2 Fix reversion on 2.74 which caused 100% CPU use when a
3 dhcp-script is configured. Thanks to Adrian Davey for
4 reporting the bug and testing the fix.
8 Fix reversion in 2.73 where --conf-file would attempt to
9 read the default file, rather than no file.
11 Fix inotify code to handle dangling symlinks better and
12 not SEGV in some circumstances.
14 DNSSEC fix. In the case of a signed CNAME generated by a
15 wildcard which pointed to an unsigned domain, the wrong
16 status would be logged, and some necessary checks omitted.
20 Fix crash at startup when an empty suffix is supplied to
21 --conf-dir, also trivial memory leak. Thanks to
22 Tomas Hozza for spotting this.
24 Remove floor of 4096 on advertised EDNS0 packet size when
25 DNSSEC in use, the original rationale for this has long gone.
26 Thanks to Anders Kaseorg for spotting this.
28 Use inotify for checking on updates to /etc/resolv.conf and
29 friends under Linux. This fixes race conditions when the files are
30 updated rapidly and saves CPU by noy polling. To build
31 a binary that runs on old Linux kernels without inotify,
32 use make COPTS=-DNO_INOTIFY
34 Fix breakage of --domain=<domain>,<subnet>,local - only reverse
35 queries were intercepted. THis appears to have been broken
36 since 2.69. Thanks to Josh Stone for finding the bug.
38 Eliminate IPv6 privacy addresses and deprecated addresses from
39 the answers given by --interface-name. Note that reverse queries
40 (ie looking for names, given addresses) are not affected.
41 Thanks to Michael Gorbach for the suggestion.
43 Fix crash in DNSSEC code with long RRs. Thanks to Marco Davids
46 Add --ignore-address option. Ignore replies to A-record
47 queries which include the specified address. No error is
48 generated, dnsmasq simply continues to listen for another
49 reply. This is useful to defeat blocking strategies which
50 rely on quickly supplying a forged answer to a DNS
51 request for certain domains, before the correct answer can
52 arrive. Thanks to Glen Huang for the patch.
54 Revisit the part of DNSSEC validation which determines if an
55 unsigned answer is legit, or is in some part of the DNS
56 tree which should be signed. Dnsmasq now works from the
57 DNS root downward looking for the limit of signed
58 delegations, rather than working bottom up. This is
59 both more correct, and less likely to trip over broken
60 nameservers in the unsigned parts of the DNS tree
61 which don't respond well to DNSSEC queries.
63 Add --log-queries=extra option, which makes logs easier
64 to search automatically.
66 Add --min-cache-ttl option. I've resisted this for a long
67 time, on the grounds that disbelieving TTLs is never a
68 good idea, but I've been persuaded that there are
69 sometimes reasons to do it. (Step forward, GFW).
70 To avoid misuse, there's a hard limit on the TTL
71 floor of one hour. Thansk to RinSatsuki for the patch.
73 Cope with multiple interfaces with the same link-local
74 address. (IPv6 addresses are scoped, so this is allowed.)
75 Thanks to Cory Benfield for help with this.
77 Add --dhcp-hostsdir. This allows addition of new host
78 configurations to a running dnsmasq instance much more
79 cheaply than having dnsmasq re-read all its existing
80 configuration each time.
82 Don't reply to DHCPv6 SOLICIT messages if we're not
83 configured to do stateful DHCPv6. Thanks to Win King Wan
86 Fix broken DNSSEC validation of ECDSA signatures.
88 Add --dnssec-timestamp option, which provides an automatic
89 way to detect when the system time becomes valid after
90 boot on systems without an RTC, whilst allowing DNS
91 queries before the clock is valid so that NTP can run.
92 Thanks to Kevin Darbyshire-Bryant for developing this idea.
94 Add --tftp-no-fail option. Thanks to Stefan Tomanek for
97 Fix crash caused by looking up servers.bind, CHAOS text
98 record, when more than about five --servers= lines are
99 in the dnsmasq config. This causes memory corruption
100 which causes a crash later. Thanks to Matt Coddington for
101 sterling work chasing this down.
103 Fix crash on receipt of certain malformed DNS requests.
104 Thanks to Nick Sampanis for spotting the problem.
105 Note that this is could allow the dnsmasq process's
106 memory to be read by an attacker under certain
107 circumstances, so it has a CVE, CVE-2015-3294
109 Fix crash in authoritative DNS code, if a .arpa zone
110 is declared as authoritative, and then a PTR query which
111 is not to be treated as authoritative arrived. Normally,
112 directly declaring .arpa zone as authoritative is not
113 done, so this crash wouldn't be seen. Instead the
114 relevant .arpa zone should be specified as a subnet
115 in the auth-zone declaration. Thanks to Johnny S. Lee
116 for the bugreport and initial patch.
118 Fix authoritative DNS code to correctly reply to NS
119 and SOA queries for .arpa zones for which we are
120 declared authoritative by means of a subnet in auth-zone.
121 Previously we provided correct answers to PTR queries
122 in such zones (including NS and SOA) but not direct
123 NS and SOA queries. Thanks to Johnny S. Lee for
124 pointing out the problem.
126 Fix logging of DHCPREPLY which should be suppressed
127 by quiet-dhcp6. Thanks to J. Pablo Abonia for
128 spotting the problem.
130 Try and handle net connections with broken fragmentation
131 that lose large UDP packets. If a server times out,
132 reduce the maximum UDP packet size field in the EDNS0
133 header to 1280 bytes. If it then answers, make that
136 Check IPv4-mapped IPv6 addresses when --stop-rebind
137 is active. Thanks to Jordan Milne for spotting this.
139 Allow DHCPv4 options T1 and T2 to be set using --dhcp-option.
140 Thanks to Kevin Benton for patches and work on this.
142 Fix code for DHCPCONFIRM DHCPv6 messages to confirm addresses
143 in the correct subnet, even of not in dynamic address
144 allocation range. Thanks to Steve Hirsch for spotting
147 Add AddDhcpLease and DeleteDhcpLease DBus methods. Thanks
148 to Nicolas Cavallari for the patch.
150 Allow configuration of router advertisements without the
151 "on-link" bit set. Thanks to Neil Jerram for the patch.
153 Extend --bridge-interface to DHCPv6 and router
154 advertisements. Thanks to Neil Jerram for the patch.
158 Add ra-advrouter mode, for RFC-3775 mobile IPv6 support.
160 Add support for "ipsets" in *BSD, using pf. Thanks to
161 Sven Falempim for the patch.
163 Fix race condition which could lock up dnsmasq when an
164 interface goes down and up rapidly. Thanks to Conrad
165 Kostecki for helping to chase this down.
167 Add DBus methods SetFilterWin2KOption and SetBogusPrivOption
168 Thanks to the Smoothwall project for the patch.
170 Fix failure to build against Nettle-3.0. Thanks to Steven
171 Barth for spotting this and finding the fix.
173 When assigning existing DHCP leases to intefaces by comparing
174 networks, handle the case that two or more interfaces have the
175 same network part, but different prefix lengths (favour the
176 longer prefix length.) Thanks to Lung-Pin Chang for the
179 Add a mode which detects and removes DNS forwarding loops, ie
180 a query sent to an upstream server returns as a new query to
181 dnsmasq, and would therefore be forwarded again, resulting in
182 a query which loops many times before being dropped. Upstream
183 servers which loop back are disabled and this event is logged.
184 Thanks to Smoothwall for their sponsorship of this feature.
186 Extend --conf-dir to allow filtering of files. So
187 --conf-dir=/etc/dnsmasq.d,\*.conf
188 will load all the files in /etc/dnsmasq.d which end in .conf
190 Fix bug when resulted in NXDOMAIN answers instead of NODATA in
193 Fix bug which caused dnsmasq to become unresponsive if it
194 failed to send packets due to a network interface disappearing.
195 Thanks to Niels Peen for spotting this.
197 Fix problem with --local-service option on big-endian platforms
198 Thanks to Richard Genoud for the patch.
202 Subtle change to error handling to help DNSSEC validation
203 when servers fail to provide NODATA answers for
204 non-existent DS records.
206 Tweak code which removes DNSSEC records from answers when
207 not required. Fixes broken answers when additional section
208 has real records in it. Thanks to Marco Davids for the bug
211 Fix DNSSEC validation of ANY queries. Thanks to Marco Davids
212 for spotting that too.
214 Fix total DNS failure and 100% CPU use if cachesize set to zero,
215 regression introduced in 2.69. Thanks to James Hunt and
216 the Ubuntu crowd for assistance in fixing this.
220 Fix crash, introduced in 2.69, on TCP request when dnsmasq
221 compiled with DNSSEC support, but running without DNSSEC
222 enabled. Thanks to Manish Sing for spotting that one.
224 Fix regression which broke ipset functionality. Thanks to
225 Wang Jian for the bug report.
229 Implement dynamic interface discovery on *BSD. This allows
230 the contructor: syntax to be used in dhcp-range for DHCPv6
231 on the BSD platform. Thanks to Matthias Andree for
232 valuable research on how to implement this.
234 Fix infinite loop associated with some --bogus-nxdomain
235 configs. Thanks fogobogo for the bug report.
237 Fix missing RA RDNS option with configuration like
238 --dhcp-option=option6:23,[::] Thanks to Tsachi Kimeldorfer
239 for spotting the problem.
241 Add [fd00::] and [fe80::] as special addresses in DHCPv6
242 options, analogous to [::]. [fd00::] is replaced with the
243 actual ULA of the interface on the machine running
244 dnsmasq, [fe80::] with the link-local address.
245 Thanks to Tsachi Kimeldorfer for championing this.
247 DNSSEC validation and caching. Dnsmasq needs to be
248 compiled with this enabled, with
250 make dnsmasq COPTS=-DHAVE_DNSSEC
252 this add dependencies on the nettle crypto library and the
253 gmp maths library. It's possible to have these linked
256 make dnsmasq COPTS='-DHAVE_DNSSEC -DHAVE_DNSSEC_STATIC'
258 which bloats the dnsmasq binary, but saves the size of
259 the shared libraries which are much bigger.
261 To enable, DNSSEC, you will need a set of
262 trust-anchors. Now that the TLDs are signed, this can be
263 the keys for the root zone, and for convenience they are
264 included in trust-anchors.conf in the dnsmasq
265 distribution. You should of course check that these are
266 legitimate and up-to-date. So, adding
268 conf-file=/path/to/trust-anchors.conf
271 to your config is all thats needed to get things
272 working. The upstream nameservers have to be DNSSEC-capable
273 too, of course. Many ISP nameservers aren't, but the
274 Google public nameservers (8.8.8.8 and 8.8.4.4) are.
275 When DNSSEC is configured, dnsmasq validates any queries
276 for domains which are signed. Query results which are
277 bogus are replaced with SERVFAIL replies, and results
278 which are correctly signed have the AD bit set. In
279 addition, and just as importantly, dnsmasq supplies
280 correct DNSSEC information to clients which are doing
281 their own validation, and caches DNSKEY, DS and RRSIG
282 records, which significantly improve the performance of
283 downstream validators. Setting --log-queries will show
286 If a domain is returned from an upstream nameserver without
287 DNSSEC signature, dnsmasq by default trusts this. This
288 means that for unsigned zone (still the majority) there
289 is effectively no cost for having DNSSEC enabled. Of course
290 this allows an attacker to replace a signed record with a
291 false unsigned record. This is addressed by the
292 --dnssec-check-unsigned flag, which instructs dnsmasq
293 to prove that an unsigned record is legitimate, by finding
294 a secure proof that the zone containing the record is not
295 signed. Doing this has costs (typically one or two extra
296 upstream queries). It also has a nasty failure mode if
297 dnsmasq's upstream nameservers are not DNSSEC capable.
298 Without --dnssec-check-unsigned using such an upstream
299 server will simply result in not queries being validated;
300 with --dnssec-check-unsigned enabled and a
301 DNSSEC-ignorant upstream server, _all_ queries will fail.
303 Note that DNSSEC requires that the local time is valid and
304 accurate, if not then DNSSEC validation will fail. NTP
305 should be running. This presents a problem for routers
306 without a battery-backed clock. To set the time needs NTP
307 to do DNS lookups, but lookups will fail until NTP has run.
308 To address this, there's a flag, --dnssec-no-timecheck
309 which disables the time checks (only) in DNSSEC. When dnsmasq
310 is started and the clock is not synced, this flag should
311 be used. As soon as the clock is synced, SIGHUP dnsmasq.
312 The SIGHUP clears the cache of partially-validated data and
313 resets the no-timecheck flag, so that all DNSSEC checks
314 henceforward will be complete.
316 The development of DNSSEC in dnsmasq was started by
317 Giovanni Bajo, to whom huge thanks are owed. It has been
318 supported by Comcast, whose techfund grant has allowed for
319 an invaluable period of full-time work to get it to
322 Add --rev-server. Thanks to Dave Taht for suggesting this.
324 Add --servers-file. Allows dynamic update of upstream servers
325 full access to configuration.
327 Add --local-service. Accept DNS queries only from hosts
328 whose address is on a local subnet, ie a subnet for which
329 an interface exists on the server. This option
330 only has effect if there are no --interface --except-interface,
331 --listen-address or --auth-server options. It is intended
332 to be set as a default on installation, to allow
333 unconfigured installations to be useful but also safe from
334 being used for DNS amplification attacks.
336 Fix crashes in cache_get_cname_target() when dangling CNAMEs
337 encountered. Thanks to Andy and the rt-n56u project for
338 find this and helping to chase it down.
340 Fix wrong RCODE in authoritative DNS replies to PTR queries. The
341 correct answer was included, but the RCODE was set to NXDOMAIN.
342 Thanks to Craig McQueen for spotting this.
344 Make statistics available as DNS queries in the .bind TLD as
345 well as logging them.
349 Use random addresses for DHCPv6 temporary address
350 allocations, instead of algorithmically determined stable
353 Fix bug which meant that the DHCPv6 DUID was not available
354 in DHCP script runs during the lifetime of the dnsmasq
355 process which created the DUID de-novo. Once the DUID was
356 created and stored in the lease file and dnsmasq
357 restarted, this bug disappeared.
359 Fix bug introduced in 2.67 which could result in erroneous
360 NXDOMAIN returns to CNAME queries.
362 Fix build failures on MacOS X and openBSD.
364 Allow subnet specifications in --auth-zone to be interface
365 names as well as address literals. This makes it possible
366 to configure authoritative DNS when local address ranges
367 are dynamic and works much better than the previous
368 work-around which exempted contructed DHCP ranges from the
369 IP address filtering. As a consequence, that work-around
370 is removed. Under certain circumstances, this change wil
371 break existing configuration: if you're relying on the
372 contructed-range exception, you need to change --auth-zone
373 to specify the same interface as is used to construct your
374 DHCP ranges, probably with a trailing "/6" like this:
375 --auth-zone=example.com,eth0/6 to limit the addresses to
376 IPv6 addresses of eth0.
378 Fix problems when advertising deleted IPv6 prefixes. If
379 the prefix is deleted (rather than replaced), it doesn't
380 get advertised with zero preferred time. Thanks to Tsachi
383 Fix segfault with some locally configured CNAMEs. Thanks
384 to Andrew Childs for spotting the problem.
386 Fix memory leak on re-reading /etc/hosts and friends,
389 Check the arrival interface of incoming DNS and TFTP
390 requests via IPv6, even in --bind-interfaces mode. This
391 isn't possible for IPv4 and can generate scary warnings,
392 but as it's always possible for IPv6 (the API always
393 exists) then we should do it always.
395 Tweak the rules on prefix-lengths in --dhcp-range for
396 IPv6. The new rule is that the specified prefix length
397 must be larger than or equal to the prefix length of the
398 corresponding address on the local interface.
402 Fix crash if upstream server returns SERVFAIL when
403 --conntrack in use. Thanks to Giacomo Tazzari for finding
404 this and supplying the patch.
406 Repair regression in 2.64. That release stopped sending
407 lease-time information in the reply to DHCPINFORM
408 requests, on the correct grounds that it was a standards
409 violation. However, this broke the dnsmasq-specific
410 dhcp_lease_time utility. Now, DHCPINFORM returns
411 lease-time only if it's specifically requested
412 (maintaining standards) and the dhcp_lease_time utility
413 has been taught to ask for it (restoring functionality).
415 Fix --dhcp-match, --dhcp-vendorclass and --dhcp-userclass
416 to work with BOOTP and well as DHCP. Thanks to Peter
417 Korsgaard for spotting the problem.
419 Add --synth-domain. Thanks to Vishvananda Ishaya for
422 Fix failure to compile ipset.c if old kernel headers are
423 in use. Thanks to Eugene Rudoy for pointing this out.
425 Handle IPv4 interface-address labels in Linux. These are
426 often used to emulate the old IP-alias addresses. Before,
427 using --interface=eth0 would service all the addresses of
428 eth0, including ones configured as aliases, which appear
429 in ifconfig as eth0:0. Now, only addresses with the label
430 eth0 are active. This is not backwards compatible: if you
431 want to continue to bind the aliases too, you need to add
432 eg. --interface=eth0:0 to the config.
434 Fix "failed to set SO_BINDTODEVICE on DHCP socket: Socket
435 operation on non-socket" error on startup with
436 configurations which have exactly one --interface option
437 and do RA but _not_ DHCPv6. Thanks to Trever Adams for the
440 Generalise --interface-name to cope with IPv6 addresses
441 and multiple addresses per interface per address family.
443 Fix option parsing for --dhcp-host, which was generating a
444 spurious error when all seven possible items were
445 included. Thanks to Zhiqiang Wang for the bug report.
447 Remove restriction on prefix-length in --auth-zone. Thanks
448 to Toke Hoiland-Jorgensen for suggesting this.
450 Log when the maximum number of concurrent DNS queries is
451 reached. Thanks to Marcelo Salhab Brogliato for the patch.
453 If wildcards are used in --interface, don't assume that
454 there will only ever be one available interface for DHCP
455 just because there is one at start-up. More may appear, so
456 we can't use SO_BINDTODEVICE. Thanks to Natrio for the bug
459 Increase timeout/number of retries in TFTP to accomodate
460 AudioCodes Voice Gateways doing streaming writes to flash.
461 Thanks to Damian Kaczkowski for spotting the problem.
463 Fix crash with empty DHCP string options when adding zero
464 terminator. Thanks to Patrick McLean for the bug report.
466 Allow hostnames to start with a number, as allowed in
467 RFC-1123. Thanks to Kyle Mestery for the patch.
469 Fixes to DHCP FQDN option handling: don't terminate FQDN
470 if domain not known and allow a FQDN option with blank
471 name to request that a FQDN option is returned in the
472 reply. Thanks to Roy Marples for the patch.
474 Make --clear-on-reload apply to setting upstream servers
477 When the address which triggered the construction of an
478 advertised IPv6 prefix disappears, continue to advertise
479 the prefix for up to 2 hours, with the preferred lifetime
480 set to zero. This satisfies RFC 6204 4.3 L-13 and makes
481 things work better if a prefix disappears without being
482 deprecated first. Thanks to Uwe Schindler for persuasively
485 Fix MAC address enumeration on *BSD. Thanks to Brad Smith
488 Support RFC-4242 information-refresh-time options in the
489 reply to DHCPv6 information-request. The lease time of the
490 smallest valid dhcp-range is sent. Thanks to Uwe Schindler
493 Make --listen-address higher priority than --except-interface
494 in all circumstances. Thanks to Thomas Hood for the bugreport.
496 Provide independent control over which interfaces get TFTP
497 service. If enable-tftp is given a list of interfaces, then TFTP
498 is provided on those. Without the list, the previous behaviour
499 (provide TFTP to the same interfaces we provide DHCP to)
500 is retained. Thanks to Lonnie Abelbeck for the suggestion.
502 Add --dhcp-relay config option. Many thanks to vtsl.net
503 for sponsoring this development.
505 Fix crash with empty tag: in --dhcp-range. Thanks to
506 Kaspar Schleiser for the bug report.
508 Add "baseline" and "bloatcheck" makefile targets, for
509 revealing size changes during development. Thanks to
510 Vladislav Grishenko for the patch.
512 Cope with DHCPv6 clients which send REQUESTs without
513 address options - treat them as SOLICIT with rapid commit.
515 Support identification of clients by MAC address in
516 DHCPv6. When using a relay, the relay must support RFC
517 6939 for this to work. It always works for directly
518 connected clients. Thanks to Vladislav Grishenko
519 for prompting this feature.
521 Remove the rule for constructed DHCP ranges that the local
522 address must be either the first or last address in the
523 range. This was originally to avoid SLAAC addresses, but
524 we now explicitly autoconfig and privacy addresses instead.
526 Update Polish translation. Thanks to Jan Psota.
528 Fix problem in DHCPv6 vendorclass/userclass matching
529 code. Thanks to Tanguy Bouzeloc for the patch.
531 Update Spanish transalation. Thanks to Vicente Soriano.
533 Add --ra-param option. Thanks to Vladislav Grishenko for
536 Add --add-subnet configuration, to tell upstream DNS
537 servers where the original client is. Thanks to DNSthingy
538 for sponsoring this feature.
540 Add --quiet-dhcp, --quiet-dhcp6 and --quiet-ra. Thanks to
541 Kevin Darbyshire-Bryant for the initial patch.
543 Allow A/AAAA records created by --interface-name to be the
544 target of --cname. Thanks to Hadmut Danisch for the
547 Avoid treating a --dhcp-host which has an IPv6 address
548 as eligable for use with DHCPv4 on the grounds that it has
549 no address, and vice-versa. Thanks to Yury Konovalov for
550 spotting the problem.
552 Do a better job caching dangling CNAMEs. Thanks to Yves
553 Dorfsman for spotting the problem.
557 Add the ability to act as an authoritative DNS
558 server. Dnsmasq can now answer queries from the wider 'net
559 with local data, as long as the correct NS records are set
560 up. Only local data is provided, to avoid creating an open
561 DNS relay. Zone transfer is supported, to allow secondary
562 servers to be configured.
564 Add "constructed DHCP ranges" for DHCPv6. This is intended
565 for IPv6 routers which get prefixes dynamically via prefix
566 delegation. With suitable configuration, stateful DHCPv6
567 and RA can happen automatically as prefixes are delegated
568 and then deprecated, without having to re-write the
569 dnsmasq configuration file or restart the daemon. Thanks to
570 Steven Barth for extensive testing and development work on
573 Fix crash on startup on Solaris 11. Regression probably
574 introduced in 2.61. Thanks to Geoff Johnstone for the
577 Add code to make behaviour for TCP DNS requests that same
578 as for UDP requests, when a request arrives for an allowed
579 address, but via a banned interface. This change is only
580 active on Linux, since the relevant API is missing (AFAIK)
581 on other platforms. Many thanks to Tomas Hozza for
582 spotting the problem, and doing invaluable discovery of
583 the obscure and undocumented API required for the solution.
585 Don't send the default DHCP option advertising dnsmasq as
586 the local DNS server if dnsmasq is configured to not act
587 as DNS server, or it's configured to a non-standard port.
589 Add DNSMASQ_CIRCUIT_ID, DNSMASQ_SUBCRIBER_ID,
590 DNSMASQ_REMOTE_ID variables to the environment of the
591 lease-change script (and the corresponding Lua). These hold
592 information inserted into the DHCP request by a DHCP relay
593 agent. Thanks to Lakefield Communications for providing a
594 bounty for this addition.
596 Fixed crash, introduced in 2.64, whilst handling DHCPv6
597 information-requests with some common configurations.
598 Thanks to Robert M. Albrecht for the bug report and
601 Add --ipset option. Thanks to Jason A. Donenfeld for the
604 Don't erroneously reject some option names in --dhcp-match
605 options. Thanks to Benedikt Hochstrasser for the bug report.
607 Allow a trailing '*' wildcard in all interface-name
608 configurations. Thanks to Christian Parpart for the patch.
610 Handle the situation where libc headers define
611 SO_REUSEPORT, but the kernel in use doesn't, to cope with
612 the introduction of this option to Linux. Thanks to Rich
613 Felker for the bug report.
615 Update Polish translation. Thanks to Jan Psota.
617 Fix crash if the configured DHCP lease limit is
618 reached. Regression occurred in 2.61. Thanks to Tsachi for
621 Update the French translation. Thanks to Gildas le Nadan.
625 Fix regression which broke forwarding of queries sent via
626 TCP which are not for A and AAAA and which were directed to
627 non-default servers. Thanks to Niax for the bug report.
629 Fix failure to build with DHCP support excluded. Thanks to
630 Gustavo Zacarias for the patch.
632 Fix nasty regression in 2.64 which completely broke cacheing.
636 Handle DHCP FQDN options with all flag bits zero and
637 --dhcp-client-update set. Thanks to Bernd Krumbroeck for
638 spotting the problem.
640 Finesse the check for /etc/hosts names which conflict with
641 DHCP names. Previously a name/address pair in /etc/hosts
642 which didn't match the name/address of a DHCP lease would
643 generate a warning. Now that only happesn if there is not
644 also a match. This allows multiple addresses for a name in
645 /etc/hosts with one of them assigned via DHCP.
647 Fix broken vendor-option processing for BOOTP. Thanks to
648 Hans-Joachim Baader for the bug report.
650 Don't report spurious netlink errors, regression in
651 2.63. Thanks to Vladislav Grishenko for the patch.
653 Flag DHCP or DHCPv6 in starup logging. Thanks to
654 Vladislav Grishenko for the patch.
656 Add SetServersEx method in DBus interface. Thanks to Dan
657 Williams for the patch.
659 Add SetDomainServers method in DBus interface. Thanks to
660 Roy Marples for the patch.
662 Fix build with later Lua libraries. Thansk to Cristian
663 Rodriguez for the patch.
665 Add --max-cache-ttl option. Thanks to Dennis Kaarsemaker
668 Fix breakage of --host-record parsing, resulting in
669 infinte loop at startup. Regression in 2.63. Thanks to
670 Haim Gelfenbeyn for spotting this.
672 Set SO_REUSEADDRESS and SO_V6ONLY options on the DHCPv6
673 socket, this allows multiple instances of dnsmasq on a
674 single machine, in the same way as for DHCPv4. Thanks to
675 Gene Czarcinski and Vladislav Grishenko for work on this.
677 Fix DHCPv6 to do access control correctly when it's
678 configured with --listen-address. Thanks to
679 Gene Czarcinski for sorting this out.
681 Add a "wildcard" dhcp-range which works for any IPv6
682 subnet, --dhcp-range=::,static Useful for Stateless
683 DHCPv6. Thanks to Vladislav Grishenko for the patch.
685 Don't include lease-time in DHCPACK replies to DHCPINFORM
686 queries, since RFC-2131 says we shouldn't. Thanks to
687 Wouter Ibens for pointing this out.
689 Makefile tweak to do dependency checking on header files.
690 Thanks to Johan Peeters for the patch.
692 Check interface for outgoing unsolicited router
693 advertisements, rather than relying on interface address
694 configuration. Thanks to Gene Czarinski for the patch.
696 Handle better attempts to transmit on interfaces which are
697 still doing DAD, and specifically do not just transmit
698 without setting source address and interface, since this
699 can cause very puzzling effects when a router
700 advertisement goes astray. Thanks again to Gene Czarinski.
702 Get RA timers right when there is more than one
703 dhcp-range on a subnet.
707 Do duplicate dhcp-host address check in --test mode.
709 Check that tftp-root directories are accessible before
710 start-up. Thanks to Daniel Veillard for the initial patch.
712 Allow more than one --tfp-root flag. The per-interface
713 stuff is pointless without that.
715 Add --bind-dynamic. A hybrid mode between the default and
716 --bind-interfaces which copes with dynamically created
719 A couple of fixes to the build system for Android. Thanks
720 to Metin Kaya for the patches.
722 Remove the interface:<interface> argument in --dhcp-range, and
723 the interface argument to --enable-tftp. These were a
724 still-born attempt to allow automatic isolated
725 configuration by libvirt, but have never (to my knowledge)
726 been used, had very strange semantics, and have been
727 superceded by other mechanisms.
729 Fixed bug logging filenames when duplicate dhcp-host
730 addresses are found. Thanks to John Hanks for the patch.
732 Fix regression in 2.61 which broke caching of CNAME
733 chains. Thanks to Atul Gupta for the bug report.
735 Allow the target of a --cname flag to be another --cname.
737 Teach DHCPv6 about the RFC 4242 information-refresh-time
738 option, and add parsing if the minutes, hours and days
739 format for options. Thanks to Francois-Xavier Le Bail for
742 Allow "w" (for week) as multiplier in lease times, as well
743 as seconds, minutes, hours and days. Álvaro Gámez Machado
744 spotted the ommission.
746 Update French translation. Thanks to Gildas Le Nadan.
748 Allow a DBus service name to be given with --enable-dbus
749 which overrides the default,
750 uk.org.thekelleys.dnsmasq. Thanks to Mathieu
751 Trudel-Lapierre for the patch.
753 Set the "prefix on-link" bit in Router
754 Advertisements. Thanks to Gui Iribarren for the patch.
758 Update German translation. Thanks to Conrad Kostecki.
760 Cope with router-solict packets wich don't have a valid
761 source address. Thanks to Vladislav Grishenko for the patch.
763 Fixed bug which caused missing periodic router
764 advertisements with some configurations. Thanks to
765 Vladislav Grishenko for the patch.
767 Fixed bug which broke DHCPv6/RA with prefix lengths
768 which are not divisible by 8. Thanks to Andre Coetzee
771 Fix non-response to router-solicitations when
772 router-advertisement configured, but DHCPv6 not
773 configured. Thanks to Marien Zwart for the patch.
775 Add --dns-rr, to allow arbitrary DNS resource records.
777 Fixed bug which broke RA scheduling when an interface had
778 two addresses in the same network. Thanks to Jim Bos for
779 his help nailing this.
782 Re-write interface discovery code on *BSD to use
783 getifaddrs. This is more portable, more straightforward,
784 and allows us to find the prefix length for IPv6
787 Add ra-names, ra-stateless and slaac keywords for DHCPv6.
788 Dnsmasq can now synthesise AAAA records for dual-stack
789 hosts which get IPv6 addresses via SLAAC. It is also now
790 possible to use SLAAC and stateless DHCPv6, and to
791 tell clients to use SLAAC addresses as well as DHCP ones.
792 Thanks to Dave Taht for help with this.
794 Add --dhcp-duid to allow DUID-EN uids to be used.
796 Explicity send DHCPv6 replies to the correct port, instead
797 of relying on clients to send requests with the correct
798 source address, since at least one client in the wild gets
799 this wrong. Thanks to Conrad Kostecki for help tracking
802 Send a preference value of 255 in DHCPv6 replies when
803 --dhcp-authoritative is in effect. This tells clients not
804 to wait around for other DHCP servers.
806 Better logging of DHCPv6 options.
808 Add --host-record. Thanks to Rob Zwissler for the
811 Invoke the DHCP script with action "tftp" when a TFTP file
812 transfer completes. The size of the file, address to which
813 it was sent and complete pathname are supplied. Note that
814 version 2.60 introduced some script incompatibilties
815 associated with DHCPv6, and this is a further change. To
816 be safe, scripts should ignore unknown actions, and if
817 not IPv6-aware, should exit if the environment
818 variable DNSMASQ_IAID is set. The use-case for this is
819 to track netboot/install. Suggestion from Shantanu
822 Update contrib/port-forward/dnsmasq-portforward to reflect
825 Set the environment variable DNSMASQ_LOG_DHCP when running
826 the script id --log-dhcp is in effect, so that script can
827 taylor their logging verbosity. Suggestion from Malte
830 Arrange that addresses specified with --listen-address
831 work even if there is no interface carrying the
832 address. This is chiefly useful for IPv4 loopback
833 addresses, where any address in 127.0.0.0/8 is a valid
834 loopback address, but normally only 127.0.0.1 appears on
835 the lo interface. Thanks to Mathieu Trudel-Lapierre for
836 the idea and initial patch.
838 Fix crash, introduced in 2.60, when a DHCPINFORM is
839 received from a network which has no valid dhcp-range.
840 Thanks to Stephane Glondu for the bug report.
842 Add a new DHCP lease time keyword, "deprecated" for
843 --dhcp-range. This is only valid for IPv6, and sets the
844 preffered lease time for both DHCP and RA to zero. The
845 effect is that clients can continue to use the address
846 for existing connections, but new connections will use
847 other addresses, if they exist. This makes hitless
848 renumbering at least possible.
850 Fix bug in address6_available() which caused DHCPv6 lease
851 aquisition to fail if more than one dhcp-range in use.
853 Provide RDNSS and DNSSL data in router advertisements,
854 using the settings provided for DHCP options
855 option6:domain-search and option6:dns-server.
857 Tweak logo/favicon.ico to add some transparency. Thanks to
858 SamLT for work on this.
860 Don't cache data from non-recursive nameservers, since it
861 may erroneously look like a valid CNAME to a non-exitant
862 name. Thanks to Ben Winslow for finding this.
864 Call SO_BINDTODEVICE on the DHCP socket(s) when doing DHCP
865 on exactly one interface and --bind-interfaces is set. This
866 makes the OpenStack use-case of one dnsmasq per virtual
867 interface work. This is only available on Linux; it's not
868 supported on other platforms. Thanks to Vishvananda Ishaya
869 and the OpenStack team for the suggestion.
871 Updated French translation. Thanks to Gildas Le Nadan.
873 Give correct from-cache answers to explict CNAME queries.
874 Thanks to Rob Zwissler for spotting this.
876 Add --tftp-lowercase option. Thanks to Oliver Rath for the
879 Ensure that the DBus DhcpLeaseUpdated events are generated
880 when a lease goes through INIT_REBOOT state, even if the
881 dhcp-script is not in use. Thanks to Antoaneta-Ecaterina
884 Fix failure of TFTP over IPv4 on OpenBSD platform. Thanks
885 to Brad Smith for spotting this.
889 Fix compilation problem in Mac OS X Lion. Thanks to Olaf
890 Flebbe for the patch.
892 Fix DHCP when using --listen-address with an IP address
893 which is not the primary address of an interface.
895 Add --dhcp-client-update option.
897 Add Lua integration. Dnsmasq can now execute a DHCP
898 lease-change script written in Lua. This needs to be
899 enabled at compile time by setting HAVE_LUASCRIPT in
900 src/config.h or running "make COPTS=-DHAVE_LUASCRIPT"
901 Thanks to Jan-Piet Mens for the idea and proof-of-concept
904 Tidied src/config.h to distinguish between
905 platform-dependent compile-time options which are selected
906 automatically, and builder-selectable compile time
907 options. Document the latter better, and describe how to
908 set them from the make command line.
910 Tidied up IPPROTO_IP/SOL_IP (and IPv6 equivalent)
911 confusion. IPPROTO_IP works everywhere now.
913 Set TOS on DHCP sockets, this improves things on busy
914 wireless networks. Thanks to Dave Taht for the patch.
916 Determine VERSION automatically based on git magic:
917 release tags or hash values.
919 Improve start-up speed when reading large hosts files
920 containing many distinct addresses.
922 Fix problem if dnsmasq is started without the stdin,
923 stdout and stderr file descriptors open. This can manifest
924 itself as 100% CPU use. Thanks to Chris Moore for finding
927 Fix shell-scripting bug in bld/pkg-wrapper. Thanks to
928 Mark Mitchell for the patch.
930 Allow the TFP server or boot server in --pxe-service, to
931 be a domain name instead of an IP address. This allows for
932 round-robin to multiple servers, in the same way as
933 --dhcp-boot. A good suggestion from Cristiano Cumer.
935 Support BUILDDIR variable in the Makefile. Allows builds
936 for multiple archs from the same source tree with eg.
937 make BUILDDIR=linux (relative to dnsmasq tree)
938 make BUILDDIR=/tmp/openbsd (absolute path)
939 If BUILDDIR is not set, compilation happens in the src
940 directory, as before. Suggestion from Mark Mitchell.
942 Support DHCPv6. Support is there for the sort of things
943 the existing v4 server does, including tags, options,
944 static addresses and relay support. Missing is prefix
945 delegation, which is probably not required in the dnsmasq
946 niche, and an easy way to accept prefix delegations from
947 an upstream DHCPv6 server, which is. Future plans include
948 support for DHCPv6 router option and MAC address option
949 (to make selecting clients by MAC address work like IPv4).
950 These will be added as the standards mature.
951 This code has been tested, but this is the first release,
952 so don't bet the farm on it just yet. Many thanks to all
953 testers who have got it this far.
955 Support IPv6 router advertisements. This is a
956 simple-minded implementation, aimed at providing the
957 vestigial RA needed to go alongside IPv6. Is picks up
958 configuration from the DHCPv6 conf, and should just need
959 enabling with --enable-ra.
961 Fix long-standing wrinkle with --localise-queries that
962 could result in wrong answers when DNS packets arrive
963 via an interface other than the expected one. Thanks to
964 Lorenzo Milesi and John Hanks for spotting this one.
966 Update French translation. Thanks to Gildas Le Nadan.
968 Update Polish translation. Thanks to Jan Psota.
972 Fix regression in 2.58 which caused failure to start up
973 with some combinations of dnsmasq config and IPv6 kernel
974 network config. Thanks to Brielle Bruns for the bug
977 Improve dnsmasq's behaviour when network interfaces are
978 still doing duplicate address detection (DAD). Previously,
979 dnsmasq would wait up to 20 seconds at start-up for the
980 DAD state to terminate. This is broken for bridge
981 interfaces on recent Linux kernels, which don't start DAD
982 until the bridge comes up, and so can take arbitrary
983 time. The new behaviour lets dnsmasq poll for an arbitrary
984 time whilst providing service on other interfaces. Thanks
985 to Stephen Hemminger for pointing out the problem.
989 Provide a definition of the SA_SIZE macro where it's
990 missing. Fixes build failure on openBSD.
992 Don't include a zero terminator at the end of messages
993 sent to /dev/log when /dev/log is a datagram socket.
994 Thanks to Didier Rabound for spotting the problem.
996 Add --dhcp-sequential-ip flag, to force allocation of IP
997 addresses in ascending order. Note that the default
998 pseudo-random mode is in general better but some
999 server-deployment applications need this.
1001 Fix problem where a server-id of 0.0.0.0 is sent to a
1002 client when a dhcp-relay is in use if a client renews a
1003 lease after dnsmasq restart and before any clients on the
1004 subnet get a new lease. Thanks to Mike Ruiz for assistance
1005 in chasing this one down.
1007 Don't return NXDOMAIN to an AAAA query if we have CNAME
1008 which points to an A record only: NODATA is the correct
1009 reply in this case. Thanks to Tom Fernandes for spotting
1012 Relax the need to supply a netmask in --dhcp-range for
1013 networks which use a DHCP relay. Whilst this is still
1014 desireable, in the absence of a netmask dnsmasq will use
1015 a default based on the class (A, B, or C) of the address.
1016 This should at least remove a cause of mysterious failure
1017 for people using RFC1918 addresses and relays.
1019 Add support for Linux conntrack connection marking. If
1020 enabled with --conntrack, the connection mark for incoming
1021 DNS queries will be copied to the outgoing connections
1022 used to answer those queries. This allows clever firewall
1023 and accounting stuff. Only available if dnsmasq is
1024 compiled with HAVE_CONNTRACK and adds a dependency on
1025 libnetfilter-conntrack. Thanks to Ed Wildgoose for the
1026 initial idea, testing and sponsorship of this function.
1028 Provide a sane error message when someone attempts to
1029 match a tag in --dhcp-host.
1031 Tweak the behaviour of --domain-needed, to avoid problems
1032 with recursive nameservers downstream of dnsmasq. The new
1033 behaviour only stops A and AAAA queries, and returns
1034 NODATA rather than NXDOMAIN replies.
1036 Efficiency fix for very large DHCP configurations, thanks
1037 to James Gartrell and Mike Ruiz for help with this.
1039 Allow the TFTP-server address in --dhcp-boot to be a
1040 domain-name which is looked up in /etc/hosts. This can
1041 give multiple IP addresses which are used round-robin,
1042 thus doing TFTP server load-balancing. Thanks to Sushil
1043 Agrawal for the patch.
1045 When two tagged dhcp-options for a particular option
1046 number are both valid, use the one which is valid without
1047 a tag from the dhcp-range. Allows overriding of the value
1048 of a DHCP option for a particular host as well as
1049 per-network values. So
1050 --dhcp-range=set:interface1,......
1051 --dhcp-host=set:myhost,.....
1052 --dhcp-option=tag:interface1,option:nis-domain,"domain1"
1053 --dhcp-option=tag:myhost,option:nis-domain,"domain2"
1054 will set the NIS-domain to domain1 for hosts in the range, but
1055 override that to domain2 for a particular host.
1057 Fix bug which resulted in truncated files and timeouts for
1058 some TFTP transfers. The bug only occurs with netascii
1059 transfers and needs an unfortunate relationship between
1060 file size, blocksize and the number of newlines in the
1061 last block before it manifests itself. Many thanks to
1062 Alkis Georgopoulos for spotting the problem and providing
1063 a comprehensive test-case.
1065 Fix regression in TFTP server on *BSD platforms introduced
1066 in version 2.56, due to confusion with sockaddr
1067 length. Many thanks to Loic Pefferkorn for finding this.
1069 Support scope-ids in IPv6 addresses of nameservers from
1070 /etc/resolv.conf and in --server options. Eg
1071 nameserver fe80::202:a412:4512:7bbf%eth0 or
1072 server=fe80::202:a412:4512:7bbf%eth0. Thanks to
1073 Michael Stapelberg for the suggestion.
1075 Update Polish translation, thanks to Jan Psota.
1077 Update French translation. Thanks to Gildas Le Nadan.
1081 Add patches to allow build under Android.
1083 Provide our own header for the DNS protocol, rather than
1084 relying on arpa/nameser.h. This has proved more or less
1085 defective over the years and the final straw is that it's
1086 effectively empty on Android.
1088 Fix regression in 2.56 which caused hex constants in
1089 configuration to be rejected if they contain the '*'
1092 Correct wrong casts of arguments to ctype.h functions,
1093 isdigit(), isxdigit() etc. Thanks to Matthias Andree for
1096 Allow build with IDN support independently from i18n.
1097 IDN support continues to be included automatically
1098 when i18n is included.
1099 'make COPTS=-DHAVE_IDN' is the magic incantation.
1101 Modify check on extraneous command line junk (added in
1102 2.56) so that it doesn't complain about extra _empty_
1103 arguments. Otherwise this breaks libvirt.
1107 Add a patch to allow dnsmasq to get interface names right in a
1108 Solaris zone. Thanks to Dj Padzensky for this.
1110 Improve data-type parsing heuristics so that
1111 --dhcp-option=option:domain-search,.
1112 treats the value as a string and not an IP address.
1113 Thanks to Clemens Fischer for spotting that.
1115 Add IPv6 support to the TFTP server. Many thanks to Jan
1116 'RedBully' Seiffert for the patches.
1118 Log DNS queries at level LOG_INFO, rather then
1119 LOG_DEBUG. This makes things consistent with DHCP
1120 logging. Thanks to Adam Pribyl for spotting the problem.
1122 Ensure that dnsmasq terminates cleanly when using
1123 --syslog-async even if it cannot make a connection to the
1126 Add --add-mac option. This is to support currently
1127 experimental DNS filtering facilities. Thanks to Benjamin
1128 Petrin for the orignal patch.
1130 Fix bug which meant that tags were ignored in dhcp-range
1131 configuration specifying PXE-proxy service. Thanks to
1132 Cristiano Cumer for spotting this.
1134 Raise an error if there is extra junk, not part of an
1135 option, on the command line.
1137 Flag a couple of log messages in cache.c as coming from
1138 the DHCP subsystem. Thanks to Olaf Westrik for the patch.
1140 Omit timestamps from logs when a) logging to stderr and
1141 b) --keep-in-forground is set. The logging facility on the
1142 other end of stderr can be assumned to supply them. Thanks
1143 to John Hallam for the patch.
1145 Don't complain about strings longer than 255 characters in
1146 --txt-record, just split the long strings into 255
1147 character chunks instead.
1149 Fix crash on double-free. This bug can only happen when
1150 dhcp-script is in use and then only in rare circumstances
1151 triggered by high DHCP transaction rate and a slow
1152 script. Thanks to Ferenc Wagner for finding the problem.
1154 Only log that a file has been sent by TFTP after the
1155 transfer has completed succesfully.
1157 A good suggestion from Ferenc Wagner: extend
1158 the --domain option to allow this sort of thing:
1159 --domain=thekelleys.org.uk,192.168.0.0/24,local
1160 which automatically creates
1161 --local=/thekelleys.org.uk/
1162 --local=/0.168.192.in-addr.arpa/
1164 Tighten up syntax checking of hex contants in the config
1165 file. Thanks to Fred Damen for spotting this.
1167 Add dnsmasq logo/icon, contributed by Justin Swift. Many
1170 Never cache DNS replies which have the 'cd' bit set, or
1171 which result from queries forwarded with the 'cd' bit
1172 set. The 'cd' bit instructs a DNSSEC validating server
1173 upstream to ignore signature failures and return replies
1174 anyway. Without this change it's possible to pollute the
1175 dnsmasq cache with bad data by making a query with the
1176 'cd' bit set and subsequent queries would return this data
1177 without its being marked as suspect. Thanks to Anders
1178 Kaseorg for pointing out this problem.
1180 Add --proxy-dnssec flag, for compliance with RFC
1181 4035. Dnsmasq will now clear the 'ad' bit in answers returned
1182 from upstream validating nameservers unless this option is
1185 Allow a filename of "-" for --conf-file to read
1186 stdin. Suggestion from Timothy Redaelli.
1188 Rotate the order of SRV records in replies, to provide
1189 round-robin load balancing when all the priorities are
1190 equal. Thanks to Peter McKinney for the suggestion.
1193 contrib/MacOSX-launchd/uk.org.thekelleys.dnsmasq.plist
1194 so that it doesn't log all queries to a file by
1195 default. Thanks again to Peter McKinney.
1197 By default, setting an IPv4 address for a domain but not
1198 an IPv6 address causes dnsmasq to return
1199 an NODATA reply for IPv6 (or vice-versa). So
1200 --address=/google.com/1.2.3.4 stops IPv6 queries for
1201 *google.com from being forwarded. Make it possible to
1202 override this behaviour by defining the sematics if the
1203 same domain appears in both --server and --address.
1204 In that case, the --address has priority for the address
1205 family in which is appears, but the --server has priority
1206 of the address family which doesn't appear in --adddress
1208 --address=/google.com/1.2.3.4
1209 --server=/google.com/#
1210 will return 1.2.3.4 for IPv4 queries for *.google.com but
1211 forward IPv6 queries to the normal upstream nameserver.
1212 Similarly when setting an IPv6 address
1213 only this will allow forwarding of IPv4 queries. Thanks to
1214 William for pointing out the need for this.
1216 Allow more than one --dhcp-optsfile and --dhcp-hostsfile
1217 and make them understand directories as arguments in the
1218 same way as --addn-hosts. Suggestion from John Hanks.
1220 Ignore rebinding requests for leases we don't know
1221 about. Rebind is broadcast, so we might get to overhear a
1222 request meant for another DHCP server. NAKing this is
1223 wrong. Thanks to Brad D'Hondt for assistance with this.
1225 Fix cosmetic bug which produced strange output when
1226 dumping cache statistics with some configurations. Thanks
1227 to Fedor Kozhevnikov for spotting this.
1231 Fix crash when /etc/ethers is in use. Thanks to
1232 Gianluigi Tiesi for finding this.
1234 Fix crash in netlink_multicast(). Thanks to Arno Wald for
1237 Allow the empty domain "." in dhcp domain-search (119)
1242 There is no version 2.54 to avoid confusion with 2.53,
1243 which incorrectly identifies itself as 2.54.
1247 Fix failure to compile on Debian/kFreeBSD. Thanks to
1248 Axel Beckert and Petr Salinger.
1250 Fix code to avoid scary strict-aliasing warnings
1251 generated by gcc 4.4.
1253 Added FAQ entry warning about DHCP failures with Vista
1254 when firewalls block 255.255.255.255.
1256 Fixed bug which caused bad things to happen if a
1257 resolv.conf file which exists is subsequently removed.
1258 Thanks to Nikolai Saoukh for the patch.
1260 Rationalised the DHCP tag system. Every configuration item
1261 which can set a tag does so by adding "set:<tag>" and
1262 every configuration item which is conditional on a tag is
1263 made so by "tag:<tag>". The NOT operator changes to '!',
1264 which is a bit more intuitive too. Dhcp-host directives
1265 can set more than one tag now. The old '#' NOT,
1266 "net:" prefix and no-prefixes are still honoured, so
1267 no existing config file needs to be changed, but
1268 the documentation and new-style config files should be
1269 much less confusing.
1271 Added --tag-if to allow boolean operations on tags.
1272 This allows complicated logic to be clearer and more
1273 general. A great suggestion from Richard Voigt.
1275 Add broadcast/unicast information to DHCP logging.
1277 Allow --dhcp-broadcast to be unconditional.
1279 Fixed incorrect behaviour with NOT <tag> conditionals in
1280 dhcp-options. Thanks to Max Turkewitz for assistance
1283 If we send vendor-class encapsulated options based on the
1284 vendor-class supplied by the client, and no explicit
1285 vendor-class option is given, echo back the vendor-class
1288 Fix bug which stopped dnsmasq from matching both a
1289 circuitid and a remoteid. Thanks to Ignacio Bravo for
1292 Add --dhcp-proxy, which makes it possible to configure
1293 dnsmasq to use a DHCP relay agent as a full proxy, with
1294 all DHCP messages passing through the proxy. This is
1295 useful if the relay adds extra information to the packets
1296 it forwards, but cannot be configured with the RFC 5107
1297 server-override option.
1299 Added interface:<iface name> part to dhcp-range. The
1300 semantics of this are very odd at first sight, but it
1301 allows a single line of the form
1302 dhcp-range=interface:virt0,192.168.0.4,192.168.0.200
1303 to be added to dnsmasq configuration which then supplies
1304 DHCP and DNS services to that interface, without affecting
1305 what services are supplied to other interfaces and
1306 irrespective of the existance or lack of
1307 interface=<interface>
1308 lines elsewhere in the dnsmasq configuration. The idea is
1309 that such a line can be added automatically by libvirt
1310 or equivalent systems, without disturbing any manual
1313 Similarly to the above, allow --enable-tftp=<interface>
1315 Allow a TFTP root to be set separately for requests via
1316 different interfaces, --tftp-root=<path>,<interface>
1318 Correctly handle and log clashes between CNAMES and
1319 DNS names being given to DHCP leases. This fixes a bug
1320 which caused nonsense IP addresses to be logged. Thanks to
1321 Sergei Zhirikov for finding and analysing the problem.
1323 Tweak flush_log so as to avoid leaving the log
1324 file in non-blocking mode. O_NONBLOCK is a property of the
1325 file, not the process/descriptor.
1327 Fix contrib/Solaris10/create_package
1328 (/usr/man -> /usr/share/man) Thanks to Vita Batrla.
1330 Fix a problem where, if a client got a lease, then went
1331 to another subnet and got another lease, then moved back,
1332 it couldn't resume the old lease, but would instead get
1333 a new address. Thanks to Leonardo Rodrigues for spotting
1334 this and testing the fix.
1336 Fix weird bug which sometimes omitted certain characters
1337 from the start of quoted strings in dhcp-options. Thanks
1338 to Dayton Turner for spotting the problem.
1340 Add facility to redirect some domains to the standard
1341 upstream servers: this allows something like
1342 --server=/google.com/1.2.3.4 --server=/www.google.com/#
1343 which will send queries for *.google.com to 1.2.3.4,
1344 except *www.google.com which will be forwarded as usual.
1345 Thanks to AJ Weber for prompting this addition.
1347 Improve the hash-algorithm used to generate IP addresses
1348 from MAC addresses during initial DHCP address
1349 allocation. This improves performance when large numbers
1350 of hosts with similar MAC addresses all try and get an IP
1351 address at the same time. Thanks to Paul Smith for his
1354 Tweak DHCP code so that --bridge-interface can be used to
1355 select which IP alias of an interface should be used for
1356 DHCP purposes on Linux. If eth0 has an alias eth0:dhcp
1357 then adding --bridge-interface=eth0:dhcp,eth0 will use
1358 the address of eth0:dhcp to determine the correct subnet
1359 for DHCP address allocation. Thanks to Pawel Golaszewski
1360 for prompting this and Eric Cooper for further testing.
1362 Add --dhcp-generate-names. Suggestion by Ferenc Wagner.
1364 Tweak DNS server selection algorithm when there is more
1365 than one server available for a domain, eg.
1366 --server=/mydomain/1.1.1.1
1367 --server=/mydomain/2.2.2.2
1368 Thanks to Alberto Cuesta-Canada for spotting a weakness
1371 Add --max-ttl. Thanks to Fredrik Ringertz for the patch.
1373 Allow --log-facility=- to force all logging to
1374 stderr. Suggestion from Clemens Fischer.
1376 Fix regression which caused configuration like
1377 --address=/.domain.com/1.2.3.4 to be rejected. The dot to the
1378 left of the domain has been implied and not required for a
1379 long time, but it should be accepted for backward
1380 compatibility. Thanks to Andrew Burcin for spotting this.
1382 Add --rebind-domain-ok and --rebind-localhost-ok.
1383 Suggestion from Clemens Fischer.
1385 Log replies to queries of type TXT, when --log-queries
1388 Fix compiler warnings when compiled with -DNO_DHCP. Thanks
1389 to Shantanu Gadgil for the patch.
1391 Updated French translation. Thanks to Gildas Le Nadan.
1393 Updated Polish translation. Thanks to Jan Psota.
1395 Updated German translation. Thanks to Matthias Andree.
1397 Added contrib/static-arp, thanks to Darren Hoo.
1399 Fix corruption of the domain when a name from /etc/hosts
1400 overrides one supplied by a DHCP client. Thanks to Fedor
1401 Kozhevnikov for spotting the problem.
1403 Updated Spanish translation. Thanks to Chris Chatham.
1407 Work around a Linux kernel bug which insists that the
1408 length of the option passed to setsockopt must be at least
1409 sizeof(int) bytes, even if we're calling SO_BINDTODEVICE
1410 and the device name is "lo". Note that this is fixed
1411 in kernel 2.6.31, but the workaround is harmless and
1412 allows earlier kernels to be used. Also fix dnsmasq
1413 bug which reported the wrong address when this failed.
1414 Thanks to Fedor for finding this.
1416 The API for IPv6 PKTINFO changed around Linux kernel
1417 2.6.14. Workaround the case where dnsmasq is compiled
1418 against newer headers, but then run on an old kernel:
1419 necessary for some *WRT distros.
1421 Re-read the set of network interfaces when re-loading
1422 /etc/resolv.conf if --bind-interfaces is not set. This
1423 handles the case that loopback interfaces do not exist
1424 when dnsmasq is first started.
1426 Tweak the PXE code to support port 4011. This should
1427 reduce broadcasts and make things more reliable when other
1428 servers are around. It also improves inter-operability
1429 with certain clients.
1431 Make a pxe-service configuration with no filename or boot
1432 service type legal: this does a local boot. eg.
1433 pxe-service=x86PC, "Local boot"
1435 Be more conservative in detecting "A for A"
1436 queries. Dnsmasq checks if the name in a type=A query looks
1437 like a dotted-quad IP address and answers the query itself
1438 if so, rather than forwarding it. Previously dnsmasq
1439 relied in the library function inet_addr() to convert
1440 addresses, and that will accept some things which are
1441 confusing in this context, like 1.2.3 or even just
1442 1234. Now we only do A for A processing for four decimal
1443 numbers delimited by dots.
1445 A couple of tweaks to fix compilation on Solaris. Thanks
1446 to Joel Macklow for help with this.
1448 Another Solaris compilation tweak, needed for Solaris
1449 2009.06. Thanks to Lee Essen for that.
1451 Added extract packaging stuff from Lee Essen to
1454 Increased the default limit on number of leases to 1000
1455 (from 150). This is mainly a defence against DoS attacks,
1456 and for the average "one for two class C networks"
1457 installation, IP address exhaustion does that just as
1458 well. Making the limit greater than the number of IP
1459 addresses available in such an installation removes a
1460 surprise which otherwise can catch people out.
1462 Removed extraneous trailing space in the value of the
1463 DNSMASQ_TIME_REMAINING DNSMASQ_LEASE_LENGTH and
1464 DNSMASQ_LEASE_EXPIRES environment variables. Thanks to
1465 Gildas Le Nadan for spotting this.
1467 Provide the network-id tags for a DHCP transaction to
1468 the lease-change script in the environment variable
1469 DNSMASQ_TAGS. A good suggestion from Gildas Le Nadan.
1471 Add support for RFC3925 "Vendor-Identifying Vendor
1472 Options". The syntax looks like this:
1473 --dhcp-option=vi-encap:<enterprise number>, .........
1475 Add support to --dhcp-match to allow matching against
1476 RFC3925 "Vendor-Identifying Vendor Classes". The syntax
1478 --dhcp-match=tag,vi-encap<enterprise number>, <value>
1480 Add some application specific code to assist in
1481 implementing the Broadband forum TR069 CPE-WAN
1482 specification. The details are in contrib/CPE-WAN/README
1484 Increase the default DNS packet size limit to 4096, as
1485 recommended by RFC5625 section 4.4.3. This can be
1486 reconfigured using --edns-packet-max if needed. Thanks to
1487 Francis Dupont for pointing this out.
1489 Rewrite query-ids even for TSIG signed packets, since
1490 this is allowed by RFC5625 section 4.5.
1492 Use getopt_long by default on OS X. It has been supported
1493 since version 10.3.0. Thanks to Arek Dreyer for spotting
1496 Added up-to-date startup configuration for MacOSX/launchd
1497 in contrib/MacOSX-launchd. Thanks to Arek Dreyer for
1500 Fix link error when including Dbus but excluding DHCP.
1501 Thanks to Oschtan for the bug report.
1503 Updated French translation. Thanks to Gildas Le Nadan.
1505 Updated Polish translation. Thanks to Jan Psota.
1507 Updated Spanish translation. Thanks to Chris Chatham.
1509 Fixed confusion about domains, when looking up DHCP hosts
1510 in /etc/hosts. This could cause spurious "Ignoring
1511 domain..." messages. Thanks to Fedor Kozhevnikov for
1512 finding and analysing the problem.
1516 Add support for internationalised DNS. Non-ASCII characters
1517 in domain names found in /etc/hosts, /etc/ethers and
1518 /etc/dnsmasq.conf will be correctly handled by translation to
1519 punycode, as specified in RFC3490. This function is only
1520 available if dnsmasq is compiled with internationalisation
1521 support, and adds a dependency on GNU libidn. Without i18n
1522 support, dnsmasq continues to be compilable with just
1523 standard tools. Thanks to Yves Dorfsman for the
1526 Add two more environment variables for lease-change scripts:
1527 First, DNSMASQ_SUPPLIED_HOSTNAME; this is set to the hostname
1528 supplied by a client, even if the actual hostname used is
1529 over-ridden by dhcp-host or dhcp-ignore-names directives.
1530 Also DNSMASQ_RELAY_ADDRESS which gives the address of
1531 a DHCP relay, if used.
1532 Suggestions from Michael Rack.
1534 Fix regression which broke echo of relay-agent
1535 options. Thanks to Michael Rack for spotting this.
1537 Don't treat option 67 as being interchangeable with
1538 dhcp-boot parameters if it's specified as
1541 Make the code to call scripts on lease-change compile-time
1542 optional. It can be switched off by editing src/config.h
1543 or building with "make COPTS=-DNO_SCRIPT".
1545 Make the TFTP server cope with filenames from Windows/DOS
1546 which use '\' as pathname separator. Thanks to Ralf for
1549 Updated Polish translation. Thanks to Jan Psota.
1551 Warn if an IP address is duplicated in /etc/ethers. Thanks
1552 to Felix Schwarz for pointing this out.
1554 Teach --conf-dir to take an option list of file suffices
1555 which will be ignored when scanning the directory. Useful
1556 for backup files etc. Thanks to Helmut Hullen for the
1559 Add new DHCP option named tftpserver-address, which
1560 corresponds to the third argument of dhcp-boot. This
1561 allows the complete functionality of dhcp-boot to be
1562 replicated with dhcp-option. Useful when using
1565 Test which upstream nameserver to use every 10 seconds
1566 or 50 queries and not just when a query times out and
1567 is retried. This should improve performance when there
1568 is a slow nameserver in the list. Thanks to Joe for the
1571 Don't do any PXE processing, even for clients with the
1572 correct vendorclass, unless at least one pxe-prompt or
1573 pxe-service option is given. This stops dnsmasq
1574 interfering with proxy PXE subsystems when it is just
1575 the DHCP server. Thanks to Spencer Clark for spotting this.
1577 Limit the blocksize used for TFTP transfers to a value
1578 which avoids packet fragmentation, based on the MTU of the
1579 local interface. Many netboot ROMs can't cope with
1582 Honour dhcp-ignore configuration for PXE and proxy-PXE
1583 requests. Thanks to Niels Basjes for the bug report.
1585 Updated French translation. Thanks to Gildas Le Nadan.
1589 Fix security problem which allowed any host permitted to
1590 do TFTP to possibly compromise dnsmasq by remote buffer
1591 overflow when TFTP enabled. Thanks to Core Security
1592 Technologies and Iván Arce, Pablo Hernán Jorge, Alejandro
1593 Pablo Rodriguez, Martín Coco, Alberto Soliño Testa and
1594 Pablo Annetta. This problem has Bugtraq id: 36121
1597 Fix a problem which allowed a malicious TFTP client to
1598 crash dnsmasq. Thanks to Steve Grubb at Red Hat for
1599 spotting this. This problem has Bugtraq id: 36120 and
1604 Fix regression in 2.48 which disables the lease-change
1605 script. Thanks to Jose Luis Duran for spotting this.
1607 Log TFTP "file not found" errors. These were not logged,
1608 since a normal PXELinux boot generates many of them, but
1609 the lack of the messages seems to be more confusing than
1610 routinely seeing them when there is no real error.
1612 Update Spanish translation. Thanks to Chris Chatham.
1616 Archived the extensive, backwards, changelog to
1617 CHANGELOG.archive. The current changelog now runs from
1618 version 2.43 and runs conventionally.
1620 Fixed bug which broke binding of servers to physical
1621 interfaces when interface names were longer than four
1622 characters. Thanks to MURASE Katsunori for the patch.
1624 Fixed netlink code to check that messages come from the
1625 correct source, and not another userspace process. Thanks
1626 to Steve Grubb for the patch.
1628 Maintainability drive: removed bug and missing feature
1629 workarounds for some old platforms. Solaris 9, OpenBSD
1630 older than 4.1, Glibc older than 2.2, Linux 2.2.x and
1631 DBus older than 1.1.x are no longer supported.
1633 Don't read included configuration files more than once:
1634 allows complex configuration structures without problems.
1636 Mark log messages from the various subsystems in dnsmasq:
1637 messages from the DHCP subsystem now have the ident string
1638 "dnsmasq-dhcp" and messages from TFTP have ident
1639 "dnsmasq-tftp". Thanks to Olaf Westrik for the patch.
1641 Fix possible infinite DHCP protocol loop when an IP
1642 address nailed to a hostname (not a MAC address) and a
1643 host sometimes provides the name, sometimes not.
1645 Allow --addn-hosts to take a directory: all the files
1646 in the directory are read. Thanks to Phil Cornelius for
1649 Support --bridge-interface on all platforms, not just BSD.
1651 Added support for advanced PXE functions. It's now
1652 possible to define a prompt and menu options which will
1653 be displayed when a client PXE boots. It's also possible to
1654 hand-off booting to other boot servers. Proxy-DHCP, where
1655 dnsmasq just supplies the PXE information and another DHCP
1656 server does address allocation, is also allowed. See the
1657 --pxe-prompt and --pxe-service keywords. Thanks to
1658 Alkis Georgopoulos for the suggestion and Guilherme Moro
1659 and Michael Brown for assistance.
1661 Improvements to DHCP logging. Thanks to Tom Metro for
1664 Add ability to build dnsmasq without DHCP support. To do
1665 this, edit src/config.h or build with
1666 "make COPTS=-DNO_DHCP". Thanks to Mahavir Jain for the patch.
1668 Added --test command-line switch - syntax check
1669 configuration files only.
1671 Updated French translation. Thanks to Gildas Le Nadan.
1675 Updated French translation. Thanks to Gildas Le Nadan.
1677 Fixed interface enumeration code to work on NetBSD
1678 5.0. Thanks to Roy Marples for the patch.
1680 Updated config.h to use the same location for the lease
1681 file on NetBSD as the other *BSD variants. Also allow
1682 LEASEFILE and CONFFILE symbols to be overriden in CFLAGS.
1684 Handle duplicate address detection on IPv6 more
1685 intelligently. In IPv6, an interface can have an address
1686 which is not usable, because it is still undergoing DAD
1687 (such addresses are marked "tentative"). Attempting to
1688 bind to an address in this state returns an error,
1689 EADDRNOTAVAIL. Previously, on getting such an error,
1690 dnsmasq would silently abandon the address, and never
1691 listen on it. Now, it retries once per second for 20
1692 seconds before generating a fatal error. 20 seconds should
1693 be long enough for any DAD process to complete, but can be
1694 adjusted in src/config.h if necessary. Thanks to Martin
1695 Krafft for the bug report.
1697 Add DBus introspection. Patch from Jeremy Laine.
1699 Update Dbus configuration file. Patch from Colin Walters.
1701 http://bugs.freedesktop.org/show_bug.cgi?id=18961
1703 Support arbitrarily encapsulated DHCP options, suggestion
1704 and initial patch from Samium Gromoff. This is useful for
1705 (eg) gPXE, which expect all its private options to be
1706 encapsulated inside a single option 175. So, eg,
1708 dhcp-option = encap:175, 190, "iscsi-client0"
1709 dhcp-option = encap:175, 191, "iscsi-client0-secret"
1711 will provide iSCSI parameters to gPXE.
1713 Enhance --dhcp-match to allow testing of the contents of a
1714 client-sent option, as well as its presence. This
1715 application in mind for this is RFC 4578
1716 client-architecture specifiers, but it's generally useful.
1717 Joey Korkames suggested the enhancement.
1719 Move from using the IP_XMIT_IF ioctl to IP_BOUND_IF on
1720 OpenSolaris. Thanks to Bastian Machek for the heads-up.
1722 No longer complain about blank lines in
1723 /etc/ethers. Thanks to Jon Nelson for the patch.
1725 Fix binding of servers to physical devices, eg
1726 --server=/domain/1.2.3.4@eth0 which was broken from 2.43
1727 onwards unless --query-port=0 set. Thanks to Peter Naulls
1730 Reply to DHCPINFORM requests even when the supplied ciaddr
1731 doesn't fall in any dhcp-range. In this case it's not
1732 possible to supply a complete configuration, but
1733 individually-configured options (eg PAC) may be useful.
1735 Allow the source address of an alias to be a range:
1736 --alias=192.168.0.0,10.0.0.0,255.255.255.0 maps the whole
1737 subnet 192.168.0.0->192.168.0.255 to 10.0.0.0->10.0.0.255,
1739 --alias=192.168.0.10-192.168.0.40,10.0.0.0,255.255.255.0
1740 maps only the 192.168.0.10->192.168.0.40 region. Thanks to
1741 Ib Uhrskov for the suggestion.
1743 Don't dynamically allocate DHCP addresses which may break
1744 Windows. Addresses which end in .255 or .0 are broken in
1745 Windows even when using supernetting.
1746 --dhcp-range=192.168.0.1,192.168.1.254,255,255,254.0 means
1747 192.168.0.255 is a valid IP address, but not for Windows.
1748 See Microsoft KB281579. We therefore no longer allocate
1749 these addresses to avoid hard-to-diagnose problems.
1751 Update Polish translation. Thanks to Jan Psota.
1753 Delete the PID-file when dnsmasq shuts down. Note that by
1754 this time, dnsmasq is normally not running as root, so
1755 this will fail if the PID-file is stored in a root-owned
1756 directory; such failure is silently ignored. To take
1757 advantage of this feature, the PID-file must be stored in a
1758 directory owned and write-able by the user running
1763 Allow --bootp-dynamic to take a netid tag, so that it may
1764 be selectively enabled. Thanks to Olaf Westrik for the
1767 Remove ISC-leasefile reading code. This has been
1768 deprecated for a long time, and last time I removed it, it
1769 ended up going back by request of one user. This time,
1770 it's gone for good; otherwise it would need to be
1771 re-worked to support multiple domains (see below).
1773 Support DHCP clients in multiple DNS domains. This is a
1774 long-standing request. Clients are assigned to a domain
1775 based in their IP address.
1777 Add --dhcp-fqdn flag, which changes behaviour if DNS names
1778 assigned to DHCP clients. When this is set, there must be
1779 a domain associated with each client, and only
1780 fully-qualified domain names are added to the DNS. The
1781 advantage is that the only the FQDN needs to be unique,
1782 so that two or more DHCP clients can share a hostname, as
1783 long as they are in different domains.
1785 Set environment variable DNSMASQ_DOMAIN when invoking
1786 lease-change script. This may be useful information to
1787 have now that it's variable.
1789 Tighten up data-checking code for DNS packet
1790 handling. Thanks to Steve Dodd who found certain illegal
1791 packets which could crash dnsmasq. No memory overwrite was
1792 possible, so this is not a security issue beyond the DoS
1795 Update example config dhcp option 47, the previous
1796 suggestion generated an illegal, zero-length,
1797 option. Thanks to Matthias Andree for finding this.
1799 Rewrite hosts-file reading code to remove the limit of
1800 1024 characters per line. John C Meuser found this.
1802 Create a net-id tag with the name of the interface on
1803 which the DHCP request was received.
1805 Fixed minor memory leak in DBus code, thanks to Jeremy
1806 Laine for the patch.
1808 Emit DBus signals as the DHCP lease database
1809 changes. Thanks to Jeremy Laine for the patch.
1811 Allow for more that one MAC address in a dhcp-host
1812 line. This configuration tells dnsmasq that it's OK to
1813 abandon a DHCP lease of the fixed address to one MAC
1814 address, if another MAC address in the dhcp-host statement
1815 asks for an address. This is useful to give a fixed
1816 address to a host which has two network interfaces
1817 (say, a laptop with wired and wireless interfaces.)
1818 It's very important to ensure that only one interface
1819 at a time is up, since dnsmasq abandons the first lease
1820 and re-uses the address before the leased time has
1821 elapsed. John Gray suggested this.
1823 Tweak the response to a DHCP request packet with a wrong
1824 server-id when --dhcp-authoritative is set; dnsmasq now
1825 returns a DHCPNAK, rather than silently ignoring the
1826 packet. Thanks to Chris Marget for spotting this
1829 Add --cname option. This provides a limited alias
1830 function, usable for DHCP names. Thanks to AJ Weber for
1831 suggestions on this.
1833 Updated contrib/webmin with latest version from Neil
1836 Updated Polish translation. Thanks to Jan Psota.
1838 Correct the text names for DHCP options 64 and 65 to be
1839 "nis+-domain" and "nis+-servers".
1841 Updated Spanish translation. Thanks to Chris Chatham.
1843 Force re-reading of /etc/resolv.conf when an "interface
1848 Fix total DNS failure in release 2.44 unless --min-port
1849 specified. Thanks to Steven Barth and Grant Coady for
1850 bugreport. Also reject out-of-range port spec, which could
1851 break things too: suggestion from Gilles Espinasse.
1855 Fix crash when unknown client attempts to renew a DHCP
1856 lease, problem introduced in version 2.43. Thanks to
1857 Carlos Carvalho for help chasing this down.
1859 Fix potential crash when a host which doesn't have a lease
1860 does DHCPINFORM. Again introduced in 2.43. This bug has
1861 never been reported in the wild.
1863 Fix crash in netlink code introduced in 2.43. Thanks to
1864 Jean Wolter for finding this.
1866 Change implementation of min_port to work even if min-port
1869 Patch to enable compilation of latest Mac OS X. Thanks to
1872 Update Spanish translation. Thanks to Christopher Chatham.
1876 Updated Polish translation. Thanks to Jan Psota.
1878 Flag errors when configuration options are repeated
1881 Further tweaks for GNU/kFreeBSD
1883 Add --no-wrap to msgmerge call - provides nicer .po file
1886 Honour lease-time spec in dhcp-host lines even for
1887 BOOTP. The user is assumed to known what they are doing in
1888 this case. (Hosts without the time spec still get infinite
1889 leases for BOOTP, over-riding the default in the
1890 dhcp-range.) Thanks to Peter Katzmann for uncovering this.
1892 Fix problem matching relay-agent ids. Thanks to Michael
1893 Rack for the bug report.
1895 Add --naptr-record option. Suggestion from Johan
1898 Implement RFC 5107 server-id-override DHCP relay agent
1901 Apply patches from Stefan Kruger for compilation on
1902 Solaris 10 under Sun studio.
1904 Yet more tweaking of Linux capability code, to suppress
1905 pointless wingeing from kernel 2.6.25 and above.
1907 Improve error checking during startup. Previously, some
1908 errors which occurred during startup would be worked
1909 around, with dnsmasq still starting up. Some were logged,
1910 some silent. Now, they all cause a fatal error and dnsmasq
1911 terminates with a non-zero exit code. The errors are those
1912 associated with changing uid and gid, setting process
1913 capabilities and writing the pidfile. Thanks to Uwe
1914 Gansert and the Suse security team for pointing out
1915 this improvement, and Bill Reimers for good implementation
1918 Provide NO_LARGEFILE compile option to switch off largefile
1919 support when compiling against versions of uclibc which
1920 don't support it. Thanks to Stephane Billiart for the patch.
1922 Implement random source ports for interactions with
1923 upstream nameservers. New spoofing attacks have been found
1924 against nameservers which do not do this, though it is not
1925 clear if dnsmasq is vulnerable, since to doesn't implement
1926 recursion. By default dnsmasq will now use a different
1927 source port (and socket) for each query it sends
1928 upstream. This behaviour can suppressed using the
1929 --query-port option, and the old default behaviour
1930 restored using --query-port=0. Explicit source-port
1931 specifications in --server configs are still honoured.
1933 Replace the random number generator, for better
1934 security. On most BSD systems, dnsmasq uses the
1935 arc4random() RNG, which is secure, but on other platforms,
1936 it relied on the C-library RNG, which may be
1937 guessable and therefore allow spoofing. This release
1938 replaces the libc RNG with the SURF RNG, from Daniel
1939 J. Berstein's DJBDNS package.
1941 Don't attempt to change user or group or set capabilities
1942 if dnsmasq is run as a non-root user. Without this, the
1943 change from soft to hard errors when these fail causes
1944 problems for non-root daemons listening on high
1945 ports. Thanks to Patrick McLean for spotting this.
1947 Updated French translation. Thanks to Gildas Le Nadan.
1951 The changelog for version 2.42 and earlier is
1952 available in CHANGELOG.archive.
