From: Rong Tao <rongtao@cestc.cn>
since commit 450b167fb9be("libbpf: clean up SEC() handling"), sec_def_matches() does not recognize "socket/xxx" as "socket", therefore, the BPF program type is not recognized, set "socket/xxx" to SOCKET_FILTER solves this error.
$ cd samples/bpf $ sudo ./sockex3 libbpf: prog 'bpf_func_PARSE_IP': missing BPF prog type, check ELF section name 'socket/3' libbpf: prog 'bpf_func_PARSE_IP': failed to load: -22 libbpf: failed to load object './sockex3_kern.o' ERROR: loading BPF object file failed
