Open Source and Code Signing

Posted by on in Open Source

What is code signing

 

Code signing is the application of cryptographic hashes to code. Most people sign code in order to guarantee that no one has tampered with the code since publishing, and to explicitly be able to say that specific artifact originated somewhere. Most code signing relies on trusted third parties to effectively vouch for the identity of the signer. 

 

Open Source

 

Code signing isn’t really new, even in the open source world. Most Linux distributions have been signing their packages for years. But Linux distributions are fortunate in many ways. They own everything from the kernel to user land applications, and typically a user installs most if not all software via the distributions package repositories. This means you trust a code signing key shortly after or during installation for that distribution. Linux distribution users ‘trust’ packages that are signed by the same key as their installation medium. Most don’t check to verify that the signatures match what the project proclaims, but such verification is available.

Last night, the CloudStack Bay Area SF Users Group held a meetup in Palo Alto, CA at SAP Labs. Thank you to Alexander Graebe and SAP Labs for hosting our group yesterday evening!

John Kinsella kicked off the night with an introduction of speakers and ended the evening with a quick reminder about the CloudStack Collaboration Conference Europe held in Budapest, Hungary on November 19-22nd, 2014. The schedule is now available and the early bird registration deadline ends August 15th! Register now. ApacheCon Europe will be co-located with the CloudStack Collaboration Conference from November 17-21st, 2014.

Our guest speaker, Nitin Mehta, presented Replacing realhostip.com with your custom domain since Citrix will be ending RHIP on September 30th, 2014. Nitin helped CloudStackers understand the prerequisites, procedure and troubleshooting steps for customizing their cloud with their own domain. Currently Secondary Storage virtual machine (SSVM) and Console Proxy virtual machine (CPVM) use realhostip.com as default SSL domain for functionalities such as viewing virtual machine console, copying templates across zones, download template/iso/volume and these functionalities will be impacted with the shutdown of realhostip.com. Slides are available here. The video will be posted in about two weeks.

John Kinsella gave the talk, Don't Break the Glass! In Case of Emergency. The video can be found here.

Only last week, the Xen Project team was at OSCON where we launched Mirage OS 2.0 (event report to follow soon, but in the meantime check out the following sessions Nymote and Mirage, Floss Weekly on Mirage OS and Community War Stories) and now our Developer Summit is just round the corner. As we have seen tremendous community growth in the last 12 months (>30%) and the most feature reach Xen Project Hypervisor release coming up soon, I thought I'd share what you can expect.

What to expect?

Xen Project Developer Summits are packed with highly technical content where the core developers of the Xen Project community come together to discuss the evolution of the Xen Project. The conference is a mixture of talks and interactive sessions in un-conference format (which we call BoFs). Newcomers and those who are interested in the progress and future of the Xen Project, it's sub projects (Hypervisor on ARM and x86, Upstreams and Downstreams, Embedded and Automotive variants, Cloud Operating Systems such as Mirage OS) usually will get tremendous value from attending the event. Besides roadmap, feature updates and developer topics, this year features a few themes:

  • Network Function Virtualization
  • Security
  • Performance and Scalability
  • Cloud Operating Systems
  • Topics that are important for automotive/embedded/mobile use-cases, such as Real-time virtualization, certification and ARM support

Why not check out the agenda or watch last year's sessions to get a sense of what is coming. Note that BoF's and discussion groups will be published next week.

How to get the most out of the Summit?

Our developer events are designed to help you make connections and to participate. A good way to network are our evening social event and to network during the breaks. Another great way to get the most out of the summit is to submit a BoF/discussion groups about a topic you care about or to participate in a BoF/discussion group. BoF submissions are open until August 11 and the BoF schedule will be published the week before the event. Most of our talks will have an extensive and interactive Q&A portion, which is another way to engage.

Open Cloud Lounge

The Open Cloud Lounge was a comfy spot for OSCON attendees to hangout at. There were OpenDaylight, Apache CloudStack and Xen Project beanbags. Community members from the Xen Project and Apache CloudStack project handed out swag and cupcakes.
