      sym53c8xx_2: Set DID_REQUEUE return code when aborting squeue · fd1232b2
      Mikulas Patocka 提交于
      This patch fixes I/O errors with the sym53c8xx_2 driver when the disk
      returns QUEUE FULL status.
      
      When the controller encounters an error (including QUEUE FULL or BUSY
      status), it aborts all not yet submitted requests in the function
      sym_dequeue_from_squeue.
      
      This function aborts them with DID_SOFT_ERROR.
      
      If the disk has full tag queue, the request that caused the overflow is
      aborted with QUEUE FULL status (and the scsi midlayer properly retries
      it until it is accepted by the disk), but the sym53c8xx_2 driver aborts
      the following requests with DID_SOFT_ERROR --- for them, the midlayer
      does just a few retries and then signals the error up to sd.
      
      The result is that disk returning QUEUE FULL causes request failures.
      
      The error was reproduced on 53c895 with COMPAQ BD03685A24 disk
      (rebranded ST336607LC) with command queue 48 or 64 tags.  The disk has
      64 tags, but under some access patterns it return QUEUE FULL when there
      are less than 64 pending tags.  The SCSI specification allows returning
      QUEUE FULL anytime and it is up to the host to retry.

      drivers: net: xen-netfront: fix array initialization bug · 810d8ced
      Vincenzo Maffione 提交于
      This patch fixes the initialization of an array used in the TX
      datapath that was mistakenly initialized together with the
      RX datapath arrays. An out of range array access could happen
      when RX and TX rings had different sizes.
