Daniel Borkmann 14a3d3ef02 bpf: Remove MEM_UNINIT from skb/xdp MTU helpers ... We can now undo parts of 4b3786a6c5 ("bpf: Zero former ARG_PTR_TO_{LONG,INT} args in case of error") as discussed in [0]. Given the BPF helpers now have MEM_WRITE tag, the MEM_UNINIT can be cleared. The mtu_len is an input as well as output argument, meaning, the BPF program has to set it to something. It cannot be uninitialized. Therefore, allowing uninitialized memory and zeroing it on error would be odd. It was done as an interim step in 4b3786a6c5 as the desired behavior could not have been expressed before the introduction of MEM_WRITE tag.
