cryptsetup 2.1.1.2 is not compatible withs 2.1.1.0

[Jaanus Rauk]

Binary package hint: cryptsetup

I-m mounting a volume with following commands:
cryptsetup create crypt /dev/sda3
mount /dev/mapper/crypt /home

After cryptsetup upgrade to '2.1.1.2-1ubuntu1 (maverick)' the mount doesn't recognize media any more.

So I'm stuck with version '2.1.1.0~rc2-1ubuntu13 (lucid)' for now

please read:

iow you must use now
 cryptsetup create -c aes-cbc-plain -s 256 -h ripemd160

Btw if Ubuntu cryptsetup maintainers want to be backward compatible
in stable branch, I suggest reading package release notes and build
package with

configure --with-luks1-keybits=128 --with-plain-mode=cbc-plain

which set default to be fully compatible
(luks change is not problem here, plain mode is)

cryptsetup create -c aes-cbc-plain -s 256 -h ripemd160 crypt /dev/sda3
works for me, thanks.

the changes of default cipher and size have been documented in debian/NEWS. i consider this bug as invalid.
