ENUM NF_TABLES_MSG_TYPES(9)

💅 enum nf_tables_msg_types(9) — the Kernel API Manual, bestie edition

okay so picture this: you're deep in the kernel API manual (that's the manual name, iykyk) and you hit this page. It's enum nf_tables_msg_types, and it's literally the guest list for every netlink message type nf_tables can send. Every create, every get, every delete, every destroy — all of them are here. Slay.

• NFT_MSG_GETOBJ_RESET — get and reset a stateful object (enum nft_obj_attributes)
• NFT_MSG_NEWFLOWTABLE — add new flow table (enum nft_flowtable_attributes)
• NFT_MSG_GETFLOWTABLE — get flow table (enum nft_flowtable_attributes)
• NFT_MSG_DELFLOWTABLE — delete flow table (enum nft_flowtable_attributes)
• NFT_MSG_GETRULE_RESET — get rules and reset stateful expressions (enum nft_obj_attributes)
• NFT_MSG_DESTROYTABLE — destroy a table (enum nft_table_attributes)
• NFT_MSG_DESTROYCHAIN — destroy a chain (enum nft_chain_attributes)
• NFT_MSG_DESTROYRULE — destroy a rule (enum nft_rule_attributes)

ngl the GET*_RESET ones are doing the most — get and reset in one message? main character energy fr fr.
