kernel 2.6.24.3 patches for AX25

kernel 2.6.24.3 patches for AX25

[Bernard Pidoux F6BVP]

Hi All,

Participating in AX25, ROSE, FPAC, and LinFBB debugging, I want to share 
with you the recent progress accomplished with Linux kernel.

While the code is not yet fully debugged, there have been significant 
progress and I summarized them into two patches that, when applied to 
kernel 2.6.24.3, lead to a much more stable system.

The two patches must be applied one after the other.

First one is here :
http://f6bvp.free.fr/logiciels/ax25/patch-2.6.24.3-net_rose_ax25

I have already reported it to a few OMs running FPAC application.
It was here : 
http://f6bvp.free.fr/logiciels/rose-fpac/patch-2.6.24.3.ax25.tgz

Do not try to apply the first patch if the original kernel source have 
been already patched.

Second patch is here :
http://f6bvp.free.fr/logiciels/ax25/patch-2.6.24.3-net_rose_ax25_plus_plus

I am running patched kernels on three different architectures with AX25
applications and the systems are quite stable.
One of them has even a core2 duo CPU and the kernel was compiled with 
SMP option for multiple CPUs.

To apply the patches, you need kernel 2.6.24.3 sources installed and it 
is required that you have already succeeded in compiling the kernel with 
ax25 module.

Save the above files into directory /usr/src
cd into that directory.

Kernel source directory is :

/usr/src/linux-2.6.24.3

Make the following symbolic links if not already present :
ln -s linux-2.6.24.3 linux
ln -s linux a
ln -s linux b

Then apply the patches by typing the following commands :

patch -p0 <  patch-2.6.24.3-net_rose_ax25

patch -p0 <  patch-2.6.24.3-net_rose_ax25_plus_plus


note: in -p0 above 0 is a zero (not letter O).

The cd into linux.
Type the command :

  make


When compilation is finished, type the command :

  make modules_install

And finally, type :

  make install

Then reboot your system.

You are encouraged to send any bug report to linux-hams list.

Mr. Pidoux, et alia:

    Are these patches bound to become part of the Linux kernel in a future
Linux Kernel release or are these patches not yet blessed to be put into the
next Linux Kernel release or never will be?


V/R and 73,

Stuart, N3GWG

Most of the AX25 patches above are to be incorporated in a future kernel 
release.
They were discussed on netdev list and approved by Dave Miller.
There is on:y one that is not yet official, as it is very new and the 
bug it addresses is not yet completily solved.
However, like all others, its purpose is to remove causes of kernel 
panics or crash.
And it works.

By informing refered lists about these patches my goal was to help OMs 
having crash problems when using intensively AX25 applications.
They may safely upgrade to kernel.2.6.24.3 and use the patches provided.
You can also wait a month or two and you will have those patch included 
in kernel 2.6.25 or 2.6.26.

Other part of the patches are related to ROSE module and not yet in the 
future kernels cooker.
I built it after months of intensive experiments, in order to improve 
ROSE routing.
I submitted the patches for ROSE to linux development Netdev list and 
Ralf DL5RB.
I hope that most of them will be accepted for they give us good results 
with FPAC a packet router based on ROSE protocole.

Could you share what particular problems the patches address?  Maybe
send the changelog entries to the list?

Thanks & 73,

When running ax25 applications, linux 2.6 kernels suffers from chronic 
instability leading to kernel panic and system reboot or sudden blockade.
The above mentionned AX25 patches remove the already identified causes 
of kernel locking.
Others are aimed at ROSE network  packet routing improvements.
You may find all the information you want about these patches on Linux 
netdev mailing list archive (MARC) site
 http://marc.info/?l=linux-netdev&r=1&w=2
and search for AX25 or ROSE keyword to select the threads.

Hi,

I have problem that ax25d stops responding to incoming connection after 
some time and then I have to restart ax25d, is there any fix for that in 
patches ?
