💖 vti6_locate(9) — Kernel API Manual 💖

okay bestie, welcome to the Kernel API Manual page for vti6_locate(9). it’s giving “find-or-make a tunnel” energy, and honestly? iconic. let’s get into it 🫶

🌸 NAME 🌸

vti6_locate — find or create a tunnel matching the parameters you give it. literally the whole point 💅

✨ SYNOPSIS ✨

struct ip6_tnl * vti6_locate (struct net *net , struct __ip6_tnl_parm *p
       , int create );

🎀 ARGUMENTS 🎀

• net — the network namespace. yes, the whole namespace vibe.
• p — tunnel parameters. this is the info it’s matching against.
• create — != 0 if you’re allowed to create a new tunnel when no match is found.

🦋 DESCRIPTION 🦋

So vti6_locate first tries to locate an existing tunnel based on parms. If that’s unsuccessful, but create is set, a new tunnel device is created and registered for use. that’s it, that’s the plot ✨

🔥 RETURN 🔥

The matching tunnel, or NULL. no cap.
