sgx_ioc_enclave_provision(9)

🌸 NAME 🌸

okay bestie, this is the sgx_ioc_enclave_provision(9) page from the Kernel API Manual, and it's literally the handler for %SGX_IOC_ENCLAVE_PROVISION. That's the whole vibe: a kernel handler doing its one iconic job. 💅

✨ SYNOPSIS ✨

long sgx_ioc_enclave_provision (struct sgx_encl *encl , void __user *arg
);

🎀 ARGUMENTS 🎀

• encl — an enclave pointer. That's it; it's a pointer to the enclave. 🫶
• arg — a userspace pointer to a struct sgx_enclave_provision instance. Yes, userspace pointer, so be normal about it. 🙈

💅 DESCRIPTION 💅

So what does it do? It allows ATTRIBUTE.PROVISION_KEY for an enclave by providing a file handle to /dev/sgx_provision. That's the entire described behavior — no extra lore, no invented side quests. 👑

🔥 RETURN 🔥

• 0: — Success. Slay. ✨
• -errno: — Otherwise. So if it's not 0, you're getting an error number vibe. 😭
