Kernel, libc: Rename gettid() to getpid() and move it to unistd.h
2022-10-17 20:08:44 +02:00
1e96a45f33
Change 'tid' to 'PID' in init.c
...
I think tasks can be considered programs now. So, gettid() is equal to getpid().
In fact, it should be renamed. And moved to unistd.h. Soon.

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.

Devices: Add a new RandomDevice :)
...
This new device uses the seeded Mersenne PRNG we use in the kernel.
This device is not meant for regular userspace use, but more for userspace to seed their own PRNGs from.
If the DeviceFS is mounted at /dev, this device can be found at /dev/random.

It (almost) works now
...
The only thing doing weird stuff is exec(), so that's commented out and throws ENOSYS right now.
But we have two user tasks running in parallel, isolated from each other!
2022-10-14 16:46:00 +02:00
531b2848ac
init: Execute /bin/sym instead of /sys/config
...
We have now proven that exec() does fail and return to userspace when a file is not a valid executable.
We can now go back to executing a normal program.
