[macOS] system crashed while using systemExtension.

We've recently noticed frequent crashes on the macOS system after an OS update when using the system extension with NETransparentProxyProvider. Below are the crash logs that appear in a pop-up after the machine starts.

I'm having difficulty understanding the exact point at which it crashes, and it shows my process below.

Panicked task 0xfffffe2d0a36abf8: 8190 pages, 143 threads: pid 9134: com.xxxx.na Panicked thread: 0xfffffe236ea13010, backtrace: 0xfffffe67858d2b80, tid: 337348

Detailed logs attached.

Is this your NE product? Or one from some other developer?

Regardless, kernel panics are always bugworthy and I encourage you to file a bug about this issue.

Please post your bug number, just for the record.

  • By mistake, I created a bug in a different category. This is the correct bug: FB13465642

Thanks for filing that.

My panic fu is rather dated but my best guess is that the kernel has panicked due to an unmapped memory exception at (or near) this code in the in-kernel TCP/IP stack. There’s not a lot you can do about this. Apple’s kernel team is going to have to investigate and fix the issue.
