TOMOYO Linux on MeeGo 1.1
This page describes how to run TOMOYO Linux on MeeGo.
- Step 1: Setting up environment for emulator
- Step 2: Compiling kernel and tools
- Step 3: Initializing TOMOYO Linux
- Step 4: Analyzing MeeGo environment
Step 1: Setting up environment for emulator
Download and extract a MeeGo handset UI image file.
$ cd $ wget http://download3.meego.com/sep03/meego-handset-ia32-1.0.80.9.20100706.1-sdk-pre0901.tar.bz2 $ tar -jxf meego-handset-ia32-1.0.80.9.20100706.1-sdk-pre0901.tar.bz2 --strip 1
"root" user's password for this image file is "meego".
If you are going to use this image file on QEMU, download and install qemu-gl package as shown in http://wiki.meego.com/MeeGo_SDK_with_QEMU .
$ wget http://download3.meego.com/qemu-gl_0.12.4-3_i386.deb $ sudo dpkg -i qemu-gl_0.12.4-3_i386.deb $ wget http://download3.meego.com/qemugl_cmd.sh $ chmod 755 qemugl_cmd.sh
You can boot QEMU like below.
$ ./qemugl_cmd.sh meego-handset-ia32-1.0.80.9.20100706.1-sdk-pre0901.raw
If the MeeGo environment shows up correctly, you can proceed to step 2.
If you are going to use this image file on VMware, you need to modify this image file a bit.
First, create a VMware virtual machine with 4GB of virtual hard disk.
Next, boot the virtual machine using LiveCD. For example, you can use http://releases.ubuntu.com/lucid/ubuntu-10.04.2-desktop-i386.iso (MD5: 477350cbea8936c63d587cf2be69181b). If you booted using this ISO file, start the gnome terminal and become "root".
$ sudo bash
Check the virtual hard disk's device name. Below case shows that /dev/sda is the virtual hard disk.
# fdisk -l
Disk /dev/sda: 4294 MB, 4294967296 bytes 255 heads, 63 sectors/track, 522 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0x00000000 Disk /dev/sda doesn't contain a valid partition table
Retrieve this image file using ssh (or curl or wget or whatever) and write to virtual hard disk. Substitute below vmwarehost with VMware host's IP address.
# ssh root@vmwarehost 'cat ~/meego-handset-ia32-1.0.80.9.20100706.1-sdk-pre0901.raw' > /dev/sda # fdisk /dev/sda

Then, mount the first partition of the virtual hard disk on /mnt/ .

If the MeeGo environment shows up correctly, you can proceed to step 2. If it doesn't, check below things.
Login to the MeeGo environment via SSH using password "meego".
$ ssh root@meegohost
Then, check /var/log/Xorg.log.0 for (EE) lines. If you found "ioctl EVIOCGNAME failed: Inappropriate ioctl for device" line like below, you might need to let X ignore that device.

Do troubleshooting now before proceeding to next step.
Step 2: Compiling kernel and tools
Set up environment for compiling kernel and tools. This section assumes Fedora 13 in order to use "rpmbuild" command.
First, install packages needed for compiling.
$ su - # yum -y install wget gcc rpm-build elfutils-libelf-devel binutils-devel newt-devel ncurses-devel # exit
Next, download a kernel source package.
$ cd $ wget https://repo.meego.com/MeeGo/builds/1.0.99/1.0.99.2.20101019.1/core/repos/source/kernel-2.6.35.3-10.3.src.rpm
Next, install the package and run preparation stage.
$ rpm -ivh kernel-2.6.35.3-10.3.src.rpm $ rpmbuild -bp ~/rpmbuild/SPECS/kernel.spec $ cd ~/rpmbuild/BUILD/kernel-2.6.35.3/linux-2.6.35/
If you are going to use this kernel on QEMU, download and apply kernel patch. If you are going to use this kernel on VMware, you don't need to do this.
$ wget http://meego.gitorious.org/meego-developer-tools/meego-emulator-virtiogl-x86/blobs/raw/master/linux-2.6.35-virtio-for-qemu-gl-acceleration.patch $ patch -p1 < linux-2.6.35-virtio-for-qemu-gl-acceleration.patch
Next, create a kernel config file. You can pull it from the MeeGo environment on QEMU by doing
$ scp -p -P 6666 root@127.0.0.1:/boot/config-\* .config
or from the MeeGo environment on VMware by doing
$ scp -p root@meegohost:/boot/config-\* .config
Now, update the kernel config file. If you are going to use this kernel on QEMU, be sure to answer "y" or "m" to "Virtio userspace memory transport".
$ make -s oldconfig
MeeGo kernel is using writeback mode for mounting ext3 filesystem image. But use of writeback mode will corrupt files (e.g. data from deleted files is implicitly imported to previously written files) when QEMU or VMware is suddenly terminated. Change kernel config like below if you want to use ordered mode for mounting ext3 filesystem image.
$ sed -i -e 's/# CONFIG_EXT3_DEFAULTS_TO_ORDERED is not set/CONFIG_EXT3_DEFAULTS_TO_ORDERED=y/' -- .config
If you don't mean to debug kernel, you can save compilation time and disk space. Change kernel config like below if you don't mean to debug kernel.
$ sed -i -e 's/CONFIG_DEBUG_INFO=y/# CONFIG_DEBUG_INFO is not set/' -- .config
Next, download and apply TOMOYO Linux kernel patch.
$ wget https://sourceforge.net/projects/tomoyo/files/ccs-patch/1.8/ccs-patch-1.8.11-20240715.tar.gz $ wget https://sourceforge.net/projects/tomoyo/files/ccs-patch/1.8/ccs-patch-1.8.11-20240715.tar.gz.asc $ gpg ccs-patch-1.8.11-20240715.tar.gz.asc $ tar -zxf ccs-patch-1.8.11-20240715.tar.gz $ patch -p1 < patches/ccs-patch-2.6.35.diff $ cat config.ccs >> .config
Now, build the kernel.
$ make -s
Download and build the tools.
$ cd ~/rpmbuild/BUILD/ $ wget https://sourceforge.net/projects/tomoyo/files/ccs-tools/1.8/ccs-tools-1.8.9-20210910.tar.gz $ wget https://sourceforge.net/projects/tomoyo/files/ccs-tools/1.8/ccs-tools-1.8.9-20210910.tar.gz.asc $ gpg ccs-tools-1.8.9-20210910.tar.gz.asc $ tar -zxf ccs-tools-1.8.9-20210910.tar.gz $ make -sC ccs-tools/
Create a directory for temporarily holding kernel and tools and copy them.
$ su # mkdir -p /tmp/meego/boot/extlinux/ # make -sC ccs-tools/ INSTALLDIR=/tmp/meego/ install # cd kernel-2.6.35.3/linux-2.6.35/ # make -s INSTALL_MOD_PATH=/tmp/meego/ modules_install vdso_install # make -s INSTALL_PATH=/tmp/meego/boot/extlinux/ install # chmod -R go-w /tmp/meego/ # chown -R root:root /tmp/meego/ # exit
Copy the kernel and tools. You can push them to the MeeGo environment on QEMU by doing
$ cd /tmp/meego/ $ tar -zcf - | ssh root@127.0.0.1 -p 6666 'cd / && tar -zxf -'
or to the MeeGo environment on VMware by doing
$ cd /tmp/meego/ $ tar -zcf - | ssh root@meegohost 'cd / && tar -zxf -'
Step 3: Initializing TOMOYO Linux
Log in to the MeeGo environment via SSH.
Initialize TOMOYO Linux's configuration.
# /usr/lib/ccs/init_policy --use_profile=1
Change bootloader configuration.
# vi /boot/extlinux/extlinux.conf
Edit extlinux.conf like below.
--- extlinux.conf +++ extlinux.conf @@ -18,7 +18,7 @@ menu color timeout 0 #ffffffff #00000000 menu color cmdline 0 #ffffffff #00000000 label meego0 - menu label MeeGo (2.6.35~rc6-134.1-qemu) - kernel vmlinuz-2.6.35~rc6-134.1-qemu - append ro root=/dev/sda1 quiet vga=current quiet + menu label MeeGo (2.6.35.3) + kernel vmlinuz-2.6.35.3 + append ro root=/dev/sda1 vga=current menu default
Save the file and reboot the MeeGo environment.
# reboot
Step 4: Analyzing MeeGo environment
You can operate from SSH session. You can switch to console screen by pressing Alt+F1 key and switch back to graphical screen by Alt+F2 key if you removed "quiet" options from /boot/extlinux/extlinux.conf . Also, you may locate xterm window on graphical screen by doing
# export DISPLAY=:0
# xterm -into `xwininfo -root -tree -int | awk ' { if ( index($2, "duihome") > 0) print $1; } '`
Below movie demonstrates how you can use TOMOYO Linux for analyzing the MeeGo environment.
