[linux] Segfault while invoking Roslyn's csc.dll with long command line #98936

Open grendello opened 8 months ago

grendello commented 8 months ago

The crash happens occasionally (every 4-5 builds) when building .NET Android's Mono.Android project, which passes a very long command line to the Roslyn C# compiler (1.8Mb long, over 11k parameters). It started happening with bump to the latest dotnet 9 preview, dotnet/installer/main@0a73f814e1 9.0.100-preview.2.24122.3.

Environment info:

OS: Debian/testing (trixie) Arch: amd64 CPU: AMD Ryzen 9 5950X 16-Core Processor Kernel: 6.7.6-x64v3-xanmod1

The crash doesn't happen on every build, but it appears the more parallel the build, the crashier the process becomes. It also appears that putting the long command line in a response file mitigates the issue, at least I wasn't able to reproduce the crash this way after 20 attempts. When the crash happens, runtime just goes away silently without capturing the signal and printing any information. Our CI Linux bot uses Ubuntu 20.04.6 LTS and, so far, doesn't appear to experience this crash (or we were lucky, as it only landed last Friday)

Unfortunately, to reproduce locally one would have to build Xamarin.Android on their machine and extract the csc invocation from binlog. This is necessary because the build uses a lot of artifacts produced by .NET Android build. I will be happy to provide assistance in that regard, if necessary :)

I extracted the compiler invocation into a shell script and captured a handful of coredumps, the best trace I managed to get is below:

AFAIR Linux doesn't support such line lenghts and it truncates them, can't find a reliable answer on google though since various results say that either 1024, 2048, 4096 or 128k chars is the limit.

grendello commented 8 months ago

The line limits are higher than on macOS (which has 1M):

$ getconf ARG_MAX
2097152

And it appears that OS-imposed line length limit is not a factor here, since named pipes appear to be used to pass arguments to the sub-process. Command line length may play a role in either dotnet or Roslyn argument parsing, but it might be a red herring too.

grendello commented 8 months ago

Just tested with the new dotnet, 9.0.0-preview.2.24123.1, and the crash still happens in the same way

mangod9 commented 6 months ago

Hello @grendello, are you able to share the dump and/or a repro for this issue?

grendello commented 6 months ago

Hello @mangod9, I didn't save any of the original core dump files, alas, but I've just tested with dotnet 9.0.100-preview.5.24229.2 and wasn't able to reproduce this issue anymore. It seems that it "fixed itself" :)

I will close the issue and reopen it only should I see the crash again. Thanks!

grendello commented 6 months ago

@mangod9 well, it started happening again with the update to 9.0.100-preview.5.24262.2 and here's the trace for the crash:

In hope to get better traces, I built dotnet/runtime's main branch (at commit 9e57de2b2a71b449057ffe75823d332e44ffe8fa` in Debug configuration but, alas, the segfault doesn't happen. What happens in this instance, however, is that where the runtime would segfault it hits the following assertion:

Good news is that dotnet/runtime main branch built with build.sh -c release -gcc-14 doesn't crash, however without knowing the codebase it's hard for me to say whether the problem is fixed or (as it previously happened) whether it "vanished" for a while.

akoeplinger commented 4 months ago

The official builds happen with llvm instead of gcc so this might still be an issue.

If you want to try building something closer to the official build you can use the docker container mcr.microsoft.com/dotnet-buildtools/prereqs:azurelinux-3.0-cross-amd64-net9.0 and build via ROOTFS_DIR=/crossrootfs/x64 ./build.sh -cross

grendello commented 4 months ago

@akoeplinger I used gcc because the runtime failed to build with clang 18 in release (or, rather, failed to link). I'm about to try with a different version of clang.

grendello commented 4 months ago

Rebuilt the current tip of main (4babcb3bdff91feea8933f76e346b4e998c17b3d) with clang 16 and it still doesn't crash, so maybe (fingers crossed) it's fixed.

mangod9 commented 4 months ago

ok interesting. If you do repro it again please capture dumps (esp. the assert you hit on debug). Thanks.

Adding @davidwrighton since Thread::DeleteThreadStaticData was recently touched. David, have you seen this issue after you thread static changes?

davidwrighton commented 4 months ago

I'm looking into this

davidwrighton commented 4 months ago

@mangod9, @grendello Well, the assertion you found with our latest bits is definitely a bug, but not related to the other issue you've been looking at. I'm in the process of writing a reliable test for the assertion failure issue, and it'll be fixed in main probably later this week, but it won't fix the segfault problem. This assertion failure issue could in principle result in a deadlock, not a crash.

mangod9 commented 4 months ago

yeah agree this isnt related to the original issue. @grendello if you arent able to repro the main bug we can close after David makes the fix.

davidwrighton commented 4 months ago

The assertion issue is in process of being fixed with pr #104003

Once your fix lands, I will test the debug build again to see if I can repro the original issue in this configuration. I guess the assertion stood in the way of it.

Alas, the issue appears to be back with the tip of main (469c5417dd70797dd22d5d7aae0dde2af8c07106). Previously, I tested it with 4babcb3bdff91feea8933f76e346b4e998c17b3d and I couldn't reproduce the crash over several iterations. However with 469c5417dd70797dd22d5d7aae0dde2af8c07106 crashes reliably on each attempt.

For both commits, the same compiler (clang 16.0.6) was used, with the same build command line (./build.sh -c release), here's the segfault stack trace from the latest crash:

The 2nd trace isn't very helpful, but the bottom frames are at least the same in both cases. Might it be an issue of thread synchronization in the GC code?

grendello commented 4 months ago

A workaround has presented itself, and a clue (I think) at the same time. Disabling background GC makes the build work. I disabled it only for csc.dll via its csc.runtimeconfig.json file.

grendello commented 4 months ago

The workaround doesn't remove the issue completely, but it makes the crash much less likely. I've just had the first one in around 20 builds. The stack trace for this crash is not complete, alas:

grendello commented 3 months ago

An interesting observation is that when I keep getting the segfaults, dropping all the kernel page and slab object caches, as well as flushing filesystem caches help:

# sync -f
# echo 3 > /proc/sys/vm/drop_caches

Makes me wonder if it could be some uninitialized and not properly cleared memory somewhere in the native GC code? When dotnet keeps crashing, it's possible that subsequent runs of it would reuse shared libraries already mapped in memory and kept around in the caches. If this happens and the runtime doesn't initialize (or clear after use) some variable(s), invalid values may cause it to go astray. /proc/sys/vm/drop_caches documentation can be found here.

mangod9 commented 2 months ago

Hey @grendello, does this continue to repro on recent main?

grendello commented 2 months ago

@mangod9 in the past ~10 days I haven't seen any crashes, things look hopeful atm. We're currently using 9.0.100-rc.2.24426.2

mangod9 commented 1 month ago

is this ok to close now?

grendello commented 1 month ago

I think so, but it would be good to know what was the problem :) Any idea what fixed it?
