Thank you for your help Stephen. I have a couple of further questions: 1) The AVC is implemented as a hash-table as the avtab in the policydb. Unlike the latter, the structure involves hlist_node and hlist_head. Where are they defined? 2) I read that performance degradation due to SELinux is 5 to 7% as a rough guess. Would you say that the rule retrieval functionality (in general, from both the AVC and the policydb) can entail a significant role in such estimate, considering the whole system? What is the most functionality in SELinux? Thank you!
