible to configure
430 dnsmasq to use a DHCP relay agent as a full proxy, with
431 all DHCP messages passing through the proxy. This is
432 useful if the relay adds extra information to the packets
433 it forwards, but cannot be configured with the RFC 5107
434 server-override option.
436 Added interface:<iface name> part to dhcp-range. The
437 semantics of this are very odd at first sight, but it
438 allows a single line of the form
439 dhcp-range=interface:virt0,192.168.0.4,192.168.0.200
440 to be added to dnsmasq configuration which then supplies
441 DHCP and DNS services to that interface, without affecting
442 what services are supplied to other interfaces and
443 irrespective of the existance or lack of
444 interface=<interface>
445 lines elsewhere in the dnsmasq configuration. The idea is
446 that such a line can be added automatically by libvirt
447 or equivalent systems, without disturbing any manual
450 Similarly to the above, allow --enable-tftp=<interface>
452 Allow a TFTP root to be set separately for requests via
453 different interfaces, --tftp-root=<path>,<interface>
455 Correctly handle and log clashes between CNAMES and
456 DNS names being given to DHCP leases. This fixes a bug
457 which caused nonsense IP addresses to be logged. Thanks to
458 Sergei Zhirikov for finding and analysing the problem.
460 Tweak flush_log so as to avoid leaving the log
461 file in non-blocking mode. O_NONBLOCK is a property of the
462 file, not the process/descriptor.
464 Fix contrib/Solaris10/create_package
465 (/usr/man -> /usr/share/man) Thanks to Vita Batrla.
467 Fix a problem where, if a client got a lease, then went
468 to another subnet and got another lease, then moved back,
469 it couldn't resume the old lease, but would instead get
470 a new address. Thanks to Leonardo Rodrigues for spotting
471 this and testing the fix.
473 Fix weird bug which sometimes omitted certain characters
474 from the start of quoted strings in dhcp-options. Thanks
475 to Dayton Turner for spotting the problem.
477 Add facility to redirect some domains to the standard
478 upstream servers: this allows something like
479 --server=/google.com/1.2.3.4 --server=/www.google.com/#
480 which will send queries for *.google.com to 1.2.3.4,
481 except *www.google.com which will be forwarded as usual.
482 Thanks to AJ Weber for prompting this addition.
484 Improve the hash-algorithm used to generate IP addresses
485 from MAC addresses during initial DHCP address
486 allocation. This improves performance when large numbers
487 of hosts with similar MAC addresses all try and get an IP
488 address at the same time. Thanks to Paul Smith for his
491 Tweak DHCP code so that --bridge-interface can be used to
492 select which IP alias of an interface should be used for
493 DHCP purposes on Linux. If eth0 has an alias eth0:dhcp
494 then adding --bridge-interface=eth0:dhcp,eth0 will use
495 the address of eth0:dhcp to determine the correct subnet
496 for DHCP address allocation. Thanks to Pawel Golaszewski
497 for prompting this and Eric Cooper for further testing.
499 Add --dhcp-generate-names. Suggestion by Ferenc Wagner.
501 Tweak DNS server selection algorithm when there is more
502 than one server available for a domain, eg.
503 --server=/mydomain/1.1.1.1
504 --server=/mydomain/2.2.2.2
505 Thanks to Alberto Cuesta-Canada for spotting a weakness
508 Add --max-ttl. Thanks to Fredrik Ringertz for the patch.
510 Allow --log-facility=- to force all logging to
511 stderr. Suggestion from Clemens Fischer.
513 Fix regression which caused configuration like
514 --address=/.domain.com/1.2.3.4 to be rejected. The dot to the
515 left of the domain has been implied and not required for a
516 long time, but it should be accepted for backward
517 compatibility. Thanks to Andrew Burcin for spotting this.
519 Add --rebind-domain-ok and --rebind-localhost-ok.
520 Suggestion from Clemens Fischer.
522 Log replies to queries of type TXT, when --log-queries
525 Fix compiler warnings when compiled with -DNO_DHCP. Thanks
526 to Shantanu Gadgil for the patch.
528 Updated French translation. Thanks to Gildas Le Nadan.
530 Updated Polish translation. Thanks to Jan Psota.
532 Updated German translation. Thanks to Matthias Andree.
534 Added contrib/static-arp, thanks to Darren Hoo.
536 Fix corruption of the domain when a name from /etc/hosts
537 overrides one supplied by a DHCP client. Thanks to Fedor
538 Kozhevnikov for spotting the problem.
540 Updated Spanish translation. Thanks to Chris Chatham.
544 Work around a Linux kernel bug which insists that the
545 length of the option passed to setsockopt must be at least
546 sizeof(int) bytes, even if we're calling SO_BINDTODEVICE
547 and the device name is "lo". Note that this is fixed
548 in kernel 2.6.31, but the workaround is harmless and
549 allows earlier kernels to be used. Also fix dnsmasq
550 bug which reported the wrong address when this failed.
551 Thanks to Fedor for finding this.
553 The API for IPv6 PKTINFO changed around Linux kernel
554 2.6.14. Workaround the case where dnsmasq is compiled
555 against newer headers, but then run on an old kernel:
556 necessary for some *WRT distros.
558 Re-read the set of network interfaces when re-loading
559 /etc/resolv.conf if --bind-interfaces is not set. This
560 handles the case that loopback interfaces do not exist
561 when dnsmasq is first started.
563 Tweak the PXE code to support port 4011. This should
564 reduce broadcasts and make things more reliable when other
565 servers are around. It also improves inter-operability
566 with certain clients.
568 Make a pxe-service configuration with no filename or boot
569 service type legal: this does a local boot. eg.
570 pxe-service=x86PC, "Local boot"
572 Be more conservative in detecting "A for A"
573 queries. Dnsmasq checks if the name in a type=A query looks
574 like a dotted-quad IP address and answers the query itself
575 if so, rather than forwarding it. Previously dnsmasq
576 relied in the library function inet_addr() to convert
577 addresses, and that will accept some things which are
578 confusing in this context, like 1.2.3 or even just
579 1234. Now we only do A for A processing for four decimal
580 numbers delimited by dots.
582 A couple of tweaks to fix compilation on Solaris. Thanks
583 to Joel Macklow for help with this.
585 Another Solaris compilation tweak, needed for Solaris
586 2009.06. Thanks to Lee Essen for that.
588 Added extract packaging stuff from Lee Essen to
591 Increased the default limit on number of leases to 1000
592 (from 150). This is mainly a defence against DoS attacks,
593 and for the average "one for two class C networks"
594 installation, IP address exhaustion does that just as
595 well. Making the limit greater than the number of IP
596 addresses available in such an installation removes a
597 surprise which otherwise can catch people out.
599 Removed extraneous trailing space in the value of the
600 DNSMASQ_TIME_REMAINING DNSMASQ_LEASE_LENGTH and
601 DNSMASQ_LEASE_EXPIRES environment variables. Thanks to
602 Gildas Le Nadan for spotting this.
604 Provide the network-id tags for a DHCP transaction to
605 the lease-change script in the environment variable
606 DNSMASQ_TAGS. A good suggestion from Gildas Le Nadan.
608 Add support for RFC3925 "Vendor-Identifying Vendor
609 Options". The syntax looks like this:
610 --dhcp-option=vi-encap:<enterprise number>, .........
612 Add support to --dhcp-match to allow matching against
613 RFC3925 "Vendor-Identifying Vendor Classes". The syntax
615 --dhcp-match=tag,vi-encap<enterprise number>, <value>
617 Add some application specific code to assist in
618 implementing the Broadband forum TR069 CPE-WAN
619 specification. The details are in contrib/CPE-WAN/README
621 Increase the default DNS packet size limit to 4096, as
622 recommended by RFC5625 section 4.4.3. This can be
623 reconfigured using --edns-packet-max if needed. Thanks to
624 Francis Dupont for pointing this out.
626 Rewrite query-ids even for TSIG signed packets, since
627 this is allowed by RFC5625 section 4.5.
629 Use getopt_long by default on OS X. It has been supported
630 since version 10.3.0. Thanks to Arek Dreyer for spotting
633 Added up-to-date startup configuration for MacOSX/launchd
634 in contrib/MacOSX-launchd. Thanks to Arek Dreyer for
637 Fix link error when including Dbus but excluding DHCP.
638 Thanks to Oschtan for the bug report.
640 Updated French translation. Thanks to Gildas Le Nadan.
642 Updated Polish translation. Thanks to Jan Psota.
644 Updated Spanish translation. Thanks to Chris Chatham.
646 Fixed confusion about domains, when looking up DHCP hosts
647 in /etc/hosts. This could cause spurious "Ignoring
648 domain..." messages. Thanks to Fedor Kozhevnikov for
649 finding and analysing the problem.
653 Add support for internationalised DNS. Non-ASCII characters
654 in domain names found in /etc/hosts, /etc/ethers and
655 /etc/dnsmasq.conf will be correctly handled by translation to
656 punycode, as specified in RFC3490. This function is only
657 available if dnsmasq is compiled with internationalisation
658 support, and adds a dependency on GNU libidn. Without i18n
659 support, dnsmasq continues to be compilable with just
660 standard tools. Thanks to Yves Dorfsman for the
663 Add two more environment variables for lease-change scripts:
664 First, DNSMASQ_SUPPLIED_HOSTNAME; this is set to the hostname
665 supplied by a client, even if the actual hostname used is
666 over-ridden by dhcp-host or dhcp-ignore-names directives.
667 Also DNSMASQ_RELAY_ADDRESS which gives the address of
668 a DHCP relay, if used.
669 Suggestions from Michael Rack.
671 Fix regression which broke echo of relay-agent
672 options. Thanks to Michael Rack for spotting this.
674 Don't treat option 67 as being interchangeable with
675 dhcp-boot parameters if it's specified as
678 Make the code to call scripts on lease-change compile-time
679 optional. It can be switched off by editing src/config.h
680 or building with "make COPTS=-DNO_SCRIPT".
682 Make the TFTP server cope with filenames from Windows/DOS
683 which use '\' as pathname separator. Thanks to Ralf for
686 Updated Polish translation. Thanks to Jan Psota.
688 Warn if an IP address is duplicated in /etc/ethers. Thanks
689 to Felix Schwarz for pointing this out.
691 Teach --conf-dir to take an option list of file suffices
692 which will be ignored when scanning the directory. Useful
693 for backup files etc. Thanks to Helmut Hullen for the
696 Add new DHCP option named tftpserver-address, which
697 corresponds to the third argument of dhcp-boot. This
698 allows the complete functionality of dhcp-boot to be
699 replicated with dhcp-option. Useful when using
702 Test which upstream nameserver to use every 10 seconds
703 or 50 queries and not just when a query times out and
704 is retried. This should improve performance when there
705 is a slow nameserver in the list. Thanks to Joe for the
708 Don't do any PXE processing, even for clients with the
709 correct vendorclass, unless at least one pxe-prompt or
710 pxe-service option is given. This stops dnsmasq
711 interfering with proxy PXE subsystems when it is just
712 the DHCP server. Thanks to Spencer Clark for spotting this.
714 Limit the blocksize used for TFTP transfers to a value
715 which avoids packet fragmentation, based on the MTU of the
716 local interface. Many netboot ROMs can't cope with
719 Honour dhcp-ignore configuration for PXE and proxy-PXE
720 requests. Thanks to Niels Basjes for the bug report.
722 Updated French translation. Thanks to Gildas Le Nadan.
726 Fix security problem which allowed any host permitted to
727 do TFTP to possibly compromise dnsmasq by remote buffer
728 overflow when TFTP enabled. Thanks to Core Security
729 Technologies and Iván Arce, Pablo Hernán Jorge, Alejandro
730 Pablo Rodriguez, Martín Coco, Alberto Soliño Testa and
731 Pablo Annetta. This problem has Bugtraq id: 36121
734 Fix a problem which allowed a malicious TFTP client to
735 crash dnsmasq. Thanks to Steve Grubb at Red Hat for
736 spotting this. This problem has Bugtraq id: 36120 and
741 Fix regression in 2.48 which disables the lease-change
742 script. Thanks to Jose Luis Duran for spotting this.
744 Log TFTP "file not found" errors. These were not logged,
745 since a normal PXELinux boot generates many of them, but
746 the lack of the messages seems to be more confusing than
747 routinely seeing them when there is no real error.
749 Update Spanish translation. Thanks to Chris Chatham.
753 Archived the extensive, backwards, changelog to
754 CHANGELOG.archive. The current changelog now runs from
755 version 2.43 and runs conventionally.
757 Fixed bug which broke binding of servers to physical
758 interfaces when interface names were longer than four
759 characters. Thanks to MURASE Katsunori for the patch.
761 Fixed netlink code to check that messages come from the
762 correct source, and not another userspace process. Thanks
763 to Steve Grubb for the patch.
765 Maintainability drive: removed bug and missing feature
766 workarounds for some old platforms. Solaris 9, OpenBSD
767 older than 4.1, Glibc older than 2.2, Linux 2.2.x and
768 DBus older than 1.1.x are no longer supported.
770 Don't read included configuration files more than once:
771 allows complex configuration structures without problems.
773 Mark log messages from the various subsystems in dnsmasq:
774 messages from the DHCP subsystem now have the ident string
775 "dnsmasq-dhcp" and messages from TFTP have ident
776 "dnsmasq-tftp". Thanks to Olaf Westrik for the patch.
778 Fix possible infinite DHCP protocol loop when an IP
779 address nailed to a hostname (not a MAC address) and a
780 host sometimes provides the name, sometimes not.
782 Allow --addn-hosts to take a directory: all the files
783 in the directory are read. Thanks to Phil Cornelius for
786 Support --bridge-interface on all platforms, not just BSD.
788 Added support for advanced PXE functions. It's now
789 possible to define a prompt and menu options which will
790 be displayed when a client PXE boots. It's also possible to
791 hand-off booting to other boot servers. Proxy-DHCP, where
792 dnsmasq just supplies the PXE information and another DHCP
793 server does address allocation, is also allowed. See the
794 --pxe-prompt and --pxe-service keywords. Thanks to
795 Alkis Georgopoulos for the suggestion and Guilherme Moro
796 and Michael Brown for assistance.
798 Improvements to DHCP logging. Thanks to Tom Metro for
801 Add ability to build dnsmasq without DHCP support. To do
802 this, edit src/config.h or build with
803 "make COPTS=-DNO_DHCP". Thanks to Mahavir Jain for the patch.
805 Added --test command-line switch - syntax check
806 configuration files only.
808 Updated French translation. Thanks to Gildas Le Nadan.
812 Updated French translation. Thanks to Gildas Le Nadan.
814 Fixed interface enumeration code to work on NetBSD
815 5.0. Thanks to Roy Marples for the patch.
817 Updated config.h to use the same location for the lease
818 file on NetBSD as the other *BSD variants. Also allow
819 LEASEFILE and CONFFILE symbols to be overriden in CFLAGS.
821 Handle duplicate address detection on IPv6 more
822 intelligently. In IPv6, an interface can have an address
823 which is not usable, because it is still undergoing DAD
824 (such addresses are marked "tentative"). Attempting to
825 bind to an address in this state returns an error,
826 EADDRNOTAVAIL. Previously, on getting such an error,
827 dnsmasq would silently abandon the address, and never
828 listen on it. Now, it retries once per second for 20
829 seconds before generating a fatal error. 20 seconds should
830 be long enough for any DAD process to complete, but can be
831 adjusted in src/config.h if necessary. Thanks to Martin
832 Krafft for the bug report.
834 Add DBus introspection. Patch from Jeremy Laine.
836 Update Dbus configuration file. Patch from Colin Walters.
838 http://bugs.freedesktop.org/show_bug.cgi?id=18961
840 Support arbitrarily encapsulated DHCP options, suggestion
841 and initial patch from Samium Gromoff. This is useful for
842 (eg) gPXE, which expect all its private options to be
843 encapsulated inside a single option 175. So, eg,
845 dhcp-option = encap:175, 190, "iscsi-client0"
846 dhcp-option = encap:175, 191, "iscsi-client0-secret"
848 will provide iSCSI parameters to gPXE.
850 Enhance --dhcp-match to allow testing of the contents of a
851 client-sent option, as well as its presence. This
852 application in mind for this is RFC 4578
853 client-architecture specifiers, but it's generally useful.
854 Joey Korkames suggested the enhancement.
856 Move from using the IP_XMIT_IF ioctl to IP_BOUND_IF on
857 OpenSolaris. Thanks to Bastian Machek for the heads-up.
859 No longer complain about blank lines in
860 /etc/ethers. Thanks to Jon Nelson for the patch.
862 Fix binding of servers to physical devices, eg
863 --server=/domain/1.2.3.4@eth0 which was broken from 2.43
864 onwards unless --query-port=0 set. Thanks to Peter Naulls
867 Reply to DHCPINFORM requests even when the supplied ciaddr
868 doesn't fall in any dhcp-range. In this case it's not
869 possible to supply a complete configuration, but
870 individually-configured options (eg PAC) may be useful.
872 Allow the source address of an alias to be a range:
873 --alias=192.168.0.0,10.0.0.0,255.255.255.0 maps the whole
874 subnet 192.168.0.0->192.168.0.255 to 10.0.0.0->10.0.0.255,
876 --alias=192.168.0.10-192.168.0.40,10.0.0.0,255.255.255.0
877 maps only the 192.168.0.10->192.168.0.40 region. Thanks to
878 Ib Uhrskov for the suggestion.
880 Don't dynamically allocate DHCP addresses which may break
881 Windows. Addresses which end in .255 or .0 are broken in
882 Windows even when using supernetting.
883 --dhcp-range=192.168.0.1,192.168.1.254,255,255,254.0 means
884 192.168.0.255 is a valid IP address, but not for Windows.
885 See Microsoft KB281579. We therefore no longer allocate
886 these addresses to avoid hard-to-diagnose problems.
888 Update Polish translation. Thanks to Jan Psota.
890 Delete the PID-file when dnsmasq shuts down. Note that by
891 this time, dnsmasq is normally not running as root, so
892 this will fail if the PID-file is stored in a root-owned
893 directory; such failure is silently ignored. To take
894 advantage of this feature, the PID-file must be stored in a
895 directory owned and write-able by the user running
900 Allow --bootp-dynamic to take a netid tag, so that it may
901 be selectively enabled. Thanks to Olaf Westrik for the
904 Remove ISC-leasefile reading code. This has been
905 deprecated for a long time, and last time I removed it, it
906 ended up going back by request of one user. This time,
907 it's gone for good; otherwise it would need to be
908 re-worked to support multiple domains (see below).
910 Support DHCP clients in multiple DNS domains. This is a
911 long-standing request. Clients are assigned to a domain
912 based in their IP address.
914 Add --dhcp-fqdn flag, which changes behaviour if DNS names
915 assigned to DHCP clients. When this is set, there must be
916 a domain associated with each client, and only
917 fully-qualified domain names are added to the DNS. The
918 advantage is that the only the FQDN needs to be unique,
919 so that two or more DHCP clients can share a hostname, as
920 long as they are in different domains.
922 Set environment variable DNSMASQ_DOMAIN when invoking
923 lease-change script. This may be useful information to
924 have now that it's variable.
926 Tighten up data-checking code for DNS packet
927 handling. Thanks to Steve Dodd who found certain illegal
928 packets which could crash dnsmasq. No memory overwrite was
929 possible, so this is not a security issue beyond the DoS
932 Update example config dhcp option 47, the previous
933 suggestion generated an illegal, zero-length,
934 option. Thanks to Matthias Andree for finding this.
936 Rewrite hosts-file reading code to remove the limit of
937 1024 characters per line. John C Meuser found this.
939 Create a net-id tag with the name of the interface on
940 which the DHCP request was received.
942 Fixed minor memory leak in DBus code, thanks to Jeremy
945 Emit DBus signals as the DHCP lease database
946 changes. Thanks to Jeremy Laine for the patch.
948 Allow for more that one MAC address in a dhcp-host
949 line. This configuration tells dnsmasq that it's OK to
950 abandon a DHCP lease of the fixed address to one MAC
951 address, if another MAC address in the dhcp-host statement
952 asks for an address. This is useful to give a fixed
953 address to a host which has two network interfaces
954 (say, a laptop with wired and wireless interfaces.)
955 It's very important to ensure that only one interface
956 at a time is up, since dnsmasq abandons the first lease
957 and re-uses the address before the leased time has
958 elapsed. John Gray suggested this.
960 Tweak the response to a DHCP request packet with a wrong
961 server-id when --dhcp-authoritative is set; dnsmasq now
962 returns a DHCPNAK, rather than silently ignoring the
963 packet. Thanks to Chris Marget for spotting this
966 Add --cname option. This provides a limited alias
967 function, usable for DHCP names. Thanks to AJ Weber for
970 Updated contrib/webmin with latest version from Neil
973 Updated Polish translation. Thanks to Jan Psota.
975 Correct the text names for DHCP options 64 and 65 to be
976 "nis+-domain" and "nis+-servers".
978 Updated Spanish translation. Thanks to Chris Chatham.
980 Force re-reading of /etc/resolv.conf when an "interface
985 Fix total DNS failure in release 2.44 unless --min-port
986 specified. Thanks to Steven Barth and Grant Coady for
987 bugreport. Also reject out-of-range port spec, which could
988 break things too: suggestion from Gilles Espinasse.
992 Fix crash when unknown client attempts to renew a DHCP
993 lease, problem introduced in version 2.43. Thanks to
994 Carlos Carvalho for help chasing this down.
996 Fix potential crash when a host which doesn't have a lease
997 does DHCPINFORM. Again introduced in 2.43. This bug has
998 never been reported in the wild.
1000 Fix crash in netlink code introduced in 2.43. Thanks to
1001 Jean Wolter for finding this.
1003 Change implementation of min_port to work even if min-port
1006 Patch to enable compilation of latest Mac OS X. Thanks to
1009 Update Spanish translation. Thanks to Christopher Chatham.
1013 Updated Polish translation. Thanks to Jan Psota.
1015 Flag errors when configuration options are repeated
1018 Further tweaks for GNU/kFreeBSD
1020 Add --no-wrap to msgmerge call - provides nicer .po file
1023 Honour lease-time spec in dhcp-host lines even for
1024 BOOTP. The user is assumed to known what they are doing in
1025 this case. (Hosts without the time spec still get infinite
1026 leases for BOOTP, over-riding the default in the
1027 dhcp-range.) Thanks to Peter Katzmann for uncovering this.
1029 Fix problem matching relay-agent ids. Thanks to Michael
1030 Rack for the bug report.
1032 Add --naptr-record option. Suggestion from Johan
1035 Implement RFC 5107 server-id-override DHCP relay agent
1038 Apply patches from Stefan Kruger for compilation on
1039 Solaris 10 under Sun studio.
1041 Yet more tweaking of Linux capability code, to suppress
1042 pointless wingeing from kernel 2.6.25 and above.
1044 Improve error checking during startup. Previously, some
1045 errors which occurred during startup would be worked
1046 around, with dnsmasq still starting up. Some were logged,
1047 some silent. Now, they all cause a fatal error and dnsmasq
1048 terminates with a non-zero exit code. The errors are those
1049 associated with changing uid and gid, setting process
1050 capabilities and writing the pidfile. Thanks to Uwe
1051 Gansert and the Suse security team for pointing out
1052 this improvement, and Bill Reimers for good implementation
1055 Provide NO_LARGEFILE compile option to switch off largefile
1056 support when compiling against versions of uclibc which
1057 don't support it. Thanks to Stephane Billiart for the patch.
1059 Implement random source ports for interactions with
1060 upstream nameservers. New spoofing attacks have been found
1061 against nameservers which do not do this, though it is not
1062 clear if dnsmasq is vulnerable, since to doesn't implement
1063 recursion. By default dnsmasq will now use a different
1064 source port (and socket) for each query it sends
1065 upstream. This behaviour can suppressed using the
1066 --query-port option, and the old default behaviour
1067 restored using --query-port=0. Explicit source-port
1068 specifications in --server configs are still honoured.
1070 Replace the random number generator, for better
1071 security. On most BSD systems, dnsmasq uses the
1072 arc4random() RNG, which is secure, but on other platforms,
1073 it relied on the C-library RNG, which may be
1074 guessable and therefore allow spoofing. This release
1075 replaces the libc RNG with the SURF RNG, from Daniel
1076 J. Berstein's DJBDNS package.
1078 Don't attempt to change user or group or set capabilities
1079 if dnsmasq is run as a non-root user. Without this, the
1080 change from soft to hard errors when these fail causes
1081 problems for non-root daemons listening on high
1082 ports. Thanks to Patrick McLean for spotting this.
1084 Updated French translation. Thanks to Gildas Le Nadan.
1088 The changelog for version 2.42 and earlier is
1089 available in CHANGELOG.archive.
