tipc_sk_mcast_rcv(9)

💅 tipc_sk_mcast_rcv(9) — like, the kernel API manual edition, bestie 🎀

okay so this is a page from the Kernel API Manual, and it's about one very specific little function that has one very specific job. no cap. let's get into it ✨

---

🌸 NAME 🌸

tipc_sk_mcast_rcv — delivers multicast messages to all the destination sockets 🫶 (yes, all of them. every single one. iconic behaviour honestly)

---

✨ SYNOPSIS ✨

void tipc_sk_mcast_rcv (struct net *net , struct sk_buff_head *arrvq ,
       struct sk_buff_head *inputq );

that's it. that's the whole signature. three args, void return, no notes 💅

---

🦋 ARGUMENTS 🦋

• net — the associated network namespace. it's giving "whose little world are we in" energy 🌍
• arrvq — the queue with the arriving messages. these babies get cloned after the destination lookup happens 👯
• inputq — the queue with the cloned messages. these get delivered to the socket after the destination lookup 🎁

---

💜 DESCRIPTION 💜

Multi-threaded: parallel calls that reference the same queues may occur 😭

fr fr bestie, read that again. multiple threads can be in here at the same time pointing at the same queues, and that is a whole vibe check you need to be aware of before you go touching anything. no cap.

and that's the page, bestie!! stay hydrated, clone responsibly, and remember: multi-threaded means share the queues, not your secrets 🧚💖
