this needs to be reported against selinux-policy of course. changed that. policy version test against is selinux-policy-targeted-3.12.1-75.fc20.noarch. Any chance to update to the latest policy and re-test it and attach AVC msgs if it does not work. Thank you. # rpm -q selinux-policy-targeted
selinux-policy-targeted-3.12.1-90.fc20.noarch
# ausearch -m AVC -ts today

It would seem this would be best handled via a transition on execution of journalctl. So the only way these logs would be viewable would be with journalctl. We don't want to allow a loose permissioned log file to be read by a confined user. a689b59da27ef127338fe9342a926220c9f8d4b9 and e4f229150289137efe78d644daf2fcf8a4b331ec Adds journalctl policy to git. This message is a reminder that Fedora 20 is nearing its end of life. Approximately 4 (four) weeks from now Fedora will stop maintaining and issuing updates for Fedora 20. It is Fedora's policy to close all bug reports from releases that are no longer maintained. At that time this bug will be closed as EOL if it remains open with a Fedora 'version' of '20'. Package Maintainer: If you wish for this bug to remain open because you plan to fix it in a currently maintained version, simply change the 'version' to a later Fedora version. Thank you for reporting this issue and we are sorry that we were not able to fix it before Fedora 20 is end of life. If you would still like to see this bug fixed and are able to reproduce it against a later version of Fedora, you are encouraged change the 'version' to a later Fedora version prior this bug is closed as described in the policy above. Although we aim to fix as many bugs as possible during every release's lifetime, sometimes those efforts are overtaken by events. Often a more recent Fedora release includes newer upstream software that fixes bugs or makes them obsolete. Fedora 20 changed to end-of-life (EOL) status on 2015-06-23. Fedora 20 is no longer maintained, which means that it will not receive any further security or bug fix updates. As a result we are closing this bug. If you can reproduce this bug against a currently maintained version of Fedora please feel free to reopen this bug against that version. If you are unable to reopen this bug, please file a new report against the current release. If you experience problems, please add a comment to this bug. Thank you for reporting this bug and we are sorry it could not be fixed. |
Description of problem: Confined SELinux users are not able to view user logs, while unconfined users can view the logs: $ journalctl Hint: You are currently not seeing messages from other users and the system. Users in the groups 'adm', 'systemd-journal', 'wheel' can see all messages. Pass -q to turn off this notice. No journal files were opened due to insufficient permissions. $ id -Z staff_u:staff_r:staff_t:s0 vs. $ journalctl -- Logs begin at Thu 2013-10-10 22:02:54 CEST, end at Wed 2013-10-23 19:59:56 CEST. -- Oct 10 22:02:54 fedora.virt.tuxgeek.de systemd[1011]: Failed to open private bus connection: Failed to connect to socket /run/user/1000 Oct 10 22:02:54 fedora.virt.tuxgeek.de systemd[1011]: Mounted /sys/kernel/config.
