Doc Text:	.Individual CephFS files and directories can now have SELinux labels The Ceph File System (CephFS) has recently enabled storing SELinux labels in the extended attributes of files. Previously, all files in a CephFS volume were labeled with a single common label `system_u:object_r:cephfs_t:s0`. With this enhancement, you can change the labels for individual files, and SELinux defines the labels of newly created files based on transition rules. Note that previously unlabeled files still have the `system_u:object_r:cephfs_t:s0` label until explicitly changed.	Story Points:	---

Description Ondrej Mosnacek 2020-04-14 12:53:51 UTC

As discussed in BZ 1814689, we want to enable CephFS to use xattr for storing labels, but at the same time keep cephfs_t as default label for files without a label (for backwards compatibility).

To enable this, we need to make small RHEL-only changes to the kernel and selinux-policy. This BZ tracks the kernel part - to add "ceph" to the list of filesystems for which combined genfs + xattrs labeling is used. The policy part is tracked in BZ 1814689.

What version of OCP did this RHSA make it into?
