scsi: core: Make SCSI_MOD depend on BLOCK for cleaner .config files

2022-09-25T16:46:59Z

SCSI_MOD is a helper config symbol for configuring RAID_ATTRS properly, i.e., RAID_ATTRS needs to be m when SCSI=m. This helper config symbol SCSI_MOD still shows up even in kernel configurations that do not select the block subsystem and where SCSI is not even a configuration option mentioned and selectable. Make this SCSI_MOD depend on BLOCK, so that it only shows up when it is slightly relevant in the kernel configuration.

scsi: dpt_i2o: Remove obsolete driver

2022-06-28T02:56:21Z

The dpt_i2o driver was fixed to stop using virt_to_bus() in 2008, but it still has a stale reference in an error handling code path that could never work. I submitted a patch to fix this reference earlier, but Hannes Reinecke suggested that removing the driver may be just as good here. The i2o driver layer was removed in 2015 with commit 4a72a7af462d ("staging: remove i2o subsystem"), but the even older dpt_i2o scsi driver stayed around. The last non-cleanup patches I could find were from Miquel van Smoorenburg and Mark Salyzyn back in 2008, they might know if there is any chance of the hardware still being used anywhere.

scsi: BusLogic: Remove bus_to_virt()

2022-06-28T02:52:05Z

The BusLogic driver is the last remaining driver that relies on the deprecated bus_to_virt() function, which in turn only works on a few architectures, and is incompatible with both swiotlb and iommu support. Before commit 391e2f25601e ("[SCSI] BusLogic: Port driver to 64-bit."), the driver had a dependency on x86-32, presumably because of this problem. However, the change introduced another bug that made it still impossible to use the driver on any 64-bit machine. This was in turn fixed in commit 56f396146af2 ("scsi: BusLogic: Fix 64-bit system enumeration error for Buslogic"), 8 years later, which shows that there are not a lot of users. Maciej is still using the driver on 32-bit hardware, and Khalid mentioned that the driver works with the device emulation used in VirtualBox and VMware. Both of those only emulate it for Windows 2000 and older operating systems that did not ship with the better LSI logic driver. Do a minimum fix that searches through the list of descriptors to find one that matches the bus address. This is clearly as inefficient as was indicated in the code comment about the lack of a bus_to_virt() replacement. A better fix would likely involve changing out the entire descriptor allocation for a simpler one, but that would be much more invasive.

scsi: ufs: Split the drivers/scsi/ufs directory

2022-05-20T00:27:37Z

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.

scsi: core: Rename CONFIG_BLK_SCSI_REQUEST to CONFIG_SCSI_COMMON

2021-07-29T02:24:27Z

CONFIG_BLK_SCSI_REQUEST is rather misnamed as it enables building a small amount of code shared by the SCSI initiator, target, and consumers of the scsi_request passthrough API. Rename it and also allow building it as a module.

scsi: blkcg: Fix application ID config options

2021-07-04T18:44:22Z

Commit d2bcbeab4200 ("scsi: blkcg: Add app identifier support for blkcg") introduced an FC_APPID config option under SCSI. However, the added config option is not used anywhere. Simply remove it. The block layer BLK_CGROUP_FC_APPID config option is what actually controls whether the application ID code should be built or not. Make this option dependent on NVMe over FC since that is currently the only transport which supports the capability.

Add a unique application identifier (i.e fc_app_id member) in blkcg. This allows identification of traffic belonging to an specific both on the host and in the fabric infrastructure. As an example, this allows the storage stack to uniquely identify traffic belong to particular virtual machine.
