---

🌸 SYNOPSIS 🌸

void rxrpc_kernel_query_challenge (struct sk_buff *challenge , struct
rxrpc_peer **_peer , unsigned long *_peer_appdata , u16 *_service_id ,
u8 *_security_index );

like... it returns void, so don't go looking for a return value, there isn't one 🙈 it just fills in your out-params.

🎀 ARGUMENTS 🎀

• challenge — the challenge you wanna query, bestie. this is the thing you're interrogating 💅
• _peer — the spot where the peer record gets handed back to you 👑
• _peer_appdata — the application data that's attached to a peer record 🍓
• _service_id — where the connection service ID comes back to live 💖
• _security_index — and here's where the connection security index gets returned ✨

🔥 DESCRIPTION 🔥

the whole vibe: you take a CHALLENGE message and you extract the useful parameters out of it. that's it, that's the function. no cap, it's giving "small but mighty" 🧚
