San Mehat | ffd6872 | 2010-01-20 09:56:15 -0800 | [diff] [blame] | 1 | version 2.51 |
| 2 | Add support for internationalised DNS. Non-ASCII characters |
| 3 | in domain names found in /etc/hosts, /etc/ethers and |
| 4 | /etc/dnsmasq.conf will be correctly handled by translation to |
| 5 | punycode, as specified in RFC3490. This function is only |
| 6 | available if dnsmasq is compiled with internationalisation |
| 7 | support, and adds a dependency on GNU libidn. Without i18n |
| 8 | support, dnsmasq continues to be compilable with just |
| 9 | standard tools. Thanks to Yves Dorfsman for the |
| 10 | suggestion. |
| 11 | |
| 12 | Add two more environment variables for lease-change scripts: |
| 13 | First, DNSMASQ_SUPPLIED_HOSTNAME; this is set to the hostname |
| 14 | supplied by a client, even if the actual hostname used is |
| 15 | over-ridden by dhcp-host or dhcp-ignore-names directives. |
| 16 | Also DNSMASQ_RELAY_ADDRESS which gives the address of |
| 17 | a DHCP relay, if used. |
| 18 | Suggestions from Michael Rack. |
| 19 | |
| 20 | Fix regression which broke echo of relay-agent |
| 21 | options. Thanks to Michael Rack for spotting this. |
| 22 | |
| 23 | Don't treat option 67 as being interchangeable with |
| 24 | dhcp-boot parameters if it's specified as |
| 25 | dhcp-option-force. |
| 26 | |
| 27 | Make the code to call scripts on lease-change compile-time |
| 28 | optional. It can be switched off by editing src/config.h |
| 29 | or building with "make COPTS=-DNO_SCRIPT". |
| 30 | |
| 31 | Make the TFTP server cope with filenames from Windows/DOS |
| 32 | which use '\' as pathname separator. Thanks to Ralf for |
| 33 | the patch. |
| 34 | |
| 35 | Updated Polish translation. Thanks to Jan Psota. |
| 36 | |
| 37 | Warn if an IP address is duplicated in /etc/ethers. Thanks |
| 38 | to Felix Schwarz for pointing this out. |
| 39 | |
| 40 | Teach --conf-dir to take an option list of file suffices |
| 41 | which will be ignored when scanning the directory. Useful |
| 42 | for backup files etc. Thanks to Helmut Hullen for the |
| 43 | suggestion. |
| 44 | |
| 45 | Add new DHCP option named tftpserver-address, which |
| 46 | corresponds to the third argument of dhcp-boot. This |
| 47 | allows the complete functionality of dhcp-boot to be |
| 48 | replicated with dhcp-option. Useful when using |
| 49 | dhcp-optsfile. |
| 50 | |
| 51 | Test which upstream nameserver to use every 10 seconds |
| 52 | or 50 queries and not just when a query times out and |
| 53 | is retried. This should improve performance when there |
| 54 | is a slow nameserver in the list. Thanks to Joe for the |
| 55 | suggestion. |
| 56 | |
| 57 | Don't do any PXE processing, even for clients with the |
| 58 | correct vendorclass, unless at least one pxe-prompt or |
| 59 | pxe-service option is given. This stops dnsmasq |
| 60 | interfering with proxy PXE subsystems when it is just |
| 61 | the DHCP server. Thanks to Spencer Clark for spotting this. |
| 62 | |
| 63 | Limit the blocksize used for TFTP transfers to a value |
| 64 | which avoids packet fragmentation, based on the MTU of the |
| 65 | local interface. Many netboot ROMs can't cope with |
| 66 | fragmented packets. |
| 67 | |
| 68 | Honour dhcp-ignore configuration for PXE and proxy-PXE |
| 69 | requests. Thanks to Niels Basjes for the bug report. |
| 70 | |
| 71 | Updated French translation. Thanks to Gildas Le Nadan. |
| 72 | |
| 73 | |
| 74 | version 2.50 |
| 75 | Fix security problem which allowed any host permitted to |
| 76 | do TFTP to possibly compromise dnsmasq by remote buffer |
| 77 | overflow when TFTP enabled. Thanks to Core Security |
| 78 | Technologies and Iván Arce, Pablo Hernán Jorge, Alejandro |
| 79 | Pablo Rodriguez, Martín Coco, Alberto Soliño Testa and |
| 80 | Pablo Annetta. This problem has Bugtraq id: 36121 |
| 81 | and CVE: 2009-2957 |
| 82 | |
| 83 | Fix a problem which allowed a malicious TFTP client to |
| 84 | crash dnsmasq. Thanks to Steve Grubb at Red Hat for |
| 85 | spotting this. This problem has Bugtraq id: 36120 and |
| 86 | CVE: 2009-2958 |
| 87 | |
| 88 | |
| 89 | version 2.49 |
| 90 | Fix regression in 2.48 which disables the lease-change |
| 91 | script. Thanks to Jose Luis Duran for spotting this. |
| 92 | |
| 93 | Log TFTP "file not found" errors. These were not logged, |
| 94 | since a normal PXELinux boot generates many of them, but |
| 95 | the lack of the messages seems to be more confusing than |
| 96 | routinely seeing them when there is no real error. |
| 97 | |
| 98 | Update Spanish translation. Thanks to Chris Chatham. |
| 99 | |
| 100 | |
| 101 | version 2.48 |
| 102 | Archived the extensive, backwards, changelog to |
| 103 | CHANGELOG.archive. The current changelog now runs from |
| 104 | version 2.43 and runs conventionally. |
| 105 | |
| 106 | Fixed bug which broke binding of servers to physical |
| 107 | interfaces when interface names were longer than four |
| 108 | characters. Thanks to MURASE Katsunori for the patch. |
| 109 | |
| 110 | Fixed netlink code to check that messages come from the |
| 111 | correct source, and not another userspace process. Thanks |
| 112 | to Steve Grubb for the patch. |
| 113 | |
| 114 | Maintainability drive: removed bug and missing feature |
| 115 | workarounds for some old platforms. Solaris 9, OpenBSD |
| 116 | older than 4.1, Glibc older than 2.2, Linux 2.2.x and |
| 117 | DBus older than 1.1.x are no longer supported. |
| 118 | |
| 119 | Don't read included configuration files more than once: |
| 120 | allows complex configuration structures without problems. |
| 121 | |
| 122 | Mark log messages from the various subsystems in dnsmasq: |
| 123 | messages from the DHCP subsystem now have the ident string |
| 124 | "dnsmasq-dhcp" and messages from TFTP have ident |
| 125 | "dnsmasq-tftp". Thanks to Olaf Westrik for the patch. |
| 126 | |
| 127 | Fix possible infinite DHCP protocol loop when an IP |
| 128 | address nailed to a hostname (not a MAC address) and a |
| 129 | host sometimes provides the name, sometimes not. |
| 130 | |
| 131 | Allow --addn-hosts to take a directory: all the files |
| 132 | in the directory are read. Thanks to Phil Cornelius for |
| 133 | the suggestion. |
| 134 | |
| 135 | Support --bridge-interface on all platforms, not just BSD. |
| 136 | |
| 137 | Added support for advanced PXE functions. It's now |
| 138 | possible to define a prompt and menu options which will |
| 139 | be displayed when a client PXE boots. It's also possible to |
| 140 | hand-off booting to other boot servers. Proxy-DHCP, where |
| 141 | dnsmasq just supplies the PXE information and another DHCP |
| 142 | server does address allocation, is also allowed. See the |
| 143 | --pxe-prompt and --pxe-service keywords. Thanks to |
| 144 | Alkis Georgopoulos for the suggestion and Guilherme Moro |
| 145 | and Michael Brown for assistance. |
| 146 | |
| 147 | Improvements to DHCP logging. Thanks to Tom Metro for |
| 148 | useful suggestions. |
| 149 | |
| 150 | Add ability to build dnsmasq without DHCP support. To do |
| 151 | this, edit src/config.h or build with |
| 152 | "make COPTS=-DNO_DHCP". Thanks to Mahavir Jain for the patch. |
| 153 | |
| 154 | Added --test command-line switch - syntax check |
| 155 | configuration files only. |
| 156 | |
| 157 | Updated French translation. Thanks to Gildas Le Nadan. |
| 158 | |
| 159 | |
| 160 | version 2.47 |
| 161 | Updated French translation. Thanks to Gildas Le Nadan. |
| 162 | |
| 163 | Fixed interface enumeration code to work on NetBSD |
| 164 | 5.0. Thanks to Roy Marples for the patch. |
| 165 | |
| 166 | Updated config.h to use the same location for the lease |
| 167 | file on NetBSD as the other *BSD variants. Also allow |
| 168 | LEASEFILE and CONFFILE symbols to be overriden in CFLAGS. |
| 169 | |
| 170 | Handle duplicate address detection on IPv6 more |
| 171 | intelligently. In IPv6, an interface can have an address |
| 172 | which is not usable, because it is still undergoing DAD |
| 173 | (such addresses are marked "tentative"). Attempting to |
| 174 | bind to an address in this state returns an error, |
| 175 | EADDRNOTAVAIL. Previously, on getting such an error, |
| 176 | dnsmasq would silently abandon the address, and never |
| 177 | listen on it. Now, it retries once per second for 20 |
| 178 | seconds before generating a fatal error. 20 seconds should |
| 179 | be long enough for any DAD process to complete, but can be |
| 180 | adjusted in src/config.h if necessary. Thanks to Martin |
| 181 | Krafft for the bug report. |
| 182 | |
| 183 | Add DBus introspection. Patch from Jeremy Laine. |
| 184 | |
| 185 | Update Dbus configuration file. Patch from Colin Walters. |
| 186 | Fix for this bug: |
| 187 | http://bugs.freedesktop.org/show_bug.cgi?id=18961 |
| 188 | |
| 189 | Support arbitrarily encapsulated DHCP options, suggestion |
| 190 | and initial patch from Samium Gromoff. This is useful for |
| 191 | (eg) gPXE, which expect all its private options to be |
| 192 | encapsulated inside a single option 175. So, eg, |
| 193 | |
| 194 | dhcp-option = encap:175, 190, "iscsi-client0" |
| 195 | dhcp-option = encap:175, 191, "iscsi-client0-secret" |
| 196 | |
| 197 | will provide iSCSI parameters to gPXE. |
| 198 | |
| 199 | Enhance --dhcp-match to allow testing of the contents of a |
| 200 | client-sent option, as well as its presence. This |
| 201 | application in mind for this is RFC 4578 |
| 202 | client-architecture specifiers, but it's generally useful. |
| 203 | Joey Korkames suggested the enhancement. |
| 204 | |
| 205 | Move from using the IP_XMIT_IF ioctl to IP_BOUND_IF on |
| 206 | OpenSolaris. Thanks to Bastian Machek for the heads-up. |
| 207 | |
| 208 | No longer complain about blank lines in |
| 209 | /etc/ethers. Thanks to Jon Nelson for the patch. |
| 210 | |
| 211 | Fix binding of servers to physical devices, eg |
| 212 | --server=/domain/1.2.3.4@eth0 which was broken from 2.43 |
| 213 | onwards unless --query-port=0 set. Thanks to Peter Naulls |
| 214 | for the bug report. |
| 215 | |
| 216 | Reply to DHCPINFORM requests even when the supplied ciaddr |
| 217 | doesn't fall in any dhcp-range. In this case it's not |
| 218 | possible to supply a complete configuration, but |
| 219 | individually-configured options (eg PAC) may be useful. |
| 220 | |
| 221 | Allow the source address of an alias to be a range: |
| 222 | --alias=192.168.0.0,10.0.0.0,255.255.255.0 maps the whole |
| 223 | subnet 192.168.0.0->192.168.0.255 to 10.0.0.0->10.0.0.255, |
| 224 | as before. |
| 225 | --alias=192.168.0.10-192.168.0.40,10.0.0.0,255.255.255.0 |
| 226 | maps only the 192.168.0.10->192.168.0.40 region. Thanks to |
| 227 | Ib Uhrskov for the suggestion. |
| 228 | |
| 229 | Don't dynamically allocate DHCP addresses which may break |
| 230 | Windows. Addresses which end in .255 or .0 are broken in |
| 231 | Windows even when using supernetting. |
| 232 | --dhcp-range=192.168.0.1,192.168.1.254,255,255,254.0 means |
| 233 | 192.168.0.255 is a valid IP address, but not for Windows. |
| 234 | See Microsoft KB281579. We therefore no longer allocate |
| 235 | these addresses to avoid hard-to-diagnose problems. |
| 236 | |
| 237 | Update Polish translation. Thanks to Jan Psota. |
| 238 | |
| 239 | Delete the PID-file when dnsmasq shuts down. Note that by |
| 240 | this time, dnsmasq is normally not running as root, so |
| 241 | this will fail if the PID-file is stored in a root-owned |
| 242 | directory; such failure is silently ignored. To take |
| 243 | advantage of this feature, the PID-file must be stored in a |
| 244 | directory owned and write-able by the user running |
| 245 | dnsmasq. |
| 246 | |
| 247 | |
| 248 | version 2.46 |
| 249 | Allow --bootp-dynamic to take a netid tag, so that it may |
| 250 | be selectively enabled. Thanks to Olaf Westrik for the |
| 251 | suggestion. |
| 252 | |
| 253 | Remove ISC-leasefile reading code. This has been |
| 254 | deprecated for a long time, and last time I removed it, it |
| 255 | ended up going back by request of one user. This time, |
| 256 | it's gone for good; otherwise it would need to be |
| 257 | re-worked to support multiple domains (see below). |
| 258 | |
| 259 | Support DHCP clients in multiple DNS domains. This is a |
| 260 | long-standing request. Clients are assigned to a domain |
| 261 | based in their IP address. |
| 262 | |
| 263 | Add --dhcp-fqdn flag, which changes behaviour if DNS names |
| 264 | assigned to DHCP clients. When this is set, there must be |
| 265 | a domain associated with each client, and only |
| 266 | fully-qualified domain names are added to the DNS. The |
| 267 | advantage is that the only the FQDN needs to be unique, |
| 268 | so that two or more DHCP clients can share a hostname, as |
| 269 | long as they are in different domains. |
| 270 | |
| 271 | Set environment variable DNSMASQ_DOMAIN when invoking |
| 272 | lease-change script. This may be useful information to |
| 273 | have now that it's variable. |
| 274 | |
| 275 | Tighten up data-checking code for DNS packet |
| 276 | handling. Thanks to Steve Dodd who found certain illegal |
| 277 | packets which could crash dnsmasq. No memory overwrite was |
| 278 | possible, so this is not a security issue beyond the DoS |
| 279 | potential. |
| 280 | |
| 281 | Update example config dhcp option 47, the previous |
| 282 | suggestion generated an illegal, zero-length, |
| 283 | option. Thanks to Matthias Andree for finding this. |
| 284 | |
| 285 | Rewrite hosts-file reading code to remove the limit of |
| 286 | 1024 characters per line. John C Meuser found this. |
| 287 | |
| 288 | Create a net-id tag with the name of the interface on |
| 289 | which the DHCP request was received. |
| 290 | |
| 291 | Fixed minor memory leak in DBus code, thanks to Jeremy |
| 292 | Laine for the patch. |
| 293 | |
| 294 | Emit DBus signals as the DHCP lease database |
| 295 | changes. Thanks to Jeremy Laine for the patch. |
| 296 | |
| 297 | Allow for more that one MAC address in a dhcp-host |
| 298 | line. This configuration tells dnsmasq that it's OK to |
| 299 | abandon a DHCP lease of the fixed address to one MAC |
| 300 | address, if another MAC address in the dhcp-host statement |
| 301 | asks for an address. This is useful to give a fixed |
| 302 | address to a host which has two network interfaces |
| 303 | (say, a laptop with wired and wireless interfaces.) |
| 304 | It's very important to ensure that only one interface |
| 305 | at a time is up, since dnsmasq abandons the first lease |
| 306 | and re-uses the address before the leased time has |
| 307 | elapsed. John Gray suggested this. |
| 308 | |
| 309 | Tweak the response to a DHCP request packet with a wrong |
| 310 | server-id when --dhcp-authoritative is set; dnsmasq now |
| 311 | returns a DHCPNAK, rather than silently ignoring the |
| 312 | packet. Thanks to Chris Marget for spotting this |
| 313 | improvement. |
| 314 | |
| 315 | Add --cname option. This provides a limited alias |
| 316 | function, usable for DHCP names. Thanks to AJ Weber for |
| 317 | suggestions on this. |
| 318 | |
| 319 | Updated contrib/webmin with latest version from Neil |
| 320 | Fisher. |
| 321 | |
| 322 | Updated Polish translation. Thanks to Jan Psota. |
| 323 | |
| 324 | Correct the text names for DHCP options 64 and 65 to be |
| 325 | "nis+-domain" and "nis+-servers". |
| 326 | |
| 327 | Updated Spanish translation. Thanks to Chris Chatham. |
| 328 | |
| 329 | Force re-reading of /etc/resolv.conf when an "interface |
| 330 | up" event occurs. |
| 331 | |
| 332 | |
| 333 | version 2.45 |
| 334 | Fix total DNS failure in release 2.44 unless --min-port |
| 335 | specified. Thanks to Steven Barth and Grant Coady for |
| 336 | bugreport. Also reject out-of-range port spec, which could |
| 337 | break things too: suggestion from Gilles Espinasse. |
| 338 | |
| 339 | |
| 340 | version 2.44 |
| 341 | Fix crash when unknown client attempts to renew a DHCP |
| 342 | lease, problem introduced in version 2.43. Thanks to |
| 343 | Carlos Carvalho for help chasing this down. |
| 344 | |
| 345 | Fix potential crash when a host which doesn't have a lease |
| 346 | does DHCPINFORM. Again introduced in 2.43. This bug has |
| 347 | never been reported in the wild. |
| 348 | |
| 349 | Fix crash in netlink code introduced in 2.43. Thanks to |
| 350 | Jean Wolter for finding this. |
| 351 | |
| 352 | Change implementation of min_port to work even if min-port |
| 353 | is large. |
| 354 | |
| 355 | Patch to enable compilation of latest Mac OS X. Thanks to |
| 356 | David Gilman. |
| 357 | |
| 358 | Update Spanish translation. Thanks to Christopher Chatham. |
| 359 | |
| 360 | |
| 361 | version 2.43 |
| 362 | Updated Polish translation. Thanks to Jan Psota. |
| 363 | |
| 364 | Flag errors when configuration options are repeated |
| 365 | illegally. |
| 366 | |
| 367 | Further tweaks for GNU/kFreeBSD |
| 368 | |
| 369 | Add --no-wrap to msgmerge call - provides nicer .po file |
| 370 | format. |
| 371 | |
| 372 | Honour lease-time spec in dhcp-host lines even for |
| 373 | BOOTP. The user is assumed to known what they are doing in |
| 374 | this case. (Hosts without the time spec still get infinite |
| 375 | leases for BOOTP, over-riding the default in the |
| 376 | dhcp-range.) Thanks to Peter Katzmann for uncovering this. |
| 377 | |
| 378 | Fix problem matching relay-agent ids. Thanks to Michael |
| 379 | Rack for the bug report. |
| 380 | |
| 381 | Add --naptr-record option. Suggestion from Johan |
| 382 | Bergquist. |
| 383 | |
| 384 | Implement RFC 5107 server-id-override DHCP relay agent |
| 385 | option. |
| 386 | |
| 387 | Apply patches from Stefan Kruger for compilation on |
| 388 | Solaris 10 under Sun studio. |
| 389 | |
| 390 | Yet more tweaking of Linux capability code, to suppress |
| 391 | pointless wingeing from kernel 2.6.25 and above. |
| 392 | |
| 393 | Improve error checking during startup. Previously, some |
| 394 | errors which occurred during startup would be worked |
| 395 | around, with dnsmasq still starting up. Some were logged, |
| 396 | some silent. Now, they all cause a fatal error and dnsmasq |
| 397 | terminates with a non-zero exit code. The errors are those |
| 398 | associated with changing uid and gid, setting process |
| 399 | capabilities and writing the pidfile. Thanks to Uwe |
| 400 | Gansert and the Suse security team for pointing out |
| 401 | this improvement, and Bill Reimers for good implementation |
| 402 | suggestions. |
| 403 | |
| 404 | Provide NO_LARGEFILE compile option to switch off largefile |
| 405 | support when compiling against versions of uclibc which |
| 406 | don't support it. Thanks to Stephane Billiart for the patch. |
| 407 | |
| 408 | Implement random source ports for interactions with |
| 409 | upstream nameservers. New spoofing attacks have been found |
| 410 | against nameservers which do not do this, though it is not |
| 411 | clear if dnsmasq is vulnerable, since to doesn't implement |
| 412 | recursion. By default dnsmasq will now use a different |
| 413 | source port (and socket) for each query it sends |
| 414 | upstream. This behaviour can suppressed using the |
| 415 | --query-port option, and the old default behaviour |
| 416 | restored using --query-port=0. Explicit source-port |
| 417 | specifications in --server configs are still honoured. |
| 418 | |
| 419 | Replace the random number generator, for better |
| 420 | security. On most BSD systems, dnsmasq uses the |
| 421 | arc4random() RNG, which is secure, but on other platforms, |
| 422 | it relied on the C-library RNG, which may be |
| 423 | guessable and therefore allow spoofing. This release |
| 424 | replaces the libc RNG with the SURF RNG, from Daniel |
| 425 | J. Berstein's DJBDNS package. |
| 426 | |
| 427 | Don't attempt to change user or group or set capabilities |
| 428 | if dnsmasq is run as a non-root user. Without this, the |
| 429 | change from soft to hard errors when these fail causes |
| 430 | problems for non-root daemons listening on high |
| 431 | ports. Thanks to Patrick McLean for spotting this. |
| 432 | |
| 433 | Updated French translation. Thanks to Gildas Le Nadan. |
| 434 | |
| 435 | |
| 436 | version 2.42 |
| 437 | The changelog for version 2.42 and earlier is |
| 438 | available in CHANGELOG.archive. |
