Description laurelai 2010-04-15 12:32:22 UTC 
Summary:

SELinux is preventing /usr/bin/nautilus "setattr" access on fd.

Detailed Description:

[nautilus has a permissive type (unconfined_t). This access was not denied.]

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

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 1 laurelai 2010-04-15 12:34:15 UTC 
I was starting a virtual machine and at the same time updates started to install, I don't know if that is relevant or not.
Comment 2 Daniel Walsh 2010-04-15 14:54:18 UTC 
This looks like something stupid nautilus is doing.  Makes no sense, so I think we should dontaudit it.

Miroslav add

# Nautilus causes this avc
dontaudit unpriv_userdomain self:dir setattr;
