AUDIT_SETLOGINUID(3)

💖 AUDIT_SETLOGINUID 💖

okay bestie, so this is a page from the Linux Audit API and it's literally the manual for audit_setloginuid(3) — the lil function that tells the kernel who's actually logged in. yes, that's the whole vibe. let's go 🦋

---

✨ NAME ✨

audit_setloginuid — set a program's loginuid value

---

🌸 SYNOPSIS 🌸

#include <libaudit.h>

int audit_setloginuid(uid_tuid);"

ngl, yes, that trailing " is really in there. we do not touch the code blocks. we just vibe around them 💅

---

💫 DESCRIPTION 💫

So like. This function sets the task attribute loginuid to whatever uid you hand it.

Now here's the tea, and it's important tea: the loginuid value may only be set by programs that have the CAP_AUDIT_CONTROL capability. and what does that normally mean? it means the root account. that's it. that's the gatekeeper. 🔥

The loginuid value lives in the task structure and is inherited by child processes — so it follows your whole little process family tree around, no cap.

What's it even for? it's used to track what account a user gained system access with. it's the receipts of "which door did you come in through" 🚪✨

And the way that every single system entry point program should be doing this?? They should set this value right before changing to the uid of the user granted access, so that audit events are properly attributed to that user. that's the whole assignment bestie, it's giving correct attribution main character energy 👑

---

🎀 RETURN VALUE 🎀

This function returns 0 on success and non-zero otherwise. that's it. that's the whole return value. simple. iconic. periodt 💅
