The total ata xfer length may not be calculated properly, in that we do not use the proper method to get an sg element dma length. According to the code comment, sg_dma_len() should be used after dma_map_sg() is called. This issue was found by turning on the SMMUv3 in front of the hisi_sas controller in hip07. Multiple sg elements were being combined into a single element, but the original first element length was being use as the total xfer length.

Reviewing the result of what was just added for Kconfig, we made a poor choice. It worked well for full kernel builds, but not so much for how it would be deployed on a distro. Here's the final result: - lpfc will compile in NVME initiator and/or NVME target support based on whether the kernel has the corresponding subsystem support. Kconfig is not used to drive this specifically for lpfc. - There is a module parameter, lpfc_enable_fc4_type, that indicates whether the ports will do FCP-only or FCP & NVME (NVME-only not yet possible due to dependency on fc transport). As FCP & NVME divvys up exchange resources, and given NVME will not be often initially, the default is changed to FCP only. Signed-off-by:

Hyper-V host emulation of SCSI for virtual DVD device reports SCSI version 0 (UNKNOWN) but is still capable of supporting REPORTLUN. Without this patch, a GEN2 Linux guest on Hyper-V will not boot 4.11 successfully with virtual DVD ROM device. What happens is that the SCSI scan process falls back to doing sequential probing by INQUIRY. But the storvsc driver has a previous workaround that masks/blocks all errors reports from INQUIRY (or MODE_SENSE) commands. This workaround causes the scan to then populate a full set of bogus LUN's on the target and then sends kernel spinning off into a death spiral doing block reads on the non-existent LUNs. By setting the correct blacklist flags, the target with the DVD device is scanned with REPORTLUN and that works correctly. Patch needs to go in current 4.11, it is safe but not necessary in older kernels. Signed-off-by:

Christoph's prior patch missed the template for the sli3 adapters, which is now the "no host reset" template. Add the transport eh_timed_out handler to the no host reset template Signed-off-by:
-
James Smart authored
A previous change unilaterally removed the hba reset entry point from the sli3 host template. This was done to allow tape devices being used for back up from being removed. Why was this done ? When there was non-responding device on the fabric, the error escalation policy would escalate to the reset handler. When the reset handler was called, it would reset the adapter, dropping link, thus logging out and terminating all i/o's - on any target. If there was a tape device on the same adapter that wasn't in error, it would kill the tape i/o's, effectively killing the tape device state. With the reset point removed, the adapter reset avoided the fabric logout, allowing the other devices to continue to operate unaffected. A hack - yes. Hint: we really need a transport I_T nexus reset callback added to the eh process (in between the SCSI target reset and hba reset points), so a fc logout could occur to the one bad target only and stop the error escalation process. This patch commonizes the approach so it can be used for sli3 and sli4 adapters, but mandates the admin, via module parameter, specifically identify which adapters the resets are to be removed for. Additionally, bus_reset, which sends Target Reset TMFs to all targets, is also removed from the template as it too has the same effect as the adapter reset. Signed-off-by:
