STRUCT UBIFS_SIG_NODE(9)

✨ struct ubifs_sig_node(9) ✨

okay bestie, so this is from the Kernel API Manual (yes, the kernel, we're fancy now 💅) and it's literally the glow-up node that lets other nodes get signed. Like, main character energy for authenticity. Let's get into it 🎀

---

🌸 NAME 🌸

struct ubifs_sig_node — the node for signing other nodes. no cap, that's its whole job 🫶

---

🦋 SYNOPSIS 🦋

struct ubifs_sig_node {
    struct ubifs_ch ch;
    __le32 type;
    __le32 len;
    __u8 padding[32];
    __u8 sig[];
};

look at that struct. iconic. not a single wasted field ✨

💖 Members 💖

• ch — the common header. every node's little starter pack, and this one's no different 🌈
• type — the type of the signature. rn the only one supported is UBIFS_SIGNATURE_TYPE_PKCS7, so yeah that's the vibe 💅
• len — the length of the signature data. gotta know how much sig you're getting, fr fr 📏
• padding — reserved for future, zeroes. it's literally just sitting there holding space for the future, we love a forward-thinking queen 👑
• sig — the signature data itself. the moment we've all been waiting for 🔥

ok that's the whole page bestie — every field, every reference, nothing skipped, and honestly? ate. 🍓
