Description of problem: SELinux policies block ldconfig from writing data to the screen if logged in to a PTS. It also appears to block access to newly created system directories. Version-Release number of selected component (if applicable): hera# rpm -q --whatprovides `which ldconfig` glibc-2.6-3 hera# rpm -qa |grep selinux libselinux-python-2.0.13-1.fc7 selinux-policy-targeted-2.6.4-8.fc7 libselinux-2.0.13-1.fc7 selinux-policy-2.6.4-8.fc7 How reproducible: Always. Steps to Reproduce: 1. ldconfig -v 2. tail /var/log/audit/audit.log 3. Actual results: ldconfig does not output data when using -v during a rebuild of the ld.so cache or -p to print the contents of it. The audit logs show this is because SELinux is blocking it from accessing the pts used by my login. Expected results: -v should display verbose information as ldconfig builds the cache -p should display the contents of the cache.
