Hongbin Lu d412de7100 Introduce rootwrap and filter ... If the zun-compute process is owned by a user who doesn't have passwordless sudo privilege, zun-compute will fail to run privileged command (e.g. sudo privsep-helper ...). A native solution is to grant passwordless sudo to the user who owns the zun process, but the best practice is to leverage Rootwrap [1], which can restrict the privilege escalation. This patch make Zun leverage Rootwrap. In particular, it does the following: * Setup Rootwrap in the Zun devstack plugin * Introduce a sample rootwrap config file * Introduce sample rootwrap filters for executing privsep-helper * Introduce a root helper which basically adds "sudo zun-rootwrap" to the beginning of the command to be execute. * Initialize privsep to use the Zun's root helper [1] https://wiki.openstack.org/wiki/Rootwrap Closes-Bug: #1749342 Needed-By: I69c47d25fa53f8e08efad9daa71d2f550425a5e7 Change-Id: I3ca5d853588b3705cb6cb2410df16e16a621c030		2018-03-14 04:36:33 +00:00
