Indeed. Just found it here:

HOORAY - it works.

Excellent news !

By the way, has this been accepted in the mainline kernel?


The patches are in 2.6.38.2 just downloaded from kernel.org.

Sure - I am downloading it now.

that is what I am assuming looking at the dates and the fact the i386 kernel

Thank you for the testing.

Odd. I did build both arches. x86_64 was re-rebuilt after the i386
version, which is why it has a newer date.

I will go back to the drawing board and make sure the patches are in place.

If I may ask one more thing ... I think we should continue the current

Glad to hear things worked. Now that a new c6 kernel update is out, I
will try and see if I could include the patches to this version (
2.6.32-71.24.1 ).


I didn't make new patches, I simply did
%define with_fuzzy_patches 1

Never used it. Is it "safe" to do that?


As a general rule probably not. I did examine the result of the patched files 
and verified they
looked OK. I guess I could cp'ed the files that were affected, then applied the 
patch by hand then ran gendiff against the
new and the old to get a new patch, but in the end it is the same thing, other 
than having to turn on with_fuzzy_patches.

Also what should the normal rpmbuild line be?
I ended up doing
rpmbuild -bb --target=`uname -m` kernel.spec --with firmware --without debug
--without debuginfo

The first time I didn't have --with firmware and the kernel wouldn't
install.

Yes, C6 kernels require kernel-firmware. I build it with --target noarch.



Good to know.

I just finished building a kernel based on
kernel-2.6.32-71.18.2.el6.src.rpm. I hand applied the patches. Like you said
one applied clean the other applied with a fuzz offset of -36 (IIRC). I am
installing now to test.

My rebuild was simply cp the /boot/config-2.6.32-71.18.2.el6.i686 to
.config;make oldconfig;make rpm

That is why I was asking about the proper way.

I have just installed the kernel and will now start testing.

Great. Please keep us posted. If the patches work as expected, they
will be a worthy addition to the cplus kernel.

Great. Please keep us posted. If the patches work as expected, they
will be a worthy addition to the cplus kernel.

Hi Akemi,

Two questions:
1) Is there a step by step documentation on rebuilding the centosplus
kernels that includes what the environment should be.

I built all the binaries on RHEL6beta2refresh. Other than that, I hope
that the info on how to build cplus 6 kernel is in that bug tracker
entry.


2) Is it possible to get upstream patches from newer kernels included or
must on do it themselves.

I am specifically interested in the following 2 patches that let linux
behave according to
Basic Requirements for IPv6 Customer Edge Routers
   draft-ietf-v6ops-ipv6-cpe-router-09

The current kernel-2.6.32-71.18.2.el6 does not have these patches - which
prevents using it as
a customer edge router for ipv6.

I had a quick look at the patches. The first one seems to be
applicable without any modifications. The second one will need an
adjustment.

Could you file a request at bugs.centos.org ? I can try and build a
test cplus kernel with those patches applied. Are you then able to
test it to see if the patched version works as expected?

Akemi


I just finished building a kernel based on kernel-2.6.32-71.18.2.el6.src.rpm. I 
hand applied the patches. Like you said
one applied clean the other applied with a fuzz offset of -36 (IIRC). I am 
installing now to test.

My rebuild was simply cp the /boot/config-2.6.32-71.18.2.el6.i686 to 
.config;make oldconfig;make rpm

That is why I was asking about the proper way.

I have just installed the kernel and will now start testing.

Yes, it _could_ affect the centosplus kernel. This point was addressed

It is readily apparent that the build process is very reliant upon 
having "all one's ducks in a row" and one minor version change in a 
dependent source file means the output will not be the binary match with 
the upstream provider that CentOS delivers. Thus the process gives new 
meaning to the word "iterative".


My thanks to all those doing the painstaking work of making it work

I see comments about not being able to rely upon CentOS for business use 
- I beg to differ, I use CentOS for my business and am very satisfied 
with the quality of the product.
There are certainly some business uses where the time-frame of the 
CentOS build process is a problem - if that is the case then there are 
alternatives - they do cost money.
Pay your money and make your choice - no money...accept what is 
CentOS and see if there is somewhere you can contribute to a very

that includes what the environment should be.

2) Is it possible to get upstream patches from newer kernels included or must 
on do it themselves.

I am specifically interested in the following 2 patches that let linux behave

The current kernel-2.6.32-71.18.2.el6 does not have these patches - which 
prevents using it as

From: Thomas Graf
Subject: [PATCH] ipv6: add special mode accept_ra=2 to accept RA while 
configured as router
Date: Friday, September 3, 2010 - 5:59 am

The current IPv6 behavior is to not accept router advertisements while
forwarding, i.e. configured as router.

This does make sense, a router is typically not supposed to be auto
configured. However there are exceptions and we should allow the
current behavior to be overwritten.

Therefore this patch enables the user to overrule the "if forwarding
enabled then don't listen to RAs" rule by setting accept_ra to the
special value of 2.

An alternative would be to ignore the forwarding switch alltogether
and solely accept RAs based on the value of accept_ra. However, I
found that if not intended, accepting RAs as a router can lead to
strange unwanted behavior therefore we it seems wise to only do so
if the user explicitely asks for this behavior.

Similar to accepting router advertisement, the IPv6 stack does not send router

Yes, it _could_ affect the centosplus kernel. This point was addressed
early on when RHEL-6 was released back in Nov 2010. See:
