cfg80211_upd...e_info_event(9)

✨ cfg80211_upd...e_info_event(9) ✨

okay so real talk, this one lives in the Kernel API Manual (yes, the big serious kernel docs, but we're making it cute today) and it's literally about telling user space that a peer's OWE info changed. bestie, let me break it down 💅

🌸 NAME 🌸

cfg80211_update_owe_info_event — the function that notifies user space about the peer's OWE info 🦋

Like, its whole job is: "hey user space, heads up, the OWE info for this peer is new, come get it" ✨

🎀 SYNOPSIS 🎀

void cfg80211_update_owe_info_event (struct net_device *netdev , struct
cfg80211_update_owe_info *owe_info , gfp_t gfp );

no return value, it's a void function — it just does the thing and dips 😌 periodt.

💖 ARGUMENTS 💖

netdev — the network device 👑 this is the interface the whole vibe is happening on, fr fr.
owe_info — the peer's OWE info 💫 like, the actual data payload of the notification. this is the tea being delivered to user space.
gfp — allocation flags 🌈 the classic kernel memory-allocation flags, so you can tell it how it's allowed to allocate while doing its thing. iykyk.

ngl, that's just part 1 bestie — there's more coming, don't go anywhere 💜

✨ SEE ALSO ✨

okay bestie, buckle up — this page has so many friends, and I'm gonna introduce every single one of them. no skipping, no "you get the idea", we're doing the whole list 💅 (it's a long one, but they're all literally listed in the original, so we're listing them all).

🌱 where it all lives

First up, everything below lives in the kernel file ./include/net/cfg80211.h, and it kicks off with these two:
