Does this patch (on top of unpatched tree) helps?
I can not test it with real hardware, since I'm sicking at home with
laptop only, but I already know how to make a test case for this problem
without complex setup, so if it does not work, I will investigate it
further as

Almost I guess :) There are similar loops in hifn_setup_session().
Additionally we need to check that the return value of ablkcipher_walk()
is not a negative errno code.
Yep. Kind of this one:

It also looks like at least two more changes are needed:

One more thing: I got lots of printk: 4 messages suppressed
without any real messages. The reason is a printk_ratelimit()
before a dprintk(). This probably wants either an #ifdef or
a real printk.

OK that is normal. esp_input is now using the AEAD interface
so the size for

What iv generation scheme do you use? It looks like only gcm and ccm add
16 bytes to cryptlen and set nbytes to them. Although they both install
two scatterlists for crypto operation: one for data and one for above

I'm getting crashes when using HIFN and IPsec (ESP with
AES + MD5) in the current -git tree. I didn't capture the

- hifn_setup_session walks over the scatterlist, subtracting
the scatterlist element size from nbytes until nbytes
reaches zero.
