cipso_v4_sock_getattr(9)

💅 cipso_v4_sock_getattr(9) 💅

Okay so bestie, welcome to the cipso_v4_sock_getattr page from the Kernel API Manual — yes, the kernel, yes the fancy one, and yes you're gonna get it, iykyk 🫶

---

✨ NAME ✨

cipso_v4_sock_getattr — literally the function that gets the security attributes from a sock 🧦 no cap

---

🎀 SYNOPSIS 🎀

int cipso_v4_sock_getattr (struct sock *sk , struct netlbl_lsm_secattr
*secattr );

That's the whole vibe check right there. Two things go in, an int comes out 💫

---

🦋 ARGUMENTS 🦋

• sk — the sock 🌸 like, the actual socket you're interrogating. Be nice to it.
• secattr — the security attributes 💖 this is where the tea gets poured out.

---

👑 DESCRIPTION 👑

So here's the situation, bestie. This function queries sk to see if there's a CIPSO option attached to the sock — and if there is, it returns those CIPSO security attributes in secattr ✨ iconic behavior, honestly.

⚠️ Now, the important part, the part you cannot skip, the part that's giving "read the group chat before you reply": this function requires that sk be locked, or privately held, but it does not do any locking itself 💀 So like… that's on you. It's not gonna lock anything for you. It's not your mom. Do not come for this function when you didn't lock your own sock, fr fr.

It returns zero on success and negative values on failure 🌈 zero = slay, negative = 😭.
