Description Edofin 2009-11-23 03:56:46 UTC
Summary:

SELinux is preventing /usr/bin/mono "ioctl" access on /dev/sdd1.

Detailed Description:

[SELinux is in permissive mode. This access was not denied.]

SELinux denied access requested by mono. It is not expected that this access is
required by mono 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://fedora.redhat.com/docs/selinux-faq-fc5/#id2961385) Please file a bug
report.

Comment 1 Daniel Walsh 2009-11-23 16:18:59 UTC
Does not seem like something podsleuth should be doing.  Do you have any idea what caused this?

Yes, that's the default behaviour of podsleuth:

To read the serial number and the property list it will use the
"sg_ll_inquiry" function from libsgutils to do an SCSI_INQUIRY for a couple of
pages (this will cause selinux errors for open, getattr and ioctl).

Please see for details BZ #533399.
