Also, the syntax described is ambiguous. I think you meant for there to be only one set of square brackets? xctr(blockcipher_name) should be xctr_name, since it would have to be a driver / implementation name, and those don't necessarily include parentheses like the algorithm names do. Did you consider not allowing the single block cipher implementation to be overridden? The single block cipher is a minor part compared to xctr. This would simplify the "full" syntax slighty, as then it would be "hctr2(xctr_name, polyval_name)" instead of "hctr2(blockcipher_name, xctr_name, polyval_name)". I suppose it does make sense to take the single block cipher parameter, given that it is used. But you'll need to make sure to make hctr2_create() enforce that the same block cipher is used in both parameters. > diff --git a/crypto/testmgr.h b/crypto/testmgr.h > index da3736e51982..87e4df6f8ea9 100644 > --- a/crypto/testmgr.h > +++ b/crypto/testmgr.h > @@ -33630,4 +33630,791 @@ static const struct hash_testvec polyval_tv_template[] = { > }, > }; > > +/* > + * Test vectors generated using https://github.com/google/hctr2 > + */ > +static const struct cipher_testvec aes_hctr2_tv_template[] = { [snip 787 lines] I think the selection of test vectors still needs some improvemnt. As-is, there are two random test vectors for every permutation of message length in [16, 17, 48, 255] and key length in [16, 24, 32] -- so, 24 test vectors total. However, multiple random test vectors with the same lengths are unlikely to be better than one. Also, testing each AES key length with every message length is unlikely to be useful. Message length is really the main way that things can go wrong in practice. And the real-world case of "long aligned message" is not being tested at all. So I think the test coverage would be better, with fewer test vectors, if more message lengths were tested but there were fewer tests for each length. For example, one test vector for each message length in [16, 17, 31, 48, 64, 128, 255, 512], assigning different AES key lengths to different ones so that all AES key lengths get covered. - Eric

For the single block cipher parameter, another option is to derive it from the xctr_name. That is, once you have the skcipher for xctr_name, you extract its cra_name, assuming that it must be of the form xctr(%s) then you just strip away the xctr() and get the single block cipher name that way. The purpose of having the parameter explicitly is so that the instantiatied algorithm is automatically torn down when the underlying algorithm is replaced with a better version. This is in general unnecessary if you're simply using the single block cipher to generate setup material. Cheers,

So allowing its implementation to be specified might make sense. Alternatively the single block cipher could be emulated with xctr which the template already has, similar to how the cts template only uses cbc, but I think that would be pretty messy here. - Eric

The question is is it performance-critical? Including it as a parameter would be worthwhile if it is. But if its cost is dwarfed by that of the accompanying operations then it might not be worth the complexity. Cheers,

It looks like this is similar to the situation in XTS where I chose not to make it a full parameter during the skcipher conversion: commit f1c131b45410a202eb45cc55980a7a9e4e4b4f40 Author: Herbert Xu <herbert@gondor.apana.org.au> Date: Tue Nov 22 20:08:19 2016 +0800 crypto: xts - Convert to skcipher Cheers,

The x86 implementation operates asynchronously when called in a context where SIMD instructions are unavailable. Perhaps rctx->first_block can be reused, as it's already in the request context? Make sure to test your changes with CONFIG_CRYPTO_MANAGER_EXTRA_TESTS enabled, as that is able to detect this bug (at least when CONFIG_KASAN is also enabled, which I also highly recommend) since it tests calling the crypto algorithms in a context where SIMD instructions cannot be used.

Note that if the meaning of the first parameter to the template will differ (blockcipher_name vs. xctr_name), the full syntax probably should be supported by a separate template called "hctr2_base" rather than by "hctr2", to avoid having the meaning of the first parameter be context-dependent. This would be like gcm and gcm_base. So we'd have e.g.: hctr2(aes) hctr2_base(xctr-aes-aesni,polyval-pclmulqdqni) cra_name would be set to the former, while cra_driver_name would be set to the latter. - Eric

To be pedantic, AFAIK if the first version of a file was written in 2021, then it's correct to write 2021 even if it wasn't "published" yet. But writing 2022 instead would also be fine if updates were made in 2022 (and I'd recommend just doing that, to prevent people from thinking it's the wrong year :-) ). - Eric

Add support for HCTR2 as a template. HCTR2 is a length-preserving encryption mode that is efficient on processors with instructions to accelerate AES and carryless multiplication, e.g. x86 processors with AES-NI and CLMUL, and ARM processors with the ARMv8 Crypto Extensions. As a length-preserving encryption mode, HCTR2 is suitable for applications such as storage encryption where ciphertext expansion is not possible, and thus authenticated encryption cannot be used. Currently, such applications usually use XTS, or in some cases Adiantum. XTS has the disadvantage that it is a narrow-block mode: a bitflip will only change 16 bytes in the resulting ciphertext or plaintext. This reveals more information to an attacker than necessary. HCTR2 is a wide-block mode, so it provides a stronger security property: a bitflip will change the entire message. HCTR2 is somewhat similar to Adiantum, which is also a wide-block mode. However, HCTR2 is designed to take advantage of existing crypto instructions, while Adiantum targets devices without such hardware support. Adiantum is also designed with longer messages in mind, while HCTR2 is designed to be efficient even on short messages. HCTR2 requires POLYVAL and XCTR as components.
