srpt_build_cmd_rsp(9)

💅 srpt_build_cmd_rsp — like, the kernel API manual, but make it make sense

okay so bestie, welcome to the srpt_build_cmd_rsp(9) page — this is a kernel API function, section 9, and it's the one that literally builds you an SRP_RSP response 🎀

---

✨ NAME ✨

srpt_build_cmd_rsp — build a SRP_RSP response. that's it, that's the whole job, and it does it flawlessly 💅

---

🌸 SYNOPSIS 🌸

int srpt_build_cmd_rsp (struct srpt_rdma_ch *ch , struct srpt_send_ioctx
*ioctx , u64 tag , int status );

it returns an int, it takes four things, and none of them are optional, so gather them all before you call, mwah 😌

---

🦋 ARGUMENTS 🦋

• ch — the RDMA channel that the request came in through. like, the exact doorway the request walked through, and yes you need it 💫
• ioctx — the I/O context tied to the SRP_CMD request. lowkey important: the response gets built in the buffer that ioctx->buf points at, which means this function will straight up overwrite your request data. not a drill, the request data is gone after this 🫶
• tag — the tag of the request you're generating this response for. match it up correctly or it's giving chaos 🎯
• status — the value that goes into the STATUS field of the SRP_RSP information unit. yes, exactly that field, capital letters and all 💅

---

👑 DESCRIPTION 👑

so what does it actually do? it returns the size in bytes of the SRP_RSP response it built. that's the return value, bestie — bytes, not vibes 📏

an SRP_RSP response carries a SCSI status or service response, and if you want the full format tea you gotta read section 6.9 in the SRP r16a document — that's where the whole layout of an SRP_RSP response lives 📖✨

also, for more info about sense data, go look at SPC-2. iconic reference, no cap 🌈
