In security_get_user_sids, move the transition permission checks outside of the section holding the policy rdlock, and use the AVC to perform the checks, calling cond_resched after each one. These changes should allow preemption between the individual checks and enable caching of the results. It may however increase the overall time spent in the function in some cases, particularly in the cache miss case. The long term fix will be to take much of this logic to userspace by exporting additional state via selinuxfs, and ultimately deprecating and eliminating this interface from the kernel.
