ENUM NFT_CONNLIMIT_ATTRIBUTES(9)

💅 enum nft_connlimit_attributes(9) 💅

okay so this is a page straight out of the Kernel API Manual (yes, that's the manual name, we're fancy now ✨) and it's all about enum nft_connlimit_attributes — the nf_tables connlimit expression netlink attributes. Netlink attributes, bestie. The little labelled boxes the kernel and userspace pass back and forth. It's giving "unboxing video but make it kernel" 🎀

✨ NAME ✨

enum nft_connlimit_attributes — nf_tables connlimit expression netlink attributes 🦋

---

🌸 SYNOPSIS 🌸

Here's the whole enum, verbatim, treat it like a sacred text:

enum nft_connlimit_attributes {
    NFTA_CONNLIMIT_UNSPEC ,
    NFTA_CONNLIMIT_COUNT ,
    NFTA_CONNLIMIT_FLAGS ,
    __NFTA_CONNLIMIT_MAX

};

That's it. Four entries. Iconic, minimal, ate. 👑

---

💖 Constants 💖

Let's meet the actual members, one by one, no skips:

• NFTA_CONNLIMIT_UNSPEC — literally no description in the source 💀 -- undescribed --. It's the mystery member. The unspec one. We respect its privacy.
• NFTA_CONNLIMIT_COUNT — the number of connections, carried as NLA_U32. That's the whole vibe: how many conns are we capping at 🔥
• NFTA_CONNLIMIT_FLAGS — the flags, carried as NLA_U32: enum nft_connlimit_flags. Yeah, it points at a whole other enum, we love a crossover episode 🫶
• __NFTA_CONNLIMIT_MAX — also -- undescribed -- 😭 so I'm not gonna invent lore for it. It's the max sentinel, it's mysterious, it's doing main character energy in silence.

ngl bestie, two of these members have no description at all in the source — NFTA_CONNLIMIT_UNSPEC and __NFTA_CONNLIMIT_MAX. That's not me being lazy, that's genuinely what the page says. Don't @ me 💀

okay and that's the whole page, mwah 💋 sign-off time: this came from the source tree at ./include/uapi/linux/netfilter, dated October 2026. Slay, see you in the next (9) page 🧚‍♀️💜
