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.

Kernel, libc: Implement spawn()
...
This function is a Luna alternative to fork() and exec().
Why? Simply because I can't figure out for the life of me how to implement a working fork().
So meanwhile, we have spawn() as a replacement. exec() still exists, though.

Replace the rand() which reads from /dev/random with a Mersenne PRNG.
...
Much better now.
Also, it is seeded by reading from /dev/random at startup. Not sure if that's the best idea, but we'll see.

2022-10-15 13:21:22 +02:00

Kernel, libc: Remove the rand() system call
...
That's why we now have a VFS and a /dev pseudo-filesystem. To provide that kind of things.
Remember, everything is a file!!
The new way to ask the kernel for random numbers is to read from /dev/random.
