batadv_mcast_is_report_ipv4(9)

💖 NAME 💖

Okay so this is batadv_mcast_is_report_ipv4(9), straight out of the Kernel API Manual, bestie — and its whole job is: check for IGMP reports 💅✨

---

🎀 SYNOPSIS 🎀

bool batadv_mcast_is_report_ipv4 (struct sk_buff *skb );

---

🍓 ARGUMENTS 🍓

• skb — the ethernet frame destined for the mesh 🦋

---

🌸 DESCRIPTION 🌸

⚠️ Warning, bestie, this one is important: This function may reallocate the skb data buffer via ip_mc_check_igmp/.... 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. No cap, reacquire it after the call 💀

Checks whether the given frame is a valid IGMP report. That’s the whole vibe check 👑

---

⭐ RETURN ⭐

If so then true, otherwise false. Simple as that, periodt 💜
