Welcome Heidi, Margie, Jeremy, and Tom to the OpenStack Foundation team! <http://www.openstack.org/blog/2013/06/welcome-heidi-margie-jeremy-and-tom-t…> Since the Foundation launched last September, we’ve continued to build out a diverse team. This has been a big focus to keep up with the incredible growth in the OpenStack community with another new software release (Grizzly), the Portland Summit with over 2600 people (double San Diego!), and the start of the work to organize the first international Summit in Hong Kong (expecting over 4,000 people). To keep up with such amazing growth, we expanded the team with new roles to drive adoption of the software, support the development process and grow the OpenStack ecosystem. Heidi Bretz joined as Director of Business Development, Margie Callard as Marketing Manager, Jeremy Stanley as Infrastructure Engineer and Tom Fifield as User Community Manager. Openstack Grizzly with Nicira NVP Plugin Provider Router Use Case with NAT <http://www.cloudactual.com/2013/06/openstack-grizzly-with-nicira-nvp.html> This post by Thomas Kraus <http://www.cloudactual.com/search/label/openstack> reviews a common use-case for Openstack Networking and show step by step how to achieve the requirements for this use case using Openstack Networking in the Grizzly release with the Nicira Network Virtualization plugin for Openstack. The OpenStack Community Welcomes Developers in All Programming Languages <http://blog.phymata.com/2013/06/12/the-openstack-community-welcomes-develop…> If you ever encounter someone looking for help with any non-python language, you can always point them to the SDKs wiki page <https://wiki.openstack.org/wiki/SDKs>. They should be able to find their way from there. How non developers can contribute to OpenStack <http://www.muktware.com/5634/how-non-developers-can-contribute-openstack> One common question many of us involved in OpenStack receive is: “I am not a developer: how can I contribute to OpenStack?” Atul Jha wrapped up some possible answers to this question. OpenStack at EuroPython 2013 among Reinassance masterpieces <http://www.openstack.org/blog/2013/06/openstack-at-europython-2013-among-re…> If you ever wanted the chance to learn about OpenStack and see the masterpieces by Michelangelo, Brunelleschi, Leonardo, Ghiberti and so many others your best chance is to join us at Europython 2013 <https://ep2013.europython.eu/>. Hosted in Firenze July 1-7, Europython 2013 will see a massive OpenStack-related presence, including one half day training session to get started. The OpenStack Foundation will have a booth there and most likely a Help Desk session, where people interested can reserve time to talk to OpenStack experts in real life, under the Tuscan sun.

[OSSA 2013-015] Authentication bypass when using LDAP backend (CVE-2013-2157)

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA256 OpenStack Security Advisory: 2013-015 CVE: CVE-2013-2157 Date: June 13, 2013 Title: Authentication bypass when using LDAP backend Reporter: Jose Castro Leon (CERN) Products: Keystone Affects: Folsom, Grizzly Description: Jose Castro Leon from CERN reported a vulnerability in the way the Keystone LDAP backend authenticates users. When provided with an empty password, the backend would perform an anonymous LDAP bind that would result in successfully authenticating the user. An attacker could therefore easily impersonate and get valid tokens for any user. Only Keystone setups using LDAP authentication backend are affected.

OpenStack 2013.1.2 released <http://lists.openstack.org/pipermail/openstack-announce/2013-June/000109.ht…> The OpenStack Stable Maintenance team is happy to announce the release of the 2013.1.2 stable Grizzly release. We have been busy reviewing and accepting backported bugfixes to the stable/grizzly branches. A total of 80 bugs have been fixed across all core projects. *OpenStack “I” ***release******naming** <http://markmail.org/message/mz3c7thc4oa5vbfc> The next release cycle for OpenStack, starting in November 2013 after we conclude the current *release* cycle (“Havana”) will be called Icehouse. <https://launchpad.net/%7Eopenstack/+poll/i-release-naming> Open Source Sysadmin: Reorganization of the OpenStack Infrastructure Docs <http://princessleia.com/journal/?p=8101> The OpenStack Infrastructure team is constantly evolving its documentation to make it easier for new contributors to join the team. Last week documentation for the OpenStack Project Infrastructure <http://ci.openstack.org/> was reorganised “to re-orient the documentation as an introduction for new contributors and a reference for all contributors.” All of the CI tools are open source, the puppet and other configurations are all hosted in public revision control <https://github.com/openstack-infra/config> and any changes submitted are made by the same process all other changes in OpenStack are made <https://wiki.openstack.org/wiki/GerritWorkflow>. They go through automated tests in Jenkins to test applicable syntax and other formatting and the code changes submitted are reviewed by peers and approved by members of the infrastructure team. This has made it super easy it is for the team to collaborate on changes and offer suggestions (much better than endless pastebins or sharing a screen session with a fellow sysadmin!), plus with all changes in revision control it’s easy to track down where things went wrong and revert as necessary.

Havana-1 development milestone available <http://lists.openstack.org/pipermail/openstack-announce/2013-May/000107.html> The first milestone of the Havana development cycle, "havana-1? is now available for Keystone, Glance, Nova, Horizon, Networking, Cinder, Ceilometer, and Heat. It contains all the new features that have been added since the Grizzly pre-release Feature Freeze in March. Including the oslo libraries, 63 blueprints were implemented and 671 bugs were fixed during this milestone. The next development milestone, havana-2, is scheduled for July 18th. Further details by Julien Danjou for Ceilometer <http://julien.danjou.info/blog/2013/openstack-ceilometer-havana-1-milestone…> The challenge of the network <http://lorinhochstein.wordpress.com/2013/05/29/the-challenge-of-the-network/> Lorin Hochstein <http://lorinhochstein.wordpress.com/> shared a very detailed story about debugging the network in OpenStack-powered instances. The story starts with a familiar message: I can't connect to the instance. Hopefully his story will be shared by generations of new OpenStack users and become legend. Travel less, save more: introducing the OpenStack volume affinity filter <http://www.mirantis.com/blog/travel-less-save-more-introducing-openstack-vo…> It is a common desire to have some storage space associated with an instance running on cloud. It is also a common desire to have access to it be as fast as possible. OpenStack doesn't provide a way to fine-tune this particular option out of the box. Mirantis engineer Alexey Ovchinnikov <http://www.mirantis.com/author/alexey-ovchinnikov/> discusses how Mirantis implemented just such an extension, what roadblocks have already been encountered, and what problems one may encounter when using it. OpenStack leaders learning by humility, doing and being good partners <http://robhirschfeld.com/2013/05/28/openstack-leaders-learning-by-humility-…> Director Rob Hirschfeld <http://robhirschfeld.com/> shares his thoughts about OpenStack leadership, open source collaboration and community.

[OSSA 2013-014] Missing expiration check in Keystone PKI tokens validation (CVE-2013-2104)
by Thierry Carrez 28 May '13

28 May '13

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA256 OpenStack Security Advisory: 2013-014 CVE: CVE-2013-2104 Date: May 28, 2013 Title: Missing expiration check in Keystone PKI tokens validation Reporter: Eoghan Glynn (Red Hat), Alex Meade (Rackspace) Products/Affects: Keystone (Folsom only), python-keystoneclient (0.2.0+) Description: Eoghan Glynn from Red Hat and Alex Meade from Rackspace both reported a vulnerability in expiry checks for PKI tokens in the Keystone authentication middleware. Expired tokens for authenticated users could continue to be used, potentially resulting in the bypass of intended security policies. The effect of PKI token revocation is also reversed when the token expires, in the sense that a revoked token is once again treated as being valid. Only setups using PKI tokens are affected. Note: The affected code was added to Keystone in the Folsom release, but was moved to python-keystoneclient during the Grizzly development cycle. python-keystoneclient fix (will be included in upcoming 0.2.4 release): https://review.openstack.org/#/c/30742/ Keystone (Folsom) fix: https://review.openstack.org/#/c/30743/ References: https://bugs.launchpad.net/python-keystoneclient/+bug/1179615 http://www.cve.mitre.org/cgi-bin/cvename.cgi?name=2013-2104 - -- Thierry Carrez (ttx) OpenStack Vulnerability Management Team -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.12 (GNU/Linux) Comment: Using GnuPG with undefined - http://www.enigmail.net/ iQIcBAEBCAAGBQJRpRVGAAoJEFB6+JAlsQQjBRAP/iyScNAht67EMgGed4GWNKd3 2zHOgmqIq31S558ugul1e3qNgggnQ0qJvI1RjcgZuKoJEhH8SaPZBuykyycSvO9M L2Bex+GKAGAMuaz4ryPcnt7xJg+Mc0cksdCldeW1pXMrt8yITSQgXe0GqnGssoC+ 5TCk7JG8ADczbDGMa/nyc65tksbEI8hNJYyLLbCapvxfz4VqL2r5yp0vT0/jWDxy FLocAYnoKm9oxl0In5zioMQs0cSYAAa5EjwMLMMmUF/Axa7GskUOME8Q/GdgpMzJ h5AutinbpANSysz8pTB9bps7WSq33KfGKBN23caP43XvyMVA6CTsLUJH+U/9n+9u 0rTmKcumLXW9nkf5leki1u69VqRZFksrcEzJVtXdDyGGvFbZjPLcoA8lWifluSK/ vhu+T+RSnFWicki/Ifiz7c4tK6RYSB+a4G3/982GBxKp1sm3WLKd3ljsmpsqFeAY sz1o6p8zTgKIsYKrFEO6wMx37Qiga1RRB0As9msmAHJ6LXTO5ev8LcxXBjRjSIPs kTxoxHomRhbJAigvw+qSNSZz3DjrEywcqlNLLINQio21gzPMP4v1GVzwvroI8akf 6oz4DLDMcbdI1yQ7jjEhpnrcpFRHrJi2a45Tv6dlto34LvG7gLvgmLgnkJs0XMw7 BslUz5cGAucwXTz2vSHs =bu2N -----END PGP SIGNATURE-----

The OpenStack Summit is coming to Hong Kong <http://www.openstack.org/summit/openstack-summit-hong-kong-2013/> It's official: we're going to Hong Kong on Nov 5-8. The Summit will take place at Asia World Expo, a large convention center near the airport with a connecting Marriott hotel. The Airport Express train stops within Asia World Expo, making it convenient to access from most parts of the city. Please check the VISA information page <http://www.openstack.org/summit/openstack-summit-hong-kong-2013/visa-inform…> and FAQ <http://www.openstack.org/summit/openstack-summit-hong-kong-2013/conference-…> for more information about your travel plans. We encourage you to book early! Connecting the dots: Dell stays course on OpenStack private <http://robhirschfeld.com/2013/05/23/dell-stays-course-on-openstack-private-…> OpenStack Foundation board member Rob Hirschfeld <http://robhirschfeld.com/> summarizes the /increasing level of investment/ in OpenStack-powered private cloud solutions (Dell <http://jobs.dell/>is hiring! <http://jobs.dell.com/search/openstack/ASCategory/-1/ASPostedDate/-1/ASCount…>). Among the things highlighted, the recent announcements are about increasing investment where Dell is already successful <http://en.community.dell.com/dell-blogs/direct2dell/b/direct2dell/archive/2…> plus accelerating with new features (such as leadership in HyperV enablement <http://www.serverwatch.com/server-news/dell-sets-the-stage-for-hyper-vs-ret…>). An introductory tour of OpenStack Cloud Messaging as a Service <http://www.openstack.org/blog/2013/05/an-introductory-tour-of-openstack-clo…> The need for an OpenStack Messaging Service was recognized by the San Diego Grizzly Summit, and in an unconference track design meeting on the last day, a crowd of interested people met, talked out some requirements, and from that the OpenStack Message Bus <https://wiki.openstack.org/wiki/Marconi> project was born. It was codenamed "Marconi", in honor of Guglielmo Marconi <http://en.wikipedia.org/wiki/Guglielmo_Marconi>, the inventor of wireless messaging. The Marconi team collaborates on Launchpad <https://launchpad.net/marconi>. Working with the OpenStack Code Review and CI system -- Chef Edition <http://www.joinfu.com/2013/05/working-with-the-openstack-code-review-and-ci…> For too long, the state of the OpenStack Chef world had been one of duplicative effort, endless forks of Chef cookbooks, and little integration with how many of the OpenStack projects choose to control source code and integration testing. Recently, however, the Chef + OpenStack community has been getting its proverbial act together. Folks from lots of companies have come together and pushed to align efforts to produce a set of well-documented, flexible, but focused Chef cookbooks that install and configure OpenStack services. StackForge now hosting a set of Chef cookbooks for OpenStack. Virtualizing legacy hardware in OpenStack <http://dachary.org/?p=1991> Loïc Dachary <http://dachary.org/> summarizes how the French non-profit organization April <http://april.org/> migrated the workload of a five years old hardware to OpenStack. Instead of migrating each of the fourteen vservers <http://linux-vserver.org/> on a Debian GNU/Linux lenny <http://www.debian.org/releases/lenny/> running a *2.6.26-2-vserver-686-bigmem* linux individually to an OpenStack instance, it was decided that the vserver host would be copied over to an OpenStack instance. Discussion lists available in non-English languages <https://wiki.openstack.org/wiki/Community#Mailing_lists_in_local_languages> In order to support our growing international communities the OpenStack Infrastructure and the Community team worked to allow groups to create mailing lists in languages other than English. People interested in discussions in Italian <http://lists.openstack.org/cgi-bin/mailman/listinfo/openstack-it> and Vietnamese <http://lists.openstack.org/cgi-bin/mailman/listinfo/openstack-vi> can join the lists already. A request for a list to discuss in Spanish is pending <https://pending/>review <https://review.openstack.org/#/c/30495/> and other can be created if necessary following the instructions <https://wiki.openstack.org/wiki/Community#Mailing_lists_in_local_languages>.
