🌈 _batadv_tt_update_changes(9) 🌈

okay so bestie, this is a page straight out of the Kernel API Manual and it's all about one lil function that makes the mesh's translation table actually do the thing 💅 buckle up.

🌸 NAME 🌸

_batadv_tt_update_changes — apply a list of TT changes to the global TT ✨

(that's the whole vibe: you got a list of changes, you're applying them, no cap)

🦋 SYNOPSIS 🦋

void _batadv_tt_update_changes (struct batadv_priv *bat_priv , struct
batadv_orig_node *orig_node , struct batadv_tvlv_tt_change *tt_change ,
u16 tt_num_changes , u8 ttvn );

literally just five args, she's not complicated 🎀

💖 ARGUMENTS 💖

  • bat_priv — the bat priv, aka the whole mesh interface info situation, the main character's backpack 🎒
  • orig_node — the originator that's out here announcing the changes, iykyk
  • tt_change — an array of TT change entries you're about to apply, one by one
  • tt_num_changes — how many entries are in tt_change, aka the count, aka don't lose track bestie
  • ttvn — the TTVN of orig_node that corresponds to tt_change

👑 DESCRIPTION 👑

So the move here is: walk tt_change and add/remove the announced clients in the global TT. That's it, that's the function, and she ate 🔥

⚠️ but here's the important part: it aborts early and does not mark the orig_node TT as initialized if adding an entry fails — so that the next TT request can re-sync the full table. it's giving "graceful retreat", not "crash and burn" 💀

so like. if a single add doesn't go through? she's out, she's not flagging anything as initialized, and the next TT request gets to come through and re-sync the whole table. self-healing queen behavior honestly 🧚

🎀 SEE ALSO 🎀

okay this list is LONG and I'm obsessed, so here we go — all of it, in the kernel file ./net/batman-adv/translation-table.c 🌸

like I said. iconic list. go read them all, periodt 💜

and that's the whole page bestie 🫶 this cutie lives under ./net/batman-adv and it's stamped October 2026 — go forth and sync those tables ✨💅🌟
