2016-05-09crypto: testmgr - Use kmalloc memory for RSA inputHerbert Xu1-5/+22
As akcipher uses an SG interface, you must not use vmalloc memory as input for it. This patch fixes testmgr to copy the vmalloc test vectors to kmalloc memory before running the test. This patch also removes a superfluous sg_virt call in do_test_rsa.

2016-05-05crypto: testmgr - Add a flag allowing the self-tests to be disabled at runtime.Richard W.M. Jones1-0/+9
Running self-tests for a short-lived KVM VM takes 28ms on my laptop. This commit adds a flag 'cryptomgr.notests' which allows them to be disabled. However if fips=1 as well, we ignore this flag as FIPS mode mandates that the self-tests are run. Signed-off-by: Richard W.M.

__test_aead() reads MAX_IVLEN bytes from template[i].iv, but the actual length of the initialisation vector can be shorter. The length of the IV is already calculated earlier in the function. Let's just reuses that. Also the IV length is currently calculated several time for no reason. Let's fix that too. This fix an out-of-bound error detected by KASan.

2015-05-27crypto: jitterentropy - add jitterentropy RNGStephan Mueller1-0/+4
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 Vincent1-28/+22
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.
