mptcp_token_get_sock(9)

💅 mptcp_token_get_sock — a Kernel API Manual moment

okay so bestie, buckle up, because we're diving into mptcp_token_get_sock(9) — yes that's the page title, and yes it lives in the Kernel API Manual, and yes it's about to eat 💅✨

---

🦋 SYNOPSIS 🦋

struct mptcp_sock * mptcp_token_get_sock (struct net *net , u32 token );

like... she takes two things and gives you back a struct mptcp_sock *. iconic behavior honestly.

---

🎀 ARGUMENTS 🎀

• net — the namespace you're restricting the search to. keep it contained, queen 👑
• token — the token of the mptcp connection you're trying to retrieve. this is the ✨key✨ to the whole thing.

---

🌸 DESCRIPTION 🌸

so this function? it returns the mptcp connection structure that matches the given token. that's the whole vibe. 🫶

and the important bit, ngl — a reference count on the mptcp socket returned is taken. so like, it's yours now, handle it responsibly 🙈

---

💀 RETURN 💀

returns NULL if no connection with the given token value exists. that's it. that's the whole return section. no connection = NULL, no cap 💀
