Annotation of embedaddon/dnsmasq/CHANGELOG.archive, revision 1.1.1.2
1.1 misho 1: release 0.4 - initial public release
2:
3: release 0.5 - added caching, removed compiler warning on linux PPC
4:
5: release 0.6 - TCP handling: close socket and return to connect state if we
6: can't read the first byte. This corrects a problem seen very
7: occasionally where dnsmasq would loop using all available CPU.
8:
9: Added a patch from Cris Bailiff <c.bailiff@e-secure.com.au>
10: to set SO_REUSEADDR on the tcp socket which stops problems when
11: dnsmasq is restarted and old connections still exist.
12:
13: Stopped claiming in doc.html that smail is the default Debian
14: mailer, since it isn't any longer. (Pointed out by
15: David Karlin <dkarlin@coloradomtn.edu>)
16:
17: release 0.7 Create a pidfile at /var/run/dnsmasq.pid
18:
19: Extensive armouring against "poison packets" courtesy of
20: Thomas Moestl <tmoestl@gmx.net>
21:
22: Set sockaddr.sa_family on outgoing address, patch from
23: David Symonds <xoxus@usa.net>
24:
25: Patch to clear cache on SIGHUP
26: from Jason L. Wagner <nialscorva@yahoo.com>
27:
28: Fix bad bug resulting from not initialising value-result
29: address-length parameter to recvfrom() and accept() - it
30: worked by luck before!
31:
32: release 0.95 Major rewrite: remove calls to gethostbyname() and talk
33: directly to the upstream server(s) instead.
34: This has many advantages.
35: (1) Dnsmasq no longer blocks during long lookups.
36: (2) All query types are handled now, (eg MX) not just internet
37: address queries. Addresses are cached, all other
38: queries are forwarded directly.
39: (3) Time-to-live data from upstream server is read and
40: used by dnsmasq to purge entries from the cache.
41: (4) /etc/hosts is still read and its contents served (unless
42: the -h option is given).
43: (5) Dnsmasq can get its upstream servers from
44: a file other than /etc/resolv.conf (-r option) this allows
45: dnsmasq to serve names to the machine it is running
46: on (put nameserver 127.0.0.1 in /etc/resolv.conf and
47: give dnsmasq the option -r /etc/resolv.dnsmasq)
48: (6) Dnsmasq will re-read its servers if the
49: modification time of resolv.conf changes. Along with
50: 4 above this allows nameservers to be set
51: automatically by ppp or dhcp.
52:
53: A really clever NAT-like technique allows the daemon to have lots
54: of queries in progress, but still remain very lightweight.
55: Dnsmasq has a small footprint and normally doesn't allocate
56: any more memory after start-up. The NAT-like forwarding was
57: inspired by a suggestion from Eli Chen <eli@routefree.com>
58:
1.1.1.2 ! misho 59: release 0.96 Fixed embarrassing thinko in cache linked-list code.
1.1 misho 60:
61: release 0.98 Some enhancements and bug-fixes.
62: Thanks to "Denis Carre" <denis.carre@laposte.net> and Martin
63: Otte <otte@essc.psu.edu>
64:
65: (1) Dnsmasq now always sets the IP source address
66: of its replies correctly. Older versions would not always
67: do this on multi-homed and IP aliased hosts, which violates
68: the RFC.
69: (2) Dnsmasq no longer crashes if a server loop is created
70: (ie dnsmasq is told to use itself as an upstream server.)
71: Now it just logs the problem and doesn't use the bad
72: server address.
73: (3) Dnsmasq should now forward (but not cache) inverse queries
74: and server status queries; this feature has not been tested.
75: (4) Don't write the pid file when in non-daemon mode.
76: (5) Create the pid file mode 644, rather then 666 (!).
77: (6) Generate queries to upstream nameservers with unpredictable
78: ids, to thwart DNS spoofers.
79: (7) Dnsmasq no longer forwards queries when the
80: "recursion desired" bit is not set in the header.
1.1.1.2 ! misho 81: (8) Fixed getopt code to work on compilers with unsigned char.
1.1 misho 82:
83: release 0.991 Added -b flag: when set causes dnsmasq to always answer
84: reverse queries on the RFC 1918 private IP space itself and
85: never forward them to an upstream server. If the name is not in
86: /etc/hosts, dnsmasq replies with the dotted-quad address.
87:
88: Fixed a bug which stopped dnsmasq working on a box with
89: two or more interfaces with the same IP address.
90:
1.1.1.2 ! misho 91: Fixed caching of CNAMEs. Previously, a CNAME which pointed
1.1 misho 92: to a name with many A records would not have all the addresses
93: returned when being answered from the cache.
94:
95: Thanks to "Steve Hardy" <s.a.hardy@connectux.com> for his input
96: on these fixes.
97:
98: Fixed race which could cause dnsmasq to miss the second of
99: two closely-spaced updates of resolv.conf (Thanks to Eli Chen
100: for pointing this out.)
101:
102: Fixed a bug which could cause dnsmasq to fail to cache some
103: dns names.
104:
105: release 0.992 Small change to memory allocation so that names in /etc/hosts
106: don't use cache slots. Also make "-c 0" flag meaningfully
107: disable caching completely.
108:
109: release 0.993 Return only the first (canonical) name from an entry in
110: /etc/hosts as reply to reverse query.
111:
112: Handle wildcard queries for names/addresses in /etc/hosts
113: this is mainly to allow reverse lookups by dig to succeed.
114: (Bug reported by Simon J. Rowe" <srowe@mose.org.uk>)
115:
116: Subtle change to the logic which selects which of multiple
117: upstream servers we send queries to. This fixes a problem
118: where dnsmasq continuously sends queries to a server which
119: is returning error codes and ignores one which is working.
120:
121: release 0.994 Fixed bug which broke lookup of names in /etc/hosts
122: which have upper-case letters in them. Thanks for Joao Clemente
123: for spotting that one.
124:
125: Output cache statistics on receipt of SIGUSR1. These go
126: to syslog except in debug (-d) mode, when a complete cache
127: dump goes to stdout. Suggestion from Joao Clemente, code
128: based in John Volpe's.
129:
130: Accept GNU long options on the command line. Code from
131: John Volpe for this.
132:
133: Split source code into multiple files and produced
134: a proper makefile.
135:
136: Included code from John Volpe to parse dhcp.leases file
137: written by ISC dhcpd. The hostnames in the leases file are
138: added to the cache and updated as dhcpd updates the
139: leases file. The code has been heavily re-worked by me,
140: so any bugs are probably mine.
141:
142: release 0.995 Small tidy-ups to signal handling and cache code.
143:
144: release 0.996 Added negative caching: If dnsmasq gets a "no such domain" reply
145: from an upstream nameserver, it will cache that information
146: for a time specified by the SOA RR in the reply. See RFC 2308
147: for details. This is useful with resolver libraries
148: which append assorted suffices to non-FQDN in an attempt to
149: resolve them, causing useless cache misses.
150:
151: Added -i flag, which restricts dnsmasq to offering name service
152: only on specified interfaces.
153:
154: release 0.997 Deleted INSTALL script and added "install" target to makefile.
155:
156: Stopped distributing binaries in the tarball to avoid
157: libc version clashes.
158:
159: Fixed interface detection code to
160: remove spurious startup errors in rare circumstances.
161:
162: Dnsmasq now changes its uid, irrevocably, to nobody after
163: startup for security reasons. Thanks to Peter Bailey for
164: this patch.
165:
166: Cope with infinite DHCP leases. Patch thanks to
167: Yaacov Akiba Slama.
168:
169: Added rpm control files to .tar.gz distribution. Thanks to
170: Peter Baldwin at ClarkConnect for those.
171:
172: Improved startup script for rpms. Thanks to Yaacov Akiba Slama.
173:
174: release 1.0 Stable release: dnsmasq is now considered feature-complete
175: and stable.
176:
177: release 1.1 Added --user argument to allow user to change to
178: a different userid.
179:
180: Added --mx-target argument to allow mail to be delivered
181: away from the gateway machine running dnsmasq.
182:
183: Fixed highly obscure bug with wildcard queries for
184: DHCP lease derived names.
185:
186: Moved manpage from section 1 to section 8.
187:
188: Added --no-poll option.
189: Added Suse-rpm support.
190: Thanks to Joerg Mayer for the last two.
191:
192: release 1.2 Added IPv6 DNS record support. AAAA records are cached
193: and read from /etc/hosts. Reverse-lookups in the
1.1.1.2 ! misho 194: ip6.int and ip6.arpa domains are supported. Dnsmasq can
1.1 misho 195: talk to upstream servers via IPv6 if it finds IP6 addresses
196: in /etc/resolv.conf and it offers DNS service automatically
197: if IPv6 support is present in the kernel.
198:
199: Extended negative caching to NODATA replies.
200:
201: Re-vamped CNAME processing to cope with RFC 2317's use of
202: CNAMES to PTR RRs in CIDR.
203:
204: Added config.h and a couple of symbols to aid
205: compilation on non-linux systems.
206:
207: release 1.3 Some versions of the Linux kernel return EINVAL rather
208: then ENPROTONOSUPPORT when IPv6 is not available,
209: causing dnsmasq to bomb out. This release fixes that.
210: Thanks to Steve Davis for pointing this one out.
211:
212: Trivial change to startup logic so that dnsmasq logs
213: its stuff and reads config files straight away on
214: starting, rather than after the first query - principle
215: of least surprise applies here.
216:
1.1.1.2 ! misho 217: release 1.4 Fix a bug with DHCP lease parsing which broke in
1.1 misho 218: non-UTC timezones. Thanks to Mark Wormgoor for
219: spotting and diagnosing this. Fixed versions in
220: the .spec files this time. Fixed bug in Suse startup
221: script. Thanks to Didi Niklaus for pointing this out.
222:
223: release 1.5 Added --filterwin2k option which stops dnsmasq from forwarding
224: "spam" queries from win2k boxes. This is useful to stop spurious
225: connections over dial-on-demand links. Thanks to Steve Hardy
226: for this code.
227:
228: Clear "truncated" bit in replies we return from upstream. This
229: stops resolvers from switching to TCP, which is pointless since
230: dnsmasq doesn't support TCP. This should solve problems
231: in resolving hotmail.com domains.
232:
233: Don't include getopt.h when Gnu-long-options are disabled -
234: hopefully this will allow compilation on FreeBSD.
235:
236: Added the --listen-address and --pid-file flags.
237:
238: Fixed a bug which caused old entries in the DHCP leases file
239: to be used in preference to current ones under certain
240: circumstances.
241:
242: release 1.6 If a machine gets named via DHCP and the DHCP name doesn't have
243: a domain part and domain suffix is set using the -s flag, then
244: that machine has two names with the same address, with and
245: without the domain suffix. When doing a _reverse_ lookup to
246: get the name, the "without suffix" name used to be returned,
247: now the "with suffix" one gets returned instead. This change
248: suggested by Arnold Schulz.
249:
250: Fixed assorted typos in the documentation. Thanks
251: to David Kimdon.
252:
253: Subtle rearrangement to the downloadable tarball, and stopped
254: distributing .debs, since dnsmasq is now an official Debian
255: package.
256:
257: release 1.7 Fix a problem with cache not clearing properly
258: on receipt of SIGHUP. Bug spotted by Sat Deshpande.
259:
260: In group-id changing code:
1.1.1.2 ! misho 261: 1) Drop supplementary groups.
1.1 misho 262: 2) Change gid before dropping root (patch from Soewono Effendi.)
263: 3) Change group to "dip" if it exists, to allow access
264: to /etc/ppp/resolv.conf (suggestion from Jorg Sommer.)
265: Update docs to reflect above changes.
266:
267: Other documentation changes from David Miller.
268: Added suggested script fragment for dhcpcd.exe.
269:
270: release 1.8 Fix unsafe use of tolower() macro - allows linking against
271: ulibc. (Patches from Soewono Effendi and Bjorn Andersson.)
272:
273: Fix typo in usage string.
274:
275: Added advice about RedHat PPP configuration to
276: documentation. (Thanks to C. Lee Taylor.)
277:
278: Patches to fix problems on BSD systems from Marc Huber
279: and Can Erkin Acar. These add the options
280: HAVE_ARC4RANDOM and HAVE_SOCKADDR_SA_LEN to config.h.
281: Elaborated config.h - should really use autoconf.
282:
283: Fix time-to-live calculation when chasing CNAMEs.
284:
285: Fix use-after-free and missing initialisation bugs in
286: the cache code. (Thanks to Marc Huber.)
287:
288: Builds on Solaris 9. (Thanks to Marc Huber.)
289:
290: release 1.9 Fixes to rpm .spec files.
291:
292: Don't put expired DHCP entries into the cache only to
293: throw them away again.
294:
295: Put dnsmasq on a severe memory diet: this reduces both
296: the amount of heap space used and the stack size
297: required. The difference is not really visible with
298: bloated libcs like glibc, but should dramatically reduce
299: memory requirements when linked against ulibc for use on
1.1.1.2 ! misho 300: embedded routers, and that's the point really. Thanks to
1.1 misho 301: Matthew Natalier for prompting this.
302:
303: Changed debug mode (-d) so that all logging appears on
304: stderr as well as going to syslogd.
305:
306: Added HAVE_IPV6 config symbol to allow compilation
307: against a libc which doesn't have IPv6 support.
308:
309: Added a facility to log all queries, enabled with -q flag.
310:
311: Fixed packet size checking bug in address extraction code.
312:
313: Halved default cache size - 300 was way OTT in typical use.
314:
315: Added self-MX function, enabled by -e flag. Thanks to
316: Lyonel Vincent for the patch.
317:
318: Added HAVE_FORK config symbol and stuff to support
319: uClinux. Thanks to Matthew Natalier for uClinux stuff.
320:
321: release 1.10 Log warnings if resolv.conf or dhcp.leases are not
1.1.1.2 ! misho 322: accessible for any reason, as suggested by Hinrich Eilts.
1.1 misho 323:
324: Fixed wrong address printing in error message about
325: no interface with address.
326:
1.1.1.2 ! misho 327: Updated docs and split installation instructions into setup.html.
1.1 misho 328:
329: Fix bug in CNAME chasing code: One CNAME pointing
330: to many A records would lose A records after the
331: first. This bug was introduced in version 1.9.
332:
333: Log startup failures at level Critical as well as
334: printing them to standard error.
335: Exit with return code 1 when given bad options.
336:
337: Cleaned up code for no-cache operation.
338:
339: Added -o option which forces dnsmasq to use to
340: upstream servers in the order they appear in /etc/resolv.conf.
341:
342: Added upstream server use logging.
343:
344: Log full cache dump on receipt of SIGUSR1 when query
345: logging is enabled (-q switch).
346:
347: Added -S option to directly specify upstream servers and
348: added ability to direct queries for specific domains to
1.1.1.2 ! misho 349: specific servers. Suggested by Jens Vonderheide.
1.1 misho 350:
351: Upgraded random ID generation - patch from Rob Funk.
352:
353: Fixed reading of domains in arguments with capital
354: letters or trailing periods.
355:
356: Fixed potential SEGV when given bad options.
357:
358: Read options from /etc/dnsmasq.conf if it exists.
359: Do sensible things with missing parameters, eg
360: "--resolv-file=" turns off reading /etc/resolv.conf.
361:
362: release 1.11 Actually implement the -R flag promised in the 1.10 man page.
363:
364: Improve and rationalise the return codes in answers to
365: queries. In the case that there are no available
366: upstream servers to forward a query to, return REFUSED.
367: This makes sendmail work better on modem connected
368: systems when the modem link is down (Thanks to Roger Plant).
369: Cache and return the NXDOMAIN status of failed queries:
370: this makes the `host` command work when traversing search
371: paths (Thanks to Peter Bailey). Set the "authoritative"
372: bit in replies containing names from /etc/hosts or DHCP.
373:
374: Tolerate MS-DOS style line ending codes in /etc/hosts
375: and /etc/resolv.conf, for people who copy from winsock
376: installations.
377:
378: Allow specification of more than one resolv.conf file. This is
379: intended for laptops which connect via DHCP or
380: PPP. Whichever resolv.conf was updated last is used.
381:
382: Allow -S flags which specify a domain but no server
383: address. This gives local domains which are never forwarded.
384:
385: Add -E flag to automatically add the domain suffix to
386: names in /etc/hosts -suggestion from Phil Harman.
387:
388: Always return a zero time-to-live for names derived from
1.1.1.2 ! misho 389: DHCP which stops anything else caching these
1.1 misho 390: names. Previously the TTL was derived from the lease
391: time but that is incorrect since a lease can be given
392: up early: dnsmasq would know this but anything with the
393: name cached with long TTL would not be updated.
394:
1.1.1.2 ! misho 395: Extended HAVE_IPV6 config flag to allow compilation on
1.1 misho 396: old systems which don't have modern library routines
397: like inet_ntop(). Thanks to Phil Harman for the patch.
398:
399: release 1.12 Allow more than one domain in server config lines and
400: make "local" a synonym for "server". This makes things
401: like "local=/localnet/thekelleys.org.uk/" legal. Allow
402: port to specified as part of server address.
403:
404: Allow whole domains to have an IP address specified
405: in /etc/dnsmasq.conf. (/etc/hosts doesn't work domains).
406: address=/doubleclick.net/127.0.0.1 should catch all
407: those nasty banner ads. Inspired by a patch
408: from Daniel Gryniewicz
409:
410: Log the source of each query when logging switched on.
411:
412: Fix bug in script fragment for dhcpcd - thanks to Barry Stewart.
413:
414: Fix bug which meant that strict-order and self-mx were
415: always enabled.
416:
417: Builds with Linux libc5 now - for the Freesco project.
418:
419: Fixed Makefile installation script (patch from Silvan
420: Minghetti) and added CC and CFLAGS variables.
421:
422: Improve resource allocation to reduce vulnerability to
423: DOS attacks - the old version could have all queries
424: blocked by a continuous high-speed stream of
425: queries. Now some queries will succeed, and the excess
426: will be rejected with a server fail error. This change also
427: protects against server-loops; setting up a resolving
428: loop between two instances of dnsmasq is no longer
429: catastrophic. The servers will continue to run, looped
430: queries fail and a warning is logged. Thanks to C. Lee
431: Taylor for help with this.
432:
433: release 1.13 Added support for building rpms suitable for modern Suse
434: systems. (patch from Andi <cambeis@netplace.de>)
435:
436: Added options --group, --localmx, --local-ttl,
437: --no-negcache, --addn-host.
438:
439: Moved all the various rpm-building bits into /rpm.
440:
441: Fix builds with glibc 2.1 (thanks to Cristian
442: Ionescu-Idbohrn)
443:
444: Preserve case in domain names, as per RFC1035.
445:
446: Fixed ANY queries to domains with --address specification.
447:
448: Fixed FreeBSD build. (thanks to Steven Honson)
449:
450: Added -Q option which allows a specified port to be used
451: to talk to upstream servers. Useful for people who want
452: very paranoid firewalls which open individual UDP port.
453: (thanks to David Coe for the patch)
454:
455: release 1.14 Fixed man page description of -b option which confused
456: /etc/hosts with /etc/resolv.conf. (thanks to Christopher
457: Weimann)
458:
459: Fixed config.h to allow building under MACOS X and glibc
460: 2.0.x. (thanks to Matthew Gregan and Serge Caron)
461:
462: Added --except-interface option. (Suggested by Serge Caron)
463:
464: Added SIGUSR2 facility to re-scan for new
465: interfaces. (Suggested by Serge Caron)
466:
467: Fixed SEGV in option-reading code for invalid options.
468: (Thanks to Klaas Teschauer)
469:
470: Fixed man page to clarify effect of SIGUSR1 on
471: /etc/resolv.conf.
472: (Thanks to Klaas Teschauer)
473:
1.1.1.2 ! misho 474: Check that received queries have only rfc1035-legal characters
1.1 misho 475: in them. This check is mainly to avoid bad strings being
476: sent to syslog.
477:
478: Fixed &&/& confusion in option.c and added DESTDIR
479: variable for "make install" (Thanks to Osvaldo
480: Marques for the patch.)
481:
482: Fixed /etc/hosts parsing code to cope with MS-DOS
483: line-ends in the file. This was supposed to be done in
484: version 1.11, but something got missed. (Thanks to Doug
485: Copestake for helping to find this.)
486:
487: Squash repeated name/address pairs read from hosts
488: files.
489:
490: Tidied up resource handling in util.c (Thanks to
491: Cristian Ionescu-Idbohrn).
492:
493: Added hashed searching of domain names. People are starting
494: to use dnsmasq with larger loads now, and bigger caches,
495: and large lists of ad-block addresses. This means doing
496: linear searches can start to use lots of CPU so I added hashed
497: searching and seriously optimised the cache code for
498: algorithmic efficiency. Also upped the limit on cache
499: size to 10000.
500:
501: Fixed logging of the source of names from the additional
502: hosts file and from the "bogus private address" option.
503:
504: Fixed spurious re-reading of empty lease files. (Thanks
505: to Lewis Baughman for spotting this.)
506:
507: Fixed building under uclibc (patch from Cristian Ionescu-Idbohrn)
508:
509: Do some socket tweaking to allow dnsmasq to co-exist
510: with BIND. Thanks to Stefan 'Sec' Zehl for the patch.
511:
512: release 1.15 Added --bogus-nxdomain option.
513:
514: Restrict checking of resolv.conf and DHCP leases files
515: to once per second. This is intended to improve
516: performance under heavy loads. Also make a system call
517: to get the current time once per query, rather than four
518: times.
519:
520: Increased number of outstanding queries to 150 in
521: config.h
522:
523: release 1.16 Allow "/" characters in domain names - this fixes
524: caching of RFC 2317 CNAME-PTR records.
525:
526: Fixed brain-fart in -B option when GETOPT_LONG not
527: enabled - thanks to Steven Young and Jason Miller
528: for pointing this out.
529:
530: Generalised bogus-nxdomain code: allow more than one
531: address to check, and deal with replies with multiple
532: answer records. (Based on contribution from Humberto
533: Massa.)
534:
535: Updated the documentation to include information about
536: bogus-nxdomain and the Verisign tragedy.
537:
538: Added libraries needed on Solaris to Makefile.
539:
540: Added facility to set source address in queries to
541: upstream nameservers. This is useful with multihomed
542: hosts, especially when using VPNs. Thanks to Tom Fanning
543: for suggesting this feature.
544:
545: Tweaked logging: log to facility LOCAL0 when in
546: debug/no-daemon mode and changed level of query logging
547: from INFO to DEBUG. Make log options controllable in
548: config.h
549:
550: release 1.17 Fixed crash with DHCP hostnames > 40 characters.
551:
1.1.1.2 ! misho 552: Fixed name-comparison routines to not depend on Locale,
1.1 misho 553: in theory this versions since 1.15 could lock up or give
554: wrong results when run with locale != 'C'.
555:
556: Fix potential lockup in cache code. (thanks to Henning
557: Glawe for help chasing this down.)
558:
559: Made lease-file reader bullet-proof.
560:
561: Added -D option, suggested by Peter Fichtner.
562:
563: release 1.18 Added round-robin DNS for names which have more than one
564: address. In this case all the addresses will be
565: returned, as before, but the order will change on each
566: query.
567:
568: Remove stray tolower() and isalnum() calls missed in
569: last release to complete LOCALE independence.
570:
571: Allow port numbers in source-address specifications.
572:
573: For hostnames without a domain part which don't get
574: forwarded because -D is in effect, return NXDOMAIN not
575: an empty reply.
576:
1.1.1.2 ! misho 577: Add code to return the software version in response to the
1.1 misho 578: correct magic query in the same way as BIND. Use
579: "dig version.bind chaos txt" to make the query.
580:
581: Added negative caching for PTR (address to name) records.
582:
583: Ensure that names of the form typically used in PTR queries
584: (ie w.x.yz.in-addr.arpa and IPv6 equivalents) get
585: correct answers when queried as other types. It's
586: unlikely that anyone would do this, but the change makes
587: things pedantically correct.
588:
589: Taught dnsmasq to understand "bitstring" names, as these
590: are used for PTR lookups of IPv6 addresses by some
591: resolvers and lookup tools. Dnsmasq now understands both
592: the ip6.int domain and the ip6.arpa domain and both
593: nibble and bitstring formats so it should work with any
594: client code. Standards for this stuff have flip-flopped
595: over the last few years, leaving many different clients
596: in their wake. See RFC2673 for details of bitstrings.
597:
598: Allow '_' characters in domain names: Legal characters
599: are now [a-z][A-Z].-_ Check names read from hosts files
600: and leases files and reject illegal ones with a message
601: in syslog.
602:
603: Make empty domain names in server and address options
604: have the special meaning "unqualified
605: names". (unqualified names are names without any dots in
606: them). It's now possible to do server=//1.2.3.4 and have
607: unqualified names sent to a special nameserver.
608:
609: release 2.0rc1
610: Moved source code into src/ directory.
611:
612: Fixes to cure compilation breakage when HAVE_IPV6 not
613: set, thanks to Claas Hilbrecht.
614:
615: BIG CHANGE: added an integrated DHCP server and removed
616: the code to read ISC dhcp.leases. This wins in terms
617: of ease of setup and configuration flexibility and
618: total machine resources consumed.
619:
620: Re-jiged the signal handling code to remove a race
621: condition and to be more portable.
622:
623: release 2.0
624: Thanks to David Ashworth for feedback which informed many
625: of the fixes below.
626:
627: Allow hosts to be specified by client ID in dhcp-hosts
628: options. These are now one of
629: dhcp-host=<hardware addr>,....
630: dhcp-host=id:<hex client id>,.....
631: dhcp-host=id:<ascii client id>,.....
632:
633: Allow dhcp-host options to specify any IP address on the
634: DHCP-served network, not just the range available for
635: dynamic allocation.
636:
637: Allow dhcp-host options for the same host with different
1.1.1.2 ! misho 638: IP addresses where the correct one will be selected for
1.1 misho 639: the network the host appears on.
640:
641: Fix parsing of --dhcp-option to allow more than one
642: IP address and to allow text-type options.
643:
644: Inhibit use of --dhcp-option to send hostname DHCP options.
645:
646: Update the DNS with DHCP information after re-reading
647: /etc/hosts so that any DHCP derived names which have been
648: shadowed by now-deleted hosts entries become visible.
649:
650: Fix typos in dnsmasq.conf.example
651:
652: Fixes to Makefile(s) to help pkgsrc packaging - patch
653: from "pancake".
654:
655: Add dhcp-boot option to support network boot.
656:
657: Check for duplicate IP addresses in dhcp-hosts lines
658: and refuse to run if found. If allowed to remain these
659: can provoke an infinite loop in the DHCP protocol.
660:
661: Attempted to rationalise the .spec files for rpm
662: building. There are now files for Redhat, Suse and
663: Mandrake. I hope they work OK.
664:
665: Fixed hard-to-reproduce crash involving use of local
666: domains and IPv6 queries. Thanks to Roy Marples for
667: helping to track that one down.
668:
669: release 2.1
670: Thanks to Matt Swift and Dag Wieers for many suggestions
671: which went into this release.
672:
673: Tweak include files to allow compilation on FreeBSD 5
674:
675: Fix unaligned access warnings on BSD/Alpha.
676:
1.1.1.2 ! misho 677: Allow empty DHCP options, like so: dhcp-option=44
1.1 misho 678:
679: Allow single-byte DHCP options like so: dhcp-option=20,1
680:
681: Allow comments on the same line as options in
682: /etc/dnsmasq.conf
683:
684: Don't complain when the same name and address is
685: allocated to a host using DHCP and /etc/hosts.
686:
687: Added to the example configuration the dnsmasq equivalent
688: of the ISC dhcpd settings given in
689: http://www.samba.org/samba/ftp/docs/textdocs/DHCP-Server-Configuration.txt
690:
691: Fixed long-existing strangeness in Linux IPv6 interface
692: discovery code. The flags field in /proc/net/if_inet6 is
693: _not_ the interface flags.
694:
695: Fail gracefully when getting an ENODEV error when trying
696: to bind an IPv6 socket, rather than bailing out. Thanks
697: to Jan Ischebeck for feedback on that.
698:
699: Allow the name->address mapping for static DHCP leases to
700: be set by /etc/hosts. It's now possible to have
701: dhcp-host=<mac addr>,wibble
702: or even
703: dhcp-host=wibble
704: and in /etc/hosts have
705: wibble 1.2.3.4
706: and for the correct thing to happen. Note that some sort
707: of dhcp-host line is still needed, it's not possible for
708: random host to claim an address in /etc/hosts without
709: some explicit configuration.
710:
711: Make 0.0.0.0 in a dhcp-option to mean "the machine
712: running dnsmasq".
713:
714: Fix lease time spec when specified in dhcp-range and not
715: in dhcp-host, previously this was always one hour.
716:
717: Fix problem with setting domains as "local only". -
718: thanks to Chris Schank.
719:
720: Added support for max message size DHCP option.
721:
722: release 2.2
723: Fix total lack for DHCP functionality on
724: Linux systems with IPv6 enabled. - thanks to
725: Jonathon Hudson for spotting that.
726:
727: Move default config file under FreeBSD - patch from
728: Steven Honson
729:
730: release 2.3
731: Fix "install" makefile target. (reported by Rob Stevens)
732:
733: Ensure that "local=/domain/" flag is obeyed for all
734: queries on a domain, not just A and AAAA. (Reported by
735: Peter Fichtner.)
736:
737: Handle DHCPDECLINE messages and provide an error message
738: in DHCPNAK messages.
739:
740: Add "domain" setting example to
741: dnsmasq.conf.example. Thanks to K P Kirchdorfer for
742: spotting that it was missing.
743:
744: Subtle change to the DHCPREQUEST handling code to work
745: around a bug in the DHCP client in HP Jetdirect printers.
746: Thanks to Marko Stolle for finding this problem.
747:
1.1.1.2 ! misho 748: Return DHCP T1 and T2 times, with "fuzz" to desynchronise lease
1.1 misho 749: renewals, as specified in the RFC.
750:
751: Ensure that the END option is always present in DHCP
752: packets , even if the packet is too small to fit all
753: the requested options.
754:
755: Handle larger-than-default DHCP packets if required, up
756: to the ethernet MTU.
757:
758: Fix a couple of places where the return code from
759: malloc() was not checked.
760:
761: Cope with a machine taking a DHCP lease and then moving
762: network so that the lease address is no longer valid.
763:
764: The DHCP server will now work via a BOOTP relay - remote
765: networks are configured with the dhcp-range option the
766: same as directly connected ones, but they need an
767: additional netmask parameter. Eg
768: --dhcp-range=192.168.4.10,192.168.4.50,255.255,255.0
769: will enable DHCP service via a BOOTP relay on the
770: 192.168.4.0 network.
771:
772: Add a limit on the number of available DHCP leases,
773: otherwise the daemon could be DOSed by a malicious
774: host. The default is 150, but it can be changed by the
775: dhcp-lease-max option.
776:
777: Fixed compilation on OpenBSD (thanks to Frederic Brodbeck
778: for help with that.)
779:
780: Reworked the DHCP network handling code for two good
781: effects: (1) The limit of one network only for DHCP on
782: FreeBSD is now gone, (2) The DHCP server copes with
783: dynamically created interfaces. The one-interface
784: limitation remains for OpenBSD, which is missing
785: extensions to the socket API which have been in Linux
786: since version 2.2 and FreeBSD since version 4.8.
787:
788: Reworked the DNS network code to also cope with
789: dynamically created interfaces. dnsmasq will now listen
790: to the wildcard address and port 53 by default, so if no
791: --interface or --address options are given it will handle
792: dynamically created interfaces. The old behaviour can be
793: restored with --bind-interfaces for people running BIND
794: on one interface and dnsmasq on another. Note that
795: --interface and --address options still work, but the
796: filtering is done by dnsmasq, rather then the kernel.
797: This works on Linux, and FreeBSD>=5.0. On systems which
798: don't support the required API extensions, the old
799: behaviour is used, just as if --bind-interfaces had been set.
800:
801: Allow IPv6 support to be disabled at compile time. To do
802: that, add -DNO_IPV6 to the CFLAGS. Thanks to Oleg
803: I. Vdovikin for the suggestion to do that.
804:
805: Add ability to set DHCP options per network. This is done
806: by giving a network an identifier like this:
807: dhcp-range=red-net,192.168.0.10,192.168.0.50
808: and then labeling options intended for that network only
809: like this:
810: dhcp-option=red-net,6,1.1.1.1
811: Thanks to Oleg Vdovikin for arguing that one through.
812:
813: Made errors in the configuration file non-fatal: dnsmasq
814: will now complain bitterly, but continue.
815:
816: Added --read-ethers option, to allow dnsmasq to pull
817: static DHCP information from that file.
818: Thanks to Andi Cambeis for that suggestion.
819:
820: Added HAVE_BROKEN_RTC compilation option to support
821: embedded systems without a stable RTC. Oleg Vdovikin
822: helped work out how to make that work.
823:
824: release 2.4
825: Fixed inability to start when the lease file doesn't
826: already exist. Thanks to Dag Wieers for reporting that.
827:
828: Fixed problem were dhcp-host configuration options did
829: not play well with entries in /etc/ethers for the same
830: host. Thanks again to Dag Wieers.
831:
832: Tweaked DHCP code to favour moving to a newly-configured
833: static IP address rather than an old lease when doing
834: DHCP allocation.
835:
836: Added --alias configuration option. This provides IPv4
837: rewrite facilities like Cisco "DNS doctoring". Suggested
838: by Chad Skeeters.
839:
840: Fixed bug in /etc/ethers parsing code triggered by tab
1.1.1.2 ! misho 841: characters. Kudos to Dag Wieers for helping to nail that
1.1 misho 842: one.
843:
844: Added "bind-interfaces" option correctly.
845:
846: release 2.5
847: Made "where are we allocating addresses?" code in DHCP
848: server cope with requests via a relay which is on a
849: directly connected network for which there is not a
850: configured netmask. This strange state of affairs occurs
851: with win4lin. Thanks to Alex Melt and Jim Horner for bug
852: reports and testing with this.
853:
854: Fixed trivial-but-irritating missing #include which broke
855: compilation on *BSD.
856:
857: Force --bind-interfaces if IP-aliased interface
858: specifications are used, since the sockets API provides
859: no other sane way to determine which alias of an
860: interface a packet was sent to. Thanks to Javier Kohen
861: for the bug report.
862:
863: release 2.6
864: Support Token Ring DHCP. Thanks to Dag Wieers for help
865: testing. Note that Token ring support only works on Linux
866: currently.
867:
868: Fix compilation on MacOS X. Thanks to Bernhard Ehlers for
869: the patch.
870:
871: Added new "ignore" keyword for
872: dhcp-host. "dhcp-host=11:22:33:44:55:66,ignore" will
873: cause the DHCP server to ignore any host with the given
874: MAC address, leaving it to other servers on the
875: network. This also works with client-id and hostnames.
876: Suggestion by Alex Melt.
877:
878: Fixed parsing of hex client IDs. Problem spotted by Peter
879: Fichtner.
880:
881: Allow conf-file options in configuration file, to
882: provide an include function.
883:
884: Re-read /etc/ethers on receipt of SIGHUP.
885:
886: Added back the ability to read ISC dhcpd lease files, by
887: popular demand. Note that this is deprecated and for
888: backwards compatibility only. You can get back the 4K of
889: memory that the code occupies by undefining
890: "HAVE_ISC_READER" in src/config.h
891:
892: Added ability to disable "pool" DHCP address allocation
893: whilst leaving static leases working. The syntax is
894: "dhcp-range=192.168.0.0,static"
895: Thanks to Grzegorz Nosek for the suggestion.
896:
897: Generalized dnsmasq-rh.spec file to work on Mandrake too,
898: and removed dnsmasq-mdk.spec. Thanks to Doug Keller.
899:
900: Allow DHCP options which are tied to specific static
901: leases in the same way as to specific networks.
902:
903: Generalised the dhcp-option parser a bit to allow hex
904: strings as parameters. This is now legal:
905: dhcp-option=128,e4:45:74:68:00:00
906: Inspired by a patch from Joel Nordell.
907:
908: Changed the semantics of argument-less dhcp-options for
909: the default-setting ones, ie 1, 3, 6 and 28. Now, doing
910: eg, dhcp-option=3 stops dnsmasq from sending a default
911: router option at all. Thanks to Scott Emmons for pointing
912: out that this is useful.
913:
914: Fixed dnsmasq.conf parsing bug which interpreted port
915: numbers in server= lines as a comment. To start a
916: comment, a '#' character must now be a the start of a
917: line or preceded by whitespace. Thanks to Christian
918: Haggstrom for the bug report.
919:
920: release 2.7
921: Allow the dhcp-host specification of id:* which makes
922: dnsmasq ignore any client-id. This is useful to ensure
923: that a dual-boot machine sees the same lease when one OS
924: gives a client-id and the other doesn't. It's also useful
925: when PXE boot DHCP does not use client IDs but the OS it boots
926: does. Thanks to Grzegorz Nosek for suggesting this enhancement.
927:
928: No longer assume that ciaddr is zero in received DHCPDISCOVER
929: messages, just for security against broken clients.
930:
931: Set default of siaddr field to the address of the machine running
932: dnsmasq when not explicitly set using dhcp-boot
933: option. This is the ISC dhcpd behaviour.
934:
935: Send T1 and T2 options in DHCPOFFER packets. This is required
936: by the DHCP client in some JetDirect printers. Thanks
937: to Paul Mattal for work on this.
938:
939: Fixed bug with DHCP on OpenBSD reported by Dominique Jacquel.
940: The code which added loopback interfaces to the list
941: was confusing the DHCP code, which expected one interface only.
942: Solved by adding loopback interfaces to address list instead.
943:
944: Add dhcp-vendorclass option to allow options to be sent only
945: to certain classes of clients.
946:
947: Tweaked option search code so that if a netid-qualified
948: option is used, any unqualified option is ignored.
949:
950: Changed the method of picking new dynamic IP
951: addresses. This used to use the next consecutive
952: address as long it was free, now it uses a hash
953: from the client hardware address. This reduces the amount
954: of address movement for clients which let their lease
955: expire and allows consecutive DHCPOFFERS to the same host
956: to (almost always) be for the same address, without
957: storing state before a lease is granted.
958:
959: Tweaked option handling code to return all possible
960: options rather than none when DHCP "requested options"
961: field is missing. This fixes interoperability with
962: ancient IBM LANMAN DHCP clients. Thanks to Jim Louvau for
963: help with this.
964:
965: release 2.8
966: Pad DHCP packets to a minimum size of 300 bytes. This
967: fixes interoperability problems with the Linux in-kernel
968: DHCP/BOOTP client. Thanks to Richard Musil for
969: diagnosing this and supplying a patch.
970:
971: Fixed option-parsing bug and potential memory leak. Patch
972: from Richard Musil.
973:
974: Improved vendor class configuration and added user class
975: configuration. Specifically: (1) options are matched on
976: the netids from dhcp-range, dhcp-host, vendor class and
977: user class(es). Multiple net-ids are allowed and options
1.1.1.2 ! misho 978: are searched on them all. (2) matches against vendor class
1.1 misho 979: and user class are now on a substring, if the given
980: string is a substring of the vendor/user class, then a
981: match occurs. Thanks again to Richard Musil for prompting
982: this.
983:
984: Make "#" match any domain on --address and --server
985: flags. --address=/#/1.2.3.4 will return 1.2.3.4 for _any_
986: domain not otherwise matched. Of course
987: --server=/#/1.2.3.4 is exactly equivalent to
988: --server=1.2.3.4. Special request from Josh Howlett.
989:
990: Fixed a nasty bug which would cause dnsmasq to lose track
991: of leases for hosts which had a --dhcp-host flag without
992: a name specification. The mechanism for this was that
993: the hostname could get erroneously set as a zero-length
994: string and then written to the leases file as a
995: mal-formed line. Restarting dnsmasq would then lose the lease.
996: Alex Hermann's work helped chase down this problem.
997:
998: Add checks against DHCP clients which return zero-length
999: hostnames. This avoids the potential lease-loss problems
1.1.1.2 ! misho 1000: referred to above. Also, if a client sends a hostname when
1.1 misho 1001: it creates a lease but subsequently sends no or a
1002: zero-length hostname whilst renewing, continue to use the
1003: existing hostname, don't wipe it out.
1004:
1005: Tweaked option parsing to flag some parameter errors.
1006:
1007: release 2.9
1008: Fixed interface filter code for two effects: 1) Fixed bug
1009: where queries sent via loopback interface
1010: but to the address of another interface were ignored
1011: unless the loopback interface was explicitly configured.
1012: 2) on OpenBSD failure to configure one interface now
1.1.1.2 ! misho 1013: causes a fatal error on startup rather than a huge
1.1 misho 1014: stream of log messages. Thanks to Erik Jan Tromp for
1015: finding that bug.
1016:
1017: Changed server selection strategy to improve performance
1018: when there are many available servers and some are
1019: broken. The new algorithm is to pick as before for the
1020: first try, but if a query is retried, to send to all
1021: available servers in parallel. The first one to reply
1.1.1.2 ! misho 1022: then becomes preferred for the next query. This should
1.1 misho 1023: improve reliability without generating significant extra
1024: upstream load.
1025:
1026: Fixed breakage of special servers/addresses for
1027: unqualified domains introduced in version 2.8
1028:
1029: Allow fallback to "bind-interfaces" at runtime: Some
1.1.1.2 ! misho 1030: versions of *BSD seem to have enough stuff in the header
1.1 misho 1031: files to build but no kernel support. Also now log if
1032: "bind-interfaces" is forced on.
1033:
1034: Log replies from upstream servers which refuse to do
1035: recursion - dnsmasq is not a recursive nameserver and
1036: relies on upstream servers to do the recursion, this
1037: flags a configuration error.
1038:
1039: Disable client-id matching for hosts whose MAC address is
1040: read from /etc/ethers. Patch from Oleg I. Vdovikin.
1041:
1042: Extended --mx-host flag to allow arbitrary targets for MX
1043: records, suggested by Moritz Bunkus.
1044:
1045: Fixed build under NetBSD 2.0 - thanks to Felix Deichmann
1046: for the patch.
1047:
1048: Deal correctly with repeated addresses in /etc/hosts. The
1049: first name found is now returned for reverse lookups,
1050: rather than all of them.
1051:
1.1.1.2 ! misho 1052: Add back fatal errors when nonexistent
1.1 misho 1053: interfaces or interface addresses are given but only in
1054: "bind-interfaces" mode. Principle of least surprise applies.
1055:
1056: Allow # as the argument to --domain, meaning "read the
1057: domain from the first search directive in
1058: /etc.resolv.conf". Feature suggested by Evan Jones.
1059:
1060: release 2.10
1061: Allow --query-port to be set to a low port by creating and
1062: binding the socket before dropping root. (Suggestion from
1063: Jamie Lokier)
1064:
1065: Support TCP queries. It turned out to be possible to do
1066: this with a couple of hundred lines of code, once I knew
1067: how. The executable size went up by a few K on i386.
1068: There are a few limitations: data obtained via TCP is not
1069: cached, and dynamically-created interfaces may break under
1070: certain circumstances. Source-address or query-port
1071: specifications are ignored for TCP.
1072:
1073: NAK attempts to renew a DHCP lease where the DHCP range
1074: has changed and the lease is no longer in the allowed
1075: range. Jamie Lokier pointed out this bug.
1076:
1077: NAK attempts to renew a pool DHCP lease when a statically
1078: allocated address has become available, forcing a host to
1079: move to its allocated address. Lots of people have
1080: suggested this change and been rebuffed (they know who
1081: they are) the straws that broke the camel's back were Tim
1082: Cutts and Jamie Lokier.
1083:
1084: Remove any nameserver records from answers which are
1085: modified by --alias flags. If the answer is modified, it
1086: cannot any longer be authoritative.
1087:
1088: Change behaviour of "bogus-priv" option to return NXDOMAIN
1089: rather than a PTR record with the dotted-quad address as
1090: name. The new behaviour doesn't provoke tcpwrappers like
1091: the old behavior did.
1092:
1093: Added a patch for the Suse rpm. That changes the default
1094: group to one suitable for Suse and disables inclusion of
1095: the ISC lease-file reader code. Thanks to Andy Cambeis for
1096: his ongoing work on Suse packaging.
1097:
1098: Support forwarding of EDNS.0 The maximum UDP packet size
1099: defaults to 1280, but may be changed with the
1100: --edns-packet-max option. Detect queries with the do bit
1101: set and always forward them, since DNSSEC records are
1102: not cached. This behaviour is required to make
1103: DNSSECbis work properly though dnsmasq. Thanks to Simon
1104: Josefsson for help with this.
1105:
1106: Move default config file location under OpenBSD from
1107: /usr/local/etc/dnsmasq.conf to /etc/dnsmasq.conf. Bug
1108: report from Jonathan Weiss.
1109:
1110: Use a lease with matching MAC address for a host which
1111: doesn't present a client-id, even if there was a client ID
1112: at some point in the past. This reduces surprises when
1113: changing DHCP clients, adding id:* to a host, and from the
1114: semantics change of /etc/ethers in 2.9. Thanks to Bernard
1115: Sammer for finding that.
1116:
1117: Added a "contrib" directory and in it the dnslist utility,
1118: from Thomas Tuttle.
1119:
1120: Fixed "fail to start up" problems under Linux with IPv6
1121: enabled. It's not clear that these were an issue in
1122: released versions, but they manifested themselves when TCP
1123: support was added. Thanks to Michael Hamilton for
1124: assistance with this.
1125:
1126: version 2.11
1127: Fixed DHCP problem which could result in two leases in the
1128: database with the same address. This looked much more
1129: alarming then it was, since it could only happen when a
1130: machine changes MAC address but kept the same name. The
1131: old lease would persist until it timed out but things
1132: would still work OK.
1133:
1134: Check that IP addresses in all dhcp-host directives are
1135: unique and die horribly if they are not, since otherwise
1136: endless protocol loops can occur.
1137:
1138: Use IPV6_RECVPKTINFO as socket option rather than
1139: IPV6_PKTINFO where available. This keeps late-model FreeBSD
1140: happy.
1141:
1142: Set source interface when replying to IPv6 UDP
1143: queries. This is needed to cope with link-local addresses.
1144:
1145: version 2.12
1146: Added extra checks to ensure that DHCP created DNS entries
1147: cannot generate multiple DNS address->name entries. Thanks to
1148: Stefan Monnier for finding the exact set of configuration
1149: options which could create this.
1150:
1151: Don't set the the filterwin2k option in the example config
1152: file and add warnings that is breaks Kerberos. Thanks to
1153: Simon Josefsson and Timothy Folks for pointing that out.
1154:
1155: Log types of incoming queries as well as source and domain.
1156:
1157: Log NODATA replies generated as a result of the
1158: filterwin2k option.
1159:
1160: version 2.13
1161: Fixed crash with un-named DHCP hosts introduced in 2.12.
1162: Thanks to Nicolo Wojewoda and Gregory Gathy for bug reports.
1163:
1164: version 2.14
1165: Fix DHCP network detection for hosts which talk via a
1166: relay. This makes lease renewal for such hosts work
1167: correctly.
1168:
1169: Support RFC3011 subnet selectors in the DHCP server.
1170:
1171: Fix DHCP code to generate RFC-compliant responses
1172: to hosts in the INIT-REBOOT state.
1173:
1174: In the DHCP server, set the receive buffer size on
1175: the transmit-only packet socket to zero, to avoid
1176: waste of kernel buffers.
1177:
1178: Fix DHCP address allocation code to use the whole of
1179: the DHCP range, including the start and end addresses.
1180:
1181: Attempt an ICMP "ping" on new addresses before allocating
1182: them to leases, to avoid allocating addresses which are in use.
1183:
1184: Handle rfc951 BOOTP as well as DHCP for hosts which have
1185: MAC address to IP address mapping defined.
1186:
1187: Fix compilation under MacOS X. Thanks to Chris Tomlinson.
1188:
1189: Fix compilation under NetBSD. Thanks to Felix Deichmann.
1190:
1191: Added "keep-in-foreground" option. Thanks to Sean
1192: MacLennan for the patch.
1193:
1194: version 2.15
1195: Fixed NXDOMAIN/NODATA confusion for locally known
1.1.1.2 ! misho 1196: names. We now return a NODATA response for names which are
1.1 misho 1197: locally known. Now a query for (eg AAAA or MX) for a name
1198: with an IPv4 address in /etc/hosts which fails upstream
1199: will generate a NODATA response. Note that the query
1200: is still tried upstream, but a NXDOMAIN reply gets
1201: converted to NODATA. Thanks to Eric de Thouars, Eric
1202: Spakman and Mike Mestnik for bug reports/testing.
1203:
1204: Allow multiple dhcp-ranges within the same network. The
1205: original intention was that there would be a dhcp-range
1206: option for each network served, but there's no real reason
1207: not to allow discontinuous ranges within a network so this
1208: release adds support for that.
1209:
1210: Check for dhcp-ranges which are inconsistent with their
1211: netmask, and generate errors or warnings.
1212:
1213: Improve error messages when there are problems with
1214: configuration.
1215:
1216: version 2.16
1217: Fixed typo in OpenBSD-only code which stopped compilation
1218: under that OS. Chris Weinhaupl gets credit for reporting
1219: this.
1220:
1221: Added dhcp-authoritative option which restores non-RFC
1222: compliant but desirable behaviour of pre-2.14 versions and
1223: avoids long timeouts while DHCP clients try to renew leases
1224: which are unknown to dnsmasq. Thanks to John Mastwijk for
1225: help with this.
1226:
1227: Added support to the DHCP option code to allow RFC-3397
1228: domain search DHCP option (119) to be sent.
1229:
1230: Set NONBLOCK on all listening sockets to workaround non-POSIX
1231: compliance in Linux 2.4 and 2.6. This fixes rare hangs which
1.1.1.2 ! misho 1232: occurred when corrupted packets were received. Thanks to
1.1 misho 1233: Joris van Rantwijk for chasing that down.
1234:
1235: Updated config.h for NetBSD. Thanks to Martin Lambers.
1236:
1237: Do a better job of distinguishing between retransmissions
1238: and new queries when forwarding. This fixes a bug
1239: triggered by the polipo web cache which sends A and AAAA
1240: queries both with the same transaction-ID. Thanks to
1241: Joachim Berdal Haga and Juliusz Chroboczek for help with this.
1242:
1243: Rewrote cache code to store CNAMES, rather then chasing
1244: them before storage. This eliminates bad situations when
1245: clients get inconsistent views depending on if data comes
1246: from the cache.
1247:
1248: Allow for more than one --addn-hosts flag.
1249:
1250: Clarify logged message when a DHCP lease clashes with an
1251: /etc/hosts entry. Thanks to Mat Swift for the suggestion.
1252:
1253: Added dynamic-dnsmasq from Peter Willis to the contrib
1254: section.
1255:
1256: version 2.17
1257: Correctly deduce the size of numeric dhcp-options, rather
1258: than making wild guesses. Also cope with negative values.
1259:
1260: Fixed use of C library reserved symbol "index" which broke
1261: under certain combinations of library and compiler.
1262:
1263: Make bind-interfaces work for IPv6 interfaces too.
1264:
1265: Warn if an interface is given for listening which doesn't
1266: currently exist when not in bind-interfaces mode. (This is
1267: already a fatal error when bind-interfaces is set.)
1268:
1269: Allow the --interface and --except-interface options to
1270: take a comma-separated list of interfaces.
1271:
1272: Tweak --dhcp-userclass matching code to work with the
1273: ISC dhclient which violates RFC3004 unless its
1274: configuration is very warped. Thanks to Cedric Duval for
1275: the bug report.
1276:
1277: Allow more than one network-id tag in a dhcp-option. All
1278: the tags must match to enable the option.
1279:
1280: Added dhcp-ignore option to disable classes of hosts based
1281: on network-id tags. Also allow BOOTP options to be
1282: controlled by network tags.
1283:
1284: Fill in sname, file and siaddr fields in replies to
1285: DHCPINFORM messages.
1286:
1287: Don't send NAK replies to DHCPREQUEST packets for disabled
1288: clients. Credit to Cedric Duval for spotting this.
1289:
1290: Fix rare crash associated with long DNS names and CNAME
1291: records. Thanks to Holger Hoffstatte and especially Steve
1292: Grecni for help chasing that one down.
1293:
1294: version 2.18
1295: Reworked the Linux interface discovery code (again) to
1296: cope with interfaces which have only IPv6 addresses and
1297: interfaces with more than one IPv6 address. Thanks to
1298: Martin Pels for help with that.
1299:
1.1.1.2 ! misho 1300: Fix problems which occurred when more than one dhcp-range
1.1 misho 1301: was specified in the same subnet: sometimes parameters
1302: (lease time, network-id tag) from the wrong one would be
1303: used. Thanks to Rory Campbell-Lange for the bug report.
1304:
1305: Reset cache statistics when clearing the cache.
1306:
1307: Enable long command line options on FreeBSD when the
1308: C library supports them.
1309:
1310: version 2.19
1311: Tweaked the Linux-only interface discovery code to cope
1312: with interface-indexes larger than 8 bits in
1313: /proc/net/if_inet6. This only affects Linux, obviously.
1314: Thanks to Richard Atterer for the bug report.
1315:
1316: Check for under-length option fields in DHCP packets, a
1.1.1.2 ! misho 1317: zero length client-id, in particular, could seriously
1.1 misho 1318: confuse dnsmasq 'till now. Thanks to Will Murname for help
1319: with that.
1320:
1321: If a DHCP-allocated address has an associated name in
1322: /etc/hosts, and the client does not provide a hostname
1323: parameter and there is no hostname in a matching dhcp-host
1324: option, send the /etc/hosts name as the hostname in
1325: the DHCP lease. Thanks to Will Murname for the suggestion.
1326:
1327: version 2.20
1328: Allow more than one instance of dnsmasq to run on a
1329: machine, each providing DHCP service on a different
1330: interface, provided that --bind-interfaces is set. This
1331: configuration used to work, but regressed in version 2.14
1332:
1333: Fix compilation on Mac OS X. Thanks to Kevin Bullock.
1334:
1335: Protect against overlong names and overlong
1336: labels in configuration and from DHCP.
1337:
1338: Fix interesting corner case in CNAME handling. This occurs
1339: when a CNAME has a target which "shadowed" by a name in
1340: /etc/hosts or from DHCP. Resolving the CNAME would sneak
1341: the upstream value of the CNAME's target into the cache,
1342: alongside the local value. Now that doesn't happen, though
1343: resolving the CNAME still gives the unshadowed value. This
1344: is arguably wrong but rather difficult to fix. The main
1345: thing is to avoid getting strange results for the target
1346: due to the cache pollution when resolving the
1347: CNAME. Thanks to Pierre Habouzit for exploring the corner
1348: and submitting a very clear bug report.
1349:
1350: Fix subtle bug in the DNS packet parsing code. It's almost
1351: impossible to describe this succinctly, but the one known
1352: manifestation is the inability to cache the A record for
1353: www.apple.com. Thanks to Bob Alexander for spotting that.
1354:
1355: Support SRV records. Thanks to Robert Kean for the patches
1356: for this.
1357:
1358: Fixed sign confusion in the vendor-id matching code which
1359: could cause crashes sometimes. (Credit to Mark Wiater for
1360: help finding this.)
1361:
1362: Added the ability to match the netid tag in a
1363: dhcp-range. Combined with the ability to have multiple
1364: ranges in a single subnet, this provides a means to
1365: segregate hosts on different address ranges based on
1366: vendorclass or userclass. Thanks to Mark Wiater for
1367: prompting this enhancement.
1368:
1369: Added preference values for MX records.
1370:
1371: Added the --localise-queries option.
1372:
1373: version 2.21
1374: Improve handling of SERVFAIL and REFUSED errors. Receiving
1375: these now initiates search for a new good server, and a
1376: server which returns them is not a candidate as a good
1377: server. Thanks to Istvan Varadi for pointing out the
1378: problem.
1379:
1380: Tweak the time code in BROKEN_RTC mode.
1381:
1382: Sanity check lease times in dhcp-range and dhcp-host
1383: configurations and force them to be at least two minutes
1384: (120s) leases shorter than a minute confuse some clients,
1385: notably Apple MacOS X. Rory Campbell-Lange found this
1386: problem.
1387:
1388: Only warn once about an upstream server which is refusing to do
1389: recursive queries.
1390:
1391: Fix DHCP address allocation problem when netid tags are in
1.1.1.2 ! misho 1392: use. Thanks to Will Murname for the bug report and
1.1 misho 1393: subsequent testing.
1394:
1395: Add an additional data section to the reply for MX and SRV
1396: queries. Add support for DNS TXT records. Thanks to Robert
1397: Kean and John Hampton for prompts and testing of these.
1398:
1399: Apply address rewriting to records in the additional data section
1400: of DNS packets. This makes things like MX records work
1401: with the alias function. Thanks to Chad Skeeters for
1402: pointing out the need for this.
1403:
1404: Added support for quoted strings in config file.
1405:
1406: Detect and defeat cache-poisoning attacks which attempt to
1407: send (malicious) answers to questions we didn't
1408: send. These are ignored now even if the attacker manages
1409: to guess a random query-id.
1410:
1411: Provide DHCP support for interfaces with multiple IP
1412: addresses or aliases. This in only enabled under Linux.
1413: See the FAQ entry for details.
1414:
1415: Revisit the MAC-address and client-id matching code to
1416: provide saner behaviour with PXE boots, where some
1417: requests have a client-id and some don't.
1418:
1419: Fixed off-by-one buffer overflow in lease file reading
1420: code. Thanks to Rob Holland for the bug report.
1421:
1422: Added wildcard matching for MAC addresses in dhcp-host
1423: options. A sensible suggestion by Nathaniel McCallum.
1424:
1425: version 2.22
1426: Fixed build problems on (many) systems with older libc
1427: headers where <linux/types.h> is required before
1428: <linux/netlink.h>. Enabled HAVE_RTNETLINK under uclibc now
1429: that this fix is in place.
1430:
1431: Added support for encapsulated vendor-class-specific DHCP
1432: options. Thanks to Eric Shattow for help with this.
1433:
1434: Fix regression in 2.21 which broke commas in filenames and
1435: corrupted argv. Thanks to Eric Scott for the bugreport.
1436:
1437: Fixed stupid thinko which caused dnsmasq to wedge during
1438: startup with certain MX-record options. Another 2.21 regression.
1439:
1440: Fixed broken-ness when reading /etc/ethers. 2.21 broke
1441: this too.
1442:
1443: Fixed wedge with certain DHCP options. Yet another 2.21
1444: regression. Rob Holland and Roy Marples chased this one
1445: down.
1446:
1447: version 2.23
1448: Added a check to ensure that there cannot be more than one
1449: dhcp-host option for any one IP address, even if the
1450: addresses are assigned indirectly via a hostname and
1451: /etc/hosts.
1452:
1453: Include a "server identifier" in DHCPNAK replies, as
1454: required by RFC2131.
1455:
1456: Added method support for DBus
1457: (http://www.freedesktop.org/Software/dbus)
1458: This is a superior way to re-configure dnsmasq on-the-fly
1459: with different upstream nameservers, as the host moves
1460: between networks. DBus support must be enabled in
1461: src/config.h and should be considered experimental at this
1462: point. See DBus-interface for the specification of the
1463: DBus method calls supported.
1464:
1465: Added information to the FAQ about setting the DNS domain
1466: in windows XP and Mac OS X, thanks to Rick Hull.
1467:
1468: Added sanity check to resolv.conf polling code to cope
1469: with backwards-moving clocks. Thanks to Leonardo Canducci
1470: for help with this.
1471:
1472: Handle so-called "A-for-A" queries, which are queries for
1473: the address associated with a name which is already a
1474: dotted-quad address. These should be handled by the
1475: resolver code, but sometimes aren't and there's no point
1476: in forwarding them.
1477:
1478: Added "no-dhcp-interface" option to disable DHCP service
1479: on an interface, whilst still providing DNS.
1480:
1481: Fix format-string problem - config file names get passed
1482: to fprintf as a format string, so % characters could cause
1483: crashes. Thanks to Rob Holland for sleuthing that one.
1484:
1485: Fixed multiple compiler warnings from gcc 4. Thanks to
1486: Tim Cutts for the report.
1487:
1488: Send the hostname option on DHCP offer messages as well as
1489: DHCP ack messages. This is required by the Rio Digital
1490: Audio Receiver. Thanks to Ron Frederick for the patch.
1491:
1492: Add 'd' (for day) as a possible time multiplier in lease
1493: time specifications. Thanks to Michael Deegan.
1494:
1495: Make quoting suppress recognition of IP addresses, so
1496: dhcp-option=66,1.2.3.4 now means something different to
1497: dhcp-option=66,"1.2.3.4", which sets the option to a
1498: string value. Thanks to Brian Macauley for the bug report.
1499:
1500: Fixed the option parsing code to avoid segfaults from some
1501: invalid configurations. Thanks to Wookey for spotting that one.
1502:
1503: Provide information about which compile-time options were
1504: selected, both in the log at startup and as part of the output
1505: from dnsmasq --version. Thanks to Dirk Schenkewitz for
1506: the suggestion.
1507:
1.1.1.2 ! misho 1508: Fix pathological behaviour when a broken client keeps sending
1.1 misho 1509: DHCPDISCOVER messages repeatedly and fast. Because dealing with
1510: each of these takes a few seconds, (because of the ping) then a
1511: queue of DHCP packets could build up. Now, the results of a ping
1512: test are assumed to be valid for 30 seconds, so repeated waits are
1513: not required. Thanks to Luca Landi for finding this.
1514:
1515: Allow DHCPINFORM requests without hardware address
1516: information. These are generated by some browsers, looking
1517: for proxy information. Thanks to Stanley Jaddoe for the
1518: bug report on that.
1519:
1520: Add support of the "client FQDN" DHCP option. If present,
1521: this is used to allow the client to tell dnsmasq its name,
1522: in preference to (mis)using the hostname option. See
1523: http://tools.ietf.org/wg/dhc/draft-ietf-dhc-fqdn-option/\
1524: draft-ietf-dhc-fqdn-option-10.txt
1525: for details of the draft spec.
1526:
1527: Added startup scripts for MacOS X Tiger/Panther to the
1528: contrib collection. Thanks to Tim Cutts.
1529:
1530: Tweak DHCP network selection so that clients which turn up
1531: on our network in REBINDING state and with a lease for a
1532: foreign network will get a NAK response. Thanks to Dan
1533: Shechter for work on this and an initial patch and thanks
1534: to Gyorgy Farkas for further testing.
1535:
1536: Fix DNS query forwarding for empty queries and forward
1537: queries even when the recursion-desired bit is clear. This
1538: allows "dig +trace" to work. Problem report from Uwe
1539: Gansert.
1540:
1541: Added "const" declarations where appropriate, thanks to
1542: Andreas Mohr for the patch.
1543:
1544: Added --bootp-dynamic option and associated
1545: functionality. Thanks to Josef Wolf for the suggestion.
1546:
1547: version 2.24
1548: Updated contrib/openvpn/dnsmasq.patch from Joseph Tate.
1549:
1550: Tweaked DHCP NAK code, a DHCP NAK is now unicast as a
1551: fallback in cases where a broadcast is futile: namely in
1552: response to a unicast REQUEST from a non-local network
1553: which was not sent via a relay.
1554:
1555: Slightly changed the semantics of domain matching in
1556: --server and --address configs. --server=/domain.com/ still
1557: matches domain.com and sub.domain.com but does not
1558: now match newdomain.com The semantics of
1559: --server=/.domain.com/ are unchanged.
1560: Thanks to Chris Blaise for the patch.
1561:
1562: Added backwards-compatible internationalisation support.
1563: The existing make targets, (all, dnsmasq, install) work as
1564: before. New ones (all-i18n, and install-i18n) add gettext.
1565: The translations live in po/ There are not too many
1566: strings, so if anybody can provide translations (and for
1567: the manpage....) please send them in.
1568:
1569: Tweak behaviour on receipt of REFUSED or SERVFAIL rcodes,
1570: now the query gets retried on all servers before returning
1571: the error to the source of the query. Thanks to Javier
1572: Kohen for the report.
1573:
1574: Added Polish translation - thanks to Tomasz Sochanski.
1575:
1576: Changed default manpage install location from /usr/man
1577: to /usr/share/man
1578:
1579: Added Spanish translation - thanks to Christopher Chatham.
1580:
1581: Log a warning when a DHCP packet is truncated due to lack
1582: of space. (Thanks to Michael Welle for the prompt to do
1583: this.)
1584:
1585: Added French translation - thanks to Lionel Tricon.
1586:
1587: Added Indonesian translation - thanks to Salman AS.
1588:
1589: Tweaked the netlink code to cope with interface broadcast
1590: address not set, or set to 0.0.0.0.
1591:
1592: Fixed problem assigning fixed addresses to hosts when more
1593: than one dhcp-range is available. Thanks to Sorin Panca
1594: for help chasing this down.
1595:
1.1.1.2 ! misho 1596: Added more explicit error messages to the hosts file and
1.1 misho 1597: ethers file reading code. Markus Kaiserswerth suffered to
1598: make this happen.
1599:
1600: Ensure that a hostname supplied by a DHCP client can never
1601: override one configured on the server. Previously, any
1602: host claiming a name would be given it, even if that
1603: over-rode a dhcp-host declaration, leading to potentially
1604: confusing situations.
1605:
1606: Added Slackware package-build stuff into contrib/ The i18n
1607: effort broke the current scripts, and working ones were
1608: needed for testing, so they ended up here rather than make
1609: Pat re-invent the wheel.
1610:
1611: Added Romanian translation, thanks to Sorin Panca for
1612: that.
1613:
1614: version 2.25
1615: Fixed RedHat spec file for FC4 - thanks to Werner Hoelzl
1616: and Andrew Bird.
1617:
1618: Fixed Suse spec file - thanks to Steven Springl.
1619:
1.1.1.2 ! misho 1620: Fixed DHCP bug when two distinct subnets are on the same
1.1 misho 1621: physical interface. Thanks to Pawel Zawora for finding
1622: this and suggesting the fix.
1623:
1624: Added logging to make it explicit when dnsmasq falls back
1625: from using RT-netlink sockets to the old ioctl API for
1626: getting information about interfaces. Doing this
1627: completely silently made remote debugging hard.
1628:
1629: Merged uclibc build fixes from the OpenWRT package into
1630: src/config.h
1631:
1632: Added Norwegian translation - thanks to Jan Erik Askildt.
1633:
1634: version 2.26
1635: Fixed SuSe rpm patch problem - thanks to Steven Springl.
1636:
1637: Fixed crash when attempting to send a DHCP NAK to a host
1638: which believes it has a lease on an unknown
1639: network. Thanks to Lutz Pressler for the bug report and
1640: patch.
1641:
1642: version 2.27
1643: Tweaked DHCP behaviour when a client attempts to renew a lease
1644: which dnsmasq doesn't know about. Previously that would always
1645: result in a DHCPNAK. Now, in dhcp-authoritative mode, the
1646: lease will be created, if it's legal. This makes dnsmasq work
1647: better if the lease database is lost, for example on an OpenWRT
1648: system which reboots. Thanks to Stephen Rose for work on
1649: this.
1650:
1651: Added the ability to support RFC-3442 style destination
1652: descriptors in dhcp-options. This makes classless static
1653: routes easy to do, eg dhcp-option=121,192.168.1.0/24,1.2.3.4
1654:
1655: Added error-checking to the code which writes the lease
1656: file. If this fails for any reason, an error is logged,
1657: and a retry occurs after one minute. This should improve
1658: things eg when a filesystem is full. Thanks to Jens Holze
1659: for the bug report.
1660:
1661: Fixed breakage of the "/#/ matches any domain" facility
1662: which happened in 2.24. Thanks to Peter Surda for the bug
1663: report.
1664:
1665: Use "size_t" and "ssize_t" types where appropriate in the
1666: code.
1667:
1668: Fix buggy CNAME handling in mixed IPv4 and IPv6
1669: queries. Thanks to Andreas Pelme for help finding that.
1670:
1671: Added some code to attempt to re-transmit DNS queries when
1672: a network interface comes up. This helps on DoD links,
1673: where frequently the packet which triggers dialling is
1674: a DNS query, which then gets lost. By re-sending, we can
1675: avoid the lookup failing. This function is only active
1676: when netlink support is compiled in, and therefore only
1677: under Linux. Thanks to Jean Wolter for help with this.
1678:
1679: Tweaked the DHCP tag-matching code to work correctly with
1680: NOT-tag conditions. Thanks to Lutz Pressler for finding
1681: the bug.
1682:
1683: Generalised netid-tag matching in dhcp-range statements to
1684: allow more than one tag.
1685:
1686: Added --dhcp-mac to do MAC address matching in the same
1687: way as vendorclass and userclass matching. A good
1688: suggestion from Lutz Pressler.
1689:
1690: Add workaround for buggy early Microsoft DHCP clients
1691: which need zero-termination in string options.
1692: Thanks to Fabiano Pires for help with this.
1693:
1694: Generalised the DHCP code to cope with any hardware
1695: address type, at least on Linux. *BSD is still limited to
1696: ethernet only.
1697:
1698: version 2.28
1699: Eliminated all raw network access when running on
1700: Linux. All DHCP network activity now goes through the IP
1701: stack. Packet sockets are no longer required. Apart from
1702: being a neat hack, this should also allow DHCP over IPsec
1703: to work better. On *BSD and OS X, the old method of raw net
1704: access through BPF is retained.
1705:
1706: Simplified build options. Networking is now slimmed down
1707: to a choice of "linux" or "other". Netlink is always used
1708: under Linux. Since netlink has been available since 2.2
1709: and non-optional in an IPv4-configured kernel since 2.4,
1710: and the dnsmasq netlink code is now well tested, this
1711: should work out fine.
1712:
1713: Removed decayed build support for libc5 and Solaris.
1714:
1715: Removed pselect code: use a pipe for race-free signal
1716: handling instead, as this works everywhere.
1717:
1718: No longer enable the ISC leasefile reading code in the
1719: distributed sources. I doubt there are many people left
1720: using this 1.x compatibility code. Those that are will
1721: have to explicitly enable it in src/config.h.
1722:
1723: Don't send the "DHCP maximum message size" option, even if
1724: requested. RFC2131 says this is a "MUST NOT".
1725:
1726: Support larger-than-minimum DHCP message. Dnsmasq is now
1727: happy to get larger than 576-byte DHCP messages, and will
1728: return large messages, if permitted by the "maximum
1729: message size" option of the message to which it is
1730: replying. There's now an arbitrary sanity limit of 16384
1731: bytes.
1732:
1733: Added --no-ping option. This fixes an RFC2131 "SHOULD".
1734:
1735: Building on the 2.27 MAC-address changes, allow clients to
1736: provide no MAC address at all, relying on the client-id as
1737: a unique identifier. This should make things like DHCP for
1738: USB come easier.
1739:
1740: Fixed regression in netlink code under 2.2.x kernels which
1741: occurred in 2.27. Erik Jan Tromp is the vintage kernel fan
1742: who found this. P.S. It looks like this "netlink bind:
1.1.1.2 ! misho 1743: permission denied" problem occurred in kernels at least as
1.1 misho 1744: late a 2.4.18. Good information from Alain Richoux.
1745:
1746: Added a warning when it's impossible to give a host its
1747: configured address because the address is leased
1748: elsewhere. A sensible suggestion from Mircea Bardac.
1749:
1750: Added minimal support for RFC 3046 DHCP relay agent-id
1751: options. The DHCP server now echoes these back to the
1752: relay, as required by the RFC. Also, RFC 3527 link selection
1753: sub-options are honoured.
1754:
1755: Set the process "dumpable" flag when running in debug
1756: mode: this makes getting core dumps from root processes
1757: much easier.
1758:
1759: Fixed one-byte buffer overflow which seems to only cause
1760: problems when dnsmasq is linked with uclibc. Thanks to
1761: Eric House and Eric Spakman for help in chasing this down.
1762:
1763: Tolerate configuration screwups which lead to the DHCP
1.1.1.2 ! misho 1764: server attempting to allocate its own address to a
1.1 misho 1765: client; eg setting the whole subnet range as a DHCP
1766: range. Addresses in use by the server are now excluded
1767: from use by clients.
1768:
1769: Did some thinking about HAVE_BROKEN_RTC mode, and made it
1770: much simpler and better. The key is to just keep lease
1771: lengths in the lease file. Since these normally never
1772: change, even as the lease is renewed, the lease file never
1773: needs to change except when machines arrive on the network
1774: or leave. This eliminates the code for timed writes, and
1775: reduces the amount of wear on a flash filesystem to the
1776: absolute minimum. Also re-did the basic time function in
1777: this mode to use the portable times(), rather than parsing
1778: /proc/uptime.
1779:
1780: Believe the source port number when replying to unicast
1781: DHCP requests and DHCP requests via a relay, instead of always
1782: using the standard ports. This will allow relays on
1783: non-standard ports and DHCPINFORM from unprivileged ports
1784: to work. The source port sent by unconfigured clients is still
1785: ignored, since this may be unreliable. This means that a DHCP
1786: client must use the standard port to do full configuration.
1787:
1788: version 2.29
1789: Fixed compilation on OpenBSD (thanks to Tom Hensel for the
1790: report).
1791:
1792: Fixed false "no interface" errors when --bind-interfaces is
1793: set along with --interface=lo or --listen-address. Thanks
1794: to Paul Wise for the report.
1795:
1796: Updated patch for SuSE rpm. Thanks to Steven Springl.
1797:
1798: It turns out that there are some Linux kernel
1799: configurations which make using the capability system
1800: impossible. If this situation occurs then continue, running
1801: as root, and log a warning. Thanks to Scott Wehrenberg
1802: for help tracking this down.
1803:
1804: version 2.30
1805: Fixed crash when a DHCP client requested a broadcast
1806: reply. This problem was introduced in version 2.28.
1807: Thanks to Sandra Dekkers for the bug report.
1808:
1809: version 2.31
1810: Added --dhcp-script option. There have been calls for this
1811: for a long time from many good people. Fabio Muzzi gets
1812: the prize for finally convincing me.
1813:
1814: Added example dbus config file and moved dbus stuff into
1815: its own directory.
1816:
1817: Removed horribly outdated Redhat RPM build files. These
1818: are obsolete now that dnsmasq in in Fedora extras. Thanks
1819: to Patrick "Jima" Laughton, the Fedora package
1820: maintainer.
1821:
1822: Added workaround for Linux kernel bug. This manifests
1823: itself as failure of DHCP on kernels with "support for
1824: classical IP over ATM" configured. That includes most
1825: Debian kernel packages. Many thanks to A. Costa and
1826: Benjamin Kudria for their huge efforts in chasing this
1827: down.
1828:
1829: Force-kill child processes when dnsmasq is sent a sigterm,
1830: otherwise an unclosed TCP connection could keep dnsmasq
1831: hanging round for a few minutes.
1832:
1833: Tweaked config.h logic for uclibc build. It will now pick
1834: up MMU and IPV6 status correctly on every system I tested.
1835:
1836: version 2.32
1837: Attempt a better job of replacing previous configuration
1838: when re-reading /etc/hosts and /etc/ethers. SIGHUP is
1839: still not identical to a restart under all circumstances,
1840: but it is for the common case of name->MAC address in
1841: /etc/ethers and name->IP address in /etc/hosts.
1842:
1843: Fall back to broadcast for DHCP to an unconfigured client
1844: when the MAC address size is greater than 14 bytes.
1845:
1846: Fix problem in 2.28-onwards releases which breaks DNS on
1847: Mac OS X. Thanks to Doug Fields for the bug report and
1848: testing.
1849:
1850: Added fix to allow compilation on c89-only compilers.
1851: Thanks to John Mastwijk for the patch.
1852:
1853: Tweak resolv file polling code to work better if there is
1854: a race between updating the mtime and file contents. This
1855: is not normally a problem, but it can be on systems which
1856: replace nameservers whilst active. The code now continues
1857: to read resolv.conf until it gets at least one usable
1858: server. Thanks to Holger Mauermann for help with this.
1859:
1860: If a client DECLINEs an address which is allocated to it
1861: via dhcp-host or /etc/hosts, lock that address out of use
1862: for ten minutes, instead of forever, and log when it's not
1863: being used because of the lock-out. This should provide
1864: less surprising behaviour when a configured address can't be
1865: used. Thanks to Peter Surda and Heinz Deinhart for input
1866: on this.
1867:
1868: Fixed *BSD DHCP breakage with only some
1869: arches/compilers, depending on structure padding rules.
1870: Thanks to Jeb Campbell and Tom Hensel for help with this.
1871:
1872: Added --conf-dir option. Suggestion from Aaron Tygart.
1873:
1874: Applied patch from Brent Cook which allows netids in
1875: dhcp-option configuration lines to be prefixed by
1876: "net:". This is not required by the syntax, but it is
1877: consistent with other configuration items.
1878:
1879: Added --log-facility option. Suggestion from Fabio Muzzi.
1880:
1881: Major update to Spanish translation. Many thanks to Chris
1882: Chatham.
1883:
1884: Fixed gcc-4.1 strict-alias compilation warning.
1885:
1886: version 2.33
1887: Remove bash-specific shellcode from the Makefile.
1888:
1889: Fix breakage with some DHCP relay implementations which
1890: was introduced in 2.28. Believing the source port in
1891: DHCP requests and sending the reply there is sometimes a
1892: bad thing to do, so I've reverted to always sending to
1893: the relay on port 68. Thanks to Daniel Hamlin and Alex
1894: (alde) for bug reports on this.
1895:
1896: Moved the SuSe packaging files to contrib. I will no
1897: longer attempt to maintain this in the source tarball. It
1898: will be done externally, in the same way as packaging for
1899: other distros. Suse packages are available from
1900: ftp://ftp.suse.com/pub/people/ug/
1901:
1902: Merged patch from Gentoo to honour $LDFLAGS environment.
1903:
1904: Fix bug in resolv.conf processing when more than one file
1905: is being checked.
1906:
1907: Add --dns-forward-max option.
1908:
1909: Warn if --resolv-file flags are ignored because of
1910: --no-resolv. Thanks to Martin F Krafft for spotting this
1911: one.
1912:
1913: Add --leasefile-ro option which allows the use of an
1914: external lease database. Many thanks to Steve Horbachuk
1915: for assistance developing this feature.
1916:
1917: Provide extra information to lease-change script via its
1918: environment. If the host has a client-id, then
1919: DNSMASQ_CLIENT_ID will be set. Either the lease length (in
1920: DNSMASQ_LEASE_LENGTH) or lease expiry time (in
1921: DNSMASQ_LEASE_EXPIRES) will be set, depending on the
1922: HAVE_BROKEN_RTC compile-time option. This extra
1923: information should make it possible to maintain the lease
1924: database in external storage such as LDAP or a relational
1925: database. Note that while leasefile-ro is set, the script
1926: will be called with "old" events more often, since
1927: changes to the client-id and lease length
1928: (HAVE_BROKEN_RTC) or lease expiry time (otherwise)
1929: are now flagged.
1930:
1931: Add contrib/wrt/* which is an example implementation of an
1932: external persistent lease database for *WRT distros with
1933: the nvram command.
1934:
1935: Add contrib/wrt/dhcp_release.c which is a small utility
1936: which removes DHCP leases using DHCPRELEASE operation in
1937: the DHCP protocol.
1938:
1939: version 2.34
1940: Tweak network-determination code for another corner case:
1941: in this case a host forced to move between dhcp-ranges on
1942: the same physical interface. Thanks to Matthias Andree.
1943:
1944: Improve handling of high DNS loads by throttling acceptance of
1945: new queries when resources are tight. This should be a
1946: better response than the "forwarding table full..."
1947: message which was logged before.
1948:
1949: Fixed intermittent infinite loop when re-reading
1950: /etc/ethers after SIGHUP. Thanks to Eldon Ziegler for the
1951: bug report.
1952:
1953: Provide extra information to the lease-change script: when
1954: a lease loses its hostname (because a new lease comes
1955: along and claims the same new), the "old" action is called
1956: with the current state of the lease, ie no name. The
1957: change is to provide the former name which the lease had
1958: in the environment variable DNSMASQ_OLD_HOSTNAME. This
1959: helps scripts which do stuff based on hostname, rather
1960: than IP address. Also provide vendor-class and user-class
1961: information to the lease-change script when a new lease is
1962: created in the DNSMASQ_VENDOR_CLASS and
1963: DNSMASQ_USER_CLASS<n> environment variables. Suggestion
1964: from Francois-Xavier Le Bail.
1965:
1966: Run the lease change script as root, even when dnsmasq is
1967: configured to change UID to an unprivileged user. Since
1968: most uses of the lease change script need root, this
1969: allows its use whilst keeping the security advantages of
1970: running the daemon without privs. The script is invoked
1971: via a small helper process which keeps root UID, and
1972: validates all data received from the main process. To get
1973: root, an attacker would have to break dnsmasq and then
1974: break the helper through the restricted comms channel
1975: linking the two.
1976:
1977: Add contrib/port-forward/* which is a script to set up
1978: port-forwards using the DHCP lease-change script. It's
1979: possible to add a host to a config file by name, and when
1980: that host gets a DHCP lease, the script will use iptables
1981: to set up port-forwards to configured ports at the address
1982: which the host is allocated. The script also handles
1983: setting up the port-forward iptables entries after reboot,
1984: using the persistent lease database, and removing them
1985: when a host leaves and its DHCP lease expires.
1986:
1987: Fix unaligned access problem which caused wrong log
1988: messages with some clients on some architectures. Thanks
1989: to Francois-Xavier Le Bail for the bugreport.
1990:
1991: Fixed problem with DHCPRELEASE and multi-address
1992: interfaces. Enhanced contrib/wrt/dhcp_release to cope
1993: under these circumstances too. Thanks to Eldon Ziegler for
1994: input on this.
1995:
1996: Updated French translation: thanks to Gildas Le Nadan.
1997:
1998: Upgraded the name hash function in the DNS cache. Thanks
1999: to Oleg Khovayko for good work on this.
2000:
2001: Added --clear-on-reload flag. Suggestion from Johannes
2002: Stezenbach.
2003:
2004: Treat a nameserver address of 0.0.0.0 as "nothing". Erwin
2005: Cabrera spotted that specifying a nameserver as 0.0.0.0
2006: breaks things badly; this is because the network stack
2007: treats is as "this host" and an endless loop ensues.
2008:
2009: Added Webmin module in contrib/webmin. Thanks to Neil
2010: Fisher for that.
2011:
2012: version 2.35
2013: Generate an "old" script event when a client does a DHCPREQUEST
2014: in INIT-REBOOT or SELECTING state and the lease already
2015: exists. Supply vendor and user class information to these
2016: script calls.
2017:
2018: Added support for Dragonfly BSD to src/config.h
2019:
2020: Removed "Upgrading to 2.0" document, which is ancient
2021: history now.
2022:
2023: Tweak DHCP networking code for BSD, esp OpenBSD. Added a
2024: workaround for a bug in OpenBSD 4.0: there should finally
2025: be support for multiple interfaces under OpenBSD now.
2026: Note that no version of dnsmasq before 2.35 will work for
2027: DHCP under OpenBSD 4.0 because of a kernel bug.
2028: Thanks to Claudio Jeker, Jeb Campbell and Cristobal
2029: Palmer for help with this.
2030:
2031: Optimised the cache code for the case of large
2032: /etc/hosts. This is mainly to remove the O(n-squared)
2033: algorithm which made reading large (50000 lines) files
2034: slow, but it also takes into account the size of
2035: /etc/hosts when building hash tables, so overall
2036: performance should be better. Thanks to "koko" for
2037: pointing out the problem.
2038:
2039: version 2.36
2040: Added --dhcp-ignore-names flag which tells dnsmasq not to
2041: use names provided by DHCP clients. Suggestion from
2042: Thomas M Steenholdt.
2043:
2044: Send netmask and broadcast address DHCP options always,
2045: even if the client doesn't request them. This makes a few
2046: odd clients work better.
2047:
2048: Added simple TFTP function, optimised for net-boot. It is
2049: now possible to net boot hosts using only dnsmasq. The
2050: TFTP server is read-only, binary-mode only, and designed to be
2051: secure; it adds about 4K to the dnsmasq binary.
2052:
2053: Support DHCP option 120, SIP servers, (RFC 3361). Both
2054: encodings are supported, so both --dhcp-option=120,192.168.2.3
2055: and --dhcp-option=120,sip.example.net will work. Brian
2056: Candler pointed out the need for this.
2057:
2058: Allow spaces in domain names, to support DNS-SD.
2059:
2060: Add --ptr-record flag, again for DNS-SD. Thanks to Stephan
2061: Sokolow for the suggestion.
2062:
2063: Tolerate leading space on lines in the config file. Thanks
2064: to Luigi Rizzo for pointing this out.
2065:
2066: Fixed netlink.c to cope with headers from the Linux 2.6.19
2067: kernel. Thanks to Philip Wall for the bug report.
2068:
2069: Added --dhcp-bridge option, but only to the FreeBSD
1.1.1.2 ! misho 2070: build. This fixes an oddity with a particular bridged
1.1 misho 2071: network configuration on FreeBSD. Thanks to Luigi Rizzo
2072: for the patch.
2073:
2074: Added FAQ entry about running dnsmasq in a Linux
2075: vserver. Thanks to Gildas le Nadan for the information.
2076:
2077: Fixed problem with option parsing which interpreted "/" as
2078: an address and not a string. Thanks to Luigi Rizzo
2079: for the patch.
2080:
2081: Ignore the --domain-needed flag when forwarding NS
2082: and SOA queries, since NS queries of TLDs are always legit.
2083: Marcus Better pointed out this problem.
2084:
2085: Take care to forward signed DNS requests bit-perfect, so
2086: as not to affect the validity of the signature. This
2087: should allow DDNS updates to be forwarded.
2088:
2089: version 2.37
2090: Add better support for RFC-2855 DHCP-over-firewire and RFC
2091: -4390 DHCP-over-InfiniBand. A good suggestion from Karl Svec.
2092:
2093: Some efficiency tweaks to the cache code for very large
2094: /etc/hosts files. Should improve reverse (address->name)
2095: lookups and garbage collection. Thanks to Jan 'RedBully'
2096: Seiffert for input on this.
2097:
2098: Fix regression in 2.36 which made bogus-nxdomain
2099: and DNS caching unreliable. Thanks to Dennis DeDonatis
2100: and Jan Seiffert for bug reports.
2101:
2102: Make DHCP encapsulated vendor-class options sane. Be
2103: warned that some conceivable existing configurations
2104: using these may break, but they work in a much
2105: simpler and more logical way now. Prepending
2106: "vendor:<client-id>" to an option encapsulates it
2107: in option 43, and the option is sent only if the
2108: client-supplied vendor-class substring-matches with
2109: the given client-id. Thanks to Dennis DeDonatis for
2110: help with this.
2111:
2112: Apply patch from Jan Seiffert to tidy up tftp.c
2113:
2114: Add support for overloading the filename and servername
2115: fields in DHCP packet. This gives extra option-space when
2116: these fields are not being used or with a modern client
2117: which supports moving them into options.
2118:
2119: Added a LIMITS section to the man-page, with guidance on
2120: maximum numbers of clients, file sizes and tuning.
2121:
2122: release 2.38
2123: Fix compilation on *BSD. Thanks to Tom Hensel.
2124:
2125: Don't send length zero DHCP option 43 and cope with
2126: encapsulated options whose total length exceeds 255 octets
2127: by splitting them into multiple option 43 pieces.
2128:
2129: Avoid queries being retried forever when --strict-order is
2130: set and an upstream server returns a SERVFAIL
2131: error. Thanks to Johannes Stezenbach for spotting this.
2132:
2133: Fix BOOTP support, broken in version 2.37.
2134:
2135: Add example dhcp-options for Etherboot.
2136:
2137: Add \e (for ASCII ESCape) to the set of valid escapes
2138: in config-file strings.
2139:
2140: Added --dhcp-option-force flag and examples in the
2141: configuration file which use this to control PXELinux.
2142:
2143: Added --tftp-no-blocksize option.
2144:
2145: Set netid tag "bootp" when BOOTP (rather than DHCP) is in
2146: use. This makes it easy to customise which options are
2147: sent to BOOTP clients. (BOOTP allows only 64 octets for
2148: options, so it can be necessary to trim things.)
2149:
2150: Fix rare hang in cache code, a 2.37 regression. This
2151: probably needs an infinite DHCP lease and some bad luck to
2152: trigger. Thanks to Detlef Reichelt for bug reports and testing.
2153:
2154: release 2.39
2155: Apply patch from Mike Baker/OpenWRT to ensure that names
2156: like "localhost." in /etc/hosts with trailing period
2157: are treated as fully-qualified.
2158:
2159: Tolerate and ignore spaces around commas in the
2160: configuration file in all circumstances. Note that this
2161: may change the meaning of a few existing config files, for
2162: instance
2163: txt-record=mydomain.com, string
2164: would have a leading space in the string before, and now
2165: will not. To get the old behaviour back, use quotes:
2166: txt-record=mydomain.com," string"
2167:
2168: /a is no longer a valid escape in quoted strings.
2169:
2170: Added symbolic DHCP option names. Instead of
2171: dhcp-option = 3, 1.2.3.4
2172: it is now possible to do
2173: dhcp-option = option:router, 1.2.3.4
2174: To see the list of known DHCP options, use the
2175: command "dnsmasq --help dhcp"
2176: Thanks to Luigi Rizzo for a patch and good work on this.
2177:
2178: Overhauled the log code so that logging can be asynchronous;
2179: dnsmasq then no longer blocks waiting for the syslog() library
2180: call. This is important on systems where syslog
2181: is being used to log over the network (and therefore doing
2182: DNS lookups) and syslog is using dnsmasq as its DNS
2183: server. Having dnsmasq block awaiting syslog under
2184: such circumstances can lead to syslog and dnsmasq
2185: deadlocking. The new behaviour is enabled with a new
2186: --log-async flag, which can also be used to tune the
2187: queue length. Paul Chambers found and diagnosed
2188: this trap for the unwary. He also did much testing of
2189: the solution along with Carlos Carvalho.
2190:
2191: --log-facility can now take a file-name instead of a
2192: facility name. When this is done, dnsmasq logs to the
2193: file and not via syslog. (Failures early in startup,
2194: whilst reading configuration, will still go to syslog,
2195: and syslog is used as a log-of-last-resort if the file
2196: cannot be written.)
2197:
2198: Added --log-dhcp flag. Suggestion from Carlos Carvalho.
2199:
2200: Made BINDIR, MANDIR and LOCALEDIR independently
2201: over-rideable in the makefile. Suggestion from Thomas
2202: Klausner.
2203:
2204: Added 127.0.0.0/8 and 169.254.0.0/16 to the address
2205: ranges affected by --bogus-priv. Thanks to Paul
2206: Chambers for the patch.
2207:
2208: Fixed failure of TFTP server with --listen-address. Thanks
2209: to William Dinkel for the bug report.
2210:
2211: Added --dhcp-circuitid and --dhcp-remoteid for RFC3046
2212: relay agent data matching.
2213:
2214: Added --dhcp-subscrid for RFC3993 subscriber-id relay
2215: agent data matching.
2216:
2217: Correctly garbage-collect connections when upstream
2218: servers go away as a result of DBus transactions.
2219:
2220: Allow absolute paths for TFTP transfers even when
2221: --tftp-root is set, as long as the path matches the root,
2222: so /var/ftp/myfile is OK with tftp-root=/var/ftp.
2223: Thanks for Thomas Mizzi for the patch.
2224:
2225: Updated Spanish translation - thanks to Chris Chatham.
2226:
2227: Updated French translation - thanks to Gildas Le Nadan.
2228:
2229: Added to example conf file example of routing PTR queries
2230: for a subnet to a different nameserver. Suggestion from
2231: Jon Nicholson.
2232:
2233: Added --interface-name option. This provides a facility
2234: to add a domain name with a dynamic IP address taken from
2235: the address of a local network interface. Useful for
2236: networks with dynamic IPs.
2237:
2238: version 2.40
2239: Make SIGUSR2 close-and-reopen the logfile when logging
2240: direct to a file. Thanks to Carlos Carvalho for
2241: suggesting this. When a logfile is created, change
2242: its ownership to the user dnsmasq will run as, don't
2243: leave it owned by root.
2244:
2245: Set a special tag, "known" for hosts which are matched by
2246: a dhcp-host or /etc/ethers line. This is especially
2247: useful to be able to do --dhcp-ignore=#known, like ISCs
2248: "deny unknown-clients".
2249:
2250: Explicitly set a umask before creating the leases file,
2251: rather than relying on whatever we inherited. The
2252: permissions are set to 644.
2253:
2254: Fix handling of fully-qualified names in --dhcp-host
2255: directives and in /etc/ethers. These are now rejected
2256: if the domain doesn't match that given by --domain,
2257: and used correctly otherwise. Before, putting
2258: a FQDN here could cause the whole FQDN to be used as
2259: hostname. Thanks to Michael Heimpold for the bug report.
2260:
2261: Massive but trivial edit to make the "daemon" variable
2262: global, instead of copying the same value around as the
2263: first argument to half the functions in the program.
2264:
2265: Updated Spanish manpage and message catalog. Thanks
2266: to Chris Chatham.
2267:
2268: Added patch for support of DNS LOC records in
2269: contrib/dns-loc. Thanks to Lorenz Schori.
2270:
2271: Fixed error in manpage: dhcp-ignore-name ->
2272: dhcp-ignore-names. Thanks to Daniel Mentz for spotting
2273: this.
2274:
2275: Use client-id as hash-seed for DHCP address allocation
1.1.1.2 ! misho 2276: with Firewire and InfiniBand, as these don't supply a MAC
1.1 misho 2277: address.
2278:
2279: Tweaked TFTP file-open code to make it behave sensibly
2280: when the filesystem changes under its feet.
2281:
2282: Added DNSMASQ_TIME_REMAINING environment variable to the
2283: lease-script.
2284:
2285: Always send replies to DHCPINFORM requests to the source
2286: of the request and not to the address in ciaddr. This
2287: allows third-party queries.
2288:
2289: Return "lease time remaining" in the reply to a DHCPINFORM
2290: request if there exists a lease for the host sending the
2291: request.
2292:
2293: Added --dhcp-hostsfile option. This gives a superset of
2294: the functionality provided by /etc/ethers. Thanks to
2295: Greg Kurtzer for the suggestion.
2296:
2297: Accept keyword "server" as a synonym for "nameserver" in
2298: resolv.conf. Thanks to Andrew Bartlett for the report.
2299:
2300: Add --tftp-unique-root option. Suggestion from Dermot
2301: Bradley.
2302:
2303: Tweak TFTP retry timer to avoid problems with difficult
2304: clients. Thanks to Dermot Bradley for assistance with
2305: this.
2306:
2307: Continue to use unqualified hostnames provided by DHCP
2308: clients, even if the domain part is illegal. (The domain
2309: is ignored, and an error logged.) Previously in this
1.1.1.2 ! misho 2310: situation, the whole name would have been
1.1 misho 2311: rejected. Thanks to Jima for the patch.
2312:
2313: Handle EINTR returns from wait() correctly and reap
2314: our children's children if necessary. This fixes
2315: a problem with zombie-creation under *BSD when using
2316: --dhcp-script.
2317:
2318: Escape spaces in hostnames when they are stored in the
2319: leases file and passed to the lease-change
2320: script. Suggestion from Ben Voigt.
2321:
1.1.1.2 ! misho 2322: Re-run the lease change script with an "old" event for
1.1 misho 2323: each lease when dnsmasq receives a SIGHUP.
2324:
2325: Added more useful exit codes, including passing on a
2326: non-zero exit code from the lease-script "init" call when
2327: --leasefile-ro is set.
2328:
2329: Log memory allocation failure whilst the daemon is
2330: running. Allocation failures during startup are fatal,
2331: but lack of memory whilst running is worked around.
2332: This used to be silent, but now is logged.
2333:
2334: Fixed misaligned memory access which caused problems on
2335: Blackfin CPUs. Thanks to Alex Landau for the patch.
2336:
2337: Don't include (useless) script-calling code when NO_FORK
2338: is set. Since this tends to be used on very small uclinux
2339: systems, it's worth-while to save some code-size.
2340:
2341: Don't set REUSEADDR on TFTP listening socket. There's no
2342: need to do so, and it creates confusing behaviour when
2343: inetd is also listening on the same port. Thanks to Erik
2344: Brown for spotting the problem.
2345:
2346: version 2.41
2347: Remove deprecated calls when compiled against libdbus 1.1.
2348:
2349: Fix "strict-alias" warning in bpf.c
2350:
2351: Reduce dependency on Gnu-make in build system: dnsmasq now
2352: builds with system make under OpenBSD.
2353:
2354: Port to Solaris. Dnsmasq 1.x used to run under Solaris,
2355: and this release does so again, for Solaris 9 or better.
2356:
2357: Allow the DNS function to be completely disabled, by
2358: setting the port to zero "--port=0". The allows dnsmasq to
2359: be used as a simple DHCP server, simple TFTP server, or
2360: both, but without the DNS server getting in the way.
2361:
2362: Fix a bug where NXDOMAIN could be returned for a query
2363: even if the name's value was known for a different query
2364: type. This bug could be prodded with
2365: --local=/domain/ --address=/name.domain/1.2.3.4
2366: An IPv6 query for name.domain would return NXDOMAIN, and
2367: not the correct NOERROR. Thanks to Lars Nooden for
2368: spotting the bug and Jima for diagnosis of the problem.
2369:
2370: Added per-server stats to the information logged when
2371: dnsmasq gets SIGUSR1.
2372:
2373: Added counts of queries forwarded and queries answered
2374: locally (from the cache, /etc/hosts or config).
2375:
2376: Fixed possible crash bug in DBus IPv6 code. Thanks to Matt
2377: Domsch and Jima.
2378:
2379: Tighten checks for clashes between hosts-file and
2380: DHCP-derived names. Multiple addresses associated with a
2381: name in hosts-file no longer confuses the check.
2382:
2383: Add --dhcp-no-override option to fix problems with some
2384: combinations of stage zero and stage one
2385: bootloaders. Thanks to Steve Alexander for the bug report.
2386:
2387: Add --tftp-port-range option. Thanks to Daniel Mierswa for
2388: the suggestion.
2389:
2390: Add --stop-dns-rebind option. Thanks to Collin Mulliner
2391: for the patch.
2392:
2393: Added GPL version 3 as a license option.
2394:
2395: Added --all-servers option. Thanks to Peter Naulls for the
2396: patch.
2397:
2398: Extend source address mechanism so that the interface used
2399: to contact an upstream DNS server can be nailed
2400: down. Something like "--server=1.2.3.4@eth1" will force
2401: the use of eth1 for traffic to DNS-server 1.2.3.4. This
2402: facility is only available on Linux and Solaris. Thanks to
2403: Peter Naulls for prompting this.
2404:
2405: Add --dhcp-optsfile option. Thanks to Carlos Carvalho for
2406: the suggestion.
2407:
2408: Fixed failure to set source address for server connections
2409: when using TCP. Thanks to Simon Capper for finding this
2410: bug.
2411:
2412: Refuse to give a DHCP client the address it asks for if
2413: the address range in question is not available to that
2414: particular host. Thanks to Cedric Duval for the bug
2415: report.
2416:
2417: Changed behavior of DHCP server to always return total length of
2418: a new lease in DHCPOFFER, even if an existing lease
2419: exists. (It used to return the time remaining on the lease
1.1.1.2 ! misho 2420: when one existed.) This fixes problems with the Sony Ericsson
1.1 misho 2421: K610i phone. Thanks to Hakon Stordahl for finding and
2422: fixing this.
2423:
2424: Add DNSMASQ_INTERFACE to the environment of the
2425: lease-change script. Thanks to Nikos Mavrogiannopoulos for
2426: the patch.
2427:
2428: Fixed broken --alias functionality. Thanks to Michael
2429: Meelis for the bug report.
2430:
2431: Added French translation of the man page. Thank to Gildas
2432: Le Nadan for that.
2433:
2434: Add --dhcp-match flag, to check for arbitrary options in
2435: DHCP messages from clients. This enables use of dnsmasq
1.1.1.2 ! misho 2436: with iPXE. Thanks to Rance Hall for the suggestion.
1.1 misho 2437:
2438: Added --dhcp-broadcast, to force broadcast replies to DHCP
2439: clients which need them but are too dumb or too old to
2440: ask. Thanks to Bodo Bellut for the suggestion.
2441:
2442: Disable path-MTU discovery on DHCP and TFTP sockets. This
2443: is never needed, and the presence of DF flags in the IP
2444: header confuses some broken PXE ROMS. Thanks again to Bodo
2445: Bellut for spotting this.
2446:
2447: Fix problems with addresses which have multiple PTR
2448: records - all but one of these could get lost.
2449:
2450: Fix bug with --address and ANY query type seeing REFUSED
2451: return code in replies. Thanks to Mike Wright for spotting
2452: the problem.
2453:
2454: Update Spanish translation. Thanks to Chris Chatham.
2455:
2456: Add --neg-ttl option.
2457:
2458: Add warnings about the bad effects of --filterwin2k on
2459: SIP, XMPP and Google-talk to the example config file.
2460:
2461: Fix va_list abuse in log.c. This fixes crashes on powerpc
2462: when debug mode is set. Thanks to Cedric Duval for the
2463: patch.
2464:
2465: version 2.42
2466: Define _GNU_SOURCE to avoid problems with later glibc
2467: headers. Thanks to Jima for spotting the problem.
2468:
2469: Add --dhcp-alternate-port option. Thanks to Jan Psota for
2470: the suggestion.
2471:
2472: Fix typo in code which is only used on BSD, when Dbus and
2473: IPv6 support is enabled. Thanks to Roy Marples.
2474:
2475: Updated Polish translations - thank to Jan Psota.
2476:
2477: Fix OS detection logic to cope with GNU/FreeBSD.
2478:
1.1.1.2 ! misho 2479: Fix uninitialised variable in DBus code - thanks to Roy
1.1 misho 2480: Marples.
2481:
2482: Fix network enumeration code to work on later NetBSD -
2483: thanks to Roy Marples.
2484:
2485: Provide --dhcp-bridge on all BSD variants.
2486:
2487: Define _LARGEFILE_SOURCE which removes an arbitrary 2GB
2488: limit on logfiles. Thanks to Paul Chambers for spotting
2489: the problem.
2490:
2491: Fix RFC3046 agent-id echo code, broken for many
2492: releases. Thanks to Jeremy Laine for spotting the problem
2493: and providing a patch.
2494:
2495: Added Solaris 10 service manifest from David Connelly in
2496: contrib/Solaris10
2497:
2498: Add --dhcp-scriptuser option.
2499:
2500: Support new capability interface on suitable Linux
2501: kernels, removes "legacy support in use" messages. Thanks
2502: to Jorge Bastos for pointing this out.
2503:
2504: Fix subtle bug in cache code which could cause dnsmasq to
2505: lock spinning CPU in rare circumstances. Thanks to Alex
2506: Chekholko for bug reports and help debugging.
2507:
2508: Support netascii transfer mode for TFTP.
2509:
