crypto: testmgr - fix out of bound read in __test_aead()

2017-06-13T13:29:18+00:00

[ Upstream commit abfa7f4357e3640fdee87dfc276fd0f379fb5ae6 ]

__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.

crypto: testmgr - use CRYPTO_ALG_INTERNAL

2015-03-31T13:21:03+00:00

Allocate the ciphers irrespectively if they are marked as internal
or not. As all ciphers, including the internal ciphers will be
processed by the testmgr, it needs to be able to allocate those
ciphers.

crypto: testmgr - fix RNG return code enforcement

2015-03-13T10:37:15+00:00

Due to the change to RNGs to always return zero in success case, the
invocation of the RNGs in the test manager must be updated as otherwise
the RNG self tests are not properly executed any more.

crypto: testmgr - limit IV copy length in aead tests

2015-02-04T09:59:41+00:00

The working copy of IV is the same size as the transformation's IV.
It is not necessary to copy more than that from the template since
iv_len is usually less than MAX_IVLEN and the rest of the copied data
is garbage.

crypto: testmgr - mark rfc4106(gcm(aes)) as fips_allowed

2015-01-26T00:34:32+00:00

This gcm variant is popular for ipsec use, and there are folks who would
like to use it while in fips mode. Mark it with fips_allowed=1 to
facilitate that.

crypto: testmgr - don't use interruptible wait in tests

2015-01-13T11:30:44+00:00

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.

crypto: LLVMLinux: Remove VLAIS usage from crypto/testmgr.c

2014-10-14T08:51:24+00:00

Replaced the use of a Variable Length Array In Struct (VLAIS) with a C99
compliant equivalent. This patch allocates the appropriate amount of memory
using a char array using the SHASH_DESC_ON_STACK macro.

The new code can be compiled with both gcc and clang.
