Subject: [PATCH 1/5] Log listening on new interfaces
Log in debug mode listening on interfaces. They can be dynamically
found, include interface number, since it is checked on TCP connections.
Print also addresses found on them.

Subject: [PATCH] Change dhcp_release to use default address when no IP subnet
matches
Currently, dhcp_release will only send a 'fake' release
when the address given is in the same subnet as an IP
on the interface that was given.
This doesn't work in an environment where dnsmasq is
managing leases for remote subnets via a DHCP relay, as
running dhcp_release locally will just cause it to
silently exit without doing anything, leaving the lease
in the database.
Change it to use the default IP on the interface, as the
dnsmasq source code at src/dhcp.c does, if no matching subnet
IP is found, as a fall-back. This fixes an issue we are
seeing in certain Openstack deployments where we are using
dnsmasq to provision baremetal systems in a datacenter.
While using Dbus might have seemed like an obvious solution,
because of our extensive use of network namespaces (which
Dbus doesn't support), this seemed like a better solution
than creating system.d policy files for each dnsmasq we
might spawn and using --enable-dbus=$id in order to isolate
messages to specific dnsmasq instances.

Subject: [PATCH] Fix sometimes missing DNSSEC RRs when DNSSEC validation not
enabled.
Dnsmasq does pass on the do-bit, and return DNSSEC RRs, irrespective
of of having DNSSEC validation compiled in or enabled.
The thing to understand here is that the cache does not store all the
DNSSEC RRs, and dnsmasq doesn't have the (very complex) logic required
to determine the set of DNSSEC RRs required in an answer. Therefore if
the client wants the DNSSEC RRs, the query can not be answered from
the cache. When DNSSEC validation is enabled, any query with the
do-bit set is never answered from the cache, unless the domain is
known not to be signed: the query is always forwarded. This ensures
that the DNSEC RRs are included.
The same thing should be true when DNSSEC validation is not enabled,
but there's a bug in the logic.
line 1666 of src/rfc1035.c looks like this
if ((crecp->flags & (F_HOSTS | F_DHCP | F_CONFIG)) || !do_bit || !(crecp->flags & F_DNSSECOK))
{ ...answer from cache ... }
So local stuff (hosts, DHCP, ) get answered. If the do_bit is not set
then the query is answered, and if the domain is known not to be
signed, the query is answered.
Unfortunately, if DNSSEC validation is not turned on then the
F_DNSSECOK bit is not valid, and it's always zero, so the question
always gets answered from the cache, even when the do-bit is set.
This code should look like that at line 1468, dealing with PTR queries
if ((crecp->flags & (F_HOSTS | F_DHCP | F_CONFIG)) ||
!do_bit ||
(option_bool(OPT_DNSSEC_VALID) && !(crecp->flags & F_DNSSECOK)))
where the F_DNSSECOK bit is only used when validation is enabled.

Subject: [PATCH] Correct range check of dhcp-host prefix
It incorrectly works with 32 bit integer only when counting number of
addresses in range. It works correctly only between prefixlen 96 and
128. Use 64bit shift to work with well with numbers higher than 64.
Fixes commit 79aba0f10ad0157fb4f48afbbcb03f094caff97a error.

Subject: [PATCH] Support prefixed ranges of ipv6 addresses in dhcp-host.
When a request matching the clid or mac address is
recieved the server will iterate over all candidate
addresses until it find's one that is not already
leased to a different clid/iaid and advertise
this address.
Using multiple reservations for a single host makes it
possible to maintain a static leases only configuration
which support network booting systems with UEFI firmware
that request a new address (a new SOLICIT with a new IA_NA
option using a new IAID) for different boot modes, for
instance 'PXE over IPv6', and 'HTTP-Boot over IPv6'. Open
Virtual Machine Firmware (OVMF) and most UEFI firmware
build on the EDK2 code base exhibit this behaviour.

%description
Dnsmasq is lightweight, easy to configure DNS forwarder and DHCP server.
It is designed to provide DNS and, optionally, DHCP, to a small network.
It can serve the names of local machines which are not in the global
DNS. The DHCP server integrates with the DNS server and allows machines
with DHCP-allocated addresses to appear in the DNS with names configured
either in each host or in a central configuration file. Dnsmasq supports
static and dynamic DHCP leases and BOOTP for network booting of diskless
machines.
