Sometimes macOS Kernel decides to KP in some com.apple.kec.pthread code.

Sometimes you may want to get the symbols for the KP backtrace.

Problem:

com.apple.kec.pthread is not provided in the KDK (macOS 10.12.3)

com.apple.kec.pthread is not loaded at the same address as "kernel".

Question:

Where is this com.apple.kec.pthread thing coming from?

Is it provided in the KDK with a non intuitive name?

I haven’t looked into the details of this but this KEXT is part of pthreads.

$ grep com.apple.kec.pthread /System/Library/Extensions/pthread.kext/Contents/Info.plist
    <string>com.apple.kec.pthread</string>

The source is in Darwin, in the

libpthread

project (can’t give you a link because

opensource.apple.com

is having a bad day).
