💅 llc_ui_ioctl — the Kernel API Manual moment 🎀

okay so bestie, we're in the Kernel API Manual today and the star of the show is llc_ui_ioctl(9). she's giving lowkey legend energy, she's the one who handles the io controls, and honestly? iconic. let's get into it ✨

🌸 NAME 🌸

llc_ui_ioctl — io controls for PF_LLC

like, that's her whole job. io controls. for PF_LLC. periodt. 💅

✨ SYNOPSIS ✨

int llc_ui_ioctl (struct socket *sock , unsigned int cmd , unsigned long arg );

three params, one function, zero mess. she said "keep it clean" and honestly she ate 🫶

🎀 ARGUMENTS 🎀

  • sock — the socket you're getting/setting info on. this is the main character fr, everything happens through her 🌈
  • cmd — the command. the literal instruction. the "what are we doing today" of it all 💫
  • arg — optional argument for cmd. she's optional!! she's just there if cmd needs her 🦋

💖 DESCRIPTION 💖

get/set info on llc sockets.

that's it. that's the whole description. get the info, set the info, live your truth. no cap, sometimes the documentation is short and sweet and we respect that 🍓

👑 SEE ALSO 👑

bestie, the whole squad showed up, and we're starting with the Kernel file ./net/llc/af_llc.c — that's the source, go say hi 💜

then, in the order she lists them (we do not shuffle the lineup, that would be disrespectful):

that's nineteen friends plus the file. a whole friend group. a whole vibe. iykyk 😭🔥

ok real talk — this page is short, but short does not mean skippable. every one of those SEE ALSO entries is a real page, so go read them if you need the lore. no invented facts, no guessing, just vibes and accurate references 🧚

kisses and bye-byes from the ./net/llc directory, dated October 2026, page llc_ui_ioctl(9) — she's serving, she's documented, she's done 💅✨🎀
