💅 batadv_dat_c..._dump_bucket(9) — the Kernel API Manual, bestie edition 🎀

okay so real quick, this is a page from the Kernel API Manual and it's all about batadv_dat_cache_dump_bucket — say that five times fast, i dare u 😭

✨ NAME ✨

batadv_dat_cache_dump_bucket — dumps exactly one bucket of the DAT cache table out to a netlink socket. one bucket. not the whole table. she's doing her one (1) job and she's slaying it 💅

🌸 SYNOPSIS 🌸

int batadv_dat_cache_dump_bucket (struct sk_buff *msg , u32 portid ,
struct netlink_callback *cb , struct batadv_hashtable *hash , unsigned
int bucket , int *idx_skip );

like yes she returns an int, and yes there are six whole arguments, we'll get to every single one, don't stress 🫶

💖 ARGUMENTS 💖

  • msg — the buffer for the message, aka where the output goes. it's giving "hold my data" energy 🎀
  • portid — the netlink port. that's the address she's sending to, no cap ✨
  • cb — the Control block containing additional options. the little side-car of extra settings, iconic 💫
  • hash — the hash to dump. this is the table we're picking a bucket out of 🦋
  • bucket — the bucket index to dump. literally which bucket. that one. right there 👑
  • idx_skip — how many entries to skip. yes bestie, we're skipping, sometimes u gotta skip 😌

⭐ RETURN ⭐

0 or error code. that's it, that's the whole vibe — zero means we ate, anything else means something went sideways 💀

🌈 SEE ALSO 🌈

the kernel file lives at ./net/batman-adv/distributed-arp-table.c, and after that it's basically the entire batman-adv extended family reunion — every single one of these, no skipping (unlike idx_skip, we do NOT skip here 😤):

and that's the whole page bestie, go dump a bucket 🪣✨

💌 cute sign-off time: this lil page came from ./net/batman-adv, dated October 2026, and she answers to the name batadv_dat_c..._dump_bucket(9). mwah 💋🦋
