STRUCT SGX_ENCLAVE_ADD_PAGES(9)

🌸 struct sgx_enclave_add_pages(9) 🌸

hey bestie, welcome to the Kernel API Manual 💖 this one is short, sweet, and extremely specific: it’s all about the parameter structure for the %SGX_IOC_ENCLAVE_ADD_PAGE ioctl. iconic behavior, honestly.

✨ NAME ✨

struct sgx_enclave_add_pages — literally the parameter structure for the %SGX_IOC_ENCLAVE_ADD_PAGE ioctl. that’s the whole name, no cap 🫶

🦋 SYNOPSIS 🦋

struct sgx_enclave_add_pages {
    __u64 src;
    __u64 offset;
    __u64 length;
    __u64 secinfo;
    __u64 flags;
    __u64 count;
};

every single field is a __u64, bestie. we love a consistent little struct 💅

🎀 Members 🎀

• src — the start address for the page data. like, where the data begins, periodt.
• offset — the starting page offset. the offset at the start, iykyk.
• length — the length of the data, and it is a multiple of the page size. yes, that detail matters 🌈
• secinfo — the address for the SECINFO data. not the data itself, the address, okay? 💖
• flags — the page control flags. very flags, very control.
• count — the number of bytes added, also a multiple of the page size. matching page-size multiples, we love to see it ✨
