cfg80211_rx_spurious_frame(9)

💅 cfg80211_rx_spurious_frame — Kernel API Manual

okay so bestie, buckle up, we're in the Kernel API Manual today and this one's about telling userspace that a frame showed up out of nowhere. iconic behaviour, honestly 🎀

---

✨ NAME ✨

cfg80211_rx_spurious_frame — inform userspace about a spurious frame

---

🦋 SYNOPSIS 🦋

bool cfg80211_rx_spurious_frame (struct net_device *dev , const u8 *addr
, int link_id , gfp_t gfp );

---

🌸 ARGUMENTS 🌸

• dev — the device the frame matched to 👑
• addr — the transmitter address, i.e. who sent this thing
• link_id — the link the frame was received on; it's -1 if that's not applicable or it's just... unknown 🙈
• gfp — context flags, the usual allocation-vibes situation

---

💖 DESCRIPTION 💖

so this function is the one you call in AP mode to let userspace know a spurious class 3 frame got received — the whole point being so userspace can deauth the sender 😭 like, bye.

it also gets used in NAN_DATA mode to report frames coming from unknown peers (specifically: A2 not assigned to any active NDP), and that's per the Wi-Fi Aware (TM) 4.0 specification 6.2.5 — yes she cited her sources, periodt 📚✨

---

🔥 RETURN 🔥

true if the frame was passed to userspace — or if this whole thing failed for a reason other than not having a subscription. yep, read that twice, it's giving "technically a win" 💀

---

more parts coming, don't go anywhere 🫶

okay bestie, buckle up — this SEE ALSO section is a whole family reunion 👑💖 it's giving "everyone in cfg80211 showed up and brought a plus-one," and I kept every single reference in the exact order, no skips, no cap:
