XDP program fails to load when benchmark=True is set in Mizar kind-setup deployment #485

Closed vinaykul closed 2 years ago

vinaykul commented 3 years ago

To repro this issue, do the following:

  1. In mizar codebase, set benchmark=true in mizar/common/rpc.py and mizar/daemon/interface_service.py
  2. Deploy a two-worker kind cluster: './kind-setup dev 2'
  3. Inspect the XDP programs loaded on veth-hostep@eth-hostep in the kind-worker nodes. This would be missing.
  4. Inspect the mizar-daemon logs. It contains message such as "bpf failed to load program permission denied"
  5. The above does not occur when running with DEBUG enabled (i.e. ebp_debug.o programs are loaded)

This should work regardless of whether _ebpf.o or ebpf_debug.o program binaries are used.
