Re: Linux kernel updates and ip_crossover patch

Hi,

We at IBM need IP CROSSOVER module as part of kernel source.

I sent the request to SuSe for the same and they got back to me and their 
response is in this mail thread below.

Can you please let me know what do you think about IP CROSSOVER feature ?

best regards,
Mehul.

Hello Mehul -

Sorry it has taken me a while to respond. We do not keep any code in 

CMVC.

All code we get from SuSE is on the ftp3 site along with all the source
RPMs. We do have internel CVS trees, but there is no guarantee that 

those

trees are current with the code we get from SuSE which is what your team
should be testing.

As for the htx patch you've provided, I have copied SuSE on this email 

to

get their comments if it can be part of their distribution.

Good morning,

did you sent the patch to netdev@oss.sgi.com?
What opinion have the network and iptables maintainers about this feature?

(See attached file: hxecom_patch)forgot to attach the patch.

updates and ip_crossover patch 

 
 
 



Hi,

We are HTX Team.
We get affected by changes in Linux kernel in a way where we have to 

update

our build environment
continuously. As of now we are doing so manually. But considering the
effort we are thinking of making
it automated.

Can you please tell us if there is a fixed place from where we can sync
Linux kernel sources through
scripts. Or do you put Linux kernel sources in cmvc or any other version
control system.

Also, we have an exerciser named "hxecom" which requires an external 

patch,

ip_crossover for hxecom
 to work in single system test.
This patch helps us in sending packets destined to IP address on the 

same

machine without looping
back at IP layer. Packet actually goes out to hardware and thus we are 

able

to stress network cards.
For this patch to work, kernel should have been compiled with netfilter.
If netfilter is not enabled and ip_crossover patch is not applied, we 

end

up recompiling the whole
stuff and need to copy kernel and /lib/modules on all the test machines,
which is bit ugly.
Can you please include these two request from us in all p-series kernels 

?

I am attaching the patch here.

best regards,
Mehul.
