Description Rudolf Kastl 2009-11-21 19:03:22 UTC

Zusammenfassung:

SELinux is preventing /usr/bin/python "connect" access.

Detaillierte Beschreibung:

[system-config-k hat einen toleranten Typ (kdumpgui_t). Dieser Zugriff wurde
nicht verweigert.]

SELinux denied access requested by system-config-k. It is not expected that this
access is required by system-config-k 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.

Zugriff erlauben:

You can generate a local policy module to allow this access - see FAQ
(http://fedora.redhat.com/docs/selinux-faq-fc5/#id2961385) Please file a bug
report.

Comment 1 Daniel Walsh 2009-11-23 14:53:38 UTC

You can add these rules for now using

# grep avc /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp

Fixed in selinux-policy-3.6.32-48.fc12.noarch
