I am trying to add ipset to an old system (kernel 2.6.16)
So I downloaded the old ipset and built it in a separate directory.
There was a little changes necessary, indicating that the distro had some stuff
backported into the kernel, but eventually it succeeded. I can create ipset,
add addresses to it and list them.
Now, when I try to add iptables rule, I get error about missing libipt_set.so
I have tried to recompile iptables on the machine (version 1.3.5 like the installed one),
but that does not build the missing file.
It seems that include/linux in iptables does not contain files from include/linux in ipset.
Would it make sense to just copy over these files? Are there any other changes necessary?
I had *exactly* the same problem over a year ago - trying to build ipset
4.4 (the newest version in those days) on an old kernel (2.6.16.60, if
memory serves).
If you look at the archives of this mailing list for a thread called
"ipset-4.4 on 2.6.16.60 kernel" from 06/07 Nov 2010 you will find all
the answers you need. From what I remember I had to fix both the ipset
source code (the instructions for building and incorporating ipset 4.x
into the older kernel versions as shown on ipset.netfilter.org are
*incomplete*) by applying a patch to the ipset source. I had to rebuild
iptables - also from source.
...
I've just looked at my past activities and found instructions how to
incorporate ipset 4.4 into the 2.6.16.60 kernel - incorporating ipset
4.5 with your version of the kernel and iptables would, I guess, be very
similar. I enclose a patch which I applied at the time to the kernel
source and a set of instructions I followed, which got me out and
allowed me to rebuild iptables and ipset. The crucial part is to modify
slightly the kernel source, rebuild iptables, patch ipset and then
rebuild it against both the (modified) kernel source tree and the newly
compiled-and-installed iptables. This is what I did at the time:
=======================
I. Prerequisites:
1. kernel & iptables sources
2. ipset source - I initially did this with v4.4, but 4.5 is also fine
and the process of applying the patch/building the kernel and iptables
is identical.
II. Installation instructions:
1. Source code preparations:
I am assuming that the kernel source tree is at /usr/src/kernel/ and
ipset-4.4.tar.bz2 is downloaded in /root and the attached
ipset-4.4.patch is also in /root. In this case do the following (as root!):
cd /root
tar -jxf ipset-4.4.tar.bz2
cp ~/ipset-4.4/kernel/include/linux/netfilter_ipv4/ip_set.h
/usr/src/kernel/linux/include/linux/netfilter_ipv4
cp ~/ipset-4.4/kernel/include/linux/netfilter_ipv4/ipt_set.h
/usr/src/kernel/linux/include/linux/netfilter_ipv4
Build and install iptables in the usual way pointing out the source
kernel tree as above (/usr/src/kernel/). At the end of the process,
check that you have (at least) two new files installed:
/usr/lib/iptables/libipt_SET.so and /usr/lib/iptables/libipt_set.so!
2. Building and installing ipset 4.4 (for 4.5 this is almost identical -
the attached patch only needs to be tweaked slightly, if at all!)
Before you start doing anything you need to alter the source so that it
can be compiled without any errors. Fortunately I enclosed a patch which
makes the job a bit easier. To apply the patch do the following (as root):
patch -p1 --dry-run < ipset-4.4.patch
If there are no 'hunk' or other errors/warnings you can do the following:
patch -p1 < ipset-4.4.patch
The ipset source should now be ready. Do the following:
KERNEL_DIR=/usr/src/kernel/linux make
KERNEL_DIR=/usr/src/kernel/linux make install
During the execution of the first command there should be one or two
warnings, but no errors. The output of the second command which actually
installs ipset for good should look similar to this:
cp ipset /usr/sbin/ipset
cp ipset.8 /usr/man/man8/ipset.8
cp libipset_ipmap.so /usr/lib/ipset/libipset_ipmap.so
cp libipset_portmap.so /usr/lib/ipset/libipset_portmap.so
cp libipset_macipmap.so /usr/lib/ipset/libipset_macipmap.so
cp libipset_iptree.so /usr/lib/ipset/libipset_iptree.so
cp libipset_iptreemap.so /usr/lib/ipset/libipset_iptreemap.so

The new kernel modules, for some reason, are copied in
/lib/modules/2.6.16.60/extra/, so I do not know why are they not loaded
automatically when the kernel starts and I had to do a modprobe on the
whole lot in that 'extra' directory to force these modules to be loaded
to make it working.
I also did two other things, which I am not sure whether it helped, but
better safe than sorry as they say: I included /usr/lib/ipset/ in
/etc/ld.so.conf as well as executed:
ldconfig /usr/lib/ipset/
to force the loading of all libraries in that directory. And with that
the whole installation process is now complete.
=======================
As I pointed out above, the process should be very similar, if not
identical, for building your version of the kernel/iptables. The
attached ipset-4.4.patch file needs to be tweaked only slightly for
version 4.5 (at least to change "ipset-4.4" to "ipset-4.5") and be
applied before building ipset. Hope this helps!
