crypto: tcrypt - fix ghash-generic speed test

2018-11-13T19:16:57+00:00

commit 331351f89c36bf7d03561a28b6f64fa10a9f6f3a upstream.

ghash is a keyed hash algorithm, thus setkey needs to be called.
Otherwise the following error occurs:
$ modprobe tcrypt mode=318 sec=1
testing speed of async ghash-generic (ghash-generic)
tcrypt: test  0 (   16 byte blocks,   16 bytes per update,   1 updates):
tcrypt: hashing failed ret=-126

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

2018-02-13T11:36:02+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()

2017-12-20T09:07:29+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 - 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 - Use skcipher

2016-07-01T15:45:04+00:00

This patch converts tcrypt to use the new skcipher interface as
opposed to ablkcipher/blkcipher.

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.

crypto: tcrypt - Use unsigned long for mb ahash cycle counter

2016-06-28T08:43:40+00:00

For the timescales we are working against there is no need to
go beyond unsigned long.

crypto: tcrypt - Fix mixing printk/pr_err and obvious indentation issues

2016-06-28T08:06:41+00:00

The recently added test_mb_ahash_speed() has clearly serious coding
style issues. Try to fix some of them:
1. Don't mix pr_err() and printk();
2. Don't wrap strings;
3. Properly align goto statement in if() block;
4. Align wrapped arguments on new line;
5. Don't wrap functions on first argument;
