Thanks for posting this patch. I had to manually merge a few of the
files because of Simo's event context changes, but those were quite
However when I attempted to build, I got warnings and errors because
lib/util/util_ip.h (and I'm assuming the corresponding function
implementations in lib/util/util_ip.c) could not be found.
I believe these files were omitted from your patch because Git does not
include any added files in a "git diff" unless those files have been
explicitly added using "git add". I can see the changes to
lib/util/config.mk that reference util_ip.o, but I see no other Makefile
changes that would make me look for any more added files.
Could you please post lib/util/util_ip.[ch]? If you could post just
those 2 files separately, I could easily pull them into what I have
already merged with your original patch.
