ieee80211_is...ublic_action(9)

💖 ieee80211_is_protected_dual_of_public_action(9) 💖

okay so bestie, welcome to the Kernel API Manual page for ieee80211_is_protected_dual_of_public_action — yes that name is a whole mouthful, and yes it ate 💅. This is a little helper living in ./include/linux/ieee80211.h and its entire personality is: "does this skb hold a protected dual of public action management frame?" That's it. That's the whole job. Iconic, honestly.

✨ NAME ✨

ieee80211_is_protected_dual_of_public_action — checks whether the skb contains a protected dual of public action management frame 🦋

---

🌸 SYNOPSIS 🌸

bool ieee80211_is_protected_dual_of_public_action(struct sk_buff *skb);

like, that's the whole signature. short. sweet. does its one thing. main character energy fr fr 🎀

---

💜 ARGUMENTS 💜

• skb — the skb containing the frame, and heads up bestie, the length will be checked 👀 so don't be out here passing something weird and expecting a miracle.

---

🫶 RETURN 🫶

Returns true if the skb contains a protected dual of public action management frame, and false otherwise. literally that simple, no cap 💖

like, that's the whole friend group and they all showed up to the function's birthday party 🌈💀 no one got left off the list, bestie.

pro tip from your girl: the "protected dual of public action" thing is a management frame situation, and the length of the skb really does get checked, so don't skip that part when you're debugging and then come crying to me 😭
