Usually you have a usb stick which has a file system on it which supports labels, but no one put labels onto it. Confined apps like colord are not allowed to look at file_t, since the kernel has no idea what kind of content is there. But the bug here is with colord trying to look at every file system that gets mounted on the system. We have an open bug with it to stop doing this. If the admin knows what kind of content is on the stick, it is up to him to label it appropriatly, or mount it with the appropriate label. For example if it contained apache content you would either run chcon system_u:object_r:httpd_sys_content_t:s0 /run/media/ Or mount it using the context option mount -o context=system_u:object_r:httpd_sys_content_t:s0 /dev/sd100 /run/media -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.15 (GNU/Linux) Comment: Using GnuPG with Thunderbird - http://www.enigmail.net/ iEYEARECAAYFAlJueccACgkQrlYvE4MpobMehQCg0kBbUrcGZAuBqJJocod+3zcc TUAAoN4YquWG8RgI6kmKcg20iovIGvxy =3KmV -----END PGP SIGNATURE----- -- selinux mailing list selinux@xxxxxxxxxxxxxxxxxxxxxxx https://admin.fedoraproject.org/mailman/listinfo/selinux
