Commit f77700aa, which fixes a compiler warning, also breaks the
behaviour of prepending ".<layer>" to basenames in --pxe-service: in
situations where the basename contains a ".", the ".<layer>" suffix is
erroneously added, and in situations where the basename doesn't contain
a ".", the ".<layer>" suffix is erroneously omitted.
A patch against the git HEAD is attached that inverts this logic and
restores the expected behaviour of --pxe-service.
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 was causing confusion: DNSSEC queries would be sent to
servers for domains that don't do DNSSEC, but because of that status
the answers would be treated as answers to ordinary queries,
sometimes resulting in a crash.
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.
Dnsmasq's startup script seems to assume users always want to use
dnsmasq as local DNS resolver, and tells resolvconf to put
"nameserver 127.0.0.1" in /etc/resolv.conf
The problem with this is that if users just want to use dnsmasq
as DHCP server, and put port=0 in /etc/dnsmasq.conf to disable
the DNS functionality, they end up with broken name resolving.
Put a basic check in the startup script that skips resolvconf
configuration if a line starting with port=0 is in /etc/dnsmasq.conf
This doesn't cover all cases (e.g. configuration could also be in
different file in /etc/dnsmasq.d), but is better than current
situation.
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.
The current --server syntax allows for binding to interface or
address. However, in some (admittedly special) cases it is useful to
be able to specify both. This commit introduces the following syntax
to support binding to both interface and address:
--server X.X.X.X@IP@interface#port
Based on my tests, the syntax is backwards compatible with the current
@IP/interface#port. The code will fail if two interface names are given.

The man page says that we don't do DNSSEC on forwarded domains, but if
you turn on dnssec_check_signatures this turns out to be untrue,
because we try to build up a DS chain to them. Since forwarded domains
are usually used for split DNS to hidden domains, they're unlikely to
verify to the DNS root anyway, so the way to do DNSSEC for them (as the
manual says) is to provide a trust anchor for each forwarder.
The problem I've run into is a split DNS setup where I want DNSSEC to
work mostly, but one of the forwarding domains doesn't have an internal
DNSSEC capable resolver. Without this patch the entire domain goes
unresolvable because the DS record query to the internal resolver
returns a failure which is interpreted as the domain being BOGUS.
The fix is not to do the DS record chase for forwarded domains.
