(using this version from ftp.kernel.org/pub/linux/utils/util-linux: -rw-r--r-- 1 korg korg 1285674 Jul 13 22:09 util-linux-2.12pre.tar.bz2
Umm.. OK... I'll bite. How do I get 2.12pre to actually use cryptoloop?
Ah, 2.12pre is not 2.12.
(2.12pre is a solid version, I hope, nothing wrong with it, but no new loop stuff; someone was willing to test it and did not come back with complaints, so maybe it isnt too bad.)
(On the other hand, concerning 2.12 I hesitated for a long time. Jari came with code that works perfectly, but is such a lot of cruft. Did I really want to maintain that? Lots of cryptoalgorithms built into mount? On ftp.cwi.nl under /pub/aeb/util-linux there was a util-linux-2.12-wip.tar.gz for a month or so, but I removed it and replaced it by util-linux-2.12.tar.gz. This new losetup/mount is minimal instead of maximal, smaller than the older versions. Good for playing, but people who really have their filesystems on loop-aes or cryptoloop had better wait before rushing and installing this.)
A main reason for discrepancy is that no knowledge about cryptoalgorithms is built into mount/losetup. With a -p option these programs are willing to read a possibly encrypted passphrase from a given file descriptor. All passphrase handling can now be external to mount, I hope. No doubt more polishing is needed.
Nothing has been tested. (But it compiles here.)
Please test and report.
