* crypto: api - Use test infrastructureHerbert Xu2008-08-295-42/+259
| | | | | | | | This patch makes use of the new testing infrastructure by requiring algorithms to pass a run-time test before they're made available to users. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
* crypto: cryptomgr - Add test infrastructureHerbert Xu2008-08-298-10413/+10525
| | | | | | | | This patch moves the newly created alg_test infrastructure into cryptomgr. This shall allow us to use it for testing at algorithm registrations. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
* crypto: tcrypt - Add alg_test interfaceHerbert Xu2008-08-291-438/+1017
| | | | | | | | | | | | | 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>
* crypto: tcrypt - Abort and only log if there is an errorHerbert Xu2008-08-291-146/+200
| | | | | | | | | | | | The info printed is a complete waste of space when there is no error since it doesn't tell us anything that we don't already know. 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. In future this will be used to algorithms at registration time. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
* crypto: crc32c - Use Intel CRC32 instructionAustin Zhang2008-08-291-0/+12
| | | | | | | | | | | | | From NHM processor onward, Intel processors can support hardware accelerated CRC32c algorithm with the new CRC32 instruction in SSE 4.2 instruction set. The patch detects the availability of the feature, and chooses the most proper way to calculate CRC32c checksum. Byte code instructions are used for compiler compatibility. No MMX / XMM registers is involved in the implementation.

* crypto: tcrypt - Avoid using contiguous pagesHerbert Xu2008-08-292-155/+157
| | | | | | | | | | If tcrypt is to be used as a run-time integrity test, it needs to be more resilient in a hostile environment. For a start allocating 32K of physically contiguous memory is definitely out. This patch teaches it to use separate pages instead. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
* crypto: api - Display larval objects properlyHerbert Xu2008-08-291-2/+5

* crypto: api - Export crypto_alg_lookup instead of __crypto_alg_lookupHerbert Xu2008-08-293-8/+6

* crypto: authenc - Avoid using clobbered request pointerHerbert Xu2008-08-231-4/+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>

* crypto: tcrypt - Fix AEAD chunk testingHerbert Xu2008-08-131-9/+19

In particular, axbuf should really be xbuf. There is also an issue with testing the last segment when encrypting. The additional part produced by AEAD wasn't tested. Similarly, on decryption the additional part of the AEAD input is mistaken for corruption. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>

| | | | | | | | | | | | | | | | | | | | | | | | | | Ensure forward progress is made when a dmaengine driver is unable to allocate an xor descriptor by breaking the dependency chain with async_tx_quisce() and issue any pending descriptors. 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. Discovered that the minimum descriptor pool size for iop-adma is 2 * iop_chan_xor_slot_cnt(device->max_xor) + 1. Signed-off-by: Dan Williams <dan.j.williams@intel.com>
| * async_tx: ensure the xor destination buffer remains dma-mappedDan Williams2008-07-171-131/+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.

| * | | | rcu: split list.h and move rcu-protected lists into rculist.hFranck Bui-Huu2008-05-191-0/+1
| | |_|/ | |/| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Move rcu-protected lists from list.h into a new header file rculist.h. 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.

* | | | crypto: hash - Fixed digest size checkHerbert Xu2008-07-104-9/+13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The digest size check on hash algorithms is incorrect. It's perfectly valid for hash algorithms to have a digest length longer than their block size. For example crc32c has a block size of 1 and a digest size of 4. Rather than having it lie about its block size, this patch fixes the checks to do what they really should which is to bound the digest size so that code placing the digest on the stack continue to work. HMAC however still needs to check this as it's only defined for such algorithms. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
