If a DNS server replies REFUSED for a given DNS query in strict order mode
no failover to the next DNS server is triggered as the failover logic only
covers non strict mode.
As a result the client will be returned the REFUSED reply without first
falling back to the secondary DNS server(s).
Make failover support work as well for strict mode config in case REFUSED is
replied by deleting the strict order check and rely only on forwardall being
equal to 0 which is the case in non strict mode when a single server has been
contacted or when strict order mode has been configured.
Remove historic automatic inclusion of IDN support when
building internationalisation support. This doesn't
fit now there is a choice of IDN libraries. Be sure
to include either -DHAVE_IDN or _DHAVE_LIBIDN2 for
IDN support
This reverts commit 88a77a78ad.
A least one client has been found which breaks with this change. Since
the use-case is not clear, I'm reverting the change, at least for now.
Adds option to delay replying to DHCP packets by one or more seconds.
This provides a workaround for a PXE boot firmware implementation
that has a bug causing it to fail if it receives a (proxy) DHCP
reply instantly.
On Linux it looks up the exact receive time of the UDP packet with
the SIOCGSTAMP ioctl to prevent multiple delays if multiple packets
come in around the same time.
It is currently only possible to let the TFTP server serve a different
folder depending on the client's IP address.
However it isn't always possible to predict what the client's
IP address will be, especially in situations in which we are not
responsible for handing them out (e.g. proxy dhcp setups).
Extend the current --tftp-unique-root parameter to support having a
separate folder per MAC address instead.
By default 30 first servers are listed individually to system log, and
then a count of the remaining items. With e.g. a NXDOMAIN based adblock
service, dnsmasq lists 30 unnecessary ad sites every time when dnsmasq
evaluates the list. But the actual nameservers in use are evaluated last
and are not displayed as they get included in the "remaining items" total.
Handle the "local addresses only" separately and list only a few of them.
Remove the "local addresses only" from the general count.
