* crypto: testmgr - populate RSA CRT parameters in RSA test vectorsIgnat Korchagin2022-07-081-21/+100
| | | | | | | | | | | | | | | | | | | | | | Changes from v1: * replace some accidental spaces with tabs In commit f145d411a67e ("crypto: rsa - implement Chinese Remainder Theorem for faster private key operations") we have started to use the additional primes and coefficients for RSA private key operations. However, these additional parameters are not present (defined as 0 integers) in the RSA test vectors. Some parameters were borrowed from OpenSSL, so I was able to find the source. I could not find the public source for 1 vector though, so had to recover the parameters by implementing Appendix C from [1].

* crypto: blake2s - remove shash moduleJason A. Donenfeld2022-06-101-217/+0
| | | | | | | | | | | | | | | | | | | | | | BLAKE2s has no currently known use as an shash. Just remove all of this unnecessary plumbing. Removing this shash was something we talked about back when we were making BLAKE2s a built-in, but I simply never got around to doing it. So this completes that project. Importantly, this fixs a bug in which the lib code depends on crypto_simd_disabled_for_test, causing linker errors. Also add more alignment tests to the selftests and compare SIMD and non-SIMD compression functions, to make up for what we lose from testmgr.c.

* crypto: hctr2 - Add HCTR2 supportNathan Huckleberry2022-06-101-0/+672
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* crypto: polyval - Add POLYVAL supportNathan Huckleberry2022-06-101-0/+171
| | | | | | | | | | | | | | | | | | | | | | Add support for POLYVAL, an ε-Δ-universal hash function similar to GHASH. This patch only uses POLYVAL as a component to implement HCTR2 mode. It should be noted that POLYVAL was originally specified for use in AES-GCM-SIV (RFC 8452), but the kernel does not currently support this mode. POLYVAL is implemented as an shash algorithm. The implementation is modified from ghash-generic.c. For more information on POLYVAL see: Length-preserving encryption with HCTR2: https://eprint.iacr.org/2021/1441.pdf AES-GCM-SIV: Nonce Misuse-Resistant Authenticated Encryption: https://datatracker.ietf.org/doc/html/rfc8452 Signed-off-by: Nathan Huckleberry <nhuck@google.com> Reviewed-by: Eric Biggers <ebiggers@google.com> Reviewed-by: Ard Biesheuvel <ardb@kernel.org> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
* crypto: xctr - Add XCTR supportNathan Huckleberry2022-06-101-0/+693
| | | | | | | | | | | | | | | | | Add a generic implementation of XCTR mode as a template. XCTR is a blockcipher mode similar to CTR mode. XCTR uses XORs and little-endian addition rather than big-endian arithmetic which has two advantages: It is slightly faster on little-endian CPUs and it is less likely to be implemented incorrect since integer overflows are not possible on practical input sizes. XCTR is used as a component to implement HCTR2.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The only current user of the DH KPP algorithm, the keyctl(KEYCTL_DH_COMPUTE) syscall, doesn't set the domain parameter ->q in struct dh. Remove it and any associated (de)serialization code in crypto_dh_encode_key() and crypto_dh_decode_key. Adjust the encoded ->secret values in testmgr's DH test vectors accordingly. Note that the dh-generic implementation would have initialized its struct dh_ctx's ->q from the decoded struct dh's ->q, if present. If this struct dh_ctx's ->q would ever have been non-NULL, it would have enabled a full key validation as specified in NIST SP800-56A in dh_is_pubkey_valid(). However, as outlined above, ->q is always NULL in practice and the full key validation code is effectively dead. A later patch will make dh_is_pubkey_valid() to calculate Q from P on the fly, if possible, so don't remove struct dh_ctx's ->q now, but leave it there until that has happened.

* crypto: testmgr - generate inauthentic AEAD test vectorsEric Biggers2019-12-111-4/+10
| | | | | | | | | | | | | | | | | | | | The whole point of using an AEAD over length-preserving encryption is that the data is authenticated. However currently the fuzz tests don't test any inauthentic inputs to verify that the data is actually being authenticated. And only two algorithms ("rfc4543(gcm(aes))" and "ccm(aes)") even have any inauthentic test vectors at all. Therefore, update the AEAD fuzz tests to sometimes generate inauthentic test vectors, either by generating a (ciphertext, AAD) pair without using the key, or by mutating an authentic pair that was generated. To avoid flakiness, only assume this works reliably if the auth tag is at least 8 bytes. Also account for the rfc4106, rfc4309, and rfc7539esp algorithms intentionally ignoring the last 8 AAD bytes, and for some algorithms doing extra checks that result in EINVAL rather than EBADMSG.

Based on the suggestion from Eric, the following input sizes are tested [0, 1, 7, 15, 64, 247, 256], where blake2b blocksize is 128, so the padded and the non-padded input buffers are tested. blake2b-160 blake2b-256 blake2b-384 blake2b-512 --------------------------------------------------- len=0 | klen=0 klen=1 klen=32 klen=64 len=1 | klen=32 klen=64 klen=0 klen=1 len=7 | klen=64 klen=0 klen=1 klen=32 len=15 | klen=1 klen=32 klen=64 klen=0 len=64 | klen=0 klen=1 klen=32 klen=64 len=247 | klen=32 klen=64 klen=0 klen=1 len=256 | klen=64 klen=0 klen=1 klen=32 Where key: - klen=0: empty key - klen=1: 1 byte value 0x42, 'B' - klen=32: first 32 bytes of the default key, sequence 00..1f - klen=64: default key, sequence 00..3f The unkeyed vectors are ordered before keyed, as this is required by testmgr.

| | | | | | | | | | | | | | | | | | | | | Three variants of AEGIS were proposed for the CAESAR competition, and only one was selected for the final portfolio: AEGIS128. The other variants, AEGIS128L and AEGIS256, are not likely to ever turn up in networking protocols or other places where interoperability between Linux and other systems is a concern, nor are they likely to be subjected to further cryptanalysis. However, uninformed users may think that AEGIS128L (which is faster) is equally fit for use. So let's remove them now, before anyone starts using them and we are forced to support them forever. Note that there are no known flaws in the algorithms or in any of these implementations, but they have simply outlived their usefulness.

This patch enables that module to be used as part of the generic kernel crypto framework. It adds a simple wrapper to the 64bit version. I've also added test vectors (with help from Nick Terrell). The upstream xxhash code is tested by running hashing operation on random 222 byte data with seed values of 0 and a prime number. The upstream test suite can be found at https://github.com/Cyan4973/xxHash/blob/cf46e0c/xxhsum.c#L664 Essentially hashing is run on data of length 0,1,14,222 with the aforementioned seed values 0 and prime 2654435761. The particular random 222 byte string was provided to me by Nick Terrell by reading /dev/random and the checksums were calculated by the upstream xxsum utility with the following bash script: dd if=/dev/random of=TEST_VECTOR bs=1 count=222 for a in 0 1; do for l in 0 1 14 222; do for s in 0 2654435761; do echo algo $a length $l seed $s; head -c $l TEST_VECTOR | ~/projects/kernel/xxHash/xxhsum -H$a -s$s done done done This produces output as follows: algo 0 length 0 seed 0 02cc5d05 stdin algo 0 length 0 seed 2654435761 02cc5d05 stdin algo 0 length 1 seed 0 25201171 stdin algo 0 length 1 seed 2654435761 25201171 stdin algo 0 length 14 seed 0 c1d95975 stdin algo 0 length 14 seed 2654435761 c1d95975 stdin algo 0 length 222 seed 0 b38662a6 stdin algo 0 length 222 seed 2654435761 b38662a6 stdin algo 1 length 0 seed 0 ef46db3751d8e999 stdin algo 1 length 0 seed 2654435761 ac75fda2929b17ef stdin algo 1 length 1 seed 0 27c3f04c2881203a stdin algo 1 length 1 seed 2654435761 4a15ed26415dfe4d stdin algo 1 length 14 seed 0 3d33dc700231dfad stdin algo 1 length 14 seed 2654435761 ea5f7ddef9a64f80 stdin algo 1 length 222 seed 0 5f3d3c08ec2bef34 stdin algo 1 length 222 seed 2654435761 6a9df59664c7ed62 stdin algo 1 is xx64 variant, algo 0 is the 32 bit variant which is currently not hooked up.

| * crypto: testmgr - fix length truncation with large page sizeEric Biggers2019-05-301-5/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | On PowerPC with CONFIG_CRYPTO_MANAGER_EXTRA_TESTS=y, there is sometimes a crash in generate_random_aead_testvec(). The problem is that the generated test vectors use data lengths of up to about 2 * PAGE_SIZE, which is 128 KiB on PowerPC; however, the data length fields in the test vectors are 'unsigned short', so the lengths get truncated. Fix this by changing the relevant fields to 'unsigned int'.
