bestie 💖 you just opened sel_netnode_sid_slow(9) from the Kernel API Manual, and we’re gonna make it make sense. no cap.

✨ NAME ✨

sel_netnode_sid_slow — Lookup the SID of a network address using the policy.

🌸 SYNOPSIS 🌸

int sel_netnode_sid_slow (const void *addr , u16 family , u32 *sid );

🎀 ARGUMENTS 🎀

• addr — the IP address. that’s the address, bestie 📍
• family — the address family. family vibe check 👑
• sid — node SID. the node SID, periodt.

🦋 DESCRIPTION 🦋

okay so here’s the whole vibe: sel_netnode_sid_slow determines the SID of a network address by querying the security policy. then the result is added to the network address table to speedup future queries. returns 0 on success, negative values on failure. literally that’s the tea ☕
