Daniel Borkmann 47cc0ed574 bpf: Add bpf_probe_read_{user, kernel}_str() to do_refine_retval_range ... Given bpf_probe_read{,str}() BPF helpers are now only available under CONFIG_ARCH_HAS_NON_OVERLAPPING_ADDRESS_SPACE, we need to add the drop-in replacements of bpf_probe_read_{kernel,user}_str() to do_refine_retval_range() as well to avoid hitting the same issue as in 849fa50662 ("bpf/verifier: refine retval R0 state for bpf_get_stack helper").
