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.
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!
wsproxy also needs to be updated to use tailnet v2 because the `tailnet.Conn` stores peers by ID, and the peerID was not being carried by the JSON protocol. This adds a query param to the endpoint to conditionally switch to the new protocol.
Due to a logical error in CommitQuota, all workspace Stop->Start operations
were being accepted, regardless of the Quota limit. This issue only
appeared after #9201, so this was a minor regression in main for about
3 days. This PR adds a test to make sure this kind of bug doesn't recur.
To make the new test possible, we give the echo provisioner the ability
to simulate responses to specific transitions.
* 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
