samples/bpf: Sample application for eBPF load and socket creation split
Introduce a sample program to demonstrate the control and data plane split. For the control plane part a new program called xdpsock_ctrl_proc is introduced. For the data plane part, some code was added to xdpsock_user.c to act as the data plane entity. Application xdpsock_ctrl_proc works as control entity with sudo privileges (CAP_SYS_ADMIN and CAP_NET_ADMIN are sufficient) and the extended xdpsock as data plane entity with CAP_NET_RAW capability only. Usage example: sudo ./samples/bpf/xdpsock_ctrl_proc -i <interface> sudo ./samples/bpf/xdpsock -i <interface> -q <queue_id> -n <interval> -N -l -R Signed-off-by: Mariusz Dudek <mariuszx.dudek@intel.com> Signed-off-by: Alexei Starovoitov <ast@kernel.org> Acked-by: Magnus Karlsson <magnus.karlsson@intel.com> Link: https://lore.kernel.org/bpf/20201203090546.11976-3-mariuszx.dudek@intel.com
