This request was evaluated by Red Hat Product Management for inclusion in a Red Hat Enterprise Linux release. Product Management has requested further review of this request by Red Hat Engineering, for potential inclusion in a Red Hat Enterprise Linux release for currently deployed products. This request is not yet committed for inclusion in a release. Well this does not relate with log and probably should be opened as a new bug. The AVC was generated by the same TC and is a part of comment#1. Based on the recorded time I would say that the AVC is related to the scenario described in comment#0. MIlos, could you re-test it with a local policy type openvpn_tmp_t; files_tmp_file(openvpn_tmp_t) manage_files_pattern(openvpn_t, openvpn_tmp_t, openvpn_tmp_t) files_tmp_filetrans(openvpn_t, openvpn_tmp_t, file) When the local policy module is loaded, the AVC does not appear any more and the daemon starts as expected. Since the problem described in this bug report should be resolved in a recent advisory, it has been closed with a resolution of ERRATA. For information on the advisory, and where to find the updated files, follow the link below. If the solution does not work for you, open a new bug report. http://rhn.redhat.com/errata/RHBA-2013-1312.html |
Description of problem: openvpn fails to start since it cannot read/write to /var/log/openvpn. Version-Release number of selected component (if applicable): selinux-policy-2.4.6-342.el5 selinux-policy-targeted-2.4.6-342.el5 selinux-policy-minimum-2.4.6-342.el5 selinux-policy-devel-2.4.6-342.el5 selinux-policy-strict-2.4.6-342.el5 selinux-policy-mls-2.4.6-342.el5 openvpn-2.3.1-1.el5 How reproducible: always. Steps to Reproduce: 1. update to openvpn 2.3.1 2. try to start it 3. profit. Actual results: openvpn is unable to read/write /var/log/openvpn and won't start. Expected results: openvpn is able to read/write /var/log/openvpn and starts.
