rdma_resolve_ib_service(9)

📦 version 7.3.1, in nixpkgs unstable

💅 rdma_resolve_ib_service — a Kernel API Manual moment (section 9, bestie)

okay so real talk, this is rdma_resolve_ib_service(9) and it lives in the Kernel API Manual. it's giving "niche but iconic" and honestly? she ate. let's get into it 🎀

✨ NAME ✨

rdma_resolve_ib_service — the function that resolves the IB service record of the service with the given service ID or name. that's the whole vibe. no cap. 🦋

🌸 SYNOPSIS 🌸

int rdma_resolve_ib_service (struct rdma_cm_id *id , struct
rdma_ucm_ib_service *ibs );

like, that's the signature. copy it exactly, don't come for me about the spacing, that's just how she's written 💅

🎀 ARGUMENTS 🎀

  • id — okay so the docs literally say -- undescribed -- and i'm not gonna make something up, bestie. the manpage leaves her a mystery 🙈
  • ibs — same situation, -- undescribed --. iconic in a "we don't know her" way 💀
not me pointing out that both arguments are undescribed in the original. i'm just being faithful to the source, fr fr.

🔥 DESCRIPTION 🔥

so here's the tea. this function is optional in the rdma cm flow (yes, optional — she's not mandatory, she's a choice ✨).

you call it on the client side of a connection, and the timing matters, okay? it goes before you call rdma_resolve_route. the way that ordering is non-negotiable 😭

and the key detail: the resolution can be done once per rdma_cm_id. once. per id. don't be out here doing it multiple times, that's not the move 🫶

🌈 SEE ALSO 🌈

Kernel file ./include/rdma/rdma_cm.h — go look at her, she's right there 👑

and the whole friend group, in order:

literally the whole squad, all present and accounted for 💖

bestie sign-off time 🧚 this little beauty comes to you from ./include/rdma, dated October 2026 — mark your calendars, she's a fall release and she knows it 🍓💜

k bye, go resolve some service records responsibly ✨👑
