crypto: tcrypt - fix S/G table for test_aead_speed()

2018-02-13T09:19:49+00:00

commit 5c6ac1d4f8fbdbed65dbeb8cf149d736409d16a1 upstream.

In case buffer length is a multiple of PAGE_SIZE,
the S/G table is incorrectly generated.
Fix this by handling buflen = k * PAGE_SIZE separately.

crypto: tcrypt - fix buffer lengths in test_aead_speed()

2017-12-20T09:10:26+00:00

[ Upstream commit 7aacbfcb331ceff3ac43096d563a1f93ed46e35e ]

Fix the way the length of the buffers used for
encryption / decryption are computed.
For e.g. in case of encryption, input buffer does not contain
an authentication tag.

crypto: tcrypt - remove AES-XTS-192 speed tests

2017-08-03T05:47:20+00:00

Remove xts(aes) speed tests with 2 x 192-bit keys, since implementations
adhering strictly to IEEE 1619-2007 standard cannot cope with key sizes
other than 2 x 128, 2 x 256 bits - i.e. AES-XTS-{128,256}:
[...]
tcrypt: test 5 (384 bit key, 16 byte blocks):
caam_jr 8020000.jr: key size mismatch
tcrypt: setkey() failed flags=200000
[...]

crypto: tcrypt - don't disable irqs and wait

2017-05-18T05:19:48+00:00

The tcrypt AEAD cycles speed tests disables irqs during the test, which is
broken at the very least since commit
'1425d2d17f7309c6 ("crypto: tcrypt - Fix AEAD speed tests")'
adds a wait for completion as part of the test and probably since
switching to the new AEAD API.

While the result of taking a cycle count diff may not mean much on SMP
systems if the task migrates, it's good enough for tcrypt being the quick
& dirty dev tool it is. It's also what all the other (i.e. hash) cycle
speed tests do.

crypto: tcrypt - Add debug prints

2017-01-23T14:50:24+00:00

tcrypt is very tight-lipped when it succeeds, but a bit more feedback
would be useful when developing or debugging crypto drivers, especially
since even a successful run ends with the module failing to insert. Add
a couple of debug prints, which can be enabled with dynamic debug:

Before:

 # insmod tcrypt.ko mode=10
 insmod: can't insert 'tcrypt.ko': Resource temporarily unavailable

After:

 # insmod tcrypt.ko mode=10 dyndbg
 tcrypt: testing ecb(aes)
 tcrypt: testing cbc(aes)
 tcrypt: testing lrw(aes)
 tcrypt: testing xts(aes)
 tcrypt: testing ctr(aes)
 tcrypt: testing rfc3686(ctr(aes))
 tcrypt: all tests passed
 insmod: can't insert 'tcrypt.ko': Resource temporarily unavailable

crypto: tcrypt - Do not bail on EINPROGRESS in multibuffer hash test

2016-07-01T15:45:21+00:00

The multibuffer hash speed test is incorrectly bailing because
of an EINPROGRESS return value.  This patch fixes it by setting
ret to zero if it is equal to -EINPROGRESS.

crypto: tcrypt - Fix memory leaks/crashes in multibuffer hash speed test

2016-06-29T10:12:42+00:00

This patch resolves a number of issues with the mb speed test
function:

* The tfm is never freed.
* Memory is allocated even when we're not using mb.
* When an error occurs we don't wait for completion for other requests.
* When an error occurs during allocation we may leak memory.
* The test function ignores plen but still runs for plen != blen.
* The backlog flag is incorrectly used (may crash).

This patch tries to resolve all these issues as well as making
the code consistent with the existing hash speed testing function.
