💖 ieee80211_iterate_stations_atomic 💖

okay so bestie, this is a page from the Kernel API Manual (mac80211 land, section 9) and it's genuinely one of the shorter ones so we're gonna get through it together, hand in hand 🫶

✨ NAME ✨

ieee80211_iterate_stations_atomic — literally just iterate stations 💅 that's the whole thing. the name ate and left no crumbs.

🌸 SYNOPSIS 🌸

void ieee80211_iterate_stations_atomic (struct ieee80211_hw *hw , void
(*iterator)(void *data, struct ieee80211_sta *sta) , void *data );

look at her. three args, one function pointer, zero chill. 🎀

🦋 ARGUMENTS 🦋

  • hw — the hardware struct of which the interfaces should be iterated over. yeah, we're going over its interfaces. it's giving main character hardware energy 👑
  • iterator — the iterator function to call. cannot sleep 😴🚫 not "shouldn't", cannot — like, do not. no cap, this is the whole vibe check of this function.
  • data — first argument of the iterator function. you hand it a thing, the callback gets that thing. that's the pipeline, bestie 🍓

🔥 DESCRIPTION 🔥

So here's the tea ☕: this function iterates over all stations associated with a given hardware that are currently uploaded to the driver and calls the callback function for them.

Read that again — currently uploaded to the driver. Not the theoretical stations in the sky. The ones that are actually there right now. 🌈

And the big one: this function requires the iterator callback function to be atomic.

⚠️ lowkey important: atomic means atomic. your callback cannot sleep. if it tries to nap, that's not a vibe check failing, that's your kernel having a bad time 💀

🧚 SEE ALSO 🧚

okay bestie this list is long long — like genuinely iconic levels of cross-referencing. but you asked, and I would never gatekeep. every single one, in order, no cap 💜

Kernel file ./include/net/mac80211.h

like… that's the whole friend group right there 😭 every single one showed up to the party 🎉

okay that's the page bestie!! 💅✨ this little gem lives in ./include/net and it's dated October 2026 — so yeah, fresh off the press, no cap 🎀 go forth and iterate atomically, and remember: your callback does not sleep 👑💖
