KEYS: special dot prefixed keyring name bug fix
Dot prefixed keyring names are supposed to be reserved for the
kernel, but add_key() calls key_get_type_from_user(), which
incorrectly verifies the 'type' field, not the 'description' field.
This patch verifies the 'description' field isn't dot prefixed,
when creating a new keyring, and removes the dot prefix test in
key_get_type_from_user().
Changelog v6:
- whitespace and other cleanup
Changelog v5:
- Only prevent userspace from creating a dot prefixed keyring, not
regular keys - Dmitry
