💅 batadv_mcast_forw_push_want_rtr(9) — the Kernel API Manual moment

okay so bestie, welcome to the batadv_mcast_forw_push_want_rtr page from the Kernel API Manual 🌸 — yes the title is truncated with ... in the header, that's just how it's printed, don't come for me 😭.

✨ NAME ✨

🦋 SYNOPSIS 🦋

bool batadv_mcast_forw_push_want_rtr (struct batadv_priv *bat_priv ,
struct sk_buff *skb , unsigned short vid , unsigned short *num_dests ,
unsigned short *tvlv_len );

🎀 ARGUMENTS 🎀

  • bat_priv — the bat priv with all the mesh interface information 💖 like, it's holding all the receipts for the mesh interface
  • skb — the skb to push the destination addresses onto 📥 that's the packet getting the addresses yeeted onto it
  • vid — the vlan identifier 🏷️
  • num_dests — a pointer to store the number of pushed addresses in 🔢 it writes the count back out to you
  • tvlv_len — stores the amount of currently pushed TVLV bytes 📏

🔥 DESCRIPTION 🔥

Push the MAC addresses of all originators which have indicated interest in this multicast packet through the want-all-rtr flag onto the given skb. 💅

So basically: every originator that was like "yes bestie I want this multicast packet" via the want-all-rtr flag — their MAC addresses get pushed onto the skb. no cap. ✨

👑 RETURN 👑

true on success, false otherwise. 🫶 that's it, that's the whole vibe check.
