I had problems including the ipchains compatability compiled into the
kernel, or as a versioned module.
For some reason (that I've failed to get to the bottom of) selecting
ipchains compatability to be compiled into the kernel doesn't end up
with the code included.
The following are set in .config:
CONFIG_NETFILTER=y
CONFIG_IP_NF_COMPAT_IPCHAINS=y
CONFIG_IP_NF_NAT_NEEDED=y
The code is compiled, and included in net/network.a, but does not get
included in vmlinux. Using nm to look for the symbol ipfw_init_or_cleanup
demonstrates this:
alfie@bagpuss$ nm net/ipv4/netfilter/netfilter.o | grep ipfw_init_or_cleanup
000019e4 T ipfw_init_or_cleanup
alfie@bagpuss$ nm net/network.a | grep ipfw_init_or_cleanup
000019e4 T ipfw_init_or_cleanup
alfie@bagpuss$ nm vmlinux | grep ipfw_init_or_cleanup
alfie@bagpuss$
There is another problem when you compile as a module, when you have
CONFIG_MODVERSIONS defined. The source files that compile into the
ipchains module do not include "module.h", so you have unversioned
symbols imported, and the resultant module will not load.
I fixed this by adding "#include <linux/module.h>" to a wild selection
of files in net/ipv4/netfilter. I haven't produced a patch, as I don't
know if I've gone over the top, and if I should remove the inclusion of
"<linux/config.h>", as this is included by "<linux/module.h>".
