Any chance to use the latest 7.1 policy builds? We should have some fixes in these 7.1 builds. I upgraded to selinux-policy-3.13.1-2.el7.noarch, and it seems prelink avcs still exists but alsactl avcs are gone.

Milos, could we open a new bug for these cron AVCS? Let's focus on prelink_t { setattr } AVCs here. The alsa_t { read } AVCs are already addressed in BZ#1149130.
Following AVCs appeared on my VM after prelink installation and crond restart:
