set_security_override(9)

💅 set_security_override(9) — ok so this is from the Kernel API Manual bestie 🎀

Hiii so you clicked on a section 9 manpage, that's kernel API territory, and honestly? We love a low-level moment. This one is called set_security_override and it's literally about swapping out the security ID in a set of credentials. Iconic. Let's get into it. ✨

---

🌸 SYNOPSIS 🌸

int set_security_override (struct cred *new , u32 secid );

That's the whole vibe — it returns an int, and it takes two things. Slay.

---

🫶 ARGUMENTS 🫶

• new — the credentials you're gonna alter. That's your glow-up target bestie 💖
• secid — the LSM security ID you're setting. This is the new value, the main character 🎀

---

✨ DESCRIPTION ✨

So what does it actually do? set_security_override sets the LSM security ID inside a set of credentials, and the whole reason is so that the subjective security gets overridden when an alternative set of credentials is used. That's it, that's the teapot 🫖 — no cap, that's literally the described behaviour.

Lowkey important: this is about the security ID in credentials, and about the subjective security being overridden when an alternative set of credentials comes into play. Don't let anyone tell you otherwise 💅
