- Renamed test functions in `client_tls_clienthello_truncation_adversarial_tests.rs` to remove "but_leaks" suffix for clarity.
- Added new tests in `direct_relay_business_logic_tests.rs` to validate business logic for data center resolution and scope hints.
- Introduced tests in `direct_relay_common_mistakes_tests.rs` to cover common mistakes in direct relay configurations.
- Added security tests in `direct_relay_security_tests.rs` to ensure proper handling of symlink and parent swap scenarios.
- Created `direct_relay_subtle_adversarial_tests.rs` to stress test concurrent logging and validate scope hint behavior.
- Implemented `relay_quota_lock_pressure_adversarial_tests.rs` to test quota lock behavior under high contention and stress.
- Updated `relay_security_tests.rs` to include quota lock contention tests ensuring proper behavior under concurrent access.
- Introduced `ip_tracker_hotpath_adversarial_tests.rs` to validate the performance and correctness of the IP tracking logic under various scenarios.
- Introduced adversarial tests to validate the behavior of the health monitoring system under various conditions, including the management of draining writers.
- Implemented integration tests to ensure the health monitor correctly handles expired and empty draining writers.
- Added regression tests to verify the functionality of the draining writers' cleanup process, ensuring it adheres to the defined thresholds and budgets.
- Updated the module structure to include the new test files for better organization and maintainability.
Added new endpoints:
- GET /v1/system/info
- GET /v1/runtime/gates
- GET /v1/limits/effective
- GET /v1/security/posture
Added API runtime state without impacting the hot path:
- config_reload_count
- last_config_reload_epoch_secs
- admission_open
- process_started_at_epoch_secs
Added background watcher tasks in api::serve:
- configuration reload tracking
- admission gate state tracking
- Per-user ad_tag in [access.user_ad_tags], global fallback in general.ad_tag
- User tag overrides global; if no user tag, general.ad_tag is used
- Both general.ad_tag and user_ad_tags support hot-reload (no restart)
Adds mask_proxy_protocol config option (0 = off, 1 = v1 text, 2 = v2 binary)
that sends a PROXY protocol header when connecting to mask_host. This lets
the backend see the real client IP address.
Particularly useful when the masking site (nginx/HAProxy) runs on the same
host as telemt and listens on a local port — without this, the backend loses
the original client IP entirely.
PROXY protocol header is also sent during TLS emulation fetches so that
backends with proxy_protocol required don't reject the connection.
