FreeS/WAN + linux crypto in linux 2.4.17

[Marc MERLIN <marc_crypto@merlins.org>]

[Trying again, it didn't go through the first time]

Hi,

So, I was hoping  to get FreeS/WAN to compile as a module  and add it to one
of my kernels.
I then realized that I had to patch my kernel. Would have been easier with a
real patch instead of the dreadful  makefile and patch process which dies if
anything doesn't patch perfectly.
After the pain of working around it, I eventually got the compile to bomb at
the end (fs 1.91 and 2.4.17).

After the pain of working around it, I eventually got the compile to bomb at
the end (see failure at the end of the message)
So, I looked around and found  cryptoapi.sf.net which had the goal of making
crypto a module in an existing kernel.
While  it doesn't  include FS,  I  did find  a promising  freeswan-import.sh
script which seems  to convert the FS  patches into a real patch  that I can
just apply.

However, I  don't think it's  going to  make FS 1.91  work any better  if it
fails to  build now, but  if I like the  features offered by  cryptoapi, and
wouldn't mind  having them in addition  to FS (I  can't tell if it  makes FS
share the cryptoAPI code or if they each have their own).

I guess my main question is can I get FS to work with cryptoapi 2.4.7.0, and
linux 2.4.17? If so, which version of FS should I try to patch?
Can I try to use the freeswan-import.sh script?

Thanks
Marc
