* Improves separation of concerns between `runDockerInspect` and
`convertDockerInspect`: `runDockerInspect` now just runs the command and
returns the output, while `convertDockerInspect` now does all of the
conversion and parsing logic.
* Improves testing of `convertDockerInspect` using real test fixtures.
* Fixes issue where the container port is returned instead of the host
port.
* Updates UI to link to correct host port. Container port is still
displayed in the button text, but the HostIP:HostPort is shown in a
popover.
* Adds stories for workspace agent UI
This change stes additional env vars. This is useful for programs that
assume their presence (for instance, Zed remote relies on SHELL).
See `man login`.
`devcontainer.metadata` is apparently an array, not an object. Missed
this first time round!

Added an additional SSH listener on port 22, so the agent now listens on both, port one and port 22.

Modify the RSA key generation algorithm to check that GCD(e, p-1) = 1 and
GCD(e, q-1) = 1 when selecting prime numbers, ensuring that e and φ(n)
are coprime. This prevents ModInverse from returning nil, which would
cause private key generation to fail and result in a panic when `Precompute` is called.

Builds on top of https://github.com/coder/coder/pull/16623/ and wires up
the ReconnectingPTY server. This does nothing to wire up the web
terminal yet but the added test demonstrates the functionality working.
Other changes:
* Refactors and moves the `SystemEnvInfo` interface to the
`agent/usershell` package to address follow-up from
https://github.com/coder/coder/pull/16623#discussion_r1967580249
* Marks `usershellinfo.Get` as deprecated. Consumers should use the
`EnvInfoer` interface instead.

The Agent's SSH server now initially generates fixed host keys and, once it receives its manifest, generates and replaces that host key with the one derived from the workspace ID, ensuring consistency across agent restarts. This prevents SSH warnings and host key verification errors when connecting to workspaces through Coder Desktop.
While deterministic keys might seem insecure, the underlying Wireguard tunnel already provides encryption and anti-spoofing protection at the network layer, making this approach acceptable for our use case.

This change adds a new `ReportConnection` endpoint to the `agentapi`.
The protocol version was bumped previously, so it has been omitted here.
This allows the agent to report connection events, for example when the
user connects to the workspace via SSH or VS Code.
Updates #15139
This change refactors the parsing of MagicSessionEnvs in the agentssh
package and moves the logic to an earlier stage. Also intoduces enums
for MagicSessionType.
Refs #15139
As part of the new resources monitoring logic - more specifically for
OOM & OOD Notifications , we need to update the AgentAPI , and the
agents logic.
This PR aims to do it, and more specifically :
We are updating the AgentAPI & TailnetAPI to version 24 to add two new
methods in the AgentAPI :
- One method to fetch the resources monitoring configuration
- One method to push the datapoints for the resources monitoring.
Also, this PR adds a new logic on the agent side, with a routine running
and ticking - fetching the resources usage each time , but also storing
it in a FIFO like queue.
Finally, this PR fixes a problem we had with RBAC logic on the resources
monitoring model, applying the same logic than we have for similar
entities.
Fixes https://github.com/coder/coder/issues/16268
- Adds `/api/v2/workspaceagents/:id/containers` coderd endpoint that allows listing containers
visible to the agent. Optional filtering by labels is supported.
- Adds go tools to the `coder-dylib` CI step so we can generate mocks if needed
Relates to https://github.com/coder/internal/issues/329
It's currently unclear where the SIGHUP came from; adding some logging
to make it more clear if it happens again in future.

Replace Depot build action with Nix for Nix dogfood image builds
The dogfood Nix image is now built using Nix's native container tooling instead of Depot. This change:
- Adds Nix setup steps to the GitHub Actions workflow
- Removes the Dockerfile.nix in favor of a Nix-native container build
- Updates the flake.nix to support building Docker images
- Introduces a hash file to track Nix-related changes
- Updates the vendorHash for Go dependencies

- Adds `testutil.GoleakOptions` and consolidates existing options to
this location
- Pre-emptively adds required ignore for this Dependabot PR to pass CI
https://github.com/coder/coder/pull/16066
Second step to resolve [open_in
issue](https://github.com/coder/terraform-provider-coder/issues/297)
This PR improves the way the open_in parameter is forwarded across the
code, changing the last `string` to const everywhere.
Also make sure it is available and forwarded up to the `CreateLink`
component.
- Filters env vars specific to agent-exec from the exec'd process. This
is to prevent any issues when developing Coder in Coder, particularly
agent tests in the cli pkg.
- Fixes an issue where oom scores would fail to be adjusted in cases
where the `coder` binary has capabilities set on it. This is because
`PR_SET_DUMPABLE` is set to `0` when a process is executed with elevated
capabilities. The fix is to flip `PR_SET_DUMPABLE` to `1` prior to
writing to `oom_score_adj`.
- Integrates the `agentexec` pkg into the agent and removes the
legacy system of iterating over the process tree. It adds some linting
rules to hopefully catch future improper uses of `exec.Command` in the package.

Fixes an issue where two goroutines were sharing the `err` variable, leading to a data race where we'd fail to process the error and then nil-pointer panic.
I ended up refactoring reconnecting PTY stuff into the `reconnectingpty` package, instead of having it on the agent. That `createTailnet` routine had waaay too many deeply nested goroutines, which is I'm sure a big contributor to the bug appearing in the first place.
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.
Fixes https://github.com/coder/internal/issues/214#15475 missed that we also write to `rpty` after starting
`rpty.lifecycle()`.
This PR moves the function call right at the end. Hopefully this should
address the data races before we go resorting to mutexes.
Bumps the Tailnet and Agent API version 2.3, and creates some extra controls and machinery around these versions.
What happened is that we accidentally shipped two new API features without bumping the version. `ScriptCompleted` on the Agent API in Coder v2.16 and `RefreshResumeToken` on the Tailnet API in Coder v2.15.
Since we can't easily retroactively bump the versions, we'll roll these changes into API version 2.3 along with the new WorkspaceUpdates RPC, which hasn't been released yet. That means there is some ambiguity in Coder v2.15-v2.17 about exactly what methods are supported on the Tailnet and Agent APIs. This isn't great, but hasn't caused us major issues because
1. RefreshResumeToken is considered optional, and clients just log and move on if the RPC isn't supported.
2. Agents basically never get started talking to a Coderd that is older than they are, since the agent binary is normally downloaded from Coderd at workspace start.
Still it's good to get things squared away in terms of versions for SDK users and possible edge cases around client and server versions.
To mitigate against this thing happening again, this PR also:
1. adds a CODEOWNERS for the API proto packages, so I'll review changes
2. defines interface types for different API versions, and has the agent explicitly use a specific version. That way, if you add a new method, and try to use it in the agent without thinking explicitly about versions, it won't compile.
With the protocol controllers stuff, we've sort of already abstracted the Tailnet API such that the interface type strategy won't work, but I'll work on getting the Controller to be version aware, such that it can check the API version it's getting against the controllers it has -- in a later PR.
Fixes https://github.com/coder/coder/issues/12687
There was a race condition where we would start the rpty lifecycle
before generating the ID, leading to a data race where we would try to
concurrently read and write the struct field.
Closes#14729
Expands the Coordination controller used by the CLI client to allow multiple tunnel destinations (agents). Our current client uses just one, but this unifies the logic so that when we add Coder VPN, 1 is just a special case of "many."
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
fixes#14715
Configures agents to use an address both in the Tailscale service prefix and the new Coder service prefix. Also modifies the Coordinator auth to allow the new prefix.
Updates `coder/tailscale` to include https://github.com/coder/tailscale/pull/62 which fixes a bug around forwarding TCP connections to localhost. This functionality is tested in the modifications to `TestAgent_Dial`.
