batadv_bla_get_backbone_gw(9)

💅 batadv_bla_get_backbone_gw — the "find it or make it" girlie of bridge loop avoidance

okay so bestie, welcome to the batadv_bla_get_backbone_gw(9) page 💖 this is a Kernel API Manual moment and honestly the whole thing is about one job: you hand it some stuff, and it either finds you a backbone gateway or creates one for you. lowkey iconic. literally a find-or-create. slay.

---

✨ NAME ✨

batadv_bla_get_backbone_gw — finds or creates a backbone gateway 🫶

---

🌸 SYNOPSIS 🌸

struct batadv_bla_backbone_gw * batadv_bla_get_backbone_gw (struct
batadv_priv *bat_priv , const u8 *orig , unsigned short vid , bool
own_backbone );

that's the whole signature, no cap — four args in, a struct batadv_bla_backbone_gw * out 👑

---

🎀 ARGUMENTS 🎀

• bat_priv — the bat priv with all the mesh interface information. it's giving "main character data structure", it's got the whole mesh interface tea in it 🦋
• orig — the mac address of the originator. const u8 * bestie, so don't you dare go writing through it 💅
• vid — the VLAN ID. unsigned short energy ✨
• own_backbone — set if the requested backbone is local. like, is this backbone ours? set the bool, tell the truth 🙈

---

⭐ RETURN ⭐

the (possibly created) backbone gateway — or NULL on error 😭

heads up: that "possibly created" is doing a LOT of work in that sentence. this function might genuinely be over here conjuring a backbone gateway out of thin air for you. and if things go sideways you get NULL, so vibe check before you dereference, fr fr 💀
