batadv_bla_answer_request(9)

💅 batadv_bla_answer_request — from the Kernel API Manual, bestie 🎀

Okay so picture this: you're deep in the Kernel API Manual (yes, that's the manual name, we're fancy here), and you stumble onto page batadv_bla_answer_request. And it's literally the "hey bestie, here are MY claims again, please re-check" function. Iconic behaviour, honestly.

---

✨ NAME ✨

batadv_bla_answer_request — answer a bla request by sending own claims 🫶

---

🌸 SYNOPSIS 🌸

void batadv_bla_answer_request (struct batadv_priv *bat_priv , struct
batadv_hard_iface *primary_if , unsigned short vid );

It returns void, so like… no receipts, no return value, it just does the thing. Main character energy fr fr 💅

---

🦋 ARGUMENTS 🦋

• bat_priv — the bat priv with all the mesh interface information ✨ this is the whole vibe holder, all the mesh interface info lives in here.
• primary_if — interface where the request came on 📥 like, the door the knock came through.
• vid — the vid where the request came on 🏷️ the vid in question, matching the request's vid, no cap.

---

💖 DESCRIPTION 💖

So what does it actually do? It repeats all of our own claims, and then, finally, it sends an ANNOUNCE frame — which lets the requester do another check, to see if the CRC is correct now. 🔥

That's the whole arc. Re-claim everything, then announce, then let them re-verify. Chef's kiss, no notes. 🎀
