Let's look at inet6_pfil_hook. It's only called in "if_bridge.c" by bridge_pfil, bridge_fragment, bridge_dummynet, bridge_broadcast, bridge_ioctl, bridge_ioctl_add, bridge_forward, and bridge_input. These are all statics. Is there something going on with inlining and "garbage collecting"? Do I have C flags messed up? I'm not sure how this is works as I see that "_bsd_inet6_pfil_hook" is defined in ip6_input.c and the object is in the built libbsd.a. I see there's some -Bstatic and -Bdynamic stuff going on in the link. Start of the link of netshell01. I can send more info if you'd like, I don't want to swamp the list.
