Issue: qla4xxx Unable to clear DDB indices when logout fails due to failure of connection close mbox command. Root cause: If login to session fail, iscsiadm make call to destroy_session. qla4xxx driver does not free ddb index map before free_ddb() Fix: Clear DDB Index map before free_ddb in "destroy_session" in case of connection close mailbox command failure with 4005h.

Issue: For ISP8xxx, adapter initialization is not retried if qla4xxx_initialize_adapter fails. Fix: If qla4xxx_initialize_adapter fails, first check if failure is due to IRQs not attached in order to skip retrial, then free the IRQs and then retry initializing the adapter. Signed-off-by:

In iSCSI Boot scenario, when machine is reboot/shutdown phase the active sessions are not closed. Driver queue cleanup is done as part of unload and device is disabled. Sessions are still active, iSCSI commands are issued from session which comes to driver, as driver cleanup and device disabled there is kernel stack dump with errors. Fix is invoking iscsi_session_failure with ISCSI_ERR_INVALID_HOST on all the active sessions when shutdown routine is called. Signed-off-by:

When an MBX command timeout happens,the resources associated with the MBX command were freed. If FW were to give the response to host after the timeout value set by driver then driver crashes as the MBX Cmd resources were already freed. This patch fixes this issue by maintaing a state flag for each of the MBX command posted/timedout/completed. Signed-off-by:

Do no rescan on every events -- way too many rescans are triggered if we don't filter the events. Limit rescans to be triggered by the following set of events: * controller state change * enclosure hot plug * physical drive state change * logical drive state change * redundant controller state change * accelerated io enabled/disabled * accelerated io configuration change Signed-off-by:

Add controller-based data-at-rest encryption compatibility to ioaccel2 path (HP SSD Smart Path). Encryption feature requires driver to supply additional fields for encryption enable, tweak index, and data encryption key index in the ioaccel2 request structure. Encryption enable flag and data encryption key index come from raid_map data structure from raid offload command. During ioaccel2 submission, check device structure's raid map to see if encryption is enabled for the device. If so, call new function below. Add function set_encrypt_ioaccel2 to set encryption flag, data encryption key index, and calculate tweak value from request's logical block address. Signed-off-by:

Allow driver to schedule a rescan whenever a request fails on the ioaccel2 path. This eliminates the possibility of driver getting stuck in non-ioaccel mode. IOaccel mode (HP SSD Smart Path) is disabled by driver upon error detection. Driver relied on idea that request would be retried through normal path, and a subsequent error would occur on that path, and be processed by controller firmware. As part of that process, controller disables ioaccel mode and later reinstates it, signalling driver to change modes. In some error cases, the error will not duplicate on the standard path, so the driver could get stuck in non-ioaccel mode. To avoid that, we allow driver to request a rescan during the next run of the rescan thread. Signed-off-by:

Allow SSD Smart Path for a controller to be disabled by the user, regardless of settings in controller firmware or array configuration. To disable: echo 0 > /sys/class/scsi_host/host<id>/acciopath_status To re-enable: echo 1 > /sys/class/scsi_host/host<id>/acciopath_status To check state: cat /sys/class/scsi_host/host<id>/acciopath_status Signed-off-by:
