STRUCT SMEM_PRIVATE_ENTRY(9)

🎀 struct smem_private_entry(9) 🎀

okay bestie, so this is a page from the Kernel API Manual, and it's literally all about one little struct — struct smem_private_entry — which is the header of each item in the private partition. that's it, that's the whole vibe. it's the lil name tag every item in the private partition wears 💅

✨ SYNOPSIS ✨

here's the whole glow-up, exactly as it lives in the kernel:

struct smem_private_entry {
    u16 canary;
    __le16 item;
    __le32 size;
    __le16 padding_data;
    __le16 padding_hdr;
    __le32 reserved;
 };

🌸 MEMBERS 🌸

• canary — the magic number, and no cap, it must be SMEM_PRIVATE_CANARY. it's giving security guard energy, it checks your ID at the door 🫶
• item — the identifying number of the smem item. like a little student ID but for data 🎀
• size — size of the data, including padding bytes. don't forget the padding bestie, it counts 😭
• padding_data — number of bytes of padding of data 💖
• padding_hdr — number of bytes of padding between the header and the data. yes there's padding in the middle too, it's an aesthetic thing ✨
• reserved — for now reserved entry. it's just sitting there, main character energy, waiting for its moment 👑

fr fr, that canary field is not decorative — it must be SMEM_PRIVATE_CANARY, no exceptions, no "close enough" 💀
