    libbpf: Show supported ELF section names when failing to guess prog/attach type · c76e4c22
    Taeung Song authored
    We need to let users check their wrong ELF section name with proper
    ELF section names when they fail to get a prog/attach type from it.
    Because users can't realize libbpf guess prog/attach types from given
    ELF section names. For example, when a 'cgroup' section name of a
    BPF program is used, show available ELF section names(types).
    
    Before:
    
        $ bpftool prog load bpf-prog.o /sys/fs/bpf/prog1
        Error: failed to guess program type based on ELF section name cgroup
    
    After:
    
        libbpf: failed to guess program type based on ELF section name 'cgroup'
        libbpf: supported section(type) names are: socket kprobe/ kretprobe/ classifier action tracepoint/ raw_tracepoint/ xdp perf_event lwt_in lwt_out lwt_xmit lwt_seg6local cgroup_skb/ingress cgroup_skb/egress cgroup/skb cgroup/sock cgroup/post_bind4 cgroup/post_bind6 cgroup/dev sockops sk_skb/stream_parser sk_skb/stream_verdict sk_skb sk_msg lirc_mode2 flow_dissector cgroup/bind4 cgroup/bind6 cgroup/connect4 cgroup/connect6 cgroup/sendmsg4 cgroup/sendmsg6
