Hi,

I'm trying to pin down a memory corruption in my kext, and I found out that the latest kernel supports KASAN. However, when trying to compile it I get the following error:

make[7]: *** No rule to make target `xnu-4570.41.2/san/kasan-blacklist-dynamic', needed by `xnu-4570.41.2/BUILD/obj/KASAN_X86_64/san/KASAN/kasan_blacklist_dynamic.h'. Stop.

I see that 'kasan_blacklist_dynamic.h' is generated via 'san/tools/generate_dynamic_blacklist.py', but for it to work the script has to be pointed to 'kasan-blacklist-dynamic' file, which is missing.

Is there any workaround available? Or is this functionality only for internal use?

This should do the trick: $ echo '__kernel__:_ZN6OSKext8copyInfoEP7OSArray:memld' > san/kasan-blacklist-dynamic _______________________________________________ Do not post admin requests to the list.
