💖 vti6_tnl_bucket(9) 💖

okay so bestie, welcome to the Kernel API Manual ✨ — today's main character is vti6_tnl_bucket, and honestly? she's serving looks in the IPv6 tunnel department 🎀

🌸 NAME 🌸

vti6_tnl_bucket — get head of list matching given tunnel parameters

like, she goes and finds the head of the list that matches the tunnel params you hand her. that's the whole vibe 💅

✨ SYNOPSIS ✨

struct ip6_tnl __rcu ** vti6_tnl_bucket (struct vti6_net *ip6n , const
struct __ip6_tnl_parm *p );

yes, that return type is a double pointer to a struct ip6_tnl with __rcu on it — she's fancy like that 🔥 don't retype it, just copy it exactly, iykyk.

🦋 ARGUMENTS 🦋

  • ip6n — the private data for ip6_vti in the netns 🫶 (yes, per-namespace, she's not a global girlie)
  • p — parameters containing tunnel end-points 📍

💜 DESCRIPTION 💜

okay so the way that vti6_tnl_bucket works is: it returns the head of the list matching the struct in6_addr entries laddr and raddr in p. 🧚

literally that's it, that's the tea — local address + remote address, that combo is the vibe check, and she hands you back the bucket head 🌈

⭐ RETURN ⭐

head of IPv6 tunnel list 👑 (the head, bestie — not the whole list, don't come for her)
