Stop the OS from re-discovering multiple LUNs for tape drive and medium changer. Duplicate device nodes for Ultrium tape drive and medium changer are being created. The Ultrium tape drive is a multi-LUN SCSI target. It presents a LUN for the tape drive and a 2nd LUN for the medium changer. Our controller FW lists both LUNs in the RPL results. As a result, the smartpqi driver exposes both devices to the OS. Then the OS does its normal device discovery via the SCSI REPORT LUNS command, which causes it to re-discover both devices a 2nd time, which results in the duplicate device nodes.

Prevent kernel crash by failing outstanding I/O request when the OS takes device offline. When posted I/Os to the controller's inbound queue are not picked by the controller, the driver will halt the controller and take the controller offline. When the driver takes the controller offline, the driver will fail all the outstanding requests which can sometimes lead to an OS crash.

Send a TEST UNIT READY to HBA disks and do not present them to the OS if 0x02/0x04/0x1b (SANITIZE IN PROGRESS) is returned. During boot-up, some OSes appear to hang when there are one or more disks undergoing a sanitize operation. According to SCSI SBC4 specification section 4.11.2 "Commands allowed during SANITIZE", some SCSI commands are permitted, but read/write operations are not. When the OS attempts to read the disk partition table a CHECK CONDITION ASC 0x04 ASCQ 0x1b is returned which causes the OS to retry the read until SANITIZE has completed. This can take hours. According to document HPE Smart Storage Administrator User Guide, during the sanitize erase operation, the drive is unusable. I.e. the expected behavior for SANITIZE is the that disk remains offline even after SANITIZE has completed. The customer is expected to re-enable the disk using the management utility.

Enhance check for commands queued to the controller. Add new function pqi_nonempty_inbound_queue_count() that will wait for all I/O queued for submission to controller across all queue groups to drain. Add helper functions to obtain queue command counts for each queue group. These queues should drain quickly as they are already staged to be submitted down to the controller's IB queue. Enhance check for outstanding command completion. Update the count of outstanding commands while waiting. This value was not re-obtained and was potentially causing infinite wait for all completions.

Correct kdump hangs when controller is locked up. There are occasions when a controller reboot (controller soft reset) is issued when a controller firmware crash dump is in progress. This leads to incomplete controller firmware crash dump: - When the controller crash dump is in progress, and a kdump is initiated, the driver issues inbound doorbell reset to bring back the controller in SIS mode. - If the controller is in locked up state, the inbound doorbell reset does not work causing controller initialization failures. This results in the driver hanging waiting for SIS mode. To avoid an incomplete controller crash dump, add in a controller crash dump handshake: - Controller will indicate start and end of the controller crash dump by setting some register bits. - Driver will look these bits when a kdump is initiated. If a controller crash dump is in progress, the driver will wait for the controller crash dump to complete before issuing the controller soft reset then complete driver initialization.

IRQ polling thread calls ISR after enable_irq() to handle any missed I/O completion. The atomic flag "in_used" was added to have the synchronization between the IRQ polling thread and the interrupt context. There is a bug around it leading to a race condition. Below is the sequence: - IRQ polling thread accesses ISR, fetches the reply descriptor. - Real interrupt arrives and pre-empts polling thread (enable_irq() is already called). - Interrupt context picks the same reply descriptor as fetched by polling thread, processes it, and exits. - Polling thread resumes and processes the descriptor which is already processed by interrupt thread leads to kernel crash. Setting the "in_used" flag before fetching the reply descriptor ensures synchronized access to ISR.

Change the log level of the following message to debug: Unsupported SCSI Opcode 0xXX, sending CHECK_CONDITION. This message is mostly helpful during debugging sessions in order to understand errors on the initiator side. But most of the time it's just useless and makes reading logs much harder. It gets particularly annoying if there are many initiators that come and go or if an initiator runs a program that does not care whether the command is supported and just keeps sending it.

Commit aa53f580 ("scsi: ufs: Minor adjustments to error handling") introduced a ufshcd_clear_ua_wluns() call in ufshcd_err_handling_unprepare(). As explained in detail by Adrian Hunter, this can trigger a deadlock. Avoid that deadlock by removing the code that clears the unit attention. This is safe because the only software that relies on clearing unit attentions is the Android Trusty software and because support for handling unit attentions has been added in the Trusty software. See also https://lore.kernel.org/linux-scsi/20210930124224.114031-2-adrian.hunter@intel.com/ Note that "scsi: ufs: Retry START_STOP on UNIT_ATTENTION" is a prerequisite for this commit.

Commit 57d104c1 ("ufs: add UFS power management support") made the UFS driver submit a REQUEST SENSE command before submitting a power management command to a WLUN to clear the POWER ON unit attention. Instead of submitting a REQUEST SENSE command before submitting a power management command, retry the power management command until it succeeds. This is the preparation to get rid of all UNIT ATTENTION code which should be handled by users.

The MODE SELECT(6) command allows handling mode page buffers that are up to 255 bytes, including the 4 byte header needed in front of the page buffer. For requests larger than this limit, automatically use the MODE SELECT(10) command. In both cases, since scsi_mode_select() adds the mode select page header, checks on the buffer length value must include this header size to avoid overflows of the command CDB allocation length field. While at it, use put_unaligned_be16() for setting the header block descriptor length and CDB allocation length when using MODE SELECT(10).

Several problems exist with scsi_mode_sense() buffer length handling: 1) The allocation length field of the MODE SENSE(10) command is 16-bits, occupying bytes 7 and 8 of the CDB. With this command, access to mode pages larger than 255 bytes is thus possible. However, the CDB allocation length field is set by assigning len to byte 8 only, thus truncating buffer length larger than 255. 2) If scsi_mode_sense() is called with len smaller than 8 with sdev->use_10_for_ms set, or smaller than 4 otherwise, the buffer length is increased to 8 and 4 respectively, and the buffer is zero filled with these increased values, thus corrupting the memory following the buffer. Fix these 2 problems by using put_unaligned_be16() to set the allocation length field of MODE SENSE(10) CDB and by returning an error when len is too small. Furthermore, if len is larger than 255B, always try MODE SENSE(10) first, even if the device driver did not set sdev->use_10_for_ms. In case of invalid opcode error for MODE SENSE(10), access to mode pages larger than 255 bytes are not retried using MODE SENSE(6). To avoid buffer length overflows for the MODE_SENSE(10) case, check that len is smaller than 65535 bytes. While at it, also fix the folowing: * Use get_unaligned_be16() to retrieve the mode data length and block descriptor length fields of the mode sense reply header instead of using an open coded calculation. * Fix the kdoc dbd argument explanation: the DBD bit stands for Disable Block Descriptor, which is the opposite of what the dbd argument description was.

It has been compile tested. @@ @@ - PCI_DMA_BIDIRECTIONAL + DMA_BIDIRECTIONAL @@ @@ - PCI_DMA_TODEVICE + DMA_TO_DEVICE @@ @@ - PCI_DMA_FROMDEVICE + DMA_FROM_DEVICE @@ @@ - PCI_DMA_NONE + DMA_NONE @@ expression e1, e2, e3; @@ - pci_alloc_consistent(e1, e2, e3) + dma_alloc_coherent(&e1->dev, e2, e3, GFP_) @@ expression e1, e2, e3; @@ - pci_zalloc_consistent(e1, e2, e3) + dma_alloc_coherent(&e1->dev, e2, e3, GFP_) @@ expression e1, e2, e3, e4; @@ - pci_free_consistent(e1, e2, e3, e4) + dma_free_coherent(&e1->dev, e2, e3, e4) @@ expression e1, e2, e3, e4; @@ - pci_map_single(e1, e2, e3, e4) + dma_map_single(&e1->dev, e2, e3, e4) @@ expression e1, e2, e3, e4; @@ - pci_unmap_single(e1, e2, e3, e4) + dma_unmap_single(&e1->dev, e2, e3, e4) @@ expression e1, e2, e3, e4, e5; @@ - pci_map_page(e1, e2, e3, e4, e5) + dma_map_page(&e1->dev, e2, e3, e4, e5) @@ expression e1, e2, e3, e4; @@ - pci_unmap_page(e1, e2, e3, e4) + dma_unmap_page(&e1->dev, e2, e3, e4) @@ expression e1, e2, e3, e4; @@ - pci_map_sg(e1, e2, e3, e4) + dma_map_sg(&e1->dev, e2, e3, e4) @@ expression e1, e2, e3, e4; @@ - pci_unmap_sg(e1, e2, e3, e4) + dma_unmap_sg(&e1->dev, e2, e3, e4) @@ expression e1, e2, e3, e4; @@ - pci_dma_sync_single_for_cpu(e1, e2, e3, e4) + dma_sync_single_for_cpu(&e1->dev, e2, e3, e4) @@ expression e1, e2, e3, e4; @@ - pci_dma_sync_single_for_device(e1, e2, e3, e4) + dma_sync_single_for_device(&e1->dev, e2, e3, e4) @@ expression e1, e2, e3, e4; @@ - pci_dma_sync_sg_for_cpu(e1, e2, e3, e4) + dma_sync_sg_for_cpu(&e1->dev, e2, e3, e4) @@ expression e1, e2, e3, e4; @@ - pci_dma_sync_sg_for_device(e1, e2, e3, e4) + dma_sync_sg_for_device(&e1->dev, e2, e3, e4) @@ expression e1, e2; @@ - pci_dma_mapping_error(e1, e2) + dma_mapping_error(&e1->dev, e2) @@ expression e1, e2; @@ - pci_set_dma_mask(e1, e2) + dma_set_mask(&e1->dev, e2) @@ expression e1, e2; @@ - pci_set_consistent_dma_mask(e1, e2) + dma_set_coherent_mask(&e1->dev, e2) Link: https://lore.kernel.org/r/3899b1ed4abac581c30845d82f33ec6df8b38976.1629633207.git.christophe.jaillet@wanadoo.frSigned-off-by:

Qualcomm controller needs to be in hibern8 before scaling clocks. This change puts the controller in hibern8 state before scaling and brings it out after scaling of clocks. Link: https://lore.kernel.org/r/212b7aaf6d834c4a8c682fdac4a59b84013ed573.1632818942.git.nguyenb@codeaurora.orgReviewed-by:
