STRUCT BATADV_ALGO_IFACE_OPS(9)

🦋 struct batadv_algo_iface_ops — mesh algorithm callbacks (interface specific) 🦋

okay bestie, this is a struct from the Kernel API Manual, and it lives in <pink>kernel land</pink> so like… be respectful. It's struct batadv_algo_iface_ops, and it's literally the callback bag a mesh algorithm uses for the stuff that's specific to a single interface. Think of it as the interface-level half of the algo personality. 💅

✨ SYNOPSIS ✨

struct batadv_algo_iface_ops {
    void (*activate)(struct batadv_hard_iface *hard_iface);
    int (*enable)(struct batadv_hard_iface *hard_iface);
    void (*enabled)(struct batadv_hard_iface *hard_iface);
    void (*disable)(struct batadv_hard_iface *hard_iface);
    void (*update_mac)(struct batadv_hard_iface *hard_iface);
    void (*primary_set)(struct batadv_hard_iface *hard_iface);
};

not me retyping the whole struct for you 😭 — every function pointer is exactly as it appears, struct batadv_hard_iface *hard_iface and all. no cap.

🎀 MEMBERS 🎀

• activate — fires up the routing mechanisms when the hard-interface gets brought up. it's optional, so if you don't need it you can simply not.
• enable — init the routing info when the hard-interface is enabled. (note: returns int, unlike its void siblings ✨)
• enabled — a little notification that goes off when the hard-interface was enabled. also optional. it's giving "just letting you know bestie 🫶".
• disable — de-init the routing info when the hard-interface is disabled. the un-slay, if you will.
• update_mac — (re-)init the mac addresses of the protocol information belonging to this hard-interface. yes, the (re-) is doing real work there, keep it.
• primary_set — called when the primary interface is selected / changed. main character energy, literally 👑.

quick vibe check: activate and enabled are the only two marked (optional). the other four are just kind of… expected of you. no pressure though 💀
