NetLabel: make netlbl_lsm_secattr struct easier/quicker to understand
The existing netlbl_lsm_secattr struct required the LSM to check all of the fields to determine if any security attributes were present resulting in a lot of work in the common case of no attributes. This patch adds a 'flags' field which is used to indicate which attributes are present in the structure; this should allow the LSM to do a quick comparison to determine if the structure holds any security attributes. Example: if (netlbl_lsm_secattr->flags) /* security attributes present */ else /* NO security attributes present */ Signed-off-by: Paul Moore <paul.moore@hp.com> Signed-off-by: James Morris <jmorris@namei.org>
