security_binder_transaction(9)

📦 version 7.3.1, in nixpkgs unstable

💖 NAME 💖

security_binder_transaction — check if a binder transaction is allowed. It's the security_binder_transaction(9) girlie from the Kernel API Manual, and she is here to vibe-check exactly one thing: whether a binder transaction can happen. Periodt.

✨ SYNOPSIS ✨

int security_binder_transaction (const struct cred *from , const struct cred *to );

🎀 ARGUMENTS 🎀

  • from — the sending process. She's the one sending it, bestie.
  • to — the receiving process. The one on the receiving end, no cap.

🦋 DESCRIPTION 🦋

Okay so the whole plot is literally this: check whether from is allowed to invoke a binder transaction call to to. That's the tea. That's the whole assignment. The security hook is just doing a little permission check before the binder transaction call goes through. Iconic behavior, honestly.

🌸 RETURN 🌸

Returns 0 if permission is granted. So 0 is the slay result here. 💅
