Description abdeslam 2009-11-18 13:15:31 UTC

SELinux is preventing /bin/bash "getattr" access on /bin/uname.

Detaillierte Beschreibung:

SELinux denied access requested by sh. It is not expected that this access is
required by sh 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

You can add these rules for now using

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