aa_label_alloc(9)

💅 aa_label_alloc(9) — like, the Kernel API Manual page, bestie 🎀

okay so picture this: you're deep in aa_label_alloc, straight out of the Kernel API Manual, and you need a label with a profile vector. let me walk you through it, no cap 🦋

---

✨ NAME ✨

aa_label_alloc — allocate a label with a profile vector of @size length. that's the whole vibe. that's her job. 💖

---

🌸 SYNOPSIS 🌸

struct aa_label * aa_label_alloc (int size , struct aa_proxy *proxy ,
gfp_t gfp );

look at that signature. iconic. it returns a struct aa_label * and it takes three things. slay 💅

---

🦋 ARGUMENTS 🦋

• size — the size of the profile vector in the label. like, how big the vector is gonna be, fr fr 📏
• proxy — the proxy to use OR null if you want it to allocate a new one. your call, bestie 🫶
• gfp — the memory allocation type. this is the flavouring of the allocation, iykyk ✨

---

👑 RETURN 👑

you get a new label back 💖 ... or NULL if it failed 😭 that's it, that's the deal.

no cap, NULL means it did not work out. don't be out here dereferencing that, bestie. 🫶

that's the whole page, bestie 🎀 — it lives in ./security/apparmor, the source line dates it to October 2026, and the footer literally just says the same name again in the manual-page-girlie way: aa_label_alloc(9). byeee, stan AppArmor 🌸💅✨
