Custom distribution (Yocto Kirkstone) using 5.10.184.All parts (kernel, DPDK, libbpf, xdp-tools) are built (cross-compiled) from source. > BPF/XDP has changed a lot over last couple of years and not maintained > compatibility.

If getting from a distro (Fedora, Ubuntu, Debian, > etc) Using libbpf 0.7.0 and libxdp 1.2.8, which are provided by meta-intel, it doesn't work. I tried the latest version libbpf 1.3.0 and libxdp 1.4.2 and unfortunately It still doesn't work The output changed a little: libbpf: prog 'xdp_dispatcher': failed to load: -22 libbpf: failed to load object 'xdp-dispatcher.o' libxdp: Failed to load dispatcher: Invalid argument libxdp: Falling back to loading single prog without dispatcher libbpf: elf: skipping unrecognized data section(7) xdp_metadata libbpf: prog 'xdp_dispatcher': BPF program load failed: Invalid argument libbpf: prog 'xdp_dispatcher': -- BEGIN PROG LOAD LOG -- Validating prog0() func#1... btf_vmlinux is malformed Arg#0 type PTR in prog0() is not supported yet. > then make sure that xdp and kernel match. Where can I find that match table between xdp and kernel? Thanks a lot! Ciao, Alessio
