batadv_v_ogm_packet_recv(9)

📦 version 7.3.1, in nixpkgs unstable

💖 batadv_v_ogm_packet_recv — the OGM2 receiving handler, bestie 💖

okay so quick vibe check: you're in the Kernel API Manual (yes, the whole manual, we're fancy now 👑) and this page is all about batadv_v_ogm_packet_recv(9), aka the OGM2 receiving handler. it's giving "the person who answers the door when a packet shows up" energy, and honestly? iconic. ✨

🌸 SYNOPSIS 🌸

int batadv_v_ogm_packet_recv (struct sk_buff *skb , struct
       batadv_hard_iface *if_incoming );

that's it. that's the whole function signature. short, sweet, and about to Handle Business 💅

🎀 ARGUMENTS 🎀

  • skb — the received OGM 🍓 like, the actual packet that just rolled up. this is the main character of the whole operation, ngl.
  • if_incoming — the interface where this OGM has been received 🦋 so we know which door it knocked on. very important for the plot.

⭐ RETURN ⭐

so here's how it goes down at the end:

  • NET_RX_SUCCESS and it consumes the skb on success 🎉 i.e. the skb gets eaten (respectfully) and everything slays.
  • NET_RX_DROP (and it frees the skb) on failure 💀 so like, the packet didn't make it, but at least it's freed and not just... floating around being a memory leak. we love a clean exit.
lowkey important: both paths deal with the skb — one consumes it, one frees it. no skb left behind, periodt 🫶
