Ubuntu Hardy (8.04)

This guide is intended to build Ubuntu with Trusted Computing.

1. Install Ubuntu Desktop

Download ISO image. and install to your HDD.

Update to be work with latest packages.

Install additional packages, dpkg-dev, devscripts, fakeroot, pbuilder

2. Enable Integrity Measurements

2.1. Bootloader

2.1.1 GRUB-IMA

Download source package and test the build.

$ sudo apt-get build-dep grub
$ apt-get source grub
$ cd grub-0.97
$ debchange -i
$ dpkg-buildpackage -rfakeroot -us -uc

OK? Next apply the IMA patch.

Download source package and test the build.

TBD

Reboot

2.1.2 Trusted GRUB

http://sourceforge.net/projects/trustedgrub

$ wget http://jaist.dl.sourceforge.net/sourceforge/trustedgrub/TrustedGRUB-1.1.3.tgz
$ tar xvfz TrustedGRUB-1.1.3.tgz
$ cd  TrustedGRUB-1.1.3
$ ./build_tgrub.sh
$ cd  TrustedGRUB-1.1.3

$ ./configure CFLAGS="-fno-stack-protector" STAGE2_CFLAGS="-fno-stack-protector"
$ make
$ sudo make install

$ sudo /usr/local/sbin/grub-install /dev/sda

2.2. Linux

Download source package and test the build.

$ sudo apt-get build-dep linux-image-debug-2.6.24-12-generic
$ apt-get source linux-image-debug-2.6.24-12-generic
$ cd linux-2.6.24
$ debchange -i

$ cp /boot/config-2.6.24-12-generic .config
$ make oldconfig
UBUNTUBUILD=1 DEBIAN_SRCTOP=./ fakeroot make-kpkg -initrd kernel_image kernel_headers modules_image

$ dpkg-buildpackage -rfakeroot -us -uc

OK? Next, try to apply the Integrity Measurement patch.

2.2.1 Linux-IMA

This is original IMA patch using LSM. The patch is available from http://sourceforge.net/projects/linux-ima

$ sudo apt-get build-dep linux-image-debug-2.6.24-12-generic
$ apt-get source linux-image-debug-2.6.24-12-generic
$ cd linux-2.6.24
$ debchange -i

$ wget http://nchc.dl.sourceforge.net/sourceforge/linux-ima/ibm_ima_8.3_2.6.24.3.patch
$ patch -p1 --dry-run < ibm_ima_8.3_2.6.24.3.patch 

some failes, since the AppArmor patch was applied.

$ patch -p1 < ibm_ima_8.3_2.6.24.3.patch 

Manualy fix security/Kconfig and security/Makefile. 

$ cp /boot/config-2.6.24-12-generic .config
$ make -s menuconfig

$ UBUNTUBUILD=1 DEBIAN_SRCTOP=./ fakeroot make-kpkg -initrd kernel_image kernel_headers modules_image

$ cd ..
$ sudo dpkg -i linux-headers-2.6.24.3_2.6.24-13.23ubuntu1_i386.deb
$ sudo dpkg -i linux-image-2.6.24.3_2.6.24-13.23ubuntu1_i386.deb

Edit /boot/grub/menu.lst to enable IMA.

Reboot the system. and check the measurements

$ ls /sys/kernel/security/
