Description of problem: Queuegraph doesn't have SELinux contexts set correctly, and therefore when SELinux is active, queuegraph won't work through apache. Version-Release number of selected component (if applicable): queuegraph-1.1-6.el6.noarch queuegraph-selinux-1.1-6.el6.noarch How reproducible: Steps to Reproduce: 1. Enable SELinux on CentOS 6 2. Surf to http://host/queuegraph 3. Actual results: 500 Internal Server Error Expected results: The normal queuegraph pages Additional info: Please also see bz566513 for a similar problem with mailgraph (also on EL6) Here is the error in /var/log/httpd/error_log: [Thu Aug 18 02:09:04 2011] [error] [client 10.0.0.135] (13)Permission denied: exec of '/usr/share/queuegraph/queuegraph.cgi' failed [Thu Aug 18 02:09:04 2011] [error] [client 10.0.0.135] Premature end of script headers: queuegraph.cgi Here is the error in /var/log/audit/audit.log: type=AVC msg=audit(1313626144.344:719): avc: denied { execute } for pid=3908 comm="httpd" name="queuegraph.cgi" dev=sda2 ino=43519713 scontext=unconfined_u:system_r:httpd_t:s0 tcontext=system_u:object_r:usr_t:s0 tclass=file type=SYSCALL msg=audit(1313626144.344:719): arch=c000003e syscall=59 success=no exit=-13 a0=7f994b151168 a1=7f994b14cec8 a2=7f994b14cee0 a3=7fffa58254a0 items=0 ppid=2974 pid=3908 auid=500 uid=48 gid=48 euid=48 suid=48 fsuid=48 egid=48 sgid=48 fsgid=48 tty=(none) ses=11 comm="httpd" exe="/usr/sbin/httpd" subj=unconfined_u:system_r:httpd_t:s0 key=(null)
I noticed the fix in bz243302 and I tried them on queuegraph: $ sudo chcon -t httpd_sys_script_exec_t /usr/share/queuegraph/queuegraph.cgi $ sudo chcon -R -t httpd_sys_script_ra_t /var/cache/queuegraph $ sudo chcon -R -t httpd_sys_script_ra_t /var/lib/queuegraph Now queuegraph shows (empty) graphs. It did not work for mailgraph bz566513 but that is maybe because this is a fresh install and postfix has not been configured yet. Please let me know if you need more information or would like me to test a new policy.
This message is a notice that Fedora 15 is now at end of life. Fedora has stopped maintaining and issuing updates for Fedora 15. It is Fedora's policy to close all bug reports from releases that are no longer maintained. At this time, all open bugs with a Fedora 'version' of '15' have been closed as WONTFIX. (Please note: Our normal process is to give advanced warning of this occurring, but we forgot to do that. A thousand apologies.) Package Maintainer: If you wish for this bug to remain open because you plan to fix it in a currently maintained version, feel free to reopen this bug and simply change the 'version' to a later Fedora version. Bug Reporter: Thank you for reporting this issue and we are sorry that we were unable to fix it before Fedora 15 reached 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 to click on "Clone This Bug" (top right of this page) and open it against that version of Fedora. 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. The process we are following is described here: http://fedoraproject.org/wiki/BugZappers/HouseKeeping
If this error still occurs, please reopen the ticket.
