✨ NAME ✨

okay so bestie, welcome to ovpn_opcode_compose(9) from the Kernel API Manual 💖 this one is literally about combining an OP code, a key ID, and a peer ID into wire format. slay.

🎀 SYNOPSIS 🎀

u32 ovpn_opcode_compose (u8 opcode , u8 key_id , u32 peer_id );

no cap, that's the whole signature 🫶

🌸 ARGUMENTS 🌸

• opcode — the OP code ✨
• key_id — the key ID 🔑
• peer_id — the peer ID 👯

🦋 RETURN 🦋

it gives you back a 4 bytes integer obtained by combining all the input values following the OpenVPN wire format. then you can write that integer to the packet header. periodt 💅

• Kernel file ./drivers/net/ovpn/proto.h
• ovpn_opcode_from_skb(9)
• ovpn_peer_id_from_skb(9)
• ovpn_key_id_from_skb(9)

💜 bestie, that's the whole vibe: opcode + key_id + peer_id go in, a wire-format u32 comes out, and it's ready for the packet header. iconic.
