* [CRYPTO] scatterwalk: Restore custom sg chaining for nowHerbert Xu2008-01-10
| | | | | | | | Unfortunately the generic chaining hasn't been ported to all architectures yet, and notably not s390. So this patch restores the chainging that we've been using previously which does work everywhere. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
* [CRYPTO] scatterwalk: Move scatterwalk.h to linux/cryptoHerbert Xu2008-01-10
| | | | | | | | The scatterwalk infrastructure is used by algorithms so it needs to move out of crypto for future users that may live in drivers/crypto or asm/*/crypto. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
* [CRYPTO] scatterwalk: Use generic scatterlist chainingHerbert Xu2008-01-10
| | | | | | | This patch converts the crypto scatterwalk code to use the generic scatterlist chaining rather the version specific to crypto. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>

* crypto: don't pollute the global namespace with sg_next()Jens Axboe2007-10-16
| | | | | | | It's a subsystem function, prefix it as such. Acked-by: Herbert Xu <herbert@gondor.apana.org.au> Signed-off-by: Jens Axboe <jens.axboe@oracle.com>
* [CRYPTO] api: Remove deprecated interfaceHerbert Xu2007-02-06
| | | | | | This patch removes the old cipher interface and related code. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
* [CRYPTO] all: Check for usage in hard IRQ contextHerbert Xu2007-02-06
| | | | | | | | | | Using blkcipher/hash crypto operations in hard IRQ context can lead to random memory corruption due to the reuse of kmap_atomic slots. Since crypto operations were never meant to be used in hard IRQ contexts, this patch checks for such usage and returns an error before kmap_atomic is performed.

* [CRYPTO] api: Remove unused functionsAdrian Bunk2006-12-06
| | | | | | | | | | | | This patch removes the following no longer used functions: - api.c: crypto_alg_available() - digest.c: crypto_digest_init() - digest.c: crypto_digest_update() - digest.c: crypto_digest_final() - digest.c: crypto_digest_digest() Signed-off-by: Adrian Bunk <bunk@stusta.de> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
* [CRYPTO] digest: Remove old HMAC implementationHerbert Xu2006-09-20
| | | | | | | | This patch removes the old HMAC implementation now that nobody uses it anymore. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au> Signed-off-by: David S. Miller <davem@davemloft.net>
* [CRYPTO] digest: Added user API for new hash typeHerbert Xu2006-09-20
| | | | | | | | | | | | | | | | | The existing digest user interface is inadequate for support asynchronous operations. For one it doesn't return a value to indicate success or failure, nor does it take a per-operation descriptor which is essential for the issuing of requests while other requests are still outstanding. This patch is the first in a series of steps to remodel the interface for asynchronous operations. For the ease of transition the new interface will be known as "hash" while the old one will remain as "digest". This patch also changes sg_next to allow chaining.

* [CRYPTO] api: Feed flag directly to crypto_yieldHerbert Xu2006-09-20
| | | | | | | | | The sleeping flag used to determine whether crypto_yield can actually yield is really a per-operation flag rather than a per-tfm flag. This patch changes crypto_yield to take a flag directly so that we can start using a per-operation flag instead the tfm flag. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
* [CRYPTO] digest: Store temporary digest in tfmHerbert Xu2006-09-20
| | | | | | | | | When the final result location is unaligned, we store the digest in a temporary buffer before copying it to the final location. Currently that buffer sits on the stack. This patch moves it to an area in the tfm, just like the CBC IV buffer. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
* [CRYPTO] api: Get rid of flags argument to setkeyHerbert Xu2006-09-20
| | | | | | | | | | | | | | | 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.

* [CRYPTO] api: Fixed incorrect passing of context instead of tfmMichal Ludvig2006-06-26

* [CRYPTO] all: Pass tfm instead of ctx to algorithmsHerbert Xu2006-06-26
| | | | | | | | | | | | | | | | 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.

* [CRYPTO] digest: Add alignment handlingAtsushi Nemoto2006-06-26
| | | | | | | | | 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 <anemo@mba.ocn.ne.jp> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>

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!
