💖 NAME 💖

okay so bestie, welcome to the batadv_dat_..._arp_request(9) page from the Kernel API Manual ✨ this one is all about batadv_dat_snoop_incoming_arp_request — literally snooping the ARP request and trying to answer using the local DAT storage 🫶 no cap.

🦋 SYNOPSIS 🦋

bool batadv_dat_snoop_incoming_arp_request (struct batadv_priv *bat_priv
, struct sk_buff *skb , int hdr_size );

🎀 ARGUMENTS 🎀

• bat_priv — the bat priv with all the mesh interface information, bestie 🫶
• skb — packet to check 🔍
• hdr_size — size of the encapsulation header 📏

😭 DESCRIPTION 😭

⚠️ Warning: this function may reallocate the skb data buffer via batadv_dat_get_vid/... 💀 so any pointer into the skb data (e.g. obtained from skb->data or eth_hdr) before this call must be considered invalid afterwards and has to be reacquired. like, reacquire it, fr fr 🙈

🔥 RETURN 🔥

true if the request has been answered, false otherwise. slay ✅
