SIGSEGV when independent DSA keys are concurrently disposed

[vcsjones]

On macOS Monterey, I would expect this program to run forever.

using System.Security.Cryptography;

DSA dsa;

void Work()

    while (true)
    {
        try
        {

            // Managed exceptions are okay, looking for crashes.

    }
}
Thread t1 = new Thread(Work);
Thread t2 = new Thread(Work);

t1.Start();
t2.Start();
t1.Join();
t2.Join();

It will quickly exit with status code 139, a segmentation fault.

I cannot reproduce this for RSA or ECDsa, only DSA.

The native stack trace is below. Unfortunately I've been struggling quite a bit to get dotnet-sos and dotnet-symbol to work on Apple Silicon, so no managed stack trace.

Maybe it's time to just mark DSA.Create() as [UnsupportedOS("macOS")] and rip out DSASecurityTransforms.

@GrabYourPitchforks, thoughts?

[vcsjones]

Oh, hm. Not sure how I misread that. Regardless, we can open a separate issue for that test failure then, if we want. But if we deprecate DSA on MacOS then it would have the same result.

[filipnavara]

DSA is the only algorithm that uses the old CSSM keys (aside from X509Certificate impl. calling into it). Given the fact that it was always limited to one size of key and key creation didn't work I would be fine with deprecating it. That said, it would be nice to understand the problem so the X509 classes don't run into it.

The fact that this comes from finalization worries me. All the handles should have been disposed properly.

[filipnavara]

Ah, I see now that the managed catch is always triggered which explains why the handles are leaked. I didn't realize the DSA object is shared between the threads.

Okay, multithreading and concurrency is not related. Just letting DSA objects get finalized will crash.

Simpler repro (takes longer to crash, but still happens pretty quickly)

using System.Security.Cryptography;

The fact that this comes from finalization worries me. All the handles should have been disposed properly.

If both threads hit the line _keys = newKeys at the same time, one of the two newKeys values will be lost to the GC/finalizer.

"longer" is an understatement. Running that on .NET 7 didn't crash for 2 hours now 😅
