* crypto: af_alg - use struct_size() in sock_kfree_s()Gustavo A. R. Silva2019-02-281-2/+1
| | | | | | | | | | | | | | | | | | | Make use of the struct_size() helper instead of an open-coded version in order to avoid any potential type mistakes, in particular in the context in which this code is being used. So, change the following form: sizeof(*sgl) + sizeof(sgl->sg[0]) * (MAX_SGL_ENTS + 1) to : struct_size(sgl, sg, MAX_SGL_ENTS + 1) This code was detected with the help of Coccinelle.

* crypto: adiantum - add 1536 and 4096-byte test vectorsEric Biggers2019-02-221-0/+2860
| | | | | | | | | | | | | | 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.

* crypto: nhpoly1305 - add a test vector with len % 16 != 0Eric Biggers2019-02-221-0/+144
| | | | | | | | | | | | | | This is needed to test that the end of the message is zero-padded when the length is not a multiple of 16 (NH_MESSAGE_UNIT). It's already tested indirectly by the 31-byte Adiantum test vector, but it should be tested directly at the nhpoly1305 level too.

* crypto: testmgr - add iv_out to all CTR test vectorsEric Biggers2019-02-221-0/+45
| | | | | | | | | | | | | | | | | | | | | | | Test that all CTR implementations update the IV buffer to contain the next counter block, aka the IV to continue the encryption/decryption of a larger message. When the length processed is a multiple of the block size, users may rely on this for chaining. When the length processed is *not* a multiple of the block size, simple chaining doesn't work. However, as noted in commit 88a3f582bea9 ("crypto: arm64/aes - don't use IV buffer to return final keystream block"), the generic CCM implementation assumes that the CTR IV is handled in some sane way, not e.g. overwritten with part of the keystream. Since this was gotten wrong once already, it's desirable to test for it. And, the most straightforward way to do this is to enforce that all CTR implementations have the same behavior as the generic implementation, which returns the *next* counter following the final partial block. This behavior also has the advantage that if someone does misuse this case for chaining, then the keystream won't be repeated. Thus, this patch makes the tests expect this behavior.

When the extra self-tests are enabled, randomly generated testvec_configs are tested as well.

The new code also tests both the MAY_SLEEP and !MAY_SLEEP cases and buffers that cross pages. This already found bugs in the hash walk code and in the arm32 and arm64 implementations of crct10dif.

* crypto: testmgr - convert aead testing to use testvec_configsEric Biggers2019-02-082-475/+185
| | | | | | | | | | | | | | | | | | | | | | | | | | Convert alg_test_aead() to use the new test framework, using the same list of testvec_configs that skcipher testing uses. This significantly improves AEAD test coverage mainly because previously there was only very limited test coverage of the possible data layouts. Now the data layouts to test are listed in one place for all algorithms and optionally are also randomly generated. In fact, only one AEAD algorithm (AES-GCM) even had a chunked test case before. This already found bugs in all the AEGIS and MORUS implementations, the x86 AES-GCM implementation, and the arm64 AES-CCM implementation. I removed the AEAD chunked test vectors that were the same as non-chunked ones, but left the ones that were unique. Note: the rewritten test code allocates an aead_request just once per algorithm rather than once per encryption/decryption, but some AEAD algorithms incorrectly change the tfm pointer in the request. It's nontrivial to fix these, so to move forward I'm temporarily working around it by resetting the tfm pointer. But they'll need to be fixed.

* crypto: testmgr - introduce CONFIG_CRYPTO_MANAGER_EXTRA_TESTSEric Biggers2019-02-082-0/+24
| | | | | | | | | | | | | | | | | | | | | | | | | | To achieve more comprehensive crypto test coverage, I'd like to add fuzz tests that use random data layouts and request flags. To be most effective these tests should be part of testmgr, so they automatically run on every algorithm registered with the crypto API. However, they will take much longer to run than the current tests and therefore will only really be intended to be run by developers, whereas the current tests have a wider audience. Therefore, add a new kconfig option CONFIG_CRYPTO_MANAGER_EXTRA_TESTS that can be set by developers to enable these extra, expensive tests. Similar to the regular tests, also add a module parameter cryptomgr.noextratests to support disabling the tests. Finally, another module parameter cryptomgr.fuzz_iterations is added to control how many iterations the fuzz tests do. Note: for now setting this to 0 will be equivalent to cryptomgr.noextratests=1. But I opted for separate parameters to provide more flexibility to add other types of tests under the "extra tests" category in the future.

* crypto: testmgr - add testvec_config struct and helper functionsEric Biggers2019-02-081-15/+437
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Crypto algorithms must produce the same output for the same input regardless of data layout, i.e. how the src and dst scatterlists are divided into chunks and how each chunk is aligned. Request flags such as CRYPTO_TFM_REQ_MAY_SLEEP must not affect the result either. However, testing of this currently has many gaps. For example, individual algorithms are responsible for providing their own chunked test vectors. But many don't bother to do this or test only one or two cases, providing poor test coverage. Also, other things such as misaligned IVs and CRYPTO_TFM_REQ_MAY_SLEEP are never tested at all. Test code is also duplicated between the chunked and non-chunked cases, making it difficult to make other improvements. To improve the situation, this patch series basically moves the chunk descriptions into the testmgr itself so that they are shared by all algorithms. However, it's done in an extensible way via a new struct 'testvec_config', which describes not just the scaled chunk lengths but also all other aspects of the crypto operation besides the data itself such as the buffer alignments, the request flags, whether the operation is in-place or not, the IV alignment, and for hash algorithms when to do each update() and when to use finup() vs. final() vs. digest(). Then, this patch series makes skcipher, aead, and hash algorithms be tested against a list of default testvec_configs, replacing the current test code. This improves overall test coverage, without reducing test performance too much. Note that the test vectors themselves are not changed, except for removing the chunk lists. This series also adds randomized fuzz tests, enabled by a new kconfig option intended for developer use only, where skcipher, aead, and hash algorithms are tested against many randomly generated testvec_configs. This provides much more comprehensive test coverage. These improved tests have already exposed many bugs. To start it off, this initial patch adds the testvec_config and various helper functions that will be used by the skcipher, aead, and hash test code that will be converted to use the new testvec_config framework.

* crypto: ahash - fix another early termination in hash walkEric Biggers2019-02-081-7/+7
| | | | | | | | | | | | | | | | Hash algorithms with an alignmask set, e.g. "xcbc(aes-aesni)" and "michael_mic", fail the improved hash tests because they sometimes produce the wrong digest. The bug is that in the case where a scatterlist element crosses pages, not all the data is actually hashed because the scatterlist walk terminates too early. This happens because the 'nbytes' variable in crypto_hash_walk_done() is assigned the number of bytes remaining in the page, then later interpreted as the number of bytes remaining in the scatterlist element.

* crypto: testmgr - skip crc32c context test for ahash algorithmsEric Biggers2019-02-011-4/+10
| | | | | | | | | | | | | | | | | | | | | | Instantiating "cryptd(crc32c)" causes a crypto self-test failure because the crypto_alloc_shash() in alg_test_crc32c() fails. This is because cryptd(crc32c) is an ahash algorithm, not a shash algorithm; so it can only be accessed through the ahash API, unlike shash algorithms which can be accessed through both the ahash and shash APIs. As the test is testing the shash descriptor format which is only applicable to shash algorithms, skip it for ahash algorithms. (Note that it's still important to fix crypto self-test failures even for weird algorithm instantiations like cryptd(crc32c) that no one would really use; in fips_enabled mode unprivileged users can use them to panic the kernel, and also they prevent treating a crypto self-test failure as a bug when fuzzing the kernel.)

* crypto: testmgr - unify the AEAD encryption and decryption test vectorsEric Biggers2019-01-182-6491/+1235
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently testmgr has separate encryption and decryption test vectors for AEADs. That's massively redundant, since usually the decryption tests are identical to the encryption tests, just with the input/result swapped. And for some algorithms it was forgotten to add decryption test vectors, so for them currently only encryption is being tested. Therefore, eliminate the redundancy by removing the AEAD decryption test vectors and updating testmgr to test both AEAD encryption and decryption using what used to be the encryption test vectors. Naming is adjusted accordingly: each aead_testvec now has a 'ptext' (plaintext), 'plen' (plaintext length), 'ctext' (ciphertext), and 'clen' (ciphertext length) instead of an 'input', 'ilen', 'result', and 'rlen'. "Ciphertext" here refers to the full ciphertext, including the authentication tag. For now the scatterlist divisions are just given for the plaintext length, not also the ciphertext length. For decryption, the last scatterlist element is just extended by the authentication tag length. In total, this removes over 5000 lines from testmgr.h, with no reduction in test coverage since prior patches already copied the few unique decryption test vectors into the encryption test vectors. The testmgr.h portion of this patch was automatically generated using the following awk script, except that I also manually updated the definition of 'struct aead_testvec' and fixed the location of the comment describing the AEGIS-128 test vectors. BEGIN { OTHER = 0; ENCVEC = 1; DECVEC = 2; DECVEC_TAIL = 3; mode = OTHER } /^static const struct aead_testvec.*_enc_/ { sub("_enc", ""); mode = ENCVEC } /^static const struct aead_testvec.*_dec_/ { mode = DECVEC } mode == ENCVEC { sub(/\.input[[:space:]]*=/, ".ptext\t=") sub(/\.result[[:space:]]*=/, ".ctext\t=") sub(/\.ilen[[:space:]]*=/, ".plen\t=") sub(/\.rlen[[:space:]]*=/, ".clen\t=") print } mode == DECVEC_TAIL && /[^[:space:]]/ { mode = OTHER } mode == OTHER { print } mode == ENCVEC && /^};/ { mode = OTHER } mode == DECVEC && /^};/ { mode = DECVEC_TAIL } Note that git's default diff algorithm gets confused by the testmgr.h portion of this patch, and reports too many lines added and removed.

* crypto: testmgr - add ccm(aes) decryption tests to encryption testsEric Biggers2019-01-181-1/+196
| | | | | | | | | | | Some "ccm(aes)" decryption test vectors don't exactly match any of the encryption test vectors with input and result swapped. In preparation for removing the AEAD decryption test vectors and testing AEAD decryption using the encryption test vectors, add these to the encryption test vectors, so we don't lose any test coverage.

| | | | | | | | | | In preparation for unifying the AEAD encryption and decryption test vectors, skip AEAD test vectors with the 'novrfy' (verification failure expected) flag set when testing encryption rather than decryption.

Also make the pointers 'const' to make it clearer that nothing is modified. No actual change in behavior.

* crypto: testmgr - split akcipher tests by a key typeVitaly Chikunov2019-01-181-29/+57
| | | | | | | | | | | | | | | | | | | | | | | | Before this, if akcipher_testvec have `public_key_vec' set to true (i.e. having a public key) only sign/encrypt test is performed, but verify/decrypt test is skipped. With a public key we could do encrypt and verify, but to sign and decrypt a private key is required. This logic is correct for encrypt/decrypt tests (decrypt is skipped if no private key). But incorrect for sign/verify tests - sign is performed no matter if there is no private key, but verify is skipped if there is a public key. Rework `test_akcipher_one' to arrange tests properly depending on value of `public_key_vec` and `siggen_sigver_test'. No tests were missed since there is only one sign/verify test (which have `siggen_sigver_test' set to true) and it has a private key, but future tests could benefit from this improvement.

* crypto: shash - remove pointless checks of shash_alg::{export,import}Eric Biggers2019-01-181-4/+2
| | | | | | | | | | | | | | crypto_init_shash_ops_async() only gives the ahash tfm non-NULL ->export() and ->import() if the underlying shash alg has these non-NULL. This doesn't make sense because when an shash algorithm is registered, shash_prepare_alg() sets a default ->export() and ->import() if the implementor didn't provide them. And elsewhere it's assumed that all shash algs and ahash tfms have non-NULL ->export() and ->import(). Therefore, remove these unnecessary, always-true conditions.

* crypto: shash - require neither or both ->export() and ->import()Eric Biggers2019-01-181-0/+3
| | | | | | | | | | | | | Prevent registering shash algorithms that implement ->export() but not ->import(), or ->import() but not ->export(). Such cases don't make sense and could confuse the check that shash_prepare_alg() does for just ->export(). I don't believe this affects any existing algorithms; this is just preventing future mistakes.
