If you go to inject a packet inbound, you will need to set the rcvif to something as well as fiddle with the packet to get it in the right state. Thanks, Josh. I had this concern in the back of my head that rcvif might be used on the outbound path for something other than the "interface the packet was received on" (something in ipsec code maybe). In any case, you (Carl) should preserve the value you find in the mbuf that you are going to copy, just to be on the safe side. I don't think that there is a timing problem lurking in there, but reviewing the kernel code in this area can't hurt. This email sent to site_archiver@lists.apple.com
