(In reply to Miroslav Grepl from comment #8) > Jakub, > does it really want to execute? No, it does not. abrt-dump-journal-xorg tests whether the '/usr/bin/Xorg' path is has executable mode bit: https://github.com/abrt/abrt/blob/master/src/plugins/xorg-utils.c#L106 <snip> if (access("/usr/bin/Xorg", X_OK) == 0) crash_info->exe = xstrdup("/usr/bin/Xorg"); else crash_info->exe = xstrdup("/usr/bin/X"); </snip> The tool tries to guess the path because Xorg back-traces found in syslog does not have any information about which program generated them and ABRT needs the path to get rpm package details and so on. Ok it makes sense. Thank you. This package has changed ownership in the Fedora Package Database. Reassigning to the new owner of this component. This message is a reminder that Fedora 23 is nearing its end of life. Approximately 4 (four) weeks from now Fedora will stop maintaining and issuing updates for Fedora 23. It is Fedora's policy to close all bug reports from releases that are no longer maintained.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 '23'. 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 23 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 23 changed to end-of-life (EOL) status on 2016-12-20. Fedora 23 is no longer maintained, which means that it will not receive any further security or bug fix updates.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: SELinux is preventing abrt-dump-journ from 'execute' accesses on the file /usr/bin/Xorg. ***** Plugin catchall (100. confidence) suggests ************************** If you believe that abrt-dump-journ should be allowed execute access on the Xorg file by default. Then you should report this as a bug. You can generate a local policy module to allow this access. Do allow this access for now by executing: # grep abrt-dump-journ /var/log/audit/audit.log | audit2allow -M mypol # semodule -i mypol.pp Additional Information: Source Context system_u:system_r:abrt_dump_oops_t:s0 Target Context system_u:object_r:xserver_exec_t:s0 Target Objects /usr/bin/Xorg [ file ] Source abrt-dump-journ Source Path abrt-dump-journ Port <Unknown> Host (removed) Source RPM Packages Target RPM Packages xorg-x11-server-Xorg-1.18.0-2.fc23.x86_64 Policy RPM selinux-policy-3.13.1-155.fc23.noarch Selinux Enabled True Policy Type targeted Enforcing Mode Enforcing Host Name (removed) Platform Linux (removed) 4.2.6-300.fc23.x86_64 #1 SMP Tue Nov 10 19:32:21 UTC 2015 x86_64 x86_64 Alert Count 10 First Seen 2015-11-25 09:58:20 EET Last Seen 2015-11-25 09:58:29 EET Local ID e7578b4b-513c-449d-b12e-f3871ad7d3bd Raw Audit Messages type=AVC msg=audit(1448438309.300:1476): avc: denied { execute } for pid=17370 comm="abrt-dump-journ" name="Xorg" dev="dm-2" ino=794321 scontext=system_u:system_r:abrt_dump_oops_t:s0 tcontext=system_u:object_r:xserver_exec_t:s0 tclass=file permissive=0 Hash: abrt-dump-journ,abrt_dump_oops_t,xserver_exec_t,file,execute Version-Release number of selected component: selinux-policy-3.13.1-155.fc23.noarch Additional info: reporter: libreport-2.6.3 hashmarkername: setroubleshoot kernel: 4.2.6-300.fc23.x86_64 type: libreport
