Fiddling with puppet apply

As part of a larger exercise, I am switching my local VM set from a more-or-less scripted manual configuration towards a fully Puppet-powered one. Of course, it still uses a lot of custom modules and is most likely too ugly to expose to the wider internet, but it does seem …

Gentoo Hardened progress meeting of march 2013

Another month has passed, so time for a new progress meeting...

Toolchain

GCC v4.7 has been unmasked, allowing a large set of users to test out the new GCC. It is also expected that GCC 4.8-rc1 will hit the tree next week. In the hardened-dev overlay, hardened support …

Uploading selinuxnode test VM

At the time of writing (but I'll delay the publication of this post a few hours), I'm uploading a new SELinux-enabled KVM guest image. This is not an update on the previous image though (it's a reinstalled system - after all, I use VMs for testing, so it makes sense to …

Working on a new selinuxnode VM

A long time ago, I made a SELinux enabled VM for people to play with, displaying a minimal Gentoo installation, including the hardening features it supports (PIE/PIC toolchain, grSecurity, PaX and SELinux). I'm currently trying to create a new one, which also includes IMA/EVM, but it looks like …

Transforming GuideXML to wiki

The Gentoo project has its own official wiki for some time now, and we are going to use it more and more in the next few months. For instance, in the last Gentoo Hardened meeting, we already discussed that most user-oriented documentation should be put on the wiki, and I've …

Gentoo Hardened goes onward (aka project meeting)

It's been a while again, so time for another Gentoo Hardened online progress meeting.

Toolchain

GCC 4.8 is on development stage 4, so the hardened patches will be worked on next week. Some help on it is needed to test the patches on ARM, PPC and MIPS though. For …

IMA and EVM on Gentoo, part 2

I have been playing with Linux IMA/EVM on a Gentoo Hardened (with SELinux) system for a while and have been documenting what I think is interesting/necessary for Gentoo Linux users when they want to use IMA/EVM as well. Note that the documentation of the Linux IMA/EVM …

Gentoo Hardened IMA support

Adventurous users, contributors and developers can enable the Integrity Measurement Architecture subsystem in the Linux kernel with appraisal (since Linux kernel 3.7). In an attempt to support IMA (and EVM and other technologies) properly, the System Integrity subproject within Gentoo Hardened was launched a few months ago. And now …

Switching policy types in Gentoo/SELinux

When you are running Gentoo with SELinux enabled, you will be running with a particular policy type, which you can devise from either /etc/selinux/config or from the output of the sestatus command. As a user on our IRC channel had some issues converting his strict-policy system to mcs …

Another hardened month has passed...

... so it's time for a new update ;-)

Toolchain

GCC 4.8 is still in its stage 3 development phase, so Zorry will send out the patches to the GCC development community when this phase is done. For Gentoo hardened itself, we now support all architectures except for IA64 (which never …
