On a SheevaPlug using IPSec when the mv_cesa module is loaded produces
the following oops message:

Which version are you using? I thought this was fixed in 2.6.32.14,
which is part of Debian's 2.6.32-14.

Just on more question: are you sure you're _running_ 2.6.32-5-kirkwood
and not an older one. You can check with: uname -a

There's a bug that causes flash-kernel not be executed when you
install a new kernel, so many people still run the old one... you can
fix this by running:
flash-kernel
reboot

# uname -a
Linux iapetus.saturn.sigsegv.be 2.6.32-5-kirkwood #1 Thu Jun 3 15:54:38 UTC 2010 armv5tel GNU/Linux

Also note this line in the oops:
> [ 114.245137] CPU: 0 Not tainted (2.6.32-5-kirkwood #1)

So, yes, I'm confident I'm running the 2.6.32-5 kernel.

Regards,
Kristof

Default Bug#585790: linux-image-2.6.32-5-kirkwood: Oops in mv_cesa

Hi Sebastian and Herbert,

Kristof Provost reported the following bug against Debian's 2.6.32
kernel package. This package includes Herbert's fix from
http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commitdiff;h=180ce7e81030e1ef763d58f97f9 ab840ff57d848
which I thought fixed this or a similar problem.

Is this a different issue or does the previous fix not work properly?

I had the following patches on top:
750052dd2400cd09e0864d75b63c2c0bf605056f crypto: mv_cesa - Add sha1 and hmac(sha1) async hash drivers
0c5c6c4bae8fe9ae3d86b44c332eb1267df1ec99 crypto: mv_cesa - Support processing of data from previous requests
f0d03deaad05d9cc99cd2ee0475c9ecd726c19ae crypto: mv_cesa - Make the copy-back of data optional
a58094ac5f95d6969e5c52ff096d2fd2864542af crypto: mv_cesa - Execute some code via function pointers rathr than direct calls
7a5f691ef03f4c01d2703b5ec4ddd4c17e645dec crypto: mv_cesa - Rename a variable to a more suitable name
3b61a90502481045f56c1c41a2af35ee48ca8b80 crypto: mv_cesa - Enqueue generic async requests
15d4dd3594221f11a7730fcf2d5f9942b96cdd7e crypto: mv_cesa - Fix situations where the src sglist spans more data than the request asks for
f565e67ec1b8f4a95d21550f9b879fe86b4132e0 crypto: mv_cesa - Fix situation where the dest sglist is organized differently than the source sglist
6bc6fcd609080461682c5cc0a1e3bf4345d6419d crypto: mv_cesa - Remove compiler warning in mv_cesa driver
0328ac267564089d9cedfb568f936d30a6debd21 crypto: mv_cesa - Invoke the user callback from a softirq context

The patches until 0328ac267 to 15d4dd3 are probably required.

Sebastian
