Please describe your issue in as much detail as possible:

I was trying to use a development version of a vulkan debug tool called Crash Diagnostic Layer (https://github.com/LunarG/CrashDiagnosticLayer). When using local builds of this layer AND enabling with vkconfig I get std::bad_cast. This also happens when using the Vulkan-ValidationLayer.

Local builds of both of the above layers work correctly when enabled using the environment variables VK_INSTANCE_LAYERS and VK_LAYER_PATH.

That's roughly consistent with what I see locally with gdb, initially I was getting this exception inside std::regex but now it looks like it is std::iostream.

TTimo · 2024-09-25T19:01:02Z

Can you provide the libVkLayer_crash_diagnostic.so you reproduced this with? Assuming it's the same file (build_id starts with f3e49bb0643fc86bacbe9b443c8d027d[..]) `and has debug symbols. Then I can expand the backtrace a little.

TTimo · 2024-09-25T19:08:21Z

@smcv is our specialist for this kind of thing, but I'm not sure it's particularly good or intentional that the internal usage of std::regex in a Vulkan layer pulled from the host by pressure-vessel ends up calling into libengine.so code.

There's probably several problems at play here, one of them being our exposing of these symbols in libengine.so to begin with, but also the Vulkan layer may need to static link libstdc++) more aggressively.

First order of business is probably to chase broader reproduction and see if we see this happening on Ubuntu 22 or a non debian distro (Arch possibly since it's our primary dev environment).

smcv · 2024-09-25T19:38:10Z

I'm not sure it's particularly good or intentional that the internal usage of std::regex in a Vulkan layer pulled from the host by pressure-vessel ends up calling into libengine.so code

I think that's probably the root cause here. Is libengine.so statically linking parts of libstdc++ and accidentally or intentionally re-exporting them? If yes, it should avoid doing that: we cannot guarantee that its libstdc++ is completely compatible with anyone else's.

std::bad_cast

This sounds like some component is (quite reasonably!) complaining that the runtime type information for std::regex implementation A doesn't say it's an instance of std::regex implementation B.

smcv · 2024-09-25T19:40:05Z

One possible mitigation for this would be having Vulkan-Loader load its layers with RTLD_LOCAL if it doesn't already, and having the Source engine similarly load its internal libraries libengine.so, etc. with RTLD_LOCAL if it doesn't already.

The loader is using RTLD_LAZY | RTLD_LOCAL:
https://github.com/KhronosGroup/Vulkan-Loader/blob/31cfa022eff1061a1ec8b3f1cd17b5b709fa6fee/loader/vk_loader_platform.h#L388

jeremyg-lunarg · 2024-09-25T19:56:39Z

but also the Vulkan layer may need to static link libstdc++) more aggressively.

having the layer statically link against libstdc++ seems to avoid the problem:

     if(CMAKE_SYSTEM_NAME MATCHES "Linux")
+        target_link_libraries(crash_diagnostic PRIVATE  -static-libgcc -static-libstdc++)

smcv · 2024-09-26T11:51:53Z

having the layer statically link against libstdc++ seems to avoid the problem

Yeah, that's a useful workaround if you can arrange for it to happen on the host system. It would be better if we can avoid the Source2 engine triggering this problem from the engine end, but that's difficult to achieve (I have a couple of ideas which might potentially help there, I'll see what happens after testing them).

The fundamental problem here is that there are two copies of std::regex in action here: the one in the host system's libstdc++ as linked by the Vulkan layer, and the one in the libstdc++ that the game engine links statically. Because the game engine exports its copy of libstdc++, ELF library semantics say that it "interposes" in the place of the one in the shared libstdc++ - the same mechanism that is in use when you use something like libtcmalloc or libasan to replace malloc() with a more optimized or more debuggable substitute. I don't think the Source2 engine necessarily wants to interpose its statically linked libstdc++ symbols, but it's accidentally what happens.

smcv · 2024-09-26T11:53:44Z

The loader is using RTLD_LAZY | RTLD_LOCAL

That means the Vulkan layer can't cause the equivalent of this crash in Source2 engine code, but the Source2 engine can still cause this crash in Vulkan layer code. Using RTLD_LOCAL would only fully work if it was done symmetrically, "at both ends".

smcv · 2024-09-26T14:08:38Z

When using local builds of this layer AND enabling with vkconfig I get std::bad_cast. This also happens when using the Vulkan-ValidationLayer.

Local builds of both of the above layers work correctly when enabled using the environment variables VK_INSTANCE_LAYERS and VK_LAYER_PATH.

What does vkconfig actually do to get CS2 to load these layers?

I'm trying to keep my test systems relatively "ordinary" to make my testing as representative as possible of what will happen on end-user systems, so if possible I'd prefer not to install software from outside the official Arch and Ubuntu repositories that end users would not normally have, which includes the external Vulkan SDK packages.

smcv · 2024-09-26T14:21:01Z

OK, vkconfig is available in Arch (packaged in vulkan-extra-tools), so I can experiment with it without installing software from outside the distro.

It looks as though it arranges for extra layers to be loaded by writing out ~/.local/share/vulkan/implicit_layer.d/VkLayer_override.json as a temporary meta-layer that has the layer I requested as one of its component_layers, and then deleting that file when finished. I'll try to make an in-distro reproducer for this based on that information.

jeremyg-lunarg · 2024-09-26T14:51:56Z

Exactly right. Does the runtime do something special for layers set in the VK_INSTANCE_LAYERS environment variable? That works on my system when vkconfig doesn't. And at this point it is the only part of this issue that doesn't make sense to me.

smcv · 2024-09-26T15:27:28Z

Does the runtime do something special for layers set in the VK_INSTANCE_LAYERS environment variable?

No, the source code doesn't even mention it. At the moment we "capture" every implicit and explicit layer from the host system, together with its recursive dependencies, and let Vulkan-Loader worry about whether the layer is actually runtime-enabled or not.

We use the environment variables that are part of how layers are discovered, like VK_ADD_LAYER_PATH, but we currently ignore all environment variables that are only used for the decision to enable or not enable.

(We're actually thinking of changing that, to avoid disabled layers creating action-at-a-distance side-effects - but that isn't implemented yet.)

You've said that when the validation layer is activated via VK_INSTANCE_LAYERS, it works, but when it's activated by being listed in a meta-layer, it crashes? At the moment, the only reason I can think of for how that could happen is that the loading order in Vulkan-Loader could end up being different.

smcv · 2024-09-26T15:35:48Z

I tried to reproduce this on an up-to-date Ubuntu 24.04 Nvidia system with the distro's validation layer (version 1.3.275.0-1), by creating this:

$ cat ~/.local/share/vulkan/implicit_layer.d/SteamRuntimeIssue694.json 
{
    "file_format_version": "1.1.2",
    "layer": {
        "api_version": "1.3.250",
        "blacklisted_layers": [
        ],
        "component_layers": [
            "VK_LAYER_KHRONOS_validation"
        ],
        "description": "Reproducer for https://github.com/ValveSoftware/steam-runtime/issues/694",
        "disable_environment": {

        },
        "implementation_version": "1",
        "name": "STEAM_RUNTIME_ISSUE_694",
        "override_paths": [
            "/usr/share/vulkan/explicit_layer.d"
        ],
        "type": "GLOBAL"
    }
}

/proc/$(pgrep cs2 | tail -n1)/maps said that /run/host/usr/lib/x86_64-linux-gnu/libVkLayer_khronos_validation.so (which is the container's "view" of /usr/lib/x86_64-linux-gnu/libVkLayer_khronos_validation.so from the host system) was loaded, and my framerate was really bad, suggesting that the extra validation was indeed happening - but I couldn't reproduce the crash by loading CS2 and entering a training mission.

If you use a similar hand-written JSON file instead of vkconfig, does that reproduce the crash for you? Perhaps we can converge on a minimal reproducer by both working towards it from opposite directions?

jeremyg-lunarg · 2024-09-26T16:48:23Z

Good idea. I was able to reproduce with the following:

~/.local/share/vulkan/implicit_layer.d/bad_cast.json:

{
    "file_format_version": "1.1.2",
    "layer": {
        "api_version": "1.3.290",

        "override_paths": [

        ],
        "type": "GLOBAL"
    }

I think there's 2 key parts:

In the .json file, override_paths needs to point to the directory containing the locally built .so filie.
vk_layer_settings.txt is required to get into a code path that uses std::regex, when just using the env vars we get empty strings querying for those settings and skip the code that parses them using regex. So this explains why I couldn't repro with env vars before.

I created a simplified version of this situation to test various ideas against, and I found that in that project, I had to link the mockup Vulkan layer with -Wl,-Bsymbolic as well. (But perhaps your layers already do that.)

smcv · 2024-09-26T18:53:06Z

Aha, that's useful information. I couldn't reproduce this today, but I'll try again tomorrow armed with that additional knowledge.

Crash dumps:

Hopefully this is enough for an engine developer to at least confirm whether I reproduced the same crash? And maybe those steps help an engine developer to reproduce this.

On Arch + AMD + Mesa, I couldn't reproduce this by the same method (this time the validation layer was from vulkan-validation-layers 1.3.290-2. However, I do get a different failure mode: CS2 hangs during startup, with a black screen, using 100% of a CPU core. I don't know whether this is evidence of a different (related?) problem, or whether it's just the validation layer making CS2 startup really, really slow.

In the .json file, override_paths needs to point to the directory containing the locally built .so [file]

If I'm reading the specification correctly, override_paths needs to point to the directory containing the locally-built layer's JSON manifest. In your locally-built layer, maybe that is the directory containing the .so file, but only by coincidence.

The fundamental problem here is that there are two copies of std::regex in action here: the one in the host system's libstdc++ as linked by the Vulkan layer, and the one in the libstdc++ that the game engine links statically.

On reflection, I don't think this is actually a Steam Runtime problem, more like a game-engine problem. If we were running the game without using the SLR container, its statically-linked copy of (part of) our SDK's compiler's libstdc++ would be equally able to conflict with the host system's libstdc++, unless they happened to be the same version (which is obviously not possible in general, because the environment used to compile the game can't possibly have the same libstdc++ version as both Arch and Ubuntu at the same time).

So I think this issue report should perhaps move to https://github.com/ValveSoftware/csgo-osx-linux, or be closed as "not planned" for the container runtime - it's only CS2 developers who will be in a position to be able to address this.

It would be better if we can avoid the Source2 engine triggering this problem from the engine end, but that's difficult to achieve (I have a couple of ideas which might potentially help there).

I made a simplified mockup of this situation, and while I couldn't figure out how to reproduce a similar crash, I was able to test out my ideas by inspecting the symbol tables. Based on that, I've made some suggestions internally (reference for maintainers: steamrt/tasks#547) which might provide ways to resolve this.

Until then, you have some workarounds (linking your Vulkan layer's libstdc++ statically as well, or loading it via VK_INSTANCE_LAYERS instead of a meta-layer).

I'd rather keep it here since it's focused on the general problem of distributing binaries on Linux that steam-runtime aims to fix, and generally not a problem restricted to CS2.

Yeah, reasonable. Perhaps when we've figured out how to avoid this problem in CS2, we can add a note to https://gitlab.steamos.cloud/steamrt/steam-runtime-tools/-/blob/main/docs/slr-for-game-developers.md?ref_type=heads#making-a-game-container-friendly (or some more general document about building generally-usable Linux binaries) with recommendations for good patterns to use and anti-patterns to avoid?
