Refactors our use of `slogtest` to instantiate a "standard logger" across most of our tests. This standard logger incorporates https://github.com/coder/slog/pull/217 to also ignore database query canceled errors by default, which are a source of low-severity flakes.
Any test that has set non-default `slogtest.Options` is left alone. In particular, `coderdtest` defaults to ignoring all errors. We might consider revisiting that decision now that we have better tools to target the really common flaky Error logs on shutdown.
closes#14730
Adds support for WorkspaceUpdates to the WebsocketDialer. This allows us to dial the new endpoint added in #14847 and connect it up to a `tailnet.Controllers` to connect to all agents over the tailnet.
I refactored the fakeWorkspaceUpdatesProvider to a mock and moved it to `tailnettest` so it could be more easily reused. The Mock is a little more full-featured.
chore of #14729
Refactors the `ServerTailnet` to use `tailnet.Controller` so that we reuse logic around reconnection and handling control messages, instead of reimplementing. This unifies our "client" use of the tailscale API across CLI, coderd, and wsproxy.
Drops support for v1 of the tailnet API, which was the original coordination protocol where we only sent node updates, never marked them lost or disconnected.
v2 of the tailnet API went GA for CLI clients in Coder 2.8.0, so clients older than that would stop working.
This adds the ability for `TunnelAuth` to also authorize incoming wireguard node IPs, preventing agents from reporting anything other than their static IP generated from the agent ID.
I noticed a possible race where tailnet.Conn can try to dial the embedded region before we've set our custom dialer that send the DERP in-memory. This closes that race and adds a test case for servertailnet with no STUN and an embedded relay
Fixes an issue where a MultiAgentConn isn't closed properly when the coordinator it is connected to is closed.
Since servertailnet checks whether the conn is closed before reinitializing, it is important that we check this, otherwise servertailnet can get stuck if the coordinator closes (e.g. when we switch from AGPL to PGCoordinator after decoding a license).
Adds support to `ServerTailnet` to set all peers lost before attempting to reconnect to the coordinator. In practice, this only really affects `wsproxy` since coderd has a local connection to the coordinator that only goes down if we're shutting down or change licenses.
This one is huge, and I'm sorry.
The problem is that once I change `tailnet.Conn` to start doing v2 behavior, I kind of have to change it everywhere, including in CoderSDK (CLI), the agent, wsproxy, and ServerTailnet.
There is still a bit more cleanup to do, and I need to add code so that when we lose connection to the Coordinator, we mark all peers as LOST, but that will be in a separate PR since this is big enough!
* chore: add /v2 to import module path
go mod requires semantic versioning with versions greater than 1.x
This was a mechanical update by running:
```
go install github.com/marwan-at-work/mod/cmd/mod@latest
mod upgrade
```
Migrate generated files to import /v2
* Fix gen
* feat: automatically use websockets if DERP upgrade is unavailable
This might be our biggest hangup for deployments at the moment...
Load balancers by default do not support the DERP protocol, so many
of our prospects and customers run into failing workspace connections.
This automatically swaps to use WebSockets, and reports the reason to
coderd.
In a future contribution, a warning will appear by the agent if it was
forced to use WebSockets instead of DERP.
