"TOMOYO Linux" is our work in the field of security enhancement for Linux.
This is the 6th submission of TOMOYO Linux.
(http://tomoyo.sourceforge.jp/wiki-e/?WhatIs#mainlining)
Changes since previous (November 17th) submission:
* Added security goal document. (Documentation/TOMOYO.txt)
This document is intended to specify the security goal that TOMOYO
Linux is trying to achieve. Thread URL:
http://lkml.org/lkml/2007/12/25/18
* Added environment variable name control functionality.
Users can restrict the environment variable's names passed to
execve() for each domain.
* Refreshed patches for the latest -mm tree.
Patches are for 2.6.24-rc6-mm1
The possibility of AB-BA deadlock has been pointed out and argued in
http://lkml.org/lkml/2007/11/5/388 .
We believe that LSM functions shouldn't access namespace_sem, so
we chose to write a set of wrapper functions to pass "struct vfsmount" to
LSM functions using "struct task_struct". This method is suggested at
http://www.mail-archive.com/linux-security-module@vger.kernel.org/msg01712.html .
We wish Linux to merge either AppArmor's "Pass struct vfsmount to ..." patches or
our patches marked as [02/21], [03/21], [04/21] into mainline kernel
so that AppArmor and TOMOYO Linux can safely access "struct vfsmount" from LSM.
Patches consist of five types.
* [TOMOYO 01/21]: Documentation.
* [TOMOYO 02-05/21]: Essential modifications against -mm kernel.
* [TOMOYO 06-19/21]: LSM implementation of TOMOYO Linux.
* [TOMOYO 20/21]: Makefile and Kconfig.
* [TOMOYO 21/21]: Optional modifications against -mm kernel.
We are trying to make a fair
