STRUCT BATADV_ORIG_IFINFO(9)

💅 struct batadv_orig_ifinfo — originator info per outgoing interface

okay bestie, so this is a page from the Kernel API Manual, section 9 (kernel structs, the fun ones). It's literally just describing one struct, and the struct is giving "one originator, seen through one outgoing interface" — that's the whole vibe. Let's get into it 🫶

✨ SYNOPSIS ✨

Here's the whole shape of it, exactly as it lives in the kernel, no cap:

struct batadv_orig_ifinfo {
    struct hlist_node list;
    struct batadv_hard_iface *if_outgoing;
    struct batadv_neigh_node *router;
    u32 last_real_seqno;
    u8 last_ttl;
    u32 last_seqno_forwarded;
    unsigned long batman_seqno_reset;
    struct batadv_orig_ifinfo_bat_iv bat_iv;
    struct kref refcount;
    struct rcu_head rcu;
 };

🌸 Members 🌸

Like, every field, one by one, no skipping 💖

• list — the list node that hooks this thing into batadv_orig_node.ifinfo_list. It's how this struct finds its people 👯
• if_outgoing — pointer to the outgoing hard-interface. The specific interface this info is about 🦋
• router — the router that should be used to reach this originator. Your main character route ✨
• last_real_seqno — the last and best known sequence number. Both. It's an overachiever 🔥
• last_ttl — the ttl of the last received packet 🎀
• last_seqno_forwarded — the seqno of the OGM that was forwarded last. Very "I remember what I sent" of it 💅
• batman_seqno_reset — the time when the batman seqno window was reset ⏰
• bat_iv — the B.A.T.M.A.N. IV private structure. Its own little private club 🧚
• refcount — the number of contexts the object is used. Basically its group chat member count 😭
• rcu — the struct used for freeing in an RCU-safe manner. Cleanup, but make it safe 🌈

Heads up: this is a long one. The kernel file this page points at is ./net/batman-adv/types.h, and then it just keeps going, and going, and going. All of these, fr fr:
