Linux 3.1 is here

Filed under

Linus Torvalds has now released Linux kernel 3.1, tagging it in the git source code control system and uploading it to, but not, apparently announcing it in the mailing lists yet. Update: Torvalds has now announced by email the release of Linux 3.1. He and his colleagues have taken three months to produce this version. That's about three to four weeks longer than its predecessors – a consequence of the security breach at – putting the development of the Linux kernel significantly out of step.

Together with the current Nouveau driver code for Mesa and, this second kernel of the 3.x series will bring 3D acceleration on several current GeForce graphics chips.

  • European Parliament votes to extend Free Software security audits
    Remember how I raised €1 million to demonstrate security and freedom aren’t opposites? Well here’s what happened next and how we are going to move forward with this. In 2014, two major security vulnerabilities, Heartbleed and Shellshock, were discovered. Both concerned Free Software projects that are widely used throughout the Internet, on computers, tablets, and smartphones alike. My colleague Max Andersson from the Swedish Greens and I proposed a so-called “pilot project”, the Free and Open Source Software Audit (FOSSA).
  • Princeton Upskills U on Open Source Security
    During Wednesday's Upskill U course, lecturer Gary Sockrider, principal security technologist for Arbor Networks , explained the history of DDoS attacks, case studies of recent attacks, and the business impact of these security threats. DDoS attacks not only raise operational expenses, but can also negatively affect an organization's brand, and result in loss of revenue and customers. (Listen to Security: Tackling DDoS.) "Having visibility is key, you can't stop something you can't see. Having good visibility across your own network is vital in finding and stopping these attacks," said Sockrider. "You can leverage common tools and technology that are already available on the network equipment you own today such as flow technologies, looking at SIP logs … Obviously you'll want to get to some specific intelligent DDoS mitigation in the end."
