rdma_create_id(9)

📦 version 7.3.1, in nixpkgs unstable

💖 rdma_create_id(9) 💖

okay so bestie, welcome to rdma_create_id(9) from the Kernel API Manual — yes that manual, the one your kernel-dev crush keeps quoting. this is literally the page that spawns RDMA identifiers, and no cap, it's kind of a big deal 🎀

✨ SYNOPSIS ✨

rdma_create_id (net , event_handler , context , ps , qp_type );

like, yes, the spacing before the parens is iconic and we're keeping it exactly as-is, don't @ me 💅

🌸 ARGUMENTS 🌸

  • net — the network namespace where your shiny new id gets created. that's the whole vibe, it's home base 🏠
  • event_handler — the user callback that gets invoked to report events tied to the rdma_id you get back. it's the main character of the whole operation, honestly 🔥
  • context — a user-specified context that gets associated with the id. your little souvenir to bring along 🎀
  • ps — RDMA port space. that's it, that's the whole description, keep it moving 🦋
  • qp_type — the type of queue pair that goes with the id. the qp's whole personality, basically 👑

💜 DESCRIPTION 💜

so this bad boy returns a new rdma_cm_id. iconic. and here's the tea: the id holds a reference on the network namespace until it is destroyed — so like, it's not letting go of that namespace until you properly destroy it, fr fr. don't leave it hanging 😭

and the event handler callback? it serializes on the id's mutex and — good news — it is allowed to sleep. yes bestie, you read that right, sleeping is permitted, we love a callback that gets its rest 😴✨
