Re: [PATCH] selftests/clone3: Check that the child exited cleanly

On 4/9/24 14:39, Mark Brown wrote:

When the child exits during the clone3() selftest we use WEXITSTATUS() to get the exit status from the process without first checking WIFEXITED() to see if the result will be valid. This can lead to incorrect results, for example if the child exits due to signal. Add a WIFEXTED() check and report any non-standard exit as a failure, using EXIT_FAILURE as the exit status for call_clone3() since we otherwise report 0 or negative errnos.
