Annotation of embedaddon/dnsmasq/CHANGELOG.archive, revision 1.1
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:
! 59: release 0.96 Fixed embarrasing thinko in cache linked-list code.
! 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.
! 81: (8) Fixed getopt code to work on compliers with unsigned char.
! 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:
! 91: Fixed cacheing of CNAMEs. Previously, a CNAME which pointed
! 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
! 194: ip6.int and ip6.arpa domains are suppored. Dnsmasq can
! 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:
! 217: release 1.4 Fix a bug with DHPC lease parsing which broke in
! 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:
! 261: 1) Drop supplimentary groups.
! 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
! 300: embeded routers, and that's the point really. Thanks to
! 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
! 322: accessable for any reason, as suggested by Hinrich Eilts.
! 323:
! 324: Fixed wrong address printing in error message about
! 325: no interface with address.
! 326:
! 327: Updated docs and split installation instuctions into setup.html.
! 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
! 349: specfic servers. Suggested by Jens Vonderheide.
! 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
! 389: DHCP which stops anthing else caching these
! 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:
! 395: Extended HAVE_IPV6 config flag to allow compliation on
! 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:
! 474: Check that recieved queries have only rfc1035-legal characters
! 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:
! 552: Fixed name-comparision routines to not depend on Locale,
! 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:
! 577: Add code to return the software version in repsonse to the
! 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
! 638: IP adresses where the correct one will be selected for
! 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:
! 677: Allow empty DHCP options, like so: dhpc-option=44
! 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:
! 748: Return DHCP T1 and T2 times, with "fuzz" to desychronise lease
! 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
! 841: characters. Qudos to Dag Wieers for hepling to nail that
! 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
! 978: are searched on them all. (2) matches agains vendor class
! 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
! 1000: reffered to above. Also, if a client sends a hostname when
! 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
! 1013: causes a fatal error on startup rather than an huge
! 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
! 1022: then becomes prefered for the next query. This should
! 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
! 1030: verions of *BSD seem to have enough stuff in the header
! 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:
! 1052: Add back fatal errors when nonexistant
! 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
! 1196: names. We now return a NODATA reponse for names which are
! 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
! 1232: occured when corrupted packets were received. Thanks to
! 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:
! 1300: Fix problems which occured when more than one dhcp-range
! 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
! 1317: zero length client-id, in particluar, could seriously
! 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
! 1392: use. Thanks to Will Murnane for the bug report and
! 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:
! 1508: Fix pathalogical behaviour when a broken client keeps sending
! 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:
! 1596: Added more explict error mesages to the hosts file and
! 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:
! 1620: Fixed DHCP bug when two distict subnets are on the same
! 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:
! 1743: permission denied" problem occured in kernels at least as
! 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
! 1764: server attemping to allocate its own address to a
! 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
! 2070: build. This fixes an oddity with a a particular bridged
! 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
! 2276: with Firewire and Infiniband, as these don't supply an MAC
! 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
! 2310: situation, the whole name whould have been
! 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:
! 2322: Re-run the lease chamge script with an "old" event for
! 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

! 2405: Add --dhcp-optsfile option. Thanks to Carlos Carvalho for
! 2406: the suggestion.
! 2407:
! 2408: Fixed failure to set source address for server connections

! 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

! 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
! 2420: whne one existed.) This fixes problems with the Sony Ericsson
