Description Knut-Håvard Aksnes 2007-06-04 19:57:15 UTC
Description of problem:

The complete message from setroubleshoot follows:

Summary
    SELinux is preventing genhomedircon (semanage_t) "write" to site-packages
    (lib_t).

Detailed Description
    SELinux denied access requested by genhomedircon. It is not expected that
    this access is required by genhomedircon 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 site-packages, restorecon -v
    site-packages 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.

How reproducible:

Don't know, the bug selinux bug report pops up after logging in everytime for
me. I only use the fedora and livna repositoies at the time being. (Livna for
Nvidia and audio/video)

Comment 1 Daniel Walsh 2007-06-04 20:01:46 UTC
This is strange.   genhomedircon should not be trying to write to a lib_t
directory.  This looks like some python object is not precreated and semanage is
trying to create it.  You can tell sealert to ignore the avc message.  Just
click the filter.
