Setup Requirements

The project requires a Linux system with the following features:

• Kernel ≥5.13

uname -r

• BPF LSM enabled

cat /sys/kernel/security/lsm | grep bpf

• cgroup v2 mounted

mount | grep cgroup2

• Capabilities CAP_BPF and CAP_SYS_ADMIN

capsh --print | grep -E 'cap_(bpf|sys_admin)'

Building prebuilt BPF objects

Generate the prebuilt BPF artifacts with:

scripts/build-bpf.sh

The script installs the nightly toolchain, required components and the bpf-linker before placing the resulting object files under prebuilt/<arch>.

Generated artifacts are excluded from version control; rerun the script to refresh them.
