      scsi: scsi_debug: Fix memory leak on module unload · 52ab9768
      Luis Henriques authored
      Since commit 80c49563 ("scsi: scsi_debug: implement IMMED bit") there
      are long delays in F_SYNC_DELAY and F_SSU_DELAY.  This can cause a memory
      leak in schedule_resp(), which can be invoked while unloading the
      scsi_debug module: free_all_queued() had already freed all sd_dp and
      schedule_resp will alloc a new one, which will never get freed.  Here's the
      kmemleak report while running xfstests generic/350:
      
      unreferenced object 0xffff88007d752b00 (size 128):

      scsi: ipr: Eliminate duplicate barriers · f2233a33
      Arnd Bergmann authored
      Driver does both wmb() and writel(). The latter already has a barrier
      on some architectures like arm64. This ends up with CPU observing two
      barriers back to back before executing the register write.
      
      Drivers should generally assume that the barrier implied by writel() is
      sufficient for ordering DMA. Remove the extraneous wmb() before it.

      scsi: target: tcmu: add read length support · 6c3796d1
      bstroesser@ts.fujitsu.com authored
      Generally target core and TCMUser seem to work fine for tape devices and
      media changers.  But there is at least one situation where TCMUser is not
      able to support sequential access device emulation correctly.
      
      The situation is when an initiator sends a SCSI READ CDB with a length that
      is greater than the length of the tape block to read. We can distinguish
      two subcases:
      
      A) The initiator sent the READ CDB with the SILI bit being set.
      
         In this case the sequential access device has to transfer the data from
         the tape block (only the length of the tape block) and transmit a good
         status.  The current interface between TCMUser and the userspace does
         not support reduction of the read data size by the userspace program.
      
         The patch below fixes this subcase by allowing the userspace program to
         specify a reduced data size in read direction.
      
      B) The initiator sent the READ CDB with the SILI bit not being set.
      
         In this case the sequential access device has to transfer the data from
         the tape block as in A), but additionally has to transmit CHECK
         CONDITION with the ILI bit set and NO SENSE in the sensebytes. The
         information field in the sensebytes must contain the residual count.
      
         With the below patch a user space program can specify the real read data
         length and appropriate sensebytes.  TCMUser then uses the se_cmd flag
         SCF_TREAT_READ_AS_NORMAL, to force target core to transmit the real data
         size and the sensebytes.  Note: the flag SCF_TREAT_READ_AS_NORMAL is
         introduced by Lee Duncan's patch "[PATCH v4] target: transport should
         handle st FM/EOM/ILI reads" from Tue, 15 May 2018 18:25:24 -0700.
