💖 ksmbd_sign_smb3_pdu(9) 💖

Okay so bestie, welcome to the Kernel API Manual — this is the page for ksmbd_sign_smb3_pdu, and it's literally the function that handles packet signing generation. Short page, but she's important, so let's get into it 🫶

---

✨ NAME ✨

ksmbd_sign_smb3_pdu — the function whose whole job is generating packet signing. That's it, that's the vibe 💅

---

🦋 SYNOPSIS 🦋

void ksmbd_sign_smb3_pdu (struct ksmbd_conn *conn , char *key , struct
       kvec *iov , int n_vec , char *sig );

Returns void, so like… she does the work and doesn't report back. Iconic, honestly.

---

🎀 ARGUMENTS 🎀

Here's the whole cast of characters, no skips:

• conn — the connection. The main character of this whole situation 🔥
• key — the signing key. Guard it with your life, ngl 🔑
• iov — the buffer iov array. Your little lineup of buffers 🌈
• n_vec — number of iovecs in that array. Counting matters, bestie ✨
• sig — the signature value generated for the client request packet. The grand finale, the reveal, the moment 👑

Lowkey a warning from your girl: this page only tells you the signature and the args. For the actual behaviour, go read the source at ./fs/smb/server/auth.c — iykyk 🙈
