💅 libnvme(9) — bestie edition 🎀

okay so real talk, this page is from the libnvme API Manual and it's literally just about one little enum called enum nvmf_auth_rcodeex — the AUTH_Failure Reason Code Explanations (RCODEEX). it's giving "why did my authentication not slay" energy and honestly? iconic. let's get into it 💖

---

✨ NAME ✨

enum nvmf_auth_rcodeex — AUTH_Failure Reason Code Explanations (RCODEEX). yes bestie, it's a whole enum of why the auth failed, and every single reason is here. no cap. 🦋

---

🌸 SYNOPSIS 🌸

here's the whole thing, copy it exactly, don't @ me:

enum nvmf_auth_rcodeex {
    NVMF_AUTH_RCODEEX_FAILED ,
    NVMF_AUTH_RCODEEX_PROTOCOL_NOT_USABLE ,
    NVMF_AUTH_RCODEEX_SCC_MISMATCH ,
    NVMF_AUTH_RCODEEX_HASH_NOT_USABLE ,
    NVMF_AUTH_RCODEEX_KXGROUP_NOT_USABLE ,
    NVMF_AUTH_RCODEEX_INCORRECT_PAYLOAD ,
    NVMF_AUTH_RCODEEX_INCORRECT_MESSAGE

};

seven constants, all in a row, looking gorgeous. periodt. 👑

🧚 Constants 🧚

okay so let's do a vibe check on each one, one by one, because they all matter and i'm not skipping a single one 🙈

• NVMF_AUTH_RCODEEX_FAILED — Authentication failed: authentication of the involved host or NVM subsystem failed. yeah. it just. didn't work. the host or the NVM subsystem tried and flopped 😭
• NVMF_AUTH_RCODEEX_PROTOCOL_NOT_USABLE — Authentication protocol not usable: the protocol descriptors proposed by the host do not satisfy the security requirements of the controller. so the host showed up with protocol descriptors and the controller was like "bestie those do NOT meet my security requirements" 💅
• NVMF_AUTH_RCODEEX_SCC_MISMATCH — Secure channel concatenation mismatch: the SC_C value specified by the host does not satisfy the security requirements of the controller. the SC_C value the host specified? not it. controller said no. 🫶
• NVMF_AUTH_RCODEEX_HASH_NOT_USABLE — Hash function not usable: the HashIDList proposed by the host does not satisfy the security requirements of the controller. the HashIDList came through and the controller was lowkey unimpressed — doesn't satisfy the security requirements. hash function, rejected. 💀
• NVMF_AUTH_RCODEEX_KXGROUP_NOT_USABLE — Key exchange group not usable: the KXgIDList proposed by the host does not satisfy the security requirements of the controller. same situation, different list — the KXgIDList this time, and again it doesn't satisfy the controller's security requirements. key exchange group said goodbye 🔥
• NVMF_AUTH_RCODEEX_INCORRECT_PAYLOAD — Incorrect payload: the payload of the received message is not correct. the payload was just. wrong. incorrect. not correct. that's the whole thing 😭
• NVMF_AUTH_RCODEEX_INCORRECT_MESSAGE — Incorrect protocol message: the received message is not the expected next message in the authentication protocol sequence. the message arrived and it was NOT the next one we expected in the sequence. wrong place, wrong time, wrong message. main character energy but in a bad way 🙈

---

tiny reminder bestie: these are reason codes — they tell you why the auth attempt didn't go through, so next time the handshake can actually eat. 🍓

that's the whole page, fr fr. nothing skipped, nothing invented, all seven constants present and accounted for. now go forth and debug your authentication with confidence, my little enum enjoyer 🧚💜

— cute little sign-off: this was enum nvmf_auth_rcodeex from the libnvme(9) manual, dated October 2026. go slay your auth. ⭐🌈👑
