nvme_init_auth_receive(9)

💖 nvme_init_auth_receive — like, the manual page ✨

okay so bestie, welcome to nvme_init_auth_receive(9) from the libnvme API manual — this is the little void function that gets your passthru command all set up for Authentication Receive. no cap, it's a builder, it doesn't do the receiving itself, it just lays out the vibes so the command buffer is ready. 🎀

---

🌸 SYNOPSIS 🌸

void nvme_init_auth_receive (struct libnvme_passthru_cmd *cmd , __u16
spsp , __u8 secp , __u32 al , void *data , __u32 len );

she takes six arguments and returns void, so don't go looking for a return value, she's not that kind of girl 💅

---

🦋 ARGUMENTS 🦋

• cmd — the passthru command you're gonna use. this is the thing getting initialized, bestie, she's the main character ✨
• spsp — the Security Protocol Specific field (__u16). yes it's a field, yes you give it a value, we move 🫶
• secp — the Security Protocol (__u8). literally the protocol, that's it, that's the whole vibe 💜
• al — the protocol specific allocation length (__u32). allocation length. protocol specific. iconic ⭐
• data — the authentication message payload buffer you want the received data to land in 🍓
• len — data length of the payload in bytes. and it must match al — like, they have to be the same, no exceptions, don't play with her 😭

---

👑 DESCRIPTION 👑

so what she actually does: she initializes the passthru command buffer for the Fabrics Authentication Receive command 💖

and what's that for? it's how you receive a KX-HMAC-CHAP authentication message — for example a struct nvmf_auth_kxchap_challenge — from a controller. cute, right? 🔥

important note though: this is an NVMe-over-Fabrics specific command, okay? like, fabrics only, iykyk. and the way it works is it reuses the SECP/SPSP0/SPSP1/AL field encoding of the Security Receive command. so the field layout is giving Security Receive energy, but the command itself is Fabrics Authentication Receive. slay 💅✨

---

quick vibe check bestie: len must match al. that's the one thing the manpage yells about, so i'm yelling about it too 🫶

---

and that's the whole page, honestly. 🌈 she's short, she's sweet, she sets up your buffer and dips 💀

sign-off time: this little gem comes from the libnvme API manual, dated October 2026 — so go forth and initialize those auth receive commands, bestie, you've absolutely got this 💖🎀🦋🌸⭐👑
