17 | When assigning existing DHCP leases to intefaces by comparing |
18 | networks, handle the case that two or more interfaces have the | |
19 | same network part, but different prefix lengths (favour the | |
20 | longer prefix length.) Thanks to Lung-Pin Chang for the | |
21 | patch. | |

24 | version 2.71 |
25 | Subtle change to error handling to help DNSSEC validation | |
26 | when servers fail to provide NODATA answers for | |
27 | non-existent DS records. | |
28 | ||
29 | Tweak code which removes DNSSEC records from answers when | |
30 | not required. Fixes broken answers when additional section | |
31 | has real records in it. Thanks to Marco Davids for the bug | |
32 | report. | |
33 | ||
34 | Fix DNSSEC validation of ANY queries. Thanks to Marco Davids | |
35 | for spotting that too. | |

b692f234 SK |
37 | Fix total DNS failure and 100% CPU use if cachesize set to zero, |
38 | regression introduced in 2.69. Thanks to James Hunt and | |
39 | the Ubuntu crowd for assistance in fixing this. | |

42 | version 2.70 |
43 | Fix crash, introduced in 2.69, on TCP request when dnsmasq | |
44 | compiled with DNSSEC support, but running without DNSSEC | |
45 | enabled. Thanks to Manish Sing for spotting that one. | |

51 | version 2.69 |
52 | Implement dynamic interface discovery on *BSD. This allows | |
53 | the contructor: syntax to be used in dhcp-range for DHCPv6 | |
54 | on the BSD platform. Thanks to Matthias Andree for | |
55 | valuable research on how to implement this. | |

ae76242f SK |
60 | Fix missing RA RDNS option with configuration like |
61 | --dhcp-option=option6:23,[::] Thanks to Tsachi Kimeldorfer | |
62 | for spotting the problem. | |
63 | ||
c3a04081 SK |
64 | Add [fd00::] and [fe80::] as special addresses in DHCPv6 |
65 | options, analogous to [::]. [fd00::] is replaced with the | |
66 | actual ULA of the interface on the machine running | |
67 | dnsmasq, [fe80::] with the link-local address. | |
68 | Thanks to Tsachi Kimeldorfer for championing this. | |
69 | ||
613d6c52 SK |
70 | DNSSEC validation and caching. Dnsmasq needs to be |
71 | compiled with this enabled, with | |
72 | ||
73 | make dnsmasq COPTS=-DHAVE_DNSSEC | |
74 | ||
75 | this add dependencies on the nettle crypto library and the | |
76 | gmp maths library. It's possible to have these linked | |
77 | statically with | |
78 | ||
79 | make dnsmasq COPTS='-DHAVE_DNSSEC -DHAVE_DNSSEC_STATIC' | |
80 | ||
198d940a SK |
81 | which bloats the dnsmasq binary, but saves the size of |
82 | the shared libraries which are much bigger. | |
83 | ||
613d6c52 SK |
84 | To enable, DNSSEC, you will need a set of |
85 | trust-anchors. Now that the TLDs are signed, this can be | |
86 | the keys for the root zone, and for convenience they are | |
87 | included in trust-anchors.conf in the dnsmasq | |
88 | distribution. You should of course check that these are | |
89 | legitimate and up-to-date. So, adding | |
90 | ||
91 | conf-file=/path/to/trust-anchors.conf | |
92 | dnssec | |
1ee9be4c | 93 | |
613d6c52 SK |
94 | to your config is all thats needed to get things |
95 | working. The upstream nameservers have to be DNSSEC-capable | |
96 | too, of course. Many ISP nameservers aren't, but the | |
97 | Google public nameservers (8.8.8.8 and 8.8.4.4) are. | |
98 | When DNSSEC is configured, dnsmasq validates any queries | |
99 | for domains which are signed. Query results which are | |
100 | bogus are replaced with SERVFAIL replies, and results | |
101 | which are correctly signed have the AD bit set. In | |
102 | addition, and just as importantly, dnsmasq supplies | |
103 | correct DNSSEC information to clients which are doing | |
104 | their own validation, and caches DNSKEY, DS and RRSIG | |
105 | records, which significantly improve the performance of | |
106 | downstream validators. Setting --log-queries will show | |
107 | DNSSEC in action. | |
108 | ||
198d940a SK |
109 | If a domain is returned from an upstream nameserver without |
110 | DNSSEC signature, dnsmasq by default trusts this. This | |
111 | means that for unsigned zone (still the majority) there | |
112 | is effectively no cost for having DNSSEC enabled. Of course | |
113 | this allows an attacker to replace a signed record with a | |
114 | false unsigned record. This is addressed by the | |
115 | --dnssec-check-unsigned flag, which instructs dnsmasq | |
116 | to prove that an unsigned record is legitimate, by finding | |
117 | a secure proof that the zone containing the record is not | |
118 | signed. Doing this has costs (typically one or two extra | |
119 | upstream queries). It also has a nasty failure mode if | |
120 | dnsmasq's upstream nameservers are not DNSSEC capable. | |
121 | Without --dnssec-check-unsigned using such an upstream | |
122 | server will simply result in not queries being validated; | |
123 | with --dnssec-check-unsigned enabled and a | |
124 | DNSSEC-ignorant upstream server, _all_ queries will fail. | |
125 | ||
126 | Note that DNSSEC requires that the local time is valid and | |
127 | accurate, if not then DNSSEC validation will fail. NTP | |
128 | should be running. This presents a problem for routers | |
129 | without a battery-backed clock. To set the time needs NTP | |
130 | to do DNS lookups, but lookups will fail until NTP has run. | |
131 | To address this, there's a flag, --dnssec-no-timecheck | |
132 | which disables the time checks (only) in DNSSEC. When dnsmasq | |
133 | is started and the clock is not synced, this flag should | |
134 | be used. As soon as the clock is synced, SIGHUP dnsmasq. | |
135 | The SIGHUP clears the cache of partially-validated data and | |
136 | resets the no-timecheck flag, so that all DNSSEC checks | |
137 | henceforward will be complete. | |
138 | ||
613d6c52 SK |
139 | The development of DNSSEC in dnsmasq was started by |
140 | Giovanni Bajo, to whom huge thanks are owed. It has been | |
141 | supported by Comcast, whose techfund grant has allowed for | |
142 | an invaluable period of full-time work to get it to | |
143 | a workable state. | |
144 | ||
de73a497 | 145 | Add --rev-server. Thanks to Dave Taht for suggesting this. |
7b1eae4f SK |
146 | |
147 | Add --servers-file. Allows dynamic update of upstream servers | |
148 | full access to configuration. | |
de73a497 | 149 | |
c8a80487 SK |
150 | Add --local-service. Accept DNS queries only from hosts |
151 | whose address is on a local subnet, ie a subnet for which | |
152 | an interface exists on the server. This option | |
f00690f9 | 153 | only has effect if there are no --interface --except-interface, |
c8a80487 SK |
154 | --listen-address or --auth-server options. It is intended |
155 | to be set as a default on installation, to allow | |
156 | unconfigured installations to be useful but also safe from | |
157 | being used for DNS amplification attacks. | |
158 | ||
604f7598 SK |
159 | Fix crashes in cache_get_cname_target() when dangling CNAMEs |
160 | encountered. Thanks to Andy and the rt-n56u project for | |
161 | find this and helping to chase it down. | |
162 | ||
10068600 SK |
163 | Fix wrong RCODE in authoritative DNS replies to PTR queries. The |
164 | correct answer was included, but the RCODE was set to NXDOMAIN. | |
165 | Thanks to Craig McQueen for spotting this. | |
166 | ||
198d940a SK |
167 | Make statistics available as DNS queries in the .bind TLD as |
168 | well as logging them. | |
169 | ||
c8a80487 | 170 | |
376d48c7 SK |
171 | version 2.68 |
172 | Use random addresses for DHCPv6 temporary address | |
173 | allocations, instead of algorithmically determined stable | |
174 | addresses. | |
175 | ||
176 | Fix bug which meant that the DHCPv6 DUID was not available | |
177 | in DHCP script runs during the lifetime of the dnsmasq | |
178 | process which created the DUID de-novo. Once the DUID was | |
179 | created and stored in the lease file and dnsmasq | |
180 | restarted, this bug disappeared. | |
181 | ||
182 | Fix bug introduced in 2.67 which could result in erroneous | |
183 | NXDOMAIN returns to CNAME queries. | |
184 | ||
185 | Fix build failures on MacOS X and openBSD. | |
186 | ||
187 | Allow subnet specifications in --auth-zone to be interface | |
188 | names as well as address literals. This makes it possible | |
189 | to configure authoritative DNS when local address ranges | |
190 | are dynamic and works much better than the previous | |
191 | work-around which exempted contructed DHCP ranges from the | |
192 | IP address filtering. As a consequence, that work-around | |
193 | is removed. Under certain circumstances, this change wil | |
194 | break existing configuration: if you're relying on the | |
195 | contructed-range exception, you need to change --auth-zone | |
196 | to specify the same interface as is used to construct your | |
197 | DHCP ranges, probably with a trailing "/6" like this: | |
198 | --auth-zone=example.com,eth0/6 to limit the addresses to | |
199 | IPv6 addresses of eth0. | |
dd9d9ce5 SK |
200 | |
201 | Fix problems when advertising deleted IPv6 prefixes. If | |
202 | the prefix is deleted (rather than replaced), it doesn't | |
203 | get advertised with zero preferred time. Thanks to Tsachi | |
204 | for the bug report. | |
25439064 SK |
205 | |
206 | Fix segfault with some locally configured CNAMEs. Thanks | |
207 | to Andrew Childs for spotting the problem. | |
208 | ||
209 | Fix memory leak on re-reading /etc/hosts and friends, | |
210 | introduced in 2.67. | |
2329bef5 SK |
211 | |
212 | Check the arrival interface of incoming DNS and TFTP | |
213 | requests via IPv6, even in --bind-interfaces mode. This | |
214 | isn't possible for IPv4 and can generate scary warnings, | |
215 | but as it's always possible for IPv6 (the API always | |
216 | exists) then we should do it always. | |
4c82efc5 VG |
217 | |
218 | Tweak the rules on prefix-lengths in --dhcp-range for | |
219 | IPv6. The new rule is that the specified prefix length | |
220 | must be larger than or equal to the prefix length of the | |
221 | corresponding address on the local interface. | |
222 | ||

797a7afb GT |
224 | version 2.67 |
225 | Fix crash if upstream server returns SERVFAIL when | |
226 | --conntrack in use. Thanks to Giacomo Tazzari for finding | |
227 | this and supplying the patch. | |
aa63a21c SK |
228 | |
229 | Repair regression in 2.64. That release stopped sending | |
230 | lease-time information in the reply to DHCPINFORM | |
231 | requests, on the correct grounds that it was a standards | |
232 | violation. However, this broke the dnsmasq-specific | |
233 | dhcp_lease_time utility. Now, DHCPINFORM returns | |
234 | lease-time only if it's specifically requested | |
235 | (maintaining standards) and the dhcp_lease_time utility | |
236 | has been taught to ask for it (restoring functionality). | |
86e92f99 SK |
237 | |
238 | Fix --dhcp-match, --dhcp-vendorclass and --dhcp-userclass | |
239 | to work with BOOTP and well as DHCP. Thanks to Peter | |
240 | Korsgaard for spotting the problem. | |
2bb73af7 SK |
241 | |
242 | Add --synth-domain. Thanks to Vishvananda Ishaya for | |
243 | suggesting this. | |
d5052fb2 SK |
244 | |
245 | Fix failure to compile ipset.c if old kernel headers are | |
246 | in use. Thanks to Eugene Rudoy for pointing this out. | |
3f2873d4 SK |
247 | |
248 | Handle IPv4 interface-address labels in Linux. These are | |
249 | often used to emulate the old IP-alias addresses. Before, | |
250 | using --interface=eth0 would service all the addresses of | |
251 | eth0, including ones configured as aliases, which appear | |
252 | in ifconfig as eth0:0. Now, only addresses with the label | |
253 | eth0 are active. This is not backwards compatible: if you | |
254 | want to continue to bind the aliases too, you need to add | |
255 | eg. --interface=eth0:0 to the config. | |
797a7afb | 256 | |
cfcad42f SK |
257 | Fix "failed to set SO_BINDTODEVICE on DHCP socket: Socket |
258 | operation on non-socket" error on startup with | |
259 | configurations which have exactly one --interface option | |
260 | and do RA but _not_ DHCPv6. Thanks to Trever Adams for the | |
261 | bug report. | |
797a7afb | 262 | |
115ac3e4 SK |
263 | Generalise --interface-name to cope with IPv6 addresses |
264 | and multiple addresses per interface per address family. | |
265 | ||
3e8ed78b SK |
266 | Fix option parsing for --dhcp-host, which was generating a |
267 | spurious error when all seven possible items were | |
268 | included. Thanks to Zhiqiang Wang for the bug report. | |
baa80ae5 SK |
269 | |
270 | Remove restriction on prefix-length in --auth-zone. Thanks | |
271 | to Toke Hoiland-Jorgensen for suggesting this. | |
272 | ||
0da5e897 MSB |
273 | Log when the maximum number of concurrent DNS queries is |
274 | reached. Thanks to Marcelo Salhab Brogliato for the patch. | |
275 | ||
e2ba0df2 SK |
276 | If wildcards are used in --interface, don't assume that |
277 | there will only ever be one available interface for DHCP | |
278 | just because there is one at start-up. More may appear, so | |
279 | we can't use SO_BINDTODEVICE. Thanks to Natrio for the bug | |
280 | report. | |
281 | ||
b4b93080 SK |
282 | Increase timeout/number of retries in TFTP to accomodate |
283 | AudioCodes Voice Gateways doing streaming writes to flash. | |
284 | Thanks to Damian Kaczkowski for spotting the problem. | |
285 | ||
625ac28c | 286 | Fix crash with empty DHCP string options when adding zero |
3953dcc7 | 287 | terminator. Thanks to Patrick McLean for the bug report. |
625ac28c | 288 | |
d859ca2f KM |
289 | Allow hostnames to start with a number, as allowed in |
290 | RFC-1123. Thanks to Kyle Mestery for the patch. | |
291 | ||
3f3adae6 RM |
292 | Fixes to DHCP FQDN option handling: don't terminate FQDN |
293 | if domain not known and allow a FQDN option with blank | |
294 | name to request that a FQDN option is returned in the | |
295 | reply. Thanks to Roy Marples for the patch. | |

d9fb0be8 SK |
297 | Make --clear-on-reload apply to setting upstream servers |
298 | via DBus too. | |
299 | ||
ef1a94ab SK |
300 | When the address which triggered the construction of an |
301 | advertised IPv6 prefix disappears, continue to advertise | |
302 | the prefix for up to 2 hours, with the preferred lifetime | |
303 | set to zero. This satisfies RFC 6204 4.3 L-13 and makes | |
304 | things work better if a prefix disappears without being | |
305 | deprecated first. Thanks to Uwe Schindler for persuasively | |
306 | arguing for this. | |

871d4562 SK |
311 | Support RFC-4242 information-refresh-time options in the |
312 | reply to DHCPv6 information-request. The lease time of the | |

2937f8a0 SK |
319 | Provide independent control over which interfaces get TFTP |
320 | service. If enable-tftp is given a list of interfaces, then TFTP | |
321 | is provided on those. Without the list, the previous behaviour | |
322 | (provide TFTP to the same interfaces we provide DHCP to) | |
323 | is retained. Thanks to Lonnie Abelbeck for the suggestion. | |
324 | ||

370 | Avoid treating a --dhcp-host which has an IPv6 address |

333b2ceb SK |
379 | version 2.66 |
380 | Add the ability to act as an authoritative DNS | |
381 | server. Dnsmasq can now answer queries from the wider 'net | |
382 | with local data, as long as the correct NS records are set | |
383 | up. Only local data is provided, to avoid creating an open | |
384 | DNS relay. Zone transfer is supported, to allow secondary | |
385 | servers to be configured. | |
386 | ||
387 | Add "constructed DHCP ranges" for DHCPv6. This is intended | |
388 | for IPv6 routers which get prefixes dynamically via prefix | |
389 | delegation. With suitable configuration, stateful DHCPv6 | |
390 | and RA can happen automatically as prefixes are delegated | |
391 | and then deprecated, without having to re-write the | |
392 | dnsmasq configuration file or restart the daemon. Thanks to | |
393 | Steven Barth for extensive testing and development work on | |
394 | this idea. | |

400 | Add code to make behaviour for TCP DNS requests that same | |
401 | as for UDP requests, when a request arrives for an allowed | |
402 | address, but via a banned interface. This change is only | |
403 | active on Linux, since the relevant API is missing (AFAIK) | |
404 | on other platforms. Many thanks to Tomas Hozza for | |

433 | Handle the situation where libc headers define |

12d71ed2 SK |
463 | Finesse the check for /etc/hosts names which conflict with |
464 | DHCP names. Previously a name/address pair in /etc/hosts | |
465 | which didn't match the name/address of a DHCP lease would | |
466 | generate a warning. Now that only happesn if there is not | |
467 | also a match. This allows multiple addresses for a name in | |
468 | /etc/hosts with one of them assigned via DHCP. | |

495 | Set SO_REUSEADDRESS and SO_V6ONLY options on the DHCPv6 |
496 | socket, this allows multiple instances of dnsmasq on a | |

8bc4cece SK |
545 | Remove the interface:<interface> argument in --dhcp-range, and |
546 | the interface argument to --enable-tftp. These were a | |
547 | still-born attempt to allow automatic isolated | |
548 | configuration by libvirt, but have never (to my knowledge) | |
549 | been used, had very strange semantics, and have been | |
550 | superceded by other mechanisms. | |

604 | version 2.61 |
605 | Re-write interface discovery code on *BSD to use | |

607 | and allows us to find the prefix length for IPv6 | |
608 | addresses. | |

01d1b8dd SK |
610 | Add ra-names, ra-stateless and slaac keywords for DHCPv6. |
611 | Dnsmasq can now synthesise AAAA records for dual-stack | |
612 | hosts which get IPv6 addresses via SLAAC. It is also now | |

8643ec7f SK |
619 | Explicity send DHCPv6 replies to the correct port, instead |
620 | of relying on clients to send requests with the correct | |

8358e0f4 | 622 | this wrong. Thanks to Conrad Kostecki for help tracking |
8643ec7f | 623 | this down. |
eabc6dd7 | 624 | |
8643ec7f SK |
625 | Send a preference value of 255 in DHCPv6 replies when |

634 | Invoke the DHCP script with action "tftp" when a TFTP file |
635 | transfer completes. The size of the file, address to which | |
636 | it was sent and complete pathname are supplied. Note that | |
637 | version 2.60 introduced some script incompatibilties | |
638 | associated with DHCPv6, and this is a further change. To | |
639 | be safe, scripts should ignore unknown actions, and if | |
640 | not IPv6-aware, should exit if the environment | |
641 | variable DNSMASQ_IAID is set. The use-case for this is | |
642 | to track netboot/install. Suggestion from Shantanu | |
643 | Gadgil. | |
644 | ||
645 | Update contrib/port-forward/dnsmasq-portforward to reflect | |
646 | the above. | |

653 | Arrange that addresses specified with --listen-address | |
654 | work even if there is no interface carrying the | |
655 | address. This is chiefly useful for IPv4 loopback | |
656 | addresses, where any address in 127.0.0.0/8 is a valid | |
657 | loopback address, but normally only 127.0.0.1 appears on | |
658 | the lo interface. Thanks to Mathieu Trudel-Lapierre for | |
659 | the idea and initial patch. | |

664 | ||
c8257540 SK |
665 | Add a new DHCP lease time keyword, "deprecated" for |
666 | --dhcp-range. This is only valid for IPv6, and sets the | |
667 | preffered lease time for both DHCP and RA to zero. The | |
668 | effect is that clients can continue to use the address | |
669 | for existing connections, but new connections will use | |
670 | other addresses, if they exist. This makes hitless | |
671 | renumbering at least possible. | |
672 | ||
673 | Fix bug in address6_available() which caused DHCPv6 lease | |
8358e0f4 | 674 | aquisition to fail if more than one dhcp-range in use. |

715 | Fix DHCP when using --listen-address with an IP address | |
716 | which is not the primary address of an interface. | |
717 | ||
718 | Add --dhcp-client-update option. | |
719 | ||
720 | Add Lua integration. Dnsmasq can now execute a DHCP | |
721 | lease-change script written in Lua. This needs to be | |
722 | enabled at compile time by setting HAVE_LUASCRIPT in | |
723 | src/config.h or running "make COPTS=-DHAVE_LUASCRIPT" | |
724 | Thanks to Jan-Piet Mens for the idea and proof-of-concept | |
725 | implementation. | |
726 | ||
727 | Tidied src/config.h to distinguish between | |
728 | platform-dependent compile-time options which are selected | |
729 | automatically, and builder-selectable compile time | |
730 | options. Document the latter better, and describe how to | |
731 | set them from the make command line. | |
732 | ||
733 | Tidied up IPPROTO_IP/SOL_IP (and IPv6 equivalent) | |
734 | confusion. IPPROTO_IP works everywhere now. | |

751d6f4a SK |
753 | Allow the TFP server or boot server in --pxe-service, to |
754 | be a domain name instead of an IP address. This allows for | |
755 | round-robin to multiple servers, in the same way as | |
756 | --dhcp-boot. A good suggestion from Cristiano Cumer. | |
757 | ||
fdacfb01 SK |
758 | Support BUILDDIR variable in the Makefile. Allows builds |
759 | for multiple archs from the same source tree with eg. | |
760 | make BUILDDIR=linux (relative to dnsmasq tree) | |
761 | make BUILDDIR=/tmp/openbsd (absolute path) | |
e5ffdb9c | 762 | If BUILDDIR is not set, compilation happens in the src |
b36ae194 SK |
763 | directory, as before. Suggestion from Mark Mitchell. |
764 | ||
fdacfb01 SK |
765 | Support DHCPv6. Support is there for the sort of things |
766 | the existing v4 server does, including tags, options, | |
767 | static addresses and relay support. Missing is prefix | |
768 | delegation, which is probably not required in the dnsmasq | |
769 | niche, and an easy way to accept prefix delegations from | |
770 | an upstream DHCPv6 server, which is. Future plans include | |
771 | support for DHCPv6 router option and MAC address option | |
772 | (to make selecting clients by MAC address work like IPv4). | |
773 | These will be added as the standards mature. | |
774 | This code has been tested, but this is the first release, | |
775 | so don't bet the farm on it just yet. Many thanks to all | |
776 | testers who have got it this far. | |
1adadf58 | 777 | |
ac8540c3 SK |
778 | Support IPv6 router advertisements. This is a |
779 | simple-minded implementation, aimed at providing the | |
780 | vestigial RA needed to go alongside IPv6. Is picks up | |
781 | configuration from the DHCPv6 conf, and should just need | |
782 | enabling with --enable-ra. | |

552af8b9 SK |
784 | Fix long-standing wrinkle with --localise-queries that |

74c95c25 | 794 | version 2.59 |
c72daea8 SK |
795 | Fix regression in 2.58 which caused failure to start up |
796 | with some combinations of dnsmasq config and IPv6 kernel | |
797 | network config. Thanks to Brielle Bruns for the bug | |
798 | report. | |
799 | ||
800 | Improve dnsmasq's behaviour when network interfaces are | |
801 | still doing duplicate address detection (DAD). Previously, | |
802 | dnsmasq would wait up to 20 seconds at start-up for the | |
803 | DAD state to terminate. This is broken for bridge | |
804 | interfaces on recent Linux kernels, which don't start DAD | |
805 | until the bridge comes up, and so can take arbitrary | |
806 | time. The new behaviour lets dnsmasq poll for an arbitrary | |
807 | time whilst providing service on other interfaces. Thanks | |
808 | to Stephen Hemminger for pointing out the problem. | |
74c95c25 SK |

815 | Don't include a zero terminator at the end of messages | |
816 | sent to /dev/log when /dev/log is a datagram socket. | |
817 | Thanks to Didier Rabound for spotting the problem. | |
818 | ||
819 | Add --dhcp-sequential-ip flag, to force allocation of IP | |
820 | addresses in ascending order. Note that the default | |
821 | pseudo-random mode is in general better but some | |
822 | server-deployment applications need this. | |
823 | ||
824 | Fix problem where a server-id of 0.0.0.0 is sent to a | |
825 | client when a dhcp-relay is in use if a client renews a | |
826 | lease after dnsmasq restart and before any clients on the | |
827 | subnet get a new lease. Thanks to Mike Ruiz for assistance | |
828 | in chasing this one down. | |
829 | ||
830 | Don't return NXDOMAIN to an AAAA query if we have CNAME | |
831 | which points to an A record only: NODATA is the correct | |
832 | reply in this case. Thanks to Tom Fernandes for spotting | |
833 | the problem. | |
834 | ||
835 | Relax the need to supply a netmask in --dhcp-range for | |
836 | networks which use a DHCP relay. Whilst this is still | |
837 | desireable, in the absence of a netmask dnsmasq will use | |
838 | a default based on the class (A, B, or C) of the address. | |
839 | This should at least remove a cause of mysterious failure | |
840 | for people using RFC1918 addresses and relays. | |
841 | ||
842 | Add support for Linux conntrack connection marking. If | |
843 | enabled with --conntrack, the connection mark for incoming | |
844 | DNS queries will be copied to the outgoing connections | |
845 | used to answer those queries. This allows clever firewall | |
846 | and accounting stuff. Only available if dnsmasq is | |
847 | compiled with HAVE_CONNTRACK and adds a dependency on | |
848 | libnetfilter-conntrack. Thanks to Ed Wildgoose for the | |
849 | initial idea, testing and sponsorship of this function. | |
850 | ||
851 | Provide a sane error message when someone attempts to | |
852 | match a tag in --dhcp-host. | |
853 | ||
854 | Tweak the behaviour of --domain-needed, to avoid problems | |
855 | with recursive nameservers downstream of dnsmasq. The new | |
856 | behaviour only stops A and AAAA queries, and returns | |
857 | NODATA rather than NXDOMAIN replies. | |
858 | ||
859 | Efficiency fix for very large DHCP configurations, thanks | |
860 | to James Gartrell and Mike Ruiz for help with this. | |
861 | ||
862 | Allow the TFTP-server address in --dhcp-boot to be a | |
863 | domain-name which is looked up in /etc/hosts. This can | |
864 | give multiple IP addresses which are used round-robin, | |
865 | thus doing TFTP server load-balancing. Thanks to Sushil | |
866 | Agrawal for the patch. | |
867 | ||
868 | When two tagged dhcp-options for a particular option | |
869 | number are both valid, use the one which is valid without | |
870 | a tag from the dhcp-range. Allows overriding of the value | |
871 | of a DHCP option for a particular host as well as | |
872 | per-network values. So | |
873 | --dhcp-range=set:interface1,...... | |
874 | --dhcp-host=set:myhost,..... | |
875 | --dhcp-option=tag:interface1,option:nis-domain,"domain1" | |
876 | --dhcp-option=tag:myhost,option:nis-domain,"domain2" | |
877 | will set the NIS-domain to domain1 for hosts in the range, but | |
878 | override that to domain2 for a particular host. | |
879 | ||
880 | Fix bug which resulted in truncated files and timeouts for | |
881 | some TFTP transfers. The bug only occurs with netascii | |
882 | transfers and needs an unfortunate relationship between | |
883 | file size, blocksize and the number of newlines in the | |
884 | last block before it manifests itself. Many thanks to | |
885 | Alkis Georgopoulos for spotting the problem and providing | |
886 | a comprehensive test-case. | |
887 | ||
888 | Fix regression in TFTP server on *BSD platforms introduced | |
889 | in version 2.56, due to confusion with sockaddr | |
de604c18 | 890 | length. Many thanks to Loic Pefferkorn for finding this. |
7de060b0 SK |
891 | |
892 | Support scope-ids in IPv6 addresses of nameservers from | |
893 | /etc/resolv.conf and in --server options. Eg | |
894 | nameserver fe80::202:a412:4512:7bbf%eth0 or | |
895 | server=fe80::202:a412:4512:7bbf%eth0. Thanks to | |
896 | Michael Stapelberg for the suggestion. | |
897 | ||
898 | Update Polish translation, thanks to Jan Psota. | |
899 | ||
900 | Update French translation. Thanks to Gildas Le Nadan. | |

572b41eb SK |
903 | version 2.57 |
904 | Add patches to allow build under Android. | |
905 | ||
906 | Provide our own header for the DNS protocol, rather than | |
907 | relying on arpa/nameser.h. This has proved more or less | |
908 | defective over the years and the final straw is that it's | |
909 | effectively empty on Android. | |
910 | ||
911 | Fix regression in 2.56 which caused hex constants in | |
912 | configuration to be rejected if they contain the '*' | |
913 | wildcard. | |
914 | ||
915 | Correct wrong casts of arguments to ctype.h functions, | |
916 | isdigit(), isxdigit() etc. Thanks to Matthias Andree for | |
917 | spotting this. | |
918 | ||
919 | Allow build with IDN support independently from i18n. | |
920 | IDN support continues to be included automatically | |
921 | when i18n is included. | |
922 | 'make COPTS=-DHAVE_IDN' is the magic incantation. | |
923 | ||
924 | Modify check on extraneous command line junk (added in | |
925 | 2.56) so that it doesn't complain about extra _empty_ | |
926 | arguments. Otherwise this breaks libvirt. | |
927 | ||
928 | ||
28866e95 SK |
929 | version 2.56 |
930 | Add a patch to allow dnsmasq to get interface names right in a | |
931 | Solaris zone. Thanks to Dj Padzensky for this. | |
932 | ||
933 | Improve data-type parsing heuristics so that | |
934 | --dhcp-option=option:domain-search,. | |
935 | treats the value as a string and not an IP address. | |
936 | Thanks to Clemens Fischer for spotting that. | |
937 | ||
938 | Add IPv6 support to the TFTP server. Many thanks to Jan | |
939 | 'RedBully' Seiffert for the patches. | |
940 | ||
941 | Log DNS queries at level LOG_INFO, rather then | |
942 | LOG_DEBUG. This makes things consistent with DHCP | |
943 | logging. Thanks to Adam Pribyl for spotting the problem. | |
944 | ||
945 | Ensure that dnsmasq terminates cleanly when using | |
946 | --syslog-async even if it cannot make a connection to the | |
947 | syslogd. | |
948 | ||
949 | Add --add-mac option. This is to support currently | |
950 | experimental DNS filtering facilities. Thanks to Benjamin | |
951 | Petrin for the orignal patch. | |
952 | ||
953 | Fix bug which meant that tags were ignored in dhcp-range | |
954 | configuration specifying PXE-proxy service. Thanks to | |
955 | Cristiano Cumer for spotting this. | |
956 | ||
957 | Raise an error if there is extra junk, not part of an | |
958 | option, on the command line. | |
959 | ||
960 | Flag a couple of log messages in cache.c as coming from | |
961 | the DHCP subsystem. Thanks to Olaf Westrik for the patch. | |
962 | ||
963 | Omit timestamps from logs when a) logging to stderr and | |
964 | b) --keep-in-forground is set. The logging facility on the | |
965 | other end of stderr can be assumned to supply them. Thanks | |
966 | to John Hallam for the patch. | |
967 | ||
968 | Don't complain about strings longer than 255 characters in | |
969 | --txt-record, just split the long strings into 255 | |
970 | character chunks instead. | |
971 | ||
972 | Fix crash on double-free. This bug can only happen when | |
973 | dhcp-script is in use and then only in rare circumstances | |
974 | triggered by high DHCP transaction rate and a slow | |
975 | script. Thanks to Ferenc Wagner for finding the problem. | |
976 | ||
977 | Only log that a file has been sent by TFTP after the | |
978 | transfer has completed succesfully. | |
979 | ||
980 | A good suggestion from Ferenc Wagner: extend | |
981 | the --domain option to allow this sort of thing: | |
982 | --domain=thekelleys.org.uk,192.168.0.0/24,local | |
983 | which automatically creates | |
984 | --local=/thekelleys.org.uk/ | |
985 | --local=/0.168.192.in-addr.arpa/ | |
986 | ||
987 | Tighten up syntax checking of hex contants in the config | |
988 | file. Thanks to Fred Damen for spotting this. | |
989 | ||
990 | Add dnsmasq logo/icon, contributed by Justin Swift. Many | |
991 | thanks for that. | |
992 | ||
993 | Never cache DNS replies which have the 'cd' bit set, or | |
994 | which result from queries forwarded with the 'cd' bit | |
995 | set. The 'cd' bit instructs a DNSSEC validating server | |
996 | upstream to ignore signature failures and return replies | |
997 | anyway. Without this change it's possible to pollute the | |
998 | dnsmasq cache with bad data by making a query with the | |
999 | 'cd' bit set and subsequent queries would return this data | |
1000 | without its being marked as suspect. Thanks to Anders | |
1001 | Kaseorg for pointing out this problem. | |
1002 | ||
1003 | Add --proxy-dnssec flag, for compliance with RFC | |
1004 | 4035. Dnsmasq will now clear the 'ad' bit in answers returned | |
1005 | from upstream validating nameservers unless this option is | |
1006 | set. | |
1007 | ||
1008 | Allow a filename of "-" for --conf-file to read | |
1009 | stdin. Suggestion from Timothy Redaelli. | |
1010 | ||
1011 | Rotate the order of SRV records in replies, to provide | |
1012 | round-robin load balancing when all the priorities are | |
1013 | equal. Thanks to Peter McKinney for the suggestion. | |
1014 | ||
1015 | Edit | |
1016 | contrib/MacOSX-launchd/uk.org.thekelleys.dnsmasq.plist | |
1017 | so that it doesn't log all queries to a file by | |
1018 | default. Thanks again to Peter McKinney. | |
1019 | ||
1020 | By default, setting an IPv4 address for a domain but not | |
1021 | an IPv6 address causes dnsmasq to return | |
1022 | an NODATA reply for IPv6 (or vice-versa). So | |
1023 | --address=/google.com/1.2.3.4 stops IPv6 queries for | |
1024 | *google.com from being forwarded. Make it possible to | |
1025 | override this behaviour by defining the sematics if the | |
1026 | same domain appears in both --server and --address. | |
1027 | In that case, the --address has priority for the address | |
1028 | family in which is appears, but the --server has priority | |
1029 | of the address family which doesn't appear in --adddress | |
1030 | So: | |
1031 | --address=/google.com/1.2.3.4 | |
1032 | --server=/google.com/# | |
1033 | will return 1.2.3.4 for IPv4 queries for *.google.com but | |
1034 | forward IPv6 queries to the normal upstream nameserver. | |
1035 | Similarly when setting an IPv6 address | |
1036 | only this will allow forwarding of IPv4 queries. Thanks to | |
1037 | William for pointing out the need for this. | |
1038 | ||
1039 | Allow more than one --dhcp-optsfile and --dhcp-hostsfile | |
1040 | and make them understand directories as arguments in the | |
1041 | same way as --addn-hosts. Suggestion from John Hanks. | |
1042 | ||
1043 | Ignore rebinding requests for leases we don't know | |
1044 | about. Rebind is broadcast, so we might get to overhear a | |
1045 | request meant for another DHCP server. NAKing this is | |
1046 | wrong. Thanks to Brad D'Hondt for assistance with this. | |
1047 | ||
572b41eb SK |
1048 | Fix cosmetic bug which produced strange output when |
1049 | dumping cache statistics with some configurations. Thanks | |
1050 | to Fedor Kozhevnikov for spotting this. | |

c52e1897 | 1056 | |
28866e95 SK |
1057 | Fix crash in netlink_multicast(). Thanks to Arno Wald for |

c52e1897 | 1059 | |
28866e95 SK |
1060 | Allow the empty domain "." in dhcp domain-search (119) |

1062 | |
1063 | ||
1064 | version 2.54 | |
28866e95 SK |
1065 | There is no version 2.54 to avoid confusion with 2.53, |

c52e1897 SK |
1067 | |

8ef5ada2 SK |
1069 | version 2.53 |
1070 | Fix failure to compile on Debian/kFreeBSD. Thanks to | |
1071 | Axel Beckert and Petr Salinger. | |
1072 | ||
1073 | Fix code to avoid scary strict-aliasing warnings | |
1074 | generated by gcc 4.4. | |
1075 | ||
1076 | Added FAQ entry warning about DHCP failures with Vista | |
1077 | when firewalls block 255.255.255.255. | |
1078 | ||
1079 | Fixed bug which caused bad things to happen if a | |
1080 | resolv.conf file which exists is subsequently removed. | |
1081 | Thanks to Nikolai Saoukh for the patch. | |
1082 | ||
1083 | Rationalised the DHCP tag system. Every configuration item | |
1084 | which can set a tag does so by adding "set:<tag>" and | |
1085 | every configuration item which is conditional on a tag is | |
1086 | made so by "tag:<tag>". The NOT operator changes to '!', | |
1087 | which is a bit more intuitive too. Dhcp-host directives | |
1088 | can set more than one tag now. The old '#' NOT, | |
1089 | "net:" prefix and no-prefixes are still honoured, so | |
1090 | no existing config file needs to be changed, but | |
1091 | the documentation and new-style config files should be | |
1092 | much less confusing. | |
1093 | ||
1094 | Added --tag-if to allow boolean operations on tags. | |
1095 | This allows complicated logic to be clearer and more | |
1096 | general. A great suggestion from Richard Voigt. | |
1097 | ||
1098 | Add broadcast/unicast information to DHCP logging. | |
1099 | ||
1100 | Allow --dhcp-broadcast to be unconditional. | |
1101 | ||
1102 | Fixed incorrect behaviour with NOT <tag> conditionals in | |
1103 | dhcp-options. Thanks to Max Turkewitz for assistance | |
1104 | finding this. | |
1105 | ||
1106 | If we send vendor-class encapsulated options based on the | |
1107 | vendor-class supplied by the client, and no explicit | |
1108 | vendor-class option is given, echo back the vendor-class | |
1109 | from the client. | |
1110 | ||
1111 | Fix bug which stopped dnsmasq from matching both a | |
1112 | circuitid and a remoteid. Thanks to Ignacio Bravo for | |
1113 | finding this. | |
1114 | ||
1115 | Add --dhcp-proxy, which makes it possible to configure | |
1116 | dnsmasq to use a DHCP relay agent as a full proxy, with | |
1117 | all DHCP messages passing through the proxy. This is | |
1118 | useful if the relay adds extra information to the packets | |
1119 | it forwards, but cannot be configured with the RFC 5107 | |
1120 | server-override option. | |
1121 | ||
1122 | Added interface:<iface name> part to dhcp-range. The | |
1123 | semantics of this are very odd at first sight, but it | |
1124 | allows a single line of the form | |
1125 | dhcp-range=interface:virt0,192.168.0.4,192.168.0.200 | |
1126 | to be added to dnsmasq configuration which then supplies | |
1127 | DHCP and DNS services to that interface, without affecting | |
1128 | what services are supplied to other interfaces and | |
1129 | irrespective of the existance or lack of | |
1130 | interface=<interface> | |
1131 | lines elsewhere in the dnsmasq configuration. The idea is | |
1132 | that such a line can be added automatically by libvirt | |
1133 | or equivalent systems, without disturbing any manual | |
1134 | configuration. | |
1135 | ||
1136 | Similarly to the above, allow --enable-tftp=<interface> | |
1137 | ||
1138 | Allow a TFTP root to be set separately for requests via | |
1139 | different interfaces, --tftp-root=<path>,<interface> | |
1140 | ||
1141 | Correctly handle and log clashes between CNAMES and | |
1142 | DNS names being given to DHCP leases. This fixes a bug | |
1143 | which caused nonsense IP addresses to be logged. Thanks to | |
1144 | Sergei Zhirikov for finding and analysing the problem. | |
1145 | ||
1146 | Tweak flush_log so as to avoid leaving the log | |
1147 | file in non-blocking mode. O_NONBLOCK is a property of the | |
1148 | file, not the process/descriptor. | |
1149 | ||
1150 | Fix contrib/Solaris10/create_package | |
1151 | (/usr/man -> /usr/share/man) Thanks to Vita Batrla. | |
1152 | ||
1153 | Fix a problem where, if a client got a lease, then went | |
1154 | to another subnet and got another lease, then moved back, | |
1155 | it couldn't resume the old lease, but would instead get | |
1156 | a new address. Thanks to Leonardo Rodrigues for spotting | |
1157 | this and testing the fix. | |
1158 | ||
1159 | Fix weird bug which sometimes omitted certain characters | |
1160 | from the start of quoted strings in dhcp-options. Thanks | |
1161 | to Dayton Turner for spotting the problem. | |
1162 | ||
1163 | Add facility to redirect some domains to the standard | |
1164 | upstream servers: this allows something like | |
1165 | --server=/google.com/1.2.3.4 --server=/www.google.com/# | |
1166 | which will send queries for *.google.com to 1.2.3.4, | |
1167 | except *www.google.com which will be forwarded as usual. | |
1168 | Thanks to AJ Weber for prompting this addition. | |
1169 | ||
1170 | Improve the hash-algorithm used to generate IP addresses | |
1171 | from MAC addresses during initial DHCP address | |
1172 | allocation. This improves performance when large numbers | |
1173 | of hosts with similar MAC addresses all try and get an IP | |
1174 | address at the same time. Thanks to Paul Smith for his | |
1175 | work on this. | |
1176 | ||
1177 | Tweak DHCP code so that --bridge-interface can be used to | |
1178 | select which IP alias of an interface should be used for | |
1179 | DHCP purposes on Linux. If eth0 has an alias eth0:dhcp | |
1180 | then adding --bridge-interface=eth0:dhcp,eth0 will use | |
1181 | the address of eth0:dhcp to determine the correct subnet | |
1182 | for DHCP address allocation. Thanks to Pawel Golaszewski | |
1183 | for prompting this and Eric Cooper for further testing. | |
1184 | ||
1185 | Add --dhcp-generate-names. Suggestion by Ferenc Wagner. | |
1186 | ||
1187 | Tweak DNS server selection algorithm when there is more | |
1188 | than one server available for a domain, eg. | |
1189 | --server=/mydomain/1.1.1.1 | |
1190 | --server=/mydomain/2.2.2.2 | |
1191 | Thanks to Alberto Cuesta-Canada for spotting a weakness | |
1192 | here. | |
1193 | ||
1194 | Add --max-ttl. Thanks to Fredrik Ringertz for the patch. | |
1195 | ||
1196 | Allow --log-facility=- to force all logging to | |
1197 | stderr. Suggestion from Clemens Fischer. | |
1198 | ||
1199 | Fix regression which caused configuration like | |
1200 | --address=/.domain.com/1.2.3.4 to be rejected. The dot to the | |
1201 | left of the domain has been implied and not required for a | |
1202 | long time, but it should be accepted for backward | |
1203 | compatibility. Thanks to Andrew Burcin for spotting this. | |
1204 | ||
1205 | Add --rebind-domain-ok and --rebind-localhost-ok. | |
1206 | Suggestion from Clemens Fischer. | |
1207 | ||
1208 | Log replies to queries of type TXT, when --log-queries | |
1209 | is set. | |
1210 | ||
1211 | Fix compiler warnings when compiled with -DNO_DHCP. Thanks | |
1212 | to Shantanu Gadgil for the patch. | |
1213 | ||
1214 | Updated French translation. Thanks to Gildas Le Nadan. | |

1220 | Added contrib/static-arp, thanks to Darren Hoo. | |
1221 | ||
1222 | Fix corruption of the domain when a name from /etc/hosts | |
1223 | overrides one supplied by a DHCP client. Thanks to Fedor | |
1224 | Kozhevnikov for spotting the problem. | |
1225 | ||
1226 | Updated Spanish translation. Thanks to Chris Chatham. | |

316e2730 SK |
1229 | version 2.52 |
1230 | Work around a Linux kernel bug which insists that the | |
1231 | length of the option passed to setsockopt must be at least | |
1232 | sizeof(int) bytes, even if we're calling SO_BINDTODEVICE | |
1233 | and the device name is "lo". Note that this is fixed | |
1234 | in kernel 2.6.31, but the workaround is harmless and | |
1235 | allows earlier kernels to be used. Also fix dnsmasq | |
1236 | bug which reported the wrong address when this failed. | |
1237 | Thanks to Fedor for finding this. | |
1238 | ||
1239 | The API for IPv6 PKTINFO changed around Linux kernel | |
1240 | 2.6.14. Workaround the case where dnsmasq is compiled | |
1241 | against newer headers, but then run on an old kernel: | |
1242 | necessary for some *WRT distros. | |
1243 | ||
1244 | Re-read the set of network interfaces when re-loading | |
1245 | /etc/resolv.conf if --bind-interfaces is not set. This | |
1246 | handles the case that loopback interfaces do not exist | |
1247 | when dnsmasq is first started. | |
1248 | ||
1249 | Tweak the PXE code to support port 4011. This should | |
1250 | reduce broadcasts and make things more reliable when other | |
1251 | servers are around. It also improves inter-operability | |
1252 | with certain clients. | |
1253 | ||
1254 | Make a pxe-service configuration with no filename or boot | |
1255 | service type legal: this does a local boot. eg. | |
1256 | pxe-service=x86PC, "Local boot" | |
1257 | ||
1258 | Be more conservative in detecting "A for A" | |
1259 | queries. Dnsmasq checks if the name in a type=A query looks | |
1260 | like a dotted-quad IP address and answers the query itself | |
1261 | if so, rather than forwarding it. Previously dnsmasq | |
1262 | relied in the library function inet_addr() to convert | |
1263 | addresses, and that will accept some things which are | |
1264 | confusing in this context, like 1.2.3 or even just | |
1265 | 1234. Now we only do A for A processing for four decimal | |
1266 | numbers delimited by dots. | |
1267 | ||
1268 | A couple of tweaks to fix compilation on Solaris. Thanks | |
1269 | to Joel Macklow for help with this. | |
1270 | ||
1271 | Another Solaris compilation tweak, needed for Solaris | |
1272 | 2009.06. Thanks to Lee Essen for that. | |
1273 | ||
1274 | Added extract packaging stuff from Lee Essen to | |
1275 | contrib/Solaris10. | |
1276 | ||
1277 | Increased the default limit on number of leases to 1000 | |
1278 | (from 150). This is mainly a defence against DoS attacks, | |
1279 | and for the average "one for two class C networks" | |
1280 | installation, IP address exhaustion does that just as | |
1281 | well. Making the limit greater than the number of IP | |
1282 | addresses available in such an installation removes a | |
1283 | surprise which otherwise can catch people out. | |
1284 | ||
1285 | Removed extraneous trailing space in the value of the | |
1286 | DNSMASQ_TIME_REMAINING DNSMASQ_LEASE_LENGTH and | |
1287 | DNSMASQ_LEASE_EXPIRES environment variables. Thanks to | |
1288 | Gildas Le Nadan for spotting this. | |
1289 | ||
1290 | Provide the network-id tags for a DHCP transaction to | |
1291 | the lease-change script in the environment variable | |
1292 | DNSMASQ_TAGS. A good suggestion from Gildas Le Nadan. | |
1293 | ||
1294 | Add support for RFC3925 "Vendor-Identifying Vendor | |
1295 | Options". The syntax looks like this: | |
1296 | --dhcp-option=vi-encap:<enterprise number>, ......... | |
1297 | ||
1298 | Add support to --dhcp-match to allow matching against | |
1299 | RFC3925 "Vendor-Identifying Vendor Classes". The syntax | |
1300 | looks like this: | |
1301 | --dhcp-match=tag,vi-encap<enterprise number>, <value> | |
1302 | ||
1303 | Add some application specific code to assist in | |
1304 | implementing the Broadband forum TR069 CPE-WAN | |
1305 | specification. The details are in contrib/CPE-WAN/README | |
1306 | ||
1307 | Increase the default DNS packet size limit to 4096, as | |
1308 | recommended by RFC5625 section 4.4.3. This can be | |
1309 | reconfigured using --edns-packet-max if needed. Thanks to | |
1310 | Francis Dupont for pointing this out. | |
1311 | ||
8ef5ada2 | 1312 | Rewrite query-ids even for TSIG signed packets, since |
316e2730 SK |
1313 | this is allowed by RFC5625 section 4.5. |
1314 | ||
1315 | Use getopt_long by default on OS X. It has been supported | |
1316 | since version 10.3.0. Thanks to Arek Dreyer for spotting | |
1317 | this. | |
1318 | ||
1319 | Added up-to-date startup configuration for MacOSX/launchd | |
1320 | in contrib/MacOSX-launchd. Thanks to Arek Dreyer for | |
1321 | providing this. | |
1322 | ||
1323 | Fix link error when including Dbus but excluding DHCP. | |
1324 | Thanks to Oschtan for the bug report. | |
1325 | ||
1326 | Updated French translation. Thanks to Gildas Le Nadan. | |
1327 | ||
1328 | Updated Polish translation. Thanks to Jan Psota. | |
1329 | ||
1330 | Updated Spanish translation. Thanks to Chris Chatham. | |

8ef5ada2 SK |
1332 | Fixed confusion about domains, when looking up DHCP hosts |
1333 | in /etc/hosts. This could cause spurious "Ignoring | |
1334 | domain..." messages. Thanks to Fedor Kozhevnikov for | |
1335 | finding and analysing the problem. | |
316e2730 | 1336 | |
8ef5ada2 | 1337 | |
1f15b81d SK |
1338 | version 2.51 |
1339 | Add support for internationalised DNS. Non-ASCII characters | |
1340 | in domain names found in /etc/hosts, /etc/ethers and | |
1341 | /etc/dnsmasq.conf will be correctly handled by translation to | |
1342 | punycode, as specified in RFC3490. This function is only | |
1343 | available if dnsmasq is compiled with internationalisation | |
1344 | support, and adds a dependency on GNU libidn. Without i18n | |
1345 | support, dnsmasq continues to be compilable with just | |
1346 | standard tools. Thanks to Yves Dorfsman for the | |
1347 | suggestion. | |
1348 | ||
1349 | Add two more environment variables for lease-change scripts: | |
1350 | First, DNSMASQ_SUPPLIED_HOSTNAME; this is set to the hostname | |
1351 | supplied by a client, even if the actual hostname used is | |
1352 | over-ridden by dhcp-host or dhcp-ignore-names directives. | |
1353 | Also DNSMASQ_RELAY_ADDRESS which gives the address of | |
1354 | a DHCP relay, if used. | |
1355 | Suggestions from Michael Rack. | |
1356 | ||
1357 | Fix regression which broke echo of relay-agent | |
1358 | options. Thanks to Michael Rack for spotting this. | |
1359 | ||
1360 | Don't treat option 67 as being interchangeable with | |
1361 | dhcp-boot parameters if it's specified as | |
1362 | dhcp-option-force. | |
1363 | ||
1364 | Make the code to call scripts on lease-change compile-time | |
1365 | optional. It can be switched off by editing src/config.h | |
1366 | or building with "make COPTS=-DNO_SCRIPT". | |
1367 | ||
1368 | Make the TFTP server cope with filenames from Windows/DOS | |
1369 | which use '\' as pathname separator. Thanks to Ralf for | |
1370 | the patch. | |
1371 | ||
1372 | Updated Polish translation. Thanks to Jan Psota. | |
1373 | ||
1374 | Warn if an IP address is duplicated in /etc/ethers. Thanks | |
1375 | to Felix Schwarz for pointing this out. | |
1376 | ||
1377 | Teach --conf-dir to take an option list of file suffices | |
1378 | which will be ignored when scanning the directory. Useful | |
1379 | for backup files etc. Thanks to Helmut Hullen for the | |
1380 | suggestion. | |
1381 | ||
1382 | Add new DHCP option named tftpserver-address, which | |
1383 | corresponds to the third argument of dhcp-boot. This | |
1384 | allows the complete functionality of dhcp-boot to be | |
1385 | replicated with dhcp-option. Useful when using | |
1386 | dhcp-optsfile. | |
1387 | ||
1388 | Test which upstream nameserver to use every 10 seconds | |
1389 | or 50 queries and not just when a query times out and | |
1390 | is retried. This should improve performance when there | |
1391 | is a slow nameserver in the list. Thanks to Joe for the | |
1392 | suggestion. | |
1393 | ||
1394 | Don't do any PXE processing, even for clients with the | |
1395 | correct vendorclass, unless at least one pxe-prompt or | |
1396 | pxe-service option is given. This stops dnsmasq | |
1397 | interfering with proxy PXE subsystems when it is just | |
1398 | the DHCP server. Thanks to Spencer Clark for spotting this. | |
1399 | ||
1400 | Limit the blocksize used for TFTP transfers to a value | |
1401 | which avoids packet fragmentation, based on the MTU of the | |
1402 | local interface. Many netboot ROMs can't cope with | |
1403 | fragmented packets. | |
1404 | ||
1405 | Honour dhcp-ignore configuration for PXE and proxy-PXE | |
1406 | requests. Thanks to Niels Basjes for the bug report. | |
1407 | ||
1408 | Updated French translation. Thanks to Gildas Le Nadan. | |
1409 | ||
1410 | ||
77e94da7 | 1411 | version 2.50 |
1f15b81d | 1412 | Fix security problem which allowed any host permitted to |
77e94da7 SK |
1413 | do TFTP to possibly compromise dnsmasq by remote buffer |
1414 | overflow when TFTP enabled. Thanks to Core Security | |
1415 | Technologies and Iván Arce, Pablo Hernán Jorge, Alejandro | |
1416 | Pablo Rodriguez, Martín Coco, Alberto Soliño Testa and | |
1417 | Pablo Annetta. This problem has Bugtraq id: 36121 | |
1418 | and CVE: 2009-2957 | |
1419 | ||
1420 | Fix a problem which allowed a malicious TFTP client to | |
1421 | crash dnsmasq. Thanks to Steve Grubb at Red Hat for | |
1422 | spotting this. This problem has Bugtraq id: 36120 and | |
1423 | CVE: 2009-2958 | |
1424 | ||
1425 | ||
03a97b61 SK |
1426 | version 2.49 |
1427 | Fix regression in 2.48 which disables the lease-change | |
1428 | script. Thanks to Jose Luis Duran for spotting this. | |
1429 | ||
1430 | Log TFTP "file not found" errors. These were not logged, | |
1431 | since a normal PXELinux boot generates many of them, but | |
1432 | the lack of the messages seems to be more confusing than | |
1433 | routinely seeing them when there is no real error. | |
1434 | ||
1435 | Update Spanish translation. Thanks to Chris Chatham. | |
1436 | ||

7622fc06 SK |
1438 | version 2.48 |
1439 | Archived the extensive, backwards, changelog to | |

1441 | version 2.43 and runs conventionally. | |
9e4abcb5 | 1442 | |
7622fc06 SK |
1443 | Fixed bug which broke binding of servers to physical |
1444 | interfaces when interface names were longer than four | |
1445 | characters. Thanks to MURASE Katsunori for the patch. | |
9e4abcb5 | 1446 | |
7622fc06 SK |
1447 | Fixed netlink code to check that messages come from the |
1448 | correct source, and not another userspace process. Thanks | |
1449 | to Steve Grubb for the patch. | |
9e4abcb5 | 1450 | |
7622fc06 SK |
1451 | Maintainability drive: removed bug and missing feature |
1452 | workarounds for some old platforms. Solaris 9, OpenBSD | |
1453 | older than 4.1, Glibc older than 2.2, Linux 2.2.x and | |
1454 | DBus older than 1.1.x are no longer supported. | |
9e4abcb5 | 1455 | |
7622fc06 SK |
1456 | Don't read included configuration files more than once: |
1457 | allows complex configuration structures without problems. | |
9e4abcb5 | 1458 | |
7622fc06 SK |
1459 | Mark log messages from the various subsystems in dnsmasq: |
1460 | messages from the DHCP subsystem now have the ident string | |
1461 | "dnsmasq-dhcp" and messages from TFTP have ident | |
1462 | "dnsmasq-tftp". Thanks to Olaf Westrik for the patch. | |
9e4abcb5 | 1463 | |
7622fc06 SK |
1464 | Fix possible infinite DHCP protocol loop when an IP |
1465 | address nailed to a hostname (not a MAC address) and a | |
1466 | host sometimes provides the name, sometimes not. | |
9e4abcb5 | 1467 | |
7622fc06 SK |
1468 | Allow --addn-hosts to take a directory: all the files |
1469 | in the directory are read. Thanks to Phil Cornelius for | |
1470 | the suggestion. | |
9e4abcb5 | 1471 | |
7622fc06 | 1472 | Support --bridge-interface on all platforms, not just BSD. |
1ab84e2f | 1473 | |
7622fc06 SK |
1474 | Added support for advanced PXE functions. It's now |
1475 | possible to define a prompt and menu options which will | |
1476 | be displayed when a client PXE boots. It's also possible to | |
1477 | hand-off booting to other boot servers. Proxy-DHCP, where | |
1478 | dnsmasq just supplies the PXE information and another DHCP | |
1479 | server does address allocation, is also allowed. See the | |
1480 | --pxe-prompt and --pxe-service keywords. Thanks to | |
1481 | Alkis Georgopoulos for the suggestion and Guilherme Moro | |
1482 | and Michael Brown for assistance. | |
1483 | ||
1484 | Improvements to DHCP logging. Thanks to Tom Metro for | |
1485 | useful suggestions. | |
3be34541 | 1486 | |
7622fc06 SK |
1487 | Add ability to build dnsmasq without DHCP support. To do |
1488 | this, edit src/config.h or build with | |
1489 | "make COPTS=-DNO_DHCP". Thanks to Mahavir Jain for the patch. | |
36717eee | 1490 | |
7622fc06 SK |
1491 | Added --test command-line switch - syntax check |
1492 | configuration files only. | |

7622fc06 SK |
1500 | Fixed interface enumeration code to work on NetBSD |
1501 | 5.0. Thanks to Roy Marples for the patch. | |
3d8df260 | 1502 | |
7622fc06 SK |
1503 | Updated config.h to use the same location for the lease |
1504 | file on NetBSD as the other *BSD variants. Also allow | |
1505 | LEASEFILE and CONFFILE symbols to be overriden in CFLAGS. | |
3d8df260 | 1506 | |
7622fc06 SK |
1507 | Handle duplicate address detection on IPv6 more |
1508 | intelligently. In IPv6, an interface can have an address | |
1509 | which is not usable, because it is still undergoing DAD | |
1510 | (such addresses are marked "tentative"). Attempting to | |
1511 | bind to an address in this state returns an error, | |
1512 | EADDRNOTAVAIL. Previously, on getting such an error, | |
1513 | dnsmasq would silently abandon the address, and never | |
1514 | listen on it. Now, it retries once per second for 20 | |
1515 | seconds before generating a fatal error. 20 seconds should | |
1516 | be long enough for any DAD process to complete, but can be | |
1517 | adjusted in src/config.h if necessary. Thanks to Martin | |
1518 | Krafft for the bug report. | |
3d8df260 | 1519 | |
7622fc06 | 1520 | Add DBus introspection. Patch from Jeremy Laine. |

7622fc06 SK |
1526 | Support arbitrarily encapsulated DHCP options, suggestion |
1527 | and initial patch from Samium Gromoff. This is useful for | |
1528 | (eg) gPXE, which expect all its private options to be | |
1529 | encapsulated inside a single option 175. So, eg, | |
b8187c80 | 1530 | |
7622fc06 SK |
1531 | dhcp-option = encap:175, 190, "iscsi-client0" |
1532 | dhcp-option = encap:175, 191, "iscsi-client0-secret" | |
b8187c80 | 1533 | |
7622fc06 | 1534 | will provide iSCSI parameters to gPXE. |
b8187c80 | 1535 | |
7622fc06 SK |
1536 | Enhance --dhcp-match to allow testing of the contents of a |
1537 | client-sent option, as well as its presence. This | |
1538 | application in mind for this is RFC 4578 | |
1539 | client-architecture specifiers, but it's generally useful. | |
1540 | Joey Korkames suggested the enhancement. | |
b8187c80 | 1541 | |
7622fc06 SK |
1542 | Move from using the IP_XMIT_IF ioctl to IP_BOUND_IF on |
1543 | OpenSolaris. Thanks to Bastian Machek for the heads-up. | |
b8187c80 | 1544 | |
7622fc06 SK |
1545 | No longer complain about blank lines in |
1546 | /etc/ethers. Thanks to Jon Nelson for the patch. | |
b8187c80 | 1547 | |
7622fc06 SK |
1548 | Fix binding of servers to physical devices, eg |
1549 | --server=/domain/1.2.3.4@eth0 which was broken from 2.43 | |
1550 | onwards unless --query-port=0 set. Thanks to Peter Naulls | |

1553 | Reply to DHCPINFORM requests even when the supplied ciaddr |
1554 | doesn't fall in any dhcp-range. In this case it's not | |

1558 | Allow the source address of an alias to be a range: |
1559 | --alias=192.168.0.0,10.0.0.0,255.255.255.0 maps the whole | |
1560 | subnet 192.168.0.0->192.168.0.255 to 10.0.0.0->10.0.0.255, | |

1566 | Don't dynamically allocate DHCP addresses which may break |
1567 | Windows. Addresses which end in .255 or .0 are broken in | |
1568 | Windows even when using supernetting. | |
1569 | --dhcp-range=192.168.0.1,192.168.1.254,255,255,254.0 means | |
1570 | 192.168.0.255 is a valid IP address, but not for Windows. | |
1571 | See Microsoft KB281579. We therefore no longer allocate | |
1572 | these addresses to avoid hard-to-diagnose problems. | |

1576 | Delete the PID-file when dnsmasq shuts down. Note that by |
1577 | this time, dnsmasq is normally not running as root, so | |
1578 | this will fail if the PID-file is stored in a root-owned | |
1579 | directory; such failure is silently ignored. To take | |
1580 | advantage of this feature, the PID-file must be stored in a | |
1581 | directory owned and write-able by the user running | |
1582 | dnsmasq. | |

1590 | Remove ISC-leasefile reading code. This has been |
1591 | deprecated for a long time, and last time I removed it, it | |
1592 | ended up going back by request of one user. This time, | |
1593 | it's gone for good; otherwise it would need to be | |
1594 | re-worked to support multiple domains (see below). | |
5aabfc78 | 1595 | |
7622fc06 SK |
1596 | Support DHCP clients in multiple DNS domains. This is a |
1597 | long-standing request. Clients are assigned to a domain | |
1598 | based in their IP address. | |
5aabfc78 | 1599 | |
7622fc06 SK |
1600 | Add --dhcp-fqdn flag, which changes behaviour if DNS names |
1601 | assigned to DHCP clients. When this is set, there must be | |
1602 | a domain associated with each client, and only | |
1603 | fully-qualified domain names are added to the DNS. The | |
1604 | advantage is that the only the FQDN needs to be unique, | |
1605 | so that two or more DHCP clients can share a hostname, as | |
1606 | long as they are in different domains. | |
5aabfc78 | 1607 | |
7622fc06 SK |

1634 | Allow for more that one MAC address in a dhcp-host |
1635 | line. This configuration tells dnsmasq that it's OK to | |
1636 | abandon a DHCP lease of the fixed address to one MAC | |
1637 | address, if another MAC address in the dhcp-host statement | |
1638 | asks for an address. This is useful to give a fixed | |
1639 | address to a host which has two network interfaces | |
1640 | (say, a laptop with wired and wireless interfaces.) | |
1641 | It's very important to ensure that only one interface | |
1642 | at a time is up, since dnsmasq abandons the first lease | |
1643 | and re-uses the address before the leased time has | |
1644 | elapsed. John Gray suggested this. | |

1646 | Tweak the response to a DHCP request packet with a wrong |
1647 | server-id when --dhcp-authoritative is set; dnsmasq now | |
1648 | returns a DHCPNAK, rather than silently ignoring the | |
1649 | packet. Thanks to Chris Marget for spotting this | |
1650 | improvement. | |

7622fc06 SK |
1652 | Add --cname option. This provides a limited alias |
1653 | function, usable for DHCP names. Thanks to AJ Weber for | |
1654 | suggestions on this. | |

7622fc06 SK |
1661 | Correct the text names for DHCP options 64 and 65 to be |
1662 | "nis+-domain" and "nis+-servers". | |

1666 | Force re-reading of /etc/resolv.conf when an "interface |
1667 | up" event occurs. | |

1670 | version 2.45 |
1671 | Fix total DNS failure in release 2.44 unless --min-port | |
1672 | specified. Thanks to Steven Barth and Grant Coady for | |
1673 | bugreport. Also reject out-of-range port spec, which could | |
1674 | break things too: suggestion from Gilles Espinasse. | |

1677 | version 2.44 |
1678 | Fix crash when unknown client attempts to renew a DHCP | |
1679 | lease, problem introduced in version 2.43. Thanks to | |
1680 | Carlos Carvalho for help chasing this down. | |
9e038946 | 1681 | |
7622fc06 SK |
1682 | Fix potential crash when a host which doesn't have a lease |
1683 | does DHCPINFORM. Again introduced in 2.43. This bug has | |
1684 | never been reported in the wild. | |
9e038946 | 1685 | |
7622fc06 SK |
1686 | Fix crash in netlink code introduced in 2.43. Thanks to |
1687 | Jean Wolter for finding this. | |
9e038946 | 1688 | |
7622fc06 SK |
1689 | Change implementation of min_port to work even if min-port |
1690 | is large. | |
9e038946 | 1691 | |
7622fc06 SK |
1692 | Patch to enable compilation of latest Mac OS X. Thanks to |
1693 | David Gilman. | |

1698 | version 2.43 | |
1699 | Updated Polish translation. Thanks to Jan Psota. | |
1700 | ||
1701 | Flag errors when configuration options are repeated | |
1702 | illegally. | |
1703 | ||
1704 | Further tweaks for GNU/kFreeBSD | |
1705 | ||
1706 | Add --no-wrap to msgmerge call - provides nicer .po file | |
1707 | format. | |
1708 | ||
1709 | Honour lease-time spec in dhcp-host lines even for | |
1710 | BOOTP. The user is assumed to known what they are doing in | |
1711 | this case. (Hosts without the time spec still get infinite | |
1712 | leases for BOOTP, over-riding the default in the | |
1713 | dhcp-range.) Thanks to Peter Katzmann for uncovering this. | |
1714 | ||
1715 | Fix problem matching relay-agent ids. Thanks to Michael | |
1716 | Rack for the bug report. | |
1717 | ||
1718 | Add --naptr-record option. Suggestion from Johan | |
1719 | Bergquist. | |
1720 | ||
1721 | Implement RFC 5107 server-id-override DHCP relay agent | |
1722 | option. | |
1723 | ||
1724 | Apply patches from Stefan Kruger for compilation on | |
1725 | Solaris 10 under Sun studio. | |
1726 | ||
1727 | Yet more tweaking of Linux capability code, to suppress | |
1728 | pointless wingeing from kernel 2.6.25 and above. | |
1729 | ||
1730 | Improve error checking during startup. Previously, some | |
1731 | errors which occurred during startup would be worked | |
1732 | around, with dnsmasq still starting up. Some were logged, | |
1733 | some silent. Now, they all cause a fatal error and dnsmasq | |
1734 | terminates with a non-zero exit code. The errors are those | |
1735 | associated with changing uid and gid, setting process | |
1736 | capabilities and writing the pidfile. Thanks to Uwe | |
1737 | Gansert and the Suse security team for pointing out | |
1738 | this improvement, and Bill Reimers for good implementation | |
1739 | suggestions. | |
1740 | ||
1741 | Provide NO_LARGEFILE compile option to switch off largefile | |
1742 | support when compiling against versions of uclibc which | |
1743 | don't support it. Thanks to Stephane Billiart for the patch. | |
1744 | ||
1745 | Implement random source ports for interactions with | |
1746 | upstream nameservers. New spoofing attacks have been found | |
1747 | against nameservers which do not do this, though it is not | |
1748 | clear if dnsmasq is vulnerable, since to doesn't implement | |
1749 | recursion. By default dnsmasq will now use a different | |
1750 | source port (and socket) for each query it sends | |
1751 | upstream. This behaviour can suppressed using the | |
1752 | --query-port option, and the old default behaviour | |
1753 | restored using --query-port=0. Explicit source-port | |
1754 | specifications in --server configs are still honoured. | |
1755 | ||
1756 | Replace the random number generator, for better | |
1757 | security. On most BSD systems, dnsmasq uses the | |
1758 | arc4random() RNG, which is secure, but on other platforms, | |
1759 | it relied on the C-library RNG, which may be | |
1760 | guessable and therefore allow spoofing. This release | |
1761 | replaces the libc RNG with the SURF RNG, from Daniel | |
1762 | J. Berstein's DJBDNS package. | |
1763 | ||
1764 | Don't attempt to change user or group or set capabilities | |
1765 | if dnsmasq is run as a non-root user. Without this, the | |
1766 | change from soft to hard errors when these fail causes | |
1767 | problems for non-root daemons listening on high | |
1768 | ports. Thanks to Patrick McLean for spotting this. | |
1769 | ||
1770 | Updated French translation. Thanks to Gildas Le Nadan. | |
