Hi all,
I've got an NKE that works fine for OS X networking but fails on inbound
packets to Classic applications. By Classic I mean running in Classic mode,
not booted into < 10. For example, ftp. I can create an ftp session from the
terminal just fine, but using Fetch in Classic fails. I've tried various
different things to try to fix this; pull-ups, copies, etc., but nothing
seems to be working. I grabbed clear packets and re-injected them with
success, so it seems that it's definitely something with the packet I'm
processing. When I process the inbound packet, the dlil_inject_if_input call
returns good status, but nothing gets to the Classic app. When looking at
the inbound mbuf vs. the mbuf I create and inject, the only real difference
that I see are the csum_flags and csum_data field are set in the original
mbuf, but zeroed in the one I inject. Is this a problem, or is there some
magic bit I need to flip to make this work for Classic (and not break the
working MacOS X)?
So I guess my real, basic question is, what's different between MacOS X and
Classic networking?
Thanks!
