How to adapt a kernel patch to a newer Kernel ?

[Momken]

Hello all,

I am working on Mobile IPv6, afaik newer kernels do not support it.

I found a patch online for kernel 2.6.16.20 I was wondering how can I adapt it to the current version.

Thanks,
S

1. Be or become very good with C
2. Be or become a kernel hacker
3. Understand the patch
4. Modify it for the kernel you want to use

Fwiw, as I am not familiar with Mobile IPv6:
But from looking around, it seems that kernels >= 2.6.26 should have a working implementation.

Thanks for the quick reply, I am afraid the first three points might take some time.

I will look for a way around and update you.

Thanks,

Hello,

I am not sure if this is kernel related at this point, but I will post my question.

I try to install the mip6d software, when i ./configure I get

configure: *** checking for Mobile IPv6 support in kernel headers
checking whether IFA_F_HOMEADDRESS is declared... yes
checking whether RTPROT_MIP is declared... no
configure: error: kernel headers do not support MIPv6.

*** If working Linux kernel headers are not in the default include path,
*** please use CPPFLAGS variable to specify where they can be found
*** (e.g. CPPFLAGS="-isystem /usr/src/linux/include")

But when I look at my kernel capabilities, it looks like it supports it...maybe ...what is m ?

Ok, After following a guide to reconfigure the kernel>

Turns out m is for module.

and

modprobe mip6

loads it !!
