Hi Sven,
If you mean FEC (forward error correction, using Reed-Solomon code)
support for dm-verity, that's not directly related to LUKS2. In fact
it is kernel feature (and it will be supported in next major veritysetup version,
just the FEC branch need a lot of cleanup before I can merge it).
Anyway, I do not like much the way how it implemented but it is already
in mainline kernel so it is just waste of time to complain again :)
(Read dm-devel if you are interested, thread
"dm verity: add support for error correction" from November last year.)
I have never thought of using FEC for dm-crypt, anyway, if it is implemented
as a separate layer below dmcrypt, it could work (not the case today,
FEC is integral part of dm-verity).
Anyway, if you have some real use cases for FEC (and specifically some
real-world examples of data corruption it can fix), please share it, I am
very interested to see that. (I know the problem exist and that FEC could
be useful but seems nobody is able provide any hard data...)
Milan
