30 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>

2 dayskern: syscall: Add SYS_mount syscallIan Moffett
This commit introduces the system call for mounting filesystems. As of now, only the fstype and target params are supported Signed-off-by: Ian Moffett <ian@osmora.org>

Signed-off-by: Ian Moffett <ian@osmora.org>
8 dayskern: Add initial pirho compiler sourcesIan Moffett
The pirho compiler is a ring-0 compiler used to compile core parts of the kernel during updates and installs from the initramfs. Signed-off-by: Ian Moffett <ian@osmora.org>
8 dayskern: vfs: Return vnode result in namei()Ian Moffett
Signed-off-by: Ian Moffett <ian@osmora.org>
9 dayskern: init: Initialize namespaces before modulesIan Moffett
Some modules rely on the object namespace to keep track of state for them. So we need to initialize the namespace before we initialize those modules Signed-off-by: Ian Moffett <ian@osmora.org>
9 dayskern: ns: Extract true object data from entryIan Moffett
Before, the lookup was only returning the object and not the data behind the object itself. Now we extra the data from the object that exists within the hashmap entry. Signed-off-by: Ian Moffett <ian@osmora.org>
9 dayskern: Add initial object namespace sourcesIan Moffett
Signed-off-by: Ian Moffett <ian@osmora.org>
10 dayskern: Add safe copyin() and copyout()Ian Moffett
Introduce new routines that make it safer to transfer data between userland and the kernel. Signed-off-by: Ian Moffett <ian@osmora.org>
10 daysbuild: Use clang during early stateIan Moffett
Use clang during early state until we configure our own cross compiler for L5 Signed-off-by: Ian Moffett <ian@osmora.org>

Signed-off-by: Ian Moffett <ian@osmora.org>
11 dayskern: namei: Fallback to path parse if lookup failIan Moffett
If the filesystem is marked to require image-like paths but the path could not be found, fallback to parsing it manually as perhaps it is somewhere else. Signed-off-by: Ian Moffett <ian@osmora.org>

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>

2025-09-21kern: Mount root filesystem in vfs_init()Ian Moffett
Signed-off-by: Ian Moffett <ian@osmora.org>
2025-09-21kern: vfs: Add support for image-like pathsIan Moffett
Typically filesystems are tree-like, however certain filesystems in the form of images have fixed paths baked into them. This optimizes handling so there isn't a need to unpack it into a rootfs/tmpfs Signed-off-by: Ian Moffett <ian@osmora.org>
2025-09-21kern: vfs: Add lookup by name helperIan Moffett
Signed-off-by: Ian Moffett <ian@osmora.org>
2025-09-21kern: Introduce clock device frameworkIan Moffett
This commit introduces a new framework we call "clkdev". It is used to keep track of the clock sources on the system and be able to fetch them later based on specific attributes. Signed-off-by: Ian Moffett <ian@osmora.org>
2025-09-20kern: Initialize ACPI before cpu_conf() callIan Moffett
Signed-off-by: Ian Moffett <ian@osmora.org>
2025-09-20kern: syscall: Add initial write(2) stubIan Moffett
Here we add a write(2) stub and add it to the UNIX syscall interface. We also move the UNIX syscall numbers into compat/unix/syscall.h Signed-off-by: Ian Moffett <ian@osmora.org>
2025-09-20kern: proc: Add address checking routineIan Moffett
Add routine to check if an address is valid within a process's address space. More work will need to be done with this but this introduces a great starting point Signed-off-by: Ian Moffett <ian@osmora.org>

Signed-off-by: Ian Moffett <ian@osmora.org>
2025-09-19kern: proc: Keep track of mapped areas with rangesIan Moffett
This commit adds a virtual memory range queue to the process descriptor in order to keep track of mapped pages and free their respective frames upon program exit. Signed-off-by: Ian Moffett <ian@osmora.org>

Signed-off-by: Ian Moffett <ian@osmora.org>
2025-09-19kern: vfs: Add namei() prototype functionIan Moffett
Introduce a namei() prototype function to build upon when implementing core namei() logic. The prototype simply implemenets the path parsing and mimicks a UNIX-like (shell) namei output. Signed-off-by: Ian Moffett <ian@osmora.org>
2025-09-19kern: vfs: Add mountpoint lookup helperIan Moffett
Add helper function to lookup mountpoints such as '/' Signed-off-by: Ian Moffett <ian@osmora.org>
