generic_key_instantiate(9)

✨ NAME ✨

okay so bestie, this is the generic_key_instantiate(9) page from the Kernel API Manual — and it’s literally about simple instantiation of a key from preparsed data. that’s the whole name vibe 💅

🌸 SYNOPSIS 🌸

int generic_key_instantiate (struct key *key , struct
       key_preparsed_payload *prep );

🎀 ARGUMENTS 🎀

• key — the key that’s getting instantiated, obvi 🗝️
• prep — the preparsed data to load. yes ma’am, that’s the payload info 🫶

🦋 DESCRIPTION 🦋

So this function instantiates a key from preparsed data. The whole assumption here is that we can just copy the data in directly and clear the old pointers. no cap, that’s the move ✨

And yup — this can be pointed to directly by the key type instantiate op pointer. iconic little plug-in energy, honestly 🔌👑
