The bug you are experiencing was fixed in TOMOYO 1.6.8p3 . Therefore, possible solution for your current kernel is to disable "allow_env" checking. To disable "allow_env" checking, please change mode of MAC_FOR_ENV lines in /etc/ccs/profile.conf to "disabled" and reload /etc/ccs/profile.conf . # sed -i -e 's/MAC_FOR_ENV=.*/MAC_FOR_ENV=disabled/' /etc/ccs/profile.conf # ccs-loadpolicy p Materials on TOMOYO 1.6.x is at http://tomoyo.sourceforge.jp/1.6/ .
