Fwd: Request for review of SCOPE gaps document

[CMS063@xxxxxxxxxxxx (Smarduch Mario-CMS063)]

I just happened to be working with this recently. It appears
a common framework for software and hardware crypto support
is avaialble through cryptoAPI. A crypto alg is abstracted
through 'struct crypto_alg' and registered with 
'crypto_register_alg()'. The module fills in the associated
functions (encr/decr/ecb/cbc) and things like block size,
key size, .. To make use (for example from IPsec setfkey) you
can specify the alg name or driver name, for example "aes"
will choose the first 'aes' alg found or "aes-padlock" will
find the specific driver. IPsec Security Association will
reference that cyrpto_algo for transmit/receive. This holds
for digest as well as cipher algs. The 2.6.22.9 kernel
appears to have couple hardware modules under drivers/crypto.

Jonathan Corbet, the editor of LWN <http://lwn.net/> and the Linux
Weather Forecast <http://www.linux-foundation.org/lwf>, generously gave
the SCOPE gaps document a quick review, attached below.  He can't make
the call today, but hopefully will be able to participate on the next
CGL call.

Unified crypto framework: I don't know as much about this as I would
like to.  The key management infrastructure in the kernel now should be
part of what they want.  There's also quite a bit of crypto capability
in the kernel, including some hardware acceleration support.  I'm not
sure what has been done to export those capabilities to user space,
though.
