Description Ivan Makfinsky 2008-11-11 09:28:56 EST
Description of problem:
Selinux is preventing logrotate from accessing log files in /var/log/ and as a result logrotate reports are never generated.

Version-Release number of selected component (if applicable):

How reproducible:
Every day, several times a day.

Steps to Reproduce:
1. Install logrotate. Install selinux-policy.
2. Hibernate/Suspend laptop.
3. Wake up laptop.
Actual results:
Selinux error message - 

SELinux is preventing logrotate (logrotate_t) "getattr" to
/var/log/pm-suspend.log (hald_log_t).

Detailed Description:

SELinux denied access requested by logrotate. It is not expected that this
access is required by logrotate 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 /var/log/pm-suspend.log,

restorecon -v '/var/log/pm-suspend.log'

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
(http://fedora.redhat.com/docs/selinux-faq-fc5/#id2961385) Or you can disable
SELinux protection altogether. Disabling SELinux protection is not recommended.
Please file a bug report (http://bugzilla.redhat.com/bugzilla/enter_bug.cgi)
against this package.

Comment 1 Daniel Novotny 2008-11-20 05:07:34 EST
what is the SElinux context of /var/log/pm-suspend.log ? ( ls -Z )

did you try the restorecons command? ( restorecons -v /var/log/pm-suspend.log )
Comment 2 Daniel Novotny 2009-02-25 08:32:21 EST
seems to be working OK now with newer selinux-policy.
if not, feel free to reopen the bug
