[ Upstream commit405b93eb76] The current ARFS code relies on certain fields to be set in the SKB (e.g. transport_header) and extracts IP addresses and ports by custom code that parses the packet. The necessary SKB fields, however, are not always set at that point, which leads to an out-of-bounds access. Use skb_flow_dissect_flow_keys() to get the necessary information reliably, fix the out-of-bounds access and reuse the code.
