Tweaked DHCP behaviour when a client attempts to renew a
lease which dnsmasq doesn't know about. Previously
would always result in a DHCPNAK. Now, in dhcp-authoritative
mode, the lease will be created, if it's legal. This makes
dnsmasq work better if the lease database is lost, for
example on an OpenWRT system which reboots. Thanks to
Stephen Rose for work on this.
Added the ability to support RFC-3442 style destination
descriptors in dhcp-options. This makes classless static
routes easy to do, eg dhcp-option=121,192.168.1.0/24,220.127.116.11
Added error-checking to the code which writes the lease
file. If this fails for any reason, an error is logged,
and a retry occurs after one minute. This should improve
things eg when a filesystem is full. Thanks to Jens Holze
for the bug report.
Fixed breakage of the "/#/ matches any domain" facility
which happened in 2.24. Thanks to Peter Surda for the bug
Use "size_t" and "ssize_t" types where appropriate in the
Fix buggy CNAME handling in mixed IPv4 and IPv6
queries. Thanks to Andreas Pelme for help finding that.
Added some code to attempt to re-transmit DNS queries when
a network interface comes up. This helps on DoD links,
where frequently the packet which triggers dialling is
a DNS query, which then gets lost. By re-sending, we can
avoid the lookup failing. This function is only active
when netlink support is compiled in, and therefore only
under Linux. Thanks to Jean Wolter for help with this.
Tweaked the DHCP tag-matching code to work correctly with
NOT-tag conditions. Thanks to Lutz Pressler for finding
Generalised netid-tag matching in dhcp-range statements to
allow more than one tag.
Added --dhcp-mac to do MAC address matching in the same
way as vendorclass and userclass matching. A good
suggestion from Lutz Pressler.
Add workaround for buggy early Microsoft DHCP clients
which need zero-termination in string options.
Thanks to Fabiano Pires for help with this.
Generalised the DHCP code to cope with any hardware
address type, at least on Linux. *BSD is still limited to
