Hi Kim,
i'm seeing the following oops on ppc (Freescale P1020):

This happens due to the fact that the SEC engine returns NULL in the
CDPR register, so current_desc() returns NULL, which gets dereferenced
in report_eu_error().
I've fixed that with the attached patch, however, i have no idea why the
SEC engine doesn't return a descriptor pointer in CDPR. As i understand
the documentation, it should put the 'currently processed' descriptor
there. Can someone shed some light on this?
Thanks,
Sven

You should have seen the "couldn't locate current descriptor" error
message right before it crashed.

I believe the CDPR may be overwritten by the time the core gets to
it if there is another descriptor queued in the channel's fetch
FIFO. You may be able to glean more information about what happened
by looking at the ISR execution units done/error bits in isr_lo, the
descriptor buffer (displayed at the end of report_eu_error), or the
EU ISRs themselves (see below).
fwiw, I just booted a vanilla 3.1-rc6 kernel on a p1020 with your
config and CONFIG_CRYPTO_MANAGER_DISABLE_TESTS not set, and the
selftests passed. IPSec isn't enabled in your config. Are you
implementing a new algorithm? If not, how to reproduce?

Yes, that message is printed before the oops output. Sorry for cutting
that off in the dmesg output.

Hmm, i don't see that there are any other descriptor queued. But i can
add debug later.

The AESU unit says "data size error", probably because the input data to
aead_decrypt() isn't a multiple of the block size. I'm currently fixing
this in the code. However, i'm not sure if the crypto api or the HW
driver should pad the data to blocksize in such cases.

It is a custom layer 2 tunneling protocol, which doesn't use IPSec.
That's the reson we don't have that option enabled.
Thanks,

It turned out that the reason for this problem was actually a missing
crypto_aead_setauthsize() call. Setting authsize to 20 bytes
(i'm using aead with AES/SHA1) made things work.
However, we should add your patch to the talitos driver, as responding
to such an error with a Kernel OOPS isn't very polite :)
Thanks,
Sven.
The CDPR (Current Descriptor Pointer Register) can be unreliable
when trying to locate an offending descriptor. Handle that case by
(a) not OOPSing, and (b) reverting to the machine internal copy of
the descriptor header in order to report the correct execution unit
error.
Note: printing all execution units' ISRs is not effective because it
results in an internal time out (ITO) error and the EU resetting its
ISR value (at least when specifying an invalid key length on an SEC
2.2/MPC8313E).

please test, as it seems I cannot reproduce the descriptor not found
case.

So what's the verdict Kim, should I take this patch or not?

sure - I've verified it does at least satisfy Sven's shouldn't-oops
comment.
btw, can you take a look at applying this also?:

It makes IPSec AH work for async crypto implementations.
Thanks,
Kim

This needs to go through [email protected].
