ksmbd_auth_ntlmv2(9)

💖 NAME 💖

Okay bestie, welcome to ksmbd_auth_ntlmv2(9) from the Kernel API Manual — this is literally the NTLMv2 authentication handler. No cap, that's the whole vibe of this one. ✨

✨ SYNOPSIS ✨

Here's the signature, copied exactly because we do not mess with code:

int ksmbd_auth_ntlmv2 (struct ksmbd_conn *conn , struct ksmbd_session
       *sess , struct ntlmv2_resp *ntlmv2 , int blen , char *domain_name , char
       *cryptkey , char *sess_key );

🎀 ARGUMENTS 🎀

• conn — the connection. It's giving “which connection are we on” energy.
• sess — the session of the connection. Bestie, it's the session belonging to the connection.
• ntlmv2 — the NTLMv2 challenge response. Iconic.
• blen — the NTLMv2 blob length. Yes, the length of the NTLMv2 blob.
• domain_name — the domain name. Simple, clean, slay.
• cryptkey — the session crypto key. Keep it safe.
• sess_key — the derived session key output buffer. She's an output buffer, so treat her right.

🌈 RETURN 🌈

It returns 0 on success, and an error number on error. That's it. Periodt. ✅
