💖 llc_establish_connection(9) 💖

okay so this is a page from the Kernel API Manual, section 9 — yes bestie, the big kernel one. sit down, grab a boba, we're learning kernel networking 🧚✨

---

🌸 NAME 🌸

llc_establish_connection — the function your upper layer calls when it wants to ~establish a conn~ 🫶

---

✨ SYNOPSIS ✨

int llc_establish_connection (struct sock *sk , const u8 *lmac , u8
*dmac , u8 dsap );

like, it returns an int, it's got four args, and yes the line break in the middle of u8 *dmac is literally how it's printed, we don't question the manpage typography 💅

---

🎀 ARGUMENTS 🎀

• sk — the connection 🦋 (that's it, that's the description, she's a struct sock * and she's the connection)
• lmac — local mac address 📍 (a const u8 *, so hands off)
• dmac — destination mac address 🎯
• dsap — destination sap 🔖

---

👑 DESCRIPTION 👑

so the upper layer calls this function when it wants to establish an LLC connection with a remote machine 🌈. that's the whole vibe.

what it actually does: this function packages a proper event and sends it to the connection component state machine 📦➡️🧠. very main character of it.

and when the connection establishment either succeeds or fails, that info gets passed back up to the upper layer — by calling its confirm function and passing the proper information along 💌. so you're never left on read, periodt.
