tipc_sk_overlimit2(9)

💅 tipc_sk_overlimit2 — the kernel API manual, bestie edition ✨

okay so picture this: we're deep in the Kernel API Manual (yeah, the tipc_sk_overlimit2(9) one, the sequel nobody saw coming 🎬) and this little function is out here doing a vibe check on your socket's rx queue. iconic behavior, honestly.

---

✨ NAME ✨

tipc_sk_overlimit2 — checks if the socket rx queue is like, about to be overloaded 🫣 and like… only the rcv queue gets considered, no cap. main character energy: one queue, one job.

---

🎀 SYNOPSIS 🎀

bool tipc_sk_overlimit2 (struct sock *sk , struct sk_buff *skb );

like, it takes two things and gives you back a bool. simple. clean. slay 💅

---

🦋 ARGUMENTS 🦋

• sk — the tipc sk that's getting checked, bestie. this is the socket we're side-eyeing 👀
• skb — the tipc msg getting checked too, fr fr. it's coming along for the ride 🚗

---

🔥 RETURN 🔥

returns true if the socket's rx queue allocation is > 90% — like, almost full, we're sweating 😭 — otherwise it's false. that's it, that's the whole answer 💀

ngl, keep an eye on that > 90% threshold, it's literally the entire point of this function 🌸
