New OpenStack Security Notice

Nova and Cinder key manager for Barbican misuses cached credentials (OSSN 0063)

From the summary “During the Icehouse release the Cinder and Nova projects added a feature that supports storage volume encryption using keys stored in Barbican. The Barbican key manager, that is part of Nova and Cinder, had a bug that could cause an authorized user to lose access to an encryption key or allow the wrong user to gain access to an encryption key.”

More information and discussion in the original post or the OSSN itself.

Golang not to be given blanket approval for use in OpenStack

While it generated relatively little list traffic in the week past, the TC met and decided not to add golang to the list of official OpenStack development languages.  The door was however left open to accept its use on a project by project basis – in your humble correspondent’s opinion a reasonable middle ground.

The TC meeting minutes are here – the section in question starts at 20:20:04. You can also read the Change in question.  Last but by no means least Monty Taylor posted an eloquent rationale for his “no” vote here and is, I think, worthy of your time to read irrespective of your view on the matter – a nice demonstration of how to express a view on a contentious topic and respect differing views along the way.

StackViz – a neat Visualisation utility

Tim Buckley announced that StackViz has been enabled for all devstack-gate jobs and pointed interested parties at this example output.

As Tim describes it “StackViz is a visualization utility for generating interactive visualizations of jobs in the OpenStack QA pipeline and aims to ease debugging and performance analysis tasks. Currently it renders an interactive timeline for subunit results and dstat data, but we are actively working to visualize more log types in the future.”

The example output looks pretty slick and it’s had some glowing feedback on the list :)

Higgins now Zun

Hongbin Lu gave a heads up that the recently announced container management service Higgins is being renamed to Zun due to some project name overlaps.  The renaming thread itself kicked off late last month here in a post from Shu Mutou.
