Lorenz Bauer 6550f2dddf bpf: sockmap: Enable map_update_elem from bpf_iter ... Allow passing a pointer to a BTF struct sock_common* when updating a sockmap or sockhash. Since BTF pointers can fault and therefore be NULL at runtime we need to add an additional !sk check to sock_map_update_elem. Since we may be passed a request or timewait socket we also need to check sk_fullsock. Doing this allows calling map_update_elem on sockmap from bpf_iter context, which uses BTF pointers.
