29059d12e0 [CRYPTO] tcrypt: Add missing error check
The return value of crypto_hash_final isn't checked in test_hash_cycles.
This patch corrects this.  Thanks to Eric Sesterhenn for reporting this.

6158efc090 [CRYPTO] tcrypt: Use async blkcipher interface
This patch converts the tcrypt module to use the asynchronous block cipher
interface.  As all synchronous block ciphers can be used through the async
interface, tcrypt is still able to test them.

a28091ae17 [CRYPTO] tcrypt: Added test vectors for sha384/sha512
This patch adds tests for SHA384 HMAC and SHA512 HMAC to the tcrypt module. Test data was taken from
RFC4231. This patch is a follow-up to the discovery (bug 7646) that the kernel SHA384 HMAC
implementation was not generating proper SHA384 HMACs.

Do modprobe tcrypt mode=10 to check the included test vectors, they are

To make the last test vector fit, I had to increase the buffer size of

560c06ae1a [CRYPTO] api: Get rid of flags argument to setkey
Now that the tfm is passed directly to setkey instead of the ctx, we no
longer need to pass the &tfm->crt_flags pointer.

This patch also gets rid of a few unnecessary checks on the key length
for ciphers as the cipher layer guarantees that the key length is within
the bounds specified by the algorithm.

Rather than testing dia_setkey every time, this patch does it only once
during crypto_alloc_tfm.  The redundant check from crypto_digest_setkey
is also removed.

25cdbcd9e5 [CRYPTO] crc32c: Fix unconventional setkey usage
The convention for setkey is that once it is set it should not change,
in particular, init must not wipe out the key set by it.  In fact, init
should always be used after setkey before any digestion is performed.

The only user of crc32c that sets the key is tcrypt.  This patch adds
the necessary init calls there.

e805792851 [CRYPTO] tcrypt: Speed benchmark support for digest algorithms
This patch adds speed tests (benchmarks) for digest algorithms.
Tests are run with different buffer sizes (16 bytes, ... 8 kBytes)
and with each buffer multiple tests are run with different update()
sizes (e.g. hash 64 bytes buffer in four 16 byte updates).
There is no correctness checking of the result and all tests and
algorithms use the same input buffer.

6a17944ca1 [CRYPTO]: Use CPU cycle counters in tcrypt
After using this facility for a while to test my changes to the
cipher crypt() layer, I realised that I should've listend to Dave
and made this thing use CPU cycle counters :) As it is it's too
jittery for me to feel safe about relying on the results.

So here is a patch to make it use CPU cycles by default but fall
back to jiffies if the user specifies a non-zero sec value.

ebfd9bcf16 [CRYPTO]: Add cipher speed tests
From: Reyk Floeter <reyk@vantronix.net>

I recently had the requirement to do some benchmarking on cryptoapi, and
I found reyk's very useful performance test patch [1].

However, I could not find any discussion on why that extension (or
something providing a similar feature but different implementation) was
not merged into mainline.  If there was such a discussion, can someone
please point me to the archive[s]?

I've now merged the old patch into 2.6.12-rc1, the result can be found
attached to this email.

1da177e4c3 Linux-2.6.12-rc2
Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.

Let it rip!
