Mykyta Yatsenko 7b30c296af libbpbpf: Check bpf_map/bpf_program fd validity ... libbpf creates bpf_program/bpf_map structs for each program/map that user defines, but it allows to disable creating/loading those objects in kernel, in that case they won't have associated file descriptor (fd < 0). Such functionality is used for backward compatibility with some older kernels. Nothing prevents users from passing these maps or programs with no kernel counterpart to libbpf APIs. This change introduces explicit checks for kernel objects existence, aiming to improve visibility of those edge cases and provide meaningful warnings to users.
