cfg80211_report_obss_beacon(9)

📦 version 7.3.1, in nixpkgs unstable

💫 cfg80211_report_obss_beacon(9) 💫

okay so bestie, this one is straight out of the Kernel API Manual and it's giving "hey kernel, I saw a beacon, pls tell userspace" energy. it's a void function, so like… no returns, no drama, no notes. 🎀

✨ NAME ✨

cfg80211_report_obss_beacon — report a beacon that came from other APs 👀 (yes, the ones that aren't you, the whole point)

🦋 SYNOPSIS 🦋

void cfg80211_report_obss_beacon (struct wiphy *wiphy , const u8 *frame
, size_t len , int freq , int sig_dbm );

that's the whole signature, copy it exactly, no cap. 💅

🌸 ARGUMENTS 🌸

  • wiphy — the wiphy that received the beacon. like, whose radio caught it. 🫶
  • frame — the frame. that's it, that's the whole description, the frame itself. 💀
  • len — length of the frame. how many bytes of frame you're handing over.
  • freq — the frequency the frame was received on. 📡
  • sig_dbm — signal strength in dBm, or 0 if unknown. so if you don't know, just put 0, it's fine, nobody's judging. 🙈

🔥 DESCRIPTION 🔥

Use this function to report to userspace when a beacon was received. 📨 that's literally its whole job — beacon shows up, you tell userspace, everyone stays informed, iconic behaviour honestly.

⚠️ okay but listen: it is not useful to call this when there is no netdev that is in AP/GO mode. so if you've got no netdev running as an AP or GO, this call is lowkey pointless — vibe check your setup first, bestie. 🧚

more parts coming, don't go anywhere 💖

👀 SEE ALSO ✨

Okay bestie, real talk: this bit is literally just the cross-reference dump for the whole cfg80211 universe, and it is long. But every single one of these pages is listed below, in order, no skips, no "lol you get the idea". Ngl it's giving "phone book but make it wireless". Obsessed anyway 💅

🌸 and now we enter the configuration era, hold my iced coffee 🌸

💜 utility corner, aka the little helpers that ate 💜

🧚 regulatory section, she's rules and she knows it 🧚

🌈 rfkill, vendor stuff, test mode, and then a frankly unhinged number of notify functions 🌈

Heads up bestie: that last stretch is the whole tail end of the list in the exact order it was given, so if you're grepping, everything after cfg80211_probe_status(9) is exactly those three and then it's done ✨

And… yeah, that's the entire SEE ALSO. Still with me? 🫶 There's more coming, so don't go anywhere 💖

Okay bestie, the cross-reference list keeps going — grab a snack, this is the long tail of the SEE ALSO section and we're reading it all ✨

That's the whole list, bestie. Sixty-three references, zero skipped, and honestly? Ate. 💅

And for the cute sign-off — the little footer that lives at the bottom of the page: this one's sourced out of ./include/net, dated October 2026, and it's filed under the manual page title cfg80211_report_obss_beacon(9). So like, when you cite it, cite it correctly 🫶 Go be great with your beacons, bestie — you've got this fr fr 💖
