2015-09-11crypto: testmgr - don't copy from source IV too muchAndrey Ryabinin
While the destination buffer 'iv' is MAX_IVLEN size, the source 'template[i].iv' could be smaller, thus memcpy may read read invalid memory. Use crypto_skcipher_ivsize() to get real ivsize and pass it to memcpy. Signed-off-by: Andrey Ryabinin <aryabinin@virtuozzo.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>

2015-06-17Revert "crypto: testmgr - Disable rfc4543 test"Herbert Xu
This reverts commit 9b9f9296a7b73fbafe0a0a6f2494eaadd97f9f73 as all in-kernel implementations of GCM have been converted to the new AEAD interface, meaning that they should now pass the updated rfc4543 test. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
2015-06-17crypto: testmgr - Disable rfc4543 testHerbert Xu
Because the old rfc4543 implementation always injected an IV into the AD, while the new one does not, we have to disable the test while it is converted over to the new AEAD interface. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>

2015-05-27crypto: jitterentropy - add jitterentropy RNGStephan Mueller
The CPU Jitter RNG provides a source of good entropy by collecting CPU executing time jitter. The entropy in the CPU execution time jitter is magnified by the CPU Jitter Random Number Generator. The CPU Jitter Random Number Generator uses the CPU execution timing jitter to generate a bit stream which complies with different statistical measurements that determine the bit stream is random. The CPU Jitter Random Number Generator delivers entropy which follows information theoretical requirements. Based on these studies and the implementation, the caller can assume that one bit of data extracted from the CPU Jitter Random Number Generator holds one bit of entropy. The CPU Jitter Random Number Generator provides a decentralized source of entropy, i.e. every caller can operate on a private state of the entropy pool. The RNG does not have any dependencies on any other service in the kernel. The RNG only needs a high-resolution time stamp. Further design details, the cryptographic assessment and large array of test results are documented at http://www.chronox.de/jent.html.

2015-01-13crypto: testmgr - don't use interruptible wait in testsRabin Vincent
tcrypt/testmgr uses wait_for_completion_interruptible() everywhere when it waits for a request to be completed. If it's interrupted, then the test is aborted and the request is freed. However, if any of these calls actually do get interrupted, the result will likely be a kernel crash, when the driver handles the now-freed request. Use wait_for_completion() instead.

The DRBG test code implements the CAVS test approach. As discussed for the test vectors, all DRBG types are covered with testing. However, not every backend cipher is covered with testing. To prevent the testmgr from logging missing testing, the NULL test is registered for all backend ciphers not covered with specific test cases. All currently implemented DRBG types and backend ciphers are defined in SP800-90A. Therefore, the fips_allowed flag is set for all.
