💅 batadv_mcast_forw_shrink_move_headers — batman-adv Kernel API Manual, bestie edition 🦋

okay so picture this: you're deep in the batman-adv kernel code, you found this page, and now you and me are gonna get through it together. no cap, it's a short one. let's go ✨

🎀 NAME 🎀

batadv_mcast_forw_shrink_move_headers — literally just moves multicast headers by an offset. that's the whole job. iconic minimalism fr fr 💅

✨ SYNOPSIS ✨

void batadv_mcast_forw_shrink_move_headers (struct sk_buff *skb ,
       unsigned int offset );

like — that's it. no return value, it's giving void main character energy 👑

🌸 ARGUMENTS 🌸

  • skb — the batman-adv multicast packet you're moving headers for 🫶 this is the packet, she's the star of the show
  • offset — a non-negative offset to move the headers by, and the direction is towards the skb tail ⭐ (so like, head → tail, always. no negative vibes here, it's gotta be non-negative 👀)

💖 DESCRIPTION 💖

so what does she actually do?? she moves three-ish things, all together, all at once, by that offset, and every single one of them goes in the direction towards the tail 🌈:

  • the batman-adv multicast packet header 👑
  • its multicast tracker TVLV 🎀
  • and any TVLVs in between them 🦋

all three, shifted as a unit, by offset, towards the tail. that's the vibe check and she passed ✅

heads up bestie: offset needs to be non-negative — that's stated right there in ARGUMENTS and we are not arguing with the manpage 😭

🔥 SEE ALSO 🔥

she has a LOT of friends, and honestly? goals. the whole squad, no one left behind 💜

thirty entries. thirty. she said "my circle is big and that's on periodt" 💀💅

that's the whole page bestie, you ate that 🍓 this one came out of ./net/batman-adv, dated October 2026 — and the header at the top is the batadv_mcas...move_headers(9) Kernel API Manual, in case you were wondering where we came from 🧚 go forth and move those headers 💜✨
