TOMOYO Linux

TOMOYO Linux is a name-based MAC extension (LSM module) for the Linux kernel.

Changes since previous posting.

1. Removed d_realpath(). For now, TOMOYO uses __d_path().
2. Removed singly linked list. For now, TOMOYO uses standard doubly linked list
   with "struct rw_semaphore".
3. Fixed bitmap initialization error in tomoyo_update_single_path_acl().
4. Updated patch description.

How to try:

1. Apply patches and compile kernel with CONFIG_SECURITY_TOMOYO=y.
2. Download userspace tools (ccs-tools) available at
   http://sourceforge.jp/projects/tomoyo/releases/30298/ and
   extract and run 'make -C ccstools/ install' as root user.
3. Run /usr/lib/ccs/tomoyo_init_policy.sh as root user.
4. Run following commands to set learning-mode as default.
   (This step is optional but recommended on your first try.)
   # echo '<kernel>' > /etc/tomoyo/domain_policy.conf
   # echo 'use_profile 1' >> /etc/tomoyo/domain_policy.conf
5. Reboot.
   (If you compiled kernel with CONFIG_SECURITY_{SELINUX,SMACK}=y,
    add 'security=tomoyo' to kernel's command line.)
6. Run /usr/sbin/ccs-editpolicy to browse and edit policy.

LiveCD-based tutorials are available at
http://tomoyo.sourceforge.jp/en/1.6.x/1st-step/ubuntu8.04...
http://tomoyo.sourceforge.jp/en/1.6.x/1st-step/centos5-live/ .
Though these tutorials use non-LSM version of TOMOYO,
they are useful for you to know what TOMOYO is.

These patches are refreshed for
security-testing-2.6.git-27421e211a39784694b597dbf35848b88363c248.tar.gz ,
but should be applicable for 2.6.29-rc3 and later.

Regards.
