[CRYPTO] tcrypt: Forbid tcrypt from being built-in

2006-06-26T07:34:42Z

It makes no sense to build tcrypt into the kernel. In fact, now that the driver init function's return status is being checked, it is in fact harmful to do so. Signed-off-by: Herbert Xu

[CRYPTO] tcrypt: Speed benchmark support for digest algorithms

2006-06-26T07:34:41Z

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. Signed-off-by: Michal Ludvig Signed-off-by: Herbert Xu

[CRYPTO] tcrypt: Return -EAGAIN from module_init()

2006-06-26T07:34:41Z

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? Signed-off-by: Michal Ludvig Signed-off-by: Herbert Xu

[CRYPTO] api: Allow replacement when registering new algorithms

2006-06-26T07:34:41Z

We already allow asynchronous removal of existing algorithm modules. By allowing the replacement of existing algorithms, we can replace algorithms without having to wait for for all existing users to complete. Signed-off-by: Herbert Xu

[CRYPTO] api: Removed const from cra_name/cra_driver_name

2006-06-26T07:34:40Z

We do need to change these names now and even more so in future with instantiated algorithms. So let's stop lying to the compiler and get rid of the const modifiers. Signed-off-by: Herbert Xu

[CRYPTO] api: Added cra_init/cra_exit

2006-06-26T07:34:40Z

This patch adds the hooks cra_init/cra_exit which are called during a tfm's construction and destruction respectively. This will be used by the instances to allocate child tfm's. For now this lets us get rid of the coa_init/coa_exit functions which are used for exactly that purpose (unlike the dia_init function which is called for each transaction). In fact the coa_exit path is currently buggy as it may get called twice when an error is encountered during initialisation. Signed-off-by: Herbert Xu

[CRYPTO] api: Fixed incorrect passing of context instead of tfm

2006-06-26T07:34:40Z

Fix a few omissions in passing TFM instead of CTX to algorithms. Signed-off-by: Michal Ludvig Signed-off-by: Herbert Xu

[CRYPTO] all: Pass tfm instead of ctx to algorithms

2006-06-26T07:34:39Z

Up until now algorithms have been happy to get a context pointer since they know everything that's in the tfm already (e.g., alignment, block size). However, once we have parameterised algorithms, such information will be specific to each tfm. So the algorithm API needs to be changed to pass the tfm structure instead of the context pointer. This patch is basically a text substitution. The only tricky bit is the assembly routines that need to get the context pointer offset through asm-offsets.h. Signed-off-by: Herbert Xu

[CRYPTO] digest: Remove unnecessary zeroing during init

2006-06-26T07:34:38Z

Various digest algorithms operate one block at a time and therefore keep a temporary buffer of partial blocks. This buffer does not need to be initialised since there is a counter which indicates what is and isn't valid in it. Signed-off-by: Herbert Xu

[CRYPTO] digest: Add alignment handling

2006-06-26T07:34:38Z

Some hash modules load/store data words directly. The digest layer should pass properly aligned buffer to update()/final() method. This patch also add cra_alignmask to some hash modules. Signed-off-by: Atsushi Nemoto Signed-off-by: Herbert Xu
