Summary:
SELinux is preventing webalizer (webalizer_t) "read" to inotify (inotifyfs_t).
Detailed Description:
SELinux denied access requested by webalizer. It is not expected that this access is required by webalizer and this access may signal an intrusion attempt. It is also possible that the specific version or configuration of the application is causing it to require additional access.
Allowing Access:
Sometimes labeling problems can cause SELinux denials. You could try to restore the default system file context for inotify,
restorecon -v 'inotify'
If this does not work, there is currently no automatic way to allow this access. Instead, you can generate a local policy module to allow this access - see FAQ Or you can disable SELinux protection altogether. Disabling SELinux protection is not recommended. Please file a bug report against this package.

Fixed in selinux-policy-3.5.13-21.fc11.noarch This bug appears to have been reported against 'rawhide' during the Fedora 10 development cycle. Changing version to '10'. More information and reason for this action is here: http://fedoraproject.org/wiki/BugZappers/HouseKeeping This message is a reminder that Fedora 10 is nearing its end of life. Approximately 30 (thirty) days from now Fedora will stop maintaining and issuing updates for Fedora 10. It is Fedora's policy to close all bug reports from releases that are no longer maintained.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 '10'. 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 10'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 10 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 10 changed to end-of-life (EOL) status on 2009-12-17. Fedora 10 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. |
Some of the log messages are in German... sorry about this, but I think it's sufficient to describe the issue. I get the following message once a day in /var/log/messages: Oct 28 04:02:01 centaur setroubleshoot: SELinux hindert webalizer (webalizer_t) "read" am Zugriff auf inotify (inotifyfs_t).

The directory it tries to access is /proc/sys/fs/inotify.
