ieee80211_pspoll_get(9)

📦 version 7.3.1, in nixpkgs unstable

💖 ieee80211_pspoll_get(9) — from the Kernel API Manual, bestie 🎀

okay so picture this: you're deep in the kernel, it's giving driver-dev main character energy, and you need a PS Poll template. That's literally what this lil function hands you. Let's get into it ✨

✨ NAME ✨

ieee80211_pspoll_get — retrieve a PS Poll template 🦋

🌸 SYNOPSIS 🌸

struct sk_buff * ieee80211_pspoll_get (struct ieee80211_hw *hw , struct
ieee80211_vif *vif );

Like, that's the whole vibe. Two args in, one sk_buff * out 💅

🎀 ARGUMENTS 🎀

  • hw — a pointer you got from ieee80211_alloc_hw. Yep, that one. The hardware handle, the whole reason you're here 🫶
  • vif — a struct ieee80211_vif pointer, the kind you get handed in the add_interface callback. It's giving "the interface in question" ⭐

💜 DESCRIPTION 💜

So what it does: it creates a PS Poll, a template, which can (for example!) be uploaded to hardware. That's the flex 🔥

Here's the part you cannot skip tho — the template must be updated after association so that the correct AID, BSSID and MAC address is used. Not me stressing about stale templates 😭 Like bestie, if you don't refresh it post-association you're gonna be sending the wrong identity out there. No cap.

💀 NOTE 💀

Heads up! The caller (or the hardware) is responsible for setting the IEEE80211_FCTL_PM bit. That's not on this function. That's on you, queen 👑 Don't forget it.

🌈 RETURN 🌈

Returns the PS Poll template. And on error? NULL. That's it, that's the whole story 🙈
