Currently, on routers that require NTP waiting, ctrld makes the cleanup
process, and restart dnsmasq for restoring default DNS config, so ntpd
can query the NTP servers. It did work, but the code will depends on
router platforms.
Instead, we can spawn a plain DNS listener before PreRun on routers,
this listener will serve NTP dns queries and once ntp is configured, the
listener is terminated and ctrld will start serving using its configured
upstreams.
While at it, also fix the userHomeDir function on freshtomato, which
must return the binary directory for routers that requires JFFS.
This commit add the ability for ctrld to gather client information,
including mac/ip/hostname, and send to Control-D server through a
config per upstream.
- Add send_client_info upstream config.
- Read/Watch dnsmasq leases files on supported platforms.
- Add corresponding client info to DoH query header
All of these only apply for Control-D upstream, though.
