Fix "install" makefile target. (reported by Rob Stevens)
Ensure that "local=/domain/" flag is obeyed for all
queries on a domain, not just A and AAAA. (Reported by
Peter Fichtner.)
Handle DHCPDECLINE messages and provide an error message
in DHCPNAK messages.
Add "domain" setting example to
dnsmasq.conf.example. Thanks to K P Kirchdorfer for
spotting that it was missing.
Subtle change to the DHCPREQUEST handling code to work
around a bug in the DHCP client in HP Jetdirect printers.
Thanks to Marko Stolle for finding this problem.
Return DHCP T1 and T2 times, with "fuzz" to desychronise lease
renewals, as specified in the RFC.
Ensure that the END option is always present in DHCP
packets , even if the packet is too small to fit all
the requested options.
Handle larger-than-default DHCP packets if required, up
to the ethernet MTU.
Fix a couple of places where the return code from
malloc() was not checked.
Cope with a machine taking a DHCP lease and then moving
network so that the lease address is no longer valid.
The DHCP server will now work via a BOOTP relay - remote
networks are configured with the dhcp-range option the
same as directly connected ones, but they need an
additional netmask parameter. Eg
--dhcp-range=192.168.4.10,192.168.4.50,255.255,255.0
will enable DHCP service via a BOOTP relay on the
192.168.4.0 network.
Add a limit on the number of available DHCP leases,
otherwise the daemon could be DOSed by a malicious
host. The default is 150, but it can be changed by the
dhcp-lease-max option.
Fixed compilation on OpenBSD (thanks to Frederic Brodbeck
for help with that.)
Reworked the DHCP network handling code for two good
effects: (1) The limit of one network only for DHCP on
FreeBSD is now gone, (2) The DHCP server copes with
dynamically created interfaces. The one-interface
limitation remains for OpenBSD, which is missing
extensions to the socket API which have been in Linux
since version 2.2 and FreeBSD since version 4.8.
Reworked the DNS network code to also cope with
dynamically created interfaces. dnsmasq will now listen
to the wildcard address and port 53 by default, so if no
--interface or --address options are given it will handle
dynamically created interfaces. The old behaviour can be
restored with --bind-interfaces for people running BIND
on one interface and dnsmasq on another. Note that
--interface and --address options still work, but the
filtering is done by dnsmasq, rather then the kernel.
This works on Linux, and FreeBSD>=5.0. On systems which
don't support the required API extensions, the old
behaviour is used, just as if --bind-interfaces had been set.
Allow IPv6 support to be disabled at compile time. To do
that, add -DNO_IPV6 to the CFLAGS. Thanks to Oleg
I. Vdovikin for the suggestion to do that.
Add ability to set DHCP options per network. This is done
by giving a network an identifier like this:
dhcp-range=red-net,192.168.0.10,192.168.0.50
and then labeling options intended for that network only
like this:
dhcp-option=red-net,6,1.1.1.1
Thanks to Oleg Vdovikin for arguing that one through.
Made errors in the configuration file non-fatal: dnsmasq
will now complain bitterly, but continue.
Added --read-ethers option, to allow dnsmasq to pull
static DHCP information from that file.
Thanks to Andi Cambeis for that suggestion.
Added HAVE_BROKEN_RTC compilation option to support
embedded systems without a stable RTC. Oleg Vdovikin
helped work out how to make that work.
Move default config file under FreeBSD.
