STRUCT NFP_TUN_ACTIVE_TUNS_V6(9)

🌸 NAME 🌸

struct nfp_tun_active_tuns_v6 — the periodic lil' message that spills the tea on which IPv6 tunnels are actually active 💖 (this is the Kernel API Manual btw, so bestie brace yourself for kernel-level lore ✨)

✨ SYNOPSIS ✨

okay so here's exactly what this struct looks like, no cap, copy it character for character 🫶

struct nfp_tun_active_tuns_v6 {
    __be32 seq;
    __be32 count;
    __be32 flags;
    struct route_ip_info_v6 {
      struct in6_addr ipv6;
      __be32 egress_port;
      __be32 extra[2];
    } tun_info[];
};

💅 Members 💅

girl, let me introduce you to the whole cast of this struct, main character energy only 👑

• seq — the sequence number of the message. literally the vibes-checker that keeps things in order 🔥
• count — how many tunnels are being reported in this message. the headcount, the attendance sheet, the "how many of y'all showed up" 💀
• flags — the options part of the request. tiny little switches doing big things ✨
• tun_info — the tunnels that have actually sent traffic during the reported period. these are the ones that ate and left no crumbs 🍓
  • tun_info.ipv6 — the dest IPv6 address of the active route. where it's headed, iykyk 🌈
  • tun_info.egress_port — the port the encapsulated packet egressed from. the doorway it slipped out of 🚪✨
  • tun_info.extra — reserved for future use. it's giving "saving this seat for someone" 🙈
