💅 batadv_mcast_forw_shrink_tracker 💅

okay so first things first, bestie: this tiny icon is from the Kernel API Manual (yes, kernel docs can be cute too, it's giving ✨documentation glow-up✨). Full name is batadv_mcast_forw_shrink_tracker — the header just trims it down to batadv_mcast...rink_tracker(9) because screens are small and life is short 🎀

✨ NAME ✨

batadv_mcast_forw_shrink_tracker — literally just removes the zero addresses out of a tracker tvlv 🧹💖

🌸 SYNOPSIS 🌸

void batadv_mcast_forw_shrink_tracker (struct sk_buff *skb );

that's it. one argument. no cap. 🫶

🦋 ARGUMENTS 🦋

  • skb — the batman-adv multicast packet that we're gonna (potentially) shrink. yes, potentially, it's a vibe-check-first situation, not a guarantee 💅

🔥 DESCRIPTION 🔥

here's the tea ☕: this function goes through the given batman-adv multicast packet's tracker TVLV and removes all the destinations packing a zero MAC address (00:00:00:00:00:00). ghost addresses? gone. not on my watch 🙈

and because we are nothing if not responsible, it also updates the headers accordingly so the packet stays a valid batman-adv multicast packet. like, we're shrinking it but we're not out here breaking protocol. main character energy with a backup plan 💀✨

fr fr, the whole point is: strip the zeros, fix the headers, keep the packet valid. that's the entire assignment 👑
