Implement user group validation during OAuth callback to ensure users
belong to allowed distribution groups before granting access to reverse
proxies. This provides account isolation and fine-grained access control.
Key changes:
- Add ValidateUserGroupAccess to ProxyServiceServer for group membership checks
- Redirect denied users to error page with access_denied parameter
- Handle OAuth error responses in proxy middleware
- Add comprehensive integration tests for auth callback flow
- Rewrite Host header to backend target (configurable via pass_host_header per mapping)
- Strip and set X-Forwarded-For/X-Real-IP from direct connection (trust boundary)
- Set X-Forwarded-Host and X-Forwarded-Proto headers
- Strip nb_session cookie and session_token query param before forwarding
- Add --forwarded-proto flag (auto/http/https) for proto detection
- Fix OIDC redirect hardcoded https scheme
- Add pass_host_header to proto, API, and management model
* 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.
- Log proxy address and cluster info when proxy connects
- Log connected proxy URLs when GetConnectedProxyURLs is called
- Log proxy allow list when GetDomains is called
- Helps debug issues with free domains not appearing in API response
