💅 batadv_tvlv_...ners_process(9) — a Kernel API Manual moment

okay bestie, so this is a page from the Kernel API Manual, and yes the function name in the header really is chopped like batadv_tvlv_...ners_process(9) — that's not me being lazy, that's what the man page calls itself. iconic of it honestly. anyway, sit down, grab a strawberry 🍓, we're reading a kernel doc.

✨ NAME ✨

batadv_tvlv_containers_process — she parses the tvlv buffer you hand her and calls the appropriate handlers. that's it, that's the whole job, and she does it slayfully 💅

🦋 SYNOPSIS 🦋

int batadv_tvlv_containers_process (struct batadv_priv *bat_priv , u8
packet_type , struct batadv_orig_node *orig_node , struct sk_buff *skb ,
void *tvlv_value , u16 tvlv_value_len );

like, literally just look at her signature. she's taking six things and returning an int. no cap.

🎀 ARGUMENTS 🎀

  • bat_priv — the bat priv, aka the one holding all the mesh interface information. she's the main character of this struct, keep her close 🫶
  • packet_type — tells you which packet type this TVLV handler is being called for. iykyk, it's giving "which group chat is this message for" energy
  • orig_node — the orig node that's emitting the ogm packet. king behavior from the originator ngl 👑
  • skb — the skb that the TVLV handler is called for. yes, that skb. the socket buffer in question. 🌸
  • tvlv_value — the tvlv content itself. the actual goods. the payload, if you will ✨
  • tvlv_value_len — the length of that tvlv content. because bestie, you can't just have content, you gotta know how much content

🔥 RETURN 🔥

so what does she give you back?

NET_RX_SUCCESS when she's processing an OGM — simple, clean, slay.

or the combined return value of all the called handler callbacks. and that combined value is one of:

  • NET_RX_SUCCESS
  • NET_RX_DROP
  • or, for BATADV_MCAST packets specifically, a negative errno code
lowkey important: that negative errno code is a BATADV_MCAST-only situation, so don't go expecting it on your regular OGM. 🫶

🌈 SEE ALSO 🌈

okay this is the part where the man page just starts listing her entire friend group and honestly? obsessed. the kernel file this lives in is:

./net/batman-adv/tvlv.c

and here's every single one of her besties, no one left behind 💜:

and that's the whole page, bestie. hope you understood it fr fr — it's giving "I read a kernel doc and survived" 💀✨

mwah 💋 — this page lives in ./net/batman-adv and it's dated October 2026, filed under the header batadv_tvlv_...ners_process(9). bye bestie, go parse some tvlv containers 🧚💖
