Xcode 15 RC NIO-ELT-0-#0 (82): EXC_BAD_ACCESS (code=1, address=0x0) Error #1648

Eggsy94 · 2023-09-13T05:44:28Z

Describe the bug

During the process of calling the getTLSVersionSync method in my Swift code, I encountered an error at the line where NWProtocolTLS.definition is referenced. This is a critical part of the method that attempts to fetch the TLS version either from the Network framework or NIOSSL. I'm not sure why the error is occurring, but need assistance in resolving it.

I am currently using grpc-swift version "1.15.0" / Xcode version 15.0 RC

To reproduce

The steps to reproduce this bug are as follows:

class EventLoopGroupProvider {
  static let shared = MultiThreadedEventLoopGroup(numberOfThreads: 1)
}

public protocol InitializableGRPCClient: GRPCClient {
  init(channel: GRPCChannel, defaultCallOptions: CallOptions)
}

public protocol gRPC_ClientProtocol {
  associatedtype Client: InitializableGRPCClient
  static func makeClient(_ callOptions: CallOptions) async throws -> Client
}

public extension gRPC_ClientProtocol {
  static func makeClient(_ callOptions: CallOptions = .init()) async throws -> Client {
    try await withCheckedThrowingContinuation { continuation in
      DispatchQueue.global(qos: .background).async {
        do {
          let endpoint = "tls-\(AppSetting.shared.gRPC_EndPoint)"

          let channel = try GRPCChannelPool.with(
            target: .host(endpoint),
            transportSecurity: .tls(.makeClientConfigurationBackedByNIOSSL()),
            eventLoopGroup: EventLoopGroupProvider.shared
          )
          let client: Client = .init(channel: channel, defaultCallOptions: callOptions)
          continuation.resume(returning: client)
        } catch {
          continuation.resume(throwing: error)
        }
      }
    }
  }
}

gRPC Server Description

There was no problem with TLS processing for that packet.
However, as soon as the client sends the data encrypted with the session key exchanged in TLS, it is immediately disconnected on the server side.

What error do you see?

There was no problem with TLS processing for that packet.
However, as soon as the client sends the data encrypted with the session key exchanged in TLS, it is immediately disconnected on the server side.

Have you tried looking at a packet capture or logs?

Eggsy94 · 2023-09-14T05:10:08Z

What error do you see?

No, there was no error log at all.
just NIO-ELT-0-#0 (83): EXC_BAD_ACCESS (code=1, address=0x0)

And in the same thread stack GRPCIdleHandler line 257
let tlsVersion = try? context.channel.getTLSVersionSync()
Everything below has since been moved to the Swift-nio library stack.

Have you tried looking at a packet capture or logs?

yes using Wireshark

rvictl -s UDID
ifconfig rvi0

Can you provide the full crashing call stack please?

Is this enough?

Lukasa · 2023-09-14T14:53:37Z

Yes, it might be. Do you have a full crash report? This looks to me like a crash getting NWProtocolTLS.definition, but I'd like to double-check it.

This is everything. Is this what you want?

Oh sorry, I wanted a crash report as derived from Console.app. The crash appears to be here, which would imply that this is an issue in your OS (and would require a feedback report to Apple), but there are a few other places the crash might manifest.

Eggsy94 · 2023-09-15T09:36:46Z

log.md
Here is the Consol.app from the first grpc call to the crash when starting the app.

Lukasa · 2023-09-18T09:37:33Z

Ah sorry, I was looking for a crash report, which is in the "Crash Reports" section of the sidebar.

Eggsy94 · 2023-09-18T14:11:59Z

I think I've given you everything you can extract from the iOS app, not the Mac app. What more do you need? The crash report on the Console.app side only shows crash reports running on Mac.

Lukasa · 2023-09-18T14:17:43Z

You should be able to transfer the report: https://developer.apple.com/documentation/xcode/acquiring-crash-reports-and-diagnostic-logs#Transfer-crash-reports-and-device-logs-to-a-Mac

Eggsy94 · 2023-09-19T01:29:35Z

Thank you, I learned one more thing thanks to you
This is what you want, right?

That crash report is interesting because it shows a different call stack, this time we have a jump to zero in the TLSVerificationHandler. That seems inconsistent with your original report. Do your crashes still reproduce in GM Xcode?

Eggsy94 · 2023-09-22T10:52:22Z

That's right, I'm so sad and I want to use XCode15 quickly

Eggsy94 · 2023-09-25T06:11:19Z

Would it be possible to expedite the review of this issue? We are more than willing to provide any additional information you may need to accelerate the debugging process.

Thank you for your continued support.

Given that the crashes reproduce in GM Xcode, I think this is an issue with Network.framework. Can you file a feedback request using Feedback Assistant and post the number here?

Eggsy94 · 2023-09-25T07:39:52Z

I submitted feedback to Apple
post number is FB13203435

Eggsy94 · 2023-10-05T16:09:33Z

@Lukasa
Is all I can do is wait?😥

Lukasa · 2023-10-05T17:38:26Z

Can I suggest adding a sysdiagnose to your feedback?

Eggsy94 · 2023-10-06T01:42:21Z

ok I did add sysdiagnose in feedback

anandnool · 2024-04-08T15:48:08Z
