This patch against 2.6.6-rc1-mm1 removes a hardcoded policy assumption from the get_user_sids logic in the SELinux module that was preventing it from returning contexts that had the same type as the caller even if the policy allowed such a transition. The assumption is not valid for all policies, and can be handled via policy configuration and userspace rather than hardcoding it in the module logic.
