Can't load the overlay over flatpak Steam #5951

carlocastoldi · 2022-11-06T12:26:38Z

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?

@davidebeatrici any ideas?

davidebeatrici · 2022-11-06T20:35:11Z

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

carlocastoldi · 2022-11-06T21:41:10Z

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

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

davidebeatrici · 2022-11-06T23:25:20Z

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 · 2022-11-06T23:53:40Z

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 · 2022-11-07T00:07:00Z

filesystem=xdg-run/MumbleOverlayPipe I think.

carlocastoldi · 2022-11-07T00:24:01Z

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

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 · 2022-11-11T09:43:49Z

it is not fixed!

Krzmbrzl · 2022-11-11T10:40:07Z

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

carlocastoldi · 2022-11-11T10:56:42Z

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 · 2022-11-11T11:10:50Z

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

carlocastoldi · 2022-11-12T00:17:37Z

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 · 2022-11-12T07:04:41Z

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

davidebeatrici · 2022-11-12T08:25:16Z

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

Krzmbrzl · 2022-11-12T14:26:29Z

Okay, me neither 🤷

carlocastoldi · 2022-11-12T20:03:30Z

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 😅
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 · 2022-11-12T20:08:22Z

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 · 2022-11-13T09:23:46Z

Great to hear you got it working 👍

carlocastoldi · 2022-11-13T11:24:07Z

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.

flatpak bash:

[📦 com.valvesoftware.Steam ~]$ ls -l /run/user/1000/MumbleOverlayPipe 
-r--r--r-- 1 carlo carlo 0 13 nov 10.24 /run/user/1000/MumbleOverlayPipe

host bash:

❯ ls -l /run/user/1000/MumbleOverlayPipe
srwxrwxrwx 1 carlo carlo 0 13 nov 11.58 /run/user/1000/MumbleOverlayPipe

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

flatpak bash:

[📦 com.valvesoftware.Steam ~]$ ls -l /run/user/1000/MumbleOverlayPipe 
srwxrwxrwx 1 carlo carlo 0 13 nov 12.00 /run/user/1000/MumbleOverlayPipe

host bash:

❯ ls -l /run/user/1000/MumbleOverlayPipe
srwxrwxrwx 1 carlo carlo 0 13 nov 12.00 /run/user/1000/MumbleOverlayPipe

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:

[📦 com.valvesoftware.Steam ~]$ ls -l /run/user/1000/MumbleOverlayPipe 
srwxrwxrwx 0 carlo carlo 0 13 nov 12.00 /run/user/1000/MumbleOverlayPipe

hosh bash:

❯ ls -l /run/user/1000/MumbleOverlayPipe
srwxrwxrwx 1 carlo carlo 0 13 nov 12.10 /run/user/1000/MumbleOverlayPipe

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:

flathub/com.valvesoftware.Steam#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 · 2022-11-13T15:51:57Z

I have no idea about any of this, unfortunately 🤷

carlocastoldi · 2022-11-13T18:15:09Z

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 · 2022-11-13T19:34:46Z

@davidebeatrici ?

carlocastoldi · 2022-11-13T19:37:24Z

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 · 2022-11-13T19:56:04Z

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.

Moving MumbleSocket and MumbleOverlayPipe to a dedicated subdirectory keeps the runtime directory clean and allows flatpak applications to use the overlay by giving access only to Mumble's subdirectory. It also moves the default directory to /run/user/$UID/mumble/ when $XDG_RUNTIME_DIR is not set. Fixes mumble-voip#5951
