ports VS dxvk-native

I think OpenBSD comes the closest to what you want with its two easy to use syscalls that provide syscall filtering and restricting access to paths:

https://man.openbsd.org/pledge.2

https://man.openbsd.org/unveil.2

A few random examples:

https://github.com/tmux/tmux/blob/c8494dff7b6b9a996866edaf8c...

https://github.com/openbsd/ports/blob/master/www/mozilla-fir...

https://github.com/openbsd/ports/blob/master/www/mozilla-fir...

To get the best isolation you need to patch the source — the application needs to go through initial setup and then drop privileges to the absolute possible minimum. But it's easy to make custom wrappers for third-party applications — the above profiles taken from the OpenBSD ports tree are the proof.

Have you checked the no-ip port: https://github.com/openbsd/ports/blob/master/net/no-ip/pkg/noip2.rc

> https://github.com/openbsd/ports/commit/bf33ea5f3ff390d8cde3...

Now, this is surprising. I randomly clicked on that link and I immediately see that the code and the patch has a bug. It only checks the first 8 characters:

    -      if (gr != NULL && strncmp(gr->gr_name, "operator", 8) == 0)

Some people are working around this by using obsdfreqd, some by patching sys/kern/sched_bsd.c (change if (hw_power) to if (0 && hw_power)), some by simply setting to a lower speed (sysctl hw.perfpolicy=manual and hw.setperf=99 might be enough as this disables turbo mode found on some CPUs).

You could also look into a port that has a hard dependency on openssl like: https://github.com/openbsd/ports/tree/master/security/sslscan

For me it's the ease of management and good documentation.

For example, during 6.8 to 6.9 upgrade, there was a major postgresql upgrade.

It is mentioned in the doc https://www.openbsd.org/faq/upgrade69.html (see Special packages at the bottom).

You're redirected to the package README with special instructions on how to setup and upgrade: https://github.com/openbsd/ports/blob/master/databases/postg...

Et voilà, everything is explained.

On debian, if I am not careful, I'll do an upgrade and risk breaking something during a db migration (I'm looking at you MySQL upgrades...).

Godot engine gamecontroller support. This is limited and incomplete, but it's a start. A huge number of indie games made with Godot are released every week; most of which work at least partially with an XBox {360,One} controller. You can follow This Week in Godot if you're interested.

> OpenBSD has handled this case for some years. I do not know if there was any breakage or fallout from this.

The other thing about OpenBSD is that when they make a change to their OS, they also go through to make sure all the (third-party) ports/packages:

* https://cvsweb.openbsd.org/ports/

* https://github.com/openbsd/ports

do not break. So they're create patches for the software and and submit them upstream.

DXVK 2.0 has upstreamed the dxvk-native code, meaning the game runs using native Linux libraries but uses DX11 with DXVK. This is mostly done because the ancient OpenGL linux-native renderer was rather bad.

what works best is games supporting dxvk-native: https://github.com/Joshua-Ashton/dxvk-native

There is DXVK native which doesn't require wine.

https://github.com/Joshua-Ashton/dxvk-native

There are also Dxvk native for porting game to Linux. Which is used by valve to port it's game to Linux.(replacing togl)

I disagree, but I get the frustration. It's just that I've been playing CS:GO for almost a decade, and while I think the game is neglected by Valve in general, it's way a worse scenario on Linux. For instance, Vulkan support (via dxvk-native) was added back in December last year, and it's not been updated ever since, so you get way worse stuttering when compared to OpenGL (which is actually a DirectX 9 to OpenGL translation layer, called toGL, which has its own set of bugs and issues); Plus, you can't change screen resolution when using Vulkan. I get some occasional little stutters on Windows as well, but the whole CS:GO experience is honestly just way worse on Linux, unfortunately.

DXVK-Native and the game Perimeter. Perimeter is the one game I know of that's opensource and that uses DXVK-Native. I got it to run, but there was no support for any audio, making this pretty unexciting. This is still being worked on upstream, so maybe a DXVK-native port later and a port of perimeter will happen then...

You never mentioned that requirement, but here you go: https://github.com/Joshua-Ashton/dxvk-native

DirectX isn't an option on linux/mac anyway, it's just launch or safe mode. (Note to any SCS developers if they're lurking around here... please implement the DX pipeline into the linux build so we can use DXVK-Native, it's much faster than OGL!)
