ENUM NFT_TPROXY_ATTRIBUTES(9)

💖 enum nft_tproxy_attributes(9) — the nf_tables tproxy netlink attributes enum, bestie edition 🎀

okay so this is a page from the Kernel API Manual, and it's literally all about enum nft_tproxy_attributes — the netlink attributes for the nf_tables tproxy expression. iykyk 💅

✨ NAME ✨

enum nft_tproxy_attributes — nf_tables tproxy expression netlink attributes 🦋

🌸 SYNOPSIS 🌸

enum nft_tproxy_attributes {
    NFTA_TPROXY_UNSPEC ,
    NFTA_TPROXY_FAMILY ,
    NFTA_TPROXY_REG_ADDR ,
    NFTA_TPROXY_REG_PORT ,
    __NFTA_TPROXY_MAX

};

like, that's the whole enum. five little entries. iconic. 👑

💜 CONSTANTS 💜

• NFTA_TPROXY_UNSPEC — okay so the manual literally just says -- undescribed -- here 🙈 no cap, that's all we get. it's the unspecified one, she's mysterious, she's giving main character energy without a backstory.
• NFTA_TPROXY_FAMILY — the target address family, and it's typed NLA_U32: nft_registers ⭐
• NFTA_TPROXY_REG_ADDR — the target address register, also NLA_U32: nft_registers 💖
• NFTA_TPROXY_REG_PORT — the target port register, again NLA_U32: nft_registers ✨
• __NFTA_TPROXY_MAX — and this one is also -- undescribed -- 💀 the manpage has spoken (said nothing).

ngl bestie, the NLA_U32: nft_registers on three of these is the whole lore — that's the type annotation right there in the source, don't come for me, i'm just relaying it. 🫶
