✨ sel_ib_pkey_sid_slow(9) ✨

okay so this is a page from the Kernel API Manual bestie, and it's literally all about sel_ib_pkey_sid_slow — the slow-but-steady lookup queen 👑. yes the name has "slow" in it, she's aware, she's owning it 💅

💖 NAME 💖

sel_ib_pkey_sid_slow — Lookup the SID of a pkey using the policy 🎀

---

🦋 SYNOPSIS 🦋

int sel_ib_pkey_sid_slow (u64 subnet_prefix , u16 pkey_num , u32 *sid );

yep that's the whole signature, spaces and all, no cap ✨

---

🌸 ARGUMENTS 🌸

• subnet_prefix — the subnet prefix, that's her whole job 🫶
• pkey_num — the pkey number, iconic little number that it is ⭐
• sid — the pkey SID 🔥

---

🌈 DESCRIPTION 🌈

so what does she actually do? this function determines the SID of a pkey by querying the security policy 🔍 — like, she goes and asks the policy directly, main character energy.

then the result gets added to the pkey table so future queries are speedier 💨 (that's the whole reason she's called "slow" — she does the expensive lookup once so everyone else can vibe later).

returns zero on success 🎉, negative values on failure 😭 — so like, check your return value fr fr.
