Description of problem: selinux refuses access to /var/log/BackupPC/UserEmailInfo.pl by perl. Version-Release number of selected component (if applicable): selinux-policy-3.3.1-78.fc9.noarch How reproducible: Always. Steps to Reproduce: 1. View BackupPC pages via a browser. Actual results: setroubleshoot pops up a warning. Expected results: No warning? Additional info: Here's the alert from setroubleshoot: Summary: SELinux is preventing the perl5.10.0 from using potentially mislabeled files /var/log/BackupPC/UserEmailInfo.pl (var_log_t). Detailed Description: SELinux has denied the perl5.10.0 access to potentially mislabeled files /var/log/BackupPC/UserEmailInfo.pl. This means that SELinux will not allow httpd to use these files. Many third party apps install html files in directories that SELinux policy cannot predict. These directories have to be labeled with a file context which httpd can access. Allowing Access: If you want to change the file context of /var/log/BackupPC/UserEmailInfo.pl so that the httpd daemon can access it, you need to execute it using chcon -t httpd_sys_content_t '/var/log/BackupPC/UserEmailInfo.pl'. You can look at the httpd_selinux man page for additional information.

What package owns this file? rpm -qf /var/log/BackupPC/UserEmailInfo.pl Why is it in such a stange place? If you copied this file to /etc/BackupPC where BackupPC seems to store its perl code or somewhere under /usr/share/BackupPC it would also work. If you chcon -t /var/log/BackupPC/UserEmailInfo.pl it should fix the problem temporarily. But this file should be moved.
According to rpm, the file is unowned. UserEmailInfo.pl is kind of anomalous, in that it is both a log file generated by BackupPC *and* a syntactically correct block of Perl, which I assume is intended to be imported and executed by some other part of BackupPC using 'eval', 'use', or 'require'. According to the BackupPC docs (http://backuppc.sourceforge.net/faq/BackupPC.html) UserEmailInfo.pl is "A summary of what email was last sent to each user, and when the last email was sent." Moving it to /usr/share/BackupPC would be wrong because it's a log file. And regardless, simply moving it to /etc/BackupPC or /usr/share/BackupPC without changing BackupPC wouldn't work, since it wouldn't know to look in those places.
You can add an exception for it to SELinux policy: # semanage fcontext -a -t httpd_log_t /var/log/BackupPC/UserEmailInfo.pl And it should fix your problem.
I'm currently working on a new policy for BackupPC-3.1.0. As BackupPC comes with its own SELinux policy, I think it could be reassigned. For now, new policy is not ready at all, you could temporary put the correct selinux context with chcon, using httpd_log_log as proposed by Josef, or httpd_sys_content_t ; one should does the trick.
This message is a reminder that Fedora 9 is nearing its end of life. Approximately 30 (thirty) days from now Fedora will stop maintaining and issuing updates for Fedora 9. 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 WONTFIX if it remains open with a Fedora 'version' of '9'. 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 prior to Fedora 9's end of life. Bug Reporter: Thank you for reporting this issue and we are sorry that we may not be able to fix it before Fedora 9 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 please change the 'version' of this bug to the applicable version. If you are unable to change the version, please add a comment here and someone will do it for you. 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
Fedora 9 changed to end-of-life (EOL) status on 2009-07-10. Fedora 9 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. Thank you for reporting this bug and we are sorry it could not be fixed.
