2021-08-24scsi: ufs: Fix ufshcd_request_sense_async() for Samsung KLUFG8RHDA-B2D1Adrian Hunter
Samsung KLUFG8RHDA-B2D1 does not clear the unit attention condition if the length is zero. So go back to requesting all the sense data, as it was before patch "scsi: ufs: Request sense data asynchronously". That is simpler than creating and maintaining a quirk for affected devices.

2021-08-24scsi: lpfc: Add support for the CM frameworkJames Smart
Complete the enablement of the cm framework feature in the adapter. Perform the following: - Detect the presence of the congestion management framework feature. When the cm framework is present: - Issue the SET_FEATURE command to enable the feature. - Register the cm statistics buffer with the adapter. - Read the cm enablement buffer to determine the cm framework state for cm management. When cm management is enabled: - Monitor all FPIN and congestion signalling events, incrementing counters. - Regularly sync with the adapter to communicate congestion events and to receive an rx request limit. - Monitor requests for rx data and ensure that no more than the adapter prescribed limit is issued on the link. If the limit is exceeded, SCSI and/or NVMe traffic is temporarily suspended. - Maintain the minute, hourly, daily statistics buffer. - Monitor for congestion enablement change events, causing a reread of the enablement buffer and acting on any change in enablement. And: - Add teardown logic, including buffer deregistration, on adapter detachment or reset.

As part of the cmf framework, the firmware maintains a table with congestion related state information, specifically whether enabled and if enabled, whether monitoring or actively managing congestion. Add definition of the table and add support to read the table from the adapter and determine if it is enabled. In support of this, the READ_OBJECT mailbox command definition is added to the driver.

The cmf framework requires the driver to maintain a cm statistics table, accessible inband, of congestion related statistics that are reported per minute, rolled up to per hour, and rolled up again per day. Several days worth may be maintained. The table is registered with the adapter when the MIB feature is enabled. Add definition of the table and add support to register the table with the adapter. Includes definition and initialization of event counters that are later added to the statistics table.

2021-08-24scsi: lpfc: Add MIB feature enablement supportJames Smart
MIB support is currently limited to detecting support in the adapter and ensuring FDMI support is enabled if present. For the new framework MIB support also requires active enablement of support via the SET_FEATURES command with the firmware. Rework the MIB detection and enablement for the following: - Move detection away from the get_sli4_parameters routine, and into the hba_setup path. get_sli4_parameters is only called once at attachment while hba_setup is called as part of any SLI port reset path. This ensures detection after firmware download. - Update SET_FEATURES mbx command for the MIB enablement feature and add support for the feature. - Create the cmf_setup routine to encapsulate the detection of MIB support and perform the enablement of the MIB support feature.

2021-08-23scsi: qla2xxx: Fix hang during NVMe session tear downArun Easi
The following hung task call trace was seen: [ 1230.183294] INFO: task qla2xxx_wq:523 blocked for more than 120 seconds.

Abort threads were getting out without processing due to the "deleted" flag check. The delete thread, meanwhile, could not proceed with a logout (that would have cleared out pending requests) as the logout IOCB work was not progressing. It appears like the hung qlt_free_session_done() thread is causing the ha->wq works on hold. The qlt_free_session_done() was hung waiting for nvme_fc_unregister_remoteport() + localport_delete cb to be complete, which would only happen when all I/Os are released. Fix this by allowing abort to progress until device delete is completely done. This should make the qlt_free_session_done() proceed without hang and thus clear up the deadlock.

edif_enabled is prematurely turned on if hardware is capable of handling the feature. However, firmware also needs to support EDIF before enabling this bit.

So return immediately from scsi_scan_host() during probe() and avoid any udev stalls during booting.

2021-08-17scsi: target: Allows backend drivers to fail with specific sense codesSergey Samoylenko
Currently, backend drivers can fail I/O with SAM_STAT_CHECK_CONDITION which gets us TCM_LOGICAL_UNIT_COMMUNICATION_FAILURE. Add a new helper that allows backend drivers to fail with specific sense codes. This is based on a patch from Mike Christie <michael.christie@oracle.com>.

2021-08-17scsi: smartpqi: Replace one-element array with flexible-array memberGustavo A. R. Silva
There is a regular need in the kernel to provide a way to declare having a dynamically sized set of trailing elements in a structure. Kernel code should always use "flexible array members"[1] for these cases. The older style of one-element or zero-length arrays should no longer be used[2]. Refactor the code a bit according to the use of a flexible-array member in struct pqi_event_config instead of a one-element array, and use the struct_size() helper. This helps with the ongoing efforts to globally enable -Warray-bounds and get us closer to being able to tighten the FORTIFY_SOURCE routines on memcpy(). This issue was found with the help of Coccinelle and audited and fixed, manually.
