netlbl_catmap_walk(9)

✨ NAME ✨

Bestie, welcome to netlbl_catmap_walk(9) from the Kernel API Manual 🫶 This page is literally about netlbl_catmap_walk: walking a LSM secattr catmap looking for a bit. No cap, that's the whole assignment. 💅

---

🌸 SYNOPSIS 🌸

The signature is giving exactly this, character for character:

int netlbl_catmap_walk (struct netlbl_lsm_catmap *catmap , u32 offset );

---

🎀 ARGUMENTS 🎀

• catmap — the category bitmap. Yep, that's the bitmap bestie; it's the thing being walked. 🦋
• offset — the offset to start searching at, in bits. Like, where the search begins, fr fr. ⭐

---

💖 DESCRIPTION 💖

Okay so this function walks a LSM secattr category bitmap starting at offset, and it returns the spot of the first set bit. If no bits are set, it returns -ENOENT. That's it — iconic behavior, honestly. 😭

Lowkey important: -ENOENT is the no-bits-set outcome. Don't forget it. 🫶
