Hi Milan,
Yes, that is correct that the attacks it protects against is when the
underlying storage is offline. We have discussed if we should reset the bitmap
at certain events but decided against it.
Cheers,

Add an option to dm-verity to validate hashes at most once
to allow platforms that is CPU/memory contraint to be
protected by dm-verity against offline attacks.
The option introduces a bitset that is used to check if
a block has been validated before or not. A block can
be validated more than once
