2022-06-28scsi: hisi_sas: Limit max hw sectors for v3 HWJohn Garry1-0/+7
If the controller is behind an IOMMU then the IOMMU IOVA caching range can affect performance, as discussed in [0]. Limit the max HW sectors to not exceed this limit. We need to hardcode the value until a proper DMA mapping API is available.

2022-06-17scsi: ibmvfc: Store vhost pointer during subcrq allocationTyrel Datwyler2-2/+3
Currently the back pointer from a queue to the vhost adapter isn't set until after subcrq interrupt registration. The value is available when a queue is first allocated and can/should be also set for primary and async queues as well as subcrqs. This fixes a crash observed during kexec/kdump on Power 9 with legacy XICS interrupt controller where a pending subcrq interrupt from the previous kernel can be replayed immediately upon IRQ registration resulting in dereference of a garbage backpointer in ibmvfc_interrupt_scsi(). Kernel attempted to read user page (58) - exploit attempt?

2022-06-17scsi: ibmvfc: Allocate/free queue resource only during probe/removeTyrel Datwyler1-17/+62
Currently, the sub-queues and event pool resources are allocated/freed for every CRQ connection event such as reset and LPM. This exposes the driver to a couple issues. First the inefficiency of freeing and reallocating memory that can simply be resued after being sanitized. Further, a system under memory pressue runs the risk of allocation failures that could result in a crippled driver. Finally, there is a race window where command submission/compeletion can try to pull/return elements from/to an event pool that is being deleted or already has been deleted due to the lack of host state around freeing/allocating resources.

2022-06-17scsi: storvsc: Correct reporting of Hyper-V I/O size limitsSaurabh Sengar1-5/+22
Current code is based on the idea that the max number of SGL entries also determines the max size of an I/O request. While this idea was true in older versions of the storvsc driver when SGL entry length was limited to 4 Kbytes, commit 3d9c3dcc58e9 ("scsi: storvsc: Enable scatterlist entry lengths > 4Kbytes") removed that limitation. It's now theoretically possible for the block layer to send requests that exceed the maximum size supported by Hyper-V. This problem doesn't currently happen in practice because the block layer defaults to a 512 Kbyte maximum, while Hyper-V in Azure supports 2 Mbyte I/O sizes. But some future configuration of Hyper-V could have a smaller max I/O size, and the block layer could exceed that max. Fix this by correctly setting max_sectors as well as sg_tablesize to reflect the maximum I/O size that Hyper-V reports. While allowing I/O sizes larger than the block layer default of 512 Kbytes doesn’t provide any noticeable performance benefit in the tests we ran, it's still appropriate to report the correct underlying Hyper-V capabilities to the Linux block layer. Also tweak the virt_boundary_mask to reflect that the required alignment derives from Hyper-V communication using a 4 Kbyte page size, and not on the guest page size, which might be bigger (eg. ARM64).

2022-06-14scsi: iscsi: Exclude zero from the endpoint ID rangeSergey Gorenko1-1/+6

The commit referenced in the fixes line changed the endpoint ID range, and zero is always assigned to the first endpoint ID. So, the first attempt to create a new iSER connection always fails.

When a write command to a sequential write required or sequential write preferred zone result in the zone write pointer reaching the end of the zone, the zone condition must be set to full AND the number of implicitly or explicitly open zones updated to have a correct accounting for zone resources. However, the function zbc_inc_wp() only sets the zone condition to full without updating the open zone counters, resulting in a zone state machine breakage. Introduce the helper function zbc_set_zone_full() and use it in zbc_inc_wp() to correctly transition zones to the full condition.

Nevertheless, gcc complains because the whole Mpi2SasIOUnitPage1_t struct is 32 bytes in size and thus doesn't fit into those 20 bytes. This patch simply allocates all 32 bytes (instead of 20) and thus avoids the warning. There is no functional change introduced by this patch. While touching the code I cleaned up to calculation of max_wideport_qd, max_narrowport_qd and max_sata_qd to make it easier readable.

After issuing a LIP, a specific target vendor does not ACC the FLOGI that lpfc sends. However, it does send its own FLOGI that lpfc ACCs. The target then establishes the port IDs by sending a PLOGI. lpfc PLOGI_ACCs and starts the RPI registration for DID 0x000001. The target then sends a LOGO to the fabric DID. lpfc is currently treating the LOGO from the fabric DID as a link down and cleans up all the ndlps. The ndlp for DID 0x000001 is put back into NPR and discovery stops, leaving the port in stuck in bypassed mode. Change lpfc behavior such that if a LOGO is received for the fabric DID in PT2PT topology skip the lpfc_linkdown_port() routine and just move the fabric DID back to NPR.

Fixing the interpretation of the length of the B9h VPD page (Concurrent Positioning Ranges).

2022-06-02scsi: sd_zbc: Prevent zone information memory leakDamien Le Moal3-16/+16
Make sure to always free a scsi disk zone information, even for regular disks. This ensures that there is no memory leak, even in the case of a zoned disk changing type to a regular disk (e.g. with a reformat using the FORMAT WITH PRESET command or other vendor proprietary command). To do this, rename sd_zbc_clear_zone_info() to sd_zbc_free_zone_info() and remove sd_zbc_release_disk(). A call to sd_zbc_free_zone_info() is added to sd_zbc_read_zones() for drives for which sd_is_zoned() returns false. Furthermore, sd_zbc_free_zone_info() code make s sure that the sdkp rev_mutex is never used while not being initialized by gating the cleanup code with a a check on the zone_wp_update_buf field as it is never NULL when rev_mutex has been initialized.

2022-06-02scsi: sd: Fix potential NULL pointer dereferenceDamien Le Moal1-1/+0
If sd_probe() sees an early error before sdkp->device is initialized, sd_zbc_release_disk() is called. This causes a NULL pointer dereference when sd_is_zoned() is called inside that function. Avoid this by removing the call to sd_zbc_release_disk() in sd_probe() error path. This change is safe and does not result in zone information memory leakage because the zone information for a zoned disk is allocated only when sd_revalidate_disk() is called, at which point sdkp->disk_dev is fully set, resulting in sd_disk_release() being called when needed to cleanup a disk zone information using sd_zbc_release_disk().

The latest storvsc code has already removed the support for windows 7 and earlier. There is still some code logic remaining which is there to support pre Windows 8 OS. This patch removes these stale logic. This patch majorly does three things : 1. Removes vmscsi_size_delta and its logic, as the vmscsi_request struct is same for all the OS post windows 8 there is no need of delta. 2. Simplify sense_buffer_size logic, as there is single buffer size for all the post windows 8 OS. 3. Embed the vmscsi_win8_extension structure inside the vmscsi_request, as there is no separate handling required for different OS.

2022-05-24scsi: myrb: Fix up null pointer access on myrb_cleanup()Hannes Reinecke1-3/+8
When myrb_probe() fails the callback might not be set, so we need to validate the 'disable_intr' callback in myrb_cleanup() to not cause a null pointer exception. And while at it do not call myrb_cleanup() if we cannot enable the PCI device at all.

2022-05-20scsi: ufs: Split the drivers/scsi/ufs directoryBart Van Assche46-27042/+0
Split the drivers/scsi/ufs directory into 'core' and 'host' directories under the drivers/ufs/ directory. Move shared header files into the include/ufs/ directory. This separation makes it clear which header files UFS drivers are allowed to include (include/ufs/*.h) and which header files UFS drivers are not allowed to include (drivers/ufs/core/*.h). Update the MAINTAINERS file. Add myself as a UFS reviewer.
