available in the standard library since Go 1.21.

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.

Fixes: https://github.com/coder/coder/issues/16490
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 refactors the parsing of MagicSessionEnvs in the agentssh
package and moves the logic to an earlier stage. Also intoduces enums
for MagicSessionType.
Refs #15139
- 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
- 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.
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.
This commit refactors where custom environment variables are set in the
workspace and decouples agent specific configs from the `agentssh.Server`.
To reproduce all functionality, `agentssh.Config` is introduced.
The custom environment variables are now configured in `agent/agent.go`
and the agent retains control of the final state. This will allow for
easier extension in the future and keep other modules decoupled.
* chore: check if process is nil
We check if process is nil in the ports_supported file.
Just matching that defensive check, not sure if it can be nil.
Fixes#10799
The flake happens when we try to remote forward, but the port we've chosen is not free. In the flaked example, it's actually the SSH listener that occupies the port we try to remote forward, leading to confusing reads (c.f. the linked issue).
This fix simplies the tests considerably by using the Go ssh client, rather than shelling out to OpenSSH. This avoids using a pseudoterminal, avoids the need for starting any local OS listeners to communicate the forwarding (go SSH just returns in-process listeners), and avoids an OS listener to wire OpenSSH up to the agentConn.
With the simplied logic, we can immediately tell if a remote forward on a random port fails, so we can do this in a loop until success or timeout.
I've also simplified and fixed up the other forwarding tests. Since we set up forwarding in-process with Go ssh, we can remove a lot of the `require.Eventually` logic.
Fixes an issue where remote forwards are not correctly torn down when using OpenSSH with `coder ssh --stdio`. OpenSSH sends a disconnect signal, but then also sends SIGHUP to `coder`. Previously, we just exited when we got SIGHUP, and this raced against properly disconnecting.

* 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
