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.
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.
Refactors the way clients of the Tailnet API (clients of the API, which include both workspace "agents" and "clients") interact with the API. Introduces the idea of abstract "controllers" for each of the RPCs in the API, and implements a Coordination controller by refactoring from `workspacesdk`.
chore re: #14729
Closes#14716Closes#14717
Adds a new user-scoped tailnet API endpoint (`api/v2/tailnet`) with a new RPC stream for receiving updates on workspaces owned by a specific user, as defined in #14716.
When a stream is started, the `WorkspaceUpdatesProvider` will begin listening on the user-scoped pubsub events implemented in #14964. When a relevant event type is seen (such as a workspace state transition), the provider will query the DB for all the workspaces (and agents) owned by the user. This gets compared against the result of the previous query to produce a set of workspace updates.
Workspace updates can be requested for any user ID, however only workspaces the authorised user is permitted to `ActionRead` will have their updates streamed.
Opening a tunnel to an agent requires that the user can perform `ActionSSH` against the workspace containing it.
re: #14715
This PR introduces the Coder service prefix: `fd60:627a:a42b::/48` and refactors our existing code as calling the Tailscale service prefix explicitly (rather than implicitly).
Removes the unused `Addresses` agent option. All clients today assume they can compute the Agent's IP address based on its UUID, so an agent started with a custom address would break things.
Fixes#12560
When gracefully disconnecting from the coordinator, we would send the Disconnect message and then close the dRPC stream. However, closing the dRPC stream can cause the server not to process the Disconnect message, since we use the stream context in a `select` while sending it to the coordinator.
This is a product bug uncovered by the flake, and probably results in us failing graceful disconnect some minority of the time.
Instead, the `remoteCoordination` (and `inMemoryCoordination` for consistency) should send the Disconnect message and then wait for the coordinator to hang up (on some graceful disconnect timer, in the form of a context).
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.
Removes the support for the Agent's "legacy IP" which was a hardcoded IP address all agents used to use, before we introduced "single tailnet". Single tailnet went GA in 2.7.0.
When an agent receives a node, it responds with an ACK which is relayed
to the client. After the client receives the ACK, it's allowed to begin
pinging.
Currently, importing `codersdk` just to interact with the API requires
importing tailscale, which causes builds to fail unless manually using
our fork.
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.
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 logging to yamux when used for tailnet client connections, e.g. CLI and wsproxy. This could be useful for debugging connection issues with tailnet v2 API.
fixes#10531
Adds a check for `version` on connection to the Agent API websocket endpoint. This is primarily for future-proofing, so that up-level agents get a sensible error if they connect to a back-level Coderd.
It also refactors the location of the `CurrentVersion` variables, to be part of the `proto` packages, since the versions refer to the APIs defined therein.
Adds support to Coordination to call SetAllPeersLost() when it is closed. This ensure that when we disconnect from a Coordinator, we set all peers lost.
This covers CoderSDK (CLI client) and Agent. Next PR will cover MultiAgent (notably, `wsproxy`).
* 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
```
