okay so bestie, welcome to the Kernel API Manual entry for ksmbd_sign_smb2_pdu(9) — and yes, the "9" means it's a kernel function page, iykyk 🎀

💫 NAME 💫

ksmbd_sign_smb2_pdu — the function that generates packet signing 🔏✨

like, it's the little guy responsible for making the signature so everyone knows the packet is legit and not sus 💅

---

🦋 SYNOPSIS 🦋

void ksmbd_sign_smb2_pdu (struct ksmbd_conn *conn , char *key , struct
kvec *iov , int n_vec , char *sig );

no cap, that's the whole signature-slinging lineup right there 👑

🌸 ARGUMENTS 🌸

• conn — the connection 🫶 like, the actual link we're doing all this signing for
• key — the signing key 🔑 the sacred little secret that makes the crypto happen
• iov — buffer iov array 📦 a whole lineup of buffers, very iovec-coded of it
• n_vec — number of iovecs 🔢 literally just how many of those buffer things are in the array
• sig — signature value generated for client request packet ✍️💖 the final product, the signed-and-sealed moment, the main character of this whole function fr fr
