During driver unload, the remove flag will be set for all scsi_qla_host/NPIV. This allows each NPIV to see the flag instead of reaching for base_vha to search for it. Link: https://lore.kernel.org/r/20190912180918.6436-11-hmadhani@marvell.comSigned-off-by:

Add error handling logic to ELS Passthrough relating to NVME devices. Current code does not parse error code to take proper recovery action, instead it re-logins with the same login parameters that encountered the error. Ex: nport handle collision.

Some storage arrays advertise FCP LUNs and NVMe namespaces behind the same WWN. The driver now offers a user option by way of NVRAM parameter to allow users to choose, on a per port basis, the kind of FC-4 type they would like to prioritize for login.

On excessive bit errors for the FCP channel ingress fibre path, the channel notifies us. Previously, we only emitted a kernel message and a trace record. Since performance can become suboptimal with I/O timeouts due to bit errors, we now stop using an FCP device by default on channel notification so multipath on top can timely failover to other paths. A new module parameter zfcp.ber_stop can be used to get zfcp old behavior. User explanation of new kernel message: * Description: * The FCP channel reported that its bit error threshold has been exceeded. * These errors might result from a problem with the physical components * of the local fibre link into the FCP channel. * The problem might be damage or malfunction of the cable or * cable connection between the FCP channel and * the adjacent fabric switch port or the point-to-point peer. * Find details about the errors in the HBA trace for the FCP device. * The zfcp device driver closed down the FCP device * to limit the performance impact from possible I/O command timeouts. * User action: * Check for problems on the local fibre link, ensure that fibre optics are * clean and functional, and all cables are properly plugged. * After the repair action, you can manually recover the FCP device by * writing "0" into its "failed" sysfs attribute. * If recovery through sysfs is not possible, set the CHPID of the device * offline and back online on the service element.

When a non-passthrough command is terminated with CHECK CONDITION, request sense is executed by hijacking the command descriptor. Since scsi_eh_prep_cmnd() and scsi_eh_restore_cmnd() do not save/restore the original command resid, the value returned on failure of the original command is lost and replaced with the value set by the execution of the request sense command. This value may in many instances be unaligned to the device sector size, causing sd_done() to print a warning message about the incorrect unaligned resid before the command is retried. Fix this problem by saving the original command residual in struct scsi_eh_save using scsi_eh_prep_cmnd() and restoring it in scsi_eh_restore_cmnd(). In addition, to make sure that the request sense command is executed with a correctly initialized command structure, also reset the residual to 0 in scsi_eh_prep_cmnd() after saving the original command value in struct scsi_eh_save.

Commit 88263208 ("scsi: qla2xxx: Complain if sp->done() is not called from the completion path") introduced the WARN_ON_ONCE in qla2x00_status_cont_entry().

Rework from previous work by: Sujit Reddy Thumma <sthumma@codeaurora.org> Until now the scsi mid-layer forbids runtime suspend till userspace enables it. This is mainly to quarantine some disks with broken runtime power management or have high latencies executing suspend resume callbacks. If the userspace doesn't enable the runtime suspend the underlying hardware will be always on even when it is not doing any useful work and thus wasting power. Some low-level drivers for the controllers can efficiently use runtime power management to reduce power consumption and improve battery life. Allow runtime suspend parameters override within the LLD itself instead of waiting for userspace to control the power management.

Added a new status flag named MPT3_DIAG_BUFFER_IS_APP_OWNED and it will set whenever application registers the diag buffer & it will be cleared when application unregisters the buffer. When this flag is enabled, and if application issues diag buffer register command without releasing the buffer, then register command will be failed with -EINVAL status by saying that this buffer is already registered by the application. When user issues a trace buffer register command through sysfs parameter, and if trace buffer is in released stated but not yet unregistered by the application which was owning it, then driver will unregister the buffer by itself and freshly register the 1MB sized trace buffer with the HBA firmware.

The diag buffer which is allocated during driver load time or through sysfs parameter is marked as driver allocated diag buffer. MPT3_DIAG_BUFFER_IS_DRIVER_ALLOCATED bit will be set for this buffer. This buffer won't be de-allocated even when application issues unregister command, driver just clears the registered status bit. Same buffer will be reused while re-registering the same diag buffer type by any application. While re-registering the same diag buffer type application has to register with the same size that the buffer was allocated during driver load time. This buffer size can be read by the application by issuing diag 'query' command. This always makes sure that the memory is available for applications for collecting the firmware logs. Only thing is that this won't allow the application to re-register the diag buffer with different size, but the buffer size which is allocated during driver load time will be enough for most of the cases for collecting the firmware logs.

Application A has registered a diag buffer and looking for particular event to happen to release & read the trace buffer. Meanwhile application B has unregistered the diag buffer and now Application A can't get the required diag buffer. So proper diag buffer ownership is missing. Each application has to maintain its own Unique ID. Now driver has to save the Application's UniqueID for each diag buffer type when diag buffer is registered. And driver has to allow 'release', 'read' & 'unregister' diag commands only if application's UniqueID matches with saved UniqueID for the corresponding diag buffer type. When diag buffer is registered by the driver, then the UniqueID saved by the driver is "BRCM" (i.e. 0x4252434D) for SAS3 and above generations HBA devices. For SAS2 HBAs, driver keeps the legacy UniqueID 0x07075900 for maintaining compatibility with the legacy SAS2 application and this improvement won't be applicable for SAS2 HBA devices. Any application can own the buffer registered by the driver by sending diag register request to driver with same buffer type and size (Application can get the buffer size by sending 'query' command). Then driver changes the ownership of the buffer by saving application's UniqueID for that corresponding buffer type. Also, application can re-register the diag buffer with same size without un-registering it, but diag buffer should be released before re-registering it. By allowing this, driver no need to deallocate and allocate a new buffer for re-register command, same buffer can be re-used.
