From 9fbc590860e75785bdaf8b83e48fabfe4d4f7d58 Mon Sep 17 00:00:00 2001 From: Steve French Date: Fri, 20 Aug 2010 20:42:26 +0000 Subject: [CIFS] Fix ntlmv2 auth with ntlmssp Make ntlmv2 as an authentication mechanism within ntlmssp instead of ntlmv1. Parse type 2 response in ntlmssp negotiation to pluck AV pairs and use them to calculate ntlmv2 response token. Also, assign domain name from the sever response in type 2 packet of ntlmssp and use that (netbios) domain name in calculation of response. Enable cifs/smb signing using rc4 and md5. Changed name of the structure mac_key to session_key to reflect the type of key it holds. Use kernel crypto_shash_* APIs instead of the equivalent cifs functions.
