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.

Wayland running GUI program as another user (self.linux)

I use https://github.com/slingamn/namespaced-openvpn to have a isolated namespace and VPN connection

On X, these two steps would allow me to run a GUI program in the protected namespace. So I could have .e.g an IDE configuration for my main user/personal projects, and another entirely different instance of the same IDE for work because they use different users

sudo xhost '+si:localuser:user'
sudo ip netns exec protected sudo -u user -i

On Wayland, although the protected shell is created fine, GUI programs don't start. E.g fgor Dolphin

error: XDG_RUNTIME_DIR is invalid or not set in the environment.
Failed to create wl_display (No such file or directory)

I've tried to preserve the env without success:


sudo -E ip netns exec protected sudo -u user -i

It seems that I access to the wayland socket is a must for this to work

This discussion has a nuke option - giving 777 access to the dir where the wayland socket is, and another less permissive approach adding the users to a group and giving access to a new location where the wayland socket is created

https://stackoverflow.com/questions/41736528/linux-wayland-display-multiple-user

Is this second approach secure? If not, which other steps could I take to achieve what I did in X?
