Summary

In the Linux kernel, the following vulnerability has been resolved: landlock: Fix warning from KUnit tests get_id_range() expects a positive value as first argument but get_random_u8() can return 0. Fix this by clamping it. Validated by running the test in a for loop for 1000 times. Note that MAX() is wrong as it is only supposed to be used for constants, but max() is good here.
