However, on some object classes permission is revalidated on every object use (like files and file descriptors). So, even though a process has a file descriptor to a file it previously had access top open, if the permissions change to that file type the next read or write operation will fail which essentially revokes access to it. This should be the case on a file types, fds, sockets, ipc (except shared memory). -- This message was distributed to subscribers of the selinux mailing list.

Further, SELinux checks access to descriptors upon execve when the security context changes, and when descriptors are received via local IPC. This controls propagation of the access rights among security contexts. -- Stephen Smalley National Security Agency -- This message was distributed to subscribers of the selinux mailing list.
