samples/bpf: Add XDP_SHARED_UMEM support to xdpsock Add support for the XDP_SHARED_UMEM mode to the xdpsock sample application. As libbpf does not have a built in XDP program for this mode, we use an explicitly loaded XDP program. This also serves as an example on how to write your own XDP program that can route to an AF_XDP socket.

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 2020-12-03 09:05:46 +00:00			`#define SOCKET_NAME "sock_cal_bpf_fd"`
