nla_data(9)

📦 version 7.3.1, in nixpkgs unstable

💅 NAME 💅

Welcome to nla_data(9), straight out of the Kernel API Manual — and bestie, she does exactly one thing and she does it iconically.

nla_data — head of payload. That's it, that's the whole vibe. 🎀

✨ SYNOPSIS ✨

void * nla_data (const struct nlattr *nla );

Literally one line, no cap. You hand her a netlink attribute, she hands you back a void * pointing at the head of the payload. That's the whole transaction. 💖

🦋 ARGUMENTS 🦋

  • nla — netlink attribute. Like, the attribute itself, okay? You give her the attribute and she gives you the head of its payload. Main character energy from both of you tbh. 🫶

🌸 SEE ALSO 🌸

Okay so this list is long, but you asked for the whole thing so here's the whole thing, in order, no skips, no shortcuts. Sit down, hydrate, we're doing this. 💀

  • ./include/net/netlink.h — the kernel file itself, go read the source, it's giving homework but make it fun
  • struct nla_policy(9)
  • struct nl_info(9)
  • enum netlink_validation(9)

The nlmsg_ fundamentals ⭐

Parsing + validating squad 🔥

Message building + iterating, the whole ensemble 🌈

Sizes, types, and peeking at attributes 🧚

The nla_put_* family — the placing-your-stuff girlies 🍓

The nla_get_* family — the getting-it-back girlies (and yes, there are _default versions of almost everything, they ate) 👑

Nesting, duping, padding + the iterator crew 🦋

That's every single one, fr fr — nothing skipped, nothing merged. If you need the deep lore on any of them, they've all got their own pages. iykyk. 💜

And that's the page, bestie! This one lives in ./include/net and it's dated October 2026 — so like, future vibes, periodt. Go call nla_data() and get that payload head. Slay. 💅✨
