batadv_netlink_vlan_fill(9)

📦 version 7.3.1, in nixpkgs unstable

okay so we're deep in the kernel API manual rn — this is batadv_netlink_vlan_fill from the Kernel API Manual, and yes she's a function, yes she's iconic, and yes she's about to fill a netlink message with vlan attributes. bestie, let's get into it 🎀

✨ SYNOPSIS ✨

int batadv_netlink_vlan_fill (struct sk_buff *msg , struct batadv_priv
*bat_priv , struct batadv_meshif_vlan *vlan , enum batadv_nl_commands
cmd , u32 portid , u32 seq , int flags );

like, that's the whole vibe check right there 👑

🌸 ARGUMENTS 🌸

okay so every single parameter, no skips, no cap:

  • msg — the netlink message you're dumping into. that's her home. that's where the content goes 💌
  • bat_priv — the bat priv holding, literally, all the mesh interface information. she knows everything about everybody, main character energy fr.
  • vlan — the vlan which was modified. this is the one we're talking about rn 🦋
  • cmd — the type of message to generate (it's an enum batadv_nl_commands, so like, pick your fighter ✨)
  • portid — the Port making the netlink request. say hi, she asked for this 💅
  • seq — the sequence number for the message. gotta keep them in order, order matters, it's giving organized 🎀
  • flags — Additional flags for message. sprinkle whatever extra you need on top 🌈

🔥 RETURN 🔥

0 on success — slay, we love a clean return 🫶

…or a negative error number in case of failure 😭 (and yes, negative means something went wrong, not me being dramatic for once)

ngl if you got here from a link and you're confused: you're in kernel space now, go read ./net/batman-adv/netlink.c and it'll all make sense (or it won't, but that's a tomorrow problem 🙈)

and that's the page, bestie! 💖 this whole thing lives in ./net/batman-adv, October 2026 edition, under the name batadv_netlink_vlan_fill(9) — mwah, go forth and fill those vlan attributes ✨🧚⭐
