2018-03-16crypto: testmgr - add a new test case for CRC-T10DIFArd Biesheuvel1-0/+259
In order to be able to test yield support under preempt, add a test vector for CRC-T10DIF that is long enough to take multiple iterations (and thus possible preemption between them) of the primary loop of the accelerated x86 and arm64 implementations.

2018-02-22crypto: speck - add test vectors for Speck64-XTSEric Biggers1-0/+671
Add test vectors for Speck64-XTS, generated in userspace using C code. The inputs were borrowed from the AES-XTS test vectors, with key lengths adjusted. xts-speck64-neon passes these tests. However, they aren't currently applicable for the generic XTS template, as that only supports a 128-bit block size.

2018-02-22crypto: speck - add support for the Speck block cipherEric Biggers1-0/+128
Add a generic implementation of Speck, including the Speck128 and Speck64 variants. Speck is a lightweight block cipher that can be much faster than AES on processors that don't have AES instructions. We are planning to offer Speck-XTS (probably Speck128/256-XTS) as an option for dm-crypt and fscrypt on Android, for low-end mobile devices with older CPUs such as ARMv7 which don't have the Cryptography Extensions. Currently, such devices are unencrypted because AES is not fast enough, even when the NEON bit-sliced implementation of AES is used. Other AES alternatives such as Twofish, Threefish, Camellia, CAST6, and Serpent aren't fast enough either; it seems that only a modern ARX cipher can provide sufficient performance on these devices. This is a replacement for our original proposal (https://patchwork.kernel.org/patch/10101451/) which was to offer ChaCha20 for these devices. However, the use of a stream cipher for disk/file encryption with no space to store nonces would have been much more insecure than we thought initially, given that it would be used on top of flash storage as well as potentially on top of F2FS, neither of which is guaranteed to overwrite data in-place. Speck has been somewhat controversial due to its origin. Nevertheless, it has a straightforward design (it's an ARX cipher), and it appears to be the leading software-optimized lightweight block cipher currently, with the most cryptanalysis. It's also easy to implement without side channels, unlike AES. Moreover, we only intend Speck to be used when the status quo is no encryption, due to AES not being fast enough. We've also considered a novel length-preserving encryption mode based on ChaCha20 and Poly1305. While theoretically attractive, such a mode would be a brand new crypto construction and would be more complicated and difficult to implement efficiently in comparison to Speck-XTS. There is confusion about the byte and word orders of Speck, since the original paper doesn't specify them. But we have implemented it using the orders the authors recommended in a correspondence with them. The test vectors are taken from the original paper but were mapped to byte arrays using the recommended byte and word orders.

2018-02-22crypto: testmgr - Fix incorrect values in PKCS#1 test vectorConor McLoughlin1-3/+3
The RSA private key for the first form should have version, prime1, prime2, exponent1, exponent2, coefficient values 0. With non-zero values for prime1,2, exponent 1,2 and coefficient the Intel QAT driver will assume that values are provided for the private key second form. This will result in signature verification failures for modules where QAT device is present and the modules are signed with rsa,sha256.

2017-01-13crypto: testmgr - use calculated count for number of test vectorsArd Biesheuvel1-270/+2
When working on AES in CCM mode for ARM, my code passed the internal tcrypt test before I had even bothered to implement the AES-192 and AES-256 code paths, which is strange because the tcrypt does contain AES-192 and AES-256 test vectors for CCM. As it turned out, the define AES_CCM_ENC_TEST_VECTORS was out of sync with the actual number of test vectors, causing only the AES-128 ones to be executed. So get rid of the defines, and wrap the test vector references in a macro that calculates the number of vectors automatically. The following test vector counts were out of sync with the respective defines: BF_CTR_ENC_TEST_VECTORS 2 -> 3 BF_CTR_DEC_TEST_VECTORS 2 -> 3 TF_CTR_ENC_TEST_VECTORS 2 -> 3 TF_CTR_DEC_TEST_VECTORS 2 -> 3 SERPENT_CTR_ENC_TEST_VECTORS 2 -> 3 SERPENT_CTR_DEC_TEST_VECTORS 2 -> 3 AES_CCM_ENC_TEST_VECTORS 8 -> 14 AES_CCM_DEC_TEST_VECTORS 7 -> 17 AES_CCM_4309_ENC_TEST_VECTORS 7 -> 23 AES_CCM_4309_DEC_TEST_VECTORS 10 -> 23 CAMELLIA_CTR_ENC_TEST_VECTORS 2 -> 3 CAMELLIA_CTR_DEC_TEST_VECTORS 2 -> 3 Signed-off-by: Ard Biesheuvel <ard.biesheuvel@linaro.org> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>

In FIPS mode, additional restrictions may apply. If these restrictions are violated, the kernel will panic(). This patch allows test vectors for symmetric ciphers to be marked as to be skipped in FIPS mode. Together with the patch, the XTS test vectors where the AES key is identical to the tweak key is disabled in FIPS mode. This test vector violates the FIPS requirement that both keys must be different.

2015-05-01crypto: pcomp - Constify (de)compression parametersDavid Howells1-1/+1
In testmgr, struct pcomp_testvec takes a non-const 'params' field, which is pointed to a const deflate_comp_params or deflate_decomp_params object. With gcc-5 this incurs the following warnings: In file included from ../crypto/testmgr.c:44:0: ../crypto/testmgr.h:28736:13: warning: initialization discards 'const' qualifier from pointer target type [-Wdiscarded-array-qualifiers] .params = &deflate_comp_params, ^ ../crypto/testmgr.h:28748:13: warning: initialization discards 'const' qualifier from pointer target type [-Wdiscarded-array-qualifiers] .params = &deflate_comp_params, ^ ../crypto/testmgr.h:28776:13: warning: initialization discards 'const' qualifier from pointer target type [-Wdiscarded-array-qualifiers] .params = &deflate_decomp_params, ^ ../crypto/testmgr.h:28800:13: warning: initialization discards 'const' qualifier from pointer target type [-Wdiscarded-array-qualifiers] .params = &deflate_decomp_params, ^ Fix this by making the parameters pointer const and constifying the things that use it.

2014-08-01crypto: testmgr - use chunks smaller than algo block size in chunk testsArd Biesheuvel1-132/+132
This patch updates many of the chunked tcrypt test cases so that not all of the chunks are an exact multiple of the block size. This should help uncover cases where the residue passed to blkcipher_walk_done() is incorrect.
