78d72c2f0c
Kernel, libc: Add a getdents() system call
...
This is meant to be a low-level interface to implement dirent.h on top of.

wrong type :)

libc: Rename pstname() to pstatname()
...
To avoid confusion with ptsname().
2022-10-22 14:30:41 +02:00
6ac57a2f5c
libc: Add support for pstat()
2022-10-22 14:26:42 +02:00

Kernel, libc: Add fstat()
2022-10-21 18:31:09 +02:00

libc: Move SYS_* constants to sys/syscall.h
2022-10-19 17:49:55 +02:00
671f2a2de3
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
01564cb905
libc: Adapt libc to getprocid() + add getppid()
2022-10-18 17:36:33 +02:00

Kernel, libc: Rename gettid() to getpid() and move it to unistd.h

Kernel, libc: Remove spawn()
...
Now, fork() and exec() are both implemented. More POSIX-y, thus spawn can be removed.
2022-10-17 19:55:01 +02:00
64f5078494
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.

libc: Add support for mkdir()
2022-10-16 17:37:29 +02:00

libc: Add Luna-specific limits
2022-10-15 14:31:55 +02:00

libc: Add support for the new clock() system call
2022-10-15 13:21:22 +02:00
3a9dddaa57
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.

225284a6ca
libc: Add support for mprotect()
2022-10-15 12:59:13 +02:00
1e86acd4c0
libc: Implement fcntl(F_DUPFD) and dup()
2022-10-15 11:16:34 +02:00
531afc3d6f
libc: Add support for the new exec() system call
...
execv() is a temporary wrapper that ignores the second parameter, while execve() and execvp() still error out.
2022-10-12 17:45:58 +02:00
928ade123c
libc: Add support for the new seek() system call
2022-10-12 15:32:09 +02:00
d3ac590e24
Kernel: Remove the sys_getversion() syscall
...
User programs can now acquire this information by reading /dev/version.

Kernel, libc, userspace: Implement file descriptors
...
Kernel: Implement a descriptor struct which stores the opened node and read offset, and give each task 8 of those.
Implement three syscalls: sys_read, sys_open and sys_close (sys_write still writes to the console instead of using a fd, for now)
Implement three new errors: ENOENT, EBADF and EMFILE.
libc: Implement the new errors, and the new syscalls in syscall().
Also fix _RETURN_WITH_ERRNO() to set errno correctly, which was making strerror() return null, thus crashing perror().
userspace: make init demonstrate the new file API.
2022-10-10 20:21:39 +02:00
028a1b1a3c
libc: Enable even more warnings
2022-10-07 18:19:06 +02:00

Add mmap and munmap syscalls, and thus, add malloc and free to libc!! (yet again, thanks to the wonderful liballoc)
2022-10-02 20:45:04 +02:00
8e6741ebd6
Rename SYS_version to SYS_getversion
2022-10-02 17:25:56 +02:00

Add a proper syscall() function to unistd.h
2022-10-02 17:02:15 +02:00

Syscalls return a value, right?
