For session recovery, driver relies on the dpc thread to initiate certain operations. The dpc thread runs exclusively without the Mailbox interface being occupied.

User experienced device lost. The log shows Get port data base command was queued up, failed, and requeued again. Every time it is requeued, it set the FCF_ASYNC_ACTIVE. This prevents any recovery code from occurring because driver thinks a recovery is in progress for this session. In essence, this session is hung. The reason it gets into this place is the session deletion got in front of this call due to link perturbation. Break the requeue cycle and exit.

User experienced some of the LUN failed to get rediscovered after long cable pull test. The issue is triggered by a race condition between driver setting session online state vs starting the LUN scan process at the same time. Current code set the online state after notifying the session is available. In this case, trigger to start the LUN scan process happened before driver could set the session in online state. LUN scan ends up with failure due to the session online check was failing. Set the online state before reporting of the availability of the session.

We need to support parsing the HID device in both the Vivaldi and the Hammer drivers so that we can properly expose the function row physmap to userspace when a hammer device uses a vivaldi keyboard layout for the function row keys. Extract the feature mapping logic from the vivaldi driver into an hid specific vivaldi library so we can use it from both HID drivers. To allow more code sharing we mandate that vivaldi data must be placed at the very beginning of the driver data attached to the HID device instance.

2022-03-14scsi: target: Add iscsi/cpus_allowed_list in configfsMingzhe Zou
The RX/TX threads for iSCSI connection can be scheduled to any online CPUs, and will not be rescheduled. When binding other heavy load threads along with iSCSI connection RX/TX thread to the same CPU, the iSCSI performance will be worse. Add iscsi/cpus_allowed_list in configfs. The available CPU set of iSCSI connection RX/TX threads is allowed_cpus & online_cpus. If it is modified, all RX/TX threads will be rescheduled.

2022-03-14scsi: hisi_sas: Use libsas internal abort supportJohn Garry
Use the common libsas internal abort functionality. In addition, this driver has special handling for internal abort timeouts - specifically whether to reset the controller in that instance, so extend the API for that. Timeout is now increased to 20 * Hz from 6 * Hz. We also retry for failure now, but this should not make a difference.

2022-03-14scsi: libsas: Add sas_execute_internal_abort_single()John Garry
The internal abort feature is common to hisi_sas and pm8001 HBAs, and the driver support is similar also, so add a common handler. Two modes of operation will be supported: - single: Abort a single tagged command - device: Abort all commands associated with a specific domain device A new protocol is added, SAS_PROTOCOL_INTERNAL_ABORT, so the common queue command API may be re-used. Only add "single" support as a first step.

2022-03-14scsi: lpfc: Remove failing soft_wwn supportJames Smart
The soft_wwpn/soft_wwn functionality, which allows the driver to modify service parameters in an attempt to override the adapter-assigned WWN, was originally attempted to be removed roughly 6 yrs ago as new fabric features were being introduced that clashed with the implementation. In the end, the feature was left in with the user being responsible if things went south. We've reached a point where soft_wwn is no longer functional and is failing in almost all production use cases. Use of Fabric features such as Fabric Assigned WWPN and Automatic DPORT is now prevalent and the features require coordination between the adapter and driver that can't be solved by the simplistic update of the service parameters. As it is no longer functional, the feature is to be removed. There are still ways to override the adapter-assigned WWN but they require the admin to invoke bios/efi level menus.
