Segmentation fault in ilc when building native code for System.Reflection.Tests (NativeAOT, ARM64, Ubuntu 18.04) #71270

Closed Beau-Gosse-dev closed 2 years ago

Beau-Gosse-dev commented 2 years ago

Notes

Reproduction Steps

  1. On ARM64 Ubuntu 18.04
  2. Make sure bin artifacts are cleared out to rebuild rm -rf /home/ubuntu/code/runtime/artifacts/bin/System.Reflection.Tests/
  3. Make sure obj artifacts are cleared out to rebuild rm -rf /home/ubuntu/code/runtime/artifacts/obj/System.Reflection.Tests/
  4. Navigate to reflection tests cd ~/code/runtime/src/libraries/System.Reflection/tests
  5. Run tests for NativeAOT ../../../../dotnet.sh build /t:Test /p:TestNativeAot=true -c Release -v d

Debugging Steps (after running Reproduction Steps):

  1. Setup symbols for debugging cp /home/ubuntu/code/runtime/artifacts/bin/coreclr/Linux.arm64.Release/*.dbg /home/ubuntu/code/runtime/artifacts/bin/coreclr/Linux.arm64.Release/ilc
  2. Point gdb to ilc gdb /home/ubuntu/code/runtime/artifacts/bin/coreclr/Linux.arm64.Release/ilc/ilc
  3. Tell gdb where symbols are set debug-file-directory /home/ubuntu/code/runtime/artifacts/bin/coreclr/Linux.arm64.Release/ilc
  4. Run against reflection tests r @"/home/ubuntu/code/runtime/artifacts/obj/System.Reflection.Tests/Release/net7.0/native/System.Reflection.Tests.ilc.rsp"

Could you please get a stacktrace of the crash with symbols? You may need to tell the gdb to load the symbols from /home/ubuntu/code/runtime/artifacts/bin/coreclr/Linux.arm64.Release, or copy the *.dbg files from /home/ubuntu/code/runtime/artifacts/bin/coreclr/Linux.arm64.Release to /home/ubuntu/code/runtime/artifacts/bin/coreclr/Linux.arm64.Release/ilc.

Beau-Gosse-dev commented 2 years ago

Thanks, @jkotas I was wondering how to get the symbols. I've updated the original issue with the symbol filled bt.

When running in gdb, I did see warning: the debug information found in "/home/ubuntu/code/runtime/artifacts/bin/coreclr/Linux.arm64.Release/ilc/libclrjit.so.dbg" does not match "/home/ubuntu/code/runtime/artifacts/bin/coreclr/Linux.arm64.Release/ilc/libclrjit.so" (CRC mismatch).

Is that actually an issue?

Are there any instructions for cross-building these tests with NativeAOT somewhere?

jkotas commented 2 years ago

It should work like any other cross-build. Build Linux arm64 Release NativeAOT CI job cross-builds. The command line that it uses (needs rootfs setup):

build.sh -ci -arch arm64 -os Linux -s clr.alljits+clr.tools+clr.nativeaotlibs+clr.nativeaotruntime+libs+libs.tests -c Release /p:TestNativeAot=true /p:RunSmokeTestsOnly=true /p:ArchiveTests=true /p:CrossBuild=true /p:MonoLLVMUseCxx11Abi=true

on multiple machines and configurations I have tried now.

jkotas commented 2 years ago

This error means that a wrong corelib is being used. The libraries partition build tends to stick to first corelib that it has seen, so if you build one flavor of the runtime and then a different flavor of the runtime, the libraries partition will still use the corelib for the first flavor of the runtime.

Either build using above command line from a clean environment; or manually copy over the right corelib (the one from artifacts\bin\coreclr\linux.arm64.Release\aotsdk) to where the build script expects it.

jakobbotsch commented 2 years ago

Thanks, that seemed to be it. I was trying to get it to use a checked build.

Removing /p:RunSmokeTestsOnly=true which I assume is necessary to build System.Reflection.Tests unfortunately led me to more problems with the build quickly exhausting my machine of memory with 20+ instances of ilc each consuming multiple gigabytes of memory. For posterity, after some binlog digging I ended up with

../../../../dotnet.sh build -c Release /p:TestNativeAot=true /p:CrossBuild=true /p:TargetOS=Linux /p:TargetArchitecture=arm64 /p:BuildArchitecture=x64

to cross build just the one test project. Unfortunately, this does not repro the issue for me on a cross-build.

The strange part here is that the failing source line (the one which the segfault is occurring on) is accessing a pointer that has been null-checked just a couple of lines before, so there is probably either some uninitialized data access going on, or some native heap corruption/use after free going on.

I will try to see if I can manage to build this on a ARM64 host machine.

jakobbotsch commented 2 years ago

I was not able to reproduce this on either Ubuntu 20.04 or Ubuntu 18.04 when building through WSL on my Surface Pro X. @Beau-Gosse-dev can you share a dump including the contents of the artifacts/bin/coreclr/Linux.arm64.Release/ilc folder?

I'll try to reproduce this again and get a dump next week.

Hmm, seems like a new issue was introduced since this was opened. For some reason I can't even build "clr.alljits" and get this:

Does anyone know what that issue might be from or how to debug it further?

@Beau-Gosse-dev the lines that have the info on how things failed might be further up in the log. Could you share a bit more of it please?

llvm-objcopy-6.0: Unknown command line argument '--only-keep-debug'. Try: '/usr/bin/llvm-objcopy-6.0 -help'

@janvorli @am11 This seems to be caused by the recent changes to use llvm-objcopy

hoyosjs commented 2 years ago

The issue is llvm-objcopy-6.0 doesn't have the --only-keep-debug argument somehow. This is likely from https://github.com/dotnet/runtime/pull/71446. Looks like a quick workaround might be to only leave one hyphen in https://github.com/dotnet/runtime/blob/f54ec728b0c836f6633b9ce52c9fe97452e5232e/eng/native/functions.cmake#L429 (or remove it altogether, the help scpecifies:

-only-keep-debug Currently ignored. Only for compatibility with GNU objcopy.

jkotas commented 2 years ago

Can we require some more recent llvm version as minimum instead?

am11 commented 2 years ago

We can also detect if the argument is missing and adjust the condition accordingly. e.g. this is how we detect if dsymutil supports --minimizeon macOS: https://github.com/dotnet/runtime/blob/eb123a7f77a9e453b2a67e99525598ece83bcabe/eng/native/functions.cmake#L405-L413

hoyosjs commented 2 years ago

This was llvm-objcopy 8, we probably need to check dynamically if we are going to support using RedHat's version of clang for RHEL7 (llvm 7)

jakobbotsch commented 2 years ago

Assuming the above is resolved now. Are you still able to reproduce the issue and can you share a dump if so @Beau-Gosse-dev?

ghost commented 2 years ago

This issue has been marked needs-author-action and may be missing some important information.

Beau-Gosse-dev commented 2 years ago

So it seems like the second issue, not being able to build clr.alljits, is fixed. However, the original issue still reproduces. Here is the new BT from gdb (seems the same as the original issue).

@jakobbotsch When you say you want the dump is that generated in gdb with generate-core-file ~/dumpfile ? When call that, the output file is 4.6G, is that what you want me to upload? I may need to find a new place to host it, I'm not sure GitHub allows files that big.

@jakobbotsch When you say you want the dump is that generated in gdb with generate-core-file ~/dumpfile ? When call that, the output file is 4.6G, is that what you want me to upload?

Yes, that and the ilc folder contents would be helpful. You might be able to make a smaller repro using --singlemethodtypename and --singlemethodname args to ilc, if you can dig out the exact function it is compiling that is causing the problem (that is probably visible in the log if you do a run with --verbose and --parallelism 1 first).

jakobbotsch commented 2 years ago

Looking at the dump clang's codegen for AdvanceCall looks incorrect. it is skipping a null check that is present in the source code. In fact, it is missing a lot of code present in the source code due to assuming this null check always passes.

I can see that the JIT in the dump you sent me is built with clang-6. Can you try a newer version of clang? The codegen for this function looks completely different for me using clang-9.

Thanks! I created a new VM and installed clang-9 instead of just "clang" and that fixed the issue. I see that in the Linux Requirements it says clang-9. I must have just installed the default clang after seeing an error that clang was not found.
