Bug ID: 35991 Summary: Communication via COM1 crashes the app Product: Wine Version: 1.7.16 Hardware: x86-64 OS: Linux Status: UNCONFIRMED Severity: critical Priority: P2 Component: ntdll Assignee: wine-bugs@winehq.org Reporter: sh.yaron@gmail.com

Created attachment 48115 --> http://bugs.winehq.org/attachment.cgi?id=48115 Backtrace from after the crash.

I was trying to load the project with PLC online communication but apparently when I tried to check the connection the app crashed, backtrace attached.

The PC is connected to COM1 of the PC.

--- Comment #1 from Nikolay Sivov bunglehead@gmail.com --- Hi, Yaron.

What kind of PLC is that? What's a program name? Do you have sources? (it's a Borland C++ Builder application so it seems)

--- Comment #2 from Yaron Shahrabani sh.yaron@gmail.com --- Hi, and thanks for the quick response!

The PLC if manufactured by Fatek, the model is FBs14(MAR2).

The program name is WinProladder.

Sorry for not filling that up, I submitted the app to the AppDB and wanted to link it but it will take some time until confirmed.

It does look so… do you think it will pose any issue? The apps looks very usable…

Yes, and I have the device and the cable. Feel free to guide me.

--- Comment #5 from Anastasius Focht focht@gmx.net --- Hello folks,

confirming.

Can be reproduced without actual device, you just need a serial port (USB-to-serial adapter).

Create the dosdevice symlink (COM1) and have the app doing the scan the port using different baud rates/settings.

The app creates a reader thread which carries out the serial communication to decouple/avoid blocking the user interface. The reader thread calls 'WaitCommEvent' with a thread-stack based 'lpEvtMask' buffer (out parameter).

WaitCommEvent() returns with ERROR_IO_PENDING (expected) and the thread issues an overlapped ReadFile() which is waited on with WaitForMultipleObjects().

At one point the serial comm reader thread decides to give up, issues PurgeComm(), closes the event handles (cleanup) and terminates itself.

Earlier, Wine created an async worker in IOCTL_SERIAL_WAIT_ON_MASK ioctl handler using RtlQueueWorkItem(), which kicks off a poll routine in another thread, see wait_on() here:

http://source.winehq.org/git/wine.git/blob/a890d0f030a864d893646bd0c29dd7617...

A short time later the async worker polling loop figures out something is wrong ('get_modem_status' failed) and writes zero to the user-supplied event mask buffer.

This causes the crash because the original reader thread already terminated at that point and the buffer (thread stack variable) is no longer accessible -> *boom*

I've already stated 10 years ago in comment #5 that you don't need the actual PLC hardware. Anything that provides a serial device, for example some USB-to-serial adapter cable can work as reproducer.

The problem was fixed only recently by commit https://gitlab.winehq.org/wine/wine/-/commit/35de72453c4e60876c8ff79280982ef... ("ntdll: Move IOCTL_SERIAL_WAIT_ON_MASK to the server."). Part of Wine 9.11 release.

Thanks Elizabeth.

I've recovered a slightly different version of the PLC software from Internet Archive since the original vendor links were no longer working (v3.28 vs v3.23). The problem was there present as well.
