Description rramesh_babu 2010-01-31 13:23:18 UTC 
Summary:

SELinux is preventing /sbin/mount.fuse.ifuse "getattr" access on
/var/run/usbmuxd.

Detailed Description:

SELinux denied access requested by mount.fuse.ifus. It is not expected that this
access is required by mount.fuse.ifus 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 2010-02-01 20:29:50 UTC 
Miroslav we need a policy for usbmuxd.

Does the mount succeed?

If you put the machine in permissive mode, what other avcs do you get?

Comment 3 Miroslav Grepl 2010-02-02 15:16:43 UTC 
I have just created the same policy for F12 :^). I am going to add it to the default policy.
Comment 4 Daniel Walsh 2010-02-02 16:13:29 UTC 
Ok if you find any differences send them to me.
