netlbl_enabled(9)

💅 NAME

netlbl_enabled — the little vibe check that tells you whether the NetLabel subsystem is, like, actually on ✨

(oh and btw this whole page lives in the Kernel API Manual, section 9, bestie 🎀)

---

🦋 SYNOPSIS

int netlbl_enabled (void );

---

🌸 ARGUMENTS

• void — literally nothing, bestie. no arguments. it takes zero (0) inputs and it is thriving about it 🙈

---

✨ DESCRIPTION

okay so here's the tea ☕ — the LSM can call this function to figure out whether it should be using NetLabel security attributes in its enforcement mechanism. that's the whole job. she's a yes/no girlie.

and how does NetLabel decide? currently, NetLabel is considered enabled when its configuration contains a valid setup for at least one labeled protocol — iykyk, that means NetLabel can understand incoming labeled packets of at least one type 💅. otherwise? NetLabel is considered disabled. periodt. no in-between, no "it's complicated" — just enabled or not.
