The original error injection mechanism was based on scsi_host which
could not inject fault for a single SCSI device.
This patchset provides the ability to inject errors for a single
SCSI device. Now we supports inject timeout errors, queuecommand
errors, and hostbyte, driverbyte, statusbyte, and sense data for
specific SCSI Command.
The first two patch add an debugfs interface to add and inquiry single
device's error injection info; the third patch defined how to remove
an injection which has been added. The following 3 patches use the
injection info and generate the related error type.
V2:
- Using debugfs rather than sysfs attribute interface to manage error
Wenchao Hao (6):
scsi:scsi_debug: create scsi_debug directory in the debugfs filesystem
scsi:scsi_debug: Add interface to manage single device's error inject
scsi:scsi_debug: Define grammar to remove added error injection
scsi:scsi_debug: timeout command if the error is injected
scsi:scsi_debug: Return failed value if the error is injected
scsi:scsi_debug: set command's result and sense data if the error is
injected
