How to Attach a BPF_PROG_TYPE_SK_MSG
fengzx33 opened this issue · comments
@fengzx33 I suppose you can get information about BPF_PROG_TYPE_SK_MSG from the kernel Documentation/bpf/map_sockmap.rst and through the use of its helpers in tools/testing/selftests/bpf/progs/test_sockmap_kern.h.
@rafaeldtinoco we currently don't support bpf_msg_push_data and bpf_msg_pull_data, right?
@geyslan Thank you, but what I would like to know is how to successfully attach to a SEC like SEC("sk_msg") using libbpfgo. I am looking for a function similar to AttachCgroup(cgroupV2DirPath string) or the steps required for attaching to such SEC("sk_msg") using libbpfgo.
@geyslan @rafaeldtinoco I found that libbpfgo haven't an api, which can attach SEC("sk_msg") , what should i do? thanks
