Description

After Upgrading to v2.13.0.527.g95bf5 openvpn does not work any more
with "engine padlock" enabled in server.conf.

Seems engine padlock in openssl is broken. If I comment out "engine
padlock" from server.conf, handshake works fine.

I X-ed out private info in the certificates.

Try running some standalone tests with openssl itself, and also try
loading or unloading padlock.ko (depending on whether you've loaded it
now or not).

Cheers,
Alex

Please do some tests with 'openssl speed' so we know that this isn't an openvpn issue.

yeah, seems to be an OpenVPN issue rather. Padlock works with openssl speed and clearly accelerates stuff. Also I have set "SSLCryptoDevice padlock" in my apache https configuration and that works, too.
