Hi,
I try to use geode-aes/CRYPTO_DEV_GEODE, but it gives errors in dmesg
and openssl (see below), and doesn't function.
I found that the change "crypto: cbc - Convert to skcipher" gives the
problem:
https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/crypto/cbc.c?id=79c65d179a40e145287e59b33dc782a7c4bf0986
When I use cbc from before this change, it works fine.
When I use cbc from right after, it doesn't.
(cbc from right after, and from Linux 4.20-rc5, makes no difference in
dmesg, /proc/crypto, openssl).
System is a PC Engines ALIX 2C.2 with Geode LX800, Linux 4.20-rc5.
As it has been broken for a while, I assume there are not many users,
but that might increase at the next Debian stable release.
Thank you,
Gert

Hi Gert and others,
Would it be possible to fix the geode-aes module?
[Wed Oct 2 18:57:38 2019] Error allocating fallback algo cbc(aes)
[Wed Oct 2 18:57:38 2019] alg: skcipher: Failed to load transform for
cbc-aes-geode: -2
[Wed Oct 2 18:57:38 2019] Geode LX AES 0000:00:01.2: GEODE AES engine
enabled.
# uname -a
Linux firewall12 4.19.0-6-686 #1 SMP Debian 4.19.67-2+deb10u1
(2019-09-20) i586 GNU/Linux
# cat /etc/debian_version
10.1
I know it it and old CPU, but I got more then 50 of them still in use
and I can not use a newer kernel anymore, since the cpu load just goes
to 100% without aes hw support.
Kind regards,
Jelle de Jong
