Jarod Wilson e08ca2da39 crypto: testmgr - Add ansi_cprng test vectors
Add ANSI X9.31 Continuous Pseudo-Random Number Generator (AES mode),
aka 'ansi_cprng' test vectors, taken from Appendix B.2.9 and B.2.10
of the NIST RNGVS document, found here:
    http://csrc.nist.gov/groups/STM/cavp/documents/rng/RNGVS.pdf

Successfully tested against both the cryptodev-2.6 tree and a Red
Hat Enterprise Linux 5.4 kernel, via 'modprobe tcrypt mode=150'.

The selection of 150 was semi-arbitrary, didn't seem like it should
go any place in particular, so I started a new range for rng tests.

Jarod Wilson 7647d6ce20 crypto: testmgr - Add infrastructure for ansi_cprng self-tests
Add some necessary infrastructure to make it possible to run
self-tests for ansi_cprng. The bits are likely very specific
to the ANSI X9.31 CPRNG in AES mode, and thus perhaps should
be named more specifically if/when we grow additional CPRNG
support...

Successfully tested against the cryptodev-2.6 tree and a
Red Hat Enterprise Linux 5.x kernel with the follow-on
patch that adds the actual test vectors.

Jarod Wilson 5d667322a2 crypto: testmgr - Add self-tests for rfc4309(ccm(aes))
Add an array of encryption and decryption + verification self-tests
for rfc4309(ccm(aes)).

Test vectors all come from sample FIPS CAVS files provided to
Red Hat by a testing lab. Unfortunately, all the published sample
vectors in RFC 3610 and NIST Special Publication 800-38C contain nonce
lengths that the kernel's rfc4309 implementation doesn't support, so
while using some public domain vectors would have been preferred, its
not possible at this time.

Geert Uytterhoeven b812eb0076 crypto: testmgr - Validate output length in (de)compression tests
When self-testing (de)compression algorithms, make sure the actual size of
the (de)compressed output data matches the expected output size.
Otherwise, in case the actual output size would be smaller than the expected
output size, the subsequent buffer compare test would still succeed, and no
error would be reported.

Ingo Molnar 664134d291 crypto: testmgr - Fix error flow of test_comp
This warning:

  crypto/testmgr.c: In function ‘test_comp’:
  crypto/testmgr.c:829: warning: ‘ret’ may be used uninitialized in this function

triggers because GCC correctly notices that in the ctcount == 0 &&
dtcount != 0 input condition case this function can return an undefined
value, if the second loop fails.

Remove the shadowed 'ret' variable from the second loop that was probably
unintended.

Neil Horman d12d6b6d37 crypto: testmgr - Trigger a panic when self test fails in FIPS mode
The FIPS specification requires that should self test for any supported
crypto algorithm fail during operation in fips mode, we need to prevent
the use of any crypto functionality until such time as the system can
be re-initialized.  Seems like the best way to handle that would be
to panic the system if we were in fips mode and failed a self test.
This patch implements that functionality.  I've built and run it
successfully.

Herbert Xu 1aa4ecd95d crypto: cryptomgr - Test ciphers using ECB
As it is we only test ciphers when combined with a mode.  That means
users that do not invoke a mode of operations may get an untested
cipher.

This patch tests all ciphers using the ECB mode so that simple cipher
users such as ansi-cprng are also protected.
