scsi: csiostor: Convert sysfs snprintf() to sysfs_emit()

2022-09-16T02:35:21Z

Follow the advice of the Documentation/filesystems/sysfs.rst and show() should only use sysfs_emit() or sysfs_emit_at() when formatting the value to be returned to user space.

scsi: csio: Stop using the SCSI pointer

2022-02-23T02:11:04Z

Set .cmd_size in the SCSI host template instead of using the SCSI pointer from struct scsi_cmnd. This patch prepares for removal of the SCSI pointer from struct scsi_cmnd.

scsi: csiostor: Switch to attribute groups

2021-10-17T01:45:55Z

struct device supports attribute groups directly but does not support struct device_attribute directly. Hence switch to attribute groups. Link: https://lore.kernel.org/r/20211012233558.4066756-18-bvanassche@acm.org Signed-off-by: Bart Van Assche Signed-off-by: Martin K. Petersen

scsi: csiostor: Call scsi_done() directly

2021-10-17T01:28:46Z

Conditional statements are faster than indirect calls. Hence call scsi_done() directly. Link: https://lore.kernel.org/r/20211007202923.2174984-27-bvanassche@acm.org Signed-off-by: Bart Van Assche Signed-off-by: Martin K. Petersen

scsi: csiostor: Uninitialized data in csio_ln_vnp_read_cbfn()

2021-10-12T16:10:34Z

This variable is just a temporary variable, used to do an endian conversion. The problem is that the last byte is not initialized. After the conversion is completely done, the last byte is discarded so it doesn't cause a problem. But static checkers and the KMSan runtime checker can detect the uninitialized read and will complain about it.

scsi: csiostor: Add module softdep on cxgb4

2021-09-29T03:26:42Z

Both cxgb4 and csiostor drivers run on their own independent Physical Function. But when cxgb4 and csiostor are both being loaded in parallel via modprobe, there is a race when firmware upgrade is attempted by both the drivers. When the cxgb4 driver initiates the firmware upgrade, it halts the firmware and the chip until upgrade is complete. When the csiostor driver is coming up in parallel, the firmware mailbox communication fails with timeouts and the csiostor driver probe fails. Add a module soft dependency on cxgb4 driver to ensure loading csiostor triggers cxgb4 to load first when available to avoid the firmware upgrade race.
