Hi,
As briefly mentioned in an earlier post, I have issues trying to serve https
(TLS1.0) connections with openssl 1.0.0g and cryptodev-linux.
specs:
- Marvell Kirkwood (armv5)
- Debian Wheezy
- Openssl 1.0.0g debian version recompiled with cryptodev support
(-DHAVE_CRYPTODEV -DUSE_CRYPTODEV_DIGESTS -DHASH_MAX_LEN=64 )
- cryptodev-linux 1.1
When the cryptodev driver is loaded, I get the following backtrace when trying
to initiate a https connection with openssl s_server
(gdb) run s_server -cert default_blank.crt -key default_blank.key -accept 8888
-WWW -tls1

Backtrace stopped: previous frame identical to this frame (corrupt stack?)
When I repeat the same with a break at cryptodev_digest_copy I get the
following output

eng_cryptodev.c:816

This problem has also been posted to openssl-users, here:

my post on cryptodev-linux-devel)
