🦋 batadv_mcast_want_rtr6_update(9) — a Kernel API Manual moment 💅

okay so bestie, welcome to the batadv_mcast_want_rtr6_update(9) page — yes that's the real full name, the header up top just gets truncated to batadv_mcas..._rtr6_update(9) because even man pages run out of room to flex. This is a Kernel API Manual entry and it's lowkey iconic. Let's get into it ✨

🌸 NAME 🌸

batadv_mcast_want_rtr6_update — update the want-all-rtr6 counter and the list, together, as a unit 🫶

⭐ SYNOPSIS ⭐

void batadv_mcast_want_rtr6_update (struct batadv_priv *bat_priv ,
struct batadv_orig_node *orig , u8 mcast_flags );

that's the whole signature, no cap. void return, three args, done. 💅

🎀 ARGUMENTS 🎀

  • bat_priv — the bat priv holding all the mesh interface information, like, all of it. main character energy for real 👑
  • orig — the orig_node whose multicast state might have changed. "might" is doing a lot of work here, go check it bestie 🙈
  • mcast_flags — the flags telling you the new multicast state. fresh out the oven, still warm 🍓

💖 DESCRIPTION 💖

Here's the tea: if the BATADV_MCAST_WANT_NO_RTR6 flag of this originator — that's orig — has toggled, then this method updates the counter and the list accordingly. both of them. together. slay. 🔥

⚠️ Caller needs to hold orig->mcast_handler_lock. like, this is not optional, this is not a suggestion — hold the lock or don't come to the function, periodt. 😭

🌈 SEE ALSO 🌈

all the siblings, cousins and distant relatives live in the kernel file ./net/batman-adv/multicast.c — here's the full family reunion, every single one, bestie, I would never skip a name 🧚:

that's the whole list, iykyk 🌸

and that's the page, bestie! 🫶 this gem lives in ./net/batman-adv and the version/date stamp on it says October 2026, with the footer doing its little batadv_mcas..._rtr6_update(9) encore because the truncation never sleeps. go hold that lock and update those counters, you've got this 💜✨🎀
