Worked on the cilium/tetragon repository to enhance reliability and safety in the kprobe enforcement path, focusing on backend development and policy enforcement using Go. Addressed a runtime risk by hardening the validation logic for KprobeSpec with NotifyEnforcer, ensuring that at least one EnforcerSpec is required for proper configuration. Introduced a dedicated helper function and updated the validation flow to prevent misconfigurations that could compromise enforcement consistency. This targeted bug fix improved system programming robustness by rejecting NotifyEnforcer kprobe actions lacking an Enforcer, thereby reducing potential runtime errors and contributing to more consistent and predictable policy enforcement behavior.
