To answer the main question everyone is asking... I just wanted to do an integrity test on the kext. I could hard code the 'supposed' path into the integrity code but as you said "... kext may be deleted from /System/Library/Extensions (or wherever)..."

Can anyone suggest or point me in the right direction as to be able to determine the path that my kext is running from? I want my user land application to be able to retrieve the path that the connected kext is running from.

I looked at this issue a while ago (10.3) and followed the loading code all the way through. AFAICT there is no way to determine the path the kext is 'running from', because it is discarded after loading. This is partly because kexts don't run from a path: they are loaded and wired, and then no longer depend on the filesystem. In fact whole kext may be deleted from /System/Library/Extensions (or wherever) and have no effect on the running system.

If needed I would retrieve the path from the kext via a getsockopt call. Unless there is some other way via the user land application.

This is the kind of comment which usually provokes the question: 'What are you trying to do?' :)

Thanks

Carl
