STRUCT MESH_TABLE(9)

💅 struct mesh_table(9)

okay so welcome to the Kernel API Manual bestie — today's main character is struct mesh_table, aka the mesh hash table, and honestly? she's holding the whole mesh together 🫶

---

✨ NAME ✨

struct mesh_table — mesh hash table. that's it, that's the vibe 🌸

---

🦋 SYNOPSIS 🦋

like, here's literally the whole struct, no cap:

struct mesh_table {
    struct hlist_head known_gates;
    spinlock_t gates_lock;
    struct rhashtable rhead;
    struct hlist_head walk_head;
    spinlock_t walk_lock;
    atomic_t entries;
 };

---

🎀 Members 🎀

okay so let's go member by member, iykyk 👑

• known_gates — the list of known mesh gates plus their mpaths, as seen by the station. and ngl, a gate's mpath may or may not be resolved and active — it's giving "it's complicated" 😭
• gates_lock — the lock that protects updates to known_gates. don't touch known_gates without her 💅
• rhead — the rhashtable containing struct mesh_paths, keyed by dest addr. iconic data structure behavior ✨
• walk_head — the linked list containing all mesh_path objects. she's just walking through, periodt 🚶‍♀️
• walk_lock — the lock protecting walk_head, obviously. no walk without her 🔒
• entries — the number of entries in the table. literally just counting, bestie 🔢
