Description of problem:

This seems to be a reintroduction of an old fixed bug from FC6 (245693).

SELinux is preventing /usr/sbin/nmbd (nmbd_t) "rename" to log.nmbd (samba_log_t).

In addition the log rotation fails in /var/log/samba by strange log files like
-rw-r--r-- 1 root root  695880 2007-09-25 14:21 log.nmbd
-rw-r--r-- 1 root root       0 2007-09-24 04:12 log.nmbd.1
-rw-r--r-- 1 root root 1350222 2007-09-24 04:12 log.nmbd.1.1
-rw-r--r-- 1 root root       0 2007-09-23 04:12 log.nmbd.1.1.1
-rw-r--r-- 1 root root 5181678 2007-09-23 04:12 log.nmbd.1.1.1.1

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

selinux-policy-targeted-2.6.4-42.fc7
selinux-policy-2.6.4-42.fc7
libselinux-devel-2.0.14-4.fc7
samba-client-3.0.26a-0.fc7
samba-3.0.26a-0.fc7
system-config-samba-1.2.52-1.fc7
samba-common-3.0.26a-0.fc7

How reproducible:

Very reproducible. The [avc: denied { rename } for comm="nmbd"...] messages
appear periodically and at least once daily.

Steps to Reproduce:
1. Install all of the components in the FC7 OS on i686 or AMD64 (installed as
i686 architecture).
2. Apply all updates effective September 24, 2007.
3. Setup SAMBA as follows:
        # setsebool -P samba_domain_controller on
        # setsebool -P samba_enable_home_dirs on
4. Enable Services: smbd, nmd
5. Add Passwords: See man pdbedit
        # pdbedit -a -u auser


Actual results:
Samba works fine, but it is prevented from rotating logs by selinux policy.

Expected results:
No more [avc: denied { rename } for comm="nmbd"...] messages.

Summary
    SELinux is preventing /usr/sbin/nmbd (nmbd_t) "rename" to log.nmbd
    (samba_log_t).

Detailed Description
    SELinux denied access requested by /usr/sbin/nmbd. It is not expected that
    this access is required by /usr/sbin/nmbd 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 log.nmbd, restorecon -v log.nmbd
    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 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
    http://bugzilla.redhat.com/bugzilla/enter_bug.cgi against this package.
