ENUM NFT_IMMEDIATE_ATTRIBUTES(9)

💖 enum nft_immediate_attributes — the nf_tables immediate expression netlink attributes, bestie 💅

okay so this is a page from the Kernel API Manual (section 9, kernel devcorner ✨) and it's all about one lil enum that lives in the kernel headers. it's the netlink attribute list for the nf_tables immediate expression — yep, the thing that literally loads a value into a register. main character energy fr fr 👑

---

🌸 SYNOPSIS 🌸

like, here's the whole thing, verbatim, no cap:

enum nft_immediate_attributes {
    NFTA_IMMEDIATE_UNSPEC ,
    NFTA_IMMEDIATE_DREG ,
    NFTA_IMMEDIATE_DATA ,
    __NFTA_IMMEDIATE_MAX

};

---

✨ CONSTANTS ✨

these are the members, and yes bestie i'm listing every single one 🫶

• NFTA_IMMEDIATE_UNSPEC — so this one is literally marked -- undescribed -- in the source docs 😭 that's it, that's the whole description. iconic in a mysterious way tbh.
• NFTA_IMMEDIATE_DREG — the destination register you're loading data into. type is NLA_U32. this is where the value goes 🎯
• NFTA_IMMEDIATE_DATA — the actual data being loaded. type is NLA_NESTED: nft_data_attributes, so it's nested, inside it there's a whole other attribute party going on 🪆
• __NFTA_IMMEDIATE_MAX — also -- undescribed -- 🙈 it's the internal max marker, the sentinel vibe check at the end of the list.

👑 SEE ALSO 👑

okay this list is LONG and i'm not skipping a single one because every single one of these is a real reference and skipping them would be a crime 💀🔪

ngl that's 78 refs, i counted, and every one of them is a real page you can pull up. go read them, bestie, become the netlink encyclopaedia you were always meant to be 🦋

and that's the page!! 🎀 source lives under ./include/uapi/linux/netfilter, and this version is dated October 2026 — so yeah, future-coded manpage, slay. until next time, stay nested and stay NLA_U32 💜⭐
