Subject[PATCH] Reduce SELinux check on KDSKBENT/SENT ioctls
From
Date
This patch against 2.6.0 reduces the full capability check in the
SELinux module for the KDSKBENT/SENT ioctls to only check the
corresponding SELinux permission, avoiding a change to the Linux
permissions model for these operations. Please apply, or let me know if
you'd like this resubmitted later. Thanks.
