tomoyo_file_ioctl(9)

📦 version 7.3.1, in nixpkgs unstable

💅 tomoyo_file_ioctl — bestie's guide to the TOMOYO ioctl hook 💅

okay so real quick, this is a page from the Kernel API Manual (section 9, the kernel-functions girlies ✨), and it's literally about tomoyo_file_ioctl. that's the whole vibe. let's get into it 🎀

✨ NAME ✨

tomoyo_file_ioctl — the target for security_file_ioctl(). that's it, that's the job 💖

🌸 SYNOPSIS 🌸

int tomoyo_file_ioctl (struct file *file , unsigned int cmd , unsigned
       long arg );

like… it takes a file, a command, and an arg, and it returns an int. iconic signature tbh 👑

🦋 ARGUMENTS 🦋

  • file — a pointer to struct file. yes, the actual file object, no cap 🗂️
  • cmd — the command for the ioctl. this is what you're asking for, bestie 🎯
  • arg — the argument for cmd. it rides along with the command like a little sidekick 🫶

💀 DESCRIPTION 💀

Returns 0 on success, and a negative value otherwise. that's the whole description fr fr — no lore, no extra drama, just: zero means slay, negative means something went sideways 😭

🔥 SEE ALSO 🔥
