2.2.38 SMB2 QUERY_INFO Response

The SMB2 QUERY_INFO Response packet is sent by the server in response to an SMB2 QUERY_INFO Request packet. This response consists of an SMB2 header, as specified in section 2.2.1, followed by this response structure.

StructureSize (2 bytes): The server MUST set this field to 9, indicating the size of the request structure, not including the header. The server MUST set this field to this value regardless of how long Buffer[] actually is in the request being sent.

OutputBufferOffset (2 bytes): The offset, in bytes, from the beginning of the SMB2 header to the information being returned.

OutputBufferLength (4 bytes): The length, in bytes, of the information being returned.

Buffer (variable): A variable-length buffer that contains the information that is returned in the response, as described by the OutputBufferOffset and OutputBufferLength fields. Buffer format depends on InfoType and AdditionalInformation, as follows.

InfoType	AdditionalInformation	Buffer format specification
SMB2_0_INFO_FILE	The value depends on FileInfoClass, as specified in section 2.2.37.	See [MS-FSCC] section 2.4. For FileFullEaInformation, the server MUST return the list of extended attributes (EA) that will fit in the Buffer, beginning with the attribute whose index is specified by the AdditionalInformation field of the request. The size of the returned buffer is equal to the size of the EA entries that are returned.
SMB2_0_INFO_FILESYSTEM	0	See [MS-FSCC] section 2.5.
SMB2_0_INFO_SECURITY	Any combination of the values: OWNER_SECURITY_INFORMATION GROUP_SECURITY_INFORMATION LABEL_SECURITY_INFORMATION DACL_SECURITY_INFORMATION SACL_SECURITY_INFORMATION ATTRIBUTE_SECURITY_INFORMATION SCOPE_SECURITY_INFORMATION BACKUP_SECURITY_INFORMATION	The security descriptor data structure, as specified in [MS-DTYP] section 2.4.6, populated with the data specified by the AdditionalInformation value.
SMB2_0_INFO_QUOTA	0	See [MS-FSCC] section 2.4.40.
