      [SCSI] update spi transport class so that u320 Domain Validation works · 9a8bc9b8
      James Bottomley authored
      There are several extra things that have to be considered when running
      Domain Validation on a u320 target (notably how you fall back).
      
      Hopefully this should help us when someone adds this transport class to
      aic79xx.
      
      I've tested this on the lsi1030, so I know it works correctly up to
      u320.

      James Bottomley authored
      For setting coupled parameters, we need to be comparing against the goal
      settings, not the current ones.

      [SCSI] sg: Command completion after remove oops · 521314c1
      brking@us.ibm.com authored
      A problem exists todayin the sg driver that if an SG_IO request is
      outstanding to a device when it is removed from the system. The
      system may oops if that command completes later in time.
      
      1. sg_remove gets called
      2. sg_remove calls sg_finish_req_req on all pending requests
         This removes the Sg_request's from the headrp list in the Sg_fd
      3. The sleeping SG_IO ioctl is woken. It does nothing and returns.
      4. The caller closes the fd, which invokes sg_release
      5. sg_release calls sg_remove_sfp. It finds no outstanding commands
         since the headrp list is empty, so it calls __sg_remove_sfp,
         which frees the sfp.
      6. Now when sg_cmd_done gets called, sg uses upper_private_data in
         the Scsi_Request, which should point to the srp, which has been
         freed, so it points to freed memory.
      7. sg then dereferences the srp pointer to get the sfp, and we oops.
      
      The fix is to NULL out the upper_private_data field in this path,
      which sg_cmd_done already checks for, which will prevent the oops
      from occurring.
