Description
This testcase checks whether kpartx will crash when called with invalid options. It is reported in fixed bug that when kpartx was passes something other than a file or a block device or a badly formed pathname, it could read off the end of the device string, and crash. The test steps include:1)install device-mapper device-mapper-multipath 2)restart multipathd service 3)kpartx -l / 4)check dmesg if there is segmentation fault
How to test
1. Ensure the device-mapper-multipath package is installed
Execute:dnf -y install device-mapper device-mapper-multipathExecute:rpm -qa
2. Execute the following command to generate the configuration file:
Execute:mpathconf --enable
3. Restart multipathd service
Execute:service multipathd restart
4. kpartx called with invalid options /
Execute:kpartx -l /
5. sleep 1 second
Execute:sleep 1
6. check dmesg if there is segmentation fault
Execute:dmesg
Expected Results
- no Segmentation fault, kpartx no longer crashes when called with invalid options.
