ENUM SGX_RETURN_CODE(9)

✨ NAME ✨

okay bestie, welcome to the enum sgx_return_code(9) page from the Kernel API Manual 💖. This is literally enum sgx_return_code — the return code type for ENCLS, ENCLU and ENCLV. no cap, that’s the whole name vibe.

🌸 SYNOPSIS 🌸

enum sgx_return_code {
    SGX_EPC_PAGE_CONFLICT ,
    SGX_NOT_TRACKED ,
    SGX_CHILD_PRESENT ,
    SGX_INVALID_EINITTOKEN ,
    SGX_PAGE_NOT_MODIFIABLE ,
    SGX_INSUFFICIENT_ENTROPY ,
    SGX_NO_UPDATE ,
    SGX_UNMASKED_EVENT

};

🎀 Constants 🎀

vibe check: these are the constants, and every single one matters 🫶

• SGX_EPC_PAGE_CONFLICT — page is being written by other ENCLS function. 💅
• SGX_NOT_TRACKED — previous ETRACK's shootdown sequence has not been completed yet. 😭
• SGX_CHILD_PRESENT — SECS has child pages present in the EPC. 🦋
• SGX_INVALID_EINITTOKEN — EINITTOKEN is invalid and enclave signer's public key does not match IA32_SGXLEPUBKEYHASH. 🚨
• SGX_PAGE_NOT_MODIFIABLE — the EPC page cannot be modified because it is in the PENDING or MODIFIED state. 🔒
• SGX_INSUFFICIENT_ENTROPY — insufficient entropy in RNG. 🎲
• SGX_NO_UPDATE — EUPDATESVN could not update the CPUSVN because the current SVN was not newer than CPUSVN. This is the most common error code returned by EUPDATESVN. 👑
• SGX_UNMASKED_EVENT — an unmasked event, e.g. INTR, was received. 📣
