Expected output for IOCTL_BIOMETRIC_CONNECT_SECURE RRS feed

  • Question

  • Hello,

    Referring to https://github.com/Microsoft/SecureDeviceConnectionProtocol new biometric IOCTL where added to Windows 1804.

    The SDCP wiki documentation indicates IOCTL_BIOMETRIC_CONNECT_SECURE will be added to WBF and the expected output is WINBIO_SECURE_CONNECTION_RESPONSE which nests WINBIO_SECURE_CONNECTION_DATA.

    However, after updating WDK and looking at the updated winbio headers for RS4, there is no structure WINBIO_SECURE_CONNECTION_RESPONSE defined.

    So, what does the framework really expects? WINBIO_SECURE_CONNECTION_RESPONSE or WINBIO_SECURE_CONNECTION_DATA?

    If the later, as there is no WinBioHresult field, how to report a failure in case the request to the device was unsuccessful?

    Thank you!
