After updating my kernel to sys-kernel/vanilla-sources-2.6.34, many services restricted using the TOMOYO LSM didn't work anymore. The reason is that 2.6.34's TOMOYO supports some additional restrictions (compared to 2.6.33). However, I am unable to configure the appropriate permissions because sys-apps/tomoyo-tools-2.2.0_p20090727 does not support those settings. According to the changelog, this could be solved by updating tomoyo-tools to 2.2.0-p20100225. Changelog entry: http://sourceforge.jp/projects/tomoyo/releases/41908/changelog
Bumped to 2.2.0_p20110211. Thanks.
