Add required eBPF kernel configurations

[kbrighton]

I've been attempting to run the cilium CNI plugin (as well as the Calico CNI plugin) via rke2, and it's not been working correctly, due to missing eBPF kernel configurations:

The requirements for these CNI plugins are: CONFIG_BPF=y CONFIG_BPF_SYSCALL=y CONFIG_NET_CLS_BPF=y CONFIG_BPF_JIT=y CONFIG_NET_CLS_ACT=y CONFIG_NET_SCH_INGRESS=y CONFIG_CRYPTO_SHA1=y CONFIG_CRYPTO_USER_API_HASH=y CONFIG_CGROUPS=y CONFIG_CGROUP_BPF=y CONFIG_PERF_EVENTS=y CONFIG_SCHEDSTATS=y

We seem to be missing: CONFIG_NET_CLS_BPF=y CONFIG_CRYPTO_USER_API_HASH=y CONFIG_CGROUPS=y CONFIG_PERF_EVENTS=y CONFIG_SCHEDSTATS=y

If those could be added to the quartz64_defconfig file, at the very least, it would be very helpful.

Which SBC are you referring to? We control the kernel configuration for Quartz64, VisionFive 2 and Star64 only. For all other SBC/PC images we use externally managed kernel packages, from Debian, Armbian or the respective vendors.

It would be the quartz64, I believe.

Does this work on Raspberry Pi (RPi OS)? It misses CONFIG_NET_CLS_BPF as well. Debian and Armbian kernels however ships with it, hence I think it is common enough for us to add it as well.

Done with: https://github.com/MichaIng/DietPi/commit/8d572699 Kernel builds running: https://github.com/MichaIng/DietPi/actions/runs/9530987096 I'll do the same for VisionFive 2 and Star64.

All done, please try:

apt update
apt upgrade
reboot
