Bug 624644

Summary:

SELinux is preventing /usr/bin/gcm-apply "read" access to device 003.

Detailed Description:

[gcm-apply has a permissive type (xdm_t). This access was not denied.]

SELinux has denied gcm-apply "read" access to device 003. 003 is mislabeled,
this device has the default label of the /dev directory, which should not
happen. All Character and/or Block Devices should have a label. You can attempt
to change the label of the file using restorecon -v '003'. If this device
remains labeled device_t, then this is a bug in SELinux policy. Please file a bg
report. If you look at the other similar devices labels, ls -lZ /dev/SIMILAR,
and find a type that would work for 003, you can use chcon -t SIMILAR_TYPE
'003', If this fixes the problem, you can make this permanent by executing
semanage fcontext -a -t SIMILAR_TYPE '003' If the restorecon changes the
context, this indicates that the application that created the device, created it
without using SELinux APIs. If you can figure out which application created the
device, please file a bug report against this application.

Allowing Access:

Attempt restorecon -v '003' or chcon -t SIMILAR_TYPE '003'
