Investigate mechanisms for integration of extracted modules with L3AF/Polycube

[sdsen]

We want to be able to create L3AF NF modules modules with code extracted from large monoliths like Katran, Cilium etc. The task will involve:

1. extracting modules using tool from this repo.
2. writing appropriate wrappers for L3AF
3. Simple user-code using https://github.com/eBPFDevSecTools/ebpf-client-sdk

To clear, L3AFD will be used to package and run the extracted module and mapaccess-sdk will be used to provide the userspace side of access to the module if needed.

1. L3AFD -

• Setup the dev environment as suggested by L3AF
• Package the extracted function and submit it to the L3AF via a call to L3AF daemon's API
• Test if the program gets loaded and attaches to the desired interface by looking at the system state.

1. ebpf-mapaccess-sdk -

• For userspace side of things if needed look at the README which contains information on how to run the sdk and interact with an ebpf program.
