[Ocf-linux-users] Support for stream cipher in OCF

[Rakshith R. <rak...@gm...>]

Hi,
      I am using OCF. I downloaded ocf-20120127 and applied patch to
linux-3.12 kernel, generated cryptodev.ko and cryptosoft.ko, did insmod in
the development board. The problem I am facing is in the development board
I can use only CBC mode of AES alogorithm. It is failing in stream cipher
modes like CFB or OFB. When I give command  'openssl speed -evp
aes-256-cfb' in command line, instead of hardware mode the command got
executed in software mode.
      when I looked into the source code, in file ocf/c7108/aes-7108.c, in
the function c7108_newsession() all other ciphers modes except CBC are
commented out. Is the problem I am facing because of this. Or any other
modification required?

Thank you,
