This patch provides symmetric hash support according to source ip address and port, and destination ip address and port. For this purpose, the __skb_get_hash_symmetric() is used to identify the flow as it uses FLOW_DISSECTOR_F_STOP_AT_FLOW_LABEL flag by default. The new attribute NFTA_HASH_TYPE has been included to support different types of hashing functions. Currently supported NFT_HASH_JENKINS through jhash and NFT_HASH_SYM through symhash. The main difference between both types are: - jhash requires an expression with sreg, symhash doesn't. - symhash supports modulus and offset, but not seed. Examples: nft add rule ip nat prerouting ct mark set jhash ip saddr mod 2 nft add rule ip nat prerouting ct mark set symhash mod 2 By default, jenkins hash will be used if no hash type is provided for compatibility reasons.
