Cuong Manh LeandCuong Manh Le b82ad3720c cmd/cli: guard against nil client info 
Though it's only possible raised in testing, still better to be safe.

Cuong Manh LeandCuong Manh Le 8d2cb6091e cmd/cli: add QUERY/REPLY prefix to proxying log 
So the log in INFO log is aligned, making it easier for human to
monitoring the log, either via console or running "tail" command.

Cuong Manh LeandCuong Manh Le 44484e1231 cmd/cli: add WSAEHOSTUNREACH to network error 
Windows may raise WSAEHOSTUNREACH instead WSAENETUNREACH in case of
network not available when resuming from sleep or switching network, so
checkUpstream is never kicked in for this type of error.

Cuong Manh LeandCuong Manh Le 8db28cb76e cmd/cli: improving logging of proxying action 
INFO level becomes a sensible setting for normal operation that does not
overwhelm. Adding some small details to make DEBUG level more useful.

Cuong Manh LeandCuong Manh Le 5c24acd952 cmd/cli: fix bug causes checkUpstream run only once 
To prevent duplicated running of checkUpstream function at the same
time, upstream monitor uses a boolean to report whether the upstream is
checking. If this boolean is true, then other calls after the first one
will be returned immediately.

However, checkUpstream does not set this boolean to false when it
finishes, thus all future calls to checkUpstream won't be run, causing
the upstream is marked as down forever.

Fixing this by ensuring the boolean is reset once checkUpstream done.
While at it, also guarding all upstream monitor operations with a mutex,
ensuring there's no race condition between marking upstream state.

Cuong Manh LeandCuong Manh Le dfbcb1489d cmd/cli: improving loop guard test 
We see number of failed test in Github Action, mostly on MacOS or
Windows due to the fact that goroutines are scheduled to be run
consequently.

This commit improves the test, ensuring at least 2 goroutines were
started before increasing the counting.

Cuong Manh LeandCuong Manh Le 5897c174d3 all: fix LAN hostname checking condition 
The LAN hostname in question is FQDN, "." suffix must be trimmed before
checking.

While at it, also add tests for LAN/PTR query checking functions.
 2023-12-06 15:33:05 +07:00
Cuong Manh LeandCuong Manh Le f9a3f4c045 Implement new flow for LAN and private PTR resolution 
- Use client info table.
 - If no sufficient data, use gateway/os/defined local upstreams.
 - If no data is returned, use remote upstream

Cuong Manh LeandCuong Manh Le a2cb895cdc cmd/cli: watch changes to /etc/resolv.conf 
On some routers, change to network may trigger re-rendering
/etc/resolv.conf file, causing requests from router itself stop using
ctrld.

Fixing this by watching changes to /etc/resolv.conf, then revert them.

Cuong Manh LeandCuong Manh Le a2116e5eb5 cmd/cli: do not substitute MAC if empty 
Using IPv4 as hostname is enough to distinguish clients.
 2023-11-27 22:19:16 +07:00
Cuong Manh LeandCuong Manh Le 564c9ef712 cmd/cli: use IP as hostname for ipv4 clients only 
For Android devices, when it joins the network, it uses ctrld to resolve
its private DNS once and never reaches ctrld again. For each time, it uses
a different IPv6 address, which causes hundreds/thousands different client
IDs created for the same device, which is pointless.

Cuong Manh LeandCuong Manh Le 856abb71b7 cmd/cli: only notice reading config with "ctrld start" 
While at it, also updating the documentation of related functions.

Cuong Manh LeandCuong Manh Le 4f125cf107 cmd/cli: notice users where config file is written/read 2023-11-16 20:59:12 +07:00
Cuong Manh LeandCuong Manh Le 494d8be777 cmd/cli: skip router setup with "ctrld service start" 
Either do magic stuff and make things work automatically (normal users),
or don't do any of it and just run ctrld as a service (power users).

Cuong Manh LeandCuong Manh Le d01f5c2777 cmd/cli: do not stop listener when reloading 
We could not do a reload if the listener config changes, so do not turn
them off to try updating new listener config.

Cuong Manh LeandCuong Manh Le 09188bedf7 cmd/cli: fix wrong generated config for nextdns resolver 
Generating nextdns config must happen after stopping current ctrld
process. Otherwise, config processing may pick wrong IP+Port.

While at it, also making logging better when updating listener config:

 - Change warn to info, prevent confusing that "something is wrong".
 - Do not emit info when generating working default config, which may
   cause duplicated messages printed.

Cuong Manh LeandCuong Manh Le 990bc620f7 cmd/cli: strip EDNS0_SUBNET for RFC 1918 and loopback address 
Since passing them to upstream is pointless, these cannot be used by
anything on the WAN.
 2023-11-09 00:23:38 +07:00
Cuong Manh LeandCuong Manh Le 4816a09e3a all: use private resolver for private IP address 
These queries could not be resolved by Control D upstreams, so it's
useless and less performance to send them to servers.
 2023-11-08 23:51:18 +07:00
Cuong Manh LeandCuong Manh Le 63f959c951 all: spoof loopback ranges in client info 
Sending them are useless, so using RFC1918 address instead.

Cuong Manh LeandCuong Manh Le d88cf52b4e cmd/cli: always rebootstrap when check upstream 
Otherwise, network changes may not be seen on some platforms, causing
ctrld failed to recover and failing all requests.

While at it, also doing the check DNS in separate goroutine, prevent it
from blocking ctrld from notifying others that it "started". The issue
was seen when ctrld is configured as direct listener, requests are
flooded before ctrld started, causing the healtch process failed.
 2023-11-06 20:01:25 +07:00
Cuong Manh LeandCuong Manh Le 58a00ea24a all: implement reload command 
This commit adds reload command to ctrld for re-fetch new config from
ContorlD API or re-read the current config on disk.

Cuong Manh LeandCuong Manh Le baf836557c cmd/cli: fix wrong checking condition in removeProvTokenFromArgs 
The provision token is only used once, then do not have any effect after
Control D uid is fetched. So making it appears in "ctrld run" command is
useless.
 2023-11-06 20:00:10 +07:00
Cuong Manh LeandCuong Manh Le 904b23eeac cmd/cli: add --proto flag to set upstream type in cd mode 2023-11-06 19:59:52 +07:00
Cuong Manh LeandCuong Manh Le 6aafe445f5 cmd/cli: add nextdns mode 
Adding --nextdns flag to "ctrld start" command for generating ctrld
config with nextdns resolver id, then use nextdns as an upstream.
 2023-11-06 19:59:31 +07:00
Ginder SinghandCuong Manh Le ebd516855b added safe return if error happens during resolver fetch. 2023-11-06 19:58:53 +07:00
Cuong Manh LeandCuong Manh Le df4e04719e cmd/cli: relax service dependency on systemd-networkd-wait-online 
ctrld wants systemd-networkd-wait-online starts before starting itself,
but ctrld should not be blocked waiting for it started.

Cuong Manh LeandCuong Manh Le 2440d922c6 all: add MAC address base policy
