2022-03-07crypto: add rocksoft 64b crc guard tag frameworkKeith Busch1-0/+15
Hardware specific features may be able to calculate a crc64, so provide a framework for drivers to register their implementation. If nothing is registered, fallback to the generic table lookup implementation. The implementation is modeled after the crct10dif equivalent.

2022-03-03crypto: testmgr - add keygen tests for ffdheXYZ(dh) templatesNicolai Stange1-0/+558
Now that the ffdheXYZ(dh) templates support ephemeral key generation, add ->keygen = 1 TVs for each of them to the testmgr.c. In order to facilitate string merging by the compiler, set party B's secret and public keys to the ones specified for party A in the respective existing known answer test. With GCC 7.5 on x86_64, this leads to an increase of testmgr.o size by less than half a kB.

2022-03-03crypto: dh - remove struct dh's ->q memberNicolai Stange1-10/+6
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.

2019-12-11crypto: testmgr - generate inauthentic AEAD test vectorsEric Biggers1-4/+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.

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.

2019-06-06crypto: xxhash - Implement xxhash supportNikolay Borisov1-0/+106
xxhash is currently implemented as a self-contained module in /lib. 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.

2019-05-30crypto: testmgr - fix length truncation with large page sizeEric Biggers1-5/+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'.

2019-04-18crypto: testmgr - fuzz skciphers against their generic implementationEric Biggers1-1/+1
When the extra crypto self-tests are enabled, test each skcipher algorithm against its generic implementation when one is available. This involves: checking the algorithm properties for consistency, then randomly generating test vectors using the generic implementation and running them against the implementation under test. Both good and bad inputs are tested. This has already detected a bug in the skcipher_walk API, a bug in the LRW template, and an inconsistency in the cts implementations.

2019-04-18crypto: testmgr - expand ability to test for errorsEric Biggers1-5/+15
Update testmgr to support testing for specific errors from setkey() and digest() for hashes; setkey() and encrypt()/decrypt() for skciphers and ciphers; and setkey(), setauthsize(), and encrypt()/decrypt() for AEADs. This is useful because algorithms usually restrict the lengths or format of the message, key, and/or authentication tag in some way. And bad inputs should be tested too, not just good inputs. As part of this change, remove the ambiguously-named 'fail' flag and replace it with 'setkey_error = -EINVAL' for the only test vector that used it -- the DES weak key test vector. Note that this tightens the test to require -EINVAL rather than any error code, but AFAICS this won't cause any test failure. Other than that, these new fields aren't set on any test vectors yet. Later patches will do so. Signed-off-by: Eric Biggers <ebiggers@google.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>

2019-04-18X.509: parse public key parameters from x509 for akcipherVitaly Chikunov1-0/+5
Some public key algorithms (like EC-DSA) keep in parameters field important data such as digest and curve OIDs (possibly more for different EC-DSA variants). Thus, just setting a public key (as for RSA) is not enough. Append parameters into the key stream for akcipher_set_{pub,priv}_key. Appended data is: (u32) algo OID, (u32) parameters length, parameters data. This does not affect current akcipher API nor RSA ciphers (they could ignore it). Idea of appending parameters to the key stream is by Herbert Xu.

2019-04-08crypto: x86/poly1305 - fix overflow during partial reductionEric Biggers1-1/+43
The x86_64 implementation of Poly1305 produces the wrong result on some inputs because poly1305_4block_avx2() incorrectly assumes that when partially reducing the accumulator, the bits carried from limb 'd4' to limb 'h0' fit in a 32-bit integer. This is true for poly1305-generic which processes only one block at a time. However, it's not true for the AVX2 implementation, which processes 4 blocks at a time and therefore can produce intermediate limbs about 4x larger. Fix it by making the relevant calculations use 64-bit arithmetic rather than 32-bit. Note that most of the carries already used 64-bit arithmetic, but the d4 -> h0 carry was different for some reason. To be safe I also made the same change to the corresponding SSE2 code, though that only operates on 1 or 2 blocks at a time. I don't think it's really needed for poly1305_block_sse2(), but it doesn't hurt because it's already x86_64 code. It *might* be needed for poly1305_2block_sse2(), but overflows aren't easy to reproduce there. This bug was originally detected by my patches that improve testmgr to fuzz algorithms against their generic implementation. But also add a test vector which reproduces it directly (in the AVX2 case).

Add 1536 and 4096-byte Adiantum test vectors so that the case where there are multiple NH hashes is tested. This is already tested by the nhpoly1305 test vectors, but it should be tested at the Adiantum level too. Moreover the 4096-byte case is especially important. As with the other Adiantum test vectors, these were generated by the reference Python implementation at https://github.com/google/adiantum and then automatically formatted for testmgr by a script.
