There is no "leak" when the secctx is recorded in the audit log - it is 
supposed to be there, if present (and retrievable). As for exposing the 
(internal) numerical representation of the secctx - this was discussed 
previously and the approach you are suggesting was dropped. To quote 
Eric on this very issue "[It] exports the internal secid to userspace. 
These are dynamic, can change on lsm changes, and have no meaning in 
userspace. We should instead be sending lsm contexts to userspace instead.".
