netlbl_unlabel_init(9)

💅 netlbl_unlabel_init(9): a Kernel API Manual moment 💅

okay so welcome to the Kernel API Manual page for netlbl_unlabel_init, bestie. This is the init function that sets up the unlabeled connection hash table and gets a network device notification handler registered. It is literally giving “NetLabel subsystem setup era,” not “call me from anywhere” energy. ✨

🌸 NAME 🌸

netlbl_unlabel_init — Initialize the unlabeled connection hash table.

✨ SYNOPSIS ✨

int netlbl_unlabel_init (u32 size );

🎀 ARGUMENTS 🎀

• size — the number of bits to use for the hash buckets. That’s the whole arg, bestie; it is the number of bits to use for the hash buckets. 💖

🦋 DESCRIPTION 🦋

Okay so what it does: it initializes the unlabeled connection hash table and registers a network device notification handler. Two jobs, both iconic. ✨

Important caveat, no cap: this function should only be called by the NetLabel subsystem itself during initialization. It is not a random-caller invitation. 🙈

Return vibes: it returns zero on success, and non-zero values on error. So zero = success slay, non-zero = error situation. 💅
