Robert Watson 0142affc77 Introduce accessor functions mac_label_get() and mac_label_set() to replace ... LABEL_TO_SLOT() macro used by policy modules to query and set label data in struct label. Instead of using a union, store an intptr_t, simplifying the API. Update policies: in most cases this required only small tweaks to current wrapper macros. In two cases, a single wrapper macros had to be split into separate get and set macros. Move struct label definition from _label.h to mac_internal.h and remove _label.h. With this change, policies may now treat struct label * as opaque, allowing us to change the layout of struct label without breaking the policy module ABI. For example, we could make the maximum number of policies with labels modifiable at boot-time rather than just at compile-time. Obtained from: TrustedBSD Project		2007-02-06 14:19:25 +00:00
