security_inet_csk_clone(9)

💅 security_inet_csk_clone — the Kernel API Manual glow-up 🎀

okay so bestie, welcome to the security_inet_csk_clone(9) page ✨ it lives in the Kernel API Manual, and it's honestly a tiny little function with main character energy. let's get into it 🫶

---

🌸 NAME 🌸

security_inet_csk_clone — no cap, this one sets the new sock's LSM state based on the request_sock 💖

---

✨ SYNOPSIS ✨

void security_inet_csk_clone (struct sock *newsk , const struct
request_sock *req );

literally returns void, so no return value drama. periodt 💅

---

🦋 ARGUMENTS 🦋

• newsk — the brand new sock, fresh out the box 🎁
• req — the connection's request_sock, i.e. where the vibe is coming from 👑

---

🔥 DESCRIPTION 🔥

so here's the tea ☕ — this function sets the LSM state of the sock using the LSM state from req. that's it. that's the whole function. short, sweet, iconic 🌈
