* scsi: mpi3mr: Add support for NVMe passthroughSumit Saxena2022-05-022-3/+370
| | | | | | | | | | | | | | | Add support for management applications to send an MPI3 Encapsulated NVMe passthru command to the NVMe devices attached to an Avenger controller. Since the NVMe drives are exposed as SCSI devices by the controller, the standard NVMe applications cannot be used to interact with the drives and the command sets supported are also limited by the controller firmware. Special handling is required for MPI3 Encapsulated NVMe passthru commands for PRP/SGL setup in the commands.

* scsi: sd: Reorganize DIF/DIX code to avoid calling revalidate twiceMartin K. Petersen2022-05-022-34/+36
| | | | | | | | | | | | | | | | | | | | During device discovery we ended up calling revalidate twice and thus requested the same parameters multiple times. This was originally necessary due to the request_queue and gendisk needing to be instantiated to configure the block integrity profile. Since this dependency no longer exists, reorganize the integrity probing code so it can be run once at the end of discovery and drop the superfluous revalidate call. Postponing the registration step involves splitting sd_read_protection() into two functions, one to read the device protection type and one to configure the mode of operation. As part of this cleanup, make the printing code a bit less verbose.

* scsi: sd: Optimal I/O size should be a multiple of reported granularityMartin K. Petersen2022-05-022-4/+42
| | | | | | | | | | | | | | | | | | | | | | | Commit a83da8a4509d ("scsi: sd: Optimal I/O size should be a multiple of physical block size") validated the reported optimal I/O size against the physical block size to overcome problems with devices reporting nonsensical transfer sizes. However, some devices claim conformity to older SCSI versions that predate the physical block size being reported. Other devices do not report a physical block size at all. We need to be able to validate the optimal I/O size on those devices as well. Many devices report an OPTIMAL TRANSFER LENGTH GRANULARITY in the same VPD page as the OPTIMAL TRANSFER LENGTH. Use this value to validate the optimal I/O size. Also check that the reported granularity is a multiple of the physical block size, if supported.

| | | | | | | | | | | | | | | | | Low-level device drivers have had the ability to limit the size of an INQUIRY for many years. This made sense for a wide variety of legacy devices. However, we are unnecessarily truncating the INQUIRY response for many modern devices. This prevents us from consulting fields beyond the first 36 bytes. If a device reports that it supports a larger INQUIRY response, and the device also reports that it implements SPC-4 or newer, allow the larger INQUIRY to proceed.

* scsi: core: Query VPD size before getting full pageMartin K. Petersen2022-05-021-31/+58
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We currently default to 255 bytes when fetching VPD pages during discovery. However, we have had a few devices that are known to wedge if the requested buffer exceeds a certain size. See commit af73623f5f10 ("[SCSI] sd: Reduce buffer size for vpd request") which works around one example of this problem in the SCSI disk driver. With commit d188b0675b21 ("scsi: core: Add sysfs attributes for VPD pages 0h and 89h") we now risk triggering the same issue in the generic midlayer code. The problem with the ATA VPD page in particular is that the SCSI portion of the page is trailed by 512 bytes of verbatim ATA Identify Device information. However, not all controllers actually provide the additional 512 bytes and will lock up if one asks for more than the 64 bytes containing the SCSI protocol fields. Instead of picking a new, somewhat arbitrary, number of bytes for the VPD buffer size, start fetching the 4-byte header for each page. The header contains the size of the page as far as the device is concerned. We can use the reported size to specify the correct allocation length when subsequently fetching the full page. The header validation is done by a new helper function scsi_get_vpd_size() and both scsi_get_vpd_page() and scsi_get_vpd_buf() now rely on this to query the page size. In addition, scsi_get_vpd_page() is simplified to mirror the logic in scsi_get_vpd_page(). This involves removing the Supported VPD Pages lookup prior to attempting to query a page. There does not appear any evidence, even in the oldest SCSI specs, that this step is required. We already rely on scsi_get_vpd_page() throughout the stack and this function never consulted the Supported VPD Pages. Since this has not caused any problems it should be safe to remove the precondition from scsi_get_vpd_page(). Instrumented runs also revealed that the Supported VPD Pages lookup had little effect since the device page index often was larger than the supplied buffer size. As a result, inquiries frequently bypassed the index check and went through the "If we ran off the end of the buffer, give us the benefit of the doubt" code path which assumed the page was present despite not being listed. The revised code takes both the page size reported by the device as well as the size of the buffer provided by the scsi_get_vpd_page() caller into account.

| | | | | | | | | | | | | | | | | | | For SCSI hosts which enable host_tagset the NUMA node returned from blk_mq_hw_queue_to_node() is NUMA_NO_NODE always. Then, since in scsi_mq_setup_tags() the default we choose for the tag_set NUMA node is NUMA_NO_NODE, we always evaluate the NUMA node as NUMA_NO_NODE in functions like blk_mq_alloc_rq_map(). The reason we get NUMA_NO_NODE from blk_mq_hw_queue_to_node() is that the hctx_idx passed is BLK_MQ_NO_HCTX_IDX - so we can't match against a (HW) queue mapping index. Improve this by defaulting the tag_set NUMA node to the same NUMA node of the SCSI host DMA dev.

* scsi: sd: sd_zbc: Hide gap zonesDamien Le Moal2022-04-262-13/+97
| | | | | | | | | | | | | | | | | | | ZBC-2 allows host-managed disks to report gap zones. This allow zoned disks to report an offset between data zone starts that is a power of two even if the number of logical blocks with data per zone is not a power of two. Another new feature in ZBC-2 is support for constant zone starting LBA offsets. For zoned disks that report a constant zone starting LBA offset, hide the gap zones from the block layer. Report the offset between data zone starts as zone size and report the number of logical blocks with data per zone as the zone capacity.
