[libvirt] [PATCH 4/8] Avoid unsafe use of /proc/$PID/root in LXC disk hotplug

2014-02-17 Thread Daniel P. Berrange

Rewrite lxcDomainAttachDeviceDiskLive function to use the virProcessRunInMountNamespace helper. This avoids risk of a malicious guest replacing /dev with a absolute symlink, tricking the driver into changing the host OS filesystem. Signed-off-by: Daniel P. Berrange berra...@redhat.com ---
