New Revision: 346953
URL: http://svnweb.freebsd.org/changeset/ports/346953
QAT: https://qat.redports.org/buildarchive/r346953/

Log:
  Improve the FreeBSD SCSI and SAS support in smartmontools:
  - Remove unused private fields from some classes (found by Clang).
  - In freebsd_scsi_device::scsi_pass_through:
    * Make sure this function returns false on error instead of an error
      code that gets converted to true.
    * Put printing of the "Incoming data" debug info right after the
      cam_send_ccb() call and before the error checking to make
      debugging easier.
    * When copying sense data make sure the fields in the CCB are
      actually valid with CAM_AUTOSNS_VALID.  Also make sure that the
      size of the sense data doesn't overflow max_sense_len.  This was
      the real cause for the crash in ports/181836.
    * Add some debug printing on the sense data.
  
  Committed upstream as r3873.
