[PATCH] quick selinux support for tracefs

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Yongqin Liu <yongqin.liu@xxxxxxxxxx>

Here is just the quick fix for tracefs with selinux.
just add tracefs to the list of whitelisted filesystem
types in selinux_is_sblabel_mnt(), but the right fix would be to
generalize this logic as described in the last item on the todo list,
https://bitbucket.org/seandroid/wiki/wiki/ToDo
