Subject: [PATCH bpf-next] samples/bpf: Fix sockex3: missing BPF prog type
Date: Sat, 29 Oct 2022 15:53:12 +0800 [thread overview]
Message-ID: <tencent_7DD02046A8398BE3324F85E0F56ED41EB105@qq.com> (raw)
In-Reply-To: <CAEf4Bza_6qND8iOuiur+xX0cBVkKJfKoJAOjihnVYRjoB3tWqw@mail.gmail.com>
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
