MMC Password Protection

This is a simple text-mode reference UI for the MMC password protection
support, written in shell script. It's very simple and does not hash nor cache
passwords.

It's composed of the following files:

- ask_password.sh: get the password from userspace. It's called when unlocking
the card or assigning a new password to an unlocked card.
- change_password.sh: used to change the password from a unlocked card.
- forced_erase.sh: used to force-erase a card, usually when the user has forgot
the password and wants to unlock the card. NOTE: all the card's contents are
lost when using this option! It only works for _locked_ cards.
- remove_password.sh: used to remove the passwor from a card previously unlocked.

Setting up
----------

1) Install the keyutils package available from http://people.redhat.com/~dhowells/keyutils/
2) Install this package:

# make PREFIX=/usr install

2) Add the following lines to /etc/request-key.conf (remember to remove any
previous mmc lines):

create mmc mmc:key unlock /usr/share/keyutils/ask_password.sh %k %S

create mmc mmc:key change /usr/share/keyutils/change_password.sh %k %S
create mmc mmc:key remove /usr/share/keyutils/ask_password.sh %k %S
