llc_ui_create(9)

📦 version 7.3.1, in nixpkgs unstable

💅 llc_ui_create 💅

okay so bestie, welcome to the Kernel API Manual — this one's a lil' kernel function called llc_ui_create(9) and honestly? it's giving socket-birth energy. it allocs, it inits, it validates. we love a triple threat. 🎀

✨ NAME ✨

llc_ui_create — alloc and init a new llc_ui socket. that's it, that's the whole gig. 🫶

🌸 SYNOPSIS 🌸

int llc_ui_create (struct net *net , struct socket *sock , int protocol
, int kern );

four params, one int coming back atcha. iconic signature tbh. ⭐

🦋 ARGUMENTS 🦋

  • net — the network namespace, and hear me out: it must be default network. like, it's not a suggestion, it's a vibe check and only one thing passes. 💀
  • sock — the socket you're gonna initialize and attach the allocated sk to. this is where the new baby lives. 🍼
  • protocol — unused. literally sits there looking pretty. not me respecting the parameter anyway. 🙈
  • kern — tells us whether this is on behalf of the kernel or userspace. main character ambiguity, resolved. 👑

💖 DESCRIPTION 💖

so what actually happens? it allocates and initializes a fresh new llc_ui socket, and it validates that the user actually wants a socket type we have available. no cap, that's the whole thing.

return value time: 0 on success (slay ✨), negative on failure (😭). that's the contract, bestie, don't fight it.

🔥 SEE ALSO 🔥

the kernel file ./net/llc/af_llc.c is where the magic lives, and it's surrounded by the entire friend group. so many siblings, so much lore:

like, they're all in the group chat. go say hi. 🫶

ngl the whole page is small but it ate. short king behavior. 👑

and that's the tea, bestie 💅 — this page came from ./net/llc, dated October 2026, and yeah it's llc_ui_create(9), so you already know. byeee 🦋✨
