tomoyo_supervisor(9)

📦 version 7.3.1, in nixpkgs unstable

Bestie, welcome to tomoyo_supervisor(9) from the Kernel API Manual — the page where we ask for the supervisor's decision, and it’s giving important little kernel moment energy 💅✨

🌸 NAME 🌸

tomoyo_supervisor — ask for the supervisor's decision. That’s the name, that’s the vibe, no cap 🫶.

✨ SYNOPSIS ✨

int tomoyo_supervisor (struct tomoyo_request_info *r , const char *fmt ,
... );

🎀 ARGUMENTS 🎀

  • r — pointer to struct tomoyo_request_info. Yes, that exact struct, periodt.
  • fmt — the printf's format string, followed by parameters.
  • ... — variable arguments.

💖 DESCRIPTION 💖

Okay so the return-value tea is wild but simple: it returns 0 if the supervisor decided to permit the access request which violated the policy in enforcing mode. It returns TOMOYO_RETRY_REQUEST if the supervisor decided to retry the access request which violated the policy in enforcing mode. It returns 0 if it is not in enforcing mode. Otherwise, it returns -EPERM.

That’s the whole decision menu — permit, retry, not enforcing, or -EPERM — and yes, the two 0 cases are both real, so read the conditions carefully bestie 😭.
