📦 version 7.3.1, in nixpkgs unstable

💅 batadv_send_skb_packet(9) — send an already prepared packet ✨

okay so welcome to batadv_send_skb_packet(9) from the Kernel API Manual. This is the “packet is already packed, bestie, just send it” function. Let’s get into it 🫶

🎀 NAME 🎀

batadv_send_skb_packet — send an already prepared packet

✨ SYNOPSIS ✨

int batadv_send_skb_packet (struct sk_buff *skb , struct
batadv_hard_iface *hard_iface , const u8 *dst_addr );

💅 ARGUMENTS 💅

  • skb — the packet to send 💌
  • hard_iface — the interface to use to send the broadcast packet 📡
  • dst_addr — the payload destination 🎯

🦋 DESCRIPTION 🦋

Send out an already prepared packet to the given neighbor, or broadcast it using the specified interface. Either hard_iface or neigh_node must be not NULL. If neigh_node is NULL, then the packet is broadcasted using hard_iface; otherwise it is sent as unicast to the given neighbor. iykyk 💫

Big important thing: regardless of the return value, the skb is consumed. like, it’s gone, it’s not yours anymore, no take-backs 🫠

🌸 RETURN 🌸

A negative errno code is returned on a failure. A success does not guarantee the frame will be transmitted — it may be dropped due to congestion or traffic shaping. so yeah, success is giving “we tried” not “it arrived” 😭
