The week of September 20th is going to be a busy one with both LinuxCon and the Linux Plumbers Conference co-located in Portland, Oregon. However, having both conferences in the same place on the same week should make it much easier for people to justify the travel. If you are planning on attending one or both of the conferences you should know that each conference has a dedicated security track or mini-summit which you probably want to attend (and submit a proposal too!).
On the day before LinuxCon starts, we will be holding this year's SELinux Developer's Summit. The SELinux Developer Summit is always a great opportunity to meet several of the SELinux developer's in person and discuss anything and everything SELinux. To get a better idea of what to expect you can check out the main page and talks from last year. For those of you interested in presenting a topic this year, the Call for Proposals is open until July 1st, so get your abstract in soon.
During the Linux Plumbers Conference there will be a dedicated security track for anything related to Linux security. The security track is new this year and promises to have some interesting talks, if you would like to add to that list James Morris put together a nice post with all the information you need; just beware the deadline for new proposals is June 15th.
