Bug 543412

Summary:

SELinux is preventing logrotate (logrotate_t) "read" to / (user_home_t).

Detailed Description:

SELinux denied access requested by logrotate. / may be a mislabeled. / default
SELinux type is root_t, but its current type is user_home_t. Changing this file
back to the default type, may fix your problem.

File contexts can be assigned to a file in the following ways.

  * Files created in a directory receive the file context of the parent
    directory by default.
  * The SELinux policy might override the default label inherited from the
    parent directory by specifying a process running in context A which creates
    a file in a directory labeled B will instead create the file with label C.
    An example of this would be the dhcp client running with the dhclient_t type
    and creates a file in the directory /etc. This file would normally receive
    the etc_t type due to parental inheritance but instead the file is labeled
    with the net_conf_t type because the SELinux policy specifies this.
  * Users can change the file context on a file using tools such as chcon, or
    restorecon.

This file could have been mislabeled either by user error, or if an normally
confined application was run under the wrong domain.

However, this might also indicate a bug in SELinux because the file should not
have been labeled with this type.

If you believe this is a bug, please file a bug report
(http://bugzilla.redhat.com/bugzilla/enter_bug.cgi) against this package.

Allowing Access:

You can restore the default system context to this file by executing the
restorecon command. restorecon '/', if this file is a directory, you can
recursively restore using restorecon -R '/'.

Fix Command:

restorecon '/'
