3.2.4.15 Application Requests Applying Quota Information

  • Artículo

The application provides:

  • A handle to the Open identifying a directory.

  • A list of SIDs (as specified in [MS-DTYP] section 2.4.2) for which quota information is to be applied.

  • For each SID, the quota warning threshold and quota limit to be applied, as specified in [MS-FSCC] section 2.4.40.

If the handle is invalid, or if no Open referenced by the handle is found, the client MUST return an implementation-specific error code. If the handle is valid and Open is found, the client MUST proceed as follows.

For the specified Open, the client MUST select a connection as specified in section 3.2.4.1.7. If no connection is available, the client MUST fail the set operation.

Otherwise, the client initializes an SMB2 SET_INFO Request, following the syntax specified in section 2.2.37. The SMB2 header MUST be initialized as follows:

  • The Command field is set to SMB2 SET_INFO.

  • The MessageId field is set as specified in section 3.2.4.1.3.

  • The SessionId field is set to Open.TreeConnect.Session.SessionId.

  • The TreeId field is set to Open.TreeConnect.TreeConnectId.

The SMB2 SET_INFO Request MUST be initialized as follows:

  • The InfoType field is set to SMB2_0_INFO_QUOTA.

  • The FileInfoClass field is set to 0.

  • The AdditionalInformation is set to 0.

  • The FileId field is set to Open.FileId.

  • The Buffer field is set to one or more FILE_QUOTA_INFORMATION structures, as specified in [MS-FSCC] section 2.4.40.

    • The NextEntryOffset field is set to the offset, in bytes, to the next FILE_QUOTA_INFORMATION structure, or zero if this is the last structure in the buffer.

    • The Sid field is set to the application-provided SID, in little-endian binary format as specified in [MS-DTYP] section 2.4.2.2.

    • The SidLength field is set to the length of the Sid field, in bytes.

    • The ChangeTime field is set to the current time, as specified in [MS-DTYP] section 2.3.3.

    • The QuotaUsed field is ignored and can be set to any value.

    • The QuotaThreshold field is set to the application provided quota warning threshold.

    • The QuotaLimit field is set to the application provided quota limit.

  • The BufferLength is set to the length, in bytes, of the Buffer field. A BufferLength exceeding Connection.MaxTransactSize will be rejected by the server.

  • The BufferOffset is set to the offset to the Buffer, in bytes, from the beginning of the SMB2 header.

The request MUST be sent to the server.
