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-multipath Execute:rpm -qa
Expected Results
- no Segmentation fault, kpartx no longer crashes when called with invalid options.
