smk_ptrace_mode(9)

okay so bestie, welcome to smk_ptrace_mode(9) from the Kernel API Manual — literally the helper function for converting PTRACE_MODE_* into MAY_*. It’s giving tiny translator with main character energy 💅

💅 NAME 💅

smk_ptrace_mode — the helper function for converting PTRACE_MODE_* into MAY_*. That’s the whole assignment, no cap.

---

✨ SYNOPSIS ✨

unsigned int smk_ptrace_mode (unsigned int mode );

---

🎀 ARGUMENTS 🎀

• mode — the input mode, in the form of PTRACE_MODE_*. That’s the vibe it expects, periodt.

---

🦋 DESCRIPTION 🦋

It returns a converted MAY_* mode that’s usable by smack rules. That’s the glow-up: PTRACE_MODE_* goes in, a MAY_* mode comes out, and smack rules can use it. Obsessed 💖
