batadv_v_elp_packet_recv(9)

💅 batadv_v_elp_packet_recv(9) — like, the ELP packet handler era

okay bestie, buckle up, because we're diving into the Kernel API Manual and this one is a whole mood. The main character of today's episode is batadv_v_elp_packet_recv — the main ELP packet handler. Yes, THE main one. Not a side quest. Main. Character. Energy. 👑

---

✨ NAME ✨

batadv_v_elp_packet_recv — the main ELP packet handler 🎀

---

🌸 SYNOPSIS 🌸

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

like… it returns an int, it takes two structs, it's giving "I know exactly what I'm doing" — periodt. 💅

---

🦋 ARGUMENTS 🦋

• skb — the received packet 🍓 (yes, the actual packet, the whole reason we're here, no cap)
• if_incoming — the interface this packet was received through 🌈 (the ~vibes~ channel it came in on, iykyk)

---

💀 RETURN 💀

okay so this is important, don't skip it 🙈

• NET_RX_SUCCESS — and it consumes the skb if the packet was properly processed ✅ (like, it ate the skb and left no crumbs, obsessed)
• NET_RX_DROP — in case of failure 💀 (she tried, bestie, but the vibe check failed)

ngl bestie, this is kernel-space stuff — read the return values carefully and don't go dropping skbs in ways the kernel didn't ask for 🙏
