- update to 1.2.0:
* enhancement: kcapi-hasher: add madvise and 64 bit support by Brandur Simonsen
* fix: fix clang warnding in KDF implementation by Khem Raj
* fix: fix inverted logic in kcapi-main test logic reported by Ondrej Mosnáček
* fix: return error when iteration count is zero for PBKDF as reported by
Guido Vranken
* enhancement: add function kcapi_cipher_stream_update_last to indicate the
last block of a symmetric cipher stream operation
* disable XTS multithreaded tests as it triggers a race discussed in
https://github.com/smuellerDD/libkcapi/issues/92. The conclusion is
the following: xts(aes) doesn't support chaining requests like for other
ciphers such as CBC (at least as implemented in the kernel Crypto API).
That can be seen in `crypto/testmgr.h` - the ciphers that are expected to
return IVs usable for chaining have the `.iv_out` entries filled in in their
test vectors (and those that don't support it do not). One can see that only
CTR and CBC test vectors have them, not XTS.
Looking again at how XTS is defined, it seems one could implement
transparent chaining by simply decrypting the final tweak using the tweak
key and return it as the output IV... but I believe this has never been
mandated nor implemented in the Crypto API (likely because of the overhead
of the final tweak decryption, which would be pointless if you're not going
to use the output IV - and there is currently no way to signal to the driver
that you are going to need it).
* disable AIO parallel tests due to undefined behavior (forwarded request 830821 from dirkmueller)
