ip6_tnl_bucket(9)

🌸 NAME 🌸

okay so bestie, this is ip6_tnl_bucket(9) from the Kernel API Manual — and it is literally here to get head of list matching given tunnel parameters. no cap, that's the whole assignment. 🎀

🦋 SYNOPSIS 🦋

struct ip6_tnl __rcu ** ip6_tnl_bucket (struct ip6_tnl_net *ip6n , const
struct __ip6_tnl_parm *p );

✨ ARGUMENTS ✨

• ip6n — the private data for ip6_vti in the netns. that's the netns private-data situation, bestie. 💅
• p — parameters containing tunnel end-points. yes, the endpoint-carrying params. 🫶

💖 DESCRIPTION 💖

ip6_tnl_bucket returns the head of the list matching the struct in6_addr entries laddr and raddr in p.

like, you hand it p, it looks at the struct in6_addr entries laddr and raddr in there, and you get back the head of the list that matches. it's giving “find me the right bucket for these tunnel endpoints” energy. 🌈

🔥 RETURN 🔥

head of IPv6 tunnel list. literally that. the return value is the head of the IPv6 tunnel list. periodt. 💅
