2022-07-19scsi: qla2xxx: Zero undefined mailbox IN registersBikash Hazarika1-0/+2
While requesting a new mailbox command, driver does not write any data to unused registers. Initialize the unused register value to zero while requesting a new mailbox command to prevent stale entry access by firmware.

2022-07-14scsi: smartpqi: Add ctrl ready timeout module parameterKevin Barnett3-1/+33
Allow user to override the default driver timeout for controller ready. There are some rare configurations which require the driver to wait longer than the normal 3 minutes for the controller to complete its bootup sequence and be ready to accept commands from the driver. The module parameter is: ctrl_ready_timeout= { 0 | 30-1800 } and specifies the timeout in seconds for the driver to wait for controller ready. The valid range is 0 or 30-1800. The default value is 0, which causes the driver to use a timeout of 180 seconds (3 minutes).

2022-07-14scsi: smartpqi: Add module param to disable managed intsMike McGowen2-2/+13
Allow SMP affinity to be changeable by disabling managed interrupts. On distributions where the driver is enabled for multi-queue support the driver utilizes kernel managed interrupts, which automatically distributes interrupts to all available CPUs and assigns SMP affinity. On most distributions, the affinity can not be changed by the user. This change will allow managed interrupts to be disabled by the user via a module parameter while still allowing multi-queue support to function properly. Use the module parameter disable_managed_interrupts=1 Link: https://lore.kernel.org/r/165730606638.177165.12846020942931640329.stgit@brunhilda Reviewed-by: Scott Benesh <scott.benesh@microchip.com> Reviewed-by: Scott Teel <scott.teel@microchip.com> Reviewed-by: Kevin Barnett <kevin.barnett@microchip.com> Signed-off-by: Mike McGowen <Mike.McGowen@microchip.com> Signed-off-by: Don Brace <don.brace@microchip.com> Signed-off-by: Martin K.

A race condition in the driver could cause it to access a stale RAID map when a logical volume is reconfigured.

2022-07-14scsi: smartpqi: Fix DMA direction for RAID requestsMahesh Rajashekhara1-2/+2
Correct a SOP READ and WRITE DMA flags for some requests. This update corrects DMA direction issues with SCSI commands removed from the controller's internal lookup table. Currently, SCSI READ BLOCK LIMITS (0x5) was removed from the controller lookup table and exposed a DMA direction flag issue. SCSI READ BLOCK LIMITS was recently removed from our controller lookup table so the controller uses the respective IU flag field to set the DMA data direction. Since the DMA direction is incorrect the FW never completes the request causing a hang. Some SCSI commands which use SCSI READ BLOCK LIMITS * sg_map * mt -f /dev/stX status After updating controller firmware, users may notice their tape units failing. This patch resolves the issue. Also, the AIO path DMA direction is correct. The DMA direction flag is a day-one bug with no reported BZ.

2022-07-14scsi: smartpqi: Fix PCI control linkdown system hangSagar Biradar3-5/+52
Fail all outstanding requests after a PCI linkdown. Block access to device SCSI attributes during the following conditions: "Cable pull" is called PQI_CTRL_SURPRISE_REMOVAL. "PCIe Link Down" is called PQI_CTRL_GRACEFUL_REMOVAL. Block access to device SCSI attributes during and in rare instances when the controller goes offline. Either outstanding requests or the access of SCSI attributes post linkdown can lead to a hang. Post linkdown, driver does not fail the outstanding requests leading to long wait time before all the IOs eventually fail. Also access of the SCSI attributes by host applications can lead to a system hang.

2022-07-08scsi: ufs: Skip last hci reset to get valid register valuesJunwoo Lee1-1/+1
Once the host link startup fails 3 times, all host registers are reset to default values except in ufshcd_hba_enable(). The ufs host controller is disabled and enabled in ufshcd_hba_enable(). Consequently we need to skip last hci reset to get valid host register values. e.g. [ 1.898026] [2: kworker/u16:2: 211] ufs: link startup failed 1 [ 1.898133] [2: kworker/u16:2: 211] host_regs: 00000000: 1383ff1f 00000000 00000300 00000000 [ 1.898141] [2: kworker/u16:2: 211] host_regs: 00000010: 00000106 000001ce 00000000 00000000 [ 1.898148] [2: kworker/u16:2: 211] host_regs: 00000020: 00000000 00000470 00000000 00000000 [ 1.898155] [2: kworker/u16:2: 211] host_regs: 00000030: 00000008 00000003 00000000 00000000 [ 1.898163] [2: kworker/u16:2: 211] host_regs: 00000040: 00000000 00000000 00000000 00000000 [ 1.898171] [2: kworker/u16:2: 211] host_regs: 00000050: 00000000 00000000 00000000 00000000 [ 1.898177] [2: kworker/u16:2: 211] host_regs: 00000060: 00000000 00000000 00000000 00000000 [ 1.898186] [2: kworker/u16:2: 211] host_regs: 00000070: 00000000 00000000 00000000 00000000 [ 1.898194] [2: kworker/u16:2: 211] host_regs: 00000080: 00000000 00000000 00000000 00000000 [ 1.898201] [2: kworker/u16:2: 211] host_regs: 00000090: 00000000 00000000 00000000 00000000 Link: https://lore.kernel.org/r/20220705083538.15143-1-sh043.lee@samsung.com Reviewed-by: Avri Altman <avri.altman@wdc.com> Signed-off-by: Junwoo Lee <junwoo80.lee@samsung.com> Signed-off-by: Seunghui Lee <sh043.lee@samsung.com> Signed-off-by: Martin K.

2022-07-08scsi: lpfc: Revert RSCN_MEMENTO workaround for misbehaved configurationJames Smart3-9/+3
The RSCN_MEMENTO logic was to workaround a target that does not register both FCP and NVMe FC4 types at the same time. This caused the configuration to not produce a second RSCN for the NVMe FC4 type registration in a timely manner. The intention of the RSCN_MEMENTO flag was to always signal to try NVMe PRLI. However, there are other FCP-only target arrays in correctly behaved configurations that reject the NVMe PRLI followed by a LOGO leading to never rediscovering the target after an issue_lip (as LOGO causes a repeat of PLOGI/PRLIs). Revert the RSCN_MEMENTO patch as it is causing correctly behaved configs to fail while it exists only to succeed on a misbehaved config.

2022-07-08scsi: lpfc: Fix lost NVMe paths during LIF bounce stress testJames Smart1-7/+8
During a target link bounce test, the driver sees a mismatch between the NPortId and the WWPN on the node structures (ndlps) involved. When this occurs, the driver "swaps" the ndlp and new_ndlp node parameters to restore WWPN/DID uniqueness in the fc_nodes list per vport. However, the driver neglected to swap the nlp_fc4_type in the ndlp passed to lpfc_plogi_confirm_nport causing a failure to recover the NVMe PLOGI/PRLI and ultimately the NVMe paths. Correct confirm_nport to preserve the fc4 types from the new-ndlp when the data is moved over ot the ndlp structure.
