* crypto: api - Disallow cryptomgr as a module if algorithms are built-inHerbert Xu2008-12-102-13/+41
| | | | | | | | | | | | | If we have at least one algorithm built-in then it no longer makes sense to have the testing framework, and hence cryptomgr to be a module. It should be either on or off, i.e., built-in or disabled. This just happens to stop a potential runaway modprobe loop that seems to trigger on at least one distro. With fixes from Evgeniy Polyakov.

| * crypto: skcipher - Use RNG interface instead of get_random_bytesHerbert Xu2008-08-294-13/+75
| | | | | | | | | | | | | | This patch makes the IV generators use the new RNG interface so that the user can pick an RNG other than the default get_random_bytes. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>

| | | | | | | | | | | | | | | | | | | | | | | | This patch adds a random number generator interface as well as a cryptographic pseudo-random number generator based on AES.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add the ability to turn FIPS-compliant mode on or off at boot In order to be FIPS compliant, several check may need to be preformed that may be construed as unusefull in a non-compliant mode. This patch allows us to set a kernel flag incating that we are running in a fips-compliant mode from boot up. It also exports that mode information to user space via a sysctl (/proc/sys/crypto/fips_enabled). Tested successfully by me.

| | | | | | | | | | | | | | | | | | | | | | | | | | This patch creates a new interface algorithm testing. A test can be requested for a particular implementation of an algorithm. This is achieved by taking both the name of the algorithm and that of the implementation. The all-inclusive test has also been rewritten to no longer require a duplicate listing of all algorithms with tests. In that process a number of missing tests have also been discovered and rectified. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>

If there is an error, we can also be more verbose. In case that there is an error, this patch also aborts the test and returns the error to the caller.

|/ | | | | | | | | | | | | | Should clear the next pointer of the TX if we are sure that the next TX (say NXT) will be submitted to the channel too. Overwise, we break the chain of descriptors, because we lose the information about the next descriptor to run.

* crypto: authenc - Avoid using clobbered request pointerHerbert Xu2008-08-221-4/+6
| | | | | | | | | | | | | | | | | | Authenc works in two stages for encryption, it first encrypts and then computes an ICV. The context memory of the request is used by both operations. The problem is that when an asynchronous encryption completes, we will compute the ICV and then reread the context memory of the encryption to get the original request. It just happens that we have a buffer of 16 bytes in front of the request pointer, so ICVs of 16 bytes (such as SHA1) do not trigger the bug. However, any attempt to uses a larger ICV instantly kills the machine when the first asynchronous encryption is completed. This patch fixes this by saving the request pointer before we start the ICV computation. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>

Tested with iop-adma by setting device->max_xor = 2 to force multiple calls to device_prep_dma_xor for each call to async_xor and limiting the descriptor slot pool to 5.

| * async_tx: ensure the xor destination buffer remains dma-mappedDan Williams2008-07-181-131/+113
| | | | | | | | | | | | | | | | | | | | | | | | | | | | When the number of source buffers for an xor operation exceeds the hardware channel maximum async_xor creates a chain of dependent operations. The result of one operation is reused as an input to the next to continue the xor calculation. The destination buffer should remain mapped for the duration of the entire chain. To provide this guarantee the code must no longer be allowed to fallback to the synchronous path as this will preclude the buffer from being unmapped, i.e. the dma-driver will potentially miss the descriptor with !DMA_COMPL_SKIP_DEST_UNMAP.

This is done because list are a very used primitive structure all over the kernel and it's currently impossible to include other header files in this list.h without creating some circular dependencies. For example, list.h implements rcu-protected list and uses rcu_dereference() without including rcupdate.h. It actually compiles because users of rcu_dereference() are macros. Others RCU functions could be used too but aren't probably because of this. Therefore this patch creates rculist.h which includes rcupdates without to many changes/troubles.
