You will get initial configuration files in /etc/tomoyo/ directory.

Run init_policy.sh to perform initial configuration for ccs patch

/usr/lib/ccs/init_policy.sh

You will get initial configuration files in /etc/ccs/ directory.

Configure TOMOYO Linux to learn system behavior.

echo '<kernel>' > /etc/tomoyo/domain_policy.conf
echo 'use_profile 1' >> /etc/tomoyo/domain_policy.conf

When you boot with TOMOYO Linux kernel, you will see the following message when /sbin/init is about to start.

If you press 'Enter' key or wait for 10 seconds, TOMOYO Linux gets enabled and policy is loaded. If you have trouble such as unable to login because of inappropriate TOMOYO Linux configuration, enter "disable" and press 'Enter' key to disable TOMOYO Linux.

Login to the system as root user, and run editpolicy included in TOMOYO Linux tools.

=== Short Descriptions ===

{| style="text-align: left;"

!editpolicy
|Edits the current policy in /proc/ccs/ directory
|-valign="top"
!editpolicy_offline
|Edits the policy in /etc/ccs/ directory.
|-valign="top"
!setlevel
|Changes the current control level (i.e. writing to /proc/ccs/profile ) and displays the new control level.
|-valign="top"
!setprofile
|Assigns a profile to domains.

!ccstree
|Lists the domainnames of currently running processes belong to and the profile numbers the domains currently assigned to.

!savepolicy
|Saves the on-memory policy onto disk.
|-valign="top"
!makesyaoranconf
|Generates syaoran.conf, the configuration file for SYAORAN (the Tamper-Proof /dev filesystem). You can use SYAORAN filesystem if you want to run the system with read-only root fs or you want to prevent device files from tampering.
|-valign="top"
!ccs-auditd
|Reads from /proc/ccs/grant_log and /proc/ccs/reject_log and writes to the location given in the commandline parameters.
|-valign="top"
!sortpolicy
|Remove duplicated entry from logs written by "ccs-auditd".
|-valign="top"
!findtemp
|Reads domain policy from standard input and checks the existence of pathnames, and dumps the nonexistent pathnames.
|-valign="top"
!ld-watch
|Appends shared libraries to exception policy automatically using "allow_read" directive when the location of shared libraries in /etc/ld.so.cache has changed.
|-valign="top"
!ccs-queryd
|Detects policy violation and displays the access request. You can tell the system whether the access request should be granted (or granted and policy should be appended to grant the access request) or rejected after you validate the access request.

By running this program while updating packages, you can avoid errors due to insufficient permissions.

Never grant access requests unconditionally. The cause of policy violation is not always updating packages, but may by malicious requests by attackers. If you grant access requests caused by malicious requests by attackers, the system gets intruded.

To enable "delayed enforcing mode", you need to either set "ALLOW_ENFORCE_GRACE=1" in /proc/ccs/profile using "setlevel" command or assign a profile whose ALLOW_ENFORCE_GRACE is set to 1 to domains using "setprofile" command.

|-valign="top"
!checkpolicy
|Reads policy files from standard input and checks syntaxes.
|-valign="top"
!ccs-init
|Loads policy files from /etc/ccs/ directory.

Put this program as /sbin/ccs-init , and this program will be invoked automatically when execution of /sbin/init is requested by initrd.

Patch the kernel source:

patch -p1 -i ../sched-cfs-v2.6.22.9-v22.patch &&
patch -p1 -i ccs-patch-2.6.22.txt

Compile and install a new TOMOYO aware kernel. Ensure you enable the TOMOYO features.

=== 2.6.23 Kernel ===

http://tomoyo.sourceforge.jp/en/lkml-4/

The latest TOMOYO Linux patch is available at http://svn.sourceforge.jp/svnroot/tomoyo/tags/lkml/4/patches/ . Download it and extract it at the kernel source directory.

$ wget -O tomoyo.tar.gz 'http://svn.sourceforge.jp/cgi-bin/viewcvs.cgi/tags/lkml/4/patches.tar.gz?root=tomoyo&view=tar'
$ tar -zxvf tomoyo.tar.gz
$ /bin/sh -c 'for i in `cat patches/series`; do patch -p1 < patches/$i; done'

Edit Makefile's EXTRAVERSION= line if you need.

Next, create a kernel config with TOMOYO Linux enabled.

$ make -s menuconfig

Go to "Security options" screen and unselect "Default Linux Capabilities", "Root Plug Support", "NSA SELinux Support" and select "TOMOYO Linux support" as shown below.

[*] Enable different security models
< > Default Linux Capabilities
< > Root Plug Support
[ ] NSA SELinux Support
[*] TOMOYO Linux support

After creating a kernel config, compile the kernel.

$ make -s
# make -s modules_install install

Create initrd if you need. Edit /boot/grub/grub.conf or /boot/grub/menu.lst if you need.

=== Compiling TOMOYO Linux tools ===

You can download TOMOYO Linux tools at http://osdn.dl.sourceforge.jp/tomoyo/27220/ccs-tools-1.5.0-20070920.tar.gz . Download it and extract it and compile it. The tools are installed in /usr/lib/ccs .

$ wget -O tomoyo-tools.tar.gz 'http://osdn.dl.sourceforge.jp/tomoyo/27220/ccs-tools-1.5.0-20070920.tar.gz'
$ tar -zxf tomoyo-tools.tar.gz
$ cd ccstools
$ make
# make install

=== Initial Configuration ===

Run tomoyo_init_policy.sh included in TOMOYO Linux tools to perform initial configuration for patch from http://svn.sourceforge.jp/cgi-bin/viewcvs.cgi/tags/lkml/4/patches.tar.gz?root=tomoyo&view=tar.

# /usr/lib/ccs/tomoyo_init_policy.sh

You will get initial configuration files in /etc/tomoyo/ directory.

Run init_policy.sh included in TOMOYO Linux tools to perform initial configuration for patch from http://osdn.dl.sourceforge.jp/tomoyo/27219/ccs-patch-1.5.0-20070920.tar.gz

# /usr/lib/ccs/init_policy.sh

You will get initial configuration files in /etc/ccs/ directory.

=== Tutorial ===

Before starting tutorial, configure TOMOYO Linux to learn whole system behavior.

# echo '<kernel>' > /etc/tomoyo/domain_policy.conf
# echo 'use_profile 1' >> /etc/tomoyo/domain_policy.conf

When you boot with TOMOYO Linux kernel, you will see the following message when /sbin/init is about to start.

TOMOYO Linux: Enter 'disable' within 10 seconds to disable
TOMOYO Linux.
TOMOYO Linux>

If you press 'Enter' key or wait for 10 seconds, TOMOYO Linux gets enabled and policy is loaded. If you have trouble such as unable to login because of inappropriate TOMOYO Linux configuration, enter "disable" and press 'Enter' key to disable TOMOYO Linux.

Login to the system as root user, and run editpolicy included in TOMOYO Linux tools.

# /usr/lib/ccs/editpolicy
