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 - 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;

crypto: tcrypt - Add speed tests for SHA multibuffer algorithms

2016-06-27T08:57:46+00:00

The existing test suite to calculate the speed of the SHA algorithms
assumes serial (single buffer)) computation of data. With the SHA
multibuffer algorithms, we work on 8 lanes of data in parallel. Hence,
the need to introduce a new test suite to calculate the speed for these
algorithms.
