This PR showcases the implementation of additional linter rules. I've updated the golangci-lint GitHub Actions to the latest available version. This update makes sure that the tool works the same way locally - assuming being updated regularly - and with the GitHub Actions.
I've also taken care of keeping all the GitHub Actions up to date, which helps our code stay current. But there's one part, goreleaser that's a bit tricky to test on our computers. So, it's important to take a close look at that.
To make it easier to understand what I've done, I've made separate changes for each thing that the new linters found. This should help the people reviewing the changes see what's going on more clearly. Some of the changes might not be obvious at first glance.
Things to consider for the future
CI runs on Ubuntu so the static analysis only happens for Linux. Consider running it for the rest: Darwin, Windows
* Add DNS list argument for mobile client
* Write testable code
Many places are checked the wgInterface != nil condition.
It is doing it just because to avoid the real wgInterface creation for tests.
Instead of this involve a wgInterface interface what is moc-able.
* Refactor the DNS server internal code structure
With the fake resolver has been involved several
if-else statement and generated some unused
variables to distinguish the listener and fake
resolver solutions at running time. With this
commit the fake resolver and listener based
solution has been moved into two separated
structure. Name of this layer is the 'service'.
With this modification the unit test looks
simpler and open the option to add new logic for
the permanent DNS service usage for mobile
systems.
* Remove is running check in test
We can not ensure the state well so remove this
check. The test will fail if the server is not
running well.
Works only with userspace implementation:
1. Configure host to solve DNS requests via a fake DSN server address in the Netbird network.
2. Add to firewall catch rule for these DNS requests.
3. Resolve these DNS requests and respond by writing directly to wireguard device.
Add new feature to notify the user when new client route has arrived.
Refactor the initial route handling. I move every route logic into the route
manager package.
* Add notification management for client rules
* Export the route notification for Android
* Compare the notification based on network range instead of id.
This PR adds supports for the WireGuard userspace implementation
using Bind interface from wireguard-go.
The newly introduced ICEBind struct implements Bind with UDPMux-based
structs from pion/ice to handle hole punching using ICE.
The core implementation was taken from StdBind of wireguard-go.
The result is a single WireGuard port that is used for host and server reflexive candidates.
Relay candidates are still handled separately and will be integrated in the following PRs.
ICEBind checks the incoming packets for being STUN or WireGuard ones
and routes them to UDPMux (to handle hole punching) or to WireGuard respectively.
* Disable upstream DNS resolver after several tries and fails
* Add tests for upstream fails
* Use an extra flag to disable domains in DNS upstreams
* Fix hashing IPs of nameservers for updates.
Adding --external-ip-map and --dns-resolver-address to up command and shorthand option to global flags.
Refactor get and read config functions with new ConfigInput type.
updated cobra package to latest release.
Added host configurators for Linux, Windows, and macOS.
The host configurator will update the peer system configuration
directing DNS queries according to its capabilities.
Some Linux distributions don't support split (match) DNS or custom ports,
and that will be reported to our management system in another PR
Added DNS update protocol message
Added sync to clients
Update nameserver API with new fields
Added default NS groups
Added new dns-name flag for the management service append to peer DNS label
