(In reply to Niki Guldbrand from comment #3) I also needed a similar policy module, BUT with these additionals: require { type ntpd_t; type ntpd_log_t; class dir remove_name; class file { read write unlink link }; } #============= ntpd_t ============== allow ntpd_t ntpd_log_t:dir remove_name; allow ntpd_t ntpd_log_t:file { read write unlink link }; > This is the current policy module I'm using right now to fix this. > > module net.guldbrand.ipa_ntpd 1.0; > > require { > type ntpd_t; > type ntpd_log_t; > class dir remove_name; > class file { unlink link }; > } > > #============= ntpd_t ============== > > allow ntpd_t ntpd_log_t:dir remove_name; > allow ntpd_t ntpd_log_t:file unlink; > allow ntpd_t ntpd_log_t:file link;
The selinux-policy-3.12.1-59.fc19 testing update seems to fix all my issues with this issue. No need for a "local" policy module.
selinux-policy-3.12.1-59.fc19 has been pushed to the Fedora 19 stable repository. If problems still persist, please make note of it in this bug report.
