crypto: tcrypt - fix buflen reminder calculation

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

- This fixes the intent of the code to limit the last scatterlist to
  either a full PAGE or a fraction of it, depending on the number of
  pages needed by buflen and the available space advertised by XBUFLEN.

  The original code always sets the last scatterlist to a fraction of a
  PAGE because the first 'if' is never executed.

- Rearrange the second part of the code to remove the conditional from
  the loop

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: tcrypt - Allow speed testing of arbitrary hash functions

2014-12-05T15:57:47+00:00

This patch allows the testing of arbitrary hash functions specified
by the alg module parameter by using them in mode 300 (for sync hash)
and mode 400 (for async hash).

For example, you could do
	modprobe tcrypt mode=300 alg='vmac(aes)'

crypto: tcrypt - print cra driver name in tcrypt tests output

2014-07-03T13:42:09+00:00

Print the driver name that is being tested. The driver name can be
inferred parsing /proc/crypto but having it in the output is
clearer

crypto: testmgr - add aead cbc des, des3_ede tests

2014-05-22T13:03:18+00:00

Test vectors were taken from existing test for
CBC(DES3_EDE). Associated data has been added to test vectors.
HMAC computed with Crypto++ has been used. Following algos have
been covered.

        (a) "authenc(hmac(sha1),cbc(des))"
        (b) "authenc(hmac(sha1),cbc(des3_ede))"
        (c) "authenc(hmac(sha224),cbc(des))"
        (d) "authenc(hmac(sha224),cbc(des3_ede))"
        (e) "authenc(hmac(sha256),cbc(des))"
        (f) "authenc(hmac(sha256),cbc(des3_ede))"
        (g) "authenc(hmac(sha384),cbc(des))"
        (h) "authenc(hmac(sha384),cbc(des3_ede))"

crypto: tcrypt - Fix potential leak in test_aead_speed() if crypto_alloc_aead() fails

2014-04-28T10:21:18+00:00

Fix a potential memory leak in the error handling of test_aead_speed(). In case
crypto_alloc_aead() fails, the function returns without going through the
centralized cleanup path. Reported by Coverity - CID 1163870.
