Daniel Borkmann 2ec0616e87 bpf: Fix check_return_code to only allow [0,1] in trace_iter progs ... As per 15d83c4d7c ("bpf: Allow loading of a bpf_iter program") we only allow a range of [0,1] for return codes. Therefore BPF_TRACE_ITER relies on the default tnum_range(0, 1) which is set in range var. On recent merge of net into net-next commit e92888c72f ("bpf: Enforce returning 0 for fentry/fexit progs") got pulled in and caused a merge conflict with the changes from 15d83c4d7c. The resolution had a snall hiccup in that it removed the [0,1] range restriction again so that BPF_TRACE_ITER would have no enforcement. Fix it by adding it back.
