I noticed that Motorola has published a set of tech docs for their S1-range of crypto co-processors, which look pretty comprehensive. (The 190 looks to be a very nice chip, which -as best as I can tell- just plugs straight onto a PCI bus.) Other co-pro manufacturers (such as HIFN) seem to also have humungous tech manuals for their crypto chips.
Is anyone working on drivers for these beasties?
Alongside that, I also noticed that many manufacturers (again, Motorola and HIFN seem to top the list) working on network accelerator chips - some h/w L2/L3/L4 queueing/filtering, rudimentary packet mangling, etc. Linux already has most of the interesting stuff from the chips I've looked at, and in most places is way more advanced in what it can do/ Given the ipfilter design, would there be any way to use those chips as an additional networking layer? (And, just as importantly, would there be any point?)
Secondly, I've taken a look at the "International Kernel Patch" for Linux. I have finally found a (fairly) mainstream kernel patch that is updated less frequently than my own FOLK patch! Also, nobody seems to use it. Packages that use crypto seem to steer towards openssl, rsa-ref, mcrypt/mhash/gcrypt, gnutls, and/or or private implementations. Even FreeS/WAN and USAGI take no advantage of anything in the IKP.
Ignoring, for a second, the US export laws (which are no longer an issue, anyway), is there some fundamental reason why the IKP seems to be ignored? If there is, then does anyone know of any re-design/re-write effort?
