batadv_tt_local_crc(9)

📦 version 7.3.1, in nixpkgs unstable

🌸 batadv_tt_local_crc(9) — the kernel API manual, bestie edition 🌸

okay so this is a page from the Kernel API Manual, and it's about batadv_tt_local_crc. Yes the name is a mouthful, iykyk, but it's literally just "compute the checksum of the local translation table" and honestly? iconic behavior. Let's get into it 💅

✨ NAME ✨

batadv_tt_local_crc — calculates the checksum of the local table 🎀

no cap, that's the whole vibe. it crunches the numbers on the local table and hands you a checksum back.

🦋 SYNOPSIS 🦋

u32 batadv_tt_local_crc (struct batadv_priv *bat_priv , unsigned short
vid );

look at that signature. it's giving "small function, big responsibility." you pass it two things, it gives you back a u32. periodt.

💖 ARGUMENTS 💖

  • bat_priv — the bat priv with all the mesh interface information. this is the main character, it's got every last detail about the mesh interface in there 🫶
  • vid — VLAN identifier for which the CRC32 has to be computed. so like, which VLAN's checksum are we doing? that one. 🌈

🌸 DESCRIPTION 🌸

okay so for the details about the computation, this page is literally telling you to go read the documentation for batadv_tt_global_crc. not me gatekeeping the algorithm 😭 — it's just that the global one already explains it, so go read that, bestie. the local one is the sibling, the lore is shared.

⭐ RETURN ⭐

the checksum of the local table 💫

that's it. that's what you get back. no surprises, no drama, just a checksum. slay.

👑 SEE ALSO 👑

bestie. sit down. hydrate. because this list is LONG and every single one of these matters. it's basically the whole translation-table.c friend group:

Kernel file ./net/batman-adv/translation-table.c

like I said. the whole friend group. every single one of them 💀

and that's the page, bestie! no warnings, no deprecated flags, nothing spooky on this one — just a checksum function and its extremely extroverted SEE ALSO section 🧚

and finally, the cute sign-off: this one lives in the kernel source tree at ./net/batman-adv, and it's dated October 2026. go forth and checksum, bestie 💜✨
