All so got this related on: Subject: [SELinux AVC Alert] SELinux is preventing /usr/sbin/ntpd from remove_name access on the directory /var/log/ntpstats/peerstats SELinux is preventing /usr/sbin/ntpd from remove_name access on the directory /var/log/ntpstats/peerstats. ***** Plugin catchall (100. confidence) suggests *************************** If you believe that ntpd should be allowed remove_name access on the peerstats directory by default. Then you should report this as a bug. You can generate a local policy module to allow this access.

Update it with: # su -c 'yum update --enablerepo=updates-testing selinux-policy-3.12.1-59.fc19' as soon as you are able to. Please go to the following url: https://admin.fedoraproject.org/updates/FEDORA-2013-12373/selinux-policy-3.12.1-59.fc19 then log in and leave karma (feedback). (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. |
