The file property has changed from 4.4.0-121 to 4.4.0-123
* 4.4.0-121:
$ ll /sys/module/apparmor/parameters/path_max
-rw-r--r-- 1 root root 4096 May 3 09:11
/sys/module/apparmor/parameters/path_max
* 4.4.0-123:
$ ll /sys/module/apparmor/parameters/path_max
-r--r--r-- 1 root root 4096 May 3 08:23
/sys/module/apparmor/parameters/path_max
This might be the cause of this permission denied issue.
So maybe it's the tool that needs some modification, I will add the qa-
regression-testing project to this bug as well.
