On some platforms, like pfsense, ntpd is not problem, so do not spawn
the DNS server for it, which may conflict with default DNS server.
While at it, also make sure that ctrld will be run at last on startup.
On DD-WRT v3.0-r52189, dnsmasq version 2.89 lease format looks like:
1685794060 <mac> <ip> <hostname> 00:00:00:00:00:04 9
It has 6 fields, while the current parser only looks for line with exact
5 fields, which is too restricted. In fact, the parser shold just skip
line with less than 4 fields, because the 4th field is the hostname,
which is the last client info that ctrld needs.
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.
The assignment is changed wrongly in process of refactoring parallel
dialer for resolving bootstrap IP.
While at it, also satisfy staticheck for jffs not enabled error.
On some Merlin routers, the time is broken when system reboot, and need
to wait for NTP synced to get the correct time. For fetching API in cd
mode successfully, ctrld need to wait until NTP set the time correctly,
otherwise, the certificate validation would complain.
On some Merlin routers, due to ntp bug, after rebooing, dnsmasq config
was restored to default without ctrld changes, causing ctrld stop
working. Workaround this problem by catching restart diskmon event,
which is triggered by ntpd_synced, then restart dnsmasq.
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.
