STRUCT BATADV_PRIV_GW(9)

💅 struct batadv_priv_gw(9) — per mesh interface gateway data

Okay bestie, welcome to the Kernel API Manual ✨ this one's all about struct batadv_priv_gw, aka the lil' bundle of gateway info that lives on every mesh interface. It's giving "backstage pass to the gateway selection drama" and honestly? Iconic. Let's get into it 🎀

✨ SYNOPSIS ✨

struct batadv_priv_gw {
    struct hlist_head gateway_list;
    spinlock_t list_lock;
    struct batadv_gw_node *curr_gw;
    unsigned int generation;
    enum batadv_gw_modes mode;
    u32 sel_class;
    u32 bandwidth_down;
    u32 bandwidth_up;
    atomic_t reselect;
 };

Yes queen, that's the whole struct, copy it exactly, no cap 🫶

🌸 Members 🌸

• gateway_list — the list of all the gateway nodes that are available out there. Basically the group chat roster of gateways 👑
• list_lock — the lock that protects gateway_list, curr_gw, and generation. Do not touch those without it, fr fr, that's the whole point 💀
• curr_gw — pointer to the gateway node that's currently selected. The main character of the moment ✨
• generation — the current (generation) sequence number. It's giving "which round of the selection are we on" 🌈
• mode — how the gateway operates: off, client, or server (peep batadv_gw_modes for the deets) 🦋
• sel_class — the gateway selection class, and yes it only applies if gw_mode is client 🎀
• bandwidth_down — the advertised uplink download bandwidth (only if gw_mode is server) 🍓
• bandwidth_up — the advertised uplink upload bandwidth (also only if gw_mode is server) 🍓
• reselect — a bool saying a gateway re-selection is currently in progress. Not me watching the whole thing reshuffle 😭
