When load aesni-intel and ghash_clmulni-intel driver,kernel will complain no

The strange information as following:

alg: No test for __ecb-aes-aesni (__driver-ecb-aes-aesni)
alg: No test for __cbc-aes-aesni (__driver-cbc-aes-aesni)

alg: No test for __ghash (__ghash-pclmulqdqni)
alg: No test for __ghash (cryptd(__ghash-pclmulqdqni))

As it stands we will each test hash vector both linearly and as
a scatter list if applicable.  This means that we cannot have
vectors longer than a page, even with scatter lists.

This patch fixes this by skipping test vectors with np != 0 when
testing linearly.
Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>

As we cannot guarantee the availability of contiguous pages at
run-time, all test vectors must either fit within a page, or use
scatter lists.  In some cases vectors were not checked as to
whether they fit inside a page.  This patch adds all the missing
checks.

Set the fips_allowed flag in testmgr.c's alg_test_descs[] for algs
that are allowed to be used when in fips mode.

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
http://csrc.nist.gov/groups/STM/cavp/index.html



Important note: allowed/approved here does NOT mean "validated", just
that its an alg that *could* be validated.

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.

According to our FIPS CAVS testing lab guru, when we're in fips mode,
we must print out notices of successful self-test completion for
every alg to be compliant.

New and improved v2, without strncmp crap. Doesn't need to touch a flag
though, due to not moving the notest label around anymore.

Applies atop '[PATCH v2] crypto: catch base cipher self-test failures
in fips mode'.

Personally, I wouldn't mind seeing this info printed out regardless of
whether or not we're in fips mode, I think its useful info, but will
stick with only in fips mode for now.

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

This patch creates a new interface algorithm testing.  A test can
be requested for a particular implementation of an algorithm.  This
is achieved by taking both the name of the algorithm and that of
the implementation.

The all-inclusive test has also been rewritten to no longer require
a duplicate listing of all algorithms with tests.  In that process
a number of missing tests have also been discovered and rectified.

The info printed is a complete waste of space when there is no error
since it doesn't tell us anything that we don't already know.  If there
is an error, we can also be more verbose.

In case that there is an error, this patch also aborts the test and
returns the error to the caller.  In future this will be used to
algorithms at registration time.

Patch to add checking  of DES3 test vectors using CBC mode.  FIPS-140-2
compliance mandates that any supported mode of operation must include a self

following command:

	openssl enc -des_ede_cbc -P

input and output values were generated by repeating the string "Too many

openssl using the aformentioned key.  Tested successfully by myself
