    Mac OS X provides a socket-based API to communicate with Kernel Extensions (KEXTs) called "KEXT Controls". For this, Mac OS X defines PF_SYSTEM as a new socket domain which supports the SYSPROTO_CONTROL protocol.

    Right now the PF_SYSTEM domain and the SYSPROTO_CONTROL protocol are not supported by Python's socket module. I am attaching a patch that introduces support for both.

    More information on KEXT Controls can be found here:

    The patch fails to apply in configure.in. Can you please regenerate it?

    Also: Can you propose test cases for this socket family?

    Here is the regenerated patch.

    To write a test case I would need a PF_SYSTEM socket to connect to. As far as I know Mac OS X doesn't provide a demo socket for this.
