From b748fc7a8763a5b3f8149f12c45711cd73ef8176 Mon Sep 17 00:00:00 2001 From: Jeff Layton Date: Tue, 28 Jul 2020 10:34:20 -0400 Subject: ceph: set sec_context xattr on symlink creation Symlink inodes should have the security context set in their xattrs on creation. We already set the context on creation, but we don't attach the pagelist. The effect is that symlink inodes don't get an SELinux context set on them at creation, so they end up unlabeled instead of inheriting the proper context. Make it do so.
