💅 libnvme(9) — okay bestie, let's talk struct nvmf_auth_kxchap_success1

So this is an API Manual page from libnvme(9), and today's main character is a struct with the longest name ever: struct nvmf_auth_kxchap_success1. It's the KX-HMAC-CHAP_Success1 message, controller to host — like, the controller is sliding into the host's DMs to say "auth went great ✨". No cap, that's the whole vibe.

🌸 NAME 🌸

struct nvmf_auth_kxchap_success1 — the KX-HMAC-CHAP_Success1 message, controller to host. That's it, that's the name, she's iconic and she's long 🎀

---

✨ SYNOPSIS ✨

Here's the whole struct, copied exactly, because we do not edit the source in this house:

struct nvmf_auth_kxchap_success1 {
    __u8 auth_type;
    __u8 auth_id;
    __u16 rsvd2;
    __le16 t_id;
    __u8 hl;
    __u8 rsvd7;
    __u8 rvalid;
    __u8 rsvd9[7];
    __u8 rval[];
 };

Lowkey a lil' field trip through every member, so let's go 👑

🦋 Members 🦋

Okay so, field by field, no skipping, I promise 🫶

• auth_type — the Authentication Type, and for the full deets you gotta see enum nvmf_auth_protocol_id. She's the "which protocol are we even doing" girlie.
• auth_id — the Authentication Identifier, explained over in enum nvmf_auth_kxchap_id. Basically her ID badge 💳
• rsvd2 — Reserved. Don't touch, don't look at her too long, she's just vibing in the background 🙈
• t_id — the Transaction Identifier. Gotta know which transaction we're in, iykyk.
• hl — Hash Length: literally the length, in bytes, of the selected hash function. Numbers matter bestie, this is not vibes-only 😭
• rsvd7 — Reserved. Another reserved queen, leave her be 💀
• rvalid — Response Valid: it's 01h if rval carries a valid Response Value (that means bidirectional authentication was requested), and 00h otherwise. So like, a little boolean with big feelings ⭐
• rsvd9 — Reserved. Yep. Again. Reserved squad stays winning 🌈
• rval — the Response Value (R2, hl bytes), and it gets cleared to 0h if rvalid is 00h. Important!! No stale response values allowed, we clear that out 🧹

Real talk: rsvd2, rsvd7, and rsvd9 are Reserved — treat them as such. That's a technical caveat, not a suggestion, and I'm saying it clearly so nobody comes for me 💅
