batadv_tt_local_valid(9)

📦 version 7.3.1, in nixpkgs unstable

💖 batadv_tt_local_valid — like, the vibe check for your local TT entry 💖

Okay so bestie, this page is batadv_tt_local_valid(9) from the Kernel API Manual — yes, the whole thing lives in ./net/batman-adv and it's dated October 2026 (we love a future queen ⏳✨). Anyway, let's get into it.

✨ NAME ✨

batadv_tt_local_valid — verify local tt entry and get flags

Like, the actual job description is literally right there. It checks the thing, and it hands you the flags. Two-for-one, slay.

🦋 SYNOPSIS 🦋

bool batadv_tt_local_valid (const void *entry_ptr , const void *data_ptr
, u8 *flags );

That's the whole signature. Note the return type is bool — no cap, it's a yes-or-no situation — and the params are two const void * pointers plus a u8 * for the flags. Copy it exactly if you're typing it out, bestie, because const void * is not a suggestion 💅

🎀 ARGUMENTS 🎀

  • entry_ptr — the local tt entry that's, like, getting checked. This is the main character here 👑
  • data_ptr — not used! Like at all! It's only there because the callback prototype requires it. So don't stress about it, it's just filling a seat so the signature works. Fr fr 🙈
  • flags — a pointer where the TT flags for this client get stored. It's the output slot, the lil gift bag, the place the answer goes 🎁

🌸 DESCRIPTION 🌸

So what it does: it checks whether the given local TT entry is valid. Checks the validity. That's the whole assignment.

And if it is valid — then the flags pointer you handed it gets updated. So like, valid entry → flags written → everyone's happy 🫶 If it's not valid, no flags for you, and the return value tells you which way it went.

⭐ RETURN ⭐

  • true — the entry is valid 💚
  • false — otherwise, bestie 😭

That's the entire return contract. true if the entry is a valid, false otherwise. Simple, iconic, no notes.

Heads up: the original says "true if the entry is a valid, false otherwise" — that's the actual wording, so I'm passing it to you as-is. Don't come for me 💀

🌈 SEE ALSO 🌈

Okay so this part is long. Like, genuinely long. This function is in ./net/batman-adv/translation-table.c and apparently knows literally everyone at this party. Here's the full guest list, in order, no skips, no cuts — I would never do that to you:

One hundred and three. I counted. Okay maybe I didn't count but it's a lot and I listed every single one, periodt 💅✨ (and yes, _batadv_tt_global_del_orig_entry(9), _batadv_is_ap_isolated(9) and _batadv_tt_update_changes(9) keep their leading underscores — do not strip the underscore, bestie, that's a whole different function 😤)

Sign-off time, my love 🫶 this page is filed under ./net/batman-adv, stamped October 2026, comes from the Kernel API Manual, and answers to the name batadv_tt_local_valid(9). Go check your entries, stay valid, and hydrate 💧🧚
