ieee80211_bss_get_ie(9)

📦 version 7.3.1, in nixpkgs unstable

✨ ieee80211_bss_get_ie(9) ✨

okay so this is a page from the Kernel API Manual, and honestly bestie, it's a short one but it's important. we're looking at ieee80211_bss_get_ie — say that five times fast, i dare you 💅

🌸 NAME 🌸

ieee80211_bss_get_ie — find IE with given ID

like, it goes looking for an information element and hands it back to you. iconic behavior fr fr 🎀

🦋 SYNOPSIS 🦋

const u8 * ieee80211_bss_get_ie (struct cfg80211_bss *bss , u8 id );

that's the whole vibe. it takes a bss and an id, and gives you back a const u8 *. slay ✨

🎀 ARGUMENTS 🎀

  • bss — the bss to search 👀 like, this is the thing you're digging through
  • id — the element ID 💖 the specific IE you're looking for

💜 DESCRIPTION 💜

okay so real talk, bestie — the return value is an RCU-protected pointer. that means rcu_read_lock must be held when calling this function. no cap, this is not optional. hold the lock or else 😭🔒

⚠️ literally do not skip the rcu_read_lock. the pointer is RCU-protected, so the lock needs to be held when you call this function. periodt.

🌈 RETURN 🌈

NULL if not found 🫶

like, if the IE isn't there, you get NULL. that's it. that's the whole return situation. 💀
