Description of problem: After upgrading selinux-policy-mls, yum threw the following error messages: Updating : selinux-policy-mls-3.13.1-224.fc26.noarch 53/156 /etc/selinux/mls/contexts/files/file_contexts.bin: line 1 error due to: Non-ASCII characters found /etc/selinux/mls/contexts/files/file_contexts.homedirs.bin: line 1 error due to: Non-ASCII characters found Updating : selinux-policy-targeted-3.13.1-224.fc26.noarch 54/156 /bin/su is affected as well: % su Password: /etc/selinux/mls/contexts/files/file_contexts.bin: line 1 error due to: Non-ASCII characters found /etc/selinux/mls/contexts/files/file_contexts.homedirs.bin: line 1 error due to: Non-ASCII characters found Reverting selinux-policy and selinux-policy-mls to 3.13.1-222 clears up the error messages. The problem appears to be in the preinstall scriptlet: if [ -e /etc/selinux/mls/.policy.sha512 ]; then POLICY_FILE=`ls /etc/selinux/mls/policy/policy.* | sort | head -1` sha512=`sha512sum $POLICY_FILE | cut -d ' ' -f 1`; checksha512=`cat /etc/selinux/mls/.policy.sha512`; if [ "$sha512" == "$checksha512" ] ; then rm /etc/selinux/mls/.rebuild; fi; So we look at the .policy.sha512 from the previous release - and then we compute the sha512 of the *current* policy, which is still the *previous* version because we're in preinstall, not postinstall. So of course they match, so we nuke .rebuild and then the postinstall doesn't run semodule. What *should* happen: the pre-install saves the sha512 file in a .pre, and then hash the policy and compare in the postinstall....
