Alexei Starovoitov 89aa075832 net: sock: allow eBPF programs to be attached to sockets ... introduce new setsockopt() command: setsockopt(sock, SOL_SOCKET, SO_ATTACH_BPF, &prog_fd, sizeof(prog_fd)) where prog_fd was received from syscall bpf(BPF_PROG_LOAD, attr, ...) and attr->prog_type == BPF_PROG_TYPE_SOCKET_FILTER setsockopt() calls bpf_prog_get() which increments refcnt of the program, so it doesn't get unloaded while socket is using the program. The same eBPF program can be attached to multiple sockets. User task exit automatically closes socket which calls sk_filter_uncharge() which decrements refcnt of eBPF program Signed-off-by: Alexei Starovoitov <ast@plumgrid.com> Signed-off-by: David S.
