💖 batadv_route_unicast_packet(9) 💖

okay so bestie, welcome to the Kernel API Manual glow-up for batadv_route_unicast_packet(9) — we’re gonna make this route-unicast situation make sense, no cap 💅

🎀 NAME 🎀

batadv_route_unicast_packet — forward a unicast packet towards its destination originator

✨ SYNOPSIS ✨

int batadv_route_unicast_packet (struct sk_buff *skb , struct batadv_hard_iface *recv_if );

🫶 ARGUMENTS 🫶

• skb — the received unicast packet, aka the packet that just showed up
• recv_if — interface on which the packet was received

🌸 DESCRIPTION 🌸

okay so here’s the tea: this function decrements the TTL, looks up the originator for the destination address, and hands the packet over to batadv_send_skb_to_orig for transmission. that’s the whole main-character sequence ✨

and if the TTL is exhausted or no route exists? boom, the packet gets dropped. not me being dramatic, that’s literally the rule 💀

🌈 RETURN 🌈

NET_RX_SUCCESS if the packet was forwarded, and NET_RX_DROP otherwise. return-value vibe check complete, periodt 💅
