2025-09-23kern: security: Add initial support for MACIan Moffett
This commit introduces initial support for mandatory access control. As one may recall, L5 follows "everything is memory". In order to interact with a resource, a process must request it from the kernel in the form of a (sometimes) syncable memory buffer. Each resource as well as processes have an access level, if a process attempts to request a resource with a higher access level than it, the request is rejected by the kernel. However, if a process has a greater than or equal access level as a resource, the request can be granted. Signed-off-by: Ian Moffett <ian@osmora.org>
