Problem setting up loop back encryption.

Greetings all,

I am attempting to setup loopback encryption, and have everything in
place (I think) but when I actually go to setup the device, I get an
"unsupported encryption type" response. I have the cryptoapi,
cryptoloop, loop and cipher-twofish modules installed, and have
applied all the patches as outlined at www.kerneli.org:8080/cryptoapi
(There was a short article on getting cryptoapi up and running on
2.4.20). The only thing I havn't done is patch util-linux. I have
version 2.11z, but I cannot find a patch for that version. Is this
what I need to do?

Thank you,
Neil

It won't work unless / until you patch util-linux to support encryption.
If you can't get a patch for your version, try the next oldest patch. If
it installs cleanly, compile it and go. If not, you'll have to downgrade
to a patchable version ... or, dig through the code and fix the patch
yourself.

Be careful when playing with util-linux. I recommend installing only the
patched mount, umount and losetup as *-crypto (alongside your existing
binaries) until you're sure they work. Oh, and you only need those 3
(with correspondingly-patched man pages), so don't bother with the rest
of the package.
