cfg80211_pm...idate_notify(9)

📦 version 7.3.1, in nixpkgs unstable

👑 cfg80211_pmksa_candidate_notify — like, the whole cfg80211_pm...idate_notify(9) situation

okay bestie, buckle up 💅 this one's from the Kernel API Manual, and it's literally the glow-up of kernel wireless docs. no cap.

✨ NAME ✨

cfg80211_pmksa_candidate_notify — notify about PMKSA caching candidate 🫶

🌸 SYNOPSIS 🌸

void cfg80211_pmksa_candidate_notify (struct net_device *dev , int index
, const u8 *bssid , bool preauth , gfp_t gfp );

like, that's the whole signature. iconic, lowkey. ⭐

🦋 ARGUMENTS 🦋

so here's the cast of characters, and they ALL matter, okay? 🙈

  • dev — network device. that's the main character right there 👑
  • index — candidate index. ngl, the smaller the index, the higher the priority 💖 like the front of the line at a concert, fr fr
  • bssid — BSSID of AP. the actual address of the access point, periodt 🌈
  • preauth — whether the AP advertises support for RSN pre-authentication. yes, that's a real long word and yes, it means what it says ✨
  • gfp — allocation flags. the ~vibes~ of how we're allowed to allocate memory 🎀

okay that's part one, there's more coming so don't go anywhere, bestie 💜🧚
