Description JAB_au 2009-11-27 06:39:30 UTC
Summary:

SELinux is preventing /sbin/consoletype access to a leaked
/root/savap-install.log file descriptor.

Detailed Description:

[consoletype has a permissive type (consoletype_t). This access was not denied.]

SELinux denied access requested by the consoletype command. It looks like this
is either a leaked descriptor or consoletype output was redirected to a file it
is not allowed to access. Leaks usually can be ignored since SELinux is just
closing the leak and reporting the error. The application does not use the
descriptor, so it will run properly. If this is a redirection, you will not get
output in the /root/savap-install.log. You should generate a bugzilla on
selinux-policy, and it will get routed to the appropriate package. You can
safely ignore this avc.

Allowing Access:

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

This looks like a simple redirection of output to a file in /root.

Or the tool you are using is leaking a file descriptor.  What tool is doing this?

I got this when installing Symantec AntiVirus for Linux. Symantec probably need to look at their RPM packages a bit.

You can add these rules for now using

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