Herbert Xu 50d2b643ea crypto: testmgr - Allow leading zeros in RSA
This patch allows RSA implementations to produce output with
leading zeroes.  testmgr will skip leading zeroes when comparing
the output.

This patch also tries to make the RSA test function generic enough
to potentially handle other akcipher algorithms.

Herbert Xu df27b26f04 crypto: testmgr - Use kmalloc memory for RSA input
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.

Stephan Mueller bb5530e408 crypto: jitterentropy - add jitterentropy RNG
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.

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.

Stephan Mueller 64d1cdfbe2 crypto: drbg - Add DRBG test code to testmgr
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.

Instruction (vpgatherdd) that this implementation relied on turned out to be
slow performer on real hardware (i5-4570). The previous 8-way twofish/AVX
implementation is therefore faster and this implementation should be removed.

Converting this implementation to use the same method as in twofish/AVX for
table look-ups would give additional ~3% speed up vs twofish/AVX, but would
hardly be worth of the added code and binary size.

Jussi Kivilinna 8163fc30d1 crypto: testmgr - add new larger DES testvectors
Most DES testvectors are short and do not test parallelised codepaths
well. Add larger testvectors to test large crypto operations and to test
multi-page crypto with DES.

Johannes Goetzfried 4ea1277d30 crypto: cast6 - add x86_64/avx assembler implementation
This patch adds a x86_64/avx assembler implementation of the Cast6 block
cipher. The implementation processes eight blocks in parallel (two 4 block
chunk AVX operations). The table-lookups are done in general-purpose registers.
For small blocksizes the functions from the generic module are called. A good
performance increase is provided for blocksizes greater or equal to 128B.

Patch has been tested with tcrypt and automated filesystem tests.

Jarod Wilson 18c0ebd2d8 crypto: testmgr - mark ghash as fips_allowed
A self-test failure in fips mode means a panic. Well, gcm(aes)
self-tests currently fail in fips mode, as gcm is dependent on ghash,
which semi-recently got self-test vectors added, but wasn't marked as a
fips_allowed algorithm. Because of gcm's dependence on what is now seen
as a non-fips_allowed algorithm, its self-tests refuse to run.
Previously, ghash got a pass in fips mode, due to the lack of any test
vectors at all, and thus gcm self-tests were able to run. After this
patch, a 'modprobe tcrypt mode=35' no longer panics in fips mode, and
successful self-test of gcm(aes) is reported.

Set the fips_allowed flag in testmgr.c's alg_test_descs[] for algs

One caveat: des isn't actually allowed anymore, but des (and thus also
ecb(des)) has to be permitted, because disallowing them results in
des3_ede being unable to properly register (see des module init func).

Also, crc32 isn't technically on the fips approved list, but I think
it gets used in various places that necessitate it being allowed.

This list is based on

Herbert Xu f8b0d4d09d crypto: testmgr - Dynamically allocate xbuf and axbuf
We currently allocate temporary memory that is used for testing
statically.  This renders the testing engine non-reentrant. As
algorithms may nest, i.e., one may construct another in order to
carry out a part of its operation, this is unacceptable.  For
example, it has been reported that an AEAD implementation allocates
a cipher in its setkey function, which causes it to fail during
testing as the temporary memory is overwritten.

This patch replaces the static memory with dynamically allocated
buffers.  We need a maximum of 16 pages so this slightly increases
the chances of an algorithm failing due to memory shortage.
However, as testing usually occurs at registration, this shouldn't
be a big problem.
