rdma_reject(9)

📦 version 7.3.1, in nixpkgs unstable

💅 rdma_reject — from the Kernel API Manual, bestie ✨

okay so picture this: you're deep in the kernel, somebody's trying to open a connection to you, and you are simply not interested. enter rdma_reject(9) — the "new phone who dis" of the RDMA connection manager 🎀

✨ NAME ✨

rdma_reject — the function you call to reject a connection request or response. that's it, that's the whole vibe. you're the bouncer, the velvet rope stays up, no cap 🫶

✨ SYNOPSIS ✨

int rdma_reject (struct rdma_cm_id *id , const void *private_data , u8
       private_data_len , u8 reason );

it returns an int, she takes four arguments, and yes she eats every single time 🔥

✨ ARGUMENTS ✨

okay so the docs here are lowkey iconic in the worst way, because the original literally says -- undescribed -- for every single one of these. so here's the honest tea ☕ — i'm not gonna invent lore that isn't there:

  • id — -- undescribed -- 🙈 the manpage gives us nothing on this one, bestie. it's a struct rdma_cm_id * and that's all we're getting.
  • private_data — -- undescribed -- 😭 a const void * with zero explanation attached. mysterious. main character energy, honestly.
  • private_data_len — -- undescribed -- 💀 a u8. that's the entire description. don't shoot the messenger.
  • reason — -- undescribed -- 🦋 also a u8, also completely unexplained. the lore is not forthcoming.
ngl i wish i had more for you on these, but the rule is keep every detail and add nothing, so here we are — -- undescribed -- four times in a row and i'm just as shook as you are 💜

this is where the page really pops off, because the whole friend group gets a shoutout 🌈 and heads up, it all lives in the Kernel file ./include/rdma/rdma_cm.h — that's the source file right there, iykyk 📁

like, twenty-one whole cross-references. she's connected, she knows everybody, she's literally the socialite of include/rdma 👑

and that's the page!! mwah 💋 it lives in ./include/rdma, it's dated October 2026, and the whole thing answers to rdma_reject(9) — go forth and reject those connections with your whole chest, bestie 🧚🌸⭐
