Since my last SE Linux in Debian status report [1] there have been some significant changes. Policy Last year I reported that the policy wasn’t very usable, on the 18th of January I uploaded version 2:2.20110726-2 of the policy packages that fixes many bugs. The policy should now be usable by most people for desktop […] On the 1st of August I noticed that the server which runs my blog among other things was having an occasional SEGV from a sshd process. Unfortunately I was busy and didn’t pay much attention to this, which turned out to be a big mistake. On the 12th of September I started investigating this properly […] There has been a lot of discussion recently about the recent Microsoft ideas regarding secure boot, in case you have missed it Michael Casadevall has written a good summary of the issue [1]. Recently I’ve seen a couple of people advocate the concept of secure boot with the stated idea that “root” should be unable […] Debian/Unstable Development deb http://www.coker.com.au wheezy selinux The above APT sources.list line has my repository for SE Linux packages that have been uploaded to Unstable and which will eventually go to testing and then the Wheezy release (if they aren’t obsoleted first). I have created that repository for people who want to track SE Linux development […] In December 2010 a paper was published by Robert N.M. Watson and Jonathan Anderson from the Cambridge University and Ben Laurie and Kris Kennaway of Google about the Capsicum capabilities system [1]. It seems that the aim of the project is to allow systems that need privileges briefly when they start (such as tcpdump) a […] In my previous post I expressed a desire to use regular expressions for files that may appear in multiple places in the tree due to bind mounts for /run and /var/run etc [1]. However there is a problem with this idea. The SE Linux file labeling program restorecon reads the file /etc/selinux/$SELINUXTYPE/contexts/files/file_contexts which contains a […] Currently Debian/Unstable is going through a transition to using /run instead of /var/run. Naturally any significant change to the filesystem layout requires matching changes to SE Linux policy. We currently have Debian bug #626720 open about this. Currently the initscripts package breaks selinux-policy-default in Debian/Unstable so that you can’t have initscripts using /run if the […] There is always been an ongoing debate about how to assign disk space into multiple partitions. I think that nowadays the best thing to do is to assign about 10G for the root filesystem for every desktop and server system because 10G is a small fraction of the disk space available (even the smallest laptops […] Guido Trentalancia started an interesting discussion on the SE Linux policy development list about how to manage the evolution of the policy [1]. The Problem The SE Linux policy is the set of rules that determine what access is granted. It assigns types to files and domains to processes and has a set of rules […] I’ve just updated my SE Linux repository for Squeeze to better support running mplayer on the i386 architecture, below is the APT sources.list line: deb http://www.coker.com.au squeeze selinux The first issue is a bug in the compilation of the SDL libraries which makes them request an executable stack (bug #613535). Recompiling the libraries on my […] |
