💖 ipe_kernel_read_file(9) 💖

okay so bestie, welcome to the glow-up of the Kernel API Manual page for ipe_kernel_read_file(9) — yes that's the section 9 hook doc, iykyk. this one's a little baby page but it matters, so let's get into it 🫶

✨ NAME ✨

ipe_kernel_read_file — the ipe security hook function for kernel read. that's it, that's the whole vibe check. 💅

🌸 SYNOPSIS 🌸

int ipe_kernel_read_file (struct file *file , enum kernel_read_file_id
id , bool contents );

look at that signature. gorgeous. iconic. no notes. 👑

🎀 ARGUMENTS 🎀

  • file — supplies a pointer to the file structure that's being read in from disk. it's giving "here's the file, do ur thing" 🦋
  • id — supplies the enumeration identifying why the read is happening. the whole purpose. the main character energy of the read, fr fr.
  • contents — unused. literally just sitting there. not part of the plot. 💀

🦋 DESCRIPTION 🦋

so this LSM hook gets called when a file is read from disk in the kernel. that's the entire description, no cap — this hook is a straightforward little gremlin that shows up whenever the kernel does a disk read. 😭✨

🔥 RETURN 🔥

  • 0 — success!! we ate, we slayed, everything's fine 💖
  • -EACCES — did not pass IPE policy. blocked. denied. not today. 🙈
