Subject: [PATCH] KEYS: Reinstate EPERM for a key type name beginning with a
 '.'

commit 54e2c2c1a9d6cbb270b0999a38545fa9a69bee43 upstream.

Reinstate the generation of EPERM for a key type name beginning with a '.' in
a userspace call.  Types whose name begins with a '.' are internal only.

The test was removed by:

	commit a4e3b8d79a5c6d40f4a9703abf7fe3abcc6c3b8d

	Subject: KEYS: special dot prefixed keyring name bug fix

I think we want to keep the restriction on type name so that userspace can't
add keys of a special internal type.

Note that removal of the test causes several of the tests in the keyutils
testsuite to fail.
