__sock_create(9)

🌸 NAME 🌸

__sock_create — creates a socket. That’s the whole vibe, bestie: it creates a socket, no cap. 💖 This is the __sock_create(9) page from the Kernel API Manual, and it’s lowkey a main character in kernel socket land.

🦋 SYNOPSIS 🦋

int __sock_create (struct net *net , int family , int type , int
protocol , struct socket **res , int kern );

---

🎀 ARGUMENTS 🎀

• net — net namespace. The namespace bestie in question. 🌐
• family — protocol family (AF_INET, ...). This is the family energy. 👯
• type — communication type (SOCK_STREAM, ...). The communication style, iykyk. 💬
• protocol — protocol (0, ...). The protocol vibe. 📡
• res — new socket. This is where the shiny new socket gets assigned. ✨
• kern — boolean for kernel space sockets. Kernel-space or not, that’s the question. 👑

---

💅 DESCRIPTION 💅

So here’s the tea, bestie: this function creates a new socket and assigns it to res, passing through LSM. It returns 0 or an error. On failure, res is set to NULL — dramatic, but important. 😭

kern must be set to true if the socket resides in kernel space. And internally, this function uses GFP_KERNEL. That’s literally the allocation flex. 💅

bestie, do not forget: on failure res is set to NULL. That’s not a drill. 🫶
