parentTOMOYO: Add pathname aggregation support. (diff)
TOMOYO: Update profile structure.
This patch allows users to change access control mode for per-operation basis. This feature comes from non LSM version of TOMOYO which is designed for permitting users to use SELinux and TOMOYO at the same time. SELinux does not care filename in a directory whereas TOMOYO does. Change of filename can change how the file is used. For example, renaming index.txt to .htaccess will change how the file is used. Thus, letting SELinux to enforce read()/write()/mmap() etc. restriction and letting TOMOYO to enforce rename() restriction is an example usage of this feature. What is unfortunate for me is that currently LSM does not allow users to use SELinux and LSM version of TOMOYO at the same time...
