💅 batadv_transtable_search(9) — Kernel API Manual, but make it make sense

okay bestie, sit down, we're learning kernel API today. this one lives in the Kernel API Manual and it's literally the glow-up your mesh network needs. it's called batadv_transtable_search, and honestly? it's giving matchmaker energy. 🔥

✨ NAME ✨

batadv_transtable_search — get the mesh destination for a given client 🎯

🦋 SYNOPSIS 🦋

struct batadv_orig_node * batadv_transtable_search (struct batadv_priv
*bat_priv , const u8 *src , const u8 *addr , unsigned short vid );

like yes, it returns a struct batadv_orig_node * — a whole pointer, not a little guy. 💅

🌸 ARGUMENTS 🌸

four args, all of them main-character in their own way:

  • bat_priv — the bat priv with all the mesh interface information. it's the one holding the group chat, i.e. all the deets about your mesh interface 🫶
  • src — mac address of the source client. who's doing the talking 💬
  • addr — mac address of the destination client. who's getting talked to 📬
  • vid — VLAN identifier. gotta know which vlan lane we're in, no cap 🛣️

⭐ RETURN ⭐

it hands you a pointer to the originator that was selected as destination in the mesh for contacting the client addr, and NULL otherwise. periodt. 🫡

and like, the slay detail: if there are multiple originators serving the same client, the function returns the best one — best in terms of metric towards the destination node 👑🔥. we love a function that picks the icon of the group.

💀 DESCRIPTION 💀

one thing, and it's important, so listen up:

if the two clients are AP isolated, the function returns NULL. that's it, that's the vibe check, and they fail it 🙈

🧚 SEE ALSO 🧚

it's a whole friend group, fr fr. all of these live in the kernel file ./net/batman-adv/translation-table.c — here's everyone invited to the party 💖:

like… that's a lot of reading but they're all lowkey iconic in their own right, iykyk 📚✨
