Kernel, libc: Add a getdents() system call
...
This is meant to be a low-level interface to implement dirent.h on top of.
2022-10-23 14:03:46 +02:00

Kernel: Update libk's string.h
2022-10-22 19:06:06 +02:00

Kernel: Add a pstat() system call
...
Not part of C or POSIX, but since there is no procfs right now, I thought it would be nice to have an interface to query process information.
It works like this: you pass the process ID and a pointer to a struct pstat (can be null).
If the process ID is -1, the kernel picks the process with the highest PID.
Then, if the pointer to a pstat struct is not null, the kernel fills it in with the process's information, and returns the process's PID.

This is a huge step forward!! bc actually runs now, without echo or backspace, but it runs!!

UserMemory: do not map refs into kernel memory
...
This is bad design. But it fails if mapped, since something overwrites KernelHeap.

KernelHeap: Add more debug logging

b035795eb3
Kernel: Move errno.h and (k)assert.h out of the main include directory
...
This is mostly so IDEs don't pick them up instead of the userspace headers :)
2022-10-19 17:41:23 +02:00
48d4a5910a
Kernel: Add a few convenience functions to manipulate userland memory
2022-10-19 17:13:16 +02:00

Kernel, libc: Implement waitpid()

FIXME: exec() is now doing weird page table stuff. But at least it works, no panics :)
2022-10-18 21:30:52 +02:00
52d391507d
Kernel: Rename the getpid() syscall to getprocid()
...
Now, we have one single system call to fetch all sorts of identifiers:
PID, PPID, UID, GID; EUID, EGID, and more...

Kernel, libc: Remove spawn()
...
Now, fork() and exec() are both implemented. More POSIX-y, thus spawn can be removed.

Kernel, libc: Implement fork()
...
This time for real.
Also, add a new per-user-task virtual address allocator (UserHeap), so that mmap'ed pages are in user range and can be copied.
