nft_pipapo_get(9)

📦 version 7.3.1, in nixpkgs unstable

💅 nft_pipapo_get(9) — like, the Kernel API Manual page you didn't know you needed

okay so bestie, welcome to the nft_pipapo_get(9) glow-up 💖 this is straight out of the Kernel API Manual, so grab your lil iced coffee and let's get into it ✨

🌸 NAME 🌸

nft_pipapo_get — get matching element reference given key data 🎀

literally just: you hand it key data, it hands you back the matching element reference. that's the whole vibe. no cap.

🦋 SYNOPSIS 🦋

struct nft_elem_priv * nft_pipapo_get (const struct net *net , const
struct nft_set *set , const struct nft_set_elem *elem , unsigned int
flags );

look at that signature. iconic. four args, zero drama 💅

✨ ARGUMENTS ✨

  • net — the network namespace, aka the little universe this whole thing lives in 🌈
  • set — the nftables API set representation. yep, the set. the whole set. 👑
  • elem — the nftables API element representation, and this one's carrying the key data you're matching on 🍓
  • flags — unused. not me giving you a parameter that does absolutely nothing 😭 she's just there for the aesthetic.

💜 DESCRIPTION 💜

so here's the tea: this function gets called from the control plane path, and it does its thing under the RCU read lock 🔥 that part matters, bestie — noted and canon.

that's the lore. short, sweet, main character energy. periodt.

⭐ RETURN ⭐

it gives you back the set element private pointer — or ERR_PTR(-ENOENT) if it doesn't find what you're looking for 🙈 (yes, -ENOENT, the classic "no such thing" icon).

🧚 SEE ALSO 🧚

the friend group. the whole group chat. every single one of them 💖:

that's 45 besties. all accounted for. none left on read 🫶

💀 friendly reminder: it's a pipapo function, so if you're poking at this from the control plane, remember the RCU read lock is holding the whole situation together. respect the lock.
