2336b942b3 dnsmasq: don't use network functions at boottime (FS#1542)
As dnsmasq is started earlier than netifd usage of network.sh functions
at boottime will fail; therefore don't call at boottime the functions
which construct the dhcp pool/relay info.
As interface triggers are installed the dhcp pool/relay info will be
constructed when the interface gets reported as up by netifd.
At the same time also register interface triggers based on DHCP relay
config.

0e84393ee2 dnsmasq: fix dnsmasq startup issue
Commit ecd954d530 installs specific interface triggers which rewrites the dnsmasq config
file and restarts dnsmasq if the network interface becomes active for which a trigger
has been installed.
In case no dhcp sections are specified or ignore is set to 1 dnsmasq will not be started
at startup which breaks DNS resolving.
Fix this by ditching the BOOT check in start_service and always start dnsmasq at startup.

ecd954d530 dnsmasq: add specific interface procd triggers
Right now interface.update events are sent out by netifd upon interface state,
route, address (lifetime), prefix lifetime changes.
Dnsmasq is only interested in interface state changes and currently adds an
interface trigger for all the "interface.*" events.
In combination with commit 23bba9cb33, which triggers a SIGHUP signal to dnsmasq,
IPv6 address/prefix lifetime changes on the wan will trigger dnsmasq reloads which
can become frequent in case of shorter lifetimes.

To avoid frequent dnsmasq reload, this patch adds specific interface triggers.
During dnsmasq init it loops dhcp uci section; if the value of the ignore option
is set to 0, then the corresponding interface trigger is not installed.
Otherwise, if the ignore option value is 1, then procd_add_interface_trigger is
called which adds the interface trigger.

7ffb707576 dnsmasq: add listen_address parameter
This patch adds a parser for the uci representation of
dnsmasq's "-a | --listen-address" option.

In summary, this option forces dnsmasq to listen on the
given IP address(es). Both interface and listen-address
options may be given, in which case the set of both
interfaces and addresses is used.

Note that if no interface option is given, but listen_address is,
dnsmasq will not automatically listen on the loopback interface.
To achieve this, the loopback IP addresses, 127.0.0.1 and/or ::1
must be explicitly added.

This option is useful for ujailed dnsmasq instances, that would
otherwise fail to work properly, because listening to the
"This host on this network" address (aka 0.0.0.0 see rfc1700 page 4)
may not be allowed.

feab5fa51e dnsmasq: fix dhcp "ignore" option on wwan interfaces
Init script won't append --no-dhcp-interface option if interface
protocol is one of: ncm, directip, qmi, mbim.
This is caused by IP address assigned to dynamically created netifd
interfaces. As a result there's no netmask assigned to the main
interface and dhcp_add() function returns prematurely.

By moving network subnet check we can ensure that --no-dhcp-interface is
properly generated for wwan interfaces.

Quoting dnsmasq's author "bind-dynamic (bind individual addresses, keep
up with changes in interface config) ... On linux, there's actually no
sane reason not to use --bind-dynamic, and it's only not the default for
historical reasons."

3a06dd60eb dnsmasq: do not forward rfc6761 excluded domains
RFC 6761 defines a number of top level domains should not be forwarded
to the Internet's domain servers since they are not responsible for
those domains.

This change adds a list of domains that will be blocked when 'boguspriv'
is used and augments that which is already blocked by dnsmasq's notion
of 'local service' using '--bogus-priv' i.e. RFC 1918 private addresses
and IPv6 prefixes as defined in RFC 6303.

To make this configurable rather than hard coded in dnsmasq's init
script, a new file /usr/share/dnsmasq/rfc6761.conf is conditionally
included.

The default file matches the RFC 6761 recommendation along with a few
other top level domains that should not be forwarded to the Internet.

9525743c07 dnsmasq: make DHCPv6 viable for standalone dnsmasq install
dnsmasq has sufficient services to meet the needs of DHCP
and RA with IP6 for single router router users. This is
the most common use for consumer routers. Its reenforced
as most ISP tend to only DHCP-PD /64. dnsmasq has year
over year demonstrated great flexibility in its option
set, and support for off-standard DHCP clients.

odhcpd has enhanced capabilities focused on IP6 such
as DHCP/RA relay and NDP proxy. However, it is not as
flexible in its option set. odhcpd is not as forgiving
with off-standard DHCP clients. Some points may represent
a long term TODO list, but it is the state currently.

These changes make any such combination possible. Already
odhcpd can be set as the main dhcp server. Now odhcpd
can be removed or disabled and dnsmasq will take over
if DHCPv6 compiled in. The existing DHCPv6 and RA UCI
are translated into dnsmasq.conf. The changes focus on
'--dhcp-range', '--dhcp-host', and '--dhcp-options'.

DHCP host ID is least 16 bits [::1000-::FFFF], but
leaves low range for typical infrastructure assignments.
dnsmasq accepts DHCPv6 options in the tranditional
'--dhcp-option' put they must be prefixed 'option6:'.
dnsmasq will also discover SLAAC DNS entries from DHCPv4
clients MAC, and confirm with a ping at least renew.

Long term TODO include improving use of dnsmasq relay
options for DHCPv4 and DHCPv6 in parallel. It would also
be possible to preconfigure DHCP-PD in host-with-options
records for fixed infrastructure.

1b4e3eda1b dnsmasq: expand 'add_local_hostname' fexibility including FQDN
ref commit 612e2276b4
ref commit ec63e3bf13

'option add_local_hostname' scripted implementation statically assigns
this host in auto generated host file at init. If IFUP or other signals
do not occur, then address changes are not tracked. The script doesn't
apply all the addresses at an interface. This may make logs obscure.
The script only puts the bare host name (maybe not FQDN) in host file,
but if '--exapandhosts' is enabled, then /etc/hosts entries will be
suffixed, and "127.0.0.1 localhost" becomes "localhost.lan".

dnsmasq provides an option to perform this function, but it is rather
greedy. '--interface-name=<name>,<iface>' will assign the name to all
IP on the specified interface (except link local). This is a useful
feature, but some setups depend on the original restrictive behavior.

'option add_local_fqdn' is added to enhance the feature set, but
if not entered or empty string, then it will default to original
option and behavior. This new option has a few settings. At each
increased setting the most detailed name becomes the PTR record:
0 - same as add_local_hostname 0 or disabled
1 - same as add_local_hostname 1
2 - assigns the bare host name to all IP w/ --dnsmasq-interface
3 - assigns the FQDN and host to all IP w/ --dnsmasq-interface
4 - assigns <iface>.<host>.<domain> and above w/ --dnsmasq-nterface

'option add_wan_fqdn' is added to run the same procedure on
inferred WAN intefaces. If an interface has 'config dhcp' and
'option ignore 1' set, then it is considered WAN. The original
option would only run on DHCP serving interfaces.

ec63e3bf13 Revert "dnsmasq: change 'add_local_hostname' to use dnsmasq '--interface-name'"
This causes problem when a FQDN is configured in /etc/config/system. The
domain name will appear twice in reverse DNS.

Next to that, there seems to be a bug in dnsmasq. From the manual page:

--interface-name=<name>,<interface>[/4|/6]
Return  a  DNS  record  associating  the  name  with  the primary address
on the given interface. This flag specifies an A or AAAA record for the
given name in the same way as an /etc/hosts line, except that the address
is not constant, but taken from the given interface. The interface may be
followed by "/4" or "/6" to specify  that  only  IPv4  or  IPv6 addresses
of the interface should be used. If the interface is down, not configured
or non-existent, an empty record is returned. The matching PTR record is
also created, mapping the interface address to the name. More than one name
may be associated with an interface address by repeating the flag; in that
case the first instance is used for  the  reverse address-to-name mapping.

It does not just create an A/AAAA record for the primary address, it creates
one for all addresses. And what is worse, it seems to actually resolve to the
non-primary address first. This is quite annoying when you use floating IP
addresses (e.g. VRRP), because when the floating IP is on the other device,
SSH failes due to incorrect entry in the known hosts file.

I know that this is not a common setup, but it would be nice if there was an
option to restore the previous behaviour, rather than just forcing this new
feature on everybody.

612e2276b4 dnsmasq: change 'add_local_hostname' to use dnsmasq '--interface-name'
'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.
