batadv_forw_packet_alloc(9)

💅 batadv_forw_packet_alloc(9) — the kernel API manual, but make it make sense

okay bestie, welcome to the Kernel API Manual entry for batadv_forw_packet_alloc(9) ✨ this is a 9-section manual page and we are reading all of it, no skimming, no cap 🫶

---

🌸 NAME 🌸

batadv_forw_packet_alloc — allocate a forwarding packet 🎀

---

✨ SYNOPSIS ✨

struct batadv_forw_packet * batadv_forw_packet_alloc (struct
batadv_hard_iface *if_incoming , struct batadv_hard_iface *if_outgoing ,
atomic_t *queue_left , struct batadv_priv *bat_priv , struct sk_buff
*skb );

like, that's the whole signature, it's giving "five arguments and a dream" 😭💖

---

🦋 ARGUMENTS 🦋

• if_incoming — the (optional) if_incoming that's gonna get grabbed 👀
• if_outgoing — the (optional) if_outgoing that's also gonna get grabbed
• queue_left — the (optional) queue counter that's gonna get decreased, bestie
• bat_priv — the bat_priv for the mesh that this forw_packet belongs to 🌈
• skb — the raw packet that this forwarding packet is supposed to contain ⭐

---

💜 DESCRIPTION 💜

So here's the vibe: this thing allocates a forwarding packet, and it tries to get a reference to the (optional) if_incoming, if_outgoing, and queue_left. That's three optionals, she's flexible 💅

And here's the little detail you do NOT wanna miss: if queue_left is NULL, then bat_priv is optional too. periodt 🎀

---

🔥 RETURN 🔥

• an allocated forwarding packet on success 🥳
• NULL otherwise 💀

okay this list is LONG and she ate, every single one of these, no skipping 🧚
