STRUCT SERVICE_RANGE(9)

💖 NAME 💖

Okay so struct service_range(9) is from the Kernel API Manual, and it's literally the container for all bindings of a service range. That's the whole assignment, bestie. Vibe check: passed. 👑

✨ SYNOPSIS ✨

struct service_range {
    u32 lower;
    u32 upper;
    struct rb_node tree_node;
    u32 max;
    struct list_head local_publ;
    struct list_head all_publ;
 };

🫶 Members 🫶

• lower — service range lower bound. The bottom edge, fr fr. 🍓
• upper — service range upper bound. The top edge, no cap. 🌸
• tree_node — member of service range RB tree. It's the RB-tree link-up moment. 🌳
• max — the largest 'upper' in this node subtree. Keep an eye on that value, iykyk. 👀
• local_publ — list of identical publications made from this node; used by closest_first lookup and multicast lookup algorithm. That's the local-publication lineup. 💅
• all_publ — all publications identical to this one, whatever node and scope; used by round-robin lookup algorithm. The whole matching-publication friend group. 🫶
