7 months ago Following bugreport is a duplicate of this one. That other bugreport contains a workaround (uninstalling eid-mw), but I would like this bug to be solved, as I would like to be able to use eid-mw and steam on the same PC at the same time....

That's... terrible.
The package appears to be ancient and would not be accepted in its current state were it added today.
It should not rely on any globally-installed shared library; that breaks just about every design decision in Nix.
I can't help you with fixing that but doing it the Nix way would solve the issue.
I do wonder how this global library path that nothing on NixOS should ever use for anything ends up being picked up by steam though; that appears to be the actionable bug here.

7 months ago @Atemu: thanks for your feedback. Indeed, could you maybe edit the Steam code so that it does not try to use libbeidpkcs11.so during startup? It would be best if Steam also ignores libpcsclite.so.1 (see logs above). Both libraries are used for accessing Belgian electronic ID cards.

7 months ago We'll first have to figure out how it even gets discovered by steam because that path is never explicitly passed to it AFAICT.
What's your LD_LIBRARY_PATH in the system and inside steam-run?

I do not understand how Steam discovers this path then.
A quick hack could be to use an extraBwrapArg to mount a tmpfs at /run/current-system/sw/lib/. Could you try that?

7 months ago I only started using NixOS in June 2023. So compared to you, I am pretty much a novice :-) I am not sure how to perform that hack.... I think that reproducible builds - one of the many strengths of NixOS - should mean that the bugs should be reproducible as well, on (almost) any PC. If you install the steam package from nixpkgs, and then enable following configuration, you should be able to reproduce my issue on your PC as well.

}The problem is that I don't have your hardware or state or ability to use eid-mw in any way.

7 months ago I configured the following:

dedicatedServer.openFirewall = true; # Open ports in the firewall for Source Dedicated Server
package = pkgs.steam.override { extraBwrapArgs = [ "--tmpfs /run/current-system/sw/lib/" ]; };
};When I now try to launch steam, I get:

eid-mw maintainers:
@bfortz @chvp

If one of the maintainers above lives in Belgium and has an eid card reader, it would be great if that person tried to recreate this bug on their own PC. But to be honest, you don't even need an eid card reader, nor an eid card; you just need to install eid-mw as system package and install steam too..... Then steam will crashloop...
chvp
commented
7 months ago I use both steam and eid-mw, and do not encounter this issue. One important difference though is that I use Firefox, so I don't do the nssdb step. Presumably steam's web helper is chromium based, which would explain how it picks up eid: through the nssdb.
MarkRijckenberg
commented
7 months ago That leaves 2 options:
1) fix the code behind the command "eid-nssdb add" so that the library libbeidpkcs11.so is never picked up by steam.
2) adapt the instructions in https://search.nixos.org/packages?channel=unstable&show=eid-mw&from=0&size=50&sort=relevance&type=packages&query=eid-mw
and instruct people to only use firefox and never use eid-nssdb add. But then: why include eid-nssdb in the first place?
The instructions state:
"To use eIDs in NSS-compatible browsers like Chrom{e,ium} or Firefox, each user must first execute: ~$ eid-nssdb add (Running the script once as root with the –system option enables eID support for all users, but will not work when using Chrom{e,ium}!) Before uninstalling this package, it is a very good idea to run ~$ eid-nssdb [–system] remove and remove all ~/.pki and/or /etc/pki directories no longer needed."
If the instructions tell me to run eid-nssdb add and this causes a crashloop of steam, there clearly is a problem
chvp
commented
7 months ago Maybe we should first verify that nssdb is the problem here? Can you follow the uninstall instructions and then check that steam starts up correctly?

7 months ago I tested on both my laptop and desktop PC.
Running "eid-nssdb remove" solved the issue on both PCs, but that means support for chromium and brave browsers is removed.
I would prefer option 1 (fixing the eid-nssdb code), so we don't depend on using just one webbrowser (firefox)
@chvp : can you run "eid-nssdb add" and then launch steam to confirm that this bug is reproducible?
chvp

7 months ago Running eid-nssdb add does break steam for me. I'll investigate further on the weekend or next week, don't really have the time right now.
MarkRijckenberg

7 months ago OK, thanks for confirming the bug.
MarkRijckenberg
commented
7 months ago Can one of the eid-mw maintainers maybe look into this tomorrow or Sunday?
chvp
commented
7 months ago Sorry, forgot about this. I did some more investigating. It seems that eid-mw uses C++ exceptions to handle when things are not found during configuration lookups. What I can't figure out though, is why the exceptions are not getting caught (at least, that's what the stack trace leads me to believe).
MarkRijckenberg
commented
7 months ago I am no coding expert, especially in C++. But maybe it will help to analyze the following 11 code segments in the eid-mw source code that mention libbeidpkcs11.so? This file should get sandboxed/isolated somehow, so it is not picked up anymore by applications not used for web browsing (like steamwebhelper)
https://github.com/search?q=repo%3AFedict%2Feid-mw+libbeidpkcs11.so&type=code
The coredump shows "./steamwebhelper --no-sandbox" So steamwebhelper is not running sandboxed. So I guess it is up to eid-mw to sandbox libbeidpkcs11.so. Of course, all of this could be obvious to you :-)
chvp
commented
7 months ago As far as I could find, there's no way to configure NSS so that libbeidpkcs11.so gets picked up by e.g. chrome but not by steamwebhelper. The sandbox is not really relevant here, NSS runs outside of the sandbox anyway.

@Atemu @eclairevoyant @jonringer @K900 @mkg20001
Question for the steam package maintainers: is it possible to create a package override for steam - programmed using the nix language - to force steam and steamwebhelper to skip/ignore any library file starting with libbeidpkcs11* ? I know it sounds like an ugly hack, but then it would solve my issue without having to adapt code in steamwebhelper/steam/eid-mw/eid-nssdb
Atemu
commented
7 months ago Only thing I could think of would be to bind-mount /dev/null atop of the nix store path of that so.
The code of eid-mw/eid-nssdb needs to be changed anyways.

6 months ago I have written following ugly hack and added it as package to environment.systemPackages
I would prefer to have a more elegant solution, but beggars can't be choosers....
Apparently steamwebhelper crashloops by reading "library=/run/current-system/sw/lib/libbeidpkcs11.so" from ~/.pki/nssdb/pkcs11.txt
steamwebhelper should not be reading from ~/.pki/nssdb/ !
After deleting ~/.pki/nssdb/pkcs11.txt , steam launches fine.

steam-runtime-heavy.tar.xz and steam-runtime-sniper.tar.xz contain libnss3 (network security service libraries)
Why do the steam-runtimes contain libnss3? libnss3 is useful for web browsers like chromium, but not for gaming clients. I suspect that the libnss3 libraries contained in steam-runtime-heavy.tar.xz and steam-runtime-sniper.tar.xz are responsible for searching for libraries in ~/.pki/nssdb/pkcs11.txt The steam developers should really take a good hard look at the steam-runtime code and rip out any code that is ONLY useful for a webbrowser, but NOT useful for gaming clients like steam.

Steam has a web browser, using Chromium Embedded Framework (CEF)

commented
6 months ago Yes, I know that Steam has a web browser component, but do steam-runtime-heavy and SteamLinuxRuntime_sniper NEED libnss3 too? I am not saying to remove the web browser (chromium) component. I am asking to remove the web browser functionalities NOT needed for a gaming client. Doing so would have 2 potential benefits:

6 months ago Following documentation confirms that the libnss3 library reads from ~/.pki/nssdb/pkcs11.txt
https://discourse.ubuntu.com/t/network-security-services-nss/35168
So as long as the steam client remains bundled with libnss3 (and related support for PKCS security modules), this bug will probably persist.

6 months ago @MarkRijckenberg Perhaps we could use libredirect to make either of these look in the nix store instead of the .pki directory in the home dir.
MarkRijckenberg
commented
6 months ago Using libredirect would be a workaround for a security function (PKCS) that should not be supported here in the first place. At least, that is my assumption. And nobody has contradicted me on this yet. If I am wrong in this assumption, please let me know!
I looked at https://github.com/NixOS/nixpkgs/blob/master/pkgs/games/steam/steam.nix Version is still stuck at version 1.0.0.74 which is ancient. I wonder why the version number has not been bumped up to version 1.0.0.79 yet. (see https://repo.steampowered.com/steam/archive/stable/?C=M&O=A )
I would suggest 2 steps: 1) attempt to update the steam source code to upgrade from 1.0.0.74 to 1.0.0.79 2) at the same time: replace libnss3 with openssl in order to keep supporting TLS/SSL connections, but dropping support for PKCS security modules. The eid-mw package already depends on openssl. I checked that using nix-tree, because nix-tree gives a real-time view of the package dependencies on my system.
I support first principles thinking. The best component is no component. Reducing complexity increases the security of the application, reduces software bloat and also follows the principle of least privileges. Only give an application the minimum features it needs to function, nothing more....

6 months ago 1) This is just the Steam bootstrapper, it has basically nothing to do with the actual client, it just sets up the environment, then downloads the latest client from Valve 2) No one can do that but Valve

6 months ago @K900 Thanks for your feedback. Does it mean I should close this issue here and reopen it on https://github.com/ValveSoftware/steam-for-linux/issues ? Or are there Valve employees working here in https://github.com/NixOS/nixpkgs/issues ?

6 months ago The issue should probably be reported to Valve, specifically to make them aware that Steam will load mismatched libraries through this specific escape hatch.

6 months ago @chvp : could you please implement the solution mentioned here?
https://github.com/ValveSoftware/steam-runtime/issues/667
This means:
Simply replacing
libfile="/run/current-system/sw/lib/libbeidpkcs11.so"
with
libfile="/run/current-system/sw/lib/opensc-pkcs11.so"
in the eid-nssdb script
Apparently there is a bug in /run/current-system/sw/lib/libbeidpkcs11.so that causes the crashloop of steam, nothing else. Replacing this library with opensc-pkcs11.so circumvents the whole issue, without having to remove PKCS support in libnss3.
This solution means there is no need to adapt the nixpkgs documentation regarding the use of "eid-nssdb add"
MarkRijckenberg
commented
6 months ago I have solved the crashlooping issue by performing a complete reinstall of the steam client on NixOS unstable.
I ran rm -rf ~/.local/share/Steam Then reran steam to force a new install. No more crashlooping of steam, even when libbeidpkcs11.so is loaded via eid-nssdb add
Describe the bug
steamwebhelper goes into a launch-crash-launch loop forever. This occurs with both nvidia and nouveau drivers. steam never gets to the startup screen. Sometimes it gets to the login screen and when I type my username and password, the login screen crashes and steam simply opens a new login screen....
libbeidpkcs11.so (part of eid-mw ) causes crash of steamwebhelper on NixOS 24.05.20240323.44d0940 (Uakari) x86_64
See also https://github.com/NixOS/nixpkgs/blob/2735b578a86297de1f030f07a4763669b7ddbeb1/pkgs/tools/security/eid-mw/eid-nssdb.in#L6
Steps To Reproduce
Expected behavior
steam package and eid-mw package should be able to co-exist on the same NixOS 24.05 system. These are totally unrelated packages. steam should be able to launch fine, even if libbeidpkcs11.so is installed via eid-mw package
steamwebhelper should skip/ignore libbeidpkcs11.so which is used for Belgian eid cards. libbeidpkcs11.so has nothing to do with steam.
Additional context
crashdump of steamwebhelper shows following error:
0x000075bd642dcd40 n/a (libbeidpkcs11.so + 0x22d40)
See more details in logs below, including output of "coredumpctl dump 7511"
Running "eid-nssdb remove" solves crashloop issue, but this should not be necessary. steamwebhelper (part of steam) is trying to do something with libbeidpkcs11.so , but should skip it instead....
Here is my system configuration:
And here are the logs while using the nouveau drivers:
