Valid SMB Requests by Negotiated Dialect

The following SMB messages may be exchanged by CIFS clients and servers if the "PC NETWORK PROGRAM 1.0" dialect is negotiated:

`SMB_COM_CREATE_DIRECTORY`	`SMB_COM_DELETE_DIRECTORY`
`SMB_COM_OPEN`	`SMB_COM_CREATE`
`SMB_COM_CLOSE`	`SMB_COM_FLUSH`
`SMB_COM_DELETE`	`SMB_COM_RENAME`
`SMB_COM_QUERY_INFORMATION`	`SMB_COM_SET_INFORMATION`
`SMB_COM_READ`	`SMB_COM_WRITE`
`SMB_COM_LOCK_BYTE_RANGE`	`SMB_COM_UNLOCK_BYTE_RANGE`
`SMB_COM_CREATE_TEMPORARY`	`SMB_COM_CREATE_NEW`
`SMB_COM_CHECK_DIRECTORY`	`SMB_COM_PROCESS_EXIT`
`SMB_COM_SEEK`	`SMB_COM_TREE_CONNECT`
`SMB_COM_TREE_DISCONNECT`	`SMB_COM_NEGOTIATE`
`SMB_COM_QUERY_INFORMATION_DISK`	`SMB_COM_SEARCH`
`SMB_COM_OPEN_PRINT_FILE`	`SMB_COM_WRITE_PRINT_FILE`
`SMB_COM_CLOSE_PRINT_FILE`	`SMB_COM_GET_PRINT_QUEUE`

If the "LANMAN 1.0" dialect is negotiated, all of the messages in the previous list must be supported. Clients negotiating LANMAN 1.0 and higher dialects will probably no longer send SMB_COM_PROCESS_EXIT, and the response format for SMB_COM_NEGOTIATE is modified as well. New messages introduced with the LANMAN 1.0 dialect are:

`SMB_COM_LOCK_AND_READ`	`SMB_COM_WRITE_AND_UNLOCK`
`SMB_COM_READ_RAW`	`SMB_COM_READ_MPX`
`SMB_COM_WRITE_MPX`	`SMB_COM_WRITE_RAW`
`SMB_COM_WRITE_COMPLETE`	`SMB_COM_WRITE_MPX_SECONDARY`
`SMB_COM_SET_INFORMATION2`	`SMB_COM_QUERY_INFORMATION2`
`SMB_COM_LOCKING_ANDX`	`SMB_COM_TRANSACTION`
`SMB_COM_TRANSACTION_SECONDARY`	`SMB_COM_IOCTL`
`SMB_COM_IOCTL_SECONDARY`	`SMB_COM_COPY`
`SMB_COM_MOVE`	`SMB_COM_ECHO`
`SMB_COM_WRITE_AND_CLOSE`	`SMB_COM_OPEN_ANDX`
`SMB_COM_READ_ANDX`	`SMB_COM_WRITE_ANDX`
`SMB_COM_SESSION_SETUP_ANDX`	`SMB_COM_TREE_CONNECT_ANDX`
`SMB_COM_FIND`	`SMB_COM_FIND_UNIQUE`
`SMB_COM_FIND_CLOSE`

The "LM1.2X002" dialect introduces these new SMBs:

`SMB_COM_TRANSACTION2`	`SMB_COM_TRANSACTION2_SECONDARY`
`SMB_COM_FIND_CLOSE2`	`SMB_COM_LOGOFF_ANDX`

"NT LM 0.12" dialect introduces:

`SMB_COM_NT_TRANSACT`	`SMB_COM_NT_TRANSACT_SECONDARY`
`SMB_COM_NT_CREATE_ANDX`	`SMB_COM_NT_CANCEL`
`SMB_COM_NT_RENAME`	`SMB_COM_READ_BULK`
`SMB_COM_WRITE_BULK`	`SMB_COM_WRITE_BULK_DATA`
