From bbaf6029c49ccf2dc93d9564af58a20d125947a1 Mon Sep 17 00:00:00 2001 From: Maciej Fijalkowski Date: Fri, 1 Feb 2019 22:42:25 +0100 Subject: samples/bpf: Convert XDP samples to libbpf usage Some of XDP samples that are attaching the bpf program to the interface via libbpf's bpf_set_link_xdp_fd are still using the bpf_load.c for loading and manipulating the ebpf program and maps. Convert them to do this through libbpf usage and remove bpf_load from the picture. While at it remove what looks like debug leftover in xdp_redirect_map_user.c In xdp_redirect_cpu, change the way that the program to be loaded onto interface is chosen - user now needs to pass the program's section name instead of the relative number. In case of typo print out the section names to choose from.
