💅 ieee80211_ap_probereq_get(9) 💅

okay bestie, so this one is straight out of the Kernel API Manual and it's literally the cheat code for grabbing a Probe Request template without building one by hand. it's giving "small function, big rules" energy, so let's get into it 🫶

✨ NAME ✨

ieee80211_ap_probereq_get — retrieve a Probe Request template 🎀

🌸 SYNOPSIS 🌸

struct sk_buff * ieee80211_ap_probereq_get (struct ieee80211_hw *hw ,
  struct ieee80211_vif *vif );

🦋 ARGUMENTS 🦋

  • hw — the pointer you got from ieee80211_alloc_hw. yeah, that one. don't lose it, don't invent your own 💀
  • vif — your struct ieee80211_vif pointer, the one that came from the add_interface callback. the main character struct, fr fr 👑

💖 DESCRIPTION 💖

so what this does is creates a Probe Request template — like, an actual ready-to-go frame — which can, for example, be uploaded to hardware. no cap, that's the whole point. 🚀

the template gets filled with bssid, ssid and supported rate information. that's the trio. that's the vibe. ⭐

now here's the part where you actually pay attention, bestie, because there are rules:

⚠️ this function must only be called from within the .bss_info_changed callback function, and only in managed mode. not your random callback, not IBSS, not AP. those exact conditions. the function will not be your friend otherwise. 😭

and one more thing — it's only useful when the interface is associated. if it's not associated, it will return NULL. like, don't be surprised. it told you. 🙈

🌈 RETURN 🌈

  • the Probe Request template. iconic. queen behavior. 💅
  • NULL on error. that's it, that's the deal. 💀

👑 SEE ALSO 👑

okay so this list is long long. like, genuinely a whole wall of cross-references. but i love a thorough queen, so here's every single one, no skips, no cuts, periodt 🎀

and that's the whole thing, bestie!! 🫶 you're now certified in Probe Request template retrieval. go forth and only call it from .bss_info_changed in managed mode, or the kernel will humble you 😭✨
