cfg80211_rx_mgmt_ext(9)

📦 version 7.3.1, in nixpkgs unstable

✨ cfg80211_rx_mgmt_ext — the kernel API manual, part 1 ✨

okay so this is cfg80211_rx_mgmt_ext(9) from the Kernel API Manual, and bestie, we're doing this in three parts, so buckle up 🎀

💖 NAME 💖

cfg80211_rx_mgmt_ext — management frame notification, but make it extended info ✨

🦋 SYNOPSIS 🦋

bool cfg80211_rx_mgmt_ext (struct wireless_dev *wdev , struct
       cfg80211_rx_info *info );

literally that's the whole signature. bool in, bool out. slay 💅

🌸 ARGUMENTS 🌸

  • wdev — the wireless device that's receiving the frame 🫶 like, the one catching it
  • info — the RX info, as defined in struct cfg80211_rx_info ✨ that's the struct, no cap, exactly that name

🧚 DESCRIPTION 🧚

okay so here's the vibe: this function gets called whenever an Action frame is received for a station mode interface — but only when that frame is not processed in kernel. so the kernel looked at it and was like "not mine, not touching it" and this is the notification that goes out 📣

it's giving "hand it off" energy. main character energy for user space, honestly 👑

ngl the "not processed in kernel" part is the whole point — if the kernel already handled it, this function isn't the one ringing your phone 💀

⭐ RETURN ⭐

  • true — a user space application has registered for this frame 🎉 and for action frames, that means user space is now the one responsible for rejecting unrecognized action frames. it's their problem now, they signed up for it 💅
  • false — otherwise 🙈 and in this case, for action frames, the driver is responsible for rejecting the frame. yes, the driver. not user space. the driver. keep that straight, it matters 🔥

more parts coming, don't go anywhere 🦋

👀 SEE ALSO 👀

okay bestie, this is the part where the man page opens the whole cfg80211 extended universe and says “pick a tab, any tab” 💖. every single cross-reference is down below, same names, same (9) energy, no cap. it’s giving “my brain has 400 tabs open and they’re all slaying.” take a breath, scroll slow, and remember: nothing got cut, not even the tiny underscore guys 🫶.

okay that's the first chunk of the friend list 💅 keep scrolling, there's more, obviously.

the colour-change girlies stay booked and busy, we love that for them 🎀

and that's the whole circle, bestie — 65 entries, tappin' in from every corner of the wifi-adjacent universe 🌈 lowkey iconic that a single SEE ALSO can hold that many people. go read them fr fr, they're all in section 9 and they all deserve a little moment. ✨

and that's a wrap on the whole page, omg 🫶 three parts, zero details lost, main character energy throughout. it comes to you from the source file ./include/net, dated October 2026, and the page itself answers to cfg80211_rx_mgmt_ext(9). take care of her, she's been through a lot of header files 💜🎀 bye bestie, go parse some management frames for me 😭🌸
