#21926: dnsmasq multiple local domains support (patch)
-----------------------+------------------------

-----------------------+------------------------
The configuration of dnsmasq through uci on OpenWRT (15.05, r46767) does
not support multiple local domains. Although dnsmasqs manpage does
explicitely state:
'''-s, --domain=<domain>[,<address range>[,local]]'''
Specifies DNS domains for the DHCP server. [...]
Which is undeniably pluralized.
The following patch corrects this shortcooming:
{{{
# diff dnsmasq /etc/init.d/dnsmasq
80a81,84
> append_domain() {
> xappend "--domain=$1"
> }
>
146c150
< append_parm "$cfg" "domain" "--domain"
---
> config_list_foreach "$cfg" "domain" append_domain
}}}
'''Result:'''
Configuration (/etc/config/dhcp) changed like this:
{{{
config dnsmasq
[...]
list domain
'dmz.home.example.com,192.168.1.0/24,local'
list domain
'home.example.com,192.168.10.0/24,local'
list domain
'dev.home.example.com,192.168.12.0/24,local'
[...]
}}}
Result (/var/etc/dnsmasq.conf):
{{{
domain=dmz.home.example.com,192.168.1.0/24,local
domain=home.home.example.com,192.168.10.0/24,local
domain=dev.home.example.com,192.168.12.0/24,local
}}}
This does correctly resolve all hosts to the correct subdomains by
specifing them inside the network, i.e.:
{{{
config host
option ip '192.168.1.1'
option mac 'aa:bb:cc:dd:ee:f0'
option name 'gw'
}}}
Resolves ''gw.dmz.home.example.com'' to ''192.168.1.1'' and vice versa.
{{{
config host
option ip '192.168.10.10'
option mac 'aa:bb:cc:dd:ee:f1'
option name 'ozzy'
}}}
Resolves''ozzy.home.example.com'' to ''129.168.10.10'' and vice versa.
{{{
config host
option ip '192.168.12.10'
option mac 'aa:bb:cc:dd:ee:f2'
option name 'lemmy'
}}}
Resolves ''lemmy.dev.home.example.com'' to ''192.168.12.10'' and vice
versa.
