cfg80211_unlink_bss(9)

📦 version 7.3.1, in nixpkgs unstable

okay so bestie, welcome to the cfg80211_unlink_bss page — it's short, it's sweet, and it's about yeeting a BSS out of the kernel's little internal bookkeeping ✨

🌸 NAME 🌸

cfg80211_unlink_bss — unlink a BSS from the internal data structures, no cap 🫶

✨ SYNOPSIS ✨

void cfg80211_unlink_bss (struct wiphy *wiphy , struct cfg80211_bss *bss
);

literally that's the whole signature, she's not complicated 💅

🎀 ARGUMENTS 🎀

  • wiphy — the wiphy, aka the wireless device thingy you're working with 📡
  • bss — the bss you wanna remove, bestie. that's the one getting unlinked 👋

🦋 DESCRIPTION 🦋

so what does this function actually do? it removes the given BSS from the internal data structures, which means it no longer shows up in scan results and all that good stuff. gone. not in the list. bye bestie 💀

use this function when you detect that a BSS is gone — like, you looked around and she's not there anymore 🔍

lowkey important note: normally BSSes will also time out on their own, so honestly it is not necessary to use this function at all. like, the kernel will handle it. this is just for when you know and you wanna be proactive about it 🧚

that's the whole vibe for part 1 — more coming, don't go anywhere 🍓

🫶 SEE ALSO — the whole friend group 💅

okay bestie, this is the part where the page just... lists everyone it knows 😭 and it knows a lot of people. like, this is the extended guest list, no cap. every single one of these is a real (9) page you can go read, so let's go through them section by section, yeah? ✨
