Antonio, I have a question about your 4.14 upstream commit 901ef845fa2469c ("selinux: allow per-file labeling for cgroupfs"). With that, I am no longer able to mount the cgroup2 filesystem with a 4.14 kernel. The problem is that your commit sets the SE_SBGENFS flag, which causes selinux to lookup the genfs database for a filesystem type match. However, the filesystem type "cgroup2" isn't in the genfs database in my RHEL7 based test system. The "cgroup" filesystem type is in the genfs database, so I have no problem with v1 cgroup mount. Do you know where the genfs database is defined? I need some way to add cgroup2 as a valid genfs fstype, or I have to manually back out the commit in order to do my cgroup2 testing. Thanks, Longman
