smb2_is_sign_req(9)

💅 smb2_is_sign_req(9) 💅

okay so bestie, welcome to the Kernel API Manual — this one's smb2_is_sign_req(9), and honestly? lowkey iconic. it's a tiny little handler whose whole personality is checking whether a packet is signed. that's it. that's the job. slay. 🎀

---

✨ NAME ✨

smb2_is_sign_req — the handler for checking packet signing status 🦋

---

✨ SYNOPSIS ✨

bool smb2_is_sign_req (struct ksmbd_work *work , unsigned int command );

like, it takes a ksmbd_work and a command id and hands you back a bool. simple. clean. no cap. ✨

---

✨ ARGUMENTS ✨

• work — the smb work that's holding the notify command buffer 🫶
• command — the SMB2 command id 👑

---

✨ RETURN ✨

returns true if packed is signed, and false otherwise 💖

ngl the original says "packed" — not my typo, I'm just the messenger 😭
