I totally agree. Following the LKML discussion was interesting. LSM modules can indeed complement each other, and "chaining" of LSM modules can lead to increased security through the use of a variety of protection techniques. Perhaps things will change. Topics concerning security in the Linux Kernel always seem to generate extensive discussions. >> The latest patch I could find was here [1]. > > Yama is included in Ubuntu 10.10 and later kernels, in a way that both Yama and > one of SELinux/Smack/TOMOYO/AppArmor can be enabled at the same time. > You can get the latest version from > > http://kernel.ubuntu.com/git?p=ubuntu/ubuntu-maverick.git (2.6.35) > http://kernel.ubuntu.com/git?p=ubuntu/ubuntu-natty.git (2.6.37) Thanks for the links. Applying changes from ubuntu-natty to 2.6.36 might be a little harder, but I'll give it a go. Might even switch to 2.6.37-rc4 instead to make life easier. Kind regards
