💅 batadv_send_skb_via_tt_generic — kernel API manual, bestie edition 🦋

okay so you're in the Kernel API Manual and the page is literally called batadv_send_...a_tt_generic(9) — yes the title got truncated, no that's not a you problem, it's just how it's printed. anyway. sit down, hydrate, let's talk about sending an skb via TT lookup 💖

✨ NAME ✨

batadv_send_skb_via_tt_generic — send an skb via TT lookup. that's it. that's the whole vibe. 🎀

🌸 SYNOPSIS 🌸

int batadv_send_skb_via_tt_generic (struct batadv_priv *bat_priv ,
struct sk_buff *skb , int packet_type , int packet_subtype , u8
*dst_hint , unsigned short vid );

like, six args. she's high maintenance but she delivers. ✨

🫶 ARGUMENTS 🫶

  • bat_priv — the bat priv with all the mesh interface information. it's giving "walking folder of everything you need to know" energy. 👑
  • skb — payload to send. the actual little package. the main character of the packet world fr fr. 📦
  • packet_type — the batman unicast packet type to use. you pick which flavor. 🌈
  • packet_subtype — the unicast 4addr packet subtype (only relevant for unicast 4addr packets). so like… if you're not doing 4addr, this is lowkey just vibing there, unused. 🙈
  • dst_hint — can be used to override the destination contained in the skb. a little "actually, send it here" moment. 💅
  • vid — the vid to be used to search the translation table. this is your search key bestie, don't lose it. 🔑

💜 DESCRIPTION 💜

okay so here's the whole plot 🍓

It looks up the recipient node for the destination address in the ethernet header — via the translation table, obviously, that's literally in the name — and then it wraps the given skb into a batman-adv unicast or unicast-4addr header, depending on whether BATADV_UNICAST or BATADV_UNICAST_4ADDR was supplied as packet_type. then it sends this frame to the according destination node. slay. that's the whole thing. it ate and left no crumbs. 🔥

⭐ RETURN ⭐

NET_XMIT_DROP in case of error, or NET_XMIT_SUCCESS otherwise. two outcomes, no in-between, no "it's complicated" 😭
