[PATCH v4 0/2] Have LUKS2 cryptomounts be useable with grub-probe

[Josselin Poiret]

Hello Glenn,

I took the time to rebase all the patches on the latest master, then
remove the problematic parsing, keeping only the cipher part, as well
as add some additional error checking for grub_cryptodisk_setcipher
and grub_crypto_lookup_md_by_name.  I also took note of another mail
saying that we shouldn't pretend to support LUKS3 if it ever comes
out, so I've modified the first patch to only recognize LUKS1 and
LUKS2.  With Fabian's patch [1] applied, this made grub-install
install fine on a LUKS2 drive with a 4096 sector size.

I hope all the logic errors were corrected (removing the complicated
part should have helped).
