So setting up logging for ctrld binary and ctrld packages could be done
more easily, decouple the required setup for interactive vs daemon
running.
This is the first step toward replacing rs/zerolog libary with a
different logging library.
So using "ctrld stop" or service manager to stop ctrld will end up with
the same result, stopped ctrld with a working DNS, and deactivation pin
code will always have effects if set.
For partial init log data (does not end with a newline), the log writer
discard data after the last newline to make the log prettier, then write
the init end marker. This causes the marker could be written more than
once, since the second overflows will preserve the data which does
include the marker from the first write.
To fix this, ensure that the init end marker is only written once, and
the second overflows will preserve data until the marker instead of the
fixed initial size like the first one.
smol tweaks to nameserver test queries
fix restoreDNS errors
add some debugging information
fix wront type in log msg
set send logs command timeout to 5 mins
when the runningIface is no longer up, attempt to find a new interface
prefer default route, ignore non physical interfaces
prefer default route, ignore non physical interfaces
add max context timeout on performLeakingQuery with more debug logs
Since ctrld process does not rely on the global variable iface anymore
during runtime, ctrld client's operations must be updated to reflect
this change, too.
By attempting to reset DNS before starting new ctrld process. This way,
ctrld will read the correct system DNS settings before changing itself.
While at it, some optimizations are made:
- "ctrld start" won't set DNS anymore, since "ctrld run" has already did
this, start command could just query socket control server and emittin
proper message to users.
- The gateway won't be included as nameservers on Windows anymore,
since the GetAdaptersAddresses Windows API always returns the correct
DNS servers of the interfaces.
- The nameservers list that OS resolver is using will be shown during
ctrld startup, making it easier for debugging.
