Subject: [PATCH 3/3] Enable security.selinux in user namespaces
Date: Thu, 22 Jun 2017 14:59:49 -0400	[thread overview]
Message-ID: <1498157989-11814-4-git-send-email-stefanb@linux.vnet.ibm.com> (raw)
In-Reply-To: <1498157989-11814-1-git-send-email-stefanb@linux.vnet.ibm.com>

Before the current modifications, SELinux extended attributes were
visible inside the user namespace but changes in patch 1 hid them.
This patch enables security.selinux in user namespaces and allows
them to be written to in the same way as security.capability.
