| version 2.60 |
| Fix compilation problem in Mac OS X Lion. Thanks to Olaf |
| Flebbe for the patch. |
| |
| Fix DHCP when using --listen-address with an IP address |
| which is not the primary address of an interface. |
| |
| Add --dhcp-client-update option. |
| |
| Add Lua integration. Dnsmasq can now execute a DHCP |
| lease-change script written in Lua. This needs to be |
| enabled at compile time by setting HAVE_LUASCRIPT in |
| src/config.h or running "make COPTS=-DHAVE_LUASCRIPT" |
| Thanks to Jan-Piet Mens for the idea and proof-of-concept |
| implementation. |
| |
| Tidied src/config.h to distinguish between |
| platform-dependent compile-time options which are selected |
| automatically, and builder-selectable compile time |
| options. Document the latter better, and describe how to |
| set them from the make command line. |
| |
| Tidied up IPPROTO_IP/SOL_IP (and IPv6 equivalent) |
| confusion. IPPROTO_IP works everywhere now. |
| |
| Set TOS on DHCP sockets, this improves things on busy |
| wireless networks. Thanks to Dave Taht for the patch. |
| |
| Determine VERSION automatically based on git magic: |
| release tags or hash values. |
| |
| |
| version 2.59 |
| Fix regression in 2.58 which caused failure to start up |
| with some combinations of dnsmasq config and IPv6 kernel |
| network config. Thanks to Brielle Bruns for the bug |
| report. |
| |
| Improve dnsmasq's behaviour when network interfaces are |
| still doing duplicate address detection (DAD). Previously, |
| dnsmasq would wait up to 20 seconds at start-up for the |
| DAD state to terminate. This is broken for bridge |
| interfaces on recent Linux kernels, which don't start DAD |
| until the bridge comes up, and so can take arbitrary |
| time. The new behaviour lets dnsmasq poll for an arbitrary |
| time whilst providing service on other interfaces. Thanks |
| to Stephen Hemminger for pointing out the problem. |
| |
| |
| version 2.58 |
| Provide a definition of the SA_SIZE macro where it's |
| missing. Fixes build failure on openBSD. |
| |
| Don't include a zero terminator at the end of messages |
| sent to /dev/log when /dev/log is a datagram socket. |
| Thanks to Didier Rabound for spotting the problem. |
| |
| Add --dhcp-sequential-ip flag, to force allocation of IP |
| addresses in ascending order. Note that the default |
| pseudo-random mode is in general better but some |
| server-deployment applications need this. |
| |
| Fix problem where a server-id of 0.0.0.0 is sent to a |
| client when a dhcp-relay is in use if a client renews a |
| lease after dnsmasq restart and before any clients on the |
| subnet get a new lease. Thanks to Mike Ruiz for assistance |
| in chasing this one down. |
| |
| Don't return NXDOMAIN to an AAAA query if we have CNAME |
| which points to an A record only: NODATA is the correct |
| reply in this case. Thanks to Tom Fernandes for spotting |
| the problem. |
| |
| Relax the need to supply a netmask in --dhcp-range for |
| networks which use a DHCP relay. Whilst this is still |
| desireable, in the absence of a netmask dnsmasq will use |
| a default based on the class (A, B, or C) of the address. |
| This should at least remove a cause of mysterious failure |
| for people using RFC1918 addresses and relays. |
| |
| Add support for Linux conntrack connection marking. If |
| enabled with --conntrack, the connection mark for incoming |
| DNS queries will be copied to the outgoing connections |
| used to answer those queries. This allows clever firewall |
| and accounting stuff. Only available if dnsmasq is |
| compiled with HAVE_CONNTRACK and adds a dependency on |
| libnetfilter-conntrack. Thanks to Ed Wildgoose for the |
| initial idea, testing and sponsorship of this function. |
| |
| Provide a sane error message when someone attempts to |
| match a tag in --dhcp-host. |
| |
| Tweak the behaviour of --domain-needed, to avoid problems |
| with recursive nameservers downstream of dnsmasq. The new |
| behaviour only stops A and AAAA queries, and returns |
| NODATA rather than NXDOMAIN replies. |
| |
| Efficiency fix for very large DHCP configurations, thanks |
| to James Gartrell and Mike Ruiz for help with this. |
| |
| Allow the TFTP-server address in --dhcp-boot to be a |
| domain-name which is looked up in /etc/hosts. This can |
| give multiple IP addresses which are used round-robin, |
| thus doing TFTP server load-balancing. Thanks to Sushil |
| Agrawal for the patch. |
| |
| When two tagged dhcp-options for a particular option |
| number are both valid, use the one which is valid without |
| a tag from the dhcp-range. Allows overriding of the value |
| of a DHCP option for a particular host as well as |
| per-network values. So |
| --dhcp-range=set:interface1,...... |
| --dhcp-host=set:myhost,..... |
| --dhcp-option=tag:interface1,option:nis-domain,"domain1" |
| --dhcp-option=tag:myhost,option:nis-domain,"domain2" |
| will set the NIS-domain to domain1 for hosts in the range, but |
| override that to domain2 for a particular host. |
| |
| Fix bug which resulted in truncated files and timeouts for |
| some TFTP transfers. The bug only occurs with netascii |
| transfers and needs an unfortunate relationship between |
| file size, blocksize and the number of newlines in the |
| last block before it manifests itself. Many thanks to |
| Alkis Georgopoulos for spotting the problem and providing |
| a comprehensive test-case. |
| |
| Fix regression in TFTP server on *BSD platforms introduced |
| in version 2.56, due to confusion with sockaddr |
| length. Many thanks to Loïc Pefferkorn for finding this. |
| |
| Support scope-ids in IPv6 addresses of nameservers from |
| /etc/resolv.conf and in --server options. Eg |
| nameserver fe80::202:a412:4512:7bbf%eth0 or |
| server=fe80::202:a412:4512:7bbf%eth0. Thanks to |
| Michael Stapelberg for the suggestion. |
| |
| Update Polish translation, thanks to Jan Psota. |
| |
| Update French translation. Thanks to Gildas Le Nadan. |
| |
| |
| version 2.57 |
| Add patches to allow build under Android. |
| |
| Provide our own header for the DNS protocol, rather than |
| relying on arpa/nameser.h. This has proved more or less |
| defective over the years and the final straw is that it's |
| effectively empty on Android. |
| |
| Fix regression in 2.56 which caused hex constants in |
| configuration to be rejected if they contain the '*' |
| wildcard. |
| |
| Correct wrong casts of arguments to ctype.h functions, |
| isdigit(), isxdigit() etc. Thanks to Matthias Andree for |
| spotting this. |
| |
| Allow build with IDN support independently from i18n. |
| IDN support continues to be included automatically |
| when i18n is included. |
| 'make COPTS=-DHAVE_IDN' is the magic incantation. |
| |
| Modify check on extraneous command line junk (added in |
| 2.56) so that it doesn't complain about extra _empty_ |
| arguments. Otherwise this breaks libvirt. |
| |
| |
| version 2.56 |
| Add a patch to allow dnsmasq to get interface names right in a |
| Solaris zone. Thanks to Dj Padzensky for this. |
| |
| Improve data-type parsing heuristics so that |
| --dhcp-option=option:domain-search,. |
| treats the value as a string and not an IP address. |
| Thanks to Clemens Fischer for spotting that. |
| |
| Add IPv6 support to the TFTP server. Many thanks to Jan |
| 'RedBully' Seiffert for the patches. |
| |
| Log DNS queries at level LOG_INFO, rather then |
| LOG_DEBUG. This makes things consistent with DHCP |
| logging. Thanks to Adam Pribyl for spotting the problem. |
| |
| Ensure that dnsmasq terminates cleanly when using |
| --syslog-async even if it cannot make a connection to the |
| syslogd. |
| |
| Add --add-mac option. This is to support currently |
| experimental DNS filtering facilities. Thanks to Benjamin |
| Petrin for the orignal patch. |
| |
| Fix bug which meant that tags were ignored in dhcp-range |
| configuration specifying PXE-proxy service. Thanks to |
| Cristiano Cumer for spotting this. |
| |
| Raise an error if there is extra junk, not part of an |
| option, on the command line. |
| |
| Flag a couple of log messages in cache.c as coming from |
| the DHCP subsystem. Thanks to Olaf Westrik for the patch. |
| |
| Omit timestamps from logs when a) logging to stderr and |
| b) --keep-in-forground is set. The logging facility on the |
| other end of stderr can be assumned to supply them. Thanks |
| to John Hallam for the patch. |
| |
| Don't complain about strings longer than 255 characters in |
| --txt-record, just split the long strings into 255 |
| character chunks instead. |
| |
| Fix crash on double-free. This bug can only happen when |
| dhcp-script is in use and then only in rare circumstances |
| triggered by high DHCP transaction rate and a slow |
| script. Thanks to Ferenc Wagner for finding the problem. |
| |
| Only log that a file has been sent by TFTP after the |
| transfer has completed succesfully. |
| |
| A good suggestion from Ferenc Wagner: extend |
| the --domain option to allow this sort of thing: |
| --domain=thekelleys.org.uk,192.168.0.0/24,local |
| which automatically creates |
| --local=/thekelleys.org.uk/ |
| --local=/0.168.192.in-addr.arpa/ |
| |
| Tighten up syntax checking of hex contants in the config |
| file. Thanks to Fred Damen for spotting this. |
| |
| Add dnsmasq logo/icon, contributed by Justin Swift. Many |
| thanks for that. |
| |
| Never cache DNS replies which have the 'cd' bit set, or |
| which result from queries forwarded with the 'cd' bit |
| set. The 'cd' bit instructs a DNSSEC validating server |
| upstream to ignore signature failures and return replies |
| anyway. Without this change it's possible to pollute the |
| dnsmasq cache with bad data by making a query with the |
| 'cd' bit set and subsequent queries would return this data |
| without its being marked as suspect. Thanks to Anders |
| Kaseorg for pointing out this problem. |
| |
| Add --proxy-dnssec flag, for compliance with RFC |
| 4035. Dnsmasq will now clear the 'ad' bit in answers returned |
| from upstream validating nameservers unless this option is |
| set. |
| |
| Allow a filename of "-" for --conf-file to read |
| stdin. Suggestion from Timothy Redaelli. |
| |
| Rotate the order of SRV records in replies, to provide |
| round-robin load balancing when all the priorities are |
| equal. Thanks to Peter McKinney for the suggestion. |
| |
| Edit |
| contrib/MacOSX-launchd/uk.org.thekelleys.dnsmasq.plist |
| so that it doesn't log all queries to a file by |
| default. Thanks again to Peter McKinney. |
| |
| By default, setting an IPv4 address for a domain but not |
| an IPv6 address causes dnsmasq to return |
| an NODATA reply for IPv6 (or vice-versa). So |
| --address=/google.com/1.2.3.4 stops IPv6 queries for |
| *google.com from being forwarded. Make it possible to |
| override this behaviour by defining the sematics if the |
| same domain appears in both --server and --address. |
| In that case, the --address has priority for the address |
| family in which is appears, but the --server has priority |
| of the address family which doesn't appear in --adddress |
| So: |
| --address=/google.com/1.2.3.4 |
| --server=/google.com/# |
| will return 1.2.3.4 for IPv4 queries for *.google.com but |
| forward IPv6 queries to the normal upstream nameserver. |
| Similarly when setting an IPv6 address |
| only this will allow forwarding of IPv4 queries. Thanks to |
| William for pointing out the need for this. |
| |
| Allow more than one --dhcp-optsfile and --dhcp-hostsfile |
| and make them understand directories as arguments in the |
| same way as --addn-hosts. Suggestion from John Hanks. |
| |
| Ignore rebinding requests for leases we don't know |
| about. Rebind is broadcast, so we might get to overhear a |
| request meant for another DHCP server. NAKing this is |
| wrong. Thanks to Brad D'Hondt for assistance with this. |
| |
| Fix cosmetic bug which produced strange output when |
| dumping cache statistics with some configurations. Thanks |
| to Fedor Kozhevnikov for spotting this. |
| |
| |
| version 2.55 |
| Fix crash when /etc/ethers is in use. Thanks to |
| Gianluigi Tiesi for finding this. |
| |
| Fix crash in netlink_multicast(). Thanks to Arno Wald for |
| finding this one. |
| |
| Allow the empty domain "." in dhcp domain-search (119) |
| options. |
| |
| |
| version 2.54 |
| There is no version 2.54 to avoid confusion with 2.53, |
| which incorrectly identifies itself as 2.54. |
| |
| |
| version 2.53 |
| Fix failure to compile on Debian/kFreeBSD. Thanks to |
| Axel Beckert and Petr Salinger. |
| |
| Fix code to avoid scary strict-aliasing warnings |
| generated by gcc 4.4. |
| |
| Added FAQ entry warning about DHCP failures with Vista |
| when firewalls block 255.255.255.255. |
| |
| Fixed bug which caused bad things to happen if a |
| resolv.conf file which exists is subsequently removed. |
| Thanks to Nikolai Saoukh for the patch. |
| |
| Rationalised the DHCP tag system. Every configuration item |
| which can set a tag does so by adding "set:<tag>" and |
| every configuration item which is conditional on a tag is |
| made so by "tag:<tag>". The NOT operator changes to '!', |
| which is a bit more intuitive too. Dhcp-host directives |
| can set more than one tag now. The old '#' NOT, |
| "net:" prefix and no-prefixes are still honoured, so |
| no existing config file needs to be changed, but |
| the documentation and new-style config files should be |
| much less confusing. |
| |
| Added --tag-if to allow boolean operations on tags. |
| This allows complicated logic to be clearer and more |
| general. A great suggestion from Richard Voigt. |
| |
| Add broadcast/unicast information to DHCP logging. |
| |
| Allow --dhcp-broadcast to be unconditional. |
| |
| Fixed incorrect behaviour with NOT <tag> conditionals in |
| dhcp-options. Thanks to Max Turkewitz for assistance |
| finding this. |
| |
| If we send vendor-class encapsulated options based on the |
| vendor-class supplied by the client, and no explicit |
| vendor-class option is given, echo back the vendor-class |
| from the client. |
| |
| Fix bug which stopped dnsmasq from matching both a |
| circuitid and a remoteid. Thanks to Ignacio Bravo for |
| finding this. |
| |
| Add --dhcp-proxy, which makes it possible to configure |
| dnsmasq to use a DHCP relay agent as a full proxy, with |
| all DHCP messages passing through the proxy. This is |
| useful if the relay adds extra information to the packets |
| it forwards, but cannot be configured with the RFC 5107 |
| server-override option. |
| |
| Added interface:<iface name> part to dhcp-range. The |
| semantics of this are very odd at first sight, but it |
| allows a single line of the form |
| dhcp-range=interface:virt0,192.168.0.4,192.168.0.200 |
| to be added to dnsmasq configuration which then supplies |
| DHCP and DNS services to that interface, without affecting |
| what services are supplied to other interfaces and |
| irrespective of the existance or lack of |
| interface=<interface> |
| lines elsewhere in the dnsmasq configuration. The idea is |
| that such a line can be added automatically by libvirt |
| or equivalent systems, without disturbing any manual |
| configuration. |
| |
| Similarly to the above, allow --enable-tftp=<interface> |
| |
| Allow a TFTP root to be set separately for requests via |
| different interfaces, --tftp-root=<path>,<interface> |
| |
| Correctly handle and log clashes between CNAMES and |
| DNS names being given to DHCP leases. This fixes a bug |
| which caused nonsense IP addresses to be logged. Thanks to |
| Sergei Zhirikov for finding and analysing the problem. |
| |
| Tweak flush_log so as to avoid leaving the log |
| file in non-blocking mode. O_NONBLOCK is a property of the |
| file, not the process/descriptor. |
| |
| Fix contrib/Solaris10/create_package |
| (/usr/man -> /usr/share/man) Thanks to Vita Batrla. |
| |
| Fix a problem where, if a client got a lease, then went |
| to another subnet and got another lease, then moved back, |
| it couldn't resume the old lease, but would instead get |
| a new address. Thanks to Leonardo Rodrigues for spotting |
| this and testing the fix. |
| |
| Fix weird bug which sometimes omitted certain characters |
| from the start of quoted strings in dhcp-options. Thanks |
| to Dayton Turner for spotting the problem. |
| |
| Add facility to redirect some domains to the standard |
| upstream servers: this allows something like |
| --server=/google.com/1.2.3.4 --server=/www.google.com/# |
| which will send queries for *.google.com to 1.2.3.4, |
| except *www.google.com which will be forwarded as usual. |
| Thanks to AJ Weber for prompting this addition. |
| |
| Improve the hash-algorithm used to generate IP addresses |
| from MAC addresses during initial DHCP address |
| allocation. This improves performance when large numbers |
| of hosts with similar MAC addresses all try and get an IP |
| address at the same time. Thanks to Paul Smith for his |
| work on this. |
| |
| Tweak DHCP code so that --bridge-interface can be used to |
| select which IP alias of an interface should be used for |
| DHCP purposes on Linux. If eth0 has an alias eth0:dhcp |
| then adding --bridge-interface=eth0:dhcp,eth0 will use |
| the address of eth0:dhcp to determine the correct subnet |
| for DHCP address allocation. Thanks to Pawel Golaszewski |
| for prompting this and Eric Cooper for further testing. |
| |
| Add --dhcp-generate-names. Suggestion by Ferenc Wagner. |
| |
| Tweak DNS server selection algorithm when there is more |
| than one server available for a domain, eg. |
| --server=/mydomain/1.1.1.1 |
| --server=/mydomain/2.2.2.2 |
| Thanks to Alberto Cuesta-Canada for spotting a weakness |
| here. |
| |
| Add --max-ttl. Thanks to Fredrik Ringertz for the patch. |
| |
| Allow --log-facility=- to force all logging to |
| stderr. Suggestion from Clemens Fischer. |
| |
| Fix regression which caused configuration like |
| --address=/.domain.com/1.2.3.4 to be rejected. The dot to the |
| left of the domain has been implied and not required for a |
| long time, but it should be accepted for backward |
| compatibility. Thanks to Andrew Burcin for spotting this. |
| |
| Add --rebind-domain-ok and --rebind-localhost-ok. |
| Suggestion from Clemens Fischer. |
| |
| Log replies to queries of type TXT, when --log-queries |
| is set. |
| |
| Fix compiler warnings when compiled with -DNO_DHCP. Thanks |
| to Shantanu Gadgil for the patch. |
| |
| Updated French translation. Thanks to Gildas Le Nadan. |
| |
| Updated Polish translation. Thanks to Jan Psota. |
| |
| Updated German translation. Thanks to Matthias Andree. |
| |
| Added contrib/static-arp, thanks to Darren Hoo. |
| |
| Fix corruption of the domain when a name from /etc/hosts |
| overrides one supplied by a DHCP client. Thanks to Fedor |
| Kozhevnikov for spotting the problem. |
| |
| Updated Spanish translation. Thanks to Chris Chatham. |
| |
| |
| version 2.52 |
| Work around a Linux kernel bug which insists that the |
| length of the option passed to setsockopt must be at least |
| sizeof(int) bytes, even if we're calling SO_BINDTODEVICE |
| and the device name is "lo". Note that this is fixed |
| in kernel 2.6.31, but the workaround is harmless and |
| allows earlier kernels to be used. Also fix dnsmasq |
| bug which reported the wrong address when this failed. |
| Thanks to Fedor for finding this. |
| |
| The API for IPv6 PKTINFO changed around Linux kernel |
| 2.6.14. Workaround the case where dnsmasq is compiled |
| against newer headers, but then run on an old kernel: |
| necessary for some *WRT distros. |
| |
| Re-read the set of network interfaces when re-loading |
| /etc/resolv.conf if --bind-interfaces is not set. This |
| handles the case that loopback interfaces do not exist |
| when dnsmasq is first started. |
| |
| Tweak the PXE code to support port 4011. This should |
| reduce broadcasts and make things more reliable when other |
| servers are around. It also improves inter-operability |
| with certain clients. |
| |
| Make a pxe-service configuration with no filename or boot |
| service type legal: this does a local boot. eg. |
| pxe-service=x86PC, "Local boot" |
| |
| Be more conservative in detecting "A for A" |
| queries. Dnsmasq checks if the name in a type=A query looks |
| like a dotted-quad IP address and answers the query itself |
| if so, rather than forwarding it. Previously dnsmasq |
| relied in the library function inet_addr() to convert |
| addresses, and that will accept some things which are |
| confusing in this context, like 1.2.3 or even just |
| 1234. Now we only do A for A processing for four decimal |
| numbers delimited by dots. |
| |
| A couple of tweaks to fix compilation on Solaris. Thanks |
| to Joel Macklow for help with this. |
| |
| Another Solaris compilation tweak, needed for Solaris |
| 2009.06. Thanks to Lee Essen for that. |
| |
| Added extract packaging stuff from Lee Essen to |
| contrib/Solaris10. |
| |
| Increased the default limit on number of leases to 1000 |
| (from 150). This is mainly a defence against DoS attacks, |
| and for the average "one for two class C networks" |
| installation, IP address exhaustion does that just as |
| well. Making the limit greater than the number of IP |
| addresses available in such an installation removes a |
| surprise which otherwise can catch people out. |
| |
| Removed extraneous trailing space in the value of the |
| DNSMASQ_TIME_REMAINING DNSMASQ_LEASE_LENGTH and |
| DNSMASQ_LEASE_EXPIRES environment variables. Thanks to |
| Gildas Le Nadan for spotting this. |
| |
| Provide the network-id tags for a DHCP transaction to |
| the lease-change script in the environment variable |
| DNSMASQ_TAGS. A good suggestion from Gildas Le Nadan. |
| |
| Add support for RFC3925 "Vendor-Identifying Vendor |
| Options". The syntax looks like this: |
| --dhcp-option=vi-encap:<enterprise number>, ......... |
| |
| Add support to --dhcp-match to allow matching against |
| RFC3925 "Vendor-Identifying Vendor Classes". The syntax |
| looks like this: |
| --dhcp-match=tag,vi-encap<enterprise number>, <value> |
| |
| Add some application specific code to assist in |
| implementing the Broadband forum TR069 CPE-WAN |
| specification. The details are in contrib/CPE-WAN/README |
| |
| Increase the default DNS packet size limit to 4096, as |
| recommended by RFC5625 section 4.4.3. This can be |
| reconfigured using --edns-packet-max if needed. Thanks to |
| Francis Dupont for pointing this out. |
| |
| Rewrite query-ids even for TSIG signed packets, since |
| this is allowed by RFC5625 section 4.5. |
| |
| Use getopt_long by default on OS X. It has been supported |
| since version 10.3.0. Thanks to Arek Dreyer for spotting |
| this. |
| |
| Added up-to-date startup configuration for MacOSX/launchd |
| in contrib/MacOSX-launchd. Thanks to Arek Dreyer for |
| providing this. |
| |
| Fix link error when including Dbus but excluding DHCP. |
| Thanks to Oschtan for the bug report. |
| |
| Updated French translation. Thanks to Gildas Le Nadan. |
| |
| Updated Polish translation. Thanks to Jan Psota. |
| |
| Updated Spanish translation. Thanks to Chris Chatham. |
| |
| Fixed confusion about domains, when looking up DHCP hosts |
| in /etc/hosts. This could cause spurious "Ignoring |
| domain..." messages. Thanks to Fedor Kozhevnikov for |
| finding and analysing the problem. |
| |
| |
| 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. |
