STRUCT BATADV_NEIGH_IFINFO(9)

💖 struct batadv_neigh_ifinfo(9) — Kernel API Manual 💖

okay bestie, welcome to the Kernel API Manual side of the group chat ✨ this one is all about struct batadv_neigh_ifinfo, and it's giving “neighbor info, but make it per outgoing interface” 💅

🌸 NAME 🌸

struct batadv_neigh_ifinfo — neighbor information per outgoing interface. That's the whole vibe: it's the little info holder for a neighbor, tracked per outgoing interface 🎀

✨ SYNOPSIS ✨

       struct batadv_neigh_ifinfo {
           struct hlist_node list;
           struct batadv_hard_iface *if_outgoing;
           struct batadv_neigh_ifinfo_bat_iv bat_iv;
         #ifdef CONFIG_BATMAN_ADV_BATMAN_V;
           struct batadv_neigh_ifinfo_bat_v bat_v;
         #endif;
           u8 last_ttl;
           struct kref refcount;
           struct rcu_head rcu;
        };

🎀 Members 🎀

• list — list node for batadv_neigh_node.ifinfo_list — yes, it's on the list, literally 🫶
• if_outgoing — pointer to outgoing hard-interface — the “where is this going” pointer 💫
• bat_iv — B.A.T.M.A.N. IV private structure — the B.A.T.M.A.N. IV private-structure slot 🌈
• bat_v — B.A.T.M.A.N. V private data — the B.A.T.M.A.N. V private-data slot ⭐
• last_ttl — last received ttl from this neigh node — exactly what it says, no cap 💀
• refcount — number of contexts the object is used — the usage counter keeping track of contexts 👑
• rcu — struct used for freeing in a RCU-safe manner — the RCU-safe free helper, iconic 🧚
