Daniel Borkmann 21cafc1dc2 bpf: remove artificial bpf_skb_{load, store}_bytes buffer limitation ... We currently limit bpf_skb_store_bytes() and bpf_skb_load_bytes() helpers to only store or load a maximum buffer of 16 bytes. Thus, loading, rewriting and storing headers require several bpf_skb_load_bytes() and bpf_skb_store_bytes() calls. Also here we can use a per-cpu scratch buffer instead in order to not pressure stack space any further. I do suspect that this limit was mainly set in place for this particular reason. So, ease program development by removing this limitation and make the scratchpad generic, so it can be reused.
