'add_local_hostname' previous implementation may drop some addresses.
Soft addition of IP6 addresses may not cause a reload or restart event.
dnsmasq '--interface-name' robustly applies DNS to all addresses per
interface (except fe80::/10).
Change UCI 'add_local_hostname' to expand during each interface assignement
during add_dhcp().
Assign '<iface>.<host>.<domain>' as true name (reflexive A, AAAA, and PTR).
Assign '<host>.<domain>' and '<host>' as convinience aliases (no PTR, not
technically CNAME).
This is accomplished with the '--interface-name' order, first is PTR.
We could also assign each <ip4/6>.<iface>.<host>.<domain> to the respective
dual stack on the interface.
That seemed excessive so it was skipped (/4 or /6 suffix to the interface).
Add UCI 'add_wan_hostname' similar to 'add_local_hostname' function for
external WAN.
WAN IP4 are less often named by the ISP and rarely WAN IP6 due to complexity.
For logs, LuCI connection graph, and other uses assigning a WAN name is desired.
'add_local_hostname' only applies with DHCP and 'add_wam_hostname' only applies
without DHCP. Common residential users will want to set both options TRUE.
Businesses will probably have global DNS, static IP, and 'add_wan_hostname' FALSE.

Correct splitting the 32-bit 'hostid' value to two 16-bit hexadecimal
values. Previously, the lower 16-bit value was truncated to an 8-bit
value, which would result in hostid values 100 and 200 both to be set
to [::0:0] instead of [::0:100] and [::0:200] respectively.

Adds the mac address of the DNS requestor to DNS queries which
are forwarded upstream and can be used to do filtering by the
upstream servers. This only works if the requestor is on the
same subnet as the dnsmasq server
The addmac parameter can hold the following values:
0 : mac address is not added
1 : mac address is added in binary format
base64 : mac address is added base64 encoded
text: : mac address is added in human readable format
as hex and colons

Adds support in uci for configuring multiple dnsmasq instances via
multiple dnsmasq sections.
The uci sections host, boot, mac, tag, vendorclass, userclass,
circuitid, ... will refer to a dnsmasq instance via the instance
parameter defined in the section; if the instance parameter is
not specified backwards compatibility is preserved.
Start/Stopping a dnsmasq instance can be achieved by passing the
dnsmasq instance name as argument to start/stop via the init script.
Multiple dnsmasq instances is usefull in scenarios where you want to
bind a dnsmasq instance to an interface in order to isolate networks.
This patch is a rework of a multiple dnsmasq instance patch by Daniel Dickinson

The force option will convert the dhcp-option to force-dhcp-option if set to 1 in

Regression introduced by 3481d0d dnsmasq: run as dedicated UID/GID
dnsmasq is unable to remove its own pidfile as /var/run/dnsmasq is owned
by root and now dnsmasq runs as dnsmasq:dnsmasq. Change directory
ownership to match.
dnsmasq initially starts as root, creates the pidfile, then drops to
requested non-root user. Until this fix dnsmasq had insufficient
privilege to remove its own pidfile.

multiple invocation of dnsmasq script (e.g. by procd and hotplugd)

Change dnsmasq's dnssec time check handling to use time validity
indicated by ntpd rather than maintaining a cross boot/upgrade
/etc/dnsmasq.time timestamp file. This saves flash device wear.
If ntpd client is configured in uci and you're using dnssec, then
dnsmasq will not check dnssec timestamp validity until ntpd hotplug
indicates sync via a stratum change. The ntpd hotplug leaves a status
flag file to indicate to dnsmasq.init that time is valid and that it
should now start in 'check dnssec timestamp valid' mode.
If ntpd client is not configured and you're using dnssec, then it is
presumed you're using an alternate time sync mechanism and that time is
correct, thus dnsmasq checks dnssec timestamps are valid from 1st start.
Signed-off-by: Kevin Darbyshire-Bryant <kevin@darbyshire-bryant.me.uk>
V2 - stratum & step ntp changes indicate time is valid
V3 - on initial flag file step signal dnsmasq with SIGHUP if running
V4 - only accept step ntp changes. Accepting both stratum & step could
result in unpleasant script race conditions
V5 - Actually only accepting stratum is the correct thing to do after
further testing
V6 - improve handling of non busybox ntpd
if sysntpd not executable
dnsmasq checks dnssec timestamps
else
sysntp script disabled - look for timestamp file - allows external mechanism to use hotplug flag file
sysntp script enabled & uci ntp enabled - look for timestamp file
sysntp script enabled & uci ntp disabled - dnsmasq checks dnssec
timestamps

Add support for hostid dhcp config entry to dnsmasq. This allows
specification of dhcpv6 hostid suffix and works in the same way as
odhcpd.
Entries in auto generated dnsmasq.conf should conform to:
dhcp-host=mm:mm:mm:mm:mm:mm,IPv4addr,[::V6su:ffix],hostname
example based on sample config/dhcp entry:
config host
option name 'Kermit'
option mac 'E0:3F:49:A1:D4:AA'
option ip '192.168.235.4'
option hostid '4'
dhcp-host=E0:3F:49:A1:D4:AA,192.168.235.4,[::0:4],Kermit

conditionally save dnsmasq.time across sysupgrade
dnsmasq uses /etc/dnsmasq.time as record of the last known good
system time to aid its validation of dnssec timestamps. dnsmasq
updates the timestamp on process start/stop once it considers the system
time as valid. The timestamp file should be preserved across system
upgrade but should not be included as part of normal configuration
backups to prevent restores corrupting the current timestamp.

Enable setting a host-specific lease time for static hosts.
The new option is called "leasetime" and the format is similar
as for the default lease time: e.g. 12h, 3d, infinite
Default lease time is used for all hosts for which there is
no host-specific definition.
The option is added to /etc/config/dhcp for the selected hosts:
config host
option name 'Nexus'
option mac 'd8:50:66:55:59:7c'
option ip '192.168.1.245'
option leasetime '2h'
It gets appended to /var/etc/dnsmasq.conf like this:
dhcp-host=d8:50:66:55:59:7c,192.168.1.245,Nexus,2h

Commit 6a7e56b adds support for adding local hostname for own lan ula adress
but if ula prefix is not specified results into an invalid config (address=/OpenWrt.lan/1)
causing dnsmasq not to start up.
Use lanaddr6 when adding local hostname as the lan ula address is constructed based on the
UCI parameters ip6hint and ip6ifaceid and thus not always ula prefix suffixed with 1

Changed option nonwildcard from --bind-interfaces into --bind-dynamic.
With this, Dnsmasq binds the address of individual interfaces, allowing multiple
dnsmasq instances, but if new interfaces or addresses appear, it automatically
listens on those. This makes dynamically created interfaces work in the same way as
the default, but allows also use of other DNS-servers (like Named) at the same time
on diffirent interfaces where Dnsmasq is NOT configured, whereas with
--bind-interfaces will still reserve every interface even if not used and thus
disallowing use of any other DNS-program even on unused interfaces.
