cfg80211_free_nan_func(9)

📦 version 7.3.1, in nixpkgs unstable

🌸 cfg80211_free_nan_func 💅

okay so this is a page from the Kernel API Manual, and honestly? it's a short one, so let's get into it bestie 💖

✨ NAME ✨

cfg80211_free_nan_func — free a NAN function 🫶

✨ SYNOPSIS ✨

void cfg80211_free_nan_func (struct cfg80211_nan_func *f );

like, that's the whole call. no return value, no drama, she just goes in and does her thing ✨

✨ ARGUMENTS ✨

  • f — the NAN function that should be freed. that's it, that's the one thing you pass in 🎀

✨ DESCRIPTION ✨

okay so what this does is: it frees all of the NAN function, plus every single allocated member that's hanging off it. not just the top-level struct — the whole little family of allocations underneath it too, all of them, gone 💀

real talk: it's a full cleanup, so nothing allocated inside that struct gets left behind. the way that's the entire job and she ate 🔥

and that's the beginning of this one — there's more coming, so hold that thought 🦋

💫 SEE ALSO 💫

okay bestie, buckle up — this is the part where the manpage just... dumps the entire friend group on you 😭 like not a drill, this is the whole contact list, and yes you're gonna read it. every single one is a (9) page, every single one is real, and every single one is invited to the group chat. no skipping, no scrolling past. i'm holding your hand through it 🫶

first up, the actual file this all lives in:

  • Kernel file ./include/net/cfg80211.h

then the intro crew, the absolute OGs who explain what any of this even is ✨

now the phy/band/channel-flavours squad — this is giving "every single capability flag gets its own page" and honestly? iconic 💅

next: Actions and configuration(9) 👑 which is lowkey a whole lifestyle, and it comes with the chandef family, the beacon/ap settings clan, the station-parameters crew, and the mesh/ocb neighbours. it's giving "one section, forty structs" and we love that for us 🌸

then Scanning and BSS list handling(9) 🦋 — the "who's out there and what are they doing" section, plus the auth/assoc/connect/wowlan/pmsr extended universe. this chunk alone is like a whole season of television, no cap 📺

and then Neighbor Awareness Networking (NAN)(9) 💖 — bestie this is literally the page we're on, so yeah, cfg80211_free_nan_func shows up to its own party through these. the whole NAN cast, plus pmk/external auth/ftm/pmsr/owe:

then the Utility functions(9) corner 🧰 — the little helpers that just do one thing really well, plus the find-the-IE gang and the 8023/data-path friends:

then the Regulatory enforcement infrastructure(9) zone 🗺️ — the "what am I actually allowed to transmit and where" crew, plus the internal regdb functions and the scan-done / inform-bss / get-bss machinery:

RFkill integration(9) 📡 and Vendor commands(9) 🎀 and Test mode(9) 🧪 — yes test mode is real, yes it has four whole pages:

and finally the notification / event / "tell userspace what just happened" besties 🔥 connect, roam, disconnect, mgmt tx status, cqm, cac, station add/remove, control port... the whole gossip pipeline:

💀 and that's the list, bestie. every name, every (9), exactly as the manpage drops it. yep, the kernel really does have a page for all of these.

and that's the whole SEE ALSO bestie, you're officially saturated 💖

this page came from ./include/net, dated October 2026, and it's filed under cfg80211_free_nan_func(9) — go forth and free those NAN funcs, ily, bye 🎀🫶
