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. A blocked helper-id list of the eBPF program that includes the set of unallowable helper-ids and a corresponding unallowable capability of each respective unallowable helper-id is generated in response to determining that the set of unallowable helper-ids does exist. The set of unallowable helper-ids and the corresponding unallowable capability of each respective unallowable helper-id is removed from bytecode of the eBPF program in order to have only allowable helper-ids remain in the bytecode along with corresponding allowable capabilities of the eBPF program.

Embodiments are directed to using remote pods. An intermediary software is instantiated in a worker node virtual machine and is used to cause a pod virtual machine to be created, the pod virtual machine being remote from the worker node virtual machine. An overlay network is established between the intermediary software in the worker node virtual machine and a pod space in the pod virtual machine. The overlay network is used to cause containers to be created in the pod virtual machine, where the worker node virtual machine is configured to use the overlay network to manage communications with the pod virtual machine.

Embodiments of the present disclosure relate to methods, systems, and computer program products for event management. In a method, a token is obtained at a first agent device that is included in a network system, the token is for authenticating a first packet that is transmitted in the network system, and the first packet is generated according to a first network format. A second packet is generated based on the first packet and the token according to a second network format. The second packet is transmitted to a second agent device that is included in the network system, here both of the first and second agent devices support the first and second network formats. With these embodiments, the packet may be authenticated in a more effective way.
