21 hourskern: os: Add I/O tap frameworkIan Moffett
The I/O tap framework provides a way to bypass the typical device filesystem interface for applications where more direct access would be beneficial. Signed-off-by: Ian Moffett <ian@osmora.org>
22 hourskern: os: Support up to 8 max namespacesIan Moffett
Signed-off-by: Ian Moffett <ian@osmora.org>

Signed-off-by: Ian Moffett <ian@osmora.org>
29 hoursos: vnode: Add refcounts to vnodesIan Moffett
Keep track of how many referencing are on a vnode so one isn't freed early while another object is still using it. Signed-off-by: Ian Moffett <ian@osmora.org>

13 dayskern: mac: Make mac_map() return ssize_tIan Moffett
The map callback within the MAC ops returns ssize_t, therefore the mac_map() wrapper should return the same Signed-off-by: Ian Moffett <ian@osmora.org>
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>
