* Fix race condition and ensure correct message ordering in
connection establishment
Reorder operations in OpenConn to register the connection before
waiting for peer availability. This ensures:
- Connection is ready to receive messages before peer subscription
completes
- Transport messages and onconnected events maintain proper ordering
- No messages are lost during the connection establishment window
- Concurrent OpenConn calls cannot create duplicate connections
If peer availability check fails, the pre-registered connection is
properly cleaned up.
* Handle service shutdown during relay connection initialization
Ensure relay connections are properly cleaned up when the service is not running by verifying `serviceIsRunning` and removing stale entries from `c.conns` to prevent unintended behaviors.
* Add gRPC update debouncing mechanism
Implements backpressure handling for peer network map updates to
efficiently handle rapid changes. First update is sent immediately,
subsequent rapid updates are coalesced, ensuring only the latest
update is sent after a 1-second quiet period.
* Enhance unit test to verify peer count synchronization with debouncing and timeout handling
* Debounce based on type
* Refactor test to validate timer restart after pending update dispatch
* Simplify timer reset for Go 1.23+ automatic channel draining
Remove manual channel drain in resetTimer() since Go 1.23+ automatically
drains the timer channel when Stop() returns false, making the
select-case pattern unnecessary.
- Add WireguardPort option to embed.Options for custom port configuration
- Fix KernelInterface detection to account for netstack mode
- Skip SSH config updates when running in netstack mode
- Skip interface removal wait when running in netstack mode
- Use BindListener for netstack to avoid port conflicts on same host
Add defensive nil checks in ThreadSafeAgent.Close() to prevent panic
when agent field is nil. This can occur during Windows suspend/resume
when network interfaces are disrupted or the pion/ice library returns
nil without error.
Also capture agent pointer in local variable before goroutine execution
to prevent race conditions.
Fixes service crashes on laptop wake-up.
Avoid repeated conversions during route setup. The toInterface helper ensures
the conversion happens only once regardless of how many routes are added
or removed.
Add LocalAuthDisabled option to embedded IdP configuration
This adds the ability to disable local (email/password) authentication when using the embedded Dex identity provider. When disabled, users can only authenticate via external
identity providers (Google, OIDC, etc.).
This simplifies user login when there is only one external IdP configured. The login page will redirect directly to the IdP login page.
Key changes:
Added LocalAuthDisabled field to EmbeddedIdPConfig
Added methods to check and toggle local auth: IsLocalAuthEnabled, HasNonLocalConnectors, DisableLocalAuth, EnableLocalAuth
Validation prevents disabling local auth if no external connectors are configured
Existing local users are preserved when disabled and can login again when re-enabled
Operations are idempotent (disabling already disabled is a no-op)
Start the WireGuard watcher before configuring the WG endpoint to ensure it captures the initial handshake timestamp.
Previously, the watcher was started after endpoint configuration, causing it to miss the handshake that occurred during setup.
When a deleted peer tries to reconnect, GetUserIDByPeerKey was returning
Internal error instead of NotFound, causing clients to retry indefinitely
instead of recognizing the unrecoverable PermissionDenied error.
This fix:
1. Updates GetUserIDByPeerKey to properly return NotFound when peer doesn't exist
2. Updates Sync handler to convert NotFound to PermissionDenied with message
'peer is not registered', matching the behavior of GetAccountIDForPeerKey
Fixes the regression introduced in v0.61.1 where deleted peers would see:
- Before: 'rpc error: code = Internal desc = failed handling request' (retry loop)
- After: 'rpc error: code = PermissionDenied desc = peer is not registered' (exits)
* Add IPv6 support to UDP WireGuard proxy
Add IPv6 packet header support in UDP raw socket proxy
to handle both IPv4 and IPv6 source addresses.
Refactor error handling in proxy bind implementations
to validate endpoints before acquiring locks.
* Consolidate authentication logic
- Moving auth functions from client/internal to client/internal/auth package
- Creating unified auth.Auth client with NewAuth() constructor
- Replacing direct auth function calls with auth client methods
- Refactoring device flow and PKCE flow implementations
- Updating iOS/Android/server code to use new auth client API
* Refactor PKCE auth and login methods
- Remove unnecessary internal package reference in PKCE flow test
- Adjust context assignment placement in iOS and Android login methods
