Just looking in /sys/netinet and I see this:
(freefall:~/src/sys/netinet) grep 'inetsw' *.c | grep protosw
in_proto.c:struct ipprotosw inetsw[] = {
in_proto.c: (struct protosw *)inetsw,
in_proto.c: (struct protosw *)&inetsw[sizeof(inetsw)/sizeof(inetsw[0])], 0,
ip_fil.c:extern struct protosw inetsw[];
ip_icmp.c:extern struct protosw inetsw[];
ip_input.c:extern struct ipprotosw inetsw[];
ip_mroute.c: extern struct protosw inetsw[];
ip_output.c:extern struct protosw inetsw[];
To me this looks like a recipe for disaster.
Why is there "struct ipprotosw inetsw" and "struct protosw inetsw" ?
Does this really mean that someone wanted to change "struct protosw"
and instead made up "struct ipprotosw" and are trying to squeeze that
somehow into "protosw" ?
Ideally I should be able to put inetsw into a header file and extern it,
but with this, I don't see how that would make sense...
