💅 cfg80211_nan_func_terminated(9) — kernel API manual, but make it make sense

okay so this is cfg80211_nan_func_terminated, straight out of the kernel API manual, and bestie it is exactly what it sounds like: it's the little messenger that goes "hey, that NAN function? yeah, it's done. terminated. gone. 💀" No cap.

✨ NAME ✨

cfg80211_nan_func_terminated — notify about NAN function termination. that's the whole job. it reports the ending. the finale. the last episode. 🎬

🦋 SYNOPSIS 🦋

void cfg80211_nan_func_terminated (struct wireless_dev *wdev , u8
       inst_id , enum nl80211_nan_func_term_reason reason , u64 cookie , gfp_t
       gfp );

it returns void, meaning it hands you nothing back — it's giving generous, it's giving "the reward is the friends we made along the way". 🫶

🎀 ARGUMENTS 🎀

  • wdev — the wireless device reporting the match. yeah, this is the one spilling the tea. 📢
  • inst_id — the local instance id. it's the u8 lil' name tag so everyone knows which instance we're talking about.
  • reason — termination reason, and it's gotta be one of the NL80211_NAN_FUNC_TERM_REASON_* values. no homemade reasons, no vibes-based reasons, only the canon list. 👑
  • reason... jk not twice — cookie — unique NAN function identifier. it's literally the function's main character ID. 🍪
  • gfp — allocation flags. the classic gfp_t moment, because the kernel always needs to know how you want your memory served. 🌸

💜 DESCRIPTION 💜

so what does it actually do? simple, iconique: this function reports that a NAN function is terminated. that's it. that's the whole plot. it's the "we need to talk" text but for a NAN function's lifecycle. ✨

lowkey important: it's a report. it's announcing the termination, not doing the dramatic breaking-up for you. don't come for me, that's literally what the page says. 🙈

more parts coming, don't go anywhere bestie 🌈

👀 SEE ALSO 👀

okay bestie, this is the part where the page just... lists everything. and i mean everything. it's giving "the author found every single symbol in the header and went 'yes, all of them'". no cap, it's a whole vibe. here's the complete list, in the exact order it's given, nothing cut 🫶

  • the kernel file itself: ./include/net/cfg80211.h — and Introduction(9) to hold your hand through it

🌸 the header intro & the band/capability era 🦋

lowercase _ieee80211_set_sband_iftype_data(9) sitting right next to the regular one — that's the internal twin, bestie. they really said "you get both versions" 💅

💅 the wiphy life cycle era 🫶

look at all those wiphy_*_work_* and wiphy_hrtimer_work_* pairs — queue, cancel, flush, pending, four times over. they really said "consistency is free, do it for everything" 😭💀

🧚 Utility functions 🍓

⭐ Data path helpers 💜

🌸 Regulatory enforcement infrastructure 👑

note the difference between regulatory_set_wiphy_regd(9) and regulatory_set_wiphy_regd_sync(9) — one's got the _sync glow-up, iykyk 💅

🔥 scan/BSS notifications, MLME & friends 🌈

the __-prefixed __cfg80211_get_bss(9) is the lowkey twin of cfg80211_get_bss(9), it's giving internal-helper energy 🙈

🎀 RFkill integration, Vendor commands, Test mode 🎀

💀 connect / roam / disconnect notifications 😭

🌟 rx/tx mgmt, control port, CQM, radar etc. 🦋

aaaaand that's the entire SEE ALSO list, every single one, nothing skipped 💖 and yeah the page keeps going after this so don't you dare close the tab yet, bestie 👀💅

...and the rest of the extended fam, bestie — the whole group chat is here, no one got left on read 💅

That's the whole roster — 63 cross-refs, not one dropped, because we don't do incomplete lists in this house 💖

And that's a wrap on the whole page, bestie 🎀 This iteration came straight out of ./include/net, dated October 2026 — so go forth, register your netdevices, free your NAN funcs, and stay slay ✨👑
