scsi: aacraid: Use correct function to get ctrl health

2017-06-13T00:48:00Z

The command thread checks the ctrl health periodically before sending updates to the controller. The function that it uses is aac_check_health which does more than get the health status. Signed-off-by: Raghava Aditya Renukunta Reviewed-by: David Carroll Signed-off-by: Martin K. Petersen

scsi: aacraid: Fix DMAR issues with iommu=pt

2017-06-13T00:47:59Z

The driver changed the DMA consistent map after consistent memory was allocated, this invalidated the IOMMU identity mapping. The fix was to make sure that we set the DMA consistent mask setting once depending on the controller card. Signed-off-by: Raghava Aditya Renukunta Reviewed-by: Dave Carroll Signed-off-by: Martin K.

scsi: aacraid: fix PCI error recovery path

2017-04-12T00:45:59Z

During a PCI error recovery, if aac_check_health() is not aware that a PCI error happened and we have an offline PCI channel, it might trigger some errors (like NULL pointer dereference) and inhibit the error recovery process to complete. This patch makes the health check procedure aware of PCI channel issues, and in case of error recovery process, the function aac_adapter_check_health() returns -1 and let the recovery process to complete successfully. This patch was tested on upstream kernel v4.11-rc5 in PowerPC ppc64le architecture with adapter 9005:028d (VID:DID) - the error recovery procedure was able to recover fine.

scsi: aacraid: Fix potential null access

2017-03-15T23:00:36Z

Currently, command threads fails to return ioctls commands for older controller versions, since it returns when all the fibs have been allocated. Another issue is even all the fibs have not been allocated, the correct allocated fibs is not updated nor freed.

scsi: aacraid: remove redundant zero check on ret

2017-02-28T03:19:43Z

The check for ret being zero is redundant as a few statements earlier we break out of the while loop if ret is non-zero. Thus we can remove the zero check and also the dead-code non-zero case too.
