There might be a trailing newline added by the text editor when
the recovery passphrase was passed using the '--key-file' option
so we'll remove it before trying to use the passphrase.
Some kernels show invalid dm-integrity table if suberblock
contains "recalculate" bit.
We can workaround that by setting recalculate option in table
(kernel uses bits from superblock anyway), so the table displayed
is always correct.

If crypto backend is missing support for hash algorithms used
in PBKDF2 during slot derivatiom the fail was not visible.
Print at least error message to user in this case.
Fixes: #536
LUKS2_hdr_validate() returns positive integer on error. Replace returned
value with negative errno instead so that failed upconversion stops
sooner. It failed anyway but debug messages were misleading.
If LUKS1 payload offset (data offset) is not aligned to
4KiB we create unaligned keyslots area in LUKS2 metadata
during upconversion. Unaligned keyslots area is not valid
from LUKS2 perspective. Fix it by properly aligning future
keyslots area and also check if LUKS1 keyslots area fit
in the new one.
Fixes: #534.
During LUKS2 upconversion we moved binary keyslots area before
validating future LUKS2 header. If later LUKS2 validation failed
for some reason keyslots were already moved to new offsets and
LUKS1 offsets were therefore invalid. Following effort to unlock
such device failed because keyslots were efectively corrupted.
See issue #534.
VeraCrypt now allows passwords of maximal length 128 bytes
(compared to legacy TrueCrypt where it was limited by 64 bytes).
This patch implements support for such a passphrases for TCRYPT format.
The whole extension seems to be quite dubious, the original TCRYPT
passphrase limit was IMO because of internal block length in PBKDF2
(SHA1/SH256 block size is 64 bytes), this patch make sense for SHA512
where the block size is 128 bytes.
Another strange thing is enlarging keyfile pool according to real
entered password size.
Fixes: #532.
With LUKS1 we returned pbkdf values even for inactive keyslot.
Only iterations count was wrong. Remaining values are not
specific keyslot bound with LUKS1.
Fixes: #528.
According to Dislocker, two unknown numbers in the FVE metadata
indicate "state" of the BITLK device. We were able to identify
only one of the states and we shouldn't allow activating devices
in other states for now.
FVE metadata header contains size of the header itself + size of
the metadata entries so we need to take this value and substract
48 (length of the FVE metadata header).
This patch adds CRYPT_VERITY_ROOT_HASH_SIGNATURE flag to verity info.
Veritysetup status now display "with signature" if an active
device was activated with root hash signature.
For this 128 bit Elephant the key data is 512 bit (2 * 156 bit,
same as for 256 bit Elephant) so we need to adjust reading the
key to not include the empty "parts" of the key.
