scsi: aacraid: Insure we don't access PCIe space during AER/EEH

2019-03-26T02:19:01Z

There are a few windows during AER/EEH when we can access PCIe I/O mapped registers. This will harden the access to insure we do not allow PCIe access during errors Signed-off-by: Dave Carroll Reviewed-by: Sagar Biradar Signed-off-by: Martin K. Petersen

scsi: ata: Use unsigned int for cmd's type in ioctls in scsi_host_template

2019-02-08T22:33:00Z

Clang warns several times in the scsi subsystem (trimmed for brevity): drivers/scsi/hpsa.c:6209:7: warning: overflow converting case value to switch condition type (2147762695 to 18446744071562347015) [-Wswitch] case CCISS_GETBUSTYPES: ^ drivers/scsi/hpsa.c:6208:7: warning: overflow converting case value to switch condition type (2147762694 to 18446744071562347014) [-Wswitch] case CCISS_GETHEARTBEAT: ^ The root cause is that the _IOC macro can generate really large numbers, which don't fit into type 'int', which is used for the cmd parameter in the ioctls in scsi_host_template. My research into how GCC and Clang are handling this at a low level didn't prove fruitful. However, looking at the rest of the kernel tree, all ioctls use an 'unsigned int' for the cmd parameter, which will fit all of the _IOC values in the scsi/ata subsystems. Make that change because none of the ioctls expect a negative value for any command, it brings the ioctls inline with the reset of the kernel, and it removes ambiguity, which is never good when dealing with compilers.

scsi: remove unneeded header search paths

2019-01-29T06:22:21Z

I was able to build without these extra header search paths. Especially, the header search path -I. in kernel Makefiles is always suspicious; it allows the compiler to search for headers in the top of $(srctree), where obviously no header file exists.

scsi: communicate max segment size to the DMA mapping code

2019-01-23T01:40:59Z

When a host driver sets a maximum segment size we should not only propagate that setting to the block layer, which can merge segments, but also to the DMA mapping layer which can merge segments as well.

scsi: flip the default on use_clustering

2018-12-19T04:13:12Z

Most SCSI drivers want to enable "clustering", that is merging of segments so that they might span more than a single page. Remove the ENABLE_CLUSTERING define, and require drivers to explicitly set DISABLE_CLUSTERING to disable this feature. Signed-off-by: Christoph Hellwig Signed-off-by: Martin K. Petersen
