When we write kernel code, testing it thoroughly by giving different input combinations to check all the vulnerabilities and code coverage is important. Also, running buggy code directly on the hardware board has the potential to break the device. The presentation covers building and running a KCOV-enabled kernel in a virtualized environment for runtime detection of error conditions and checking code coverage using the same. To develop a deeper understanding, we will inject faults from user space via debugfs and catch the same by fuzzing the Linux kernel. Further debugging will be shown by using the GCC utilities like addr2line, objdump, etc.
