tipc_nametbl_lookup_anycast(9)

🎀 NAME 🎀

Bestie, welcome to the tipc_nametbl_lookup_anycast(9) page from the Kernel API Manual 💖 — this one does service instance to socket translation, and it’s lowkey iconic.

---

✨ SYNOPSIS ✨

bool tipc_nametbl_lookup_anycast (struct net *net , struct tipc_uaddr
       *ua , struct tipc_socket_addr *sk );

---

🫶 ARGUMENTS 🫶

• net — network namespace 🌐
• ua — service address to look up 🔎
• sk — address to socket we want to find 🧦

---

💅 DESCRIPTION 💅

Okay so on entry, a non-zero sk->node means “hey, do this lookup on the node I’m pointing at” — and bestie, that node may not be this one. 💫

On exit, the vibe check goes like this:

• If lookup is deferred to another node, leave sk->node unchanged and return true ✅
• If lookup is successful, set the sk->node and sk->ref (== portid) which represent the bound socket and return true 🎯
• If lookup fails, return false 💀

Also note: for legacy users (node configured with Z.C.N address format), the we must look in the local binding list first 🫶
