batadv_send...nicast_4addr(9)

📦 version 7.3.1, in nixpkgs unstable

💖 NAME 💖

okay so bestie, welcome to batadv_send...nicast_4addr(9) — yes that's the manual name, it's giving "my name got cut off in a group chat preview" energy and honestly we love her anyway 🎀

The function in question is batadv_send_skb_prepare_unicast_4addr, and what she does is encapsulate an skb with a unicast 4addr header. That's it. That's the whole vibe. ✨

✨ SYNOPSIS ✨

bool batadv_send_skb_prepare_unicast_4addr (struct batadv_priv *bat_priv
, struct sk_buff *skb , struct batadv_orig_node *orig , int
packet_subtype );

like, copy it exactly, no cap, bool in front and everything 💅

🫶 ARGUMENTS 🫶

  • bat_priv — the bat priv with all the mesh interface information. she's the main character holding every detail about the mesh interface, so be nice to her 👑
  • skb — the skb containing the payload to encapsulate. it's the lil package getting wrapped up 🎁
  • orig — the destination node. where we're sending this whole situation 🦋
  • packet_subtype — the unicast 4addr packet subtype to use. pick your fav, it's literally the label on the box 🏷️

💅 RETURN 💅

So the tea is:

  • false if the payload could not be encapsulated 😭 (the wrap did not go well, tragic)
  • true otherwise 🎉 (encapsulation slayed, we move)

ngl it really is that simple, bestie 🫶
