Description Matěj Cepl 2010-06-30 12:39:32 UTC 
Souhrn:

SELinux is preventing /sbin/ebtables "search" access .

Podrobný popis:

[ebtables je v toleratním režimu (virtd_t). Přístup byl povolen.]

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

Povolení přístupu:

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

Comment 4 Miroslav Grepl 2010-07-01 16:55:52 UTC 
This is different issue.

Matej,
could you try to execute

chcon -t iptables_exec_t /sbin/ebtables
Comment 5 Miroslav Grepl 2010-07-08 07:56:25 UTC 
Virt folks,
are you seeing any problems relating to ebtables and libvirt? Could you test it?
Comment 6 Daniel Walsh 2010-07-12 15:28:08 UTC 
Miroslav this is the label we have in Rawhide, so lets make it this in RHEL6.
Comment 7 Miroslav Grepl 2010-07-12 15:38:43 UTC 
Yes, I added it to Rawhide and will update F13/RHEL6 policy.
Comment 10 Miroslav Grepl 2010-07-14 14:28:18 UTC
