| |/ |/| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | During system shutdown or reboot, mpt3sas will reset the firmware back to ready state. However, the driver leaves running a watchdog work item intended to keep the firmware in operational state. This causes a second, unneeded reset on shutdown and moves the firmware back to operational instead of in ready state as intended. And if the mpt3sas_fwfault_debug module parameter is set, this extra reset also panics the system. mpt3sas's scsih_shutdown needs to stop the watchdog before resetting the firmware back to ready state.

|/ | | | | | | | | | | | | | | | | | | | | | | | | | | | The driver uses irq_set_affinity_hint() specifically for the high IOPS queue interrupts for two purposes: - To set the affinity_hint which is consumed by the userspace for distributing the interrupts - To apply an affinity that it provides The driver enforces its own affinity to bind the high IOPS queue interrupts to the local NUMA node. However, irq_set_affinity_hint() applying the provided cpumask as an affinity (if not NULL) for the interrupt is an undocumented side effect. To remove this side effect irq_set_affinity_hint() has been marked as deprecated and new interfaces have been introduced. Hence, replace the irq_set_affinity_hint() with the new interface irq_set_affinity_and_hint() where the provided mask needs to be applied as the affinity and affinity_hint pointer needs to be set and replace with irq_update_affinity_hint() where only affinity_hint needs to be updated.

* scsi: mpt3sas: Fix system going into read-only modeSreekanth Reddy2021-11-192-1/+60
| | | | | | | | | | | | | | | | | | | | | While determining the SAS address of a drive, the driver checks whether the handle number is less than the HBA phy count or not. If the handle number is less than the HBA phy count then driver assumes that this handle belongs to HBA and hence it assigns the HBA SAS address. During IOC firmware downgrade operation, if the number of HBA phys is reduced and the OS drive's device handle drops below the phy count while determining the drive's SAS address, the driver ends up using the HBA's SAS address. This leads to a mismatch of drive's SAS address and hence the driver unregisters the OS drive and the system goes into read-only mode. Update the IOC's num_phys to the HBA phy count provided by actual loaded firmware.

* scsi: mpt3sas: Fix kernel panic during drive powercycle testSreekanth Reddy2021-11-191-1/+1
| | | | | | | | | | | | | | | While looping over shost's sdev list it is possible that one of the drives is getting removed and its sas_target object is freed but its sdev object remains intact. Consequently, a kernel panic can occur while the driver is trying to access the sas_address field of sas_target object without also checking the sas_target object for NULL.

* | scsi: mpt3sas: Fix reference tag handling for WRITE_INSERTMartin K. Petersen2021-10-291-3/+6
|/ | | | | | | | | | | | | | | Testing revealed a problem with how the reference tag was handled for a WRITE_INSERT operation. The SCSI_PROT_REF_CHECK flag is not set when the controller is asked to generate the protection information (i.e. not DIX). And as a result the initial reference tag would not be set in the WRITE_INSERT case. Separate handling of the REF_CHECK and REF_INCREMENT flags to align with both the DIX spec and the MPI implementation.
