[PATCH 0/4] LUKS1/2 testing in fs-tester and LUKS2 support in grub-probe

[Glenn Washburn <development@efficientek.com>]

This series adds the testing of LUKS 1 and 2 encrypted container to the
user-space fs tester. While this does replicate some of the testing done
by grub_cmd_cryptomount, and is less flexible, it is run natively (that is
without need for virtualization). It also tests the added LUKS2 support in
grub-probe, unlike grub_cmd_cryptomount which does not test any user-space
grub components.

All of these patches have previously been sent to the list. Only patch 4 has
been slightly modified to fix some issues. Since utility of any one is greatly
enhanced, and in the case of patch 4 required, by the others, I think it makes
sense to evaluate them together.

Fabian has noted a memory leak with error handling when using LUKS2 with a
null_cipher[1]. Since this isn't something that I expect to happen in the wild
(why would you use an unencrypted LUKS container?) and even if it does occur
grub-probe is exiting, so the leak would be very short lived, I don't think
this is something that we need to worry about. It wouldn't be that hard to fix
though, just annoying and add a little more complexity to the source.
