2016-09-14scsi: hisi_sas: set dma mask before allocate DMA memoryJohn Garry
The device DMA mask was being set after the bulk of the DMA allocations in the driver init, so potentially DMA allocates fail. To resolve, relocate before allocating the DMA memory when initialising the driver.

2016-09-14scsi: hisi_sas: fix a potential warning for sata disk ejectionJohn Garry
If hisi_sas_task_prep() fails for a SATA device due to PHY down, we return a failure to libata and also call task_done(), which will cause ata_qc_complete() to be called twice: - first call from hisi_sas_task_prep(), which will clear flag ATA_QCFLAG_ACTIVE - ata_qc_complete() called from libata The warning call trace is as follows: [ 117.070206] [<ffff0000084f59b0>] __ata_qc_complete+0xf4/0x11c [ 117.070208] [<ffff0000084f5b58>] ata_qc_complete+0x180/0x200 [ 117.070210] [<ffff0000084f5dd0>] ata_qc_issue+0x110/0x354 [ 117.070212] [<ffff0000084f6254>] ata_exec_internal_sg+0x240/0x4d0 [ 117.070214] [<ffff0000084f6544>] ata_exec_internal+0x60/0xa0 [ 117.070217] [<ffff000008501580>] ata_read_log_page+0x188/0x1b4 [ 117.070218] [<ffff0000085017dc>] ata_eh_analyze_ncq_error+0xa8/0x274 [ 117.070220] [<ffff000008501a3c>] ata_eh_link_autopsy+0x94/0x8c8 [ 117.070222] [<ffff0000085022a4>] ata_eh_autopsy+0x34/0xe8 [ 117.070223] [<ffff00000850540c>] ata_do_eh+0x28/0xc0 [ 117.070225] [<ffff0000085054e0>] ata_std_error_handler+0x3c/0x84 [ 117.070227] [<ffff000008505140>] ata_scsi_port_error_handler+0x480/0x674 [ 117.070230] [<ffff0000084e3020>] async_sas_ata_eh+0x44/0x78 [ 117.070231] [<ffff0000080d6b8c>] async_run_entry_fn+0x40/0x104 [ 117.070234] [<ffff0000080ce518>] process_one_work+0x128/0x2f0 [ 117.070235] [<ffff0000080ce738>] worker_thread+0x58/0x434 [ 117.070237] [<ffff0000080d416c>] kthread+0xd4/0xe8 [ 117.070240] [<ffff000008084e10>] ret_from_fork+0x10/0x40 The issue is resolved by simply returning a failure status code to the upper layer.

2016-09-14scsi: cxlflash: Fix context reference tracking on detachMatthew R. Ochs
Commit 888baf069f49 ("scsi: cxlflash: Add kref to context") introduced a kref to the context. In particular, the detach routine was updated to use the kref services for managing the removal and destruction of a context. As part of this change, the tracking mechanism internal to the detach handler was refactored. This introduced a bug that can cause the tracking state to be lost. This can lead to a situation where exclusive access to a context is prematurely [and unknowingly] relinquished for the executing thread. To remedy, only update the tracking state when the kref operation indicates the context was removed. Fixes: 888baf069f49 ("scsi: cxlflash: Add kref to context") Signed-off-by: Matthew R.

2016-09-14scsi: cxlflash: Improve EEH recovery timeMatthew R. Ochs
When an EEH occurs during device initialization, the port timeout logic can cause excessive delays as MMIO reads will fail. Depending on where they are experienced, these delays can lead to a prolonged reset, causing an unnecessary triggering of other timeout logic in the SCSI stack or user applications. To expedite recovery, the port timeout logic is updated to decay the timeout at a much faster rate when in the presence of a likely EEH frozen event. Signed-off-by: Matthew R.

2016-09-14scsi: cxlflash: Fix to avoid EEH and host reset collisionsMatthew R. Ochs
The EEH reset handler is ignorant to the current state of the driver when processing a frozen event and initiating a device reset. This can be an issue if an EEH event occurs while a user or stack initiated reset is executing. More specifically, if an EEH occurs while the SCSI host reset handler is active, the reset initiated by the EEH thread will likely collide with the host reset thread. This can leave the device in an inconsistent state, or worse, cause a system crash. As a remedy, the EEH handler is updated to evaluate the device state and take appropriate action (proceed, wait, or disconnect host). The host reset handler is also updated to handle situations where an EEH occurred during a host reset. In such situations, the host reset handler will delay reporting back a success to give the EEH reset an opportunity to complete. Signed-off-by: Matthew R.

2016-09-09scsi: cxlflash: Remove the device cleanly in the system shutdown pathUma Krishnan
Commit 704c4b0ddc03 ("cxlflash: Shutdown notify support for CXL Flash cards") was recently introduced to notify the AFU when a system is going down. Due to the position of the cxlflash driver in the device stack, cxlflash devices are _always_ removed during a reboot/shutdown. This can lead to a crash if the cxlflash shutdown hook is invoked _after_ the shutdown hook for the owning virtual PHB. Furthermore, the current implementation of shutdown/remove hooks for cxlflash are not tolerant to being invoked when the device is not enabled. This can also lead to a crash in situations where the remove hook is invoked after the device has been removed via the vPHBs shutdown hook. An example of this scenario would be an EEH reset failure while a reboot/shutdown is in progress. To solve both problems, the shutdown hook for cxlflash is updated to simply remove the device. This path already includes the AFU notification and thus this solution will continue to perform the original intent. At the same time, the remove hook is updated to protect against being called when the device is not enabled.

2016-09-09scsi: cxlflash: Scan host only after the port is ready for I/OUma Krishnan
When a port link is established, the AFU sends a 'link up' interrupt. After the link is up, corresponding initialization steps are performed on the card. Following that, when the card is ready for I/O, the AFU sends 'login succeeded' interrupt. Today, cxlflash invokes scsi_scan_host() upon receipt of both interrupts. SCSI commands sent to the port prior to the 'login succeeded' interrupt will fail with 'port not available' error. This is not desirable. Moreover, when async_scan is active for the host, subsequent scan calls are terminated with error. Due to this, the scsi_scan_host() call performed after 'login succeeded' interrupt could portentially return error and the devices may not be scanned properly. To avoid this problem, scsi_scan_host() should be called only after the 'login succeeded' interrupt. Signed-off-by: Uma Krishnan <ukrishn@linux.vnet.ibm.com> Acked-by: Matthew R.

2016-09-02scsi: mpt: Remove deprecated create_singlethread_workqueueBhaktipriya Shridhar
The workqueues "ioc->reset_work_q" and "ioc->fw_event_q" queue a single work item &ioc->fault_reset_work and &fw_event->work, respectively and hence don't require ordering. Hence, they have been converted to use alloc_workqueue(). The WQ_MEM_RECLAIM flag has been set to ensure forward progress under memory pressure since the workqueue belongs to a storage driver which is being used on a memory reclaim path. Since there are fixed number of work items, explicit concurrency limit is unnecessary here.

2016-09-02scsi: mptfc: Remove deprecated create_singlethread_workqueueBhaktipriya Shridhar
The workqueue "fc_rescan_work_q" queues multiple work items viz &ioc->fc_rescan_work, &ioc->fc_lsc_work, &ioc->fc_setup_reset_work, which require strict execution ordering. Hence, an ordered dedicated workqueue has been used. WQ_MEM_RECLAIM has been set since the workqueue is belongs to a storage driver which is being used on a memory reclaim path and hence, requires forward progress under memory pressure.

2016-09-02scsi: bfa: Do not dereference port before it is null checkedColin Ian King
Port is deferenced before it is null sanity checked, hence we potentially have a null pointer dereference bug. Instead, initialise trl_enabled from port->fcs->bfa after we are sure port is not null.
