Can't load the overlay over flatpak Steam #5951

Open carlocastoldi opened 1 year ago

carlocastoldi commented 1 year ago

The issue

Flatpak does not allow to punch a hole in the sandbox for some directories such as /lib, /lib32, /usr. I tried to copy the required libraries in Steam flatpak's directory in order to load the overlay:

cp /usr/lib32/libGL.so.1.7.0 /home/$USER/.var/app/com.valvesoftware.Steam/.local/share/Steam/linux32
cp /usr/lib/mumble/libmumbleoverlay.x86.so /home/$USER/.var/app/com.valvesoftware.Steam/.local/share/Steam/linux32
cd /home/$USER/.var/app/com.valvesoftware.Steam/.local/share/Steam/linux32
ln -s libGL.so.1.7.0 libGL.so.1
ln -s libGL.so.1 libGL.so

I then proceeded by setting the game launch options to: LD_PRELOAD=/home/user/.local/share/Steam/linux32/libmumbleoverlay.x86.so:/home/user/.local/share/Steam/linux32/libGL.so %command%

However, the game (TF2) still does not show the overlay if launched through flatpak Steam.

Any idea of how I can set the flatpak correctly in order to be able to access the right (system) libraries so that I can have the overlay?

Krzmbrzl commented 1 year ago

@davidebeatrici any ideas?

davidebeatrici commented 1 year ago

Could you pass the MUMBLE_OVERLAY_DEBUG environment variable and check the output again, please?

carlocastoldi commented 1 year ago

I always forget, sorry. Here it is: mumble-overlay-flatpak.log

I see many MumbleOverlay: connect() failure /run/user/1000/MumbleOverlayPipe :[]

davidebeatrici commented 1 year ago

The usual problem: "sandbox" containers generally allow the bare minimum required in order for the application to work.

In this case the overlay library cannot access the socket that is created by Mumble, see https://docs.flatpak.org/en/latest/sandbox-permissions.html.

carlocastoldi commented 1 year ago

Do you know any way to punch a whole in the sandbox to allow system libraries to access a flatpak application?

currently steam has the following socket permissions:

[Context]
shared=network;ipc;
sockets=x11;wayland;pulseaudio;
devices=all;
davidebeatrici commented 1 year ago

filesystem=xdg-run/MumbleOverlayPipe I think.

carlocastoldi commented 1 year ago

That improved the logs, yes! But it is still not completely fixed: mumble-overlay-flatpak.log

I see a couple of MumbleOverlay: Failed to map memory. Could be relevant: they are not present in un-sendboxed execution

github-actions[bot] commented 1 year ago

As there has been no activity on this issue for a couple of days, we assume that your issue has been fixed in the meantime. Should this not be the case, please let us know.

If no further activity happens, this issue will be closed within 3 days.

carlocastoldi commented 1 year ago

it is not fixed!

Krzmbrzl commented 1 year ago

As this is a flatpak-specific issue, it should be reported to https://github.com/flathub/info.mumble.Mumble/issues

carlocastoldi commented 1 year ago

well this is about using native Mumble with flatpak'd Steam. It should not be reported to flatpak Mumble.

But I guess that if atm @davidebeatrici can't figure it out from the log file, no one else can. In that case this issue remains unsolved

Krzmbrzl commented 1 year ago

Then I misunderstood - but it remains a flatpak issue as it does not appear in unsandboxed environment.

carlocastoldi commented 1 year ago

I am trying to investigate on my own, then. I'm no C++/Qt developer, tho. Could you please tell me how to properly compile /src/tests/OverlayTest.cpp?

Krzmbrzl commented 1 year ago

If it is not built when using -Dtests=ON, I don't know. Perhaps @davidebeatrici knows?

davidebeatrici commented 1 year ago

Tests that don't have their own subdirectory have never been enabled. I personally never ran them.

Krzmbrzl commented 1 year ago

Okay, me neither :shrug:

carlocastoldi commented 1 year ago

I discovered that --device=all most probably does not include --device=shm. I assumed that it did and lost a day investigating on the issue :sweat_smile: Setting --device=shm to Steam's flatpak solved it completely!

On the plus side: I managed to build OverlayTest.cpp. I can share it but it's quite unorthodox: I couldn't manage to link mumble/SharedMemory.cpp and mumble/SharedMemory_unix.cpp, so I ended up doing a bad trick to make it work regardless

carlocastoldi commented 1 year ago

also: flatpak steam must be run after mumble. Don't know why: I thought it was a matter of preloading the overlay library when running the game...

Krzmbrzl commented 1 year ago

Great to hear you got it working :+1:

carlocastoldi commented 1 year ago

Thanks!

However, do you have any idea why Mumble must be running before flatpak steam is launched? It otherwise cannot connect (error: connection refused) to the local socket.

regarding Mumble having to be launched before flatpak Steam: it seems like Steam can't see the connect to the local socket if Mumble is run after Steam (error: connection refused).

If I go into flatpak's bash (flatpak run --command=bash com.valvesoftware.Steam) I notice that permissions on the Mumble's local socket change:

Mumble after flatpak Steam. Only read permissions. Date/time is wrong.

Mumble after flatpak Steam. Works as intended. Full permissions. Date/time is correct.


#### Mumble _restarted_ with flapak Steam running. Doesn't work. Full permissions.
The number of hard links of the socket changes to `0`. I think this means that the socket was deleted. Date/time is wrong: indeed confirming that it points to the "old" socket and does not update the old one.

* flatpak bash:
```bash

Discord

on a similar note Discord, which also communicates with Steam through a local socket, doesn't have this problem. They create links to sockets that do not (yet) exist if Discord isn't running:

https://github.com/flathub/com.valvesoftware.Steam/pull/273 is relevant. I'll try to make flatpak Steam maintainers aware of it. If they propose to do something similar to what they did to Discord, I'll come back to this issue

Krzmbrzl commented 1 year ago

I have no idea about any of this, unfortunately :shrug:

carlocastoldi commented 1 year ago

I managed to make it work regardless if Mumble was running before Steam or not. In order to make it work for everyone we should put all named pipes and local socket inside a subdir in $XDG_RUNTIME_DIR/. Can I proceed working on a PR for that?

Krzmbrzl commented 1 year ago

@davidebeatrici ?

carlocastoldi commented 1 year ago

Can we also change default runtime path, if $XDG_RUNTIME_DIR is not set, to /run/user/<UID>?

(can we re-open this issue, btw?)

carlocastoldi commented 1 year ago

I actually noticed that this was discussed in #1660, but @mkrautz asked to use $XDG_RUNTIME_DIR/MumbleSocket and $XDG_RUNTIME_DIR/MumbleOverlayPipe instead of creating a sub-directory $XDG_RUNTIME_DIR/mumble. Don't know why, tho.
