2019-02-01scsi: aic94xx: fix module loadingJames Bottomley1-4/+4
The aic94xx driver is currently failing to load with errors like sysfs: cannot create duplicate filename '/devices/pci0000:00/0000:00:03.0/0000:02:00.3/0000:07:02.0/revision' Because the PCI code had recently added a file named 'revision' to every PCI device. Fix this by renaming the aic94xx revision file to aic_revision. This is safe to do for us because as far as I can tell, there's nothing in userspace relying on the current aic94xx revision file so it can be renamed without breaking anything.

2019-01-29scsi: hisi_sas: Fix losing directly attached disk when hot-plugXiaofei Tan4-9/+56
Hot-plugging SAS wire of direct hard disk backplane may cause disk lost. We have done this test with several types of SATA disk from different venders, and only two models from Seagate has this problem, ST4000NM0035-1V4107 and ST3000VM002-1ET166. The root cause is that the disk doesn't send D2H frame after OOB finished. SAS controller will issue phyup interrupt only when D2H frame is received, otherwise, will be waiting there all the time. When this issue happen, we can find the disk again with link reset. To fix this issue, we setup an timer after OOB finished. If the PHY is not up in 20s, do link reset.

2019-01-29scsi: hisi_sas: remove the check of sas_dev status in hisi_sas_I_T_nexus_reset()Xiang Chen3-16/+0
When issing a hardreset to a SATA device when running IO, it is possible that abnormal CQs of the device are returned. Then enter error handler, it doesn't enter function hisi_sas_abort_task() as there is no timeout IO, and it doesn't set device as HISI_SAS_DEV_EH. So when hardreset by libata later, it actually doesn't issue hardreset as there is a check to judge whether device is in error. For this situation, actually need to hardreset the device to recover. So remove the check of sas_dev status in hisi_sas_I_T_nexus_reset(). Before we add the check to avoid the endless loop of reset for directly-attached SATA device at probe time, actually we flutter it for it, so it is not necessary to add the check now.

When injecting 2 bit ECC error, it will cause fatal AXI interrupts. Before the recovery of SAS controller reset, the internal of SAS controller is in error. If CQ interrupts return at the time, actually it is exception CQ interrupt, and it may cause resource release in disorder. To avoid the exception situation, shutdown AXI bus after fatal AXI interrupt. In SAS controller reset, it will restart AXI bus. For later version of v3 hw, hardware will shutdown AXI bus for this situation, so just fix current ver of v3 hw.

2019-01-29scsi: prefix header search paths with $(srctree)/Masahiro Yamada2-2/+2
Currently, the Kbuild core manipulates header search paths in a crazy way [1]. To fix this mess, I want all Makefiles to add explicit $(srctree)/ to the search paths in the srctree. Some Makefiles are already written in that way, but not all. The goal of this work is to make the notation consistent, and finally get rid of the gross hacks.

The issue to be fixed in this commit is when libfc found it received a invalid FLOGI response from FC switch, it would return without freeing the fc frame, which is just the skb data. This would cause memory leak if FC switch keeps sending invalid FLOGI responses. This fix is just to make it execute `fc_frame_free(fp)` before returning from function `fc_lport_flogi_resp`.
