batadv_transtable_best_orig(9)

💅 batadv_transtable_best_orig(9) ✨

okay so this is a page from the Kernel API Manual bestie — like, kernel-internal docs, man section 9, the whole thing. it's about batadv_transtable_best_orig, and no cap it's a tiny little function but it does something genuinely important. let's get into it 🫶

---

🌸 NAME 🌸

batadv_transtable_best_orig — literally just "Get best originator list entry from tt entry" 💖 that's it, that's the whole vibe. it goes into a translation table entry and pulls out the best originator list entry it can find. slay.

---

✨ SYNOPSIS ✨

struct batadv_tt_orig_list_entry * batadv_transtable_best_orig (struct
batadv_priv *bat_priv , struct batadv_tt_global_entry *tt_global_entry
);

like, copy-paste the signature exactly pls, no typos, she's picky about that 🔥

---

🎀 ARGUMENTS 🎀

• bat_priv — the bat priv with all the mesh interface information. like yes that's the one, it's carrying every single detail about the mesh interface, main character behaviour honestly 👑
• tt_global_entry — the global translation table entry that's about to be analyzed. this is the thing getting the vibe check 🦋

---

💀 DESCRIPTION 💀

okay so this is the important bit and i need you to actually read it:

this function assumes the caller holds rcu_read_lock.

like, fr fr. it's not a suggestion, it's a precondition — the caller has to already be holding rcu_read_lock when they call this. not me warning you about locking discipline, but here we are 😭 don't come crying to me when the locking is wrong, i told you 💅

---

🌈 RETURN 🌈

it returns the best originator list entry, or NULL on errors. that's the whole deal. if it works, you get the entry; if it doesn't, NULL and you deal with it 🙈

okay bestie, this list is long. like, absurdly long. this function lives in the same kernel file — ./net/batman-adv/translation-table.c — as literally everyone else in this clique, and here's the whole squad, every single one of them, no skipping 👑✨
