🦋 regulatory_p...te_dfs_state(9) — Kernel API Manual 🦋

okay so bestie, welcome to the group chat for regulatory_propagate_dfs_state 💅 this one lives in the Kernel API Manual and honestly? she's a whole vibe. let's get into it ✨

🌸 NAME 🌸

regulatory_propagate_dfs_state — propagates DFS channel state to the other wiphys, no cap 🫶

✨ SYNOPSIS ✨

void regulatory_propagate_dfs_state (struct wiphy *wiphy , struct
cfg80211_chan_def *chandef , enum nl80211_dfs_state dfs_state , enum
nl80211_radar_event event );

like, she takes four things and returns void — she's giving "I don't need to give anything back, my work speaks for itself" energy 👑

🎀 ARGUMENTS 🎀

  • wiphy — the wiphy where the radar got detected 👀 and from there the event gets propagated to the other available wiphys that share the same DFS domain. it's giving "tell your friends" fr fr
  • chandef — the channel definition of the channel where the radar was detected 📡 literally the whole map of the situation
  • dfs_state — the DFS channel state that's about to be set 🦋 the glow-up we're applying
  • event — the type of radar event that triggered this DFS state change 🔥 iykyk, she's the reason we're all here

💖 DESCRIPTION 💖

This function should be called with the rtnl lock held 🔒 like, do NOT skip this, bestie — it's the one rule and we respect it. hold the lock, then call her. periodt 💅

not me stressing the lock thing — but fr fr, hold that rtnl lock before you call this. it's written right there in the manpage and we do not argue with the manpage 🙈

🌈 SEE ALSO 🌈

she's got a whole friend group, and they're all iconic 👑 check the kernel file ./net/wireless/reg.h and also go say hi to:

like, the whole squad showed up to the function 💀 love that for them 🍓

and that's the page, bestie!! 🧚💜 big slay, you read the whole thing. this one's from ./net/wireless, dated October 2026, and it's literally titled regulatory_p...te_dfs_state(9) — she's a little truncated in the name but our hearts know the full truth 💖 mwah, go forth and propagate that DFS state 🌸✨
