The Calico Node pods are encountering eXpress Data Path state failures and Berkeley Packet Filter program loading errors, specifically

Failure to wipe XDP state due to a missing file

failed to load BPF program (/usr/lib/calico/bpf/filter.o): stat /sys/fs/bpf/calico/xdp/prefilter_v1_calico_tmp_A: no such file or directory

BPF Type Format loading errors, indicating a possible kernel or compatibility issue

libbpf: Error loading BTF: Invalid argument(22)
libbpf: Error loading .BTF into kernel: -22.

I have successfully recreated the problem on two separate clusters from a clean/new build here is an extract from an example RM document.

  • This occurs on all Ubuntu-based cluster nodes, affecting both system and user nodes.
  • This occurs on Kubernetes version 1.29.x, but needs testing across all supported Kubernetes versions.
  • The error messages are continuous—across three nodes, our aggregator collected 2.5GB of log data in a 30-minute period (likely more).
  • We cannot stop this; the only option is to disable Calico.

To Reproduce
Build a cluster & configure networkPolicy: calico, enableFIPS: true, networkPlugin: azure

kubectl logs -n calico-system -l k8s-app=calico-node --tail=50 --follow
