2006-06-26[CRYPTO] tcrypt: Speed benchmark support for digest algorithmsMichal Ludvig
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.

2006-06-26[CRYPTO] tcrypt: Return -EAGAIN from module_init()Michal Ludvig
Intentionaly return -EAGAIN from module_init() to ensure it doesn't stay loaded in the kernel. The module does all its work from init() and doesn't offer any runtime functionality => we don't need it in the memory, do we?

2005-10-30[CRYPTO] Simplify one-member scatterlist expressionsHerbert Xu
This patch rewrites various occurences of &sg[0] where sg is an array of length one to simply sg. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
2005-10-30[PATCH] Use sg_set_buf/sg_init_one where applicableDavid Hardeman
This patch uses sg_set_buf/sg_init_one in some places where it was duplicated.

2005-09-01[CRYPTO]: Fix XTEA implementationAaron Grothe
The XTEA implementation was incorrect due to a misinterpretation of operator precedence. Because of the wide-spread nature of this error, the erroneous implementation will be kept, albeit under the new name of XETA.

2005-06-22[CRYPTO]: Use CPU cycle counters in tcryptHerbert Xu
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.

2005-06-22[CRYPTO]: Use template keys for speed tests if possibleHerbert Xu
The existing keys used in the speed tests do not pass the 3DES quality check. This patch makes it use the template keys instead. Other algorithms can supply template keys through the same interface if needed. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au> Signed-off-by: David S. Miller <davem@davemloft.net>
2005-06-22[CRYPTO]: Add cipher speed testsHarald Welte
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.

2005-06-22[CRYPTO]: Kill unnecessary strncpy from tcryptHerbert Xu
It seems that bad code tends to get copied (see test_cipher_speed). So let's kill this idiom before it spreads any further. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au> Signed-off-by: David S. Miller <davem@davemloft.net>

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!
