scsi: arcmsr: Switch to attribute groups

2021-10-17T01:45:54Z

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/20211012233558.4066756-13-bvanassche@acm.org Signed-off-by: Bart Van Assche Signed-off-by: Martin K. Petersen

scsi: core: Remove the 'done' argument from SCSI queuecommand_lck functions

2021-10-17T01:32:16Z

The DEF_SCSI_QCMD() macro passes the addresses of the SCSI host lock and also that of the scsi_done function to the queuecommand_lck() function implementations. Remove the 'scsi_done' argument since its address is now a constant and instead call 'scsi_done' directly from inside the queuecommand_lck() functions.

scsi: arcmsr: Call scsi_done() directly

2021-10-17T01:28:45Z

Conditional statements are faster than indirect calls. Hence call scsi_done() directly. Link: https://lore.kernel.org/r/20211007202923.2174984-23-bvanassche@acm.org Signed-off-by: Bart Van Assche Signed-off-by: Martin K. Petersen

scsi: arcmsr: Avoid over-read of sense buffer

2021-06-19T03:26:33Z

In preparation for FORTIFY_SOURCE performing compile-time and run-time field bounds checking for memcpy(), memmove(), and memset(), avoid intentionally reading across neighboring array fields. pcmd->sense_buffer is 96 bytes, and was being manually zero-filled. However, struct SENSE_DATA is 18 bytes, with ccb->arcmsr_cdb.SenseData only being 15 bytes, resulting in a 3 byte over-read. Copy only the contents of ccb->arcmsr_cdb.SenseData and zero fill the remainder, avoiding potential over-reads.

scsi: core: Drop obsolete Linux-specific SCSI status codes

2021-06-01T03:59:18Z

Originally the SCSI subsystem has been using 'special' SCSI status codes, which were the SAM-specified ones but shifted by 1. As most drivers have now been modified to use the SAM-specified ones, having two nearly identical sets of definitions only causes confusion. The Linux-specifed SCSI status codes have been marked obsolete for several years so drop them and use the SAM-specified status codes throughout.

scsi: core: Kill DRIVER_SENSE

2021-06-01T02:48:21Z

Replace the check for DRIVER_SENSE with a check for scsi_status_is_check_condition(). Audit all callsites to ensure the SAM status is set correctly. For backwards compability move the DRIVER_SENSE definition to sg.h, and update sg, bsg, and scsi_ioctl to set the DRIVER_SENSE driver_status whenever SAM_STAT_CHECK_CONDITION is present.

scsi: arcmsr: Fix doorbell status being updated late on ARC-1886

2021-05-21T20:54:47Z

It is possible for the IOP to be delayed in updating the doorbell status. The doorbell status should not be 0 so loop until the value changes. Link: https://lore.kernel.org/r/afdfdf7eabecf14632492c4987a6b9ac6312a7ad.camel@areca.com.tw Signed-off-by: ching Huang Signed-off-by: Martin K. Petersen
