Feature request: ip_set for non-modular kernel

[Ed W]

Hi, Love the ip_set features - any chance that you might provide the
code (or possibly just instructions?) to build into the kernel in a
non-modular fashion? (for 2.6.38 and earlier)

The use case is a small embedded platform that has a slow modprobe
performance and modprobing at boottime directly affects the perceived
boot time speed (ie that's what I need to optimise).  Additionally it
helps with my build scripts - not your concern, but it would simplify my
build scripts

Thanks for your consideration!

I was able to successfully achieve just that with version 4.5 and kernel 
2.6.35 (kernel compiled from source, of course). If you have ipset 4.5 
there is a nifty script called patch_kernel in the kernel/ directory 
which does the donkey work for you - i.e. copying the necessary files to 
the kernel source directory and adjust the appropriate kernel Kbuild and 
Makefile(s).

What is left to be done by you then is to run "make oldconfig" (or amend 
the ipset kernel options manually, if you wish) and adjust the ipset 
kernel options so that all ipset files are included in the kernel, not 
as modules (in other words, set all ipset-related kernel options to "y" 
as oppose to "m").

In version 6 and above, the job is a tad more difficult as I am not sure 
you can build the ipset objects as part of the kernel - I have 
successfully built them as modules (as part of the kernel compilation), 
but have not tried to include them as part of the kernel itself - I am 
waiting for Jozsef to fix the bug I found in v6.3 and I will then 
upgrade all my systems to that version (I am still on 4.5 at present). 
Good luck!
