💅 cfg80211_iftype_allowed(9) — Kernel API Manual

okay bestie, welcome to cfg80211_iftype_allowed, straight out of the Kernel API Manual ✨ this one's a vibe check for wireless interfaces, iykyk 🦋

🌸 NAME 🌸

cfg80211_iftype_allowed — check whether the interface can be allowed 🎀

✨ SYNOPSIS ✨

bool cfg80211_iftype_allowed (struct wiphy *wiphy , enum nl80211_iftype
iftype , bool is_4addr , u8 check_swif );

like, that's the whole signature, no cap 💜

🫶 ARGUMENTS 🫶

  • wiphy — the wiphy, that's it, that's the whole description, it's giving minimalistic icon behavior 👑
  • iftype — the interface type 🌈
  • is_4addr — the use_4addr flag, and heads up bestie: this one must be '0' when check_swif is '1' — that's not a suggestion, that's the rules fr fr ⚠️
  • check_swif — check iftype against software interfaces 🧚

💖 DESCRIPTION 💖

So basically this API checks whether the interface is allowed to operate — like, is it permitted to even do its little thing, yes or no 💅

And on top of that? It can also be used to check iftype against the software interfaces when check_swif is '1'. Two jobs, one function, main character energy ⭐

🔥 RETURN 🔥

true if allowed, false otherwise — binary queen, she doesn't do maybes 🙈

✨ SEE ALSO ✨

okay bestie, this is the part where the man page just... introduces you to everyone 💅 no cap, this is the whole extended friend group, and honestly it's giving graduation ceremony energy — everybody gets their name called, nobody gets skipped. I'm putting them in the exact same order, so you can scroll and vibe-check any of them 💖

Okay bestie, buckle up, because the SEE ALSO list on this page is long — it's giving "the whole friend group showed up to your party" energy. Every single one of these is a real page you can go read next, fr fr:

Like… SIXTY-THREE of them. And yes, two of them are structs chilling in a SEE ALSO list like they own the place (struct cfg80211_ft_event_params(9) and struct cfg80211_nan_match_params(9), I see you 👀). That's not a typo, that's just how it is — keep the names exactly as written and you'll be golden. Do not try to "clean up" the list, bestie, it's perfect as it is 💅

And that's the whole page!! 🎀✨ You made it to the end, I'm literally so proud of you 🫶 The version and date info lives in the footer — this one's from the ./include/net source, dated October 2026, for the page cfg80211_iftype_allowed(9) — and now you know all of it. Go forth and slay, mwah 💖
