Abstract: Managing execution of eBPF program capabilities is provided. A comparison of a currently in use helper-id list with an allowable helper-id list of an eBPF program is performed. It is determined whether a set of unallowable helper-ids exists that is included in the currently in use helper-id list but not in the allowable helper-id list based on the comparison.

An AV management system can run a simulation of an AV autonomously piloting itself and collect simulation driving data. Further, the AV management system can parse the simulation driving data into kinematic and semantic environmental features and output a simulation safety score of the simulation based on the kinematic and semantic environmental features. The simulation safety score indicates a probability of a safety critical event such as a collision or a near-miss between the AV and the at least one simulated object in the simulation.
