STRUCT UBIFS_AUTH_NODE(9)

💖 struct ubifs_auth_node(9) 💖

okay so bestie, this is the Kernel API Manual entry for struct ubifs_auth_node — yes, the (9) is part of the title vibe, and we're keeping it. 🫶 It's a tiny struct page, but we're gonna treat it like the main character. 💅

🌸 NAME 🌸

struct ubifs_auth_node — node for authenticating other nodes. That's it, that's the whole job. No cap. ✨

✨ SYNOPSIS ✨

Here's the struct shape, verbatim, bestie — do not come for me about the braces:

struct ubifs_auth_node {
    struct ubifs_ch ch;
    __u8 hmac[];
};

Two fields, one [], very demure, very mindful. 🎀

🎀 Members 🎀

• ch — the common header. It's the shared header field, lowkey doing its little header thing. 🦋
• hmac — The HMAC. That's the HMAC field, periodt. 💅

🦋 SEE ALSO 🦋
