💅 cfg80211_testmode_reply(9) 💅

ok so picture this: you're deep in the Kernel API Manual (that's the manual name bestie, we're in the kernel docs rn 🌸) and you just need to send your reply. That's literally what this whole page is about. Let's get into it ✨

🎀 NAME 🎀

cfg80211_testmode_reply — it sends the reply skb, no cap, that's the whole job 💌

🦋 SYNOPSIS 🦋

int cfg80211_testmode_reply (struct sk_buff *skb );

one function, one argument, immaculate vibes 👑

🌸 ARGUMENTS 🌸

  • skb — the skb itself, bestie. And listen, it must have been allocated with cfg80211_testmode_alloc_reply_skb. That's not optional, that's the rule. If you roll up with some random skb you made yourself, that's not it 🙈

💖 DESCRIPTION 💖

So the way this works: calling this function is usually gonna be the last thing you do before you return from the testmode_cmd, which means the move here is to return the error code — like, you already know what happened, so hand it back. main character behavior honestly 💅

🫶 important one: this function consumes the skb regardless of the return value. Read that again. Success or error, the skb is gone. Do not touch it after. Do not pass it somewhere else. She's been taken, and she's not coming back 😭

⭐ RETURN ⭐

You get an error code back, or 0 on success. That's it, that's the whole return story 🎀

anyway bestie this is just part 1, so don't go anywhere — there's more coming and I'm not done hyping you up yet 🔥

🎀 SEE ALSO 🎀

okay the reference list literally keeps going and every single one of these is a baddie in her own right — here's the rest of the SEE ALSO crew, and yes you should read them all, bestie, no cap:

okay that's genuinely the whole list, you made it, I'm so proud of you 🥹💖 go read a few of them, pick your faves, iykyk.

this little love letter lives at ./include/net, dated October 2026, and it's the cfg80211_testmode_reply(9) page — go be iconic with it, bestie, and remember: check your return values 💅✨🦋
