Title:
Cannot mount proc in unprivileged containers if /proc/xen is mounted
Status in linux package in Ubuntu:
Fix Committed
Status in linux source package in Xenial:
Fix Committed
Bug description:
SRU Justification
Impact: The xenfs filesystem is traditionally mounted at /proc/xen in
xen guests. This directory doesn't use the special "create proc
mountpoint" interface and thus fails the permanently empty test in
fs_fully_visible(). This causes mounting of proc to fail in user
namespace containers.
Fix: Use the special proc interface to make this a "permanently empty"
directory.
Regression potential: This change will make it impossible to create
files within /proc/xen, but since the directory is only ever used as a
mount point this should not cause any problems.
