SELinux-entries regarding /tmp/vbox.X - directories

[Moritz Isselstein]

SELinux creates for every file in the /tmp/vbox.0/... /tmp/vbox.1/... directories and subdirectories an event similar to the following:

SElinux-entry (example):

Zusammenfassung
SELinux is preventing tmpwatch (tmpreaper_t) "getattr" to /tmp/vbox.1/r0drv/linux/thread-r0drv-linux.c (usr_t).

Detaillierte Beschreibung
SELinux denied access requested by tmpwatch. It is not expected that this access is required by tmpwatch 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.

Zugriff erlauben
Sometimes labeling problems can cause SELinux denials. You could try to restore the default system file context for /tmp/vbox.1/r0drv/linux/thread-r0drv-linux.c, restorecon -v '/tmp/vbox.1/r0drv/linux/thread-r0drv-linux.c' 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 Or you can disable SELinux protection altogether. Disabling SELinux protection is not recommended. Please file a bug report against this package.
