| version 2.51 |
| Add support for internationalised DNS. Non-ASCII characters |
| in domain names found in /etc/hosts, /etc/ethers and |
| /etc/dnsmasq.conf will be correctly handled by translation to |
| punycode, as specified in RFC3490. This function is only |
| available if dnsmasq is compiled with internationalisation |
| support, and adds a dependency on GNU libidn. Without i18n |
| support, dnsmasq continues to be compilable with just |
| standard tools. Thanks to Yves Dorfsman for the |
| suggestion. |
| |
| Add two more environment variables for lease-change scripts: |
| First, DNSMASQ_SUPPLIED_HOSTNAME; this is set to the hostname |
| supplied by a client, even if the actual hostname used is |
| over-ridden by dhcp-host or dhcp-ignore-names directives. |
| Also DNSMASQ_RELAY_ADDRESS which gives the address of |
| a DHCP relay, if used. |
| Suggestions from Michael Rack. |
| |
| Fix regression which broke echo of relay-agent |
| options. Thanks to Michael Rack for spotting this. |
| |
| Don't treat option 67 as being interchangeable with |
| dhcp-boot parameters if it's specified as |
| dhcp-option-force. |
| |
| Make the code to call scripts on lease-change compile-time |
| optional. It can be switched off by editing src/config.h |
| or building with "make COPTS=-DNO_SCRIPT". |
| |
| Make the TFTP server cope with filenames from Windows/DOS |
| which use '\' as pathname separator. Thanks to Ralf for |
| the patch. |
| |
| Updated Polish translation. Thanks to Jan Psota. |
| |
| Warn if an IP address is duplicated in /etc/ethers. Thanks |
| to Felix Schwarz for pointing this out. |
| |
| Teach --conf-dir to take an option list of file suffices |
| which will be ignored when scanning the directory. Useful |
| for backup files etc. Thanks to Helmut Hullen for the |
| suggestion. |
| |
| Add new DHCP option named tftpserver-address, which |
| corresponds to the third argument of dhcp-boot. This |
| allows the complete functionality of dhcp-boot to be |
| replicated with dhcp-option. Useful when using |
| dhcp-optsfile. |
| |
| Test which upstream nameserver to use every 10 seconds |
| or 50 queries and not just when a query times out and |
| is retried. This should improve performance when there |
| is a slow nameserver in the list. Thanks to Joe for the |
| suggestion. |
| |
| Don't do any PXE processing, even for clients with the |
| correct vendorclass, unless at least one pxe-prompt or |
| pxe-service option is given. This stops dnsmasq |
| interfering with proxy PXE subsystems when it is just |
| the DHCP server. Thanks to Spencer Clark for spotting this. |
| |
| Limit the blocksize used for TFTP transfers to a value |
| which avoids packet fragmentation, based on the MTU of the |
| local interface. Many netboot ROMs can't cope with |
| fragmented packets. |
| |
| Honour dhcp-ignore configuration for PXE and proxy-PXE |
| requests. Thanks to Niels Basjes for the bug report. |
| |
| Updated French translation. Thanks to Gildas Le Nadan. |
| |
| |
| version 2.50 |
| Fix security problem which allowed any host permitted to |
| do TFTP to possibly compromise dnsmasq by remote buffer |
| overflow when TFTP enabled. Thanks to Core Security |
| Technologies and Iván Arce, Pablo Hernán Jorge, Alejandro |
| Pablo Rodriguez, Martín Coco, Alberto Soliño Testa and |
| Pablo Annetta. This problem has Bugtraq id: 36121 |
| and CVE: 2009-2957 |
| |
| Fix a problem which allowed a malicious TFTP client to |
| crash dnsmasq. Thanks to Steve Grubb at Red Hat for |
| spotting this. This problem has Bugtraq id: 36120 and |
| CVE: 2009-2958 |
| |
| |
| version 2.49 |
| Fix regression in 2.48 which disables the lease-change |
| script. Thanks to Jose Luis Duran for spotting this. |
| |
| Log TFTP "file not found" errors. These were not logged, |
| since a normal PXELinux boot generates many of them, but |
| the lack of the messages seems to be more confusing than |
| routinely seeing them when there is no real error. |
| |
| Update Spanish translation. Thanks to Chris Chatham. |
| |
| |
| version 2.48 |
| Archived the extensive, backwards, changelog to |
| CHANGELOG.archive. The current changelog now runs from |
| version 2.43 and runs conventionally. |
| |
| Fixed bug which broke binding of servers to physical |
| interfaces when interface names were longer than four |
| characters. Thanks to MURASE Katsunori for the patch. |
| |
| Fixed netlink code to check that messages come from the |
| correct source, and not another userspace process. Thanks |
| to Steve Grubb for the patch. |
| |
| Maintainability drive: removed bug and missing feature |
| workarounds for some old platforms. Solaris 9, OpenBSD |
| older than 4.1, Glibc older than 2.2, Linux 2.2.x and |
| DBus older than 1.1.x are no longer supported. |
| |
| Don't read included configuration files more than once: |
| allows complex configuration structures without problems. |
| |
| Mark log messages from the various subsystems in dnsmasq: |
| messages from the DHCP subsystem now have the ident string |
| "dnsmasq-dhcp" and messages from TFTP have ident |
| "dnsmasq-tftp". Thanks to Olaf Westrik for the patch. |
| |
| Fix possible infinite DHCP protocol loop when an IP |
| address nailed to a hostname (not a MAC address) and a |
| host sometimes provides the name, sometimes not. |
| |
| Allow --addn-hosts to take a directory: all the files |
| in the directory are read. Thanks to Phil Cornelius for |
| the suggestion. |
| |
| Support --bridge-interface on all platforms, not just BSD. |
| |
| Added support for advanced PXE functions. It's now |
| possible to define a prompt and menu options which will |
| be displayed when a client PXE boots. It's also possible to |
| hand-off booting to other boot servers. Proxy-DHCP, where |
| dnsmasq just supplies the PXE information and another DHCP |
| server does address allocation, is also allowed. See the |
| --pxe-prompt and --pxe-service keywords. Thanks to |
| Alkis Georgopoulos for the suggestion and Guilherme Moro |
| and Michael Brown for assistance. |
| |
| Improvements to DHCP logging. Thanks to Tom Metro for |
| useful suggestions. |
| |
| Add ability to build dnsmasq without DHCP support. To do |
| this, edit src/config.h or build with |
| "make COPTS=-DNO_DHCP". Thanks to Mahavir Jain for the patch. |
| |
| Added --test command-line switch - syntax check |
| configuration files only. |
| |
| Updated French translation. Thanks to Gildas Le Nadan. |
| |
| |
| version 2.47 |
| Updated French translation. Thanks to Gildas Le Nadan. |
| |
| Fixed interface enumeration code to work on NetBSD |
| 5.0. Thanks to Roy Marples for the patch. |
| |
| Updated config.h to use the same location for the lease |
| file on NetBSD as the other *BSD variants. Also allow |
| LEASEFILE and CONFFILE symbols to be overriden in CFLAGS. |
| |
| Handle duplicate address detection on IPv6 more |
| intelligently. In IPv6, an interface can have an address |
| which is not usable, because it is still undergoing DAD |
| (such addresses are marked "tentative"). Attempting to |
| bind to an address in this state returns an error, |
| EADDRNOTAVAIL. Previously, on getting such an error, |
| dnsmasq would silently abandon the address, and never |
| listen on it. Now, it retries once per second for 20 |
| seconds before generating a fatal error. 20 seconds should |
| be long enough for any DAD process to complete, but can be |
| adjusted in src/config.h if necessary. Thanks to Martin |
| Krafft for the bug report. |
| |
| Add DBus introspection. Patch from Jeremy Laine. |
| |
| Update Dbus configuration file. Patch from Colin Walters. |
| Fix for this bug: |
| http://bugs.freedesktop.org/show_bug.cgi?id=18961 |
| |
| Support arbitrarily encapsulated DHCP options, suggestion |
| and initial patch from Samium Gromoff. This is useful for |
| (eg) gPXE, which expect all its private options to be |
| encapsulated inside a single option 175. So, eg, |
| |
| dhcp-option = encap:175, 190, "iscsi-client0" |
| dhcp-option = encap:175, 191, "iscsi-client0-secret" |
| |
| will provide iSCSI parameters to gPXE. |
| |
| Enhance --dhcp-match to allow testing of the contents of a |
| client-sent option, as well as its presence. This |
| application in mind for this is RFC 4578 |
| client-architecture specifiers, but it's generally useful. |
| Joey Korkames suggested the enhancement. |
| |
| Move from using the IP_XMIT_IF ioctl to IP_BOUND_IF on |
| OpenSolaris. Thanks to Bastian Machek for the heads-up. |
| |
| No longer complain about blank lines in |
| /etc/ethers. Thanks to Jon Nelson for the patch. |
| |
| Fix binding of servers to physical devices, eg |
| --server=/domain/1.2.3.4@eth0 which was broken from 2.43 |
| onwards unless --query-port=0 set. Thanks to Peter Naulls |
| for the bug report. |
| |
| Reply to DHCPINFORM requests even when the supplied ciaddr |
| doesn't fall in any dhcp-range. In this case it's not |
| possible to supply a complete configuration, but |
| individually-configured options (eg PAC) may be useful. |
| |
| Allow the source address of an alias to be a range: |
| --alias=192.168.0.0,10.0.0.0,255.255.255.0 maps the whole |
| subnet 192.168.0.0->192.168.0.255 to 10.0.0.0->10.0.0.255, |
| as before. |
| --alias=192.168.0.10-192.168.0.40,10.0.0.0,255.255.255.0 |
| maps only the 192.168.0.10->192.168.0.40 region. Thanks to |
| Ib Uhrskov for the suggestion. |
| |
| Don't dynamically allocate DHCP addresses which may break |
| Windows. Addresses which end in .255 or .0 are broken in |
| Windows even when using supernetting. |
| --dhcp-range=192.168.0.1,192.168.1.254,255,255,254.0 means |
| 192.168.0.255 is a valid IP address, but not for Windows. |
| See Microsoft KB281579. We therefore no longer allocate |
| these addresses to avoid hard-to-diagnose problems. |
| |
| Update Polish translation. Thanks to Jan Psota. |
| |
| Delete the PID-file when dnsmasq shuts down. Note that by |
| this time, dnsmasq is normally not running as root, so |
| this will fail if the PID-file is stored in a root-owned |
| directory; such failure is silently ignored. To take |
| advantage of this feature, the PID-file must be stored in a |
| directory owned and write-able by the user running |
| dnsmasq. |
| |
| |
| version 2.46 |
| Allow --bootp-dynamic to take a netid tag, so that it may |
| be selectively enabled. Thanks to Olaf Westrik for the |
| suggestion. |
| |
| Remove ISC-leasefile reading code. This has been |
| deprecated for a long time, and last time I removed it, it |
| ended up going back by request of one user. This time, |
| it's gone for good; otherwise it would need to be |
| re-worked to support multiple domains (see below). |
| |
| Support DHCP clients in multiple DNS domains. This is a |
| long-standing request. Clients are assigned to a domain |
| based in their IP address. |
| |
| Add --dhcp-fqdn flag, which changes behaviour if DNS names |
| assigned to DHCP clients. When this is set, there must be |
| a domain associated with each client, and only |
| fully-qualified domain names are added to the DNS. The |
| advantage is that the only the FQDN needs to be unique, |
| so that two or more DHCP clients can share a hostname, as |
| long as they are in different domains. |
| |
| Set environment variable DNSMASQ_DOMAIN when invoking |
| lease-change script. This may be useful information to |
| have now that it's variable. |
| |
| Tighten up data-checking code for DNS packet |
| handling. Thanks to Steve Dodd who found certain illegal |
| packets which could crash dnsmasq. No memory overwrite was |
| possible, so this is not a security issue beyond the DoS |
| potential. |
| |
| Update example config dhcp option 47, the previous |
| suggestion generated an illegal, zero-length, |
| option. Thanks to Matthias Andree for finding this. |
| |
| Rewrite hosts-file reading code to remove the limit of |
| 1024 characters per line. John C Meuser found this. |
| |
| Create a net-id tag with the name of the interface on |
| which the DHCP request was received. |
| |
| Fixed minor memory leak in DBus code, thanks to Jeremy |
| Laine for the patch. |
| |
| Emit DBus signals as the DHCP lease database |
| changes. Thanks to Jeremy Laine for the patch. |
| |
| Allow for more that one MAC address in a dhcp-host |
| line. This configuration tells dnsmasq that it's OK to |
| abandon a DHCP lease of the fixed address to one MAC |
| address, if another MAC address in the dhcp-host statement |
| asks for an address. This is useful to give a fixed |
| address to a host which has two network interfaces |
| (say, a laptop with wired and wireless interfaces.) |
| It's very important to ensure that only one interface |
| at a time is up, since dnsmasq abandons the first lease |
| and re-uses the address before the leased time has |
| elapsed. John Gray suggested this. |
| |
| Tweak the response to a DHCP request packet with a wrong |
| server-id when --dhcp-authoritative is set; dnsmasq now |
| returns a DHCPNAK, rather than silently ignoring the |
| packet. Thanks to Chris Marget for spotting this |
| improvement. |
| |
| Add --cname option. This provides a limited alias |
| function, usable for DHCP names. Thanks to AJ Weber for |
| suggestions on this. |
| |
| Updated contrib/webmin with latest version from Neil |
| Fisher. |
| |
| Updated Polish translation. Thanks to Jan Psota. |
| |
| Correct the text names for DHCP options 64 and 65 to be |
| "nis+-domain" and "nis+-servers". |
| |
| Updated Spanish translation. Thanks to Chris Chatham. |
| |
| Force re-reading of /etc/resolv.conf when an "interface |
| up" event occurs. |
| |
| |
| version 2.45 |
| Fix total DNS failure in release 2.44 unless --min-port |
| specified. Thanks to Steven Barth and Grant Coady for |
| bugreport. Also reject out-of-range port spec, which could |
| break things too: suggestion from Gilles Espinasse. |
| |
| |
| version 2.44 |
| Fix crash when unknown client attempts to renew a DHCP |
| lease, problem introduced in version 2.43. Thanks to |
| Carlos Carvalho for help chasing this down. |
| |
| Fix potential crash when a host which doesn't have a lease |
| does DHCPINFORM. Again introduced in 2.43. This bug has |
| never been reported in the wild. |
| |
| Fix crash in netlink code introduced in 2.43. Thanks to |
| Jean Wolter for finding this. |
| |
| Change implementation of min_port to work even if min-port |
| is large. |
| |
| Patch to enable compilation of latest Mac OS X. Thanks to |
| David Gilman. |
| |
| Update Spanish translation. Thanks to Christopher Chatham. |
| |
| |
| version 2.43 |
| Updated Polish translation. Thanks to Jan Psota. |
| |
| Flag errors when configuration options are repeated |
| illegally. |
| |
| Further tweaks for GNU/kFreeBSD |
| |
| Add --no-wrap to msgmerge call - provides nicer .po file |
| format. |
| |
| Honour lease-time spec in dhcp-host lines even for |
| BOOTP. The user is assumed to known what they are doing in |
| this case. (Hosts without the time spec still get infinite |
| leases for BOOTP, over-riding the default in the |
| dhcp-range.) Thanks to Peter Katzmann for uncovering this. |
| |
| Fix problem matching relay-agent ids. Thanks to Michael |
| Rack for the bug report. |
| |
| Add --naptr-record option. Suggestion from Johan |
| Bergquist. |
| |
| Implement RFC 5107 server-id-override DHCP relay agent |
| option. |
| |
| Apply patches from Stefan Kruger for compilation on |
| Solaris 10 under Sun studio. |
| |
| Yet more tweaking of Linux capability code, to suppress |
| pointless wingeing from kernel 2.6.25 and above. |
| |
| Improve error checking during startup. Previously, some |
| errors which occurred during startup would be worked |
| around, with dnsmasq still starting up. Some were logged, |
| some silent. Now, they all cause a fatal error and dnsmasq |
| terminates with a non-zero exit code. The errors are those |
| associated with changing uid and gid, setting process |
| capabilities and writing the pidfile. Thanks to Uwe |
| Gansert and the Suse security team for pointing out |
| this improvement, and Bill Reimers for good implementation |
| suggestions. |
| |
| Provide NO_LARGEFILE compile option to switch off largefile |
| support when compiling against versions of uclibc which |
| don't support it. Thanks to Stephane Billiart for the patch. |
| |
| Implement random source ports for interactions with |
| upstream nameservers. New spoofing attacks have been found |
| against nameservers which do not do this, though it is not |
| clear if dnsmasq is vulnerable, since to doesn't implement |
| recursion. By default dnsmasq will now use a different |
| source port (and socket) for each query it sends |
| upstream. This behaviour can suppressed using the |
| --query-port option, and the old default behaviour |
| restored using --query-port=0. Explicit source-port |
| specifications in --server configs are still honoured. |
| |
| Replace the random number generator, for better |
| security. On most BSD systems, dnsmasq uses the |
| arc4random() RNG, which is secure, but on other platforms, |
| it relied on the C-library RNG, which may be |
| guessable and therefore allow spoofing. This release |
| replaces the libc RNG with the SURF RNG, from Daniel |
| J. Berstein's DJBDNS package. |
| |
| Don't attempt to change user or group or set capabilities |
| if dnsmasq is run as a non-root user. Without this, the |
| change from soft to hard errors when these fail causes |
| problems for non-root daemons listening on high |
| ports. Thanks to Patrick McLean for spotting this. |
| |
| Updated French translation. Thanks to Gildas Le Nadan. |
| |
