3.3.5.21.2 Handling SMB2_0_INFO_FILESYSTEM

The information classes that are supported for setting underlying object store information are listed in section 2.2.39. Documentation for these is provided [MS-FSCC] section 2.5. Requests for information classes not listed in section 2.2.39 but documented in section 2.5 of [MS-FSCC] for Uses of "Set" or "LOCAL" MUST be failed with STATUS_NOT_SUPPORTED. Requests for information classes not documented in section 2.5 of [MS-FSCC] or documented in section 2.5 of [MS-FSCC] for Uses of only "Query" MUST be failed with STATUS_INVALID_INFO_CLASS.

If the object store supports security and the information class is FileFsControlInformation or FileFsObjectIdInformation and Open.GrantedAccess does not include FILE_WRITE_DATA, the server MUST fail the request with STATUS_ACCESS_DENIED.

The server MUST apply the information requested to the underlying object store.<427> If the underlying object store returns an error, the server MUST fail the request with the error code received. Otherwise, the server MUST initialize an SMB2 SET_INFO Response following the syntax given in section 2.2.40. The response MUST then be sent to the client.
