💖 probe::kprocess.exec — Kernel Process Tapset 💖

okay bestie, gather round, because this one is a bop ✨

---

🦋 NAME 🦋

probe::kprocess.exec — the moment a process tries to exec into a whole new program 👑

---

🌸 SYNOPSIS 🌸

probe kprocess.exec {}

that's it. that's the whole vibe. no args, no drama, just a probe hanging out waiting for something iconic to happen 💅

---

🎀 VALUES 🎀

these are the lil goodies you get to peek at when the probe fires. so many gifts 🫶

• argstr — a string with the filename first, then the arguments to pass, but excluding the 0th arg. (SystemTap v2.5+)
• name — the name of the system call, which is “execve”. yes, with the curly quotes, she's fancy like that. (SystemTap v2.5+)
• args — the arguments headed to the new executable, and this one does include the 0th arg. (SystemTap v2.5+)
• filename — the path to the new executable, aka where this whole glow-up is happening 📁

---

💜 CONTEXT 💜

who's the main character here? it's the caller of exec. them. they did that. 👏

---

✨ DESCRIPTION ✨

so basically this probe fires whenever a process attempts to exec to a new program. like, the second somebody tries to swap out their whole entire program, boom, this probe shows up to witness it. no cap. 🔥

and here's the tea: in SystemTap v2.5+, it's aliased to the syscall.execve probe. so they're the same thing, just different names. bestie behavior fr fr. 💀
