DNS轻量级缓存服务dnsmasq发布2.67版本。2013-10-26 上一个版本是2013-04-17的2.66。经过4个RC 可以用它做DNS代理缓存及内网hosts主机名的集中管理使用(也可以做DHCP)，非常好用。
version 2.67 Fix crash if upstream server returns SERVFAIL when --conntrack in use. Thanks to Giacomo Tazzari for finding this and supplying the patch. Repair regression in 2.64. That release stopped sending lease-time information in the reply to DHCPINFORM requests, on the correct grounds that it was a standards violation. However, this broke the dnsmasq-specific dhcp_lease_time utility. Now, DHCPINFORM returns lease-time only if it's specifically requested (maintaining standards) and the dhcp_lease_time utility has been taught to ask for it (restoring functionality). Fix --dhcp-match, --dhcp-vendorclass and --dhcp-userclass to work with BOOTP and well as DHCP. Thanks to Peter Korsgaard for spotting the problem. Add --synth-domain. Thanks to Vishvananda Ishaya for suggesting this. Fix failure to compile ipset.c if old kernel headers are in use. Thanks to Eugene Rudoy for pointing this out. Handle IPv4 interface-address labels in Linux. These are often used to emulate the old IP-alias addresses. Before, using --interface=eth0 would service all the addresses of eth0, including ones configured as aliases, which appear in ifconfig as eth0:0. Now, only addresses with the label eth0 are active. This is not backwards compatible: if you want to continue to bind the aliases too, you need to add eg. --interface=eth0:0 to the config. Fix "failed to set SO_BINDTODEVICE on DHCP socket: Socket operation on non-socket" error on startup with configurations which have exactly one --interface option and do RA but _not_ DHCPv6. Thanks to Trever Adams for the bug report. Generalise --interface-name to cope with IPv6 addresses and multiple addresses per interface per address family. Fix option parsing for --dhcp-host, which was generating a spurious error when all seven possible items were included. Thanks to Zhiqiang Wang for the bug report. Remove restriction on prefix-length in --auth-zone. Thanks to Toke Hoiland-Jorgensen for suggesting this. Log when the maximum number of concurrent DNS queries is reached. Thanks to Marcelo Salhab Brogliato for the patch. If wildcards are used in --interface, don't assume that there will only ever be one available interface for DHCP just because there is one at start-up. More may appear, so we can't use SO_BINDTODEVICE. Thanks to Natrio for the bug report. Increase timeout/number of retries in TFTP to accomodate AudioCodes Voice Gateways doing streaming writes to flash. Thanks to Damian Kaczkowski for spotting the problem. Fix crash with empty DHCP string options when adding zero terminator. Thanks to Patrick McLean for the bug report. Allow hostnames to start with a number, as allowed in RFC-1123. Thanks to Kyle Mestery for the patch. Fixes to DHCP FQDN option handling: don't terminate FQDN if domain not known and allow a FQDN option with blank name to request that a FQDN option is returned in the reply. Thanks to Roy Marples for the patch. Make --clear-on-reload apply to setting upstream servers via DBus too. When the address which triggered the construction of an advertised IPv6 prefix disappears, continue to advertise the prefix for up to 2 hours, with the preferred lifetime set to zero. This satisfies RFC 6204 4.3 L-13 and makes things work better if a prefix disappears without being deprecated first. Thanks to Uwe Schindler for persuasively arguing for this. Fix MAC address enumeration on *BSD. Thanks to Brad Smith for the bug report. Support RFC-4242 information-refresh-time options in the reply to DHCPv6 information-request. The lease time of the smallest valid dhcp-range is sent. Thanks to Uwe Schindler for suggesting this. Make --listen-address higher priority than --except-interface in all circumstances. Thanks to Thomas Hood for the bugreport. Provide independent control over which interfaces get TFTP service. If enable-tftp is given a list of interfaces, then TFTP is provided on those. Without the list, the previous behaviour (provide TFTP to the same interfaces we provide DHCP to) is retained. Thanks to Lonnie Abelbeck for the suggestion. Add --dhcp-relay config option. Many thanks to vtsl.net for sponsoring this development. Fix crash with empty tag: in --dhcp-range. Thanks to Kaspar Schleiser for the bug report. Add "baseline" and "bloatcheck" makefile targets, for revealing size changes during development. Thanks to Vladislav Grishenko for the patch. Cope with DHCPv6 clients which send REQUESTs without address options - treat them as SOLICIT with rapid commit. Support identification of clients by MAC address in DHCPv6. When using a relay, the relay must support RFC 6939 for this to work. It always works for directly connected clients. Thanks to Vladislav Grishenko for prompting this feature. Remove the rule for constructed DHCP ranges that the local address must be either the first or last address in the range. This was originally to avoid SLAAC addresses, but we now explicitly autoconfig and privacy addresses instead. Update Polish translation. Thanks to Jan Psota. Fix problem in DHCPv6 vendorclass/userclass matching code. Thanks to Tanguy Bouzeloc for the patch. Update Spanish transalation. Thanks to Vicente Soriano. Add --ra-param option. Thanks to Vladislav Grishenko for inspiration on this. Add --add-subnet configuration, to tell upstream DNS servers where the original client is. Thanks to DNSthingy for sponsoring this feature. Add --quiet-dhcp, --quiet-dhcp6 and --quiet-ra. Thanks to Kevin Darbyshire-Bryant for the initial patch. Allow A/AAAA records created by --interface-name to be the target of --cname. Thanks to Hadmut Danisch for the suggestion. Avoid treating a --dhcp-host which has an IPv6 address as eligable for use with DHCPv4 on the grounds that it has no address, and vice-versa. Thanks to Yury Konovalov for spotting the problem. Do a better job caching dangling CNAMEs. Thanks to Yves Dorfsman for spotting the problem.
