💅 batadv_tp_send_ack(9) — aka the "send an ACK packet" page

Okay so bestie, buckle up 🌸 this is batadv_tp_send_ack(9), straight out of the Kernel API Manual — a whole function whose entire personality is sending an ACK packet. That's it. That's the job. It's giving "one small job, done slayfully." ✨

🎀 NAME 🎀

batadv_tp_send_ack — send an ACK packet 💌

✨ SYNOPSIS ✨

int batadv_tp_send_ack (struct batadv_priv *bat_priv , const u8 *dst ,
u32 seq , __be32 timestamp , const u8 *session , int socket_index );

Six arguments, no cap. Let's meet them 🫶

🦋 ARGUMENTS 🦋

  • bat_priv — the bat priv 🦇 with all the mesh interface information in it. Everything you need to know about the mesh lives here, lowkey the main character of the struct.
  • dst — the mac address 📍 of the destination originator. This is where the ACK is headed, periodt.
  • seq — the sequence number you're ACKing 🔢. Yeah, that one.
  • timestamp — the timestamp to echo back in the ACK ⏰. It literally just gets echoed, iconic behaviour honestly.
  • session — session identifier 🪪. Gotta know which session we're in, iykyk.
  • socket_index — local ICMP socket identifier 🔌. The local socket's lil name tag.

🌈 RETURN 🌈

  • 0 on success 🎉 — we ate, no crumbs.
  • a positive integer representing the reason of the failure otherwise 😭 — so if it's not zero, something went wrong and the number is spilling the tea about why.

Heads up bestie, this list is LONG. Like, "my group chat when someone says 'guess what'" long. Every single one of these, no skipping 💅

Fifty references, bestie. Fifty. Obsessed with the commitment honestly 💜

And that's the whole page, mwah 💋 This lil masterpiece lives over in ./net/batman-adv, dated October 2026 🌸 — go forth and ACK responsibly, you gorgeous nerd 🎀✨🦋
