TAPSET::CONTEXT(3stap)

💖 tapset::context — the systemtap context tapset 💖

okay bestie, pull up a chair because this one is literally the group chat of SystemTap tapsets 🫶 it's tapset::context from section 3stap, and it's the one you hit up when you need to know where your event happened and who it happened to.

---

✨ DESCRIPTION ✨

So here's the vibe: context functions are the ones that give you the extra little deets about where an event occurred. We're talking backtraces back to the scene of the crime, current register values for the processor, all of it. It's giving detective energy 🔍 and honestly? iconic.

Here's every single one of them, no skips, no cuts, all 45 of them 💅

• ns_gid — Returns the group ID of a target process as seen in a user namespace. See function::ns_gid(3stap) for the full deets.
• egid — Returns the effective gid of a target process. See function::egid(3stap) for the full deets.
• ns_egid — Returns the effective gid of a target process as seen in a user namespace. See function::ns_egid(3stap) for the full deets.
• uid — Returns the user ID of a target process. See function::uid(3stap) for the full deets.
• ns_uid — Returns the user ID of a target process as seen in a user namespace. See function::ns_uid(3stap) for the full deets.
• euid — Return the effective uid of a target process. See function::euid(3stap) for the full deets.
• ns_euid — Returns the effective user ID of a target process as seen in a user namespace. See function::ns_euid(3stap) for the full deets.
• is_myproc — Determines if the current probe point has occurred in the user's own process. See function::is_myproc(3stap) for the full deets.
• cpuid — Returns the current cpu number. See function::cpuid(3stap) for the full deets.
• cpu — Returns the current cpu number. See function::cpu(3stap) for the full deets.
• registers_valid — Determines validity of register() and u_register() in current context. See function::registers_valid(3stap) for the full deets.
• user_mode — Determines if probe point occurs in user-mode. See function::user_mode(3stap) for the full deets.
• is_return — Whether the current probe context is a return probe. See function::is_return(3stap) for the full deets.
• target — Return the process ID of the target process. See function::target(3stap) for the full deets.

okay that's the whole page bestie, you ate that 🍓 go probe something cute. this was the SystemTap Tapset Reference, dated September 2026, and yes the version is still TAPSET::CONTEXT(3stap) — we're consistent like that 💜 bye mwah 😘
