FYI, we added some basic userns capability smarts to SELinux in Linux 4.7. commit 8e4ff6f228e4722cac74db716e308d1da33d744f Author: Stephen Smalley <[email protected]> Date: Fri Apr 8 13:52:00 2016 -0400 selinux: distinguish non-init user namespace capability checks Distinguish capability checks against a target associated with the init user namespace versus capability checks against a target associated with a non-init user namespace by defining and using separate security classes for the latter. This is needed to support e.g. Chrome usage of user namespaces for the Chrome sandbox without needing to allow Chrome to also exercise capabilities on targets in the init user namespace.
