I have just finished updating the user-space SE Linux code in Debian/Unstable to the version released on 2012-02-16. There were some changes to the build system from upstream which combined with the new Debian multi-arch support involved a fair bit of work for me. While I was at it I converted more of them to the new Quilt format to make it easier to send patches upstream. In the past I have been a bit slack about sending patches upstream, my aim for the next upstream release of user-space is to have at least half of my patches included upstream – this will make things easier for everyone.
Recently Mika Pflüger and Laurent Bigonville have started work on Debian SE Linux, they have done some good work converting the refpolicy source (which is used to build selinux-policy-default) to Quilt. Now it will be a lot easier to send policy patches upstream and porting them to newer versions of the upstream refpolicy.
Now the next significant thing that I want to do is to get systemd working correctly with SE Linux. But first I have to get it working correctly wit cryptsetup.
