STRUCT BATADV_TVLV_HANDLER(9)

🦋 struct batadv_tvlv_handler(9) — the Kernel API Manual, bestie edition 🦋

Okay so picture this: it's struct batadv_tvlv_handler(9), right, and it is literally the handler for a specific tvlv type and version. That's the NAME energy. Main character vibes only. 💅

✨ SYNOPSIS ✨

struct batadv_tvlv_handler {
    struct hlist_node list;
    void (*ogm_handler)(struct batadv_priv *bat_priv, struct
batadv_orig_node *orig, u8 flags, void *tvlv_value, u16 tvlv_value_len);
    int (*unicast_handler)(struct batadv_priv *bat_priv, u8 *src, u8
*dst, void *tvlv_value, u16 tvlv_value_len);
    int (*mcast_handler)(struct batadv_priv *bat_priv, struct sk_buff
*skb);
    u8 type;
    u8 version;
    u8 flags;
    struct kref refcount;
    struct rcu_head rcu;
 };

Like, look at her. She's got a list node, three whole callback function pointers, some little u8 fields, a kref, and an rcu_head. She contains multitudes. 🫶

🎀 Members 🎀

• list — the hlist node for batadv_priv_tvlv.handler_list. She's gotta be in the group chat somehow. 💖
• ogm_handler — the handler callback that gets handed the tvlv payload to process on incoming OGM packets.
• unicast_handler — the handler callback that gets handed the tvlv payload to process on incoming unicast tvlv packets.
• mcast_handler — the handler callback that gets handed the tvlv payload to process on incoming mcast packet.
• type — the tvlv type this handler feels responsible for. Yes, feels. She's very invested. 🧚
• version — the tvlv version this handler feels responsible for. Same energy, different field. ✨
• flags — tvlv handler flags.
• refcount — the number of contexts the object is used. Basically her follower count but for contexts, ngl. 💀
• rcu — the struct used for freeing in an RCU-safe manner. She cleans up responsibly, we love that for her. 🌸

No cap, that is a lot of friends and every single one of them matters. 🔥🌈

Lowkey a whole little ecosystem in here and she's just one struct in it, but like... she's the one holding the callbacks. Respect the hustle. 😭💜

Okay byeeeee, this page came straight from ./net/batman-adv and it's dated October 2026 — so mark your calendars, bestie, because struct batadv_tvlv_handler(9) said see you then 💖✨🎀 slay, periodt. 🦋
