From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Rustdesk looks good on the outside, but if you look inside, it has a really bad codebase and has done some sketchy stuff in the past.

Last year, it installed custom root certificates as trusted on windows, which is a huge security risk: https://github.com/rustdesk/rustdesk/discussions/6444

On linux systems, it forced its own autostart with no option to disable this behavior: https://github.com/rustdesk/rustdesk/issues/4863

In the past, when it didn’t have Wayland support yet, it edited your GDM config and just disabled wayland: https://github.com/rustdesk/rustdesk/blob/1.1.9/src/platform/linux.rs#L411-L422

Furthermore, the code quality is really bad. 90% of the linux platform-dependant code is just executing shell commands and parsing their output, while the same could be achieved in a safe way with proper rust builtins: https://github.com/rustdesk/rustdesk/blob/master/src/platform/linux.rs

While I agree that Rustdesk works pretty flawlessly, the codebase and the behavior of the developers made me distrust the software and I don’t recommend using it.

Wth is that, that is the most anti-idiomatic code I have ever seen

https://github.com/rustdesk/rustdesk/blob/master/src%2Fplatform%2Flinux.rs#L176

pub fn get_cursor() -> ResultType<Option<u64>> {
    let mut res = None;
    DISPLAY.with(|conn| {
        if let Ok(d) = conn.try_borrow_mut() {
            if !d.is_null() {
                unsafe {
                    let img = XFixesGetCursorImage(*d);
                    if !img.is_null() {
                        res = Some((*img).cursor_serial as u64);
                        XFree(img as _);
                    }
                }
            }
        }
    });
    Ok(res)
}

I'm not an expert but this seems wrong.

Yep, I'm not a Rust expert either, but this is pretty cursed. The comments on this post have some more examples of bad rustdesk code: https://lobste.rs/s/njfvjb/rustdesk_with_tailscale_on_arch_linux
