llc_conn_reset(9)

🦋 llc_conn_reset — bestie's guide to hitting the reset button 🎀

okay so first things first, we're in the Kernel API Manual section 9 today, and the star of the show is llc_conn_reset. yes, the little function that could. the way she just... wipes the slate clean? genuinely iconic behavior. periodt. 💅

✨ NAME ✨

llc_conn_reset — resets connection ✨

like. she resets the connection. that's the whole vibe. no notes. 🫶

🌸 SYNOPSIS 🌸

int llc_conn_reset (struct sock *sk , struct sk_buff *skb );

yes bestie, that's the signature, copied exactly, spaces and all, do not touch, we do not edit the kernel here 😭

🧚 ARGUMENTS 🧚

• sk — the connection that's getting reset 💫 (the original page spells it reseting and honestly? we stan a typo queen. she means resetting. we know. 🎀)
• skb — the event that occurred 🔥 like, the thing that happened and triggered all this drama in the first place

👑 DESCRIPTION 👑

okay so literally what she does is three things and she does them fabulously:

1. Stop all timers ⏰ — all of them. every single one. they're done, they're going home, it's over.
2. Empty all queues 🗑️ — nothing left in there, we cleared it out, it's giving fresh-start energy.
3. Reset all flags 🚩 — every flag. back to default. the drama is cancelled.

that's it. that's the function. lowkey the most satisfying three-for-one in the whole file, ngl. 🌈

bestie heads up — this is the full reset, so everything above happens, no half measures, no "just one timer", it's all of it. 💖
