Add ReadLog method to headscale integration container for log
inspection. Split SSH check mode tests into CLI and OIDC variants
and add comprehensive test coverage:
- TestSSHOneUserToOneCheckModeCLI: basic check mode with CLI approval
- TestSSHOneUserToOneCheckModeOIDC: check mode with OIDC approval
- TestSSHCheckModeUnapprovedTimeout: rejection on cache expiry
- TestSSHCheckModeCheckPeriodCLI: session expiry and re-auth
- TestSSHCheckModeAutoApprove: auto-approval within check period
- TestSSHCheckModeNegativeCLI: explicit rejection via CLI
Update existing integration tests to use headscale auth register.
Updates #1850
This PR addresses some consistency issues that was introduced or discovered with the nodestore.
nodestore:
Now returns the node that is being put or updated when it is finished. This closes a race condition where when we read it back, we do not necessarily get the node with the given change and it ensures we get all the other updates from that batch write.
auth:
Authentication paths have been unified and simplified. It removes a lot of bad branches and ensures we only do the minimal work.
A comprehensive auth test set has been created so we do not have to run integration tests to validate auth and it has allowed us to generate test cases for all the branches we currently know of.
integration:
added a lot more tooling and checks to validate that nodes reach the expected state when they come up and down. Standardised between the different auth models. A lot of this is to support or detect issues in the changes to nodestore (races) and auth (inconsistencies after login and reaching correct state)
This PR was assisted, particularly tests, by claude code.
This commit restructures the map session in to a struct
holding the state of what is needed during its lifetime.
For streaming sessions, the event loop is structured a
bit differently not hammering the clients with updates
but rather batching them over a short, configurable time
which should significantly improve cpu usage, and potentially
flakyness.
The use of Patch updates has been dialed back a little as
it does not look like its a 100% ready for prime time. Nodes
are now updated with full changes, except for a few things
like online status.
