[PATCH 0/5]scsi:scsi_debug: Add error injection for single device

From: Wenchao Hao
Date: Thu Mar 23 2023 - 07:57:42 EST


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 patch add an sysfs interface to add and inquiry single
device's error injection info; the second 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.

Wenchao Hao (5):
scsi:scsi_debug: Add sysfs interface to manage scsi devices' error
injection
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
