Description Bastien Nocera 2008-03-17 06:24:43 EDT
(Using the current CVS bluez-utils, with the PS3 remote control patches applied,
hcid uses uinput to feed events from the remote into the input layer)


SELinux is preventing bluetoothd-serv (bluetooth_t) "read write" to uinput

Detailed Description:

SELinux denied access requested by bluetoothd-serv. It is not expected that this
access is required by bluetoothd-serv 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:

Sometimes labeling problems can cause SELinux denials. You could try to restore
the default system file context for uinput,

restorecon -v 'uinput'

If this does not work, there is currently no automatic way to allow this access.
Instead, you can generate a local policy module to allow this access - see FAQ
(http://fedora.redhat.com/docs/selinux-faq-fc5/#id2961385) Or you can disable
SELinux protection altogether. Disabling SELinux protection is not recommended.
Please file a bug report (http://bugzilla.redhat.com/bugzilla/enter_bug.cgi)
against this package.
